Spin filter can recover the fine fibers produced in the papermaking process, the air-floatation water from air floatation machine, cooking black liquor, white water under the mesh, backwater from disc filter, whitewater from the vacuum suction box through the filtration and achieve the purpose of reuse.
This product consists of shell like a pot cover, sling type filter, six specially designed inlet pipes, supporting cylinder, intermittent cleaning spray pipe, and PLC control system.
The spin filter by utilizing the impact force of the incoming water, we drive the endless rotation of the belt filter to generate centrifugal force, thereby achieving the separation of water and impurities. During the paper making process, liquid that needs to be filtered is generated and sprayed onto the filter screen through a special nozzle installed on a fixed spray pipe on the main pipe. The spray pipe and filter screen are arranged in parallel. Several specially designed nozzles on the spray pipe evenly spray liquid onto the surface of the filter under very low pressure (less than 0.06 Mpa is also acceptable). The nozzle design at different angles creates an intersecting impact force on the sprayed water, which drives the filter to rotate. The water passing through the filter is collected and discharged from the filtrate outlet at the bottom of the equipment. The remaining solid suspended solids slide along certain angle of the filter to the center of the equipment and enter the collection tank.
