Description

An acid impregnation device for battery production plates Technical Field

[0001] This invention relates to the field of storage battery manufacturing technology, and in particular to an acid impregnation device for battery plates used in storage battery production. Background Technology

[0002] During the battery manufacturing process, positive and negative electrode pastes are sprayed onto the grid to form electrode plates. Before drying, the electrode plates need to be placed in an acid soaking tank containing concentrated sulfuric acid, so that the positive and negative electrode pastes react with the concentrated sulfuric acid to form a thin layer of lead sulfate on the surface of the electrode plates. Lead sulfate can prevent the electrode plates from cracking and increase the strength of the electrode plates. Technical issues

[0003] Traditional acid impregnation involves manually loading the electrode plates into an acid impregnation tank, which is then placed into the tank for reaction. However, this method is labor-intensive, and the handling process increases the risk of contact with concentrated sulfuric acid, potentially causing injury. Currently, a conveyor belt is often installed inside the impregnation tank. This belt moves the tank, which has perforated bottoms, allowing the electrode paste on the plates to react with concentrated sulfuric acid during movement. However, this method still has the following problems:

[0004] 1. During the process of conveying the pickling tanks, due to insufficient friction, the pickling tanks will accumulate in the pickling tank, requiring manual assistance to ensure the smooth operation of the conveyor belt, and affecting the conveying efficiency.

[0005] 2. A certain amount of concentrated sulfuric acid will remain in the acid soaking tank, which will corrode other equipment during the subsequent transfer process and affect the subsequent electrode drying time. Technical solutions

[0006] The purpose of this invention is to solve the problems in the prior art where, due to insufficient friction during the conveyor belt transport of the acid-soaking tank, the acid-soaking tank will accumulate in the acid-soaking tank, requiring manual assistance to ensure the smooth operation of the conveyor belt, which also affects the conveying efficiency. Furthermore, a certain amount of concentrated sulfuric acid will remain in the acid-soaking tank, which will corrode other equipment during subsequent transport and affect the subsequent electrode drying time. Therefore, this invention proposes an electrode plate acid-soaking device for battery production.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An acid-soaking device for battery production includes an acid-soaking tank, a support frame for supporting the plates disposed in the acid-soaking tank, and floating rollers arranged in an equidistant array within the support frame. It also includes a traction assembly for driving the roller frame to rise and fall; a cleaning tank disposed on one side of the acid-soaking tank; and a conveying assembly disposed in the cleaning tank. A spraying assembly for removing residual concentrated sulfuric acid from the surface of the acid-soaking tank is disposed on one side of the conveying assembly.

[0009] Preferably, two sets of first guide bars are symmetrically arranged on one side of the support, the first guide bars are slidably installed in the acid immersion tank, and the floating roller is rotatably arranged between the two sets of supports.

[0010] Preferably, the traction assembly includes two sets of traction ropes, and a first ear plate and a second ear plate are fixedly installed above the bracket and above the acid soaking tank, respectively. A pulley is rotatably installed on one side of both the first ear plate and the second ear plate, and the traction rope is wound around the pulley.

[0011] To ensure the stable lifting and lowering of the pickling tank within the pickling pool, the traction assembly further includes a first motor fixedly installed on the outer wall of the pickling pool. The output end of the first motor is connected to a traction shaft, which is rotatably installed on the outer wall of the pickling pool. Pulleys are also fixedly installed at both ends of the traction shaft. Cylinders are symmetrically installed on both sides of the first motor on the outer wall of the pickling pool.

[0012] Preferably, the conveying assembly includes a cleaning roller, the surface of which is arranged in a ring with equidistant ridges, the cleaning roller is configured as a hollow roller, and water outlet holes are provided inside the cleaning roller at positions avoiding the ridges.

[0013] To ensure the stability of the transmission structure between the cleaning rollers and to avoid overloading of the electrical equipment by using flexible transmission, thus ensuring the mechanical structure, a third synchronous pulley and a fourth synchronous pulley are fixedly installed at one end of the cleaning roller, a third motor is fixedly installed on the outside of the cleaning tank, and a second synchronous pulley is fixedly installed at the output shaft end of the third motor. The second synchronous pulley and the third synchronous pulley at the end of one set of cleaning rollers are connected by transmission, and the adjacent fourth synchronous pulleys are connected by transmission.

