The invention relates to construction equipment, in particular, to installations for activating a cement slurry.

The purpose of the invention is to intensify the processes of dispersion and mixing.

The drawing shows the disnergator-mixer, section.

The disperser-mixer consists of 1 e) metric tank 1. mounted on shock absorbers 2 and having a bottom 3 with coaxially and rigidly mounted on the outside (.1Y side of the discharge pipe 4 with the cork valve 5 and on the inside of the main radiator, made in a teflon tube 6 with a niezoceramic transducer 7 enclosing it, and an additional emitter in the form of a teflon tube 8 with a piezoceramic transducer 9 connected to the inner surface of the container 1 by means of a shock absorbing pad 10. Concentrator On the shaft II (drive not shown) mounted in bearings 12 and 13 on the lid 14, the rotor 15 is shaped like a cylindrical cup with a screw thread 16 on the inner surface. On the lid 14, the nozzle 17 with the cork valve 18 is eccentrically mounted Shut-off. Hode-Hoii reinforcement for the input material.

The Lispga tor mixer works in the desired manner.

A closed cork valve 5, an open cork valve 18, an ultrasonic x-wave generator (not shown) powered by piezo-chemical converters 7 and 9, and IUI 4acoBoii drive Str. 1k rotating through the pipe 17 are fed with water-cement suspension, which the action of the rotating moment and the centrifugal force generated by the rotor 15, is pressed against the additional radiator.

When the bottom 3 is reached, the suspension accumulates and, gradually filling the container 1, picks up the screw thread 16 and moves along the main radiator.

Having reached the upper edge of the main transmitter, under the action of the own mass of the suspension, it is lowered along tube 6 along the piezoelectric transducer 7 and exposed to ultrasound. The full or partial opening of the plug valve 5 through the pipe 4 removes the cement slurry. At the same time, throughout the entire path of movement, the solid particles of the suspension are subjected to cavitation, the effects of ultrasound, mechanical erusia, impact between themselves and with the walls of the dispersant due to centrifugal force.

But when the dispersant-mixer is finished, the pump is similarly washed, after which the ultrasonic wave generator (not shown) and the drive (not shown) of the shaft II are turned off.
