Description

Technical Field

[0001] This invention belongs to the field of electrochemical water treatment technology, and particularly relates to a device and method for cleaning the positive electrode sheet of an electrochemical water treatment equipment. Background Technology

[0002] A positive electrode usually refers to a positive electrode with a high potential that contains active materials that undergo a reduction reaction during discharge. In lithium batteries, positive electrodes are usually made of materials such as lithium compounds and lithium cobalt oxide. During charging and discharging, lithium ions move back and forth between the two electrodes to complete the conversion and storage of electrical energy.

[0003] Positive electrode sheets are commonly used in electrochemical reactions, water electrolysis, electrodeposition, and other fields. After long-term use, a large amount of dirt and rust may indeed accumulate on the surface of the positive electrode sheet. These impurities not only affect the appearance of the positive electrode sheet, but may also affect its normal use and efficiency. Therefore, in order to ensure the normal use of the positive electrode sheet, it is indeed necessary to regularly remove impurities from its surface. Currently, most positive electrode sheets are cleaned and polished manually, which is time-consuming and extremely inefficient, and is not conducive to production. Summary of the Invention

Therefore, in order to ensure the normal use of the positive electrode, it is necessary to regularly remove impurities from the surface of the positive electrode. Currently, most positive electrode cleaning and polishing are done manually, which is time-consuming and extremely inefficient, and is not conducive to production.

[0010] Preferably, a water tank is provided on the top of the processing chamber, and a flexible tube is connected to the outside of the assembly frame by a limiting block. The flexible tube is connected to the water tank, and a spray head is connected to the end of the flexible tube away from the water tank.

[0012] Preferably, the bottom side of the discharge pipe is connected to a filter box, the filter box is equipped with a filter screen, and the bottom side of the filter box has a discharge port.

[0013] In a second aspect, a method for cleaning the positive electrode sheet of an electrochemical water treatment device is provided, employing the positive electrode sheet cleaning apparatus for an electrochemical water treatment device as described in the first aspect of the present invention. The method includes the following steps:

[0014] Place the positive electrode sheet to be processed onto the feeding assembly;

[0015] The two first motors drive the corresponding screws to rotate, thereby causing the connecting block to move the upper scraping assembly horizontally along the processing chamber, thereby adjusting the distance between the two scrapers and the positive electrode plate.

[0016] The motor drives the moving end of the lead screw slide to move the scraper longitudinally and horizontally, so that the inclined blade of the scraper can remove the side wall of the positive electrode during the reciprocating motion.

[0023] Compared with the prior art, the embodiments of this application have the following main advantages:

This improves cleaning efficiency while reducing the uncontrollability of human operation, thereby ensuring the cleanliness of the positive electrode sheet and improving its performance and service life.

[0025] Secondly, the purpose of setting the limiting groove on the cleaning table is to restrict the movement of the positive electrode sheet and ensure that its position is fixed during the processing. The function of the return spring is to keep the positive electrode sheet stable in the limiting groove. When the positive electrode sheet is placed in the limiting groove, the return spring will bounce it back to its original position to ensure the accurate position of the positive electrode sheet. Each of the return springs is equipped with a damper to slow down the rebound speed of the return spring, making the placement and removal of the positive electrode sheet more stable. In conjunction with the magnetic suction plate, it uses magnetic force to firmly attract the positive electrode sheet to its surface, ensuring the stability and accuracy of the positive electrode sheet during the processing.

[0026] Thirdly, by setting up spray heads on the side of the abrasive assembly, flexible pipes deliver water to the spray heads, and the spray heads spray water onto the positive electrode plate of the cleaning platform, thus achieving the effect of wetting and cooling the positive electrode plate.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order. The term "a number" in the specification and claims of this application refers to one or more objects being described.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0037] This invention provides a positive electrode cleaning device for electrochemical water treatment equipment, such as... Figure 1-7 As shown, the assembly includes a processing chamber 1, an adjustment component, a scraping component, a material feeding component, and an abrasive component. The adjustment component includes two assembly shells 201 located on the bottom side of the processing chamber 1, each housing a screw 202 connected to it via bearings. A first motor 203 is located on the outside of the two assembly shells 201, with its output ends fixedly connected to the ends of the corresponding screws 202 via keys. Each screw 202 has a threaded connecting block 204, which is connected to the assembly shell 201. The inner wall of the 1 slides together; the scraping assembly includes a first connecting plate 301 symmetrically arranged above two connecting blocks 204; a set of hydraulic rods 302 arranged above the two first connecting plates 301, the output ends of each pair of adjacent hydraulic rods 302 are connected to the same second connecting plate 303; a lead screw slide 304 arranged above the two second connecting plates 303, the moving ends of the two lead screw slides 304 are each connected to a scraper 305 for removing the side wall of the positive electrode plate, and the two scrapers 305 are inclined with their blades facing each other.

