Description

Technical Field

[0001] The utility model belongs to the technical field of battery manufacturing, and particularly relates to an acid adding pot for lead-acid batteries. Background Art

[0002] During the production process of lead-acid batteries, acid addition is divided into two processes. One is for the semi-finished batteries assembled with cured plates after grooving. Before leaving the factory, electrolyte needs to be added to the batteries for the first charge and discharge. Since chemical reactions occur inside the batteries during the charge and discharge process, the electrolyte and acid mist will be discharged. To avoid such pollution, during the acid addition and charging process, single small pots are put on each acid addition port of the batteries, and air pipes are additionally inserted. After the charging is completed, the single small pots and air pipes are removed. In this way, four additional processes are added, increasing the workload, reducing work efficiency, and failing to avoid environmental pollution. The other is in-battery formation, that is, for the semi-finished batteries assembled with cured green plates. During in-battery formation, a certain amount of electrolyte needs to be added and formed within a specified number of days. During the formation process, oxygen is generated at the positive electrode and hydrogen is generated at the negative electrode. Currently, most manufacturers also use a connected pot, and air pipes are inserted into each acid addition port of the connected pot to discharge the gas. While discharging the gas, a large amount of acid mist and electrolyte will be carried out from the acid addition port, causing environmental pollution. Because the acid solution has strong corrosiveness and conductivity, it is also prone to cause fire accidents.

[0003] For example, the Chinese utility model patent with the publication number CN215377644U discloses an acid adding pot, which includes a housing. At least one acid adding chamber is arranged in the housing. A top cover is arranged on the housing at the top of each acid adding chamber, and an acid adding nozzle is arranged at the bottom of each acid adding chamber on the housing. An acid adding hole for placing an acid filtering sheet is arranged on the top cover, so as to achieve the purpose of adding acid solution to the lead-acid battery.

[0004] However, currently, the same type of acid adding pots cannot avoid the overflow of electrolyte from the acid addition port, and still cause problems of environmental pollution and electrolyte waste. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an acid adding pot for lead-acid batteries. By arranging a liquid collecting pot on the periphery of the multi-connected acid adding pot body, and at the same time, arranging a fence on the edge of the upper surface of the multi-connected acid adding pot body, the acid liquid overflowing to the upper surface of the multi-connected acid adding pot body from the acid addition port can flow into the liquid collecting pot, so as to solve the problems that a large amount of acid mist and electrolyte will be carried out from the acid addition port during the acid addition process of the existing acid adding pot, causing environmental pollution and being prone to cause fire accidents.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to an acid adding pot for lead-acid batteries, which comprises a multi-connected acid adding pot body and at least one liquid collecting pot arranged on the periphery of the multi-connected acid adding pot body; an acid adding port is arranged on the upper surface of the multi-connected acid adding pot body, a retaining wall is arranged on the edge of the upper surface of the multi-connected acid adding pot body, and the upper edge of the liquid collecting pot is not lower than the upper edge of the retaining wall; no retaining wall is arranged on the upper surface of the multi-connected acid adding pot body at the connection with the liquid collecting pot, so that the acid liquid overflowing from the acid adding port to the upper surface of the multi-connected acid adding pot body can flow into the liquid collecting pot.

[0008] As a preferred technical solution of the utility model, the lower end of the liquid collecting pot is higher than the lower end of the multi-connected acid adding pot body, so as to avoid interference when the lower end of the multi-connected acid adding pot body is inserted into the battery acid injection port.

[0009] As a preferred technical solution of the utility model, a liquid discharge port is arranged at the lower end of the liquid collecting pot, and a valve is arranged on the liquid discharge port.

[0010] As a preferred technical solution of the utility model, a guide plate is fixed on the inner wall of the liquid collecting pot, the guide plate is inclined, and the higher end of the guide plate is fixedly connected with the multi-connected acid adding pot body and is flush with the upper surface of the multi-connected acid adding pot body, so as to guide the acid liquid overflowing to the upper surface of the multi-connected acid adding pot body into the liquid collecting pot.

[0011] As a preferred technical solution of the utility model, a cover plate is fixed on the upper edge of the liquid collecting pot, so as to reduce the splashing of the acid liquid out of the liquid collecting pot during the process of the acid liquid falling into the liquid collecting pot, thereby avoiding environmental pollution.

[0012] As a preferred technical solution of the utility model, the liquid collecting pot is arranged at the end of the multi-connected acid adding pot body.

[0013] As a preferred technical solution of the utility model, two liquid collecting pots are adopted, and the two liquid collecting pots are symmetrically arranged at both ends of the multi-connected acid adding pot body, so as to balance the center of gravity of the whole acid adding pot and avoid the problem of acid liquid leakage caused by the skew of the acid adding pot.

