The hazardous waste slag plasma incinerator according to claim 1, wherein: the central shaft, the two racks, the worm wheel, the worm and the differential device are all made of high-temperature resistant materials; and when the fixed cone exceeds a third set temperature, the fixed cone begins to expand, and the first set temperature, the second set temperature and the third set temperature are the same.
10. A method of incinerating a hazardous waste slag plasma incinerator according to any one of claims 1 to 9, characterized in that: the method comprises the following steps:
starting a motor, pouring the hazardous waste slag into the cone crushing device from the feeding hole, wherein the motor works to drive a third bevel gear to rotate, the third bevel gear rotates to drive a fourth bevel gear to rotate, the fourth bevel gear rotates to drive a central shaft to rotate, and the central shaft rotates to drive a movable cone to rotate, so that the hazardous waste slag is crushed;
the broken hazardous waste slag enters a plasma melting furnace body for incineration and melting; the plasma in the plasma incinerator body and the hazardous waste slag are contacted with each other, a reaction process comprising cracking, gasification, melting and vitrification is carried out, so that at least part of organic substances in the hazardous waste slag are cracked to form mixed combustible gas, at least part of inorganic ingredients in the hazardous waste slag form molten slurry, the molten slurry is converted into molten glass liquid with a compact structure after being cooled, and metal ions with high boiling point in the molten glass liquid become molten alloy liquid and are precipitated at the lower part of the molten glass liquid;
when the temperature in the plasma incinerator body is higher than a first set temperature, the movable cone and the fixed cone are expanded, so that the gap between the movable cone and the fixed cone is reduced, the expansion disc is gradually expanded, and the transmission arm drives the transmission gear to rotate when the expansion disc is expanded; the central shaft, the transmission gear, the transmission sleeve and the first bevel gear rotate relatively, the first driven gear and the second driven gear start to rotate under the driving of the first bevel gear and the second bevel gear to rotate around the central shaft relative to the central shaft, the driven wheel frame and the worm are driven to rotate relative to the central shaft, the worm rotates to drive the worm wheel to rotate, the worm wheel rotates to drive the rack to move through the transmission gear, and then the axis of the inner cone and the axis of the movable cone are driven to move towards the axis of the fixed cone.
