Description
Technical field
The utility model is related to a kind of sewage lifting devices, are promoted more particularly, to a kind of full-automatic sewage of band backwash
Equipment.
Background technology
Sewage lifting device with dredge pump is typically mounted at the bottom in the header tank at the sewage bottom, for discharging
The sewage being pumped into header tank.With constantly pouring in for sewage, dirt can be cumulative in header tank bottom namely pump bottom.Especially
It is when being again turned on sewage lifting device progress blowdown after shutting down a period of time, part dirt may dry up, and depend merely on pump
Suction possibly these dirts can not be discharged, need first to carry out the operations such as inverse-washing, dilution, be just unlikely to influence pump in this way
Normal work.
But the existing sewage lifting device for being equipped with backwash has following shortcoming：1. its water backwashed is also
Come from the sewage of header tank, it is filtered to be easy to block the smaller backwash tube in aperture often containing larger impurity；2.
Solid-liquid separator is only rinsed when it is backwashed, there is no the imports for the bottom and dredge pump for rinsing header tank；3. backwash is not
Controllably.
And if backwash tube is blocked or does not rinse backwash tube water tank bottom and the mud of blowdown pump inlet, can reduce dirt
The stability and durability of water lifting means increase manufacture and the maintenance cost of sewage lifting device.
Utility model content
Technical problem to be solved in the utility model is just to provide band recoil a kind of simple in structure and that backwash is controllable
The sewage lifting device washed, the water of backwash fall larger impurity by strainer filtering, will not block backwash tube, it is ensured that water
Bottom portion will not generate mud, improve the stability and durability of sewage lifting device, reduce sewage lifting device manufacture and
Maintenance cost ensures sewage lifting device work steady in a long-term.
Above-mentioned technical problem is solved, technical solution is used by the utility model：
The sewage lifting device of a kind of band backwash, including a header tank 4, two proof submersible sand discharging pumps 5, two Rose Boxes 10, each

Water outlet and water inlet are entered in header tank；When the water level of header tank reach a certain height, wherein a pump startup, catchments
Sewage in case enters from this proof submersible sand discharging pump water inlet directed downwardly in pump, then from the water outlet of pump by Rose Box enter into
Waterpipe and outlet conduit；The non-return valve of inlet channel is closed at this time, and the non-return valve of outlet conduit is opened, and such sewage just conveys
Into municipal drainage.When this pump, which stops another, to be started, operation principle is same as above.
Advantageous effect：Since water inlet pipe and outlet pipe are all the preceding parts that are located at Rose Box, in this way, the water inlet of water inlet pipe is
It first passes through Rose Box and enters back into header tank later, dredge pump is behind Rose Box plus backwash tube, so backwashing water
It is middle without big impurity, backwash tube will not be blocked；Meanwhile the backwash tube for being directed toward water tank bottom and blowdown pump inlet can remove water
The mud of bottom portion and dredge pump water inlet is rinsed the dirt below the pump housing, dilutes, and allows dirt with sewage quilt
Proof submersible sand discharging pump is smoothly discharged, and is prevented mud rubbish etc. from being accumulated in bottom of pond, is used manpower and material resources sparingly, and ensures that sewage lifting device can be grown
Phase fault-free works normally.
