Description

Technical Field

Background Art

[0002] The main process of the active material in the plate during the curing process: 1. Oxidation of metal lead in the active material; 2: Corrosion oxidation and gelation of the interface (the contact surface between the grid and the active material); 3. After the curing is completed, the plate is dried. The above three processes have different requirements for the moisture content of the plate and the temperature and humidity inside the curing chamber. The process conditions need to be adjusted as soon as possible during the process conversion stage. The top of the current curing chamber is equipped with a circulating fan, a heating pipe, a circulating wind baffle and an exhaust pipe extending to the outside. The inner wall of the curing chamber is equipped with an atomized water nozzle, and the top surface of the curing chamber is equipped with a curing chamber air inlet. The curing chamber adjusts the temperature by heating the heating pipe, and diffuses the heat to the entire curing chamber through the circulating fan. The supplementary oxygen relies on the natural diffusion of the inlet and outlet dampers, the humidity is increased by atomized water humidification, and the dehumidification is reduced by natural dehumidification through the inlet and outlet dampers or dehumidification by the dehumidification fan.

[0003] The disadvantages of adjusting the indoor temperature and humidity in the existing plate curing room are: 1. The natural convection of the inlet and outlet air doors replenishes oxygen slowly, and the metal lead oxidizes slowly, resulting in a longer curing time; 2. Natural dehumidification takes a long time, and the slow stage conversion leads to reduced production efficiency and increased curing energy consumption; 3. High-temperature drying consumes a lot of energy. Summary of the invention
