[0015] (III) Beneficial effects The present invention provides a dust recycling device for gypsum production. It has the following beneficial effects: (1). The dust recycling equipment for gypsum production is provided with a spraying device. During the spraying process by starting the rotary nozzle, the linear motor is started to work. The linear motor can drive the sliding rod to move up and down. The sliding rod can drive the rotary nozzle to swing reciprocally through the ejector rod. At the same time, the bottom of the sliding rod can drive the sewage discharge cover plate to move. When the sliding rod moves downward, it can spray the rotary nozzle downward and open the sewage discharge port through the pull rod, so that the spraying of the rotary nozzle can spray the calcium carbonate at the bottom into the collection box for collection, preventing secondary pollution caused by residues remaining at the bottom of the dust suction pipe.

[0016] (2). The dust recycling equipment for gypsum production is provided with a collection device. When the sliding rod moves downward, the sliding rod can drive the pressing plate to move downward to compact the calcium carbonate. When the sliding rod moves upward to drive the pressing plate to move upward, the rotating plate rotates counterclockwise back to the initial position due to the elastic force, and the rotating plate can drive the telescopic plate to move to the right to push and concentrate the calcium carbonate for placement.

[0017] (3). The dust recycling equipment for gypsum production is provided with a splash-proof device. When the rotary nozzle rotates and sprays, the small-sized calcium carbonate is easily splashed by the spraying. The splash-proof triangular plate can effectively prevent the splash of calcium carbonate. At the same time, the inclined surface of the splash-proof triangular plate can reduce the impact on the amount of dust inhaled into the dust suction pipe.

[0018] (4). The dust recycling equipment for gypsum production is provided with a knocking device. When the pressing plate moves downward, the action and reaction forces between the arc-shaped rod and the rotating plate cause the arc-shaped rod to move upward to push the sliding plate to slide. The sliding plate can push the knocking rod downward through the fixed rod and the spring rod, so that the knocking rod can knock and vibrate the semi-circular pressing block to remove the residues attached to the outer wall of the semi-circular pressing block and improve the subsequent compaction quality.

[0019] (5). The dust recycling equipment for gypsum production is provided with an impact ball and an S-shaped arc rod. When the sewage discharge cover plate returns to the initial position due to the push of the pull rod, the sewage discharge cover plate can push the connecting column to move leftward. The connecting column can drive the arc-shaped impact rod to slide upward, so that the impact ball collides with the impact convex block to generate impact vibration, making the splash-proof triangular block produce a self-vibrating dust removal effect. At the same time, the connecting column drives the S-shaped arc rod to frictionally vibrate the L-shaped filter plate to improve the filtering effect of the L-shaped filter plate.

One end of a pull rod 26 is rotatably installed on the lower outer wall of the slide rod 22. The other end of the pull rod 26 is rotatably installed on the outer wall of a sewage cover plate 27. A sewage discharge port 25 is fixedly opened at the bottom of the dust suction pipe 1. The sewage cover plate 27 is slidably installed at the bottom of the sewage discharge port 25. The outer wall of the linear motor 21 is fixedly installed on the top outer wall of the dust suction pipe 1. The rotary spray head 24 is rotatably installed at the bottom output end of a liquid storage tank 3. The liquid storage tank 3 is fixedly installed on the top outer wall of the dust suction pipe 1. The sewage discharge port 25 is arranged at the inlet of the dust suction pipe 1. The slide rod 22 penetrates and is slidably installed at the bottom of the dust suction pipe 1. The upper right outer wall of the sewage cover plate 27 is slidably installed on the bottom outer wall of the dust suction pipe 1. By arranging the spraying device, when the slide rod 22 moves downward, the rotary spray head 24 can be sprayed downward and the sewage discharge port 25 can be opened through the pull rod 26, so that the spraying of the rotary spray head 24 can spray the calcium carbonate at the bottom into the inside of a collection box 41 for collection, preventing secondary pollution caused by residues remaining at the bottom of the dust suction pipe 1.

[0024] Such as Figure 2 , Figure 3 , Figure 4 And Figure 5As shown in the figure, in the present invention, a collection device is provided at the bottom of the dust suction pipe 1. The collection device includes a collection box 41, which is fixedly installed on the outer wall of the bottom of the dust suction pipe 1. An L-shaped filter plate 42 is fixedly installed on the inner wall of the collection box 41. There is no filter opening on the vertical surface at the right end of the L-shaped filter plate 42. A pressing plate 43 is fixedly installed on the outer wall of the bottom of the sliding rod 22. A rotating plate 44 is rotatably installed at the right end of the L-shaped filter plate 42. The bottom outer wall of the rotating plate 44 is rotatably installed on the top of the telescopic plate 45. The bottom of the telescopic plate 45 is slidably installed on the inner wall of the bottom of the collection box 41. The bottom outer wall of the rotating plate 44 is elastically connected to the outer wall of the right end of the L-shaped filter plate 42 through an elastic sheet. A knocking device is arranged inside the pressing plate 43. The knocking device includes an arc-shaped rod 51, which penetrates and slides on the pressing plate 43. The top of the arc-shaped rod 51 is rotatably installed on the outer wall of the sliding plate 52. The sliding plate 52 is slidably installed on the inner wall of the pressing plate 43. One end of a fixed rod 53 is fixedly installed on the outer wall of the sliding plate 52. The other end of the fixed rod 53 is rotatably installed on the top of the spring rod 54. The spring rod 54 penetrates and slides on the bottom of the pressing plate 43. A knocking rod 55 is rotatably installed at the bottom of the spring rod 54. A semi-circular pressing block 56 is fixedly installed on the outer wall of the bottom of the pressing plate 43. The knocking rod 55 is arranged outside near the outside of the semi-circular pressing block 56. By providing the collection device, when the sliding rod 22 moves downward, the sliding rod 22 can drive the pressing plate 43 to move downward to compact the calcium carbonate. When the sliding rod 22 moves upward to drive the pressing plate 43 to move upward, the rotating plate 44 rotates counterclockwise back to the initial position due to the elastic force, and the rotating plate 44 can drive the telescopic plate 45 to move to the right to push and concentrate the calcium carbonate for placement.

