Description
Technical field
The utility model is related to a kind of electrodynamic pump, more particularly to a kind of sewage/waste electrical submersible pump.
Background technology
Submersible pump is one kind of pump, and submersible pump rotates by motor impeller, water is pumped into from suction inlet and from row
Work of drawing water is completed in outlet discharge, and the motor of submersible pump has good leakproofness with extraneous, and submersible pump can be completely immersed in
It works in water.For the field of employment of different quality, submersible pump can be divided into clear water submersible pump, sewage submersible pump and seawater
Submersible pump etc..
Existing publication No. be CN104265680A application for a patent for invention disclose a kind of immersible pump, including the pump housing, impeller,
Inlet opening and water outlet, inlet opening are located at pump housing lower end, and impeller is arranged in the pump housing close to the position of inlet opening, passes through motor band
The rotation of movable vane wheel is drawn water with realizing.But when extracting sewage of the bottom containing deposit using the immersible pump, due to being located at sewage bottom
The deposits such as sludge it is generally more sticky, so being difficult to be sucked by impeller, the extraction for causing sewage and dirt is not clean enough.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of sewage/waste electrical submersible pump,
The deposits such as sludge and sewage can effectively be extracted.
The above-mentioned technical purpose of the utility model technical scheme is that：A kind of sewage dirt diving
Electric pump including casing and pump case, is provided with motor, impeller, the motor and impeller is provided in the pump case in the casing
Between be provided with shaft, the pump case offers the suction inlet for water inlet, the outlet for draining, and the motor is by turning
Axis driving impeller rotation is drawn water with realizing, it is characterized in that：The shaft is pierced by from suction inlet to be extended to outside pump case, the shaft position
Wheel is stirred evenly in the end set outside pump case, the shaft drives impeller and stirs evenly wheel rotation simultaneously.
Through the above technical solutions, in use, this submersible pump is put into sewage to be taken out, and it is located at pump case as far as possible
The underface of casing, this submersible pump is powered, and motor operating drives shaft rotation, shaft while impeller and stirs evenly wheel rotation
Turn, stirring evenly wheel will be bound together positioned at the impurity such as water-bed sludge and sewage, and impeller rotation makes suction inlet generate suction, will stir
Sewage, sludge after even discharges pump case out of suction inlet sucking pump case from outlet, therefore can extract sewage and dirt
It is more clean.
Preferably, the wheel that stirs evenly is connected with shaft thread, and the direction that the shaft rotates forward turns with that will stir evenly wheel and be tightened against
The direction of axis is opposite.
Through the above technical solutions, turn the direction for stirring evenly wheel toward fastening when shaft rotates forward, and the motor of submersible pump
The function that need not be inverted so during normal work, stirs evenly wheel and is difficult to loosen from shaft.
Preferably, it is described stir evenly be provided on wheel it is several stir evenly blade, several blades that stir evenly are compared with stirring evenly wheel
Axisymmetrical, and coiled in the shape of a spiral on the side wall for stirring evenly wheel.
Through the above technical solutions, the spiral helicine blade that stirs evenly can play the effect of good stirring deposit, in sludge
Resistance during middle rotation is also smaller, and when stirring evenly blade and hard object and hitting, hard object tilting action in the surface for stirring evenly blade,
And launched under the spiral helicine guiding role for stirring evenly blade to other directions, reduce the probability for stirring evenly blade damage.
Preferably, the width for stirring evenly blade makes the outer diameter for stirring evenly wheel entirety along being incremented by towards the direction of pump case
Edge is presented towards the incremental trend in the direction of pump case.
Through the above technical solutions, the structure for making to stir evenly wheel is similar to the impeller of self priming pump, then water can will be located at by stirring evenly wheel
The impurity such as the sludge at bottom are involved in impeller direction, and are discharged from the radial direction for stirring evenly wheel, and sludge can be stirred evenly fully with sewage.
Preferably, the pump case is provided with pedestal backwards to one end of casing, and the wheel that stirs evenly is located in pedestal.
Through the above technical solutions, since stirring wheel is located at outside pump case, so pedestal can play the role of protecting stirring wheel,
The presence of pedestal can make this submersible pump all be easy to be placed vertically on ground or the bottom simultaneously.
Preferably, the pedestal includes filter mantle, and the filter mantle covering is uniformly opened up on suction inlet, the filter mantle
There are several filter hole.
Through the above technical solutions, during motor operating impeller rotation, suction inlet generates suction, and sewage passes through filter bowl mistake
After filtering large-scale impurity, enter from suction inlet in pump case, reduce the probability that large-scale hard object enters pump case damage impeller.
Preferably, the shaft is close stirs evenly the clip slot for offering to facilitate external spanner clamping on the side wall of wheel.
Through the above technical solutions, since the side of shaft can rotate for cylindrical surface and compared with motor, so in shaft
It is upper dismounting stir evenly it is more inconvenient during wheel, in shaft set clip slot after, external spanner can easily clamp clip slot and compared with turn
Axis, which turns, stirs evenly wheel, realizes the dismounting for stirring evenly wheel.
Preferably, the shaft, which includes being located in pump case, enters water section and the dryer section in casing, it is described enter water section
It is made of stainless steel, the dryer section is made of ordinary carbon steel.
Through the above technical solutions, being made of stainless steel due to entering water section, it is not easy to so entering water section and being contacted for a long time with water
Get rusty, dryer section, which is located in casing, to be difficult to contact with water, then the problem of rustiness of dryer section can be ignored, ordinary carbon steel into
This is lower compared with stainless steel, and dryer section is constructed to reduce the manufacture cost of whole shaft by ordinary carbon steel.
In conclusion the utility model having the beneficial effect that in contrast to the prior art：This sewage/waste electrical submersible pump can be
The deposits such as sludge are effectively extracted while extracting sewage, at the same it is simple in structure, it is easy to dismount.
