[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figures 1 to 7 , Figure 9 As shown, the present invention provides a dust removal device for mixing compounding agents, including a filter dust removal box 1, wherein an air inlet pipe 11 and an air outlet groove 12 are respectively provided on opposite side walls of the filter dust removal box 1; the filter dust removal box 1 is connected to a spray dust removal box 2 through the air outlet groove 12; a top plate filter assembly 3 is disposed in the filter dust removal box 1, and the air inlet pipe 11 is connected to the top plate filter assembly 3; a rotary drum filter assembly 4 is disposed in the spray dust removal box 2; the top plate filter assembly 3 includes a water tank 31 disposed in the filter dust removal box 1, and an air inlet pipe 11 penetrates into the water tank 31, and a filter plate 32 is movably installed on the top surface of the water tank 31; the rotary filter assembly 4 includes a spray plate 41 and an outer cylinder 42 arranged sequentially from top to bottom in the spray dust removal box 2, a rotary cylinder 43 is rotatably installed inside the outer cylinder 42, and a semi-circular groove group 44 is arranged circumferentially on the outer peripheral wall of the outer cylinder 42, the position of the spray plate 41 corresponds vertically to the position of the semi-circular groove group 44, and an exhaust groove 45 corresponding to the position of the semi-circular groove group 44 is provided on the outer wall at the bottom of the spray dust removal box 2.

[0039] The dust-laden air generated during the mixing of the compounding agents enters the filter dust collection box 1 through the air inlet pipe 11 (a fan can be installed on the air inlet pipe 11 to increase the pressure of the dust-laden air entering the filter dust collection box 1). When the dust-laden air enters the water tank 31 inside the filter dust collection box 1 through the air inlet pipe 11, the particles in the dust-laden air can be captured by water, thereby reducing the dust particle content in the air. After the dust-laden air floats out of the water tank 31, it can be filtered again through the filter plate 32. The filtered dust-laden air can then enter the spray dust collection box 2 through the air outlet 12 from the filter dust collection box 1, where it is sprayed under the action of the spray plate 41, thereby reducing the suspended particulate matter content in the dust-laden air. This causes the air to sink under the influence of gravity, thereby improving the quality of the exhaust air. The dust-laden air, after being sprayed, enters the rotating drum 43 along with the sprayed water through the semi-circular groove group 44 on the outer peripheral wall of the outer cylinder 42 (the sprayed water can accumulate in the rotating drum 43, and a drain pipe can be connected to the rotating drum 43, with the end of the drain pipe away from the rotating drum 43 extending to the outside of the filter dust collection box 1, so as to facilitate the discharge treatment of the sprayed water in the rotating drum 43). A motor can be installed on the outer cylinder 42 to drive the rotating drum 43 to rotate, thereby adjusting the position of the rotating drum 43 so that the dust-laden air after spraying can be discharged through the arc-shaped through groove group 45 and the exhaust groove 45 on the outer peripheral wall of the outer cylinder 42.

[0040] Example 2

[0041] Based on Example 1, such as Figures 2 to 4 As shown, multiple air holes 311 are arranged in an array on the top surface of the water tank 31. A return spring 312 is fixedly installed at the bottom of each air hole 311. The filter plate 32 is movably installed on the top surface of the water tank 31 and is parallel to the top surface of the water tank 31. Multiple stoppers 313 corresponding to the air holes 311 are provided on the bottom surface of the filter plate 32. The stoppers 313 are connected to the return springs 312. The size and shape of the filter plate 32 are adapted to the size and shape of the opening on the top surface of the water tank 31. The stoppers 313 have an inverted frustum structure, and the small diameter end of the stopper 313 is movably inserted into the air hole 311. The diameter of the large diameter end of the stopper 313 is larger than the inner diameter of the air hole 311.

[0042] After the dust-laden air enters the water tank 31 in the filter dust removal box 1 through the air inlet pipe 11, it can be discharged from each air hole 311. At the same time as the dust-laden air is discharged, the plug rod 313 can be pushed out from the air hole 311 (that is, the small diameter end of the plug rod 313 is pushed towards the top of the air hole 311). At this time, the air can be blown out through the gap between the small diameter end of the plug rod 313 and the air hole 311. After passing through the water in the water tank 31 and the filter plate 32 in sequence, it flows to the top of the water tank 31 and finally enters the spray dust removal box 2 through the air outlet 12 for spray treatment.

