Description

[0002] Lithium batteries are widely used in mobile phones, electric vehicles, laptops, portable electronic devices and other fields. As the number of charge and discharge cycles increases, the capacity of lithium batteries gradually decreases. When the capacity of lithium batteries decreases to a certain level, the batteries can no longer meet normal use needs and become waste batteries. In order to reduce pollution, save resources or improve energy efficiency, waste batteries are usually recycled.

[0003] Existing waste battery recycling technology, such as the patent with authorization announcement number CN115036608B, discloses a waste battery electrolyte recovery and classification device, which turns on the motor to rotate the blade, and pours the battery into the feeding frame so that the blade crushes the battery, and then the electrolyte in the battery can be fully discharged, so as to achieve the purpose of facilitating recycling and classification.

Detailed embodiments

[0026] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent a limitation on the scope of the present invention as defined by the appended claims. Any numerical labels such as first or second are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0027] A fully enclosed collection device for waste lithium battery electrolyte based on centrifugal force, as Figures 1 - 10 shown, which includes a frame 101. A processing cylinder 102 is fixedly connected to the top of the frame 101. The bottom of the processing cylinder 102 is rotatably connected in a sealed manner to a rotating cylinder. The rotating cylinder is driven by a driving assembly to achieve rotation. An inner cylinder 103 is fixedly connected to the middle part inside the processing cylinder 102. A shredding assembly for shredding the battery is arranged in the middle part of the inner cylinder 103. The upper part of the inner cylinder 103 is a feed port 1031, and the lower part is a blanking port 1032. A cylinder cover 104 is arranged at the feed port 1031. The rotating cylinder includes an air-gathering cylinder 105 and a centrifugal cylinder 106. The centrifugal cylinder 106 is rotatably connected to the frame 101. The air-gathering cylinder 105 is arranged between the processing cylinder 102 and the centrifugal cylinder 106. The upper and lower ends of the air-gathering cylinder 105 are respectively sealed and connected to the processing cylinder 102 and the centrifugal cylinder 106. A first filter screen 131 is fixedly connected inside the centrifugal cylinder 106. A tipping assembly is arranged at the bottom inside the centrifugal cylinder 106. The tipping assembly is connected to the shredding assembly. A partition plate 201 is fixedly connected inside the processing cylinder 102. A moving cylinder 202 is slidably connected in a sealed manner below the partition plate 201. A reciprocating thread groove 1051 is arranged on the inner side wall of the air-gathering cylinder 105. A thread protrusion 2021 that cooperates with the reciprocating thread groove 1051 is arranged on the outer side wall of the moving cylinder 202. It should be noted that the connection relationship between the reciprocating thread groove 1051 and the thread protrusion 2021 is a sealed connection. Specifically, flexible sealing rings (such as rubber) can be added to the contact surface of the reciprocating movement. These sealing rings can generate appropriate compression and elastic deformation during the thread operation to ensure the sealing of the thread connection. At the same time, since the thickness of the moving cylinder 202 is greater than the length between the upper and lower parts of the reciprocating thread groove 1051, the side wall of the moving cylinder 202 can always maintain a seal with the processing cylinder 102 to prevent gas from entering the inside of the processing cylinder 102 through the reciprocating thread groove 1051. At the same time, at least one turn of the thread protrusion 2021 is arranged to prevent residual gas in the reciprocating thread groove 1051. At the same time, a clamping plate 141 is fixedly connected to the side wall of the inner cylinder 103. A linear groove 2023 that cooperates with the clamping plate 141 is arranged on the moving cylinder 202. In this way, the moving cylinder 202 can perform a reciprocating linear motion. The partition plate 201 and the moving cylinder 202 divide the processing cylinder 102 into a liquid storage chamber 1021 and a processing chamber 1022. The liquid storage chamber 1021 stores a processing liquid, and the processing liquid is specifically a sodium bicarbonate solution. The sodium bicarbonate solution can neutralize some acidic gases, such as hydrogen fluoride. A water inlet 2011 is circumferentially arranged on the partition plate 201. A plugging assembly that cooperates with the moving cylinder 202 is arranged on the water inlet 2011. A first air inlet hole 2022 is circumferentially arranged on the moving cylinder 202. A one-way valve is arranged on the first air inlet hole 2022.

