Abstract
The utility model relates to a sewage discharge pump with an automatic mincing function. The sewage discharge pump with the automatic mincing function comprises a pump body, a lower cover and a vane wheel, wherein the lower cover is installed on the lower side of the pump body, the vane wheel is arranged inside the pump body. A vane wheel cutter is arranged on an inlet surface of the vane wheel, and the lower cover is provided with a cutting disc which is rightly opposite to the vane wheel cutter. Compared with the prior art, the sewage discharge pump with the automatic mincing function has the advantages of being simple in structure, capable of effectively cutting off sundries and the like.
Description
Technical field
The utility model relates to a kind of pollution discharge pump, especially relates to a kind of pollution discharge pump with automatic chopping function.
Background technique
At present, pollution discharge pump is when pumping the sewage of prehensile foreign material such as having more long fibre, weeds, plastic pellicle, the employing tearing type structure that has, the two reamer structures of the employing that also has, namely fill fixedly cutter head in the water inlet of pump, dress rotary cutter before the impeller of pump, all these way structures all complicated, makings had relatively high expectations and chopping function is relatively poor, grade impeller and cutter head etc. often occur is caused pollution discharge pump normally not move by the foreign material winding.
The model utility content
The purpose of this utility model is exactly that a kind of simple in structure and pollution discharge pump that can effectively cut off the automatic chopping function of having of foreign material is provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of pollution discharge pump with automatic chopping function is characterized in that, comprises the pump housing, lower cover and impeller, described lower cover is installed in pump housing below, described impeller is located in the pump housing, and described impeller inlet face is provided with the impeller cutting knife, described lower cover be provided with the impeller cutting knife over against cutting disk;
During operation, sewage is from the lower cover intake impeller, and when running into the prehensile foreign material, the impeller cutting knife of High Rotation Speed and cutting disk enter impeller after with the foreign material chopping and discharge outside the cesspool.
Be provided with the gap of 0.1～0.3mm between described impeller cutting knife cutting edge and the cutting disk.
Described impeller cutting knife is that the blade shroud on the impeller inlet face becomes curved channel to consist of.
Described blade is provided with one piece.
Compared with prior art, the utlity model has following advantage:
Sewage pump is when pumping the sewage of prehensile foreign material such as having more long fibre, weeds, plastic pellicle, can be automatically effluent pond after the prehensile foreign material chopping that is long, smoothly dispatch, because the front of impeller blade itself is exactly cutting knife, so this surface trimming pollution discharge pump is simple in structure and practical.
