Description
Technical field
The utility model relates to the technical field of ore beneficiation equipment, particularly relates to the preparation equipment of refractory gold ore and iron ore, for opening gold parcel, improving the rate of recovery, relating to Electromagnetic Heating reactor rotary kiln voltage changer concretely.
Background technology
Rotary kiln is mainly used in mine, can carry out initial processing to breeze, improves mineral precision, especially gold mine or iron ore, for iron ore,
iron orespecifically have a variety of, main two kinds are exactly
magnetic iron ore(Fe3O4) and
bloodstone(Fe2O3), the latter is commonly called as again as red ore deposit.China
iron orebe generally lean ore, grade, about 30, generally all needs to carry out
ore dressing.Low-grade
rhombohedral iron ore beneficiation technicscomplexity, not easily realizes.Therefore, China
ore dressingwhat major part was selected is
magnetic iron ore, be physics
ore dressing, technically easily realize.In order to increase beneficiating efficiency, in screening
magnetic iron ore, ore is processed before, the impurity iron element high temperature oxygen in ore is changed into Fe3O4, and then ore dressing, the rate of recovery of ferro element can be improved.Be exactly reactor to the device of impurity iron element high-temperature oxydation.Reactor has the following advantages: 1, heating is fast, and 2, heating-up temperature is accurate, temperature can reach 1300 DEG C, and 3, environmental protection noiselessness.Reactor can physical reactions also can chemical reaction, be particularly useful for the ore treatment in mine, there is the function such as desulphurization and denitration, dearsenification, because its heating-up temperature is high, metallurgy, pharmacy, oven dry tealeaves etc. can also be used for, of many uses.Will heat impurity iron element, need high temperature to heat mineral aggregate, the power required due to Electromagnetic Heating reactor rotary kiln is very high, and the mode of heating how designing Electromagnetic Heating reactor rotary kiln is a very important thing.
Utility model content
Technical problem to be solved in the utility model is for the above-mentioned state of the art, and the Electromagnetic Heating reactor rotary kiln voltage changer providing a kind of use safety, efficiency high.
The utility model solves the problems of the technologies described above adopted technical scheme:
Electromagnetic Heating reactor rotary kiln voltage changer, comprise kiln body, barrel through before and after being provided with in kiln body, wherein: reactor rotary kiln is also provided with transformation system, transformation system includes the transformer be connected with extraneous AC power, voltage reduces by transformer, transformer connects rectifier, rectifier by whole for alternating current be direct current, after rectifier connects DC booster, be connected in kiln body, inverter is provided with in kiln body, rectifier is connected with inverter, inverter is connected with electromagnetic heating coil, the outside that electromagnetic heating coil is wrapped in barrel is barrel heating.
For optimizing technique scheme, the concrete measure taked also comprises:
Above-mentioned DC booster adopts DC-DC boost chopper.
Above-mentioned barrel is the irony cylindrical shell that inner side is coated with corrosion-resistant coating.
Above-mentioned transformer is arranged separately in area of isolation.