[0038] It should be noted that after long-term use, the surface of the positive electrode sheet may indeed accumulate a large amount of dirt and rust. These impurities not only affect the appearance of the positive electrode sheet but may also affect its normal use and efficiency. Therefore, in order to ensure the normal use of the positive electrode sheet, it is indeed necessary to perform regular impurity removal treatment on its surface. Currently, most positive electrode sheets are cleaned and polished manually, which is time-consuming and extremely inefficient, hindering production. This solution uses a combination of a scraping component and an abrasive component. The abrasive component can quickly remove dirt and rust from the surface of the positive electrode sheet through high-speed rotation, while the scraping device can remove impurities adhering to the surface of the positive electrode sheet. This improves cleaning efficiency while reducing the uncontrollability of manual operation, thereby ensuring the cleanliness of the positive electrode sheet and improving its performance and service life.

[0039] Specifically, in this embodiment, the solution mainly includes a processing chamber 1, an adjustment assembly, a scraping assembly, a material placement assembly, and an abrasive assembly. The adjustment assembly includes two assembly shells 201 located on the bottom side of the processing chamber 1, each of which has a screw 202 connected to it via a bearing. A first motor 203 is located on the outside of the two assembly shells 201, with the output ends of the two first motors 203 respectively fixedly connected to the ends of the corresponding screws 202. Each of the two screws 202 has a threaded connection to a connecting block 204, which slides against the inner wall of the assembly shell 201. The scraping assembly includes first connecting plates 301 symmetrically arranged above the two connecting blocks 204. A set of hydraulic rods 302 is located above the two first connecting plates 301, with the output ends of every two adjacent hydraulic rods 302 connected to the same... A second connecting plate 303; a lead screw slide 304 disposed above the two second connecting plates 303, each of the two lead screw slides 304 having a scraper 305 connected to its moving end for removing the sidewall of the positive electrode sheet, the two scrapers 305 being inclined with their blades facing each other; two first motors 203 respectively drive the screw 202 to rotate, because the connecting block 204 slides in cooperation with the inner wall of the assembly housing 201, the connecting block 204 can only drive the scraping component above to move horizontally along the processing chamber 1, thereby adjusting the distance between the two scrapers 305 and the positive electrode sheet, so as to perform cleaning activities on positive electrode sheets of different sizes; when the outer wall of the positive electrode sheet is polished, the motor of the lead screw slide 304 drives its moving end to move the scraper 305 longitudinally horizontally, and in the reciprocating motion, the inclined blade of the scraper 305 effectively scrapes away the sidewall of the positive electrode sheet during the movement.

[0040] In a further preferred embodiment of the present invention, such as Figure 1-2 As shown, the material placement assembly includes: a support base 401 located at the center of the bottom side of the processing chamber 1; a second motor 402 located inside the support base 401; and a cleaning table 403 located above the support table via a bearing, wherein the output end of the second motor 402 is fixedly connected to the end of the cleaning table 403.

[0041] In this embodiment, the second motor 402 is used to drive the cleaning table 403 to rotate, thereby realizing multi-angle cleaning of the positive electrode sheet and improving the comprehensiveness of the cleaning.

[0042] In a further preferred embodiment of the present invention, such as Figure 1-5 As shown, the material placement assembly further includes a magnetic suction plate 501; a limiting groove 502 for placing the positive electrode sheet is provided in the middle of the cleaning table 403, and a plurality of return springs 503 are provided on the inner walls of the limiting grooves 502 respectively. Each of the plurality of return springs 503 is provided with a damper, and the side of the plurality of return springs 503 away from the wall of the limiting groove 502 is respectively connected to the magnetic suction plate 501.

[0043] In this embodiment, the function of the limiting groove 502 is to restrict the movement of the positive electrode sheet and ensure that its position is fixed during the processing. The function of the return spring 503 is to keep the positive electrode sheet in the limiting groove 502 stable. When the positive electrode sheet is placed in the limiting groove 502, the return spring 503 will bounce it back to its original position to ensure the accurate position of the positive electrode sheet. Each of the return springs 503 is provided with a damper to slow down the rebound speed of the return spring 503, so that the placement and removal of the positive electrode sheet is more stable. In conjunction with the magnetic suction plate 501, it firmly attracts the positive electrode sheet to its surface through magnetic force, ensuring the stability and accuracy of the positive electrode sheet during the processing.

[0044] In a further preferred embodiment of the present invention, such as Figure 1-2 As shown, the abrasive assembly includes: hydraulic cylinders 601 symmetrically arranged on the top side of the processing chamber 1; and an assembly frame 602 located below the hydraulic cylinders 601, the assembly frame 602 slidingly engaging with the inner wall of the processing chamber 1, and the output end of the hydraulic cylinders 601 being connected to the top of the assembly frame 602.

[0045] In this embodiment, the hydraulic cylinder 601 is used to drive the assembly frame 602 to move up or down. In this way, the abrasive assembly can contact the positive electrode plate above the cleaning table 403, thereby realizing the grinding work of the positive electrode plate. At the same time, due to the sliding fit between the assembly frame 602 and the inner wall of the processing chamber 1, the stability and accuracy of the processing process are ensured.

