Description

Technical Field

[0001] The invention relates to the field of waste treatment, and in particular to an electronic device waste treatment device and a treatment method thereof. Background Art

[0002] Electronic device waste is also called electronic product waste. Electronic waste contains a large amount of metal. The shell is generally made of iron, plastic, steel or aluminum. Therefore, plastic, iron, steel, aluminum and other metals can be recycled from electronic waste for secondary use. With the development of science and technology, the output of electronic waste is also increasing. There are four main methods for electronic product waste: chemical treatment, pyrolysis, mechanical treatment and microbial treatment. In the chemical treatment process, the use of strong acid and highly toxic fluoride will produce a large amount of waste liquid and emit toxic gases, which is very harmful to the environment. Pyrolysis is the incineration, melting, sintering and melting of electronic waste, which will also cause serious harm to the environment. From the perspective of resource recovery and ecological environment protection, the two methods are difficult to promote. Although the extraction of gold lamp metal by microbial technology is simple, low-cost and simple to operate, its immersion time is long. Therefore, the mechanical treatment method is currently more widely used. Mechanical treatment of electronic waste is a method of sorting by using the differences in physical properties between the components, including disassembly, crushing, sorting and other steps. After subsequent treatment, the sorted substances can obtain recycled raw materials such as metals and plastics. The disassembly of electronic waste is usually done manually to recover useful electronic components after testing. However, due to the large number of electronic components in electronic waste and the complex combination method, manual processing efficiency is very low.

[0003] Traditional electronic device waste treatment devices require manual secondary sorting after initial crushing, which is not only inefficient, but also poses safety hazards and is likely to cause harm to people. Even electronic device waste treatment devices with screening functions cannot effectively classify linear materials such as data cables and wires during classification, and manual screening of linear waste is still required.

[0016] A method for treating waste electronic devices comprises the following steps:

[0017] S1, placing the electronic device waste to be sorted and processed on the working surface of the conveyor plate, and transporting it to the hollow chamber of the screening box through the conveyor crawler, at this time, the adjustment plate completely covers the discharge hole set at the bottom of the winding working direction 4, so that the winding box can perform corresponding material temporary storage operations;

DETAILED DESCRIPTION

[0029] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0030] The applicant believes that traditional electronic device waste treatment equipment is unable to effectively classify linear materials such as data cables and electrical wires, and requires manual screening of linear waste. At the same time, the waste after initial crushing treatment must be sorted again, which is not only inefficient but also poses a safety hazard.

[0031] To this end, the applicant designed an electronic device waste treatment device that can recycle linear waste, and through the flexible adjustment of the operating mode of the connecting mechanism, the waste can eventually be classified into plastics, metals and other categories for classified discharge operations. While improving the efficiency of electronic device waste treatment, it also avoids the safety hazards of manual operation.

[0032] The electronic device waste treatment device involved in the present invention mainly includes a base 1 for carrying and positioning each component, and further includes two parts: a primary screening component and a material separation and discharge component. Among them, the primary screening component includes a loading mechanism and a screening mechanism; the loading mechanism is placed on one side of the base 1, and is used for material transportation and loading operations; the screening mechanism is connected to the loading mechanism, and is used to receive and preliminarily screen the materials transported by the loading mechanism. The material separation and discharge component includes a connecting mechanism and a classification and discharge mechanism; one end of the connecting mechanism is connected to the screening mechanism, and is used to transmit the materials processed by the screening mechanism; the classification and discharge mechanism is placed below the operating direction of the connecting mechanism, and is used to receive and carry the materials transmitted by the connecting mechanism. The base 1 is hollow and has a predetermined accommodation capacity, and the screening mechanism, the connecting mechanism and the classification and discharge mechanism are all placed in the hollow chamber of the base 1.

[0033] The screening mechanism includes three parts: a screening box 11, a winding component and a driving component 3. One side of the screening box 11 is connected to the material guide plate 2, is hollow and has a predetermined accommodation capacity, and is used to receive the materials conveyed by the conveying plate; the winding component is placed on the upper surface of the screening box 11 in the working direction, and passes through the screening box 11 and extends into the hollow chamber of the screening box 11, and is used to wind and classify linear waste materials; the driving component 3 is placed on one side of the screening box 11, and can provide a predetermined driving force for the overall operation of the screening mechanism.

