Problems solved by technology

[0004] The prior art has the following technical problems: 1. In the prior art, wax sealing cannot be realized immediately after the acid filling is completed, but the acid filling pipe is removed and then the wax is filled, because the sulfuric acid that has been poured into the horizontal battery encounters The air will absorb water, so the concentration of sulfuric acid is prone to decrease; 2. After the acid filling is completed, the mouth of the acid filling pipe is prone to acid dripping. If this is the case for a long time, it will not only cause waste, but also easily corrode external substances and security incident

Embodiment 1

[0035] In order to achieve the above object, the basic scheme of the present invention is as follows:

[0036] The horizontal battery sealing wax method comprises the steps:

[0037] Step 1, material preparation: dilute sulfuric acid and wax;

[0038] Step 2, melting wax: heating the wax in step 1 to form wax in a fluid state, and then stirring continuously;

[0039] Step 3. Prepare sealing wax equipment: figure 1 As shown, the wax sealing device includes a device body with a convex cross-section, and the device body is composed of two cylinders, and the diameter of the upper cylinder is smaller than that of the lower cylinder. A sulfuric acid chamber 1 and a sulfuric acid port 11 for adding sulfuric acid to the sulfuric acid chamber 1 are arranged in the upper cylinder. A wax cavity 2 and a wax filling port 21 for adding wax to the wax cavity 2 are arranged in the lower cylinder, and caps for sealing are provided on the sulfuric acid port 11 and the wax filling port 21 . ...

Embodiment 2

[0053] The difference between this embodiment and embodiment 1 is that, as Figure 6 As shown, the wax sealing equipment also includes a cooling part 6, the cooling part 6 includes a cooling box and a refrigeration pipe located in the cooling box; the cooling box is fixed on the upper surface of the equipment body; the upper end of the push rod 41 extends into the cooling box. It can be further ensured that the push rod 41 can transfer the cold source to the conical cover 4, so that the wax at the conical cover 4 can solidify quickly.

Embodiment 3

[0055] The difference between this embodiment and Embodiment 1 is that an inverted conical cover 4 is provided at the lower part of the acid discharge channel 321; a ring-shaped convex edge 7 is fixed on the edge of the upper surface of the conical cover 4 (such as Figure 7 As shown), the diameter of the annular convex edge 7 is greater than the diameter of the cylindrical channel 3212.

[0056] The upper surface of the conical cover 4 is fixed with an L-shaped push rod 71; the side wall of the acid filling pipe 3 is provided with a strip-shaped sliding port, and the upper end of the L-shaped push rod 71 passes through the strip-shaped sliding port and is fixedly connected with the wax filling pipe 23; The lower end of the acid filling pipe 3 stretches out the wax filling pipe 23, and a return spring 33 is also provided between the lower end of the acid filling pipe 3 and the wax outlet pipe; Thermal layer 5.

[0057] The L-shaped push rod 71 comprises a vertical bar 711 and...

Abstract

The present invention relates to the technical field of battery production, in particular to a method for wax sealing of horizontal batteries, comprising the following steps: Step 1, material preparation; Step 2, melting wax; Step 3, preparing wax sealing equipment; Step 4, tank acid; Step 5 1. Sealing wax; step 6, follow-up processing. This scheme can not only carry out wax sealing immediately after the acid filling is completed; but also can use wax to seal the mouth of the acid filling pipe to prevent sulfuric acid dripping and the like.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to a method for sealing wax of a horizontal battery. Background technique [0002] Horizontal batteries are widely valued by the lead-acid battery industry because of their advantages such as high power, long life, fast charging, sealing and low cost. Especially in power and deep cycle applications, horizontal batteries have shown good performance and It has been successful in electric vehicles and hybrid electric vehicles, and is considered to be a promising new lead-acid battery. [0003] The manufacturing process of the horizontal battery is as follows: lead - lead powder - lead paste - coating - surface drying - splitting - curing and drying assembly - casting and welding - heat sealing of the tank cover - acid filling - sealing wax. The sealing wax in the prior art is generally used to seal the acid filling port of the horizontal battery with wax after the pipeline ...
