The upflow pressure screen for papermaking and pulping is a kind of slurry screening equipment developed by digesting and absorbing the imported prototype in China. The equipment is widely used in the screening of coarse pulp and fine pulp of waste paper pulping and pulp in front of paper machine, and has good working performance.
Principle and features: the pressure screen adopts the upflow structure of slurry feeding at the bottom, heavy slag discharging at the bottom and light slag discharging at the top, which effectively solves the problem of impurity removal. The light impurities and the air in the slurry will naturally rise to the top slag discharge port for discharge, and the heavy impurities will be discharged through the bottom as soon as they enter the machine body. It effectively shortens the residence time of impurities in the screening area, reduces the possibility of impurity circulation and improves the screening efficiency; The wear of rotor and screen drum caused by heavy impurities is prevented, and the service life of the equipment is prolonged.
