Description

AGM baffle production facility

Technical Field

The invention relates to production equipment, in particular to AGM separator production equipment.

Background

The AGM separator, namely an ultra-fine glass wool separator, is generally a flaky flexible material with uniform texture, which is prepared from glass microfibers with the diameter of 0.5-3 mu m by a wet forming process similar to papermaking. The AGM separator is closely related to the valve-controlled sealed lead-acid storage battery, and the valve-controlled sealed lead-acid storage battery is called as a third pole, and mainly has the main functions of preventing short circuit between a positive plate and a negative plate in the battery, adsorbing electrolyte required by chemical reaction of the positive plate and the negative plate during charging and discharging of the battery, providing a channel through which oxygen generated during chemical reaction of the battery can permeate to the negative electrode, and enabling the oxygen to permeate the separator to be recombined into water on the negative electrode, so that maintenance-free or less maintenance is realized.

The AGM separator is made of microfibrous glass wool, so that it has both glass and fibrous characteristics, and is excellent in affinity with water, and excellent in resistance to acid corrosion, temperature, aging and oxidation. The AGM separator has large specific surface area, high porosity, high liquid absorption speed and good wettability, can absorb sufficient electrolyte solution, and has lower specific resistance. The AGM separator has good mechanical strength, excellent compression resistance and rebound resilience, can simultaneously meet the requirements of manual and mechanical pole plate coating, can enable the battery to be tightly assembled, reduces the battery volume, prevents the pole plate from mechanical deformation and the falling of active substances, and ensures the service life of the battery. The AGM separator has high chemical purity and low impurity content, and can ensure that the self-discharge rate of the battery is very low.

In general, the AGM separator follows the conventional inclined fourdrinier wet papermaking process, including a pulping section, a forming section, a drying and reeling section, a finished product post-processing and a packaging section. The production is continuous production with flow, and all the sections operate simultaneously. The key of the AGM separator forming technology is pulping, sizing, forming, drying and the like. In the process of forming the AGM separator, due to some human factors or external environmental factors, certain impurities, especially dark colored impurities, may be mixed, and the impurities are very obvious compared with the white AGM separator, and have a fatal influence on the quality of the AGM separator.

The uniformity of the AGM separator mainly refers to the uniformity of the thickness, so that the AGM separator is tightly attached to the polar plate, active substances are prevented from falling off, and meanwhile, the uniformity of electrolyte on the contact surface of the polar plate and the AGM separator is kept. When the AGM separator with good thickness uniformity is used for assembling the battery, the pressure on different parts of the AGM separator is more uniform, and the adsorbed electrolyte is also more uniform, so that the current distribution of the battery on each polar plate is more uniform during discharging; on the contrary, the AGM separator with poor uniformity has uneven pressure, large pressure at thick parts, less liquid absorption amount, small pressure at thin parts and large liquid absorption amount, so that the liquid absorption amounts at different parts of the AGM separator are different, and the current distribution on the battery plate is uneven.

In the prior art, the oven is generally subjected to forced hot air drying, the moisture content of each section of the process of the AGM clapboard oven is analyzed, and the moisture content of the clapboard before entering the oven is 66-72%. The moisture content of the AGM separator plate is 1-2% when the AGM separator plate reaches the middle part of the oven. Generally speaking, the total mass of the separator is 3kg when every 1kg of finished products enter the oven, wherein the water content is about 2kg, when the separator enters the middle part of the oven, only about 1kg of water and cotton are left, 2kg of water is volatilized, and 0.01-0.03 kg of water is also left. If the traditional design is unreasonable and the efficiency of the rear half is too low simply to remove 1% -2% of water, the data show that the thermal efficiency of the front half is higher and the energy consumption is lower, but the thermal efficiency of the rear half is too low, the energy consumption is too high and the cost is too high, and the energy is greatly wasted.

For example, Chinese patent publication numbers are: CN203269168, an AGM baffle winding mechanism who takes light to examine device that announces in 2013 at 11.6.2013, the on-line screen storage device comprises a base, be equipped with two carry over pinch rolls that arrange in proper order along AGM baffle direction of transfer on the base, be equipped with the light between two carry over pinch rolls and examine the device, the light examine the device including installing the box on the base, the box is located AGM baffle below, the box in be equipped with the light source that is used for examining the AGM baffle, the top of box is the light-emitting mouth. The mechanism can be used for detecting dark-colored impurities in the AGM separator, but fiber glass wool falling from the AGM separator is easily accumulated on the top of the box body of the mechanism, so that the optical detection effect is influenced. In addition, the AGM separator is rolled after being dried, and needs to be cooled before being rolled, and the currently common cooling method is to install a fan on a frame on one side of the AGM separator and blow fresh air for cooling. How to improve the cooling efficiency of the AGM separator during the optical inspection and reduce the influence of the fiber glass cotton on the optical inspection is an urgent problem to be solved.
