Description

The filter acid mist acid receiver that is used for the 6-DGA-120 charge in batteries

One, technical field

The utility model relates to the charging servicing unit on a kind of 6-DGA-120 of being used for storage battery.

Two, background technology

The 6-DGA-120 charge in batteries is divided into two kinds, a kind ofly is that the pole plate assembling replenishes electricity, a kind ofly changes into for green plate assembled battery.No matter be that the pole plate assembling replenishes electricity or green plate assembled battery changes into, all be the electrolyte that battery is injected certain density and some, given charge technology feeds direct current after placing, and pole plate or green plate is handled, to reach the electric property of battery.

At present, the 6-DGA-120 battery capacity that my company's design is produced is big, and distance travelled is far longer than the automobile-used storage battery of market electric three-wheel, receives praises from customers.But because battery capacity is big, also can increase according to required sulfuric acid amount in the theoretical battery of electrochemical equivalent, with under the isometric(al), liquid level of electrolyte increases, if do not add any frock, in the battery charging process, because the charging reaction produces a large amount of gas, liquid level is risen, can cause that electrolyte overflows in the charging process, again because in the charging process, sulfuric acid overflows in pole plate or the green plate, in battery charging process, the volatile quantity of moisture is bigger, and density of electrolyte is increased simultaneously, charging finishes the single lattice density of electrolyte in back and need adjust, because each single lattice acid amount loss differs greatly, the density of electrolyte deviation is big, and the workload of adjusting density of electrolyte is relatively large.If it is unrealistic that each single lattice of every battery all are adjusted to the scope that density of electrolyte meets specification requirement.The inconsistent of density of electrolyte will directly influence battery performance.Because gas is taken acid solution out of when separating out, be dispersed in and form acid mist in the air in the charging process, be corrosive, also can cause environment to have a strong impact on.

Three, summary of the invention

The utility model is exactly to overcome the above-mentioned shortcoming that exists in the prior art, and the electrolyte that can will overflow when a kind of the charging is provided stores, and can be back to the filter acid mist acid receiver that is used for the 6-DGA-120 charge in batteries of discharge list lattice after charging is finished again.

For finishing above-mentioned purpose, technical solution of the present utility model is: a kind of filter acid mist acid receiver of the 6-DGA-120 of being used for charge in batteries is characterized in that: it comprises storage sour body, sealing bolt and sealing ring; Store up sour body upper port jam-pack sealing bolt, its end opening has the external screw thread with 6-DGA-120 storage battery integral cap key screw-internal thread fit, and sealing ring is set on end opening.

The above-mentioned described sealing bolt of the utility model comprises key, sealing cap, air flue, polypropylene air filter piece, gentle lid of stopper; Air flue is set in the middle of the key, there is sealing cap the lower end of air flue, and sealing cap is the retaining acid structure that has gas passage, and there is the polypropylene air filter piece upper end of air flue, sealing bolt internal fixation in the upper end of polypropylene air filter piece has gas sheet lid, is connected with stopper in the key of the outer upper end of gas sheet lid.

The sealing cap of the sour structure of the above-mentioned described retaining of the utility model has inside and outside wall, and respectively there is an acid-blocking piece lower end of inside and outside wall, and acid-blocking piece one side of outer wall lower end can be opened, and the opposing acid inlet in position is respectively arranged on the inside and outside wall, and its upper end is fixed on the key.Like this, acid solution is no longer taken out of with the discharge of electric power storage pool gas under the effect of acid-blocking piece and the acid inlet of separating.

The above-mentioned described stopper of the utility model is crimped on the upper end of sealing bolt key, and the gas sheet lid in it is welded on the sealing bolt key inwall in the ultrasonic wave mode.

Because the utility model adopted such scheme, be installed in before the battery charge on each liquid injection hole of 6-DGA-120 storage battery and screw.When charge in batteries, its inner vigorous reaction, acid solution overflow, the acid solution of overflowing are stored in the filter acid mist acid receiver, make acid no longer excessive, the damage surrounding environment.After charging was finished, electrolyte was steady, and it is back to again in the discharge list lattice, and the acid amount loss in single lattice is significantly reduced, and the density of electrolyte in each single lattice is in a basic balance, not be used in very short time to adjust, and has reduced the use operating procedure, uses simple.Especially sour structure of band retaining and polypropylene air filter piece on sealing bolt keep off sour structure and can effectively stop storage battery when charging, and the generation of the situation that the acid solution overflow is spattered outward makes acid solution be back to the sour body of storage by force; The polypropylene air filter piece has then filtered out the acid solution of being taken out of when the electric power storage pool gas is discharged, and makes acid solution no longer be taken outside the battery out of contaminated environment.In a word, during charging, 6-DGA-120 storage battery of the present utility model is installed, can be prevented effectively that battery electrolyte from overflowing, guarantee the consistency of cell negative terminal liquid measure and density; Battery charge does not need that environment is had special requirement; Can adjust density of electrolyte by task equipment, reduce the difficulty of adjusting density of electrolyte, realize adjusting the mechanization of density of electrolyte, improve production capacity, reduce cost.And the minimizing acid mist is to the influence of environment.Guaranteed battery performance.
