[0024] refer to Figure 1The first water inlet assembly 3 includes a first drain pipe 32, which is fixedly connected to both sides of the water inlet pipe 4. A first guide pipe 31 is fixedly connected to one side of the first drain pipe 32. One side of the first guide pipe 31 passes through the tank cover 2. A first switch valve 33 is installed on one side of the first drain pipe 32. By setting the first water inlet assembly 3, when water is introduced, the first switch valve 33 on one of the first drain pipes 32 is opened and the first switch valve 33 on the other first drain pipe 32 is closed. At this time, the filtered water enters the first drain pipe 32 with the first switch valve 33 opened through the water inlet pipe 4, and then is injected into the treatment tank 1 through the first guide pipe 31.

[0025] refer to Figure 3 The drainage assembly 6 includes a second water guide pipe 61, which is fixedly connected to both sides of the bottom end of the treatment tank 1. A second drain pipe 62 is fixedly connected to one side of the second water guide pipe 61. Both second drain pipes 62 are fixedly connected to the outlet pipe 5. A second switch valve 63 is installed on one side of the second drain pipe 62. By setting up the drainage assembly 6, when draining, the second switch valve 63 on one second drain pipe 62 is opened and the second switch valve 63 on the other second drain pipe 62 is closed. At this time, the filtered water enters the second drain pipe 62 through the second water guide pipe 61 with the second switch valve 63 open, and then is discharged through the outlet pipe 5.

[0026] refer to Figure 1 The second water inlet assembly 7 includes a third water guide pipe 71. One side of the third water guide pipe 71 is fixedly connected to one side of the flushing nozzle 9.

A booster water pump 75 is installed in the middle of the connecting pipe 74. By setting the second water inlet assembly 7, during flushing, the first switch valve 33 on one third drain pipe 72 is opened, the second switch valve 63 on the other third drain pipe 72 is closed, and the booster water pump 75 is turned on. The water tank 12 enters the third drain pipe 72 and the third water guide pipe 71 through the connecting pipe 74. Then, the filter element 8 is flushed through the flushing nozzle 9 to remove impurities.

[0027] refer to Figure 4The waste removal assembly 10 includes a collection frame 103, which is fixedly connected to both sides of the treatment tank 1 away from the water tank 12. A waste removal pipe 104 is fixedly connected to the bottom end of the collection frame 103. A baffle plate 101 is slidably connected inside the collection frame 103. An electric push rod 102 is fixedly connected to the top end of the baffle plate 101. The electric push rod 102 is fixedly connected to one side of the inside of the water tank 12. Both sides of the inside of the collection frame 103 are fixedly connected to... The guide plate 105 is inclined. By setting the impurity discharge component 10, when the filter element 8 is working, the electric push rod 102 drives the baffle plate 101 to block the collection frame 103 to prevent water from entering the collection frame 103. When cleaning the filter element 8, the electric push rod 102 drives the baffle plate 101 away from the opening of the collection frame 103, and the wastewater after cleaning enters the collection frame 103 and is discharged through the impurity discharge pipe 104 under the action of the guide plate 105.

[0028] refer to Figure 4 Guide rods 11 are fixedly connected to both sides of the top of the baffle plate 101, and one side of the guide rod 11 is slidably connected to the water tank 12. By setting the guide rods 11, the movement of the baffle plate 101 under the action of the electric push rod 102 is more stable.

[0029] Operating principle and advantages: Open the first switch valve 33 on one of the first drainage pipes 32 and close the first switch valve 33 on the other first drainage pipe 32. The liquid to be filtered flows into the first drainage pipe 32 with the switch valve open through the inlet pipe 4, and then through the first guide pipe 31 through the tank cover 2 into the independent chamber on one side of the treatment tank 1. Under pressure, the liquid passes through the filter element 8 in this chamber, and the impurities are intercepted. The filtered liquid flows into the second guide pipe 61 on the corresponding side. At this time, open the second switch valve on the second drainage pipe 62 on that side. Close valve 63 and the second switch valve 63 on the other side. The filtered water will then be discharged from the outlet pipe 5 through the second drain pipe 62, completing one filtration cycle. Meanwhile, the filter element 8 on the other side of the treatment tank 1 is in standby mode. When the working filter element 8 reaches the preset clogging pressure value or working time, the operator closes the first switch valve 33 on the current inlet side and the second switch valve 63 on the drain side, while simultaneously opening the first switch valve 33 and the second switch valve 63 on the other side. This allows the liquid to be filtered to flow into the filter element 8 on the other side for filtration, ensuring the filtration process is complete. Continuously, while the new working filter element 8 is running, a backwashing procedure is initiated for the clogged filter element 8. The third switch valve 73 on the corresponding third drain pipe 72 is opened, the third switch valve 73 on the other side is closed, and the booster water pump 75 in the middle of the connecting pipe 74 is started. Under the booster effect, the clean water in the water tank 12 enters the flushing nozzle 9 through the connecting pipe 74, the third drain pipe 72, and the third water guide pipe 71 in sequence, and is then sprayed out from the flushing nozzle 9 to flush the clogged filter element 8, washing away the impurities from the surface of the filter element. Impurities enter the collection frame 103 on the side of the treatment tank 1 away from the water tank 12 with the water flow. Under the action of the guide plate 105 inclined inside the collection frame 103, the impurities quickly converge towards the discharge pipe 104. When the filter element 8 is working normally, the electric push rod 102 drives the baffle plate 101 to block the opening of the collection frame 103 to prevent water from entering. During backwashing, the electric push rod 102 drives the baffle plate 101 away from the opening of the collection frame 103, so that the sewage containing impurities can smoothly enter the collection frame 103 and be discharged from the device through the discharge pipe 104.
