According to the sewage pump provided by the utility model, the impeller plate is arranged at one ends of each the blades, and the impurities in the sewage are successfully discharged after being chopped due to the fact that the both side ends of the blades are in the blade type, so that the impellers are is unlikely to be either twisted or blocked by the impurities in the sewage; and the impeller comprises tow the two blades, one end of each blade is adjacent to an edge of the impeller plate, and the other side end is adjacent to the center of the impeller plate, so that the pollution discharging efficiency is strengthened.

Description

A kind of pollution discharge pump
Technical field
The utility model relates to a kind of pump, is specifically related to a kind of pollution discharge pump.
Background technique
In sewage disposal system, normally adopt pollution discharge pump as delivery means, general main housing, impeller and the motor that comprises with inlet opening and delivery outlet of pollution discharge pump in the market, the driven by motor vane rotary is thrown to sewage on the runner of housing, sewage outside runner outlet duct housing, thereby reach the purpose of blowdown.
In the present pollution discharge pump, impeller is generally monolithic construction, drain opening is less, deslagging ability is relatively poor, particularly in the more sewage of foreign material, in the blowdown such as biomass pool, because the foreign material of more bulk and long fibre shape are arranged in the biomass pool, so when sewage was discharged from by interlobate gap, the foreign material in the sewage are the slit between blocking blades very easily, and causes pollution discharge pump to lose pollution discharge capability; Simultaneously, owing to enwinding impeller easily, the foreign material of long fibre dress cause impeller to be stuck to cause pollution discharge pump to lose pollution discharge capability.
So, need at present a kind of can under the Sewage Environment of complexity, work badly, and deslagging ability not susceptible to plugging pollution discharge pump by force.
The model utility content
Goal of the invention of the present utility model is: the impeller that exists for existing pollution discharge pump is stopped up or twines easily stuck and causes the deficiency of pollution discharge pump cisco unity malfunction by the foreign material in the sewage, providing a kind of can work under the Sewage Environment of complexity, and slag ability not susceptible to plugging pollution discharge pump by force.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of pollution discharge pump, comprise motor, impeller and housing, the two ends of described housing are relatively set with respectively mount inlet and water intake, sidewall outwards projection forms runner in the inboard, be provided with water outlet on the described runner, described impeller is arranged on described enclosure interior, be provided with housing lid on the described motor, described motor is installed in the mount inlet end of described housing by described housing lid, the output shaft of described motor stretches into described enclosure interior by described mount inlet and is connected with described impeller key, described housing sidewall outer installment has and the corresponding waste pipe of water outlet, it is characterized in that, described impeller comprises the impeller plate and minimum two blades, described blade is vertically fixed on described impeller plate lower end, and be tile with respect to the outside projection of the central axis of the impeller plate, described minimum two blades are uniform along described impeller plate central axis, and described blade one side is near described impeller plate edge, and another side is near the position in the described impeller plate center of circle.Driven by motor impeller high speed rotating, the blade of the tile of High Rotation Speed are thrown to sewage on the runner of housing, and sewage enters waste pipe along the water outlet of runner through being arranged on the runner, thereby realize the discharge of sewage; Because only the end at blade arranges the impeller plate, so that impeller is difficult for being stopped up by the foreign material in the sewage, blade one side is near impeller plate edge, and another side has strengthened contaminant removal effectiveness near the position in the impeller plate center of circle.
As preferred version of the present utility model, the two side ends of described blade is blade-like.The impeller High Rotation Speed so that foreign material can be discharged smoothly, has avoided foreign material to twine or clogging impeller the chopping of the foreign material in the sewage.
As preferred version of the present utility model, described blade is two.Larger gap is arranged between blade, prevented that further impeller from being stopped up by the foreign material in the sewage.
As preferred version of the present utility model, described impeller is installed in the axle head of described motor output shaft by bolt and back-up ring.Bolt is set and back-up ring prevents that impeller from coming off from motor output shaft at the axle head of motor output shaft.
As preferred version of the present utility model, described housing inlet end also is provided with supporting frame.Housing is placed on the supporting frame, has avoided the foreign material of sewage bottom to stop up water intake.
Pollution discharge pump of the present utility model is because an end at blade arranges the impeller plate, so that impeller is difficult for being stopped up by the foreign material in the sewage; Two side ends at blade arranges blade simultaneously, and the impeller High Rotation Speed has been avoided by the chopping of the foreign material in the sewage because runner and the pipeline on the stuck impeller of foreign material or the obstruction housing.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
1, impeller comprises two blades, and blade one side is near impeller plate edge, and another side has strengthened contaminant removal effectiveness near the position in the impeller plate center of circle.
2, owing to only at an end of blade the impeller plate is set, and the two side ends of blade is blade-like, and the foreign material in the sewage are shredded rear smooth discharge, thereby so that impeller be difficult for being twined or stopping up by the foreign material in the sewage.
3, simple in structure, easily manufactured.
