The filter cloth 26 can be quickly disassembled from the filter cartridge 25 and replaced by the replacement filter cloth assembly 3, effectively saving the time of replacing the filter cloth 26, and will not affect the actual working efficiency of the filtering device.

[0028] like Figure 3 and Figure 4 As shown, the two disassembly components 2 each include a mounting plate 21, the lower ends of the two mounting plates 21 are fixedly mounted on the left and right sides of the upper end of the filter box 1, the opposite sides of the two mounting plates 21 are rotatably connected with a wire coil 23, the sides of the two mounting plates 21 that are away from each other are rotatably connected with a turning handle 22, the ends of the two turning handles 22 that are close to each other penetrate the mounting plate 21 and are fixedly connected with the sides of the wire coil 23 that are away from each other, the middle parts of the outer walls of the two wire coils 23 are movably wrapped with ropes 24, the ends of the two ropes 24 that are away from the wire coil 23 are fixedly connected with filter cartridges 25, the two filter cartridges 25 are located on opposite sides of the feed pipe 4 and the discharge pipe 5, and the opposite sides of the two filter cartridges 25 are movably provided with filter cloths 26.

[0029] By rotating the handle 22 , the wire coil 23 drives the rope 24 to lift the filter cartridge 25 from the filter box 1 to the outside, so that the staff can handle the filter cartridge 25 .

[0030] like Figure 3 and Figure 5 As shown, four electric telescopic rods 27 are fixedly installed at the top left side and the bottom right side of the filter box 1, and eight adjacent electric telescopic rods 27 are located at the front and rear sides of the outer walls of the feed pipe 4 and the discharge pipe 5.

[0031] The output ends of the eight electric telescopic rods 27 drive the two mounting plates 28 to move closer to or farther from the left and right sides of the filter box 1 , wherein the through grooves can ensure that the position of the feed pipe 4 will not restrict the movement of the mounting plates 28 .

[0032] like Figure 5 As shown, the two mounting plates 28 are rotatably connected to one side away from each other with a toothed disc 29 , and the two mounting plates 28 are rotatably connected to one side away from each other with three gears 210 arranged in a ring, and the outer surfaces of the six gears 210 are meshed with the outer surfaces of the two toothed discs 29 .

[0033] The toothed disc 29 and the gear 210 can be driven to approach or move away from the filter box 1 through the output end of the electric telescopic rod 27 and the second mounting plate 28 .

[0041] Through the regulating action of the regulating rod 37 , the spring 38 can be compressed to pull the regulating rod out from the inner wall of the fixing block 32 , so that the fixing block 32 and the arc-shaped fixing frame 33 can be disassembled to facilitate the replacement and installation of the filter cloth 26 .

[0042] The working principle of the utility model is as follows: when the filter cloth 26 needs to be replaced, the staff starts the eight electric telescopic rods 27, and the output ends of the eight electric telescopic rods 27 drive the two mounting plates 28 to move toward the side close to the filter box 1, so that the ends of the six fixing rods 211 close to each other are separated from the card slot 213, and the staff rotates the toothed disc 29 by the toggle rod 216, so that the toothed disc 29 rotates a certain angle through the slide slot 214 and the limit rod 215, and the six gears 210 drive the fixing rods 211 to rotate a certain angle through the meshing relationship with the toothed disc 29, so that the two filter cartridges 25 are loosened, and the staff rotates The two turning handles 22 drive the wire coiling drum 23 to rotate, and the two wire coiling drums 23 lift the filter cartridge 25 to the outside of the filter box 1 through the rope 24. The staff rotates the two adjusting screws 35 to make the four adjacent protrusions 34 move away from each other, and the four adjacent arc-shaped fixing frames 33 move away from each other, so that the two filter cloths 26 are loosened, and then the two adjusting rods 37 are pulled. The two adjusting rods 37 compress the spring 38 and pull it out from the inner wall of the side of the fixing block 32 that is away from each other, so that the two fixing blocks 32 and the four arc-shaped fixing frames 33 can be removed, and the staff can quickly remove the two filter cloths 26 for replacement.