[0034] The winding component includes four parts: a winding box 4, a telescopic cylinder 5, a stirring rod 6 and a telescopic rod 7. The winding box 4 is placed above the working direction of the screening box 11, is hollow and has a predetermined accommodation capacity, and is used to receive the materials processed by the screening box 11; the telescopic cylinder 5 is placed on the wall surface of the hollow chamber of the winding box 4 in the working direction, and can be telescopically adjusted in a direction perpendicular to the wall surface of the hollow chamber of the winding box 4 in the working direction; the stirring rod 6 is rotatably connected to the end of the telescopic cylinder 5 away from the wall surface of the hollow chamber of the winding box 4 in the working direction through a ball bearing, and can be rotated in all directions around the connection point with the stirring rod while following the adjustment of the telescopic operation of the telescopic cylinder 5 to adjust the working position accordingly; the telescopic rod 7 is placed on the working surface of the stirring rod 6, and can be telescopically adjusted in a direction perpendicular to the stirring rod 6, and can be adjusted in the working position accordingly following the rotation of the stirring rod. In the later operation process, the telescopic adjustment of the telescopic cylinder 5 drives the stirring rod to adjust the corresponding working position between the screening box 11 and the winding box 4; when the telescopic rod 7 is in an extended state, the stirring rod rotates around the connection point with the telescopic cylinder 5, and the telescopic rod 7 follows the rotation of the stirring rod to adjust its position, so as to entangle and stir the linear waste and separate the linear waste.

[0035] A through hole is provided at the connection between the screening box 11 and the winding box 4, so that the stirring rod 6 can extend into the hollow chamber of the screening box 11 through the through hole; the winding box 4 is provided with a blocking plate 8, and the blocking plate 8 is adapted to the size of the winding box 4, and can separate the hollow chamber of the winding box 4; the blocking plate 8 is provided with a material stripping through hole adapted to the stirring rod 6, and the stirring rod 6 can adjust the corresponding working position through the material stripping through hole of the blocking plate 8. The through hole at the connection between the screening box 11 and the winding box 4 is coaxial with the material stripping through hole provided on the blocking plate 8; the working size of the through hole provided at the connection between the screening box 11 and the winding box 4 is larger than the working size of the material stripping through hole provided on the blocking plate 8, and the working size of the material stripping through hole provided on the blocking plate 8 only allows the stirring rod 6 to drive the telescopic rod 7 in the fully retracted state to freely penetrate and adjust. A sliding plate 9 is slidably connected to the through hole between the sieve plate and the winding box 4. The overall operating area of ​​the sliding plate 9 is larger than the overall operating area of ​​the through hole, and the through hole can be completely covered. The operating state of the through hole can be adjusted by sliding the sliding plate 9. The sliding plate 9 is placed at the bottom wall of the hollow chamber of the winding box 4 in the operating direction and is slidably connected to the winding box 4. In the later operation process, when the stirring rod cooperates with the telescopic rod 7 to stir and separate the linear waste, the sliding plate 9 slides in the direction away from the through hole, so that the through hole is in a completely exposed state, and the telescopic cylinder 5 contracts to drive the stirring rod 6 to move into the hollow chamber of the winding box 4, and then the sliding plate 9 slides in the direction close to the through hole to completely cover the through hole, and then the telescopic rod 7 continues to contract to drive the stirring rod to move in the direction close to the material blocking plate 8 and pass through the stripping through hole. Since the size of the stripping through hole only allows the stirring rod to drive the telescopic rod 7 in a fully contracted state to pass freely, the linear waste entangled with the working surface of the stirring rod at the separation will be filtered out and separated, so that it falls into the hollow chamber of the winding box 4, so as to achieve the purpose of linear waste material unloading and recycling. The telescopic cylinder 5, the stirring rod 6 and the telescopic rod 7 can all be driven accordingly by the driving component 3, and can be interconnected with the driving component 3 through circuit connection. The driving component 3 can be a multi-axis motor, and can be driven by multiple motors to drive corresponding components. These are all prior arts and will not be elaborated in the present invention.