[0014] In order to provide water to the cleaning roller without affecting its rotation and conveying to the pickling tank, the cleaning roller is further connected to a first water pipe at one end, and a peristaltic pump is connected to the bottom of the first water pipe through an upper water pipe. The peristaltic pump is fixedly installed on one side of the outer wall of the cleaning tank, and a filter is connected to the bottom of the upper water pipe.

[0015] To remove residual concentrated sulfuric acid from the pickling tank, the spray assembly further includes symmetrical main pipes. One side of the main pipe is connected to a branch pipe via a pressure boosting valve, and one end of the branch pipe is connected to a nozzle. A rotary drive assembly is provided between the cleaning tank and the main pipe. The rotary drive assembly includes two sets of meshing racks and two sets of first gears. The two sets of first gears are fixedly installed at one end of the two sets of main pipes, and a guide wheel is rotatably installed at the other end of the main pipe. The guide wheel and the second guide bar are slidably connected.

[0016] To ensure the rotation of the two main pipes and their connection to the second water pipe, the spray assembly further includes two sets of positioning plates symmetrically arranged on one side of the inner wall of the cleaning tank. The second water pipe is fixedly installed in the positioning plate. The main pipe is rotatably connected to and connected between the two sets of second water pipes. The second water pipe is connected to the peristaltic pump.

[0017] To utilize the second motor to simultaneously control the rotation of two main pipes and maximize the removal of residue from the pickling tank, a fixed frame is further installed on one side of the cleaning tank. Second guide strips are provided on one side of the fixed frame and on the inner wall of the cleaning tank. A rack is slidably installed within the second guide strips. A screw is connected to one end of each of the two racks, and the two screws are threaded into an internal threaded sleeve. A second gear is connected to the surface of the internal threaded sleeve. A second motor is installed on the outer wall of the cleaning tank, and a drive rod is rotatably installed inside the cleaning tank. A first synchronous pulley is fixedly connected to the output shaft end of the second motor and one end of the drive rod. The two sets of first synchronous pulleys are connected in a transmission connection. An internal threaded sleeve is connected to one end of the drive rod, and the internal threaded sleeve meshes with the second gear. The fixed frame is located on one side. Beneficial effects

[0018] Compared with the prior art, the present invention provides an acid impregnation device for battery plates in battery production, which has the following advantages:

[0019] 1. The plate acid immersion device for battery production uses a floating roller that can be raised and lowered in the acid immersion tank to support the acid immersion tank. The traction component drives the floating roller to raise / lower according to production needs. The acid immersion tank and the floating roller used for support have a line contact structure to ensure that the acid immersion tank is wrapped with concentrated sulfuric acid as much as possible, so that the plates inside are fully immersed and the acid immersion effect is improved.

[0020] 2. The plate acid immersion device for battery production cleans the residual concentrated sulfuric acid on the surface of the acid immersion tank by using a spray assembly installed in the cleaning tank, which prevents corrosion of other equipment during subsequent transfer and shortens the subsequent plate drying time.

[0021] 3. The plate acid immersion device for battery production uses a cleaning roller to transport the acid immersion tank. The cleaning roller is hollow and water is injected into it by a water pump. The water is then pushed to the bottom of the acid immersion tank through the outlet hole to rinse the hard-to-clean surfaces and effectively remove concentrated sulfuric acid residue from the surface of the acid immersion tank.

[0022] All parts of this device not described herein are the same as or can be implemented using existing technologies. This invention ensures that the acid immersion tank is fully encased in concentrated sulfuric acid, allowing the internal electrode plates to be fully immersed and improving the acid immersion effect; it also prevents corrosion of other equipment during subsequent transfer and shortens the subsequent electrode plate drying time; water is pumped through the water outlet to the bottom of the acid immersion tank to rinse surfaces that are difficult to clean, effectively removing concentrated sulfuric acid residue from the surface of the acid immersion tank.

[0031] Type the description paragraph of the best embodiment of the invention here. Embodiments of the present invention

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example

[0034] Referring to Figures 1-7, an acid immersion device for battery production includes an acid immersion tank 1, a support 4 for supporting the plates disposed in the acid immersion tank 1, and floating rollers 3 arranged at equal intervals within the support 4.

[0035] In this embodiment, multiple sets of floating rollers 3 are used to support the acid immersion tank. The acid immersion tank and the floating rollers 3 used for support have a line contact structure, which ensures that the acid immersion tank is wrapped with concentrated sulfuric acid as much as possible, so that the electrode plates inside are fully immersed and the acid immersion effect is improved.

