Abstract

The utility model discloses a sewage treatment pumping station, which is mainly used for the pumping treatment of the domestic sewage. A filtering diversion device can be used to filter the domestic sewage for the solid-liquid separation, and then the blocking of the pump caused by the solid impurities in the sewage, which flows directly through the pump, can be prevented, and the normal function of the pump can be guaranteed. The filtered solids and impurities are deposited on the bottom part of the filtering diversion device, and the filtered sewage can flow in the water tank. When the sewage in the water tank reaches the certain height, a submersible-type sewage pump can be started, and at the same time, the sewage can flow in the filtering diversion device, and then a filter screen can be washed comprehensively, and thereafter the formerly deposited solids and impurities can be discharged out of the pump station along with the sewage together. The filter screen can be cleaned more comprehensively by using the flow deflector, and cannot be blocked, and therefore the resistance in the pipeline is small. The discharged sewage can be prevented from flowing back to the water inlet pipeline to the greatest extent by using the two non-return devices, and therefore the use can be safer. A stirring nozzle can be used to flush the depositions in the case, and then the depositions can be discharged by the pump.

Description

Sewerage treatment promotes pumping plant
Technical field
The utility model relates to a kind of sewerage treatment and promotes pumping plant, belongs to field of Environment Protection.
Background technology
The crisis of water resource has become the focus of global concern, treasures using water wisely, the widespread consensus that becomes everybody that recycles to water resource, and the recycling in process of water, filtration is the conventional technology of water treatment.Because easily causing foreign material, some effluent filters block screen pack, back purge system more complicated, and also anti-cleaning need to consume a large amount of clean water and electric energy.
Summary of the invention
The utility model content is: overcome above-mentioned deficiency, invent a kind of needs by new rinse water, and filter on the basis of sewage, by the water cleaning and filtering net after filtering, and sewage lifting to the sewerage treatment of eminence is promoted to pumping plant.
The utility model solves the technical scheme that its technical problem adopts: this pumping plant by blow-off line, inlet channel, lift check valve, pipe 1, filter guiding device, stir evenly nozzle, backwash pipeline, submersible sewage pump and water tank form, and described filtration guiding device, stirs evenly nozzle, backwash pipeline and submersible sewage pump in water tank.Described inlet channel one end is connected to filters guiding device water inlet, and the other end connects lift check valve; Described blow-off line one end is connected to filters guiding device sewage draining exit, and the other end is connected to pumping plant external pipe; Described backwash pipeline one end is connected to filters guiding device backwash mouth, and the other end connects submersible sewage pump; The described nozzle that stirs evenly is connected on filtration guiding device delivery port; There are screen pack and deflector in described filtration guiding device inside.Screen pack in described filtration guiding device is fixed in the casing and the groove on case lid that filters guiding device, and spot welding fixes, and screen pack filters sanitary sewage, carry out Separation of Solid and Liquid, avoided sanitary sewage directly to flow through pump, the solid sundries in sewage blocks pump, can not normally move; Sewage after filtration flows out by stirring evenly nozzle discharge to water tank from filtering guiding device delivery port, when Water in Water Tanks position arrives certain altitude, submersible sewage pump starts, sewage is discharged to and filters cleaning and filtering net in guiding device, and the solid impurity being accumulated in device is rushed, from sewage draining exit, discharge together; Deflector in described filtration guiding device is welded and fixed with filtering guiding device casing and screen pack, and filtration guiding device backwash mouth and screen pack are divided into three regions of the same area.Described filtration guiding device water inlet and sewage draining exit have check device, the check plate of water inlet is in casing, mainly prevent that sewage backflow is to sanitary sewage end, the check plate of sewage draining exit is outside casing, pipeline adopts eccentric reducer herein, require check plate to rotate and be greater than 90 °, prevent that sewage, the solid sundries of discharging are back in this pumping plant.
The beneficial effects of the utility model are: resistance is little, and sewage is by the filtration of screen pack, and the sewage of the pump that makes to flow through can not block, and pump can normally move, and screen pack is cleaned in time comprehensively in addition, medium circulation more smooth and easy; Screen pack is difficult for stopping up, and the anti-deflector that cleans can be followed comprehensive cleaning and filtering net; Energy-conservation, anti-rinse water is with the sewage after filtering, and saves greatly power and water energy; Pollutant holding capability is large, can hold more impurity, and the safety of this equipment simultaneously increases substantially, and when discharging impurity, has two check devices to control, and makes sewage can not be back to oral siphon.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that sewerage treatment promotes pumping plant.
Fig. 2 is the schematic diagram of the filtration guiding device in pumping plant.
In Fig. 1: 1, blow-off line; 2, inlet channel; 3, lift check valve; 4, manage 1; 5, filter guiding device; 6, stir evenly nozzle; 7, backwash pipeline; 8, submersible sewage pump; 9, water tank.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
In Fig. 1, it is the structural representation of this device, it is that in one, sewerage treatment promotes pumping plant, by blow-off line (1), inlet channel (2), lift check valve (3), pipe 1(4), filter guiding device (5), stir evenly nozzle (6), backwash pipeline (7), submersible pump (8) and water tank (9) and form, wherein filter guiding device (5), stir evenly nozzle (6), backwash pipeline (7) and submersible pump (8) be in water tank (9).Sewage is from pipe 1(4) enter, flow through lift check valve (3), inlet channel (2), from water inlet (5-3), enter and filter guiding device (5), screen pack (5-1) carries out Separation of Solid and Liquid to sewage, solid, impurity are blocked and are deposited in and filters guiding device (5) bottom, and the sewage after filtration is discharged into water tank (9) from delivery port (5-4); When the sewage in water tank (9) reaches certain height, submersible sewage pump (8) starts, sewage is discharged, effluent stream is crossed backwash pipeline (7), backwash mouth (5-6), deflector (5-2), screen pack (5-1), solid, the impurity that will filter guiding device (5) bottom precipitation rush, and from sewage draining exit (5-5), blow-off line (1), discharge.
This device avoids sanitary sewage directly to flow through pump, causes pump to block, and can not normally move; Filtering guiding device has self-cleaning function, and screen pack can not stop up, and the resistance of pipeline is less; And the water of self-cleaning be after using sanitary sewage to filter containing the few sewage of solid impurity, the great like this water resource of having saved; Self-cleaning and blowdown are carried out simultaneously in addition, have also saved electric energy.
