Pressure screen using the principle

With the development of enterprises, the company introduced a variety of advanced equipment, supporting modern advanced management technology, integrated production, service, production capabilities into the forefront of peers. The following is the use of pressure sieve principle: Pressure sieve is an advanced pulp screening equipment, both for pulp and paper pulp screening system can also be used for paper pulp in the selection. The external rotor internal pressure sieve utilizes the differential pressure inside and outside the screen drum and the positive pressure of the rotor head as the screening power. The pressure pulse generated by the rotation of the rotor serves as a self-cleaning action. The unselected slurry enters the screen body along the tangential direction from the inlet to the pulp mouth. The qualified fibers flow from the outside of the drum into the drum through the mesh holes (sutures) and are discharged through the well tube below the drum drum. The tail of the negative pressure erosion and centrifugal force left sieve drum, discharged from the bottom of the screen body slag discharge tube.

When the pressure sieve is working, the rotor rotates outside the drum and the slurry flows into the drum from the outside of the drum. The direction of the slurry flow is opposite to that of the centrifugal force, and the direction of the impurity removal is the same as that of the centrifugal force, which makes full use of the centrifugal force to make the impurities hardly accessible to the sieve. Keep the sieve open. In addition, the outlet of the outer rotor pressure sieve is located below the concentric circle of the rotor, and the disturbance of the rotor to the slurry is small. The slurry pressure is stable and the pulsation is low. Scope: Suitable for all kinds of flexible packaging, bags of food after the surface stains for cleaning decontamination, removal of oil, grease.
