Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery material repair, and in particular to a lithium iron phosphate battery electrode repair immersion device. Background Art

[0002] Lithium batteries are batteries that use lithium metal or lithium alloy as anode materials and non-aqueous electrolyte solutions. Lithium batteries are widely used in people's lives, so there are a large number of them in existence, including many waste lithium batteries, which need to be recycled and repaired.

[0003] At present, the recycling methods of waste lithium iron phosphate battery positive electrode materials can be mainly divided into indirect regeneration and direct regeneration. The indirect regeneration method adopts alkaline dissolution, inorganic / organic acid leaching, biological leaching and other processes, and is combined with pH adjustment, extraction and other impurity removal methods. First, lithium, iron and phosphorus are leached into the solution, and then the obtained lithium, iron and phosphorus solution is added with a precipitant for step-by-step precipitation to obtain the corresponding lithium, iron and phosphorus salts as precursors to re-synthesize new lithium iron phosphate positive electrode materials.

[0004] In the prior art, the positive electrode material needs to be soaked multiple times before repair. After the first soaking, the positive electrode material needs to be taken out of the soaking liquid and placed on a screening device for screening. The screened positive electrode material is then soaked and filtered again, and then dried. However, in actual operation, there are too many devices used to repair and process the positive electrode material, resulting in too complicated operation steps and high energy consumption. In addition, due to the large number of waste lithium batteries to be processed, workers need to frequently collect and transport the positive electrode materials. Working for a long time will cause workers to be tired, affecting work efficiency, and working in a tired state will affect the quality of processing. Summary of the Invention

[0021] Beneficial effects of the present invention:

[0022] (1) The present invention realizes the repair of positive electrode powder by soaking components and filtering components. First, before repair, the battery positive electrode powder needs to be placed in liquid for dispersion to obtain slurry after dispersion, and then the slurry is precipitated to obtain precipitate. After obtaining the precipitate, it is placed in the soaking component, and then ammonia water is added for soaking, and it is stirred while soaking. After stirring, it is transported to the filtering component, and the positive electrode powder is separated into solid and liquid by the filtering component. After separation, it is transported to the impurity removal component for impurity removal, and finally the impurity-removed battery positive electrode powder is obtained.

[0023] (2) The present invention realizes the repair and screening of powder by a filter bin. Ammonia water is added to the soaking bin, and then the positive electrode powder sediment is placed in the soaking bin for soaking. The powder is stirred during the soaking process. After the stirring is completed, the liquid and the powder are transported to the connecting bin through the conveying pipe, and then fall into the filter sieve plate in the filter bin. The filter sieve plate is arranged in an arc shape. When the powder reaches the filter sieve plate, it will slide to the middle of the filter sieve plate, so that the powder is spread flat on the filter sieve plate. The bidirectional screw in the cleaning bin is driven to rotate. When rotating, it will drive the moving block to move left and right. During the movement, it drives the scraper to scrape the powder into the guide bins on both sides. When scraping the powder, the powder can be quickly screened and the liquid separated.

[0024] (3) The present invention realizes the driving connection between the soaking tank and the filtering tank through the transmission component. When the liquid in the soaking tank enters the delivery pipe, the inertia of the falling liquid will hit the water flow plate. The water flow plate can drive the transmission rod to rotate when it hits. When the transmission rod rotates, it will drive the first transmission gear at the other end to rotate, and then drive the second transmission gear to rotate through the transmission belt. The rotation of the second transmission gear will drive the connecting shaft to rotate, and then use the connecting shaft to drive the second connecting gear to rotate. The second connecting gear is meshed with the first connecting gear, and then drives the first connecting gear and the two-way screw to rotate. The rotation of the two-way screw can drive the scraper to work, and the greater the water flow, the faster the scraper moves. The rotation speed of the two-way screw is adjusted according to the size of the water flow.

[0025] (4) The present invention realizes the clamping of the iron removal tray through the clamping assembly. When the iron removal tray is pulled out, the staff needs to pull the pull rod. When pulling, the pull rod drives the clamping block to move toward the top plate, and then the clamping block is disengaged from the clamping slot. After disengagement, the telescopic spring in the bottom slot rebounds, and the iron removal tray can be ejected out of the de-dusting bin a little through the bottom plate, and then it can be pulled out. When installing the iron removal tray, the iron removal tray is first inserted into the de-dusting bin. When inserted, the bottom of the iron removal tray contacts the clamping block, and after contact, the clamping block is squeezed into the clamping box. When the iron removal tray is fully inserted into the de-dusting bin, the clamping block and the clamping slot are in a parallel position. At this time, the clamping spring rebounds, and the clamping block is ejected into the clamping slot. At the same time, the iron removal tray squeezes the bottom plate into the bottom slot. When the iron removal tray needs to be pulled out, the pull rod can be pulled. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] During operation, the positive electrode material needs to be soaked multiple times before repair. After the first soaking, the positive electrode material needs to be taken out of the soaking liquid and placed on a screening device for screening. The screened positive electrode material is then soaked and filtered again, and then dried. However, in actual operation, there are too many devices used to repair and process the positive electrode material, which makes the operation steps too complicated and consumes a lot of energy. In addition, due to the large number of waste lithium batteries to be processed, workers need to frequently collect and transport the positive electrode material. Long working hours make workers tired, affecting work efficiency, and working in a tired state will affect the quality of processing. In order to prevent such incidents from happening, first, before repair, the battery positive electrode powder is placed in a liquid for dispersion. After dispersion, a slurry is obtained.

