Description

Technical Field

[0001] The utility model relates to the technical field of storage batteries, in particular to an anti-skew adjustable acid-adding kettle. Background Art

[0002] There is an acid-adding process in the production of lead-acid batteries. An acid-adding pot needs to be installed on the semi-finished lead-acid battery. The acid-adding pot connects the battery and the acid-adding machine. The acid-adding machine exhausts the gas inside the battery by vacuuming and injects the electrolyte into the battery under negative vacuum. Since excessive electrolyte will be added during the acid-adding process, part of the excess electrolyte will accumulate in the acid-adding pot in the next formation process. Therefore, the acid-adding pot is an indispensable tool in the acid-adding and formation processes of lead-acid battery production.

[0003] The existing acid adding pot is generally directly connected to the acid filling port of the battery through the acid outlet nozzle at the bottom, such as Chinese patent CN202210883080.4, patent name: an acid-overflow-proof acid adding pot, Chinese patent CN201310116856.0, patent name: a tube-free battery acid adding pot group. After the docking of such acid adding pots is completed, a glue nozzle is set on the acid outlet nozzle and the acid filling port to prevent acid leakage. However, the acid outlet nozzle of the acid adding pot is prone to tilt when docking with the battery outlet. After tilting, the glue nozzle will have poor sealing performance and the acid will leak easily, resulting in less acid in quantitative acid addition, affecting the quality of the battery. Utility Model Content

[0004] The utility model aims to provide an anti-skew adjustable acid adding pot, which can prevent the acid adding pot from being skewed when it is docked with the acid adding hole of the battery, reduce the possibility of acid leakage caused by decreased sealing due to the skew, and improve the stability of acid adding and the quality of the battery.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an anti-skew adjustable acid-adding pot, comprising a pot body, the top of the pot body has an acid-adding port, the bottom of the pot body has an acid-discharging nozzle, and the bottom of the pot body is provided with at least three adjustment feet at intervals around the acid-discharging nozzle.

[0006] A further improvement of the present utility model is that the adjusting foot comprises a base column arranged at the bottom of the kettle body, and a support column is threadedly connected to the lower end of the base column.

[0007] A further improvement of the utility model is that the lower end surface of the base column is higher than the lower end surface of the acid outlet nozzle.

[0008] A further improvement of the present invention is that a cushion block is provided at the bottom of the support column.

[0009] A further improvement of the utility model is that four adjusting feet are provided and are arranged at intervals along the circumferential center of the acid outlet nozzle.

[0010] A further improvement of the utility model is that the upper part of the kettle body is cylindrical, and the lower part forms a bell mouth, and the lower end of the bell mouth is connected to the acid outlet.

[0011] A further improvement of the present invention is that a level is provided on the top of the kettle body.

[0012] A further improvement of the utility model is that the outer periphery of the acid outlet nozzle is connected with a glue nozzle by interference fit.

[0013] The beneficial effects of the utility model are:

[0014] The utility model provides an adjusting foot on the kettle body so as to assist the acid adding kettle to stand upright when the acid adding kettle is connected to the acid adding hole of the battery, thereby preventing the acid adding kettle from shaking and tilting during the acid adding process, reducing the possibility of acid leakage caused by decreased sealing due to tilting, and improving the stability of acid adding and the quality of the battery.

[0015] The utility model is provided with at least three adjusting feet, and the multiple adjusting feet can improve the stability of the acid adding pot, and the length of the adjusting feet can be adjusted according to needs, so as to adapt to storage batteries with different acid injection nozzle heights.

[0016] Different battery shells on the market currently have different height differences around the acid filling ports, and fixed-length pads are difficult to use. The utility model can adjust multiple adjustment pads so that each adjustment pad adapts to the corresponding height difference, further improving the scope of application and the stability of the acid filling pot.

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1: Combination Figures 1 to 4 It can be known that an anti-skew adjustable acid-adding kettle includes a kettle body 1, the top of the kettle body 1 has an acid-adding port 2, the bottom has an acid-discharging nozzle 3, and the bottom of the kettle body 1 is provided with at least three adjustment feet at intervals around the acid-discharging nozzle 3.

[0024] The adjusting foot comprises a base column 4 arranged at the bottom of the kettle body 1, and a support column 5 is threadedly connected to the lower end of the base column 4.

[0025] The lower end surface of the base column 4 is higher than the lower end surface of the acid outlet nozzle 3. A cushion block 6 is provided at the bottom of the support column 5. The cross-sectional size of the cushion block 6 is larger than the cross-sectional size of the support column 5, which increases the contact area with the battery, thereby improving the stability of the acid adding pot.
