Description

Technical Field

[0002] Lithium batteries are widely used in mobile phones, electric vehicles, laptops, and portable electronic devices. However, as the number of charge and discharge cycles increases, the capacity of lithium batteries gradually decreases. Once the capacity drops to a certain level, the battery can no longer meet normal usage requirements and becomes waste. To reduce pollution, conserve resources, or improve energy efficiency, waste batteries are often recycled.

[0027] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those skilled in the art will recognize that terms such as "above," "below," "upwardly," "downwardly," and the like are used to describe the drawings and are not intended to limit the scope of the present invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0028] A fully enclosed collection device for scrapped lithium battery electrolyte based on centrifugal force, such as Figures 1-10As shown, it includes a frame 101, a processing cylinder 102 is fixedly connected to the top of the frame 101, and a rotating cylinder is sealed and rotatably connected to the bottom of the processing cylinder 102. The rotating cylinder is driven to rotate by a driving assembly. An inner cylinder 103 is fixedly connected to the middle of the processing cylinder 102. A shredding assembly for shredding batteries is provided in the middle of the inner cylinder 103. The upper part of the inner cylinder 103 is a feed port 1031, and the lower part is a drop port 1032. A cylinder cover 104 is provided at the feed port 1031. The rotating cylinder includes a gas collecting cylinder 105 and a centrifugal cylinder 106. The centrifugal cylinder 106 is rotatably connected to the frame 101. The gas collecting cylinder 105 is provided between the processing cylinder 102 and the centrifugal cylinder 106. The upper and lower ends of the gas collecting cylinder 105 are sealedly connected to the processing cylinder 102 and the centrifugal cylinder 106 respectively. A first filter screen 131 is fixedly connected to the centrifugal cylinder 106. A dumping assembly is provided at the bottom of the centrifugal cylinder 106. The dumping assembly is connected to the chopping assembly. A partition 201 is fixedly connected to the processing cylinder 102. A moving cylinder 202 is sealed and slidably connected below the partition 201. A reciprocating thread groove 1051 is provided on the inner wall of the gas collecting cylinder 105, and a threaded protrusion 2021 that matches the reciprocating thread groove 1051 is provided on the outer wall of the moving cylinder 202. It should be noted that the connection relationship between the reciprocating thread groove 1051 and the threaded protrusion 2021 is a sealed connection. The body can add flexible sealing rings (such as rubber) on the contact surface of the reciprocating motion. These sealing rings can produce appropriate compression and elastic deformation with the movement when the thread is running, ensuring the sealing of the threaded 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 interior of the processing cylinder 102 through the reciprocating thread groove 1051. At the same time, the thread protrusion 2021 is provided with at least one circle to prevent gas from remaining in the reciprocating thread groove 1051. At the same time, a card plate 141 is fixed to the side wall of the inner cylinder 103, and the moving cylinder 20 2 is provided with a linear groove 2023 that cooperates with the clamping plate 141, so that the movable cylinder 202 can perform reciprocating linear motion. The partition 201 and the movable cylinder 202 separate the treatment cylinder 102 into a liquid storage chamber 1021 and a treatment chamber 1022. The liquid storage chamber 1021 stores the treatment liquid, which 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 provided on the partition 201, and a sealing component that cooperates with the movable cylinder 202 is provided on the water inlet 2011. A first air inlet 2022 is circumferentially provided on the movable cylinder 202, and a one-way valve is provided on the first air inlet 2022.

[0029] It can be seen that the cylinder cover 104 is opened, a certain amount of scrapped lithium batteries are put into the device from the feed port 1031, and then the cylinder cover 104 is closed, and the driving component and the shredding component are started at the same time. The shredding component shreds the scrapped lithium batteries, and the shredded material falls from the drop port 1032 to the top of the dumping component. 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 of the centrifugal cylinder 106 due to its strong fluidity, while other solid fragments are intercepted by the first filter 131 and thus remain above the dumping component. During the process of crushing and centrifuging the electrolyte, lithium hexafluorophosphate will decompose to produce gases such as hydrogen fluoride, and due to the rotation of the rotating cylinder, the gas collecting cylinder 105 drives the moving cylinder 202 to move back and forth in a straight line through the reciprocating thread groove 1051. When the movable cylinder 202 moves downward, negative pressure is generated in the processing chamber 1022, so that the processing chamber 1022 sucks the gas from the first air inlet 2022, and the downward movement of the movable cylinder 202 will open the blocking component, so that the processing liquid in the liquid storage chamber 1021 flows from the water inlet 2011 into the processing chamber 1022 to react with the gas, thereby ensuring that the gas will not leak out and reducing safety risks. It should be noted that since the sodium bicarbonate solution is used to neutralize gases such as hydrogen fluoride, its reaction process is usually not dependent on temperature, and 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 sodium fluoride generated can usually be dissolved in the solution, so no precipitation will be produced.