The powder is stirred during the soaking process. After stirring, the liquid and the powder are transported to the connecting bin 25 through the conveying pipe 15, and then fall into the filter sieve plate 22 in the filter bin 21. The filter sieve plate 22 is arranged in an arc shape. When the powder reaches the filter sieve plate 22, it will slide to the middle of the filter sieve plate 22, so that the powder is spread flat on the filter sieve plate 22. The bidirectional screw 62 in the cleaning bin 61 is driven to rotate, and the rotation will drive the moving block 63 to move left and right. During the movement, the scraper 64 is driven to scrape the powder into the guide bin 26 on both sides, and when scraping the powder, the powder can be quickly sieved and separated from the liquid.

[0049] like Figure 4 and Figure 5 The transmission assembly 3 includes a fixed block 31; the fixed block 31 is fixedly connected to the top of the connecting bin 25; the inner side wall of the conveying pipe 15 is rotatably connected to the transmission rod 32; the transmission rod 32 passes through the conveying pipe 15 and is arranged on the fixed block 31; the end of the transmission rod 32 away from the fixed block 31 is fixedly connected to the first transmission gear 34; the end of the transmission rod 32 away from the first transmission gear 34 is fixedly connected to the water flow plate 33; the water flow plate 33 is provided with multiple groups and is located in the conveying pipe 15; the side wall of the cleaning bin 61 is rotatably connected to the connecting shaft 39; the end of the connecting shaft 39 away from the cleaning bin 61 is fixedly connected to the second transmission gear 36; the first transmission gear 34 and the second transmission gear 36 are sleeved on the transmission belt 35; the middle of the connecting shaft 39 is fixedly connected to the second connecting gear 37; the side wall of the cleaning bin 61 is rotatably connected to the first connecting gear 38; the first connecting gear 38 is fixedly connected to the output end of the two-way screw rod 62; the first connecting gear 38 is meshed with the second connecting gear 37;

The water flow plate 33 can drive the transmission rod 32 to rotate when it hits. When the transmission rod 32 rotates, it will drive the first transmission gear 34 at the other end to rotate, and then drive the second transmission gear 36 to rotate through the transmission belt 35.

The second connecting gear 37 is meshed and connected with the first connecting gear 38, and then drives the first connecting gear 38 and the bidirectional screw rod 62 to rotate. The rotation of the bidirectional screw rod 62 can drive the scraper 64 to work, and the greater the water flow, the faster the scraper 64 moves. The rotation speed of the bidirectional screw rod 62 is adjusted according to the size of the water flow.

[0051] like Figure 7As shown, the impurity removal component 4 includes a impurity removal bin 41; the end of the guide bin 26 away from the filter bin 21 is fixedly connected to the impurity removal bin 41; the inner wall of the impurity removal bin 41 is slidably connected to an iron removal tray 44; the top of the impurity removal bin 41 is rotatably connected to a fan shaft 46; the fan shaft 46 is fixedly connected to a fan blade 47; the fan blade 47 is provided with multiple groups; the side wall of the impurity removal bin 41 is fixedly connected to a heating pipe 42; the heating pipe 42 is provided below the fan blade 47; the side wall of the impurity removal bin 41 is provided with a clamping assembly 7; the iron removal tray 44 is clamped by the clamping assembly 7;

[0052] During operation, the filtered powder enters the impurity removal bin 41 through the guide bin 26 and reaches the iron removal tray 44. Then the heating tube 42 and the fan blade 47 are turned on for heating and drying. When the heating tube 42 is turned on, heat is generated. Then, the heat can be evenly transferred to the powder in the iron removal tray 44 through the rotation of the fan blade 47, thereby achieving rapid drying. The iron removal tray 44 can adsorb the iron element in the powder to achieve the impurity removal effect. After the drying work is completed, the iron removal tray 44 can be pulled out.

