Vacuum acid filling device for AGM battery

Abstract

An AGM battery vacuum acid filling device comprises an acid storage container, a junction station and an acid measuring container, the top of the junction station is connected with the acid storage container through a circulation pipeline, a switch valve and an adjusting valve are arranged on the circulation pipeline, an outlet of the junction station is connected with an acid filling hole of theacid measuring container through a filling pipeline, and the junction station is connected with a vacuum pump. A weighing sensor is arranged at the bottom of the acid measuring container, the junctionstation is hermetically connected with an acid injection hole of the acid measuring container through a sealing seat, the sealing seat comprises a seat body and a liquid sealing cover, a bottom outlet of the seat body is hermetically connected with the acid injection hole of the acid measuring container, an annular groove is formed around a top inlet of the seat body, liquid is contained in the groove, and the liquid sealing cover is inversely buckled in the groove. A connecting hole is formed in the top end of the liquid sealing cover; the filling pipeline penetrates through the connecting hole and extends into the acid measuring container. According to the sealing seat, the junction station is connected with the acid measuring container in a liquid sealing mode, the weighing sensor is used for weighing the weight of acid liquid in the acid measuring container, and weighing is more accurate.

Description

technical field [0001] The invention relates to a vacuum acid filling device for AGM batteries, which belongs to the technical field of storage batteries. Background technique [0002] AGM batteries are widely used in automobile start-stop systems due to their excellent characteristics such as maintenance-free and long life. The AGM battery adopts a lean liquid design, the separator is made of ultra-fine glass fiber, and the pole group is tightly assembled. Compared with the battery of the same specification, the cycle life of the AGM battery is three times that of the ordinary lead-acid battery, and it has a longer service life. . As the starting battery of automobiles, AGM battery has high requirements on its starting performance and service life, and the precise control of the amount of acid per cell in the process of preparing the battery has a crucial impact on these performances. [0003] Due to the structural design of the liquid injection hole, the existing method ...

AI Technical Summary

Problems solved by technology

[0003] Due to the structural design of the liquid injection hole, the existing method for measuring the amount of acid injection cannot perform vacuuming operations, and the acid can only be manually released on the equipment, which makes the measured acid amount of a single cell and the actual production of acid injection amount very different. error

Moreover, the existing acid filling device is fixed on the acid filling workbench through a fixing frame, so it is impossible to carry out real-time weighing of the amount of acid filling in the battery
