A device for mixing and grinding continuous action with an elastic shell (Fig. 1) contains a working tank 1, consisting of a front end 2 and a rear end 3 between which at least one section 4 with an elastic shell 5 made of rubber, elastic or flexible polymeric or composite material. Section 4 of the working tank 1 contains an elastic shell 5, at least one rim 6 and at least one wear-resistant ring 7. The elastic shell 5 of section 4 of the working tank 1 has a cylindrical or convex axisymmetric shape and is mounted on the rims 6 using wear-resistant rings 7. The first and last, in the direction of movement of the material along the axis of rotation of the working vessel 1, sections 4 are fastened with quick-connects 8 to the front end 2 and / or rear end 3, and the intermediate sections 4 are fastened through the rims 6 to each other. The working capacity 1 is installed using the bearing units 9 on the housing 10 with the possibility of rotation. At least one diaphragm is installed between at least one pair of rims 6 of adjacent sections 4, and also between rims 6 and the rear end 3 by means of quick-detachable connections 8.

In the device for mixing and grinding continuous action with an elastic shell, diaphragms with through holes of two types can be installed simultaneously or separately.

The first type of diaphragm is a diaphragm with spokes 11 (Fig. 1, Fig. 11), consisting of two rings interconnected by spokes.

The second type of diaphragm is a diaphragm-disk 12 (Fig. 1, Fig. 3) with through holes 13, the dimensions of which in any direction along the end of the diaphragm are smaller than the smallest size of grinding media 14. If the working tank 1 contains more than one section 4 with elastic by the casing 5, the rims 6 together with the diaphragms with spokes 11 or the diaphragms-disks 12 are supported by at least a pair of support rollers 15. The support rollers 15 are mounted on the housing 10 and provided with external flanges 16 for fixing the rims 6 in the axial direction. Diaphragm disks 12 or diaphragms with spokes 11 are provided with a central hole and are mounted on a shaft 17 mounted on one side of the bearing bearings 18, on the other hand in a screw feeder 19 on bearings 20. The screw feeder 19 is mounted on bearing bearings 21 in the housing 10. The diaphragms with spokes 11 or diaphragms-disks 12 are fixed on the shaft 17 in the axial direction of the spacer sleeves 22 (Fig. 1, Fig. 2). The shaft 17 is connected via a coupling 23 to the drive 24, and the screw feeder 19 is connected via a coupling 25 to the drive 26.

The working tank 1 (Fig. 1) at the front end 2 is equipped with a loading device 27 of the processed material 28 and grinding media 14, and at the rear end 3 with a discharge device 29 of the finished product 30.

Outside of at least one section 4 of the working vessel 1, at least one roller 31 (Fig. 1, Fig. 2, Fig. 4), which contacts its outer surface with the elastic outer surface, is mounted on the housing 10 for rotation shell 5 of section 4, so that it deforms in the direction of the axis of rotation of the working container 1. At the same time, at least one roller 31 deforms the elastic shell 5 of section 4 of the working tank 1 perpendicular (Fig. 5) and / or at an angle to the axis rotation of the working tank 1 in the direction of the discharge device 29 (Fig. 1, Fig. 2, Fig. 4, Fig. 5). The axis 32 of the roller 31 is installed in the bearing assembly 33. The bearing assembly 33 is mounted on the housing 10 or on the mechanism 34 for adjusting the position of the roller 31. At least one bearing assembly 33 with the roller 31 can be mounted in elastic bearings 35 and may be equipped with a vibrator 36 The mechanism 34 for adjusting the position of the roller 31 is mounted on the housing 10 and provides a change in the position of the axis of rotation of the roller 31 in at least one of the six coordinates. The axis 32 of the roller 31 can be connected to a rotation drive 37, which is mounted on the housing 10 or on the mechanism 34 for regulating the position of the roller 31.

