The high-speed washing machine sends the slurry into the gap between the polyester mesh and the breast roller through the headbox. The breast roller drives the mesh and the flat roller to run at high speed. The slurry is squeezed by the mesh and the breast roller at the breast roller. The combined action of the centrifugal force and the centrifugal force generated by the high-speed operation enables the slurry to be dehydrated and washed. When the slurry reaches the roll with the web, it is again dewatered by the squeezing and centrifugal force of the web and the flat roller, and then the slurry is removed from the Scrape into and out of the spiral on the roll. In the above process, because the slurry layer between the net and the roller is very thin, the ink particles, fillers and other small impurities in the slurry are rarely hindered from the slurry layer during the extraction process, so it is easy to get out together with the water.
The equipment is composed of breast roller, flat roller, filter screen, pulp feeding system, pulp discharging system, drainage system, spray system, transmission system and frame, hood, etc. Among them, the breast roller is a rubber grooved roller, which can effectively prevent the slurry splash caused by the high-speed operation of the mesh roller. The flat roller is a rubber flat roller to compensate for the uneven squeezing of the slurry produced by the grooved roller; the slurry is peeled off to the discharge spiral by a scraper on the flat roller; the filter screen is a polyester mesh with both sides The guide bar prevents the net from running off; the function of the hood is to collect the escaping water and prevent the water from splashing and affecting the working environment .
This equipment has extremely high removal efficiency for fine impurities such as ink ions and fillers in the slurry. It can be widely used in the washing and concentration of waste newsprint recycled pulp, waste account paper recycled pulp and waste book paper recycled pulp
