Abstract

The invention relates to water purification devices and can be used in sewage treatment of metallurgical and mining industries. The purpose of the invention is to increase the efficiency of wastewater treatment and sludge dewatering, as well as increase the reliability of the sump. Water enters through conduit 2 into hydrocyclone 3, where large particles are separated, which are removed into bunker 13. At the same time, very large inclusions are crushed using vertical fins mounted on the shaft. Fine-dispersed psham with water comes out of the 1-slope hydro- line through the drain channel with the swirler 4 and enters the chamber of the flocky 5. Fine-dispersed psham falls out into the ring tray 11 and is discharged separately from the crust-dispersed psham through nozzles 12. 5 ill. € (L with

The sump consists of body 1, pipeline 2. For supplying polluted water, pressure hydrocyclone 3 with annular drainage of fluid with a swirler 4, camera 5 of the foculations, 20 thin-layer modules 6, pipe 7 for discharging clarified water, truss 8. to collect sediment, drive 9 and central shaft 10. In the bottom of the settler there is an annular sludge trap 25 current 11 with a nozzle 12 for draining slurry pulp, and a hopper 13 for large particles with a nozzle 14 for their withdrawal. Below the hydro cyclone 3, the coarse particles detained in the hydro side are fixed through an annular gap between the central shaft 10 and the conical part of the hydro cyclone 3 and enter the hopper 13 for coarse particles through pipe 15 with the socket 16 and are removed through the pipe 14. The pipe 16 prevents fine spun from the chamber 5 from precipitating flock and settling zones in the hopper 13, thereby reducing the content of fine particles in the coarse fraction, which contributes to a better dehydration. Random large inclusions larger than the width of the annular gap between the shaft 10 and the conical part of the hydro cyclone 3 are stuck in the hydro cyclone, crushed by ribs 17, and then entered into the pipe 15 and further into the hopper 13, from where they can be directed to dewatering bunkers.

The use of the proposed device will improve the efficiency of classification and dehydration.

on the coaxial shaft, the vertical pipe-30 of the coarse fraction and the scrap 11, from where it is removed through the nozzle 12.

Large particles retained in a hydraulic pitch through an annular gap between the central shaft 10 and the conical part of a hydro cyclone 3 enter the hopper 13 for large particles through pipe 15 with a socket 16 and are removed through pipe 14. The spigot 16 prevents fine spun from the flocking chamber 5 from precipitating settling in the hopper 13, due to which the content of fine particles in the coarse fraction is reduced, which contributes to a better dehydration. Random large inclusions larger than the width of the annular gap between the shaft 10 and the conical part of the hydro cyclone 3 are stuck in the hydro cyclone, crushed by ribs 17, and then entered into the pipe 15 and further into the hopper 13, from where they can be directed to dewatering bunkers.

BA 15 with a bell 16. The diameter of the bell is equal to the diameter of the hopper 13 or slightly exceeds it. On the shaft 10 (in that area of it, which runs inside the conical part of the hydrocyclone), vertical ribs 17 are installed.

The sump works as follows.

Water enters the housing 1 through conduit 2 and first enters the injected hydrocyclone 3. In the pressure hydrocyclone 3, large particles and random objects are separated. Next, the water passes through the swirler 4,

Invention Formula A sump containing a body, a hydrocyclone installed in the center of the body, a pipeline for supplying contaminated water, a sludge hopper located under a hydrocyclone, a clarified water outlet nozzle, characterized in that in order to increase the efficiency of wastewater treatment and sludge dewatering. thanks to which flocculation chamber 5 is in the chamber as well as increase of reliability a rotational movement is created to facilitate flocculation. Coming out of the flocculation chamber, the flow of liquid turns up and passes through the thin-layer modules 6, where further clarification of the water occurs. The clarified water is removed through the nozzle 7 of the clarified water.
