Description

Technical Field

[0001] The utility model relates to the technical field of vacuum distillation furnace equipment, in particular to a vacuum distillation furnace for zinc and tin recovery. Background Art

[0002] The zinc-tin vacuum distillation furnace is a main equipment specially used for separating and recycling waste zinc, tin and other metal materials under high-temperature vacuum environment. By heating the waste materials, the metal components evaporate and condense in the condenser, thereby realizing the separation and purification of the metal components. This equipment plays an important role in the waste metal recycling industry, helping to effectively recycle and reuse metal resources and realize sustainable resource utilization and environmental protection.

[0003] The current zinc-tin vacuum distillation furnace uses a feeding trolley to feed materials, that is, the feeding trolley filled with raw materials is pushed into the distillation chamber. When the zinc in the raw materials in the feeding trolley is distilled out, tin ingots are formed in the feeding trolley. The feeding trolley is then pushed out and pushed back into the feeding trolley filled with raw materials. The current feeding trolley is mainly pushed manually using long rod tools. This method is not only labor-intensive, but also the inside of the zinc-tin vacuum distillation furnace is still high in temperature after the distillation is completed. There is a risk of scalding by manually pushing the feeding trolley, which has certain safety hazards. Utility Model Content
