Description

Technical Field

[0001] This invention relates to the field of filtration technology, specifically to a high-sulfur environmental purification device for graphitized lithium-ion battery negative electrodes. Background Technology

[0002] High-sulfur graphitization of lithium-ion battery anodes refers to the treatment used to remove sulfur-containing impurities from graphite powder produced during lithium-ion battery manufacturing. Graphite is one of the main materials for the anode in lithium-ion battery manufacturing, and the sulfur content in graphite powder can affect battery performance and safety. Chemical reagents are added to purify and dissolve the sulfur, which is then removed through filtration.

[0003] In existing technologies, solid sulfide particles generally cannot be effectively removed directly by activated carbon filtration. Solid sulfide particles are usually quite large and may clog the pores of activated carbon during the filtration process, resulting in poor purification performance and affecting the purification effect of lithium batteries. Therefore, a graphitized high-sulfur environmentally friendly purification device for lithium battery anodes is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a graphitized high-sulfur environmentally friendly purification device for lithium-ion battery anodes, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-sulfur environmentally friendly purification device for graphitized lithium-ion battery anodes, comprising a purification tank, a support column fixedly connected to the bottom of the purification tank, an activated carbon filter box fixedly penetrating the side of the purification tank, and an adaptive activated carbon filter device installed inside the purification tank; the adaptive filter assembly includes a motor, the side of the motor fixedly connected to the inner side of the purification tank, a reciprocating lead screw fixedly connected to the output shaft of the motor, a threaded sleeve threadedly connected to the circumferential surface of the reciprocating lead screw, a contact rod fixedly connected to the circumferential surface of the threaded sleeve, a rotating shaft rotatably connected to the side of the activated carbon filter box, and a filter plate rotatably connected to the circumferential surface of the rotating shaft; the adaptive filter assembly is designed primarily to filter out sulfur impurities that have been separated by chemical reagents inside the purification tank, thereby filtering out sulfur substances from the surface of the lithium-ion battery inside the purification tank after purification, thus improving the purification effect.

[0006] The activated carbon exchange assembly includes an L-shaped straight channel, one end of which is located on the inner side of the purification tank. An arc-shaped hydraulic cylinder is fixedly connected inside the L-shaped straight channel. A hydraulic rod and a push rod pass through both ends of the arc-shaped hydraulic cylinder, respectively. A connecting rod is fixedly connected to one end of the hydraulic rod, and the other end of the connecting rod is fixedly connected to the circumferential surface of a threaded sleeve. An activated carbon storage box is fixedly connected to the top of the purification tank. A carbon outlet is located at the bottom of the activated carbon storage box. A baffle is slidably connected between the carbon outlet and the purification tank. The side of the baffle is fixedly connected to one end of the push rod. A carbon filling port is located at the top of the activated carbon filter box. The design of the activated carbon exchange assembly is mainly to simultaneously fill the activated carbon inside the activated carbon filter box during the rotation of the filter plate, ensuring the freshness of the activated carbon filter box during each filtration and impurity removal process. Furthermore, the filling process is manual and easy to operate.

[0007] According to the above technical solution, a force-bearing rod is rotatably connected to the circumference of the rotating shaft. One end of the force-bearing rod is located on the displacement trajectory of the contact rod. During displacement, the contact rod applies a compressive force to the force-bearing rod, driving the rotating shaft to rotate. A square groove is provided on the side of the activated carbon filter box, so that the force-bearing rod is not obstructed by one side of the activated carbon filter box during rotation, ensuring the stable operation of the device. A torsion spring is fixedly connected to the circumference of the rotating shaft. One end of the torsion spring is fixedly connected to the top of the activated carbon filter box. The main function of the torsion spring is to drive the rotating shaft to rotate through its torsion force when the force-bearing rod is not subjected to compressive force. An inclined plate is fixedly connected to the bottom of the inner wall of the purification tank. The design of the inclined plate allows the lithium batteries inside the purification tank to be better displaced and concentrated at the discharge port, facilitating material discharge.

