Low export direction, meanwhile, vacuum is formed in impeller center, under atmospheric pressure effect, the water at impeller eye enters impeller
Center, such impeller constantly rotate, and water constantly enters and throws away, and are formed the continuous work of centrifugal pump.Sewage treatment from
Core type reuse water pump could first plus diversion will work normally, this not only causes resource when booting since startup-shutdown pumping frequency is numerous
Waste, while load is increased to device, burden is increased to employee, workload increases.
Utility model content
The utility model provides a kind of sewage treatment centrifugal pump, it is therefore an objective to by the way that centrifugation is automatically added water and prevented to water pump
Water in pump is flowed into pond, and the unlatching of centrifugal pump is made to no longer need to fill the water by artificial mode, mitigate employee burden and
Workload.
The technical solution adopted in the utility model is as follows:
A kind of sewage treatment centrifugal pump, including pump housing water inlet pipe and pump housing chamber, the pump housing water inlet pipe and pump housing chamber connect
It meeting place and is equipped with sea cock and valve, be communicated with pump housing outlet pipe at the top of the pump housing chamber, the pump housing outlet pipe is communicated with L-type conduit,
The pump housing chamber is externally provided with header tank, and the header tank bottom is equipped with aqueduct, the aqueduct respectively with pump housing outlet pipe and L
The connection of type conduit, the L-type conduit is located at the bottom of the aqueduct, slidably connects foam block in the L-type conduit, described
It is connected with water-stop sheet at the top of foam block, the inner wall of the water-stop sheet and the aqueduct is slidably connected.
Further, the pump housing water inlet pipe and pump housing chamber junction are equipped with groove, and the sea cock and valve and the groove cooperate
Connection.
Further, the sea cock and valve includes the tube body for closing hollow out, is equipped with non-return pad in the tube body.
Further, iron is equipped between the foam block and the water-stop sheet.
Further, the aqueduct and the L-type catheter section are square-section.
Further, be located at the aqueduct in the aqueduct and the L-type conduit connection be equipped with open slot, it is described every
Water plate is slidably connected with the open slot.
The utility model has the beneficial effect that
(1) the utility model sea cock and valve is located in the groove of pump housing water inlet, and sea cock and valve includes tube body and manages intracorporal
Non-return pad, since impeller center forms vacuum under centrifugal pump working states', non-return pad can open pump housing water inlet line, work as centrifugation
When pump stops working, the water in centrifugal pump can flow back, and non-return pad can close water inlet line under the extruding of water, and then make to be centrifuged
There is water always in pump.
(2) the utility model L-type conduit is connected to pump housing outlet pipe, aqueduct respectively, when the water in centrifugal pump is reduced,
Foam block in L-type conduit communicates aqueduct and pump housing outlet pipe, catchments because the water surface reduces that water-stop sheet is driven to reduce
Water in case can supplement the water in centrifugal pump, and foam block drives water-stop sheet by water guide duct occlusion, is further ensured that because the water surface rises
Water has been remained in centrifugal pump, mitigates the burden and workload of employee.
