Abstract
The utility model relates to a leakless and maintenance-free lead-acid accumulator, which is composed of a polar plate sealed in an accumulator casing, the electrolyte and electrodes connected with the polar plate. The top cover of the casing is provided with a ventilation catalyst chamber storing the catalyst formed by the mixing and drying of silicon oxide, platinum metal and water repellent. The catalyst chamber is provided with a safety valve, and because the water vapor can enter the catalyst chamber and circulate passing the action of the catalyst without overflowing and loss, the utility model can not pollute the environment but can reduce the use cost.
Description
The utility model relates to a kind of lead acid accumulator.
Existing lead acid accumulator is made up of the electrode that is connected with pole plate on electrolyte between the pole plate in housing, the housing and pole plate and the housing, can store and supply electric energy effectively.But in use, electrolyte and pole plate generation chemical reaction, produce acid steam and need discharge storage battery, storage battery just can not tightly seal like this, otherwise vapour pressure is the rising accumulator housing that can rise brokenly constantly, and because the moisture content in the electrolyte constantly discharges, also needs regularly to replenish distilled water or change electrolyte to battery, so not only bothered but also increased the use cost of storage battery, the sour gas of discharging and the electrolyte that overflows are also very serious to the pollution of environment.
The purpose of this utility model provides and a kind ofly can tightly seal, the lead acid accumulator of non-maintaining, long service life.
Task of the present utility model is finished with following scheme: having designed has pole plate and electrolyte in a kind of housing, the lead acid accumulator that has electrode to be connected on the housing with pole plate, the housing of storage battery is tightly sealing after installing pole plate, electrolyte, and a ventilative catalyst case is arranged in the end face of accumulator housing internal polar plate top.Ventilative catalyst case is fired with silicate material mixing diamond dust and is formed.The top is provided with safety valve on catalyst case and the storage battery, to guarantee safety, prevents superpressure in the housing and explosion.Catalyst in the catalyst case can be formed as platinum, rhodium, palladium etc. and water-repellent agent mixing oven dry by silicon oxide particle and platinum group noble metal.Because the gas that electrolyte and pole plate course of reaction produce in the accumulator housing can penetrate catalyst case, behind catalyst action, the water of aggegation penetrates catalyst case again and bleeds back in the electrolyte, so circulates and the accumulator housing of not overflowing.Therefore, the utility model lead acid accumulator did not in use both pollute the environment, can be in order to avoid safeguard that obviously prolong useful life yet.
Embodiment describes the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model lead acid accumulator schematic diagram.
As shown in Figure 1, in the housing 1 of the utility model lead acid accumulator pole plate 2 is arranged, filling electrolyte 3 between the pole plate 2, pole plate 2 links to each other with electrode 8, the top cover of housing 1 has ventilative catalyst case 5 for 7 times, on ventilative catalyst case 5 and the top cover 7 pressure relief safety valve 9 is arranged, and catalyst 6 is arranged in the catalyst case 5, after charging electrolyte 3, sealing between housing 1 and the top cover 7.
Claims (1)
- Pole plate and electrolyte are arranged in a kind of housing, and the lead acid accumulator that has electrode to be connected with pole plate on the housing is characterized in that the housing of said storage battery tightly seals, and a ventilative catalyst case is arranged in the end face of housing internal polar plate top, and catalyst case is provided with safety valve.
