Description

Technical Field

[0001] This utility model relates to the field of tempering furnace technology, specifically a glass tempering furnace. Background Technology

[0002] A glass tempering furnace is a heating device that can heat and soften ordinary glass. Once the glass is softened, it quickly dissipates heat, thereby generating uniform internal stress in the glass and improving its bending and impact resistance.

[0003] Chinese patent document CN218620617U discloses a glass tempering furnace, including a frame. The furnace body is mounted on one side of the top of the frame, and a cover is mounted on the other side. A roller conveyor belt is bolted into the cover, with the top of the rollers of the conveyor belt higher than the cover. An electric heating element is bolted to the bottom of the cover. First electric cylinders are bolted to both sides of the cover. This glass tempering furnace, with its frame and cover forming a sealed space under the action of the first electric cylinders, encloses the roller conveyor belt. The electric heating element is located within this space, allowing for rapid temperature increase of the roller conveyor belt during operation. This preheating process reduces the time required to heat the glass to a softened state, improving production efficiency and making it suitable for widespread application.

[0004] The glass tempering furnaces in the prior art are not equipped with convenient safety pressure relief and exhaust devices, which leads to excessive internal air pressure and safety accidents. At the same time, their heat insulation and protection effects are poor, which can easily cause overheating on the outside of the furnace. Therefore, it is necessary to develop a new type of glass tempering furnace. Utility Model Content

[0007] Preferably, the high-temperature resistant coating shell is disposed on the outer surface of the glass fiber insulation interlayer, and the alloy inner liner structure is disposed on the inner surface of the glass fiber insulation interlayer.

[0008] Preferably, four pressure relief exhaust pipes are provided, and a sealing structure is provided at the connection between the pressure relief exhaust pipes and the main body of the tempering furnace.

[0009] Preferably, one end of the exhaust switch valve is provided with an exhaust slot.

[0010] Preferably, a sealed furnace door is provided on the front surface of the tempering furnace body, and the sealed furnace door is movably connected to the tempering furnace body through a hinge mechanism.

[0011] Preferably, a protective frame is welded and fixed to the outside of the tempering furnace body, and casters are installed at the bottom of the protective frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model provides a convenient and secure pressure relief and exhaust device at the top of the tempering furnace, which can safely and stably discharge the high-temperature gas generated inside the furnace, preventing excessive internal pressure from causing safety accidents. At the same time, it provides high-temperature resistant and heat-insulating protection for the furnace shell by installing a high-temperature resistant coated outer shell and a fiberglass heat insulation layer inside the furnace body, preventing internal heat from diffusing to the outside of the furnace body and causing overheating.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1-4 An embodiment of this utility model provides a glass tempering furnace, including a tempering furnace body 2. A fixing frame 11 is installed on the top of the tempering furnace body 2. A pressure relief exhaust pipe 10 is installed on the fixing frame 11. One end of the pressure relief exhaust pipe 10 is sealed and connected to the interior of the tempering furnace body 2. The other end of the pressure relief exhaust pipe 10 is provided with a sealing joint 9. The sealing joint 9 is screwed to an exhaust branch pipe 12 through a spiral seal. One end of the exhaust branch pipe 12 is sealed and connected to an exhaust main pipe 6 through a bend joint 7. A pressure monitoring gauge 8 and an exhaust switch valve 5 are respectively installed on the exhaust main pipe 6. The tempering furnace body 2 includes a high-temperature resistant coated outer shell 15, a glass fiber heat insulation interlayer 16, and an alloy inner liner structure 17.

[0021] Furthermore, the high-temperature resistant coating shell 15 is disposed on the outer surface of the glass fiber insulation interlayer 16, and the alloy inner liner structure 17 is disposed on the inner surface of the glass fiber insulation interlayer 16. By providing the high-temperature resistant coating shell 15, a good high-temperature protection effect can be achieved, and the glass fiber insulation interlayer 16 can effectively prevent the high-temperature heat inside the furnace from dissipating and being transferred to the outside of the furnace.

[0022] Furthermore, there are four pressure relief exhaust pipes 10. A sealing structure is provided at the connection between the pressure relief exhaust pipe 10 and the tempering furnace body 2. The sealing structure provides a good sealing protection effect. The pressure relief exhaust pipe 10 can be used to discharge the high-temperature gas generated inside the tempering furnace body 2.

[0023] Furthermore, one end of the exhaust switch valve 5 is provided with an exhaust port 4 for discharging gas.

[0024] Furthermore, a sealing furnace door 13 is provided on the front surface of the tempering furnace body 2. The sealing furnace door 13 is movably connected to the tempering furnace body 2 through a hinge mechanism 14, which facilitates the sealing operation of the tempering furnace body 2.

[0025] Furthermore, a protective frame 3 is welded and fixed to the outside of the tempering furnace body 2, and casters 1 are installed at the bottom of the protective frame 3 to facilitate safe and stable bearing and flexible transfer of the tempering furnace body 2.

[0026] Working principle: During use, a fixed frame 11 is installed on the top of the tempering furnace body 2. A pressure relief exhaust pipe 10 is installed on the fixed frame 11. One end of the pressure relief exhaust pipe 10 is sealed and connected to the interior of the tempering furnace body 2. The other end of the pressure relief exhaust pipe 10 is equipped with a sealing joint 9. The sealing joint 9 is screwed to an exhaust branch pipe 12 through a spiral seal. One end of the exhaust branch pipe 12 is sealed and connected to the exhaust main pipe 6 through a bend joint 7. By installing the pressure relief exhaust pipe 10 above the tempering furnace body 2 and opening the exhaust switch valve 5, the high-temperature gas generated inside the tempering furnace body 2 can be quickly discharged from the pressure relief exhaust pipe 10. The exhaust pipes 10 are interconnected and sealed by exhaust branch pipes 12, with tight and stable connection and good sealing performance. This allows the high-temperature gas generated inside the tempering furnace body 2 to be safely and stably discharged, preventing excessive gas pressure inside the tempering furnace body 2 from causing safety accidents. The tempering furnace body 2 includes a high-temperature resistant coated outer shell 15, a fiberglass insulation interlayer 16, and an alloy inner liner structure 17. The high-temperature resistant coated outer shell 15 provides good high-temperature protection, and the fiberglass insulation interlayer 16 effectively prevents the high-temperature heat inside the furnace from dissipating and transferring to the outside of the furnace, thus providing good safety protection for the tempering furnace body 2.
