Description

The claimed invention relates to a device for mixing and grinding powdered, grain or lump materials and can be used for the preparation of powders and bulk mixtures in the construction, chemical, food and other industries, as well as in agriculture.

An analogue of the claimed invention is a device for continuous mixing and grinding mixtures of bulk materials.

The device contains a rotating cylindrical working capacity mounted on bearings, a rotor with blades mounted on it using brackets made in the form of disks with through holes. Between the rim of the disk and the inner surface of the working capacity there is a gap the size of which is smaller than the smallest size of the grinding media in contact with the ends of the disk. The smallest size of the grooves and / or holes in the blades and holes in the disks is smaller than the smallest size of the grinding bodies in contact with the ends of the disk. The blades are equipped with shaped protrusions, and grooves are made on the disks, the shape of which corresponds to the shape of the shaped protrusions. The blades are mounted on the disks with the possibility of regulating their position relative to the disks. (Patent for invention No. 2576465, B22C 5/04, d.p. 10.03.2016, bull. No. 7).

A device for mixing and grinding continuous action with a 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 and / or flexible shell 5 made of rubber is installed, flexible or flexible polymeric or composite material. Section 4 of the working tank 1 contains an elastic and / or flexible shell 5, at least one rim 6 and at least one wear ring 7. The elastic and / or flexible shell 5 of section 4 of the working tank 1 has a cylindrical or convex axisymmetric shape and is mounted on 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 attached through ode 6 together. The working capacity 1 is installed using the bearing units 9 on the housing 10 with the possibility of rotation. A diaphragm is installed between at least one pair of rims 6 of adjacent sections 4, as well as between rims 6 and the rear end 3 by means of quick couplings 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 and / or flexible shell 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 are provided with external collars 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 is contacted by its outer surface with an outer surface flexible and / or flexible, is mounted on the housing 10 the shell 5 of section 4, so that it deforms in the direction of the axis of rotation of the working tank 1. At least one roller 31 deforms the elastic and / or flexible shell 5 of section 4 of the working tank 1 perpendicularly (Fig. 5) and / or at an angle to the axis of rotation of the working tank 1 in the direction of the device unloading and 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 installed in the elastic bearings 35 and can 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 is relatively elastic and / or flexible the shell 5 of section 4 can be adjusted using the mechanism 34 for adjusting the position of the roller 31. The outer surface of the roller 31 in contact with the elastic and / or flexible 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 and / or flexible rim 5 of section 4 of the working container 1. The radial protrusions 38 of the roller 31 are made on surfaces providing the law of motion of the deformable section of the elastic and / or flexible 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, for a given (Fig. 9) movement schedule of the deformable section of the elastic and / or flexible shell 5 of the working container 1 of the roller 31 in contact with the radial protrusion 38 in the direction perpendicular to the axis of rotation of the roller 31 depending on the rotation angle ϕ of the roller 31, the speed V ( Fig. 10) of the deformable element of the elastic and / or flexible shell 5 of the working tank 1 varies linearly. In this case, the deformable section of the elastic and / or flexible 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 from the angle ϕ of rotation of the roller 31 (Fig. 11). That is, the deformable portion of the elastic and / or flexible 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 and / or flexible shell 5 of section 4 can be equipped with wear-resistant plates 39 (Fig. 12 Fig. 13, Fig. 14, Fig. 15), which are fixed on it with an overlap on each other, forming a coating like "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 on the inner surface of the elastic and / or flexible shell 5 of section 4 (Fig. 12, Fig. 13). Wear-resistant plates 39 are mounted on the inner surface through holes in the elastic and / or flexible rim 5 (Fig. 12) or are molded into an elastic and / or flexible rim 5 during its manufacture (Fig. 13). On the outer surface of the elastic and / or flexible shell 5 of the sections 4 of the working tank 1 can be made radial protrusions 40 (Fig. 12, Fig. 13). Radial protrusions 40 on the outer surface of the elastic and / or flexible shell 5 may be formed in the manufacture of the elastic and / or flexible shell 5 or formed by fasteners of wear 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 unloading device 29 is equipped 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 with a fan (not shown )

