Main Structure:
This machine is mainly composed of disc shaft, trough, hood, main transmission device, etc.
1) Fan-shaped plate: adopts a perforated plate structure, covered with a stainless steel filter screen, and the fan-shaped plate and the hollow main shaft are connected by bolts.
2) Hood: welded by steel plate
3) Tank body: The tank body supports the transmission device and all parts, and is welded by steel plates, including the feed box, the discharge box and the middle tank.
4) Both ends are sealed with rubber packing
5) The main drive form: the direct-connected suspension reducer is used for speed reduction, and the inverter speed is adjusted. The user can choose the best speed according to the production needs.
Screen washing device: 0.5-0.7Mpa high-pressure water sprayed from the nozzle on the water spray pipe to wash off the slurry adhering on the surface of the filter screen, and the filter screen is washed to obtain the regeneration capacity of the filter screen.
Advantage:
For mechanical wood pulp, waste paper pulp, reed pulp, bamboo pulp, bagasse pulp, straw pulp, etc. with low freeness (higher beating degree), short fiber or high pulp concentration, the gravity disc type can be used at low concentration. The thickener is used to increase the concentration. The machine is highly automated, easy to operate, reliable in operation, large in production capacity, low in power consumption, easy to manage, and the fan-shaped plate is welded by stainless steel, which is convenient to assemble and disassemble, and can filter small fibers and chemicals,solute, filler, etc.
Work Principle :
The central spindle of the filter is composed of several filter discs. Each disc is composed of 8-10 fan-shaped plates with the same size and equal area. The fan-shaped plates are fixed on the hollow shaft by bolts. The hollow shaft is connected with the fan-shaped plates. In the working process, with the rotation of the main shaft, when the fan-shaped plate is submerged below the liquid level, there is a liquid level difference between the inside and outside of the fan-shaped plate. Under the action of the liquid level difference, the water in the slurry passes through the covering The filter screen outside the fan-shaped plate enters the hollow shaft and flows out through the hollow shaft and the pipe. The slurry is intercepted by the filter screen to achieve slurry-water separation. When the slurry covering the filter screen turns out of the liquid surface on the fan-shaped plate, due to the liquid level The difference disappears and the adhesion is lost, and it is automatically peeled under the action of gravity. The peeled high-concentration slurry will overflow into the slurry outlet along with the operation of the disk to achieve the purpose of concentration.
