Description

Technical Field

[0001] This invention belongs to the field of battery manufacturing technology, specifically relating to a graphite liquid circulation filtration device. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes to generate an electric current. It is a cup, tank, or other container or composite container. It has a positive electrode and a negative electrode, with the negative electrode being a crucial component of the battery.

[0003] In the process of processing battery negative electrode sheets, the negative electrode sheets need to be cleaned. The cleaning process is mostly carried out in a cleaning tank, where a chemical solution is used to clean the negative electrode sheets. However, most negative electrode sheets are made of graphite. During the cleaning process, the graphite on the negative electrode sheets flows away with the chemical solution. If the graphite content in the chemical solution is too high, the solution cannot effectively clean the negative electrode sheets. Therefore, the chemical solution needs to be replaced regularly, resulting in a large demand for the solution. The large amount of chemical solution required for the cleaning step leads to high production costs. Therefore, this application proposes a graphite chemical solution circulation filtration device. Summary of the Invention

[0004] The purpose of this invention is to provide a graphite liquid circulation filtration device to solve the problem mentioned in the background art that during the cleaning of the negative electrode sheet by the liquid, the graphite on the negative electrode sheet will flow away with the liquid. If the graphite content in the liquid is too high, the liquid will no longer be able to clean the negative electrode sheet. Therefore, the liquid needs to be replaced regularly, resulting in a large demand for liquid and high production costs due to the large amount of liquid required for the cleaning step.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a graphite liquid circulation filtration device, comprising a storage cylinder, wherein a connected inlet pipe is provided at the storage cylinder; The medicine storage cylinder is equipped with a lid and a filter canister installed on the medicine storage cylinder. The filter tank is provided with a flow divider that communicates with the medicine storage cylinder, and the flow divider is provided with a flow divider hole. The filter tank is provided with a connecting frame installed on the tank cover and a filter element connected to the connecting frame, and the filter element is provided with filter holes. The filter tank is provided with a mounting base, a lifting frame connected to the mounting base, a drive unit installed on the lifting frame, and a cleaning component connected to the drive unit. A return pipe is inserted into the bottom of the filter tank. The medicine storage cylinder is equipped with a filter platform for installing the filter tank and a lifting unit connected to the filter platform.

[0006] Preferably, the top of the medicine storage cylinder is provided with a detachable cylinder cover, and the cylinder cover is provided with two parallel handles, the handles being provided with anti-slip textures.

[0007] Preferably, a sealing ring is provided on the lower end face of the can lid, and a sealing gasket is wrapped around the bottom of the sealing ring. A sealing groove that mates with the sealing ring is provided inside the filter can.

[0008] Preferably, a positioning mechanism is provided at the can lid, the positioning mechanism including an upper insert block installed at the can lid and a lower insert block installed on the filter can, the upper insert block and the lower insert block being inserted into each other.

[0009] Preferably, the diversion orifice is vertically downward.

[0010] Preferably, a protective sleeve is provided between the lifting frame and the diverter, the protective sleeve being a rubber sleeve with a cavity inside.

[0011] Preferably, the filter tank is provided with a graphite discharge pipe, which includes a graphite detachment zone and a graphite discharge hole. When the tank cover is on the filter tank, the height of the graphite detachment zone is higher than the height of the filter element. When the cleaning element reaches the position of the filter element, the height of the lowest point of the graphite detachment zone is lower than the height of the filter element.

[0012] Preferably, the filter platform is provided with a graphite collection box aligned with the graphite discharge hole.

[0013] Preferably, the filter element has a downwardly recessed groove at the middle position, and the filter holes are located in the groove.

[0014] Preferably, the bottom of the filter platform is provided with a base plate, the lifting unit is installed on the base plate, and guide sleeves and guide rods that slide with the guide sleeves are inserted at the four corners of the filter platform. The bottom of the guide rods is provided with a base, and the base is installed on the base plate.

