Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle parts, and particularly relates to a classification and recycling device for disassembled parts of new energy vehicles. Background Art

[0002] The new energy vehicle industry has developed rapidly and the ownership has increased sharply. After the vehicles are scrapped, a large number of waste parts are generated, such as batteries, motors, etc., which contain many recyclable resources. Classifying and recycling these parts has both resource value and environmental protection significance.

[0003] The recycling process of disassembled parts of new energy vehicles generally includes the following steps: performing pretreatment operations such as crushing and impurity removal on the disassembled parts, then using a vibrating screen to preliminarily screen the materials according to the particle size, and then feeding the materials after vibrating screening into a pneumatic separator to perform pneumatic separation according to the characteristics such as the density and shape of the materials, and then feeding the materials after pneumatic separation into a magnetic separator (magnetic drum) to classify magnetic materials and non-magnetic materials;

[0004] However, the magnetic field distribution of the existing magnetic drum on the surface of the conveyor belt is not completely uniform. In some areas, the magnetic field intensity is too high. Once large magnetic materials enter these strong magnetic field areas, they will be firmly attached to the conveyor belt by a strong adsorption force, and a small part of non-magnetic materials will be sandwiched between the magnetic materials on the conveyor belt. In this way, the non-magnetic materials will move to the demagnetization area along with the magnetic materials and thus fall into the magnetic material recycling box, resulting in the problem of incomplete classification and recycling. Based on this, the present invention purposefully provides a classification and recycling device for disassembled parts of new energy vehicles that can classify magnetic materials and non-magnetic materials thoroughly. Summary of the Invention

[0005] The purpose of the present invention is to provide a classification and recycling device for disassembled parts of new energy vehicles in view of the deficiencies of the prior art to solve the technical problems in the prior art.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A classification and recycling device for disassembled parts of new energy vehicles, comprising:

[0008] A base, on which a first bracket, a second bracket and a carrier are fixedly installed. A first conveyor belt is arranged on the first bracket, and the first conveyor belt is driven by a magnetic drum to rotate. The magnetic drum is driven by a drive source arranged on the first bracket to rotate. A second conveyor belt is arranged on the second bracket, and the output end of the first conveyor belt faces the second conveyor belt. The first conveyor belt is used for conveying mixed materials;

[0009] Trapezoidal block, the trapezoidal block is slidably installed on the carrier, the trapezoidal block is driven to move by a driving component built in the carrier, an electromagnetic plate is arranged on the inclined side of the trapezoidal block, the electromagnetic plate is arranged obliquely, the horizontal height of the feeding end of the electromagnetic plate is higher than the horizontal height of the discharging end, the magnetic roller is located above the electromagnetic plate, a first recovery box and a second recovery box are fixedly installed on the base, and the discharging end of the electromagnetic plate faces the first recovery box;

[0010] Expansion member, the expansion member is fixedly installed on the base, the movable end of the expansion member is fixedly installed with a push plate, the push plate is slidably matched with the electromagnetic plate. When the driving component drives the trapezoidal block to move, the demagnetization area of the magnetic roller faces the feeding end of the electromagnetic plate, and the electromagnetic plate is turned on. At this time, the discharging end of the electromagnetic plate faces the first recovery box. When the driving component drives the trapezoidal block to move, the electromagnetic plate is matched with the second recovery box. At this time, the push plate is aligned with the electromagnetic plate, and the expansion member drives the push plate to move to push the magnetic materials adsorbed on the electromagnetic plate into the second recovery box;

[0011] When the driving component drives the trapezoidal block to move and the electromagnetic plate is matched with the second recovery box, the trapezoidal block blocks the first recovery box at this time;

[0012] The number of the electromagnetic plates is two, and the two electromagnetic plates are symmetrically arranged on the two inclined sides of the trapezoidal block. Each electromagnetic plate has a corresponding first recovery box, second recovery box and expansion member. When the driving component drives the trapezoidal block to move and the demagnetization area of the magnetic roller faces the feeding end of one electromagnetic plate, the other electromagnetic plate is matched with the second recovery box at this time.

[0013] As a further scheme of the present invention: a scraper is fixedly installed on the first bracket, the scraper is attached to the surface of the first conveyor belt, and the contact point between the two is located in the demagnetization area of the magnetic roller.

