Vacuum system of disk pulp washing machine

The utility model provides a vacuum system of disk pulp washing machine, vacuum system includes distribution valve, first vacuum water pump, the logical draught fan of centrifugation and closed pond, the distribution valve includes positive nip and negative pressuren zone, positive nip is connected with the gas outlet that the draught fan is led to in the centrifugation, the negative pressuren zone is connected with the air inlet that the draught fan is led to in the centrifugation, and the negative pressuren zone is connected with closed pond, and the mouth that draws water that seals pond and first vacuum water pump passes through the pipe connection. The utility model discloses a draught fan is led to in the centrifugation, and the negative pressure of having supplyed the negative pressuren zone has reduced equipment because the required height of vacuum water leg, and messenger's equipment is more compact. Be used for shelling the thick liquid with the air of extraction, environmental protection water economy resource more makes the thick liquids concentration after the concentration not shell the thick liquid dilution because of high -pressure squirt.
