Detailed implementation manners

[0027] The following will Figures 1-5 make a further detailed description of the present application.

[0028] An embodiment of the present application discloses a dust removal device.

[0029] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a dust removal device includes a dust removal box 1, a dust suction assembly 2, a water spraying assembly 3, a water return assembly 4, a base 5 and a bracket 6. Among them, universal wheels 51 are fixedly installed at the bottom end of the base 5 to facilitate the staff to move the base 5; the bracket 6 is vertically and fixedly installed at the top end of the base 5; the dust removal box 1 is fixedly installed at the top end of the bracket 6. The dust removal box 1 includes a box body 11 and a box cover 12. The inside of the box body 11 is a cavity structure. The right end of the box body 11 is open. The box cover 12 is installed at the open end of the box body 11 through a bolt 8. A dust removal pipe 121 is horizontally installed on the box cover 12, and the dust removal pipe 121 is used to connect the inside and outside of the dust removal box 1; the dust suction assembly 2 is installed inside the box body 11, and the dust suction assembly 2 is used to suck the dust in the target environment into the box body 11; the water spraying assembly 3 is installed on the box body 11, and the water spraying assembly 3 is used to spray the dust sucked into the box body 11 and spray the dust near the dust removal pipe 121; the water return assembly 4 is installed at the top end of the base 5, and the water return assembly 4 is used to return the water in the dust removal box 1 to the water spraying assembly 3.

[0030] The dust suction assembly 2 includes a dust suction placement box 21, a drive motor 22, a rotating shaft 23, and fan blades 24. Among them, the top, front, and back ends of the placement box 21 are all inclined surfaces facing the direction of the dust removal pipe 121, and the bottom end of the placement box 21 is fixedly connected to the inner wall of the dust removal box 1 through a connecting rod 211; the drive motor 22 is fixedly installed in the placement box 21, the rotating shaft 23 is horizontally placed, one end of the rotating shaft 23 passes through the outer wall of the placement box 21 and is fixedly connected to the drive motor 22, and the other end faces the dust removal pipe 121; the fan blades 24 are fixedly installed at one end of the rotating shaft 23 away from the drive motor 22, there are multiple fan blades 24, and the multiple fan blades 24 are equidistantly distributed along the circumferential direction of the rotating shaft 23. When the drive motor 22 works, it drives the rotating shaft 23 to rotate, and then drives the fan blades 24 to rotate at high speed in the reverse direction, so that the fan blades 24 blow air towards the inside of the box body 11, thereby forming a negative pressure inside the box body 11. Due to the pressure difference between the inside and outside of the box body 11, the dust around the dust removal pipe 121 will enter the inside of the box body 11 through the dust removal pipe 121.

[0031] In order to prevent large particulate matter from entering the inside of the box body 11 from the dust removal pipe 121, a disc 7 is threadedly installed on the dust removal pipe 121. Multiple air inlet holes 72 and multiple connection holes 71 are provided on the disc 7, and the multiple air inlet holes 72 and the multiple connection holes 71 are spaced apart along the circumferential direction of the disc 7. When the drive motor 22 works, the dust will enter the inside of the box body 11 through the air inlet holes 72.

[0032] The water spraying assembly 3 includes a water storage tank 31, a first booster pump 32, a first main pipe 33, a second main pipe 34, a first branch pipe group 35 fixedly installed on the first main pipe 33, a second branch pipe group 36 fixedly installed on the second main pipe 34, a plurality of first nozzles 37 fixedly installed on the first branch pipe group 35, and a plurality of second nozzles 38 fixedly installed on the second branch pipe group 36. Among them, both the water storage tank 31 and the first booster pump 32 are fixedly installed at the top end of the dust removal box 1. The water storage tank 31 is fixedly connected to the water inlet end of the first booster pump 32 through a water supply pipe 311. The first booster pump 32 is fixedly connected to the first main pipe 33 and the second main pipe 34 respectively through a tee pipe 321. The first main pipe 33 is vertically placed inside the box body 11. The first branch pipe group 35 is fixedly installed on the first main pipe 33. A plurality of first nozzles 37 are equidistantly distributed along the length direction of the first branch pipe group 35. The first nozzles 37 are fixedly installed on the first branch pipe group 35, and the first nozzles 37 are inserted into the connection holes 71, and the first nozzles 37 spray in the direction towards the outside of the box body 11. The second main pipe 34 is horizontally placed at the top end inside the box body 11. The second branch pipe group 36 is fixedly installed on the second main pipe 34. A plurality of second nozzles 38 are equidistantly distributed along the length direction of the second branch pipe group 36. The second nozzles 38 are fixedly installed on the second branch pipe group 36, and the second nozzles 38 spray in the direction towards the inside of the box body 11. When the dust suction assembly 2 works, the dust around the box body 11 will move towards the direction of the dust removal pipe 121. Then, the first nozzles 37 spray the dust near the dust removal pipe 121 to wet and settle the dust. However, some dust will also enter the inside of the box body 11 through the air inlet holes 72, and the second nozzles 38 wet and settle the dust inside the box body 11. Since the top end, the front end, and the rear end of the placement box 21 are all inclined, the wetted and settled dust will flow down along the inclined surface to the inner bottom end of the dust removal box 1.

[0033] In order to recycle the water sprayed by the second nozzles 38 inside the box body 11, thereby saving water. The water return assembly 4 includes a second booster pump 42, a water return pipe 43, and a sedimentation tank 41. The sedimentation tank 41 is fixedly installed at the top end of the base 5. The sedimentation tank 41 is communicated with the dust removal box 1 through a connecting pipe 411. The inlet end of the second booster pump 42 is fixedly communicated with the sedimentation tank 41. The outlet end of the second booster pump 42 is fixedly communicated with the water return pipe 43. One end of the water return pipe 43 away from the second booster pump 42 is fixedly communicated with the water storage tank 31. A filter screen 431 is fixedly installed inside the water return pipe 43. The water inside the box body 11 enters the sedimentation tank 41 through the connecting pipe 411. After sedimentation in the sedimentation tank 41, it flows back to the water storage tank 31 through the second booster pump 42 and the water return pipe 43. The filter screen 431 can prevent dust and sundries from flowing back to the water storage tank 31.

[0034] The above are all preferred embodiments of this application, and do not limit the protection scope of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
