[0026] Example 1
[0027] Referring to Figures 1-5, the first embodiment of this utility model provides a glass tempering furnace with adjustable heating temperature, including a base plate 1, a clamping seat 14 slidably connected to the upper surface of the base plate 1, a furnace chamber 3 fixedly installed on the top of the base plate 1, a heat outlet box 9 fixedly installed on the inner wall of the furnace chamber 3, a hot air blower 5 fixedly installed on the top of the furnace chamber 3, a heat transfer pipe 10 connected to the outer surface of the hot air blower 5, and the end of the heat transfer pipe 10 away from the hot air blower 5 connected to the outer surface of the heat outlet box 9. When the hot air blower 5 is started, hot air is delivered to the heat outlet box 9 through the heat transfer pipe 10 and sprayed out to heat the glass. An air outlet box 8 is fixedly installed on the inner wall of the furnace chamber 3.
[0028] The outer surface of the air outlet box 8 is connected to the air outlet pipe 2. The end of the air outlet pipe 2 away from the air outlet box 8 is connected to the bag filter 6. The inner wall of the furnace chamber 3 is fixedly installed with the air inlet box 7. The outer surface of the air inlet box 7 is connected to the air inlet pipe. The end of the air inlet pipe away from the air inlet box 7 is connected to the outer surface of the bag filter 6. The hot air ejected from the heat outlet box 9 and the dust it carries are sent into the bag filter 6 through the air inlet box 7. The bag filter 6 filters the dust and then sends the purified air to the air outlet box 8 through the air outlet pipe 2 to be ejected, further improving the heating effect of the heat outlet box 9 on the glass.
[0029] Example 2
[0030] Referring to Figures 1-5, this is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: an adjustment groove 1 is provided on the upper surface of the base plate 1, and a threaded rod 21 is rotatably connected to the inner wall of the adjustment groove 1. A servo motor for driving the threaded rod 21 to rotate is fixedly installed on the outer surface of the base plate 1. A threaded block 20 is threadedly installed on the outer wall of the threaded rod 21. The top of the threaded block 20 is fixedly connected to the bottom of the clamping seat 14. When the servo motor is started, the threaded rod 21 is rotated, which drives the threaded block 20 to move, thereby driving the clamping seat 14 to move and send the glass into the furnace chamber 3. An adjustment groove 2 is provided on the upper surface of the base plate 1, and a slide rod 19 is fixedly connected to the inner wall of the adjustment groove 2. A slider 18 is slidably connected to the outer wall of the slide rod 19. The top of the slider 18 is fixedly connected to the bottom of another clamping seat 14.
[0031] A threaded tube 15 is fixedly connected to the outer wall of the clamping seat 14. An adjusting rod 16 is threadedly connected to the inner wall of the threaded tube 15. A fixing plate 17 is rotatably connected to the outer wall of the adjusting rod 16. The glass is placed on the clamping seat 14, and then the knob is turned to drive the adjusting rod 16 to rotate, which drives the fixing plate 17 to move downward to clamp and fix the glass. A knob is fixedly connected to the end of the adjusting rod 16 away from the threaded tube 15. Several rubber blocks are fixedly connected to the outer wall of the fixing plate 17. A connecting plate 12 is fixedly connected between the two clamping seats 14. A cold air box 13 is fixedly installed on the inner wall of the furnace 3. A cooling pipe 11 is connected to the outer wall of the cold air box 13. A cold air fan 4 is fixedly installed on the top of the furnace 3. The end of the cooling pipe 11 away from the cold air box 13 is connected to the outer surface of the cold air fan 4.
[0032] The remaining structure is the same as that in Example 1.
[0033] During use, before heating the glass, the glass is first placed on the clamping seat 14. Then, the knob is turned to drive the adjusting rod 16 to rotate, which drives the fixing plate 17 to move downward to clamp and fix the glass. The servo motor is started to drive the threaded rod 21 to rotate, which drives the threaded block 20 to move, thereby driving the clamping seat 14 to move and send the glass into the furnace chamber 3. The hot air blower 5 is started to deliver hot air through the heat transfer pipe 10 to the heat outlet box 9 to spray out and heat the glass. The heat outlet box 9 is designed with multiple air channels to directionally impact the glass surface with high-speed hot air to ensure that dust is removed.
[0034] While heating the glass, the hot air ejected from the heat outlet box 9 carries away the dust adhering to the glass surface. Thermocouple sensors are installed inside the furnace chamber 3 and are evenly distributed on the inner wall of the furnace chamber 3 and at the air outlet of the heat outlet box 9 to monitor the temperature of the glass surface and airflow in real time. A PLC controller is installed outside the equipment. The thermocouple sensors convert the temperature signal into an electrical signal and transmit it to the PLC controller to dynamically adjust the heating power of the hot air blower 5 and the cooling rate of the cold air blower 4. During the heating stage, only the hot air blower 5 is started, and during the cooling stage, the hot air blower 5 is turned off and the cold air blower 4 is started.
[0035] During use, the bag filter 6 is activated. The bag filter 6 is made of high-temperature resistant Nomex fiber. The hot air ejected from the heat outlet box 9 and the dust it carries are sent into the bag filter 6 through the air inlet box 7. After the bag filter 6 filters the dust, the purified air is sent to the air outlet box 8 through the air outlet pipe 2 and ejected, which further improves the heating effect of the heat outlet box 9 on the glass and realizes simultaneous heating and dust removal. The clamping seat 14 continues to move, carrying the glass to the cold air box 13. The cold air fan 4 is activated to send cold air to the cold air box 13 through the cold air supply pipe 11 to cool the glass. The glass surface quickly solidifies to form a compressive stress layer, and the interior generates tensile stress due to slow cooling. This stress distribution increases the strength of the glass by 4-5 times and makes it break into safe small particles when broken.
[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
