Description

Technical Field

[0001] This invention relates to the field of cryogenic crushing technology, and in particular to a fully enclosed cryogenic physical dismantling integrated production system. Background Technology

[0002] With the rapid development of new energy vehicles and energy storage industries, the recycling and disposal of waste lithium batteries has become a core issue in environmental protection and resource recycling. Lithium batteries contain flammable and explosive electrolytes and active materials. During traditional room-temperature crushing and dismantling processes, air ingress can cause oxidation reactions between the electrolyte and active materials, leading to combustion and explosion risks. Therefore, oxygen-free crushing and low-temperature dismantling of lithium batteries are crucial for ensuring dismantling safety and improving resource recovery rates. However, the crushing rollers in existing dismantling equipment are generally integrated structures, which easily leave battery fragments during crushing, resulting in uneven crushing and affecting dismantling efficiency. This necessitates manual cleaning after machine shutdown, which not only delays production but is also inconvenient. Furthermore, most oxygen-free systems have poor sealing, easily allowing air to enter during loading and unloading, and lack efficient low-temperature control and gas circulation mechanisms, resulting in high nitrogen consumption. During prolonged crushing, the surface temperature of the crushing rollers easily rises, making it difficult to maintain a low-temperature environment. This fails to meet the "safe, efficient, and low-consumption" dismantling requirements of lithium batteries, hindering the standardized development of the waste lithium battery recycling industry.

[0003] To address the above problems, this invention proposes a fully enclosed, low-temperature physical dismantling integrated production system. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of common crushing devices, where the crushing rollers are generally integrated structures, easily leaving battery fragments during the crushing process. This requires manual cleaning after the machine is stopped, which not only delays production but is also inconvenient. Furthermore, most oxygen-free systems have poor sealing, easily allowing air to mix in during loading and unloading, and lack efficient low-temperature control and gas circulation mechanisms, resulting in high nitrogen consumption. During long-term crushing, the surface temperature of the crushing rollers easily rises, making it difficult to maintain a low-temperature environment. Therefore, this invention proposes a fully enclosed low-temperature physical dismantling integrated production system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fully enclosed low-temperature physical dismantling integrated production system includes a processing mechanism, wherein a handling mechanism is provided in the processing mechanism; The processing mechanism includes a fixed base and a processing chamber. A nitrogen circulation assembly is provided on the processing chamber. Two cleaning assemblies are provided in the processing chamber. A feeding chamber and a discharging chamber are fixedly connected to the upper and lower sides of the processing chamber. The discharging chamber is fixedly connected to the fixed base. Adjustable sealing assemblies are provided in both the discharging chamber and the feeding chamber. The processing mechanism includes a drive assembly. The outer surface of the crushing roller of the drive assembly has multiple sets of circumferentially arranged cleaning ports. Each set of cleaning ports has multiple ports, and a crushing component is arranged in each cleaning port. Each set of crushing components is arranged in a corresponding guide rail, and the guide rail is fixedly connected to a fixed plate.

[0006] Preferably, the adjustable sealing assembly includes a fixing frame, two fixing frames are fixedly connected to each other, the lower fixing frame is fixedly connected to the fixing base, and the two fixing frames are respectively fixedly connected to the two discharge chambers and the feeding chamber.

[0007] Preferably, two electric push rods are installed on both the upper and lower sides of the fixed frame. One end of each electric push rod is fixedly connected to a sealing plate. The two upper sealing plates and the two lower sealing plates are respectively sealed in the feeding chamber and the discharging chamber.

[0008] Preferably, a vacuum device is installed on the lower fixing frame, and the two ends of the vacuum device are respectively connected to the feeding chamber and the discharging chamber.

[0009] Preferably, a gas detector and a nitrogen replenishment device are installed on the processing chamber.

[0010] Preferably, the cleaning assembly includes multiple fasteners, which are fixedly connected in the processing cavity and fixedly connected to the scraper.

