The main shaft 10 and the stirring paddle 11 are rotatably mounted in the liquid storage tank 1.

[0024] Installation method and operating principle: First, weld multiple horizontal bars 7 and vertical bars 8 to the inner side of the frame plate 3. The horizontal bars 7 and vertical bars 8 are staggered. When welding the horizontal bars 7 and vertical bars 8, it is necessary to avoid the positions of the motor base 12, liquid inlet 15, thermometer port 16, level gauge port 17, observation port, and liquid filling port 19 of the tank cover 2. Then, weld multiple reinforcing plates 4 to the top of the inner wall of the liquid storage tank 1. The distance from the upper surface of the reinforcing plate 4 to the upper surface of the liquid storage tank 1 is the thickness of the frame plate 3. Then, support the frame plate 3 on the reinforcing plates 4. Next, weld the outer perimeter of the frame plate 3 to the inner wall of the liquid storage tank 1. At this time, the upper surfaces of the frame plate 3, horizontal bars 7, and vertical bars 8 are flush with the upper surface of the liquid storage tank 1. The sealing strip 6 is glued to the groove 5. The motor 9 is installed on the motor base 12 of the cover 2. The top of the main shaft 10 is connected to the output shaft of the motor 9 via a coupling. The cover 2 is lifted and then lowered. During this process, the stirring paddle 11 is connected to the main shaft 10 via the connecting sleeve 23. The cover 2 is then supported on the storage tank 1. At this time, the cover 2 is also supported on the frame plate 3, the crossbar 7, and the longitudinal bar 8. Simultaneously, the cover 2 is pressed onto the sealing strip 6. Finally, the cover 2 is fastened to the storage tank 1 with bolts to complete the installation.

The outlet 14 is connected to the processing area via a pump and a pipeline. The return port is connected to the filtration system via a pump and a pipeline. When sedimentation occurs, the motor 9 is started. The motor 9 drives the stirring paddle 11 to rotate via the main shaft 10, thereby agitating the working liquid. This utility model has a reasonable structure. A motor 9 is installed on the upper surface of the cover 2. The output shaft of the motor 9 is connected to the main shaft 10. Several stirring paddles 11 are installed at the bottom of the main shaft 10. Through the stirring mechanism, the working liquid can be stirred to prevent sedimentation. A frame plate 3 is installed at the upper end of the inner wall of the storage tank 1. The frame plate 3 is reinforced by a reinforcing plate 4. A horizontal bar 7 and a vertical bar 8 are installed on the inner side of the frame plate 3. The cover 2 is supported on the frame plate 3, the horizontal bar 7 and the vertical bar 8. A sealing strip 6 is installed on the frame plate 3 through the groove 5. The cover 2 is sealed by the sealing strip 6. On the one hand, it greatly improves the structural strength of the cover 2 and avoids the reduction of the service life of the cover 2 due to the installation of the motor 9.
