Embodiment 1
[0045] combine figure 1 , figure 2 and image 3 As shown, a device of the present invention that uses electrical signals to detect the assimilation temperature of iron ore powder includes a heating unit 100 and a detection unit 200, the heating unit 100 is used to heat the iron ore powder sample 400, and the heating unit 100 includes a heating furnace Furnace body 120 , the heating furnace body 120 is an electric heating furnace or a microwave heating furnace or other heating furnaces, of course, it can also be a fuel heating furnace.
[0046] The furnace body 120 of the heating furnace is provided with a support platform 110 , and the support platform 110 is used to carry a calcium oxide tablet 130 . The heating unit 100 is provided with a calcium oxide tablet 130 , and the calcium oxide tablet 130 is used to carry the iron ore powder sample 400 . The support platform 110 is located at the center of the furnace body 120 of the heating furnace. The heating unit 100 , the ...
Embodiment 2
[0082] Such as Figure 4 As shown, the basic content of this embodiment is the same as that of Embodiment 1, except that the first electrode 221 and the second electrode 222 are arranged in parallel, and the horizontal distance between the first electrode 221 and the second electrode 222 is d, where d≤ R / 2, the present embodiment takes d=R / 2, and R is the diameter of the accumulation surface of the iron ore powder sample 400 on the calcium oxide tablet 130 .
[0083] The first electrode 221 and the second electrode 222 run through the calcium oxide tablet 130, thereby improving the accuracy of detection, so that as long as the iron ore powder is assimilated in one place, the change of the electrical signal can be detected in time, thereby improving the detection accuracy. accuracy. In this embodiment, the thickness between the top of the electrode hole 131 and the upper surface of the calcium oxide sheet 130 is δ, and δ is 0.2-2mm. In this embodiment, δ=0.5mm.
Embodiment 3
[0085] Such as Figure 8 As shown, the basic content of this embodiment is the same as that of Embodiment 1, except that the first electrode 221 of this embodiment is placed in the calcium oxide pellet 130 , and the second electrode 222 is placed in the iron ore powder sample 400 . The detection unit 200 is located on the upper part of the iron ore powder sample 400, and the detection unit 200 is located directly above the first electrode 221, and the temperature measurement end 211 of the detection unit 200 is close to the iron ore powder sample 400, so that the temperature measurement end 211 can promptly and quickly detect the temperature when the assimilation reaction of iron ore powder occurs, and improve the accuracy of detection.
