Description
Technical field
The present invention relates to a kind of brass furnace.
Background technology
Brass is important metallic substance, is widely used.In the process of production and use brass ware, can produce a large amount of brass scrap raw materials, the price that producer processes brass scrap is only 1/10th of its raw material purchase price, and financial loss is very big.In order to control cost, just from brass, extract copper and zinc, sell separately or recycling.
The method of mostly extracting at present copper and zinc from brass is mainly two kinds, a kind of be disclosed as " CN1113520 " as Chinese patent, name is called " Wet-process metallurgy method that reclaims copper and zinc from copper zinc material " described " employing ammonia leaching copper zinc material; then adopt extraction process that copper zinc in leach liquor is separated; the long-pending electrolytic copper of producing of rich copper liquid power transmission; raffinate obtains zinc subcarbonate through ammonia still process, send and calcines to obtain active zinc flower." deficiency that exists of the method is to obtain metallic copper and zinc oxide, and can not obtain fine copper and pure zinc simultaneously, zinc oxide changed into pure zinc need to pass through complicated treating processes, is not very worthwhile on cost.The most frequently used method of extracting copper and zinc from brass is to extract by smelting furnace melting, by high temperature, brass is melted, and the copper that boiling point is high in the time that low-boiling zinc becomes zinc fume, still for liquid, has been realized the separation and Extraction of copper and zinc, the deficiency that the method exists be smelting furnace when in reinforced process, entrained air is melting in its inner air containing oxygen, in the oxidized therefore brass of brass surfaces raw material, also contain micro-oxygen, especially smelting furnace is partly that its oxygen level of open type is larger, oxygen in smelting furnace can react with zinc fume and liquid copper, the cupric oxide in fact and the zinc oxide that finally obtain, and fine copper and cupric oxide, pure zinc and zinc oxide have very large gap in price, waste residue in stove is difficult to melt thoroughly in addition, in the waste residue of therefore discharging, also contain some copper and zinc.In sum, also from brass, can not extract in the market the equipment of fine copper and pure zinc.
Summary of the invention
In order to solve the above-mentioned problem that cannot extract fine copper and pure zinc from brass, the object of the invention is open a kind of novel structure, Energy in use is low, can from brass, extract the brass furnace of fine copper and pure zinc.
In order to realize above-mentioned object, the present invention has adopted following technical scheme:
Brass furnace, comprise airtight body of heater and on feed-pipe and screw rod, the main part of feed-pipe and screw rod is in airtight body of heater, on the external feed-pipe of sealed furnace, opening for feed is set, screw rod is in feed-pipe, the hollow channel of nitrogen that is provided for inflated with nitrogen in screw rod, the inlet mouth of hollow channel of nitrogen is external in sealed furnace, on the non-stress face of the air outlet of hollow channel of nitrogen in screw rod bottom; The top of airtight body of heater arranges the outlet of zinc gas, and the bottom of airtight body of heater arranges the outlet of copper liquid, and sealed furnace body sidewall is provided with pressure regulation porthole, and the below of pressure regulation porthole arranges airtight slag-drip opening, is also provided with the monitor of monitoring stove internal gas pressure on airtight body of heater.
As preferably, also comprise by pressure regulation porthole and insert the reinforced hollow stick of airtight body of heater internal pressure-regulating.The hollow stick reinforced by pressure regulation regulates the air pressure in smelting furnace, remains that the air pressure in smelting furnace prevents entering of air in barotropic state.Pressurize and increased the smelting efficiency of smelting furnace by the reinforced hollow stick inflated with nitrogen of pressure regulation, accelerated the dissolving of waste residue by pressurization, copper wherein, zinc and oxygen are again separated out, inflated with nitrogen has also completely cut off the chemical reaction of oxygen and copper, zinc, the copper that obtains and the purity of zinc are ensured, add coke powder inhaling of oxygen burning again, this operation has further improved the purification efficiency of copper and zinc, has also improved the purification output of copper and zinc.Inflated with nitrogen itself is exactly the chemical reaction for oxygen and copper, zinc, and malleation in smelting furnace can prevent that air from entering.
As preferably, the air outlet of described hollow channel of nitrogen is multiple, and pressure regulation porthole is multiple.
As preferably, described airtight slag-drip opening is hydrocone type slag-drip opening, prevents entering of air.
Adopted the brass furnace of such scheme, adopted airtight body of heater to carry out melting to brass, not only completely cut off a large amount of air and reduced production energy consumption, and it is not contaminated effectively to have controlled near environment brass furnace.Screw rod is in feed-pipe, in screw rod, be provided for the hollow channel of nitrogen of inflated with nitrogen, the inlet mouth of hollow channel of nitrogen is external in sealed furnace, on the non-stress face of the air outlet of hollow channel of nitrogen in screw rod bottom, the effect of hollow channel of nitrogen is that screw rod is lowered the temperature by inflated with nitrogen, prevent the overheated dilatational strain of screw rod, once the overheated dilatational strain of screw rod just cannot play the effect of stirring, especially screw rod is in feed-pipe, on the non-stress face of the air outlet of hollow channel of nitrogen in screw rod bottom, well protect screw rod, once raw material falls into the copper liquid in smelting furnace, a large amount of hot gas comprises that ammonia will be toward rising, the effect that now screw rod bottom ejection nitrogen can well play cooling prevents that hot gas from upwards making screw rod upper deformation, prevent from occurring in feed-pipe the situation of burning simultaneously, this is also that screw rod is arranged on to the reason in feed-pipe, screw rod is exposed just easily distortion in airtight body of heater all, if screw rod is just very easy to damage on the thrust surface of the air outlet of hollow channel of nitrogen in screw rod, above-mentioned design has ensured the work-ing life of screw rod.Hollow channel of nitrogen inflated with nitrogen has also completely cut off the chemical reaction of oxygen and copper, zinc, has ensured the copper that obtains and the purity of zinc, can effectively control solution height and the charging situation etc. in smelting furnace by screw rod, operates very convenient.
In sum, the advantage of this brass furnace is novel structure, and Energy in use is low, has improved the large problem of environmental pollution that traditional extraction equipment and method exist, and can from brass, extract efficiently fine copper and pure zinc.
