Description

Technical Field

[0001] The invention belongs to the technical field of battery processing, and in particular relates to an integrated acid dipping and curing device. Background Art

[0002] The positive plate of a tubular lead-acid battery is tubular in structure. A tubular cavity is formed by wrapping a tube around a lead rib, then filling the tube with lead powder and sealing it. There are three common lead powder filling processes: paste extrusion, grouting, and powder filling. The powder filling process, in particular, requires acid leaching and drying after the lead powder is poured into the tube to complete the plate production.

[0003] Currently, when tubular plates are pickled, they are directly stacked inside an acid tank filled with sulfuric acid. This processing method results in a large amount of acid mist escaping during the pickling process, which is difficult to collect. The plates are stacked tightly, which is not conducive to the diffusion of sulfuric acid, resulting in a long pickling time and poor pickling consistency. In addition, lead powder that falls off the surface of the plates during the pickling process will be deposited at the bottom of the acid tank, making it difficult to clean.

[0004] After the plates are acid-soaked, they need to be rinsed and dried to remove the moisture and acid inside the plates. During the rinsing operation, the plates need to be stacked on a rack and rinsed with pure water. Because the plates are placed closely together, it is difficult for pure water to rinse the plates cleanly. A large amount of pure water is needed, resulting in a waste of pure water resources. The water after rinsing contains sulfuric acid, which also increases the cost of sewage treatment. During the drying operation, the plates are placed in a drying chamber and hot air is used to remove the moisture inside the plates. However, because the plates are placed closely together, the plate drying efficiency is low and a large amount of heat energy is consumed. At the same time, after the plates are dried, they need to be cooled and then stacked neatly again before being put into storage. At the same time, the entire plate production process requires the plates to be stacked multiple times, which results in serious duplication of work and low work efficiency.

[0005] In order to solve the above problems, an integrated acid dipping and solidification device is provided. Summary of the Invention

[0015] As a preference of the above technical solution, one end of the cylinder located inside the cavity II is connected with a fin, and the movable end of the fin extends to the outside of the cavity II.

[0017] As a preference of the above technical solution, two cavities II in the frame II are arranged vertically and horizontally, and the frame II forms a "曰" shaped structure.

[0018] When controlling the movement of the cylinder, only need to control two opposite fins to approach each other, improving the convenience of pressing the cylinder.

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0038] Example 1

[0039] Figure 1 Shown is a schematic structural diagram of an integrated pickling and curing device as a specific embodiment of the present invention. Figure 2 Shown is a schematic structural diagram of a plate as a specific embodiment of the present invention.

[0040] refer to Figure 1 、 Figure 2 , acid-dipping and curing integrated device, including

[0041] The housing 10 has an open upper end. A first tube 30 and a second tube 40 are provided through the housing 10. The first tube 30 is located at the upper portion of the housing 10, and the second tube 40 is located at the lower portion of the housing 10.

[0042] The cover 20 is provided at the upper end of the housing 10 to seal the housing 10. In this embodiment, the cover 20 and the housing 10 are hingedly connected. In other embodiments, other connection methods can be used to ensure the sealing between the cover 20 and the housing 10;

[0043] The electrode plate 50 is provided with two ears 51;

[0044] The lap joint 60 is arranged inside the shell 10. The lap joint 60 includes at least two trusses 1 61, and trusses 2 62 distributed between and cross-arranged with the trusses 1 61. One lap ear 61 is correspondingly lapped on one truss 2 62.

[0045] In this solution, after the powder filling operation is completed, the electrode plate 50 is placed between the two trusses 62, and the ears 51 are hung on the trusses 62. When the electrode plates 50 are hung, the gaps between adjacent electrode plates 50 are controlled to facilitate the diffusion of sulfuric acid and water. After the hanging is completed, the cover 20 is used to seal the shell 10 to ensure the sealing between the cover 20 and the shell 10.

[0046] During the pickling operation, sulfuric acid is injected from the second tube 40. After the sulfuric acid immerses the electrode plate 50, the second tube 40 is closed and the electrode plate begins to be pickled. At the same time, the acid mist generated during the pickling process can be collected from the first tube 30. After the pickling of the electrode plate 50 is completed, the second tube 40 is opened to recover the remaining sulfuric acid.

[0047] During the cleaning operation, the second tube body 40 is closed and pure water is injected from the first tube body 30. When the water level submerges the electrode plate 50, the electrode plate 50 begins to be soaked and cleaned. After the electrode plate 50 is cleaned, the second tube body 40 is opened to recover the used pure water. At the same time, the lead powder deposited on the bottom of the shell 10 during the acid soaking process is also recovered with the reflux.

[0048] During the drying operation, the second tube body 40 is connected to the hot air inlet, and the first tube body 30 is connected to the exhaust duct. Hot air is introduced through the second tube body 40, and the hot air heats the electrode plates 50 in the device. At the same time, the moist air in the device is discharged through the first tube body 30, thereby achieving the effect of drying the electrode plates 50. The first tube body 30 can also collect the acid mist generated during the drying process. After the electrode plates 50 are dried, it is only necessary to stop injecting hot air from the second tube body 40.

[0049] The technical solution of the integrated acid dipping and curing device can be used for the acid dipping, rinsing, drying and storage processes of the electrode plate 50, which solves the problem of multiple stacking of the electrode plate 50 during the production process and improves the production efficiency of the electrode plate 50; at the same time, the device is convenient for collecting pure water and sulfuric acid when used in the acid dipping and rinsing processes, which is beneficial to the secondary utilization of resources and reduces material consumption. The rinsing process is changed from stacking and rinsing the electrode plates 50 to soaking, which greatly reduces the use of pure water. When used in the storage process, they can be stacked to reduce the space occupied; the setting of the tube body 2 40, after the cleaning of the electrode plate 50 is completed, the pure water is recovered and the inside of the device is cleaned, which reduces the cleaning frequency of the device; the setting of the tube body 1 30 is beneficial to the unified collection and treatment of acid mist in the acid dipping and drying processes.

At the same time, the length of the first screw 627 extending out of the first threaded hole 626 and the length of the threaded sleeve 629 extending out of the annular groove 628 can be set to be changeable to adapt to the different placement requirements of the gaps between the electrode plates 50.
