The utility model is characterized in that one end of the inducing body is provided with an enclosed wind cooling box, the side wall of the wind cooling box is provided with at least one cooling blower fan, to extract the air in the box to form negative pressure, and thereby attracting the cold air to enter from an air inlet opening at the other end of the box. The quantity of the cooling blower fan is preferably two which are respectively arranged on the two opposite sides of the outer wall of the wind cooling box. The utility model changes a traditional air blowing type cooling into the air extracting type negative pressure cooling, thus obviously strengthening the cooling effect of the inducing body, and enhancing the service life of the furnace lining of the inducing body. Thereby the utility model is allowed to be produced to be a zinc melting induction furnace with higher power. Simultaneously, the construction cost of the equipment can be reduced, and the construction cost of each electric furnace is reduced by 5 to 150000 Yuan. The power consumption and the noise of the zinc melting induction furnace can also be reduced.
Description
Technical field
The utility model relates to line frequency furnace, particularly a kind of high-power air-cooled electric induction furnace that is used for molten zinc.
Background technology
Zinc-melting furnace is used to melt electrolysis cathode zinc metal sheet and kirsite etc.Operating temperature is 450～550 ℃.Iron core, the induction coil of general molten zinc of electric furnace inductor is to adopt air-cooled or water-cooling pattern.The ubiquity investment is big, takes up an area of big shortcoming.Water cooling inductor equipment is higher to water quality requirement, and the user is on-the-spot to need to be equipped with the complicated water treatment facilities of a cover, and needs to safeguard throughout the year, expends a large amount of human and material resources.Molten zinc of electric furnace air cooling way normally is installed in blower fan inductor and carries out the bleed type cooling outward.Coil and the furnace lining lining of high pressure cold wind in airduct blows to inductor.This air blast type of cooling exists that airduct is long, the airduct resistance is big, the shortcoming of cooling effect difference.Not only the blower fan consumed power is big, noise is big, and the inductor temperature drift, influences inductor furnace lining service life.Lining durability only has 3～6 months usually.Because above-mentioned traditional type of cooling weak effect has limited the raising of molten zinc inductor power greatly.Existing molten zinc of electric furnace has only a typhoon machine, no standby fan usually.In case break down, lose cooling, inductor is easy to burn out because of overheated.
Summary of the invention
The purpose of this utility model is to avoid the above-mentioned deficiency of prior art, and what a kind of good cooling results was provided is suitable for the air-cooled electric induction furnace of powerful molten zinc.By strengthening air cooling effect, the power and the service life of improving inductor.
The air-cooled electric induction furnace of the high-power molten zinc of the utility model, comprise the heating inductor of forming by iron core, induction coil, furnace lining lining and furnace lining, it is characterized in that: be provided with airtight air-cooled case at heating inductor one end, the sidewall of this air-cooled case is provided with at least 1 cooling blower that air extraction in the case is made it to form negative pressure.
Above-mentioned cooling blower preferably is contained on the outer wall of air-cooled case.
Above-mentioned cooling blower can be 2, is contained in the relative both sides of air-cooled case respectively.
On above-mentioned air-cooled case, can be provided for clearing up the detachable deep bead of dust.
Description of drawings
Fig. 1 is the stereochemical structure decomposing schematic representation of the molten air-cooled electric induction furnace of zinc.
Fig. 2 is the overall structure schematic diagram after Fig. 1 installs.
The specific embodiment
Referring to accompanying drawing, iron core 11, induction coil 12, furnace lining lining 13 and furnace lining 16 constitute the heat-generating units 1 of inductors.Their trouble free service is extremely important to the life-span of inductor.Iron core among the figure, induction coil, furnace lining lining and furnace lining etc. are formed two cover heaters, and they are symmetrical structures.The utility model is provided with air-cooled case 10 at an end of iron core 11, induction coil 12 and the furnace lining lining 13 of general inductor assembly, keeps sealing around the air-cooled case.The both sides of air-cooled case 10 respectively are provided with a cooling blower 3.The air inlet of blower fan 3 is contained on the circular hole 8 of air-cooled case 10, and fan outlet 4 is located at outside the air-cooled case 10.Blower fan 3 and motor 17 etc. are loaded on the air-cooled case outside by fixture 6, bolt 7 etc.Blower motor 17 is supported by carriage 5.The maximum characteristics of this inductor cooling are to adopt the mode of bleeding to cool off.During work, blower fan 3 is bled in case, and exhaust outside case forms negative pressure in the air-cooled case 10 of sealing, attract cold wind to enter inductor from the air inlet 15 of the other end.Gap between iron core 11 and induction coil 12 and the air channel 14 between induction coil 12 and the furnace lining lining 13 enter air-cooled case 10, and iron core 11, induction coil 12 and furnace lining lining 13 each several parts are effectively cooled off.Hot blast enters air-cooled case 10 backs and enters ambient atmosphere by blower fan 3.Above-mentioned negative pressure air draught type cooling is because the cold wind flow resistance is little, and flow velocity is fast, and air quantity is big, and its effect obviously is better than blowing or blowing-type cooling.
Two cover induction coil 12 and the furnace lining linings 13 that symmetry is twined on the inductor iron core 11, its cold air duct all communicates with air-cooled case 10.Cold wind becomes hot blast after the inductor cooling, enter air-cooled case 10.Blower fan 3 is in time extracted hot blast to keep the negative pressure in the air-cooled case out, constantly attracts new cold wind to enter from air inlet 15.This structure can overlap induction coils 12 to two of inductor simultaneously and furnace lining lining 13 cools off.One typhoon machine 3 respectively is installed on the biside plate 9 of figure apoplexy ice chest 10, even wherein a typhoon machine breaks down, this structure still has certain cooling effect to whole inductor.The inductor cpable of lowering power continues to use, thereby guarantees the continuity of production.The reason cooling does not stop to make inductor that cause thermal damage took place.
The deep bead 2 of air-cooled case 10 is dismountable.Deep bead can be pressed on the air-cooled case 10 by bolt and sealing gasket.Inductor between iron core 11 and induction coil 12, is saved bit by bit dust between induction coil 12 and furnace lining lining 13 and in the air-cooled case 10 after operation after a while.The cleaning of these dusts can be undertaken by dismounting deep bead 2.Deep bead is set guarantees to demonstrate,prove the unimpeded of above-mentioned each ventilation gap and air channel, help the cooling of inductor and the service life of improving the inductor furnace lining.
The utility model compared with prior art has following advantage:
1, changes the blowing-type cooling cooling of into exhausting formula negative pressure, obviously strengthened the cooling effect of inductor.Thereby allow to make more powerful molten zinc induction furnace.
2, improved the service life of inductor furnace lining greatly, can reach more than 2 years under the normal condition.Have only 3～6 months the service life of furnace lining in the past.
3, equipment manufacturing cost is low, and every electric furnace cost can reduce by 5～150,000 yuan.Simple to operate, working service is convenient.
4, can reduce the power consumption of molten zinc of electric furnace, thereby reduce operating cost, and can reduce noise.
5, simple in structure, reasonable in design.
