Description

Technical Field

[0001] This application relates to the field of battery processing equipment technology, and in particular to a demagnetization and recycling device and a battery production line. Background Technology

[0002] In the battery production process, a mixing tank is usually used to supply materials (such as slurry) to the battery production equipment. Before entering the production equipment, the materials usually pass through equipment such as high-efficiency iron removers and filtration structures (such as filter elements and steel shells for installing filter elements). However, during the transportation process, some materials with magnetic particles or other impurities will adhere to the iron removal rods of the high-efficiency iron remover and the filtration structure, resulting in the scrapping of this part of the material. Utility Model Content

[0003] In view of the above problems, this application provides a demagnetization and recycling device and a battery production line, aiming to provide a demagnetization and recycling device that can realize offline recycling of materials.

[0004] This application provides a demagnetization and recovery device, including a storage tank and a circulation pipeline; the storage tank is configured to store the recovered material and has a discharge port and a feed port; the circulation pipeline has a feed end and a discharge end, the feed end being connected to the discharge port and the discharge end being connected to the feed port; wherein, the circulation pipeline is equipped with a pump body, a filter, and a demagnetizer; the pump body is configured to provide power for the material flow between the storage tank and the circulation pipeline; the filter is configured to filter out large particulate impurities in the material flowing through the filter; the demagnetizer is configured to adsorb magnetic particles in the material flowing through the demagnetizer.

[0005] In the technical solution of this application embodiment, this solution provides a demagnetizing recycling device capable of offline recycling of materials. After the battery production line has been operating for a period of time, the materials attached to the iron removal rods, filter structures, and other equipment of the high-efficiency iron remover in the battery production line can be transferred manually or mechanically to the storage tank of the demagnetizing recycling device. Then, under the action of the pump, the materials in the storage tank can flow to the circulation pipeline. Then, they flow through the filter and demagnetizer in the circulation pipeline. The filter removes impurities from the materials, and the demagnetizer adsorbs magnetic particles from the materials. Then, the materials flow back to the storage tank. Under the continuous circulation of the materials, the materials are cleaned of impurities and demagnetized. The recycled materials are demagnetized and then transferred back to the mixing tank on the battery production line for recycling. Therefore, the demagnetizing recycling device provided by this solution can realize offline recycling of materials to reduce material waste.

[0006] In some embodiments, the demagnetizer includes at least two demagnetizing components connected in series in the circulation pipeline. This design, by employing at least two series-connected demagnetizing components to sequentially adsorb magnetic particles in the material, enables multi-stage adsorption of magnetic particles in the material, thereby improving the demagnetization effect and reducing the number of demagnetization cycles, thus improving the working efficiency of the demagnetization and recovery equipment.

[0007] In some embodiments, the demagnetizing component includes a mounting sleeve and a magnetic rod; the interior of the mounting sleeve is connected to a circulation pipeline; the magnetic rod is inserted into the mounting sleeve and configured to adsorb magnetic particles in the material flowing through the interior of the mounting sleeve. This design, by employing the mounting sleeve and magnetic rod, increases the contact area between the magnetic rod and the material, allowing the surface of the magnetic rod to effectively adsorb magnetic particles in the material flowing through the mounting sleeve, thereby further improving the demagnetizing effect on the material.

[0008] In some embodiments, the filter includes a housing and a filter element; the interior of the housing is in communication with a circulation pipeline; the filter element is disposed within the housing and configured to filter out impurities from the material flowing through it. This design, by employing a housing and filter element configuration, allows material to flow smoothly through the filter element after entering the housing, thereby improving the filtration efficiency.

[0009] In some embodiments, the housing has a first inlet and a first outlet, and the filter element has a second inlet and a second outlet. The first inlet is connected to the circulation pipeline and is located near the bottom of the housing; the second inlet is connected to the first inlet and is located near the top of the housing; the second outlet is connected to the second inlet and is located near the bottom of the housing; the first outlet is connected to the second outlet and the circulation pipeline and is located near the bottom of the housing. With this design, material flowing through the circulation pipeline can enter the housing from the first inlet, flow upwards towards the second inlet of the filter element, and then flow downwards through the filter element, allowing for more thorough flow and further improving the filtration effect. The material flowing through the filter element flows from the second outlet of the filter element to the first outlet of the housing, and finally from the first outlet of the housing back into the circulation pipeline.

