An acid injection device for storage battery

Abstract

The invention provides an acid filling device of a storage battery and relates to the field of industrial devices. The tops of supporting legs are fixedly connected to a table plate, the top of the table plate is fixedly connected to a base, a first casing pipe is fixedly connected to the back surface of the table plate, a first spring is fixedly connected to the inner wall of the first casing pipe, a first conveying pipe is arranged in the first casing pipe and is located at the inner ring of the first spring, a pressing valve is fixedly connected to the top of the first conveying pipe, and a second spring is fixedly connected to the interior of the pressing valve. The base is arranged below a branch pipe and can position a storage battery. When a third casing pipe is pressed, a pressing valve in the third casing pipe can be opened and the branch pipe is inserted into an acid filling hole of the storage battery and when the third casing pipe is released, acid filling is stopped. The acid filling device greatly improves storage battery acid filling convenience. Through simultaneous injection of multiple branch flows, an acid filling rate is greatly improved.

Description

technical field [0001] The invention relates to the technical field of industrial equipment, in particular to an acid injection device for storage batteries. Background technique [0002] The application fields of batteries are very extensive. According to different uses, they can be divided into different types such as backup for communication, traction power, and starting. Traction batteries are mainly used as power sources for electric forklifts and engineering vehicles. At present, their main The way of formation is water bath formation or plate formation. [0003] The currently used lead-acid battery acid injection machine is mainly composed of a vacuum system, an acid pump, an acid liquid buffer tank, an acid injection tank, and an acid injection nozzle. The structure is relatively large and the measurement adjustment is inconvenient. [0004] At present, during the production and processing of batteries, one of the procedures is to add acid. The amount of acid added ...

[0003] The currently used lead-acid battery acid injection machine is mainly composed of a vacuum system, an acid pump, an acid liquid buffer tank, an acid injection tank, and an acid injection nozzle. The structure is relatively large, and the measurement and adjustment are inconvenient.

[0004] At present, in the process of battery production and processing, one of the procedures is to add acid. The amount of acid added to each battery cell is the same as that of other cells. The difference in the amount of acid added will affect the use of the battery.
