Description

 The invention relates to the field of construction equipment, in particular to apparatus for dispersing and mixing mineral substances used in the building materials industry.

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

The drawing shows a dispersant mixer, section.

 The disperser-mixer contains a hermetic container 1 in the form of a cylinder, which is installed on the shock absorbers 5 by means of a bottom 2 with an outlet pipe 3 equipped with cork edge Hoiyi 4, and inside it on an arm made in the form of an annular support 6 by means of an annular cushioning gasket 7 and a similar annular gasket 8 mounted between the annular gaskets 9, rigidly and coaxially mounted on the inner side of the cover 10c with a centrally mounted bearing support 11 of the hollow central drive shaft 12 with a pulley 13, growing around a rigidly mounted loading nozzle 14 with a plug valve 15 on bearings 16, the lower end of which is provided with holes 17 located at the level of the rotor 18 with ribs 19, a membrane 20 is installed, made with a toroidal surface in the upper part and a reflector 21 assembled from sections mounted on the inner side of the membrane 20, which is made with holes 22 around the perimeter of a rigidly fixed magnetostrictive

ABOUT

from so ate

a transducer 23 on the lower outer side of its horizontal base.

Dispersant mixer works as follows.

When the cork valve 4 is closed, the magnetostrictive transducer 23 is turned on and the hollow drive shaft 12 is driven (not shown) through the nozzle 14, by fully and partially opening the cork valve 15, a suspension is fed, which through the holes 17 enters the rotating rotor 18, where it is evenly distributed ribs 19 in the horizontal and vertical planes and under the action of centrifugal force is applied to the reflector 21. In this case, the suspension particles undergo mechanical erosion, collision of these particles, friction between the particles and the surface new reflector. At the same time, the suspension is affected by an ultrasonic field, concentrated by the torus part of the surface of the membrane 20 in its central part, which causes cavitation processes, which are the main factors for the dispersion of solid particles and mixing of grinding products with the liquid phase. A significant part of the suspension, after moving along the reflector 21, again enters the rotor 18 and the processes of dispersion and mixing are repeated. After the suspension is lowered into the zone between the rotor 18 and the upper part of the membrane 20 in its central Zone, it is exposed to an ultrasonic field amplified by the reflection of waves from the surface of the rotor 18 and caused by cavitation in the presence of turbulent motion. The effect of dispersing and mixing enhances the presence of centrifugal force. Through the openings 22, the suspension enters the bottom 2, where, cooling the magnetostrictor, it is subjected to ultrasonic action from the side of the central part of the membrane 20 and the accompanying Aavitation.

Holes 22 act as hydrodynamic emitters, thereby enhancing the dispersion and mixing process.

By full and partial opening

the slurry valve 4, which has undergone dispersion and mixing processes through nozzle 3, is removed.

Cork taps 15 and 4 serve as regulators for feeding and removing slurry.

At the end of operation, the magnetostrictive transducer 23 and the drive (not shown) of the drive shaft 12 are turned off.

Unit flushing processes are similar.

when resuming operation, the processes are repeated.
