[0016] S3: Next, the filter cylinder rotates to centrifuge the pulping tailings, and as the push plate continuously moves forward, the tailings at the front end are further squeezed to fully separate the liquid in the tailings, until the three-phase contact with the connecting cylinder is made to push the fixed cover open, and the solid tailings separated at the front end are pushed into the first collecting cylinder, and the separation effect is remarkable;

[0017] S4: Next, when the push plate moves to the edge of the first fixed cylinder, the first gear starts to rotate clockwise, and the push plate moves backward, so that the fixed cover 1 is fixed to the first fixed cylinder again. At this time, the second water pump stops working, and the first water pump starts running. The pulping tailings flow into the front end of the push plate inside the filter cylinder through the first fixed cylinder. The operation is the same as above. The push plate moves backward to push the solid tailings separated from the rear end into the second collecting cylinder. This is repeated, and the work efficiency is improved with close cooperation.

[0018] Compared with the prior art, the present invention provides a waste paper pulping tailings recovery device and recovery method, which has the following beneficial effects:

[0019] 1. A waste paper pulping tailings recovery device and recovery method, the servo motor starts to work to rotate the first gear, and through a series of gear transmission, the filter cartridge is driven to rotate, and the pulping tailings liquid inside is thrown out through the centrifugal principle. When the filter cartridge rotates, the push plate arranged on the inside of the filter cartridge moves under the impetus of the first threaded rod, so that the push plate gradually approaches the tailings to squeeze it, and further squeezes out the residual liquid in the tailings, achieving the effect of centrifugation and squeezing, and fully separating the liquid in the tailings.

[0020] 2. This waste paper pulping tailings recovery device and recovery method, by setting instructions for the servo motor, makes the first gear rotate clockwise and counterclockwise alternately, and the filter cartridge also rotates clockwise and counterclockwise alternately, so as to cause the push plate to move back and forth. With the cooperation of the first water pump and the second water pump alternately injecting tailings, and through the continuous rotation of the filter cartridge, the tailings in the space in front of the push plate and the tailings liquid in the space behind it are separated simultaneously. The operation is continuous, and the separation effect is not affected. At the same time, the work efficiency is greatly improved, and the effect is remarkable.

[0021] 3. A waste paper pulping tailings recovery device and recovery method, when the push plate fully squeezes the liquid in the tailings, as the push plate continues to move, the push plate pushes open the fixed cover one or the fixed cover two through the connecting tube three, and the separated solid tailings can be directly pushed into the first collecting tube or the second slope plate, so as to completely realize solid-liquid separation, save manpower and have clear recovery, and can be well recycled to increase utilization and reduce pollution.

[0048] Specifically, when the push plate 45 moves backward, the connecting cylinder 1 47 and the connecting cylinder 2 48 located at the rear end are moved into the inner side of the connecting cylinder 3 49 in sequence until the fixing cover 2 6 is pushed open by the connecting cylinder 3 49 at the rear end. At the same time, the connecting cylinder 1 47 and the connecting cylinder 2 48 located at the front end are pulled out from the inner side of the connecting cylinder 3 49 in sequence, and so on.

Next, when the push plate 45 moves to the edge of the first fixed tube 1, the first gear 36 starts to rotate clockwise again through the command set by the servo motor 37, and then the push plate 45 moves backward. The fixed cover 5 is no longer subjected to the push force of the connecting tube 3 49, and the first spring 77 and the second spring 78 pop up, pushing the fixed cover 5 to be fixed to the front end of the first fixed tube 1.

[0053] A method for recovering waste paper pulping tailings comprises the following steps:

[0054] S1: Start the servo motor 37, the first gear 36 starts to rotate clockwise, and the filter cartridge 310 is driven to rotate continuously through the gear transmission. At this time, the push plate 45 moves backward, and then the first water pump 11 is started to extract the pulping tailings placed in the concentration tank 10 through the connecting pipe 13, and then pour it into the first fixed cylinder 1 through the feeding pipe 14, and then flow into the inner side of the filter cartridge 310. The liquid in the pulping tailings is thrown out from the inner side of the filter cartridge 310 to the inner side of the outer cylinder 31 through the centrifugal principle;

[0055] S2: When the filter cartridge 310 rotates, the inner push plate 45 continuously moves backwards through the screw principle until the push plate 45 pushes open the fixed cover 2 6 through the connecting tube 3 49, and then after the push plate 45 moves to the edge of the second fixed tube 2, the servo motor 37 is instructed to rotate the first gear 36 counterclockwise, so that the filter cartridge 310 starts to rotate in the opposite direction, prompting the push plate 45 to start moving forward, and then the fixed cover 2 6 is fixed to the second fixed tube 2 again. At this time, the first water pump 11 stops working, and the second water pump 12 starts running, so that the pulping tailings flow through the second fixed tube 2 into the rear end of the inner push plate 45 of the filter cartridge 310;

