Description

A kind of injection device of colloidal electrolyte of lead acid batteries
Technical field
The utility model relates to a kind of injection device of electrolyte, relates in particular to a kind of injection device of lead-acid electrolyte for accumulator, more specifically relates to a kind of negative pressure of utilizing and makes colloidal electrolyte be injected into injection device in the high-capacity lead-acid storage battery fast.
Background technology
In the production process of high capacity cell, electrolytical injection has two kinds of methods usually, and a kind of is promptly to begin to inject electrolyte after pole plate, dividing plate at battery installs, and seals then; Another kind method is just to seal after pole plate, the dividing plate at battery installs, and adopts equal-pressure method that electrolyte is filled in the battery.The shortcoming of first kind of method for implanting is that in the process of sealing, electrolyte was very easily excessive, not only easily operational environment is polluted, and workers'health is also had infringement, thereby this method is eliminated gradually after electrolyte was filled it up with; Though second kind of method for implanting can solve the excessive problem of electrolyte, but because electrolyte is to inject inside battery from battery battery core top, air in the battery is difficult to discharge, so just cause battery that the speed of electrolyte absorption is become slow, need to divide filling several times, have a strong impact on production efficiency, and sometimes because can't the draining of air, and electrolyte can't be filled.Because the viscosity of colloidal electrolyte ratio of viscosities liquid electrolyte is big, more increased the difficulty of perfusion, so people have proposed a kind of vacuum injection process, this method is to adopt the container of a funnel type, make the electrolyte injection opening of the discharging opening aligning storage battery of container, quantitative electrolyte is put in the container, allow electrolyte under the effect of own wt, flow in the battery automatically, the speed that flows into when electrolyte is slack-off even when stopping, battery and container be put in the vacuum machine together vacuumize, after residual air was discharged, the electrolyte in the container entered in the battery fast, finishes whole filling process.Adopt the vacuum injection process can accelerate the speed that electrolyte injects greatly, add very suitable, but inapplicable for the electrolytical notes of small battery for jumbo battery, reason is, high capacity cell self is very heavy, adds electrolyte, moves quite difficulty, and general vacuum machine, also enough not big molten amassing can be held jumbo battery, in addition, and in the process that vacuumizes, the loam cake of battery is vulnerable to pollute very much, climbs the alkali phenomenon thereby cause battery to be prone in storage process.
Summary of the invention
For overcoming the problem of above existence, the purpose of this utility model provides a kind of injection device of colloidal electrolyte of lead acid batteries, and this injection device can be injected into colloidal electrolyte in the high-capacity lead-acid storage battery under free of contamination situation fast.
For realizing above purpose, colloidal electrolyte of lead acid batteries injection device of the present utility model comprises a container, it is characterized in that: described container bottom is provided with discharging opening, discharging opening be connected with one " " the type three-way pipe; the upper end of three-way pipe vertical section is connected with container, the lower end is used for is connected with the electrolytical inlet of battery colloidal; the end of three-way pipe traversing section is connected with vacuum pump, and the vertical section that is positioned on three-way pipe traversing section and the vertical section interface is provided with dispensing valve.
In order to make colloidal electrolyte can inject battery more fast, also for container bottom is difficult for accumulating colloidal electrolyte, the bottom of said vesse is funnel type, and the neck of funnel is connected with the upper end of above-mentioned three-way pipe vertical section.
In order to monitor the vacuum degree of inside battery at any time, the traversing section of above-mentioned three-way pipe is connected with the vacuum measurement table.
In order to make the colloidal electrolyte injection device can finely be positioned on the colloidal electrolyte inlet of cell cover when the liquid feeding, the bottom of above-mentioned three-way pipe vertical section is stepped, the three-way pipe discharging opening end that is connected with cell cover, its caliber is littler than the caliber of three-way pipe vertical section, and the internal diameter of the external diameter of three-way pipe discharging opening end and cell cover colloidal electrolyte inlet is suitable.
Tightr for the colloidal electrolyte injection device can be cooperated with battery cover when the liquid feeding, the terminal lateral wall of above-mentioned three-way pipe discharging opening is provided with the fixture block that can form interface arrangment with cell cover colloidal electrolyte inlet.
The lateral wall of above-mentioned three-way pipe discharging opening end also can be provided with the external screw thread that forms the structure that spins with cell cover colloidal electrolyte inlet.
Colloidal electrolyte of lead acid batteries injection device of the present utility model, owing to be connected with three-way pipe at the container discharging opening that holds colloidal electrolyte, one end of three-way pipe is connected with vacuum pump, when colloidal electrolyte does not inject, can earlier the air of inside battery be taken away, make inside battery form negative pressure, colloidal electrolyte just can inject battery fast like this, and after colloidal electrolyte fills with, need not carry out follow-up operation, can avoid the excessive of colloidal electrolyte, thereby reduce to the pollution of operational environment with to operator's injury.
