Curing and drying control method for green plate curing and drying chamber

Abstract

The invention relates to the technical field of lead-acid storage battery green plate manufacturing. The invention discloses a curing and drying control method for a green plate curing and drying chamber. The method is realized on the basis of four groups of temperature and humidity sensors which are respectively positioned at four corners in the curing and drying chamber, and comprises a curing early-stage high-temperature moisturizing stage, a curing middle-stage medium-temperature dehumidifying stage, a curing later-stage high-temperature dehumidifying stage and a drying stage which are respectively controlled to be different in time proportion, so that corrosion of a green plate grid and oxidation of lead plaster free lead are facilitated; each start-stop time of each stage needs to beautomatically calculated and controlled by a PLC according to a positive deviation value of the temperature and the humidity in the last start-stop, so that the temperature and the humidity just reach a set value and the positive deviation value required by the process, and deviation value exceeding caused by rush height is reduced; the four groups of temperature and humidity sensors are adopted,the temperature and humidity detection is more accurate, the temperature and humidity control reference values in the four groups in each stage are different, physicochemical reaction in the green plate curing and drying process is facilitated, the energy loss is reduced, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of manufacturing lead-acid storage battery raw plates, in particular to a method for controlling curing and drying in a curing and drying room for raw plates. Background technique [0002] The manufacture of raw plates is particularly important in the manufacturing process of lead-acid batteries, and its quality directly affects the performance of the battery. The most important thing. The curing and drying process not only takes a long time and high temperature, but also plays a decisive role in the quality of the raw plate. It is a special process in the manufacturing process of the green plate, and its energy consumption accounts for 30% of the entire green plate manufacturing process. [0003] With the widespread use of lead-acid batteries in various fields such as electric power assist, car starting, electric tools, and backup power supplies, manufacturers have expanded their production capacity, and t...

Problems solved by technology

Although the current operation control program of the curing and drying room adopts PLC control, it only controls the operation of related components. How to reduce the consumption of compressed air, pure water, steam, etc. during the curing and drying process, and the control method for further energy-saving operation remains to be studied
