[0006] In use, open the second valve on the water inlet pipe and the water pump, and close the third valve on the third drain pipe, the water pump pumps the sewage discharged by the sweater during the fulling or washing process into the second box through the water inlet pipe, the sewage is filtered through the filter screen on the filter screen plate, the short hair fibers remain on the filter screen to form a fiber layer, the filtered sewage rises and is discharged into the first box through the second drain pipe, open the first valve on the first box, and discharge the filtered sewage to the subsequent equipment through the first drain pipe for treatment, when the filtration is completed, close the water pump and the second valve, and open the third valve, the water in the upper part of the second water tank will backflush the filter screen, the fiber layer on the filter screen is flushed down and enters the filter sleeve with the sewage through the third drain pipe, the sewage enters the first box through the filter sleeve, and the fiber layer is collected in the filter sleeve, so that the fiber layer on the filter screen can be automatically cleaned every time the sewage is filtered, thereby ensuring the filtering effect next time, when the fiber layer collected in the filter sleeve is relatively large, the sealing cover on the maintenance pipe can be removed, and the fiber layer in the filter sleeve is cleaned.

[0007] Further, in order to control more conveniently, the controller, the first valve, the second valve and the third valve are all electromagnetic control valves, and the controller is electrically connected with the first valve, the second valve, the third valve and the water pump.

[0008] The wastewater filtering device for sweater production has the beneficial effects that the sewage is filtered through the filter screen, the short hair fibers remain on the filter screen to form a fiber layer, the filter screen can be backflushed by the residual sewage in the second box when the filtration is completed, and the fiber layer can be collected through the filter sleeve, so that the fiber layer on the filter screen can be automatically cleaned every time the sewage is filtered, and the filtering effect next time is ensured.