[0030] Furthermore, in order to facilitate gas accumulation and improve the suction effect in the processing chamber 1022, the driving assembly includes a first worm gear 301 and a second worm gear 302 respectively fixed to the outer walls of the gas collecting cylinder 105 and the centrifugal cylinder 106, and the frame 101 is rotatably connected to the first worm 303 and the second worm 304. The first worm 303 is meshed with the first worm gear 301, and the second worm 304 is meshed with the second worm gear 302. The second worm 304 is driven by the driving motor 305 to rotate. The first worm 303 and the second worm 304 are connected to each other by a synchronous belt component 306, wherein the synchronous The diameters of the two synchronous wheels in the belt component 306 are proportional, and the synchronous wheel connected to the second worm 304 has the shortest diameter. The gas collecting cylinder 105 and the centrifugal cylinder 106 are both rotatably connected to the frame 101. In this way, while the centrifugal cylinder 106 rotates at a high speed, the gas collecting cylinder 105 can be driven by the synchronous belt component 306 to rotate at a relatively slow speed. A connecting ring 111 is provided at the center of the bottom of the gas collecting cylinder 105. The inner wall of the connecting ring 111 is in sealing contact with the outer wall of the first filter screen 131. A guide plate 112 is fixedly connected between the connecting ring 111 and the gas collecting cylinder 105, and the guide plate 112 is arranged at an angle.

[0031] It can be seen that when the drive motor 305 is started, the output shaft of the drive motor 305 drives the second worm 304 to rotate, and the second worm 304 drives the second worm wheel 302 to rotate through meshing transmission, thereby rotating the centrifugal cylinder 106, thereby achieving a centrifugal effect, and the second worm 304 drives the first worm 303 to rotate through the synchronous belt component 306, and the first worm 303 drives the first worm wheel 301 to rotate through meshing transmission, thereby rotating the gas collecting cylinder 105, and since the diameters of the two synchronous wheels in the synchronous belt component 306 are proportional, the diameter of the synchronous wheel connected to the second worm 304 is the shortest, thereby making the rotation speed of the centrifugal cylinder 106 It is much larger than the gas 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 high-speed rotation from causing equipment failure. On the other hand, due to the rotation of the gas collecting cylinder 105, the guide plate 112 is rotated. The rotation of the guide plate 112 can guide the gas to the position between the top of the guide plate 112 of the gas collecting cylinder 105 and the bottom of the moving cylinder 202, thereby improving the gas separation effect in the centrifugal cylinder 106 and ensuring a more thorough separation of the electrolyte and gas. At the same time, when the moving cylinder 202 moves downward, it can more efficiently inhale the gas, thereby better promoting the reaction between the gas and the processing liquid and enhancing the negative pressure effect in the processing chamber 1022.

[0032] Furthermore, in order to accurately adjust the water inlet amount of 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 that matches the water inlet 2011. A first elastic member 403 is provided between the blocking block 402 and the second fixing rod 401. The first elastic member 403 is specifically a spring. The bottom surface of the blocking block 402 is fixed with a first L-shaped block. 404, the top surface of the moving cylinder 202 is fixed with a second L-shaped block 405 that matches the first L-shaped block 404. The second L-shaped block 405 is set upside down, 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. When the movable cylinder 202 moves upward, the second L-shaped block 405 no longer contacts 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 of the blocking block 402 and the first elastic member 403, it is ensured that the inflow of processing liquid each time can match the amount of inhaled gas, thereby achieving precise adjustment of gas and liquid, and avoiding too much or too little processing liquid entering the processing chamber 1022.

[0033] Furthermore, in order to make the processing liquid and the gas fully react, a stirring assembly is also circumferentially provided in the processing chamber 1022. The stirring assembly includes a first fixed rod 701 circumferentially fixed to the bottom surface of the partition 201 with the inner cylinder 103 as the center. The first fixed rod 701 is hollow. A rotating rod 702 is sealingly and slidably connected inside the first fixed rod 701. One end of the rotating rod 702 is rotatably connected to the top surface of the moving cylinder 202. A stirring rod 703 is fixed to the rotating rod 702. A threaded groove 7011 is provided on the inner side wall of the first fixed rod 701, and a gap is set between the bottom of the threaded groove 7011 and the bottom of the first fixed rod 701. The arrangement can ensure the sealing between the first fixed rod 701 and the rotating rod 702, and prevent the processing liquid or gas from entering the thread groove 7011. A card ball 704 that cooperates with the thread groove 7011 is fixed to the side wall of the rotating rod 702. It can be seen that when the movable cylinder 202 moves downward, it will drive the rotating rod 702 to move downward, and then the card ball 704 cooperates with the thread groove 7011 to make the rotating rod 702 rotate. The rotation of the rotating rod 702 drives the stirring rod 703 to rotate, so that the gas and liquid can be fully contacted, which helps to accelerate the treatment efficiency of harmful gases such as hydrogen fluoride.