At least one section 4 of the working tank 1 can be provided with several rollers 31, (Fig. 1, Fig. 2, Fig. 3, Fig. 5) while their location relative to each other and the location of the roller 31 relative to the elastic shell 5 of the section 4 can be adjusted by means of a mechanism 34 for regulating the position of the roller 31. The outer surface of the roller 31 in contact with the elastic shell 5 is made of friction material in the form of a surface of revolution, for example, cylindrical (Fig. 6), toroidal (Fig. 7) or conical (Fig. . 8) forms. At least one radial protrusion 38 (Fig. 1, Fig. 2, Fig. 5) can be made on the outer surface of the roller 31 in contact with the elastic shell 5 of the section 4 of the working container 1. The radial protrusions 38 of the roller 31 are made on surfaces that provide the law of motion of the deformable section of the elastic shell 5 of the working tank 1 in the direction of the axis of rotation with at least one final acceleration jump (Fig. 9, Fig. 10, Fig. 11). For example, with a given (Fig. 9) movement schedule S of the deformable section of the elastic shell 5 of the working container 1 of the roller 31 in contact with the radial protrusion 38 in the direction perpendicular to the rotation axis of the roller 31 depending on the rotation angle ϕ of the roller 31, the speed V (Fig. 10) deformable element of the elastic shell 5 of the working tank 1 varies according to a linear law. In this case, the deformable section of the elastic shell 5 during the deformation by the radial protrusion 38 of the roller 31 will experience three soft impacts (final acceleration jumps A) at points A, B and C of the acceleration graph A in the direction perpendicular to the axis of rotation of the roller 31 depending on the rotation angle ϕ roller 31 (Fig. 11). That is, the deformable section of the elastic shell 5 will move with three final acceleration jumps when interacting with the radial protrusion 38 of the roller 31.

The inner surface of the elastic shell 5 of section 4 can be equipped with wear-resistant plates 39 (Fig. 12 Fig. 13, Fig. 14, Fig. 15), which are mounted on it with an overlap on each other, forming a coating like a "fish scale" (Fig. 14, Fig. 15). Wear-resistant plates 39 can in the plan have a round (Fig. 14), rectangular (Fig. 15) and any other shape that ensures their mutual overlap when installing an overlap. Wear-resistant plates 39 can be made flat or curved equidistantly to the inner surface of the elastic shell 5 of section 4 (Fig. 12, Fig. 13). Wear-resistant plates 39 are mounted on the inner surface through holes in the elastic shell 5 (Fig. 12) or are molded into the elastic shell 5 during its manufacture (Fig. 13). On the outer surface of the elastic shell 5 sections 4 of the working tank 1 can be made radial protrusions 40 (Fig. 12, Fig. 13). The radial protrusions 40 on the outer surface of the elastic shell 5 can be formed in the manufacture of the elastic shell 5 or formed by fasteners of wear-resistant plates 39.

The loading device 27 is made in the form of a conical funnel and is connected by a nozzle to the screw 19 (Fig. 1). The discharge device 29 is provided with at least one nozzle 41. In Fig. 1, the discharge device 29 is provided with two nozzles 41. The lower nozzle 41 is designed for unloading the finished product 30, large particles of the processed material 28 and grinding media 14. The upper nozzle 41 is equipped with a grill 42 for unloading the finished product 30 in the form of a dust-air mixture using a fan (not shown in Fig.).

The device for mixing and grinding of continuous action with an elastic rim, shown in (Fig. 1) works as follows.

Depending on the type of material being processed and the set technological processing conditions, the working capacity 1 is brought into rotation by the drive 24 and accelerated to an angular speed that provides the material being pressed 28 and the grinding media 14 against the inner surface of the elastic shell 5.