[0028] It can be seen from this that the barrel cover 104 is opened, a certain amount of scrapped lithium batteries are put into the device from the feed inlet 1031, and then the barrel cover 104 is covered. At the same time, the driving component and the shredding component are started. The shredding component shreds the scrapped lithium batteries, and the shredded material falls above the dumping component from the blanking port 1032. The driving component drives the rotating cylinder to rotate, and then the centrifugal cylinder 106 rotates to separate the lithium battery fragments and the electrolyte. The electrolyte will be thrown to the periphery inside the centrifugal cylinder 106 due to its strong fluidity, while other solid fragments are intercepted by the first filter screen 131 and thus remain above the dumping component. During the process of crushing and centrifuging the electrolyte, lithium hexafluorophosphate will decompose to generate gases such as hydrogen fluoride. Due to the rotation of the rotating cylinder, the gas collecting cylinder 105 drives the moving cylinder 202 to perform a reciprocating linear motion through the reciprocating thread groove 1051. When the moving cylinder 202 moves downward, a negative pressure is generated in the treatment chamber 1022, and then the treatment chamber 1022 sucks the gas from the first air inlet hole 2022. When the moving cylinder 202 moves downward, the blocking component will be opened, so that the treatment liquid in the liquid storage chamber 1021 flows into the treatment chamber 1022 from the water inlet 2011 to react with the gas, thus ensuring that the gas will not leak and reducing the safety risk. It should be added that since the sodium bicarbonate solution is used to neutralize gases such as hydrogen fluoride, its reaction process usually does not depend on temperature. Therefore, the sodium bicarbonate solution can be controlled at a lower temperature. The solubility of hydrogen fluoride gas usually increases at low temperatures, which helps to increase the ability of sodium bicarbonate to absorb hydrogen fluoride gas and reduce gas volatilization. At the same time, the generated sodium fluoride can usually be dissolved in the solution, so no precipitation will occur.

[0029] Furthermore, in order to facilitate the accumulation of gas and make the air suction effect in the treatment chamber 1022 better, the driving component includes a first worm gear 301 and a second worm gear 302 respectively fixed on the outer side walls of the gas collecting cylinder 105 and the centrifugal cylinder 106. A first worm 303 and a second worm 304 are rotatably connected to the frame 101. The first worm 303 meshes with the first worm gear 301, and the second worm 304 meshes with the second worm gear 302. The second worm 304 is driven by a driving motor 305 to rotate. The first worm 303 and the second worm 304 are connected to each other through a synchronous belt component 306. The diameters of the two synchronous wheels in the synchronous belt component 306 are in a proportional relationship, and the diameter of the synchronous wheel connected to the second worm 304 is the shortest. Among them, both the gas collecting cylinder 105 and the centrifugal cylinder 106 are rotatably connected to the frame 101. In this way, while the centrifugal cylinder 106 is rotating at a high speed, the gas collecting cylinder 105 can be driven to rotate at a relatively slow speed through the synchronous belt component 306. A connecting ring 111 is provided at the center of the inner bottom of the gas collecting cylinder 105. The inner wall of the connecting ring 111 is in sealed contact with the outer wall of the first filter screen 131. A guide plate 112 is fixed between the connecting ring 111 and the gas collecting cylinder 105, and the guide plate 112 is inclined. It can be seen from this that when the drive motor 305 is started, the output shaft of the drive motor 305 drives the second worm 304 to rotate. The second worm 304 drives the second worm gear 302 to rotate through meshing transmission, thereby causing the centrifugal cylinder 106 to rotate, and thus achieving the centrifugal effect. The second worm 304 drives the first worm 303 to rotate through the synchronous belt component 306. The first worm 303 drives the first worm gear 301 to rotate through meshing transmission, thereby causing the air collecting cylinder 105 to rotate. Since the diameters of the two synchronous wheels in the synchronous belt component 306 are in a proportional relationship, and the diameter of the synchronous wheel connected to the second worm 304 is the shortest, the rotation speed of the centrifugal cylinder 106 is much greater than that of the air collecting cylinder 105. On the one hand, it can protect the cooperation between the reciprocating thread groove 1051 and the thread protrusion 2021 to prevent the equipment from failing due to high-speed rotation. On the other hand, since the air collecting cylinder 105 rotates, the deflector 112 rotates accordingly. The rotation of the deflector 112 can guide the gas to the position between the upper part of the deflector 112 of the air collecting cylinder 105 and the lower part of the moving cylinder 202, improving the gas separation effect in the centrifugal cylinder 106, ensuring more thorough separation of the electrolyte and the gas. At the same time, when the moving cylinder 202 moves downward, it can inhale the gas more efficiently, thereby better promoting the reaction between the gas and the treatment liquid and enhancing the negative pressure effect in the treatment chamber 1022.