[0010] In some embodiments, the demagnetization and recovery equipment also includes a discharge pipe connected to a circulation pipeline. With this design, the demagnetized material can be stored in a storage tank. When the material in the storage tank needs to be used, it can be pumped to the circulation pipeline and then flow from the circulation pipeline to the discharge pipe for automatic material discharge.

[0011] In some embodiments, the discharge pipe is located upstream of the demagnetizer. With this design, when the material in the storage tank needs to be used, the material in the storage tank can be transported to the circulation pipeline by the pump, and then flow from the circulation pipeline to the discharge pipe. At this time, the material no longer flows to the demagnetizer, so as to achieve the effect of rapid discharge.

[0012] In some embodiments, a first valve body is provided on the discharge pipe, and a second valve body is provided on the circulation pipe, the second valve body being located between the discharge pipe and the demagnetizer. With this design, when the demagnetizing and recovery equipment is used for cyclic demagnetization, the first valve body is closed and the second valve body is opened, allowing the material flowing through the circulation loop to flow to the demagnetizer for demagnetization treatment; when the demagnetizing and recovery equipment is used for discharge, the first valve body is opened and the second valve body is closed, allowing the material flowing through the circulation loop to exit from the discharge pipe. Therefore, the design of the first and second valve bodies enables precise switching between demagnetization and discharge operations.

[0013] In some embodiments, the filter is located at the connection between the discharge pipe and the circulation pipe. This design not only allows the material to pass through the filter to remove impurities before entering the demagnetizer, but also allows the material to pass through the filter again to remove impurities before exiting from the discharge pipe, thereby further improving the impurity removal effect on the material.

[0014] In some embodiments, the demagnetizing and recycling equipment also includes a transfer trolley, on which the storage tank, circulation pipeline, pump body, filter, and demagnetizer are all mounted. This design allows the demagnetizing and recycling equipment to be moved to different locations via the transfer trolley, facilitating material transfer. For example, when the recycled material needs to be poured into the storage tank, the transfer trolley can move the demagnetizing and recycling equipment to the vicinity of the high-efficiency iron separator on the battery production line, allowing the user to pour the material recovered from the high-efficiency iron separator into the storage tank; alternatively, the transfer trolley can move the demagnetizing and recycling equipment to the vicinity of the filter structure on the battery production line, allowing the user to pour the material recovered from the filter structure into the storage tank; after material collection, the transfer trolley can move the demagnetizing and recycling equipment to a designated location for circulating demagnetization; after demagnetization, the transfer trolley can also move the demagnetizing and recycling equipment to the vicinity of the mixing tank on the battery production line, allowing the user to transfer the processed material into the mixing tank.

[0015] In some embodiments, a first identification chip is provided inside the storage tank, and the first identification chip is configured to mutually identify with a fourth identification chip in the material recycler. This design, by placing the first identification chip inside the storage tank, ensures that before the recycled material is poured into the storage tank through the material recycler, the first identification chip in the storage tank and the fourth identification chip in the material recycler are matched and identified correctly. Only when the first identification chip and the fourth identification chip are correctly matched can the material collected in the material recycler be poured into the storage tank, thereby preventing material mixing.

[0016] This application also provides a battery production line, including a mixing tank, a feeding pipeline, battery production equipment, the aforementioned demagnetizing and recycling equipment, and a material collector; a second identification chip is provided inside the mixing tank; the inlet of the feeding pipeline is connected to the outlet of the mixing tank; the feeding pipeline is configured to supply materials to the battery production equipment; the feeding pipeline is equipped with a high-efficiency iron remover and a filter structure, the high-efficiency iron remover is configured to adsorb magnetic particles in the material flowing through the high-efficiency iron remover, and the filter structure is configured to filter out impurities in the material flowing through the filter structure; a third identification chip is provided inside the high-efficiency iron remover and the filter structure; a first identification chip is provided inside the storage tank of the demagnetizing and recycling equipment; a fourth identification chip is provided inside the material collector, the material collector is configured to collect the material attached to the high-efficiency iron remover and the filter structure, and transfer the recovered material to the storage tank; the material collector is also configured to collect the demagnetized material from the demagnetizing and recycling equipment, and transfer the material to the mixing tank; wherein the first identification chip, the second identification chip, and the third identification chip all mutually identify with the fourth identification chip. This design enables automatic identification of material recycling, transfer, demagnetization, and mixing processes through mutual recognition between the first, second, and third identification chips and the fourth identification chip, thereby achieving anti-mixing recycling of different products.

