AI Technical Summary

Technical Problem

During the cleaning process of existing pumps, impurities and dirt can easily bypass the agitator structure, resulting in a weak agitator structure that cannot effectively remove impurities from the pump chamber, causing blockages and hygiene problems.

Method used

Design a pump with an inner casing having a crushing channel, the flow port diameter being smaller than the inner diameter of the receiving cavity, and blades located inside the crushing channel. Impurities carried by the fluid are crushed in the crushing channel, enhancing the crushing capacity. Furthermore, the path length of the fluid in the crushing channel is increased through the cooperation of the barrier ring and the impeller.

Benefits of technology

It effectively improves the pump's ability to break up impurities, reduces the risk of clogging, and enhances the pump's cleaning effect and hygiene safety.

Abstract

The application discloses a pump, comprising a pump body and a driving part, the driving part is installed with the pump body, the pump body has a containing cavity, the pump comprises an impeller, a blade and a pump shaft, the impeller and the blade are fixed with the pump shaft, the pump comprises an inner cover, the inner cover is integrated with or connected with an inlet part of the pump or the impeller, the inner cover has a crushing flow channel, the inlet part has an inlet flow channel, the crushing flow channel is communicated with the inlet flow channel, the flow passage diameter of the crushing flow channel is smaller than the inner diameter of the containing cavity, and the blade is located in the crushing flow channel. The pump of the above technical scheme, the blade is located in the crushing flow channel of the inner cover, the fluid flows into the crushing flow channel from the inlet flow channel, the impurities entering the crushing flow channel are not easy to bypass the blade because the flow passage diameter of the crushing flow channel is smaller than the inner diameter of the containing cavity, so that the impurities carried by the fluid are more easily crushed in the crushing flow channel, and the crushing capacity of the pump on the impurities is improved.
