The Couch Roller Inside High Speed Washer For Waste Paper Pulp Cleaning

working principle

The high-speed pulp washing machine sends the pulp into the gap between the polyester net and the breast roll through the headbox, and the breast roll drives the net and couch roll to run at high speed, and the pulp is squeezed by the net and the breast roll at the breast roll The combined action of force and centrifugal force generated by high-speed operation makes the pulp dehydrated and washed. When the pulp reaches the roller with the wire, it is squeezed by the wire and couch roller again and further dehydrated by the centrifugal force, and then the pulp is removed from the screen by the scraper. Scrape into the discharge spiral on the couch roller. In the above process, because the pulp layer between the mesh and the roller is very thin, the ink particles, fillers and other fine impurities in the pulp are rarely hindered by the pulp layer during the detachment process, so they are easily mixed with water. come out.

The main structure

The equipment is composed of breast roll, couch roll, filter screen, pulp inlet system, pulp outlet system, drainage system, spray system, transmission system, frame, machine cover, etc. Among them, the breast roll is a rubber grooved roll, which can effectively prevent the slurry splash caused by the high-speed operation of the screen roll. The couch roll is a rubber flat roll, which supplements the uneven extrusion of the pulp produced by the grooved roll; the scraper is used on the couch roll to peel off the washed pulp to the discharge spiral; the filter screen is a polyester net with The guide bar prevents the net from running off; the function of the hood is to collect the water that escapes, preventing the water from splashing and affecting the working environment.

According to the drawings provided by customers or our professional meticulous rigorous drawing, advanced processing technology and equipment are used, and the rubber has good elasticity, moisture resistance, heat resistance, acid and alkali resistance and corrosion resistance, and the surface has accurate and uniform hardness. The maximum tolerance of hardness should be within the allowable range, and the aging resistance is good. Ensure that the rubber roller can perfectly fit the customer's paper machine, extend the service life, save costs for customers, and create more revenue.
