[0037] The refining principle of the smelting furnace refining device of the present invention is as follows:

[0038] First, when preparing for installation of the present invention, close the electric valve 18 and rotate the threaded cover 20, place a refining agent for refining metal aluminum in the receiving bucket 19, wherein the refining agent is a mixture of sodium carbonate and sodium aluminate, then cover the threaded cover 20 and screw-lock the receiving bucket 19, the operator uses expansion bolts to position the four holes at the bottom of the support frame 17, drill holes at the ground position and insert the expansion bolts to support the support frame 17, after the bottom end of the support frame 17 is fixed at the ground position, the top ends of the four support frames 17 can provide support force to the bottom end of the smelting furnace body 1, and the metal aluminum in the five refining crucibles 16 inside the smelting furnace body 1 is melted by turning on the heater 21, and the electric valve 18 is opened to discharge the refining agent in the receiving bucket 19 into the refining crucible 16 for refining treatment, and the metal aluminum to be refined is added to the refining crucible 16 outside the smelting furnace body 1;

[0039] Secondly, when the present invention switches synchronously, the driving motor 5 is started by the controller 37 to drive the linkage screw 3 to rotate forward inside the support frame 2. At the same time, the linkage screw 3 drives the sleeve support ring 4 to move up along the support frame 2 under the action of the thread. At the same time, the sleeve support ring 4 drives multiple concave support blocks 6 to move the support shaft 7. The support shaft 7 drives the bottom end of the hinge sleeve 8 to move upward. The top end of the hinge sleeve 8 drives the sliding support shaft 9 to move the linkage concave block 10. The hinge sleeve 8 realizes a rotation operation on the sliding support shaft 9 and the support shaft 7. The movable support shaft 9 drives the sleeve slider 11 to move horizontally, and the sleeve slider 11 drives the limit support ring 22 to move the limit rotation shaft 12 horizontally, and the limit support ring 22 drives the switching seat 13 to separate the two fiber sealing strips 14 from the melting furnace body 1. The two fiber sealing strips 14 no longer seal the gap between the melting furnace body 1 and the switching seat 13. At the same time, the switching seat 13 drives the sleeve support block 15 to move the refining crucible 16 out of the melting furnace body 1, so that multiple refining crucibles 16 can be switched and removed synchronously.

[0040] Then, when the present invention is positioned and switched, the sleeve slider 11 drives the limiting rotating shaft 12 to make the switching seat 13 move horizontally, and the sleeve slider 11 slides along the outer wall of the guide slide bar 30 and the inner wall of the guide frame plate 29. At the same time, the sleeve slider 11 drives the distance sensor 28 to move. When the rubber ring 27 contacts the right side of the transmission motor 36, the distance sensed by the distance sensor 28 and the transmission motor 36 is the distance set by the controller 37, and the outer wall teeth of the linkage gear ring 23 can be engaged with the outer wall teeth of the drive gear ring 33. The controller 37 starts the reduction motor 40 to drive the transmission screw 39 to rotate forward inside the adjustment frame plate 38, and the transmission screw 39 drives the threaded sleeve 41 to move downward, and the threaded sleeve 41 drives the linkage support block 42 to make the linkage frame 44 move downward, and the linkage frame 44 makes the two limiting pillars 43 move downward, and the limiting pillars 43 and the guide ring 45 realize the separation operation, and the linkage frame 4 The rotation of the switching seat 13 is no longer limited, and the controller 37 starts the transmission motor 36 to drive the linkage shaft 32 to rotate. The linkage shaft 32 drives the driving gear ring 33 and the pulley 34 to rotate synchronously. The pulley 34 drives the linkage belt 35 to rotate. The linkage belt 35 can drive other pulleys 34 to rotate, so that multiple driving gear rings 33 can rotate synchronously. The driving gear ring 33 engages and drives the linkage gear ring 23 to rotate. The linkage gear ring 23 drives the two sensing blocks 24 to rotate. The linkage gear ring 23 also drives the limiting shaft 12 to rotate the switching seat 13. The switching seat 13 can drive the two socket support blocks 15 to rotate. The refining crucible 16 to be refined is switched to the position of the refining crucible 16 after refining. When the linkage gear ring 23 rotates 180 degrees and one of the sensing blocks 24 rotates to the sensing position of the proximity sensor 25, the transmission motor 36 is turned off by the controller 37.

[0041] Finally, when the present invention is synchronously docked, the controller 37 starts the reduction motor 40 to drive the transmission screw 39 to reverse inside the adjustment frame plate 38, the threaded sleeve block 41 drives the linkage support block 42 to move the linkage frame 44 upward, the limit pillar 43 and the guide ring 45 are plugged in and positioned, and the limit switching seat 13 is prevented from rotating. At the same time, the controller 37 starts the drive motor 5 to drive the linkage screw 3 to reverse inside the support frame plate 2, and the linkage screw 3 drives the sleeve support ring 4 to slide down along the guide inside the support frame plate 2 under the action of the thread. At the same time, the sleeve support ring 4 drives multiple concave support blocks 6 to move downward, and the concave support block 6 drives the support shaft 7 to make the hinge The sleeve rod 8 moves downward, and the hinged sleeve rod 8 drives the sliding support shaft 9 to move the linkage concave block 10 to the right. The linkage concave block 10 drives the sleeve sliding block 11 to reset to the right along the outer wall of the guide slide rod 30. At the same time, it uses the limit support ring 22 to move the limit rotating shaft 12 to the right. The limit rotating shaft 12 drives the switching seat 13 to make the other rotated fiber sealing strip 14 inserted into the inner wall of the switching seat 13, so that the refining crucible 16 to be refined is inserted into the interior of the smelting furnace body 1 to continue refining. After the refined metal aluminum is taken out synchronously, multiple metal aluminums to be refined can be switched synchronously and then enter the interior of the smelting furnace body 1 for refining.
