Description
Technical field
The present invention relates to a kind of brass furnace.
Background technology
Brass is important metallic substance, is used widely.Can produce a large amount of brass scrap raw materials in the process of production and use brass ware, 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 extract copper and zinc from brass, sell separately or recycling.
The method of mostly extracting at present copper and zinc from brass is mainly two kinds, a kind ofly be disclosed as " CN1113520 " as Chinese patent, name is called " reclaiming copper and Zinc hydrometallurgy method 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 gets zinc subcarbonate through ammonia still process, send and calcines to get active zinc flower." deficiency that exists of the method is to obtain metallic copper and zinc oxide, and can not obtain simultaneously fine copper and pure zinc, zinc oxide is changed into pure zinc need to be 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 the smelting furnace melting, by high temperature, brass is melted, and the copper that boiling point is high when low-boiling zinc becomes zinc fume has been realized the separation and Extraction of copper and zinc still for liquid, the deficiency that the method exists is that smelting furnace contains oxygen in its inner air when entrained air is melting in reinforced process, also contain the oxygen of trace in the oxidized so brass raw material of brass surfaces, especially partly smelting furnace is 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 on price, waste residue in stove is difficult to melt thoroughly in addition, the copper and the zinc that also contain some in the waste residue of therefore discharging.In sum, also can not extract in the market the equipment of fine copper and pure zinc from brass.
Summary of the invention
Above-mentionedly can't to extract the problem of fine copper and pure zinc from brass in order solving, to the objective of the invention is to disclose a kind of novel structure, Energy in use is low, can extract the brass furnace of fine copper and pure zinc from brass.
In order to realize above-mentioned purpose, 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, be provided for rushing the hollow channel of nitrogen of nitrogen in screw rod, it is external that the inlet mouth of hollow channel of nitrogen is in sealed furnace, and the air outlet of hollow channel of nitrogen is on the non-stress face of 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 the sealed furnace body sidewall is provided with the pressure regulation porthole, and the below of pressure regulation porthole arranges airtight slag-drip opening, also is provided with the monitor of monitoring stove internal gas pressure on airtight body of heater.
As preferably, also comprise by the pressure regulation porthole and insert the reinforced hollow stick of airtight body of heater internal pressure-regulating.The hollow stick of feeding in raw material by pressure regulation is regulated the air pressure in smelting furnace, remains that air pressure in smelting furnace is in barotropic state and prevents entering of air.The hollow stick of feeding in raw material by pressure regulation is rushed nitrogen and is pressurizeed and increased the smelting efficiency of smelting furnace, accelerated the dissolving of waste residue by pressurization, copper wherein, zinc and oxygen have again been separated out, rush the chemical reaction that nitrogen has also completely cut off oxygen and copper, zinc, the copper that obtains and the purity of zinc have been guaranteed, add coke powder inhaling of oxygen burning again, namely this operation has further improved the purification efficiency of copper and zinc, has also improved the purification output of copper and zinc.Rush nitrogen itself and be exactly the chemical reaction for oxygen and copper, zinc, and the malleation in smelting furnace can prevent that air from entering.
As preferably, the air outlet of described hollow channel of nitrogen is a plurality of, and the pressure regulation porthole is a plurality of.
As preferably, described airtight slag-drip opening is the 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 near the environment of effectively having controlled brass furnace is not contaminated.screw rod is in feed-pipe, be provided for rushing the hollow channel of nitrogen of nitrogen in screw rod, it is external that the inlet mouth of hollow channel of nitrogen is in sealed furnace, the air outlet of hollow channel of nitrogen is on the non-stress face of screw rod bottom, the effect of hollow channel of nitrogen is that screw rod is lowered the temperature by rushing nitrogen, prevent the overheated dilatational strain of screw rod, in case the overheated dilatational strain of screw rod just can't play the effect of stirring, especially screw rod is in feed-pipe, the air outlet of hollow channel of nitrogen is on the non-stress face of screw rod bottom has well protected screw rod, in a single day 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 ejection nitrogen in screw rod this moment bottom can well play cooling prevents that hot gas from upwards making the screw rod upper deformation, prevent from simultaneously occuring in feed-pipe the situation of burning, this is also that screw rod is arranged on reason in feed-pipe, screw rod is exposed just easily distortion in airtight body of heater all, on the thrust surface of screw rod, screw rod just is very easy to damage if the air outlet of hollow channel of nitrogen is in, and above-mentioned design has guaranteed the work-ing life of screw rod.The hollow channel of nitrogen rushes the chemical reaction that nitrogen has also completely cut off oxygen and copper, zinc, has guaranteed the copper that obtains and the purity of zinc, can effectively control solution height in smelting furnace and charging situation etc. 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 extract efficiently fine copper and pure zinc from brass.