[0043] When the dust-laden air pushes the plug rod 313 out of the air hole 311, the filter plate 32 can move up and down in the top opening of the water tank 31 at the same time (the distance the filter plate 32 moves can be determined according to the pressure of the dust-laden air. When the pressure of the dust-laden air is low, that is, when the plug rod 313 cannot be pushed, the plug rod 313 can block the air hole 311, and at this time, no dust removal treatment is performed on the dust-laden air).

[0044] Example 3

[0045] Based on Example 1, such as Figures 1 to 2 , Figure 9 As shown, on the side wall of the air outlet 12 near the spray dust collector 2, a ventilation duct 18 and a push cylinder 13 are arranged sequentially from top to bottom. An extension rod 14 is coaxially arranged on the piston rod of the push cylinder 13. Filter plates 15 and 16 of the same size and shape are arranged at intervals along the length of the extension rod 14. On the side wall of the air outlet 12 away from the spray dust collector 2, a plate groove 17 is arranged that communicates with the filter dust collector 1. The size and shape of the plate groove 17 are adapted to the size and shape of the filter plate 15. The filter plate 15 or the filter plate 16 is movably arranged in the plate groove 17. The filter dust collector 1 and the spray dust collector 2 are connected through the ventilation duct 18.

[0046] When the dust-laden air passes through the water tank 31 and the filter plate 32, it enters the plate groove 17. The filter plate 15 is located in the plate groove 17 near the end of the filter dust removal box 1. Therefore, the dust-laden air can pass through the filter plate 15 and then enter the spray dust removal box 2 through the air outlet groove 12.

[0047] After the filter plate 15 has been used for a period of time, the cylinder 13 can be activated to simultaneously move the filter plate 15 and the filter plate 16, so that the filter plate 16 is located in the plate groove 17 (at this time, the filter plate 15 is located at the upper position in the water tank 31). This allows the air in the water tank 31 to be filtered by the filter plate 16 before entering the spray dust removal box 2, which can prevent the filter plate 15 from becoming clogged after long-term use and reducing the filtration effect.

[0048] Example 4

[0049] Based on Example 1, such as Figures 1 to 2 , Figures 5 to 9As shown, the spray dust collector 2 has an upper longitudinal plate 21 and a lower longitudinal plate 22 vertically arranged from top to bottom. The upper end of the upper longitudinal plate 21 is connected to the top of the spray dust collector 2, and the lower end of the upper longitudinal plate 21 is set on the outer peripheral wall of the outer cylinder 42. The upper end of the lower longitudinal plate 22 is set on the outer peripheral wall of the outer cylinder 42, and the lower end of the lower longitudinal plate 22 is connected to the bottom of the spray dust collector 2. The outer peripheral wall of the outer cylinder 42 is in contact with two opposing inner walls of the spray dust collector 2. The upper longitudinal plate 21 and the lower longitudinal plate 22 can divide the space inside the spray dust collector 2. The rotating drum 43 includes a rotating shaft 431, which is coaxially rotatable inside the outer cylinder 42. Multiple filter discs 432 are provided, and the multiple filter discs 432 are arranged side by side on the rotating shaft 431. The filter discs 432 have a hollow screen structure. Multiple arc-shaped openings 433 are provided, and the arc-shaped openings 433 are arranged along the rotating shaft 431. The axis lengths of the filter discs 432 are arranged side by side on the outer peripheral wall of the filter discs 432, and the position of the arc-shaped opening 433 matches the position of the semi-circular groove group 44. A fan-shaped insert plate group 5 is movably arranged inside the spray dust collection box 2. The positions of the fan-shaped insert plate group 5 and the semi-circular groove group 44 are vertically corresponding. The spray plate 41 and the fan-shaped insert plate group 5 are respectively arranged on both sides of the upper longitudinal plate 21. The semi-circular groove group 44 includes a plurality of semi-circular annular through grooves 441 arranged side by side. The semi-circular annular through grooves 441 are arranged side by side along the axis of the outer cylinder 42. The arc-shaped opening of the semi-circular annular through groove 441 faces the bottom surface of the dust collection box 2. The upper longitudinal plate 21 is vertically arranged at the top of the arc-shaped opening of the semi-circular annular through groove 441. The fan-shaped insert plate group 5 includes a plurality of fan-shaped plates 51 arranged side by side. The number of fan-shaped plates 51 is the same as the number of arc-shaped openings 433, and the position of the fan-shaped plates 51 corresponds one-to-one with the position of the arc-shaped openings 433.

