High speed washer is used to remove ink particles, files and other small impurities of the pulp. And it is suitable for washing and concentrating in various domestic and overseas waste recycled pulp, chemical pulp. High speed stock washer has high efficiency impurity prolapse, high efficiency dewatering, less occupied area, large production and clean pulp after washing.
Application:
Uses in waste paper treating system for washing de-inked pulp
The high-speed washing machine sends the pulp into the gap between the polyester mesh and the breast roller through the headbox. The breast roller drives the filter mesh and the flat roller to run at high speed. The pulp is squeezed by the filter mesh and the breast roller at the breast roller. Together with the centrifugal force generated by the high-speed rotation, the pulp can be dehydrated and concentrated. When the pulp reaches the roll with the filter, it is sprayed with washing water, and is replaced by the squeeze and centrifugal force of the filter and the roll again. After washing, the slurry is scraped into the discharge spiral from the roll by a doctor blade. The high-concentration waste water extruded by the pulp at the breast roller and the low-concentration waste water extruded by the squeeze roller are discharged out of the equipment separately to facilitate subsequent waste water treatment. In the above process, because the pulp layer between the filter screen and the roller is very thin, the ink particles, fillers and other fine impurities in the pulp are very little hindered from the pulp layer during the extraction process, so it is easy to accompany the water.
The high speed washing machine is composed of breast roller, couch roller, filter screen, pulp feeding system, pulp discharging system, drainage system, washing system, washing net device, transmission system and frame, hood, etc.
The breast roller is a rubber grooved roller, which can effectively prevent the slurry splash caused by the high-speed operation of the anilox roller.
The couch roller is a rubber couch roll to compensate the uneven squeezing of the slurry produced by the grooved roller. The slurry is stripped to the discharge spiral by a scraper on the couch roll .
The spiral polyester mesh is equipped with guide strips on both sides. , To prevent the net from running off, the function of the hood is to collect the leached water, separate the high-concentration wastewater from the low-concentration wastewater, and prevent the splashing of water from affecting the working environment.
