Description

Technical Field

[0001] The present invention relates to the technical field of recycling devices, and in particular to a battery shell recycling and sorting device. Background Art

[0002] Lead-acid battery is a storage battery whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. When the lead-acid battery is in the discharged state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. When the lead-acid battery is in the charged state, the main components of the positive and negative electrodes are both lead sulfate. Since the inner core of the lead-acid battery contains a large amount of recyclable metal materials, after the lead-acid battery is scrapped, the lead-acid battery shell needs to be opened, and the inner core needs to be removed to separate the battery shell from the inner core, and then the two can be recycled separately.

[0003] There are many types of lead-acid battery shells, which can be mainly classified by material. Common lead-acid battery shells can be divided into plastic and metal materials. When existing recycling devices recycle and crush lead-acid battery shells, in order to avoid mixing, usually one device can only crush and recycle battery shells of the same material, which has limitations.

[0018] Beneficial effects of the present invention:

[0019] 1. When in use, the battery shells to be recycled and crushed are transported to the screening induction component at the upper end of the crusher through the external belt feeder. The external belt feeder rotates intermittently, so that only one battery shell to be processed falls into the screening induction component at a time. At this time, the screening induction component determines whether the battery shell is made of plastic or metal, and then the guide component adjusts the angle. If the battery shell is made of plastic, the guide component rotates clockwise at a certain angle. When the battery shell is made of metal, the guide component rotates counterclockwise at a certain angle, so that the battery shells of different materials are respectively guided to the corresponding crushing rollers for processing. After the battery shells of different materials are crushed by the corresponding crushing rollers, they become fragments and fall through the corresponding bottom guide covers to the corresponding discharge belt conveyor. Then the discharge belt conveyor transports the fallen battery shell fragments away. In the process of crushing and recycling the battery shells, the equipment can crush and recycle battery shells of different materials at the same time without mixing.

[0020] 2. During use, when the crushed battery shells to be recycled are conveyed to the screening belt conveyor, the screening belt conveyor rotates, thereby driving the battery shell to move toward the feeding port. During this process, the battery shell will pass under the magnet plate, and the infrared photoelectric switch detects that an object has passed. When the battery shell is made of plastic, the magnet plate will not react when the battery shell passes under the magnet plate, and no displacement will occur, so that the sensing unit will not react. At this time, the guiding component rotates clockwise to cooperate with the guiding of the battery shell. When the battery shell is made of metal, the magnet plate will be displaced downward for a distance under the action of magnetic force when the battery shell passes under the magnet plate, so that the sensing unit detects the abnormality, thereby prompting the guiding component to rotate counterclockwise to cooperate with the guiding of the battery shell.

[0021] 3. In the initial state, the rotating roller on the arc-shaped clamping block is in contact with the surface of the connecting disk. When the middle material guide cover and the upper material guide cover rotate, the connecting shaft 2 and the connecting disk will also be driven to rotate together. During the rotation of the connecting disk, the arc-shaped groove will be driven to rotate together. When the arc-shaped groove is aligned with the corresponding arc-shaped clamping block, the arc-shaped clamping block is inserted into the arc-shaped groove under the action of the elastic member, thereby bringing the proximity switch 2 into the arc-shaped groove. At this time, the proximity switch 2 sends an electrical signal to control the servo motor to cut off the power. At this time, the arc-shaped clamping block clamps the connecting disk and the connecting shaft 2 through the arc-shaped groove, so that the middle material guide cover and the upper material guide cover maintain this state. The material guiding work of the battery shell is carried out together. In the initial state, the telescopic end of the cylinder is in an extended state. When the limit fixation of the connecting disk needs to be released, the telescopic end of the cylinder contracts quickly, thereby driving the movable plate, the telescopic rod and the arc-shaped clamping block away from the connecting disk, until the rotating roller on the inner surface of the arc-shaped clamping block is no longer in contact with the connecting disk, and then the middle material guiding cover and the upper material guiding cover return to the initial position under the action of gravity. At this time, the arc-shaped groove is vertically downward, and then the cylinder just now causes the telescopic end to extend again, causing the rotating roller on the inner surface of the arc-shaped clamping block to contact the surface of the connecting disk again. At this time, the spring 2 is compressed and deformed again to store elastic potential energy, ready for the next round of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Reference Figure 1-Figure 3 When in use, the battery shells to be recycled and crushed are transported to the screening induction component at the upper end of the crusher 1 through the external belt feeder. The external belt feeder rotates intermittently, so that only one battery shell to be processed falls into the screening induction component at a time. At this time, the screening induction component determines whether the battery shell is made of plastic or metal, and then the guide component adjusts the angle. If the battery shell is made of plastic, the guide component rotates clockwise by a certain angle. When the battery shell is made of metal, the guide component rotates counterclockwise by a certain angle, so that the battery shells of different materials are respectively guided to the corresponding crushing rollers 3 for processing. After the battery shells of different materials are crushed and processed by the corresponding crushing rollers 3, they become fragments and fall through the corresponding bottom guide covers 4 onto the corresponding discharge belt conveyor 5. Then the discharge belt conveyor 5 transports the fallen battery shell fragments away. In the process of crushing and recycling the battery shells, the equipment can crush and recycle battery shells of different materials at the same time without mixing.

