Abstract

The invention discloses a medium consistency pump and a conveying system thereof. The medium consistency pump includes a pump body. The front end of the conveying impeller is provided with a turbulence generator, and the front end of the turbulence generator forms a flow. The gaseous separation zone is formed at the top of the turbulence generator, and the pumping zone is formed between the impeller of the conveying impeller and the chamber of the pump body. A degassing area is formed between the side wall of the pump body and the chamber side wall of the pump body, and a fiber recovery area is formed at the center of the back side of the conveying impeller; it also includes a conveying system, which consists of a medium-consistency standpipe, a medium-consistency pump, and a vacuum pump steam. It consists of liquid separator, electrical controller and sealed cooling water inlet pipe. The present invention can fluidize and degas the medium-consistency slurry by setting a specific medium-consistency slurry pump, thereby improving the conveying capacity of the medium-consistency slurry, and in conjunction with a specific conveying system, the liquid level in the medium-consistency standpipe can be adjusted. Perform auto-adjusting dilutions.

Description

technical field [0001] The invention relates to the technical field of slurry transportation, in particular to a medium-consistency slurry pump and a transportation system thereof. Background technique [0002] During the production process of medium-consistency bleaching, due to the unstable flow or concentration of incoming pulp, the liquid level of the medium-consistency riser often fluctuates, which is unfavorable for the subsequent production process. At present, the frequency of the motor is adjusted according to the change of the liquid level to change the speed of the medium-consistency slurry pump, so as to achieve the purpose of adjusting the flow and stabilizing the liquid level of the riser. However, when the rotation speed is reduced to a certain value, due to the high air content, high viscosity and large conveying resistance of the medium-concentration slurry, it is easy to be unable to pump. SUMMARY OF THE INVENTION [0003] The purpose of the present inve...
