[0001] The utility model belongs to the technical field of papermaking production and processing, and specifically relates to a pulp fiber separator. Background Art

[0002] The pulp fiber separator utilizes the specific gravity difference between waste paper pulp and impurities to remove light and heavy impurities in waste paper raw materials, and has the functions of loosening and screening. It is mainly used to separate light and heavy sundries in waste paper pulp and perform secondary shredding on the pulp, thereby improving the quality and production efficiency of the pulp.

[0003] The prior art discloses a fiber separation device for non-woven fabric production (CN208309269U), including a box body, a discharge pipe and a feed pipe. When the present utility model works, under the action of a first motor, a lead screw and a lead screw slider, a moving platform and a rotating platform are driven to perform horizontal reciprocating motion. Under the action of a second motor and a central rotating shaft, a spiral blade is driven to rotate and the rotating platform rotates accordingly. The spiral blade rotates and moves to break and stir the pulp, improving the pulping efficiency and uniformity. A filter screen performs primary separation on the pulp fibers. Under the action of a third motor, an output rotating shaft, a rotating connecting rod, a swinging slider, a limit pin, a swinging connecting rod, a swinging slider and a swinging central shaft, a pressing roller shaft is driven to repeatedly roll the pulp, and secondary separation of the pulp fibers for non-woven fabric production is performed under the action of gravity and extrusion force, improving the fiber separation effect of the pulp. The inner wall of the box body can be automatically cleaned by a reciprocatingly moving and rotating spray head, improving the service life of the device and ensuring the working effect of the device.

[0031] The working principle is as follows. By setting a two-way mixing component, the device uses the driving gear 25 to drive the rotation of the gear box 21 and the half gear 22, so that the half gear 22 cooperates with the gear box 21 to respectively engage the gear ring 24, so that the gear ring 24 drives the stirring blade 28 to move in two opposite directions, so as to break and stir the slurry in two directions, and use the impact force of the two-way rotation to increase the contact surface between the stirring blade 28 and the slurry, so as to avoid stirring dead angles to a certain extent, and then strengthen the mixing effect of the slurry and improve the uniformity; By setting an extrusion component, the half gear 22 cooperates with the gear box 21 to engage the same gear ring 24 from two directions, so that the gear ring 24 drives the moving disk 26 to rotate in two opposite directions, and the shape of the moving disk 26 is used to mobilize the extrusion plate 34, and then drive the extrusion plate 34 to slide in the guide block 29 to realize extrusion and contraction, so as to separate the slurry in the machine shell 10, and the separated snap-fit design of the internal structure of the device is more convenient to clean after use, so that the device is cleaner and more hygienic.

[0033] Specifically, a discharge port is opened inside the machine shell 10, and the discharge port communicates with the inner circle of the discharge pipe 11. A feed port is opened inside the barrel cover 12, and the feed port communicates with the inner circle of the feed hopper 13. The filter cylinder 14 is designed as a hollow circular ring. The diameter of the filter cylinder 14 is smaller than that of the machine shell 10. The diameter of the snap ring 15 is smaller than that of the filter cylinder 14. The height of the snap ring 15 is one-fifth of that of the filter cylinder 14. The outer diameter of the filter screen 16 is less than or equal to the inner diameter of the filter cylinder 14, and the inner diameter of the filter screen 16 is greater than or equal to the outer diameter of the snap ring 15.

[0034] As Figure 2 and Figure 4 shown, rotation holes 17 are opened inside both the barrel cover 12 and the guide block 29. A sleeve column 27 is rotatably arranged in the rotation holes 17. The top end of the sleeve column 27 is fixedly connected to the gear ring 24, the bottom end of the sleeve column 27 is fixedly connected to the moving disk 26, and a stirring blade 28 is fixedly connected inside the sleeve column 27; As Figure 1 , Figure 2 and Figure 4As shown in the figure, a bracket 19 and two fixed columns 20 are fixedly connected to the top surface of the bucket lid 12. The two fixed columns 20 are symmetrically arranged with the rotation hole 17 as the center. The half gear 22 is rotatably connected to one of the fixed columns 20 through a bearing, and the driving gear 25 is rotatably connected to the other fixed column 20 through a corresponding bearing; As Figure 2 and Figure 4 shown, the gear box 21 is a circular box structure. An annular rack 23 is fixedly connected to the inner wall surface of the gear box 21. The bucket lid 12 is fixedly provided with a motor 18 through the bracket 19. The output end of the motor 18 is connected to the top surface of the driving gear 25. The driving gear 25 meshes with the gear box 21. The half gear 22 and the annular rack 23 mesh and drive the same gear ring 24; As Figure 5 shown, the guide block 29 is fixedly connected to the bottom surface of the nail-shaped column. Seven sliding grooves 30 are formed around the bottom of the guide block 29. A sliding block 33 is fixedly connected to the top surface of the pressing plate 34. The sliding block 33 slides in the sliding groove 30; As Figure 5 shown, the pressing plate 34 is fixedly arranged at one end of the bottom surface of the sliding block 33.

[0035] The specific implementation method is as follows. Before use, first snap the filter screen 16 into the annular groove formed between the filter cylinder 14 and the snap ring 15, and then snap the bucket lid 12 above the machine shell 10 and the filter cylinder 14. Start the motor 18. The motor 18 drives the driving gear 25 to rotate. The driving gear 25 meshes with the gear box 21. The gear box 21 drives the synchronous rotation of the half gear 22 and the annular rack 23. At this time, since the half gear 22 and the annular rack 23 face the same direction, when the half gear 22 meshes and drives the gear ring 24, the gear ring 24 drives the sleeve column 27, and the sleeve column 27 drives the stirring paddle blade 28 and the moving disk 26 to rotate. At this time, the sliding column 31 moves along with the rotation of the sliding track 32. At this time, the sliding column 31 pushes the sliding block 33 to move in the sliding groove 30, thereby pushing the pressing plate 34 to squeeze against the inner wall of the filter screen 16. At this time, the extrusion assembly realizes the extrusion process; When the meshing transmission between the half gear 22 and the gear ring 24 ends, the annular rack 23 will immediately mesh and drive the gear ring 24. At this time, the gear ring 24 will rotate in the opposite direction, thereby driving the sleeve column 27 to rotate in the opposite direction, and further driving the stirring paddle blade 28 and the moving disk 26 to rotate in the opposite direction. At this time, the sliding column 31 moves along with the rotation of the sliding track 32. At this time, the sliding column 31 pulls the sliding block 33 to move in the sliding groove 30, thereby pulling the pressing plate 34 to approach the outer wall of the guide block 29. At this time, the extrusion assembly realizes the contraction process; Then pour the slurry into the feed hopper 13. The slurry is stirred back and forth by the stirring paddle blade 28 to promote mixing. The fibers are filtered by the filter screen 16 and removed by the filter cylinder 14, and then gather in the annular cavity formed between the machine shell 10 and the filter cylinder 14, and finally are discharged through the discharge port by the discharge pipe 11.
