[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figures 1 to 5 As shown, a circuit board processing waste processing device of the present invention includes a box body 1, a feeding channel 2 is provided at one end of the top of the box body 1, a first conveyor belt 3 is provided at the bottom of the inner wall of the feeding channel 2, one end of the first conveyor belt 3 extends into the interior of the box body 1, a water spray pipe 4 is provided inside the feeding channel 2 and above the first conveyor belt 3, two crushing rollers 5 are rotatably connected to the inside of the box body 1 and below the output end of the first conveyor belt 3, a second conveyor belt 6 is provided below the crushing roller 5, a drying chamber 7 is provided at one end of the box body 1, the output end of the second conveyor belt 6 extends into the interior of the drying chamber 7, a third conveyor belt 8 is provided below the second conveyor belt 6, and a plurality of electromagnets 9 are installed on the surface of the third conveyor belt 8;

[0027] In this embodiment, first, the staff puts the circuit board waste to be processed into the first conveyor belt 3 in the feeding channel 2. Under the transmission of the first conveyor belt 3, the circuit board will move toward the box body 1. During this process, the circuit board will pass under the water spray pipe 4. At this time, the staff can input water into the water spray pipe 4, so that the water will be sprayed from the water spray pipe 4 to wet the circuit board. After passing through the water spray pipe 4, the circuit board will be transported by the first conveyor belt 3 to between the two crushing rollers 5. Under the action of the two crushing rollers 5, the circuit board can be crushed. Since the circuit board is wetted in advance, the dust generated during the crushing process will be relatively small. The water spray pipe 4 is set in the feeding channel 2. This reduces the amount of dust in the box 1 that is dispersed to the outside, significantly improving the surrounding air quality and providing a cleaner and healthier working environment. The crushed circuit boards will fall onto the second conveyor belt 6 and enter the drying chamber 7 for drying under the transmission of the second conveyor belt 6. The dried circuit board particles can be more convenient in the subsequent screening process. The dried circuit board particles will fall onto the third conveyor belt 8 under the transmission of the second conveyor belt 6. At this time, the metal particles in the circuit board particles will be adsorbed by the electromagnet 9 on the third conveyor belt 8. In this way, the third conveyor belt 8 can transport the metal particles and non-metallic particles to different positions for discharge, thereby achieving the screening effect.

[0028] like Figure 4 As shown, one end of the top of the feed channel 2 is connected to the feed hopper 10, and the end of the feed channel 2 adjacent to the feed hopper 10 is fixedly connected to a water pump 11. The output end of the water pump 11 is connected to the water spray pipe 4 through a connecting pipe 12, and a plurality of atomizing nozzles 13 are installed at the bottom of the water spray pipe 4;

The atomizing nozzle 13 can convert water into extremely fine droplets. The diameter of these droplets is very small, thereby increasing the contact area with the dust particles in the air. Such fine droplets are more easily adsorbed, collided and combined with dust particles, thereby improving the dust reduction efficiency.

[0030] like Figure 1 As shown, one end of the outer wall of the feed channel 2 is fixedly connected to the first motor 14, and the output end of the first motor 14 is fixedly connected to the input shaft of the first conveyor belt 3;

[0031] In this embodiment, the first motor 14 is designed to provide driving force for the rotation of the first conveyor belt 3 .

[0032] like Figure 2As shown, two gears 15 are fixedly connected to one end of the outer wall of the box body 1, and the two gears 15 are meshed with each other and are fixedly connected to the two crushing rollers 5 respectively;

[0033] In this embodiment, the design of the two gears 15 allows the two crushing rollers 5 to rotate synchronously in opposite directions, thereby facilitating crushing of the circuit board.

[0034] like Figure 1 and Figure 3 As shown, a crushing motor 16 is fixedly connected to the side wall of the box body 1 away from the gear 15, and the output end of the crushing motor 16 is fixedly connected to one of the crushing rollers 5. The box body 1 is fixedly connected to the first brush plate 17 at the adjacent positions of the two crushing rollers 5;

[0035] In this embodiment, the design of the pulverizing motor 16 is used to increase the driving force for the rotation of the pulverizing roller 5 , and the design of the first brush plate 17 allows the particles attached to the pulverizing roller 5 to be brushed off, thereby ensuring the pulverizing effect of the pulverizing roller 5 .

[0036] like Figure 1 and 5 As shown, a second motor 18 is fixedly connected to one end of the outer wall of the box body 1, and the output end of the second motor 18 is fixedly connected to the input shaft of the second conveyor belt 6. A dryer 19 is installed on the top of the drying chamber 7, and a second brush plate 20 is fixedly connected to the inside of the drying chamber 7 below the second conveyor belt 6;

[0037] In this embodiment, the second motor 18 is designed to provide driving force for the rotation of the second conveyor belt 6, the dryer 19 is designed to dry the wet circuit board particles to facilitate subsequent screening, and the second brush plate 20 is designed to brush off the circuit board particles attached to the second conveyor belt 6.