[0037] In the battery production process, a mixing tank is usually used to supply materials (such as slurry) to the battery production equipment. Before entering the production equipment, the materials usually pass through equipment such as high-efficiency iron removers and filtration structures (such as filter elements and steel shells for installing filter elements). However, during the transportation process, some materials with magnetic particles or other impurities will adhere to the iron removal rods of the high-efficiency iron remover and the filtration structure, resulting in the scrapping of this part of the material.

[0038] Based on the above problems, this application proposes a demagnetization and recycling device 100, aiming to provide a demagnetization and recycling device 100 capable of realizing offline recycling of materials. The following detailed description is provided in conjunction with specific accompanying drawings and embodiments.

[0039] Please see Figures 1-3 In one embodiment of this application, the demagnetizing and recycling equipment 100 includes a storage tank 10 and a circulation pipeline 20; the storage tank 10 is configured to store recycled materials and has an outlet 12 and an inlet 11; the circulation pipeline 20 has an inlet end 21 and an outlet end 22, the inlet end 21 is connected to the outlet 12, and the outlet end 22 is connected to the inlet 11; wherein, the circulation pipeline 20 is provided with a pump body 30, a filter 40, and a demagnetizer 50; the pump body 30 is configured to provide power for material flow between the storage tank 10 and the circulation pipeline 20; the filter 40 is configured to filter out large particulate impurities in the material flowing through the filter 40; the demagnetizer 50 is configured to adsorb magnetic particles in the material flowing through the demagnetizer 50.

[0040] The storage tank 10 is a container for collecting and storing recycled materials, which may be materials attached to structures such as the high-efficiency iron separator 500 and the filter structure 600 on the battery production line 1000. The top of the storage tank 10 is provided with a discharge port to facilitate the user's easy addition of recycled materials into the storage tank 10. Furthermore, to prevent external impurities from entering the storage tank 10 through the discharge port and contaminating the materials, a cover can be provided at the discharge port for opening or closing. In some embodiments, after the recycled materials are transferred to the storage tank 10 of the demagnetizing and recycling equipment 100, a GNS solution (glucose sodium chloride solution) can be added to the storage tank 10 to dilute the materials. The ratio of materials to GNS solution is 3:1, which facilitates material flow.

[0041] The discharge port 12 on the storage tank 10 is used to supply material to the circulation pipeline 20. The inlet 11 can be set at the bottom, side, top, or other positions of the storage tank 10, as long as the material in the storage tank 10 can flow smoothly to the circulation pipeline 20. The inlet 11 on the storage tank 10 is used to return the material in the circulation pipeline 20 to the storage tank 10. The discharge port 12 can also be set at the bottom, side wall, top, or other positions of the storage tank 10, as long as the material in the circulation pipeline 20 can flow smoothly back to the storage tank 10.

[0042] The circulation pipeline 20 forms a circulation loop with the storage tank 10, allowing the material flowing out of the storage tank 10 to pass through the circulation pipeline 20, and then through the pump body 30, filter 40, demagnetizer 50, and other structures on the circulation pipeline 20 before returning to the storage tank 10 through the circulation pipeline 20. The circulation pipeline 20 can be made of materials such as stainless steel, aluminum, or copper. The inlet 21 of the circulation pipe 20 can be directly inserted into the outlet 12 of the storage tank 10, or a pipe connector can be used to connect the inlet 21 of the circulation pipe 20 to the outlet 12 of the storage tank 10 to achieve communication between the inlet 21 of the circulation pipe 20 and the outlet 12 of the storage tank 10; the outlet 22 of the circulation pipe 20 can be directly inserted into the inlet 11 of the storage tank 10, or a pipe connector can be used to connect the outlet 22 of the circulation pipe 20 to the inlet 11 of the storage tank 10 to achieve communication between the outlet 22 of the circulation pipe 20 and the inlet 11 of the storage tank 10.

