Description

Technical Field

[0001] This utility model relates to the field of glass tube processing technology, and in particular to a gas-fired annealing furnace for processing high borosilicate glass tubes. Background Technology

[0002] High borosilicate glass tubes are high-performance scientific research and experimental glass tubes, designed to meet various scientific research and industrial needs. Their main components are silicon dioxide and boron oxide, possessing excellent heat resistance, chemical corrosion resistance, and optical transparency. To reduce or eliminate stress generated during the forming or hot processing of high borosilicate glass tubes and improve their performance, annealing is necessary. The annealing process includes several key steps: annealing temperature (typically set at 560±10℃), holding at this temperature for a period of time relaxes and disperses internal stresses, thereby eliminating or reducing permanent stresses); annealing time (holding at the annealing temperature for a specified period, typically 3 minutes to eliminate 95% of the stress, and 10 minutes to eliminate 99%); and cooling process (after annealing, the glass product needs to be cooled at an appropriate rate to prevent the generation of new stresses).

[0003] Current annealing furnaces still have shortcomings. In the cooling step of the annealing process for high borosilicate glass tubes, the current annealing furnaces cool directly in an open space outside the furnace. This causes the heat generated during cooling to escape and cannot effectively collect and utilize this excess heat. Consequently, the annealing furnace has low thermal energy utilization rate and increases energy consumption. Summary of the Invention

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Reference Figures 1 to 6 The present invention provides a further description of an embodiment of a gas-fired annealing furnace for processing high borosilicate glass tubes.

[0025] A gas-fired annealing furnace for processing high borosilicate glass tubes includes a furnace shell 1, a glass tube body 2, and further includes:

[0026] A sealing assembly is disposed on the furnace shell 1, the sealing assembly comprising:

[0027] A servo motor 8 is mounted on the furnace shell 1 and is fixedly connected to the furnace shell 1.

[0028] A lead screw 9 is mounted on the furnace shell 1 and rotatably connected to the furnace shell 1. The lead screw 9 is fixedly connected to the output shaft of the servo motor 8.

[0029] A sealing door 10 is disposed on the furnace shell 1 and slidably connected to the furnace shell 1. The sealing door 10 is threadedly connected to the lead screw 9.

[0030] Start the servo motor 8. The output shaft of the servo motor 8 rotates, which drives the lead screw 9, which is fixedly connected to the output shaft of the servo motor 8, to rotate. This drives the sealing door 10, which is threadedly connected to the lead screw 9 and restricted by the sliding connection of the furnace shell 1, to slide until the end of the sealing door 10 near the ground is in close contact with the end of the material conveying base 11 away from the ground. Then, turn off the servo motor 8.

[0031] A material conveying assembly, disposed on the furnace shell 1, is used for automatically conveying the glass tube body 2. The material conveying assembly includes:

[0032] Material conveying base 11 is disposed on the furnace shell 1 and fixedly connected to the furnace shell 1;

[0033] A drive motor 12 is mounted on the material conveying base 11 and is fixedly connected to the material conveying base 11;

[0034] A threaded rod 13 is disposed on the material conveying base 11 and rotatably connected to the material conveying base 11. The threaded rod 13 is fixedly connected to the output shaft of the drive motor 12.

[0035] The material conveying platform 14 is disposed on the material conveying base 11 and is slidably connected to the material conveying base 11. The threaded rod 13 of the material conveying platform 14 is threadedly connected.

[0036] Start the drive motor 12. The output shaft of the drive motor 12 rotates, which drives the threaded rod 13, which is fixedly connected to the output shaft of the drive motor 12, to rotate. This drives the material conveying platform 14, which is threadedly connected to the threaded rod 13, to rotate. Since the material conveying platform 14 is restricted by the slidingly connected material conveying base 11, it can only slide. When the material conveying platform 14 slides to the heating component, turn off the drive motor 12.

[0037] Reference Figures 1 to 6 A rotating assembly, disposed on the conveying assembly, is used to automatically rotate several glass tube bodies 2. The rotating assembly includes:

[0038] Mounting slot 15 is provided on the material conveying platform 14;

[0039] A micro motor 16 is mounted on the mounting slot 15 and is fixedly connected to the material conveying platform 14;

[0040] The drive sprocket 17 is mounted on the output shaft of the micro motor 16 and is fixedly connected to the output shaft of the micro motor 16;

[0041] A rotating shaft 18 is disposed on the material conveying platform 14 and is rotatably connected to the material conveying platform 14;

[0042] Driven sprocket 19 is disposed on the rotating shaft 18 and is fixedly connected to the rotating shaft 18;

[0043] Chain 20 is disposed on the drive sprocket 17 and meshes with the drive sprocket 17; chain 20 is also meshed with the driven sprocket 19.

[0044] The loading tray 21 is disposed on the material handling platform 14 and is rotatably connected to the material handling platform 14. The loading tray 21 is fixedly connected to the rotating shaft 18.

