[0034] A plurality of filter membranes 13 are arranged inside the cylinder 1, and sewage can be effectively filtered and treated through the filter membranes 13. The sealing assembly includes a limiting plate 19, and the outer portion of the limiting plate 19 is slidably connected to the inner wall of the top cover 5, so that the limiting plate 19 will be restricted by the top cover 5. A sealing gasket 7 is fixedly connected to the bottom of the limiting plate 19, and the bottom of the sealing gasket 7 fits with the top of the cylinder 1. When the device is closed, the sealing gasket 7 can tightly seal the interior of the cylinder 1 to prevent water from overflowing. The sealing gasket 7 is a rubber gasket with good flexibility and sealing properties. The top of the limiting plate 19 is fixedly connected with a shell sleeve 8 on all sides.

[0035] refer to Figure 3 and Figure 4A spring 9 is arranged inside the shell 8, and a limiting block 10 is slidably connected to the inner wall of the shell 8, and the shell 8 can be restricted by the limiting block 10. One end of the spring 9 is fixedly connected to one side of the limiting block 10, and the other end of the spring 9 is fixedly connected to the inner wall of one side of the shell 8. When the limiting block 10 moves, the spring 9 can be squeezed to make the spring 9 deform and generate elastic potential energy, so as to provide rebound force later. A sliding column 11 is fixedly connected to the top of the limiting block 10, and the outer side of the sliding column 11 is slidably connected to the top of the shell 8. The limiting block 10 can be pushed by sliding the sliding column 11 on the top of the shell 8. The top of the sliding column 11 is fixedly connected to the top inner wall of the top cover 5, so that the limiting plate 19 can be connected to the top cover 5, thereby improving the stability effect.

[0036] refer to Figure 3 and Figure 5 , control rods 12 are slidably connected to both sides of the outer top of the cylinder 1, and the outer part of the control rod 12 is slidably connected to the inner wall of the cylinder 1, so that the control rod 12 can slide stably, and one side of the outer part of the control rod 12 is arc-shaped, and extension rods 14 are fixedly connected to both sides of the bottom of the top cover 5, and the outer part of the extension rod 14 is slidably connected to the top of the cylinder 1, and the top cover 5 and the cylinder 1 can be connected by the extension rod 14, and the outer part of the control rod 12 is engaged with the through hole of the extension rod 14, and the extension rod 14 can be fixed by the control rod 12, so that the top cover 5 is fixed to the top of the cylinder 1.

[0037] The top of the control rod 12 is rotatably connected to a rotating rod 15, and when the control rod 12 moves, the rotating rod 15 can be driven to rotate. The other end of the rotating rod 15 is rotatably connected to a sliding block 16. When the rotating rod 15 rotates, the sliding block 16 can be pushed to move. The outside of the sliding block 16 is slidably connected to the inner wall of the cylinder 1, and the sliding block 16 can be stabilized by the cylinder 1. Fixed rods 17 are fixedly connected to the inside of the top of the cylinder 1 on both sides. The outside of the fixed rod 17 is sleeved with a spring 2 18, and the spring 2 18 is limited by the fixed rod 17. The through hole of the sliding block 16 is slidably connected to the outside of the fixed rod 17, which further stabilizes the sliding block 16. One end of the spring 2 18 is fixedly connected to one side of the sliding block 16, and the other end of the spring 2 18 is fixedly connected to the inner wall of one side of the cylinder 1. When the sliding block 16 moves, the spring 2 18 can be squeezed.

[0038] Working principle: when the equipment needs to be used, sewage to be filtered is added from the top of the water inlet pipe 6, and the water will enter the cylinder 1 and be filtered by the microfiltration membrane 13. The designed water production pipe 1 2 and the water production pipe 2 3 are connected to multiple filter membranes 13. At this time, the pressure inside the filter membrane 13 can be balanced to avoid pressure difference reaction, which can achieve better filtering effect. When the cylinder 1 needs to be opened, the control rod 12 is pulled, and the rotating rod 15 can be driven to rotate under the pulling of the control rod 12. The rotation of the rotating rod 15 can drive the sliding block 16 to move. The movement of the sliding block 16 can squeeze the spring 2 18, so that the spring 2 18 is deformed to generate elastic potential energy. At this time, the control rod 12 can be pulled out of the through hole of the extension rod 14, and the top cover 5 can be removed to filter the inside of the cylinder 1. The membrane 13 is replaced to ensure the filtering effect. When it needs to be closed, the extension rod 14 is inserted into the top of the cylinder 1. At this time, the extension rod 14 can push the control rod 12, so that the control rod 12 will drive the rotating rod 15 to rotate so that the fixing rod 17 squeezes the spring 2 18. When the extension rod 14 moves to a suitable position, the spring 2 18 will rebound so that the sliding block 16 is pushed and drives the rotating rod 15 to rotate, so that the control rod 12 is reset to engage the through hole of the extension rod 14 so that the top cover 5 is fixed and the installation is completed. During the installation process, the top cover 5 will push the limiting plate 19 to drive the sealing gasket 7 to press against the top of the cylinder 1. At this time, the spring 1 9 inside the shell 8 will be continuously compressed, so that the sealing gasket 7 can fit closely to the top of the cylinder 1, thereby improving the sealing effect and preventing sewage from leaking from the top of the cylinder 1.
