Sewage discharging centrifugal pump capable of preventing clogging by entangled or bunched fibrous materials

Abstract

The invention discloses a sewage discharging centrifugal pump capable of preventing clogging by entangled or bunched fibrous materials. A pump body base is of a U-shaped structure. The pump body baseis evenly provided with a plurality of groups of mounting holes. The pump body base is fixedly installed through the mounting holes. The mounting holes are provided with reinforcing sleeves. The pumpbody base is fixedly installed with a vertically upward motor support and a pump body support. The upper end of the motor support is fixedly mounted with a drive motor. A centrifugal pump body is fixedly installed on the pump body support. An impeller is rotatably arranged in the centrifugal pump body. A plurality of groups of blades are arranged in the annular array on the outer circumference ofthe impeller. An output shaft of the drive motor extends into the centrifugal pump body and is fixedly connected with the impeller. The sewage discharging centrifugal pump filters fibrous materials byarranging a filter screen and cuts entangled fibrous materials with a cutting knife, thereby effectively preventing the fibrous materials from bunching or entanglement in the centrifugal pump and improving use performance and prolong the service life of the centrifugal pump.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a centrifugal pump for sewage discharge that prevents clogging by entangled or bundled fibers. Background technique [0002] Centrifugal pump refers to the pump that transports liquid by the centrifugal force generated when the impeller rotates. The centrifugal pump works by using the impeller to rotate to make the water centrifugally move. Before starting the pump, the pump casing and the suction pipe must be filled with water, and then the motor is started to drive the impeller and the water to rotate at a high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows through the volute pump casing. into the outlet pipe of the water pump. [0003] The traditional centrifugal pump does not treat the sewage in the process of use. The sewage directly enters the centrifugal pump and causes damage to the internal structure of...

AI Technical Summary

Problems solved by technology

[0003] The traditional centrifugal pump does not treat the sewage during the use process. The sewage directly enters the centrifugal pump and causes damage to the internal structure of the pump body, thus affecting the performance and life of the pump body. For the fibers contained in the sewage, When it enters the centrifugal pump, it will be clustered or entangled on the impeller, causing the impeller to fail to rotate normally, and the impeller will break or be damaged under the action of the driving motor.
