Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid batteries, in particular to a composite lead wire mold core heating treatment device. Background Art

[0002] Lead-acid battery was invented by Frenchman Plante in 1859. It is mainly composed of positive plate, negative plate, electrolyte, separator, electrolytic cell, battery cover, pole, etc. The main active ingredient of the positive electrode is lead dioxide, the main active ingredient of the negative electrode is lead, and the electrolyte is sulfuric acid solution. The chemical reactions involved in its discharge are as follows:

[0003] Discharge positive electrode: PbO2+4H++SO4 2- +2e - =PbSO4+2H2O;

[0004] Discharge cathode: Pb+SO4 2- -2e - =PbSO4;

[0005] Lead-acid batteries have good charging and discharging performance, are safe and stable, and are cheap. They are currently widely used in electric bicycles, automobiles, USP, energy storage and other fields. In recent years, with the vigorous development of new energy and energy storage industries, lithium, sodium, fuel cells and other technologies have developed rapidly. In order to further enhance the market competitiveness and influence of lead-acid batteries, high specific energy and long life have become the inevitable trend of lead-acid batteries in the future. The use of new materials, new processes and new technologies has become a key point that lead-acid batteries urgently need to break through. Composite lead wire is an efficient and high-value application of new materials and new processes in lead-acid batteries. Composite lead wire is generally made by passing high-conductive fiber materials through the mold core and then extruding the lead material through an extrusion device for one or more coatings. During the production process, due to various reasons, the composite lead wire will break and remain in the mold core.

[0006] The traditional processing method is to disassemble the mold core and heat it with an acetylene gas cutting torch to melt the lead wire in the mold core and let it flow out after cooling and cleaning. Continued use of this method is very likely to cause deformation of the mold core. When the mold core is used again, the quality stability and consistency of the lead wire produced are poor. Another processing method is to put the mold core into a crucible and heat it in a muffle furnace. This method not only has high energy consumption, but the lead wire in the mold core is also difficult to clean at one time. Utility Model Content

[0007] In view of the above analysis, the utility model aims to provide a composite lead wire core heating treatment device to solve at least one of the problems that the prior art method easily causes the core to deform, the quality of the lead wire produced when the core is reused is unstable, and the treatment efficiency is low.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A composite lead wire mold core heating treatment device, the device comprises a heating mold base and a lead slag collection box, the heating mold base is fixed above the lead slag collection box, the heating mold base is provided with a plurality of heating cavities for heating the composite lead wire mold core, and the heating cavities penetrate the heating mold base.

[0010] Furthermore, the shape and size of the heating chamber are matched with the shape and size of the composite lead wire core, so that the composite lead wire core is clamped in the heating chamber and does not fall off.

[0011] Furthermore, a portion of the composite lead wire mold core is located inside the chamber of the heating chamber, and the lead wire inlet on the composite lead wire mold core is located inside the chamber of the heating chamber.

[0012] Furthermore, a groove is arranged on the inner wall of the heating chamber from top to bottom.

[0013] Furthermore, the groove is arranged corresponding to the lead wire inlet on the composite lead wire mold core.

[0014] Furthermore, the groove is a trumpet-shaped groove, and the opening width of the trumpet-shaped groove gradually decreases from top to bottom.

[0015] Furthermore, the heating mold base and the lead slag collecting box are fixed by bolts.

[0016] Furthermore, a plurality of heating tubes are fixedly arranged inside the heating mold base.

[0017] Furthermore, the heating tube is electrically connected to the control system.

[0018] Furthermore, at least one temperature control probe hole is provided on the heating mold base, and a temperature control probe is provided in the temperature control probe hole.

[0019] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0020] The composite lead wire mold core heating treatment device of the utility model can heat multiple composite lead wire mold cores at the same time. When the composite lead wire remaining in the composite lead wire mold core is heated to the melting temperature of the lead wire, the lead wire begins to melt and flows into the lead slag collection box through the heating chamber. The device of the utility model can clean the lead wire in the mold core, and the cleaned mold core can continue to be used for producing lead wire, thereby improving the production efficiency of the lead wire. The device of the utility model will not destroy the structure of the mold core, and when the mold core is used to produce lead wire again, it will not cause problems such as breakage of the lead wire, and the quality of the lead wire produced again is stable.

[0032] Compared with the prior art, the composite lead wire mold core heating treatment device of the utility model can heat multiple composite lead wire mold cores at the same time. When the residual lead wire in the composite lead wire mold core is heated to the melting temperature of the lead wire, the lead wire begins to melt and flows into the lead slag collection box 2 through the heating chamber 11.
