Lead acid accumulator is annotated sour funnel
The utility model relates to lead acid accumulator and produces appurtenance, and particularly a kind of lead acid accumulator is annotated sour funnel.
It is that battery is annotated frock commonly used in the sour process that lead acid accumulator is annotated sour funnel.Annotate sour funnel and generally adopt pvc pipe to make, its effect injects the electrolyte into inside battery, plays storage, guide functions.Present lead acid accumulator industry, small-capacity cells generally adopt vacuum impregnating acid, and solving electrolyte influences the problem that electrolyte gets into inside battery because of vapour lock; High capacity cell is because battery is heavier, and volume is bigger, and it is bigger to carry out vacuum impregnating acid operation inconvenience and equipment investment, generally adopts the normal pressure formula that pours into to annotate acid.
The sour funnel of common notes is generally cylindrical, and annotating bayonet socket place, sour funnel bottom has rubber ring, and the funnel bayonet socket cooperates with the interior bayonet socket of battery valve port during upper hopper, and rotation is tightened, and rubber ring seals.This common notes acid funnel when the normal pressure formula that pours into is annotated acid, is easy to generate vapour lock, influence electrolyte and get into inside battery speed, thereby sour efficient is annotated in influence.Sour efficient is annotated in order to improve by manufacturer at present, directly the funnel height is increased, and increases the volume of funnel, and electrolyte is all put into funnel, lets it infilter into battery down naturally then.This way has increased cost, and the top heavy situation appears in funnel simultaneously, in handling process, leaks acid and topples over easily.
The acid of employing vacuum impregnating needs relevant devices such as configuration vacuum impregnating acid machine, have high input, and production process expends the energy; Adopt the normal pressure formula that pours into to annotate acid, in annotating sour process, have air-resistance phenomenon, sour efficient is annotated in influence, occurs leaking the few sour phenomenon of acid easily, influences battery quality.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of and reduce production costs, improve the sour efficient of notes, and the good lead acid accumulator of security reliability is annotated sour funnel.
The technical scheme of the utility model is: the improvements that lead acid accumulator is annotated sour funnel are to be provided with the exhaust passage that is communicated with the upper and lower port position in this funnel.
Further scheme is: said exhaust passage is the blast pipe that is attached to the funnel inwall; Said blast pipe is a pvc pipe; The bending 180 respectively of the upper and lower end of said blast pipe
0After be affiliated to upper edge and lower edge at funnel; Said exhaust passage is to be located at the inner pipeline of hopper side walls; The lower port of said pipeline is located at the side of the bottom of funnel.
This funnel is used for the normal pressure of storage battery and annotates acid, and inside battery gas is discharged, and avoids air-resistance phenomenon, annotates sour efficient thereby improve.The lower port of exhaust passage is located at side, funnel bottom, can also effectively discharges the gas in the top cover endoporus.This funnel is made simple, and easy to use, less investment can reduce the battery production cost, and security reliability is good.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the another kind of structural representation of the utility model.
Embodiment one: as shown in Figure 1, the blast pipe 1 that adopts PVC to make is placed on and annotates sour funnel 3 inside, and the upper end hangs over annotates sour funnel upper edge, and the lower end was turned the sour funnel of notes lower edge and extended upward, and the exit is lower than bayonet socket 2 positions.Before annotating acid, above the funnel bayonet socket, place a ring-shaped rubber pad, funnel is connected through bayonet socket with battery case loam cake acid-filling mouth, make and annotate sour funnel and the sealing of battery case acid-filling mouth.Add quantitative electrolyte from annotating sour funnel top, electrolyte flows into inside battery through the funnel lower port, and inside battery gas is discharged through blast pipe 1, thereby solves the vapour lock problem.
Embodiment two: as shown in Figure 2, in annotating sour funnel 5 sidewalls, form a pipeline 4, and the port of pipeline 4 is in the funnel upper edge, and lower port is in side, funnel bottom.The course of work is with example one.