[0011] Preferably, the nitrogen circulation assembly includes a circulating fan and a filter structure. The air inlet of the circulating fan is connected to the processing chamber through the filter structure, and the output port of the circulating fan is connected to a refrigeration device. The refrigeration device is connected to two output heads through output pipes, and the two output heads are installed in the processing chamber.

[0012] Preferably, the drive assembly includes a motor, two first gears, two crushing rollers, and two support shafts. The motor is installed in the processing chamber, and the output shaft of the motor is fixedly connected to a drive gear, which meshes with a driven gear. Both crushing rollers are rotatably mounted on two support shafts via two bearings. The driven gear and the two first gears are rotatably mounted on the support shaft (2015) via bearings connected to the crushing rollers. The two ends of the support shaft are fixedly connected in the processing cavity, and the two first gears mesh with each other.

[0013] Preferably, the crushing component includes crushing teeth, with the lower converging crushing teeth overlapping with the scraper. The crushing teeth are hinged in the cleaning port by a pin. A connector is fixedly connected to one side of the crushing teeth, and a connecting shaft is provided on the connector. The connecting shaft is slidably connected in the guide rail.

[0014] Preferably, the guide rail includes an outer arc segment and an inner arc segment, and the two ends of the inner arc segment and the outer arc segment are smoothly connected.

[0015] Compared with the prior art, the present invention provides a fully enclosed low-temperature physical dismantling integrated production system, which has the following beneficial effects: 1. This fully enclosed low-temperature physical dismantling integrated production system uses a drive component to drive the crushing component to crush and dismantle lithium batteries. As the crushing teeth move downwards, the connecting shaft enters the inner arc section, allowing the crushing teeth to enter the cleaning process. During the collection process, the teeth are cleaned through the cleaning port. After complete collection, the uncleaned side edges of the crushing teeth are cleaned again by a scraper. This allows for comprehensive and rapid cleaning of the crushing teeth, reducing cleaning difficulty and time. It also avoids problems such as crushing tooth jamming or uneven crushing gaps caused by the accumulation of lithium battery fragments, providing a uniform material basis for subsequent resource sorting.

[0016] 2. This fully enclosed low-temperature physical dismantling integrated production system can control the alternating sealing of the feeding and discharging chambers through adjustable sealing components, thereby achieving sealed loading and unloading. During loading and unloading, the sequential opening and closing of the upper and lower sealing plates, combined with vacuum equipment, effectively prevents oxygen from mixing in. The nitrogen circulation component can achieve nitrogen circulation and cooling, enabling recycling. The nitrogen circulation is sprayed from both sides of the processing chamber, directly cooling the process and avoiding temperature rise caused by frictional heat generation. At the same time, it inhibits electrolyte volatilization and active material oxidation, eliminating the risk of combustion and explosion during the crushing process and ensuring processing safety.

