Submersible working body is intended for use in a device for grinding material, mainly pasty, containing a base in the form of a plate

I (Fig. 1), on which, by means of elastic elements 2, for example, springs, is an engine 3 connected by its shaft 4 by means of a coupling 5 to a drive shaft 6 made of inelastic or elastic material. In the first case, the drive shaft 6 is made, for example, in the form of a metal pipe, and in the second case, in the form of a rod from the material of the elastomer family or in the form of a pipe made of reinforced rubber. The implementation of the drive shaft 6 elastic allows you to exclude shock loads and the appearance of a self-oscillating mode during rotation relative to unbalanced rotating parts, which ultimately improves the reliability of the device, and also allows you to change the position of the immersed working body in the space of the tank both in height and in the diametrical plane, thereby ensuring high-quality mixing and grinding of material located in different zones of the tank.

The coupling 5 is made with the possibility of changing the angular position of the shafts 4 and 6 relative to each other, 1 the clutch 5 is made detachable to provide quick connection and separation of these shafts. As such a sleeve, a sleeve-sleeve sleeve or toroidal sleeve coupling or the like can be used.

The plate 1 rests on a container 7 filled with material intended for grinding and grinding.

Inside the tank 7 closer to the base 8 is a submersible working body.

The working body comprises an inner part 9 connected to the drive shaft 6 and an outer part 11 connected to the braking elements 10. The inner 9 and the outer

IIpartially arranged coaxially with the possibility of sliding relative to each other in the tangential direction and grinding the material during rotation of the drive shaft 6. The outer part 11 consists of several grooved elements 12, open sides facing the cylindrical working surface of the inner part 9 and arranged to slide on it with their workers edges 13 during rotation of the drive shaft 6. The grooved elements 12 are installed around the circumference with a gap 14 relative to each other and are interconnected elastic with ligature with the possibility of limited movement around the circle relative to each other and pressing the working edges 13 to the cylindrical working surface of the inner part 9. The elastic connection of the grooved elements 12 of the outer part And made in the form

rubber rings 15 (figure 2, 3 and 5), covering these elements 12 with the possibility of pressing their working edges 13 to the working cylindrical surface 16 of the inner part 9.

On the sides of the grooved elements 12 (Fig. 5) facing the rotation of the drive shaft 6, windows or cutouts 17 are made for passage of the rubbed material into the grooved element 12.

In FIG. 2 and 3 show an embodiment according to which the elements 12 are made in the form of corners. Braking elements 10 are attached to one of the sides 18 of the corners with the possibility of its location in the tangential direction to the cylindrical surface.

The braking elements 10 are blades 19, which are made of an elastic material, for example reinforced rubber or of a material of the elastomer family, and connected with the elements 12 of the outer part 11 of the working body.

A centrifugal spreader is located on the drive shaft 6, which according to the first embodiment is a disk 20 (Fig. 1), and according to the second variant (Fig. 3) - the vanes 21. The vanes 21 and the disk 20, as well as the vanes 19, are made of elastic material that allows you to change its spatial shape depending on the resistance arising from their interaction with crushed and rubbed material.

In FIG. 1 shows a variant of the arrangement of the disk 20 on the drive shaft 6 above and below the inner 9 and outer 11 parts. It is not excluded that the disk 20 is located only under parts 9 and 11, while in the first and second cases, the disk 20 is made with teeth 22 fixed on it, which, together with stirring the material, provide its grinding. The teeth 22 can be mounted on the disk 20 with the possibility of changing their position depending on the resistance of the abraded material, for which the disk 20 at the legs of the tooth 22 can be made with a recess 23 or from a material with increased flexibility.

A feature of the structural embodiment of the second embodiment (Fig. 4) is the implementation of a centrifugal sprinkler in the form of elastic radial blades 21 associated with the drive shaft 6 and located below the inner 9 and outer 11 parts.

5 direction of rotation of the non-metallic tape 24 with pre-applied

on its surface with adhesive material. At the end of the drive shaft 6 is a limiter 25 of the axial displacement of the outer part 11, preventing it from slipping from the inner part 9.

Submersible working body operates as follows.

As a result of rotation of the drive shaft 6 and the working element immersed in the working material 26, the grooved elements 12 with their edges 13 slide along the surface 16 of the inner part 9 and thereby grind the material that is introduced into the cavity of the grooved element 12 through windows or vfesa 17 located opposite rotation of the working body. In this case, the difference in the angular velocities of parts 9 and 11 is due to the interaction of the blades 19 attached to the grooved elements 12 from the outside with a sedentary mass of material 26. Thus, the incoming material 26 passes between the working surface 16 and the working edges 13, then mixed with the material located outside the grinding zone, and under the action of centrifugal forces is assigned to the periphery of the tank 7.

At the same time, the centrifugal spreader, made in the form of an elastic disk 20 with teeth 21 (Fig. 1,3) or blades 21, additionally crushes and intensively grinds the grinding material 26. The grinding process is repeated until the desired material consistency is achieved .

In order to increase the efficiency of the material grinding process, the relative angular displacement of the grinding working surface 16 and working edges 13 of the working body is automatically changed due to the presence of braking elements 10. The efficiency of the process increases when braking elements 10 are made in the form of elastic blades 19 that change their shape depending on the state of the material 26 and thereby inhibiting the outer part 11 of the working body, the greater the density and viscosity of the material.

The work of the submersible working body according to option 2 is similar to the process of grinding and mixing the material according to option 1. The centrifugal spreader, in addition to mixing and moving the material 26 through the container 7, also performs its grinding. This happens as follows. In the process of movement of the blade 19, 21 (figure 4), having elasticity, acquire, like the blade 19, a shape due to the resistance to movement of the rubbed material 26. So, in

6 the initial grinding period, when the material 26 has an increased density and

the heterogeneous blades 21 are bent along an arc and decrease in the radial direction, while the torque arising on the blades 21 increases due to a decrease in the radius of the circle of their rotation. The increase in torque contributes to the crushing of the material by separating the blades 21 in the axial direction of one part of the rubbed material 26 from the other, followed by its direction in the radial direction. In the next grinding period, when the material 26 exhibits increased fluidity compared to its initial state, the blades 21 are straightened and trap a larger amount of material 26 and mix it relative to another mass of material having a lower angular velocity of movement. Given that the centrifugal spreader operates in the exit zone of the material 26 of the grinding zone, the resistance to its angular movement is less than on the blades 19. The process of mixing and grinding of the material 26 with a centrifugal spreader, made in the form of a disk 20 with teeth 22, while the disks 20 and teeth 22 change their shape and position (figure 4), depending on the state of the material 26, and thus inhibit the outer part 11 of the working body the more, the higher the density and viscosity of the material.

The proposal meets the criterion of industrial applicability, since its manufacture is possible using existing means of production using known technologies.

The proposed design of the submersible working body of the device for grinding material is technological, simple and convenient to use. The use of the device improves the quality of grinding of the material to a finely dispersed pasty state.

The utility model can find wide application in the field of construction and in light industry in the manufacture of various dyes and in the production and processing of building and special materials, as well as in the chemical, food, perfumery and other industries.
