Description

Technical Field

[0001] This utility model relates to the technical field of lead-acid battery production equipment, and more specifically, to an acid washing tank for lead-acid battery production plates. Background Technology

[0002] In the production process of lead-acid batteries, the plate acid washing process plays a decisive role in battery performance. Its core is to remove the oxide layer, burrs and residual impurities through the chemical reaction between acid and the plate surface, thereby improving the conductivity and bonding force of the plate with the active material, laying the foundation for subsequent formation and assembly processes. The acid washing operation is usually carried out in a corresponding acid washing tank. There are many types of acid washing tanks on the market, and most of them directly place the plate acid inside for acid washing.

[0003] However, existing pickling tanks also have some shortcomings in use. For example, the electrode plates in existing pickling tanks are generally placed in a rather crude manner, often using simple frames for stacking. This can easily lead to overlap or tilting between the plates, resulting in uneven contact of the acid with the plate surface and causing localized over- or under-pickling. This directly affects the consistency of the plates, and some plates, due to incomplete removal of the oxide layer, are prone to rapid capacity decay during battery charging and discharging. In view of this, we propose an electrode plate pickling tank for lead-acid battery production. Utility Model Content

[0004] The purpose of this invention is to provide an acid washing tank for lead-acid battery production plates, so as to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pickling tank for lead-acid battery production includes a pickling tank body. A mesh support plate is fixedly installed on the bottom inner wall of the pickling tank body. The mesh support plate has a mesh-like plate structure. Multiple conical protrusions are fixedly installed on the upper surface of the mesh support plate. Multiple horizontal rods are fixedly installed on one side wall of the top of the pickling tank body. Multiple spacer rings are slidably connected to the horizontal rods. Multiple side cones are fixedly installed on both the left and right sides of the spacer rings. An end sealing rod for preventing the spacer rings from slipping off the horizontal rod is detachably installed at the end of the horizontal rod.

[0007] Preferably, a conical hopper is fixedly installed at the bottom of the pickling tank, and a drain pipe is fixedly installed at the bottom end of the conical hopper;

[0008] This setting facilitates subsequent waste liquid discharge operations.

[0009] Preferably, the plane containing the inner wall of the conical hopper is inclined downward at 45° to 60°, and a valve is fixedly installed on the sewage pipe;

[0010] This setting makes controlling waste liquid discharge much smoother.

[0011] Preferably, a circulation pump is provided on one side of the pickling tank, the inlet end of the circulation pump is connected to the conical hopper through a suction pipe, and the outlet end of the circulation pump is fixedly installed with an outlet pipe for acid flowout.

[0012] This setting enables the cyclical transport of acid.

[0013] Preferably, a top cover is hinged to the top surface of the pickling tank, and a sealing ring is embedded in the top surface of the pickling tank;

[0014] This feature allows the top cover to provide a seal.

[0015] Preferably, a flexible tube is fixedly installed at the end of the liquid outlet pipe, and a nozzle is fixedly installed at the end of the flexible tube. The nozzle is fixedly installed on the inner side of the top cover.

[0016] This setting allows the acid to be sprayed more smoothly along the nozzle.

[0017] Preferably, an acid addition pipe is fixedly installed on the top cylinder of the pickling tank, and an exhaust gas pipe is fixedly installed on the top cover.

[0018] Preferably, the end of the horizontal bar is provided with a groove, and the end of the end sealing bar is fixedly installed with a locking block, which is detachably installed on the bottom wall of the groove by fastening screws;

[0019] This feature facilitates the installation and removal of the end sealing rod. After the end sealing rod is installed, it prevents the spacer ring from slipping off the horizontal bar. After the end sealing rod is removed, the spacer ring can be removed from the horizontal bar normally.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model uses a sliding spacer ring and a side cone on a horizontal rod to adjust the spacing according to the size of the electrode plate. The top of the electrode plate rests against the side cone to avoid electrode plate overlap. The conical protrusion of the mesh support plate supports the bottom of the electrode plate, so that the surface of the electrode plate can fully contact the acid solution. This solves the problem of uneven pickling in the traditional placement method and achieves the effect of improving the consistency of the electrode plates.

