Description

The invention relates to devices for processing the material, intended for grinding, grinding and mixing upon receipt of finely dispersed pasty substances, in particular paints and varnishes, putty and primers, used for applying, in particular, to the surface of wood, metal, concrete, brick, wood fiber and wood chip materials.

The closest in technical essence and the achieved result to the proposed solution "Submersible working body" is the invention for "Submersible working body of the device for grinding material" according to the patent of the Russian Federation No. 2064340, MKI V02C 19/20, publ. 07/27/1996.

According to a known solution, the submersible working element of the device for grinding material contains a grinder associated with the drive shaft. In addition, the working body has an inner part connected to the drive shaft and an outer part connected with the braking elements, the said parts are located relative to each other coaxially with the possibility of grinding the material.

It is also known a solution according to the patent of the Russian Federation No. 8910, publ. 01/16/1999, according to which the submersible working body of the device for grinding material has a grinder associated with the drive shaft and made in the form of a disk of elastic material with teeth located on its surface. The specified decision was taken as the closest analogue.

The disadvantages of the closest analogue, as well as the above solution, is the low efficiency of mixing and grinding of the material, due to the design of the grinder.

The task to which the proposed technical solution is directed is to eliminate these drawbacks and increase the efficiency of grinding and mixing the material. The technical result consists in providing during the rotation of the working body the formation of not only circular and axial movements of the crushed material, but also its relative movement relative to the spiral-shaped pointed protrusions made on the side surface of the teeth.

To achieve the technical result, the submersible working element for the device for mixing and grinding the material contains a grinder connected to the drive shaft, made in the form of a disk of elastic material with teeth located on its surface, while said teeth are made in the form of a rod with a sharp thread located on the side surfaces in a spiral with the possibility of the formation of vortices.

There are other possible embodiments of the utility model, according to which it is necessary that:

- each tooth would be made screw-shaped with the possibility of forming vortices relative to the longitudinal axis of the rod in the direction from the said disk during its rotation.

- as teeth, self-tapping screws or screws fixed to the aforementioned disk would be used.

- it would be equipped with at least one additional chopper, also made in the form of a disk of elastic material with teeth located.

- the elastic material would be an elastomer.

- said teeth would be located at least on one of the sides of the disk.

- said teeth would be located on the side surface of at least one disk.

These signs are essential and interconnected causally with the formation of a combination of essential signs necessary and sufficient to achieve the specified technical result, namely, increasing the efficiency of grinding and mixing of the material and to obtain finely dispersed paste-like substances, in particular paints, putty and primers used, in particular, for applying to the surface of wood, metal, concrete, brick, wood fiber and wood chip materials.

In FIG. 1 shows a submersible working body of the device.

In FIG. 2 - fragment of the mounting of the rod on the disk.

The utility model is illustrated by a specific implementation example, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving this set of features of a technical result.

Submersible working body is intended for use in devices for mixing and grinding material, mainly to a paste-like state. Said device comprises a base in the form of a base plate 1 (Fig. 1), on which a motor 3 is located by means of elastic elements 2, connected by its shaft 4 by means of a coupling 5 to a drive shaft 6 made of elastic or inelastic material. In the first case, the drive shaft 6 is made, for example, in the form of a rod from a material of the elastomer family or in the form of a pipe made of reinforced rubber, and in the second case, it is made, for example, in the form of a metal pipe. The implementation of the drive shaft 6 elastic allows you to exclude the appearance of a self-oscillating mode during rotation relative to unbalanced rotating parts, which ultimately improves the reliability of the device, and also this solution 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, in addition, the coupling 5 is made detachable to provide quick connection and separation of these shafts.

The base 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 contains a grinder connected to the drive shaft, which is made in the form of a disk 9 of elastic material with teeth 10 located on its surface.

In order to increase the efficiency of grinding and mixing the material, the teeth 10 are screw-shaped with the possibility of turbulence formation.

In the best embodiment, each tooth 10 is made in the form of a rod 11 with a sharp thread 12 located on the lateral surface in a spiral with the possibility of forming turbulences relative to the longitudinal axis of the rod in the direction from the said disk 9 during its rotation. In one embodiment, hardened self-tapping screws or screws screwed into the disk 9 are used as teeth.

To increase productivity, the teeth 10 are located on at least one of the end sides 13 of the disks 9 and / or on their side surface.

In order to increase productivity in the case of mixing the material with a high degree of heterogeneity, it is advisable to place the disks 9 at different angles "a" to the axis of the drive shaft 6 (Fig. 1).

The working body of the device for grinding material works as follows.

When you turn on the engine 3 as a result of rotation of the drive shaft 6 and immersed in the crushed material of the working body, the disk 9 with the teeth 10 in the form of self-tapping screws comes into interaction with the mixed material. Given that in the initial period the fluidity of the material is low, the elastic disk 9 does not occupy a position in one plane, but, being deformed, forms a helical shape due to the resistance of the material. The helical shape of the disk 9 with the teeth 10 defines a definite directional movement of the material, close to the direction along the axis of the drive shaft 6 in one direction or another (similar to the work of the propeller), increasing the intensity of mixing. At the same time, sharp-pointed teeth 10 mounted on the disk 9 crush and intensively grind the material being mixed due to the presence of sharp threads and the formation of a vortex motion of the material being processed, i.e. In the process of mixing and grinding, a multi-vector movement of this material is carried out.

Thus, the entire mass of material in the container 7 is mixed and falls under the action of the teeth 10 of the disk 9. The process of mixing and grinding of the material is carried out until a finely dispersed paste-like material is obtained.

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 be widely used in the field of construction and 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.
