Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid jetting device and a liquid jetting method using the liquid jetting device. More specifically, the present invention relates to a liquid jetting device for jetting a liquid in a tank toward a peripheral wall of the tank. The present invention relates to a liquid ejecting apparatus and a liquid ejecting method that are sprayed on an inner peripheral surface of a peripheral wall and / or a space above a liquid surface in a tank body.

[0002]

In fermentation and cultivation, the fermentation broth and the culture broth both have a large foaming property, and are frequently foamed due to agitation during the work, often reducing the workability. An antifoaming agent such as silicon is added to each of the fermentation broth and the culture broth in order to prevent such foaming and to eliminate foam once formed. However, the addition of this defoaming agent not only requires a large amount of cost, but also has a high risk of adversely affecting fermentation and cultivation because the defoaming agent itself is a foreign substance, and furthermore, impurities are contained in the product. As it mixes as
The foaming agent must be removed from the product, but removing the foaming agent is troublesome. Also, since the foaming agent added to each of the fermentation broth and the culture broth mixes into the waste liquor and interferes with the waste liquor treatment work, the addition of an antifoaming agent is an undesirable means and should be avoided as much as possible. It is said that there is.

In order to eliminate bubbles, the disk is rotated in the foam layer on the liquid surface, and the truncated cone-shaped hollow cylinder is rotated with the large-diameter lower opening facing the liquid surface in the tank body. Attempts have been made to crush the foam with shear forces by mechanical means such as squeezing. However, such means not only require a great deal of power, but also have the drawback that the foam is simply fragmented and, after all, is often not defoamed.

Further, the inner peripheral surface of the peripheral wall of the stirring tank used as each of the fermentation tank and the culture tank is contaminated by microbial cells and solid raw materials and products adhered to the inner peripheral surface, and In many cases, the yield is reduced or the heat transfer coefficient of the peripheral wall of the stirring tank is reduced. In such a case, in order to remove such deposits from the inner peripheral surface of the stirring tank, it is not possible to clean the inner peripheral surface of the peripheral wall of the stirring tank without stopping the operation in the stirring tank. It is virtually impossible.

As a heating / cooling device for a liquid in a stirring tank used as a crystallization tank or the like, for example, a jacket, a corrugated tube and a multi-tube bundle are each provided with an outer peripheral surface of a peripheral wall of the stirring tank and / or a liquid in the stirring tank. The inner surface of the peripheral wall and / or the surface of the portion immersed in the liquid of the heating / cooling device is used as a heat transfer surface. Decrease by
As the time elapses, the liquid level in the stirring tank decreases, and the heat transfer area of these heating / cooling devices often cannot be used effectively.

In order to increase and recover the reduced heat transfer area, a means for supplying a new liquid into the tank and raising the liquid level and a pump provided outside the tank are used to remove the residual liquid in the tank. There may be a method of circulating and spraying on the inner peripheral surface of the peripheral wall of the tank, which is the heat transfer surface of the heating / cooling means. In the former, such a supply of a new liquid into the tank body causes a sudden change in the composition of the liquid in the tank body, so that a sudden change in operating conditions is necessary to respond to this. There are also disadvantages such as a change in product quality. Further, the latter requires a pump and a pipe for circulating the residual liquid, and has a disadvantage that the residual liquid remains in the tank and the pipe after the operation is stopped. Therefore, the former is a means that cannot be actually adopted, and
The latter needs to be improved in order to be used in practice. As described above, means to be put to practical use for resolving the drawback that the heat transfer area cannot be used effectively has not been found yet.

Furthermore, in order to evaporate the liquid in the stirring tank, usually, a heating means is immersed in the liquid or attached to the outer peripheral surface of the peripheral wall of the stirring tank to stir the liquid. Alternatively, a method of heating the liquid under reduced pressure or under pressure and evaporating the liquid from the liquid surface without stirring is adopted. In this method, the space above the liquid surface of the liquid heated by the heating means is removed. The heat only heats the liquid surface of the liquid only and is not effectively used, and the heating of the liquid in the stirring tank is limited to the contact surface with the heating means and the liquid surface,
There is a disadvantage that the heat of the heating means is not effectively used, and the evaporation rate is reduced accordingly.

[0008] The present inventors have found that the conventional uncertain defoaming due to shearing force, contamination of the inner peripheral surface of the peripheral wall of the stirring tank, reduction of the heat transfer area on the inner peripheral surface of the peripheral wall of the stirring tank, installation in the tank body Overcoming all the drawbacks such as contamination of the heat transfer surface of the heating and cooling device and reduction of the heat transfer area and delay of evaporation of the liquid in the stirring tank only by mechanical stirring, efficiently and
Defoams reliably, cleans the inner peripheral surface of the peripheral wall of the stirring tank, secures the heat transfer area on the inner peripheral surface of the peripheral wall of the stirring tank, cleans and secures the heat transfer surface of the heating / cooling device, and liquids in the stirring tank As a result of intensive studies on a device and a method capable of accelerating the evaporation of water, the inventors arrived at the invention relating to the device and the method and applied for a patent (Japanese Patent Application Laid-Open No. Hei 6-3356).
No. 27 and Japanese Patent Application No. 9-329700).