[0043] The pump body 30 is installed on the circulation pipeline 20 to provide power for material flow between the storage tank 10 and the circulation pipeline 20, so that the material in the storage tank 10 can flow smoothly into the circulation pipeline 20, and the material in the circulation pipeline 20 can flow smoothly back into the storage tank 10. The pump body 30 can be a pneumatic pump or a screw pump, etc.

[0044] Filter 40 is installed on the circulation pipeline 20 to remove impurities (such as large particles like sand and mud) from the material flowing through it. Filter 40 can be installed upstream or downstream of demagnetizer 50. Alternatively, to minimize the impact of impurities on demagnetizer 50, filter 40 can be installed upstream, allowing the material flowing through circulation pipeline 20 to pass through filter 40 before passing through demagnetizer 50. This allows impurities to be removed first by filter 40, and then magnetic particles to be adsorbed by demagnetizer 50.

[0045] The demagnetizer 50 is installed on the circulation pipeline 20 to adsorb magnetic particles in the material flowing through it. The demagnetizer 50 can use structures such as magnetic rods 512, magnetic sheets, and magnetic mesh to adsorb magnetic particles in the material.

[0046] In summary, the technical solution of this application provides a demagnetizing and recycling device 100 capable of offline recycling of materials. After the battery production line 1000 has been operating for a period of time, the materials attached to the iron removal rods 520 and filter structure 600 of the high-efficiency iron remover 500 in the battery production line 1000 can be transferred manually or mechanically to the storage tank 10 of the demagnetizing and recycling device 100. Then, under the action of the pump body 30, the materials in the storage tank 10 can flow to the circulation pipeline 20. Then, they flow through the filter 40 and demagnetizer 50 on the circulation pipeline 20. The filter 40 removes impurities from the materials, and the demagnetizer 50 adsorbs magnetic particles from the materials. The materials then flow back to the storage tank 10. Under the continuous circulation of the materials, the materials are cleaned of impurities and demagnetized. After the recycled materials are demagnetized, they are transferred back to the mixing tank 200 on the battery production line 1000 for recycling. Therefore, the demagnetizing and recycling device 100 provided by this solution can realize offline recycling of materials to reduce the scrapping of materials.

[0047] Please see Figure 3 In one embodiment of this application, the demagnetizer 50 includes at least two demagnetizing components 51 connected in series on the circulation pipeline 20.

[0048] Each demagnetizing element 51 is capable of individually adsorbing magnetic particles in the material flowing through it. Adjacent demagnetizing elements 51 can be connected by a connecting pipe 52. The first demagnetizing element 51 is connected to the upper half of the circulation pipe 20, and the last demagnetizing element 51 is connected to the lower half of the circulation pipe 20. After the material flows from the storage tank 10 to the upper half of the circulation pipe 20, it passes through the first demagnetizing element 51 for demagnetization, then flows through the connecting pipe 52 to the next demagnetizing element 51 for further demagnetization, and finally through the connecting pipe 52 to the last demagnetizing element 51 for further demagnetization. The number of demagnetizing elements 51 connected in series can be two, three, four, five, six, etc., and is not specifically limited here.

[0049] This design, by employing at least two series-connected demagnetizing elements 51 to sequentially adsorb magnetic particles in the material, enables multi-stage adsorption of magnetic particles in the material, thereby improving the demagnetization effect of the material and reducing the number of times the material is demagnetized, thus improving the working efficiency of the demagnetization and recycling equipment 100.

[0050] Please see Figure 3 In one embodiment of this application, the demagnetizing component 51 includes a mounting sleeve 511 and a magnetic rod 512; the interior of the mounting sleeve 511 is connected to the circulation pipeline 20; the magnetic rod 512 is inserted into the mounting sleeve 511 and is configured to adsorb magnetic particles in the material flowing through the interior of the mounting sleeve 511.

[0051] The mounting sleeve 511 is used to install on the circulation pipeline 20. Its interior is connected to the circulation pipeline 20, and a magnetic rod 512 is inserted inside the mounting sleeve 511. The material flowing through the circulation pipeline 20 enters the interior of the mounting sleeve 511 so that the magnetic rod 512 inside the mounting sleeve 511 can adsorb the magnetic particles in the material flowing through the mounting sleeve 511.