[0045] When the micro motor 16 is started, the output shaft of the micro motor 16 rotates, which drives the drive sprocket 17 fixedly connected to the output shaft of the micro motor 16 to rotate, thereby driving the chain 20 meshing with the drive sprocket 17 to move. The movement of the chain 20 drives the driven sprocket 19 meshing with the chain 20 to rotate, thereby driving the rotating shaft 18 fixedly connected to the driven sprocket 19 to rotate. The rotation of the rotating shaft 18 drives the loading plate 21 fixedly connected to the rotating shaft 18 to rotate.

[0046] Reference Figures 1 to 6 A fixing component, disposed on the rotating component, is used to clamp the glass tube body 2. The fixing component includes:

[0047] A heat-conducting column 22 is disposed on the tray 21 and fixedly connected to the tray 21;

[0048] Mounting hole 23 is provided on the heat-conducting column 22 and is fixedly connected to the heat-conducting column 22;

[0049] Spring 24 is disposed on the mounting hole 23 and fixedly connected to the heat-conducting column 22;

[0050] A connecting block 25 is disposed on the mounting hole 23 and slidably connected to the heat-conducting column 22; the connecting block 25 is fixedly connected to the spring 24.

[0051] An arc-shaped support plate 26 is disposed on the connecting block 25 and is fixedly connected to the connecting block 25.

[0052] Push the arc-shaped support plate 26 by hand to move it towards the heat-conducting column 22. The movement of the arc-shaped support plate 26 causes the connecting block 25, which is fixedly connected to the arc-shaped support plate 26, to move until the connecting block 25 is fully inserted into the mounting hole 23. Then, put the glass tube body 2 over the arc-shaped support plate 26 and release it. The fixing block rebounds away from the heat-conducting column 22 under the elastic force of the fixedly connected spring 24, thereby causing the connecting block 25, which is fixedly connected to the spring 24, to move away from the heat-conducting column 22. The movement of the connecting block 25 causes the arc-shaped support plate 26, which is fixedly connected to the connecting block 25, to move until the arc-shaped support plate 26 is tightly attached to the inner wall of the glass tube body 2, achieving the fixing effect.

[0053] A heating assembly, disposed on the heating component, is used to heat the glass tube body 2. The heating assembly includes:

[0054] Mounting base 27 is disposed on the furnace shell 1 and fixedly connected to the furnace shell 1;

[0055] A gas heater 28 is mounted on the mounting base 27 and is fixedly connected to the mounting base 27.

[0056] An air vent 29 is provided on the furnace shell 1;

[0057] The first mounting bracket 30 is disposed on the air outlet 29 and is fixedly connected to the furnace shell 1;

[0058] The electric fan 31 is mounted on the first mounting bracket 30 and is fixedly connected to the first mounting bracket 30.

[0059] A heat transfer box 32 is mounted on the furnace shell 1 and is fixedly connected to the furnace shell 1.

[0060] A heat transfer pipe 33 is disposed on the heat transfer box 32 and fixedly connected to the heat transfer box 32. The heat transfer pipe 33 is fixedly connected to the second valve 7.

[0061] Open the second valve 7 and start the electric fan 31. The heat in the heat storage tank 5 is transferred to the heat transfer box 32 by the airflow generated by the electric fan 31 through the heat transfer pipe 33. Then, the heat transfer box 32 passes through the air outlet 29 and is blown by the electric fan 31 onto the surface of the rotating glass tube body 2 for preheating. Next, start the gas heater 28. The heat generated by the gas heater 28 is blown by the electric fan 31 onto the surface of the rotating glass tube body 2 for the heating and annealing process.

[0062] Reference Figures 1 to 6 A cooling assembly, located on the furnace shell 1, for accelerating the cooling of the glass tube body 2 after annealing. The cooling assembly includes:

[0063] Ventilation hole 34 is provided on the furnace shell 1;

[0064] A dust cover 35 is disposed on the ventilation hole 34 and is fixedly connected to the furnace shell 1;

[0065] The second mounting bracket 36 is disposed on the vent 34 and is fixedly connected to the furnace shell 1;

[0066] A cooling fan 37 is mounted on the second mounting bracket 36 and is fixedly connected to the second mounting bracket 36.

[0067] Heat exhaust hole 38 is provided on the furnace shell 1;

[0068] The third mounting bracket 39 is disposed on the heat exhaust hole 38 and is fixedly connected to the furnace shell 1;

[0069] A heat exhaust fan 40 is mounted on the third mounting bracket 39 and is fixedly connected to the third mounting bracket 39.

[0070] A heat recovery component, disposed on the furnace shell 1, is used to recover excess heat energy and use the excess heat energy for preheating and auxiliary heating of the glass tube body 2. The heat recovery component includes:

[0071] The heat collection box 3 is disposed on the furnace shell 1 and is fixedly connected to the furnace shell 1;

[0072] Heat exhaust pipe 4 is installed on the heat collection box 3 and fixedly connected to the heat collection box 3. Heat exhaust pipe 4 is fixedly connected to the first valve 6.