[0036] The connection mechanism includes three parts: a fixed block, a rotating block 13 and a connection plate 12. One end of the fixed block is connected to the inner wall of the hollow chamber of the base 1, which is used to limit and fix the overall working position of the connection mechanism; the rotating block 13 is rotatably connected to the fixed block through a ball bearing, and can be rotated and adjusted around the connection point with the fixed block; the connection plate 12 is connected to the rotating block 13, and can follow the rotation of the rotating block 13 to adjust the corresponding working position. The connection point between the connection plate 12 and the rotating block 13 is eccentrically set, and the distance from the end of the connection plate 12 close to the winding material box 4 to the connection point with the rotating block 13 is less than the distance from the end of the connection plate 12 far from the winding material box 4 to the connection point with the rotating block 13. A discharge hole is provided below the working direction of the winding material box 4, and the working state of the discharge hole is controlled by an adjustment plate, which is placed at the bottom wall of the hollow chamber of the winding material box 4 in the working direction and is slidably connected with the fixed block, and the adjustment plate can be driven by an external motor. A sensing switch is provided on the side of the discharge hole away from the connection plate 12, and the distance between the end of the connection plate 12 close to the winding box 4 and the connection point with the rotating block 13 is the distance between the connection point between the rotating block 13 and the connection plate 12 and the sensing switch provided on one side of the discharge hole. In the later operation process, when the connection plate 12 moves toward the direction close to the sensing switch and contacts the sensing switch, the adjustment plate receives the signal of the sensing switch and slides in the direction away from the discharge hole, completely exposing the discharge hole, and performing the corresponding discharge operation.

[0037] The classified discharging mechanism includes two parts: a first recycling box 14 and a second recycling box. The first recycling box 14 is placed below the working direction of the connecting mechanism and has a predetermined distance from the connecting mechanism. It is hollow and has a predetermined accommodation capacity, and can carry the materials transported through the connecting plate 12; the second recycling box is connected to the first recycling box 14 and has a predetermined distance from the connecting mechanism. It is hollow and has a predetermined accommodation capacity, and can carry the materials transported through the connecting plate 12. The first recycling box 14 and the second recycling box can be connected to the connecting plate 12 in a predetermined working state. The ends of the first recycling box 14 and the second recycling box close to the connecting plate 12 are both open and used to receive materials. The overall working height of the first recycling box 14 is higher than that of the second recycling box, and the working surfaces of the first recycling box 14 and the second recycling box are also provided with induction switches. The distance from the end of the connecting plate 12 away from the winding box 4 to the connection point with the rotating block 13 is greater than or equal to the distance from the connection point between the connecting plate 12 and the rotating block 13 to the induction switch set in the second recycling box. The overall operating height of the first recycling box 14 is higher than the distance between the lowest point of the connecting plate 12 and the lowest point of the first recycling box 14 in the operating direction when the connecting plate 12 is in the vertical state. In the later operation process, when the connecting plate 12 rotates to move toward the direction of the induction switch provided on the operating surface of the second recycling box and contacts the induction switch on the operating surface of the second recycling box, the adjustment plate receives the signal again and slides in the direction away from the discharge hole, completely exposing the discharge hole, and performing the corresponding discharge operation again. Each induction switch and the adjustment plate can be connected to each other through wireless signals, which is a prior art and will not be elaborated in the present invention.

[0038] An electromagnetic rotating plate 17 is provided in the hollow receiving chamber of the second recycling box, and the electromagnetic rotating plate 17 divides the second recycling box into a waste recovery chamber 16 and a metal recovery chamber 15; one end of the electromagnetic rotating plate 17 is connected to the bottom inner wall of the second recycling box hollow receiving chamber in the working direction through a rotating block 18, and is perpendicular to the bottom wall of the second recycling box hollow chamber in the working direction, and can be fully rotated in the second recycling box hollow receiving chamber to perform corresponding magnetic suction classification operations. The electromagnetic rotating plate 17 can perform corresponding electromagnetic suction operations through an external motor, and can simultaneously drive the rotating block 18 and the electromagnetic rotating plate 17 through a dual-axis motor. In the later operation process, when the induction switch provided in the second recycling box senses the disconnection between the connecting plate 12 and the connecting plate 12, the electromagnetic rotating plate 17 receives the signal to perform the electromagnetic suction operation, and then the rotating block 18 rotates to drive the electromagnetic rotating plate 17 to rotate into the metal recovery chamber 15, and then the electromagnetic rotating plate 17 is powered off, and the metal waste adsorbed by the electromagnetic rotating plate 17 falls into the metal recovery chamber 15, completing the metal waste recovery operation.

[0039] The feeding mechanism includes two parts: a guide plate 2 and a conveyor plate. The guide plate 2 is placed on one side of the base 1 and passes through the base 1 to be connected to the material screening mechanism; the conveyor plate is placed on the working surface of the guide plate 2 and is covered with a conveyor belt for transporting materials; an open through hole is provided at the connection between the base 1 and the guide plate 2, and the guide plate 2 extends into the receiving chamber of the base 1 through the open through hole and is connected to the material screening box 11.

