Accompanying drawing explanation
Fig. 1 is a kind of chemicals danger of combustion level estimate apparatus structure schematic diagram.
Embodiment
1 pair of the specific embodiment of the present invention is described further by reference to the accompanying drawings:
A kind of chemicals danger of combustion level estimate device, comprise rosette 4, rosette support 5 and pyroceram cover 6, circular hole is left in the middle of described rosette support 5, rosette 4 is fixedly mounted in the circular hole of rosette support 5, the bottom of metal dish support 4 is provided with applicator support 2, applicator support 2 is provided with heating arrangement 1, and heating arrangement 1 is connected with temperature controller; Described rosette is provided with thermopair 3, and thermopair 3 is connected with temperature reading devices; Described pyroceram cover 6 is buckled in above rosette 4.
The temperature of temperature controller setting is 816 DEG C, and when the temperature of rosette 4 is higher than 816 DEG C, temperature controller controls heater stop heating.
Rosette 4 is stainless steel disk, and the diameter of rosette 4 is 50mm, and the degree of depth is 12.7mm.Rosette support 5 adopts stupalith to make, and leave the circular hole of diameter 54mm in the middle of between metal, rosette 4 is fixedly mounted in circular hole.Applicator support 2 also adopts stupalith to make.Stupalith heat resisting temperature is higher than 816 DEG C.
Thermopair 3 adopts chromel-alumel thermocouple, and chromel-alumel thermocouple is welded on the central authorities of rosette 4.Temperature reading devices is temperature pot, accuracy ± 0.6 DEG C.
A kind of chemicals danger of combustion of the present invention level estimate device, also comprise ceramic thread, ceramic thread is wrapped on rosette, is firmly fixed on rosette support by rosette.
