Abstract
Description
Technical Field

[0002] Thermal explosion is an important metallurgical property of iron ore. It mainly occurs in natural iron ore. Ores with high thermal explosion index will lead to an increase in the amount of dust blown out during blast furnace smelting and deterioration of blast furnace operating indicators. The proportion of this kind of ore in the charge should be controlled, so it is very important in the smooth operation of the blast furnace. At present, the thermal explosion test is to weigh 5 portions of 500g of lump ore and place them in the experimental box, place the experimental box on the molybdenum plate, place the molybdenum plate at the end of the fork handle of the forklift, and use the forklift to send the molybdenum plate into the muffle furnace for the experiment. Close the muffle furnace door and wait for 30 minutes, then open the cabinet door, use a forklift to take out the molybdenum plate, let it stand and cool, and then screen it separately. This will lead to the following disadvantages: the temperature of the muffle furnace is high, and the experimenter is easily burned by high temperature when opening and closing the furnace door; the temperature of the experimental box and molybdenum plate that have just completed the experiment is extremely high, but the experimenter is close to the molybdenum plate when closing the cabinet door, and is more likely to be burned; finally, manual screening, the lump ore is extremely dusty after hot explosion, which is harmful to the respiratory system of the experimenter.

A cleaning sieve door is also arranged on the side wall of the fully automatic screening machine below the 0.5mm sieve door.
10. A fully automatic thermal burst test method, used in the fully automatic thermal burst test system as claimed in claims 1 to 9, characterized in that: The fully automatic thermal burst test method comprises: Take out several portions of ore and put them into the experimental boxes respectively placed on the loading platforms, place the loading platforms on the loading forks, and the locking mechanism on the loading platforms locks the loading platforms and the loading forks; The telescopic gas rods on both sides of the loading trolley wheels fix the loading trolley on the trolley placement platform; the driving mechanism drives the track to drive the trolley placement platform to move toward the oven; When it moves to the first lifting mechanism, the driving mechanism stops, the first lifting guillotine of the first lifting mechanism descends through the first winch and the first lifting rope, the first lifting guillotine hooks the guillotine hanging ring on the loading trolley, the telescopic gas rods on both sides of the wheels of the loading trolley retract, the first lifting guillotine lifts the loading trolley upward, the first infrared detector on the first ascending track detects the height of the loading trolley, and when the lifting guillotine is lifted to the first limit mechanism, the loading trolley faces the furnace inlet of the oven; After the screw rod ascending mechanism and the transverse screw rod movable mechanism are fine-tuned, the loading platform is sent into the oven; After drying is completed, the screw rod ascending mechanism and the transverse screw rod movable mechanism take the loading platform out of the oven. After taking it out, the first lifting and hoisting guillotine of the first lifting mechanism descends through the first winch and the first hoisting rope, and the loading trolley returns to the trolley placement platform. At this time, the telescopic mechanism extends to fix the trolley on the wheel track; The driving mechanism drives the trolley placement platform forward to the front of the muffle furnace, the second lifting guillotine of the second lifting mechanism descends through the second winch and the second lifting rope, the second lifting guillotine hooks the guillotine hanging ring on the loading trolley, the telescopic gas rods on both sides of the wheels of the loading trolley retract, the second lifting guillotine lifts the loading trolley upward, the second infrared detector on the second ascending track detects the height of the loading trolley, and when the lifting guillotine is lifted to the second limit mechanism, the loading trolley is facing the inlet of the muffle furnace; After the screw rod ascending mechanism and the transverse screw rod movable mechanism are fine-tuned, the loading platform is sent into the muffle furnace for thermal bursting experiment; After the thermal burst test is completed, the screw rod lifting mechanism and the transverse screw rod movable mechanism take the loading platform out of the muffle furnace. After taking it out, the second lifting and hoisting guillotine of the second lifting mechanism is lowered through the second winch and the second hoisting rope, and the loading trolley returns to the trolley placement platform. At this time, the telescopic mechanism extends to fix the trolley on the wheel track; The loading trolley is stationary and cooled on the track. When the ore in the experimental box on the loading platform has finished cooling, the driving mechanism continues to drive and moves the trolley placement platform to just below the third lifting mechanism. The third lifting and hoisting guillotine of the third lifting mechanism descends through the third winch and the third hoisting rope. The third lifting and hoisting guillotine hooks the trolley handle on the loading trolley, and the telescopic gas rods on both sides of the wheels of the loading trolley retract. The third hoisting guillotine lifts the loading trolley upward and pours the ore in the experimental box that has undergone thermal explosion into the fully automatic screening device.
