Fixed support described in technical solution of the present invention comprises the insulation cover support be arranged on directly over louvre and the side stand be arranged in furnace sidewall, insulation cover support and side stand are equipped with pulley, and magnetic valve lifting starter gear is fixed in the furnace sidewall below side stand.
Louvre diameter described in technical solution of the present invention is 100 ~ 120mm; Stainless steel tube diameter is 50 ~ 80mm; The power of the centrifugal AC air blower of frequency conversion type is 150W, rotating speed is 0 ~ 2800 rev/min.
The present invention is owing to being provided with by the centrifugal AC air blower of frequency conversion type in existing opticglass heat radiation furnace sidewall, stainless steel tube, the air-supply arrangement of blower fan and motor composition, be provided with by insulation cover at opticglass heat radiation stove furnace roof, pulley, fixed support, the top heat abstractor of magnetic valve lifting starter gear and louvre stove composition, thus when the product in annealing furnace does not reach the rate of temperature fall of technique initialization when annealing, regulate by the centrifugal AC air blower rotation speed of fan of computer program regulating and controlling frequency conversion type and send cold blast rate, the insulation cover release furnace heat in the louvre at annealing furnace top is opened by computer program Controlling solenoid valve lifting starter gear, can make the product of annealing in annealing furnace, reach Quick uniform cooling, thus reach the fast cooling speed of technique initialization or the object of annealing cycle shortening, netted belt-conveyor furnace is reached and to ensure in annealing furnace that product is fried or can normal lower disconnected object by process curve cooling.The present invention have make annealing furnace cavity temperature fast, uniform decrease in temperature and the adjustable feature of rate of temperature fall.The present invention is mainly used in the annealing furnace of the opticglass product needing fast cooling annealing process.
Accompanying drawing explanation
Fig. 1 is the fast automatic heat sink structural representation of annealing furnace of the present invention.
In figure: 1, the centrifugal AC air blower of frequency conversion type; 2, stainless steel tube; 3, louvre; 4, magnetic valve lifting starter gear; 5, blower fan; 6, pulley; 7, fixed support; 8, insulation cover; 9, motor.
Embodiment
As shown in Figure 1, the fast automatic heat sink of a kind of annealing furnace of the present invention comprises air-supply arrangement and furnace roof heat abstractor.Air-supply arrangement comprises the centrifugal AC air blower 1 of frequency conversion type, stainless steel tube 2, blower fan 5 and motor 9, blower fan 5 is arranged at furnace chamber one sidewall centre, the centrifugal AC air blower 1 of frequency conversion type and motor 9 are arranged at body of heater outside, motor 9 is connected with blower fan 5, blower fan 5 drives it to rotate by motor 9, stainless steel tube 2 one end is connected with the centrifugal AC air blower 1 of frequency conversion type, and the other end is positioned at immediately below blower fan 5 through behind furnace wall.Stainless steel tube 2 diameter is 50 ~ 80mm; The power of the centrifugal AC air blower 1 of frequency conversion type is 150W, rotating speed is 0 ~ 2800 rev/min.Furnace roof heat abstractor comprises insulation cover 8, pulley 6, fixed support 7, magnetic valve lifting starter gear 4 and is arranged at the louvre 3 of furnace roof above blower fan 5, insulation cover 8 matches with louvre 3, and insulation cover 8 and magnetic valve are elevated in starter gear 4 and are connected by the wireline walking around fixed support 7 top sheave 6 between iron plate valve.Magnetic valve lifting starter gear 4 is currently available productss.Louvre 3 diameter is 100 ~ 120mm.Fixed support 7 comprises the insulation cover support be arranged on directly over louvre 3 and the side stand be arranged in furnace sidewall, and insulation cover support and side stand are equipped with pulley 6, and magnetic valve lifting starter gear 4 is fixed in the furnace sidewall below side stand.
The principle of work of air-supply arrangement is: when the opticglass product in annealing furnace does not reach the rate of temperature fall of technique initialization when annealing, rotating speed by the centrifugal AC air blower 1 of computer program regulating and controlling frequency conversion type regulates and send cold blast rate, its cold wind sent to enters immediately below blower fan 5, in the stove of blower fan 5, thermal cycling is evenly sent in stove after stirring, thus reaches the object made by the rate of temperature fall uniform decrease in temperature of technique initialization in annealing furnace.
The principle of work of furnace roof heat abstractor is: when the opticglass product in annealing furnace does not reach the rate of temperature fall of technique initialization in annealing process, by the conducting of computer program automatic control electric magnet valve lifting starter gear 4, the eddy current magnetism that the current coil be elevated in starter gear 4 by magnetic valve produces holds the iron plate valve on its top, makes it move downward.Iron plate valve is by pulley 6 in its process moved downward, and the insulation cover 8 in 3 li, annealing furnace top heat dissipation hole of slinging, thus release furnace heat, reach the object making fast automatic cooling in annealing furnace.
Such as: when product in annealing furnace is annealed because of the impact by the favorable sealing property of annealing furnace and the heat of the in-built carrier of stove, when not reaching the rate of temperature fall of technique initialization, or technique is when moving to into fast cooling stage (10 DEG C/H ~ 50 DEG C/H) from temperature-fall period at a slow speed, when cannot reach this rate of temperature fall by the naturally cooling cooling method after the heating of annealing furnace stopping stove silk, the insulation cover 8 opening the louvre 3 li at annealing furnace top by computer program control startup magnetic valve lifting starter gear 4 discharges heat energy, rotating speed simultaneously by the centrifugal AC air blower 1 of computer program control adjustable speed frequency conversion type regulates it toward the air output of transporting cold wind in stove, the cold wind sent into is immediately below the blower fan 5 of annealing furnace, send in stove by after the stirring of blower fan 5, warm field in stove is made to reach the cooling rate evenly and rapidly meeting technique initialization.
