Detailed Description
The utility model will be further described with reference to the accompanying drawings in which:
as shown in fig. 1 and fig. 2, the lead-acid storage battery cell with acid circulation and flow guide functions comprises a cell body 1 with a notch at the top, wherein the cell body 1 is provided with a partition wall dividing the interior into 6 single cells, and the 6 single cells are distributed in a 2 x 3 structure. And around each single lattice in the tank body 1, about 120 acid circulation draft tubes 2 with the diameter of 1-3 mm are arranged. The acid circulation draft tube 2 is of a hollow structure.
As shown in fig. 3, the acid circulation draft tube 2 extends vertically.
As shown in fig. 4 and 5, the bottom 3 of each acid circulation draft tube 2 is flush with the top 5 of the draft tube 2, and the top is not lower than the electrolyte level 6. The distance between the bottom 3 of the guide pipe and the bottom 4 of the tank body is about 5-10 mm, and the distance between the top 5 of the guide pipe and the liquid level of the electrolyte is 6 about 5-10 mm.
According to the utility model, according to the principle of capillary action, bottom electrolyte 7 rises from the bottom 3 of the draft tube along the wall of the draft tube and flows out from the top 5 of the draft tube, and the top 5 of the draft tube is slightly higher than the liquid level of the electrolyte by about 5 mm. Due to the working state of the storage battery, electrolyte layering and other reasons, the density of electrolyte 7 at the lower part of the storage battery is higher than that of electrolyte 8 at the upper part, the electrolyte 7 at the lower part of the storage battery reacts more intensely in the charging and discharging processes, a large amount of gas is continuously generated, thrust is generated at the bottom, the lower electrolyte 7 is pushed to rise from the bottom 3 of the guide pipe along the pipe wall of the guide pipe and flow out from the top 5 of the guide pipe, and therefore a cycle is achieved; meanwhile, in the charging and discharging process, the lower electrolyte 7 is consumed more, so that the density of the lower electrolyte 7 is locally and instantaneously reduced, and more heat energy is released, so that the temperature of the lower electrolyte 7 is increased, and the lower electrolyte 7 is easier to rise from the bottom 3 of the honeycomb duct along the wall of the honeycomb duct.
The lower electrolyte 7 flows to the upper part along the circulating guide pipe 2, so that the densities of the upper electrolyte 8 and the lower electrolyte 7 are more uniform, and the phenomenon that the lead-acid storage battery is difficult to discharge or cannot discharge in the later use stage is improved. The cell body structure enables the cell to be in an acid cycle in a working environment, effectively improves the density layering phenomenon of the electrolyte and prolongs the service life of the cell. The circulating flow guide function is solidified in the battery jar, and the battery jar is not required to be independently installed, so that the structure is simple; the honeycomb ducts are uniformly distributed in the tank body, the area of the honeycomb ducts is large, the flow guiding effect is good, and the acid liquid density distribution is more uniform.
