[0013] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0014] As attached Figure 1 To be continued Figure 5 As shown, an embodiment of this utility model provides a conveying device for alumina powder, including a conveying device 1, a laying device 2, and a crushing device 3. The laying device 2 is movably installed at the left end of the conveying device 1, and the crushing device 3 is fixedly connected to the middle of the conveying device 1. like Figure 2 As shown, the conveying device 1 includes a conveyor frame 11, a top cover 13, and a cleaning brush 112. A conveyor belt 12 is installed on the top of the conveyor frame 11. The top of the conveyor frame 11 is fixedly connected to the top cover 13. A steam port 14 is opened on the top of the top cover 13. Infrared irradiation lamps 15 are fixedly connected to both ends of the top of the top cover 13. A side cover 16 is fixedly connected to the right end of the top cover 13. A guide hopper 17 is fixedly connected to the bottom of the side cover 16. A lower guide hopper 17 is fixedly connected to the bottom of the guide hopper 17. The drop outlet 18 and the upper sides of the conveyor frame 11 are fixedly connected to guide blocks 19. The conveyor belt 12 is movably installed below the guide blocks 19. The right end of the conveyor frame 11 is fixedly connected to the conveyor motor 110. The output end of the conveyor motor 110 is fixedly connected to the belt drive component 111. One end of the belt drive component 111 is connected to one end of the conveyor belt 12. The cleaning brush 112 is rotatably installed inside the guide hopper 17 on the left end. The cleaning brush 112 is rotatably installed at the bottom of the right end of the conveyor belt 12.

[0015] The belt drive component 111 includes two drive pulleys and a drive belt. One drive pulley is connected to the drive shaft at one end of the conveyor belt 12, and the other pulley is fixedly sleeved on one end of the cleaning brush 112.

[0016] Specifically, the conveyor motor 110 controls the conveyor belt 12 to convey materials. Through the action of the belt drive component 111, the cleaning brush 112 rotates at the bottom right end of the conveyor belt 12. When the alumina powder is conveyed to the inside of the guide hopper 17 by the conveyor belt 12, the cleaning brush 112 cleans the surface of the conveyor belt 12, causing the alumina powder to fall into the inside of the guide hopper 17 and be discharged from the drop outlet 18 by gravity.

[0017] The guide block 19 guides the alumina powder to the middle of the conveyor belt 12, preventing the alumina powder from falling into the gap between the conveyor belt 12 and the conveyor frame 11.

[0018] In addition, by setting an infrared irradiation lamp 15, the infrared irradiation lamp 15 irradiates the alumina powder on the surface of the conveyor belt 12. When the infrared light radiates to the surface of the alumina, it is selectively absorbed by the adsorbed water in the alumina. The absorbed light energy is instantly converted into heat energy, causing the water to change from liquid to gas and be discharged through the steam port 14, thereby drying the alumina and preventing the alumina from absorbing water and causing clumping.

[0019] like Figure 4As shown, the laying device 2 includes a feed pipe 21, a feed hopper 22 is fixedly connected to the top of the feed pipe 21, movable plates 25 are fixedly connected to both sides of the feed pipe 21, a discharge plate 23 is fixedly installed at the bottom of the feed pipe 21, the discharge plate 23 is inclined to the right, a plurality of dispersing strips 24 are fixedly connected to the top of the left side of the discharge plate 23, the plurality of dispersing strips 24 are distributed in a fan shape, and a vibration motor 29 is fixedly connected to the left end of the feed pipe 21.

[0020] The top cover 13 has two fixed plates 26 on both sides of its left end. The top of the fixed plates 26 has two fixed limit rods 27 on both ends. The movable plate 25 is movably installed on the outer surface of the limit rods 27. The outer surface of the limit rods 27 is movably sleeved with a vibration spring 28. The vibration spring 28 is located between the fixed plate 26 and the movable plate 25. The feed pipe 21 is movably sleeved inside the top cover 13.

[0021] Specifically, alumina powder is fed through the feed hopper 22 and falls through the feed pipe 21 to the left end of the discharge plate 23. At this time, the vibration motor 29 works. Through the reaction force of the vibration motor 29 and the vibration spring 28, the feed pipe 21 and the discharge plate 23 vibrate, causing the alumina powder to slide to the right end through the discharge plate 23. Through the action of the dispersing strip 24, the alumina powder is dispersed and spread on the top of the conveyor belt 12, making the alumina powder spread more evenly, which is convenient for the infrared irradiation lamp 15 to dry the alumina powder.