[0015] Beneficial effects: I. The graphite liquid circulation filtration device provided by the present invention has a cleaning tank containing a liquid medicine. The liquid medicine is used to clean the negative electrode sheet of the battery that enters the cleaning tank. Some of the negative electrode sheets of the battery are made of graphite material. After the liquid medicine cleans the negative electrode sheet, it will form a liquid medicine doped with graphite (hereinafter referred to as graphite liquid medicine). This graphite liquid medicine enters the storage cylinder through the medicine inlet pipe. When the lid is placed on the filter tank, the graphite solution in the storage cylinder enters the distribution component and falls onto the filter element through the distribution holes. The graphite in the solution is intercepted by the filter element on its upper side. The top of the filter element has a downward-facing recessed groove. This downward-facing groove gathers the graphite on the upper side of the filter element, causing it to accumulate in the middle of the filter element. The distribution holes in the distribution component are located at a certain distance from the center line. This ensures that the graphite gathered in the middle of the filter element does not obstruct the subsequent filtration of the graphite solution. The filtered solution enters the bottom of the filter tank and is sent to the cleaning tank through the return pipe, realizing the recycling of the solution, reducing the amount of solution input, and lowering the cost of solution consumption.

[0016] II. The graphite liquid circulation filtration device provided by this invention has a cleaning tank that stores liquid medicine. When a large amount of graphite accumulates on the filter element, the input of graphite liquid medicine is stopped, the lifting unit is activated, and the height of the filter tank is adjusted. The mounting base and lifting frame in the filter tank move synchronously with the filter tank, while the tank cover, the connecting frame installed on the tank cover, and the filter element do not move. In this way, the filter element and the cleaning element move closer to each other. Finally, when the cleaning element reaches the position of the filter element, the drive unit is activated, which can drive the cleaning element and the cleaning brush on it to rotate. The centrifugal force generated by the rotation of the cleaning element will push the graphite to the side away from the center line of the filter element. Finally, the graphite enters the graphite collection box through the graphite separation zone and the graphite discharge hole, thus realizing the collection of graphite and facilitating the subsequent recycling and processing of graphite. Furthermore, regular cleaning of the filter element by components such as the cleaning device can prevent graphite from accumulating on the filter element and ensure the filter element's filtration performance for graphite-based pharmaceutical solutions.

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figures 1-7 As shown in the figure, the graphite liquid circulation filtration device provided in this embodiment of the invention includes a storage cylinder 1, which is fixed by an external bracket installed on the wall of the factory roof. Specifically, the top of the storage cylinder 1 is provided with a detachable cylinder cover 2, and the cylinder cover 2 is provided with two parallel handles 3, which are provided with anti-slip textures.

[0021] It should be noted that a connected inlet pipe 4 is provided at the drug storage cylinder 1, and the cleaning pool contains a liquid medicine. The liquid medicine is used to clean the negative electrode sheet of the battery that enters the cleaning pool. Some batteries use graphite material for their negative electrode sheet. After cleaning the negative electrode sheet, the liquid medicine will form a liquid medicine mixed with graphite (hereinafter referred to as graphite liquid medicine). This graphite liquid medicine can only enter the inside of the drug storage cylinder 1 through the inlet pipe 4.

[0022] In order to filter out the graphite in the graphite medicine solution and send the filtered medicine solution back into the cleaning tank, a tank cover 5 and a filter tank 6 are installed on the medicine storage tank 1.

[0023] After the lid 5 is placed on the filter tank 6, a filter chamber is formed, and the graphite medicine is filtered inside the filter chamber. In order to increase the tightness of the connection between the lid 5 and the filter tank 6, a sealing ring 501 is provided on the lower end face of the lid 5. The bottom of the sealing ring 501 is wrapped with a sealing gasket 502. A sealing groove 601 that cooperates with the sealing ring 501 is provided inside the filter tank 6.

