Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 5 As shown, a sintering furnace for real-time temperature monitoring of asbestos short rollers comprises: a furnace body 5, a control cabinet 4 and a movable furnace door 1.

[0028] The inner wall of the furnace body 5 is fixedly connected with a heating wire 6, the top of the furnace body 5 is fixedly connected with a thermocouple 7, the side end of the furnace body 5 is fixedly connected with a terminal block 16, the terminal block 16 is fixedly connected to the thermocouple 7, the control cabinet 4 is arranged at the side end of the furnace body 5, the control cabinet 4 cooperates with the thermocouple 7, the control cabinet 4 is fixedly connected to the heating wire 6, the movable furnace door 1 is slidably connected to the inner wall of the furnace body 5, and a plurality of connecting shafts 12 are provided inside the movable furnace door 1. The side end of the connecting shaft 12 is fixedly connected with a three-jaw chuck 14, and a plurality of asbestos short roll blanks are clamped by the three-jaw chuck 14. The movable furnace door 1 provides support and fixation for the three-jaw chuck 14 through the connecting shaft 12. The asbestos short roll compact is placed in the furnace body 5, and the heating wire 6 fixed in the furnace body 5 is running. The heating wire 6 heats the asbestos short roll compact for firing. When the asbestos short roll compact is in the process of firing, the thermocouple 7 detects the temperature in the furnace body 5, and the thermocouple 7 transmits the real-time temperature in the furnace body 5 to the tooth plate 10 for display. When the real-time temperature in the furnace body 5 is lower than the appropriate firing temperature of the asbestos short roll compact, the staff controls the tooth plate 10 to increase the power of the heating wire 6, thereby ensuring that the temperature in the furnace body 5 rises, ensuring that the asbestos short roll compact is at a suitable firing temperature, thereby ensuring the firing quality of the asbestos short roll compact;

[0029] It should be noted that when the asbestos short roller compact is being fired, the side end of the movable furnace door 1 is fitted against the inner wall of the furnace body 5, and the tooth plate 10 can control the power of the heating wire 6 through the terminal block 16. The current is connected to the heating wire 6 through the terminal block 16, thereby providing electrical energy for the heating wire 6. The heating wire 6 is distributed around the inner wall of the furnace body 5, which can ensure that the asbestos short roller compact can be heated by the heating wire 6 on all sides, thereby achieving uniform heating of the asbestos short roller compact and ensuring the quality of firing of the asbestos short roller compact.

[0030] In some specific embodiments, a high-temperature sealing cotton 15 is fixedly connected to one end of the movable furnace door 1 close to the furnace body 5. A circular hole is opened in the high-temperature sealing cotton 15 parallel to the axis of the three-jaw chuck 14, and the high-temperature sealing cotton 15 is slidably connected to the inner wall of the furnace body 5. When the movable furnace door 1 and the inner wall of the furnace body 5 are in contact, the high-temperature sealing cotton 15 fixed on the side end of the movable furnace door 1 blocks the opening of the furnace body 5 to prevent heat from flowing out of the furnace body 5, thereby achieving sealing of the furnace body 5. When the asbestos short roller blank is installed on the three-jaw chuck 14, the asbestos short roller blank passes through the circular hole, and the inner diameter of the circular hole is larger than the diameter of the asbestos short roller blank.

[0031] In some specific embodiments, a plurality of connecting shafts 12 are equidistantly distributed along the width and height directions of the movable furnace door 1, a driven chain 13 is sleeved and connected between the plurality of connecting shafts 12, and both ends of the driven chain 13 are respectively meshed with the connecting shafts 12, a rotating drive machine 11 is fixedly connected to the side end of the movable furnace door 1, and a rotating shaft 17 is fixedly connected to the end of the rotating drive machine 11 close to the connecting shaft 12, and a driving chain 18 is sleeved between the rotating shaft 17 and the connecting shaft 12, and both ends of the driving chain 18 are respectively meshed with the rotating shaft 17 and the connecting shaft 12. Tooth connection, in order to further ensure that the asbestos short roller blank is heated evenly, when the asbestos short roller blank is fired, the rotary drive motor 11 runs, and the rotary drive motor 11 drives the rotary shaft 17 to rotate, and the rotary shaft 17 drives the connecting shaft 12 to rotate through the drive chain 18, and the connecting shaft 12 drives several connecting shafts 12 to rotate through the driven chain 13, so that the connecting shaft 12 drives the asbestos short roller blank to rotate through the three-jaw chuck 14, and the rotating asbestos short roller blank can be heated more evenly, thereby ensuring the firing quality of the asbestos short roller blank.

[0032] In some specific embodiments, the bottom end of the furnace body 5 is fixedly connected with a tooth plate 10, the tooth plate 10 is located at the bottom of the movable furnace door 1, the tooth plate 10 is meshingly connected with a movable shaft 9, the side end of the movable shaft 9 is fixedly connected with a movable driving machine 8, the movable driving machine 8 is fixedly connected to the bottom end of the movable furnace door 1, the bottom end of the movable furnace door 1 is fixedly connected with a load-bearing roller 3, the two ends of the load-bearing roller 3 are respectively connected with a guide rail 2 in a rolling manner, and the guide rail 2 is fixedly connected to the inner wall of the furnace body 5. Before the asbestos short roller compact is fired in the furnace body 5, after the asbestos short roller compact is installed on the three-jaw chuck 14, the mobile driving machine 8 is operated, and the mobile driving machine 8 drives the movable shaft 9 to rotate, and the movable shaft 9 drives the movable shaft 9 to rotate by meshing with the tooth plate 10. The movable driving machine 8 moves, and the movable driving machine 8 drives the movable furnace door 1 to move. The movable furnace door 1 rolls along the guide rail 2 through the carrying roller 3, thereby realizing the effect that the movable furnace door 1 can move automatically. The movable furnace door 1 moves into the furnace body 5, and the movable furnace door 1 transports the carried asbestos short roller compact into the furnace body 5 through the connecting shaft 12 and the three-jaw chuck 14.
