The working principle is as follows: when the device is used, raw materials are simply chopped and then are sent into the feeding cavity 21, then the raw materials pass through the feeding cavity 21 and enter the material guide pipe 32, the feeding amount is based on that the crucible 25 can be just filled, at the moment, the main lifting push rod 32 pushes the bevel sealing block 31 downwards to enable the bevel sealing block 31 to be separated from the matching state with the material guide pipe 32, so that the materials in the material guide pipe 32 can slide into the crucible 25 through the upper part of the bevel sealing block 31, after the crucible 25 is filled, the bevel sealing block 31 returns to the sealing state with the material guide pipe 32 again, at the moment, the first push rod 8 drives the first sealing plate 14 to seal the feeding cavity 21, then the materials which are enough for secondary feeding are filled into the feeding cavity 21 through the opening of the inclined material guide shell 9, then the second push rod 11 drives the second sealing plate 12 to seal the upper end of the feeding cavity 21, and then the feeding cavity 21 and the working cavity 37 are respectively pumped by the first air pump 20 and the second air pump 17, so that the feeding cavity 21 and the working cavity 37 are in a negative pressure state, the heater 36 starts to heat the material in the crucible 25 to melt the material, after the material is completely melted, the first push rod 8 drives the first closing plate 14 to open, so that the material required by the secondary feeding moves into the material guiding pipe 32 to close the first closing plate 14 again, then the second closing plate 12 opens to feed the material required by the secondary feeding into the feeding cavity 21 for two rounds from the inlet end of the inclined material guiding shell 9 to process the required first feeding material, then the second closing plate 12 is closed and the feeding cavity 21 is pumped into the negative pressure state again, and at this time, the main lifting push rod 13 can drive the bevel closing block 31 to open downwards so that the material in the material guiding pipe 32 for the secondary feeding can enter the crucible 25 to be refilled with the crucible, and then the bevel closing block 31 returns to the closed state with the material guiding pipe 32 again, in the secondary feeding process, in order to avoid splashing the melted metal when the material dropped from the material guiding pipe 32 falls into the crucible 25, the auxiliary lifting push rod 15 may be used to move the end of the material guiding pipe 32 downward to a position closer to the crucible 25, and then the material guiding pipe is lifted again after the feeding is completed. Because the working chamber 37 is already pumped to a negative pressure state, the heater 36 in the working chamber 37 mainly heats the crucible 25 in a heat conduction mode, only a small amount of heat is transferred to other equipment in the working chamber 37 in a heat radiation and heat convection mode, the temperature rise is slow due to low heat conduction efficiency, and the critical equipment in the working chamber 37 can be cooled by liquid cooling equipment arranged outside in a liquid cooling mode after being wound with a liquid cooling pipe, so that the influence of high temperature can be almost ignored. The second air pump 17 can continuously pump in the smelting process, so that waste gas generated in the smelting process can be pumped out in time, in addition, corresponding gas can be supplied through the reaction gas feeding pump 7 in the process of smelting waste metal requiring additional reaction gas supply, the gas is firstly fed into the nozzle 34 through the reaction gas feeding pump 7 and then is sprayed out in a high-pressure airflow mode through the nozzle 34, the height position of the nozzle 34 can also be driven by the auxiliary lifting push rod 15 to be adjusted up and down, so that the reaction gas can better contact and react with materials, the gas supplied in the reaction and the gas generated after the reaction are also quickly pumped out through the second air pump 17, and after the smelting of the raw material in the crucible 25 is completed, the bottom adjusting push rod 25 drives the crucible 25 to move downwards and be separated from the matching with the heater 36, when the crucible 25 is rotated, the molten metal is poured into the material receiving cavity 35 along the pouring nozzle 26, then the discharge valve 3 is opened to enable the molten metal to flow downwards along the discharge pipe 4, after pouring is finished, the crucible 25 is rotated again to return to a normal angle under the driving of the direction adjusting push rod 22, and then the crucible is inserted again into a position matched with the heater 36 under the driving of the bottom adjusting push rod 29 to wait for smelting of the next round. In order to avoid the external air from entering the working chamber 37, the second air pump 17 may be turned off before the crucible 25 is tilted, and then the shielding gas provided by the external shielding gas supply device is sent into the working chamber 37 by the shielding gas sending pump 6 so as to temporarily return the normal air pressure in the working chamber 37, the shielding gas may be argon gas, and after the tilting is completed, the second air pump 17 is used again to pump the inside of the working chamber 37 to a negative pressure state close to vacuum. The waste metal smelting furnace provided by the invention can realize secondary feeding of the interior of the crucible 25 by using a secondary feeding mechanism consisting of the material guide pipe 32, the main lifting push rod 13, the moving rod 33 and the inclined plane sealing block 31, so that the utilization efficiency of the interior space of the crucible 25 is effectively improved, the production efficiency is improved, the interior of the device can be ensured to be in a negative pressure state by a special structural design and the real-time air suction effect of the second air suction pump 17, the heat loss is effectively reduced, the utilization efficiency of heat is improved, the damage to other equipment caused by excessive heat accumulation in the working cavity 37 can be effectively avoided, the service life of the equipment is effectively prolonged, in addition, the device also has continuous smelting capacity, the production efficiency can be further improved, and the device has high practical value.
