A kind of superaudio induction melting furnace
Technical field
The present invention relates to a kind of superaudio induction melting furnace.
Background technology
Present industrial traditional smelting furnace generally has following several kinds: coal furnace, oil burner, resistance furnace and intermediate frequency furnace; It exists following shortcoming: (1) coal-fired Shanghai and fuel oil Shanghai all are to adopt the naked light heating; Its flame directly-fired kiln body carries out melting after the temperature that requires, though coal-fired Shanghai and fuel oil Shanghai are simple in structure, investment is big; And exist serious pollution problem, and all there is storage problem in coal-fired, fuel oil; The thermal efficiency is too low in addition, and waste heat recovery is uneconomical again; (2) resistance furnace is that a large amount of resistance wires is wrapped in the body of heater outside; Generate heat to heating furnace body after the temperature that requires, to carry out melting through resistance wire; Resistance furnace is simple in structure, but the thermal efficiency of resistance wire itself is just low, and also has the heat transfer loss through its heating furnace body; And bigger in the process of its heating to extraneous heat output, to heat insulation having relatively high expectations.Resistance wire is a consumable accessory in addition, whenever just must change at a distance from a break time, and its maintenance cost is higher, also need stop production when safeguarding, or use two smelting furnaces to safeguard by turns, and input cost is high; (3) intermediate frequency furnace is that melting is directly carried out to the raw material in the body of heater in the magnetic field that utilizes the Medium frequency induction coil to produce, and is the center heated type, and the intermediate frequency furnace investment is big, power is big, need pass body of heater because of magnetic field raw material is heated, and magnetic loss is big, and the efficiency of heating surface is low.More than all smelting furnaces generally all adopt smelting furnace to add the mode of holding furnace in actual use, every smelting furnace all needs the special messenger to nurse, and also needs the streams swivel link, cost of labor is also than higher.
Summary of the invention
The invention provides a kind of superaudio induction melting furnace, it not only can reduce pollution, and can improve the efficiency of heating surface, reduces cost.
The present invention has adopted following technical scheme: a kind of superaudio induction melting furnace, and it comprises body of heater, body of heater is divided into internal layer and skin; Skin is set to thermal insulation layer; Internal layer is set to combustion chamber, is wound with the superaudio induction coil in the combustion chamber outside, in the gap that the superaudio induction coil is provided with between thermal insulation layer and combustion chamber; Outside the superaudio induction coil, be with insulation material layer, on the superaudio induction coil, be connected with heating control apparatus.
Described combustion chamber is the carborundum graphite crucible.Described insulation material layer is set to porcelain tube.Described body of heater is set to cylinder shape.Described heating control apparatus mainly comprises three phase electric machine, air switch, rectification circuit, filter circuit, inverter circuit and single-chip microcomputer micro-processor interface circuit; Three phase electric machine is connected with the input of single-chip microcomputer micro-processor interface circuit through air switch, rectification circuit, filter circuit, inverter circuit successively; Between the input of inverter circuit and single-chip microcomputer micro-processor interface circuit, be provided with holding circuit and pulse driving circuit; Output at the single-chip microcomputer micro-processor interface circuit is connected with thermorelay, and the single-chip microcomputer micro-processor interface circuit is connected with the superaudio induction coil through thermorelay.Described superaudio induction coil is set to high temperature resistant nickel wire.Described inverter circuit is full-bridge type inverter circuit or half bridge inverter circuit.The port of described single-chip microcomputer micro-processor interface circuit also is connected with LCD, keyboard and temperature protection circuit.Described body of heater is provided with external thermal insulation outward, and external thermal insulation is an alumina silicate.
The present invention has following beneficial effect: the internal layer of body of heater of the present invention is set to combustion chamber; Combustion chamber is the carborundum graphite crucible; Between inside and outside layer, be provided with the superaudio induction coil; The superaudio induction coil is high temperature resistant nickel wire, and it is that the magnetic field that utilizes the superaudio induction coil to produce directly is heated to body of heater and after the temperature that requires, carries out melting.So not only replace traditional high temperature wire, solved the problem that traditional high temperature wire can't be worked under ultra-high temperature with high temperature resistant nickel wire; And adopted the combination of graphite crucible and high temperature resistant nickel wire, avoid the raw material corrosion, and improved service life.After adopting the present invention, it is integrated smelting furnace and holding furnace, need not special messenger's nurse like this, need not the streams swivel link, has saved cost of labor; Invest for a short time, reduced the equipment input cost; Efficient is high, and energy savings has been practiced thrift unit cost; To same melting amount, its power load is little, is the energy consumption contrast table of each stove below:
The energy resource consumption of the various smelting furnaces of table 1 every melting 100kg aluminium
Figure BSA00000663574900021
Electricity price is by 0.7 yuan of calculating, if utilize the electrically heated words of paddy, superaudio induction heater melting per kilogram aluminium only needs 0.1 yuan.
The present invention is connected with heating control apparatus on the superaudio induction coil; It controls the speed of heating through the flow through size of current of nickel wire of heating control apparatus control, and the body of heater volume is changeable, is applicable to the various metals of melting; Limited by temperature; This metal or nonmetallic substance below smelting furnace intelligence melting 1200 degree, according to different use occasions and instructions for use, melting amount, smelting temperature, melting power all can be adjusted; The melting amount can from per hour 50 kilograms accomplish that per hour 500 kilograms are not waited, electrical power can not wait from 20 kilowatts to 200 kilowatts.