[0050] The upper longitudinal plate 21 and the lower longitudinal plate 22 divide the spray dust collector 2 into two chambers, left and right. Since the outer peripheral wall of the outer cylinder 42 is in contact with the two opposing inner walls of the spray dust collector 2, the spray dust collector 2 is divided into four chambers arranged in an array under the combined action of the upper longitudinal plate 21, the lower longitudinal plate 22 and the outer cylinder 42 (i.e., there is one chamber on each side of the upper longitudinal plate 21 and one chamber on each side of the lower longitudinal plate 22).

[0051] The spray plate 41 is located in the cavity on the left side of the upper longitudinal plate 21 (multiple nozzles are provided on the bottom surface of the spray plate 41, and the spray plate 41 is connected to a water tank with a water pump through a hose, so that the water tank with the water pump can provide spray water for spraying the dusty air. This is existing technology, so it will not be described in detail here). The two ends of the semi-circular annular groove 441 are located in the cavities on the left and right sides of the upper longitudinal plate 21, respectively.

[0052] Dust-laden air is filtered from water tank 31 and enters spray dust collection box 2 through air outlet 12. It can be sprayed under the action of spray plate 41. The sprayed air and spray water enter the filter plate 432 for filtration through semi-circular annular groove 441 (the part corresponding to the position of spray plate 41) and arc-shaped opening 433. The filtered air passes through filter plate 432 and semi-circular annular groove 441 and is discharged from exhaust groove 45. The filtered spray water can be stored at the bottom of spray dust collection box 2.

[0053] An electromagnet is installed on the outer peripheral wall of the rotating shaft 431. An arc-shaped groove 511, matching the outer diameter of the rotating shaft 431, is provided at the center of the sector plate 51. A layer of ferromagnetic material is provided inside the arc-shaped groove 511. The sector plate 51 has a filter mesh structure. A motor for driving the rotating drum 43 can be installed on the outer cylinder 42. It can also drive the filter disc 432 to rotate according to the filtration needs. When the arc-shaped opening 433 on the filter disc 432 rotates to the position of the spray plate 41, the rotation can be adjusted. After being staggered, each sector plate 51 can now be inserted into its corresponding arc-shaped opening 433 (the sector plate 51 is located in the cavity on the right side of the upper longitudinal plate 21, and is positioned above the arc-shaped opening 433 in the filter disc 432). Simultaneously, the arc-shaped groove 511 at the center of the sector plate 51 adheres to the outer peripheral wall of the rotating shaft 431 under magnetic force, which helps to maintain the stable position of the sector plate 51 within the arc-shaped opening 433, thereby allowing the rotating shaft 431 to... The filter disc 432 rotates, causing the arc-shaped opening 433 on the filter disc 432 to rotate to a position corresponding to the spray plate 41. At this time, the spray water from the spray plate 41 can enter the fan-shaped plate 51 inside the arc-shaped opening 433 for filtration (the mesh size of the fan-shaped plate 51 is larger than that of the filter disc 432). The filtered spray water can pass through the filter disc 432 and the semi-circular annular groove 441 on the outer cylinder 42 and be discharged to the bottom of the spray dust collector 2 for collection. The filtered air can be discharged from the exhaust. Discharge from trough 45; after the sector plate 51 has been used for a period of time, it can be rotated so that the rotating shaft 431 drives the filter plate 432 to rotate. When the arc opening 433 on the filter plate 432 rotates to be offset from the position of the spray plate 41, the sector plate 51 in the arc opening 433 can be taken out for cleaning or replacement (a movable door can be provided on the side wall of the spray dust collector 2 away from the spray plate 41, and the movable door is located above the exhaust trough 45, which facilitates the installation or removal of the sector plate 51).
