Description
Affiliated technical field
The utility model relates to a kind of aluminum hull dry cell.
Background technology
At present, dry cell is by guiding subassembly, black box, positive pole, barrier film and negative pole composition, and its shell is zinc cylinder.The zinc cylinder of this dry cell is along with the carrying out of dry cell electric discharge, and zinc cylinder, because participating in constantly attenuation of chemical reaction, because dry cell internal-response is inhomogeneous, causes the some places of zinc cylinder to be dissolved completely and causes leakage, causes dry cell to be scrapped.Meanwhile, this dry cell of making shell with zinc cylinder, the major part of its zinc, just as metallic conductor and container, causes most of zinc waste.
Summary of the invention
In order to overcome existing dry cell because using zinc cylinder to make shell, and the deficiency that causes dry cell leakage and zinc to be wasted, the utility model provides a kind of aluminum hull dry cell, and this aluminum hull dry cell can effectively prevent the generation of dry cell leakage, and can save part metals zinc.
In order to achieve the above object, to solve the technical scheme that its technical problem adopts be following design to the utility model:
The shell of battery is aluminum barrel, paper tinsel shape zinc is attached on the inner cylinder face of aluminum barrel, pulp layered paper is attached on the inner cylinder face of paper tinsel shape zinc, bottom insulation paper is positioned at the lower end of pulp layered paper, and be close to the bottom of aluminum barrel, top insulating paper is positioned at the upper end of pulp layered paper, and positive mix is wrapped up in by pulp layered paper, top insulating paper, bottom insulation paper bag.Insert in positive mix through the central circular hole on the insulating paper of top the bottom of carbon-point, the circle hole sleeve of lower barrier paper, upper barrier paper is on carbon-point, simultaneously, lower barrier paper covers on the insulating paper of top, and surround air chamber with top insulating paper, sealing compound is by the top seal of lower barrier paper, and the top of sealing compound is covered by upper barrier paper.Copper cap is held in the top of carbon-point, and central round-meshed Jiao Gai is enclosed within on copper cap and pushes down barrier paper and the shade of copper cap, upper the pushing down along crimping of glue cover aluminum barrel.
The height of the aspect ratio positive mix of paper tinsel shape zinc is slightly higher, the diameter of top insulating paper, bottom insulation paper is consistent with the interior circular diameter of pulp layered paper, there is the circular hole matching with carbon-point in the central authorities of top insulating paper, the diameter of lower barrier paper, the diameter of upper barrier paper and the inner cylinder face of aluminum barrel is consistent, and there is the circular hole matching with carbon-point in central authorities.
When work, positive mix and paper tinsel shape zinc carry out chemical reaction and discharge, and the electronics discharging is got back in positive mix through aluminum barrel, outside electrical appliance, copper cap, carbon-point.Meanwhile, the chemical reaction that positive mix and paper tinsel shape zinc carry out and the liquid that forms are subject to the prevention of aluminum barrel and can not overflow.
The beneficial effects of the utility model are: can effectively prevent the generation of dry cell leakage, meanwhile, reduce the use amount of the metallic zinc that price is high, and production cost is reduced.