[0025] As Figure 3 and Figure 6 shown in the figure, in the present invention, a splash-proof device is provided inside the dust suction pipe 1. The splash-proof device includes a splash-proof triangular plate 61, which is fixedly installed at the entrance of the dust suction pipe 1. The inclined surface of the splash-proof triangular plate 61 faces outward. An arc-shaped impact rod 62 penetrates and slides at the bottom of the splash-proof triangular plate 61. An impact ball 63 is fixedly installed at the top of the arc-shaped impact rod 62. An impact convex block 64 is fixedly installed on the inner wall of the splash-proof triangular plate 61. The impact ball 63 is arranged outside near the outside of the impact convex block 64. A connecting column 65 is rotatably installed at the bottom of the arc-shaped impact rod 62. The bottom of the connecting column 65 is rotatably installed on the top of the S-shaped arc rod 66. A vibration ball 67 is fixedly installed on the outer wall of the bottom of the S-shaped arc rod 66. The vibration ball 67 is arranged near the top filter hole of the L-shaped filter plate 42. By providing the splash-proof device, when the rotary nozzle 24 rotates for spraying, the small-sized calcium carbonate is easily splashed by the spray. The splash-proof triangular plate 61 can effectively prevent the splash of the calcium carbonate, and at the same time, the inclined surface of the splash-proof triangular plate 61 can reduce the influence on the amount of inhaled dust in the dust suction pipe 1.

[0026] During operation (or use), when the rotary sprinkler 24 is started for spraying and washing, the linear motor 21 is started to work. The linear motor 21 can drive the slide rod 22 to move up and down. The slide rod 22 can drive the ejector rod 23 to rotate reciprocally. The reciprocating rotation of the ejector rod 23 drives the rotary sprinkler 24 to swing reciprocally. At the same time, the bottom of the slide rod 22 can drive the sewage discharge cover plate 27 to move reciprocally to open and close the sewage discharge port 25. When the slide rod 22 moves downward, the rotary sprinkler 24 can be sprayed downward and the sewage discharge port 25 can be opened through the pull rod 26, so that the spraying of the rotary sprinkler 24 can spray the calcium carbonate at the bottom into the collection box 41 for collection, preventing secondary pollution caused by residue at the bottom of the dust suction pipe 1. By setting up a collection device, the sprayed calcium carbonate can slide and filter on the L-shaped filter plate 42 to filter and recycle the sprayed solution for convenient reuse later. The filtered calcium carbonate will slide to the lower right end of the collection box 41 for collection. When the slide rod 22 moves downward, the slide rod 22 can drive the pressing plate 43 to move downward to compact the calcium carbonate. When the slide rod 22 moves upward to drive the pressing plate 43 to move upward, the rotating plate 44 rotates counterclockwise back to the initial position due to the elastic force. The rotating plate 44 can drive the telescopic plate 45 to move to the right to push and concentrate the calcium carbonate. By setting up a knocking device, when the pressing plate 43 moves downward, the action and reaction forces between the arc rod 51 and the rotating plate 44 cause the arc rod 51 to move upward by the reaction force of the rotating plate 44, thereby driving the slide plate 52 to slide. The slide plate 52 can push the knocking rod 55 downward through the fixed rod 53 and the spring rod 54, so that the knocking rod 55 can knock and vibrate the semi-circular pressing block 56 to remove the residue attached to the outer wall of the semi-circular pressing block 56 and improve the subsequent compaction quality. By setting up a splash-proof device, when the rotary sprinkler 24 rotates and sprays, the small-sized calcium carbonate is easily splashed by the spray. The splash-proof triangular plate 61 can effectively prevent the splash of calcium carbonate. At the same time, the inclined surface of the splash-proof triangular plate 61 can reduce the impact on the amount of inhaled dust in the dust suction pipe 1, enabling the dust to smoothly enter the dust suction pipe 1 through the inclined surface. By setting up the impact ball 63 and the S-shaped arc rod 66, when the sewage discharge cover plate 27 returns to the initial position due to the push of the pull rod 26, the sewage discharge cover plate 27 can push the connecting column 65 to move leftward. The connecting column 65 can drive the arc-shaped impact rod 62 to slide upward, causing the impact ball 63 to collide and vibrate with the impact bump 64, resulting in the self-vibration and dust removal effect of the splash-proof triangular plate 61. At the same time, the connecting column 65 drives the S-shaped arc rod 66 to frictionally vibrate the L-shaped filter plate 42 to improve the filtering effect of the L-shaped filter plate 42. In summary, by setting up a spraying and washing device, when the slide rod 22 moves downward, the rotary sprinkler 24 can be sprayed downward and the sewage discharge port 25 can be opened through the pull rod 26, so that the spraying of the rotary sprinkler 24 can spray the calcium carbonate at the bottom into the collection box 41 for collection, preventing secondary pollution caused by residue at the bottom of the dust suction pipe 1.
