Abstract
The invention relates to a furnace lid device of a small electric induction furnace. A furnace body of the electric induction furnace is installed on a support seat through a trunnion; a furnace platform board is arranged above the furnace body of the electric induction furnace; connection boards are fixedly connected with two sides of the front side of the furnace platform board respectively, bearing seats are fixedly installed on the two connection boards; bearings are installed in the two bearing seats; hollow main shafts are installed in the two bearings; swinging cylinders are installed on outer sides of the two bearing seats through connection disks; extending shafts of cylinder shafts of the two swinging cylinders are installed in hollow main shaft holes of the hollow main shafts; extending shaft key grooves are arranged on the extending shafts; flat keys are embedded between the hollow main shafts and the extending shaft key grooves in a tightly matched mode; dust covers are installed on inner sides of the two bearing seats, and flanges at outer ends of the two hollow main shafts are connected with two framework bases respectively; and a furnace lid is installed on lower portions of ends of two framework sides, the ends of the two framework sides and the framework bases are welded, and the swinging cylinders are connected with a control console through guide pipes. By means of the furnace lid device of the small electric induction furnace, the quantity of heat energy diffused to the air and loss of electric energy can be substantially reduced, production costs of molten iron can be greatly reduced, and the furnace lid device has advantages of being simple in structure, light, small in occupied space and convenient to operate.
Description
Technical field
The present invention relates to the furnace cover device of the small-sized electric induction furnace that a kind of casting industry fusing molten iron uses.
Background technology
The electric induction furnace that casting industry fusing molten iron uses, its power consumption some heat except smelting iron water consumption causes toward dissipating in air.Along with improving constantly of molten iron temperature, also more to the heat distributing in air.Likely in the link of the heat distributing in air, the heat distributing take fire door, as at most, can reach the more than 70% of distribute heat total amount.Therefore, general electric furnace is all furnished with the heat that furnace cover device distributes to reduce fire door.Although many electric induction furnaces are all furnished with bell in the time that electric induction furnace dispatches from the factory, because bell is heavier and inconvenient operation, most bells are abandoned and need not.There is furnace cover device from the electric induction furnace great majority of external import and introduction are all supporting, and generally all adopt the Push And Release of hydraulic means control bell.But the table of 0.5T/h fusing amount and following small-sized electric induction furnace is less and bell mobile space is little, so be generally all unworthy of shove charge lid arrangement.
At present, domestic each Foundry Works is also generally used 0.5T/h fusing amount and following small-sized electric induction furnace.The small-sized electric induction furnace of this class is annual also quite a lot of toward the heat distributing in air, national each small-sized electric induction furnace whole year because of the loss of the electric energy that the heat distributing in air causes be quite surprising.
Summary of the invention
The object of this invention is to provide a kind of furnace cover device of small-sized electric induction furnace.This furnace cover device can reduce greatly toward the quantity of distributing heat energy in air, can reduce the loss of electric energy relatively largely, can reduce significantly the production cost of fusing molten iron.That this furnace cover device also has advantages of is simple in structure, lightweight, it is little and easy to operate to take up room.
Technical scheme of the present invention is: a kind of furnace cover device of small-sized electric induction furnace.Induction furnace body is arranged on carrier base by gudgeon.Above induction furnace body, be provided with furnace platform.Be characterized in: at the each affixed connecting plate in the both sides, front of furnace platform.On two connecting plates, be all installed with bearing block.Bearing is all installed in diaxon bearing.Hollow main shaft is all installed in two bearings.Outside in diaxon bearing is all provided with oscillating cylinder by terminal pad.The projecting shaft of two oscillating cylinder cylinder axles is installed in the hollow main shaft hole of hollow main shaft.On projecting shaft, have projecting shaft keyway.Flat key tight fit is inlaid between hollow main shaft and projecting shaft keyway.The inner side of diaxon bearing is all provided with dust cap, and the outer end of two hollow main shafts is flange, and two flanges are connected with two frame bases respectively.One end, framework both sides are each welds with frame base.Bell is equipped with in the bottom of framework, and the stockhole of this bell and electric induction furnace and the notch that taps a blast furnace are equipped with.Oscillating cylinder is connected with console by conduit.
The course of work of the present invention is: in the time that needs are opened bell, open the reversing air valve of console to oscillating cylinder air feed, oscillating cylinder swings after bringing about the desired sensation and drives projecting shaft to rotate, when rotating, projecting shaft by flat key, hollow main shaft is rotated, hollow main shaft drives frame base to rotate by flange, frame base drives framework while rotation and is contained in the bell rotation of framework bottom, bell upwards rotates 90 from flat state and spends into plumbness, close reversing air valve and stop to oscillating cylinder air feed, now bell is in open mode.In the time that needs cover bell, open the reversing air valve of console to oscillating cylinder air feed, oscillating cylinder swings after bringing about the desired sensation and drives projecting shaft to rotate backward, when rotating backward, projecting shaft by flat key, hollow main shaft is rotated backward, hollow main shaft drives frame base to rotate backward by flange, the bell that drives framework when frame base rotates backward and be contained in framework bottom rotates backward, bell rotates 90 from plumbness and spends into flat state, close reversing air valve and stop to oscillating cylinder air feed, now bell is in covering the state on stockhole.
Advantage of the present invention has been to provide a kind of furnace cover device of small-sized electric induction furnace.This furnace cover device can reduce greatly toward the quantity of distributing heat energy in air, can reduce the loss of electric energy relatively largely, can reduce significantly the production cost of fusing molten iron.That this furnace cover device also has advantages of is simple in structure, lightweight, it is little and easy to operate to take up room.
