[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting the suction device, when the feeding hopper is rotating, when the sealing cover plate contacts the outer wall of the isolation frame and encounters resistance, the sealing cover plate will be pushed to rotate. When the placement slot and the feed port of the isolation frame are misaligned, the sealing cover plate rotates 90 degrees and presses on the top of the rectangular frame to seal the inside of the placement slot. At the same time, the vacuum pump is started to suck the inside of the rotating rod, so that the oxygen inside the placement slot is pumped to the outside through the bellows, so that when the placement slot is rotated to align with the feed port of the feeding hopper, the oxygen inside the placement slot can be pumped away, and then the solenoid valve is opened, so that the gas inside the refining tank can enter the placement slot, so that the inside of the placement slot is no longer in a negative pressure state, so that the sealing cover plate is reset under the action of the torsion spring, and then the inside of the placement slot is opened, so that the aluminum block can slide down easily, so that the aluminum block can be isolated from oxygen when being fed into the refining tank, so as to prevent oxygen from entering the refining tank, thereby improving the refining effect of the aluminum block;

[0016] 2. By setting up a self-feeding feeding mechanism, the output end of the driving motor drives the second bevel gear to rotate, thereby driving the first bevel gear to drive the rotating rod to rotate in a circle, and then driving the feeding hopper to drive the aluminum block inside to rotate. When the placement slot is aligned with the feeding hopper, the aluminum block inside the placement slot slides into the feeding hopper and falls into the refining tank, thereby realizing the function of aluminum block feeding;

[0017] 3. By setting an intermittent lifting mechanism, the spur gear ring partially has no teeth meshing with the second spur gear. When the sealing cover plate and the rectangular frame are sealed during the rotation of the feed hopper, the second spur gear meshes with the teeth on the outer wall of the spur gear ring, so that the spur gear ring can drive the second spur gear to rotate, and then drive the disc to rotate in a circle. Under the action of the connecting column, the circular frame is pushed to drive the spur rack to move back and forth horizontally through the connecting rod, thereby driving the first spur gear to drive the rotating plate to reciprocate within a range of ten degrees through the rotating shaft, thereby avoiding the aluminum block being pressed on the circular frame and being blocked, thereby ensuring the stability of suction inside the placement tank.

[0036] Example 3

[0037] An intermittent lifting mechanism is provided inside the placement groove 7 to assist the movement of the port of the bellows 12. The intermittent lifting mechanism includes a rotating plate 10 arranged on the inner side of the placement groove 7. A movable groove 36 is provided inside the rotating plate 10. An air inlet 37 communicating with the movable groove 36 is provided at the bottom of the movable groove 36. One end of the bellows 12 is installed at the port of the air inlet 37. A rectangular filter plate 38 is installed on the front of the rotating plate 10. A power toggle member that penetrates to the outside of the feeding hopper 5 is provided on one side of the rotating plate 10. The intermittent lifting mechanism also includes a sliding filter plate 9 slidably connected to the inside of the movable groove 36. A telescopic stopper 8 is fixedly connected to one end of the sliding filter plate 9, and the telescopic stopper 8 abuts against the inner side of the placement groove 7. A connecting spring 11 is fixedly connected to the other end of the sliding filter plate 9, and one end of the connecting spring 11 is fixedly connected to the rotating plate 10. The power toggle member includes a rotating shaft 22 fixedly connected to one side of the rotating plate 10, and one end of the rotating shaft 22 penetrates to the outside of the feeding hopper 5. The outer wall of the rotating shaft 22 is fixedly connected with the first straight gear 26, one side of the feeding hopper 5 is rotatably connected with a rotating shaft 33, one end of the rotating shaft 33 is fixedly connected with a disc 30, one side of the disc 30 is fixedly connected with a connecting column 31, the outer wall of the connecting column 31 is sleeved with a circular frame 28, one side of the circular frame 28 is fixedly connected with a connecting rod 27, one end of the connecting rod 27 is fixedly connected with a straight rack 25 meshing with the first straight gear 26, and the isolation frame 3 A connecting block 39 is fixedly connected to the inner side, one end of the connecting block 39 is fixedly connected to the spur gear ring 21, a second spur gear 29 meshing with the spur gear ring 21 is fixedly connected to the outer wall of the rotating shaft 33, a circular groove 32 matching the connecting column 31 is provided on the inner side of the circular frame 28, a slider 23 is fixedly connected to one side of the spur rack 25, a limiting groove 24 matching the slider 23 is provided on one side of the feeding hopper 5, and the spur rack 25 is slidably connected to the feeding hopper 5 through the slider 23;

