[0052] In use, unlock the latch 32, open the device door 3 by pulling the door handle 31, and then fix both ends of the heat-insulating material to be tested that needs to be studied through the clamping member 92. The heat-insulating material is generally strip-shaped. Place the end of the heat-insulating material between the clamping plate 923 and the fixing block 922, and screw the nut 924 until it cannot be rotated further. Place the clamping members 92 on the base 91 one by one, and place a standard weight 71 on the heat-insulating material fixed by the two clamping members 92. Turn on the camera 6, and then push the fuel nozzle 82 of the flame spreader 8 under the heat-insulating material by pulling the handle 85. The left end of the fuel supply pipe 81 is connected to a fuel source (such as a gas cylinder). Turn on the ignition switch of the flame spreader 8, and ignite the heat-insulating material in all directions through the flame spreader 8. After ignition, turn off the ignition switch of the flame generator, and pull the fuel nozzle 82 of the flame spreader 8 to the left side (away from directly below the heat-insulating material). Finally, turn on the suction fan 53, the wind detector 52, and the smoke purifier 51. Study the influence of different wind forces on combustion through the wind detector 52, study the flexibility and support performance of different heat-insulating materials during combustion by placing standard weights 71 with different weights on the heat-insulating material, record the maximum combustion height of the heat-insulating material through the set scale 10, and record the entire combustion process of the heat-insulating material through the camera 6.
[0053] The driving member 86 can drive the injection cap 821 to rotate, and along the diameter direction away from the center of the upper surface of the injection cap 821, the diameter of the fuel injection port 825 gradually increases, ensuring that while the flame spreader 8 rotates and burns over a large area, the combustion intensity of the flames emitted from各处 of the injection cap 821 varies little, being closer to the actual situation of large-area combustion and avoiding the phenomenon of point combustion. For heat-insulating materials of different thicknesses, the slide rail 83 and the flame spreader 8 can be synchronously moved up and down through the lifting mechanism to adjust the distance between the injection cap 821 and the heat-insulating material to be appropriate.