[0033] Reference Figure 1 and Figure 4 The screening sensing component includes a screening belt conveyor 7 fixed to the upper end surface of the crusher 1. Two side panels 8 are symmetrically fixed to the upper end surface of the screening belt conveyor 7. The same mounting top plate 9 is fixed to one side of the upper end surfaces of the two side panels 8. A magnet plate 10 is movably arranged directly below the mounting top plate 9. A guide unit is arranged between the mounting top plate 9 and the magnet plate 10. An induction unit used in conjunction with the guiding component is arranged on the mounting top plate 9. An infrared photoelectric switch 30 is fixedly and penetrated between the two side panels 8. The infrared photoelectric switch 30 is a prior art.

[0034] Reference Figure 1 and Figure 4 When in use, when the crushed battery shells to be recycled are conveyed to the screening belt conveyor 7, the screening belt conveyor 7 rotates, thereby driving the battery shells to move toward the feeding port 6. During this process, the battery shells will pass under the magnet plate 10, and the infrared photoelectric switch 30 detects that an object has passed.

[0035] Reference Figure 1 , Figure 3 and Figure 4 When the battery shell is made of plastic, when the battery shell passes under the magnet plate 10, the magnet plate 10 does not react and does not move, so that the sensing unit does not react. At this time, the guiding component rotates clockwise to guide the battery shell. When the battery shell is made of metal, when the battery shell passes under the magnet plate 10, the magnet plate 10 will move downward for a distance under the action of magnetic force, so that the sensing unit detects the abnormality, thereby prompting the guiding component to rotate counterclockwise to guide the battery shell.

[0036] After each time the guiding component guides the battery shell, it returns to the initial position (in a vertical downward state).

[0037] Reference Figure 4 The guide unit includes two guide rods 11 fixed to the upper end surface of the magnet plate 10. The upper end of each guide rod 11 movably penetrates the mounting top plate 9. Two springs 1 are symmetrically fixed between the top of the mounting top plate 9 and the magnet plate 10. Each spring 1 is movably sleeved on the outer wall of the guide rod 11.

[0038] Reference Figure 4 The sensing unit includes a T-shaped plate 12 fixed to the upper end surface of the mounting top plate 9. Both ends of the upper end surface of the T-shaped plate 12 are provided with mounting through holes. A proximity switch 13 used in conjunction with the guide rod 11 is fixed in each mounting through hole. A control main board is provided on the crusher 1, and the control main board is the prior art.

[0039] Reference Figure 1 and Figure 4When the metal battery shell passes under the magnet plate 10, the magnet plate 10 will move downward for a distance under the action of magnetic force, thereby driving the guide rod 11 to move downward for a distance. At this time, the end of the guide rod 11 is away from the working end of the proximity switch 13, and the proximity switch 13 is disconnected, generating an electrical signal, thereby causing the guide component to rotate counterclockwise with the cooperation of the control main board.

[0040] Reference Figure 1 and Figure 4 When the magnet plate 10 moves downward, the spring 1 is stretched and deformed to store elastic potential energy. When the metal battery shell falls into the feeding port 6 under the transportation of the screening belt conveyor 7, the spring 1 prompts the magnet plate 10 to move upward and return to the initial state. In the initial state, the guide rod 11 contacts the working end of the proximity switch 13, and the proximity switch 13 is in a normal state.

[0041] Reference Figure 2 , Figure 3 and Figure 5 The guiding assembly includes an intermediate material guiding cover 14 rotatably arranged on the inner wall of the crusher 1, an upper material guiding cover 15 is connected to the upper end of the intermediate material guiding cover 14, a connecting shaft 16 and a connecting shaft 2 17 are respectively fixed on both sides of the intermediate material guiding cover 14, the connecting shaft 1 16 and the connecting shaft 2 17 both rotate and penetrate the side wall of the crusher 1, a driving unit 1 used in conjunction with the connecting shaft 16 is arranged on the outer wall of the crusher 1, and a limiting unit used in conjunction with the connecting shaft 2 17 is arranged on the outer wall of the crusher 1.

