Abstract

A device for producing nanoscale high-purity zinc powder through a distillation method is characterized by comprising an induction type electric heating crucible distillation furnace, a backflow disc, a high-temperature overheating disc, a zinc powder condenser and a closed type water cooling tower, wherein materials can be continuously fed to the induction type electric heating crucible distillation furnace. Molten zinc obtained after metal zinc ingots are melted through a melting crucible absorbs energy in a distillation crucible to be vaporized and distillated, zinc steam enters the backflow disc, high-boiling-point impurities are removed, pure zinc steam enters the overheating disc for secondary heating, overheated zinc steam higher than the zinc boiling point directly enters the zinc powder condenser for splat cooling, little part of generated zinc powder is micron-order high-purity zinc powder, most generated zinc powder is nanoscale high-purity zinc powder, the granularity of the zinc powder can be controlled between 50 nm and 100 nm, and the purity is more than 99.999%. Materials can be evenly added, the zinc powder can be continuously produced, production pollution is avoided, energy consumption is low, and the automation degree is high.

Description

The way of distillation is produced nanoscale high-purity zinc powder device
Technical field
The utility model relates to a kind of metal melting equipment, and particularly a kind of way of distillation is produced nanoscale high-purity zinc powder device.
Background technology
At present, what the equipment of production super-fine zinc dust generally adopted is flame-insulating type reverberatory furnace, tower retort, and all, not to pure zinc fume secondary heat patching device, the zinc powder of producing can not reach nanoscale, and energy consumption is high, it is large to pollute, automaticity is low.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned weak point, and provides a kind of product purity high, and energy consumption is low, pollution-free, and the way of distillation that automaticity is high is produced nanoscale high-purity zinc powder device.
For achieving the above object, the technical solution adopted in the utility model is: a kind of way of distillation is produced nanoscale high-purity zinc powder device, it is characterized in that by induction type electric heating crucible retort that can continuous charging, reflux and hyperthermia and superheating dish, zinc powder condenser, enclosed water-cooling tower composition, induction type electric heating crucible retort that wherein can continuous charging comprises the distillation crucible of building upper cover, distillation crucible crucible is external coatedly successively has a high-alumina refractory heat-insulation layer, asbestos layer, coreless induction furnace coil, on cover and have charge door, steam output duct, on the charge door lower end that covers connect fusion crucible upper port, discharge opening is arranged at fusion crucible bottom, at the bottom of crucible, cover along 300mm~350mm apart from distilling on crucible.Backflow and hyperthermia and superheating dish comprise by bottom being that carborundum return tray, top are the tower tray that the overheated dish of graphite is connected, return tray disk body is coated successively outward fire-resistant mud layer, a stainless steel casing, and overheated dish disk body is coated successively outward high-alumina refractory heat-insulation layer, asbestos layer, coreless induction furnace coil, a stainless steel casing.The steam output duct output that distillation covers on crucible is communicated with return tray lower end, and overheated dish upper end is communicated with the charging aperture of zinc powder condenser, the link connection corresponding with enclosed water-cooling tower respectively of the hot water of zinc powder condenser, cold water link.
The utility model is owing to adopting above design, when use, the metallic zinc liquid of metal zinc ingot after fusion crucible fusing absorbs energy vaporization distillation in distillation crucible, zinc fume enters return tray through steam output duct, remove high-boiling-point impurity, pure zinc fume enters overheated dish and carries out secondary concurrent heating, directly enter and in zinc powder condenser, carry out chilling higher than the overheated zinc fume of zinc boiling point, it is the energy that zinc powder discharges that enclosed water-cooling tower is taken away zinc vapor condensing in time, the zinc powder of output seldom part is micron order high-purity zinc powder, the overwhelming majority is nanoscale high-purity zinc powder, product granularity is controlled at 50nm~100nm, purity is up to more than 99.999%, the continuous output of can evenly feeding in raw material, produce pollution-free, energy consumption is low, automaticity is high.