[0017] 3. This fully enclosed low-temperature physical dismantling integrated production system uses a drive component to drive a crushing component for crushing. The crushing component can move in the cleaning port in conjunction with a guide rail and perform self-cleaning in cooperation with the cleaning component, ensuring the continuous and stable crushing process. This avoids temperature fluctuations and gas leaks caused by intermediate crushing operations during cleaning, which would affect crushing efficiency and waste energy. The adjustable sealing component allows for alternating opening and closing of the upper and lower layers for sealed loading and unloading, and vacuum equipment is used for evacuation. At the same time, a nitrogen circulation component ensures low-temperature nitrogen circulation, providing stable working conditions for the cleaning component in an oxygen-free, low-temperature environment. The low temperature reduces the stickiness of lithium battery residues and decreases the adhesion of residues to the crushing roller surface. In addition, the clean crushing roller reduces frictional heat generation during the crushing process, reduces the cooling load of nitrogen, and further improves the economic efficiency of gas circulation, providing reliable technical support for the large-scale recycling of waste lithium batteries.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Example 1: Refer to Figures 1-8A fully enclosed, low-temperature physical dismantling integrated production system includes a processing mechanism 100. The processing mechanism 100 includes a fixed base 101 and a processing chamber 103. A gas detector 107 and a nitrogen replenishment device 110 are installed on the processing chamber 103. The gas detector 107 can detect the concentration of gases, and the nitrogen replenishment device 110 can replenish nitrogen in a timely manner when the nitrogen content decreases. A nitrogen circulation assembly 105 is provided on the processing chamber 103. The nitrogen circulation assembly 105 includes a circulating fan 1051 and a filter structure 1052. The filter structure 1052 can filter the extracted nitrogen and circulate it. The circulating fan 1051 enables the recycling of nitrogen in the processing chamber 103. The air inlet of the circulating fan 1051 is connected to the processing chamber 103 through the filter structure 1052. The output port of the circulating fan 1051 is connected to the refrigeration equipment 1053. The refrigeration equipment 1053 can pre-cool the output nitrogen to maintain the low temperature environment of the processing chamber 103, which is conducive to the safe dismantling of waste lithium batteries. The refrigeration equipment 1053 is connected to two output heads 1055 through the output pipe 1054. The two output heads 1055 are installed in the processing chamber 103. Two cleaning components 109 are provided in the processing chamber 103. The upper and lower sides of the processing cavity 103 are fixedly connected to the loading cavity 104 and the unloading cavity 102. The unloading cavity 102 is fixedly connected to the fixed base 101. Adjustable sealing assemblies 106 are evenly distributed in the unloading cavity 102 and the loading cavity 104. The adjustable sealing assembly 106 includes a fixing frame 1063. The two fixing frames 1063 are fixedly connected to each other. The lower fixing frame 1063 is fixedly connected to the fixed base 101, and the two fixing frames 1063 are fixedly connected to the two unloading cavities 102 and the loading cavity 104, respectively. Two electric push rods 1062 are installed on the upper and lower sides of the fixing frame 1063. The fixing frame 1063 can fix the electric push rods 1062 to ensure the stability of the electric push rods 1062, and the upper and lower electric push rods 1062 can be alternately controlled. The sealing plate 1061 is opened to ensure sealed operation of loading and unloading and reduce nitrogen loss and waste. One end of the two electric push rods 1062 is fixedly connected to the sealing plate 1061. The sealing plate 1061 can be sealed with the loading chamber 104 and the unloading chamber 102 to prevent nitrogen leakage. The two upper sealing plates 1061 and the two lower sealing plates 1061 are respectively sealed in the loading chamber 104 and the unloading chamber 102. A vacuum device 108 is installed on the lower fixed frame 1063. The vacuum device 108 can perform vacuum operation on the closed cavity of the two sealing plates 1061 to prevent oxygen from entering the processing chamber 103 and ensure a safe processing environment. The two ends of the vacuum device 108 are connected to the loading chamber 104 and the unloading chamber 102 respectively.

[0023] In this embodiment: the upper and lower sealing plates 1061 are switched open by adjusting the electric push rod 1062, thereby controlling the alternating sealing of the feeding chamber 104 and the discharging chamber 102 to achieve sealed loading and unloading. During loading and unloading, the sequential opening and closing of the upper and lower sealing plates 1061, combined with the vacuum operation of the vacuum equipment 108, effectively prevents the mixing of oxygen. The nitrogen circulation component 105 can realize the circulation and cooling of nitrogen, achieving recycling. The nitrogen circulation is sprayed from both sides of the processing chamber 103, directly cooling the temperature during processing, avoiding the temperature rise caused by frictional heat generation, and suppressing the volatilization of electrolyte and oxidation of active materials, so that there is no risk of combustion and explosion during the crushing process, ensuring processing safety.