[0046] In a further preferred embodiment of the present invention, such as Figure 1-2 As shown, the abrasive assembly further includes: a plurality of grinding wheels 603 horizontally and rotatably disposed between the assembly frames 602, the plurality of grinding wheels 603 being connected to each other by a chain wheel assembly; and a third motor 604 disposed on the outside of the assembly frame 602, the output end of the third motor 604 being fixedly connected to the end of one of the grinding wheels 603 by a key.

[0047] In this embodiment, the third motor 604 drives the grinding wheel 603 connected to it to rotate, and the chain wheel group ensures the synchronous rotation of the grinding wheel 603, so that all the grinding wheels 603 work at the same time to process and grind the upper surface of the positive electrode sheet, thereby improving the processing range.

[0048] In a further preferred embodiment of the present invention, such as Figure 1-7 As shown, a water tank 7 is provided on the top of the treatment chamber 1, and a flexible tube 8 is connected to the outside of the assembly frame 602 through a limiting block 14. The flexible tube 8 is connected to the water tank 7, and a spray head 9 is connected to the end of the flexible tube 8 away from the water tank 7.

[0049] In this embodiment, during the processing, when the equipment is started, the water tank 7 begins to supply water, which is then transported to the spray head 9 through the flexible pipe 8. The spray head 9 sprays water onto the positive electrode plate of the cleaning platform 403, thereby achieving the effect of wetting and cooling the positive electrode plate.

[0050] In a further preferred embodiment of the present invention, such as Figure 1-2 As shown, the outer walls on both sides of the processing chamber 1 are provided with discharge pipes 10 that communicate with its inner cavity.

[0051] In this embodiment, the processed material can be discharged from the processing chamber 1 more effectively.

[0052] In a further preferred embodiment of the present invention, such as Figure 1-3 As shown, the bottom side of the discharge pipe 10 is connected to a filter box 11, a filter screen 12 is provided inside the filter box 11, and a discharge port 13 is opened on the bottom side of the filter box 11.

[0053] In this embodiment, the material is discharged through the discharge pipe 10. Some fine particles and impurities may be discharged along with the material. In order to ensure the purity of the wastewater, these impurities need to be filtered out. Therefore, the bottom side of the discharge pipe 10 is connected to a filter box 11. A filter screen 12 is installed inside the filter box 11. After the material is filtered by the filter screen 12, fine particles and impurities will be intercepted on the filter screen 12. In this way, the material can be filtered and separated to obtain a higher quality treatment result.

[0054] Working principle: The positive electrode sheet to be processed is placed in the limiting groove 502. The function of the limiting groove 502 is to restrict the movement of the positive electrode sheet and ensure that its position is fixed during the processing. The function of the return spring 503 is to keep the positive electrode sheet in the limiting groove 502 stable. When the positive electrode sheet is placed in the limiting groove 502, the return spring 503 will spring it back to its original position to ensure the accurate position of the positive electrode sheet. Each of the return springs 503 is equipped with a damper to slow down the rebound speed of the return spring 503, making the placement and removal of the positive electrode sheet more stable. In conjunction with the magnetic suction plate 501, it firmly attracts the positive electrode sheet to its surface through magnetic force, ensuring the stability and accuracy of the positive electrode sheet during the processing.

[0055] Two first motors 203 drive the screws 202 to rotate respectively. Because the connecting block 204 slides with the inner wall of the assembly shell 201, the connecting block 204 can only drive the upper scraping component to move horizontally along the processing chamber 1, thereby adjusting the distance between the two scrapers 305 and the positive electrode sheet, so as to carry out cleaning activities on positive electrode sheets of different sizes. When the outer wall of the positive electrode sheet is polished, the motor of the lead screw slide 304 drives its moving end to drive the scraper 305 to move horizontally in the longitudinal direction. In the reciprocating motion, the inclined blade of the scraper 305 effectively scrapes the side wall of the positive electrode sheet during the movement.

[0056] The second motor 402 is used to drive the cleaning table 403 to rotate, thereby realizing multi-angle cleaning of the positive electrode sheet and improving the comprehensiveness of the cleaning.

[0057] The third motor 604 drives the grinding wheel 603 connected to it to rotate. The chain wheel group ensures the synchronous rotation of the grinding wheel 603, so that all the grinding wheels 603 work at the same time to process and grind the upper surface of the positive electrode sheet, thereby improving the processing range.

[0058] During the positive electrode processing, the water tank 7 starts to supply water and delivers it to the spray head 9 through the flexible pipe 8. The spray head 9 sprays water onto the positive electrode on the cleaning table 403, achieving the effect of wetting and cooling the positive electrode.

[0059] Finally, the material is discharged through the discharge pipe 10. During the discharge process, some fine particles and impurities may be discharged with the material. In order to ensure the purity of the wastewater, these impurities need to be filtered out. Therefore, the bottom of the discharge pipe 10 is connected to a filter box 11. The filter box 11 is equipped with a filter screen 12. After the material is filtered by the filter screen 12, fine particles and impurities will be intercepted on the filter screen 12. In this way, the material can be filtered and separated to obtain a higher quality treatment result.
