Description

A kind of sewage lifting pump station
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of Sewage Disposal, particularly a kind of sewage lifting pump station.
Background technology
Along with the development of economic society and the raising day by day of people's living standard, the environmental quality requirement that people live to oneself is more and more higher.At present, the building construction of China is mainly divided into this five large class of room for room for business unit, hospital, hotel, highrise building and resident's residence, and generally, underground sewage process chamber has all been set up in the house that build the present age.Because the sewage area of processing is very large, so built Wastewater Treatment Plant, in the mode focusing on, realize the processing of sewage.Focusing on of sewage need to be concentrated the large area sewage of discharge to be transported to Wastewater Treatment Plant, and in sewage transport process, because road is far away, sewage need be delivered to Wastewater Treatment Plant by sewage conduct again after sewage lifting station promotes.
The sewage lifting pump station that China's prior art is used, conventionally adopt the mode of sump to carry out effluent discharge, this sewage lifting pump station mainly comprises: sump, dredge pump, fluid level controller and electric control box, in dredge pump and fluid level controller, be located at sump, and both are unified by cable access electric control box separately, wherein, dredge pump is fixed in sump by coupling device, water level in sump starts to raise, when water level reaches the height that fluid level controller sets, fluid level controller excites electric control box, electric control box starts to start dredge pump, dredge pump is by sewage lifting and be delivered to outdoor drainage well or city planting ductwork.
Existing market has been made various improvement to sewage lifting pump station, and some has also applied for patent, for example, in Chinese patent literature data, disclose a kind of sewage lifting pump station and applied for patent [application number: 201320218919.9; Notice of authorization number: CN203230035U], it comprises casing, the top of this casing is provided with at least one outlet of sewer; At least one cutting submersible pump of being located at casing, its delivery port communicates with outlet of sewer; One liquid level sensor, it is installed on the cavity of casing; One control system, it comprises controller, this controller is connected in the supply line of the set valve of liquid level sensor, sewage import and cutting submersible pump.
Above-mentioned sewage lifting pump station has certain intelligent degree, can control the startup of sewage imported valve and close according to the variation of wastewater level, and can also be according to the cutting submersible pump of the automatic box house of the sewage quantity of box house, but it is built in header tank by dredge pump, because dredge pump moves for a long time under the adverse circumstances of contact sewage, reduced the application life of foul water pump, simultaneously because it is fixed in sump by coupling device, install loaded down with trivial detailsly, maintenance cost is higher.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of easy for installation, long service life, the sewage lifting pump station that pollution discharge capability is good.
The purpose of this utility model can realize by following technical proposal: a kind of sewage lifting pump station, comprise header tank, dredge pump, electric control box and outlet pipe, on described header tank, be provided with several dirt inlets, it is characterized in that, described header tank has stage portion and top, at least two dredge pumps are installed in the stage portion of described header tank, described dredge pump and electric control box are connected by electric wire, described dredge pump has water inlet and delivery port, the water inlet of described dredge pump is provided with the cutter that the main shaft with dredge pump is connected mutually, the delivery port of described dredge pump is connected with outlet pipe, the top of described header tank is provided with baroswitch, one end of described baroswitch has stretches into the piezometer tube of measuring hydraulic pressure in header tank, described baroswitch and electric control box are connected by electric wire.
The sewage of this sewage lifting pump station enters header tank by dirt inlet, utilize the cutter cutting of dredge pump, some or city planting ductworks outer by dredge pump discharge chamber again after pulverizing compared with bigger material in sewage, avoided large foreign material to stop up in pump, thereby improved the ability of sewage effluent.Water level in header tank rises to certain altitude, and when the piezometer tube that is installed on the baroswitch at header tank top detects hydraulic pressure and arrives certain numerical value, the dredge pump that the closed power supply of electric control box starts to start is wherein started working; Water level in header tank drops to certain altitude, and when the piezometer tube that is installed on the baroswitch at header tank top detects hydraulic pressure lower than certain numerical value, the closed power-off of electric control box stops the work of all dredge pumps.Two dredge pumps take turns to operate, and can make every dredge pump obtain maximum time rest, can solve the heating problem that dredge pump works long hours and causes, and have greatly extended the application life of whole sewage lifting pump station.Dredge pump is installed on and on the outer wall of header tank, not only makes it easy for installation and avoided dredge pump Long Term Contact sewage and the shortcoming that shortens application life.
In above-mentioned a kind of sewage lifting pump station, on described header tank, be provided with backwash tube, described backwash tube one end is connected with the delivery port of dredge pump, and the other end is communicated with the top of header tank.The setting of backwash tube can be cleared up the foreign material on baroswitch and header tank inwall, can allow the normal work of dredge pump also can allow foreign material more thoroughly discharge pumping plant.
In above-mentioned a kind of sewage lifting pump station, described outlet pipe comprises outfall sewer and the quantity exit branch consistent with dredge pump, one end of described exit branch is all connected with one end of outfall sewer, the other end of exit branch is connected with the delivery port of corresponding dredge pump respectively, on described exit branch, be provided with flap valve, on described outfall sewer, be provided with pipeline main valve.
In above-mentioned a kind of sewage lifting pump station, the top of described header tank is provided with exhaust opening.Because drawing water of dredge pump is limited in scope, in corner, easily accumulate dirt, and these dirts can produce pernicious gas, cause pressure in header tank to increase, thus exhaust opening the effective safety that has ensured this sewage lifting pump station is set.
In above-mentioned a kind of sewage lifting pump station, described dredge pump is connected by the substrate with spiral case mutually with stage portion.
Compared with prior art, outer wall and every dredge pump that the dredge pump of this sewage lifting pump station is arranged on header tank take turns to operate, and make it easy for installation, long service life, and pollution discharge capability is good.