[0024] Example 2: Refer to Figure 3 and Figures 7-12 A fully enclosed, low-temperature physical dismantling integrated production system includes a processing mechanism 200, which includes a drive assembly 201. The drive assembly 201 includes a motor 2011, two first gears 2014, two crushing rollers 2013, and two support shafts 2015. The motor 2011 is installed in a processing chamber 103. The output shaft of the motor 2011 is fixedly connected to a drive gear 2016, which meshes with a driven gear 2012. The two crushing rollers 2013 are rotatably mounted on the two support shafts 2015 via two bearings. The driven gears 2012 and the two first gears 2014 are rotatably mounted on the support shafts 2015 via bearings connected to the crushing rollers 2013. The crushing roller 2013 and the first gear 2014 are connected to the same bearing. At the same time, the crushing roller 2013 is also connected to the driven gear 2012 through the bearing. The movement of the driven gear 2012 can smoothly drive the crushing roller 2013 to rotate, and drive the first gear 2014 to achieve the purpose of transmission. The two ends of the support shaft 2015 are fixedly connected in the processing cavity 103. The two first gears 2014 mesh with each other. The motor 2011 drives the drive gear 2016 to rotate, so that the drive gear 2016 and the driven gear 2012 are transmitted, thereby causing the crushing roller 2013 to rotate. Under the meshing transmission of the two first gears 2014, the two crushing rollers 2013 rotate synchronously, thereby causing the crushing teeth 2021 to move to perform crushing and dismantling operations. The crushing roller 2013 of the drive assembly 201 has multiple sets of circumferentially arranged cleaning ports 203 on its outer surface. Each set of cleaning ports 203 contains multiple components, and each cleaning port 203 houses a crushing component 202. The crushing component 202 includes crushing teeth 2021. The lower, retracted crushing teeth 2021 overlap with the scraper 1092. When the crushing teeth 2021 are fully retracted for cleaning and remain on the same plane as the crushing roller 2013, the scraper 1092 can smoothly clean the side edges of the crushing teeth 2021. The crushing teeth 2021 are hinged in the cleaning ports 203 by pins, allowing them to rotate. A connecting member 2023 is fixedly connected to one side of the crushing teeth 2021. A connecting shaft 2022 is provided on the connecting member 2023 and slidably connected in the guide rail 205. The rail 205 includes an outer arc segment 2051 and an inner arc segment 2052. The two ends of the inner arc segment 2052 and the outer arc segment 2051 are smoothly connected. Through the smooth connection of the outer arc segment 2051 and the inner arc segment 2052 with different centers, the connecting shaft 2022 can slide smoothly in the outer arc segment 2051 and the inner arc segment 2052. When entering the inner arc segment 2052, the connecting shaft 2022 can smoothly drive the crushing teeth 2021 into the cleaning port 203 for self-cleaning. When the connecting shaft 2022 enters the inner arc segment 2052, the crushing teeth 2021 are reset. The crushing teeth 2021 in the outer arc segment 2051 are kept in the crushing area, so as to stably realize the crushing operation of waste lithium batteries. Each set of crushing components 202 is respectively set in the corresponding guide rail 205. The guide rail 205 is fixedly connected to the fixed plate 204. The cleaning assembly 109 includes a plurality of fasteners 1091, which are fixedly connected in the processing cavity 103 and are fixedly connected to the scraper 1092.

[0025] In this embodiment: the crushing component 202 is driven by the driving component 201 to crush and disassemble the lithium battery. As the crushing tooth 2021 moves downward, the connecting shaft 2022 enters the inner arc section 2052, allowing the crushing tooth 2021 to move through the pin and be drawn into the cleaning port 203. The process of the crushing tooth 2021 being drawn into the cleaning port 203 can be cleaned. After it is completely drawn in, the side edges of the crushing tooth 2021 that have not been cleaned are cleaned again by the scraper 1092. This allows for a comprehensive and rapid cleaning of the crushing tooth 2021, reducing the difficulty and time of cleaning. At the same time, it avoids the problem of the crushing tooth 2021 getting stuck or the crushing gap being uneven due to the accumulation of lithium battery fragments, providing a uniform material basis for subsequent resource sorting.

