Abstract

This invention relates to biotechnology and may find wide application in various areas of biotechnology for fine and ultrafine grinding of materials. The purpose of the invention of the retention is to increase the reliability of the disintegrator. The disintegrator contains a chamber 1 with nozzles 2 and 3 filled with grinding bodies, a mixing rotor 4 consisting of a shaft 5 and disks 6 fixed on it parallel to it, a slotted separator 7 with slots 8 mounted between the disks and rigidly connected with them to form a cavity 9 for disintegrator. The rotor 4 is provided with bushings 10 installed between the discs for passing the suspension through the cavity 9. The shaft 5 is hollow to form channel 11 and communicates with the cavity 9 and nozzle 3. The inlet pipe 2 is connected by a pipe 12 with a pressure generating source 13 of the injected suspension. As a result of placing the separator between the discs, disintegration products do not clog up the separator slots. 1 Il. With P

FIELD OF THE INVENTION The invention relates to biotechnology and can be widely used in the microbiological industry as well as in various fields of biotechnology, in folk farms using methods of fine and ultrafine grinding of materials.

The purpose of the invention is to increase the reliability of work.

The drawing schematically shows the proposed disintegrator, a longitudinal section.

The disintegrator contains a chamber 1 filled with grinding bodies (conventionally not shown) chamber 1 with pipes 2 and 3 a mixing rotor 4 consisting of a shaft 5 and disks 6 fixed on it parallel to it, a slotted separator 7 with gaps 8 mounted between the disks and rigidly associated with them to form a disintegrating cavity 9. The rotor 4 is provided with bushings 10 installed between the discs for passing the suspension through the cavity 9. The shaft 5 is hollow to form a channel 11 and communicates with the cavity 9 and the nozzle 3. The inlet 2 is connected by a pipe 12 to a source 13 for generating pressure of the supplied suspension.

Disintegrator works as follows.

When the electric drive is turned on, the rotation is transmitted to the shaft 5 of the rotor 4, which, rotating, actively mixes the grinding bodies.

The suspension of microorganisms is supplied under pressure by the source 13 through conduit 12 and through the openings of the sleeves 10 into the mixing zone of the grinding bodies in the chamber 1.

When the grinding media interacts, the suspension of microorganisms disintegrates and disintegrates. through the slots B of the separator 7, the channel 11 of the shaft 5. and the nozzle 3 is led out. The pressure of the suspension at the inlet should correspond to the expression Pg P, where, the pressure generated inside the rotor by centrifugal forces is determined by the formula

W - rotation frequency of the rotor. A feature of the disintegrator's operation is that the separator 7 rotating together with the rotor 4 discards all the grinding bodies from itself to the periphery of the chamber 1, preventing them from entering the separator slots 8, while into the cavity 9 of the rotor and from there through pipe 3 to the outside.

Due to this spatial placement of the separator on the rotating rotor, disintegration products, destroyed and substandard grinding bodies, do not plug the separator slots. This allows you to significantly increase the time of the disintegrator to the next prophylaxis, increase the reliability of its work and productivity, reduce the time and cost of its maintenance, reduce the requirements for dimensional condition of grinding media.
