[0047] Working principle: in use, different kinds of coal blocks that need to be detected are selected, the number of coal blocks is less than or equal to four, and then the weight of the coal blocks is controlled to be consistent, and sample preparation is completed;

[0048] Then the rotating motor 505 is started, the first screw rod 504 is driven to rotate, the connecting frame 503 is driven to move downward, the supporting plate 501 is moved downward to the lower side of the processing cylinder 1, then each coal block is ignited and put into each spherical shell 5071, and the placement positions of different kinds of coal blocks need to be clear during placement;

[0049] Then the motor 505 drives the supporting plate 501 to move back until the top sealing plate 5073 at the top of the four spherical shells 5071 is in close contact with the bottom sealing plate 404 at the bottom of the spherical shell cylinder 403 above the corresponding position, and the top end of the fixed cylinder 401 is connected with one end of the connecting pipe 3, so that the four flue gas detection pipes 2 can communicate with the inner cavities of the corresponding spherical shells 5071, and then the fan on the flue gas detection pipe 2 is opened to drive the air below the processing cylinder 1 to enter the spherical shell 5071 through the air inlet hole 5072 on the spherical shell 5071, and the flue gas generated by the burning of the coal blocks enters the inside of the fixed cylinder 401, and then passes through the connecting pipe 3 into the flue gas detection pipe 2, and the smoke monitoring instrument in the flue gas detection pipe 2 detects the smoke concentration, the platinum resistance measures the flue gas temperature, the pitot tube measures the flue gas flow rate, and the capacitive sensor measures the flue gas humidity;

[0050] Wherein, since the spherical shell 5071 is arranged in a spherical shell shape, the air inlet holes 5072 are uniformly arranged on the air inlet holes 5072, so that the air can uniformly contact the coal blocks from the air inlet holes 5072, improving the uniformity of the coal block combustion, and the driving motor 412 is opened to drive the gear 411 to rotate, and the gear 411 is engaged with the gear ring 410 on the outside of the rotating ring 408, thereby driving the rotating ring 408 to rotate, so that the pressing block 409 passes through each pressure receiving block 407 on the top plate 405, and can push the spherical shell cylinder 403 to rotate and tilt, and the bottom sealing plate 404 at the bottom of the spherical shell cylinder 403 is in close contact with the top sealing plate 5073 at the top of the spherical shell 5071, so that the rotation and tilting of the spherical shell cylinder 403 drives the spherical shell 5071 to rotate and tilt, and the rotation direction is constantly changed, so that the coal blocks constantly roll inside the spherical shell 5071, so that each position on the outer surface of the coal blocks can contact and burn with the air, improving the uniformity of the coal block combustion, and after the coal block combustion is completed, the coal block combustion residues are left in the spherical shell 5071;

[0051] During the swinging of the spherical shell 5071, the two limiting rings 5083 in the placing groove 506 limit the spherical shell 5071, and after the coal block combustion is completed, the top motor 50813 is opened to drive the second screw 50812 to rotate, thereby driving the movable plate 50810 to move downward, and then the moving block 5086 is pushed by each second connecting rod 50811 to move toward one side of the longitudinal guide frame 5082, and then the upper and lower guide plates 5084 are pushed by the first connecting rod 5087 to move away from each other along the longitudinal guide frame 5082, so that the two limiting rings 5083 move away from each other, so that the limiting of the two limiting rings 5083 on the spherical shell 5071 is released, and at this time the spherical shell 5071 moves downward under the action of gravity, so that the pressure of the supporting spring 5075 on the pressure sensor 5076 increases, and the weight of the coal block combustion residues in the spherical shell 5071 is measured by the pressure sensor 5076;

[0052] During the detection process, the air temperature and humidity in the spherical shell 5071 are the same, so that different types of coal blocks can be burned in the same air environment, facilitating the measurement of the flue gas of the coal block combustion under the same condition, and facilitating the comparison of the combustion detection of different types of coal blocks.
