In glass heating furnace, for overcoming radiation heating to the slow and inhomogeneous shortcoming of low radiation (Low-E) glass (being commonly called as heat-reflecting glass) heating, the heating unit of employing radiation+convection current heats Low-E glass and can obtain good result.In the type of heating of present various radiation+convection current, take the effect of forcing the internal recycle convective heating as best.Can process in high quality the Low-E glass of extremely low E value (E 〉=0.02), the realization of this type of heating need to be installed the convection current air grid of two covers (each cover of upper and lower heating chamber) high temperature resistant (approximately 800 ℃) in process furnace, this makes the cost of process furnace significantly improve, and also makes maintenance become very complicated simultaneously.
Considering that low-radiation film only is plated in surface on glass, thereby only have upper surface can reflect away a large amount of radiant heat, so convective heating strength ratio bottom, process furnace top will exceed in the situation of an order of magnitude, some glass heating furnace has just been cancelled the convection current air grid device of process furnace bottom, the substitute is the high pressure gas that blow normal temperature with the electrical heater outside in the stove and drives that in stove, the way of hot gas flow realizes the convective heating of process furnace bottom.
This top is for forcing the internal recycle convective heating, the process furnace that high pressure gas are blown in bottom effect when the Low-E glass of heating E 〉=0.04 is also fine, the cost of process furnace is also than low many of the upper and lower process furnace that all fills the convection current air grid, but when constantly blowing into freezing air in the High Temperature Furnaces Heating Apparatus outside stove, the discharge of furnace gas can be taken away a large amount of heat, thereby brings again the new shortcoming that power consumption is large, production efficiency is not high.
Summary of the invention
In view of above-mentioned present situation, the utility model provides a kind of energy-saving hot-blast circulative convection hot type glass heating furnace, make on it heating chamber for forcing the internal recycle convection heating system, lower heating chamber is drawn onto the hot gas in lower furnace chamber outside stove in high-temperature blower outside stove, under the condition that keeps hot gas temperature, again air pressure is brought up to and to a certain degree sent in stove, stir the way of the hot gas flow in stove, realize the convective heating of lower heating chamber.
The technical solution of the utility model is: a kind of energy-saving hot-blast circulative convection hot type glass heating furnace, comprise upper furnace body and lower furnace body, quartzy roller-way is housed between upper and lower body of heater, the high-temperature blower of internal recycle convective heating is housed in described upper furnace body, is distributed with heating unit in described lower furnace body; The lower furnace body inner chamber that wherein is positioned at described quartzy roller-way bottom is provided with the circulative convection heating unit, and the circulative convection heating unit is connected with external High Temperature High Pressure blower fan with the lower furnace body inner chamber respectively.Like this,, from flowing to force circulation outside furnace in stove glass is heated by high temperature and high pressure gas.
During this is novel, related circulative convection heating unit, comprise an air inlet supervisor, this air inlet supervisor is communicated with again formation threeway inlet pipe with two branch's inlet pipe, connect vertical air inlet distribution piping of a symmetry on described two branch's inlet pipe, also comprise the be connected to each other jet arm of conducting of distributing installation between two vertical air inlet distribution pipings, be distributed with jet hole on described jet arm.
During this was novel, related upper and lower body of heater was closed furnace body.For guaranteeing that upper and lower body of heater internal recycle convective heating provides condition.
During this was novel, related lower furnace body one side was provided with two through holes that are connected with pipeline.Being convenient to pipeline is communicated with furnace chamber and circulative convection heating unit by through hole.Make high temperature and high pressure gas force outer circulation convective heating glass.
Effect of the present utility model is: because the High Temperature High Pressure blower fan of adopting in the lower furnace body outside is connected with the circulative convection heating unit that the body of heater inner chamber is set up, be combined by the high-temperature blower of circulative convection heating unit in original upper furnace body in lower furnace body, make high temperature and high pressure gas from flowing to the stove outer circulation in stove, form and force the internal recycle convective heating, enforcement is even to glass, rapid heating, has also reduced simultaneously energy consumption.
