[0030] Reference Figure 1-5 The utility model provides an embodiment: a combustion-supporting air delivery pipeline structure, including a bellows 1, the left end of the bellows 1 is fixedly connected to a combustion-supporting air main pipe 2, the right end of the bellows 1 is fixedly connected to a combustion-supporting fan 3, the left end of the combustion-supporting air main pipe 2 is fixedly connected to a connecting pipe 6, the outer wall of the connecting pipe 6 is provided with an electric control valve 7, the top of the combustion-supporting air main pipe 2 is fixedly connected to an air exhaust port 4, the top of the bellows 1 is fixedly connected to an air supply port 5, and the connecting pipe 6, the air supply port 5 and the inner wall of the bellows 1 are all fixedly connected to a thermometer 8.

[0031] Specifically, the combustion-supporting fan 3 is started to suck air into the combustion-supporting air main duct 2 through the exhaust port 4. The air inside the combustion-supporting air main duct 2 is heated by the bellows 1 and then sent into the kiln from the combustion-supporting fan 3. A thermometer 8 is added to the middle position of the combustion-supporting air main duct 2, the bellows 1 and the air supply port 5. The thermometer 8 detects the temperature inside the device and then adjusts the opening of the electric control valve 7 in time according to the readings of the three thermometers 8, so as to achieve the purpose of stabilizing the combustion-supporting air temperature.

[0032] Among them, the fixed box 9 fixedly connected at the left end of the connecting pipe 6 is connected to a fixed plate 14, and the bottom end of the fixed plate 14 is fixedly connected to a connecting frame 15, and the inner wall of the connecting frame 15 is provided with a fixed groove 18, and the inner wall of the fixed groove 18 is slidably connected with a filter screen 19. Among them, the fixed frames 10 fixedly connected on both sides of the outer wall of the fixed box 9, the inner wall of the fixed frame 10 is slidably connected with a pull rod 11, and the outer wall of the pull rod 11 is fixedly connected to a limiting plate 12, and a spring 13 is provided between the limiting plate 12 and the fixed frame 10, and the inner wall of the fixed plate 14 is provided with a plurality of fixing holes 16 corresponding to the pull rod 11, and the top end of the fixed plate 14 is fixedly connected with a handle 17, the outer wall of the fixed plate 14 is slidably connected to the inner wall of the fixed box 9, and the outer wall of the connecting frame 15 is slidably connected to the inner wall of the fixed box 9, one end of the spring 13 is connected to the limiting plate 12, and the other end of the spring 13 is evenly connected to the fixed frame 10, and the outer wall of the limiting plate 12 is slidably connected to the inner wall of the fixed frame 10.

[0033] Specifically, the filter 19 can filter impurities and particulate matter in the air and protect the internal equipment of the kiln from damage. When the filter 19 needs to be disassembled and replaced, the pull rod 11 is pulled to disengage it from the inside of the fixing hole 16, and then the handle 17 is pulled to drive the fixing plate 14 to move. When the fixing plate 14 moves, it drives the connecting frame 15 to slide out of the fixing box 9, and then the filter 19 is pushed to disengage it from the connecting frame 15. When installing, the filter 19 is pushed into the connecting frame 15. The fixing groove 18 inside the connecting frame 15 will block the filter 19 to prevent it from detaching, and then the connecting frame 15 is inserted into the fixing box 9. At this time, the pull rod 11 is released and the spring 13 will bounce the limit plate 12.

The air inside the combustion-supporting air main pipe 2 will be heated by the bellows 1 and then sent into the kiln from the combustion-supporting fan 3. A thermometer 8 is added to the middle position of the combustion-supporting air main pipe 2, the bellows 1 and the air supply port 5. The thermometer 8 will detect the temperature inside the device, and then adjust the opening of the electric control valve 7 in time according to the readings of the three thermometers 8, so as to achieve the purpose of stabilizing the combustion-supporting air temperature. The filter 19 can filter impurities and particulate matter in the air to protect the internal equipment of the kiln from damage. When the filter 19 needs to be disassembled and replaced, it can be removed by pulling the pull rod 11 to disengage it from the interior of the fixing hole 16, and then pull the handle 17 to drive the fixing plate 14 to move, and when the fixing plate 14 moves, it drives the connecting frame 15 to slide out of the interior of the fixing box 9, and then pushes the filter 19 to disengage it from the connecting frame 15. During installation, the filter 19 is pushed into the connecting frame 15, and the fixing groove 18 inside the connecting frame 15 will block the filter 19 to prevent it from disengaging, and then the connecting frame 15 is inserted into the fixing box 9. At this time, the pull rod 11 is released and the spring 13 will bounce the limit plate 12. When the limit plate 12 is bounced, it drives the pull rod 11 to be inserted into the fixing hole 16 for fixation, thereby facilitating the replacement of the filter 19.
