At this time, the transmission plate 1805 will drive the corresponding pusher rack 1802 to move through the docking plate 1804.

[0048] Working principle: When using the wastewater treatment device for polypropylene fiber printing and dyeing processing, first, the polypropylene fiber printing and dyeing wastewater is sent into the first-level box 1 and the middle cylinder 3. The feeding device arranged on the top side wall of the first-level box 1 is used to feed flocculants, so that the wastewater in the first-level box 1 can produce flocculated sediments. In this process, the third electric cylinder 21 can drive the rotating connection disk 20 to move back and forth, and the connection disk 20 will drive the moving plate 19 to move synchronously, and the moving plate 19 drives the outer pressure shell 1801 to move synchronously, so that the outer pressure shell 1801 can push the wastewater in the first-level box 1 and the middle cylinder 3 to accelerate flocculation. After a period of time, the sediment will accumulate on the top of the sealing block 10 in the middle cylinder 3, and the moving plate 19 will reset at the same time. Then the first electric cylinder 6 pushes the arc filter plate 5 to move downward along the inner wall of the first-level box 1. At this time, the arc filter plate 5 can filter the clarified water in the first-level box 1 again;

[0049] When the inner wall of the arc filter plate 5 is flush with the inner wall of the middle cylinder 3, the servo motor 9 is started. At this time, the output gear of the servo motor 9 will drive the rotating shaft 7 to rotate through the transmission gear ring 8, and the rotating shaft 7 will drive the filter press plate 17 to move, so that the top of the filter press plate 17 can rotate along the inner wall of the arc filter plate 5 and the middle cylinder 3 to play a cleaning role. At the same time, the filter press plate 17 can further filter the water in the middle cylinder 3. In this process, as the rotating shaft 7 rotates, the drain channel 22 on the rotating shaft 7 will no longer be blocked by the sealing block 10, and the clarified water filtered by the filter press plate 17 will flow into the secondary box 2 through the drain channel 22. When the filter press plate 17 drives the outer pressure shell 1801 to fit the top of the sealing block 10 After the other side, the device can control the third electric cylinder 21 to reciprocate in a small range according to the set pressure, so that the outer pressure shell 1801 can further squeeze the collected sediment, and the second electric cylinder 16 is started. At this time, the second electric cylinder 16 will drive the blocking block 15 and the pressure rod 13 to move synchronously through the thrust frame 14, so that the blocking block 15 opens the drain port at the bottom of the first-stage box 1 to discharge the remaining clarified water, and the water will flow into the second-stage box 2, and the pressure rod 13 pulls the locking head 12 to move through the spring, so that the locking head 12 can be away from the positioning hole 11 on the sealing block 10. At this time, the rotating shaft 7 rotates again, and the rotating shaft 7 can drive the sealing block 10 to rotate through the filter plate 17 and the outer pressure shell 1801;

[0050] When the filter plate 17 rotates to a position vertically downward toward the slag discharge pipe 4, the sediment accumulated between the filter plate 17 and the sealing block 10 will be discharged, and the rotating shaft 7 drives the cross bar 28 to rotate through the thrust plate 25 and the inner core rod 27, and the support tube 32 at the end of the rotating shaft 7 drives the storage tube 30 to rotate synchronously. At this time, the cross bar 28 will pass through the hemispherical block 33. During this process, the second electric cylinder 16 drives the thrust frame 14 to reset, so that the locking head 12 can be pressed against the sealing block 10 under the action of the spring until the locking head 12 enters the positioning hole 11 of the sealing block 10 again. After that, the servo motor 9 will drive the rotating shaft 7 to rotate back and forth at a set angle, so that the cross bar 28 can continuously pass through the hemispherical block 33. Under the pushing action of the hemispherical block 33, the cross bar 28 will drive the sleeve 29 to move into the storage tube 30, and the sleeve 29 will further compress the reset spring 31, and the reset spring 31 can push the sleeve 29 to reset. When the sleeve 29, the cross bar 28 and the inner core rod 27 will move back and forth synchronously, the inner core rod 27 will drive the force block 24 to move back and forth through the inclined groove 26 on the thrust plate 25, the force block 24 will drive the guide plate 23 to move synchronously, and the guide plate 23 will drive the transmission plate 1805 to move through the limit block 1806, at this time the transmission plate 1805 will drive the corresponding pusher frame 1802 to rotate around the rotating shaft 1803 through the docking plate 1804, the arc plate on the pusher frame 1802 can extend from the outer pressure shell 1801, so as to accelerate the discharge of the sediment collected on the sealing block 10, during this process, the device can control the third electric cylinder 21 to start, the third electric cylinder 21 drives the outer pressure shell 1801 to move through the connecting disk 20 and the moving plate 19, so that the outer pressure shell 1801 can move on the filter plate 17 for cleaning, and the limit block 1806 at the bottom of the transmission plate 1805 will slide synchronously in the slide groove at the top of the guide plate 23;

[0051] After the sediment is discharged, the second electric cylinder 16 drives the thrust frame 14 to move, so that the sealing block 10 is released from the limit, and then the rotating shaft 7 drives the sealing block 10 to rotate and return to its original position through the filter press plate 17. At the same time, the second electric cylinder 16 is reset, so that the sealing block 10 is locked again. At the same time, the servo motor 9 drives the rotating shaft 7 and the filter press plate 17 to reset, and the first electric cylinder 6 drives the arc filter plate 5 to reset. At the same time, the feeding equipment arranged on the side wall of the secondary box 2 will discharge the reagent, and use the reagent to perform acid-base neutralization and other reaction operations on the clarified water in the secondary box 2, and the treated water in the secondary box 2 will be discharged through the solenoid valve pipe at the bottom.
