Specific embodiment
Below by specific embodiment and in conjunction with attached drawing, invention is further described in detail.
Fig. 1 shows a kind of illustrative, typical lead-acid accumulator electrolyte evenly mixing device of the present invention.Its basic structure
Including storage tank 1, inflow entrance 2, outflux 3 and deflector 4.Storage tank 1 is by the opposite long side wall 7,7' of bottom wall 5 and two and two phases
Pair short side wall 6,6' is enclosed, and inflow entrance 2 is located at the first short side wall 6, outflux 3 be located at bottom wall 5 close to the second short side
At the position of wall 6', deflector 4 is parallel to the second short side wall 6' and extends from the lower surface of bottom wall 5, so that outflux 3 is located at second
Between short side wall 6' and deflector 4.The area of outflux 3 is designed to the area greater than inflow entrance 2.
As shown in Figure 1, inflow entrance 2 is two circular holes to connect with the bottom wall 5 of storage tank 1, outflux 3 is short with second for one
The rectangular opening that side wall 6' and deflector 4 all connect, and the second short side wall 6' extends from bottom wall 5 to the length direction of deflector 4
A certain distance.In fig. 1 and 2, it is shown that the second short side wall 6' is more wider than the first short side wall 6, i.e., storage tank 1 is short second
Width at side wall 6' is slightly larger than the rest part of storage tank 1.But the width of the second short side wall 6' can also be with 6 phase of the first short side wall
Together.
Fig. 3 shows that illustrative, the typical evenly mixing device of Fig. 1 is mounted on the state in the battery compartment of lead-acid accumulator.
The evenly mixing device is firmly installed in battery compartment by secure component (not shown).The stabilizing components can be and store up
Two long side walls 7 of slot 1, the integrally formed gripping member of 7', removably to detain on the side wall for riding over battery compartment.
As shown in figure 3, the lower surface of the bottom wall 5 of storage tank 1 just contacts liquid level of electrolyte.Although under the bottom wall 5 of storage tank 1
Surface can also be located at the lower section of liquid level of electrolyte, i.e., storage tank 1 immerses in electrolyte, but storage tank 1 should be had by electrolyte, i.e.,
Should not be when in a horizontal state in liquid level of electrolyte, namely it is flat in the automobile for being mounted with the lead-acid accumulator with the evenly mixing device
Surely when driving, electrolyte has entered in storage tank 1.If so, which cannot accelerate (such as to open in automobile
It is dynamic), slow down (such as brake), go up a slope, descending or while turning to play the role of mixing electrolyte, reduce electrolyte stratification.
As shown in figure 3, the length of the long side wall 7' of storage tank 1 is the half of the length of battery compartment.The long side wall 7,7' of storage tank 1
This length so that the electrolyte of battery compartment inclines in the acceleration of automobile, deceleration, upward slope, descending or steering procedure
When oblique, the liquid level middle line of inclined electrolyte is substantially overlapped with the intersection of the first short side wall 6 of storage tank 1 and bottom wall 5.It is this
Length of the situation than the long side wall 7,7' of storage tank 1 is greater than or equal to the case where half of the length of battery compartment more suitable for automobile
Most of acceleration, deceleration, upward slope, descending turn to situation.
As shown in figure 3, when evenly mixing device is mounted in the battery compartment of lead-acid accumulator, the bottom of the separate storage tank 1 of deflector 4
The distance between that one end and the bottom of battery compartment of wall 5 are less than a quarter of lead-acid accumulator electrolyte depth, actually
It the relatively bottom of battery compartment can be to the greatest extent when this helps to guide the electrolyte in storage tank 1 to flow back to battery compartment by outflux 3
The bottom of battery compartment may be flowed to, so that the higher electrolyte of the density of battery compartment bottom is forced to flow to the top of battery compartment, with
The lower electrolyte mixing of the density on battery compartment top, so that density of electrolyte is uniform, prevents electrolyte stratification phenomenon.
As shown in figure 3, the second short side wall 6' extends a certain distance from bottom wall 5 to the length direction of deflector 4, extension
Distance is less than a quarter of lead-acid accumulator electrolyte depth.Second short side wall 6' is from bottom wall 5 to the length direction of deflector 4
Extend it is not necessary to, but when the electrolyte that facilitates in storage tank 1 of the extension flows back to battery compartment by outflux 3, flowing out
Obtain better water conservancy diversion at mouthfuls 3, prevent the electrolyte for flowing back to battery compartment from prematurely mixing with the electrolyte in battery compartment and cannot
The higher electrolyte of the density of battery compartment lower part is forced to flow to the top of battery compartment well.
