Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application) The present invention #''t relates to a so-called quantitative fractionation method for liquid materials, in which a certain amount of liquid material is taken out from a liquid storage container. It can be used not only when taking out a certain amount of dye from a dye container, but also when taking out a chemical solution *t in which other substances are dissolved, dispersed, and emulsified in water or an organic solvent and using it after taking it out of its storage container.

(Prior Art and its Problems) Conventional quantitative fractionation of liquid materials will be explained by taking as an example a case where necessary IIk is fractionated from a dye container during a dyeing test.

Liquid dyes include those whose main components are mostly dissolved in water, those whose main components are partially solubilized by the action of a water-soluble solubilizer, and those whose main components are partially solubilized by the action of a dispersant. Some dyes are dispersed in water due to micronization, and such liquid dyes are stocked in storage containers. During storage, the dye in the container may settle and do not exhibit a uniform liquid state. The storage containers used in the testing room are small, so shake the container by hand to thoroughly stir the inside to make it a homogeneous liquid, and then remove it with a dropper or other suction device with the lid open. Measure it out and adjust the dye bath! I am doing 1.

The method of separating dyes on-site at a dyeing factory is not much different from the method described above, except that each device is larger and a dedicated stirring device and a dedicated suction extractor are used.

However, in the case of such a one-part collection method, in order to improve the measurement accuracy of the dye collected from the storage container (hereinafter referred to as dye sample), it is necessary to Cleaning of parts) becomes mandatory 11. This maintains quantitative accuracy to a certain extent, but the dye sample collected from one storage container may be the initial one (the one taken when the dye in the storage container is nearly full). Is there a qualitative difference between the one collected at the final stage (the one collected when the remaining amount was low) and the one collected at the final stage? Uniformity of the single sample cannot be obtained, and the actual accuracy of the sample sandal cannot be sufficiently increased.

This is because there is a space inside the storage container.

Even if the dye in the storage container is homogenized by stirring, the dye adheres to and dries on the inner wall of the storage container that constitutes the space during stirring or during storage, and the agglomerated dye is mixed with use or over time. This is because the amount of liquid increases and the liquid-separated dye changes qualitatively.

(Technical 8N) The present invention provides a method for extracting a fixed amount of a liquid substance such as a dye from a storage container, in which the fractionated liquid collected from the storage container is separated regardless of the amount remaining in the storage container. The objective is to always maintain a uniform K, and for this purpose, the technical problem is to be able to separate the liquid substance without creating a space inside the liquid substance storage unit.

(Means) At the same time, the filling chamber αG is constantly pressurized in the direction of contraction, filling the filling chamber αG with a liquid substance and reducing the filling chamber αl)K! The liquid substance in the filling chamber αa is agitated and the liquid substance in the filling chamber αa is separated from the sampler (2) by connecting it in communication.

(Operation) The above technical means of the present invention operates as follows:
2) If you make t 11, this is Ki! ! A predetermined amount of liquid substance is collected from the filling chamber (1G) through which the filling chamber α
(Since I is a variable volume type and is constantly pressurized in the direction of reduction, the filling chamber (1G volumetric force is reduced by 5 depending on the amount collected. The filling chamber (IG is filled with a liquid substance) Therefore, even after the collection, the filling chamber αG is filled with the liquid substance, and no space is created in the filling chamber GG.
Because the collector (2) and the filling chamber + IG are in direct communication,
This circuit is also filled with a liquid substance, and similarly no space is created. Therefore, it is possible to prevent the liquid substance from condensing in the space itself. In addition, since the liquid substance is collected while being stirred, there will be no difference in concentration between the upper and lower parts of the filling chamber (10) or any qualitative fluctuations due to sedimentation at this point.

(Effects) Since the method of the present invention has the above configuration, it has a first-order unique effect.

Since there is no space in contact with the liquid substance in the circuit in the filling chamber αG and the collecting device (2) stage, it is possible to prevent qualitative damage due to agglomeration of the liquid substance. In addition, during collection, since no change in IR (g) occurs due to concentration differences or sedimentation in the filling chamber 0 (1), the liquid substance taken out from the collection device (2) will be slightly smaller than the remaining amount in the filling chamber (10). Therefore, if the quantitative accuracy of the amount collected by the sampler is increased, the actual sampling accuracy of the sampled liquid will be increased.

Furthermore, in the conventional method, it was necessary to clean the entire sampling device before sampling in order to improve Fi and sampling accuracy, but according to the above structure of the present invention, such cleaning is no longer necessary.

(Example) Hereinafter, an apparatus implementing the method of the present invention will be described with reference to FIGS. 1 to 4.

