Description
Technical field
The utility model relates to the vacuum sublimation purification furnace, is particularly useful for metal or nonmetallic distillation and purifies.
Background technology
Metal distillation purification principle is to utilize the vapour pressure difference that material produces under the vacuum heating conditions, and the metallic vapour that vapour pressure is high is separated by specific condensing mode.The purification furnace of present domestic employing is the vertical vacuum subliming furnace of simple function, and this vertical vacuum subliming furnace has only a sublimation chamber, and its crystallizer is located at the sublimation chamber top.After distillation finishes, must open bell and take out crystal metal, put into other crucible furnace again and melt casting ingot-forming again, cause secondary pollution easily like this.Owing to limited by crystallizer, this stove can not be done greatly, and output generally is no more than 200 kilograms; Crystallizer is simple, and temperature can not accurately be controlled, and can not the metal separation that vapour pressure is close go out, and can not directly melt casting ingot-forming to the metal that distillation is come out.
The utility model content
The purpose of this utility model is to provide a kind of compact conformation, and output is big, and the control temperature is accurate, and crystallization effect is good, and collection distillation crystallization and thawing are the vacuum sublimation purification furnace of one.
Vacuum sublimation purification furnace of the present utility model, comprise subliming furnace flue and body of heater, the vavuum pump that links to each other with subliming furnace, described subliming furnace flue is a horizontal circular tank body, the tank body middle part is provided with the plate washer that tank body is divided into sublimation chamber and crystallisation chamber, sublimation chamber one end is provided with the fire door that thermocouple is housed, and crystallization chamber is provided with the cold plate that polylith interleaves up and down, and its termination is provided with pump-line; Described subliming furnace body of heater and crystallisation chamber body of heater are the electrical heating body of heater, be provided with the cooling air passage between electrical heating body of heater and the flue, the crystallisation chamber bottom is provided with bleeder valve, is respectively equipped with exhaust outlet on sublimation chamber and the crystallisation chamber top body of heater, is respectively equipped with intake stack on the body of heater of below.
Described pump-line outside is provided with cooling jacket, and inside is provided with the cold-trap as the condensation low melting point.
Vacuum sublimation purification furnace of the present utility model, subliming furnace is for to separate horizontal type structure with sublimation chamber and crystallisation chamber, crystallisation chamber flue and be connected cold plate on the flue as crystallizer, adopt electrical heating and cooling air mode control sublimation chamber and crystallisation chamber temperature on sublimation chamber and crystallisation chamber external furnace body, distillation end post crystallization chamber can be used as heavily melts crucible furnace with the metal or the cast of nonmetal heating and melting of purifying.Be located at metal or nonmetal separating that the cold-trap of pump-line inside can be close with vapour pressure, it is simple in structure, compact and reasonable, and output is big, and the control temperature is accurate, and crystallization effect is good, has practicality widely.
