[0002] When conducting glass research and development experiments, glass raw materials need to be loaded into a crucible, which is then placed in a high-temperature furnace for heating. The process of melting various glass raw materials into glass is observed.

[0039] A crucible 401 is placed on a support platform 2 inside the heating furnace 1, and the glass raw material is heated in the crucible 401. An observation hole 4 is located above the support platform 2. The inside of the crucible 401 can be observed from a top-down angle through the camera component 5. The observation range is wide, and the high-temperature camera device can record the glass melting process and clearly observe the removal of bubbles in the glass, thereby achieving a comprehensive observation of the glass melting state. Multiple crucibles 401 can be placed on the support platform 2 at the same time for comparison.

[0040] In this invention, the observation hole 4 is a fan-shaped through hole, which ensures the viewing angle while reducing the area of ​​the heat-insulating lens 6 contaminated by the volatile substances of the glass raw materials, and at the same time reduces the heat loss of the heating furnace 1.

[0041] A purging assembly is installed on one side of the heat-insulating lens 6. The purging assembly purifies the heat-insulating lens 6 with argon gas, which effectively improves the pollution and corrosion of the heat-insulating lens 6 by volatile substances.

[0043] The base plate 102, top plate 3, and two side plates 101 are an integral structure; the observation hole 4 has a fan-shaped cross-section and is a through hole; the larger end of the observation hole 4 is connected to the heating chamber 103; the smaller end of the observation hole 4 is connected to the camera assembly 5, and the diameter of the smaller end of the observation hole 4 is larger than the lens diameter of the camera 502; the observation hole 4 is located on the top of the support platform 2; in this embodiment, the heating furnace 1 is heated by resistance, and the silicon molybdenum rod heating element is evenly distributed around the furnace. It is connected to the power supply by wires and controlled by zones, which can quickly raise the temperature and ensure uniform temperature inside the furnace; the crucible 401 is placed in the heating chamber 103 to heat the glass raw material.

[0044] The camera assembly 5 includes a mounting housing 501; a camera 502 is housed in the mounting housing 501; a heat-insulating lens 6 is connected to the mounting housing 501; and the heat-insulating lens 6 is located between the camera 502 and the observation hole 4.

[0045] The mounting housing 501 is made of stainless steel; the camera 502 can be a Hikvision DS-NXCN3A204 high-temperature resistant camera; the heat-insulating lens 6 can be a high-temperature resistant quartz glass lens; the heat-insulating lens 6 is fixedly connected to the end of the mounting housing 501 through a slot; the mounting position of the heat-insulating lens 6 is aligned with the observation hole 4; the camera 502 observes the crucible 401 in the heating chamber 103 through the heat-insulating lens 6 and the observation hole 4.

[0046] The mounting housing 501 has a mounting hole 503; the camera 502 is disposed in the mounting hole 503; the heat-insulating lens 6 is disposed at the end of the mounting hole 503; the mounting housing 501 includes a mounting side plate 504;

[0047] The purging assembly includes an air supply pipe 505; the air supply pipe 505 is disposed in the mounting side plate 504; the end of the mounting side plate 504 near the top plate 3 is provided with an inclined end face 601; the air supply pipe 505 includes an air outlet end 602; the air outlet end 602 is connected to the inclined end face 601, and the air outlet end 602 is disposed on one side of the heat insulation lens 6.

[0048] The camera 502 is installed in the mounting hole 503; the heat-insulating lens 6 is fixedly connected to the end of the mounting hole 503; the bottom of the mounting side plate 504 is provided with an inclined end face 601; the inclined end face 601 is set along the edge of the observation hole 4; the gas supply pipe 505 is located inside the mounting side plate 504, one end of the gas supply pipe 505 is connected to the gas supply pump, and the gas outlet 602 of the gas supply pipe 505 is fixedly connected to the inclined end face 601 by a buckle; the gas outlet 602 blows argon gas toward the heat-insulating lens 6; thereby avoiding contamination of the heat-insulating lens 6 by volatile substances.

[0049] An air supply pump is connected to the end of the air supply pipe 505 away from the air outlet 602; argon gas is provided in the air supply pipe 505; an exhaust hole 603 is provided on the inclined end face 601.

[0050] The gas supply pump delivers argon gas to the gas supply pipe 505, and the gas outlet 602 blows argon gas toward the heat-insulating lens 6, forming a protective argon gas curtain on the surface of the heat-insulating lens 6. Since argon gas is stable and does not react with volatiles, it can effectively prevent volatiles from contacting the heat-insulating lens 6, thereby avoiding the adhesion and contamination of the heat-insulating lens 6 by volatiles. At the same time, the exhaust hole 603 provided on the inclined end face 601 can promptly discharge the argon gas containing volatiles after blowing, so that the protective gas curtain is continuously renewed and maintains a good protective effect.

