Abstract
Description
Technical Field
[0001] The present application relates to the technical field of glass production equipment, and in particular to a heat preservation device and a glass melting furnace. Background Art
[0002] In the related technology, during the production process of photovoltaic glass, high-temperature glass in a molten state flows out from the overflow port of the photovoltaic rolled glass melting furnace, passes through the flow channel and enters the calender for rolling and forming. The temperature of the high-temperature glass on both sides is relatively low when it flows out, and the temperature of the high-temperature glass at the edge drops, resulting in increased viscosity and poor fluidity. Long-term retention is very likely to form crystallized material, which can easily damage the roller of the calender.
[0003] At present, clay bricks are placed on both sides of the overflow to solve the problem of heat loss at the edges and thus achieve the purpose of heat preservation of the molten glass in the flow channel. Clay bricks have a certain heat absorption property, resulting in most of the heat emitted from the overflow being absorbed by the clay bricks when it is dissipated to the clay bricks, and there is basically no heat reflection. Therefore, the effect of increasing the temperature of the molten glass at the edge is not obvious, and it cannot solve the defects caused by the low temperature of the molten glass in the flow channel. The temperature of the molten glass on both sides of the flow channel will be raised regularly by burning edge fires.
[0004] The above-mentioned related technologies still have the following technical problems in the specific implementation methods: the flame is prone to burn unevenly during the edge fire process, which can easily cause local overheating of the molten glass on both sides of the flow channel; and long-term burning during the edge fire process can easily produce ash, which can easily contaminate the high-temperature glass in the flow channel after falling, and there is a risk of damaging the roller body; and long-term burning increases cost consumption.

[0044] See also Figure 1-Figure 4 As shown, one embodiment of the present application provides a heat preservation device for being installed on at least one side of a flow channel 310 of a glass melting furnace 300 for guiding molten glass flowing out of an overflow port. The heat preservation device includes a base and a heat preservation material. The base is installed on at least one side of the flow channel 310. The base is used to prevent heat loss on one side of the flow channel 310, thereby increasing the temperature of the molten glass on one side of the flow channel 310.
[0045] As an embodiment, the insulation is filled in the base. Since the insulation is filled in the base, the insulation device will not fall off or be damaged during use, which reduces the loss of the insulation during use. At the same time, through the setting of the insulation, the insulation reduces the conduction of heat in the base, thereby reducing the heat loss of the molten glass on both sides of the flow channel 310.
[0046] In the above solution, the insulation is filled in the base. Of course, in a specific application, as an alternative implementation, the insulation is fixed on the side of the base facing away from the flow channel 310. The insulation on the side of the base facing away from the flow channel 310 blocks cold air from entering the flow channel 310 and blocks the loss of heat in the flow channel 310. At the same time, since the insulation is fixed on the side of the base facing away from the flow channel 310, the convenience of the insulation device during production and assembly is improved.
[0047] As an embodiment, the heat preservation device includes two bases, which are distributed on opposite sides of the flow channel 310 to reduce heat loss on both sides of the flow channel 310. Of course, in specific applications, the number of bases is not limited to two. For example, there may be three bases distributed on opposite sides of the flow channel 310, with two bases arranged on one side of the flow channel 310 and one base arranged on the other side. There may also be four bases distributed on opposite sides of the flow channel 310, with two bases arranged on one side and the other two bases arranged on the other side.
[0048] Each base is provided with a heat-insulating material. The heat-insulating material reduces heat conduction and reduces heat loss from the molten glass on both sides of the flow channel 310. Since the heat-insulating material is provided inside each base, the heat-insulating device reduces the loss of the heat-insulating material during use, thereby improving the safety and service life of the heat-insulating device.
[0049] In the above solution, each base is filled with insulation. Of course, in a specific application, as an alternative embodiment, insulation is provided on the side of each base facing away from the overflow. By providing insulation on the side of each base facing away from the overflow, the overall convenience of the insulation device during production and assembly is improved.

The first cavity further includes a second sub-cavity 121 formed within the second plate 120, and the first thermal insulation filler further includes a second sub-insulation filler 122 filled within the second sub-cavity 121. The arrangement of the second plate 120 and the second sub-insulation filler 122 is used to reduce heat loss within the flow channel 310 above one side of the flow channel 310, thereby increasing the temperature of the molten glass within the flow channel 310.
[0053] As an embodiment, the first shell 100 further includes a third plate 130, which extends from the bottom of the first plate 110 toward the side of the first plate 110 facing away from the flow channel 310. The first cavity further includes a third sub-cavity 131 formed within the third plate 130, and the first thermal insulation filler further includes a third sub-thermal insulation filler 132 filled within the third sub-cavity 131. The third plate 130 is used to support the first plate 110 and improve the stability of the first plate 110. The third plate 120 can be placed directly on the side of the flow channel 310, or it can be fixed to the side of the flow channel 310 by other fixing devices to improve the stability of the first shell 100.

The fourth plate 210 and the first plate 110 are arranged side by side along the guiding direction of the flow channel 310. The fourth plate 210 and the first plate 110 are detachably connected. The fifth plate 220 extends from the top of the fourth plate 210 above the flow channel 310. Through the arrangement of the fourth plate 210 and the fifth plate 220, the fourth plate 210 is arranged on one side of the flow channel 310 to insulate the flow channel 310 to reduce heat loss of the molten glass on one side of the flow channel 310. The fifth plate 220 is arranged above one side of the flow channel 310 to reduce heat loss above one side of the flow channel 310.
[0056] The second cavity includes a fourth sub-cavity 211 formed within the fourth plate 210 and a fifth sub-cavity 221 formed within the fifth plate 220. The second thermal insulation filler includes a fourth sub-cavity 212 filled within the fourth sub-cavity 211 and a fifth sub-cavity 222 filled within the fifth sub-cavity 221. The fourth sub-cavity 212 reduces heat loss on one side of the flow channel 310, while the fifth sub-cavity 221 reduces heat loss above one side of the flow channel 310.
[0057] See also Figure 1 、 Figure 2 As shown, as an embodiment, one of the first shell 100 and the second shell 200 includes a connecting shaft 140, and the other includes a connecting hole 230.
