Abstract
The invention relates to a device for producing nano-scale high-purity zinc powder by a distillation method. The device is characterized by consisting of a continuously-fed inductive electric heating crucible distillation furnace, a reflux plate, a high-temperature overheat plate, a zinc powder condenser and a closed water cooling tower. A metal zinc ingot is smelted by a smelting crucible to form smelted metal zinc which absorb energy in a distillation crucible for vaporization and distillation, the zinc steam enters the reflux plate so as to remove high-boiling-point purities, the pure zinc steam enters the overheat plate to carry out secondary concurrent heating, overheat zinc steam of which the boiling point higher than that of zinc directly enters the zinc powder condenser to carry out quenching to produce zinc powder which contains little micron-scale high-purity zinc powder and vast majority of nano-scale high-purity zinc powder, wherein the granularity of the produced zinc powder can be controlled within 50nm-100nm, and the purity of the produced zinc powder is up to over 99.999 percent; the zinc powder can be continuously produced by uniform feeding without pollution, the energy consumption is low and the automation degree is high.
Description
Technical field
The present invention relates to a kind of metal melting equipment, 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 object of the invention is in order to overcome above-mentioned weak point, and provide a kind of product purity high, 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 used in the present invention 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 present invention 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.
