Blocking-free type flexible sewage discharge spiral pump

Abstract

A non-clogging flexible sewage screw pump, the main body is a pump body, a material inlet is arranged at the lower end of the pump body, a material outlet is arranged on one side of the pump body, and an impeller is arranged inside the material inlet, and the shape of the impeller is inverted The shape of the circular frustum, the flow channel of the impeller is set as a single spiral, the width of the flow channel in the impeller is not equidistant, and the bottom end is gradually increased compared with the upper end, and the middle part of the impeller is provided with a mounting hole. A rotating shaft is plugged into the mounting hole, and a driving motor is installed on the top of the rotating shaft. The beneficial effects of the present invention are: the present invention is novel in design and simple in structure. By adopting a single helical flow channel arrangement, it can ensure the high-speed transportation of various solids and high-concentration fluids. The effect is remarkable, investment cost is saved, and energy consumption is reduced. Increase enterprise benefits, easy to promote and use.

Description

technical field [0001] The invention relates to the technical field of pump and valve processing, in particular to a non-clogging flexible sewage screw pump. Background technique [0002] A pump is a machine that transports fluid or pressurizes the fluid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The pump is mainly used to transport water, oil, acid and alkali, emulsion, suspoemulsion and Liquids such as liquid metals can also transport liquid, gas mixtures and liquids containing suspended solids. Generally, water pumps can only transport logistics with fluid as the medium. For solid substances, that transport is not possible. However, at this stage, for The demand for water purification is gradually increasing. The sewage and sludge impurities in the water body are systematically treated by using water pumps and grille pump stations. Therefore, in actual use, not only will the actual eq...

[0002] A pump is a machine that transports fluid or pressurizes the fluid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The pump is mainly used to transport water, oil, acid and alkali, emulsion, suspoemulsion and Liquids such as liquid metals can also transport liquid, gas mixtures and liquids containing suspended solids. Generally, water pumps can only transport logistics with fluid as the medium. For solid substances, that transport is not possible. However, at this stage, for The demand for water purification is gradually increasing. The sewage and sludge impurities in the water body are systematically treated by using water pumps and grille pump stations. Therefore, in actual use, not only will the actual equipment cost be high, but the sewage treatment effect will also be poor. not obvious