[0009] The inventors of the present invention use these apparatuses and methods to disperse a sufficient amount of the liquid ejected from the liquid supply in order to spray the liquid in the tank body over the widest possible area of the inner peripheral surface of the tank body peripheral wall. It is necessary to reach as high as possible the inner peripheral surface of the tank body peripheral wall. For this purpose, if the inclination angle of the liquid sending is the same, the liquid sending becomes smaller as the liquid depth becomes shallower and the liquid level decreases. The present inventors have obtained a new finding that the rotation speed of the mounted stirring shaft may be increased, and this can simplify the structure, and have reached the present invention based on this new finding.

[Means for Solving the Problems]

That is, according to the first aspect of the present invention, a liquid sending liquid having a lower opening and an upper opening at a lower end and an upper end, respectively, is mounted on a stirring shaft by a fixture, and the lower opening of the liquid sending is placed below the liquid surface. Submerging, exposing the upper opening of the liquid sending from the liquid surface, rotating the liquid sending about the stirring shaft, and changing the rotation speed according to the fluctuation of the liquid depth in the tank body. The liquid in the liquid immersion part is caused to rise by sending the liquid, and the liquid is ejected from the upper opening of the liquid to be sprayed on the inner peripheral surface of the tank body peripheral wall and / or the space on the liquid surface in the tank body. A liquid ejection device characterized by the above-mentioned.

According to a second aspect of the present invention, the liquid sent from the liquid ejecting apparatus according to the first aspect of the present invention is formed by submerging a lower opening below a liquid surface, exposing the upper opening from the liquid surface, and rotating the liquid about a stirring shaft. The liquid in the liquid immersion part of the liquid sending is raised in the liquid sending, and is ejected from the upper opening of the liquid sending to be sprayed on the inner peripheral surface of the peripheral wall of the tank body and / or the space on the liquid surface in the tank body. The method is a method for ejecting liquid. Unless otherwise specified in the present invention, "up" and "down" are "position far from the liquid bottom" and "position close to the liquid bottom", respectively.
Is defined as

BEST MODE FOR CARRYING OUT THE INVENTION

The attachment is for mounting the liquid to be sent to the stirring shaft. The attachment is a rod-like body, a square bar, a steel plate and a plate-like body with holes (hereinafter, also referred to as a perforated plate-like body), or a plate-like body without perforations. It is preferable that each of the unperforated plate and the perforated plate is horizontally attached to the stirring shaft so that the fluid resistance does not become excessively large when rotated in a liquid. In addition, when the attachment is immersed in the liquid in the tank body, or the portion acts as a stirrer for the liquid.

[0013] These rods, square bars, profiled steel, vertical perforated plates and vertical, non-perforated plates are usually respectively located approximately on the radius or diameter of the plane of rotation. . Further, the center of the horizontal perforated plate-shaped body and that of the horizontal non-perforated plate-shaped body are substantially coincident with the center of the rotation plane. Furthermore, these rods, square bars, shape steel, perforated plates, perforated plates, unperforated plates and the like may be one, but may be plural, and in the case of plural, usually, , May be arranged on the same rotation plane, or may be arranged on different rotation planes.

The position of the liquid spraying on the inner peripheral surface of the peripheral wall of the tank body is set at a radius between the agitating shaft and the circumference of one of the fittings, so that the jetting of the jetting liquid from the upper opening of the liquid sending liquid is performed. Usually, it is sufficient to provide only one liquid feed so as to be within the distance,
It does not prevent providing a plurality of liquid feeds on this radius.

In the liquid jetting device of the present invention, the rotation speed of the stirring shaft is changed in response to the fluctuation of the liquid depth in the tank. For example, as the liquid depth in the tank becomes shallow, By increasing the rotation speed of the stirring shaft, the rotation of the liquid feed is increased. For this purpose, the liquid depth in the tank is detected, and the detected liquid depth is transmitted, for example, via a controller or a computer to a rotational speed transmission mounted on a motor for driving the stirring shaft such as an electric motor. Preferably, the rotation speed of the motor is adjusted to a rotation speed corresponding to the liquid depth. The stirring shaft and the driving motor for driving the stirring shaft are connected to each other directly or indirectly via respective belts and gears.

Further, for example, as the liquid depth in the tank body becomes shallower, the load on the prime mover such as an electric motor and the torque of the stirring shaft become smaller, but the load on the prime mover corresponding to the change in the liquid depth in the tank body becomes smaller. Further, the change in the magnitude of the torque of the stirring shaft can be detected, and can be substituted for the detection of the liquid depth. That is, a current value corresponding to a predetermined magnitude of each of the load of the motor and the torque of the stirring shaft is set in advance (the set current value is hereinafter referred to as a set current value). When the magnitude of the load of the load and the torque of the stirring shaft decrease, and the current value supplied to the motor decreases, the motor is controlled to compensate for the difference between the set current value and the reduced current value. Supply current of the motor is increased, the rotation speed of the motor is increased,
The current supplied to the motor reaches the set current value,
The motor is restored to the rotation speed corresponding to the set current value. In this case, it is preferable that the upper limit of the rotation speed of the electric motor be set arbitrarily in advance so that the rotation speed does not exceed the capacity of the liquid ejection device. Means known per se can be applied to change the rotation speed of the motor in response to a change in the liquid depth.

