Description
Technical Field
[0001] This utility model relates to the field of waste circuit board processing technology, and in particular to a waste circuit board sorting and dust removal device. Background Technology
[0002] The sorting of waste circuit boards is of great significance in resource recycling and environmental protection, and is a key link in the process. This process usually includes pretreatment, crushing, sorting and further processing. Each step complements and works closely together to improve the metal recovery rate and resource utilization efficiency. Among these processes, the crushing process in the sorting of waste circuit boards is a key preliminary step for resource recycling and plays a decisive role in the subsequent sorting effect. The core goal of the crushing process is to transform large-sized circuit board materials into suitable particle sizes, promote the initial separation of different components in the circuit board, and thus lay a solid foundation for subsequent efficient sorting.
[0003] When using equipment to crush waste circuit boards, the dust accumulated on the circuit boards will fly around during the crushing process. However, common crushing equipment has obvious shortcomings in dust handling and is difficult to effectively deal with the dust generated when crushing circuit boards. If workers are exposed to such a dusty environment for a long time, their health will be greatly harmed. Moreover, common dust handling methods simply discharge the dust to other places without doing any substantial and effective treatment of the dust. In view of this, this application proposes a waste circuit board sorting and dust removal device. Utility Model Content

[0008] Furthermore, a spray nozzle is installed at the top of the dust settling box, and a water suction pipe is fixedly connected to the bottom of the dust settling box. The other end of the water suction pipe extends to the top of the dust settling box and passes through the top to connect with the spray nozzle. A water pump connected to the water suction pipe is fixedly installed at the top of the dust settling box, and a drain pipe connected to the inside of the dust settling box is fixedly installed at the bottom of the dust settling box. Two sets of filter components are installed inside the dust settling box.
[0009] Furthermore, two openings are provided on the left side of the dust settling box. Two sets of filter components are inserted into the dust settling box through the two openings respectively. The filter components include filter plates and two support plates. The two support plates are symmetrically installed on the front and rear sides of the inner wall of the dust settling box, and both support plates are inclined. The end of the support plate with the higher horizontal height is located at the corresponding opening.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] Please see Figures 1-8 This utility model provides a technical solution: a waste circuit board sorting and dust removal device, including a crushing box 1. A vertical partition 2 is fixedly installed in the middle of the inner cavity of the crushing box 1, and the bottom end of the partition 2 is located at the middle height of the crushing box 1. Two symmetrically distributed crushing rollers 3 are arranged between the left side of the partition 2 and the inner wall of the crushing box 1. A discharge port 8 is opened at the bottom of the right side of the crushing box 1. An inclined feeding plate 9 is installed on the left side of the inner wall of the crushing box 1, located near the crushing rollers 3, and extends to the discharge port 8. A conveying box 10 is set at the top of the crushing box 1. A feeding port located above the crushing rollers 3 is opened at the bottom of the left end of the conveying box 10. A feeding plate 9 is installed on the rear side of the crushing box 1. The material box 10 is equipped with a dust collection box 17. A first dust collection mechanism connected to the dust collection box 17 is set at the top of the left end of the material box 10. A second dust collection mechanism connected to the dust collection box 17 is set inside the crushing box 1 and on the right side of the partition 2. The circuit board can be transported to the two crushing rollers 3 in the crushing box 1 by the conveyor belt 11 inside the material box 10. Then, the dust generated when crushing the circuit board can be collected by the first dust collection mechanism and the second dust collection mechanism, and all the collected dust is introduced into the dust collection box 17. Then, the water mist sprayed by the spray nozzle 22 inside the dust collection box 17 can be used to suppress the dust, thereby achieving effective dust collection and treatment.
[0027] like Figure 2 , Figure 3 and Figure 6As shown, the first dust collection mechanism includes a first dust collection hood 14, a first dust guide pipe 15, and a first dust collection fan 16. The first dust collection hood 14 is fixedly installed on the top of the left end of the conveying box 10. The first dust guide pipe 15 is fixedly connected to the top of the first dust collection hood 14, and the other end of the first dust guide pipe 15 is fixedly connected to the top of the left side of the dust settling box 17. The first dust collection fan 16 is installed at the opening at the end of the first dust guide pipe 15 that connects to the first dust collection hood 14. The end of the first dust guide pipe 15 that connects to the dust settling box 17 is inclined downwards. The first dust collection mechanism can collect the dust generated when the circuit board is broken. The dust that rises during the circuit board breaking process is drawn by the suction of the first dust collection fan 16 and enters the dust settling box 17 through the first dust collection hood 14 and the first dust guide pipe 15. The dust that enters the dust settling box 17 will combine with the water mist sprayed by the spray nozzle 22, thereby completing the dust settling treatment.
[0028] like Figure 2 , Figure 3 and Figure 6 As shown, the second dust collection mechanism includes a second dust collection hood 19, a second dust guide pipe 20, and a second dust collection fan 21. The second dust collection hood 19 is fixedly installed between the bottom right side of the partition 2 and the inner wall of the crushing box 1. The second dust guide pipe 20 is fixedly connected to the top of the second dust collection hood 19. The other end of the second dust guide pipe 20 passes through the rear side of the crushing box 1 and is fixedly connected to the top right side of the dust settling box 17. The second dust collection fan 21 is installed at the opening of the second dust guide pipe 20 connected to the second dust collection hood 19. The end of the second dust guide pipe 20 connected to the dust settling box 17 is inclined downwards. The second dust collection mechanism can collect circuit board fragments in... Dust generated when sliding on the feed plate 9 is collected. The dust is drawn by the suction of the second dust suction fan 21 and enters the dust settling box 17 through the second dust collection hood 19 and the second dust guide pipe 20. The dust entering the dust settling box 17 will also combine with the water mist sprayed by the spray nozzle 22, thereby completing the dust settling process. The ends of the first dust guide pipe 15 and the second dust guide pipe 20 that connect to the dust settling box 17 are set to be inclined downwards, which can prevent the sprayed water mist from flowing into the first dust guide pipe 15 and the second dust guide pipe 20. Some of the water mist that enters the first dust guide pipe 15 and the second dust guide pipe 20 will flow back into the dust settling box 17 along the slope.