[0008] According to the above technical solution, the top of the purification tank is provided with a notch, and the carbon outlet, carbon inlet, and notch are interconnected. A movable opening is provided on the inner side of the purification tank, and a return spring is fixedly connected inside the movable opening. One end of the return spring is fixedly connected to the side of the baffle. The interconnection of the carbon outlet, carbon inlet, and notch ensures that the activated carbon inside the activated carbon storage box is accurately filled into the activated carbon filter box during the automatic filling process. The function of the return spring is mainly to automatically reset and close the carbon inlet when the baffle is not subjected to the squeezing force of the hydraulic rod, utilizing its elasticity.

[0009] According to the above technical solution, the purification tank is equipped with a discharge device, which includes a rectangular trough. One end of the rectangular trough is located on the inner side of the purification tank. A telescopic rod is slidably connected inside the rectangular trough. A straight rod is fixedly connected to the telescopic end of the telescopic rod, and a combined control panel is fixedly connected to the other end of the telescopic rod. The top of the straight rod is fixedly connected to the bottom of the connecting rod. A discharge plate is fixedly connected to the side of the combined control panel, and a discharge port is provided at the bottom of the purification tank. The design of the discharge device is mainly to automatically discharge the purified and filtered lithium batteries inside the purification tank, thereby facilitating the recycling of the processed lithium batteries by staff.

[0010] According to the above technical solution, a receiving box is slidably connected to the bottom of the purification tank, and the top of the receiving box is located directly below the discharge port. The design of the receiving box enables automatic discharge of the purified lithium batteries from the purification tank, facilitating collection by staff.

[0011] According to the above technical solution, the bottom of the discharge plate is slidably connected to the top of the inclined plate, and the size of the discharge plate is larger than the diameter of the discharge port. The slidable connection of the bottom of the discharge plate to the top of the inclined plate increases the stability of the discharge plate during displacement, while the larger size of the discharge plate allows for better blocking of one end of the discharge port during the purification and desulfurization process.

[0012] According to the above technical solution, the activated carbon filter box is equipped with an activated carbon leveling device. The activated carbon leveling device includes a fixing plate, the top of which is fixedly connected to the top of the inner wall of the activated carbon filter box. A connecting shaft extends through the side of the fixing plate, and a force-bearing disc is fixedly sleeved on the circumference of the connecting shaft. A small gear is fixedly connected to one end of the connecting shaft. A rack plate is slidably connected to the inner side of the activated carbon filter box, and a leveling rod is fixedly connected to one side of the rack plate. The activated carbon leveling device is designed primarily to automatically level the activated carbon after it is added to the activated carbon filter box, increasing the filtration area of ​​the activated carbon inside the filter box and thus improving the filtration effect of the activated carbon inside the filter box.

[0013] According to the above technical solution, a hollow protective box is fixedly connected to the inner side of the activated carbon filter box. The end of the connecting shaft near the pinion passes through one side of the hollow protective box, the pinion is located inside the hollow protective box, and the rack plate passes through the side of the hollow protective box. The hollow protective box is designed as a hollow cuboid mainly to prevent the activated carbon in the activated carbon filter box from directly contacting the meshing point of the pinion and the rack plate during displacement, thus preventing the pinion and the rack plate from jamming during meshing.

[0014] According to the above technical solution, a guide plate is fixedly connected inside the char outlet, and the gap between the guide plate and the char outlet is located directly above the force-receiving plate. The guide plate is designed so that, through its inclined surface, the activated carbon can always fall accurately onto the force-receiving plate through the gap between the guide plate and the char outlet during its descent, thereby driving the force-receiving plate to rotate.

[0015] According to the above technical solution, multiple baffles are fixedly connected to the circumferential surface of the force-receiving disk, and the multiple baffles are arranged in a circumferential array on the circumferential surface of the force-receiving disk. The design of the baffles is mainly to increase the contact area between the force-receiving disk and the activated carbon, so that the activated carbon can better drive the force-receiving disk to rotate during the falling process.