[0056] S3: Next, the filter cartridge 310 rotates to centrifuge the pulping tailings, and as the push plate 45 continuously moves forward, the tailings at the front end are further squeezed to fully separate the liquid in the tailings, until it contacts the connecting cylinder 3 49 to push open the fixed cover 1 5, and the solid tailings separated from the front end are pushed into the first collecting cylinder 17, and the separation effect is remarkable;

[0057] S4: Next, when the push plate 45 moves to the edge of the first fixed cylinder 1, the first gear 36 starts to rotate clockwise, and the push plate 45 moves backward, so that the fixed cover 5 is fixed to the first fixed cylinder 1 again. At this time, the second water pump 12 stops working, and the first water pump 11 starts running. The pulping tailings flow into the front end of the inner push plate 45 of the filter cylinder 310 through the first fixed cylinder 1. The operation is the same as above. The push plate 45 moves backward to push the solid tailings separated at the rear end into the second collecting cylinder 19. This is repeated, and the work efficiency is improved with close cooperation.

[0058] When in use, first start the servo motor 37 and set the command to make the first gear 36 start to rotate clockwise first, the first gear 36 rotates to mesh with the first gear ring 34 to make it start to rotate, the inner gear ring 35 rotates with the first gear ring 34 and then causes the second gear ring 311 to rotate through the second gear 315, so that the filter cartridge 310 starts to operate, and the first slide groove 41 is matched with the slider 44 to drive the push plate 45 to rotate on the first threaded rod 46. Through the screw principle, the push plate 45 moves backward under the restriction of the first slide groove 41, and then the first water pump 11 is started, and the pulping tailings placed in the concentration pool 10 are extracted through the connecting pipe 13, and then poured into the first fixed cylinder 1 through the feed pipe 14, and then flow into the inner side of the filter cartridge 310, and the pulping tailings are removed by the centrifugal principle. The liquid in the filter cartridge 310 is thrown out to the inner side of the outer cartridge 31, and then flows into the water bucket 9 through the water guide pipe 317. When the push plate 45 moves backward, the connecting cylinder 1 47 and the connecting cylinder 2 48 at the rear end are moved into the inner side of the connecting cylinder 3 49 in sequence, until the fixing cover 2 6 is pushed open by the connecting cylinder 3 49 at the rear end. At the same time, the connecting cylinder 1 47 and the connecting cylinder 2 48 at the front end are drawn out from the inner side of the connecting cylinder 3 49 in sequence. Then, after the push plate 45 moves to the edge of the second fixing cylinder 2, the servo motor 37 is instructed to rotate the first gear 36 counterclockwise, so that the filter cartridge 310 starts to rotate in the opposite direction, prompting the push plate 45 to start moving forward, and then the fixing cover 2 6 is fixed to the second fixing cylinder 2 again under the action of the fixing mechanism 7. At this time, the first water pump 11 stops. The second water pump 12 starts to operate, so that the pulping tailings flow into the rear end of the inner push plate 45 of the filter cartridge 310 through the second fixed cylinder 2. At the same time, the front end of the filter cartridge 310 rotates to centrifuge the pulping tailings. As the push plate 45 continues to move forward, the tailings at the front end are further squeezed to fully separate the liquid in the tailings until it contacts the connecting cylinder 3 49 to push open the fixed cover 5, and push the solid tailings separated at the front end into the first collecting cylinder 17. When the fixed cover 5 is pushed open, the fixed cover 5 and the threaded cylinder 75 rotate through the screw principle, and move forward along the second threaded rod 71, and rotate on the inner side of the rotating groove 2 72 through the rotating disk 73, so that the first spring 77 and the second spring 78 will not follow the fixed cover 1 when they are compressed. 5 rotates, and the slide bar 710 moves to the inner side of the support cylinder 79. Next, when the push plate 45 moves to the edge of the first fixed cylinder 1, the first gear 36 starts to rotate clockwise again through the command set by the servo motor 37, and then the push plate 45 moves backward. The fixed cover 15 is no longer subjected to the top force of the connecting cylinder 3 49. At the same time, the first spring 77 and the second spring 78 pop up, pushing the fixed cover 15 to be fixed to the front end of the first fixed cylinder 1, and the push plate 45 has moved to the inner side of the filter cylinder 310. At this time, the second water pump 12 stops working, and the first water pump 11 starts running. The pulping tailings flow through the first fixed cylinder 1 into the front end of the push plate 45 on the inner side of the filter cylinder 310. The operation is the same as above. The push plate 45 moves backward to push the solid tailings separated at the rear end into the second collecting cylinder 19.Repeat this process and cooperate closely.
