The top of the base 1 is provided with the circular fixing frame 61 in a bolted manner. The base 1 is provided with a circle of material guide grooves, and the center of the material guide grooves coincides with the center of the circular fixing frame 61. A circle of arc-shaped guide rails 62 is arranged around the axis of the circular fixing frame 61. Ball bearings are arranged in the groove bodies of the arc-shaped guide rails 62 in a rotating manner. The bottom of the circular rotating plate 63 is provided with an annular sliding block. The circular rotating plate 63 is slidingly installed on the arc-shaped guide rails 62 through the annular sliding block. The bottom center of the circular rotating plate 63 is provided with the mounting block 64. The mounting block 64 is provided with the ratchet wheel 65 in an interference connection manner. A one-way sliding slot is formed in the right side of the top of the base 1. The sliding block 66 is slidingly arranged in the one-way sliding slot of the base 1.

[0033] As shown in the figure, Figure 1 and Figure 7 The fixing mechanism 7 comprises a support plate 71, a moving rod I 72, a wedge-shaped top block 73, a second elastic member 74, an N-shaped frame 75 and a clamping plate 76. The left side of the top of the base 1 is provided with the support plate 71. The protrusions in the middle and the top of the support plate 71 are both vertically slidingly provided with the moving rod I 72. The bottom ends of the moving rod I 72 are provided with the wedge-shaped top block 73. The second elastic member 74 is arranged between the wedge-shaped top block 73 and the protrusions of the support plate. The second elastic member 74 is a compression spring. The top ends of the moving rod I 72 are provided with the N-shaped frame 75. The clamping plate 76 is arranged on the half-arc rotating frame 3. The clamping groove on the clamping plate 76 cooperates with the wedge-shaped top block 73.

[0034] When the device is used, the staff starts the air cylinder to continuously stretch and shrink, and then drives the ratchet bar 68 to continuously move forward and backward. When the ratchet bar 68 moves backward, it cooperates with the ratchet wheel 65 to push the tooth transverse surface of the ratchet wheel 65, and then drives the ratchet wheel 65 to rotate. The ratchet wheel 65 drives the mounting block 64 and the circular rotating plate 63 to rotate. At the same time, the teeth of the ratchet wheel 65 press the inclined surface of the ratchet tooth 611 on the left side, and the ratchet tooth 611 moves backward. The first elastic element 612 is compressed. When the ratchet bar 68 moves backward and is separated from the ratchet wheel 65, the ratchet wheel 65 stops rotating. The first elastic element 612 drives the ratchet tooth 611 to reset and be clamped between two teeth of the ratchet wheel 65, and then the fixation of the ratchet wheel 65 is completed. When the air cylinder drives the sliding block 66 and the ratchet bar 68 to move forward, the ratchet tooth 611 fixes the ratchet wheel 65. Since the ratchet bar 68 is in contact with the tooth inclined surface of the ratchet wheel 65, the ratchet wheel 65 cannot rotate in the opposite direction. Therefore, the tooth inclined surface of the ratchet wheel 65 continuously presses the ratchet bar 68, and the ratchet bar 68 drives the cylindrical rod 67 to move to the right. The first elastic element 612 is compressed. When the ratchet bar 68 is separated from the ratchet wheel 65 again, the first elastic element 612 drives the ratchet bar 68 and the cylindrical rod 67 to reset. The intermittent rotation of the rotating placing mechanism 6 is realized. The staff places the bags containing neodymium iron boron waste along the axis of the circular rotating plate 63 at intervals. When the stack reaches a certain height, the staff rotates the semicircular rotating frame 3. The semicircular rotating frame 3 cooperates with the semicircular fixed frame 2 to form a closed area. The clamping plate 76 presses the inclined surface of the wedge-shaped top block 73. The wedge-shaped top block 73 drives the moving rod I 72 to move upward. The second elastic element 74 is compressed. When the wedge-shaped top block 73 faces the clamping groove of the clamping plate 76, the second elastic element 74 drives the moving rod I 72 and the wedge-shaped top block 73 to reset. The wedge-shaped top block 73 is clamped into the clamping groove of the clamping plate 76, and then the locking of the semicircular fixed frame 2 and the semicircular rotating frame 3 is completed. The staff pushes the annular block 51 to move forward. When the circular heavy block 531 leaves the support on the top of the semicircular fixed frame 2, it falls onto the stacked bags containing neodymium iron boron waste between the semicircular fixed frame 2 and the semicircular rotating frame 3. The circular heavy block 531 presses the bags containing neodymium iron boron waste. The waste water inside is squeezed out and flows into the guide groove of the base 1 through the annular baffle 613, and then flows out for collection. After a period of time, the waste water in the bags containing neodymium iron boron waste no longer flows out. The staff starts the electric winding wheel I 55 to wind the pull rope I 58. The pull rope I 58 drives the circular heavy block 531 to move upward. The slide rod 53 is inserted into the guide sleeve 52. When the circular heavy block 531 is flush with the annular block 51, the staff pulls the annular block 51 backward. The semicircular fixed frame 2 and the support frame 10 support the circular heavy block 531. At the same time, the electric winding wheel I 55 stops working. Pulling the N-shaped frame 75 upward, the N-shaped frame 75 drives the moving rod I 72 and the wedge-shaped top block 73 to move upward. The wedge-shaped top block 73 is separated from the clamping groove of the clamping plate 76. The semicircular rotating frame 3 can be opened. The staff can carry the neodymium iron boron waste from which the waste water has been separated for further processing. The device has a simple structure and is easy to operate.