[0036] The traction assembly includes two sets of traction ropes 9. A first ear plate 6 and a second ear plate 7 are fixedly installed above the bracket 4 and above the acid soaking tank 1, respectively. A pulley 8 is rotatably installed on one side of both the first ear plate 6 and the second ear plate 7. The traction rope 9 is wound inside the pulley 8. Two sets of first guide bars 5 are symmetrically arranged on one side of the bracket 4. The first guide bars 5 are slidably installed in the acid soaking tank 1. The floating roller 3 is rotatably arranged between the two sets of brackets 4.

[0037] In this embodiment, the floating roller 3 is slidably installed in the acid soaking tank 1 via the bracket 4, and is wound around the pulley 8 in sequence by the traction rope 9. Starting the first motor 11 can pull the traction rope 9 to drive the floating roller 3 to sink or rise.

[0038] The pickling device also includes a traction assembly for driving the roller frame to rise and fall. The traction assembly also includes a first motor 11 fixedly installed on the outer wall of the pickling tank 1. The output end of the first motor 11 is connected to a traction shaft 10. The traction shaft 10 is rotatably installed on the outer wall of the pickling tank 1, and pulleys 8 are also fixedly installed at both ends of the traction shaft 10. Cylinders 12 are symmetrically installed on both sides of the first motor 11 on the outer wall of the pickling tank 1.

[0039] In this embodiment, the specific steps for controlling the pickling tank are as follows:

[0040] Start the first motor 11, which drives the traction shaft 10 to rotate. The pulleys 8 at both ends of the traction shaft 10 rotate and release the traction rope 9. One end of the traction rope 9 is connected to the pulley 8 on the first ear plate 6. Therefore, when the acid soaking tank is placed on the floating roller 3, it is supported by gravity and the floating roller 3 sinks, so that the battery production plates are completely immersed in the acid soaking tank 1.

[0041] After the acid immersion treatment, the first motor 11 is started to drive in reverse. The pulleys 8 at both ends of the traction shaft 10 rotate to wind up the traction rope 9, thereby pulling the first ear plate 6 to pull the supports 4 on both sides and the floating rollers 3 between the two sets of supports 4 and the acid immersion tank to rise to the outside of the concentrated sulfuric acid. The cylinder 12 is started to push the acid immersion tank above the cleaning pool 2.

[0042] The cleaning tank 2 is equipped with a conveying assembly, and a spraying assembly for removing residual concentrated sulfuric acid from the surface of the pickling tank is installed on one side of the conveying assembly.

[0043] In this embodiment, a cleaning tank 2 is added to one side of the acid soaking tank 1. The spraying components installed in the cleaning tank 2 are used to clean the residual concentrated sulfuric acid on the surface of the acid soaking tank, so as to avoid corrosion of other equipment during subsequent transfer and shorten the subsequent electrode drying time.

[0044] The conveying assembly includes a cleaning roller 13. The surface of the cleaning roller 13 has a ring of equidistant ridges 32. The cleaning roller 13 is a hollow roller. Water outlet holes 39 are opened in the cleaning roller 13 at positions that avoid the ridges 32.

[0045] In this embodiment, a cleaning roller 13 is provided in the cleaning tank 2. Adjacent cleaning rollers 13 are connected by a transmission. The cleaning roller 13 is used to clean the acid-soaking tank after acid soaking. At the same time, the cleaning roller 13 is set as a hollow structure. Water is injected into the cleaning roller 13 by a water pump. The water flow is impacted to the bottom surface of the acid-soaking tank through the water outlet 39 to rinse the surface that is difficult to clean, effectively removing the concentrated sulfuric acid remaining on the surface of the acid-soaking tank.

[0046] One end of the cleaning roller 13 is connected to the first water pipe 14, and the bottom of the first water pipe 14 is connected to the peristaltic pump 40 through the water supply pipe 33. The peristaltic pump 40 is fixedly installed on one side of the outer wall of the cleaning tank 2, and the bottom end of the water supply pipe 33 is connected to the filter 34.