[0014] As a further scheme of the present invention: a baffle extended platform is fixedly installed on the first recovery box. When the trapezoidal block blocks the first recovery box, the discharging end of the electromagnetic plate faces the baffle extended platform, the push plate is slidably matched with the baffle extended platform, and the expansion member drives the push plate to push the magnetic materials on the electromagnetic plate and the baffle extended platform into the second recovery box.

[0015] As a further scheme of the present invention: when the discharging end of the electromagnetic plate faces the baffle extended platform, the electromagnetic plate is turned off.

[0016] As a further solution of the present invention: side baffles are rotatably installed on the trapezoidal block, and the side baffles are driven to rotate by the built-in output source of the trapezoidal block. There is a corresponding side baffle on both sides of each electromagnetic plate. When the demagnetization zone of the magnetic roller is toward the feeding end of the electromagnetic plate, the side baffle corresponding to the electromagnetic plate rotates to form a feeding channel on the electromagnetic plate, and the width of the feeding channel at the discharge end is smaller than the width of the entrance of the first recovery box; before the electromagnetic plate and the push plate slide together, the side baffles rotate away from the electromagnetic plate.

[0017] As a further solution of the present invention: when the telescopic member contracts, a gap is formed between the push plate and the trapezoidal block, and the gap allows the side baffle to rotate away from the electromagnetic plate.

[0018] Beneficial effects of the present invention:

[0019] 1. In the present invention, when a small amount of non-magnetic material mixed in the magnetic material falls onto the electromagnetic plate below the magnetic roller, the electromagnetic plate is in an open state at this time, and the magnetic material is adsorbed on the electromagnetic plate, while a small amount of non-magnetic material will slide along the inclined plate surface of the electromagnetic plate and fall into the first recycling box, and then the driving component drives the trapezoidal block to move on the carrier, so that the electromagnetic plate and the second recycling box cooperate, and then the telescopic part drives the push plate, and the push plate pushes the magnetic material adsorbed on the electromagnetic plate into the second recycling box, thus completing the secondary classification and recycling process, further ensuring the purity of the magnetic material. In this process, the non-magnetic material originally entrained by the magnetic material into the demagnetization zone is completely removed, and the deep separation of the magnetic material and the non-magnetic material is achieved;

[0020] 2. In the present invention, the arrangement of the electromagnetic plate allows the magnetic force generated by the electromagnetic plate to attract the magnetic materials on the surface of the first conveyor belt, which, on the one hand, assists the magnetic materials moved to the demagnetization area of ​​the magnetic roller for unloading, and on the other hand, accelerates the falling of the magnetic materials, so that the unloading speeds of the magnetic materials and the non-magnetic materials are different. The magnetic materials are first adsorbed on the electromagnetic plate, and the non-magnetic materials will slide along the inclined surface of the electromagnetic plate into the first recycling box for classification;

[0021] 3. In the present invention, through the design of two electromagnetic plates, when one electromagnetic plate is below the demagnetization zone of the magnetic roller, it is performing secondary classification and processing. When the electromagnetic plate is full of magnetic materials, unloading operation is required. Therefore, the driving component drives the trapezoidal block to move so that the electromagnetic plate full of magnetic materials cooperates with the second recycling box to unload materials. At the same time, the other electromagnetic plate moves to a position that cooperates with the demagnetization zone of the magnetic roller. At this time, the secondary classification and processing can continue. In this way, the purpose of continuous operation without stopping is achieved, thereby improving the efficiency of classification and processing of new energy vehicle parts.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0031] Please refer to Figures 1-6 as shown, the present invention is a device for classifying and recycling disassembled parts of new energy vehicles, including:

[0032] Base 1, on which a first bracket 101, a second bracket 102 and a carrier 103 are fixedly installed. A first conveyor belt 2 is arranged on the first bracket 101, and the first conveyor belt 2 is driven by a magnetic drum 3 to rotate. The magnetic drum 3 is driven by a driving source arranged on the first bracket 101 to rotate. A second conveyor belt 4 is arranged on the second bracket 102. The output end of the first conveyor belt 2 faces the second conveyor belt 4. The first conveyor belt 2 is used for conveying mixed materials;

[0033] Trapezoidal block 5, the trapezoidal block 5 is slidably mounted on the carrier 103, the trapezoidal block 5 is driven to move by a driving component built in the carrier 103, an electromagnetic plate 501 is arranged on the inclined side of the trapezoidal block 5, the electromagnetic plate 501 is arranged obliquely, the horizontal height of the feeding end of the electromagnetic plate 501 is higher than the horizontal height of the discharging end, the magnetic roller 3 is located above the electromagnetic plate 501, a first recycling box 6 and a second recycling box 7 are fixedly mounted on the base 1, and the discharging end of the electromagnetic plate 501 faces the first recycling box 6;