[0022] like Figure 5 As shown, the crushing device 3 includes a fixed frame 31, a rotating motor 32 is fixedly connected to the side of the fixed frame 31, a rotating shaft 33 is fixedly connected to the output end of the rotating motor 32, a movable cam 34 is fixedly sleeved on the outer surface of the rotating shaft 33, and the fixed frame 31 is fixedly installed on the top of the top cover 13.

[0023] The crushing device 3 also includes a support plate 35, which is fixedly installed on the top wall of the top cover 13. Sliding grooves 36 are provided at both ends of the support plate 35. A fixed rod 37 is fixedly connected inside the sliding groove 36. A compression spring 39 is sleeved on the outer surface of the fixed rod 37. An inclined surface is provided on the left side of the bottom of the support plate 35. A compression plate 38 is slidably installed on the left side of the support plate 35. Movable blocks 310 are fixedly connected at both ends of the right side of the compression plate 38. The movable blocks 310 are movably sleeved on the outer surface of the fixed rod 37. The compression spring 39 is located between the movable blocks 310 and the sliding groove 36. A top rod 311 is fixedly connected to the top of the compression plate 38. A ball bearing 312 is rotatably installed on the top of the top rod 311. An inclined surface corresponding to the bottom of the support plate 35 is provided at the bottom of the compression plate 38. The top rod 311 is movably sleeved on the top of the top cover 13. The ball bearing 312 is rotatably installed on the outer surface of the movable cam 34.

[0024] Furthermore, when alumina powder clumps together, it moves to the side of the support plate 35 and is intercepted by the lower end of the support plate 35, causing the alumina powder to accumulate on the left side of the support plate 35. At this time, the rotating motor 32 controls the rotating shaft 33 and the movable cam 34 to rotate. During the rotation of the movable cam 34, it pushes the ball bearing 312 and the top rod 311 to descend, causing the extrusion plate 38 to descend along the support plate 35. The bottom of the extrusion plate 38 presses against the top of the conveyor belt 12, breaking up the clumps of alumina powder, which facilitates the subsequent drying by the infrared irradiation lamp 15.

[0025] The working process of this utility model is as follows: In use, the conveyor motor 110 controls the conveyor belt 12 to convey materials. Through the action of the belt drive component 111, the cleaning brush 112 rotates at the bottom right end of the conveyor belt 12. Alumina powder is fed through the feed hopper 22 and falls through the feed pipe 21 to the left end of the discharge plate 23. At this time, the vibrating motor 29 works. Through the reaction force of the vibrating motor 29 and the vibrating spring 28, the feed pipe 21 and the discharge plate 23 vibrate, causing the alumina powder to slide to the right end through the discharge plate 23. Through the action of the dispersing strip 24, the alumina powder is dispersed and spread on the top of the conveyor belt 12. As the alumina powder is conveyed by the conveyor belt 12, it is irradiated by an infrared lamp 15. When the infrared light radiates onto the surface of the alumina, it is selectively absorbed by the adsorbed water in the alumina. The absorbed light energy is instantly converted into heat energy, causing the water to change from a liquid state to a gaseous state, and then discharged through the steam outlet 14. When the agglomerated alumina moves to the side of the support plate 35, it is intercepted by the lower end of the support plate 35, causing the alumina powder to accumulate on the left side of the support plate 35. At this time, the rotating motor 32 controls the rotating shaft 33 and the movable cam 34 to rotate. During the rotation of the movable cam 34, the ball bearing 312 and the push rod 311 are pushed down, causing the extrusion plate 38 to descend along the support plate 35. The bottom of the extrusion plate 38 presses against the top of the conveyor belt 12 and the inclined surface of the support plate 35, breaking up the agglomerated alumina powder. It is then dried again by the rear infrared irradiation lamp 15 and finally conveyed to the inside of the guide hopper 17 by the conveyor belt 12 and discharged through the drop outlet 18. When the alumina powder is conveyed to the inside of the guide hopper 17 by the conveyor belt 12, the cleaning brush 112 cleans the surface of the conveyor belt 12, causing the alumina powder to fall into the inside of the guide hopper 17 and be discharged from the drop outlet 18 by gravity.
