Description

Technical Field

[0001] This utility model relates to the field of positive electrode acidification treatment, and specifically to a positive electrode surface acidification treatment device. Background Technology

[0002] Acidification of the cathode surface is a technique that uses a specific acid solution to chemically treat the surface of the cathode material to change its surface chemical properties, structure or morphology, thereby optimizing the material performance. Through acidification, impurities or oxide layers on the surface of the cathode material can be removed, surface roughness can be increased, and the contact area between the material and the electrolyte can be increased, thereby improving the battery's charge and discharge efficiency, cycle stability and other electrochemical performance.

[0003] A search revealed a utility model patent with publication number CN207038651U, which discloses a formation tank for battery formation. The tank is a rectangular structure with grooves. Detachable door panels are provided on both sides of the formation tank along its width direction. A connecting device is provided between the detachable door panels and the formation tank. An inlet and an outlet are provided at the bottom of the formation tank. A transmission device is provided at the bottom of the formation tank. The transmission device includes a trolley and a bidirectional track laid at the bottom of the formation tank. The trolley is equipped with a lifting device, and wheels are provided at the bottom of the trolley, with the wheels in close contact with the track. A drive shaft is provided between the wheels in the same row, and a motor is connected to any one of the drive shafts. Baffles are also provided on both side walls of the formation tank, with the height of the baffles lower than the highest point of the trolley. This utility model realizes automatic battery transfer into the formation tank, greatly liberating labor, reducing production costs, and significantly improving work efficiency.

[0004] In the existing acidification process, the positive electrode needs to be placed in the formation tank for acidification. However, the support plate inside the formation tank is usually designed to be hollow to facilitate the immersion of the solution and the placement of the positive electrode. When the positive electrode is placed on the hollow support plate, a part of the bottom of the positive electrode will be in contact with the support plate, resulting in incomplete acidification.

[0005] Therefore, it is necessary to invent a positive electrode surface acidification treatment device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a positive electrode surface acidification treatment device. By rotating and stirring the solution, the rotational power is converted into the up-and-down movement power of the push plate, so that the positive electrode can move up and down repeatedly within the sieve frame on the support plate, thereby enabling the bottom of the positive electrode to be fully acidified, thus solving the problem of incomplete positive electrode surface acidification treatment in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a positive electrode surface acidification treatment device, including an acidification treatment tank, a support plate installed above the inner wall of the acidification treatment tank, a plurality of sets of sieve frames sequentially installed on the support plate, through grooves sequentially opened on the surface of the support plate inside the sieve frames, and through grooves opened on the support plate between each set of sieve frames.

[0008] The agitation assembly installed in the acidification treatment tank includes a motor, which is installed outside the acidification treatment tank. The output end of the motor is connected to a rotating shaft, and the rotating shaft is located inside the acidification treatment tank.

[0009] The pushing component installed in the acidification treatment tank includes a connecting plate, with guide blocks symmetrically installed on both sides of the connecting plate. Guide grooves are symmetrically opened on the inner wall of the acidification treatment tank, and the guide grooves are slidably connected to the corresponding guide blocks.

[0010] Preferably, the agitation assembly further includes a rocker arm, which is mounted on the end of the rotating shaft away from the motor.

[0011] Preferably, a stirring paddle is rotatably connected below the support plate, and rocker arms two are symmetrically mounted on the stirring paddle, with rocker arms two and rocker arms one facing each other.

[0012] Preferably, the pushing assembly further includes a connecting arm, which is rotatably connected between each set of rocker arms one and two, and the upper part of the connecting arm is rotatably connected to the bottom of the connecting plate.

[0013] Preferably, connecting rods are sequentially installed above the connecting plate, and a push plate is installed above each set of connecting rods. The push plate is slidably connected to the corresponding through groove, and multiple sets of through holes are opened on the surface of the push plate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] The motor drives the rotating shaft to rotate, which in turn rotates rocker arms one and two, causing the stirring paddle to rotate as well. This stirs the solution and improves the acidification effect with the positive electrode. At the same time, rocker arms one and two can push the connecting arm up and down, causing the push plate to move the positive electrode up and down within the sieve frame. This allows the bottom of the positive electrode to undergo effective all-round acidification. This structure allows the positive electrode to move up and down repeatedly, enabling the solution to undergo an all-round acidification reaction. The up and down movement during the reaction process improves the acidification effect, and the stirring paddle further enhances the acidification effect, thereby improving the quality of the positive electrode acidification treatment.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 A positive electrode surface acidification treatment device is shown, including an acidification treatment tank 001. A support plate 101 is installed on the upper part of the inner wall of the acidification treatment tank 001. Multiple sets of screen frames 103 are sequentially installed on the support plate 101. Through grooves 102 are sequentially opened on the surface of the support plate 101 inside the screen frames 103. Through grooves 104 are opened on the support plate 101 between each set of screen frames 103.

