[0028] The rotating roller brush 109 is located at the upper left side of the arc-shaped filter frame 106, the front end of the rotating roller brush 109 is sleeved in the left side of the transmission belt 110, and the middle of the rotating shaft of the motor 102 is sleeved in the right side of the transmission belt 110.

[0029] The filter box 1 is provided with the sundry collecting box 111 at the left side, the sundry collecting box 111 is located directly below the transfer frame 107, the top left side of the transfer frame 107 is hingedly connected with the bottom left side of the cover plate 108, the cover plate 108 is covered on the top of the transfer frame 107, the transfer frame 107 is located directly above the rotating roller brush 109, and the inclined scraper 114 is arranged at the left side of the transfer frame 107.

[0033] In use: First, ensure that the textile wastewater storage tank 2 is connected to the input pipe 105 in the filter box 1 through the pump pipe A202, the pretreatment collecting tank 3 is connected to the output pipe 112 of the filter box 1 through the pump pipe B302, the sundry collecting box 111 is placed directly below the transfer frame 107, and the cover plate 108 is covered on the top of the transfer frame 107. The textile wastewater enters the textile wastewater storage tank 2 through the wastewater transfer pipe A201 and is temporarily stored, when the wastewater needs to be pretreated and filtered, the pump pipe A202 is started, and the wastewater enters the inside of the filter cylinder 103 through the input pipe 105. Filtering and self-cleaning: The motor 102 is started, and the rotating shaft drives the filter drum 103 to rotate clockwise. The wastewater in the filter drum 103 is accelerated by centrifugal force and transferred to the inside of the filter box 1. The wastewater is filtered through the filter drum 103 and the arc-shaped filter frame 106. The fibers, cotton scraps and other impurities are intercepted. The rotating shaft of the motor 102 drives the rotating brush 109 to rotate synchronously through the transmission belt 110. At this time, the rotating brush 109 and the filter drum 103 are in synchronous rotation. The rotating brush 109 first cleans and brushes off the fibers, cotton scraps and other impurities attached to the surface of the filter drum 103. The impurities attached to the rotating brush 109 are scraped off by the inclined scraper 114 and fall into the inside of the transfer frame 107 and are transferred to the impurity collection tank 111 by the transfer frame 107. When the filter drum 103 rotates clockwise, the brush plate frame 104 on the surface of the filter drum 103 penetrates into the gap of the arc-shaped filter frame 106, and the brush plate frame 104 cleans the blockage in the gap of the arc-shaped filter frame 106. When the brush plate frame 104 rotates clockwise and contacts the rotating brush 109 rotating clockwise, the rotating brush 109 directly cleans the impurities attached to the brush plate frame 104. The impurities are also scraped off by the inclined scraper 114 and fall into the inside of the transfer frame 107 and are transferred to the impurity collection tank 111 by the transfer frame 107. Through the above steps, the rotating brush 109 not only cleans the filter drum 103, but also synchronously cleans the arc-shaped filter frame 106 and the brush plate frame 104. The inclined scraper 114 has a preliminary cleaning effect on the rotating brush 109. The inside of the rotating brush 109 in the transfer frame 107 can be cleaned, maintained and inspected by regularly opening the cover plate 108.

[0034] The filtered wastewater is collected at the bottom of the filter box 1, enters the pretreatment collection tank 3 through the output pipe 112 and the pump pipe B302, and is transported to the subsequent processing link through the wastewater transfer pipe B301. The sediment produced during the filtration process is deposited at the bottom of the filter box 1. The inclined sediment discharge valve 113 is opened to quickly discharge the sediment.

[0035] Device shutdown: after the processing is completed, the motor 102, the pump pipe A202 and the pump pipe B302 are closed in turn. The waste discharged from the impurity collection tank 111 and the sediment discharge valve 113 is cleaned to ensure that the device is clean and convenient for next use.
