Description

Technical Field

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

[0002] The main structure of a lead-acid battery generally includes a battery cell and a battery cover. During the processing of the battery, acidic electrolyte needs to be added to the battery housing in a quantitative flooded manner. Among them, when using an acid adding pot group to add acid to the battery, a large amount of heat will be generated, causing the electrolyte to heat up rapidly or even boil, which will cause the acidic electrolyte to splash out from the acid adding hole. When adding acid to the acid adding pot, the acidic liquid may also overflow due to too fast acid addition or the tilting of the acid adding pot. And during the subsequent formation process, under the action of the gas pressure generated during the battery formation process, the electrolyte is likely to overflow from the acid adding hole, causing damage to the appearance of the battery, corrosion of the connection terminals, waste of electrolyte, corrosion of the surrounding environment, and personal injury.

[0003] Chinese patent "An acid adding pot for battery acid injection", publication number: CN203377325U; this patent discloses an acid adding pot for battery acid injection, including a pot cover. A groove is provided on the top surface of the pot cover, and an acid injection hole is provided at the bottom of the groove. The side wall of the groove gradually converges from the top surface of the pot cover to the acid injection hole. The groove is in the shape of an inverted frustum of a cone, and the included angle between the side wall of the groove and the top surface of the pot cover is an acute angle. Compared with the prior art, the side wall of the groove on the top surface of the pot cover of the acid adding pot for battery acid injection of the utility model gradually converges from the top surface of the pot cover to the acid injection hole, forming an inclined surface above the acid injection hole, which not only facilitates the rubber interface of the vacuum acid injection machine to slide into the acid injection hole along the side wall of the groove, but also is beneficial for the electrolyte dripping from the rubber interface to flow into the acid adding pot through the side wall of the groove and the acid injection hole, without causing corrosion to the acid adding pot or the battery. Among them, due to the relatively shallow groove of this patent, if the acid liquid flow rate is too fast during acid addition and it cannot enter the acid pot in time, the acid liquid is likely to overflow and contaminate the top surface of the cover body.

[0004] Aiming at the problems of easy acid overflow and acid splashing during acid addition of the above-mentioned acid adding pot for batteries, the utility model designs an anti-overflow acid adding device for lead-acid batteries. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-overflow acid adding device for lead-acid batteries. Through the design and function of the anti-overflow mechanism and the ventilation channel, the acid liquid discharged when the acid adding pot is filled can be converged and flow into the acid storage device, and at the same time, the situation of acid splashing at the acid adding interface caused by the rapid entry of the acid liquid into the interior of the acid adding pot is avoided, solving the problems of easy acid overflow and acid splashing pointed out above.

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

[0007] The utility model relates to an anti-overflow acid adding device for lead-acid batteries, which includes a battery, an acid adding pot, and an anti-overflow mechanism. An acid adding pot is assembled on the acid injection hole of the battery. The acid adding pot includes a spout, a pot body, and a pot cover. The spout, the pot body, and the pot cover are of an integrated structure. An acid adding interface is provided on the top surface of the pot cover, and an acid adding pipe is assembled on the inner wall of the acid adding interface. A ventilation channel is provided inside the acid adding interface. The acid adding pot is assembled with an anti-overflow mechanism at the acid adding interface. The anti-overflow mechanism includes an anti-overflow groove, an acid liquid channel, and an acid storage device. The circumferential side of the anti-overflow groove is fixedly communicated with the acid liquid channel, and the acid liquid channel is communicated with the acid storage device. The ventilation channel can timely discharge the gas inside the acid adding pot to ensure the smooth entry of the acid liquid inside the acid adding pot. And the ventilation channel changes the vertical upward exhaust direction at the acid adding interface to a horizontal direction and a direction slightly above the horizontal. At the same time, due to the function of the ventilation channel, the inner wall size of the acid adding interface can match the outer wall size of the acid adding pipe, which also greatly avoids the situation of acid liquid splashing out from the acid adding interface. At the same time, if the amount of acid added inside the acid adding pipe exceeds, the ventilation channel can also timely act as an acid liquid discharge channel to ensure the smooth discharge of the acid liquid without splashing, as well as avoid corroding the equipment and causing personal injury.

[0008] As a preferred technical solution of the utility model, a splash-proof cap is fixed above the acid adding interface of the acid adding pipe. The splash-proof cap is of a cylindrical structure, and the acid adding pipe penetrates through the inner top wall of the splash-proof cap. The splash-proof cap is used to prevent the splashing acid liquid generated when the acid liquid is quickly discharged from the acid adding interface and the ventilation channel, and also plays a protective role to avoid the acid liquid splashing onto external equipment and personnel and causing harm.

[0009] As a preferred technical solution of the utility model, the ventilation channel penetrates through the bottom of the outer wall of the acid adding interface, and the ventilation channels are distributed in a circumferential array. The outer port of the ventilation channel is located inside the splash-proof cap. The outer port of the ventilation channel is located below the acid liquid channel.

[0010] As a preferred technical solution of the utility model, the acid storage device includes an acid storage pipe and a connecting pipe. A drain port is provided on the connecting pipe.

[0011] As a preferred technical solution of the utility model, one connecting pipe is fixedly communicated with the bottom of each of several acid storage pipes.

[0012] As a preferred technical solution of the utility model, several pipe sleeves are provided on the upper surface of the connecting pipe, and the bottom of the acid storage pipe is in sliding fit with the inner wall of the pipe sleeve. The sliding assembly method of the acid storage pipe and the pipe sleeve is beneficial to the convenience and flexibility of disassembly and installation.

[0013] As a preferred technical solution of the present utility model, a storage acid pipe is slidably fitted to the outer end of the acid liquid channel, and the outer end of the acid liquid channel penetrates through the storage acid pipe and extends into the interior of the storage acid pipe; the purpose is to avoid the overflow of acid liquid from the connection between the storage acid pipe and the acid liquid channel when the acid liquid channel and the storage acid pipe are assembled in a sliding fit manner.

[0014] As a preferred technical solution of the present utility model, the outer end of the acid liquid channel is fixedly connected to a storage acid pipe.

[0015] The present utility model has the following beneficial effects:

[0016] 1. Through the design and function of the anti-overflow mechanism and the air-permeable channel, the present utility model ensures the smooth entry of the acid liquid inside the acid adding pot, enables the gas inside the acid adding pot to be discharged in a timely manner and changes the exhaust direction, has the advantages of converging the acid liquid filled and discharged in the acid adding pot, and at the same time avoiding the splashing of the acid liquid from the acid adding interface to cause corrosion and pollution.
