Abstract
The utility model provides a crude zinc vacuum distillation furnace, using that: the evaporation pot is the center, which is connected with a zinc condenser, the zinc condenser is connected with a cadmium condenser, both the lower ends of the zinc condenser and the cadmium condenser are provided with annular liquid collecting grooves whose upper ends are covered with non-return caps, a pumping tube is connected on the cadmium condenser, the lower end of the cadmium discharging tube connected with the cadmium collecting groove is inserted in the cadmium liquid seal pot. The lower end of the evaporation pot is respectively connected with the crude zinc feeding tube, the refined zinc discharging tube, and the residue discharging tube, the lower end of each tube is inserted into the corresponding seal pot respectively. The utility model has the advantages of reasonable and compact structure design, small size, few area occupied, and little investment, which not only simplifies the zinc smelting process, but also can effectively reprocess the regenerated zinc, thus obtaining high-grade refined zinc. The operation is convenient, the producing efficiency is high.
Description
Technical field
The utility model relates to a kind of non-ferrous metal metallurgy equipment, especially a kind of crude zinc vacuum distillation furnace.
Background technology
The extraction of former tutanag metal is to smelt and get from zinc sulfide concentrates mostly.Its smelting technology flow process is broadly divided into " pyrogenic process " and " wet method " two big classes.At first from the zinc sulfide concentrates desulfurization with roasting technique, product of roasting is calcining, with calcining and reductive agent---and coal mixes, and places special metallurgical furnace interior (horizontal jar or perpendicular jar) muffle Heating temperature distilling more than 1200 ℃.This is the traditional method of pyrometallurgy of zinc.But there are many shortcomings in pyrometallurgical smelting: low as heat utilization efficiency, energy consumption is big, metal recovery rate is low, quality product is low, equipment is huge, stove has a few floor height, and main is not have good method of refining and equipment to cooperate, preparation operation complexity before the refining.So replaced by " wet method " zinc metallurgy.
So-called " wet method " zinc metallurgy is exactly with gained calcining behind the zinc sulfide concentrates desulfurization with roasting technique, leaches with dilute sulphuric acid, make zinc become zinc sulfate to enter solution, after the filtration, leach liquor adds zinc powder again and purifies, and pumps into electrolyzer feeding direct current after the gained scavenging solution adjustment concentration and carries out electrodeposition and obtain product.The advantage of zinc hydrometallurgy is to obtain high-quality product, might as well fully utilize, and reclaims valuable metal.But shortcoming is the flow process complexity, equipment is huge, labor condition is poor, initial cost is big.General only suitable large-scale smelting enterprise adopts, and some smelting units on a small scale are difficult to adopt.
There are many regenerated zincs to need the freshening utilization in the society at present.As electroplate back remaining anode scrap, impurity enrichment relatively, all be not suitable for refining again these materials with traditional pyrogenic process or wet method now.In addition, the scrap stock that large-scale mine is remaining are pyrometallurgical smeltings as many, and the products obtained therefrom quality is all low.Handle to obtain high-grade smart zinc with assorted the same a kind of effective method of refining and the equipment of all needing of zinc of regenerated.
Summary of the invention
The purpose of this utility model provides a kind ofly uses the vacuum distilling zinc concentrate, and matching used with it crude zinc vacuum distillation furnace, and this furnace structure is simple and direct, and volume is little, and is easy to operate, adopts this equipment can be purified to about 95% crude zinc 99.9% smart zinc product.
Technical solution adopted in the utility model is:
With the evaporating pan is the center, connect zinc condenser in the above, connect the cadmium condenser above the zinc condenser, the lower end is equipped with the annular hydrops groove that the non-return cap is stamped on top in zinc condenser and the cadmium condenser, extraction pipe is connected on the cadmium condenser, and insert in the cadmium fluid-tight pot its lower end of cadmium vent pipe that connects under the cadmium hydrops groove; The evaporating pan bottom connects crude zinc feed-pipe, smart zinc vent pipe and residue vent pipe respectively, and each is managed the lower end and all inserts respectively in the corresponding fluid-tight pot.Difference tubular stinger heart poker in the middle of each feed and exhaust tube.Be welded with temperature control airduct and condensing fin in the zinc condenser.Melting tank connects each fluid-tight pot respectively by pipeline.
The utility model reasonable in design compactness, volume is little, and floor space is little, and less investment had not only been simplified zinc metallurgy process but also effective freshening regenerated zinc, obtained high-grade smart zinc.Easy to operate, the production efficiency height.
