The technical scheme has the working principle and beneficial effects that: a second embodiment of the burner 2 is provided in this example. To further increase the accuracy of the combustion test, the sample is placed in a combustion bowl for combustion, thereby ensuring that the burning ash does not clog the air holes 24 and affect the test data.
In this embodiment, the fixing groove 25 is additionally formed in the inner bottom of the combustion furnace 2 for installing the combustion bowl fixer 6, the air holes 24 are circumferentially formed around the reinforcing groove 25, so that the air is prevented from entering the detection device 4, the magnetic attraction portions 65 are arranged on the fixing groove 25 and the inserting portion 64, the magnetic attraction portions 65 can be permanent magnets, the magnetic poles of the two magnetic attraction portions 65 are opposite, when the combustion bowl fixer 6 is installed, the inserting portion 64 is only required to be inserted into the fixing groove 25, the quick connection of the combustion bowl fixer 6 can be realized under the action of magnetic force, and the pin can play a limiting role on the combustion bowl fixer 6.
When the combustion bowl is placed, different clamping modes can be selected according to the shape of the combustion bowl, namely if the combustion bowl is a crucible with a collet, three chucks of the clamping part 63 can be outwards spread from the inside of the crucible collet, and the collet of the crucible can also be directly clamped from the outside, as shown in fig. 10.
Taking the bottom support of the crucible as an example, the handle on the side wall of the adjusting part 62 is rotated, so that the adjusting part 62 rotates by taking the bulge of the fixing part 61 as a rotating shaft, and along with the rotation of the adjusting part 62, the limiting block 69 on the top surface of the adjusting part slides in the sliding groove 68 at the bottom of the rotating head, so that the rotating head is driven to rotate by taking the shaft connecting end of the rotating head and the fixing part 61 as a shaft, the clamping part 63 is opened, and finally three chucks can fix the three chucks from the inner wall of the bottom support of the crucible. The friction block 67 positioned on the bottom surface of the adjusting part 62 can ensure that a large friction force exists between the adjusting part 62 and the fixing part 61, so that the clamping force of the clamping part 63 can be manually adjusted and cannot be reset under the action of the friction block 67, and further the clamping stability is ensured. The through holes can ensure the communication between the detecting device 4 and the inside of the combustion furnace 2, thereby ensuring the accuracy of the experiment.
