Description

Technical Field

[0001] This utility model belongs to the field of battery acid extraction technology, and particularly relates to an acid extraction device for storage batteries. Background Technology

[0002] Lead-acid batteries, with their high safety, cost-effectiveness, high quality, stability, reliability, and unique recyclability, have become an indispensable basic product in the national economy. With advancements in industry technology and external economic development and technological progress, market demand and application scenarios are gradually increasing. Currently, they are mainly used as backup power batteries in communications, power, automatic control, and emergency equipment; energy storage batteries for new energy sources such as wind and solar power; starting and lighting batteries for automobiles, motorcycles, and internal combustion engines; and power batteries for electric bicycles, low-speed electric vehicles, and special electric vehicles. Due to their inexpensive materials, simple manufacturing process, mature technology, low self-discharge, and maintenance-free operation, the application range of lead-acid batteries will continue to expand, giving rise to demands from more new industries.

[0003] The battery charging and formation process includes a step called negative pressure acid extraction. The battery charging and formation process involves multiple reactions between lead dioxide and lead sulfate, and between metallic lead and lead sulfate. To ensure smooth chemical reactions during charging and discharging, a sufficient amount of acid is added during the acid addition process. The acid extraction step removes excess acid. The existing acid extraction process uses a negative pressure system. A conduit connected to the negative pressure system is inserted into the battery acid reservoir and the battery valve seat hole, and the acid is extracted. However, using conduits requires workers to manually control the distance between the tips of each conduit before inserting them into the corresponding battery acid reservoir and battery valve seat hole. Manual distance control is inefficient and affects production efficiency. Utility Model Content

The acid extraction mechanism includes a fixing plate with several fixing holes. An elastic sleeve is installed inside the fixing holes. An acid extraction tube is fitted inside the inner ring of the elastic sleeve. One end of the acid extraction tube is connected to a flexible tube, and the other end is inserted into the acid injection vessel and extends into the interior of the storage battery body. A negative pressure pump is connected to the end of the flexible tube away from the acid extraction tube.

[0016] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] Example

[0018] like Figure 1As shown, the acid extraction device for a storage battery includes a storage battery body 10, an acid injection tank 20, and an acid extraction mechanism 30 arranged sequentially from bottom to top. The acid extraction mechanism 30 includes a fixing plate 31 with several fixing holes. An elastic sleeve 32 is provided inside the fixing holes. An acid extraction tube 33 is fitted inside the inner ring of the elastic sleeve 32. One end of the acid extraction tube 33 is connected to a flexible tube 34, and the other end is inserted into the acid injection tank 20 and extends into the interior of the storage battery body 10. The end of the flexible tube 34 away from the acid extraction tube 33 is connected to a negative pressure pump.

[0019] Specifically, the fixing plate 31 is modified from the old battery cover of the same specification battery body 10. The elastic sleeve 32 is made of rubber material, but is not limited to rubber material, to increase the friction between the acid extraction tube 33 and the fixing plate 31, so that it can be stably fixed on the fixing plate 31. The employee can hold a fixing plate 31 and insert several acid extraction tubes 33 into the corresponding acid injection tank 20 at the same time, and extend them into the inside of the battery body 10. Then, the negative pressure pump can be started to remove the acid remaining in the acid injection tank 20. This not only makes the operation simple, but also improves the acid extraction efficiency.

[0020] like Figure 1 As shown, the battery body 10 and the acid filling pot 20 are respectively provided with a liquid filling hole and a pot opening on the side close to each other. The pot opening is connected to the liquid filling hole. The side of the acid filling pot 20 away from the battery body 10 is provided with an acid extraction hole 21. The liquid filling hole, the pot opening, the acid extraction hole 21 and the acid extraction tube 33 are all located on the same axis, which makes it convenient for the acid extraction tube 33 to directly penetrate the acid filling pot 20 and enter the interior of the battery body 10.

[0021] like Figure 1 and Figure 2 As shown, a deflection prevention plate 35 is provided below the fixed plate 31 and is movably sleeved on the outer ring of the acid extraction tube 33. A spring-loaded assembly 36 is connected between the deflection prevention plate 35 and the fixed plate 31.

[0022] Specifically, by setting an anti-deviation plate 35, the stability of the tail ends of several acid extraction tubes 33 is increased, so that they will not deviate before being inserted into the acid injection pot 20, which would cause them to fail to align with the acid extraction hole 21. After the acid extraction is completed, the acid extraction tube 33 is pulled out, and the anti-deviation plate 35 can be automatically reset by the spring-loaded component 36.

[0023] like Figure 1 and Figure 2 As shown, the rebound assembly 36 includes a sleeve 361. One end of the sleeve 361 is fixedly connected to the anti-deviation plate 35, and the other end is provided with a guide hole 362. A sleeve rod 363 is movably sleeved on the inner ring of the guide hole 362. One end of the sleeve rod 363 is fixedly connected to the fixing plate 31, and the other end is fixedly connected to a return spring 365. The end of the return spring 365 away from the sleeve rod 363 is fixedly connected to the inner wall of the sleeve 361.

[0024] Specifically, through the force of the return spring 365, the sleeve rod 363 will be pushed away from the inside of the sleeve 361 without any external force, causing the fixing plate 31 and the anti-deviation plate 35 to move away from each other.

[0025] like Figure 2 As shown, the outer ring of the sleeve 363 is fixedly fitted with an anti-detachment baffle 364. The anti-detachment baffle 364 is located inside the sleeve 361, and the outer ring diameter of the anti-detachment baffle 364 is larger than the inner ring diameter of the guide hole 362.

[0026] Specifically, the anti-detachment baffle 364 can prevent the sleeve rod 363 from separating from the sleeve 361, and prevent the anti-deviation plate 35 from falling directly off the acid extraction tube 33.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
