Description

Technical Field

[0001] The utility model belongs to the technical field of valve-controlled lead-acid batteries, and in particular relates to a fast and accurate acid-adding tool for valve-controlled lead-acid batteries. Background Art

[0002] When adding acid to a valve-regulated lead-acid battery, the required amount of sulfuric acid is first set in the dosing cylinder, and then it passes through the transition cylinder to reach the inside of the battery. Figure 1 As shown, the current acid adding machine has two plastic tubes in the quantitative cylinder 1, one of which is a white plastic tube with a diameter of 3 cm, which is the acid inlet pipe 2, and the other plastic tube with a diameter of 2 cm, which is the acid return pipe 3. The bottom of the quantitative cylinder 1 is provided with a pipe and a switch connected to the transition cylinder. When the battery acid is added, the acid pump is started, and the sulfuric acid in the acid storage tank is added through the acid inlet pipe 2. When the required acid amount is reached, the acid addition is stopped, and the excess acid flows back to the acid storage tank through the acid return pipe 3. It takes 50 seconds from the acid addition to the acid return to the acid addition weight of one battery.

[0003] In addition, since the acid inlet pipe 2 and the acid return pipe 3 are relatively thin, the pipes are often blocked, affecting the acid inlet and acid return, which directly leads to the battery acid adding weight being too high or too light. The battery will be scrapped if the acid amount is too light, and the consistency between battery cells or battery packs will be affected if the acid amount is too heavy. Summary of the invention

[0018] The embodiments of the utility model are further described below in conjunction with the accompanying drawings.

[0019] like Figure 2 As shown, an embodiment of the utility model of a valve-controlled lead-acid battery fast and accurate acid adding tool is composed of a metering cylinder 1, an acid inlet pipe 5, an acid return pipe 7, a piston 4 and a turnover box 6. Among them, the metering cylinder 1 is the same as the existing metering cylinder, and a pipeline and a switch connected to the transition cylinder are still provided at the bottom. The metering cylinder 1 is cylindrical with an inner diameter of 15 cm.

[0020] The turnover box 6 is a square box with an open top. The dosing cylinder 1 is arranged in the turnover box, and the bottom surface of the dosing cylinder is fixedly connected with the bottom surface of the turnover box, or the bottom surface of the dosing cylinder and the bottom surface of the turnover box form a complete bottom surface.

[0021] The piston 4 is composed of a cylindrical piston body and a piston rod connected to the piston body. The piston rod is cylindrical and located at the center of the piston body. The upper end of the piston rod is fixed on the acid adding machine through a fixed rod (not shown in the figure). The outer diameter of the piston 4 is 12 cm, which is smaller than the inner diameter of the quantitative cylinder 1. An acid liquid channel is formed between the piston 4 and the quantitative cylinder 1. The diameter of the piston rod is 4 cm. The volume of the quantitative cylinder 1 is certain. The piston body of the piston 4 is completely located in the quantitative cylinder 1. With the difference in depth, the volume of the piston body remains unchanged, and the volume of the piston rod located in the quantitative cylinder 1 is different. The volume of the quantitative cylinder 1 minus the sum of the volume of the piston body and the piston rod located in the quantitative cylinder 1 is the volume of the set acid addition amount. The piston 4 has a certain effect of adjusting the volume of the acid addition amount. If the volume of the acid addition amount differs greatly, the volume of the acid addition amount can be determined by adjusting the depth of the piston 4 inserted into the quantitative cylinder 1.

[0022] Each quantitative cylinder 1 is equipped with an acid inlet pipe 5, the voltage of the lead-acid battery is conventionally 12V, and the voltage of each single cell is 2V, that is, there are 6 single cells, and there are 6 quantitative cylinders 1 of such a structure. The acid outlet of the acid inlet pipe 5 is located in the upper port of the quantitative cylinder 1, and the inner diameter of the acid inlet pipe 5 is 6cm.

[0023] There is one acid return pipe 7, with an inner diameter of 8 cm, which is arranged on the bottom surface of the turnover box 6. There can also be multiple acid return pipes 7, such as 2-3.

[0024] The utility model acid adding tool completely removes the acid inlet pipe 2 and the acid return pipe 3 in the current quantitative cylinder 1 of the acid adding machine, and processes a piston 4 with a diameter of 12 cm on the basis of the current quantitative cylinder diameter of 15 cm, and places it in each quantitative cylinder. Before adding acid to the battery, the acid addition amount required by the battery is set on the control panel of the acid adding machine, and the acid pump is started. The piston 4 is fixed to the position of the acid addition amount required by the battery. After the acid addition is completed, the excess acid directly flows back to the turnover box 6, and finally flows back to the acid storage tank through the acid return pipe 7. During the battery acid adding process, the position of the piston 4 relative to the quantitative cylinder 1 does not move. Because the battery model is different, the battery acid addition amount is different, so the position of the piston 4 relative to the insertion depth of the quantitative cylinder 1 is only adjusted when the battery model is changed.

[0025] Therefore, before adding acid to the battery, the volume of the piston is determined according to the acid addition amount required by the battery and the volume of the metering cylinder, that is, the volume of the metering cylinder minus the volume of the piston is equal to the volume of the acid addition amount. The piston is installed in the metering cylinder, and then the acid addition amount required by the battery can be set on the control panel of the acid adding machine, and the sulfuric acid in the acid storage tank directly enters the metering cylinder 1 through the acid inlet pipe 5. Due to the increase in the diameter of the acid inlet pipe 5 and the acid return pipe 7, the time required for one battery to add acid to return acid and determine the acid addition weight is greatly reduced, only 15s, saving 35s, and the production efficiency is increased by 70%, and the acid inlet pipe 5 and the acid return pipe 7 will not be blocked, and the weight consistency of the battery after acid addition is better.
