[0002] In the production process of barite powder, a large amount of dust is generated due to the grinding and crushing of minerals. This dust will not only permeate the entire production environment, causing a serious decline in air quality, but also cause wear and tear on production equipment and increase maintenance costs. What is more serious is that workers who are exposed to these high concentrations of dust for a long time are prone to occupational diseases such as pneumoconiosis, posing a major threat to their health and safety. Therefore, effectively controlling and reducing dust emissions in the production process is of great significance to protecting workers' health, improving production efficiency and maintaining environmental quality.

[0037] Working principle: When in use, air can be injected into the liquid storage chamber 15 through the air intake pipe 13 and the air intake chamber 11, and in conjunction with the air guide pipe 19. The dust in the air can be absorbed through the contact effect between the dust in the air and the moisture inside the liquid storage chamber 15. Then, the filtered air can be discharged to the outside through the exhaust chamber 12 and the exhaust pipe 14, thereby achieving a dust reduction effect.

[0038] The lower end of the air guide tube 19 is tilted, and when the air passes through the air guide tube 19 and is pushed downward to the liquid storage chamber 15, the air guide tube 19, the rotating plate 18, the scraper 232, and the movable disk 22 can be driven to rotate; first, the rotating air guide tube 19 can improve the contact effect between air and moisture; second, the first filter 2 is set to block the bubbles in the moisture, and the bubbles can be cut at the lower end of the first filter 2 by the rotating scraper 232, and the dust in the bubbles can be discharged outward, thereby improving the contact effect between dust and moisture; third, the rotating cleaning brush 241 can be at the upper end of the first filter 2, and the dust at the lower end of the first filter 2 can be brushed downward, so as to achieve the effect of cleaning the first filter 2 and ensure the blocking effect of the first filter 2 on bubbles.

[0041] The first fixed ring 23 and the second fixed ring 231 are provided so that the rotating movable disk 22 can drive the scraper 232 to rotate.

[0042] In another embodiment provided by the present invention, a liquid guide cylinder 32 is fixedly installed in the middle of the dust suppression tank 1, a liquid guide tube 3 is fixedly installed at the lower end of the outer periphery of the dust suppression tank 1, and the two ends of the liquid guide tube 3 are respectively connected to the lower side of the inner cavity of the liquid storage cavity 15 and the lower end of the liquid guide cylinder 32. An infusion pump 31 is fixedly installed at the liquid guide tube 3, a liquid guide hole 33 is opened on the outer periphery of the liquid guide cylinder 32, and a liquid outlet hole 36 is opened at the lower end of the movable frame 24; a through cavity 240 is opened in the middle of the air guide tube 19, and a through cavity 240 is provided on the outer periphery thereof. The outer wall of the air guide tube 19 is fixedly connected to the bracket 242, a turbine 244 is rotatably installed in the through cavity 240, a driven gear 245 is rotatably installed on the periphery of the bracket 242, and a driving gear 243 meshing and connected with the driven gear 245 is fixedly installed on the periphery of the turbine 244; a waist-shaped groove frame 246 is fixedly installed on the upper end of the movable frame 24, and an eccentric pin shaft 247 is fixedly installed on the periphery of the lower end of the driven gear 245, and the eccentric pin shaft 247 is slidably installed in the waist-shaped groove frame 246; the liquid guide The outer periphery of the cylinder 32 is rotatably mounted with a liquid guide ring 34, the liquid guide hole 33 is arranged in the liquid guide ring 34, the outer periphery of the liquid guide ring 34 is fixedly mounted with a liquid guide plug 35, the outer periphery of the air guide tube 19 is fixedly mounted with a limit plug 248, and the movable frame 24 is plugged and installed between the liquid guide plug 35 and the limit plug 248; the inner periphery of the liquid guide cylinder 32 is plugged and installed with a movable plate 4, the upper end of the movable plate 4 is rotatably mounted with a first threaded rod 41 threadedly connected to the liquid guide cylinder 32, and the lower end of the movable plate 4 is fixed by a connecting rod A second threaded rod 42 is installed, and a second filter screen 43 and a dust collecting sleeve 44 are installed on the outer periphery of the second threaded rod 42. A threaded ring 46 threadedly connected to the second threaded rod 42 is provided on the lower side of the dust collecting sleeve 44; a limiting slide rod 48 is fixedly installed between the upper and lower sides of the inner cavity of the dust collecting sleeve 44, and a sealing plate 47 slidably connected to the limiting slide rod 48 is provided in the dust collecting sleeve 44, and a spring 45 mounted on the outer periphery of the limiting slide rod 48 is fixedly installed between the sealing plate 47 and the inner wall of the dust collecting sleeve 44.