[0052] A magnetic rod 512 is inserted into the mounting sleeve 511. The magnetic field strength of the magnetic rod 512 is >12000gs, which can effectively attract magnetic particles in the material to its surface. The magnetic rod 512 can be fully inserted into the mounting sleeve 511; alternatively, it can be partially inserted into the mounting sleeve 511 with some parts extending out, making it easier to remove the magnetic rod 512 from the mounting sleeve 511 for periodic cleaning. Furthermore, to remove multiple magnetic rods 512 at once, they can be connected to a connecting rod. This allows multiple magnetic rods 512 to be removed from multiple mounting sleeves 511 simultaneously by simply removing the connecting rod, or multiple magnetic rods 512 to be inserted into multiple mounting sleeves 511 simultaneously.

[0053] This design, by using the mounting sleeve 511 and the magnetic rod 512, can increase the contact area between the magnetic rod 512 and the material, so that the surface of the magnetic rod 512 can effectively adsorb the magnetic particles in the material flowing through the mounting sleeve 511, thereby further improving the demagnetization effect on the material.

[0054] Please see Figure 4 In one embodiment of this application, the filter 40 includes a housing 41 and a filter element 42; the interior of the housing 41 is in communication with the circulation pipeline 20; the filter element 42 is disposed inside the housing 41 and is configured to filter out impurities in the material flowing through the filter element 42.

[0055] The housing 41 is used to be installed on the circulation pipeline 20. Its interior is connected to the circulation pipeline 20, and a filter element 42 is installed inside the housing 41. The material flowing through the circulation pipeline 20 enters the interior of the housing 41 so as to filter out impurities in the material through the filter element 42 inside the housing 41.

[0056] The filter element 42 is installed inside the housing 41. The filter element 42 may include one or at least two filter screens so that the material entering the housing 41 flows through the filter screens of the filter element 42 to isolate impurities in the material.

[0057] This design, by using the outer shell 41 and the filter element 42, allows the material to flow smoothly through the filter element 42 after entering the outer shell 41, thereby improving the filtration effect of the material.

[0058] Please see Figure 4In one embodiment of this application, the outer casing 41 is provided with a first inlet 411 and a first outlet 412, and the filter element 42 is provided with a second inlet 421 and a second outlet 422; the first inlet 411 is connected to the circulation pipeline 20 and is disposed near the bottom of the outer casing 41; the second inlet 421 is connected to the first inlet 411 and is disposed near the top of the outer casing 41; the second outlet 422 is connected to the second inlet 421 and is disposed near the bottom of the outer casing 41; the first outlet 412 is connected to the second outlet 422 and the circulation pipeline 20 and is disposed near the bottom of the outer casing 41.

[0059] With this design, the material flowing through the circulation pipe 20 can enter the outer shell 41 from the first inlet 411. The material entering the outer shell 41 flows from bottom to top to the second inlet 421 of the filter element 42. The material entering the filter element 42 flows from top to bottom through the filter element 42, allowing the material to flow through the filter element 42 more fully, thereby further improving the filtration effect of the filter element 42. The material flowing through the filter element 42 flows from the second outlet 422 of the filter element 42 to the first outlet 412 of the outer shell 41, and finally flows from the first outlet 412 of the outer shell 41 back into the circulation pipe 20.

[0060] Please see Figure 2 , Figure 3 In one embodiment of this application, the demagnetization and recycling device 100 further includes a discharge pipe 60, which is connected to the circulation pipeline 20.

[0061] The discharge pipe 60 is connected to the circulation pipe 20, allowing material flowing through the circulation pipe 20 to exit through the discharge pipe 60. The discharge pipe 60 has a receiving port, from which the user can use a material collector 700 to receive the material and then transfer it to the mixing tank 200 of the battery production line 1000 for use. Alternatively, the receiving port of the discharge pipe 60 can be directly connected to the mixing tank 200 of the battery production line 1000, allowing material to be directly transferred to the mixing tank 200 of the battery production line 1000 for use. The discharge pipe 60 can be made of materials such as stainless steel, aluminum, or copper.

[0062] With this design, the demagnetized material can be stored in a storage tank. When the material in the storage tank is needed, it can be transported to the circulation pipeline 20 by the pump body 30, and then flow from the circulation pipeline 20 to the discharge pipe 60 to achieve automatic material discharge.