[0051] The side panel 504 is provided with insulation cotton 7 on the side away from the mounting hole 503; the insulation cotton 7 is connected to the top panel 3.

[0052] The insulation cotton 7 is fixedly connected to the side of the mounting shell 501 and to the top plate 3, thereby blocking the contact gap between the mounting shell 501 and the top plate 3 and reducing the heat loss inside the heating furnace 1.

[0053] A cover plate 8 is provided at the end of the mounting hole 503 away from the heat insulation lens 6; an air outlet 801 is provided on the cover plate 8; an air inlet 802 is provided on the mounting side plate 504; a cooling fan 803 is connected to the air outlet 801; both the air outlet 801 and the air inlet 802 are connected to the mounting hole 503.

[0054] The cooling fan 803 is installed at the air outlet 801 on the cover plate 8. After being powered on, it draws air out of the mounting hole 503 through the air outlet 801, creating a negative pressure environment in the mounting hole 503. At this time, outside air is drawn into the mounting hole 503 through the air inlet 802, forming an airflow channel from the air inlet 802 to the air outlet 801. The heat on the surface of the camera 502 installed in the mounting hole 503 is absorbed and carried away by the flowing air. Fresh cold air is continuously replenished and continuously exchanges heat with the camera 502, thereby achieving effective heat dissipation of the camera 502 and ensuring its stable operation within a suitable temperature range.

[0055] The mounting housing 501 is provided with a cooling water pipe 9; the mounting side plate 504 is provided with an inlet pipe 901 and an outlet pipe 902; one end of the cooling water pipe 9 is connected to the inlet pipe 901, and the other end of the cooling water pipe 9 is connected to the outlet pipe 902.

[0056] The cooling water pipe 9 installed inside the housing 501 forms a circulating water circuit through the inlet pipe 901 and outlet pipe 902 on the mounting side plate 504. The inlet pipe 901 is connected to a water pump, which pumps cooling water into the inlet pipe 901. When the cooling water flows in from the inlet pipe 901, it enters the cooling water pipe 9 under pressure. Since the cooling water pipe 9 tightly surrounds the mounting hole 503, and the camera 502 is installed inside the mounting hole 503, the water in the cooling water pipe 9 can exchange heat with the heated camera 502, absorbing the heat emitted by the camera 502. The water that has absorbed the heat flows along the cooling water pipe 9 and finally flows out from the outlet pipe 902. At the same time, new low-temperature water is continuously replenished from the inlet pipe 901, continuously carrying away the heat generated by the camera 502. Through this circulating cooling method, the temperature of the camera 502 is effectively reduced, ensuring that it operates within a stable operating temperature range and avoiding the impact of excessive temperature on the performance and service life of the camera 502.

[0057] The base plate 102 is provided with a clearance hole 201; the support platform 2 is provided in the clearance hole 201; the bottom of the support platform 2 is provided with a lifting cylinder 202; the lifting cylinder 202 is provided with a piston rod 203; the piston rod 203 is connected to the support platform 2.

[0058] When the lifting cylinder 202 receives a control signal and starts working, it pushes the piston rod 203 to extend and retract. The piston rod 203 is fixedly connected to the support platform 2. The extension and retraction of the piston rod 203 will cause the support platform 2 to move up and down along the axial direction of the clearance hole 201. When the piston rod 203 extends, the support platform 2 rises, which can lift the crucible 401 placed on the support platform 2 to a specified height. When the piston rod 203 retracts, the support platform 2 descends, so that the crucible 401 returns to the initial position, thereby realizing the flexible adjustment of the height of the support platform 2.

[0059] A controller 104 is provided on the side plate 101; the controller 104 is connected to the lifting cylinder 202.

[0060] The controller 104 can be a microcontroller; the controller 104 is equipped with a control panel; the operator can control the lifting cylinder 202 to work through the controller 104.

[0061] The specific workflow of this utility model is as follows:

[0062] A crucible 401 is placed on a support platform 2 inside the heating furnace 1, and the glass raw material is heated in the crucible 401. An observation hole 4 is located above the support platform 2. The inside of the crucible 401 can be observed from a top-down angle through the camera component 5. The observation range is wide, and the high-temperature camera device can record the glass melting process and clearly observe the removal of bubbles in the glass, thereby achieving a comprehensive observation of the glass melting state. Multiple crucibles 401 can be placed on the support platform 2 at the same time for comparison.

[0063] In this invention, the observation hole 4 is a fan-shaped through hole, which ensures the viewing angle while reducing the area of ​​the heat-insulating lens 6 contaminated by the volatile substances of the glass raw materials, and at the same time reduces the heat loss of the heating furnace 1.

[0064] A purging assembly is installed on one side of the heat-insulating lens 6. The purging assembly purifies the heat-insulating lens 6 with argon gas, which effectively improves the pollution and corrosion of the heat-insulating lens 6 by volatile substances.