Rotation to the working capacity 1 from the drive 24 is transmitted by means of a coupling 23 connected to the shaft 17, on which diaphragms-disks 12 or diaphragms with spokes 11 rigidly connected to the rims 6 of section 4 of the working capacity 1 are mounted using spline or key connections. 15 are used in cases where the working tank 1 consists of several sections 4 and has a large length in the axial direction. Then the support rollers 15 provide additional centering of the working capacity 1 and increase its rigidity, eliminating the occurrence of low-frequency oscillations. Before the acceleration of the working capacity 1 or in the process of acceleration or steady-state operation, using the mechanism 34 for adjusting the position, at least one roller 31 deforms each elastic shell 5 of section 4. The size and direction of deformation of the elastic shell 5 of section 4 are set depending on technical properties of the processed material 28, the angular velocity of rotation of the working tank 1, as well as the position of the sections 4 relative to the front end 2 and the rear end 3 of the working tank 1.

Depending on the physicomechanical properties of the processed material 28 and the processing technology, two loading modes of the grinding media 14 into the working tank 1 are possible.

When working in the first (passage) mode, the processed material 28 and grinding bodies 14 are simultaneously loaded into the rotating working container 1 through the loading device 27. The processed material 28 and grinding bodies 14 are loaded into a conical funnel with the nozzle of the loading device 27 and with the help of a screw 19 connected through the coupling 25 with the drive 26 are fed into the first section 4 of the working tank 1. In this mode of operation, the diaphragm-disks 12 are not installed (Fig. 2), providing free flow of the processed material 28 and grinding media 14 between sections 4 in eg occurrence discharge device 29. The rotation of the working tank 1 in this case is provided by motor 24 through the aperture with spokes 11 (FIG. 2).

In the second processing mode (chamber) (Fig. 1), the grinding bodies 14 of the required size and shape are preliminarily loaded before each section 4 separately, and the diaphragm disks 12 are mounted on the shaft 17. The size and shape of the grinding bodies 14 of each section 4 may vary and depend on the size of the processed material 28, located in section 4 (chamber). The processed material 28 in this case is loaded into a rotating working container 1 through the loading device 27.

