Description
Technical field
The utility model relates to the smelting furnace of metallurgy industry, particularly relates to the improvement to smelting furnace structure.
Background technology
Induction heater is a kind of supply unit power frequency 50HZ alternating current being changed into intermediate frequency (more than 300HZ is to 1000HZ), three-phase main-frequency alternating current, direct current is become after rectification, again direct current is become adjustable electric current of intermediate frequency, supply is by the intermediate frequency alternating current flow through in electric capacity and induction coil, in induction coil, produce the highdensity magnetic line of force, and cut the metal material held in induction coil, in metal material, produce very large eddy current.This eddy current has the properties of electric current of intermediate frequency equally, that is, the free electron of metal self flows and will produce heat in the metallic object having resistance.Smelting non-ferrous metal the most at last in stove is liquid (aluminium, zinc, lead, copper etc.).
The induction heater (intermediate frequency furnace) of current extensive use adopts copper pipe as " wire " of coil mostly.As the CN202074818U that State Intellectual Property Office 2011.12.14. announces, namely the patent document of title " a kind of mid-frequency melting furnace ", wherein adopt copper tube to be coiled in body of heater, in view of the wall of copper tube is thinner, when in body of heater, temperature raises, easy melting, also needs water flowing cooling in pipe.The maximum problem of this technical scheme is: protecting copper tube while, " taken away " by the amount of heat in body of heater, is reduction of the overall efficiency of heating surface actually.
The CN201909529U that State Intellectual Property Office 2011.7.27. announces, the patent document of title " energy-efficient smelting furnace ", also relates to the technical measures of " cooling water tank " in its technical scheme.
In addition, the crucible in induction heater (intermediate frequency furnace), cost is higher, is often higher than the cost of wherein one pot of material.And crucible in use, when can break, cannot effectively predict.Often can be once multiplex, a benefit can be produced for the producer.And break after generally in use reaching uniform temperature and occur, in other words, in use, it is inevitable for occurring that crucible breaks, although liquid metal wherein can be recycled after solidification.But when breaking, liquid metal can flow on the wire of induction coil, gently then bond wire, heavy then cause short circuit, causes electric fault, form great loss.
Summary of the invention
The utility model, for above-mentioned technical problem, provides one when crucible breaks, induction coil can be avoided to damage, and the high performance induction energy-saving smelting furnace that thermal efficiency is higher.
The technical scheme in the invention for solving the technical problem is: a kind of high performance induction energy-saving smelting furnace, comprise shell, fire-resistant furnace shell in the enclosure, coil induction coil in fire-resistant furnace shell inwall and the crucible that is positioned in the middle of induction coil, the wire of described induction coil is arranged with some bowl-shape ceramics.
Concrete further, described wire is solid construction, and its diameter is 3 ~ 8mm.
Concrete further, be provided with outlet bottom described fire-resistant furnace shell.
Concrete further, described bowl-shape ceramics is taper tubular; The internal diameter of described bowl-shape ceramics osculum end is greater than the external diameter of described wire, and the internal diameter of big opening end can make the osculum end of another bowl-shape ceramics described embed the height of 1/4 ~ 1/2.
Concrete further, the both sides outer contour of the axial cross section of described bowl-shape ceramics is the curve of evagination.
Concrete further, be filled with insulation filler between described shell and fire-resistant furnace shell.
The beneficial effects of the utility model are: after have employed said structure, because the sintering temperature of ceramic material is generally more than 1100 DEG C, and there is excellent isolation and insulating properties, even if occur that crucible breaks, liquid metal flows out, also can because of the buffer action of bowl-shape ceramics and insulating effect, avoid boning, the phenomenon of short circuit.The wire of induction coil adopts solid construction (fusing point is not less than 1100 DEG C), even if the temperature acting in opposition in body of heater, conductor temperature is raised, also wire can be avoided to fuse, the most key: the temperature in furnace shell is lowered the temperature without the need to adopting cooling device, heat energy in furnace shell is effectively utilized, and thermal efficiency gets a promotion.The utility model increases greatly relative to prior art service life, thermal efficiency is improved, and has saved a large amount of electric power energies.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is explained in detail.
The present invention, as shown in Fig. 1 ~ 5, comprises shell 1, fire-resistant furnace shell 3 in shell 1, coils induction coil in fire-resistant furnace shell 3 inwall and the crucible 4 that is positioned in the middle of induction coil, be provided with insulation filler 2 between shell 1 and fire-resistant furnace shell 3; Described induction coil in the shape of a spiral winding, on the inwall of described fire-resistant furnace shell 3, is arranged with some bowl-shape ceramics 9 outside the wire 6 of described induction coil.When the inwall of fire-resistant furnace shell 3 arranges induction coil, generally have two kinds of means, one is adopt as Fig. 1,2,3 groove 8 at any time, and in order to prevent wire 6 from departing from groove 8, arranges flange 81 at the end opening of groove 8; Two is adopt to arrange the form of supporting lug 10 (as shown in Figure 6 on the inwall of fire-resistant furnace shell 3, it can be continuous helical chimb form, also can be according to the spaced projection form of helical trajectory), making wire winding in the shape of a spiral, take the second as optimization means.
The wire 6 of described coiling induction coil is solid construction, and diameter is 3 ~ 8mm.This makes overall thermal efficiency be improved, and without the need to adopting cooling device, is discharged by the heat energy in body of heater.For extending the life-span of induction coil further, the material selecting fusing point to be not less than 1100 DEG C is good.
Outlet 7 is provided with bottom described fire-resistant furnace shell 3.In view of breaking of aforementioned crucible 4 cannot be avoided, before breaking, material 5 is generally in a liquid state; After breaking, liquid material discharges out of the furnace by the outlet 7 of bottom.
Described bowl-shape ceramics 9 is taper tubular, and the internal diameter of osculum end 91 is greater than the external diameter of described wire 6; The internal diameter of big opening end 92 can make the osculum end of another bowl-shape ceramics 9 described embed the height of 1/4 ~ 1/2.Mutually can be socketed like this, wire 6 is effectively protected, realize isolation, insulation effect.The interior shape of big opening end 92 and the outer shape of osculum end 91 mutually adaptive, form face contact time, isolation effect is better.
The both sides outer contour of the axial cross section of described bowl-shape ceramics 9 is the curve of evagination.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