As a means for detecting the depth of liquid in the tank, a liquid level gauge is usually suitably used. The liquid level gauge is not particularly limited as long as it is a device or device that can detect a change in the liquid level in the tank and can transmit the detected liquid depth. Preferable examples thereof include a differential pressure transmitter such as a differential pressure pilot and a float transmitter such as a float pilot. A commercially available product can be used as the liquid depth detecting means. Further, the liquid depth in the tank can be visually detected, and the rotation speed of the electric motor for driving the stirring shaft can be manually adjusted accordingly.

For detecting the torque of the stirring shaft and the load of the prime mover, usually, a torque meter, a dynamometer and the like are preferably used. Commercially available products can be used for the torque meter and the dynamometer. Representative examples of suitable rotational speed transmissions include a motor equipped with an inverter (hereinafter referred to as an inverter transmission), a Bayer transmission (trade name), and a ring cone transmission (trade name). Above all, an inverter transmission is preferred.

The inverter means a reverse converter, and is a system or a device for converting a direct current into an alternating current. In the inverter transmission, the primary frequency of the AC motor is changed by the inverter, and the rotation speed of the motor is changed. Note that the inverter preferably has a motor stall prevention function. The motor stall prevention function of this inverter detects a change in the liquid depth, a change in the load on the prime mover and a change in the torque of the stirring shaft, and the magnitude of the load on the prime mover and the magnitude of the torque on the stirring shaft become constant. Thus, the rotation speed of the prime mover can be controlled, and stall during operation of the liquid ejection device can be prevented. A commercially available product can be used as the rotation speed transmission.

With the above-mentioned rotational speed transmission, it is possible to automatically control the load of the prime mover and the torque of the stirring shaft so that the respective magnitudes become constant. For this purpose, for example, when the rotational speed transmission is a Bayer transmission, an electric automatic remote control device is mounted in place of the manual transmission handle, and a signal from a dynamometer or a torque meter is transmitted by the electric automatic remote control. When the current value corresponding to the magnitude of the load of the motor and the torque of the stirring shaft sent by this signal is different from the current value preset in the controller, the current value is sent to the controller of the operating device. A signal about the difference is sent to the speed setter, and in response to this signal, the speed setter sends an electric signal to the electric automatic remote control to rotate the shift handle forward or reverse, thereby changing the rotational speed of the Bayer transmission. To increase or decrease the number of revolutions of the electric motor.

In the controller of the electric automatic remote controller, the magnitude of the torque of the stirring shaft or the power of the electric motor sent by the signal from the torque meter or the dynamometer differs from the magnitude of the preset torque or power. Otherwise, the rotation speed of the Bayer transmission, that is, the rotation speed of the electric motor, does not change, and is rotated at a constant speed. Note that a digital controller is usually used as the controller, but an analog controller can also be used.

The controller is also referred to as a blind controller or a controller, has a function of automatically controlling a control amount in an automatic control device, includes a setting unit and a controller, and receives an externally supplied signal. The difference between the value corresponding to the (control amount)-for example, the magnitude of the torque-and the value set in advance in the setting unit is determined by the proportional operation, the differential operation or the integration operation or the proportional operation, the differential operation and the integration in the adjustment unit. This is a control device that emits a signal and adjusts it so that it is reduced by the combination of the three operations. A commercial item can be used as a controller. Also, a controller can be connected to the inverter. In this case, even if the inverter does not have a stall prevention function, the frequency can be changed by a signal from the controller, which is preferable.

The liquid to be sent may be any liquid as long as the liquid can pass therethrough. Usually, a tube, a plate, and a gutter (a tube, a plate, and a gutter are collectively referred to as a thin-type feeder hereinafter) Liquid) and a bottomless hollow cylinder whose long axis is aligned with the stirring axis (hereinafter referred to as cylindrical liquid feed) and a bottomless inverted cone whose long axis is aligned with the stirring axis. (Hereinafter referred to as “inverted truncated conical liquid transfer”) (both cylindrical liquid transfer and inverted truncated conical liquid transfer may be collectively referred to as “thick liquid transfer” below). In the inverted truncated conical liquid transfer, the peripheral wall may be curved with a small curvature. In addition, a cylinder is most preferably used as the cylinder used as the cylinder-type liquid transfer, but a square cylinder such as a square cylinder to an octagonal cylinder may be used. Preferably, the curvature of the peripheral wall is inward.

[0024] As the thin liquid sending, for example,

The lower opening and the upper opening are opened in spaces below the liquid surface and above the liquid surface in the tank, respectively, and serve as an inlet and an outlet for the liquid in the tank, respectively.

In the thin liquid feed, the size of the upper opening and the size of the lower opening may be equal to each other, or may be different from each other. Most preferably, the lower opening is larger than the upper opening. In this case, the ratio between the size of the lower opening and the size of the upper opening is appropriately selected according to the magnitude of the tilt angle of the liquid to be sent, the rotation speed, the head of the ejected liquid, the ejection amount, the type of liquid, and the like. One or a plurality of thin liquid feeds can be arranged in one fixture. In the case where a plurality of thin liquid feeds are provided in one mounting tool, the upper openings and the lower openings of the thin liquid feeds are respectively located on either the substantially same rotation plane or the different rotation plane. It may be opened, but the former is preferred.