[0026] Acidification is performed by placing the positive electrode inside the sieve frame 103, and the through groove 102 and the through groove 104 ensure that the treatment solution enters above the support plate 101, and the liquid level needs to cover the sieve frame 103.

[0027] The agitation assembly 002 installed in the acidification treatment tank 001 includes a motor 201. The motor 201 is installed outside the acidification treatment tank 001. The output end of the motor 201 is connected to a rotating shaft 202, and the rotating shaft 202 is located inside the acidification treatment tank 001.

[0028] The motor 201 can drive the rotating shaft 202 to rotate, thereby causing the rotating shaft 202 to rotate inside the acidification treatment tank 001.

[0029] The push assembly 003 installed in the acidification treatment tank 001 includes a connecting plate 302, guide blocks 303 are symmetrically installed on both sides of the connecting plate 302, and guide grooves 304 are symmetrically opened on the inner wall of the acidification treatment tank 001, and the guide grooves 304 are slidably connected to the corresponding guide blocks 303.

[0030] Through the cooperation of the guide groove 304 and the guide block 303, the connecting plate 302 can move up and down in the acidification treatment tank 001.

[0031] Furthermore, in the above structure, the agitation assembly 002 also includes a rocker arm 203, which is mounted on the end of the rotating shaft 202 away from the motor 201.

[0032] The motor 201 can drive the rocker arm 203 to rotate by rotating the shaft 202.

[0033] Furthermore, in the above structure, a stirring paddle 204 is rotatably connected below the support plate 101, and rocker arms 205 are symmetrically mounted on the stirring paddle 204, with rocker arms 205 and rocker arms 203 facing each other.

[0034] By cooperating with rocker arm 205 and rocker arm 203, the stirring paddle 204 can rotate synchronously, allowing the stirring paddle 204 to agitate the acidified solution, thereby better reacting the electrode plates.

[0035] Furthermore, in the above structure, the pushing component 003 also includes a connecting arm 301, which is rotatably connected between each set of rocker arms 1 203 and rocker arms 205, and the upper part of the connecting arm 301 is rotatably connected to the bottom of the connecting plate 302.

[0036] The connecting arm 301 allows rocker arms 203 and 205 to rotate synchronously, thereby enabling rocker arms 203 and 205 to push the connecting arm 301 to move.

[0037] Furthermore, in the above structure, connecting rods 305 are sequentially installed above the connecting plate 302, and a push plate 306 is installed above each set of connecting rods 305. The push plate 306 is slidably connected to the corresponding through groove 102, and multiple sets of through holes 307 are opened on the surface of the push plate 306.

[0038] The connecting arm 301 can drive the push plate 306 above the connecting plate 302 to move along the through groove 102, thereby pushing the positive electrode up in the sieve frame 103. This allows the bottom of the positive electrode to be effectively acidified. Furthermore, the up-and-down movement of the positive electrode can further enhance the reaction between the positive electrode and the acidified solution. The through hole 307 allows the solution to have better contact with the bottom of the positive electrode when the push plate 306 moves up and down.

[0039] The working principle of this practical application is as follows:

[0040] Refer to the instruction manual appendix Figure 1-5 By placing the positive electrode into the sieve frame 103, the motor 201 is started, causing the rotating shaft 202 to rotate. This causes the rocker arms 203 and 205 to rotate synchronously, driving the connecting arm 301. Simultaneously, the stirring paddle 204 stirs the solution, allowing it to react better with the positive electrode. The connecting arm 301 pushes the connecting plate 302 upward, causing the guide block 303 to slide along the guide groove 304. This causes the connecting rod 305 to push the push plate 306, which in turn pushes the positive electrode in the sieve frame 103 up and down, allowing the bottom of the positive electrode to undergo a comprehensive acidification reaction. This structure allows the positive electrode to move up and down repeatedly, enabling the solution to undergo a comprehensive acidification reaction. The up-and-down movement during the reaction improves the acidification effect, and the stirring paddle 204 further enhances the acidification effect, thus improving the quality of the positive electrode acidification treatment.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
