The utility model discloses a kind of casting magnesium alloy surface treatment equipment, belong to metal surface treatment technical field, its technical scheme main points include rack, the right side of the rack is provided with controller, the inside of the rack is provided with conveying structure, the front side and the back of the top of the rack are provided with preheating structure and drying mechanism respectively, the application is by setting conveying structure and drying mechanism, after conveying structure can realize the continuous conveying of batch in order while carrying workpiece, satisfy batch production demand, the even flow wind scooper in drying frame makes the hot air generated by electric heating disc cylinder evenly blow to workpiece, recovery bucket collects unsaturated hot air, after monitoring filtration by hygrometry filter structure, by suction fan is extracted again and is transported to electric heating disc cylinder to carry out recycling, improve hot air utilization, reduce energy consumption, second temperature sensor real-time monitoring temperature ensures drying stability, solve the existing equipment hot air utilization low, energy consumption is big, the problem of low efficiency.

The invention discloses a long-circulation lithium metal battery carbonic ester-based electrolyte as well as a preparation method and application thereof, and belongs to the technical field of lithium battery electrolytes. The carbonic ester-based electrolyte of the long-circulation lithium metal battery comprises the following components: lithium salt, a solvent and a saturated hydrocarbon additive, the solvent is fluoroethylene carbonate, methyl ethyl carbonate and fluoroether. According to the method, a polarity regulation and control strategy is proposed for the first time, the hydrocarbon additive is introduced into the fluorine-containing ether solvent and serves as a weak solvation medium, the polarity of the carbonic ester-based electrolyte is reduced, non-polar saturated hydrocarbon is successfully introduced into the electrolyte on the basis of the principle of similar miscibility, and the problem of bright phase separation is solved; the non-sacrificial electrolyte can significantly reduce the occurrence of side reactions in the electrolyte, and realizes long-term stable circulation of the lithium metal battery.