[0038] like Figures 1 to 3 As shown, the box body 1 is provided with a first discharge port 21 at the output end of the third conveyor belt 8, one end of the first discharge port 21 extends below the third conveyor belt 8, and one end of the outer wall of the box body 1 is fixedly connected to a third motor 22, and the output end of the third motor 22 is fixedly connected to the input shaft of the third conveyor belt 8;

[0039] In this embodiment, the design of the first discharge port 21 facilitates the discharge of non-metallic particles on the third conveyor belt 8, and the design of the third motor 22 provides driving force for the rotation of the third conveyor belt 8.

[0040] like Figures 1 to 3As shown, a second discharge port 23 is provided on the side wall of the box body 1 away from the first discharge port 21, and a guide plate 24 is fixedly connected to the inner wall of the box body 1 at the second discharge port 23. The guide plate 24 is tilted, and a cleaning roller 25 is rotatably connected to the inner wall of the box body 1 above the guide plate 24. A plurality of bristles are provided on the surface of the cleaning roller 25. A fourth motor 26 is fixedly connected to one end of the outer wall of the box body 1, and the output end of the fourth motor 26 is fixedly connected to the cleaning roller 25.

[0041] In this embodiment, after the third conveyor belt 8 discharges the non-metallic particles, the metal particles will still be attached to the electromagnet 9 of the third conveyor belt 8 and move to the lower end of the third conveyor belt 8. When the electromagnet 9 with the metal particles attached moves above the guide plate 24, the power supply of the electromagnet 9 is turned off, so that the electromagnet 9 loses its magnetism, and the metal particles fall onto the guide plate 24 and are discharged from the second discharge port 23 along the guide plate 24. During this process, the fourth motor 26 is turned on, and the cleaning roller 25 is driven by the fourth motor 26 to rotate, thereby brushing off the metal particles attached to the third conveyor belt 8.

[0042] Working principle: First, the staff puts the circuit board waste to be processed into the first conveyor belt 3 in the feed channel 2 through the feed hopper 10. At this time, the first motor 14 is turned on. Under the drive of the first motor 14, the first conveyor belt 3 will rotate to convey the circuit board. During this process, the circuit board will pass under the water spray pipe 4. At this time, the water pump 11 is turned on to input water flow into the water spray pipe 4, so that the water flow is sprayed from the atomizing nozzle 13 at the bottom of the water spray pipe 4, thereby wetting the circuit board. After passing through the water spray pipe 4, the circuit board will be transported by the first conveyor belt 3 to between the two crushing rollers 5. At this time, the crushing motor 16 is turned on. Open, so that the two crushing rollers 5 can rotate. Under the action of the two crushing rollers 5, the circuit board can be crushed. Since the circuit board is wetted in advance, the dust generated during the crushing process will be relatively small. The water spray pipe 4 is set in the feeding channel 2, so as to reduce the dust in the box 1 from drifting to the outside, thereby significantly improving the surrounding air quality and providing a cleaner and healthier working environment for work. The crushed circuit boards will fall onto the second conveyor belt 6. At this time, the second motor 18 is turned on to drive the second conveyor belt 6 to rotate. The circuit board particles are conveyed by the second conveyor belt 6 into the drying chamber 7. At this time, The dryer 19 is turned on to dry the circuit board. The dried circuit board particles can be more convenient in the subsequent screening process. The dried circuit board particles will fall onto the third conveyor belt 8 under the transmission of the second conveyor belt 6. At this time, the metal particles in the circuit board particles will be adsorbed by the electromagnet 9 on the third conveyor belt 8, so that the third conveyor belt 8 can transport the metal particles and non-metallic particles to different positions for discharge. At this time, the third motor 22 is turned on, and the third conveyor belt 8 will rotate under the drive of the third motor 22. When the circuit board particles are transported to the top of the first discharge port 21 by the third conveyor belt 8, the circuit board particles are transported to the top of the first discharge port 21 by the third conveyor belt 8. The non-metallic particles in the plate particles will fall off and be discharged from the first discharge port 21, while the metal particles will still be attached to the electromagnet 9 of the third conveyor belt 8 and move to the lower end of the third conveyor belt 8. When the electromagnet 9 with the metal particles attached moves to above the guide plate 24, the power supply of the electromagnet 9 is turned off, so that the electromagnet 9 loses its magnetism, and the metal particles fall onto the guide plate 24 and are discharged from the second discharge port 23 along the guide plate 24. During this process, the fourth motor 26 is turned on, and the cleaning roller 25 is driven by the fourth motor 26 to rotate, thereby brushing off the metal particles attached to the third conveyor belt 8.

[0043] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible.
