Description

Technical Field

[0002] Electrode sheets are an important component of new energy batteries. The surface of electrode sheets needs to be ground and polished before assembly, otherwise the actual service life of the battery will be seriously affected. At present, the grinding device used for grinding electrode sheets will directly allow metal debris to enter the grinding fluid during the grinding process. When a certain amount of metal debris accumulates in the grinding fluid, the grinding fluid will become ineffective. The ineffective grinding fluid must be manually cleaned out of the grinding tank. On the one hand, the fluid needs to be changed frequently, which increases the labor intensity of on-site workers. On the other hand, the grinding fluid cannot be reused and needs to be replaced frequently, which results in high production costs. Summary of the invention

[0015] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0016] See also Figure 1 , the embodiment of the present invention includes:

[0017] A continuous grinding device for electrode sheets, comprising: a grinding mechanism, a circulating sedimentation tank 6 and a filtering mechanism, wherein the grinding mechanism comprises a grinding controller 1 and a grinding trough 2, wherein a waste chip baffle 3 for preventing metal chips from being deposited is installed at the bottom of the grinding trough 2, wherein the grinding controller 1 is installed on the outside of the trough wall at the top of the grinding trough 2, wherein the filtering mechanism comprises a filtering tank 9 and a filtering controller 8, wherein the circulating sedimentation tank 6 and the filtering tank 9 are arranged around the grinding trough 2, wherein the filtering controller 8 is installed on the outside of the pool wall of the filtering tank 9 and is located on the same side of the continuous grinding device for electrode sheets as the grinding controller 1, wherein a water supply pipe 14 and a water quality sensor 13 extending into the filtering tank 9 are installed on the filtering controller 8.

[0018] The notch of the grinding tank 2 is higher than the circulating sedimentation tank 6. An overflow hole is provided on the wall of the grinding tank 2. The circulating sedimentation tank 6 is connected to the overflow hole through a first circulating pipe 4. The first circulating pipe 4 is provided with a flow control valve 5, which can control the speed of the grinding liquid entering the circulating sedimentation tank 6 as needed.

[0019] The filter pool 9 is provided with a cross-shaped partition to divide the filter pool into 4 sub-pools. Overflow water inlet holes are arranged in sequence on the partitions between the 4 sub-pools to form a one-way series structure. The heights of all overflow holes are the same. A fine filter 10 is installed in each sub-pool. The water inlet pipe of the fine filter 10 in the next sub-pool in the series structure is connected to the overflow water inlet hole on the partition between the two. A water outlet connected to the outside is arranged on the wall of the first pool among the 4 sub-pools. The height of the water outlet is the same as the overflow hole. The water inlet holes have the same height. A second circulation pipe 12 is provided between the water outlet and the circulation sedimentation tank 6. An auxiliary water pump 11 is installed on the second circulation pipe 12. The water inlet pipe of the fine filter 10 in the first tank is connected to the second circulation pipe 12 through the water outlet. An overflow pipe 15 passing through the wall of the tail tank is installed on the tail tank in the four sub-tanks. The outlet end of the overflow pipe 15 is located directly above the grinding tank 2. The water quality sensor 13 and the water supply pipe 14 are also connected to the tail tank. Through the mode of connecting multiple sub-tanks in series, the grinding liquid can be dynamically circulated and filtered to effectively remove metal debris impurities in the grinding liquid and reuse it, reducing the waste of water resources. In addition, the water quality sensor 13 in the tail tank can perform online detection of water quality. When it is found that the filtration fails after multiple cycles, an alarm can be issued in time. After all the circulating liquid is cleaned out, the system is replenished with water through the water supply pipe 14 to continue grinding.

[0020] The circulating sedimentation tank is a closed structure as a whole, and a coarse filter 17 is provided between the first circulating pipe 4 and the second circulating pipe 12. The grinding tank 2 is a rectangle as a whole, and the circulating sedimentation tank 6 is L-shaped. The circulating sedimentation tank 6 and the filter tank 9 together surround the three sides of the grinding tank 2, and the installation position of the coarse filter 7 and the layout position of the first circulating pipe 4 are respectively on both sides of the corner position of the L-shape. The purpose of setting up such a structure is that on the one hand, the construction between the different parts is more compact and the space utilization rate is better. On the other hand, the circulating water in the circulating sedimentation tank 6 changes its flow direction through the corner position of the L-shape before passing through the coarse filter 7, which can improve the sedimentation efficiency of the debris in the front section of the circulating sedimentation tank 6 and reduce the pressure of coarse filtration.

[0021] The present embodiment is a further optimization of the existing traditional electrode sheet grinding device. By adopting a combination of an L-shaped circulating sedimentation tank 6 and a series multi-stage filtering tank 9, the rectangular grinding tank 2 is just surrounded in the middle. On the one hand, the various structures are compactly matched and the space utilization rate is high. On the other hand, during the grinding process, the grinding liquid in the grinding tank 2 is continuously circulated in the system by overflow, and the metal debris generated during the grinding process is brought into the circulating sedimentation tank 6 and the filtering tank 9. In this way, on the one hand, the whole process is carried out automatically, which significantly reduces the frequency of manual handling of the grinding liquid and reduces labor intensity. On the other hand, the grinding liquid is recycled, which reduces the amount of water replenished in the system and reduces resource waste.

[0022] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
