Description

Technical Field

[0001] This utility model relates to the field of chemical powder production technology, and in particular to a chemical powder product screening device. Background Technology

[0002] Chemical powders refer to powdery substances used in the chemical industry. These substances can be raw materials, intermediates, or final products.

[0003] In existing technologies, chemical powders are typically screened by directly pouring the powder into the screening device. However, due to various external factors, the powder may agglomerate, preventing it from passing through the screen smoothly. This results in a large amount of powder remaining on the screen, significantly reducing the effective screening area and drastically decreasing screening efficiency. Furthermore, specialized crushing or other processing equipment is often required to pre-treat the agglomerated powder before re-screening. This additional step not only increases equipment and labor costs but also prolongs the entire production process, leading to a significant increase in processing costs. Therefore, a chemical powder screening device is needed to solve these problems. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-6This utility model provides an embodiment of a chemical powder product screening device, including a base plate 1; it also includes a support plate 21 and a discharge assembly. A support leg 4 is fixedly connected to the bottom of the base plate 1, and the support plate 21 is fixedly connected to the top of the base plate 1. A conveying pipe 22 is fixedly connected to the top of the support plate 21, and a crushing box 23 is fixedly connected to the top of the conveying pipe 22. A funnel 24 is fixedly connected to the top of the crushing box 23. A screening barrel 25 is fixedly connected to the outside of the conveying pipe 22, and a screen barrel 26 is fixedly connected to the inside of the screening barrel 25. A motor 27 is fixedly connected to the outside of the conveying pipe 22. A crushing roller 28 is fixedly connected to the output end of the screen. A motor 27 drives the crushing roller 28 to rotate. A gear 29 is fixedly connected to the outside of the crushing roller 28. A gear 210 meshes with the outside of the gear 29. A crushing roller 211 is fixedly connected to the outside of the gear 210. A rotating disk 212 is fixedly connected to the outside of the crushing roller 211, away from the gear 210. A rotating belt 213 is driven to the outside of the rotating disk 212. A rotating disk 214 is driven to the outside of the rotating belt 213, away from the rotating disk 212. A dispersing component is provided on the outside of the rotating disk 214. The external part of the screening bin 25 is equipped with a discharge component; the dispersing component includes a spiral blade 215, which is fixedly connected to the outside of the rotating disk 214. A rotating rod 216 is fixedly connected to the outside of the spiral blade 215, a ring plate 217 is fixedly connected to the outside of the rotating rod 216, a scraper 218 is fixedly connected to the outside of the ring plate 217, and a rotating disk 219 is fixedly connected to the outside of the scraper 218. A discharge box 220 is fixedly connected to the bottom of the screening bin 25. The powder to be screened is fed into the crushing box 23 through the funnel 24. At this time, the motor 27 drives the crushing roller 28 to move outward. The rotation of gear 29 causes gear 29 to drive the external crushing roller 211 of gear 210 to rotate simultaneously with crushing roller 28, thereby crushing the agglomerates in the powder. Then, the rotating belt 213 outside crushing roller 211 drives rotating disk 214 to rotate, which in turn drives spiral blade 215 to rotate, thus bringing the crushed powder into the screen barrel 26. The screen barrel 25 drives the rotating rod 216 to rotate the ring 217 outside to rotate, which in turn drives scraper 218 to rotate inside the screen barrel 26, thereby driving the powder camera to screen the powder.

[0022] Please see Figure 2-5In this embodiment, a through hole is provided on the conveying pipe 22, and the spiral blade 215 is rotatably connected to the inside of the conveying pipe 22 through the through hole. The presence of the conveying pipe 22 facilitates the installation of other components. The scraper 218 is in contact with the inner wall of the screen barrel 26. The presence of the scraper 218 facilitates the movement of powder inside the screen barrel 26 for sieving. When the rotating disk 212 rotates, the rotating belt 213 drives the rotating disk 214 to rotate simultaneously. The presence of the rotating belt 213 facilitates the simultaneous rotation of the rotating disk 214 and the rotating belt 213.

[0023] Please see Figure 6 In this embodiment, the discharge assembly includes a coarse material box 31, which is fixedly connected to the outside of the screening barrel 25. A connecting belt 32 is driven to the outside of the rotating disk 3 219. A rotating disk 4 33 is driven to the end of the connecting belt 32 away from the rotating disk 3 219. A cam 34 is fixedly connected to the outside of the rotating disk 4 33. A rotating plate 35 is rotatably connected inside the coarse material box 31. Due to the connection belt 32, it is beneficial to provide power for the rotation of the rotating disk 4 33 through the rotation of the rotating disk 3 219. When the cam 34 is close to the rotating plate 35, the rotating plate 35 rotates upward. When the cam 34 is away from the rotating plate 35, the rotating plate 35 moves downward. Due to the cam 34, it is beneficial to drive the rotating plate 35 to vibrate.

[0024] During operation, the powder to be sieved is fed into the crushing chamber 23 through the funnel 24. At this time, the motor 27 drives the gear 29 outside the crushing roller 28 to rotate, which in turn drives the crushing roller 211 outside the gear 210 to rotate simultaneously with the crushing roller 28, thereby crushing the lumps in the powder. Subsequently, the rotating belt 213 outside the crushing roller 211 drives the rotating disk 214 to rotate, which in turn drives the spiral blades 215 to rotate, thus carrying the crushed powder into the screen barrel 26. The screen barrel 25 drives the rotating rod 216 to rotate the ring 217 outside the rotating rod 216, which in turn drives the scraper 218 to rotate inside the screen barrel 26, thereby driving the powder camera to screen the powder. The coarser powder falls into the coarse material box 31 through the continuous rotation of the scraper 218. The rotating rod 216 drives the connecting belt 32 outside the rotating disk 319 to rotate outside the rotating disk 43, which in turn drives the cam 34 to move away from or towards the rotating plate 35, thereby causing the rotating plate 35 to vibrate continuously and discharge the coarse material.

[0025] Through the above steps, the powder to be screened is fed into the crushing box 23 through the funnel 24. The motor 27 drives the gear 29 outside the crushing roller 28 to rotate. The gear 29 drives the gear 210 and the crushing roller 211 to rotate synchronously. The powder agglomerates are crushed by the double roller extrusion, which effectively avoids agglomeration from interfering with subsequent production.
