Acid adding cylinder of acid adding machine and acid concentration measuring method of acid adding cylinder

Abstract

The invention relates to the field of storage battery production equipment, in particular to an acid adding cylinder of an acid adding machine. The acid adding cylinder is hollow and used for storing acid liquid. The acid adding cylinder is provided with a measuring device for detecting the concentration and temperature of the acid liquid stored in the acid adding cylinder. The acid adding cylinder has the advantages that the acid adding cylinder is simple in structure and convenient to use, the density of dilute sulfuric acid for being added into a storage battery can be measured fast during acid adding, the density of the sulfuric acid can be measured conveniently and fast, measuring and monitoring frequency is increased while acid adding efficiency is unaffected, an operator does not need to contact with the sulfuric acid in the whole density measuring process, personal accidents and equipment corrosion risk are avoided, and the device is low in cost.

Description

technical field [0001] The invention relates to the field of storage battery production equipment, in particular to an acid adding tank of an acid adding machine and a method for measuring acid concentration in the acid adding tank. Background technique [0002] Lead-acid batteries (hereinafter referred to as batteries) are mainly composed of five parts: plate, separator, sulfuric acid, battery tank / cover, and terminals. The sulfuric acid solution is not only the electrolyte of the battery, but also participates in electrode reactions and battery reactions, and is also an active substance. Therefore, sulfuric acid is one of the key raw materials to be controlled in the battery production process, and its density is one of the important parameters of sulfuric acid control. The fluctuation of sulfuric acid density will directly affect the performance and consistency of the battery, including battery internal resistance and open circuit voltage. , battery capacity, battery life...

AI Technical Summary

Problems solved by technology

[0004] ①The measurement frequency is limited, and it cannot be monitored all the time. Generally, it is the first article inspection, and the process is randomly inspected every 4 hours;

[0005] ②The operation is inconvenient. It is necessary to rinse the measuring cup first, then go to the acid tank to pour the acid into the measuring cylinder, and return the acid solution to the tank after measurement and other tedious actions;

[0006] ③ The measurement time is long, and the acid addition action needs to be stopped when measuring the density. It takes at least 2 minutes to measure the acid density once;

[0007] ④ Risk of personal accidents and equipment corrosion. Acid liquid is corrosive, frequent acid pouring and acid pouring are easy to drip, and there are risks of personal accidents and equipment corrosion;

[0008] ⑤ It is difficult to manage measuring instruments, especially glass instruments such as thermometers and density meters are easily damaged
