Electrical heating crucible type low-boiling-point metal distillation furnace capable of continuously feeding material

Abstract

The invention relates to an electrical heating crucible type low-boiling-point metal distillation furnace capable of continuously feeding material. The distillation furnace is characterized by comprising a distillation crucible equipped with an upper cover and a melting crucible; a feeding hole and a steam output guide pipe are arranged on the upper cover of the distillation crucible; the lower end of the feeding hole is connected to the upper end opening of the melting crucible; a discharging hole is formed at the bottom of the melting crucible; and the distance from the bottom of the crucible to the upper edge of the upper cover of the distillation crucible is 300-350mm. Solid material is directly added into the melting crucible; after being molten, the material directly enters the distillation crucible to be vaporized and distilled; low-boiling-point metal steam enters a condenser through the steam output guide pipe and is condensed into liquid or powder; uniform feeding, continuous melting and distilling can be carried out in the production process; low-boiling-point metal steam is continuously produced; and the electrical heating crucible type low-boiling-point metal distillation furnace disclosed by the invention has the advantages of continuous production, no pollution, low energy consumption, and convenient operation, can produce high-purity products and is applied to distillation of metal material with the boiling point being lower than 1500 DEG C at normal pressure.

Description

technical field [0001] The invention relates to a metal distillation equipment, in particular to an electric heating crucible type low-boiling metal distillation furnace capable of continuous feeding. Background technique [0002] At present, the distillation equipment used in the metal distillation process mainly includes tray distillation furnaces, muffle distillation furnaces, and crucible distillation furnaces. The tray-type distillation furnace needs to be equipped with a melting furnace. The material to be distilled is required to have good fluidity, and the material with high impurities cannot be distilled, and the furnace cannot be stopped midway. The muffled distillation furnace can continuously feed and distill. It also requires the material to be distilled to have good fluidity. It cannot distill materials with high impurities and cannot stop the furnace midway. The crucible distillation furnace can handle complex materials, but it cannot continuously feed and di...

AI Technical Summary

Problems solved by technology

The crucible distillation furnace can handle complex materials, but it cannot continuously feed and distill, and the operation is inconvenient

The heating methods used in these distillation furnaces are gas heating, or natural gas heating, or coal heating, which have low energy efficiency, serious environmental pollution, and poor operating conditions
