Abstract
The utility model relates to a sealed lead-acid storage battery which comprises a casing, a casing cover and a battery jar. The casing comprises a hollow cavity, the casing cover is arranged on the casing, the battery jar is divided by a partition plate, an electrode plate is positioned in the battery jar, an air outlet is formed in the battery jar, an alkaline sucking cotton layer is arranged in the hollow cavity of the casing close to the periphery of the inner wall, the alkaline sucking cotton layer is in a compact grid shape, the alkaline sucking cotton layer can neutralize acid liquid in gas, a protection film layer is arranged in the casing, and a pressure adjusting device is arranged on the lateral side of the casing cover. The acid liquid in the gas can chemically react with the alkaline sucking cotton to be converted into non-poisonous and harmless substances to be left in the casing. Thus, the gas is prevented from volatilizing, and the environment is prevented from being polluted. When certain pressure achieves, the pressure adjusting device can automatically balance internal pressure and external pressure to avoid danger.
Description
Technical field
The utility model relates to the storage battery field, relates in particular to a kind of sealed type lead acid battery.
Background technology
Conventional accumulators is called again lead acid accumulator, its electrode is to consist of plumbous and plumbous oxide, electrolyte is the aqueous solution of sulfuric acid, lead acid accumulator is because it is cheap, raw material are easy to obtain, sufficient reliability is arranged in use, be applicable to heavy-current discharge and the advantage such as ambient temperature range widely, be widely used in chemical power source.
Existing lead acid accumulator comprises housing, be located at cap on housing, be located at electrolyte in housing and pole plate group etc., because the acid aqueous vapor that electrolyte in use procedure and positive and negative pole plate generation chemical reaction produce need be discharged storage battery, so just make storage battery tightly not seal, storage battery is not airtight easily causes the electrolyte leakage in storage battery excessive, the acid aqueous vapor of discharging and the electrolyte that overflows not only can be to environments, the equipment around also can corroding.In addition, because water in housing can be decomposed into hydrogen, carrier of oxygen is separated out, so need the use cost that frequent accumulators acid adding, Jia Shui, maintenance work are heavy, increased storage battery.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and the sealed type lead acid battery of a kind of simple and reasonable, environmental protection and long service life is provided.
The utility model is to be achieved through the following technical solutions:
A kind of sealed type lead acid battery; comprise housing with hollow reservoir, be located at cap and battery case on housing; described battery case is separated it by dividing plate; be provided with pole plate in battery case, be provided with venthole on battery case, the hollow reservoir of described housing is provided with alkaline suction layer near the surrounding of inwall; described alkaline suction layer is the dense mess trellis; alkalescence suction layer, with the neutralization of the acid solution in gas, is provided with the layer protecting film layer in described housing, the side of described cap is provided with pressure-regulating device.
Further, described protective film is alkaline-resisting acid resisting material layer.
Further, the thickness of described protective film is 2-4mm.
Further, described housing and cap are that cassette is tightly connected.
Compared with prior art, the beneficial effects of the utility model are: the acid solution in the utility model gas directly with alkaline suction layer generation chemical reaction, convert thereof into nontoxic material and be retained in housing, prevent that its volatilization from going out, contaminated environment; When pressure reaches one regularly, the pressure that the pressure-regulating device autobalance is inside and outside, prevent danger.
