Description
Technical field
The present invention relates to one kind to industrialize zinc metallurgy device, particularly a kind of efficient Zinc powder production device.
Background technology
Electric furnace zinc smelting is using electric energy as thermal source, and under the reducing agent existence condition such as coke or coal, directly heating furnace charge makes it
In ZnO component be continuously reduced into zinc fume and be condensed into metallic zinc.The technique can handle high-copper high ferro zinc ore.
There is electric furnace zinc smelting technology abroad in the 1930s.The eighties, China start to use electric furnace zinc smelting technology, extremely
The present, production scale was more considerable in the popularization and application of Duo Jia pyrometallurgy of zinc factory.
Electric furnace zinc smelting is mainly powered by electric arc furnaces and heated, and raw material in stove is reacted in the presence of electrical heat energy, is obtained
Zinc fume, condensed and operation of gathering dust obtain zinc powder.
Electric arc furnaces（electric arc furnace）It is to utilize high melt ore and metal caused by electrode arc
Electric furnace.Energy is concentrated very much when gas discharge forms electric arc, and arc area temperature is more than 3000 DEG C.For smelting metal, electric arc furnaces ratio
Other converter technological flexibilities are big, can effectively remove impurity, the furnace temperature such as desulfuration, phosphorus and be easily controlled, and occupation area of equipment is small, fit
In the melting of superior alloy steel.
Existing electric arc furnaces conductive bottom has anode assembly, by drainage steel plate, flows steel plate, bottom is drawn steel plate welding and added
Work and furnace bottom refractory brick form with block, but existing direct current zinc metallurgy electric arc furnaces bottom anode electrode structure is easily because of furnace bottom refractory lining
After being corroded by metal bath, cause positive plate to melt, penetrate furnace bottom, cause slag breakthrough accident；Furnace bottom conduction is drawn simultaneously
Steel plate is long and more, need to open multiple furnace bottom rings drawn long mouth to connect extraction copper bar, need design to special procure for this in steel plate of furnace hearth
Shaped steel tendon concrete structure basis, greatly increases electric furnace cost and completion time of project.
Due to the speed of electric furnace zinc smelting production and processing, in electric arc furnaces ore and the speed of reducing agent consumption compared with
It hurry up, then need often to add raw material into electric arc furnaces during zinc metallurgy, but the operation of existing electric zinc stove filling is more troublesome, leads to
Often need to shut down to carry out filling, not only reduce the efficiency of processing, and cost of labor is higher；And in process of production
The speed that heating after raw material is added in electric zinc stove be present is relatively slow, it is necessary to raw material could be warming up to processing temperature by the long period, and
Relatively complicated in the operation that the pre-heat treatment is carried out to raw material at present, device structure is complicated, and input and output material process is cumbersome, and raw material is pre-
Heat is uneven, and pre-heat effect is poor.
In electric furnace zinc smelting process of manufacture, the temperature of zinc fume caused by electric arc furnaces is higher, is difficult in process of production
It is cooled down in time, can be damaged if the zinc fume cooling in tail gas is not just directly discharged into dust arrester installation completely in dust arrester installation
The part in portion, production equipment service life is gently then influenceed, the quality of production is received influences, heavy then cause production equipment to scrap, increasing
Add maintenance cost, delay manufacturing schedule, cause production loss；Current used condenser is mostly spiral coil cooling tube knot
Structure, because spiral coil cooling tube bend pipe loop is more, zinc fume is easily deposited on spiral coil cooling tube bend pipe loop during condensation
In, the velocity of liquid assets of air-flow can be not only influenceed, reduces cooling effectiveness, and easily block cooling tube；If cooling tube is blocked, zinc steams
The heat of vapour institute band can not discharge in time, then easily cause blast, potential safety hazard is larger；To solve the above problems, at present to zinc
Often shut down in powder production process and checked, maintained and changed cooling tube, not only replacement operation is cumbersome, and maintenance cost is higher, and
And production efficiency can be reduced, cause zinc powder overall yield not high.
Because the zinc particle that zinc vapor condensing is formed is smaller, condenser can not collect zinc powder completely, if tail gas is straight
Run in put and not only result in waste, influence zinc powder yield, and the zinc particle in tail gas easily causes and causes environmental pollution to pollute；
Current dust-precipitator zinc powder produce during gather dust it is ineffective, be primarily due to dust easily absorption in dust-precipitator
In gather dust on cloth bag, when adsorbing powder dust to a certain extent after, the cloth bag that gathers dust absorb dust ability can decline to a great extent, cause tail
Zinc powder dust in gas can not be completely absorbed, and waste gas utilization rate is relatively low, can still cause to waste, to solve this problem, at present
Frequently with means be to shut down cleaning to gather dust cloth bag, but the cost safeguarded is higher, and often maintenance shut-downs can shorten dust-precipitator
Service life；So there is the ability shakiness that the cloth bag that gathers dust absorbs dust in existing dust-precipitator during zinc powder produces
Calmly, the problem of dust collection effect is poor, dust-collecting efficiency is relatively low, and the utilization rate of tail gas is relatively low.
When being packed to zinc powder more using sealing bucket；Existing sealing bucket packaging facilities to zinc powder when packing
The problem of dust after zinc powder pouring process is cumbersome, zinc powder is poured into sealing bucket is more loose be present, and capping behaviour can not be carried out
Make, need manually to be sealed lid operation after the completion of filling, it is not only less efficient, be difficult to operate, and the effect sealed
It is unstable, easily influence preservation effect.
Therefore, there is the problem of complicated, process operation is cumbersome in existing zinc powder process equipment, not only mechanization degree
Relatively low, equipment globality is poor, and processing cost is higher, processing efficiency is relatively low, unstable product quality.
The content of the invention
It is an object of the present invention to provide a kind of efficient Zinc powder production device.The zinc powder process equipment of the present invention has machine
The advantages of tool automaticity is higher, globality is relatively strong, zinc powder production and processing efficiency high, in process of manufacture at raw material heat
Speed is managed, treatment effect effect is preferable, and electric zinc stove pan feeding is convenient and swift, heating response speed, and security is higher；It is cold