[0030] Furthermore, in order to accurately adjust the water inlet 2011, the blocking assembly includes a second fixing rod 401 symmetrically fixed to the water inlet 2011, a blocking block 402 is slidably connected to the second fixing rod 401, and the blocking block 402 is provided with an inclined surface matching the water inlet 2011, a first elastic member 403 is provided between the blocking block 402 and the second fixing rod 401, and the first elastic member 403 is specifically a spring, and a first L-shaped block is fixed to the bottom surface of the blocking block 402. 404, a second L-shaped block 405 matching with the first L-shaped block 404 is fixedly connected to the top surface of the moving cylinder 202, and the second L-shaped block 405 is inverted, and a certain distance is set between the crossbar of the first L-shaped block 404 and the crossbar of the second L-shaped block 405. It can be seen that when the moving cylinder 202 moves downward, it will drive the second L-shaped block 405 to move downward. After moving a certain distance, the second L-shaped block 405 contacts the first L-shaped block 404, thereby making the second L-shaped block 405 The second L-shaped block 405 pulls the first L-shaped block 404 to move downward, thereby driving the blocking block 402 to move downward, and then the blocking block 402 squeezes the first elastic member 403, so that the first elastic member 403 stores elastic potential energy, thereby connecting the liquid storage chamber 1021 with the processing chamber 1022, so that the processing liquid in the liquid storage chamber 1021 falls into the processing chamber 1022, and when the moving cylinder 202 moves upward, the second L-shaped block 405 is no longer in contact with the first L-shaped block 404, and then the first elastic member 403 releases elastic potential energy, and the first elastic member 403 drives the blocking block 402 to reset, and then the blocking block 402 blocks the water inlet 2011, so that the processing liquid no longer falls into the processing chamber 1022. In this way, through the cooperation between the blocking block 402 and the first elastic member 403, it is ensured that the inflow of the processing liquid each time can match the amount of the inhaled gas, thereby achieving accurate allocation of gas and liquid, and avoiding too much or too little processing liquid from entering the processing chamber 1022.

[0031] Furthermore, in order to enable the processing liquid to react fully with the gas, a stirring assembly is circumferentially arranged in the processing chamber 1022. The stirring assembly includes a first fixing rod 701 fixedly connected to the bottom surface of the partition plate 201 circumferentially with the inner cylinder 103 as the center. The first fixing rod 701 is hollow, and a rotating rod 702 is slidably connected to the inside of the first fixing rod 701 in a sealed manner. One end of the rotating rod 702 is rotatably connected to the top surface of the moving cylinder 202. A stirring rod 703 is fixedly connected to the rotating rod 702. A threaded groove 7011 is provided on the inner side wall of the first fixing rod 701, and the bottom of the threaded groove 7011 is provided with a gap from the bottom of the first fixing rod 701. In this way, the sealing performance between the first fixing rod 701 and the rotating rod 702 can be ensured, preventing the processing liquid or gas from entering the threaded groove 7011. A clamping ball 704 is fixedly connected to the side wall of the rotating rod 702 and is matched with the threaded groove 7011. It can be seen that when the moving cylinder 202 moves downward, the rotating rod 702 will be driven to move downward. Furthermore, the clamping ball 704 makes the rotating rod 702 rotate through the cooperation with the threaded groove 7011. The rotation of the rotating rod 702 drives the stirring rod 703 to rotate, so that the gas and liquid can be in full contact, which helps to accelerate the processing efficiency of harmful gases such as hydrogen fluoride.

[0032] Furthermore, in order to prevent gas from accumulating in the inner cylinder 103, a second air inlet hole 1033 is circumferentially arranged on the inner wall of the inner cylinder 103 at the position of the processing chamber 1022. A one-way valve and a filter screen are arranged on the second air inlet hole 1033. It can be seen that when the waste battery is crushed, a small amount of gas decomposed from the electrolyte will stay in the inner cylinder 103. When a negative pressure is generated in the processing chamber 1022, the processing chamber 1022 will suck the small amount of gas in the inner cylinder 103 through the second air inlet hole 1033, avoiding the accumulation of gas in the inner cylinder 103. The filter screen can prevent dust from entering the processing chamber 1022.

