s2, after the fixed frame (202) is started, outside air is sucked, and sucked air is filtered through the filter screen (205), so that dust is prevented from entering the filtering and separating box (1), and then the dust is sprayed out through the plurality of air nozzles (206), and falling sawdust is blown;

s3, blowing the powdery wood chips, dust and small-particle impurities with light weight and small volume to enable the powdery wood chips, dust and small-particle impurities to fall on one side, away from the guide sloping plate (304), of the partition plate (301), and enabling the wood chip rolls to continuously descend due to large mass and then fall into the guide sloping plate (304) and then slide into the first collection frame (105) to facilitate collection of workers;

s4, when the transmission supporting rod (308) rotates, the transmission bevel gear (310) can be driven to rotate, then the driven bevel gear (311) is driven to rotate through the meshing relation, and then the stirring supporting rod (302) and the auger (303) are driven to rotate, so that filtered water on one side, away from the guide inclined plate (304), of the stirring separation plate (301) is achieved, dust and small particle impurities can be dissolved in water or settled to the bottom of the water, and sawdust can float on the sleeping water surface, so that the separation effect is achieved;

s5, after the stirring support rod (302) and the auger (303) are stirred for a period of time, the motor (306) and the fixing frame (202) are closed, so that filtered water can be kept standing and settled, the water pump (102) is started after the filtering support rod and the auger (303) are kept standing for a period of time, the water pump (102) can pump out water flow in the storage water tank (101) through the water pumping pipe and convey the water flow into the filtering separation tank (1) through the water conveying pipe (103), so that the water surface is continuously raised, then the notch is opened through the discharge mechanism (5), so that the water flow can be discharged, and sawdust floats on the water surface, so the sawdust can be discharged preferentially;

s6, the discharged wood chips and water flow drop onto the filter cotton (402) and are then filtered, so that the wood chips are collected and treated, and the filtered water flow can flow into the storage water tank (101) again through the return pipe (406), so that the resource recycling effect is realized.
