Description
Technical field
It the utility model is related to nickel-iron smelting technical field, more particularly to a kind of nickel-iron smelting rotary kiln.
Background technology
Ferronickel is the dilval that nickel content is 20%-60%, and the fusing point of ferronickel is 1430-1480 degree, density 8.1-
8.4.The principal component of ferronickel is nickel and iron, and contains the ferroalloy of a small amount of cobalt.Mineral fracture zigzag, it is uncommon, with block, granular
Aggregate output, in iron is grey, dark-grey or black, streak steel gray, opaque, fresh face metal luster.Also contain in ferronickel
The impurity such as carbon, silicon, sulphur, phosphorus, chromium, copper.It is mainly used as the nickel additive of steel-making and cast iron.Pressed according to international standard (ISO) ferronickel
Nickel content is divided into FeNi20 (15%~25%Ni), FeNi30 (25%~35%Ni), FeNi40 (35%~45%Ni) and FeNi50
(45%~60%Ni).Be further divided into again high-carbon (1.0%~2.5%C), middle carbon (0.030%~1.0%C) and low-carbon (<0.03%C)；It is low
Phosphorus (<0.02%P) with high phosphorus (<0.030%P) ferronickel.When liquid and solid-state, nickel and iron mutual phased soln in any proportion.Silicic acid oxygen
Fire smelting method melting can be used by changing ore deposit, through reducing, melting and refining obtains nickel.To strive for making nickel oxide be changed into metal completely during reduction
Nickel.Ferronickel will separate with lighter slag during fusing.The nickel content of ferronickel depends on the selective power of partial reduction process.Using Jiao
Charcoal makees reducing agent, also can make reducing agent using ferrosilicon.In order to remove carbon impurity, sulphur, phosphorus and the chromium in thick ferronickel, it is necessary to carry out essence
Refining.In electric furnace with carbon direct part reduction refining ferronickel in mineral hot furnace using carbothermy by ore reduction into ferronickel, with
After refined.Frost is in cash 90%.
Ferronickel carries out pyrolytic semlting when smelting, it is necessary to use revolution and store, but existing revolution cellar for storing things is sent by ferronickel ore
Enter to turn round and have that blanking is slow when cellar for storing things is smelted, relatively large ferronickel ore easily blocks feeding-passage, causes blanking to have some setbacks
Freely, the efficiency smelted is influenceed, we design a kind of nickel-iron smelting rotary kiln for this, to solve the above problems.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and a kind of nickel-iron smelting proposed is used
Rotary kiln.
To achieve these goals, the utility model employs following technical scheme：
A kind of nickel-iron smelting rotary kiln, including revolution cellar for storing things main body, one end of revolution cellar for storing things main body are connected with supporting table,

End is stored body rotation with revolution and is connected, the blanking channel that the upside side wall of the supporting table is provided through, the blanking channel
Lower end connect with fixed feeding warehouse, the one end of the blanking channel away from fixation feeding warehouse is connected with crushed aggregates device, described broken
Material device is hollow structure, and inside is provided with two groups of particle rollers, and side of the crushed aggregates device away from blanking channel is connected with
Feed hopper, the lower end of the feed hopper are connected with crushed aggregates device, and helical form blanking oar, the charging are provided with the feed hopper
The upper end of bucket is provided with charging aperture.
Preferably, the crushed aggregates device is provided with opening close to the side of blanking channel, and passes through opening and blanking channel
Connection.
Preferably, the helical form blanking oar and particle roller drive by motor.
Preferably, the junction of the revolution cellar for storing things main body and rotating drum is provided with bearing.
Preferably, it is provided with sliding seal cover on the charging aperture.
Preferably, side of the rotating drum away from revolution cellar for storing things main body is provided with smoke exhaust pipe, and smoke exhaust pipe extends to support
The outside of platform, smoke exhaust pipe are connected with filter.
Compared with prior art, the beneficial effects of the utility model are：In the utility model, helical form blanking oar forces ore deposit
Stone is transported downwards, improves the speed of ore blanking, and after ore enters in crushed aggregates device, finer particle is carried out by particle roller,
By larger ore reduction into more tiny ore, it to be easy to that quickly ore is sent into revolution cellar for storing things, the utility model is novel in design,
While being easy to fast blanking, by ore reduction into more little particle so that ore smelting is more abundant, and ferronickel extraction is higher.