[0029] like Figure 2 , Figure 6 and Figure 7As shown, a spray nozzle 22 is installed at the top of the inner cavity of the dust settling box 17. A water suction pipe 23 is fixedly connected to the bottom of the dust settling box 17, and the other end of the water suction pipe 23 extends to the top of the dust settling box 17 and passes through it to connect with the spray nozzle 22. A water pump 24 connected to the water suction pipe 23 is fixedly installed at the top of the dust settling box 17, and a drain pipe 27 connected to the inside of the dust settling box 17 is fixedly installed at the bottom of the dust settling box 17. Two sets of filter components are installed inside the dust settling box 17. By operating the water pump 24, the water suction pipe 23 draws water from the bottom of the inner cavity of the dust settling box 17, and then the water is sprayed out from the spray nozzle 22, thereby performing dust settling treatment on the dust that enters the dust settling box 17. After the dust and water mist combine, they re-gather in the water below, while the two filter components can intercept the dust in the water, thereby preventing the dust from settling to the bottom of the water and thus preventing the dust from entering the water suction pipe 23.
[0030] like Figure 2 , Figure 6 and Figure 7 As shown, two openings are provided on the left side of the dust settling box 17. Two sets of filter components are inserted into the dust settling box 17 through the two openings respectively. The filter components include filter plates 25 and two support plates 26. The two support plates 26 are symmetrically installed on the front and rear sides of the inner wall of the dust settling box 17, and both support plates 26 are inclined. The end of the support plate 26 with the higher horizontal height is located at the corresponding opening. The filter plate 25 is inserted into the opening and is located on top of the two support plates 26. The part of the filter plate 25 inside the dust settling box 17 is set as a filter screen. A handle is installed on the end of the filter plate 25 outside the dust settling box 17. The filter plates 25 are inserted vertically and parallel inside the dust settling box 17. When cleaning the filter plates 25, the handle at the end of the filter plate 25 can be pulled to remove it from the opening on the side of the dust settling box 17. When the upper filter plate 25 is removed, the lower filter plate 25 can continue to intercept dust. After cleaning the upper filter plate 25 and reinserting it into the dust settling box 17, the lower filter plate 25 can be removed and cleaned. The support plate 26 can provide support at the bottom of the filter plates 25. The filter plates 25 are set at an angle inside the dust settling box 17, which allows more water to be stored inside the dust settling box 17.
[0031] like Figure 1 , Figure 3 and Figure 4As shown, the shafts at both ends of the two crushing rollers 3 are rotatably inserted into the inner wall of the crushing box 1. The shafts at one end of each crushing roller 3 pass through the front side of the crushing box 1. Gears 4 are fixedly installed on the shafts of the two crushing rollers 3 located outside the crushing box 1. The two gears 4 are meshed together. A fixing frame 5 covering the gears 4 is fixedly installed on the front side of the crushing box 1. A first motor 6 is installed on the fixing frame 5. The output end of the first motor 6 is fixedly connected to the shaft of one of the gears 4. Downward-inclined... The inclined guide plates 7 have their bottom ends located on top of the two crushing rollers 3, respectively. The mounting bracket 5 provides a mounting position for the first motor 6. Running the first motor 6 can drive one of the gears 4 to rotate, and then the rotating gear 4 drives the other gear 4 that meshes with it to rotate, thereby driving the two crushing rollers 3 to rotate simultaneously. In this way, the crushing rollers 3 can crush the waste circuit boards that fall between them. Under the action of the two guide plates 7, the waste circuit boards can slide smoothly between the two crushing rollers 3.
[0032] like Figure 1 , Figure 3 and Figure 8 As shown, a discharge port is provided at the right end of the feeding box 10. A conveyor belt 11 is provided at the right end of the feeding box 10, and the left end of the conveyor belt 11 is located at the discharge port. A second motor 12 is fixedly installed on the front side of the feeding box 10. The output end of the second motor 12 is connected to the rotating shaft at the left end of the conveyor belt 11. A baffle 13 is provided inside the feeding box 10 and above the left end of the conveyor belt 11. A rod shaft is fixedly installed at the top of the baffle 13. The two ends of the rod shaft are respectively rotatably inserted into the two sides of the inner wall of the feeding box 10. By operating the second motor 12, the conveyor belt 11 can be driven to rotate inside the feeding box 10, and the material to be crushed is transported to the feeding box 10. The shredded waste circuit boards are placed on the conveyor belt 11. The operation of the conveyor belt 11 can transport the circuit boards to the two crushing rollers 3 inside the crushing box 1. The baffle 13 can block the spread of dust and prevent the dust generated during the crushing of the circuit boards from spreading out from the right end of the feeding box 10. When the circuit boards transported on the conveyor belt 11 reach the discharge port, the circuit boards will press against the bottom of the baffle 13 and push the baffle 13, causing the baffle 13 to flip around its top rod axis. This will not affect the normal transport of the circuit boards and allow the circuit boards to fall smoothly between the two crushing rollers 3.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