[0034] Expansion member 10, the expansion member 10 is fixedly mounted on the base 1, the movable end of the expansion member 10 is fixedly mounted with a push plate 8, the push plate 8 is slidably matched with the electromagnetic plate 501. When the driving component drives the trapezoidal block 5 to move, so that the demagnetized area of the magnetic roller 3 faces the feeding end of the electromagnetic plate 501, the electromagnetic plate 501 is turned on. At this time, the discharging end of the electromagnetic plate 501 faces the first recycling box 6. When the driving component drives the trapezoidal block 5 to move, so that the electromagnetic plate 501 cooperates with the second recycling box 7, at this time the push plate 8 is aligned with the electromagnetic plate 501, and the expansion member 10 drives the push plate 8 to move to push the magnetic materials adsorbed on the electromagnetic plate 501 into the second recycling box 7;

[0035] When the driving component drives the trapezoidal block 5 to move, so that the electromagnetic plate 501 cooperates with the second recycling box 7, at this time the trapezoidal block 5 blocks the first recycling box 6;

[0036] The number of the electromagnetic plates 501 is two, and the two electromagnetic plates 501 are symmetrically arranged on the two inclined sides of the trapezoidal block 5. Each electromagnetic plate 501 has a corresponding first recycling box 6, a second recycling box 7 and an expansion member 10 arranged. When the driving component drives the trapezoidal block 5 to move, so that the demagnetized area of the magnetic roller 3 faces the feeding end of one electromagnetic plate 501, at this time the other electromagnetic plate 501 cooperates with the second recycling box 7.

[0037] In a case of this embodiment, it should be noted that the first conveyor belt 2, the second conveyor belt 4, the magnetic roller 3, and the electromagnetic plate 501 of the present invention are all prior arts, and the present invention has not improved them. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of the present invention; the driving source can be selected from components such as servo motors and servo motors, and other mechanisms capable of realizing rotational motion can also be selected. The driving component can be selected from components such as a threaded rod component driven by a motor and an electric cylinder, and other mechanisms capable of realizing linear reciprocating motion can also be selected. The expansion member 10 can be selected from components such as an electric cylinder and an electric telescopic rod, and other mechanisms capable of realizing linear reciprocating motion can also be selected. This embodiment does not make specific limitations here.

[0038] Working principle of the present invention: The components disassembled from new energy vehicles are subjected to pretreatment operations such as crushing and impurity removal. Subsequently, a vibrating screen is used to preliminarily screen the materials according to particle size. Then, the materials after vibrating screening are fed into a pneumatic separator, and pneumatic separation is carried out according to the characteristics of the materials such as density and shape. The separated mixed materials include magnetic materials and non-magnetic materials. Then, the mixed materials are evenly conveyed to the magnetic drum 3 through the first conveyor belt 2. Since the non-magnetic materials are not affected by the magnetic field, they are directly thrown out from the discharge end of the first conveyor belt 2 under the action of gravity and centrifugal force, and fall onto the second conveyor belt 4, and are conveyed by the second conveyor belt 4 to the non-magnetic material collection place. The magnetic materials among them are adsorbed by the magnetic field inside the magnetic drum 3 and adhere to the surface of the first conveyor belt 2 and rotate with it. When the magnetic materials rotate out of the magnetic field action range as the magnetic drum 3 rotates, that is, when the magnetic materials rotate to the lower part of the magnetic drum 3, the magnetic materials adsorbed on the magnetic drum 3 lose the magnetic force restraint and automatically fall off. At this time, the primary classification and recovery treatment are completed, separating most of the non-magnetic materials and magnetic materials. And a small amount of non-magnetic materials mixed in the magnetic materials will fall onto the electromagnetic plate 501 below the magnetic drum 3. At this time, the electromagnetic plate 501 is in the on state, adsorbing the magnetic materials on the electromagnetic plate 501, and a small amount of non-magnetic materials will slide along the inclined plate surface of the electromagnetic plate 501 and fall into the first recovery box 6. Subsequently, the driving assembly drives the trapezoidal block 5 to move on the bearing frame 103, enabling the electromagnetic plate 501 and the second recovery box 7 to cooperate. Then, the telescopic member 10 drives the push plate 8, and the push plate 8 pushes the magnetic materials adsorbed on the electromagnetic plate 501 into the second recovery box 7. In this way, the secondary classification and recovery treatment are completed, further ensuring the purity of the magnetic materials. In this process, the non-magnetic materials that were originally carried into the demagnetization area by the magnetic materials are completely removed, realizing the deep separation of magnetic materials and non-magnetic materials. In this way, through the secondary classification and recovery treatment, the complete separation of magnetic materials and non-magnetic materials is finally achieved. This not only improves the purity of the recycled materials, is conducive to the subsequent targeted recycling and reuse of different types of materials, improves the efficiency and value of resource recycling, but also greatly reduces the processing difficulty and cost brought by the mixing of materials with different properties, optimizing the classification and recovery process of the disassembled parts of new energy vehicles as a whole and improving the quality and efficiency of the entire recovery and treatment work;

