Abstract
The utility model discloses an acid extracting pipe for a lead acid storage battery. The acid extracting pipe comprises a pipe body with a pipeline, wherein the front end of the pipe body is blocked by an end cap; and at least one acid extracting hole communicated with the pipeline is formed in a pipe wall at the front end of the pipe body. Through the technical scheme, the acid extracting holes are unlikely to be blocked, and remaining acid amount after acid extraction can be accurately controlled through the acid extracting holes in both sides of the pipe wall, so that the consistency of the remaining acid amount in each single grid of the battery after acid extraction is effectively ensured.
Description
Technical field
The utility model relates to acid extracting pipe used when being a kind of lead acid accumulator acid dosing and charging.
Background technology
Valve-regulated sealed lead-acid batteries adopts superfine glass fibre partition board usually, adopts " barren liquor type " design, the loss that realizes slowing down moisture in electrolyte by the oxygen composite principle.Therefore, valve-regulated sealed lead-acid batteries must accurately be controlled the acid amount in single lattice battery after acid dosing and charging, and the suction acid saturation of dividing plate is guaranteed in 95% left and right.Usually adopt two kinds of methods to control the dividing plate saturation in production, a kind of is the accurate quantification acid adding, and the charging rear bulkhead is inhaled sour saturation and just reached requirement, no longer takes out acid after charging, and common compacted accumulator generally adopts this mode; Another kind is excessive quantitative acid dosing, also retains excessive mobile acid in cell negative terminal after charging, and the acid that needs to flow is taken away and just can be made dividing plate obtain required suction acid saturation, and electric bicycle batteries and middle large density battery adopt this mode usually.
Adopt the battery of excessive quantitative acid dosing and charging just to relate to the problem of taking out acid, the method that generally adopts at present is to adopt constant voltage charge in the battery charging later stage, or adopt a very little electric current to carry out constant current charge, then directly take out acid with common plastic tube, the free acid of each single lattice in battery is drained.Because the suction inlet of acid extracting pipe front end is the plane of a circle, and the direct parallel contact of utmost point group's upper surface in this plane suction inlet and battery, easily blocked and affect flow velocity, after this can cause taking out acid, each single lattice acid is measured inhomogeneous.And, take out acid action time of staying length difference, taking out the acid amount also can be different.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of lead acid accumulator acid extracting pipe, inhales sour hole and is difficult for blockedly, has effectively guaranteed to take out the consistency of each single lattice residual acid amount of battery after acid.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the lead acid accumulator acid extracting pipe, comprise the body with pipeline, the front end of described body is blocked by end cap, and the front end tube wall of described body is provided with the suction acid hole of at least one and described pipeline communication.
As preferably, the front end tube wall of described body is provided with two coaxial suction acid holes with described pipeline communication.
As preferably, the profile of described end cap is hemisphere.
As preferably, be provided with a bulge loop outside the middle part of described body.
The utility model has been owing to having adopted technique scheme, inhales sour hole and is difficult for blockedly, and can accurately control the residual acid amount of taking out after acid by the suction acid hole of tube wall both sides, effectively guaranteed to take out the consistency of each single lattice residual acid amount of battery after acid.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
Illustrated in figures 1 and 2 is the utility model lead acid accumulator acid extracting pipe, comprises the body 1 with pipeline 11, and the front end of described body is blocked by end cap 2, and the front end tube wall of described body is provided with two coaxial suction acid holes 12 with described pipeline communication.The profile of described end cap 2 is hemisphere.The outside, middle part of described body is provided with a bulge loop 13.
The suction acid pore structure of acid extracting pipe front end is designed to from two side draught acid rather than from mouth of pipe suction acid.The height of two side holes position will be decided according to the concrete sour mode of taking out, and different takes out sour charging voltage, and the position, hole is highly different.The transparent acidproof plastic material of the general employing of acid extracting pipe.
The shape of end cap 2 will be designed to circle or other are pointed, because sour kettle and battery acid adding mouth interface have a step usually, easily blocks acid extracting pipe, is designed to circle or other just can make acid extracting pipe be inserted in battery from sour kettle smoothly after pointed.Other chromatic colours different from acid extracting pipe main body color will be made if not integrally formed with acid extracting pipe in this termination, check conveniently whether the termination comes off or damage.
Acid extracting pipe back segment diameter is different from leading portion, and back segment is bigger, and between the section of front and back, the outside has a bulge loop to be used for the location, and when adopting many acid extracting pipes to be used in combination, this bulge loop just can guarantee that the extension elongation of each root acid extracting pipe from jig is all consistent.
Inhale sour hole and change both sides into from front end, inhale sour Kong Buhui blocked, and, when acid solution is pumped down to the suction acid hole of both sides when following, inhaling sour hole will air amount, and inhaling acid will stop automatically, even continue to take out acid, the residual acid amount can not change yet, and so just can effectively guarantee to take out the consistency of rear each the single lattice residual acid amount of battery of acid.This structure also has another kind of effect, can select to take out arbitrarily exactly the acid period in charging process, because this acid extracting pipe can not drained acid solution, but every single lattice all remain with the acid solution of same liquid level, and the acid solution of these reservations finishes and will sink after standing a period of time and do not have a free acid in battery charging.The height of this residual acid amount can be controlled by the height and position in two side draughts acid holes.