In the apparatus of the embodiment shown in FIG.
) is used in order to increase the growth effect when used in a test laboratory, etc., and the storage container (1) itself is of a variable volume type, and the inside thereof is used as a filling chamber αG.

For this reason, the body av of the storage container (1) is made into an elastic bellows, and the top plate (2) and the bottom plate (alpha)3 have a certain degree of rigidity. A stirrer (2) is inserted into the storage container (1) through a mouth (5) equipped with a lid αQ that can be opened and closed, and a driver (support) for driving the stirrer is inserted into the storage container ( 1) is placed.

Furthermore, a connection port αG is provided on the top plate (13), and a sampler (2) is connected to this connection port (161) via a flexible tube cy+tt. The sample container (5) placed on the container 141K is facing nine.The sampler (2) is a pump as an example of a suction/discharge device, and when the piston (2) is reciprocated, an amount of liquid corresponding to the movement area is released. can be sucked and discharged.In other words, the piston +
221 + 1 - When moved backward, the first *@ closes and the other second
When the valve @ opens, a flexible tube (
When the liquid chamber is suctioned through the piston (1) and the piston (2) is advanced, the first. The opening/closing state of the second valve is reversed, and the discharge is discharged from the discharge low.

Due to this discharge, the amount of liquid substance in the storage container (1) decreases by that amount, but since the body portion a11 is composed of an elastic bellows, the length of the body portion αD increases according to the amount of decrease. The capacity of the storage container (1) is reduced by the pressure of atmospheric pressure.

On the other hand, storage capacity! B(i) The stirrer housed in C is in contact with the driver @ through the bottom plate a31, and when this driver is driven, the stirrer oII is rotated and the liquid in the storage container (1) is rotated. The substance is stirred.

In this embodiment, the @Al17 vessel (2) is always in operation, so that the inside of the storage container (1) is always homogeneous during collection.

In addition, the diameter of the discharge pipe-1 from the first pipe (c) to the discharge port (■) is made extremely small, and the drive means (P
), and furthermore, if the drive 1t of this mutual aiding means is made variable and the drive amount can be controlled by the control device (C), the discharge amount can be set according to the set value by simply setting the discharge amount by the control device (C). A certain amount of liquid substance can be sucked and discharged.

Next, the apparatus of the second embodiment shown in FIG. 2 stores a flexible bag (1a) such as a polyethylene sheet or a plastic sheet in a rigid storage container (1), and fills the inside of the container. A chamber QG is used, and the bag is connected to the bag as a collector (2) through the first flexible tube (21a) and the joint K through the second flexible tube (21b). The downstream side of this shutoff valve becomes the discharge pipe ■ and the meter (4) K
It is placed facing the Nangle container (5).

In this embodiment, the bag (1a) is housed in the upper part of the storage container (1) so as to have an empty space αη, and this empty space αη
The pressure inside the bag (1a) is increased by setting a constant pressure above atmospheric pressure by the pressurizing means (6). Therefore.

In this case, simply by opening the shutoff valve (2a), a predetermined amount of the liquid substance in the sample container (5) can be sampled.

In addition, Fi as a stirring device, circulation pump c! Ij is adopted, and the inlet α and outlet IRU e bag (1a) of this pump are adopted.
They are connected to each other at regular intervals at their bottom. The liquid substance i in the bag (1a) constituting the filling chamber αQ is circulated through the circulation pump (2), thereby being stirred. Here, instead of the circulation pump, a stirring device using a stirrer as shown in FIG. 1 may be employed.

In all of the embodiments described above, the volume of the filling chamber was made variable by constructing the wall of the opening of the filling chamber α with a flexible material, but as shown in FIG. The movable body Ql, which becomes the earthen wall of the filling chamber αG, may be slidably inserted into the body αD with its outer periphery airtight.

Furthermore, as a special modification of the third embodiment, as shown in FIG.
It is also possible to consider a small size. This device has a motor (7) and a power source built into the piston of a syringe-shaped collector, and a drive shaft of this motor (K stirrer C1l+) is connected and exposed outside of the piston. So, the motor (
If the piston is fully pushed into the piston while driving 7), an amount of liquid substance commensurate with the amount of pushing can be collected.

Of course, the power source can be provided externally, but in this fourth embodiment, the discharge pipe c1 is located at the bottom of the cylinder (8) serving as the storage container. It has a configuration in which A is connected in series and a cap @ is attached to the tip.
By attaching it to the cap 1 at times other than when collecting, the agglomeration of the liquid substance described above will not occur.
Note that the collector/storage container of this embodiment can be used for multiple purposes other than carrying out the method of the present invention. This is because it functions as a collector as well as a storage container, and furthermore, it has a built-in stirring device.