[0053] like Figure 7-10 As shown, the clamping assembly 7 includes a clamping box 71; the top of the clamping box 71 is fixedly connected to a top plate 72; the side wall of the top plate 72 is fixedly connected to a clamping spring 74; the end of the clamping spring 74 away from the top plate 72 is fixedly connected to a clamping block 75; the side wall of the iron removal tray 44 is provided with a clamping groove 441; the inner diameter of the clamping groove 441 is consistent with the size of the clamping block 75; the side wall of the clamping block 75 is fixedly connected to a pull rod 73; the pull rod 73 is arranged through the top plate 72; the side wall of the debris removal bin 41 is provided with a bottom groove 411; the bottom groove 411 is fixedly connected to a telescopic spring 412; the end of the telescopic spring 412 away from the bottom groove 411 is fixedly connected to the bottom plate 413; the end of the bottom plate 413 away from the telescopic spring 412 abuts against the iron removal tray 44;

[0054] When working, when pulling out the iron removal tray 44, the staff needs to pull the pull rod 73. When pulling, the pull rod 73 drives the clamping block 75 to move toward the top plate 72, and then the clamping block 75 is disengaged from the clamping slot 441. After disengagement, the telescopic spring 412 in the bottom groove 411 rebounds, and the iron removal tray 44 can be ejected from the debris removal bin 41 a little through the bottom plate 413, and then it can be pulled out. When installing the iron removal tray 44, first insert the iron removal tray 44 into the debris removal bin 41. When inserted, the bottom of the iron removal tray 44 contacts the clamping block 75, and after contact, the clamping block 75 is squeezed into the clamping box 71. When the iron removal tray 44 is fully inserted into the debris removal bin 41, the clamping block 75 and the clamping slot 441 are in a parallel position. At this time, the clamping spring 74 rebounds and bounces the clamping block 75 into the clamping slot 441. At the same time, the iron removal tray 44 squeezes the bottom plate 413 into the bottom groove 411. When the iron removal tray 44 needs to be pulled out, just pull the pull rod 73.

[0058] During operation, after the delivery valve 16 is opened, the liquid in the soaking tank 11 can reach the filter tank 21 from the delivery pipe 15, and the water flow rate can be controlled according to the size of the opening of the delivery valve 16, thereby controlling the movement speed of the scraper 64, and the stirring motor 14 can drive the stirring shaft 12 to rotate.

[0059] like Figure 3 As shown, the bottom of the filter bin 21 is fixedly connected to a drain pipe 23; the drain pipe 23 is fixedly connected to a drain valve 24; the top of the impurity removal bin 41 is fixedly connected to a fan motor 45; the fan shaft 46 is connected and driven by the fan motor 45;

[0060] During operation, the separated liquid can be discharged from the drain pipe 23, and the fan motor 45 can drive the fan shaft 46 to rotate.

[0061] The working principle of the present invention is as follows: the positive electrode material needs to be soaked multiple times before repair. After the first soaking, the positive electrode material needs to be taken out of the soaking liquid and placed on a screening device for screening. The screened positive electrode material is then soaked and filtered again, and then dried. However, in actual operation, there are too many devices used to repair and process the positive electrode material, which makes the operation steps too complicated and consumes a lot of energy. In addition, due to the large number of waste lithium batteries to be processed, workers need to frequently collect and transport the positive electrode material. Long working hours make workers tired, affecting work efficiency, and working in a tired state will affect the quality of treatment. In order to prevent such incidents from happening, first, before repair, the battery positive electrode powder is placed in a liquid for dispersion, and a slurry is obtained after dispersion. The slurry is then precipitated to obtain a precipitate. After obtaining the precipitate, it is placed in a soaking component 1, and then ammonia water is added for soaking. It is stirred while soaking. After stirring, it is transported to a filtering component 2. The positive electrode powder is separated into solid and liquid by the filtering component 2. After separation, it is transported to a cleaning component 4 for impurity removal, and finally the cleaned battery positive electrode powder is obtained.

[0062] Among them, when the liquid in the soaking tank 11 enters the delivery pipe 15, the inertia of the falling liquid will hit the water flow plate 33. The water flow plate 33 can drive the transmission rod 32 to rotate when it hits. When the transmission rod 32 rotates, it will drive the first transmission gear 34 at the other end to rotate, and then drive the second transmission gear 36 to rotate through the transmission belt 35. The rotation of the second transmission gear 36 will drive the connecting shaft 39 to rotate, and then use the connecting shaft 39 to drive the second connecting gear 37 to rotate. The second connecting gear 37 is meshed and connected with the first connecting gear 38, and then drives the first connecting gear 38 and the bidirectional screw rod 62 to rotate. The rotation of the bidirectional screw rod 62 can drive the scraper 64 to work, and the greater the water flow, the faster the scraper 64 moves. The rotation speed of the bidirectional screw rod 62 is adjusted according to the size of the water flow.
