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.
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 a kind of sewage lifting of band backwash simple in structure and sets
Standby, the water for entering header tank falls larger impurity by strainer filtering, will not block backwash tube, it is ensured that water tank bottom will not
Mud is generated, improves the stability and durability of sewage lifting device, reduces manufacture and the maintenance cost of sewage lifting device, is protected
Demonstrate,prove 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
From a water inlet pipe 2 and an outlet pipe 1 equipped with non-return valve 11, two proof submersible sand discharging pumps are fixed on bottom and its water inlet in header tank
Downward, sewage draining exit is then connect with Rose Box by pipeline, water inlet pipe, outlet pipe connecting pin be designed with branch and be connected to two
On Rose Box；It is characterized in that：The Rose Box is closed elongated vessel, and one end open connects outlet pipe, another end opening
By opening connection water inlet pipe on pipeline connection dredge pump, midfeather, filter screen (9) is located at connection dredge pump end, mistake in container
Strainer 9 is made of smooth, the parallel a plurality of cylindrical stainless steel filtering rod in surface；In the proof submersible sand discharging pump sewage draining exit and mistake
In the connecting pipe of filter box, equipped with the backwash tube (8) for being directed toward header tank bottom and blowdown pump inlet.
Preferably, container intracavity is divided into two parts by the filter screen (9), and respectively leading portion and back segment, back segment is
One end socket of Rose Box, filter screen are installed between the leading portion and back segment of the babinet connected by flange arrangement and are connected as a single entity.
Since filtering rod surface is smooth, it is not easy corrosion and is not easy to plug, and is easy to clean.
The course of work：It is in order to which them is allowed to take turns to operate to set two proof submersible sand discharging pumps.Usually, the water level of header tank is not
When reaching predetermined altitude, submersible sewage air pump inoperative, sewage is from water inlet pipe (non-return valve opening) respectively through two filters, Liang Tai
The sewage draining exit of proof submersible sand discharging pump is entered in header tank.When the water level of header tank reach a certain height, wherein a dredge pump
Start, the water in header tank enters from this proof submersible sand discharging pump water inlet directed downwardly in pump, then pass through from the sewage draining exit of dredge pump
Rose Box enters inlet and outlet pipes；The non-return valve of inlet channel is closed at this time, and the non-return valve of outlet conduit is opened, this
Sample sewage is just transported in 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 passing through Rose Box and enters back into header tank later, dredge pump is to add backwash tube on the pipeline behind Rose Box, so
Without big impurity in backwashing water, backwash tube will not be blocked；Meanwhile it is directed toward the backwash of header tank bottom and blowdown pump inlet
Pipe can remove the mud of water tank bottom and dredge pump water inlet or the dirt below dredge pump is rinsed, is diluted, and make dirt
It can smoothly be discharged by proof submersible sand discharging pump with sewage, prevent mud rubbish etc. from being accumulated in bottom of pond, use manpower and material resources sparingly, ensure sewage
Lifting means energy long trouble free works normally.
