Pressure container curing chamber and curing method thereof

Abstract

The invention relates to the technical field of pressure container curing chambers of lead-acid storage battery production equipment, in particular to a pressure container curing chamber and a curing method thereof. The pressure container curing chamber comprises a curing chamber body, a circulating fan and a pressure container chamber are respectively arranged inside the curing chamber body, a vapor generator and an atomizer are arranged in the pressure container chamber, and a PLC (programmable logic controller) control device is arranged outside the curing chamber body. The pressure container curing chamber is characterized in that a compressed air or compressed oxygen inlet and a vacuum compressor connector are arranged on the side walls of the curing chamber body respectively, and a compressed air heater is arranged between the pressure container chamber and the curing chamber body. The pressure container curing chamber is simple in structure, short in curing time, higher in drying efficiency, more thorough in drying and shorter in working procedure time.

Description

[0001] technical field [0002] The invention relates to the technical field of a pressure vessel curing chamber of a lead-acid storage battery production equipment. [0003] Background technique [0004] Lead-acid batteries are the most widely used secondary batteries at present. The manufacturing process is mature, but the cycle is long and the energy consumption is large, especially in the curing and drying of the plates. [0005] The so-called curing means that after the active material is coated on the grid to make a wet plate, the plate is placed in a closed space and hardened and dehydrated under the specified temperature and humidity conditions. During this process, the remaining free particles in the plate Lead is converted into lead oxide, lead paste is combined with grid corrosion, and active material recrystallizes to form a special crystal structure and porous structure. After this process is completed, the free lead content in the plate is less than 3%, and th...

AI Technical Summary

Problems solved by technology

At present, the more advanced curing room, the inner surface is made of stainless steel, the outer surface is made of color steel, and the interlayer is a polyurethane curing room. The curing room is equipped with circulating fans, heaters, steam generators, atomizers, etc., and is controlled by PLC and touch screen. Monitoring and intelligent instruments control temperature and humidity, and the entire curing and drying process is automated, but the process time cannot be shortened. Generally, curing takes 48 hours and drying takes 24 hours, totaling about 72 hours
