Abstract
The invention relates to a net array type heating method for a glass toughening furnace. Both ends of a roller way are rotatably supported between both sides of the furnace body; heating elements above and below the roller way are used to heat processed glass loaded on the roller way; a blast pipe parallel to the roller way is arranged between the upper and/or the lower of the roller way and the heating elements, and the heating elements and the blast pipe are crossed in a net shape; and a high temperature fan compresses hot air to the blast pipe. The invention is characterized in that the refractory steel blast pipe is parallel to the transmitting roller way, and the refractory steel blast pipe and heating wires are perpendicularly arranged to form a net array. The furnace wires carry out radiation heating on the glass and the refractory steel blast pipe adjacent to the furnace wires simultaneously, the fan blows the air heated in the furnace into the refractory steel pipe, the hot air is heated continuously when flowing in the steel pipe and is then blown to the surface of the glass to heat the glass, and the glass plate heating speed is greatly raised under the double effects of radiation heating and convection heating, thereby the processed glass has higher quality.
Description
Technical field
The present invention relates to the glass heats stove of a kind of novel texture and type of heating, specifically is a kind of net configuration heated glass annealing furnace.
Background technology
In traditional glass heats stove, each heating unit evenly is arranged near the upper and lower surface of glass, and heat mainly is delivered to the heating of the surface realization of glass to glass by the radiating mode.Radiation heating is the slowest a kind of mode of conducting heat in conduction, convection current, three kinds of type of heating of radiation, under equal temp of heating element, making glass reach same temperature needs long heat-up time, and heat-up time, length can make the optical quality of glass sustain damage.When being heated glass and being coated glass, owing to there is the one side of rete to have lower radiant ratio, heat is difficult to pass rete to glass heats by the radiating mode, and it is longer that glass reaches the required time of requirement temperature; And the one side that does not have rete so just causes the ununiformity of heat absorption down on glass still with the heat absorption of heat absorption speed faster usually, and the optical quality of the glass after the processing is poorer.
Summary of the invention
The invention discloses a kind of net configuration heated glass annealing furnace, the rate of heating that prior art exists is slow to solve, the optical quality of the glass after the processing is poor, and the problem of face one side of coated glass heating difficulty.
Technical scheme of the present invention is: the two ends of rotational support roller-way between the body of heater both sides, adopt heating unit that the processed glass that is carried on the roller-way is heated in the above and below of this roller-way, it is characterized in that: above the described roller-way and/or below with heating unit between the blowpipe parallel with described roller-way is housed, a side of facing roller-way at this blowpipe is provided with ventilation hole, and make this heating unit and blowpipe be netted to intersect, be pressed into hot blast by high-temperature blower in this blowpipe, the convection current hot blast that radiant heat that heating unit produces and blowpipe eject is jointly to the surperficial even heating of glass.
Described heating unit is made of the nichrome wire that is wrapped on the parent tube.
The adjacent side profile spacing of described heating unit and blowpipe is less than 70mm.
Several described heating units interconnect the composition heating region, at each this heating region temperature regulating device are housed.
The ventilation hole of described blowpipe is evenly arranged, and adjacent ventilation hole is interlaced.
Described high-temperature blower is configured in both sides or the top and the bottom of furnace body inside.
The characteristics that the present invention is conducted heat and not influenced by rete according to convective heating are introduced high-temperature blower and blowpipe in process furnace, the blowpipe of heat-resisting steel is parallel with glass conveying roller way, the perpendicular composition net of the heater strip on airduct top battle array.The stove silk carries out radiation heating to glass and high temperature steel airduct, blower fan blasts the air through heating in the stove in the heat resisting pipe, warm air continues to be heated when flowing in steel pipe, then blow to glass surface to glass heats, sheet glass just is under the effect of radiation and two kinds of type of heating of convection current simultaneously like this, has improved rate of heating greatly, simultaneously, the temperature of each heating region all is controllable, makes that heating is more even, and the glass after the processing has higher quality.

Embodiment
Referring to Fig. 1 and Fig. 2, the two ends of the present invention's rotational support roller-way 6 between body of heater 1 both sides, the processed glass 5 that adopts 3 pairs of heating units to be carried on the roller-way 6 in the above and below of this roller-way 6 heats.The blowpipe 4 of heat-resisting steel is housed between described roller-way 6 and heating unit 3, and blowpipe 4 is parallel with described roller-way 6, is provided with ventilation hole at this blowpipe 4 in the face of a side of roller-way 6; The two ends of this blowpipe 4 are connected with the sidepiece airduct 7 that is located at inside, body of heater 1 both sides respectively, and this sidepiece airduct 7 is connected with the air outlet that is located at the intravital high-temperature blower 2 of stove.Described heating unit 3 is made of the nichrome wire that is wrapped on the parent tube (as porcelain tube).Axially axially mutual vertical with blowpipe 4 of heating unit 3, the profile distance＜70mm of an adjacent between the two side.Like this, heating unit 3 has just been formed net battle array heating arrangement as shown in Figure 2 with blowpipe 4, be pressed into hot blast by high-temperature blower 2 in this blowpipe 4, the convection current hot blast that radiant heat that heating unit 3 produces and blowpipe 4 eject is jointly to the surperficial even heating of glass 5.
Several described heating units 3 interconnect (serial or parallel connection) and form a heating region, and the thermopair (not shown) of control Heating temperature is installed at each this heating region.
The ventilation hole of described blowpipe 4 is evenly arranged, adjacent ventilation hole interlaced (not shown).
High-temperature blower 2 is installed in the both sides of body of heater 1, also can be installed in top and bottom.The air suction inlet of high-temperature blower 2 is towards furnace chamber inside, and the air outlet of high-temperature blower 2 links to each other with sidepiece airduct 7.
As required, blowpipe 4 can all be installed in the body of heater top and the bottom form the whole network battle array stove (as shown in Figure 1), also can blowpipe 4 only be installed on the top of body of heater 1 and form half net battle array stove.
Specific embodiment of the invention process is, under the driving of high-temperature blower 2, air is at high-temperature blower 2 inlets, high-temperature blower 2 outlets, sidepiece airduct 7, blowpipe 4, the heating unit 3 (shown in arrow among Fig. 1) of flowing through successively in the stove, in stove, form circulating current, heating unit 3 energising rear surface temperature fast rise, air is heated before entering high-temperature blower 2 through its nichrome wire, is then crossed sidepiece airduct 7 by preliminarily heated air communication and enters in the blowpipe 4.Because the high temperature steel thermal conductivity is big, the blowpipe 4 of heat-resisting steel can heat up rapidly under the situation of close proximity with nichrome wire in the raying effect, air-flow can continue again to be heated when flowing in airduct, then blow to glass 5, simultaneously, heating unit 3 can carry out radiation heating to glass 5 through the space between the blowpipe 4.Set the Heating temperature in each stove silk zone by thermopair, just can realize controlling temperature with region, glass can be raised to design temperature quickly and evenly under the effect of two kinds of type of heating.
