Description

The invention relates to water treatment and can be used in wastewater treatment of ferrous and nonferrous metallurgy enterprises, the mining industry and in engineering.

The purpose of the invention is to improve the quality of purified water by eliminating sediment in it, as well as simplifying the process of its discharge.

1 shows a schematic representation of the proposed device, a general view, a section; figure 2 - the node in figure 1; on fig.Z - section a - a in figure 2.

The sump contains a housing 1, a tangentially located device for

supplying contaminated water with a supply tray 2, a tray 3 for draining clarified water, a bunker 4 for collecting sludge located in the lower part of the settler and separated from its upper side part by a closure body 5 whose lateral surface has a conical shape. The sump is equipped with a coaxially arranged pressure chamber 6 with inlet pipes 7 and outlet 8 of the transporting medium. The locking body 5 is equipped with a spool 9, which is located coaxially with the nozzle 8 of the outlet of the transporting medium. The locking body 5 is equipped with a valve 9 by means of a rigid connection 10, which has an adjusting element 11, for example, in the form of a thread

howl coupling. Using the adjusting element 11, the spool 9 is installed with the possibility of contact with the pipe 8 outlet transporting medium.

A diaphragm 12 is located in the lower part of the locking member 5. A closed volume 13 is formed between the surfaces of the coaxially arranged pressure chamber 6, the locking member 5 and the diaphragm 12.

The diaphragm 12 in the central part has a centering element 14 for ensuring the movement of the locking member 5 in a strictly vertical direction.

The nozzles 15 are tangentially located along the outer diameter of the diaphragm 12. The end of the branch pipe 8 of the transport medium discharge is brought to the bottom of the bunker 4 for collecting sediment and is installed, for example, coaxially with the bunker. In the lower part of the bunker 4 above the pipe 8 of the outlet of the transporting medium and coaxially it has a pipe 16 of sediment.

The sump for wastewater treatment works as follows.

The contaminated water enters the housing 1 through the supply tray 2 of a tangentially located device for the supply of contaminated water. From the upper part of the tank 1, the clarified water is discharged through the tray 3 of the device for draining the clarified water. Sludge sedimented in the tank 1 of the settler, such as scale, with the open position of the locking member 5 enters the bunker 4 to collect the sediment, where it accumulates and simultaneously thickens.

When a certain level of sediment is reached in the bunker 4, controlled in a known manner, a pump (not shown) is turned on, which supplies the transport medium through the inlet 7.

Clarified water, for example, can be used as a transport medium. As a result of the transporting medium entering a coaxially arranged pressure chamber 6, the pressure in the latter increases and a lift force occurs.

In the closed volume 13, formed by a coaxially arranged pressure chamber 6, a locking member 5 and a diaphragm 12, pressure also increases, and the resulting lifting force lifts the locking member 5 to the upper position Closed.

The lateral conical surface of the closure member 5 fits snugly against the corresponding surface of the upper part of the bunker 4 for collecting sludge.

At the same time transporting medium under pressure from a closed volume 13

out through the tangentially positioned nozzles 15 of the diaphragm 12. As a result, a reactive force is created which turns the locking member 5.

Through hard link 10 along with

the valve 5 lifts the spool 9, which opens the pipe 8 of the outlet transporting medium. The control element 11 contacts the spool

9 with a pipe 8 outlet transporting medium. Since the end of the nozzle 8 of the transport medium discharge is brought to the bottom of the bunker 4 for collecting sediment and is installed, for example, coaxially with the bunker, intensive sedimentation of the sediment compacted in it occurs, which due to the location of the coaxially installed nozzle 16 above the nozzle 16 is picked up by the transport medium stream and removed is

from the sump.

The transport medium entering the hopper 4 through the outlet nozzle 8 removes the sediment compacted in it, and the sediment 4 is unloaded under pressure through

outlet pipe 16 sediment.

After a predetermined process of unloading sediment has expired, the supply of the transporting medium through the nozzle 7 supply stops, the pressure in the coaxially arranged pressure chamber 6 drops, the locking member 5 lowers and takes the Open position, after which the sediment accumulation begins again. Sludge removal operations can be automated.

The use of the proposed settling tank allows, through the use of a single means, namely a transporting medium, to successively carry out both the separation of the settling zones and the accumulation of sludge, and the erosion and unloading of the latter from the settling basin; exclude the discharge of sediment into the clarified water and improve the quality of the treated water; increase the reliability of the building by

simplify the process of sludge removal.