[0039] And when the magnetic force generated by the electromagnetic plate 501 can attract the magnetic materials on the surface of the first conveyor belt 2, on the one hand, it assists the movement of the magnetic materials to the demagnetization area of the magnetic drum 3 for discharging, and on the other hand, it accelerates the falling of the magnetic materials, making the falling speeds of the magnetic materials and non-magnetic materials different. First, the magnetic materials are adsorbed onto the electromagnetic plate 501, and the non-magnetic materials will slide along the inclined plate surface of the electromagnetic plate 501 and fall into the first recovery box 6 for classification.

[0040] In practical application of this embodiment, as the push plate 8 pushes the magnetic materials adsorbed on the electromagnetic plate 501, the magnetic materials will pile up and squeeze each other. Then, the magnetic materials located at the edge of the discharge end of the electromagnetic plate 501 are easily squeezed and fall into the first recovery box 6. Therefore, when the driving component drives the trapezoidal block 5 to move so that the electromagnetic plate 501 cooperates with the second recovery box 7, at this time, the trapezoidal block 5 blocks the first recovery box 6. In this way, it can be ensured that when the push plate 8 pushes the magnetic materials on the electromagnetic plate 501, the materials will not fall into the first recovery box 6 and are all pushed into the second recovery box 7, ensuring the complete separation of magnetic materials and non-magnetic materials in automotive parts.

[0041] In practical application of this embodiment, through the design of two electromagnetic plates 501, when one electromagnetic plate 501 is below the demagnetization area of the magnetic force roller 3, it is performing the work of secondary classification. When the electromagnetic plate 501 is full of magnetic materials, a blanking operation is required. Therefore, the driving component drives the trapezoidal block 5 to move so that the electromagnetic plate 501 full of magnetic materials cooperates with the second recovery box 7 for blanking. At the same time, the other electromagnetic plate 501 moves to a position that cooperates with the demagnetization area of the magnetic force roller 3, and at this time, the work of secondary classification can continue. In this way, the purpose of continuous operation without stopping is achieved, thereby improving the efficiency of classifying new energy vehicle parts.

[0042] As Figures 1-3 shown, as a preferred embodiment of the present invention, a scraper 9 is fixedly installed on the first support 101. The scraper 9 is attached to the surface of the first conveyor belt 2, and the contact point between the two is located in the demagnetization area of the magnetic force roller 3.

[0043] In practical application of this embodiment, considering that the surface of the first conveyor belt 2 is elastic, when the magnetic force roller 3 adsorbs magnetic materials, non-magnetic materials may be squeezed by the magnetic materials and sink into the first conveyor belt 2, resulting in their inability to fall only by gravity in the demagnetization area of the magnetic force roller 3. Therefore, through the arrangement of the scraper 9, all the materials on the first conveyor belt 2 are scraped off to ensure that all blanking can be completed in the demagnetization area.

[0044] As Figures 1-6 shown, as a preferred embodiment of the present invention, a baffle extended platform 11 is fixedly installed on the first recovery box 6. When the trapezoidal block 5 blocks the first recovery box 6, the discharge end of the electromagnetic plate 501 faces the baffle extended platform 11. The push plate 8 is slidably matched with the baffle extended platform 11, and the telescopic member 10 drives the push plate 8 to push the magnetic materials on the electromagnetic plate 501 and the baffle extended platform 11 into the second recovery box 7.

