The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.
A convection apparatus of a heating furnace having a multiple heating effect according to an embodiment of the present invention will be described with reference to fig. 1 to 5, including a convection tube assembly 2 disposed in a heating space 1 of the heating furnace, the convection tube assembly 2 including an upper layer of convection tubes 21, a central tube 22, and a lower layer of convection tubes 23;
the upper convection pipe 21 comprises an air inlet section 211 and a spiral section 212, wherein an input port of the air inlet section 211 extends to the outside of the heating space 1, and an output port of the air inlet section 211 is connected with an input port of the spiral section 212;
the coil section 212 is wound around the outer wall of the center tube 22, and the output port of the coil section 212 is connected to the input port of the center tube 22;
the lower convection pipe 23 comprises an extension 231 and a blowing section 232, and the input port of the extension 231 is connected with the output port of the central pipe 22; an output port of the extension section 231 is connected with an input port of the air blowing section 232, the air blowing section 232 is provided with a plurality of jet holes, and the jet holes face the roller shaft 12 arranged in the heating space 1;
the lower convection pipe 23 is located below the central pipe 22, and a heating wire 11 is arranged between the lower convection pipe 23 and the central pipe 22. So that the coil section 212 is positioned above the heating wire 11, improving the heating effect of the air in the coil section 212. Specifically, the heating wire 11 is fixed in the heating space 1.
In the convection device of the heating furnace with multiple heating effects, after entering from the input port of the air inlet section 211, the air enters the spiral section 212 through the air inlet section 211, and when passing through the spiral section 212, the heating wire 11 heats the air in the spiral section 212, and because the spiral section 212 is wound on the central tube 22, the path of the air path is prolonged, the heating time of the air is prolonged, and thus the air in the spiral section 212 can be fully heated; then, the air enters the central tube 22, the air is heated by the heating wire 11 again in the central tube 22, finally enters the air blowing section 232 through the extension section 231, and is blown to the glass on the roll shaft 12 through the jet holes of the air blowing section 232. Because the heated air is heated twice before being blown to the glass, the temperature of the air entering the blowing section 232 is ensured to be equal, and the glass can be uniformly heated.
In some embodiments, as shown in fig. 3 and 4, the inlet of the centertube 22 and the outlet of the centertube 22 are disposed at opposite ends of the centertube 22. The air can be heated by the heating wire 11 in the flowing process of the central tube 22, and the air entering the input port of the central tube 22 from the output port of the spiral section 212 needs to pass through the whole central tube 22 before being output from the output port of the central tube 22, so that the path of the air can be further prolonged, the heating time of the air is prolonged, and the air is heated more fully.
It is worth noting that the extension 231 extends in the direction of the roller shaft 12, as shown in fig. 1-3. As such, the blowing section 232 is disposed adjacent to the roller shaft 12. Because the convection tube of the existing convection device is far away from the glass, when hot air is blown to the glass, a part of heat is consumed in the space of the heating furnace, and the heating efficiency of the glass is low. Compared with the existing convection device, the convection device of the embodiment has the advantages that the distance between the air blowing section 232 and the roller shaft 12 is shorter, so that the distance between the air blowing section 232 and the glass is shorter, and hot air can be contacted with the glass after being blown out from the jet holes of the air blowing section 232, so that the temperature of the glass is increased. Specifically, in the present embodiment, the diameter of the air blowing section 232 is preferably 18mm, which is smaller than that of the air blowing section of the conventional convection apparatus having a diameter of 42 mm.
Optionally, the blowing section 232 is parallel to the roller 12. In this way, the blowing section 232 is parallel to the glass on the roll shaft 12, so that any one jet hole of the blowing section 232 blows the glass for the same distance, thereby enabling the glass to be heated uniformly.
Specifically, as shown in fig. 2, the heating space 1 is provided with a plurality of convection tube assemblies 2, and the blowing sections 232 of all the convection tube assemblies 2 are parallel to each other. The plurality of convection tube assemblies 2 operate simultaneously to heat the glass, thereby improving the heating efficiency.
Preferably, as shown in fig. 3, the inlet of the central tube 22 is opened on the upper surface of the central tube 22, and the outlet of the central tube 22 is opened on the lower surface of the central tube 22. Therefore, the route of the air path can be further prolonged, so that the heating time of the air is prolonged, and the air is heated more fully.
In some embodiments, as shown in FIG. 3, the central tube 22 can be removably provided with either a plug 221 or a plug 222 at each end. When the convection device is in operation, the blocking plate 221 or the blocking head 222 is arranged to prevent hot air in the central tube 22 from leaking; in case of emergency, by detaching the blocking plate 221 or the blocking head 222, the hot air in the convection apparatus can be rapidly exhausted, and then the convection apparatus is shut down.
It is noted that, as shown in fig. 3, the output port of the extension 231 is connected to the input port of the blowing section 232 via a flange 233. Thus, the extension 231 and the blowing section 232 can be conveniently detached, and the blowing section 232 can be conveniently maintained or replaced.
Other configurations and operations of a convection apparatus of a heating furnace having a multiple heating effect according to an embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.