[0063] Please see Figure 3 In one embodiment of this application, the discharge pipe 60 is located upstream of the demagnetizer 50.

[0064] With this design, when the material in the storage tank needs to be used, the pump body 30 can transport the material in the storage tank to the circulation pipeline 20, and then the material flows from the circulation pipeline 20 to the discharge pipe 60. At this time, the material no longer flows to the demagnetizer 50, so as to achieve the effect of rapid discharge.

[0065] Please see Figure 3 In one embodiment of this application, a first valve body 71 is provided on the discharge pipe 60, and a second valve body 72 is provided on the circulation pipe 20. The second valve body 72 is located between the discharge pipe 60 and the demagnetizer 50.

[0066] The first valve body 71 is installed on the discharge pipe 60 and is used to control the opening and closing of the discharge pipe 60. When the first valve body 71 is in the closed state, the material in the circulation pipe 20 cannot be discharged through the discharge pipe 60; when the first valve body 71 is in the open state, the material in the circulation pipe 20 can be discharged through the discharge pipe 60. The first valve body 71 can be an automatic valve or a manual valve. The second valve body 72 is installed on the circulation pipe 20 and located between the discharge pipe 60 and the demagnetizer 50, and is used to control the opening and closing of the pipeline between the discharge pipe 60 and the demagnetizer 50. When the second valve body 72 is in the closed state, the material in the circulation pipe 20 cannot flow to the demagnetizer 50; when the second valve body 72 is in the open state, the material in the circulation pipe 20 can flow to the demagnetizer 50. The second valve body 72 can be an automatic valve or a manual valve. In some embodiments, the demagnetization and recovery device 100 may further include a control system cabinet 90, which is used to communicate with the pump body 30, the first valve body 71 and the second valve body 72, and is able to control the opening and closing and power of the pump body 30, as well as the opening and closing and opening degree of the first valve body 71 and the second valve body 72.

[0067] With this design, when the demagnetizing and recycling device 100 is used for cyclic demagnetization, the first valve body 71 is closed and the second valve body 72 is opened, allowing the material flowing through the circulation loop to flow to the demagnetizer 50 for demagnetization treatment. When the demagnetizing and recycling device 100 is used for discharging, the first valve body 71 is opened and the second valve body 72 is closed, allowing the material flowing through the circulation loop to be discharged from the discharge pipe 60. Therefore, the design of the first valve body 71 and the second valve body 72 enables precise switching between demagnetization and discharging operations.

[0068] Please see Figure 3 In one embodiment of this application, the filter 40 is disposed at the connection between the discharge pipe 60 and the circulation pipe 20.

[0069] This design not only allows the material to pass through filter 40 to remove impurities before entering demagnetizer 50, but also allows the material to pass through filter 40 again to remove impurities before exiting from discharge pipe 60, which can further improve the impurity removal effect on the material.

[0070] Please see Figures 1-2 In one embodiment of this application, the demagnetizing and recycling equipment 100 further includes a transfer trolley 80, and the storage tank 10, circulation pipeline 20, pump body 30, filter 40 and demagnetizer 50 are all disposed on the transfer trolley 80.

[0071] The transfer trolley 80 can transfer the upper structure installed on the transfer trolley 80 to different positions. The transfer trolley 80 may include an installation platform and casters set at the bottom of the installation platform. The installation platform is used to install and carry the storage tank 10, circulation pipeline 20, pump body 30, filter 40 and demagnetizer 50.

[0072] This design allows the demagnetizing and recycling equipment 100 to be moved to different locations via a transfer trolley 80, facilitating material transfer. For example, when the recycled material needs to be added to the storage tank 10, the demagnetizing and recycling equipment 100 can be moved by the transfer trolley 80 to the vicinity of the high-efficiency iron separator 500 in the battery production line 1000, so that the user can add the material recycled from the high-efficiency iron separator 500 to the storage tank 10; alternatively, the demagnetizing and recycling equipment 100 can be moved by the transfer trolley 80 to the vicinity of the filter structure 600 in the battery production line 1000, so that the user can add the material recycled from the filter structure 600 to the storage tank 10; after material collection, the demagnetizing and recycling equipment 100 can be moved by the transfer trolley 80 to a designated location for cyclic demagnetization; after demagnetization, the demagnetizing and recycling equipment 100 can also be moved by the transfer trolley 80 to the vicinity of the mixing tank 200 in the battery production line 1000, so that the user can transfer the processed material to the mixing tank 200.