[0047] In this embodiment, the peristaltic pump 40 is started, and the cleaning liquid in the cleaning tank 2 is pumped into the first water pipe 14 through the water inlet pipe 33 with filter 34. Then, it is poured into the cleaning roller 13. During the rotation, the cleaning roller 13 contacts the acid soaking tank with the convex 32 and moves the acid soaking tank to continuously transport it to the subsequent battery production process. At the same time, the convex 32 lifts the acid soaking tank to a certain height, so that the water outlet 39 can be smoothly discharged through the gap between the cleaning roller 13 and the acid soaking tank, so as to fully clean the residual acid soaking tank.

[0048] A third synchronous pulley 37 and a fourth synchronous pulley 38 are fixedly installed at one end of the cleaning roller 13. A third motor 35 is fixedly installed on one side of the outside of the cleaning tank 2. A second synchronous pulley 36 is fixedly installed at the output shaft end of the third motor 35. The second synchronous pulley 36 is connected to the third synchronous pulley 37 at the end of one set of cleaning rollers 13, and the adjacent fourth synchronous pulleys 38 are connected to each other.

[0049] Each cleaning roller 13 has a third synchronous pulley 37 and a fourth synchronous pulley 38 fixedly installed at one end. Adjacent third synchronous pulleys 37 are connected by a drive, and adjacent fourth synchronous pulleys 38 are also connected by a drive. At the same time, the end of one set of cleaning rollers 13 is connected by a drive through the third synchronous pulley 37 and the second synchronous pulley 36. When the third motor 35 is started, the third motor 35 drives the second synchronous pulley 36 at its shaft end to rotate, thereby driving the cleaning roller 13 to rotate and transport it to the pickling tank.

[0050] The spray assembly includes a symmetrical main pipe 17. One side of the main pipe 17 is connected to a branch pipe 19 via a pressure boosting valve 18. One end of the branch pipe 19 is connected to a nozzle 20. A rotary drive assembly is provided between the cleaning tank 2 and the main pipe 17. The rotary drive assembly includes two sets of meshing racks 24 and two sets of first gears 23. The two sets of first gears 23 are fixedly installed at one end of the two sets of main pipes 17. A guide wheel 25 is rotatably installed at the other end of the main pipe 17. The guide wheel 25 and the second guide bar 22 are slidably connected.

[0051] In this embodiment, a spraying assembly is provided on one side of the conveying assembly, and two sets of rotatable main pipes 17 are provided. A branch pipe 19 and a nozzle 20 are connected to one side of the main pipe 17. After the cleaning liquid is poured into the main pipe 17, it is sprayed into the pickling tank through the branch pipe 19 and the nozzle 20. At the same time, a pressure boosting valve 18 is provided in the branch pipe 19 to increase the spraying impact force and clean the concentrated sulfuric acid remaining on the surface of the pickling tank as much as possible.

[0052] The spray assembly also includes two sets of positioning plates 15 symmetrically arranged on one side of the inner wall of the cleaning tank 2. A second water pipe 16 is fixedly installed in the positioning plate 15. The main pipe 17 is rotatably connected and communicates between the two sets of second water pipes 16. The second water pipe 16 is connected to the peristaltic pump 40.

[0053] The two sets of main pipes 17 are connected and rotatably connected between the two sets of second water pipes 16. After the peristaltic pump 40 is connected to the second water pipes 16, the cleaning fluid is simultaneously poured into the main pipes 17.

[0054] A fixing frame 21 is fixedly installed on one side of the cleaning pool 2. A second guide strip 22 is provided on one side of the fixing frame 21 and on the inner wall of the cleaning pool 2. A rack 24 is slidably installed in the second guide strip 22. One end of each set of racks 24 is connected to a screw 28. The two sets of screws 28 are threadedly connected to an internal threaded sleeve 27. A second gear 26 is connected to the surface of the internal threaded sleeve 27. A second motor 29 is installed on the outer wall of the cleaning pool 2. A drive rod 30 is rotatably installed inside the cleaning pool 2. The output shaft end of the second motor 29 and one end of the drive rod 30 are fixedly connected to a first synchronous pulley 31. The two sets of first synchronous pulleys 31 are connected in a transmission connection. One end of the drive rod 30 is connected to the internal threaded sleeve 27. The internal threaded sleeve 27 meshes with the second gear 26.