The diameter of the body and the truncated cone and the sides or diagonals of the prism and the truncated pyramid may be collectively referred to as "diameter etc." It may be any of a trapezoidal bottomless hollow cylindrical body (hereinafter also referred to as a frustum-shaped cylindrical body). Usually, the frustum-shaped cylinder is preferably used as a frustum-shaped cylinder, with the smaller diameter being the upper side.

The pipe body may be a straight pipe as a whole, but the upper to middle portions are straight pipe portions, the lower portions are bent portions, or the overall shape viewed from the side is substantially S-shaped. Can be. It is practically preferable that the direction of the lower bent portion is slightly downward from vertical or horizontal.
Further, it does not prevent the upper portion of the straight pipe portion from being bent obliquely upward or downward as required to form a bent portion. Each bent portion of the lower and upper portions of the tube can be formed by bending the tube, but another tube is connected to the tip of the straight tube portion of the tube by, for example, welding and screwing. Can also be formed.

The bent portion of the tube body is substantially at 0 to 90 ° with respect to the radial direction of the rotation plane on the rotation plane of the connection point at the junction with the straight pipe portion, that is, the radius of the rotation plane. Above, or along a circumference having a radius equal to the distance from the stirring shaft to the joining point, or along a tangential direction of the circumference, or the entire pipe is moved from the stirring shaft to the pipe. It is possible to bend along an arc of a circle having a radius equal to the distance to the mounting position of the body. Further, the entire tube is formed as a straight tube as a whole when viewed from above or below the rotation plane, and this is attached to the fixture so as to be substantially 0 to 90 ° with respect to the radial direction of the rotation plane as described above. Can also be installed. In addition, no matter what kind of liquid is sent from the trough or the plate, there is essentially no difference from the tube.

The shape of each of the upper opening and the lower opening of the tubular body is not particularly limited.
Circular shapes such as ellipses and ellipses and polygons such as triangles, squares, rectangles, diamonds, hexagons, and octagons. Thus, the respective shapes of the upper opening and the lower opening may be substantially the same as each other, or may be different from each other. Preferably, the lower opening is larger than the upper opening.

The upper opening of the tube may be closed with a perforated plate, and the upper opening may be formed in a funnel shape to form a shower spray type. In this case, the total area of the holes in the perforated plate is the area of the upper opening. The upper opening portion of the tube is a blind tube, and a number of holes are formed as openings therein to form a spray type. In this case, the total area of the large number of holes is the area of the upper opening.

The shape is curved at the curvature. Further, the plate body may be twisted such that the lower or lower end thereof is positioned such that the side to be trailed during the rotation is upward. The upper end edge and the lower end edge of each of the plate and the trough-like body that are the thin liquid transfer correspond to the upper opening and the lower opening of the tube that is the thin liquid transfer, respectively. The upper edge and the lower edge of the plate and the trough, which are thin liquid feeders, are also referred to as an upper opening and a lower opening, respectively.

As a typical example of the asymmetric shape, there is a shape obtained by extending one circumference or side of one end (hereinafter, also referred to as an open end) corresponding to the two opening edges of the above-mentioned symmetric shape (these are the same). Symmetric and asymmetric shapes are sometimes referred to as open shapes below). Also, equilateral angle steel,
The H-shaped steel and a square or rectangular C-shaped steel or a C-shaped steel whose cross-sectional shape lacks one side can be used as the gutter. In particular, type C steel is preferred.

The equilateral angle iron is a trough having an L-shaped opening with a vertical angle at a right angle. The H-section steel is a trough having square or rectangular openings each lacking one side. A C-shaped steel having a rectangular cross-sectional shape is a gutter-shaped body having a rectangular opening lacking a part of one side, and a C-shaped steel having a circular cross-sectional shape is a gutter-shaped body having an opening of a missing circumference. Furthermore, the troughs are, prior to coating or lining, as in coatings or linings known per se,
It is preferable that the edge of the upper surface opening side be rounded or bulged in a columnar shape. In the gutter, the opening area of each of the upper opening and the lower opening is defined as an area through which the liquid can pass through the concave surface (inner peripheral surface) of the gutter.

The opening areas of the upper opening and the lower opening of the gutter-like body are formed by connecting these shapes and both ends of the opening when the shape of the upper opening and the lower opening is a symmetric open shape. It is the area of the closed shape surrounded by a straight line, and when the cross-sectional shape of the upper edge to the upper edge and the lower edge to the lower edge is an asymmetric open shape, these shapes and the ends of the extended portions are The area of the closed shape surrounded by a straight line connecting to the other open end or the area of the closed shape surrounded by a straight line connecting both open ends excluding these shapes and the extension.

There is no particular limitation on the shape of the side surface of the gutter-like body (hereinafter also referred to as a side surface shape), but as a whole, it is usually small so as to bulge straight, upward or downward. The curve curved at the curvature and the straight line and the upper and / or lower ends of said curve may be further S-shaped extending horizontally or below the horizontal direction. The curve is preferably a parabola. Particularly, a straight line is preferable because the gutter-like body can be easily formed. Further, from the viewpoint that the ejection distance and / or the ejection amount of the liquid can be increased, a curve which is swollen downward and is curved is preferable, and a parabola which is swollen downward and is curved is particularly preferable.

