Abstract

The invention relates to the purification of liquids, the thickening of suspensions and the trapping of fine-grained fractions and can be used in coal preparation processes. The purpose of the invention is to intensify the process of regeneration of the filtering surface. The initial suspension is fed to the rotor (P), divided into phases: lightly flows into the sump, and heavy is discharged into the nozzle. When P is rotated, the ball elements move along the inner surface of the filter element, clearing it, enter the cells of the annular tray, reload into the groove and roll down and circulate inside the rotor. When the eccentric is rotated, the slide moves the piston rod in a reciprocating motion to move the pistons so that the clarified water flows to the sprinkler, ensuring that the outer surface of the filter element is washed. 1 hp f-ly, 2 ill.

Description

The invention relates to devices for cleaning liquids, thickening suspensions and trapping fine-grained fractions, and can be used in technological processes of enrichment of coal and other mining materials. fishing

The purpose of the invention is to intensify the process of regenerating the filtering surface.

FIG. 1 shows the device, longitudinal ET; FIG. 2 is a view A of FIG. one.

The device dp for clarifying gshamovy waters includes a housing 1, in which

bearings are fitted with hollow derLori-., rotor 2, with filter element 3 attached to it, sludge supply pipes 4, clear water outlet 5, condensation extractor 6 and mounted in the end cover of the housing, drive shaft 7, balloon elements 8, located at the end of a large rotor diameter 2, an annular loop 9 with radially located and cell-shaped partitions, a groove 10, a cylinder 11 with a brush 12 with opposed pistons 13, a slide 14 that covers an eccentric 15, installed on the drive shaft 7, sump 16 o luminous water pipe

wires 17 with check valves 18 - sprinkler 19,

A slurry clarifier is operated in a very consistent manner.

Rotor 2 with attached to it. filter element 3 is rotated from the drive shaft 7, through the pipe 4 into the inner space of the rotor 2 is fed sludge, the latter i is divided into phases. The clarified water flows into the sump 16 and through the nozzle 5, which maintains the predetermined level of clarified water in the device housing 1, is removed outside. The thickened sludge is discharged into the nozzle 6.

When the rotor 2 rotates, the spherical elements 8 move along the inner surface of the filter element 3, enter the KOjjbueBoro cells of the tray 9, are reloaded into the groove 10, and, rolling down the inclined plane, circulate inside the rotor 2, ensuring active cleaning surface combined with a stream of sludge, large sediment deposits.

When the eccentric rotates, the 15 link 14 communicates the reciprocating movement of the rod 12, which moves the pistons 13 in the cylinder 11. At the same time, the clarified water from the sedimentation tank MB flows through the pipelines into the cylinders. lindr 11 is injected into the sprinkler 19, ensuring active flushing with a water jet under pressure from the outside of the filtering surface. In this case, the entrained particles of the suspension are pushed into the internal cavity of the rotor.

The invention allows to intensify the process of regeneration of the filtering surface without increasing energy consumption.

The economic effect of the invention is provided by the possibility of extracting additional raw materials and increasing the productivity of the sludge water treatment process.
