Description

Technical Field

[0001] The utility model relates to the technical field of lead ingot casting, in particular to a lead electrolytic quantitative casting device. Background Art

[0002] The lead used for lead electrolysis is generally produced by a casting production line. In the prior art, the process of casting lead ingots of the finished casting line is to first output the molten lead in the casting pot to an insulated box, and the molten lead flows from the insulated box to the diverter, and then is cast into the mold by the diverter to form a lead ingot. The diverter is driven by the contact with the edge of the mold after the casting line is started. However, this casting method makes it difficult to ensure the flow rate of the molten lead, and it is difficult to ensure that the weight of each lead ingot is within the error range. In addition, when the molten lead is cast, splashes and impacts are easily generated, which makes it easy for burrs to form on the surface of the lead ingot, resulting in reduced quality of the output electric lead products, which is not conducive to production. To this end, we propose a quantitative casting device for lead electrolysis. Utility Model Content