[0034] Furthermore, in order to prevent gas accumulation 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 processing chamber 1022, and a one-way valve and a filter are provided on the second air inlet hole 1033. It can be seen that when the waste batteries are crushed, the electrolyte will decompose a small amount of gas and remain in the inner cylinder 103. When a negative pressure is generated in the processing chamber 1022, the processing chamber 1022 will inhale a small amount of gas in the inner cylinder 103 through the second air inlet hole 1033 to avoid gas accumulation in the inner cylinder 103. The filter can prevent dust from entering the processing chamber 1022.

[0035] Furthermore, a collection box 801 is symmetrically fixed on the outer wall of the treatment cylinder 102. The collection box 801 is connected to the treatment chamber 1022 through a discharge pipe 802. A one-way valve is provided in the discharge pipe 802. An activated carbon plate 803 is connected to the top of the collection box 801. It can be seen that as the treatment liquid in the treatment chamber continues to increase, when the moving cylinder 202 moves upward, the reacted treatment liquid and the treated gas will be discharged from the discharge pipe 802 to avoid safety hazards caused by gas-liquid accumulation. At the same time, the reacted treatment liquid is collected by the collection box 801, and the treated gas will be discharged through filtration of the activated carbon plate 803.

[0036] Furthermore, in order to cut the waste batteries more efficiently, the shredding assembly includes a rotating shaft 501 arranged at the center of the inner cylinder 103, the rotating shaft 501 is rotatably connected to the top of the frame 101, and a variable diameter spiral cutter 502 is fixedly connected to the outer wall of the rotating shaft 501. The diameter of the variable diameter spiral cutter 502 gradually increases from top to bottom, and a fixed cutter 503 that cooperates with the variable diameter spiral cutter 502 is fixedly connected to the inner wall of the inner cylinder 103. The dumping assembly includes a base 601 symmetrically fixed to the bottom of the frame 101, and a moving block 602 is slidably connected to the base 601. The moving block 602 is driven to slide by a driving member. The driving member can be specifically 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. The disc 603 A torsion spring is provided between the movable block 602, a top rod 605 that cooperates with the disc 603 is fixedly connected between the two bases 601, and the top surface of the disc 603 is rotatably connected to the raising platform 606, and a clamping block 611 is circumferentially provided on the side wall of the raising platform 606, and the clamping block 611 is slidably connected to the side wall of the raising platform 606. A second elastic member 612 is provided between the clamping block 611 and the raising platform 606, and the second elastic member 612 is specifically a spring. A clamping groove 1061 that cooperates with the clamping block 611 is provided at the bottom of the centrifugal cylinder 106, and the upper and lower side surfaces of the clamping block 611 are provided with inclined surfaces, so that the clamping block 611 can be smoothly inserted into the clamping groove 1061. A cross block 613 is fixedly connected to the top surface of the raising platform 606, and a groove 5011 that cooperates with the cross block 613 is provided on the bottom surface of the rotating shaft 501;

[0037] It can be seen that the cylinder cover 104 is opened, a certain amount of scrapped lithium batteries are put into the device from the feed port 1031, and then the cylinder cover 104 is closed, and then the drive motor 305 is started, and the drive motor 305 drives the centrifugal cylinder 106 to rotate, and then the centrifugal cylinder 106 drives the raising platform 606 to rotate through the connection relationship of the clamping block 611, and the raising platform 606 drives the rotating shaft 501 to rotate through the connection relationship of the cross block 613, and then the variable diameter spiral cutter 502 rotates, and the variable diameter spiral cutter 502 cooperates with the fixed cutter 503 to cut the waste batteries into pieces. The used batteries fall onto the top surface of the raised platform 606 and are centrifuged in conjunction with the rotation of the centrifuge cylinder 106. After the centrifugation is completed, the device stops, and then the electrolyte in the centrifuge cylinder 106 is taken out. After the electrolyte is taken out, the driving member is started again to move the disc 603 downward. When the disc 603 moves downward, it drives the raised platform 606 and the battery debris on the raised platform 606 to move downward together. As the disc 603 moves downward, the push rod 605 will push up one side of the disc 603, thereby causing the disc 603 to fall over, causing the torsion spring to store elastic potential energy. Figure 10As shown, the battery debris on the raising platform 606 slides off the raising platform 606 under the action of gravity. In this way, an additional collection box can be placed to collect the battery debris. After the processing is completed, the driving part is started again to move the disc 603 upward, and the torsion spring drives the disc 603 to reset, and the block 611 is re-engaged in the slot 1061, and the cross block 613 can also be engaged in the groove 5011. It should be added that while the disc 603 is tilting, a cleaning device can be used to clean the raising platform 606. On the one hand, it prevents debris from accumulating on the raising platform 606, and on the other hand, it prevents debris from being stuck in the cross block 613 and affecting the rotating shaft 501.