The shape of the gutter-shaped body viewed from the front (hereinafter sometimes referred to as the front shape) is not particularly limited, but as a whole shape, it is usually a straight line, a small curvature and a lateral direction (rotation of the gutter-shaped body). Curves curved in a direction parallel to the plane, and so forth) and straight lines and the upper and / or lower ends of said curves may be S-shaped with a further lateral extension, but straight lines are preferred.

Further, the shape of the gutter-like body viewed from above or below (hereinafter, also referred to as a planar shape) is not particularly limited as in the case of each of the above-mentioned side shape and front shape. Usually, a straight line, a curve curved with a small curvature in the direction of rotation or anti-rotation of the gutter-like body, and an S-shape in which the straight line and the upper and / or lower ends of the curve are further extended in the lateral direction. However, straight lines are preferred. The length of the gutter-like body is not particularly limited, but is preferably as long as possible, and is preferably longer than the depth of the liquid layer on which the liquid feed is mounted. The lengths of the plurality of gutter-like bodies attached to the fixture may be the same as each other, or may be different from each other. The side edges of the upper surface openings of the plurality of gutter-like bodies or the walls of the gutter-like bodies are abutted to each other and connected, or the inside of the gutter-like bodies is divided by partition walls provided along its long axis to form a continuous connection. It can be a gutter-like body. The function of this continuous gutter is the same as that of the above-mentioned gutter, and the continuous gutter is included in the gutter.

In order to disperse the liquid from the upper opening of the gutter-like liquid into mist, fine droplets or fine streams, and to eject the liquid, the entire upper opening of the gutter-like body is provided with a perforated plate having a large number of holes formed therein. It can be covered with each of the nets and is preferred.
The perforated plate may have a large number of holes formed regularly or irregularly, and the size, shape and number of holes are not particularly limited. Representative examples of the shape of the hole include a circle, an ellipse, a square, and a rectangle.

Further, the gutter-shaped body may be closed by a plate body with an upper opening having a gap along the inner peripheral surface of the gutter-shaped body. Further, the upper surface opening of the gutter-like body is detachable and can be closed with an opaque or transparent lid. Furthermore, in order to rapidly change the direction of the liquid ejected from the upper opening of the gutter-like body, a reflecting plate can be provided separately from the upper opening.

Further, the gutter-like body is not twisted as long as the liquid can be raised, or does not prevent the gutter from being rotated around its long axis. In this case, the angle at which the gutter is twisted or rotated is appropriately selected depending on the opening shape and the size of the inclination angle of the gutter, the viscosity of the liquid in the container, the rotation speed of the gutter, and the like. .

In the latter case, the gutter-like body may be rotatably mounted on the fixture. In this case, the gutter-shaped body can be fixed after turning to a predetermined deflection angle.
It can be automatically rotated according to the rotation speed of the gutter. In this case, the gutter is rotatably mounted on the stirring shaft.

Further, the trough-shaped body has its concave surface and upper surface opening oriented in the circle or the rotation direction of the plane of rotation of the gutter-shaped body, preferably facing the stirrer shaft or the rotation direction, and being stirred by the fixture. Mounted on shaft. The degree of the respective directions of the concave surface and the upper surface opening of the gutter-like body with respect to the stirring shaft is indicated by the magnitude of the deflection angle. The deflection angle is defined similarly to the deflection angle in dynamics. That is, in the cross section of the opening of the gutter-shaped body or the gutter-shaped body in the plane of rotation, three points arbitrarily selected from the region to be advanced to the region to be made to follow according to the rotation direction,
Let A, B and C be D and the rotation axis (the center of the stirring axis, hereinafter the same) on the same plane as the opening or cross section of the gutter-shaped body, these points A, B and C and D Is satisfied.

That is, (1) distance between B and D ≧ C to D
And (2) the angle between the line segment AB and the base line BD {the angle between the ABD and the line segment BC and the base line BD}
Assuming that the CBD is θ ₁ and θ ₂ respectively, when the gutter is rotated clockwise (clockwise), θ ₁ is positive when θ ₁ is in an area in which θ ₁ is ahead of the baseline BD. A sign (+) is added, and a negative sign (-) is added when the area is behind the base line BD, while θ ₂ is θ ₂
Is placed in a region that is later than the base line BD, a negative sign (-) is added. In a region that is ahead of the base line BD, a positive sign (+) is added. Also, when the gutter is rotated counterclockwise (counterclockwise),
The signs of θ ₁ and θ ₂ are the same as when the gutter is rotated in the clockwise direction (clockwise). For example, θ ₁ corresponds to an area where θ ₁ is set ahead of the base line BD. In some cases, a plus sign (+) is added.

[0047] Thus, each of the preferred range of theta ₂ is theta _{1 is, -75 ° ≦ θ 1 ≦ 110} ° and -75 ° ≦ θ ₂
≦ 110 °. Thus, the magnitude of the deflection angle is (θ
₁ + θ ₂ ) / 2. Accordingly, when the absolute values of θ ₁ and θ ₂ are equal to each other, the deflection angle becomes zero.

The magnitude of the deflection angle is appropriately selected from the above range depending on the shape of the gutter-like body itself and the shape of the opening, the ratio of the opening area of the upper opening to the lower opening, the use of the jet liquid, and the like. When attaching the gutter to the fixture, the fixture must not prevent the liquid from rising within the concave surface of the gutter. The rotation of the liquid sending of the plate body is the same as that of the liquid sending of the gutter-like body.