[0024] In order to align the can lid 5 with the filter can 6, a positioning mechanism 7 is provided at the can lid 5. The positioning mechanism 7 includes an upper insert block 701 installed at the can lid 5 and a lower insert block 702 installed on the filter can 6. The upper insert block 701 and the lower insert block 702 are inserted into each other.

[0025] To prevent the graphite solution from falling directly onto the cleaning component 13, a diversion component 8 connected to the storage cylinder 1 is provided inside the filter tank 6. The diversion component 8 is provided with a diversion hole 801, which is vertically downward.

[0026] Specifically, the filter tank 6 is provided with a connecting bracket 9 installed on the tank cover 5 and a filter element 10 connected to the connecting bracket 9. The filter element 10 is provided with filter holes, and a groove recessed downwards is provided in the middle of the filter element 10. The filter holes are located in the groove.

[0027] More specifically, the filter tank 6 is provided with a mounting base 11, a lifting frame 12 connected to the mounting base 11, a drive unit 14 mounted on the lifting frame 12, and a cleaning component 13 connected to the drive unit 14. The mounting base 11 and the filter component 10 are engaged and locked together.

[0028] When the lid 5 is placed on the filter tank 6, the graphite liquid in the storage cylinder 1 enters the diverter 8 and falls onto the filter element 10 through the diverter hole 801. The graphite in the liquid is intercepted on the upper side of the filter element 10. The top of the filter element 10 has a downward-facing recessed groove. The downward-facing groove can gather the graphite on the upper side of the filter element 10 and allow it to accumulate in the middle of the filter element 10. The diverter hole 801 in the diverter 8 is located at a certain distance from the center line. In this way, the graphite gathered in the middle of the filter element 10 will not hinder the subsequent filtration of the graphite liquid. The filtered liquid enters the bottom of the filter tank 6 and is sent to the cleaning tank through the return pipe 23, realizing the recycling of the liquid, reducing the amount of liquid input, and reducing the cost of liquid consumption.

[0029] Specifically, the drive unit 14 can be a servo motor. The bottom of the cleaning component 13 is equipped with a cleaning brush. The bottom of the cleaning component 13 has the same shape as the groove in the filter component 10. When a lot of graphite accumulates on the filter component 10, the input of graphite solution is stopped, the lifting unit 19 is started, and the height of the filter tank 6 is adjusted. The mounting base 11 and the lifting frame 12 in the filter tank 6 move synchronously with the filter tank 6, while the tank cover 5, the connecting frame 9 installed on the tank cover 5, and the filter component 10 do not move. In this way, the filter component 10 and the cleaning component 13 approach each other. Finally, when the cleaning component 13 reaches the position of the filter component 10, the drive unit 14 is started, which can drive the cleaning component 13 and the cleaning brush on it to rotate. The centrifugal force generated by the rotation of the cleaning component 13 will push the graphite to the side away from the center line of the filter component 10. Finally, the graphite enters the graphite collection box 17 through the graphite separation zone 1601 and the graphite discharge hole 1602. In this way, the graphite collection work is realized, which facilitates the subsequent recycling and processing of graphite. Furthermore, by regularly cleaning the filter element 10 through components such as the cleaning component 13, graphite can be prevented from accumulating on the filter element 10, thus ensuring the filtration performance of the filter element 10 for graphite liquid.

[0030] It should be noted that a return pipe 23 is inserted at the bottom of the filter tank 6.

[0031] Specifically, a protective sleeve 15 is provided between the lifting frame 12 and the diverter 8. The protective sleeve 15 is made of rubber and has a cavity inside. When the lifting frame 12 is raised, the protective sleeve 15 is disengaged from the diverter 8 first. The protective sleeve 15 is made of rubber and has a cavity inside. When the rubber sleeve is squeezed, it will squeeze the air inside, reducing the cavity size, thereby avoiding a hard collision between the lifting frame 12 and the diverter 8.

