Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass manufacturing technology, and in particular to a glass melting furnace. Background Technology
[0002] In the development of voltaic glass, the raw materials are typically placed in a crucible, which is then placed in a melting furnace to melt the raw materials into molten glass. After repeated stirring, debubbling, and clarification, the molten glass is poured into a pre-designed mold to form the glass. Once formed, the glass sample needs to be quickly transferred to an annealing furnace for annealing. Currently, after the glass is melted, it is poured into the mold to form the glass. However, the forming plate needs to be preheated to prevent the glass from cracking or losing transparency due to rapid supercooling of the molten glass. Furthermore, after forming, the hot glass plate needs to be quickly transferred to an annealing furnace for annealing. In this process, the forming plate and the annealing furnace are separate, requiring transfer between them, which presents problems such as high energy consumption and safety hazards during the transfer process.
[0003] Therefore, this application provides a glass melting furnace to solve the above-mentioned problems. Utility Model Content

[0030] refer to Figures 1 to 2As shown, this utility model discloses a glass melting furnace. According to a specific embodiment, it includes a melting furnace body located at the top, and a furnace cavity 30 is provided inside the melting furnace body. The melting sample crucible stored in the furnace cavity 30 is heated by a heating element 50 located at the furnace top 40. Below the furnace cavity 30, from top to bottom, are a melting sample storage platform and an annealing box 2. The melting sample storage platform is used to store the melting sample crucible, and the annealing box 2 is used for glass forming and annealing.
[0031] A lifting component is provided below the annealing box 2, which is used to move the annealing box 2 and the sample storage platform back and forth in the height direction.
[0032] Specifically, the lifting components include a scissor-type folding frame 6 and a hydraulic cylinder 7. The hydraulic cylinder 7 is connected to the scissor-type folding frame 6. The reciprocating motion of the hydraulic cylinder 7 drives the scissor-type folding frame 6 to move back and forth, so that the annealing box 2 and the sample storage platform can move back and forth in the height direction.
[0033] The sample storage platform works in conjunction with the furnace cavity 30 of the sample melting furnace body to conduct heat from the sample melting furnace body to the annealing box 2 for heating.
[0034] Specifically, the furnace body includes a furnace top 40, a furnace wall 9, and a heat insulation layer 8 connected to the furnace wall 9. The furnace top 40, furnace wall 9, and heat insulation layer 8 together form a furnace cavity 30. The heating element 50 is installed on the furnace top 40 and extends into the furnace cavity 30.
[0035] refer to Figure 2 As shown, the sample storage platform includes, from top to bottom, a high-temperature resistant storage platform 5, a heat-insulating boss 4, and a support platform 3. The high-temperature resistant storage platform 5 and the heat-insulating boss 4 can be made of ceramic materials such as alumina ceramics. The heat-insulating boss 4 abuts against the bottom of the heat insulation layer 8 of the sample furnace body, so that the furnace cavity 30 is sealed.
[0036] Specifically, the high-temperature storage platform 5, the heat-insulating protrusion 4, and the support platform 3 arranged from top to bottom have a stepped structure in cross-section. The bottom of the heat insulation layer 8 also has a stepped structure in cross-section. The two fit together to seal the furnace cavity 30 and prevent heat from leaking to the bottom as little as possible.
[0037] When the sample is melted, heat is transferred or radiated downwards from the support platform 3, and this heat will heat the annealing chamber, thereby reducing heat loss and improving the efficiency of heat use.
[0038] The annealing chamber 2 includes at least an outer shell 23 and a heating layer 21; the top of the outer shell 23 is connected to the bottom of the support platform 33, and the heating layer 21 is disposed on the inner side of the outer shell 23; a control panel 18 is provided on the outer side of the end plate 14 of the drawer 1. The control panel 18 is turned on and monitors the temperature inside the annealing chamber 2. Although the annealing chamber 2 receives heat by transmitting or radiating it downward through the melting furnace support platform 3, if the temperature requirement is not met, the control panel 18 is used to turn on the heating layer 21 to heat the annealing chamber 2 to reach the required temperature.
[0039] Furthermore, the annealing chamber 2 also includes a first insulation layer 22 and a second insulation layer 20. The outer shell 23, the first insulation layer 22, the heating layer 21, and the second insulation layer 20 are connected sequentially from the outside to the inside, and insulation is achieved through the first insulation layer 22 and the second insulation layer 20.
[0040] Furthermore, the annealing chamber 2 is provided with a guide rail 16 and a pull-out drawer 1. The drawer 1 is connected to the inner cavity of the annealing chamber 2 through the guide rail 16. The drawer 1 is slidably connected to the guide rail 16 and can reciprocate into or out of the cavity of the annealing chamber 2. The drawer 1 includes a bottom plate 12, a side plate 10, and an end plate 14. The two sides of the bottom plate 12 are respectively connected to the side plate 10, and the inner side of the end plate 14 is respectively connected to the bottom plate 12 and the side plate 10. A forming module 11 is provided on the bottom plate 12, and the bottom plate 12 is also slidably connected to the guide rail 16. The shape and size of the forming module 11 are set according to the size of the pre-formed glass block during glass manufacturing.
[0041] Furthermore, a third insulation layer 13 and a fourth insulation layer 17 are sequentially provided on the inner side of the end plate 14 from the outside to the inside, and a handle 15 is provided on the outer side of the end plate 14 to keep the molding module 11 warm.
[0042] When the molten glass is close to reaching the predetermined quality for pouring and forming, the temperature inside the annealing chamber 2 is monitored and activated slightly in advance via the control panel 18 located outside the end plate 14. The temperature of the annealing chamber 2, due to heat radiation from the melting furnace, is approximately above 60°C. If the temperature has not reached the preset annealing temperature, the heating layer 21 of the annealing chamber 2 is activated to heat the chamber until the internal temperature reaches the preset temperature. When the preset annealing temperature is reached, the melting sample storage platform and the annealing chamber 2 are lowered, the drawer 1 is pulled outwards, and the molten glass is poured into the forming module 11 for forming. After pouring the molten glass, the drawer 1 is pushed back into the cavity of the annealing chamber 2 for annealing.
[0043] The sample preparation process described above does not require separate heating of the molding carrier plate, effectively reducing energy consumption. Simultaneously, the temperature inside the annealing chamber 2 does not need to be raised from a low temperature during annealing, further reducing energy consumption. The sample preparation and annealing processes do not require transportation, effectively avoiding the possibility of burns from high-temperature glass blocks and significantly improving safety.