Under both treatment conditions, the processed material 28 loaded into the rotating working container 1 and grinding media 14 under the action of centrifugal forces move along the inner surface of the elastic shell 5 of the working container 1 and, due to friction forces, are accelerated to the angular velocity of rotation of the working container 1. The pressure value of the processed material 28 and grinding media 14 on the elastic shell 5 depends on the radius of the working tank 1, the angular velocity of rotation and the thickness of the layer of the processed material 28 and grinding media 14. In the process of joint movement I processed material 28 and grinding bodies 14 with an elastic shell 5, the processed material 28 is compacted and crushed due to shear deformations that occur in the mixture flow of the processed material 28 and grinding bodies 14. During the deformation of the elastic shell 5 with at least one roll 31, the thread the mixture of the processed material 28 and / or grinding bodies 14 located on the deformable section is torn off from the inner surface of the elastic shell 5 of section 4 and moves in the direction of the axis of rotation of the working container 1 perpendicularly or at an angle to the axis of rotation, towards the discharge device 29. The direction and flow rate of the mixture of the processed material 28 and / or grinding bodies 14 when leaving the deformed section of the elastic shell 5 of section 4 depend on the size, method and form of deformation of this section. Thus, after passing through the deformed section of the elastic shell 5, the flow of the mixture of the processed material 28 and grinding bodies 14 is detached from the inner surface of the elastic shell 5 and falls on the inner surface of the elastic shell 5 (Fig. 1, Fig. 2), covered with wear-resistant plates 39 (Fig . 14, Fig. 15). The trajectory of the processed material 28 and grinding media 14 inside the working tank 1 in cross section is shown in (Fig. 4). When the flow of the mixture of the processed material 28 and / or grinding bodies 14 falls onto the inner surface of the elastic shell 5 of the working tank 1, additional mixing and grinding of the processed material 28 occurs upon impact with wear-resistant plates 39 (Fig. 12, Fig. 13) covering the inner surface of the elastic shells 5. In addition, while moving along the deformed section of the elastic shell 5, intense shear deformations occur in the mixture flow of the processed material 28 and grinding bodies 14, which ensure additional mixing and grinding of the processed material 28. Repeated cycles of movement of the processed material 28 and grinding media 14 in the working tank 1 leads to uniform mixing of the ingredients in the case of mixtures or intensive grinding of the processed material 28 due to multiple shear deformations (abrasion) occurring in the stream a mixture of the processed material 28 and grinding media 14, and the impact of grinding media 14. The movement of the processed material 28 and grinding media 14 in The direction of the discharge device 29 is due to the fact that at least one roller 31 in each section 4 deforms the elastic shroud 5 at an angle to the axis of rotation of the working tank 1 towards the rear end 3 and discharge device 29 (FIG. 5). The speed of movement of the grinding media 14 and the processed material 28 inside the working container 1 in the direction of the discharge device 29 is controlled by the mechanism 34 for regulating the position of the roller 31 by changing the inclination of its rotation axis to the axis of rotation of the working container 1. Similarly, the mixing and grinding process is repeated in each section 4 working capacity 1. When installed inside the working capacity of the diaphragm disks 12, additional grinding and mixing of the processed material 28 occurs due to abrasion and impact damage eniya in contact with the flow of the processed material mixture 28 and the grinding bodies 14 to the surface of diaphragm disc 12 (FIG. 1). The diaphragm-disks 12 installed between the sections 4 of the working capacity 1 prevent the movement of the grinding media 14 from one section 4 to another section. Since the size of the through holes in the diaphragm disk 12 in any direction is smaller than the size of the grinding bodies 14, the processed material 28 moves from one section 4 to another, pouring through the holes in the diaphragm disk 12. The fractions of the processed material 28 ground to a predetermined grinding fineness can move along the axis of rotation of the working tank 1 in the direction of the discharge device 29 in the form of a dusty air mixture due to the vacuum created in the working tank 1 by a suction fan (not shown in Fig.). In the first (passage) mode, the dust-air mixture of the processed material 28 freely moves along the axis of rotation of the working container 1, and in the second (chamber) processing mode, the dust-air mixture with the processed material 28 moves between sections 4 of the working container 1 through the openings in the diaphragm disk 12. Speed the movement of the crushed processed material 28 and the maximum size of the removed crushed particles in this case are determined and controlled by the capacity of the suction fan.

In order to increase the intensity of shear deformations, increase the intensity of the shock effects of grinding media 14, as well as to more completely separate the processed material 28 from the elastic shell 5 to prevent overgrinding, the deformation of the elastic shell 5 by rollers 31 can be carried out according to special laws that ensure the creation of shock (spasmodic) accelerations in the flow of the mixture of the processed material 28 and grinding media 14 (Fig. 11). In the device for continuous mixing and grinding of continuous action with an elastic shell, the impact-deformation effect on the elastic shell 5 can be realized in three ways.

In the first case, the shock-deforming effect occurs as a result of the interaction of the elastic shell 5 of section 4 of the working vessel 1 with radial protrusions 38 (Fig. 2, Fig. 5) made on the external contacting surface of the roller 31. Radial protrusions 38 are made along the profile providing shock impact on the elastic rim 5. For example, the radial protrusion 38 can deform the elastic rim 5 according to the law, which provides three final jumps of acceleration A (Fig. 11). The rotating roller 31 with radial protrusions 38 periodically deforms the surface of the elastic shell 5, creating a shock deformation of the elastic shell 5. The energy of the shock deformation of the elastic shell 5 is transmitted through wear plates 39 to the processed material 28 and grinding media 14 located in the zone of impact deformation. Due to the impact of the inner surface of the elastic shell 5, the processed material 28 and grinding bodies 14 are torn away from it, move inside the working container 1 and fall on the inner surface of the elastic shell 5, where due to the friction forces and the action of centrifugal forces they continue to move together with the inner surface of the elastic shells 5. After which the process is repeated.