[0022] 2. This utility model utilizes a circulating pump to circulate and spray the acid solution in the conical hopper through a suction pipe, a discharge pipe, and a nozzle. Combined with the sealing effect of the top cover, this improves the utilization rate of the acid solution. The conical hopper and the drain pipe facilitate the centralized discharge of waste liquid, achieving the effects of saving acid solution and facilitating sewage discharge.

[0023] 3. This utility model utilizes an end-sealing rod to prevent the spacer ring from slipping, an acid addition pipe for easy acid replenishment, and an exhaust gas pipe for exhausting waste gas, making operation convenient and enhancing the practicality of the equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-3This utility model provides a technical solution: an acid washing tank for lead-acid battery production plates, comprising an acid washing tank body 1, a mesh support plate 2 fixedly installed on the bottom inner wall of the acid washing tank body 1, the mesh support plate 2 having a mesh-like plate structure for normal acid flow operation; multiple conical protrusions 20 fixedly installed on the upper surface of the mesh support plate 2; multiple horizontal rods 3 fixedly installed on one side of the top wall of the acid washing tank body 1, one end of the horizontal rods 3 fixedly installed on the wall of the acid washing tank body 1; the horizontal rods... Multiple spacer rings 30 are slidably connected to the horizontal rod 3. Multiple side cones 31 are fixedly installed on both sides of the spacer rings 30. The end of the horizontal rod 3 is detachably installed with an end sealing rod 33 to prevent the spacer rings 30 from slipping off the horizontal rod 3. The spacing of the spacer rings 30 can be adjusted by sliding. The side cones 31 separate the electrode plates. The electrode plates are supported by the conical protrusions 20 of the mesh support plate 2, so that the electrode plates do not overlap. The acid solution fully contacts the surface of the electrode plates, making the pickling more uniform and improving the pickling quality of the electrode plates.

[0033] In this embodiment, the distance between two adjacent horizontal bars 3 increases sequentially from front to back, so that when the electrode plates of different sizes are placed between the corresponding two horizontal bars 3, the side part of the electrode plate can abut against the side cones 31 on the left and right spacer rings 30, and together with the conical protrusions 20, it can support the electrode plate.

[0034] like Figure 1 As shown, a conical hopper 10 is fixedly installed at the bottom of the pickling tank 1, and a drain pipe 11 is fixedly installed at the bottom end of the conical hopper 10. The inner wall of the conical hopper 10 is inclined downward at a angle of 45° to 60°. A valve 12 is fixedly installed on the drain pipe 11. The inclined inner wall of the conical hopper 10 guides the waste liquid to converge, and the valve 12 on the drain pipe 11 controls the discharge, making the waste liquid discharge more thorough and easier to control, thus achieving the effect of convenient waste liquid treatment.

The acid addition pipe 16 of the pickling tank 1 facilitates the replenishment of acid, and the exhaust pipe 18 of the top cover 17 discharges the exhaust gas generated by pickling. The exhaust pipe 18 is connected to an external exhaust gas treatment device, so that the acid is replenished in a timely manner and the exhaust gas is discharged in an orderly manner, thereby achieving the effect of optimizing operation and protecting the environment.

[0038] It is worth noting that the end of the horizontal bar 3 is provided with a groove 32, and the end of the end sealing bar 33 is fixedly installed with a locking block 34.

After the end sealing bar 33 is installed, it prevents the spacer ring 30 from slipping off the horizontal bar 3. After the end sealing bar 33 is removed, the spacer ring 30 can be normally removed from the horizontal bar 3.

[0039] Finally, it should be noted that the circulating pump 13, the corresponding control system, and the external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art.