[0014] The utility model has the following beneficial effects:

[0015] By arranging the liquid collecting pot on the periphery of the multi-connected acid adding pot body and arranging a retaining wall on the edge of the upper surface of the multi-connected acid adding pot body, the acid liquid overflowing from the acid adding port to the upper surface of the multi-connected acid adding pot body can flow into the liquid collecting pot, which not only avoids environmental pollution caused by the overflowing acid liquid, but also facilitates the recycling of the collected acid liquid and saves the raw material cost.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0028] In the description of the present utility model, it should be understood that terms such as "end", "upper", "lower", "side", "top", "bottom", "length", "inner", "surface", etc. indicating orientation or positional relationships are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0029] During the in-battery formation of the battery, a certain amount of acid solution, i.e., electrolyte, needs to be added and formed within a specified number of days. During the formation process, oxygen is generated at the positive electrode and hydrogen is generated at the negative electrode. Currently, most manufacturers use a connected pot to add acid from the battery acid injection port, and at the same time, air pipes are inserted into each acid addition port of the connected pot to discharge the gas. While discharging the gas, a large amount of acid mist and electrolyte will be carried out from the acid addition port, resulting in environmental pollution and material waste. Because the acid solution has strong corrosiveness and conductivity, it is also prone to causing fire accidents. Based on this, this embodiment provides an acid addition pot for lead-acid batteries. By providing a liquid collection pot on the circumferential side of the multi-connected acid addition pot body, the acid solution that overflows to the upper surface of the multi-connected acid addition pot body from the acid addition port can flow into the liquid collection pot, which not only avoids environmental pollution caused by the overflowing acid solution, but also facilitates the recycling and reuse of the collected acid solution, saving raw material costs.

[0030] Embodiment 1

[0031] Please refer to Figures 1 - 3 As shown, the acid addition pot for lead-acid batteries provided in this embodiment includes a multi-connected acid addition pot body 1 and a liquid collection pot 2 provided at the end of the multi-connected acid addition pot body 1. The upper surface of the multi-connected acid addition pot body 1 is provided with a plurality of acid addition ports 11. The edge of the upper surface of the multi-connected acid addition pot body 1 is provided with a retaining wall 3, and the height of the retaining wall 3 is set to 4 - 6 mm. The upper edge of the liquid collection pot 2 is flush with the upper edge of the retaining wall, and no retaining wall 3 is provided at the connection between the upper surface of the multi-connected acid addition pot body 1 and the liquid collection pot 2, so that the acid solution that overflows to the upper surface of the multi-connected acid addition pot body 1 from the acid addition port 11 can flow into the liquid collection pot 2. The lower end of the liquid collection pot 2 is higher than the lower end of the multi-connected acid addition pot body 1 to avoid interference at the lower end of the liquid collection pot 2 when the lower end of the multi-connected acid addition pot body 1 is inserted into the acid injection port of the storage battery.

[0032] In a preferred implementation manner of this embodiment, the lower end of the liquid collection pot 2 is provided with a liquid discharge port 21, and a valve 22 is provided on the liquid discharge port 21. After the acid addition is completed, the collected acid solution can be recycled and reused to save the amount of acid solution used and reduce production costs.

[0033] Embodiment 2

[0034] Based on Embodiment 1, the improvement of Embodiment 2 lies in:

[0035] Please refer to Figures 4 - 6As shown in the figure, a flow guide plate 23 is fixed to the inner wall of the liquid collecting pot 2. The flow guide plate 23 is inclined. The higher end of the flow guide plate 23 is fixedly connected to the multi-connected acid adding pot body 1 and is flush with the upper surface of the multi-connected acid adding pot body 1, so as to guide the acid liquid overflowing onto the upper surface of the multi-connected acid adding pot body 1 into the liquid collecting pot 2. At the same time, a cover plate 24 is fixed to the upper edge of the liquid collecting pot 2. Since the height of the liquid collecting pot 2 is limited, during the process of the acid liquid flowing into the liquid collecting pot 2, it will impact the inner wall and the bottom surface of the liquid collecting pot 2, and splashing is likely to occur. The setting of the cover plate 24 can effectively avoid this problem.

[0036] Embodiment 3

[0037] Based on Embodiment 2, the improvement in Embodiment 3 lies in:

[0038] Please refer to Figure 7 As shown in the figure, two liquid collecting pots 2 are used. The two liquid collecting pots 2 are symmetrically arranged at both ends of the multi-connected acid adding pot body 1. The acid liquid overflowing from the acid adding port 11 will flow into the liquid collecting pots 2 at both ends, so as to balance the center of gravity of the entire acid adding pot and avoid the problem of acid liquid leakage caused by the skew of the acid adding pot.
