Description

The invention relates to the enrichment of minerals, is intended for the separation of materials according to density and can be used in the mining, coal and construction industries,

The purpose of the invention is to increase the efficiency of the separation process and the specific productivity.

The drawing shows a device for enrichment and dewatering sludge, general view.

The device includes a housing 1 mounted inside the housing 1 on the shaft 2 a spiral 3, a drive 4 and a boot, a device 5 for supplying power to the housing 1. The shaft 2 is hollow with holes 6 therein. The loading device 5 is made in the form of a pipe entering the shaft 2. Inside the housing 1, a vortex transducer 7 is located across it. The housing 1 is installed horizontally and is made in the form of a hollow cylindrical part 8 with adjacent large bases with hollow truncated main 9 and an additional 10 cones. The vortex generator 7 is made in the form of an annular partition and is installed in the center of the cylindrical part 8 of the housing 1. The cylindrical part 8 of the housing 1 is divided by the vortex generator 7 into the deposition chamber 11 and the vortex chamber 12 located at opposite ends of the housing 1. its lower part is fitted with a device 13 for unloading sands and a device 14 for unloading industrial product, made in the form of nozzles. The drainage device 15 is made in the form of a drainage pipe installed in the lower part of the housing 1. An internal cone is mounted on shaft 2

16. An additional helix is wound on the inner cone 16. The angle of taper of the truncated cone 9 installed on the side of the loading device 5 is 20-26 °, and the angle of taper of the additional truncated cone 10 equals the angle of taper of the equidistant inner cone 16 installed in it and 10 - 15 °. The direction of the winding of the helix 3 and the additional helix 17 is opposite. The boot device can be made in the form of a tangential nozzle 18.

The device works as follows.

The original pulp is fed through the loading device 5 into the hollow shaft 2 and through the holes 6 enters the deposition chamber 11. Thick particles of rock under the force of gravity and centrifugal force are deposited on the cylindrical part 8 of the housing 1} by the spiral 3 are transported along the truncated cone

9, at the same time dewatering and discharging through the device 13 for unloading sands. Light particles are held in the surface layer and are poured with water through the vortex generator 7 into the vortex chamber 12. When pulp flows through the drainage device. 15, a rotational movement, amplified by the vortex generator 7, occurs, resulting in heavy. the grains are thrown against the wall and, deposited in the vortex chamber 12, are transported by an additional spiral 17

on additional truncated cone

10, held by the inner cone 16, and in a dewatered form, are discharged through the tool 14 to unload the middlings. Water with the most

fine, silty particles are drained through the drainage device 15.
