Description

Technical Field

[0001] The present invention relates to the technical field of hazardous waste treatment, and specifically to a circuit board waste treatment and recycling device. Background Art

[0002] With the rapid development of the electronics industry, circuit boards, as an important part of electronic devices, are being produced and updated at an increasingly fast pace. The generation of a large number of waste circuit boards not only occupies valuable land resources but may also cause serious environmental pollution problems due to improper treatment. Waste circuit boards often contain various heavy metals and harmful substances. If directly discarded or simply landfilled, these harmful substances will gradually seep into the soil and water sources, posing a long-term threat to the ecological environment and human health. At the same time, some metal resources contained in circuit boards, such as copper, gold, silver, etc., these metals have high recycling value.

[0003] Traditional circuit board treatment methods, such as incineration, pickling, etc., although can achieve metal recycling to a certain extent, are often accompanied by problems of high energy consumption, high pollution, low metal recovery rate, and low resource utilization efficiency. At the same time, some mechanical recycling devices generally first crush and then classify and process metals and non-metals. However, this method can only achieve simple classification and purification. For circuit boards containing various metal and non-metal impurities, the recycling is not fine enough and cannot achieve precise and efficient recycling.

[0004] Therefore, developing a circuit board crushing, recycling and treatment device with high efficiency, environmental protection and high resource utilization rate has become an urgent need in the current field of electronic waste treatment. The device should be able to finely crush waste circuit boards, effectively separate the metal and non-metal components therein, and at the same time avoid the leakage and secondary pollution of harmful substances, providing strong support for the resource utilization of electronic waste.

[0032] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] Please refer to Figures 1-8 , as an embodiment of the present invention, a circuit board waste treatment and recycling device includes a crushing processing box 6. A crushing processing component is arranged in the crushing processing box 6. The bottom of the crushing processing box 6 is fixedly connected with a filter guide cylinder 10. A filtering component is arranged in the filter guide cylinder 10. The bottom of the filter guide cylinder 10 is fixedly connected with a classification processing cylinder 2. A support rod 11 is fixedly connected between the classification processing cylinder 2 and the filter guide cylinder 10. The top of the crushing processing box 6 is fixedly connected with a feed pipe 12. The feed pipe 12 is communicated with the inside of the crushing processing box 6. The outer wall of the feed pipe 12 is fixedly connected with a mounting frame 13. The bottom of the mounting frame 13 is fixedly connected with the bottom plate 1;

[0034] One side of the inner wall of the classification processing cylinder 2 is fixedly connected with a partition board 18. A non-metal material separation component is arranged on the partition board 18. A rotating component is arranged below the partition board 18. One side of the rotating component is connected with a classification collection plate 24. A plurality of classification collection plates 24 are longitudinally arranged. An electromagnetic material suction plate 23 is fixedly connected to the classification collection plate 24. The bottom of the classification collection plate 24 is fixedly connected with a feed hopper 35. A valve component is arranged on the feed hopper 35. A control switch 38 is arranged on one side of the valve component. The control switch 38 is connected with the electromagnetic material suction plate 23. A recycling component is arranged below the feed hopper 35. A vibrating material lifting component is arranged on the inner wall of the classification processing cylinder 2.

[0035] During actual use, the crushing component can crush the waste circuit board into particles, and then classify and extract the materials through the non-metal material separation component. By using the vibrating material lifting component in cooperation with multiple classification collection plates 24, rapid and accurate classification and recovery of metal particles with different densities can be achieved. Compared with traditional recycling equipment, this method has a higher purification and recovery accuracy, can classify and collect various types of metals, avoids secondary manual sorting, has a higher working efficiency, reduces the manual labor amount, and has a better use effect.

[0036] Please refer to Figures 1-8 As another embodiment of the present invention, the crushing component includes crushing rollers 46 rotatably arranged on both sides inside the crushing treatment box 6. A transmission housing 8 is fixedly connected to the outside of the crushing treatment box 6 on one axial side of the crushing roller 46. A transmission gear 49 is rotatably connected inside the transmission housing 8. The end of the rotating shaft of the transmission gear 49 is fixedly connected to the end of the rotating shaft of the crushing roller 46. The transmission gears 49 are meshed with each other, and a driving motor 7 is fixedly connected to the outside of the transmission housing 8 on one axial side of one of the transmission gears 49. The end of the output shaft of the driving motor 7 is fixedly connected to the end of the rotating shaft of the transmission gear 49. During actual use, the driving motor 7 can drive the two crushing rollers 46 to rotate through the transmission gears 49 to initially crush the waste circuit board.

[0037] A grinding head 44 is rotatably arranged in the crushing treatment box 6 below the crushing roller 46. Grinding teeth 45 are arranged at corresponding positions of the grinding head 44 and the crushing treatment box 6. A grinding motor 27 is fixedly connected to the bottom of the crushing treatment box 6 on one axial side of the grinding head 44. The end of the output shaft of the grinding motor 27 is fixedly connected to the rotating shaft of the grinding head 44. By driving the grinding head 44 to rotate through the grinding motor 27, finer crushing of the crushed circuit board can be achieved under the action of the grinding teeth 45, which is convenient for subsequent fine classification.

