Embodiment 1

[0024] Reference attached figure 1 , a thermogravimetric analysis furnace, comprising a furnace 5 and an electronic analytical balance 6, the furnace 5 is provided with a refractory container 1 for containing samples to be analyzed, and the thermogravimetric analysis furnace also includes a support frame connecting the refractory container 1 and the electronic analytical balance 6 4. The supporting frame 4 is an integrated structure, including the connecting part 401 and the supporting part 402, whose dimensions increase sequentially from top to bottom to form a tapered shape, and inside there is a cavity that increases in size from top to bottom.

[0025] In this embodiment, the bottom of the refractory container 1 has an outwardly protruding bump 7 , and the upper end opening of the connecting portion 401 is used to accommodate the bump 7 .

[0026] In this embodiment, a flashboard 3 is also included, and the support frame 4 has two sockets on its wall outside the furnace 5....

Embodiment 2

[0028] Reference attached figure 2 , the support frame 4 is an integrated structure, the support frame 4 is provided with a partition 10 to divide the support frame 4 into a connecting part 401 and a supporting part 402, the connecting part 401 is a cylindrical structure, and the connecting part 401 has a cylindrical cavity inside, and The diameter of the cylindrical cavity is consistent from top to bottom, and the size of the support part 402 increases sequentially from top to bottom to form a frustum shape, and the support part 402 is a hollow structure.

[0029] In this embodiment, a protective sleeve 9 is provided between the connecting portion 401 and the furnace 5 , and the protective sleeve 9 is fixed on the furnace shell 8 to prevent sundries from falling to the electronic analytical balance 6 .

[0030] Other unmentioned structure is with embodiment 1.

Abstract

The invention provides a thermogravimetric analysis furnace capable of supporting large-mass samples. The thermogravimetric analysis furnace is firm in supporting and simple in structure, and comprises a hearth and an electronic analytical balance, and a fireproof container used for containing the samples to be analyzed is arranged in the hearth. The thermogravimetric analysis furnace further comprises a supporting frame connected with the fireproof container and the electronic analytical balance, the supporting frame comprises a connecting portion and a supporting portion, the upper portion of the connecting portion is connected with the bottom of the fireproof container in a convex-concave inserted mode, the lower portion of the connecting portion is connected with the upper portion of the supporting portion, the size of the supporting portion is sequentially increased from top to bottom, and the supporting portion is in a platform cone shape.

Description

technical field [0001] The invention relates to a thermogravimetric analysis furnace. Background technique [0002] At present, thermogravimetric analysis is basically performed on small-mass samples. Because the quality of the sample is usually less than the order of grams, the volume and weight of the crucible used are very small, so the support structure of the sample is a single-rod mode of a refractory support rod, and the platinum-rhodium metal bracket is fixed on the support rod to support the crucible and the sample. weight. Due to the small sampling and the fact that the actual samples are usually uneven, the results of thermogravimetric analysis cannot reflect the actual characteristics of industrial raw materials or ingredients well, which has a negative impact on industrial applications. Increasing the sample weight for thermogravimetric analysis can better solve this problem. However, when the weight of the sample increases, the traditional thermogravimetric ...
