[0031] The method of using the iron ore high temperature load reduction soft melting dripping device, the specific operating steps are as follows:

[0032] A: Connect the device to an external power supply and controller, control the vibration motor 34 to drive the screening mesh plate 33 to vibrate, and the personnel pour the iron ore material to be tested onto the screening mesh plate 33 in the storage box 9. The vibrating screening mesh plate 33 screens the material, and the iron ore that meets the screening mesh holes falls to the bottom of the storage box 9 for storage. The material with a volume larger than the mesh hole moves to the left under the action of gravity, and finally falls into the collection box 21 through the discharge shell 20 for collection. This can ensure that the volume of the experimental material is uniform and improve the experimental effect. When it is necessary to add material to the high-temperature furnace body 6, control the feeding motor 38 to drive the feeding screw 36 to rotate forward, and the forward-rotating feeding screw 36 transports the material that falls into the feeding barrel 37 forward, and finally discharges it through the discharge pipe 35 and falls into the high-temperature furnace body 6. This has the function of automatic feeding and can accurately control the feed amount;

[0033] B: After the iron ore sample for testing is put into the high-temperature furnace body 6, the high-temperature furnace body 6 is started and the temperature of the high-temperature furnace body 6 is controlled to rise. When the high-temperature furnace body 6 is heated to 1350°C, the iron ore gradually softens and drips. Under the pressure and gravity of the load weight 10, the displacement sensors 14 on both sides drive the quartz reaction rod 13 to move downward through the connection top plate 12 to squeeze the internal softened iron ore. The iron ore gradually softens and deforms. The degree of softening is measured by the displacement sensor 14. The physical performance state of the equipment is directly observed by the high-temperature resistant visual window 5. As the temperature continues to rise, molten iron drips. The dripping molten iron drips into the quartz sample dish 3 through the silicon carbide reactor 28. In this way, the internal reaction is visualized and the internal sample state can be directly observed, which is more intuitive.

[0034] C: In the process of dripping into the quartz sample dish 3, odorous gas will be generated. At this time, the exhaust fan 18 is controlled to work to draw the odorous gas into the purification shell 39. The internal activated carbon adsorption mesh plate 22 can adsorb and purify the odorous gas to avoid pollution of the experimental environment. After dripping, the transmission motor 23 is controlled to work to drive the driving screw 27 to rotate forward. The forward rotating driving screw 27 makes the movable slider 24 with a threaded sleeve on the surface move forward, and the quartz sample dish 3 connected to the top of the bottom plate 25 moves forward and away from the silicon carbide reactor 28. After moving to the front, the personnel removes the quartz sample dish 3. In this way, there is no need for personnel to take and place the quartz sample dish 3 under the silicon carbide reactor 28, and the operation is safer and simpler.

[0035] In summary: the iron ore high-temperature load reduction soft melting dripping device, through the coordinated use of the quartz sample dish 3, the conveying mechanism 4, the high-temperature resistant visual window 5, the high-temperature furnace body 6, the upper fixed plate 7, the mounting vertical plate 8, the storage box 9, the load weight 10, the measuring mechanism 17, the exhaust fan 18 and the activated carbon adsorption mesh plate 22, solves the problems of being unable to directly observe the internal sample state, unable to ensure the uniform volume of the experimental material, affecting the detection experiment effect, and unable to automatically load the material.
