Description

Sealed acid pressing device for storage battery formation

technical field

The utility model relates to a negative pressure acid pressing device for the internal formation of lead-acid storage batteries, which is an acid pressing device used in the formation process of lead-acid storage batteries.

Background technique

During the static stage of the internal formation of the lead-acid battery, the acid in the rich liquid pot needs to be hydraulically returned to the battery cell to improve the formation efficiency and battery consistency. At present, the method of pressing acid by most manufacturers is to use a rubber ball to block the upper mouth of the rich liquid pot, press the rubber ball to pressurize the acid liquid, and press it into the battery; It's inefficient and doesn't press acid very well.

Contents of the invention

The purpose of the utility model is to provide a negative-pressure acid pressing device for battery formation, which can carry out negative-pressure acid pressing on six cells of the battery at one time, can effectively improve the formation efficiency, and improve the consistency of the battery.

The sealed acid pressing device for battery formation includes an acid solution tank, which is divided into multiple acid solution chambers. The number and layout of the acid solution chambers correspond to the single cells of the battery; the height of the partitions between the acid solution chambers is low. At the height of the tank wall, the bottom of each acid solution chamber is provided with an acid outlet for injecting acid into the battery; the upper opening of the acid solution tank is equipped with a sealing cover, and the sealing cover is provided with a vacuum pumping interface and an air valve.

A sealing gasket is arranged between the sealing cover and the notch of the acid solution tank.

This device is used in the static stage of storage battery formation. Put the sealing cover on the upper part of the acid solution tank, and seal it with a sealing gasket installed between the sealing cover and the notch of the acid solution tank. Close the air valve, use a vacuum pump to evacuate from the air extraction port of the valve cover, a certain negative pressure is formed in the acid tank and the battery, then open the air valve, the outside air enters the acid tank, and the acid tank and battery are used The pressure difference makes the acid liquid in the tank be automatically pressed into the battery, and this is repeated 2-3 times, that is, the formation is completed.

To sum up, this device creates a negative pressure in the formation system by extracting a vacuum, and then connects the acid tank to the atmosphere. The acid tank eliminates the vacuum and creates a pressure difference with the battery, thereby smoothly hydraulically pumping the acid into the battery. The operation is simple, and the acid can be pressed on each cell of the battery at the same time, which greatly speeds up the acid pressing speed during the standing period, improves the formation work efficiency, and fully forms the battery.

Description of drawings

Fig. 1 is a structural schematic diagram of an embodiment of the acid pressing device of the present invention, and the figure also shows the connection relationship between the acid pressing device and each cell of the storage battery when injecting acid.

Fig. 2 is a sectional view along A-A of Fig. 1 .

In the figure, 1-vacuum port, 2-air valve, 3-sealing cover, 4-acid tank, 4-1-partition, 4-2-acid chamber, 4-3-acid outlet, 5-battery , 6-Sealing ring.

Detailed ways

The embodiment structure of the acid pressing device of the present utility model is shown in Fig. 1 and Fig. 2, and Fig. 1 shows that the acid liquid tank 4 is divided into a plurality of acid liquid chambers 4, as can be seen from Fig. 2, each acid liquid in the acid liquid tank 4 The chambers are double rows with a total of six chambers (it can also be divided into a single row with a total of six chambers, the number and distribution pattern of the acid chambers correspond to the pattern of each compartment in the storage battery to be formed), and the bottom of each chamber is equipped with an acid outlet 4-3. As can be seen from Fig. 1, the height of the partition 4-1 is lower than the tank wall of the acid solution tank 4, a sealing ring 6 is arranged between the sealing cover 3 and the notch of the acid solution tank 4, and an air valve 2 is arranged on the sealing cover 3 and vacuum port 1. Fig. 1 shows, when injecting acid, each acid outlet 4-3 of this device is connected with the acid injection mouth of each compartment of storage battery 5 correspondingly.

During formation, when the interface 1 is evacuated by the vacuum pump, the acid liquid is concentrated in the acid liquid tank 4, negative pressure is generated in each cell of the battery 5, and the gas valve 2 is closed at the same time. When the vacuum suction is stopped, the gas valve 2 is opened, and the outside air enters the acid tank, forming a pressure difference with each cell of the accumulator 5, and the acid solution is easily pressed into the accumulator in a negative pressure state. Repeat the operation in this way, when vacuuming, the acid solution in the battery 5 is sucked into the acid solution tank 4, and when the vacuum in the acid solution tank is eliminated, the acid solution is pressed into the battery, and after 2-3 times, the acid solution can be fully Penetrates the electrodes and fills the battery. To achieve the purpose of full formation.