[0032] For details, please refer to Figure 5 A graphite discharge pipe 16 is provided at the filter tank 6. The graphite discharge pipe 16 includes a graphite detachment zone 1601 and a graphite discharge hole 1602. When the tank cover 5 is on the filter tank 6, the height of the graphite detachment zone 1601 is higher than the height of the filter element 10. When the cleaning element 13 reaches the position of the filter element 10, the height of the lowest point of the graphite detachment zone 1601 is lower than the height of the filter element 10.

[0033] When the cleaning component 13 reaches the position of the filter component 10, the height of the lowest point of the graphite separation zone 1601 is lower than the height of the filter component 10. At this time, the drive unit 14 is turned on, and the rotating filter component 10 can push the graphite away from the middle position of the filter component 10, so that the graphite enters the graphite separation zone 1601 and enters the graphite discharge hole 1602 through the graphite discharge pipe 16. The graphite enters the graphite collection box 17 from the graphite discharge hole 1602, realizing the collection of graphite.

[0034] In order to achieve the combination and separation between the filter tank 6 and the tank cover 5, a filter platform 18 for installing the filter tank 6 and a lifting unit 19 connected to the filter platform 18 are provided at the medicine storage cylinder 1. The lifting unit 19 can be an electric telescopic rod. A graphite collection box 17 aligned with the graphite discharge hole 1602 is provided at the filter platform 18.

[0035] In order to guide the movement of the filter platform 18, a base plate is provided at the bottom of the filter platform 18, the lifting unit 19 is installed on the base plate, and guide sleeves 21 and guide rods 20 that slide with the guide sleeves 21 are inserted at the four corners of the filter platform 18. A base 22 is provided at the bottom of the guide rods 20 and the base 22 is installed on the base plate.

[0036] In summary: This invention provides a graphite liquid filtration device. The cleaning tank contains a liquid that is used to clean the negative electrode of the battery that enters the cleaning tank. Some of the negative electrode of the battery is made of graphite material. After cleaning the negative electrode, the liquid will form a graphite-doped liquid (hereinafter referred to as graphite liquid). This graphite liquid enters the storage cylinder 1 only through the inlet pipe 4. When the lid 5 is placed on the filter tank 6, the graphite liquid in the storage cylinder 1 enters the diverter 8 and falls onto the filter element 10 through the diverter hole 801. The graphite in the liquid is intercepted on the upper side of the filter element 10. The top of the filter element 10 has a downward-facing recessed groove. The downward-facing groove can gather the graphite on the upper side of the filter element 10 and allow it to accumulate in the middle of the filter element 10. The diverter hole 801 in the diverter 8 is located at a certain distance from the center line. In this way, the graphite gathered in the middle of the filter element 10 will not hinder the subsequent filtration of the graphite liquid. The filtered liquid enters the bottom of the filter tank 6 and is sent to the cleaning tank through the return pipe 23, realizing the recycling of the liquid, reducing the amount of liquid input, and reducing the cost of liquid consumption.

[0037] When a large amount of graphite accumulates on the filter element 10, the input of graphite solution is stopped, the lifting unit 19 is activated, and the height of the filter tank 6 is adjusted. The mounting base 11 and the lifting frame 12 in the filter tank 6 move synchronously with the filter tank 6, while the tank cover 5, the connecting frame 9 installed on the tank cover 5, and the filter element 10 do not move. In this way, the filter element 10 and the cleaning element 13 approach each other. Finally, the cleaning element 13 reaches the position where the filter element 10 is located, and the drive unit 14 is activated, which can drive the cleaning element 13 and the cleaning brush on it to rotate. The centrifugal force generated by the rotation of the cleaning element 13 will push the graphite to the side away from the center line of the filter element 10. Finally, the graphite enters the graphite collection box 17 through the graphite separation zone 1601 and the graphite discharge hole 1602. In this way, the graphite collection work is realized, which facilitates the subsequent recycling and processing of graphite. Furthermore, by regularly cleaning the filter element 10 through components such as the cleaning component 13, graphite can be prevented from accumulating on the filter element 10, thus ensuring the filtration performance of the filter element 10 for graphite liquid.

[0038] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
