Abstract
The utility model discloses a convection-type heating furnace jet flow plate, wherein a jet flow plate is arranged at outlets of an upper gas collecting box and a lower gas collecting box of a convection-type heating furnace; the cross section of the jet flow plate is wavy; a high-temperature gas outlet is arranged at the wave peak close to a glass plate; a cold air recycling opening is arranged at the wave valley of the jet flow plate far away from the glass plate; and the high-temperature gas outlet on the wave peak of the jet flow plate at the lower gas collecting box is provided with a jet nozzle. According to the utility model, through utilizing the wavy jet flow plate, the high-temperature gas outlet is arranged at the wave peak of the jet flow plate, and the cold air recycling opening is arranged at the wave valley of the jet flow plate, thus the high-temperature gas can heat the surface of the glass plate effectively, also the high-temperature gas jet nozzle is also additionally arranged at the high-temperature gas outlet on the wave peak on the jet flow plate of the lower gas collecting box, the distance from the high-temperature gas to the lower surface of the glass plate is shortened, the upper surface and the lower surface of the glass plate are heated uniformly, the production efficiency is improved, and the heating effect is improved.
Description
Technical field
The utility model relates to the aerofoil that uses in a kind of convection oven.
Background technology
In the prior art; The structure of convection oven is as shown in Figure 1; Comprise: the furnace chamber of forming by 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 comprises glass sheets device 5, is used for sheet glass is transferred to plug for outlet 4 from advancing fire door 3; Be the glass sheets passage from advancing fire door to the passage of plug for outlet; Be provided with sealing plenum chamber 6 and the jet plate 7 that is arranged on plenum chamber 6 exits in the both sides up and down of glass sheets roller-way 5, the gas in the plenum chamber 6 is ejected on the surface of the sheet glass 100 that is positioned on the glass sheets device 5 through the high-temperature gas ejiction opening that is provided with on the jet plate 7, thereby the surface of sheet glass 100 is heated.
Because; Be arranged between jet plate 7 and the sheet glass of glass sheets device 5 downsides and be provided with roller-way; Feasible high-temperature gas by 7 ejections of downside jet plate; When sheet glass is heated, can cause certain calorific loss, cause on glass, lower surface to have certain temperature head, cause that glass edge portion warpage influences the glass processing quality because spaced interval is excessive.
The utility model content
Existing problem when solving that the convection type glass plate heating furnace heats sheet glass in the prior art, it is more even that the sheet glass upper and lower surfaces is heated, and improve in the convection oven utilising efficiency by the high-temperature gas that sprays in the plenum chamber.
A kind of convection oven jet plate of the utility model; Said jet plate is arranged on the upper and lower plenum chamber exit of convection oven; The cross section of jet plate is wavy; And high-temperature gas outlet is arranged on the crest place of sheet glass, and freezing air to be reclaimed mouth be arranged on trough place away from the jet plate of sheet glass, the high-temperature gas exit on the crest of the jet plate of plenum chamber down is provided with nozzle.
Further, said jet plate cross section is the waviness of rule.
Further, said jet plate cross section is sinusoidal waveform or square waveform.
Further, an end of said jet plate through fixation clip, the other end through being bolted on the said upper and lower plenum chamber.
Further, said jet plate cross section is the random sea shape wave.
Further, said nozzle and aerofoil are riveted joint or screw type of attachment.
The utility model is through using the waviness jet plate; And high-temperature gas outlet is arranged on the crest place of sheet glass; Freezing air is reclaimed mouth be arranged on trough place away from the jet plate of sheet glass; High-temperature gas can more effectively be heated glass pane surface, and the high-temperature gas exit at the crest place on the jet plate of following plenum chamber also set up the high-temperature gas nozzle, closely the sheet glass lower surface has been heated.Shorten the distance that high-temperature gas arrives the sheet glass lower surface, solved in the prior art sheet glass lower surface bad problem of being heated, made sheet glass upper and lower surfaces thermally equivalent, improved production efficiency, improved heats.

Embodiment
Embodiment 1
Shown in Fig. 2-5; In the present embodiment in the convection oven; On upper and lower plenum chamber 6 exits, be provided with jet plate 7, an end of jet plate 7 is fixing through the retaining plate on the upper and lower plenum chamber 6 11, and the other end is fixed on the upper and lower plenum chamber 6 through bolt 12.The cross section of jet plate 7 is the consistent square waveform of Wave crest and wave trough width; Have some through holes on it, be arranged on the crest, promptly be installed on the plenum chamber 6 after; Through hole near the position of sheet glass 100 is a high-temperature gas ejiction opening 9, and the through hole on the trough is a gas recovery mouth 10.Also be provided with nozzle 8 on the jet plate 7 of following plenum chamber 6, nozzle 8 can be realized sheet glass 100 lower surfaces are closely heated.
Embodiment 2
Being provided with among position and set-up mode and the embodiment 1 of jet plate 7 in the present embodiment is identical, and its difference is that as shown in Figure 6, the cross section of the jet plate 7 in the present embodiment is a sinusoidal waveform.
The waviness section of the jet plate 7 in the utility model can be the waviness of the rule that limited among above-mentioned two embodiment, also can be inconsistent random sea shape wave.Because of the jet plate of plenum chamber 6 in the upper furnace body 27 directly in the face of being heated sheet glass 100; And be separated with glass sheets roller-way 5 mutually between the jet plate 7 of plenum chamber 6 and sheet glass 100 lower surfaces in the lower furnace body 1, have certain distance between following jet plate and the sheet glass lower surface.Therefore, be heated evenly in order to make sheet glass 100 upper and lower surfaces, the shape of the jet plate 7 of plenum chamber 6 can be processed different shapes in the upper and lower body of heater.
