(54) INSTALLATION FOR SEWAGE TRANSFER

I

The invention relates to sewage disposal plants and can be applied to sewage systems of residential areas and industrial facilities.

Pumping installations for pumping waste water are known, not from a receiving tank 5 with a waste water grinder and a crusher for separating large inclusions from the drains and then crushing them and lifting them to the collector (If.

These installations are bulky, and in the receiving tank there are heavy sanitary conditions.

A known method of pumping wastewater pumps and water elevators with the separation of these waters into two streams (2).

The installation according to this method is unreliable in operation, since when the grid is clogged, when the wastewater is discharged, these E | odes will flow into the reservoir through the pump, which will adversely affect its performance. In addition, the installation does not provide reliable removal of large inclusions.

A setting for transfer is also known; Wastewater tanks consisting of a tank, above which the machine compartment is located, a pump with suction and pressure pipes | 3 |.

A gravity-flow pipe is attached to the pump's discharge pipe, and below this connection a grate is placed in the pressure pipe, which covers the entire cross-section of the pressure pipe. On the gravity pipe there is a chamber with a filter located above the gravity pipe, above the filter there is a pipe connected to the reservoir.

 This installation has the disadvantage that when the waste fluid passes through the filter installed in the chamber, some of the inclusions contained in the waste fluid are retained in the openings between the filter plates and wedged between the plates, which leads to clogging of the filter.

Filter clogging requires additional supervision of the installation, which reduces the reliability of its operation.

The purpose of the invention is to increase the reliability of work and improve the operating conditions of the installation.

Claims (3)

This goal is achieved by the fact that the filter plates are installed with the possibility of their rotation and are equipped with a reciprocating mechanism in the form of a hydraulic cylinder connected to the pressure pipe with a spring-loaded stem, which is connected by means of a hinge to the filter plates. FIG. I depicts a general view of the installation for pumping wastewater; in fig. 2 shows the position of the filter plates and the spring-loaded stem when wastewater enters the receiving tank; in fig. 3 - the position of the plates of the filter and spring rod during regeneration. The wastewater pumping device consists of a chamber 1 with a filter 2 separated from the liquid flow by a wall 3. Chamber I is connected to the engine room 4 by a gravity pipe 5 and an overflow pipe 6, the first of which is connected by means of a check valve 7 to the pressure pipe 8 of the pump 9. A grill 10 is mounted on the pressure pipe 8. The pump 9 is connected to a suction pipe 11 connected to the atmosphere by means of a ventilation pipe 13 to which the overflow pipe 6 is connected. The filter 2 comprises a frame 14 on which a ball The plates 15 are fixed to the plates 16. The plates 16 are connected to a reciprocating mechanism, made in the form of a hydraulic cylinder and containing a housing 17, inside of which a piston 18 is placed with a rod 19 which is hinged 21 by means of a hinge 20, hub 21 connected to the plates of the filter 16 .. In the housing 17 is placed spring.23. The housing is connected through a pipe 24 to the pressure pipe of the pump and through a drainage pipe 25 is connected to an overflow pipe ... The filter is equipped with stops 26 and 27. The device works as follows. When the pump is turned off, the waste fluid entering chamber 1 flows under filter 2 into self-flowing pipe 5 and then through check valve 7, grill 10, pump 9 and suction pipe 11 into reservoir 12. Large inclusions contained in waste liquid are retained on the grid 10. After filling the receiving tank, the pump is turned on 9. The pressure of the waste fluid created in the pipeline causes the check valve 7 to close. The flow of wastewater through the gravity pipe 5 stops. Large inclusions retained by the grate 10, the liquid of the pressure pipe 8 at the same time. At the same time, the waste liquid through the pipe 24 is fed into the housing 7, acts on the piston 18, displacing it and compressing the spring 23. Moving the piston 18 by means of the rod 19, the hinge 20 and the glands 21 are transmitted to the rod 22, under the action of which the plates 16 are rotated against the stop 26. With the rotation of the filter plates 16, the gaps between them are reduced. Fluid entering the chamber I during operation of the pump, not to flow out through pipe 5, accumulates in chamber I, passes through filter 2 and then flows through overflow pipe 6 to tank 12. At the same time, large inclusions contained in waste liquid are retained under the filter 2 and in the openings between the plates. When the pump 9 is stopped, the pressure in the pressure pipe 8 drops, the non-return valve opens, freeing the path through. gravity pipe 5. Simultaneously with the pressure drop in the pressure pipe 8, the pressure in the 24 n pipe in the housing 17 drops. The spring 23 expands and the piston moves to its original position. With the movement of the piston by means of a puff 19, a hinge 20 and a pull-rod 21, the rod 22 moves, under the action of which the plates 16 rotate up to the stop 27, occupy a vertical position. At the same time, the openings between the plates increase and reach the maximum value when the plates are in a vertical position, and large inclusions retained in the openings between the filter plates are easily removed by the fluid flow. The fluid from chamber I through the gravity pipe 5 through the grate 10, the pump 9 and the suction pipe II enters the receiving tank 12. Installing the filter plates can be rotated and equipped with a reciprocating displaced valve mechanism that improves the operating conditions, as by improving the regeneration of the filter, clogging is virtually eliminated. Claims An installation for pumping wastewater, comprising a pump with a suction pipe and a pressure head equipped with a grate, a chamber with a plate filter, an overflow pipe and gravity flow, connected to the pressure pipe by means of a non-return valve, in order to increase reliability and improve operating conditions by providing a reciprocating movement of the filter plates, it is equipped with a hydraulic rod connected to the pressure pipe with a spring-loaded stem connected by a ball valve to filter plates.
