[0026] Figures 1 to 6 The sewage filtration device shown includes a drain tank 1, a filter screen 3 inside the drain tank 1, the filter screen 3 filters impurities in the sewage that enters the drain tank 1, and a number of fastening screws 4 are provided at the upper cover plate of the drain tank 1 to fix the filter screen 3 inside the drain tank 1. A sewage discharge pipe 5 is connected to one side of the drain tank 1 by a connecting bolt 7 flange, and a sewage main pipe 6 is connected to the drain tank 1 by a connecting bolt 7 flange.

[0027] Figures 1 to 6 Before sewage discharge, the equipment's sewage discharge pipe 5 and main sewage discharge pipe 6 are connected to the drainage tank 1 via flanges using connecting bolts 7. Then, the cover of the sewage discharge pipe is opened, and the filter screen 3 is placed inside the drainage tank 1. The cover of the drainage tank 1 is then fixed using fastening screws 4. The filter screen 3 is then fixed inside the drainage tank 1. Sewage from the equipment's sewage discharge pipe 5 then reaches the drainage tank 1, where it is filtered by the filter screen 3 to remove impurities and foam particles. The sewage after filtering through the filter screen 3 then reaches the main drainage pipe, and finally, the sewage is discharged into the water tank for treatment.

[0028] Figures 1 to 6The drain tank 1 shown is equipped with a sealing ring 2 near the cover plate to improve the sealing performance of the upper part of the drain tank 1. By fixing the sealing ring 2 to the upper part of the drain tank 1 and then fixing the cover plate with the fastening screws 4, the connection between the cover plate and the drain tank 1 is sealed, preventing sewage from leaking through the gap between the drain tank 1 and the cover plate, thereby improving the performance of the drain tank 1. Metal gaskets 8 are provided at the flange connections of the drain tank 1, the equipment drain pipe 5, and the main drain pipe. The use of metal gaskets 8 at the flange connections of the drain tank 1, the equipment drain pipe 5, and the main drain pipe effectively improves the sealing performance and prevents leakage. The metal gaskets 8 are high-temperature resistant and corrosion-resistant, adaptable to harsh environments, and can withstand high pressure and vibration, maintaining the stability of the connection.

[0029] Figures 1 to 6 The drain tank 1 shown is equipped with a cleaning device 9 at the top cover plate. The cleaning device 9 includes a motor 91, a rotating rod 92, a connecting plate 93, and a cleaning brush 94. The motor 91 is located at the top of the cover plate of the drain tank 1, the rotating rod 92 is located at the output end of the motor 91, several connecting plates 93 are located on the surface of the rotating rod 92, and the cleaning brush 94 is located on the side of the connecting plate 93 away from the rotating rod 92. The size of the cleaning brush 94 is adapted to the size of the filter tank.

[0030] Figures 1 to 6 Before connecting the cover plate to the drain tank 1, the motor 91 is fixed to the cover plate, and the output end of the motor 91 is fixed to the rotating rod 92 through a coupling. After the cover plate and the drain tank 1 are fixed with fastening bolts, the connecting plate 93 fixed on the rotating rod 92 and the cleaning brush 94 fixed on the side of the connecting plate 93 away from the rotating rod 92 are located inside the filter screen 3, and the bristles of the cleaning brush 94 are in contact with the inner wall of the filter screen 3. When the filter screen 3 is in use, the motor 91 at the upper cover plate of the drain tank 1 can be started, so that the motor 91 drives the rotating rod 92 to rotate. Then, the connecting plate 93 fixed on one side of the rotating rod 92 drives the cleaning brush 94 to clean the impurities and foam particles adhering to the filter holes on the surface of the filter screen 3. By using the cleaning device 9, the impurities and foam particles adhering to the filter holes on the surface of the filter screen 3 can be cleaned, reducing the frequency of manual cleaning, ensuring the long-term efficient operation of the filter screen 3, avoiding the filter screen 3 from being affected by the clogging of the sediment, thereby improving the use effect of the filter screen 3.

