s3, when the dissolving tank (4) rotates anticlockwise, the dissolving liquid and the rare metal waste slag in the dissolving tank (4) slide to the left side, and when the dissolving liquid flows to the left side, the floating plate (13) moves upwards under the action of the buoyancy of the dissolving liquid, the floating plate (13) drives the closing plate (12) to slide upwards through the first pull rope (14), so that the discharge hole (11) is opened, and when the dissolving tank (4) rotates, when the gravity of the fixed plate (16) is larger than the friction force of the fixed plate (16) and the dissolving tank (4), the fixed plate (16) slides along the sliding plate (17) in an inclined downward mode, the fixed plate (16) pulls the floating plate (13) and the closing plate (12) upwards through the second pull rope (15), so that the opening state of the discharge hole (11) is kept;
s4, the dissolving solution and rare metals in the dissolving tank (4) enter the filter tank (18) through the discharge hole (11) and the guide pipe (46), at the moment, the rotating motor (27) still drives the rotating rod (23) and the reciprocating screw (24) to rotate, when the dissolving solution and the rare metals fall on the coarse filter plate (20), the coarse filter plate (20) firstly screens the large-particle rare metals in the dissolving solution and the rare metals, then screens the small-particle rare metals through the fine filter plate (19), the rotating rod (23) can drive the fixed blocks (21) to rotate when rotating, along with the rotation of the fixed blocks (21), when the two fixed blocks (21) respectively contact with the bottom parts of the right sides of the coarse filter plate (20) and the fine filter plate (19), the two fixed blocks (21) can respectively drive the fine filter plate (19) and the coarse filter plate (20) to move upwards, and when the fixed blocks (21) leave, the fine filter plate (19) and the coarse filter plate (20) fall again under the self gravity factor, and then the fine filter plate (19) and the coarse filter plate (20) can vibrate up and down;
s5, along with the vibration of the fine filter plates (19) and the coarse filter plates (20), filtered rare metals fall on the metal filter plates (37) in the material collecting box (29) through the discharge port (28), and can drive the second synchronous wheel (33) to rotate when the rotating rod (23) rotates, the second synchronous wheel (33) drives the second rotating shaft (31) and the fan (35) to rotate through the synchronous belt (34) and the first synchronous wheel (32), then the resistance wire heating pipe (36) is started, and when the fan (35) rotates, the fan (35) can blow air heated by the resistance wire heating pipe (36) downwards.
