Abstract
The utility model discloses a kind of glass heating furnace, it is included in the plenum chamber that the both sides up and down of glass conveying roller way or side are arranged and the jet plate being arranged on plenum chamber exit; The cross section of jet plate is wavy, and high-temperature gas outlet is arranged on the crest place of jet plate; The spacing of Wave crest and wave trough is consistent with the spacing of glass conveying roller way in stove, and crest correspondence is arranged in the middle of two adjacent roller-ways, and trough then just corresponds to roller-way.Structure of the present utility model makes the central idle place blowing hot-air of corresponding two roller-ways of blowing mouth, thus relatively compensate for the rate of heating of this place's glass, thus glass is heated evenly everywhere, contributes to the quality of finished promoting glass.
Description
Technical field
The utility model relates to a kind of glass heating furnace.
Background technology
In prior art, glass heating furnace is the key equipment of glass tempering unit, and it is according to the difference of type of heating, is roughly divided into full convection oven, semi-convective process furnace (convective heating and radiation heating combine) and radiant-type furnace.Be illustrated in figure 1 the structural representation of full convection oven, comprise: the furnace chamber be made up of upper furnace body 2 and lower furnace body 1, this furnace chamber is provided with into fire door 3 and plug for outlet 4, also comprise sheet glass e Foerderanlage 5, for sheet glass is transferred to plug for outlet 4 from entering fire door 3, glass-panel conveying path is from entering the passage of fire door to plug for outlet, convection current case is provided with in the both sides up and down of sheet glass rollgang 5, convection current case comprises plenum chamber 6 and is arranged on the jet plate 7 in plenum chamber 6 exit, gas in plenum chamber 6 is ejected on the surface of the sheet glass 100 be positioned on sheet glass e Foerderanlage 5 by the high-temperature gas ejiction opening that jet plate 7 is arranged, thus the surface of sheet glass 100 is heated.
Due to, be arranged between jet plate 7 on the downside of sheet glass e Foerderanlage 5 and sheet glass and be provided with roller-way 5, roller-way and air heat conduction velocity is between the two different, from causing when convective heating, between the upper and lower surface of sheet glass, and roller-way position and non-roller-way position exist certain temperature head, cause the mass defects such as glass edge warpage.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of glass heating furnace, the jet plate of this process furnace is wavy, high-temperature gas outlet is arranged on crest, and inlet mouth is arranged on trough, and corrugation pitch arranges consistent with orbital spacing, the central idle place blowing hot-air of corresponding two roller-ways of blowing mouth, compensate the rate of heating of this place's glass, thus glass is heated evenly everywhere, contribute to the quality of finished promoting toughened glass.
For achieving the above object, a kind of glass heating furnace disclosed in the utility model, it is included in the plenum chamber of the upper and lower both sides of glass conveying roller way or side setting, is arranged on the jet plate in plenum chamber exit; The cross section of jet plate is wavy, and by high-temperature gas outlet be arranged on jet plate crest place; Described Wave crest and wave trough is consistent with the spacing of glass conveying roller way in stove, and crest correspondence is arranged in the middle of two adjacent roller-ways, and trough then just corresponds to roller-way.
Further, the trough place of described jet plate is provided with freezing air recovery port.
Further, the wave-like of described jet plate is sinusoidal wave or rectangular wave.
When glass enters stove heating, very fast with roller-way contact site heat conduction velocity, temperature is higher, two roller-way middle part temperature are lower, cause glass to be heated inequality, produce detrimentally affect to the final product quality of glass, structure of the present utility model makes the central idle place blowing hot-air of corresponding two roller-ways of blowing mouth, thus relatively compensate for the rate of heating of this place's glass, thus it is more even that glass is heated everywhere, contributes to the quality of finished promoting toughened glass.

Fig. 3 is the Wave crest and wave trough structural representation consistent with the spacing of glass conveying roller way in stove;
Fig. 4 is the jet plate structural representation of sinusoidal waveform;
Fig. 5 is the jet plate structural representation of rectangular wave;
Fig. 6 is the glass heating furnace structural representation of semi-convective in embodiment 2.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
embodiment 1
As Figure 2-3, glass heating furnace in the present embodiment is full convection oven, it comprises top convection current case and the bottom convection current case of the upper and lower both sides being arranged on sheet glass rollgang 16, upper and lower convection current case comprises plenum chamber 11 and is arranged on the jet plate 13 in plenum chamber exit, the cross section of jet plate 13 is wavy, and high-temperature gas outlet 15 is arranged on crest 17 place of sheet glass 10.High-temperature gas exit on the crest 17 of the jet plate 13 on the plenum chamber of bottom convection current case is provided with nozzle 19.
Crest 17 trough 18 is consistent with the spacing of glass conveying roller way in stove 16, and crest 17 correspondence is arranged in the middle of two adjacent roller-ways, and 18, trough just corresponds to roller-way.That is, the center line L2 of the centre line L 1 of crest 17 roller-way adjacent with two is consistent, and the spacing a of crest 17 or trough 18 equals the spacing b of adjacent orbit.And the center line L3 of trough 18 is consistent with corresponding roller-way axis L4.
As shown in Figure 4, the wave-like of jet plate is sinusoidal wave; Or as shown in Figure 5, the wave-like of jet plate can also be rectangular wave.
embodiment 2
The present embodiment is substantially identical with embodiment 1 structure, and difference is:
As shown in Figure 6, the glass heating furnace in the present embodiment belongs to semi-convective process furnace, and it is only provided with top convection current case; The downside of glass conveying roller way 16 arranges heating unit 20, carries out radiation heating by the mode of radiation to glass sheet lower surface.
And jet plate in the present embodiment is identical with the jet plate structure of the top convection current case in embodiment 1.
The mounting structure of above-mentioned convection current case is applied to convection oven or semi-convective process furnace respectively, thus makes being heated of sheet glass more even, and then promotes the quality of finished of toughened glass.
Below only describe several preferred embodiments of the application by reference to the accompanying drawings, but the application is not limited thereto, every those of ordinary skill in the art are under the spirit not departing from the application, and any improvement made and/or distortion, all belong to the protection domain of the application.
