Embodiment Construction

[0023] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them.

[0024] Step 1: Adjust the size of the air outlet (the gap between each air screen) of the air screen 2 in the curing room to ensure that the maximum wind speed difference at each position does not exceed 0.5m / S. The detailed data is shown in Table 1:

[0025] Table 1

[0026]

[0027] Step 2) Place the 100,000 pieces of wet plates 1 coated with lead paste in the curing room adjusted in step 1) for curing. After the wet raw plates 1 are cured, the moisture content of the wet plates 1 is 4.5%, and enter the drying stage .

[0028] Step 3) In the drying stage, adjust the curing indoor environment to a temperature of 85°C. At this time, close the air inlet door 3 and the air outlet door 4, and rely on the evaporation of ...

Abstract

The invention discloses a storage battery pole plate and a drying process and device thereof. The drying process comprises the following steps of curing a green pole plate coated with a lead plaster and then entering a drying stage; adopting intermittent dehumidification at the drying stage, and setting the humidity control upper limit during dehumidification. By means of the moisture evaporationof the polar plate, the wet air is exhausted when the humidity reaches the upper limit, the dry air is absorbed at the same time, then the dehumidification and air inlet functions are closed for indoor air circulation to realize the internal air flowing, so that the temperature and humidity of the internal air are consistent; after the moisture in the lead plaster diffuses into the circulating air, and when the humidity reaches the humidity upper limit again, the dehumidification and air inlet operations are carried out. Along with the gradual drying of the polar plate, the circulating air exhaust is reduced gradually in stages to control the humidity upper limit, so that the polar plate is dried. Compared with the prior art of carrying out the dehumidification and air inlet operations allthe time, the energy is saved, the consumption is reduced, and the surface of the pole plate can be prevented from cracking due to too fast drying. Through the circulation operation, the purpose of drying the polar plate is finally achieved, and the energy consumption can be saved by 10-25% of the energy consumption of a total curing cycle.

Description

technical field [0001] The invention belongs to the field of lead-acid storage batteries, and in particular relates to a drying process for producing lead-acid storage battery pole plates. Background technique [0002] At present, many battery factories use the stacking method to cure the extended plates. This method can make full use of the resources of the curing room, but the curing time is long and the energy consumption is high. Analysis of green board curing energy consumption from the total curing cycle (curing stage and drying stage): In the process of green board curing and drying, the energy consumption in the drying stage is much higher than that in the curing stage, because the temperature of the green plate is high in the drying stage and the equipment discharge The humid fan runs all the time and takes away a lot of heat energy. Contents of the invention [0003] The purpose of the present invention is to provide a storage battery pole plate drying process t...
