[0037] Specifically, the nanofiltration membrane 54 is a nanocomposite membrane. In the filter box 6 , the leachate first passes through a layer of mesh 53 and then is filtered by the nanofiltration membrane 54 . The filtered leachate flows out from another layer of mesh 53 .

[0038] When the driving member 3 moves along the first direction X, it drives the connecting plate 4 to move synchronously, and then drives the nanofiltration membrane 54 and the grid 53 to move along the first direction X through the connecting member 51, the fixing plate 52 and the side plate 55, and finally makes the nanofiltration membrane 54 and the grid 53 move out of the opening 8 or enter the interior of the cleaning box 7 and the filter box 6.

[0041] Among them, when the control telescopic member 23 finally drives the filter assembly 5 to enter the interior of the cleaning box 7, in the cleaning box 7, the corresponding side panel 55 is inserted into the corresponding through groove 91, and the filter assembly 5 is supported by the fixing member 9 on both sides of the interior of the cleaning box 7, so that the cleaning assembly is more stable when cleaning, and prevents the connection between the connecting member 51 and the fixing plate 52 from being damaged due to excessive load when only relying on the connecting member 51 for load.

[0042] It should be noted that the box body here refers to the cleaning box 7 and the filter box 6, that is, the cleaning box 7 and the filter box 6 are both boxes, and the two fixing parts 9 in the same box body refer to the two fixing parts 9 located in the cleaning box 7 and the two fixing parts 9 located in the filter box.

[0043] refer to Figure 1 In an exemplary embodiment, a sealing strip is provided on the periphery of the fixed plate 52. When the nanofiltration membrane 54 and the grid 53 enter the cleaning box 7 and the filter box 6, the periphery of the fixed plate 52 fits with the corresponding opening 8, and the sealing strip is squeezed to ensure that the fixed plate 52 seals the opening 8 to prevent liquid from flowing out of the opening 8 during filtration or cleaning, making it more convenient to use.

[0044] refer to Figure 1 In an exemplary embodiment, a liquid inlet 61 and a liquid outlet 62 are provided on the side of the filter box 6 facing away from the cleaning box 7. The liquid inlet 61 is located on the side of the corresponding filter component 5 facing away from the base 1, and the liquid outlet 62 is located between the corresponding filter component 5 and the base 1.

[0045] Specifically, the garbage leachate enters the interior of the filter box 6 from the liquid inlet 61, then passes through the side grid 53 of the corresponding filter component 5, and then is filtered through the nanofiltration membrane 54, and then flows out from another layer of grid 53. Finally, the filtered leachate is discharged from the liquid outlet 62 and enters the next process.

[0046] refer to Figure 2 and Figure 5In an exemplary embodiment, a liquid discharge port is provided on the side of the cleaning box 7 facing away from the filter box 6, and a slag discharge port is provided on the side of the cleaning box 7 facing the base 1; the processing device may also include a spray plate 71, a fixed pipe 72 and an infusion component 73, wherein the spray plate 71 is arranged inside the cleaning box 7, the spray plate 71 is located on the side of the filter component 5 facing away from the base 1, and a plurality of nozzles are provided on the side of the spray plate 71 facing the filter component 5; the fixed pipe 72 runs through the cleaning box 7, and one end of the fixed pipe 72 located in the cleaning box 7 is connected to the spray plate 71; the infusion component 73 is arranged on the side of the first seat surface facing away from the second seat surface, and is connected to the end of the fixed pipe 72 located outside the cleaning box 7.

[0047] Specifically, the infusion component 73 delivers the cleaning liquid to the fixed tube 72, and then sprays it out from the nozzle of the spray plate 71 to flush the grid 53 and the nanofiltration membrane 54. During flushing, excess solution is discharged from the drain port, and the filter residue is discharged from the residue discharge port.

[0048] Furthermore, in the filter box 6, the filter residue is mostly concentrated on the side of the nanofiltration membrane 54 facing the liquid inlet 61. When this group of filter components 5 enters the cleaning box 7, the driving member 3 drives the filter component 5 to rotate 180°, so that the filter residue is located on the side of the nanofiltration membrane 54 facing the residue discharge port. At this time, it is easier to flush the filter residue down, and the cleaning effect is better.

[0049] In an exemplary embodiment, the infusion component 73 may include a liquid storage tank 731, an electric valve 732 and a water pump 733, wherein the electric valve 732 is arranged on the side of the liquid storage tank 731 away from the base 1, and the electric valve 732 is connected to the liquid storage tank 731 through a connecting pipe; the water pump 733 is arranged on the side of the liquid storage tank 731 away from the base 1, and the water pump 733 is connected to the electric valve 732 and one end of the fixed pipe 72 located outside the cleaning tank 7 through a connecting pipe; the electric valve 732 is an electric three-way valve, and the electric valve 732 has two inlets and one outlet. The liquid storage tank 731 has two cavities inside, and the two inlets correspond to the two cavities one by one, and the inlets are connected to the corresponding cavities through a connecting pipe, and the outlet is connected to the water pump 733 through a connecting pipe.

[0050] Specifically, the liquid in the liquid storage tank 731 can be transported to the fixed pipe 72 by controlling the water pump 733, and then the nanofiltration membrane 54 is flushed by the spray plate 71. The electric three-way valve can control which cavity the liquid is transported to; for example, clean water is stored in one cavity, and cleaning liquid is stored in another cavity. When cleaning, the water pump 733 is turned on, and the electric three-way valve is controlled to connect the fixed pipe 72 with the cavity where the clean water is located for flushing. Then, the electric three-way valve is switched to connect the fixed pipe 72 with the cavity where the cleaning liquid is located, and deep cleaning can be performed. Finally, the electric three-way valve is switched again to connect the fixed pipe 72 with the cavity where the clean water is located to flush the cleaning liquid. In this way, deep cleaning of the nanofiltration membrane 54 and the grid 53 can be achieved.

[0051] Among them, the electric three-way valve and the water pump 733 can be connected to an external power supply or a battery.

[0052] In an exemplary embodiment, a guide plate 11 is provided on the side of the first seat surface facing away from the second seat surface, and a retaining edge 12 opposite to the base 1 in the first direction X is provided on the side of the guide plate 11 facing away from the base 1. The guide plate 11 is located between the slag discharge port and the base 1, and the plane where the guide plate 11 is located has an angle with the plane where the first seat surface is located.

[0053] Specifically, when the slag discharge port is opened for slag discharge, the filter residue falls from the slag discharge port onto the guide plate 11. When the plane where the guide plate 11 is located has an angle with the plane where the first seat surface is located, the guide plate 11 is tilted, and the filter residue is easier to move along the guide plate 11, which is convenient for collecting the filter residue for unified treatment.

[0054] The retaining edge 12 can effectively prevent the filter residue from sliding out of the two opposite sides of the guide plate 11 in the first direction X.