[0055] In this embodiment, the main pipe 17 is driven to rotate by a certain angle, preferably ±55°, through a rotary drive assembly. Specifically, the second motor 29 is started, which drives the first synchronous pulley 31 at the output shaft end to rotate, transmitting the power to the first synchronous pulley 31 at the shaft end of the drive rod 30, thereby driving the drive rod 30 to rotate. A second gear 26 is provided at one end of the drive rod 30, and a second gear 26 is also fixedly installed on the surface of the internal threaded sleeve 27. The two sets of second gears 26 mesh, thereby driving the internal threaded sleeve 27 to rotate on one side of the inner wall of the cleaning tank 2. The two sets of screws 28 are respectively set as left-hand external threads and right-hand external threads. The inner wall of the internal threaded sleeve 27 is respectively provided with left-hand internal threads and right-hand internal threads that match the left-hand external threads and right-hand external threads. Therefore, by using the forward and reverse rotation of the second motor 29, the rotation of the internal threaded sleeve 27 can make the two sets of first racks 24 move closer or further apart, thereby driving the first gear 23 to rotate forward and reverse, ultimately realizing the forward and reverse rotation of the upper and lower sets of main pipes 17 within a certain angle range.

[0056] In this invention, initially, the floating roller 3 is horizontally suspended on the acid soaking tank 1, and the acid soaking box and the acid solution such as concentrated sulfuric acid in the acid soaking tank 1 are separated. The acid soaking box is placed on the floating roller 3, and the first motor 11 is started. The first motor 11 drives the traction shaft 10 to rotate, and the pulleys 8 at both ends of the traction shaft 10 rotate. The traction rope 9 is released. One end of the traction rope 9 is connected to the pulley 8 on the first ear plate 6. Therefore, after the acid soaking box is placed on the floating roller 3, under the action of gravity, the floating roller 3 supports the acid soaking box to sink, so that the battery production plates are completely immersed in the acid soaking tank 1.

[0057] After the acid immersion treatment, the first motor 11 is started to drive in reverse. The pulleys 8 at both ends of the traction shaft 10 rotate to wind up the traction rope 9, thereby pulling the first ear plate 6 to pull the supports 4 on both sides and the floating rollers 3 between the two sets of supports 4 and the acid immersion tank to rise to the outside of the concentrated sulfuric acid. The cylinder 12 is started to push the acid immersion tank above the cleaning pool 2.

[0058] The peristaltic pump 40 is started, and the cleaning solution in the cleaning tank 2 is pumped into the first water pipe 14 through the water inlet pipe 33 with filter 34. Then it is poured into the cleaning roller 13. During the rotation of the cleaning roller 13, the protrusion 32 contacts the acid soaking tank and moves the acid soaking tank to continuously convey it to the subsequent battery production process. At the same time, the protrusion 32 lifts the acid soaking tank to a certain height, so that the water outlet 39 can flow smoothly through the gap between the cleaning roller 13 and the acid soaking tank, and the acid soaking tank can be cleaned as thoroughly as possible.

[0059] The second motor 29 is started to rotate in both directions. The rotation of the internal threaded sleeve 27 causes the two sets of first racks 24 to move closer or further apart, thereby driving the first gear 23 to rotate in both directions. Ultimately, this achieves forward and reverse rotation of the upper and lower main tubes 17 within a certain angular range.

[0060] The peristaltic pump 40 fills the cleaning solution into the second water pipe 16 and then into the main pipe 17. It is then sprayed into the acid immersion tank through the branch pipe 19 and the nozzle 20. At the same time, a pressure boosting valve 18 is installed in the branch pipe 19 to increase the spraying impact force and clean the concentrated sulfuric acid remaining on the surface of the acid immersion tank as much as possible.

[0061] The second motor 29 drives the first synchronous pulley 31 at the output shaft end to rotate, which transmits the power to the first synchronous pulley 31 at the shaft end of the drive rod 30, thereby driving the drive rod 30 to rotate. The drive rod 30 drives the internal thread sleeve 27 to rotate on one side of the inner wall of the cleaning tank 2. The two sets of screws 28 are respectively set as left-hand external threads and right-hand external threads. The inner wall of the internal thread sleeve 27 is respectively provided with left-hand internal threads and right-hand internal threads that match the left-hand external threads and right-hand external threads. Therefore, by using the forward and reverse rotation of the second motor 29, the rotation of the internal thread sleeve 27 can make the two sets of first racks 24 move closer or further away from each other, thereby driving the first gear 23 to rotate forward and reverse. Finally, the upper and lower sets of main pipes 17 can rotate forward and reverse within a certain angle range, ensuring the spray cleaning range as large as possible.

[0062] 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.
