Stirring, cutting and breaking device of slurry pump

Abstract

The invention relates to a centrifugal fluid conveying pump, in particular to a stirring, cutting and breaking device of a slurry pump. The slurry pump comprises a pump body, a pump shaft and a pump base. An impeller and a stirring and breaking device are sequentially arranged on the pump shaft. The pump body and the pump base are fixedly connected through a front end cover. At least one cleaning water channel is correspondingly arranged at the lower end of the pump body and the upper end of the front end cover. Sealing rings corresponding to the cleaning water channels are arranged between the pump body and the front end cover. Water inlets of the cleaning water channels are connected with a water inlet pipe. Water outlets of the cleaning water channels are connected with high-pressure nozzles. The high-pressure nozzles correspond to the stirring and breaking device. According to the stirring, cutting and breaking device, locked rotating and dry grinding of the slurry pump can be effectively avoided, and the service life of equipment can be prolonged; and the impeller and the stirring and breaking device can cut and break various impurities, including solids, long and soft fibers and the like, contained in sewage, and the phenomena of difficult starting, overloading and dry grinding of the device are eradicated.

Description

technical field [0001] The invention relates to a centrifugal fluid delivery pump, in particular to a stirring, cutting and crushing device for a slurry pump. Background technique [0002] During the sewage treatment process of the slurry pump, the sewage contains various impurities, such as solid particles and long soft fibers, which will affect the startup of the equipment, cause the motor to stall, run abnormally, and even burn the motor; in addition, the sludge The increase in the thickness of the sludge and the reduction of the water volume in the pool will cause the electric pump to start frequently and affect the service life. When the thickness of the sludge exceeds the water inlet of the slurry pump, it will cause the slurry pump to stall and dry grinding. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a slurry pump stirring cutting crushing device, which can effectively prevent ...