[0026] Example 3: Reference Figures 1-6 and Figure 11A fully enclosed low-temperature physical dismantling integrated production system includes a processing mechanism 100. The processing mechanism 100 includes a fixed base 101 and a processing chamber 103. A nitrogen circulation component 105 is provided on the processing chamber 103. Two cleaning components 109 are provided in the processing chamber 103. A feeding chamber 104 and a discharging chamber 102 are fixedly connected to the upper and lower sides of the processing chamber 103. The discharging chamber 102 is fixedly connected to the fixed base 101. Adjustable sealing components 106 are evenly distributed in the discharging chamber 102 and the feeding chamber 104. The processing mechanism 200 includes a drive assembly 201. The crushing roller 2013 of the drive assembly 201 has multiple sets of circumferentially arranged cleaning ports 203 on its outer surface. Each set of cleaning ports 203 has multiple ports, and each cleaning port 203 is provided with a crushing component 202. Each set of crushing components 202 is respectively arranged in a corresponding guide rail 205, and the guide rail 205 is fixedly connected to the fixed plate 204.

[0027] In this embodiment: the crushing component 202 is driven by the driving component 201 to perform crushing processing, and the crushing component 202 can move in the cleaning port 203 in conjunction with the guide rail 205 and perform self-cleaning in cooperation with the cleaning component 109, ensuring the continuous and stable crushing process and avoiding interruption of crushing operation due to cleaning needs, which would lead to temperature fluctuations and gas leakage, affecting crushing efficiency and causing energy waste. The upper and lower layers are alternately opened and closed by the adjustable sealing component 106 to seal the loading and unloading, and vacuum equipment 108 is used to evacuate the vacuum. At the same time, the nitrogen circulation component 105 ensures the low-temperature circulation of nitrogen, so that the oxygen-free low-temperature environment provides stable working conditions for the cleaning component 109. The low temperature can reduce the stickiness of lithium battery residues and reduce the adhesion of residues to the surface of the crushing roller 2013. At the same time, the clean crushing roller 2013 reduces the frictional heat generated during the crushing process, reduces the cooling load of nitrogen, and further improves the economic efficiency of gas circulation, providing reliable technical support for the large-scale recycling of waste lithium batteries.

[0028] Working principle: When performing lithium battery dismantling, waste lithium batteries are put into the feeding chamber 104 and fall onto the lower sealing plate 1061. Then, the electric push rod 1062 controls the upper sealing plate 1061 to close the feed inlet of the feeding chamber 104. At this time, the vacuum equipment 108 performs vacuuming, and then the lower sealing plate 1061 is opened to allow the waste lithium batteries to enter the processing chamber 103. Then the lower sealing plate 1061 is closed again to prepare for the next feeding operation. Nitrogen gas is filtered through the filter structure 1052 by the circulating fan 1051, and then cooled by the refrigeration equipment 1053. After cooling, the nitrogen gas is discharged from both sides through the output head 1055 to maintain a low-temperature dismantling environment. Next, the motor 2011 drives the active gear 2016 and the driven gear 2012 to mesh and transmit power, so that the driven gear 2012 drives the crushing roller 2013 to rotate. The transmission of the two first gears 2014 can ensure that the two crushing rollers 2013 rotate, so that the crushing teeth 2021 crush and dismantle the waste lithium battery. During the crushing and dismantling process, the crushing tooth 2021 moves downwards in a cycle, and the connecting shaft 2022 enters the inner arc section 2052, causing the crushing tooth 2021 to move through the pin shaft. When the crushing tooth 2021 enters the cleaning port 203 for cleaning, after the crushing tooth 2021 is completely retracted for cleaning, one side of the edge of the crushing tooth 2021 is cleaned by the scraper 1092. After cleaning, the connecting shaft 2022 enters the outer arc section 2051, at which point the crushing tooth 2021 is reset, thus performing a cyclic crushing operation. The disassembled battery enters the lower sealing plate 1061, and then the upper sealing plate 1061 closes the processing chamber 103. At this time, the lower sealing plate 1061 moves to open the discharge chamber 102 for discharge. After discharge, the sealing plate 1061 is closed. Then, a vacuum is drawn again, and the upper sealing plate 1061 is opened to prepare for the next discharge operation.

[0029] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