[0043] Specifically, a liquid guide tube 3 is provided, and an infusion pump 31 is started, so that the water in the liquid storage cavity 15 can be guided into the liquid guide cylinder 32, and then through the liquid guide hole 33 outside the liquid guide cylinder 32, and in conjunction with the liquid guide ring 34, the liquid guide plug 35, the movable frame 24 and the liquid outlet hole 36, at the upper end of the first filter screen 2, the water is redirected from top to bottom into the liquid storage cavity 15, and in conjunction with the scraper 232, the cleaning effect of the dust on the surface of the first filter screen 2 is improved, wherein the dust in the water can be blocked by the second filter screen 43 inside the liquid guide cylinder 32;

[0044] When water passes through the liquid guide tube 32 from bottom to top, the water flow can drive the sealing plate 47 to move upward, so that the sealing plate 47 and the lower side of the inner cavity of the dust collecting sleeve 44 are separated from each other, so that water and dust can enter the dust collecting sleeve 44. Due to the second filter 43, the dust can be blocked. When the infusion pump 31 is turned off, the water stops moving. At this time, under the action of the spring 45 restoring the deformation, the sealing plate 47 is reset downward to fit with the lower side of the inner cavity of the dust collecting sleeve 44, so that the dust can be suppressed in the dust collecting sleeve 44.

[0045] At the upper end of the liquid guide cylinder 32, the first threaded rod 41 is rotated, and through the threaded connection between the two, the dust collecting sleeve 44 can be installed and removed in the liquid guide cylinder 32, and the height of the dust collecting sleeve 44 can also be adjusted;

[0046] First, when the dust collecting sleeve 44 is aligned with the liquid guiding hole 33, the liquid guiding hole 33 can be sealed. When the infusion pump 31 is turned off, the water inside the liquid storage chamber 15 can be prevented from entering the liquid guiding tube 32 through the liquid guiding hole 33, which can prevent the dust inside the second filter 43 and the dust collecting sleeve 44 from interfering with the water and prevent the water from entering the movable frame 24, thereby preventing the water from spraying downward through the liquid outlet hole 36 and preventing the first filter 2 from affecting the bubble barrier effect.

[0047] Secondly, after the dust collecting sleeve 44 is taken out from the liquid guide cylinder 32, the dust collecting sleeve 44 and the second filter screen 43 can be disassembled again by disassembling the threaded ring 46 on the outer periphery of the second threaded rod 42, so as to facilitate the recovery of dust inside the dust collecting sleeve 44;

[0048] When the air duct 19 rotates, driving the movable frame 24 to rotate, and cooperating with the cleaning brush 241 to clean the dust on the lower surface of the first filter screen 2, the air moving downward inside the air duct 19 can drive the turbine 244 to rotate, and then through the meshing connection between the driving gear 243 and the driven gear 245 and the sliding connection between the eccentric pin shaft 247 and the waist-shaped groove frame 246, the movable frame 24 can be driven to reciprocate between the liquid guide block 35 and the limit block 248, thereby improving the cleaning effect of the cleaning brush 241 on the dust on the surface of the first filter screen 2.
