RU72155U1 - WET GRINDING DISINTEGRATOR - Google Patents

Abstract

A wet grinding disintegrator comprising a housing forming a grinding chamber with loading and unloading windows, with rotors with shock rods and drives installed inside it, characterized in that the grinding chamber is equipped with rotating brush cleaning devices located perpendicular to the axis of the rotors, while the cleaning devices equipped with their own drives that do not have a mechanical connection with the rotor drives.

Description

The utility model relates to devices for grinding, activating and mixing various materials with rotating impact elements of the rod type and can be used in the manufacture of building materials, metallurgical and chemical industries, agriculture, etc.

A known disintegrator containing a housing in which rotors with percussion elements and electric motors are located, is used to grind dry materials, in which particles of the processed material, passing through the rows of percussion elements and discarded from the surface of the rotors, hit the walls of the grinding chamber and are carried outside the discharge chamber window. (See A.S. No.317420, IPC В02С 13/22, publ. 1972).

The disadvantage of this disintegrator is the increased requirements for the maximum allowable humidity of the processed materials, which does not allow the use of this equipment for grinding wet

materials that are capable of sticking to the walls of the grinding chamber, forming arches, densified areas, up to the complete filling of the internal volume of the grinding chamber and jamming of the rotors of the disintegrator.

The closest in technical essence and the achieved result to the proposed disintegrator is a device for grinding solid materials in a liquid (See RU No. 2169617, IPC V02C 13/22, published on June 27, 2001). The device comprises a housing, disk-shaped working bodies rotating in opposite directions, rectangular shock elements, accelerating blades located on the periphery of the working body. The invention allows the grinding of solid material in a liquid, followed by their separation.

The disadvantage of this disintegrator is the inability to work with materials that adhere to the walls of the working chamber.

The technical task of the utility model is to increase the reliability of the disintegrator when processing wet materials, pastes, solutions and suspensions, preventing clogging of the grinding chamber with the processed material and jamming of the rotors.

The stated technical problem is ensured by the fact that in a wet grinding disintegrator containing a casing forming a grinding chamber with loading and unloading windows, with rotors with shock rods and drives installed inside it, the grinding chamber is equipped with rotating brush-type cleaning devices located perpendicular to the axis of the rotors, at the same time, the cleaning devices are equipped with their own drives that do not have a mechanical connection with the rotor drives.

Due to the fact that the grinding chamber is equipped with rotating brush-type cleaning devices located perpendicular to the axis of the rotors, wet materials do not stick to the walls of the grinding chamber and fill its internal volume, which allows

avoid jamming of the rotors of the disintegrator, that is, it provides the possibility of the disintegrator working when processing wet materials, pastes, solutions and suspensions.

The fact that the cleaning devices are equipped with their own drives, which do not have a mechanical connection with the rotor drives, allows for other types of communication, for example, electrical, which increases the reliability of the disintegrator.

The essence of the utility model is illustrated in the drawing.

Figure 1 presents a General view of the disintegrator wet grinding with the removed front wall of the housing;

Figure 2 presents a section aa of the disintegrator of wet grinding.

The wet grinding disintegrator consists of a housing 1, which forms a grinding chamber 2 with loading 3 and unloading 4 windows. In the grinding chamber 2 there are rotors 5 with shock rods 6. The rotors 5 are driven by the drives 7 of the disintegrator. Rotary cleaning devices 8 brush type equipped with their own drives 9.

The work of the disintegrator wet grinding is as follows. Wet material, paste, solution or suspension to be crushed in a disintegrator, flows continuously through a loading window 3 into the central part of the rotors 5. Under the action of centrifugal forces, the particles of the processed material move to the periphery of the rotors 5 with shock rods 6 mounted by concentric circles on the working surface rotors 5. Particles of the crushed material, leaving the rotor 5 of the disintegrator, hit the brushes of the cleaning devices 8 and stick to them. The layers adhered to the brushes 8 of the material are scraped off, contacting the walls of the housing 1 during rotation of the cleaning devices 8, and are removed from the grinding chamber 2 through the discharge window 4. Thus, sticking of the crushed material to the walls of the grinding chamber 2 of the disintegrator is completely eliminated.

The use of a wet grinding disintegrator eliminates the mandatory drying of the processed materials and their dusting during grinding, increases the reliability of work by preventing the grinding chamber from clogging with the processed material and jamming of the rotors, reduces the total cost of obtaining finely dispersed products, pastes, solutions and suspensions of various solids content, thereby expanding scope of this equipment.
