Environmental-friendly pump for conveying media with particles and fiber

Abstract

The invention relates to an environmental-friendly pump for conveying media with particles and fiber. The environmental-friendly pump comprises a motor and a pump shaft, wherein the pump shaft passesthrough a pump cover; then, the tail end is positioned in a pump case; the pump case is connected with the base; an impeller is arranged on the pump shaft; a front cover plate and a back cover plate are arranged on the impeller; the front cover plate is right aligned with the base; an opening ring is arranged on the base; a blade on the impeller is projected out the front cover plate and is aligned with the end surface of the base side for a certain distance; the part, projected out of the front cover plate, of the blade is positioned in the opening ring. The manufacturing and processing difficulty of the pump and the impeller weight are reduced by improvement on the basic structure of a submersible sewage pump, so that the non-blockage performance and non-overload performance of the pumpare improved.

Description

technical field [0001] The invention relates to an environmentally friendly pump suitable for transporting particles and fibers, in particular to a non-clogging impeller mainly suitable for transporting solids with entangled long fibers and large particles. The utility model belongs to the technical field of slurry and sewage conveying equipment. Background technique [0002] At present, when transporting sewage and sewage media, the pump is often clogged due to solid impurities such as long fibers such as long plastic fibers, hemp fibers and large particles in the medium, which affects the passing performance and operating efficiency of the pump and reduces the pump capacity. The reliability and service life of the impeller; the fibers wound on the impeller not only reduce the effective flow area of ​​the pump and cause blockage, but also need to be shut down frequently for processing and frequent maintenance, which affects work efficiency and delays industrial production. ...

Problems solved by technology

Although this type has a cutting knife, it increases the power consumption on the other hand, and the efficiency is low. Moreover, with the addition of a cutting knife, the inlet flow area is reduced to a certain extent, and the flow rate is reduced.

After searching, the published patent "An Anti-blocking Submersible Sewage Pump" (Application No.: 201010500477.8), the main cutting device of the sewage pump includes impeller, pump cover, convex ring, impeller cover, moving blade, fixed blade, groove, The working principle of this patent is similar to that of the previous search patent, both of which have cutting knives, which have a strong ability to pass you through, but will consume some power of the impeller shaft, and the motor is easily overloaded and the efficiency is low