Fig. 4 is state of the display lead-acid accumulator shown in Fig. 3 for being equipped with evenly mixing device in automobile up slope, Cong Zhongke
To understand the working principle of the evenly mixing device.As shown in figure 4, be transversely mounted when automobile up slope (i.e. the length direction of battery compartment with
The length of wagon direction of automobile is parallel) lead-acid accumulator tilt backwards, the electrolyte in battery compartment can keep horizontality, but
For battery compartment bottom (or top) plane be have occurred it is inclined.Since evenly mixing device is fixedly mounted on battery compartment
The left side (as shown in Figure 4), the electrolyte of run-off the straight can be flowed into storage tank 1 by the inflow entrance 2 of evenly mixing device in battery compartment,
Inclined liquid level is gradually also formed in storage tank 1.Restore after automobile up slope it is flat when driving, lead-acid accumulator restore it is horizontal
State, the electrolyte in battery compartment is horizontal, in storage tank 1 electrolyte for battery compartment bottom (or top) plane
It is also horizontal relative to battery compartment bottom (or top) plane.But some electricity have been flowed into from inflow entrance 2 when due to inclination
Liquid is solved, the liquid level of the electrolyte in storage tank 1 is higher than the liquid level of the electrolyte in battery compartment at this time, inside and outside storage tank 1
The difference in height of electrolyte.The difference in height leads to pressure difference, and the electrolyte in storage tank 1 is forced to flow back to battery compartment by outflux 3.By
It is designed to the area greater than inflow entrance 2 in the area of outflux 3, although the electrolyte in storage tank 1 understands some by stream
Entrance 2 flows back to battery compartment, but most electrolyte can flow back to battery compartment by outflux 3.Battery compartment is flowed back to from outflux 3
Electrolyte passes through the water conservancy diversion of deflector 4, battery compartment bottom is directed into, to force the higher electrolysis of the density of battery compartment bottom
Liquid flows up, and mixes with the lower electrolyte of the density on battery compartment top, so that the density of electrolyte in battery compartment be made to tend to
Unanimously, electrolyte stratification phenomenon is avoided.
When the gradient of automobile up slope is larger, inclined electrolyte can not only be flowed by the inflow entrance 2 of evenly mixing device and be stored up
Slot 1, the first short side wall 6 that can also cross the storage tank 1 of evenly mixing device flow directly into storage tank 1.When automobile restore it is flat when driving, storage
Liquid level of electrolyte in slot 1 is higher than the liquid level of electrolyte outside storage tank 1, as described above because difference in height, pressure difference there are due to promote
Electrolyte mixes.
Although the flow condition of electrolyte when Fig. 4 shows automobile up slope, accelerate (such as starting) but it is also suitable for automobile
When situation.If evenly mixing device is mounted on the right of battery compartment in Fig. 4, then be suitable for automobile downhill or slow down (such as
Brake) situation.If lead-acid accumulator is longitudinally mounted on automobile (the i.e. length of wagon of the length direction and automobile of battery compartment
Direction is vertical), then when motor turning, the inclination that electrolyte occurs may also lead to electrolyte difference in height, pressure difference inside and outside storage tank 1,
Finally electrolyte is promoted to mix.
Fig. 5 is shown in lead-acid accumulator using the electrolyte mixed effect of the evenly mixing device of Fig. 1.At the bottom of battery
Portion, middle part, top add three kinds of different densities electrolyte, imitating electrolytic fluid lamination.Battery is placed in experiment rocker,
The battery that simulation is mounted on automobile situation of run-off the straight with automobile climb and fall.Swing angle is 13 degree, and waving number is 5
It, waves altogether 150 times second for 1 time.Often wave top density of 10 surveys.After waving 150 times, the close of top electrolyte is measured
Degree is 1.275g/ml, is significantly improved compared with its initial density 1.206g/ml.In contrast, mixing dress is used no
In the comparative test set, after waving 150 times, the density for measuring top electrolyte is 1.218g/ml, with its initial density
1.205g/ml little compared to improving.The experiment proves that evenly mixing device of the invention has good effect for mixing electrolyte.
