Initial power to K 1 is supplied through collector 2 and P 3. The material moves in a spiral downward, sand is removed through P 6 and the drain is removed through P 5 and the collector 4. When sands exit from P 6, they act on the reflector 10. The pulsating nature of the discharge causes the beam 8 to oscillate relative to the hinge 7.

Description

The invention relates to centrifugal type devices for enriching mineral raw materials in a centrifugal field in a liquid medium and can be used in the mining, mineral processing, chemical and other industries.

The purpose of the invention is to increase the reliability of the device by preventing the clogging of sand pipes.

FIG. 1 shows a device for mineral processing, a general view, a section; in fig. 2 - rod in the form of a spiral.

The device includes a block of cylindrical housings 1 and installed from the upper part of the housing 1 a common collector 2 supplying the original power supply with nozzles 3 supplying the initial power supply to each housing 1 and a common collector 4 drainage drainage with fittings 5 draining the drainage from each housing 1. At the bottom Each body 1 has sand nipples 6. Under the body 1 is located on the hinge 7 with the possibility of limited rotation on it in the vertical plane of the rocker 8. At the ends of the rocker arm 8 are installed curved rods 9. The rods 9 are installed

inside the Sand pipes 6, and the number of rods 9 is equal to the number of buildings 1. The rods 9 are made curved in the form of a broken line or in the form of a spiral and mounted on the reflector 10.

The device works as follows.

Mineral feedstocks are fed into the housings 1 through the manifold 2 and the pressure connections 3. Due to the tangential installation of the nozzles 3 to the housings 1, the initial medium is twisted and acquires a rotational motion. Under the action of centrifugal forces, the particles of mineral raw materials are thrown to the walls of the housings 1, moving along the spiral trajectory to the Sand Pipes 6, from where they are removed from the device. The flow of the purified liquid forms an internal ascending pillar and is discharged through the discharge branch pipe 5 and the collector 4. In order to prevent the branch pipe 6 from becoming blocked, it has an appropriate mechanism including rods 9 and reflectors 10 mounted on the rocker arm 8. Under the influence of the flow nozzles 6 to the reflectors 10, due to its pulsating unloading, the rocker 8 oscillates with respect to the hinge 7. The rods 9 that oscillate together with the rocker 8 prevent the clogging of the nozzles 6 and facilitate the passage through their condensed product.

The different shape of the rods 9 is selected depending on the granulometric composition of the condensed product, its concentrations and hydro-mechanical properties.
