Gravity Cylinder Thickener
Equipment Introduction:
ZNP series gravity disc concentrators are mainly used for low concentration slurry concentration. This machine is different from the traditional vacuum disc filter, there is no vacuum requirement, so it is not necessary to install the water leg tube installed on the upper floor, which can replace the traditional gravity type round net concentrator.
The central spindle of the filter consists of several rows of filter discs. Each row of discs is composed of 8/10 pieces of fan-shaped plates of the same size and equal area. The sector plates are fixed on the hollow shaft by bolts. When the main shaft is running and the fan-shaped plate is not below the liquid level, there is a liquid level difference between the slurry and the hollow shaft in the tank. Under the action of the liquid level difference, the water in the slurry enters the hollow shaft through the filter screen covering the fan-shaped plate. And the connecting pipe flows out, the slurry is intercepted by the filter net to realize the separation of the slurry water, and the slurry covering the filter net loses the adhesion due to the disappearance of the liquid level difference when the fan-shaped plate is turned out of the liquid surface, under the action of gravity Automatic stripping, stripped high-concentration slurry with the operation of the disc to drive overflow into the slurry pool, to achieve the purpose of concentration .
The equipment is mainly used in low-concentration of mechanical wood pulp, waste paper pulp, mash pulp, bamboo pulp, mash slurry, straw pulp, etc. with low freeness (higher beating degree), short fiber or high pulp concentration. Gravity disc concentrators can be used to increase the concentration. High degree of automation, easy operation, reliable operation, large production capacity, low power consumption and convenient management. The fan-shaped plate is made up of stainless steel orifice plate covered with steel wire mesh, which is convenient to assemble and disassemble, and can filter fine fibers, chemical crystal particles, fillers, etc. in the slurry.

Equipment Feature:
Hood: Made of stainless steel riveted, the appearance is neat.
Tank: The tank supports the transmission and all the components, which are welded by steel plates, including the feeding box, the discharging box and the intermediate tank.
Seal: Sealed at both ends with a packing seal.
Main drive form: It adopts direct-connected suspension reducer to reduce speed and frequency converter to adjust the speed. Users can choose the best speed according to production needs.
Washing device: The nozzle on the spray pipe sprays 0.6MPa of high-pressure water to wash off the adhered slurry on the filter surface, and rinses the filter to obtain the regeneration ability of the filter....