[0016] This invention provides a high-sulfur environmentally friendly purification device for graphitized lithium-ion battery anodes. It has the following beneficial effects: (1) The present invention uses the adaptive filter component and activated carbon quantity exchange component inside the adaptive activated carbon filter device to make the force rod on the circumference of the rotating shaft rotate, thereby driving the rotating shaft to rotate, and then driving the filter plate to rotate, opening the activated carbon filter hole box to adsorb sulfur impurities inside the purification tank, removing sulfur impurities inside the purification tank. At the same time, the baffle will move into the through groove opened on the inner side of the purification tank during the displacement process. At this time, the carbon inlet opens, and the carbon outlet, carbon inlet and notch are connected to each other. The activated carbon inside the carbon outlet is automatically fed into the activated carbon filter hole box due to gravity and without being blocked by the baffle. This achieves the effect of filtering the sulfur impurities that have been separated by chemical reagents inside the purification tank, so that the sulfur substances on the surface of the lithium battery inside the purification tank are filtered after purification, improving the purification effect. At the same time, the activated carbon inside the activated carbon filter hole box is filled, ensuring the freshness of the activated carbon filter hole box during each filtration and impurity removal process. Moreover, no manual operation is required during the filling process, making the operation convenient.

[0017] (2) By configuring the internal components such as the telescopic rod and the discharge plate of the discharge device, the present invention enables the control board to drive the discharge plate to move from left to right. The discharge plate moves from left to right to open the discharge port. At this time, the lithium battery inside the purification tank has moved to the top of the discharge port due to the inclined surface design of the inclined plate, and then falls into the receiving box for recycling. This achieves the automatic discharge of the purified and filtered lithium battery inside the purification tank, which makes it easier for staff to recycle the processed lithium battery.

[0018] (3) By setting up components such as the force-receiving plate and rack plate inside the activated carbon leveling device, the activated carbon falls into the activated carbon filter box and drives the force-receiving plate to rotate. The rotation of the force-receiving plate drives the connecting shaft to rotate, the rotation of the connecting shaft drives the pinion to rotate, and the rotation of the pinion drives the rack plate to move horizontally inside the activated carbon filter box. This, in turn, drives the leveling rod to move horizontally inside the activated carbon filter box, thus achieving the effect of automatically leveling the activated carbon after it is added to the activated carbon filter box, increasing the filtration area of ​​the activated carbon inside the activated carbon filter box, and thus improving the filtration effect of the activated carbon inside the activated carbon filter box.

[0021] 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.

[0022] Please see Figure 1-7 An embodiment of the present invention is as follows: a high-sulfur environmental protection purification device for graphitized lithium battery negative electrode includes a purification pool 1, a support column 2 is fixedly connected to the bottom of the purification pool 1, an activated carbon filter box 3 is fixedly passed through the side of the purification pool 1, and an adaptive activated carbon filter device 4 is provided inside the purification pool 1. The adaptive activated carbon filtration device 4 includes an adaptive filtration component 40 and an activated carbon metering component 41. The adaptive filtration component 40 includes a motor 401, which is fixedly connected to the inner side of the purification tank 1. The output shaft of the motor 401 is fixedly connected to a reciprocating lead screw 402. A threaded sleeve 403 is threadedly connected to the circumferential surface of the reciprocating lead screw 402. A contact rod 404 is fixedly connected to the circumferential surface of the threaded sleeve 403. A rotating shaft 405 is rotatably connected to the side of the activated carbon filter box 3. A filter plate 406 is rotatably connected to the circumferential surface of the rotating shaft 405. The adaptive filtration component 40 is designed to filter out sulfur impurities that have been separated by chemical reagents inside the purification tank 1, so that after the lithium battery inside the purification tank 1 is purified, the sulfur substances on its surface are filtered out, thereby improving the purification effect.