[0038] The filtering component includes a filter screen 47 fixedly arranged in the filter guiding cylinder 10. A return material box 15 is arranged on the outer wall of the filter guiding cylinder 10 on one side of the filter screen 47. By arranging the filter screen 47, circuit board waste that is not finely filtered can be filtered out, which does not affect subsequent fine recycling, improves the accuracy and quality of recycling. At the same time, the materials in the return material box 15 can repeat the above crushing steps for secondary treatment and recycling to improve the recycling rate.

[0039] The non-metal material separation component includes a filter frame 17 fixedly arranged on the partition plate 18. An air-permeable filter plate 14 is fixedly connected to the side wall of the classification treatment cylinder 2 on one side of the filter frame 17. A material suction component is arranged on the side wall of the classification treatment cylinder 2 on the side of the filter frame 17 away from the air-permeable filter plate 14. A collection frame 16 is fixedly connected to the partition plate 18 on the side of the filter frame 17 close to the air-permeable filter plate 14.

[0040] The material suction component includes a mounting plate 5 fixedly arranged on the outer wall of the crushing treatment box 6. One side of the mounting plate 5 is fixedly connected to a dust collector 4. The air inlet end of the dust collector 4 is fixedly connected to a dust suction cylinder 9, and the air inlet end of the dust suction cylinder 9 is fixedly connected to the classification treatment cylinder 2. Through the action of the dust collector 4, an air flow can be generated in the classification treatment cylinder 2, and in this case, the recovery of non-metallic materials with relatively low density in the particles can be realized.

[0041] The rotation component includes a mounting motor 50 fixedly arranged at the bottom of the partition plate 18. The bottom of the output shaft of the mounting motor 50 is fixedly connected to a fixed column 34. A sleeve 33 is slidably sleeved on the fixed column 34. The bottom of the fixed column 34 is fixedly connected to a fixed block 32. An electric lifting rod 31 is fixedly connected to the fixed block 32. The top of the electric lifting rod 31 is fixedly connected to the sleeve 33. The sleeve 33 is fixedly connected to the side wall of the classification collection plate 24. In actual use, the mounting motor 50 can drive the sleeve 33 to rotate through the fixed column 34, and then drive the classification collection plate 24 to rotate. During the rotation, since a plurality of classification collection plates 24 on the sleeve 33 are arranged longitudinally, the descending speeds of particulate materials with different densities are also different during the up and down vibration process. When the classification collection plate 24 and the electromagnetic material suction plate 23 rotate to the area where the particulate materials vibrate, the recovery of particulate materials with different densities can be realized. This method can achieve high-precision and rapid classification recovery of metal particulate materials. At the same time, the electric lifting rod 31 can drive the sleeve 33 to move up and down, so that the classification collection plate 24 and the electromagnetic material suction plate 23 can flexibly adjust their positions, and can be flexibly adjusted for use when facing waste materials of different materials, with a larger scope of use.

[0042] The valve component includes a valve column 37 slidably penetrating through the blanking cylinder 35. A valve orifice 36 is opened on the valve column 37. An elastic member 39 is sleeved on the valve column 37 on the outer side of the blanking cylinder 35. The valve column 37 is correspondingly arranged with a control switch 38.

[0043] The recovery component includes a discharge rod 3 fixedly penetrating through the side wall of the classification treatment cylinder 2. A collection shell 29 is slidably penetrating through the discharge rod 3. A fixed frame 30 is fixedly connected to the side wall of the discharge rod 3 above the collection shell 29. A guide plate 28 is fixedly connected to the bottom side wall of the fixed frame 30. The guide plate 28 is correspondingly arranged with the blanking cylinder 35. First electric telescopic columns 25 and second electric telescopic columns 26 are respectively fixedly arranged on the side walls of the fixed frames 30 of the two groups of recovery components. The first electric telescopic column 25 and the second electric telescopic column 26 are correspondingly arranged with the valve component. The telescopic strokes of the first electric telescopic column 25 and the second electric telescopic column 26 are different.

[0044] During actual use, since the magnetic metal adsorbed on the electromagnetic suction plate 23 is located above the non-magnetic metal on the classification and collection plate 24, during the rotation and classification collection of the device, the sleeve 33 drives the blanking cylinder 35 to rotate to a position corresponding to the first electric telescopic column 25. The stroke of the first electric telescopic column 25 is short and can only drive the valve column 37 to move a small displacement. The valve column 37 is not enough to contact the control switch 38. In this case, the non-magnetic metal in the classification and collection plate 24 is first blanked for collection. After the collection is completed, the sleeve 33 continues to rotate to correspond to the second electric telescopic column 26. The longer stroke of the second electric telescopic column 26 can drive the valve column 37 to contact the control switch 38. The control switch 38 controls the power-off of the electromagnetic suction plate 23. After the electromagnetic suction plate 23 loses magnetism, the magnetic metal particles can be recovered through the blanking cylinder 35, thereby realizing the classified recovery of magnetic metal and non-magnetic metal.