The above-mentioned narrow liquid feeder can be provided with one or a plurality of through-holes in its peripheral wall, which is more preferable. A plate can be attached at an interval from the outside of the through hole (the side close to the peripheral wall of the tank body, and so on). With this plate, the direction in which the liquid ejected from the through hole is ejected can be changed. In addition, a tube and a spray nozzle can be radially provided outside the through-hole in the narrow liquid feed. The liquid that has passed through the narrow liquid feed is ejected outward from a through hole formed in the wall of the narrow liquid feed. By selecting the size of the through hole, a desired amount of the liquid passing through the narrow liquid feed can be ejected from the through hole.

The thin liquid feed may be bendable and / or extendable. To make the thin liquid feed bendable, for example, the liquid feed may be made of a flexible material, or the thin liquid feed may be divided into a plurality of pieces laterally (substantially perpendicular to the long axis). The plurality of liquid supply fragments thus formed may be connected to each other rotatably by joints. Further, in order to make the thin liquid sending expandable and contractable, for example, the thin liquid sending inserts a plurality of liquid sending fragments which are divided into a plurality of pieces perpendicularly to the long axis, and slidably moves along the long axis. It is made possible by setting it up.

When a plurality of the thin liquid feeds are fixed to the fixture, the plurality of thin liquid feeds may be independent of the fixture or integrated with the fixture. You may. As a typical example of the gutter-like body integrated with the fixture, for example, a plate is used as a fixture, and a non-horizontal side of the plate that is a fixture is substantially a side along the side. It is bent in parallel, or the lower apex is bent along the side, and the gutter-like body is connected to the edge of the opposite side of the plate body that is not horizontal by joining the side edge of the upper surface opening A triangular or quadrangular flat plate or a curved plate that is bent outward at a small curvature at an arbitrary angle is formed at the edge of the opposite side of the plate body that is not horizontal. Gutter-like bodies and the like can be mentioned.

In this case, the plate used as the attachment is usually preferably a triangular plate or a rectangular plate such as an inverted trapezoid, a rectangle or a square, but a plate of any other shape is preferable. It does not prevent that. In the gutter-like body formed in this way, each of the upper opening and the lower opening has an asymmetric shape. The unfolded flat part of the mounting plate acts as a stirring blade. In order to prevent the fluid resistance in the plate body that is the fixture from becoming excessive, a hole is formed in the flat plate portion of the plate body,
Here, the fluid resistance can be reduced, which is preferable.

The thin liquid feed is mounted radially in parallel with the stirring shaft or with the lower opening closer to the stirring shaft than the upper opening. In the latter case, since the amount of liquid ejected from the upper opening becomes large, the thin liquid is centripetally mounted by aligning its long axis with the radial direction of the rotation plane corresponding to the mounting direction of the mounting fixture. Being attached to the tool,
Preferably, but not eccentrically mounted in a direction different from the radial direction described above. When the thin liquid feed is mounted eccentrically, the long axis of the thin liquid feed may be parallel to the radial direction on the rotation plane corresponding to the mounting direction of the fixture, or may be inclined. You may. In the case of being eccentrically inclined, it is preferable that the lower opening is eccentric so that the lower opening is advanced when the liquid supply is rotated.

The upper opening and the lower opening in the thick liquid feed are an upper opening and a lower opening, respectively.
The stirring shaft is passed through the center of each of the upper opening and the lower opening of the thick liquid sending liquid. Thus, the thick liquid feed is attached to the stirring shaft by the fixture.

The liquid feed is fixed to the fixture at a predetermined angle of inclination, or is mounted so that the angle of inclination can be adjusted arbitrarily. The latter is preferable. In the case of a thin liquid feed, the inclination angle is defined as the angle between the long axis line and the rotation plane of the thin liquid feed, and in the case of a thick liquid feed, the generatrix of the peripheral wall of the cylindrical body is used. Is defined as the angle formed by the rotation of the thick liquid and the plane of rotation. This fixation can be performed by an ordinary method such as fitting, welding, or bonding. Here, the long axis of the thin liquid sending is defined as a line connecting the center or the middle point in each of the upper opening and the lower opening of the liquid sending.

Thus, the inclination angle of the liquid feed is set to a range of greater than 0 ° to 90 °. As a result, in the narrow liquid sending, the lower opening is closer to the stirring shaft than the upper opening or the distance from the stirring shaft to the lower opening and the upper opening is substantially equal to each other. The former is preferred. In the latter case, it is preferable to close the lower opening when the thin liquid feed is a trough-like body. Also in this case, the liquid in the liquid immersion portion of the gutter is raised in the gutter. The magnitude of the tilt angle of the liquid sent depends on the shape of the liquid itself and the opening shape, the ratio of the opening area of the upper opening to the lower opening, the type of liquid, the rotation speed of the liquid sent, the head of the ejected liquid (the inner wall of the tank body). The height at which the ejected liquid reaches on the peripheral surface. The same applies hereinafter.) It is appropriately selected according to the ejected distance and the ejected amount, but usually, about 5 to 85 ° is preferable.