[0040] The inner wall surface of the hollow chamber of the screening box 11 is covered with an electrostatic adsorption plate, which is connected to the circuit of the driving component 3, and the corresponding operation state can be controlled and adjusted by the driving component 3; a line recovery box 10 is provided on one side of the winding box 4, and a through hole is provided at the connection between the winding box 4 and the line recovery box 10, so that the winding box 4 and the line recovery box 10 are connected to each other, so that the line recovery box 10 can recycle and carry the linear waste processed by the winding box 4. The bottom plate of the winding box 4 is inclined, and the working height of the end of the bottom plate of the winding box 4 close to the line recovery box 10 is lower than the working height of the end of the bottom plate of the winding box 4 away from the line recovery box 10. The line recovery box 10 is placed at the end of the bottom plate of the winding box 4 with a lower working height, so that when the linear waste falls during the later operation process, it can slide along the bottom plate of the winding box 4 with a predetermined inclination to the line recovery box 10 for recycling.

[0041] In the later operation process, a discharge hole can be opened at the bottom position of the second recovery box, the line recovery box 10, and the waste recovery chamber 16 and the metal recovery chamber 15 in the operating direction to discharge and recover the electronic device waste after classification and processing, so as to facilitate subsequent re-processing.

[0042] Based on the above-mentioned electronic device waste treatment device, the present invention proposes a treatment method for the electronic device waste treatment device, and the specific steps are as follows:

[0043] First, the electronic device waste to be sorted is placed on the working surface of the conveyor plate, and transported to the hollow chamber of the screening box 11 by the conveyor belt. At this time, the adjustment plate completely covers the discharge hole at the bottom of the winding box 4 in the working direction, so that the winding box 4 can perform corresponding material temporary storage operations.

[0044] Next, the telescopic cylinder 5 starts to extend in the direction close to the screening box 11, driving the stirring rod 6 to pass through the through holes of the winding box 4 and the screening box 11, so that the stirring rod 6 is placed in the hollow chamber of the screening box 11, and the bottom end of the stirring rod 6 in the working direction contacts the bottom plate of the screening box 11 in the working direction. Then the stirring rod rotates around the connection point with the telescopic cylinder 5, driving the telescopic rod 7 to adjust its position. At this time, the telescopic rod 7 is in a fully extended state, winding and separating the linear waste in the waste; at the same time, the electrostatic adsorption plate covered on the inner wall surface of the hollow chamber of the screening box 11 is started to adsorb the plastic waste in the material. When the stirring rod stops rotating for a predetermined time, the telescopic cylinder 5 starts to retract in the direction away from the screening box 11, driving the stirring rod 6 to move in the direction of the winding box 4, so that the stirring rod 6 is placed in the hollow chamber of the winding box 4, and then the sliding plate 9 is adjusted to completely cover the through hole between the screening box 11 and the winding box 4. The telescopic rod 7 retracts, and when the telescopic rod 7 is in a fully retracted state, the telescopic cylinder 5 starts to retract in the direction away from the winding box 4, driving the stirring rod 6 through the stripping hole provided by the blocking plate 8. Since the size of the stripping hole only allows the stirring rod 6 to drive the telescopic rod 7 in a fully retracted state to freely penetrate and adjust, the linear waste wrapped around the working surface of the stirring rod 6 falls off and falls to the bottom plate of the winding box 4, and slides through the bottom plate of the winding box 4 into the line recovery box 10. The above steps can be repeated many times to ensure the complete recovery of linear waste.

[0045] Subsequently, the electrostatic adsorption plate covering the inner wall surface of the hollow chamber of the screening box 11 is activated to adsorb the plastic waste in the material, and the connecting plate 12 moves toward the discharge hole of the screening box 11. When the connecting plate 12 contacts the induction switch provided at the discharge hole of the screening box 11, the other end of the connecting plate 12 can extend into the waste recovery chamber 16, and then the adjusting plate slides to completely expose the discharge hole, and the waste is transported to the waste recovery chamber 16 via the connecting plate 12.

[0046] Then the connecting plate 12 rotates again, rotating in the direction close to the first recycling box 14. When the connecting plate 12 contacts the induction switch of the first recycling box 14, the electrostatic adsorption plate is powered off, so that the adsorbed plastic waste can pass through the discharge port and fall into the first recycling box 14 under the guidance of the connecting plate 12, completing the recycling of plastic waste. Since the connection point between the connecting plate 12 and the rotating block 13 is eccentrically set, when the connecting plate 12 contacts the induction switch of the first recycling box 14, the operating height of the end of the connecting plate 12 close to the screening box 11 is higher than the operating height of the discharge hole, which can avoid the splashing of materials and ensure that the materials can fall into the first recycling box 14.