The device for mixing and grinding continuous action with the shell 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 rotated by the drive 24 and accelerated to an angular velocity that provides the material being pressed 28 and the grinding media 14 against the inner surface of the elastic and / or flexible 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 tank 1 or in the process of its acceleration or steady state operation, with the help of the mechanism 34 for adjusting the position of at least one roller 31, each elastic and / or flexible shell 5 of the section 4 is deformed. The size and direction of deformation of the elastic and / or flexible shell 5 sections 4 are set depending on the 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 processing 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 and / or flexible shell 5 of the working container 1 and are accelerated to the angular velocity of rotation of the working container 1 due to friction forces. the pressure of the processed material 28 and grinding bodies 14 on the elastic and / or flexible shell 5 depends on the radius of the working vessel 1, the angular velocity of rotation and the thickness of the layer of the processed material 28 and grinding bodies 14. Percent In the process of joint movement of the processed material 28 and grinding bodies 14 with an elastic and / or flexible shell 5, the processed material 28 is compacted and crushed due to shear deformations arising in the mixture flow of the processed material 28 and grinding bodies 14. During deformation of the elastic and / or flexible shell 5 by at least one roller 31, the flow of the mixture of the processed material 28 and / or grinding bodies 14 located on the deformable section is detached from the inner surface of the elastic and / or flexible shell 5 of section 4 and moves in the direction of the axis of rotation of the working tank 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 and / or flexible shell 5 of section 4 depend on the size, method and form of deformation of this section. Thus, after the passage of the deformed section of the elastic and / or flexible 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 and / or flexible shell 5 and falls on the inner surface of the elastic and / or flexible shell 5 (Fig. 1 , Fig. 2), coated 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 and / or flexible shell 5 of the working vessel 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 and / or flexible shell 5. In addition, during movement along the deformed section of the elastic and / or flexible shell 5 in the flow of the mixture of the processed material 28 and grinding bodies 14, intense shear deformations, providing 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 preparing mixtures or intensive grinding of the processed material 28 due to multiple shear deformations (abrasion) occurring in the flow of the mixture of the processed material 28 and the grinding media 14, and the impact of the grinding media 14. Moving the processing material 28 and grinding bodies 14 in the direction of the discharge device 29 due to the fact that at least one roller 31 in each section 4 deforms the elastic and / or flexible shell 5 at an angle to the axis of rotation of the working vessel 1 in the direction of the rear end 3 and discharge devices 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 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 impacts of grinding media 14, as well as to more completely separate the processed material 28 from the elastic and / or flexible shell 5 in order to prevent overgrinding, the elastic and / or flexible shell 5 can be deformed by rollers 31 using special laws providing 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 and / or flexible shell 5 can be realized in three ways.

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

In the second case, the shock-deforming effect on the elastic and / or flexible shell 5 of the working tank 1 can be realized due to the vibration effect of the roller 31 on the elastic and / or flexible shell 5. The vibration of the smooth or equipped with radial protrusions 38 roller 31, mounted in elastic supports 35 is carried out by a vibrodrive 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 that are elastic and / or flexible shell 5 in contact with the outer surface of the roller 31.

In the third case, the impact-deformation effect on the elastic and / or flexible shell 5 of the working tank 1 can be realized by forming special protrusions 40 on the outer surface of the elastic and / or flexible shell 5 (Fig. 12, Fig. 13). The protrusions 40, interacting with a smooth or provided with radial protrusions 38 contact surface of the roller 31, also provide impact on the processed material 28 and grinding media 14 located in the deformation zone of the elastic and / or flexible 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 impact on the elastic and / or flexible 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 and / or flexible shell 5, as well as when moving along the deformed surface of the surface of the elastic and / or flexible shell 5. And in the case of shock-deforming effects on the elastic and / or flexible shell 5, additional grinding of the processed material 28 in the impact zone, as well as in the impact zone of the processed material 28 and grinding media 14 with the inner surface of the elastic and / or flexible shell 5, covered with wear-resistant plates 39 and with a diaphragm-disk 12 increasing impact velocity. Wear-resistant plates 39, in addition to increasing the level of intensity of impact on the processed material 28, do not allow the elastic and / or flexible shell 5 of section 4 of the layer of over-ground processed material 28 to form on the inner surface. Wear-resistant plates 39 (Fig. 12, Fig. 13) are mounted on the inner the surface of the elastic and / or flexible shell 5 of 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 of continuous action with the 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.
