In above-mentioned novel sewage pump, the upper surface of described annular convex two is provided with annular groove, and described annular groove is embedded with sealing ring, and the upper surface of described sealing ring is resisted against in the lower wall of described annular convex one.Sealing ring is embedded in annular groove, makes annular convex one be formed with annular convex two and seals, and makes sealing ring have good locating effect and make upper pump casing and lower pump body have good sealing effectiveness.
In above-mentioned novel sewage pump, the lateral wall of described feeding roller is provided with spiral slot.By arranging the feeding roller with spiral slot, make the good advantage of pollution discharge capability of this novel sewage pump.
In above-mentioned novel sewage pump, the angle of the helical angle of described spiral slot is 35 ° to 50 °.Adopt above-mentioned setting, make spiral slot have the advantage that conveying capacity is stronger.
Compared with prior art, this novel sewage pump has the advantage that
1, leant by the annular convex two of the annular convex one of upper pump casing with lower pump body, making upper pump casing and lower pump body be fixedly connected with by bolt, enable the pump housing to dismantle, it is simple to the cleaning of the cavity of the pump housing；
2, owing to the middle part of the pump housing is protruded outward and is fixed with feeding roller in rotating shaft, this novel sewage pump is made to have good pollution discharge capability；
3, sealing ring is embedded in annular groove, makes annular convex one be formed with annular convex two and seals, and makes sealing ring have good locating effect and make upper pump casing and lower pump body have good sealing effectiveness；
4, by arranging the feeding roller with spiral slot, the good advantage of pollution discharge capability of this novel sewage pump is made.
