Technical Field

The utility model relates to a battery field, concretely relates to non-maintaining accumulator cover's acid returning structure.

Background

When the lead-acid storage battery works, water vapor and certain temperature can be generated, the generated water vapor is emitted to the atmosphere through the exhaust pipe, meanwhile, the water vapor can be discharged with acid liquor, the performance of the battery can be deteriorated after a long time, the requirement cannot be met, and the battery shell, the using equipment and the like can be corroded. Due to the direct contact of acid, if the maintenance is poor, the exhaust pipe can be blocked, so that the deformation of the shell of the storage battery caused by overlarge air pressure in the storage battery is caused, and potential safety hazards are caused.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: aiming at various defects and shortcomings of the prior art, the acid recovery structure of the maintenance-free storage battery cover is provided.

The utility model discloses a concrete technical scheme is: the utility model provides a return acid structure of non-maintaining battery cover, including upper cover and lower cover, the lower cover is equipped with the return surface, return surface a week is equipped with outer gusset and encloses, return surface one side is equipped with the blast pipe of the same horizontal axis of a plurality of, separate by interior gusset between the blast pipe, be equipped with the sour strip of keeping off towards the blast pipe relatively on outer gusset and the interior gusset, the blast pipe is equipped with out the acid mouth for the back of keeping off the acid strip, interior gusset and fender acid strip separate the return surface into acid groove and acid storage tank, the return surface is located the acid mouth and is the minimum, it is the peak to be located acid storage tank, be equipped with the inclination according to the route.

Furthermore, the upper cover is provided with an outer rib plate, an inner rib plate and an acid blocking strip which are matched and attached with the lower cover, so that the upper cover forms an acid return groove and an acid storage groove which are integrated with the lower cover, the upper cover is provided with an exhaust pipe cover corresponding to the exhaust pipe, the inner rib plate between the exhaust pipe covers is arranged on one side of the acid storage groove and is provided with an internal exhaust port, and the upper cover is arranged on the acid storage groove and is provided with an exhaust hole.

During the use, vapour in the battery can take acidizing fluid together to discharge to the acid outlet from the blast pipe, the blast pipe discharge capacity placed in the middle is the biggest, its corresponding sour route of returning is also longer, still be equipped with and store up the acid groove, vapour gets into along returning the acid groove and stores up the back, discharge from the venthole, the acidizing fluid just slowly piles up at the acid outlet, after waiting to measure the back to return to the acid groove and go, it controls sour liquid flow and velocity to keep off the acid strip, can make its fall-back speed accelerate again, flow back to the battery, even discharge acid for a long time, also there is the buffering of acid groove, guarantee that the battery works for a long time and do not leak acid, wait to stop using the back, the acidizing fluid flows back to the.

The acid discharge amount of the exhaust pipes on the two sides is reduced in sequence, and the requirements can be met only by arranging the acid return grooves with acid blocking strips or directly returning acid through the return surface.

The utility model discloses owing to adopted above technical scheme, had following advantage: 1. the problem of acid leakage of the storage battery is solved, the service life of the storage battery is prolonged, and the working performance is more stable. 2. The harm to personnel or equipment caused by acid leakage of the storage battery is avoided.

Detailed Description

Embodiments of the present invention will be described with reference to the accompanying drawings.

The acid return structure of the maintenance-free storage battery cover comprises an upper cover 1 and a lower cover 2, wherein the lower cover 2 is provided with a return surface 21, an outer rib plate 22 is arranged around the return surface 21, a plurality of exhaust pipes 31 with the same horizontal axis are arranged on one side of the return surface 21, the exhaust pipes 31 are separated by an inner rib plate 23, acid blocking strips 24 facing the exhaust pipes 31 are oppositely arranged on the outer rib plate 22 and the inner rib plate 23, an acid outlet 25 is arranged on the back of the exhaust pipes 31 opposite to the acid blocking strips 24, the return surface 21 is separated into an acid return groove 26 and an acid storage groove 27 by the inner rib plate 23 and the acid blocking strips 24, the acid outlet 25 is the lowest point of the return surface 21, the acid storage groove 27 is the highest point, and an inclination is arranged according to a path.

Furthermore, the upper cover 1 is provided with an outer rib plate 22, an inner rib plate 23 and an acid blocking strip 24 which are matched and attached with the lower cover 2, so that an acid return groove 26 and an acid storage groove 27 which are integrated with the lower cover 2 are formed, the upper cover 1 is provided with an exhaust pipe cover 28 corresponding to an exhaust pipe 31, an inner exhaust port 29 is arranged on one side, located on the acid storage groove 27, of the inner rib plate 23 between the exhaust pipe covers 28, and the upper cover 1 is provided with an air outlet 30 located on the acid storage groove 27.

When the acid storage battery is used, steam in the storage battery can carry acid liquor to be discharged to the acid outlet 25 from the exhaust pipe 31 together, the exhaust pipe 31 in the middle is largest in discharge capacity, the corresponding acid return path is also longer, the acid storage tank 27 is further arranged, steam enters the acid storage tank 27 along the acid return tank 26 and then is discharged from the air outlet 30, the acid liquor is slowly accumulated at the acid outlet 25 and flows to the acid return tank 26 after the acid liquor comes up, the acid baffle strip 24 controls the flow rate and the flow speed of the acid liquor and can accelerate the falling speed of the acid liquor and flow back to the storage battery, the acid storage tank 27 buffers the acid liquor even if the acid is discharged for a long time, the storage battery is ensured not to leak acid after the storage battery works for a long time, and the acid liquor flows back to.

The acid discharge amount of the exhaust pipes 31 at the two sides is reduced in sequence, and the requirement can be met only by arranging the acid returning grooves 26 by using the acid blocking strips 24 or directly returning acid through the return surface 21.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