[0073] Please see Figure 3 , Figure 7 In one embodiment of this application, a first identification chip 13 is provided in the storage tank 10, and the first identification chip 13 is configured to mutually identify with the fourth identification chip 710 in the material recycling unit 700.

[0074] Both the first identification chip 13 and the fourth identification chip 710 can use RFID (Radio Frequency Identification) technology to achieve mutual identification. RFID (Radio Frequency Identification) is a technology that uses radio frequency signals to achieve contactless information transmission through spatial coupling (alternating magnetic field or electromagnetic field), and achieves automatic identification through the transmitted information. The following are its specific principles and key technologies for achieving automatic identification:

[0075] Working principle:

[0076] Communication between tags and readers: An RFID system consists of tags, readers, and antennas. The tag contains an integrated circuit and an antenna, storing the information to be identified. The reader transmits radio frequency signals through the antenna. When the tag enters the reader's radio frequency field, the tag's antenna senses the signal, converts it into electrical energy to power the tag's chip, activating the chip and allowing it to transmit the stored information back to the reader as a radio frequency signal via the tag's antenna.

[0077] Signal modulation and demodulation: The signal sent by the reader needs to be modulated, loading the information to be transmitted onto a high-frequency carrier. The tag receives the signal, demodulates it, and extracts the information. The signal sent back by the tag to the reader also needs to be modulated; the reader receives it and then demodulates it to obtain the tag information.

[0078] Key technologies:

[0079] Radio frequency (RF) technology utilizes electromagnetic waves in the radio frequency band to transmit signals. Different frequency bands of RFID systems have their own characteristics and application scenarios. For example, low frequency (LF) systems have strong penetration and short identification distance, and are often used for animal identification; high frequency (HF) systems perform well in metallic and liquid environments and are suitable for library management; ultra-high frequency (UHF) systems have long identification distance and high speed, and are often used in logistics and retail.

[0080] Encoding and decoding technology: The information stored in the tag is encoded so that it can be accurately transmitted in the radio frequency signal. After the reader receives the signal, it decodes it to restore the original information. Common encoding methods include Manchester encoding and pulse position modulation encoding.

[0081] Anti-collision technology: When multiple tags are simultaneously within the reader's recognition range, signal collisions can occur. Anti-collision technology enables the reader to correctly identify each tag, such as the Aloha algorithm based on time division multiple access and binary search algorithms.

[0082] This design, by setting a first identification chip 13 inside the storage tank 10, allows the first identification chip 13 in the storage tank 10 and the fourth identification chip 710 in the material recycler 700 to be matched and identified before the recycled material is poured into the storage tank 10 by the material recycler 700. Only when the first identification chip 13 and the fourth identification chip 710 are correctly matched and identified can the material collected in the material recycler 700 be poured into the storage tank 10, thereby avoiding the phenomenon of mixing materials.

[0083] Please see Figures 5-8This application also proposes a battery production line 1000, which includes a mixing tank 200, a feeding pipeline 300, battery production equipment 400, a demagnetizing and recycling device 100, and a material recycling unit 700. The specific structure of the demagnetizing and recycling device 100 is as described in the above embodiments. Since this battery production line 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0084] The mixing tank 200 is equipped with a second identification chip 210; the inlet of the feeding pipe 300 is connected to the outlet of the mixing tank 200; the feeding pipe 300 is configured to supply materials to the battery production equipment 400; the feeding pipe 300 is equipped with a high-efficiency iron remover 500 and a filter structure 600, the high-efficiency iron remover 500 is configured to adsorb magnetic particles in the material flowing through the high-efficiency iron remover 500, and the filter structure 600 is configured to filter out impurities in the material flowing through the filter structure 600; a third identification chip 510 is installed in the high-efficiency iron remover 500 and the filter structure 600; the demagnetization return... The material collection device 100 has a storage tank 10 equipped with a first identification chip 13; the material recovery device 700 has a fourth identification chip 710. The material recovery device 700 is configured to collect materials attached to the high-efficiency iron remover 500 and the filter structure 600, and transfer the recovered materials to the storage tank 10; the material recovery device 700 is also configured to collect materials demagnetized by the demagnetizing recovery device 100, and transfer the materials to the mixing tank 200; wherein the first identification chip 13, the second identification chip 210 and the third identification chip 510 all recognize each other with the fourth identification chip 710.