[0045] In actual application of this embodiment, by setting the baffle extension platform 11, when the trapezoidal block 5 blocks the first recycling box 6, the discharge end of the electromagnetic plate 501 faces the baffle extension platform 11. Then, when the push plate 8 pushes the magnetic material adsorbed on the electromagnetic plate 501, the extrusion will cause the material to move to the baffle extension platform 11, thereby preventing the material from being squeezed out of the recycling area of ​​the second recycling box 7.

[0046] like Figures 1-6 As shown, as a preferred embodiment of the present invention, when the discharge end of the electromagnetic plate 501 is facing the extension platform 11 with the baffle, the electromagnetic plate 501 is closed.

[0047] In actual application of this embodiment, after the electromagnetic plate 501 is closed, under the action of gravity, the magnetic material adsorbed on the electromagnetic plate 501 will slide along the inclined plate surface of the electromagnetic plate 501, and then fall onto the extension platform 11 with the baffle. At this time, there is very little material remaining on the electromagnetic plate 501, especially near the feeding end of the electromagnetic plate 501. Then, when the push plate 8 is pushed, the magnetic material at the feeding end of the electromagnetic plate 501 can be prevented from being squeezed onto another electromagnetic plate 501.

[0048] like Figures 1-6 As shown, as a preferred embodiment of the present invention, a side baffle 12 is rotatably installed on the trapezoidal block 5, and the side baffle 12 is driven to rotate by the built-in output source of the trapezoidal block 5. There is a corresponding side baffle 12 on both sides of each electromagnetic plate 501. When the demagnetization area of ​​the magnetic roller 3 is toward the feeding end of the electromagnetic plate 501, the side baffle 12 corresponding to the electromagnetic plate 501 rotates, so that a feeding channel 14 is formed on the electromagnetic plate 501, and the width of the feeding channel 14 at the discharge end is smaller than the entrance width of the first recovery box 6; before the electromagnetic plate 501 slides with the push plate 8, the side baffle 12 rotates away from the electromagnetic plate 501.

[0049] In one case of this embodiment, the output source may be a servo motor, a servo motor or other components, or other mechanisms capable of achieving rotational motion, which is not specifically limited in this embodiment.

[0050] In practical application, if Figure 4 As shown in the figure, when the demagnetization zone of the magnetic roller 3 faces the feeding end of the electromagnetic plate 501, the side baffle 12 corresponding to the electromagnetic plate 501 rotates, so that a feeding channel 14 is formed on the electromagnetic plate 501. At this time, the material falling from the demagnetization zone of the magnetic roller 3 enters the feeding channel 14. Due to the obstruction of the side baffle 12, the material is prevented from falling from both sides of the electromagnetic plate 501, ensuring that the material can be screened and classified by the electromagnetic plate 501. After the classification is completed, before the electromagnetic plate 501 and the push plate 8 slide together, that is, the electromagnetic plate 501 needs to unload the material, the side baffle 12 rotates away from the electromagnetic plate 501. At this time, Figure 5As shown, the side baffle 12 will not block the pusher plate 8 from pushing the magnetic material on the electromagnetic plate 501.

[0051] As Figures 1-6 shown, as a preferred embodiment of the present invention, when the telescopic member 10 contracts, a gap 13 is formed between the pusher plate 8 and the trapezoidal block 5, and the gap 13 allows the side baffle 12 to rotate away from the electromagnetic plate 501.

[0052] In actual application of this embodiment, when the electromagnetic plate 501 cooperates with the demagnetization area of the magnetic drum 3, the telescopic member 10 is in a contracted state. When the electromagnetic plate 501 needs to discharge materials, the trapezoidal block 5 can directly drive the electromagnetic plate 501 to move to a position where it cooperates with the second recycling bin 7. At this time, another electromagnetic plate 501 can immediately perform the work of secondary classification. The existence of the gap 13 allows the output source to drive the side baffle 12 to rotate, so that the side baffle 12 rotates away from the electromagnetic plate 501. Then the telescopic member 10 extends to let the pusher plate 8 push the magnetic material on the electromagnetic plate 501, thus avoiding the problem that when the electromagnetic plate 501 is still below the demagnetization area, the side baffle 12 rotates away from the electromagnetic plate 501, resulting in the risk that materials may fall from both sides of the electromagnetic plate 501 still existing.

[0053] A detailed description of an embodiment of the present invention has been given above, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
