Abstract

The invention discloses lead-acid storage battery grid production equipment with a good compaction effect and a process thereof. The equipment comprises a preparation furnace, a material conveying pipe, a conveyor, a cooling box, a forming mold, a cooling pipe electric telescopic rod and a compaction plate. According to the invention, metal additives such as selenium, sulfur and arsenic are addedinto a lead-acid storage battery grid alloy; therefore, the corrosion resistance and hardness of the grid of a lead-acid storage battery are effectively improved, the overcharge resistance is improved, the loss of the lead-acid storage battery is greatly reduced, and the problems of thermal cracking, shrinkage cavity and the like of a lead-acid storage battery grid caused by different surface tensions of various metal additives are avoided; the lead-acid storage battery grid is subjected to aging curing in an excellent environment, the interior of an external curing box is dehumidified throughsteam, the dehumidified lead-acid storage battery grid is dried for 2-22 hours, the grid curing effect is good, and the curing quality of the lead-acid storage battery grid is guaranteed; and throughcooperative use of an electric telescopic rod and a compaction plate, rapid compaction of the forming die span is facilitated, and the compaction effect is good.

Description

technical field [0001] The invention relates to lead-acid battery grid production equipment, in particular to a lead-acid battery grid production equipment with good compaction effect and a process thereof, belonging to the technical field of lead-acid battery grid processing. Background technique [0002] A lead-acid battery is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main component of the positive and negative electrodes is lead sulfate. The nominal voltage of a single-cell lead-acid battery is 2.0V, which can be discharged to 1.5V and charged to 2.4V; in applications, six single-cell lead-acid batteries are often connected in series to form a nominally 12V lead-acid battery , There are 24V, 36V, 48V and s...

Problems solved by technology

[0003] Many domestic battery manufacturers also add additives such as selenium, sulfur, and arsenic to antimony-containing grid alloys to improve the corrosion resistance and hardness of the grid, improve overcharge resistance, and reduce battery loss. However, due to various additives The dissolution temperature in lead is different, and its solubility is also different, and the surface tension of various additives is different, which will cause defects such as thermal cracking and shrinkage of the grid; at the same time, the alloy is prepared by each battery manufacturer, and the mold device and production process They are not the same, which leads to the formation of porous, porosity, shrinkage cavity, cracks, broken ribs and other problems in the cast grid, which seriously affects the quality of the grid. Therefore, it is necessary to optimize the grid alloy formula, optimize the alloy casting process, and eliminate the effects of various additives. surface tension to improve the corrosion resistance, mechanical strength and overcharge resistance of the grid. Therefore, we propose a production equipment and process for the lead-acid battery grid with good compaction effect
