Abstract

The utility model relates to an acid filter, belonging to an acid filtering and exhaust apparatus of lead-acid batteries, which comprises a faucet-style case, in which more than two acid filtering plates or acid filtering casings are separately arranged in laminated mode. Using the utility model on flooded lead-acid batteries, the acid fog in the storage batteries can be stopped from leaking out, thereby the acid pollution of the flooded lead-acid batteries to the environment can be eliminated.

Description

Acid filter

Technical field

The utility model relates to the sour exhaust apparatus of a kind of filter of lead acid accumulator.

Background technology

Hold the pond for pregnant solution type lead acid, escape contaminated environment and corrosion surrounding devices in order to prevent acid mist, generally all be provided with acid filter, but existing its filter acid film of acid filter or filter acid cover have only one, it is not good enough to filter sour effect.

Summary of the invention

The purpose of this utility model is can stop the efficient acid filter that acid mist is overflowed in the storage battery for pregnant solution type lead acid accumulator provides a kind of, thereby eliminates the acid pollution of pregnant solution type lead acid accumulator to environment.

The technical solution of the utility model is: undergo technological transformation on the basis of existing cock-type acid filter, i.e. the filter acid film or the filter acid of installing more than 2 in acid filter housing inner chamber spacer stack is covered.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model embodiment 1.

Accompanying drawing 2 is the structural representation of the utility model embodiment 2.

Embodiment

Embodiment 1, acid filter housing 4 adopts acidproof engineering plastics to make, its profile is gradin cock shape, downstairs level periphery is provided with the screw thread 6 that is connected and cooperates with Storage Battery Top Cover, the bottom surface offers some gas-liquid through holes 5, the gradin place is equipped with seal washer 7, housing 4 tops are provided with cover cap 2, offer transpiration hole 1 on the cover cap 2, at housing 4 inner chambers three filter acid films 3 are installed, they are lamination and the space certain distance, and filter acid film 3 adopts polytetrafluoroethylene or polyvinyl chloride, material such as corundum is also handled through special process and to be made, integral body has microcellular structure, can stop acid mist circulation but can allow hydrogen or oxygen gas pass through to overflow.

Embodiment 2, the structure of this acid filter, layout as housing 4, gas-liquid through hole 5, connecting thread 6, seal washer 7 is identical with embodiment 1 basically, the material of manufacturing (comprising filter acid film, cover) is also basic identical, what just install at housing 4 inner bottom parts is a filter acid film 3 (also can be filter acid cover), and two filter acid covers 8 have been installed on top, and uppermost filter acid cover 8 is gone back the cover cap of double as housing 4.Certainly, also can add a cover cap 2 again.

Test shows, after pregnant solution type lead acid accumulator uses the utility model, has stopped the effusion of the interior acid mist of storage battery basically, has protected the environment for use of pregnant solution type lead acid accumulator effectively.

Claims

1, a kind of acid filter comprises cock-type housing and filter acid film, it is characterized in that cock-type housing (4) inner chamber spacer stack is equipped with filter acid film (3) or the filter acid cover (8) more than two.