[0047] When the induction switch provided on the second recycling box senses that the connecting plate 12 is moving away, the electromagnetic rotating plate 17 is started to adsorb and separate the metal waste in the waste recovery chamber 16, and then the electromagnetic rotating plate 17 rotates the working surface adsorbed with the metal waste into the metal recovery chamber 15 under the rotation of the rotating block 18. When the working surface of the electromagnetic rotating plate 17 adsorbing the metal waste is completely rotated into the metal recovery chamber 15, the electromagnetic rotating plate 17 is powered off, so that the metal waste falls into the metal recovery chamber 15, completing the metal waste recovery operation.

[0048] The circuit connection and signal connection methods between the driving source and various components described in the present invention are all existing technologies, and the driving source mentioned in the present invention is only a partial driving source, which will not be described in detail in the present invention.

[0049] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.

5. A method for treating waste electronic devices according to claim 4, characterized in that The following steps are involved: S1, placing the electronic device waste to be sorted and processed on the working surface of the conveyor plate, and transporting it to the hollow chamber of the screening box (11) through the conveyor crawler, at which time the sliding plate (9) completely covers the discharge hole provided at the bottom of the winding box (4) in the working direction, so that the winding box (4) performs the corresponding material temporary storage operation; S2, the telescopic cylinder (5) is started to extend in a direction close to the screening box (11), driving the stirring rod (6) to pass through the through holes of the winding box (4) and the screening box (11), so that the stirring rod (6) is placed in the hollow chamber of the screening box (11), and the bottom end of the stirring rod (6) in the working direction contacts the bottom plate of the screening box (11) in the working direction; S3, the stirring rod (6) rotates around the connection point with the telescopic cylinder (5), driving the telescopic rod (7) to adjust its position. At this time, the telescopic rod (7) is in a fully extended state, and the linear waste in the waste is wound and separated; when the stirring rod (6) stops rotating after a predetermined period of time, the telescopic cylinder (5) starts to retract in the direction away from the screening box (11), driving the stirring rod (6) to move in the direction of the winding box (4), so that the stirring rod (6) is placed in the hollow chamber of the winding box (4), and then the sliding plate (9) is slidably adjusted to align the screening box (11) with the winding box ( 4); the telescopic rod (7) performs a contraction operation. When the telescopic rod (7) is in a fully contracted state, the telescopic cylinder (5) starts to contract again in a direction away from the winding box (4), driving the stirring rod (6) to pass through the stripping hole provided on the blocking plate (8). Since the size of the stripping hole only allows the stirring rod (6) to drive the telescopic rod (7) in a fully contracted state to freely penetrate and adjust, the linear waste material wrapped around the working surface of the stirring rod (6) falls off and falls to the bottom plate of the winding box (4), and slides through the bottom plate of the winding box (4) into the line recovery box (10); S4, the electrostatic adsorption plate covered on the inner wall surface of the hollow chamber of the screening box (11) is activated to adsorb the plastic waste in the material; the connecting plate (12) moves in a direction close to the discharge hole of the screening box (11), and when the connecting plate (12) contacts the induction switch provided at the discharge hole of the screening box (11), the other end of the connecting plate (12) extends into the waste recovery chamber (16), and then the sliding plate (9) slides to completely expose the discharge hole, and the waste is transported to the waste recovery chamber (16) via the connecting plate (12); S5, the connecting plate (12) rotates again, in a direction approaching the first recycling box (14); when the connecting plate (12) contacts the first recycling box (14), the electrostatic adsorption plate is powered off, so that the adsorbed plastic waste passes through the discharge port and falls into the first recycling box (14) under the guidance of the connecting plate (12), thereby completing the recycling operation of the plastic waste; when the connecting plate (12) moves away from the second recycling box, the electromagnetic rotating plate (17) is started to adsorb and separate the metal waste in the waste recovery chamber (16); then, driven by the rotation of the rotating block (18), the electromagnetic rotating plate (17) rotates the working surface adsorbing the metal waste into the metal recovery chamber (15); when the working surface of the electromagnetic rotating plate (17) adsorbing the metal waste is completely rotated into the metal recovery chamber (15), the electromagnetic rotating plate (17) is powered off, so that the metal waste falls into the metal recovery chamber (15), thereby completing the recycling operation of the metal waste; S6. Repeat steps S1 to S5 in sequence until the waste electrical appliances to be processed are completely processed.