[0044] Reference Figure 5 When the servo motor 31 is working, the driving shaft drives the small gear ring 21 to rotate, and the small gear ring 21 drives the large gear ring 19 and the connecting shaft 16 to rotate, thereby driving the middle material guide cover 14 and the upper material guide cover 15 to rotate, and cooperate to guide the battery shell.

[0045] Reference Figure 2 , Figure 6 and Figure 7The limiting unit includes a connecting disk 22 fixedly sleeved on the outer surface of the connecting shaft 17, and an arc-shaped groove 23 is provided on the outer surface of the connecting disk 22. Two movable plates 33 are symmetrically and obliquely arranged on the side wall of the crusher 1, and an arc-shaped block 24 is arranged above each movable plate 33. A plurality of rotating rollers 25 are rotatably arranged on the upper surface of the arc-shaped block 24, and an elastic member is arranged between the arc-shaped block 24 and the movable plate 33. Two driving units 2 used in conjunction with the corresponding movable plates 33 are symmetrically arranged on the side wall of the crusher 1, and a side groove is provided on the side wall of each arc-shaped block 24, and a proximity switch 2 32 is fixed in each side groove.

[0046] Reference Figure 2 , Figure 6 and Figure 7 In the initial state, the rotating roller 25 on the arc-shaped clamping block 24 is in contact with the surface of the connecting disk 22. When the intermediate material guide cover 14 and the upper material guide cover 15 rotate, the connecting shaft 2 17 and the connecting disk 22 will also be driven to rotate together. During the rotation of the connecting disk 22, the arc-shaped groove 23 will be driven to rotate together. When the arc-shaped groove 23 is aligned with the corresponding arc-shaped clamping block 24, the arc-shaped clamping block 24 is inserted into the arc-shaped groove 23 under the action of the elastic member, thereby entering the arc-shaped groove 23 with the proximity switch 2 32. At this time, the proximity switch 2 32 sends an electrical signal to control the servo motor 31 to cut off power. At this time, the arc-shaped clamping block 24 clamps the connecting disk 22 and the connecting shaft 2 17 through the arc-shaped groove 23, so that the intermediate material guide cover 14 and the upper material guide cover 15 maintain this state and cooperate in the material guiding work of the battery shell.

[0047] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 When the middle material guide cover 14 and the upper material guide cover 15 rotate to a certain angle and cooperate to complete the guiding work of the battery shell, the driving unit 2 drives the arc-shaped clamping block 24 to quickly move away from the connecting disk 22, releasing the limit fixation on the connecting disk 22, so that the middle material guide cover 14 and the upper material guide cover 15 are restored to the initial state of vertical downward under the action of gravity.

[0048] Reference Figure 7 Each elastic member includes a telescopic rod 26 fixed between the arc-shaped block 24 and the movable plate 33 and a second spring, and the second spring is movably sleeved on the outer surface of the telescopic rod 26.

[0049] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7In the initial state, the rotating roller 25 on the arc-shaped clamping block 24 is in contact with the surface of the connecting disk 22. At this time, the telescopic rod 26 is in a contracted state, and the spring 2 is in a compressed state, storing a certain elastic potential energy. When the connecting disk 22 rotates with the arc-shaped groove 23 to align with the corresponding arc-shaped clamping block 24, the arc-shaped clamping block 24 is quickly inserted into the arc-shaped groove 23 under the action of the elastic potential energy of the spring 2, thereby limiting the connecting disk 22.

[0050] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 Each driving unit 2 includes a fixed seat 27 fixed on the side wall of the crusher 1, and a cylinder 28 is fixed between the fixed seat 27 and the movable plate 33. Each fixed seat 27 is symmetrically and movably penetrated by two guide columns 29 on one side close to the corresponding movable plate 33. The upper end of each guide column 29 movably penetrates the movable plate 33 and is fixedly connected to the lower surface of the arc-shaped block 24.

