A connecting frame 35 is fixedly connected to one side of the first guide plate 30, and a plurality of floating balls 36 are fixedly connected to the other end of the connecting frame 35; The first guide plate 30 realizes adaptive adjustment of the water level in the dust removal box 1 through the buoyancy of the float 36 and the thrust of the limit spring 34 .

[0021] It should be noted that the width of the first guide plate 30 and the positioning guide block 33 is the same as the width of the dust removal box 1, and both sides of the first guide plate 30 and the positioning guide block 33 are made of rubber strip material, so that the first guide plate 30 and the positioning guide block 33 are closely attached to the inner wall of the dust removal box 1 to prevent gas leakage and affect the gas guiding effect; The front end of the first guide plate 30 is attached to the front side of the dust removal box 1 .

[0022] In the present invention, preferably, the guiding mechanism 3 further includes a limiting column 32, which is fixed in a slide groove provided in the dust removal box 1; The micro motor 39 is fixed to one side of one of the limiting rods 38 and the output end is fixed to the second guide plate 37 .

[0023] It should be noted that a waterproof box is fixedly installed on one side of one of the limiting rods 38, and the micro motor 39 is placed inside the waterproof box to prevent the micro motor 39 from being flooded and conducting electricity.

[0024] In the present invention, preferably, the surface of the limiting post 32 is slidably connected to the slider 31, and the limiting spring 34 is sleeved on the limiting post 32; The output end of the micro motor 39 passes through and is rotatably connected to the middle portion of one side of the limiting rod 38 .

[0029] During the implementation process, the traction fan in the collection pipe 2 rotates to suck dust and gas into the dust removal box 1. The gas and dust are guided by the first guide plate 30 and enter between the second guide plate 37 and the first guide plate 30 from the bottom of the first guide plate 30. They are transported upward along the second guide plate 37 and finally exit between the second guide plate 37 and the positioning guide block 33. During the dust guidance flow, the dust contacts the clean water in the dust removal box 1 and settles on the water surface.

The first guide plate 30 moves the slider 31 upward along the slide groove and the limit column 32 inside the dust removal box 1. The first guide plate 30 , the positioning guide block 33 , and the second guide plate 37 can be automatically adjusted according to the water level to ensure the dust filtering effect.

[0034] During the implementation process, the air holes in the middle of the partition plate 6 draw the gas and are sucked into the fan 8 through the guide plate 40 and discharged through the exhaust pipe 9. When the inclination angle of the guide plate 40 needs to be changed; Rotate the rotating disk 43, and the rotating disk 43 rotates along the middle of the positioning disk 42 with the connecting shaft 41 and the guide plate 40, thereby adjusting the inclination angle of the guide plate 40, and pass the limit pin 44 through the positioning holes of the rotating disk 43 and the positioning disk 42 to lock the rotating disk 43, so that the guide plate 40 is easier to rotate and adjust the inclination angle to control the efficiency of the gas flow.

[0035] Example 3 In the present invention, preferably, a cleaning mechanism 5 is provided on the other side of the dust removal box 1 for realizing the circulation of clean water in the dust removal box 1 .

[0036] In the present invention, preferably, the cleaning mechanism 5 includes a servo motor 50, which is fixed to one side of the outside of the dust removal box 1 and has a transmission shaft 51 fixed in the middle thereof, which is rotatably connected to the middle of the dust removal box 1; The impeller 52 is fixed to the middle portion of the transmission shaft 51 and is disposed on one side of the dust removal box 1 .

[0039] During the implementation process, a servo motor 50 is provided. The output end of the servo motor 50 drives a transmission shaft 51 to rotate along the middle of the dust removal box 1. The rotation of the transmission shaft 51 drives an impeller 52 to rotate. The rotation of the impeller 52 pulls the clean water in the dust removal box 1, causing the clean water to circulate and filter dust through the dustproof net 56, thereby maintaining the filtering effect of the clean water and making the filtered water flowing back have a better filtering effect. As the transmission shaft 51 rotates, it drives the sprocket 1 53 to rotate, the sprocket 1 53 drives the chain 54 to rotate, the chain 54 drives the sprocket 2 55 to rotate, the sprocket 2 55 drives the reciprocating screw rod 57 to rotate, the reciprocating screw rod 57 rotates to make the moving block 58 move back and forth along the reciprocating screw rod 57 and the slide groove in the dust removal box 1, and the moving block 58 drives the scraper block 59 to move back and forth to clean the dust on the surface of the dustproof net 56, so as to prevent the dustproof net 56 from being blocked and affecting the filtering effect; Pull the handle on the dustproof net 56 to make it easier to move the dustproof net 56 out of the dust removal box 1.

[0040] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