[0073] A heat storage tank 5 is disposed on the furnace shell 1 and fixedly connected to the furnace shell 1;

[0074] The first valve 6 is installed on the heat storage tank 5 and is fixedly connected to the heat storage tank 5;

[0075] The second valve 7 is installed on the heat storage tank 5 and is fixedly connected to the heat storage tank 5.

[0076] The cooling fan 37 and the exhaust fan 40 are started. The airflow generated by the cooling fan 37 and the exhaust fan 40 quickly carries the heat on the rotating glass tube body 2 through the exhaust hole 38 to the heat collection box 3. The first valve 6 is opened. At this time, the heat rises from the exhaust pipe 4 and enters the heat storage tank 5 through the first valve 6, realizing the cooling and heat recovery effects.

[0077] Reference Figures 1 to 6Through the cooperation of the cooling component, the heat recovery component, and the heating component, the cooling fan 37 and the exhaust fan 40 in the cooling component first collect the heat on the glass tube body 2 and store it in the heat storage tank 5 by the heat collection box 3 and the exhaust pipe 4 in the heat recovery component. Then, the electric fan 31 in the heating component extracts the heat stored in the heat storage tank 5 for preheating and auxiliary heating of the glass tube body 2, so that the excess heat energy can be fully utilized, thereby improving the utilization rate of heat energy in the annealing furnace and reducing the energy consumption of the annealing furnace.

[0078] Working principle: Refer to Figures 1 to 6 Push the arc-shaped support plate 26 by hand to move it towards the heat conduction column 22. The movement of the arc-shaped support plate 26 drives the connecting block 25, which is fixedly connected to the arc-shaped support plate 26, to move until the connecting block 25 is completely inserted into the mounting hole 23. Then, put the glass tube body 2 on the outside of the arc-shaped support plate 26 and release it. The fixing block rebounds away from the heat conduction column 22 under the elastic force of the fixedly connected spring 24, thereby driving the connecting block 25, which is fixedly connected to the spring 24, to move away from the heat conduction column 22. The movement of the connecting block 25 drives the arc-shaped support plate 26, which is fixedly connected to the connecting block 25, to move until the arc-shaped support plate 26 is tightly attached to the inner wall of the glass tube body 2, achieving the fixing effect.

[0079] Start the drive motor 12. The output shaft of the drive motor 12 rotates, which drives the threaded rod 13 fixedly connected to the output shaft of the drive motor 12 to rotate, thereby driving the material conveying platform 14 threadedly connected to the threaded rod 13 to rotate. Since the material conveying platform 14 is restricted by the sliding connection of the material conveying base 11, it can only slide. When the material conveying platform 14 slides to the heating component, turn off the drive motor 12 and start the servo motor 8. The output shaft of the servo motor 8 rotates, which drives the lead screw 9 fixedly connected to the output shaft of the servo motor 8 to rotate, thereby driving the sealing door 10 threadedly connected to the lead screw 9 and restricted by the sliding connection of the furnace shell 1 to slide until the end of the sealing door 10 near the ground is in close contact with the end of the material conveying base 11 away from the ground. Then turn off the servo motor 8.

[0080] Reference Figures 1 to 6When heating is performed, the micro motor 16 is started. The output shaft of the micro motor 16 rotates, which drives the drive sprocket 17 fixedly connected to the output shaft of the micro motor 16 to rotate. This drives the chain 20 meshing with the drive sprocket 17 to move. The chain 20 moves, which drives the driven sprocket 19 meshing with the chain 20 to rotate. This drives the rotating shaft 18 fixedly connected to the driven sprocket 19 to rotate. The rotating shaft 18 rotates, which drives the carrying tray 21 fixedly connected to the rotating shaft 18 to rotate. This drives the glass tube body 2 fixed on the carrying tray 21 to rotate. Then, the second valve 7 is opened and the electric fan 31 is started. The heat in the heat storage tank 5 is transferred to the heat transfer box 32 through the airflow generated by the electric fan 31 via the heat transfer pipe 33. Then, the heat from the heat transfer box 32 passes through the air outlet 29 and is blown by the electric fan 31 onto the surface of the rotating glass tube body 2 for preheating. Then, the gas heater 28 is started. The heat generated by the gas heater 28 is blown by the electric fan 31 onto the surface of the rotating glass tube body 2 for heating and annealing.

[0081] After the annealing process is completed, the intermediate sealing assembly is activated, causing the sealing door 10 to open upwards. Then, the material conveying assembly is activated to transport the annealed glass tube body 2 to the cooling assembly. The material conveying assembly is then closed, the sealing door 10 is closed, and the cooling fan 37 and the exhaust fan 40 are activated. The airflow generated by the cooling fan 37 and the exhaust fan 40 quickly carries the heat from the rotating glass tube body 2 through the exhaust hole 38 to the heat collection box 3. The first valve 6 is opened, and the heat rises from the exhaust pipe 4 and enters the heat storage tank 5 through the first valve 6. After the cooling process is completed, the first valve 6, the micro motor 16, the cooling fan 37, and the exhaust fan 40 are closed. The sealing door 10 near the drive motor 12 is opened, and the material conveying assembly is activated to transport the glass tube body 2 out of the furnace shell 1.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