In the second case, the shock-deforming effect on the elastic shell 5 of the working tank 1 can be realized due to the vibrational effect of the roller 31 on the elastic shell 5. The vibration of the smooth or equipped with radial protrusions 38 roller 31, mounted in the elastic supports 35 is carried out by a vibrator 36 (Fig. 1 ) All the rollers 31 that are mounted on the elastic supports 35 can be provided with a vibrodrive 36. In addition, structurally the vibrodrive 36 can be connected to the roller position regulation mechanism 34. The shape of the vibratory displacements 36 set by the vibrodrive 36 should also provide impacts on the outer surface of the elastic shell 5, in contact with the outer surface of the roller 31.

In the third case, the shock-deforming effect on the elastic shell 5 of the working tank 1 can be realized by forming special protrusions 40 on the outer surface of the elastic shell 5 (Fig. 12, Fig. 13). The protrusions 40, interacting with a smooth or provided with radial protrusions 38 of the contact surface of the roller 31, also provide impact on the processed material 28 and grinding bodies 14 located in the deformation zone of the elastic shell 5.

All three methods of shock-deforming effects can be structurally implemented both on one section 4 of the working tank 1, and distributed in different sections 4 along the axis of rotation of the working tank 1.

When shock-deforming effects on the elastic shell 5, the processed material 28 is subjected to additional impact-abrasion. In this case, the mixing of the ingredients of the processed material 28 occurs more intensively due to the difference in the perception of the impact by particles of different sizes and masses and more intensive grinding due to the impact on the processed material 28, grinding media 14 and large particles of the processed material 28. In the absence of shock-deformation impact grinding of the processed material 28 occurs mainly due to the crushing and abrasion of the grinding media 14 on the processed material 28 p and its movement along the concave surface of the elastic shell 5, as well as when moving along the deformed section of the surface of the elastic shell 5. And in the case of shock-deforming effects on the elastic shell 5, additional grinding of the processed material 28 occurs in the impact zone, as well as in the impact zone of the processed material 28 and grinding bodies 14 with the inner surface of the elastic shell 5, covered with wear-resistant plates 39 and with a diaphragm-disk 12 by increasing the speed of impact. Wear-resistant plates 39, in addition to increasing the level of intensity of impact on the processed material 28, do not allow forming on the inner surface of the elastic shell 5 of section 4 of the layer of over-crushed material 28. Wear-resistant plates 39 (Fig. 12, Fig. 13) are mounted on the inner surface of the elastic shell 5 section 4 with the provision of their mutual overlapping by the type of "fish scale" (Fig. 14, Fig. 15). Relative movement in the deformation zone of the overlapping wear-resistant plates 39 overlapped with each other eliminates overgrinding, since the processed material 28 located on them is cleaned and removed by the edges of the adjacent wear-resistant plates 39, as well as by the mixture flow of the processed material 28 and grinding media 14.

The crushed processed material 28, and in the case of the first (through) operation mode, and the grinding media 14, gradually move along the axis of rotation of the working vessel 1 towards the discharge device 29, where the finished product 30 is unloaded through the nozzles 41.

The size of the removed particles of the processed material 28 can be controlled by the capacity of the suction fan and the level created by the vacuum in the working vessel 1. If necessary, the finished product 30 is classified into fractions, and the under-ground processed material 28 is fed back to the continuous mixing and grinding device with an elastic shell.

If the diaphragm disks 12 are installed in the working tank 1, then the finished product 30 without grinding media 14 enters the unloading device 29. At the same time, through the upper pipe 41 (Fig. 1), the finished product 30 is removed in the form of an air-dust mixture using a suction fan, and larger particles of the finished product 30 or the finished mixture is removed through the lower pipe 41. The grill 42 in the pipe 41 separates larger particles of the finished product 30 from the dust-air mixture stream, which are then discharged through the lower pipe 41.

Thus, the proposed device for mixing and grinding continuously with an elastic shell can increase the productivity of the grinding and mixing process, reduce the duration of the processing cycle and increase the level of dispersion (fineness of grinding) of the crushed material and prevent its overgrinding.