[0051] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 In the initial state, the telescopic end of the cylinder 28 is in an extended state. When the limit fixation of the connecting disk 22 needs to be released, the telescopic end of the cylinder 28 contracts rapidly, thereby driving the movable plate 33, the telescopic rod 26 and the arc-shaped block 24 away from the connecting disk 22 until the rotating roller 25 on the inner surface of the arc-shaped block 24 is no longer in contact with the connecting disk 22, and then the middle material guide cover 14 and the upper material guide cover 15 return to the initial position under the action of gravity. At this time, the arc-shaped groove 23 is vertically downward, and then the cylinder 28 just now causes the telescopic end to extend again, causing the rotating roller 25 on the inner surface of the arc-shaped block 24 to contact the surface of the connecting disk 22 again. At this time, the spring 2 is compressed and deformed again, storing elastic potential energy, and preparing for the next round of use.

[0052] When the present invention is used, refer to Figure 1-Figure 3, the battery shells to be recycled and crushed are transported toward the screening induction component at the upper end of the crusher 1 through an external belt feeder, and the external belt feeder rotates intermittently, so that only one battery shell to be processed falls into the screening induction component at a time. At this time, the screening induction component determines whether the battery shell is made of plastic or metal, and then the guide component adjusts the angle. If the battery shell is made of plastic, the guide component rotates clockwise at a certain angle, and when the battery shell is made of metal, the guide component rotates counterclockwise at a certain angle, so that the battery shells of different materials are respectively guided to the corresponding crushing rollers 3 for processing. After the battery shells of different materials are crushed and processed by the corresponding crushing rollers 3, they become fragments and fall through the corresponding bottom guide covers 4 onto the corresponding discharging belt conveyor 5, and then the discharging belt conveyor 5 transports the fallen battery shell fragments away. In the process of crushing and recycling the battery shells, the equipment can crush and recycle battery shells of different materials at the same time without mixing.

[0053] Reference Figure 1 , Figure 3 and Figure 4 When in use, when the crushed battery shells to be recycled are conveyed to the screening belt conveyor 7, the screening belt conveyor 7 rotates, thereby driving the battery shell to move toward the feeding port 6. During this process, the battery shell will pass under the magnet plate 10, and the infrared photoelectric switch 30 detects that an object has passed. When the battery shell is made of plastic, when the battery shell passes under the magnet plate 10, the magnet plate 10 does not react and does not move, so that the sensing unit does not react. At this time, the guiding component rotates clockwise to cooperate with the guiding of the battery shell. When the battery shell is made of metal, when the battery shell passes under the magnet plate 10, the magnet plate 10 will move downward for a distance under the action of magnetic force, so that the sensing unit detects an abnormality, thereby prompting the guiding component to rotate counterclockwise to cooperate with the guiding of the battery shell.

[0054] Reference Figure 2 , Figure 6 and Figure 7 In the initial state, the rotating roller 25 on the arc-shaped clamping block 24 is in contact with the surface of the connecting disk 22. When the intermediate material guide cover 14 and the upper material guide cover 15 rotate, the connecting shaft 2 17 and the connecting disk 22 will also be driven to rotate together. During the rotation of the connecting disk 22, the arc-shaped groove 23 will be driven to rotate together. When the arc-shaped groove 23 is aligned with the corresponding arc-shaped clamping block 24, the arc-shaped clamping block 24 is inserted into the arc-shaped groove 23 under the action of the elastic member, thereby entering the arc-shaped groove 23 with the proximity switch 2 32. At this time, the proximity switch 2 32 sends an electrical signal to control the servo motor 31 to cut off power. At this time, the arc-shaped clamping block 24 clamps the connecting disk 22 and the connecting shaft 2 17 through the arc-shaped groove 23, so that the intermediate material guide cover 14 and the upper material guide cover 15 maintain this state and cooperate in the material guiding work of the battery shell;

[0055] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 In the initial state, the telescopic end of the cylinder 28 is in an extended state. When the limit fixation of the connecting disk 22 needs to be released, the telescopic end of the cylinder 28 contracts rapidly, thereby driving the movable plate 33, the telescopic rod 26 and the arc-shaped block 24 away from the connecting disk 22 until the rotating roller 25 on the inner surface of the arc-shaped block 24 is no longer in contact with the connecting disk 22, and then the middle material guide cover 14 and the upper material guide cover 15 return to the initial position under the action of gravity. At this time, the arc-shaped groove 23 is vertically downward, and then the cylinder 28 just now causes the telescopic end to extend again, causing the rotating roller 25 on the inner surface of the arc-shaped block 24 to contact the surface of the connecting disk 22 again. At this time, the spring 2 is compressed and deformed again, storing elastic potential energy, and preparing for the next round of use.
