A curing system for polar plates

Abstract

The invention discloses a curing system for a polar plate, which comprises a curing chamber, a first fan and a regulating device. The regulating device is used for regulating the temperature and the humidity in the curing chamber; the curing chamber comprises a body, a curing chamber door and a separator; the front end of the body is provided with the curing chamber door and the rear end of the body is a closed end; the separator is arranged in the body from front to back and divides the body into a first chamber and a second chamber; a front turning air duct is formed between the curing chamber door and the front end of the separator; the first fan is provided with a cavity body; the cavity body is provided with an air outlet and an air suction port; one of the air outlet and the air suction port face towards the first chamber and the other one of the air outlet and the air suction port face towards the second chamber; a rear turning air duct is formed in the cavity body; and a ring-shaped air flow passage is formed among the first chamber, the rear turning air duct, the second chamber and the front turning air duct. According to the invention, an air flow circulation path is prolonged; low-resistance circulation of indoor air can be implemented without an external air duct; the air circulating resistance is low; the air distribution is uniform; no convection dead angle is generated; the polar plate is uniformly humidified and heated; and the effect of curing the polar plate is good.

Description

technical field [0001] The present application relates to the field of battery production, in particular to a curing system for polar plates. Background technique [0002] Plate curing refers to the completion of oxidation of free lead and lead on the surface of grid ribs and recrystallization of basic lead sulfate and hardening process. The quality of plate curing directly affects the performance of the battery, and the curing process is a key process in the battery production process. Curing chambers currently used in the industry such as figure 1 As shown, the effective volume of the curing room is about 4.4m*3.4m*2.8m. The working principle of this curing room is that the fan 4 provides the circulation of the internal air. When the humidity is lower than the set value, the water mist nozzle 2 Open, the water mist is accelerated by the fan 4, and then heated by the electric heating tube 5 to further atomize, and blown to the plate by the air duct, providing high-humidi...

AI Technical Summary

Problems solved by technology

Due to the large cross-section of the indoor air circulation direction in the existing curing room, the low wind speed and the small circulation distance, the humidification and heating of the plates are uneven, especially the curing effect of the upper and lower plates in the curing room is poor.
