Overview of pressure screen before wire
Pressure screen before wire adopts the up-flow structure design of pulp at the bottom, heavy slag discharge at the bottom, and light slag discharge at the top, which effectively solves the above problems. Light impurities and air in the pulp naturally rise to the top slag discharge port for discharge, and heavy impurities can settle to the bottom for discharge as soon as they enter the body.
It is used for pre-screening of refined pulp and paper machine in pulping and papermaking system.
Main feature
1. High screening efficiency: Because the slurry enters the sieve along the tangent line at a higher pressure, the fiber and coarse impurities have been separated before the slurry enters the sieve drum under the action of centrifugal force. Qualified fibers quickly pass through the sieve drum depending on the pressure difference between the inlet and outlet of the pulp.
2. Long service life of the screen drum: After the pulp enters the pressure screen, the heavy impurities of the pulp have been separated by the centrifugal effect, so the impact and wear of the impurities on the rotor and the screen drum are reduced. Extend the service life of the screen drum.
3. No clogging when sieving the pulp: the pulp is uniformly sieved from top to bottom without thickening, the impurities are far away from the sieve drum, and the sieve drum is not easy to be blocked.
4. It can replace low-pulse sieve: this machine has low pulse intensity of good pulp, so it will not be disturbed directly on the Internet.
5. The pulp quality is good. The sieve drum is made of stainless steel and the finer sieve slits greatly increase the removal rate of harmful impurities in the good pulp.
6. Low maintenance cost: The spindle adopts advanced mechanical sealing system, which is not easy to be damaged.
