[0004] Through the arrangement of four rotating rollers, four cleaning sleeves, two cleaning motors, four first gears and two second gears, the device can adsorb and clean the fiber impurities in the wastewater. Through the belt transmission mechanism, a plurality of first hooks, a plurality of second hooks and a collection box, the fiber impurities adsorbed on the four cleaning sleeves can be cleaned and collected. Through two second filters, two cleaning plates, two cleaning cylinders and a discharge pipe, the fiber impurities in the wastewater can be filtered and cleaned for the second time. However, when the cleaning cylinder drives the cleaning plate to clean the second filter screen, residual fibers will also fall on the second filter screen behind the cleaning plate. When the cleaning plate returns to its original position, this part of the residual fibers cannot be removed. Therefore, the device cannot continuously treat the wastewater and can only treat the wastewater after the cleaning plate returns to its original position. Content of the Utility Model