[0045] The vibration feeding component includes a vibration feeding plate 19 slidably arranged on the inner wall of the classification and treatment cylinder 2. A telescopic cylinder 20 is arranged between the vibration feeding plate 19 and the bottom plate 1. The telescopic section of the telescopic cylinder 20 is sleeved with a resetting member 48. An electric telescopic rod 21 is fixedly connected to the bottom plate 1 on one side of the vibration feeding plate 19. The telescopic end of the electric telescopic rod 21 is fixedly connected to a mounting head 43. A clamping rod 41 is slidably arranged on one side of the mounting head 43. A telescopic member 42 is fixedly connected between the clamping rod 41 and the inner wall of the mounting head 43. A limiting rod 40 is fixedly connected to the outer wall of the vibration feeding plate 19 on one side of the clamping rod 41. The limiting rod 40 is arranged corresponding to the clamping rod 41. Under the action of the electric telescopic rod 21, the device can realize the vibration of the vibration feeding plate 19 through the cooperation of the clamping rod 41 and the limiting rod 40, thereby driving the vibration of the materials on the vibration feeding plate 19.

[0046] During the implementation of the present invention, the device is started, and the waste circuit board is placed in the feeding pipe 12. The driving motor 7 drives the crushing roller 46 to rotate through the transmission gear 49 to realize the preliminary crushing of the circuit board. The preliminarily crushed material falls to the position of the grinding head 44. Under the action of the grinding motor 27, the grinding teeth 45 on the grinding head 44 realize the secondary grinding of the preliminarily crushed material into particles. Subsequently, the granular waste falls into the filtering and guiding cylinder 10. Under the action of the filter screen 47, the materials that are not thoroughly ground can be filtered out and guided into the recycling box. The granular waste with appropriate size falls into the classification and treatment cylinder 2. When the granular waste falls to a position corresponding to the filtering frame 17, under the action of the dust collector 4, the external air enters the classification and treatment cylinder 2 through the ventilation and filtering plate 14 and is discharged through the dust collector 4. Under the action of this air flow, the lighter impurities such as non-metallic plastics in the waste are filtered on one side of the filtering frame 17. This process realizes the separation of the non-metallic materials in the circuit board;

[0047] Subsequently, the metal particle waste with a larger density continues to fall onto the vibrating material lifting plate 19. Since the metal materials used on the circuit board are also different, the particle densities of different metal materials are also different. Under the action of the electric telescopic rod 21, through the engagement of the clamping rod 41 on one side of the mounting head 43 with the limiting rod 40, when the clamping rod 41 moves downward, it can drive the vibrating material lifting plate 19 to move downward through the limiting rod 40. At this time, the reset member 48 is compressed and stores energy. When in the limit position, the telescopic member 42 is compressed. At this time, the limiting rod 40 loses its limitation, and under the action of the reset member 48, it can drive the vibrating material lifting plate 19 to vibrate, thereby being able to lift the metal particle waste. Considering the action of air resistance, the moving speeds of metal particles with different densities are different. Therefore, each time it vibrates and lifts, the metal particles of different materials are at different heights. Then, under the action of the installed motor 50, the fixed column 34 drives the sorting and collecting plate 24 on one side of the sleeve 33 to rotate. Under the action of the electromagnetic material suction plate 23, it can adsorb magnetic metal materials. For non-magnetic metal materials with different densities, they fall onto the sorting and collecting plate 24. This process is repeated to achieve the precise classification and recycling of different metal materials. After the collection is completed, when the feeding cylinder 35 at the bottom of the sorting and collecting plate 24 rotates to the position corresponding to the first electric telescopic column 25, the first electric telescopic column 25 moves to drive the valve column 37 to move. The valve orifice 36 on the valve column 37 corresponds to the feeding channel of the feeding cylinder 35. Then, the non-magnetic metal materials fall onto the diversion plate 28 to achieve recycling. Subsequently, under the action of the installed motor 50, it continues to drive the sorting and collecting plate 24 on one side of the sleeve 33 to rotate. Under the action of the second electric telescopic column 26, it can drive the valve column 37 to move a greater stroke. The valve column 37 contacts the control switch 38, causing the electromagnetic material suction plate 23 to lose power and magnetism. Then, the magnetic metal materials fall again through the feeding cylinder 35 at the bottom of the sorting and collecting plate 24 to another diversion plate 28 to achieve recycling, and the materials that have not been recycled finally remain on the vibrating material lifting plate 19.

[0048] Generally speaking, this device realizes the multi-level and fine recycling of valuable metal materials, which is convenient for subsequent classification and recycling. Compared with the traditional method, the purification rate is higher, and it can bring greater economic benefits to the enterprise. This method can not only ensure a higher and purer recycling effect, but also produce less pollutants and be more environmentally friendly when using mechanical recycling compared with chemical recycling, and the use effect is better.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
