Air distribution screen suitably used for storage battery polar plate curing chamber

Abstract

The invention discloses an air distribution screen suitably used for a storage battery pole plate curving chamber. The air distribution screen comprises at least one air distribution unit, wherein the at least one air distribution unit is arranged at the side edge of the curing chamber, each air distribution unit internally comprises a ventilation cavity and an air supply cavity, the ventilation cavity is provided with a rectification segment and a pressurized segment along an air flow direction, the cross section of a cavity body of the rectification segment is gradually increased along an air direction, an air inlet is arranged at the top of the rectification segment, a diversion plate is arranged in the rectification segment, the bottom of the rectification segment is connected with the pressurized segment, pressurized plates with holes are arranged in the pressurized segment, the air supply cavity is communicated with the pressurized segment, and air outlets are arranged at parts, facing the side surface of the curing chamber, of the air supply cavity. The air distribution screen disclosed by the invention can have very high air supply uniformity for the curing chamber structures at arbitrary size and total air volume, the air speed difference among all air outlets is less than 10%, and the air distribution screen has relatively high universality.

Description

technical field [0001] The invention relates to the technical field of storage battery polar plate curing chambers, in particular to a wind distribution screen suitable for storage battery polar plate curing chambers. Background technique [0002] Lead-acid battery, also known as storage battery, was born in 1859. It is an electrochemical device that can realize the mutual conversion of chemical energy and electrical energy. Sulfuric acid solution), diaphragm and shell. The production process of lead-acid batteries involves nearly 20 processes such as powder making, plate casting, paste mixing, plate coating, plate repair, assembly, charging / battery formation, etc. Among them, the plate curing process is particularly important, and its quality is directly related to the quality of the battery. overall performance and lifespan. [0003] Plate curing is carried out in the curing room. The curing room uses fans, heating and humidification equipment to provide the required oxy...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to overcome the common problems of unreasonable dynamic and static pressure conversion, uneven air supply, low long-term reliability and poor universality of the wind screen in the curing room in the prior art. The adjustment of the pressure field is used as a means to provide an air distribution screen suitable for the battery plate curing room. The air distribution screen has a high uniformity of air supply, and the difference in wind speed of each air supply port is <10%, so as to maintain the air volume in the curing room, Uniform distribution of temperature and humidity, shorten the curing cycle, improve the quality and consistency of plate curing and lay the foundation