[0023] The activated carbon exchange assembly 41 includes an L-shaped straight groove 411, one end of which is located on the inner side of the purification tank 1. An arc-shaped hydraulic cylinder 412 is fixedly connected inside the L-shaped straight groove 411. A hydraulic rod 413 and a push rod 420 pass through both ends of the arc-shaped hydraulic cylinder 412, respectively. A connecting rod 414 is fixedly connected to one end of the hydraulic rod 413. One end of the connecting rod 414 is fixedly connected to the circumferential surface of the threaded sleeve 403. An activated carbon storage box 415 is fixedly connected to the top of the purification tank 1. A carbon outlet 416 is provided at the bottom of the activated carbon storage box 415. A baffle 417 is slidably connected between the carbon outlet 416 and the purification tank 1. The side of the baffle 417 is fixedly connected to one end of the push rod 420. A carbon addition port 418 is provided at the top of the activated carbon filter box 3. The activated carbon exchange component 41 is designed to work with the filter plate 406 to simultaneously fill the activated carbon inside the activated carbon filter box 3 during the rotation process, ensuring the freshness of the activated carbon filter box 3 during each filtration and impurity removal process. Moreover, the filling process does not require manual operation and is convenient to operate.

[0024] A force-bearing rod 407 is rotatably connected to the circumference of the rotating shaft 405. One end of the force-bearing rod 407 is located on the displacement trajectory of the contact rod 404. During displacement, the contact rod 404 applies a compressive force to the force-bearing rod 407, causing the rotating shaft 405 to rotate. A square groove is provided on the side of the activated carbon filter box 3, so that the force-bearing rod 407 is not obstructed by one side of the activated carbon filter box 3 during rotation, ensuring the stable operation of the device. A torsion spring 408 is fixedly connected to the circumference of the rotating shaft 405. One end of the torsion spring 408 is fixedly connected to the top of the activated carbon filter box 3. The main function of the torsion spring 408 is to drive the rotating shaft 405 to rotate through its torsion force when the force-bearing rod 407 is not subjected to compressive force. An inclined plate 409 is fixedly connected to the bottom of the inner wall of the purification tank 1. The design of the inclined plate 409 allows the lithium batteries inside the purification tank 1 to be better displaced and concentrated at the discharge port 56, facilitating material discharge.

[0025] The top of the purification tank 1 has an opening, and the carbon outlet 416, carbon inlet 418, and the opening are interconnected. An movable opening is provided on the inner side of the purification tank 1, and a return spring 419 is fixedly connected inside the movable opening. One end of the return spring 419 is fixedly connected to the side of the baffle 417. The interconnection of the carbon outlet 416, carbon inlet 418, and the opening ensures that the activated carbon inside the activated carbon storage box 415 is accurately filled into the activated carbon filter box 3 during the automatic filling process. The function of the return spring 419 is mainly to automatically reset and close the carbon inlet 418 when the baffle 417 is not subjected to the squeezing force of the hydraulic rod 413, utilizing its elasticity.