In order to mount the thin liquid feed on the stirring shaft so that the magnitude of the inclination angle can be adjusted, for example, the lower end of the thin liquid feed is hinged to the stirring shaft, and the vertical moving means or the horizontal direction is used. What is necessary is just to mount | wear so that an upper opening of a thin liquid sending can be moved centripetally or centrifugally along the radial direction of a rotation plane by a moving means. Here, the vertical moving means and the horizontal moving means are means for adjusting the inclination angle of the narrow liquid sending by vertically pulling up or down the upper end, which is the free end of the narrow liquid sending, and the free end of the narrow liquid sending, respectively. This is a means for adjusting the inclination angle of the narrow liquid feed by narrowing or pushing the upper part horizontally. In the above description, the movement of the upper opening of the thin liquid transfer by the vertical movement means and the movement by the horizontal movement means may be hereinafter referred to as a vertical method and a horizontal method, respectively.

Further, the length of the thin liquid feed is made longer than the radius of the plane of rotation, the lower end of the thin liquid feed is hinged to the stirring shaft, and the upper end is attached to the inner peripheral surface of the peripheral wall of the tank body. Sliding contact can be inclined. In this case, the inclination angle of the narrow liquid feed can be adjusted by changing the length of the narrow liquid feed. Further, the length of the narrow liquid feed is made longer than the winding diameter of the coiled tube installed in the tank body (the distance from the center of the wound coil to the inner circumference), and the lower end of the narrow liquid feed is used as the stirring shaft. It can be tilted by hinged and sliding the lower surface on the inner peripheral surface of the upper end of the flexible tube. In this case, by changing the position of the lower end portion (distance from the bottom of the tank body) of the thin liquid sending, the inclination angle of the thin liquid sending can be adjusted.

The fixture to which the liquid is attached is mounted on a stirring shaft, and the liquid is immersed in the lower opening below the liquid level.
By exposing the upper opening from the liquid surface and rotating the stirring shaft to rotate the liquid to be sent (this rotation may also be referred to as revolving below), the liquid in the liquid immersion part of the liquid sent is Bernoulli's Theorem (Bernoulli's theorem)
, And further, by the centrifugal force, the liquid is lifted in the liquid supply and ejected from the upper opening, and the part below the liquid surface of the liquid supply also acts as a stirring blade, and the liquid is stirred in this part .

The upper and lower openings of the thick liquid feed are respectively an upper opening and a lower opening,
The inner peripheral surface of the peripheral wall of the cylindrical body, which is a thick liquid feed, is used as a liquid flow path. In the liquid ejection method of the present invention, the rotation speed of the liquid sending, the liquid depth in the tank, the inclination angle of the liquid sending, the type of the liquid sending, the shape and thickness of the liquid sending and the type of the liquid,
It can be selected as appropriate. By revolving the liquid to be sent, the liquid level in the tank body rises on the inner peripheral surface of the peripheral wall of the tank body, and decreases around the stirring shaft, giving a funnel-like shape, and the liquid level becomes the lower opening of the liquid sent. And the liquid in the tank no longer rises in the liquid supply. In this case, the liquid level in the tank is flattened by revolving the liquid to be sent in the opposite direction.

The rotation of the stirring shaft is increased in response to the decrease in the liquid level in the tank, and the rotation of the liquid is also increased accordingly. In this manner, the liquid in the tank body is sprayed to a space above the liquid level inside the tank body and / or to a desired high place on the inner peripheral surface of the peripheral wall of the tank body.

The ejected liquid ejected from the upper opening of the liquid to be sent is (a) sprayed on the foam layer formed on the liquid surface in the tank to defoam. (B) The inner peripheral surface of the peripheral wall of the tank is sprayed to wash the inner peripheral surface of the peripheral wall of the tank. (C) Wash the heat transfer surface by spraying it on the heat transfer surface of the heating / cooling device installed in the tank body. (D) When the liquid level in the tank falls, the heat is transferred to the inner surface of the tank peripheral wall or the heat transfer surface of the heating / cooling device installed in the tank to secure the heat transfer area. I do. And / or (e) spraying in a space above the liquid level in the tank body to promote evaporation of the liquid in the tank body. Used for Said (e)
In this case, the pressure in the tank can be reduced or increased. When the pressure in the tank is reduced, the droplets sprayed in the space above the liquid surface in the tank are instantaneously boiled and evaporated, which is preferable. In addition, since the liquid sprayed on the heat transfer surface of the heating / cooling means forms a thin film on the heat transfer surface and is rapidly heated and cooled, the required time is reduced, and the energy loss is reduced accordingly. I can do it.

The size of the liquid ejection device of the present invention is not particularly limited, and may be any size. Usually, for example, a large-scale one used in a large tank in a factory manufacturing apparatus is preferable, but a small-scale one used in a laboratory used in a flask, for example, can also be used. . In the liquid ejection device of the present invention mounted in the flask, any of a thin liquid feed and a thick liquid feed can be used as the liquid. When the liquid to be sent is a thin liquid sending, the slant liquid is set at an inclination angle of 9 mm.
Close the upper end to the stirring shaft as close to 0 °, close it, pass it through the mouth of the flask and mount it in the flask, then open the narrow liquid feed and fix it at the desired tilt angle, or The upper end can be brought into sliding contact with the inner peripheral surface of the flask to have a predetermined inclination angle, and the inclination angle of the thin liquid sending in the flask can be adjusted by a vertical method. When the liquid is a thick liquid,
Usually, a separable flask is used as the flask. In the liquid jetting method of the present invention, the liquid in the tank may be a viscous liquid or a suspension having a high concentration of dispersoid.