[0038] The spur gear ring 21 has no teeth meshing with the second spur gear 29 in part. When the sealing cover plate 4 and the rectangular frame 14 are sealed during the rotation of the feed hopper 5, the second spur gear 29 meshes with the teeth on the outer wall of the spur gear ring 21, so that the spur gear ring 21 can drive the second spur gear 29 to rotate, thereby driving the disc 30 to rotate in a circle, and under the action of the connecting column 31, the circular frame 28 is pushed to drive the spur rack 25 to move back and forth horizontally through the connecting rod 27, thereby driving the first spur gear 26 to drive the rotating plate 10 to reciprocate within a range of ten degrees through the rotating shaft 22, thereby avoiding the aluminum block from being pressed on the circular frame 28 and being blocked, thereby ensuring the stability of the suction inside the placement groove 7;

[0039] When the rectangular filter plate 38 rotates toward the inside of the placement groove 7, the telescopic stopper 8 always presses against the inner side of the placement groove 7 under the action of the connecting spring 11, thereby ensuring that the rotating plate 10 can be stably reset, thereby improving the overall practicality of the device.

[0040] When the placement slot 7 is aligned with the feed port of the feed hopper 2, the aluminum block inside the placement slot 7 can be actively pushed by the reciprocating swing of the rotating plate 10, thereby avoiding the aluminum block from getting stuck inside the placement slot 7, thereby improving the overall practicality of the device.

[0041] Working principle:

[0042] First, when the aluminum block is placed in the placement slot 7 and needs to be loaded into the refining tank 1, the drive motor 16 can be started first, and the output end of the drive motor 16 drives the second bevel gear 19 to rotate, thereby driving the first bevel gear 18 to drive the rotating rod 6 to rotate in a circle, and then driving the feeding hopper 5 to drive the aluminum block inside to rotate. When the placement slot 7 is aligned with the feeding hopper 2, the aluminum block inside the placement slot 7 slides into the feeding hopper 2 and falls into the refining tank 1, thereby realizing the function of loading the aluminum block;

[0043] When the feeding hopper 5 is rotating, when the sealing cover plate 4 contacts the outer wall of the isolation frame 3 and encounters resistance, the sealing cover plate 4 will be pushed to rotate. When the placement slot 7 is misaligned with the feed port of the isolation frame 3, the sealing cover plate 4 rotates ninety degrees and presses on the top of the rectangular frame 14, so as to seal the inside of the placement slot 7. At the same time, the vacuum pump 17 is started, and the vacuum pump 17 sucks the inside of the rotating rod 6, so that the oxygen inside the placement slot 7 is pumped to the outside through the bellows 12, so that when the placement slot 7 is rotated to align with the feed port of the feeding hopper 2, the oxygen inside the placement slot 7 can be pumped away, and then the solenoid valve 15 is opened, so that the gas inside the refining tank 1 can enter the placement slot 7, so that the inside of the placement slot 7 is no longer in a negative pressure state, so that the sealing cover plate 4 is reset under the action of the torsion spring 35, and then the inside of the placement slot 7 is opened, so as to facilitate the sliding of the aluminum block, so that the aluminum block can be isolated from oxygen when being fed into the refining tank 1, so as to prevent oxygen from entering the refining tank 1, thereby improving the refining effect of the aluminum block;

[0044] The spur gear ring 21 partially does not have teeth meshing with the second spur gear 29. When the sealing cover plate 4 and the rectangular frame 14 are sealed during the rotation of the feed hopper 5, the second spur gear 29 meshes with the teeth on the outer wall of the spur gear ring 21, so that the spur gear ring 21 can drive the second spur gear 29 to rotate, and then drive the disc 30 to rotate in a circle. Under the action of the connecting column 31, the circular frame 28 is pushed to drive the spur rack 25 to move back and forth laterally through the connecting rod 27, thereby driving the first spur gear 26 to drive the rotating plate 10 to reciprocate within a range of ten degrees through the rotating shaft 22, thereby avoiding the aluminum block being pressed on the circular frame 28 and being blocked, thereby ensuring the stability of suction inside the placement groove 7.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