[0033] Furthermore, collecting boxes 801 are symmetrically and fixedly connected to the outer side wall of the processing cylinder 102. The collecting boxes 801 are communicated with the processing chamber 1022 through discharge pipes 802. One-way valves are arranged in the discharge pipes 802. An activated carbon plate 803 is connected to the top of the inside of the collecting boxes 801. It can be seen that as the processing liquid in the processing chamber continuously increases, when the moving cylinder 202 moves upward, the reacted processing liquid and the processed gas will be discharged from the discharge pipes 802, avoiding potential safety hazards caused by the accumulation of gas and liquid. At the same time, the reacted processing liquid is collected through the collecting boxes 801, and the processed gas is discharged through the filtration of the activated carbon plate 803.

[0034] Furthermore, in order to cut waste batteries more efficiently, the shredding assembly includes a rotating shaft 501 disposed at the center of the inner cylinder 103. The rotating shaft 501 is rotatably connected to the top of the frame 101. A variable-diameter spiral cutter 502 is fixedly connected to the outer side wall of the rotating shaft 501. The diameter of the variable-diameter spiral cutter 502 gradually increases from top to bottom. A fixed cutter 503 that cooperates with the variable-diameter spiral cutter 502 is fixedly connected to the inner side wall of the inner cylinder 103. The tipping assembly includes bases 601 symmetrically fixedly connected to the bottom of the frame 101. A moving block 602 is slidably connected inside the base 601. The moving block 602 is driven by a driving member to achieve sliding. The driving member can specifically be an electric push rod (not shown in the figure) installed inside the base 601. A disc 603 is rotatably connected between the two moving blocks 602. A torsion spring is provided between the disc 603 and the moving block 602. A top rod 605 that cooperates with the disc 603 is fixedly connected between the two bases 601. A raising platform 606 is rotatably connected to the top surface of the disc 603. Clamping blocks 611 are circumferentially arranged on the side wall of the raising platform 606. The clamping blocks 611 are slidably connected to the side wall of the raising platform 606. A second elastic member 612 is provided between the clamping blocks 611 and the raising platform 606. The second elastic member 612 is specifically a spring. A clamping groove 1061 that cooperates with the clamping blocks 611 is provided at the bottom of the centrifugal cylinder 106. Inclined surfaces are provided on both the upper and lower side surfaces of the clamping blocks 611, so that the clamping blocks 611 can be smoothly clamped into the clamping groove 1061. A cross block 613 is fixedly connected to the top surface of the raising platform 606. A groove 5011 that cooperates with the cross block 613 is provided on the bottom surface of the rotating shaft 501; It can be seen from this that the cylinder cover 104 is opened, a certain amount of scrapped lithium batteries are put into the device from the feed port 1031, then the cylinder cover 104 is covered, and then the driving motor 305 is started. The driving motor 305 drives the centrifugal cylinder 106 to rotate. Further, the centrifugal cylinder 106 drives the raising platform 606 to rotate through the connection relationship such as the clamping blocks 611. The raising platform 606 drives the rotating shaft 501 to rotate through the connection relationship such as the cross block 613. Further, the variable-diameter spiral cutter 502 rotates. The variable-diameter spiral cutter 502 cooperates with the fixed cutter 503 to cut the waste batteries into pieces. The shredded waste batteries fall onto the top surface of the raising platform 606 and are centrifuged in cooperation with the rotation of the centrifugal cylinder 106. After the centrifugation is completed, the device stops. Then, the electrolyte in the centrifugal cylinder 106 is taken out first. After the electrolyte is taken out, the driving member is started again, so that the disc 603 moves downward. While the disc 603 moves downward, it drives the raising platform 606 and the battery debris on the raising platform 606 to move downward together. As the disc 603 moves downward, the top rod 605 will lift one side of the disc 603, thereby tilting the disc 603 and storing elastic potential energy in the torsion spring, as Figure 10As shown, the battery debris on the elevation platform 606 slides off the elevation platform 606 under the action of gravity. In this way, by additionally placing a collection box, the battery debris can be collected. After the processing is completed, the driving member is activated, causing the disc 603 to move upward. Then, the torsion spring drives the disc 603 to reset, and the latch 611 is reinserted into the card slot 1061. At the same time, the cross block 613 can also be inserted into the groove 5011. It should be added that while the disc 603 is tilted, the cleaning device can be used to clean the elevation platform 606. On the one hand, it prevents debris from accumulating on the elevation platform 606, and on the other hand, it prevents debris from being caught at the cross block 613 and affecting the rotating shaft 501.
