Description

Technical Field

[0001] The present application relates to a lead-acid battery, and in particular to a quantitative acid-free liquid injection device for a lead-acid battery. Background Art

[0002] like Figure 1 As shown, when the lead-acid battery filling machine is quantitative, the excess acid flows back to the acid storage tank below. The acid in the acid storage tanks of multiple filling machines in one area is pumped back to the front cold acid barrel through the same pneumatic diaphragm pump. After the acid is cooled, it is supplied to the filling machine for use.

[0003] Obvious disadvantages of existing technology:

[0004] 1. The acid storage box under the lead-acid battery filling machine is not a closed structure, and acid mist will remain in the surrounding environment after a long time.

[0005] 2. The temperature of the acid in the acid storage tank below the lead-acid battery filling machine will rise, and it needs to be cooled by a cold acid machine before being supplied to the filling machine, which increases energy consumption.

[0006] 3. The operation of the pneumatic diaphragm pump will generate a lot of noise, causing pollution to the production site environment. Utility Model Content

[0007] The utility model aims to provide a quantitative acid-free device for a lead-acid battery liquid injection machine. In order to optimize the production process, reduce environmental pollution and reduce energy consumption, the utility model combines theory with experiment to provide a special technical solution.

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0009] The embodiment of the present application discloses a quantitative acid-free device for a lead-acid battery liquid injection machine, which includes an acid supply pipeline interface, an acid inlet manual valve, an acid inlet valve, an acid discharge valve, a magnetically driven pump, and a one-way check valve that are sequentially connected along the pipeline. The end of the one-way check valve that is away from the magnetically driven pump is connected between the acid inlet manual valve and the acid inlet valve. The acid inlet valve and the acid discharge valve are connected to the liquid injection pipeline via a four-way interface, and the liquid injection pipeline is connected to a volumetric quantitative cup.

[0010] Preferably, in the above-mentioned quantitative acid-free device for the lead-acid battery liquid injection machine, the acid discharge pipeline between the acid discharge valve and the magnetic drive pump is a hose.

[0011] Preferably, in the above-mentioned quantitative acid-free device for the lead-acid battery liquid injection machine, a three-way interface is also included, and the three-way interface is respectively connected to the acid inlet manual valve, the acid inlet valve and the one-way check valve through pipelines.

[0012] Compared with the prior art, the advantages of this technical solution are that the acid storage box and pneumatic diaphragm pump under the lead-acid battery injection machine are eliminated, and the quantitative excess acid is pumped into the acid supply pipeline through a magnetic pump (a check valve is installed in the pipeline to prevent acid reflux). All pipelines are sealed mechanisms, and no acid mist enters the surrounding environment. The quantitative excess acid directly enters the acid supply pipeline, and the acid temperature does not change much, and there is no need to return to the cold acid barrel for cooling, which reduces energy consumption.

[0019] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application.
