[0002] Paper is a very common commodity in our daily lives. Paper processing plants have many production processes. The better the quality of the paper, the higher the requirements for paper processing technology and materials. During paper processing, the pulp contains a lot of wastewater as production progresses. Separators are generally used in production to dewater the contaminated pulp. When contaminated pulp needs to be treated, it must first be separated to remove the solids before further environmentally friendly processing can proceed. However, in most separators, the pulp tends to adhere to the filter screen during separation, thereby reducing the separation effect and efficiency. Cleaning is required to restore the separation efficiency. To address this problem, the inventors have proposed an anti-clogging, clean pulp separation device for papermaking. Utility Model Content

[0018] A positioning shaft 49 is fixedly connected to the top of the inner end of the top shell 61 near the outer ring, and the lifting shaft 47 is slidably connected to the positioning shaft 49.

[0019] By adopting the above technical solution, a positioning shaft 49 is set at the top of the inside of the top shell 61 to assist the lifting shaft 47 in lifting.

[0020] A main motor 44 is installed at the center of the bottom of the outer cylinder 4. The output end of the main motor 44 passes through the outer cylinder 4 and is fixedly connected to the separation cylinder frame 42. An auxiliary motor 59 is installed at the center of the top of the top shell 61. The output end of the auxiliary motor 59 passes through the top shell 61 and is fixedly connected to the rotating shaft 5.

[0021] By adopting the above technical solution, the main working motor 44 is driven, thereby fixing the fixedly connected separation cylinder frame 42 and the auxiliary working motor 59, which in turn allows the fixedly connected rotating shaft 5 to rotate.

[0022] A vertical plate 52 is fixedly connected to the bottom of the top shell 61 near the center. A worm gear 53 is rotatably connected to the front end of the vertical plate 52.

[0032] Working principle: When using this device, the top cover 45 is first raised by the working electric cylinder 22, and then pulp and clean water are put in (adding clean water can reduce contaminants in the pulp raw material during separation). Then the main motor 44 and the auxiliary motor 59 are activated, so that the fixedly connected rotating shaft 5 drives the stirring paddle 46 to rotate, realizing the mixing of clean water and pulp raw material. The main motor 44 drives the separation cylinder frame 42 to rotate to achieve the separation effect. During the separation rotation, the pulp raw liquid will pass through the screen 43 for centrifugal solid-liquid separation. The water in the pulp is discharged into the separation outer cylinder 4 through the screen 43. Finally, the collection cylinder is set on the placement plate 3, and the valve on the water outlet pipe 41 is opened to achieve the effect of liquid discharge. When the rotating shaft 5 rotates, the worm gear 51 drives the worm wheel 53 to rotate. Then, with the cooperation of the eccentric wheel 54, connecting rod 58, connecting plate 55, and adapter block 6, the lifting shaft 47 can move up and down repeatedly under the action of the positioning shaft 49. This can drive the fixedly connected rubber comb teeth 48 to move back and forth on the screen 43, avoiding the pulp raw material inside the separation cylinder 42 from adhering and accumulating on the screen 43 during centrifugation, thereby improving the separation effect.