There is no difference.

The deflection angle will be described with reference to FIG. That is, in the cross section of the opening of the gutter-shaped body 1 or the cross-section of the gutter-shaped body 1 in the plane of rotation, three points arbitrarily selected from the region to be advanced to the region to be made to follow according to the rotation direction, sequentially. Assuming that A, B, and C are the rotation axes on the same plane as the opening or cross section of the gutter-like body, these points A, B, C, and D satisfy the following conditions. .

That is, (1) the distance between B and D ≧ C to D
And (2) the angle between the line segment AB and the base line BD {the angle between the ABD and the line segment BC and the base line BD}
Assuming that the CBD is θ ₁ and θ ₂ respectively, when the gutter-shaped body is rotated clockwise (clockwise), θ ₁ is positive when θ ₁ is in an area in which θ ₁ is advanced ahead of the base line BD. A sign (+) is added, and a negative sign (-) is added when the area is behind the base line BD, while θ ₂ is θ ₂
Is placed in a region that is later than the base line BD, a negative sign (-) is added. In a region that is ahead of the base line BD, a positive sign (+) is added. Also, when the gutter is rotated counterclockwise (counterclockwise),
The signs of θ ₁ and θ ₂ are the same as when the gutter is rotated in the clockwise direction (clockwise). For example, θ ₁ corresponds to an area where θ ₁ is set ahead of the base line BD. In some cases, a plus sign (+) is added.

[0090] Thus, each of the preferred range of theta ₂ is theta _{1 is, -75 ° ≦ θ 1 ≦ 110} ° and -75 ° ≦ θ ₂
≦ 110 °. Thus, the magnitude of the deflection angle is (θ
₁ + θ ₂ ) / 2. Therefore, when the absolute values of θ ₁ and θ ₂ are equal to each other, the deflection angle is zero. The same applies to a continuous gutter.

FIG. 13 is a perspective view of a gutter-like body rotatably mounted on a stirring shaft. That is, the lower opening of the gutter 1
11 is a square rod-shaped lower support connecting the open ends 111 and 112

24 is fixed along the long axis of the gutter 1.

A lower attachment 221 and an upper attachment 222 are fixed to the stirring shaft 3 in the radial direction. Thus, the lower fixture 221 and the upper fixture 222 are both elongated rectangular plates, and the length of the lower fixture 221 is shorter than the length of the upper fixture 222. In addition, the interval between the lower mounting tool 221 and the upper mounting tool 222 is slightly longer than the vertical length of the gutter-shaped body 1 (length of the gutter-shaped body 1 × sin inclination angle). . The lower mounting tool 221 and the upper mounting tool 222 are provided with circular holes 2211 and 2221, respectively, at the tips.

The lower support bar 114 and the upper support bar 124 of the gutter 1 are connected to the circular hole 2211 of the lower fixture 221 and the upper fixture 22.
Two circular holes 2221 are inserted through the respective holes. A thumbscrew 125 is screwed to the upper support bar 124 in contact with the upper surface of the upper fixture 222. When the gutter 1 is rotated (revolved) around the stirring shaft, the gutter 1 is automatically rotated (rotated) around the long axis of the gutter 1 according to its rotation speed. )
I'm sullen.

On the other hand, the gutter-like body 1 can be fixed after being rotated so as to have a desired deflection angle. This fixation is achieved by screwing a nut (not shown) to the upper support bar 124 and tightening the nut with the thumbscrew 125 with the upper fitting 222 interposed therebetween, and / or This is performed by screwing a number of nuts (not shown), and clamping the lower mounting member 221 with these nuts. In FIG. 13, the gutter 1 can be replaced with the continuous gutter 4 shown in FIG.

FIG. 14 shows a liquid ejecting apparatus in which a pipe whose slant angle can be adjusted by a vertical method is a thin liquid sending apparatus. In FIG. 14, a, b, c, and d are a perspective view, a plan view, a front view, and a side view, respectively. However, the cross-section end surface of the stirring shaft is shown in b. That is, in this liquid ejection device, the tube 5 is used as a thin liquid sending device. The lower end of the tube 5 is hinged to the stirring shaft 3 by a hinged plate 61, while the upper end is connected to the sliding ring 31 via a connecting rod 62. The hinge plate 61 is fixed to the outer peripheral surface of the stirring shaft 3. The sliding ring 31 is slidably mounted on the stirring shaft 3. Further, the slide ring 31 is provided with a thumb screw 311 for fixing the slide ring 31 at an arbitrary position. The connecting rod 62 and the sliding ring 31 are vertical moving means.

Thus, by moving the slide ring 31 along the stirring shaft 3 in the direction perpendicular to the rotation plane, the inclination angle of the tube 5 can be adjusted. When the inclination angle of the tube 5 reaches a predetermined value, the slide ring 31 is fixed to the stirring shaft 3 by the thumb screw 311.

The liquid ejecting apparatus in which the pipe whose slant angle can be adjusted by the vertical method shown in FIG. 14 is a thin liquid sending apparatus is mounted in a tank or a flask. In the case where the tube 5 which is a thin liquid sending liquid is inclined at a desired inclination angle and fixed in the tank body or the flask, a stopper (not shown) is provided on the stirring shaft 3, and the sliding ring 31 is attached to the stopper.
