Abstract
The invention relates to a sewage pump with an automatic cut-up function. The sewage pump comprises a pump body, a lower cover and an impeller. The lower cover is arranged below the pump body. The impeller is arranged in the pump body. An impeller cutter is arranged on an inlet face of the impeller. A cutting disc right opposite to the impeller cutter is arranged on the lower cover. During operation, sewage is sucked into the impeller from the lower cover, and when the sewage pump meets winding impurities, the high-speed-rotating impeller cutter and the cutting disc cut up the impurities which then enter the impeller and are discharged out of a sewage pool. Compared with the prior art, the sewage pump has the advantages of being simple in structure, and impurities can be effectively cut off.
Description
Technical field
The present invention relates to a kind of pollution discharge pump, especially relate 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, some employing tearing type structures, the two reamer structures of the employing also having, in the water inlet of pump, fill fixedly cutter head, dress rotary cutter before the impeller of pump, all these way structures all more complicated, makings had relatively high expectations and chopping function is poor, grade often occur that impeller and cutter head etc. are caused pollution discharge pump normally not move by foreign material winding.
Summary of the invention
Object of the present invention 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 defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A 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 impeller cutting knife, cover under described be provided with impeller cutting knife over against cutting disk;
During operation, sewage is from lower cover intake impeller, and when running into prehensile foreign material, the impeller cutting knife of High Rotation Speed and cutting disk will enter impeller and discharge outside cesspool after foreign material chopping.
Between described impeller cutting knife cutting edge and cutting disk, be provided with the gap of 0.1～0.3mm.
Described impeller cutting knife is that the blade shroud on impeller inlet face becomes curved channel to form.
Described blade is provided with one piece.
Compared with prior art, the present invention has the following advantages:
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 prehensile foreign material chopping that is long, dispatch smoothly, because impeller blade above itself is exactly cutting knife, so this surface trimming pollution discharge pump is simple in structure and practical.

Fig. 2 is pump body structure schematic diagram of the present invention;
Fig. 3 is lower cover structure schematic diagram of the present invention;
Fig. 4 is that impeller of the present invention is faced structural representation;
Fig. 5 is the right TV structure schematic diagram of impeller of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As Figure 1-5, a kind of pollution discharge pump with automatic chopping function, comprise the pump housing 1, lower cover 2 and impeller 3, described lower cover 2 is installed in the pump housing 1 below, described impeller 3 is located in the pump housing 1, described impeller 3 inlet faces are provided with impeller cutting knife 31, described lower cover 2 be provided with impeller cutting knife 31 over against cutting disk 21, between described impeller cutting knife 31 cutting edges and cutting disk 21, be provided with the gap of 0.2mm, described impeller 3 is Single-vane opened impeller, material is cast steel, this impeller is without front shroud, only have one piece of blade to surround a crooked runner, the inlet face of impeller itself is exactly a cutting knife, it is impeller cutting knife,
During operation, sewage is from lower cover 2 intake impellers 3, and when running into prehensile foreign material, the impeller cutting knife 31 of High Rotation Speed will enter impeller and discharge outside cesspool after foreign material chopping with cutting disk 21.
