Abstract
The fire door mechanism of a kind of novel flexible sealing of the utility model design, comprise body of heater, fire door, fire door panel, it is characterized in that: the lateral surface of body of heater is provided with cylinder holder, cylinder is bolted on cylinder holder, cylinder holder is provided with rotating shaft, the one end swinging rocking arm is hinged in rotating shaft, the axle swung on the other end of rocking arm and fire door is hinged, the head hinge of cylinder is by hinge at about 1/3 place swinging rocking arm, and another axle of fire door is fixed by another axle of fire door angular adjustment bar and cylinder holder.Advantage of the present utility model and positive effect thereof, good sealing effect, fire door close time, fire door perpendicular to fire door panel state deadweight and cylinder double action under compress.Ensure that the effect of sealing, fire door mechanism is simple, and take up room little, the actuating mechanism of fire door is all arranged on the side of body of heater, does not take the operating space in fire door front.Fire door mechanism is simple to operate, and corresponding speed is fast.
Description
Technical field
This patent belongs to machinery industry, is applied to the sealing door of metal melting furnace, is designed into aluminum-alloy melting furnace especially, the sealing door on holding furnace.This fire door adopts cylinder-pressing, and the hermetically-sealed construction that band is flexible.It has good sealing effect, and structure is simple, the features such as action is light, and corresponding speed is fast.
Background technology
Oxidization burning loss is the adverse factor that metal smelting process needs to control always.It is a large amount of slags that metal is formed in oxidizing atmosphere.Oxidization burning loss reduces the earning rate of metal, forms a large amount of flue gases and dust, pollutes air, the environment of exacerbated flushing and casting, and part slag can have the effect of erosion to burner hearth, decrease the working life etc. of burner hearth.Therefore, metal in fusion process will will be in addition strict to the formation of oxidization burning loss control.
By analysis, oxidization burning loss formation main cause is: the existence that in the oven cavity atmosphere of high temperature, oxygen rises.Oxygen comes from combustion system on the one hand, and the surplus of oxygen, than excessive, makes oven cavity atmosphere be oxidisability.At high temperature cause a large amount of oxidization burning loss, on the other hand, when body of heater because fire door etc. is poorly sealed, cause the destroyed of the pressure-fired in burner hearth, air enters burner hearth by fire door etc., forms oxidization burning loss.Traditional burner door sealing structure quick abrasion, hermetically-sealed construction is short for service life, and door structure is huge, complicated operation, and corresponding speed is slow, and the oxidization burning loss improving this type of formation just need improve the hermetically-sealed construction of fire door.
Summary of the invention
The purpose of this utility model solves the unreasonable above-mentioned problem causing oven door sealing sternly existing of oven door sealing structural design in prior art, the fire door mechanism of a kind of novel flexible sealing of the utility model design, comprise body of heater, fire door, fire door panel, it is characterized in that: the below of the lateral surface upper furnace door panel of body of heater is provided with cylinder holder, one cylinder is bolted on cylinder holder, body of heater is provided with upper and lower two rotating shafts, top rotating shaft connects a fire door angular adjustment bar, the other end of fire door angular adjustment bar is connected on fire door by rotating shaft, top rotating shaft connects one and swings rocking arm, the one end swinging rocking arm is connected on fire door by rotating shaft, the top land of cylinder connects the bearing pin that is arranged on the middle part swinging rocking arm.Fire door angular adjustment bar and swing rocking arm are parallel to each other.Advantage of the present utility model and positive effect thereof:
1), good sealing effect, fire door close time, fire door perpendicular to fire door panel state deadweight and cylinder double action under compress.Ensure that the effect of sealing;
2), fire door mechanism is simple, and take up room little, the actuating mechanism of fire door is all arranged on the side of body of heater, does not take the operating space in fire door front.
3), fire door mechanism is simple to operate, and corresponding speed is fast.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model, and accompanying drawing 2,3,4 is fire door working state schematic representation of the present utility model.
Detailed description of the invention
A kind of fire door mechanism of novel flexible sealing, comprise body of heater, fire door, fire door panel, it is characterized in that: the below of the lateral surface upper furnace door panel of body of heater is provided with cylinder holder, one cylinder is bolted on cylinder holder, body of heater is provided with upper and lower two rotating shafts, top rotating shaft connects a fire door angular adjustment bar, the other end of fire door angular adjustment bar is connected on fire door by rotating shaft, top rotating shaft connects one and swings rocking arm, the one end swinging rocking arm is connected on fire door by rotating shaft, the top land of cylinder connects the bearing pin that is arranged on the middle part swinging rocking arm.Fire door angular adjustment bar and swing rocking arm are parallel to each other.
Body of heater 8 side is provided with cylinder holder 1, drives cylinder 2 to be bolted on cylinder holder.Cylinder holder 1 is provided with rotating shaft 4, swings one end of rocking arm 3 and be hinged in rotating shaft 4, the axle swung on the other end of rocking arm 3 and fire door 7 is hinged.The head hinge of cylinder is hinged on about 1/3 place swinging rocking arm 3 by bearing pin 10.Another axle of fire door 7 is fixed by fire door angular adjustment bar 5 another axle with cylinder holder 1, by regulating fire door angular adjustment bar 5 length, just can regulate the angle between fire door 7 and fire door panel 9, ensure that fire door 7 compresses with vertical state, improve air-tightness.Owing to adopting parallel four-bar linkage, can ensure that fire door ensures to compress all the time.
Duty: during unlatching, is driven the thrust of cylinder 2 to be delivered to by bearing pin 10 and swings on rocking arm 3, one end of swing rocking arm 3 is rotated around the axle on cylinder holder 1.Swing the other end of rocking arm 3 to be hinged on fire door and to drive fire door 7 to rotate, the axle on fire door 7 top is hinged by the axle on fire door angular adjustment bar 5 and cylinder holder 1, its ensure furnace door motion be all the time with fire door panel parallel.When driving the formation of cylinder 2 to stop, just complete unlatching.During closedown, action is identical.
Claims (2)
1. the fire door mechanism of a novel flexible sealing, comprise body of heater, fire door, fire door panel, it is characterized in that: the below of the lateral surface upper furnace door panel of body of heater is provided with cylinder holder, one cylinder is bolted on cylinder holder, body of heater is provided with upper and lower two rotating shafts, top rotating shaft connects a fire door angular adjustment bar, the other end of fire door angular adjustment bar is connected on fire door by rotating shaft, top rotating shaft connects one and swings rocking arm, the one end swinging rocking arm is connected on fire door by rotating shaft, the top land of cylinder connects the bearing pin that is arranged on the middle part swinging rocking arm.