[0031] Figures 1 to 6The connecting plate 93 shown has several through holes 95 on one side to reduce its surface size. By creating these through holes 95, the surface size of the connecting plate 93 is reduced, thus decreasing the rotational resistance within the water-filled filter screen 3. This allows the connecting rod to more easily rotate the cleaning brush 94. A reinforcing plate 96 is provided on the side of the connecting plate 93 near the cleaning brush 94. One side of the reinforcing plate 96 connects to the cleaning brush 94 to enhance the connection strength between the reinforcing plate 96 and the cleaning brush 94. By fixing the reinforcing plate 96 to the cleaning brush 94 and the connecting plate 93, the connection strength between the connecting plate 93 and the cleaning brush 94 is improved, preventing deformation at the connection point and ensuring the continued use of the cleaning brush 94.

[0032] Figures 1 to 6 A vibration assembly 97 is provided on one side of the rotating rod 92, which causes the filter screen 3 to vibrate, thereby loosening the debris adhering to the surface of the filter screen 3. The vibration assembly 97 includes an elastic rod 971, a striking ball 972, and several vibration blocks 973. The elastic rod 971 is located on one side of the rotating rod 92, the striking ball 972 is located on the side of the elastic rod 971 away from the rotating rod 92, and the several vibration blocks 973 are located on the inner wall of the filter screen 3 to be struck and vibrated by the striking ball 972. When the rotating rod 92 rotates, the elastic rod 971 fixed on the surface of the rotating rod 92 is rotated along with it. Then, the striking ball 972 fixed on one side of the rotating rod 92 strikes several vibrating blocks 973 fixed inside the filter screen 3, causing the vibrating blocks 973 to vibrate. The vibrating blocks 973 transmit the vibration to the filter screen 3, causing the filter screen 3 to vibrate. This loosens the debris adhering to the surface of the filter screen 3, making it easier for the cleaning brush 94 to clean the debris adhering to the surface of the filter screen 3. When the striking ball 972 passes the vibrating block 973, the elastic rod 971 deforms, causing the striking ball 972 to pass the vibrating block 973. Then, the elastic rod 971 drives the striking ball 972 to reset, so that the striking ball 972 can strike and vibrate the next vibrating block 973.

[0033] Working principle: Before sewage discharge, the equipment's sewage discharge pipe 5 and main sewage discharge pipe 6 are connected to the drainage tank 1 via connecting bolts 7. Then, the cover plate of the sewage discharge pipe is opened, and the filter screen 3 is placed inside the drainage tank 1. The cover plate of the drainage tank 1 is then fixed with fastening screws 4. The filter screen 3 is then fixed inside the drainage tank 1. Sewage from the equipment's sewage discharge pipe 5 reaches the drainage tank 1 and is filtered by the filter screen 3, removing impurities and foam particles. The sewage after filtering through the filter screen 3 then reaches the main sewage discharge pipe and is finally discharged into the water tank for treatment.

[0034] Before connecting the cover plate to the drain tank 1, fix the motor 91 to the cover plate, and fix the rotating rod 92 to the output end of the motor 91 through a coupling. After the cover plate and the drain tank 1 are fixed with fastening bolts, the connecting plate 93 fixed on the rotating rod 92 and the cleaning brush 94 fixed on the side of the connecting plate 93 away from the rotating rod 92 are located inside the filter screen 3, and the bristles of the cleaning brush 94 are in contact with the inner wall of the filter screen 3. When the filter screen 3 is in use, the motor 91 at the upper cover plate of the drain tank 1 can be started, so that the motor 91 drives the rotating rod 92 to rotate. Then, the connecting plate 93 fixed on one side of the rotating rod 92 drives the cleaning brush 94 to clean the impurities and foam particles adhering to the filter holes on the surface of the filter screen 3. By using the cleaning device 9, the impurities and foam particles adhering to the filter holes on the surface of the filter screen 3 can be cleaned, reducing the frequency of manual cleaning, ensuring the long-term efficient operation of the filter screen 3, avoiding the filter screen 3 from being affected by the clogging of the sediment, thereby improving the use effect of the filter screen 3.