[0026] In use, the activated carbon filter box 3 is designed as a hollow cuboid with several filter holes smaller than the diameter of the activated carbon on both sides. After the purification liquid inside the purification tank 1 purifies the sulfides on the lithium battery, the purification liquid containing sulfides remains inside the purification tank 1. At this time, the operator can start the motor 401 to drive the reciprocating screw 402 to rotate. The rotation of the reciprocating screw 402 drives the threaded sleeve 403 to move horizontally, which in turn drives the contact rod 45 to move horizontally. When the contact rod 45 moves to the force rod 407, because the side of the rotating shaft 405 is rotatably connected to the side of the activated carbon filter box 3, it will drive the force rod 407 fixed on the circumference of the rotating shaft 405 to rotate, thereby driving the rotating shaft 405 to rotate. 05 rotates, which in turn drives the filter plate 406 to rotate, opening the activated carbon filter box 3. The sulfide-containing purification liquid inside the purification tank enters the interior of the activated carbon filter box 3 through the filter holes set on the side of the activated carbon filter box 3, adsorbing the sulfur impurities in the purification liquid and removing the sulfur impurities contained in the purification tank and purification liquid. At this time, the staff only needs to wait on the other side of the activated carbon filter box 3 to collect the filtered purification liquid, and at the same time turn off the motor 401. After filtration is completed, the motor 401 is restarted, and the threaded sleeve 403 drives the contact rod 404 to move in the opposite direction. The force rod 407 is no longer subjected to the squeezing force of the contact rod 404. Due to the torsion of the torsion spring 408, the filter plate 406 automatically rebounds and closes the activated carbon filter box 3. The adaptive filtration component 40 is designed mainly to filter the sulfur impurities that have been separated by chemical reagents inside the purification tank 1, so that after the lithium battery inside the purification tank 1 is purified, the sulfur substances on its surface are filtered out, improving the purification effect. Simultaneously, during the displacement of the threaded sleeve 403, it drives the connecting rod 414 to move horizontally, thereby driving the hydraulic rod 413 to move horizontally and compress one end of the arc-shaped hydraulic cylinder 412. After being compressed, the arc-shaped hydraulic cylinder 412 transmits the compressive force to the other end through the internal piston, which is connected to the sliding push rod 420. This push rod 420 is then moved horizontally. During the displacement, the push rod 420 drives the baffle 417 to move. During this displacement, the baffle 417 moves to the inner side of the purification tank 1. Inside the opened channel, the activated carbon stored in the activated carbon storage box 415, which is inverted at the top of the purification tank 1, will be blocked at the carbon outlet 416 due to gravity. Since the carbon inlet 418 is open, the carbon outlet 416, carbon inlet 418, and the notch are interconnected. The activated carbon inside the carbon outlet 416 automatically moves downwards due to gravity and is not obstructed by the baffle 417, filling the activated carbon filter box 3 through the carbon inlet 418. At this time, the filter plate 406 is in a filtration state after displacement. The activated carbon exchange component 41 is designed to work with the filter plate 406 to simultaneously fill the activated carbon inside the activated carbon filter box 3 during rotation, ensuring the freshness of the activated carbon filter box 3 during each filtration and impurity removal process. Moreover, the filling process is manual and easy to operate.

[0027] Please see Figure 1-7 Based on the above embodiments, in another embodiment of the present invention, a discharge device 5 is provided inside the purification tank 1. The discharge device 5 includes a rectangular trough 51, one end of which is opened on the inner side of the purification tank 1. A telescopic rod 52 is slidably connected inside the rectangular trough 51. A straight rod 53 is fixedly connected to the telescopic end of the telescopic rod 52. A combined control plate 54 is fixedly connected to the other end of the telescopic rod 52. The top of the straight rod 53 is fixedly connected to the bottom of the connecting rod 414. A discharge plate 55 is fixedly connected to the side of the combined control plate 54. A discharge port 56 is opened at the bottom of the purification tank 1. The design of the discharge device 5 is mainly to automatically discharge the purified and filtered lithium batteries inside the purification tank 1, thereby facilitating the recycling of the processed lithium batteries by the staff.

[0028] A receiving box 57 is slidably connected to the bottom of the purification tank 1, and the top of the receiving box 57 is located directly below the discharge port 56. The design of the receiving box 57 enables automatic discharge of the purified lithium batteries inside the purification tank 1, making it convenient for staff to collect them.

[0029] The bottom of the discharge plate 55 is slidably connected to the top of the inclined plate 409, and the size of the discharge plate 55 is larger than the diameter of the discharge port 56. The slidable connection of the bottom of the discharge plate 55 to the top of the inclined plate 409 increases the stability of the discharge plate 55 during displacement, and the larger size of the discharge plate 55 than the diameter of the discharge port 56 allows the discharge plate 55 to better block one end of the discharge port 56 during the purification and desulfurization process.

[0030] The activated carbon filter box 3 is equipped with an activated carbon leveling device 6. The activated carbon leveling device 6 includes a fixing plate 61, the top of which is fixedly connected to the top of the inner wall of the activated carbon filter box 3. A connecting shaft 62 passes through the side of the fixing plate 61. A force-receiving plate 63 is fixedly sleeved on the circumference of the connecting shaft 62. A small gear 64 is fixedly connected to one end of the connecting shaft 62. A rack plate 65 is slidably connected to the inner side of the activated carbon filter box 3, and a leveling rod 66 is fixedly connected to one side of the rack plate 65. The activated carbon leveling device 6 is designed primarily to automatically level the activated carbon after it is added to the activated carbon filter box 3, increasing the filtration area of ​​the activated carbon inside the activated carbon filter box 3, thereby improving the filtration effect of the activated carbon inside the activated carbon filter box 3.