[0085] Understandably, after the battery production line 1000 has been operating for a period of time, the material attached to the iron removal rods 520 and filter structure 600 of the high-efficiency iron remover 500 can be transferred to the storage tank 10 of the demagnetizing and recycling equipment 100 by manual or mechanical means. During this process, the third identification chip 510 in the high-efficiency iron remover 500 and filter structure 600 is first matched with the fourth identification chip 710 in the material collector 700. Only after the third identification chip 510 and the fourth identification chip 710 are correctly matched can the material collector 700 collect the material attached to the iron removal rods 520 and filter structure 600 of the high-efficiency iron remover 500. Then, the material collector 700 containing the collected material is moved to the vicinity of the storage tank 10, and the first identification chip 13 in the storage tank 10 is matched with the fourth identification chip 710 in the material collector 700. Only after the identification chip 710 is correctly matched and identified can the material collected in the material collector 700 be poured into the storage tank 10. After the material is processed by the demagnetizing recycling device 100, the material collector 700 is placed at the discharge pipe 60 of the demagnetizing recycling device 100, and the first identification chip 13 in the storage tank 10 and the fourth identification chip 710 in the material collector 700 are matched and identified. Only when the first identification chip 13 and the fourth identification chip 710 are correctly matched and identified can the material flow into the material collector 700. Then, the material collector 700 containing the material is moved to the vicinity of the mixing tank 200, and the second identification chip 210 in the mixing tank 200 and the fourth identification chip 710 in the material collector 700 are matched and identified. Only when the second identification chip 210 and the fourth identification chip 710 are correctly matched and identified can the material in the material collector 700 be poured into the mixing tank 200. The above design enables automatic identification of material recycling, transfer, demagnetization, and mixing processes, thereby achieving anti-mixing recycling of different products.

[0086] The mixing tank 200 is a container for storing and mixing raw materials. The top of the mixing tank 200 is provided with a feed inlet so that the user can smoothly pour the material into the mixing tank 200 from the feed inlet. In order to prevent external impurities from entering the mixing tank 200 from the feed inlet and contaminating the material, a sealing cover can be provided at the feed inlet. The sealing cover is used to open or close the feed inlet of the mixing tank 200.

[0087] The feeding pipeline 300 is used to transport the material in the mixing tank 200 to the battery production equipment 400 for battery production. The material flowing through the feeding pipeline 300 passes through a high-efficiency iron remover 500 and a filter structure 600. The high-efficiency iron remover 500 demagnetizes the material, and the filter structure 600 filters the material. The feeding pipeline 300 can be made of materials such as stainless steel, aluminum, or copper.

[0088] The filter structure 600 is installed on the feed pipe 300 to remove impurities (such as large particles like sand and mud) from the material flowing through it. The filter structure 600 can be installed upstream or downstream of the high-efficiency magnetic separator 500. Alternatively, to minimize the impact of impurities on the high-efficiency magnetic separator 500, the filter structure 600 can be installed upstream, allowing the material flowing through the feed pipe 300 to first pass through the filter structure 600 before passing through the high-efficiency magnetic separator 500. This allows the filter structure 600 to remove impurities before the high-efficiency magnetic separator 500 adsorbs magnetic particles.

[0089] The high-efficiency iron separator 500 is installed on the feeding pipeline 300 to adsorb magnetic particles in the material flowing through it. The high-efficiency iron separator 500 can use structures such as iron removal rods 520, magnetic sheets, and magnetic mesh to adsorb magnetic particles in the material.

[0090] Battery production equipment 400 is equipment for processing materials, such as equipment for processing battery positive electrodes.

[0091] The material recycling unit 700 is used to collect and transfer materials. The material recycling unit 700 can be a container such as a cylinder, a tray, or a tank, for example, a steel drum, an aluminum drum, etc.

[0092] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
