Problems solved by technology

At present, in the production process of the storage battery in the prior art, it is necessary to fill the battery with electrolyte. The general method is to directly inject the liquid, which has the following defects: because the electrolyte is relatively viscous, the absorption of the electrolyte is slow. The electrolyte absorption in the plate group is not uniform, so it is not possible to quickly inject the liquid. Rapid liquid injection often causes the electrolyte added to the battery to overflow, and the uneven absorption of the electrolyte will lead to quality problems of the battery, which is a waste of electrolyte. cause greater economic loss

Embodiment 2

[0027] Embodiment 2: Compared with Embodiment 1, the difference lies in that the method of rapid liquid injection and uniform liquid injection is different, and the rest are the same.

[0028] see Figure 3~6 , including the electrolyte tank 1 and the liquid injection pipe 2, the side wall of the liquid injection pipe 2 is provided with at least four through-hole groups 103, and the through-hole groups 103 are more distributed, and the coverage is wider. The through hole group 103 includes the No. 2 through hole 104, the No. 3 through hole 105 and the No. 4 through hole 106 from top to bottom. The diameter of the No. 2 through hole 104 is smaller than the No. 3 through hole 105. The diameter of the hole 105 is smaller than the fourth through hole 106, and the bottom surface of the liquid injection pipe 2 is also provided with a fifth through hole 107. The through-holes in the through-hole group 103 are distributed from top to bottom, and the upper part is smaller and the lowe...

Embodiment 3

[0033] Embodiment 3: Compared with Embodiment 1, the difference lies in that the method of rapid liquid injection and uniform liquid injection is different, and the rest are the same.

[0034] see Figure 7 and Figure 8 , including an electrolyte tank 1 and a liquid injection pipe 2, a spiral piece 201 is fixed inside the liquid injection pipe 2, and a conical liquid collection bucket 202 is fixed on the upper end of the spiral piece 201. The spiral piece 201 can transport the electrolyte to the pole plate group in a rotating manner, so that the pole plate group can receive the electrolyte evenly. The liquid collecting bucket 202 transports all the electrolyte to the upper interface of the spiral sheet 201 to prevent the electrolyte from directly sliding down from the gap of the spiral sheet 201 , thereby affecting the use effect of the spiral sheet 201 .

[0035] The spiral sheet 201 is coated with an anti-sticking agent. It prevents the electrolyte from adhering to the s...

Embodiment 4

[0039]Embodiment 4: Compared with Embodiment 1, the difference lies in that the method of rapid liquid injection and uniform liquid injection is different, and the rest are the same.

[0040] see Figure 9 and Figure 10 , comprising an electrolyte tank 1 and a liquid injection pipe 2, a cross bar 301 is fixed inside the liquid injection pipe 2, the cross bar 301 is perpendicular to the liquid injection pipe 2, and the cross bar 301 plays a main supporting role. A straight bar 302 vertically fixed to the cross bar 301 is also provided. The straight bar 302 is also parallel to the liquid injection pipe 2. The other end of the straight bar 302 is hinged with a combination piece 303. The combination piece 303 includes at least two The blades 304, the blades 304 are inclined to one side, and all the blades 304 rotate to the same position and can overlap. When the combined sheet 303 is two blades 304, the two blades 304 are symmetrical about the center of the connection point. Th...

Abstract

The invention belongs to a storage battery liquid injection device. A liquid injection device for a storage battery, comprising an electrolyte tank and a liquid injection pipe, a horizontal bar is fixed inside the liquid injection pipe, the horizontal bar is perpendicular to the liquid injection pipe, and a straight bar vertically fixed to the horizontal bar is also provided The other end of the straight rod is hinged with a combined piece, the combined piece includes at least two blades, the blades are inclined to one side, and all the blades can be overlapped when they rotate to the same position. The electrolyte is transported down from the liquid injection pipe, and after contacting the combined plate, the force generated by the impact of the electrolyte on the combined plate makes the combined plate rotate, and the electrolyte is thrown out, and the electrolyte is evenly and quickly transported to the plate group.

Description

technical field [0001] The invention belongs to a storage battery liquid injection device. Background technique [0002] Electrolyte is the most traditional electrolyte, which is obtained by heating GAMMA butyrolactone organic solvent and weak salt capacitor. The cathodes of aluminum electrolytic capacitors in the ordinary sense are all this kind of electrolyte. Electrolyte is the medium used in chemical batteries, electrolytic capacitors, etc., providing ions for their normal work. And ensure that the chemical reactions that occur in the work are reversible. At present, in the production process of the storage battery in the prior art, it is necessary to fill the battery with electrolyte. The general method is to directly inject the liquid, which has the following defects: because the electrolyte is relatively viscous, the absorption of the electrolyte is slow. The electrolyte absorption in the plate group is not uniform, so it is not possible to quickly inject the liqui...