[0031] A hollow protective box 67 is fixedly connected to the inner side of the activated carbon filter box 3. The end of the connecting shaft 62 near the pinion 64 passes through one side of the hollow protective box 67. The pinion 64 is located inside the hollow protective box 67, and the rack plate 65 passes through the side of the hollow protective box 67. The hollow protective box 67 is designed as a hollow cuboid, mainly to prevent the activated carbon in the activated carbon filter box 3 from directly contacting the meshing point of the pinion 64 and the rack plate 65 during displacement, thus preventing the pinion 64 and the rack plate 65 from jamming during meshing.

[0032] A guide plate 68 is fixedly connected inside the char outlet 416. The gap between the guide plate 68 and the char outlet 416 is located directly above the force-receiving plate 63. The guide plate 68 is designed so that, through its inclined design, the activated carbon can always fall accurately onto the force-receiving plate 63 through the gap between the guide plate 68 and the char outlet 416 during its descent, thereby driving the force-receiving plate 63 to rotate.

[0033] Multiple baffles are fixedly connected to the circumferential surface of the force-receiving disk 63, and the baffles are arranged in a circumferential array on the circumferential surface of the force-receiving disk 63. The design of the baffles is mainly to increase the contact area between the force-receiving disk 63 and the activated carbon, so that the activated carbon can better drive the force-receiving disk 63 to rotate during the falling process.

[0034] When in use, when the motor 401 is started for the first time, it drives the reciprocating screw 402 to rotate the threaded sleeve 403. The connecting rod 414 drives the straight rod 53 to move from right to left. The straight rod 53 drives the telescopic rod 52 to extend and retract, and slides from right to left inside the rectangular groove 51. The other end of the telescopic rod 52 drives the combined control plate 54 to move from right to left. The combined control plate 54 drives the discharge plate 55 to move from right to left. The discharge plate 55 moves from right to left to close the discharge port 56. At this time, the other end of the telescopic rod 52 touches the inner wall of the rectangular groove 51 and is blocked, so that the combined control plate 54 stops moving. Then the combined control plate 54 drives the discharge plate 55 to stop moving, which is the working state for filtering sulfides inside the purification tank 1. When the motor 401 is restarted for the second time, the motor 401 drives the reciprocating screw 402 to rotate the threaded sleeve 403. The connecting rod 414 drives the straight rod 53 to move from left to right. The straight rod 53 drives the telescopic rod 52 to extend and slide from left to right inside the rectangular groove 51. The other end of the telescopic rod 52 drives the combined control plate 54 to move from left to right. The combined control plate 54 drives the discharge plate 55 to move from left to right. The discharge plate 55 moves from left to right and opens the discharge port 56. At this time, the lithium battery inside the purification tank 1 has moved to the top of the discharge port 56 due to the inclined surface design of the inclined plate 409, and then falls into the receiving box 57 for recycling. This is the working state after filtration.

[0035] When activated carbon falls into the activated carbon filter box 3, it will cause the force-receiving plate 63 to rotate. The rotation of the force-receiving plate 63 will cause the connecting shaft 62 to rotate. The rotation of the connecting shaft 62 will cause the pinion 64 to rotate. The rotation of the pinion 64 will cause the rack plate 65 to move horizontally inside the activated carbon filter box 3, which in turn will cause the leveling rod 66 to move horizontally inside the activated carbon filter box 3, displacing the activated carbon to different areas inside the activated carbon filter box 3, expanding the filtration area of ​​the activated carbon. When the carbon inlet 418 is closed, the rack plate 65 will automatically spring back to its original position due to the elasticity of the spring designed on the back side, ensuring the next use.

[0036] The above description is only a preferred embodiment 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.
