Meanwhile, the contents which are not described in detail in the specification belong to the prior art known to the person skilled in the art, and model parameters of each electric appliance are not particularly limited and conventional equipment can be used.

When the crucible is used, the crucible 1 filled with raw materials is firstly placed inside the clamping frame 37, the annular cavity 371 is inflated through the air pump station 6, air enters the air bag 375 through the communicating hole 373, the arc-shaped plug bush 374 is pushed towards the middle to clamp the side face of the crucible 1, then the arc-shaped plug bush is inflated into the second air cylinder 36 to push the clamping frame 37 upwards to jack up, the support frame 32 is pushed backwards, the crucible 1 is fed into the protective cover 221, the air in the second air cylinder 36 and the air bag 375 are sequentially pumped out, the crucible 1 can be lowered onto the lifting platform 224 and then is released, the clamping frame 37 is lifted, and the support frame 32 and the upper clamping frame 37 are pulled out.

The first cylinder 23 is contracted to lower the whole feeding and discharging mechanism 22, the protective cover 221 firstly descends, at the moment, the lifting platform 224 is locked by the positioning component 222 and cannot descend, the protective cover 221 utilizes the lug 2214 to push down the wavy elastic sheet 2213, further drives the rack 2212 to descend, further drives the second gear 2211 to rotate, drives the sleeve 227 to rotate by utilizing the meshing of the first bevel gear 229 and the second bevel gear 2210, further drives the rotating shaft 22212 to rotate by utilizing the torsion spring 228, enables the first gear 22211 to cooperate with the tooth socket 22210 to push the rotary table 2228 to rotate, simultaneously pushes the circular shaft 2227 to rotate, enables the inserting block 2226 to slide out of the slot 226 on the side surface of the lifting platform 224, at the moment, the lifting platform 224 can drive the crucible 1 to descend until the lifting platform 224 falls to the bottom of the inner cavity of the furnace body 21, and the sealing plate 225 also falls to the top of the furnace body 21 to cover the top of the furnace body 21 under the pressure of the lower layer spring 2216, and then the vortex heating component 213 is started to smelt raw materials.

After smelting, the above steps are reversed, the crucible 1 is taken out and transferred to the upper part of the transfer trolley 4, then the clamping frame 37 and the crucible 1 are lowered, the bottom of the crucible 1 is inserted into the heat preservation sleeve 43, then the clamping frame 37 is controlled to loosen the crucible 1, the crucible 1 can naturally fall down, and because the gap between the crucible 1 and the heat preservation sleeve 43 is smaller, air is slowly extruded from the side surface, the crucible 1 slowly falls down until the crucible falls to the bottom (when the crucible needs to be taken out, the valve 44 can be opened to increase the gas flow quantity, so that the crucible 1 can be quickly taken out), and then the bolts 49 are rotated to block the top edge of the crucible 1, so that the crucible 1 is prevented from sliding out during dumping.

When the crucible 1 is transported, the heat-insulating cover can be covered on the top, and when the crucible 1 is transported to a casting point, the heat-insulating cover is taken down, the stop lever 45 is pulled out, the steel wire rope 46 pulls the heat-insulating sleeve 43 and the crucible 1 therein to deflect by pulling the handle 47, and the internal solution is poured out.

It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
