Abstract
The utility model belongs to battery electrolyzer covers the improvement of field, concretely relates to electrolyzer cover overflow cistern. The utility model aims to provide an unhurried current type battery electrolyzer lid can slow down the acidizing fluid in the mobile speed of discharge inslot, makes more acidizing fluids in the battery is flow back into in the discharge hole, including the discharge groove, the discharge inslot is equipped with the discharge hole, separate through the partition wall between the adjacent discharge hole, each partition wall top all is equipped with the breach that can supply the acidizing fluid to flow through. Separate through the partition wall between the adjacent discharge hole, the acid mist is followed the discharge hole and is appeared the liquefaction back, and the partition wall plays the effect that hinders the interception acidizing fluid, and messenger's acidizing fluid has abundant buffer time backward flow, each partition wall top all is equipped with the breach that can supply the acidizing fluid to flow past, and when the acidizing fluid was too much, the breach can release away the acidizing fluid, prevents that discharge seal lock stopper from leading to the fact the acid mist normally to appear to it is too big to avoid battery internal pressure.
Description
Technical field
The utility model belongs to storage battery groove lid field, is specifically related to the improvement that electric groove covers polyrrhea groove.
Background technology
Current storage battery mainly refers to lead acid accumulator, and plumbic acid needs battery all can produce acid mist in production and use procedure.The formation mechenism of acid mist mainly contains two kinds: one is acid solution surface evaporation, and sulfuric acid molecule enters air, and the moisture in air is combined and forms sulfuric acid droplet; Another kind is chemical reaction in sulfuric acid solution, and explosion after formation bubble floating to liquid level, takes out of droplet.In prior art, the measure reducing acid mist precipitation mainly contains: 1) suppress charging process terminal voltage, make it the voltage being no more than water decomposition; 2) battery polarization electromotive force is reduced, as improved active material real table area, reducing electrode thickness etc.; 3) oxygen evolution electromotive force is improved; 4) in lead plaster, grid and electrolyte, the precipitation that various additive (alloy) reduces gas is added; 5) utilize negative pole overflow method, positive electrode active material utilization is improved, reduce gassing rate.Facts have proved, the most effective purification method is mechanical filter method, and acid mist, through stopping and absorption layer by layer, is trapped on filter course, and gets back in solution because of Action of Gravity Field.
Utility model content
The purpose of this utility model is to provide a kind of storage battery groove lid, can slow down the flowing velocity of acid solution in polyrrhea groove, and more acid solution is refluxed in battery through liquid overflow hole.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of unhurried current type storage battery groove lid, comprises polyrrhea groove, be provided with liquid overflow hole in described polyrrhea groove, separated by partition wall between described adjacent liquid overflow hole, each partition wall top is equipped with the breach that can flow through for acid solution.
Preferably, described breach is the right-angle notch being arranged on described partition wall side, and the breach direction between adjacent two partition walls is contrary.
Preferably, stretch out described electric groove lid outside described polyrrhea groove one end, be provided with steam vent in described overhanging end, in described steam vent, be provided with air filter piece.
Preferably, described steam vent is up big and down small shoulder hole, and described air filter piece is filled in the macropore of described shoulder hole.
The utility model has following beneficial effect: separated by partition wall between described adjacent liquid overflow hole, acid mist separates out post liquefaction from liquid overflow hole, and partition wall plays the effect hindering interception acid solution, makes acid solution have sufficient buffer time to reflux; Each partition wall top is equipped with the breach that can flow through for acid solution, and when acid solution is too much, acid solution can discharge by breach, prevents liquid overflow hole from blocking and causes acid mist normally not separate out, thus avoid internal storage battery pressure excessive.In prior art, between adjacent liquid overflow hole, there is no partition wall, after acid mist liquefaction forms acid solution, position flowing that can be minimum in polyrrhea groove, is then deposited on lowest part, makes acid solution can not reflux in storage battery, finally cause concentration of electrolyte constantly to decline, accumulator property declines and even lost efficacy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of unhurried current type storage battery groove lid, comprises polyrrhea groove, is provided with liquid overflow hole 1 in described polyrrhea groove, and the acid mist produced in storage battery is separated out by liquid overflow hole 1, to reduce internal storage battery pressure; Separated by partition wall 2 between described adjacent liquid overflow hole 1, acid mist separates out post liquefaction from liquid overflow hole 1, partition wall 2 plays the effect hindering interception acid solution, acid solution is made to have sufficient buffer time to reflux, each partition wall 2 top is equipped with the breach 3 that can flow through for acid solution, and when acid solution is too much, acid solution can discharge by breach 3, preventing liquid overflow hole 1 from blocking causes acid mist normally not separate out, thus avoids internal storage battery pressure excessive.Described breach 3 is for being arranged on the right-angle notch of described partition wall 2 side, acid solution flows toward the direction of breach 3 all the time, breach 3 direction between adjacent two partition walls 2 is contrary, the flow trace of acid solution will be made to form broken line, play the effect slowing down acid solution flowing velocity further.Stretch out described electric groove lid outside described polyrrhea groove one end, be provided with steam vent 4 in described overhanging end, be provided with air filter piece in described steam vent 4, do not have the acid mist liquefied can discharge from steam vent 4, air filter piece can filter acid mist, reduces the pollution to environment.Described steam vent 4 is up big and down small shoulder hole, and described air filter piece is filled in the macropore of described shoulder hole, and of the prior art is straight hole, and air filter piece filter area is less, and compared with prior art shoulder hole is conducive to increasing air filter piece, improves filter effect.
