Description

(54) DRAINER FOR SEPARATION OF SUSPENSIONS AND SEDIMENT SEALS

R

The invention relates to wastewater treatment, and more specifically to devices for separating suspensions and compacting sludge, for example for purifying wastewater from light and heavy impurities. Such devices are used in the oil refining and petrochemical industries, in metallurgy and cellulose 30 - the paper industry.

The closest to the proposed technical essence and the achieved effect is a settling tank, which includes a housing with inlets - separable suspension and removal of sediment, air and clarified water and a piston with a rod l J.

The lack of a well-known sedimentation tank is an exudation capacity and a significant overall size.

The purpose of the invention is to intensify the process and reduce the size.

The goal is achieved by the fact that the sump is equipped with a cylindrical partition,

The bottom end of which is placed under the pipe supplying the suspension to be divided.

In addition, in the proposed device, the piston is placed in a cylindrical partition, while the rod is hollow.

The drawing shows a sump, general view.

The sump has a housing 1 with keypads 2, inlet pipe 3 and outlet pipes 4-6, a movable port 10, 7, a cylindrical partition 8, check valves 9-11, stop valves 12 and a pressure gauge I. The withdrawal of the ear nozzle 4 is formed by a hollow channel in the rod with a piston 7. The shshkndr 8 is installed inside the sump housing 1.

The sump works as follows.

Through pipe 3, a suspension is fed to the tank, for example waste water,

20 to be cleaned from mechanical impurities. The overpressure is created by a piston 7 device having a reciprocating

When the piston 7 moves downward, an overpressure is created in the sump, the inlet 3 is blocked by the check valve 9 and the outlet 4 of the clarified water and the outlet 5 of the compacted sludge are withdrawn using the reverse valve 1O and 11. The air entering the sediment together with the incoming water prevents the sedimentation of suspended particles and is removed through the nozzle 6. The clarified water is removed through the hollow channel in the piston rod 4, and the sediment which is It is squeezed and compacted under pressure, removed through the nozzle 5. The excess residual pressure in the settling tank is monitored by a pressure gauge 13 and maintained by means of shut-off valves within 3-7 atm. A cylindrical partition 8 is installed inside the sump body 1 in such a way that a zone is formed between the lower end of the cylinder and the inlet nozzle to prevent the incoming slurry, such as wastewater, from entering directly into the cylindrical partition.

The use of the proposed settling tank will provide an economic effect by reducing the production cycle, increasing the efficiency of the process, eliminating the use of reagents that stimulate the process of sedimentation, and reducing the cost of manufacturing, installation, operation and equipment adjustment.
