Description

Technical Field

[0001] The present invention relates to the field of pulp preparation and processing, and in particular to a fluid hybrid fine cutting machine system and a processing method for pulp preparation. Background Art

[0002] During papermaking, the pulp after cooking, screening and bleaching needs to be refined by a pulper. The pulp after being refined by the pulper has higher elasticity and plasticity, so that the produced paper can meet the expected quality indicators. Therefore, the pulper is an indispensable equipment in papermaking.

[0003] Chinese invention patent CN115852726A discloses a waste paper pulping machine and refining method, comprising a frame, an outer grinding drum, a middle grinding drum, an inner grinding drum, an outer grinding drum drive mechanism, and an inner drum drive mechanism. The outer grinding drum is rotatably mounted on the frame, the middle grinding drum is disposed within the outer grinding drum, and the inner grinding drum is rotatably mounted within the middle grinding drum. The outer grinding drum drive mechanism is transmission-connected to the outer grinding drum, and the inner drum drive mechanism is transmission-connected to the inner grinding drum. The outer grinding drum rotates in the opposite direction to the inner grinding drum. Pulp first enters the inner grinding drum, where beating blades first break up large particles in the pulp, preventing jamming during refining. This ensures a smooth refining process, reduces wear, and increases service life. Pulp then flows between the inner and middle grinding drums for coarse grinding, and then between the middle and outer grinding drums for fine grinding. This simultaneous coarse and fine grinding of the pulp results in a more uniform pulp and better refining effect. Two sets of refiners are not required, saving space and reducing production costs. The large grinding area and high refining efficiency are achieved.

[0004] The above scheme improves the grinding effect of the pulp by grinding in two stages. However, during the grinding process, a large amount of paper scraps will remain between the grinding plates due to the stirring and conveying of the pulp for grinding. Due to the slow flow of the liquid, the paper scraps cannot flow with the liquid and will remain in the gaps, thereby affecting the grinding efficiency. In addition, the pre-crushing effect of the pulp is not good, and a large amount of pulp flows with the liquid and cannot be crushed to the maximum extent. At the same time, the grinding size of the pulp cannot be controlled.

[0005] Therefore, it is necessary to provide a fluid hybrid fine-crushing machine system and processing method for pulp preparation to solve the above technical problems. Summary of the Invention

[0020] This solution also provides a method for preparing pulp, comprising the following steps:

[0021] S1. First, the pulp is passed into the inner grinding cylinder and transported to the top of the connecting plate through the conveying assembly.

[0022] S2. The connecting plate is driven upward by the transmission member, and the pulp passes through the connecting plate. As the connecting plate descends, the pulp under the connecting plate is squeezed, causing the pulp to quickly pass through the support frame. The pulp is crushed by the crushing assembly inside the support frame, and as the connecting plate is squeezed, the pulp can quickly flow into the second gap.

[0023] S3.

[0026] 2. The pulp flows into the bottom of the connecting plate through the first circulation groove. When the connecting plate descends, the sealing baffle at the bottom of the connecting plate rises due to resistance to seal the first circulation groove. As a result, when the connecting plate descends, the pulp between the inner grinding cylinder and the connecting plate is pushed downward, thereby increasing the pressure and rushing into the second gap, thereby quickly pushing the pulp to move in the second gap. By increasing the flow rate of the liquid, the pulp residue that may remain between the second spiral plate and the third spiral plate can flow quickly, thereby improving the fluidity of the pulp.

[0052] During specific implementation, when the pulp is introduced into the inner grinding cylinder 3 through the liquid inlet valve, the pulp is squeezed to the second gap through the pulp outlet groove 303 opened on the outside of the inner grinding cylinder 3 by the conveying component, and then the first motor 705 is started, and the output shaft of the first motor 705 drives the mounting plate 702 to rotate, and the mounting plate 702 drives the upper support cylinder 701 to rotate through the hydraulic telescopic rod 703, thereby rotating the middle grinding cylinder 2, so that the second spiral blades 201 on both sides of the middle grinding cylinder 2 squeeze and crush the pulp, so that the pulp is conveyed upward to the first gap through the second gap. It is worth noting that the spiral directions of the two second spiral blades 201 are set in opposite directions, and the pulp is finally conveyed to the inside of the collecting frame 9 through the second gap and the first gap, thereby improving the pulp grinding efficiency.

[0053] Furthermore, the hydraulic telescopic rod 703 can be activated to push the upper support cylinder 701 upward, thereby adjusting the gap between the second spiral piece 201 outside the middle grinding cylinder 2 and the outer grinding cylinder 1 and the inner grinding cylinder 3, thereby adjusting the size of the pulp grinding.

[0054] Example 2: Figures 4 to 6 As shown, a plurality of first circulation grooves 501 for pulp circulation are provided on the outer side of the connecting plate 5, and sealing baffles 502 for covering the first circulation grooves 501 are provided on the upper and lower sides of the connecting plate 5. A sliding rod 503 is fixedly connected between the two sealing baffles 502, and the sliding rod 503 passes through the connecting plate 5 and is slidably connected to the connecting plate 5. The sealing baffle 502 provided on the upper part of the connecting plate 5 is fixedly connected to the side of the connecting plate 5 close to the connecting plate 5.

[0055] The conveying assembly includes a rotating rod 4 that passes through the outer grinding cylinder 1 and extends to the inside of the inner grinding cylinder 3. The rotating rod 4 is rotatably connected to the outer grinding cylinder 1. A spiral conveying blade 401 is fixedly connected to the outside of the rotating rod 4.

[0056] The transmission parts include multiple pushing cylinders 801 fixedly connected to the top of the connecting plate 5, and multiple pushing cylinders 801 are equipped with reciprocating screws 802 inside.

When the rotating rod 4 rotates, one end of the rotating rod 4 is fixedly connected to the transmission ring gear 804, and then the transmission ring gear 804 rotates to drive multiple meshing transmission gears 803 to rotate, and the transmission gear 803 drives the reciprocating screw rod 802 to rotate, and then the reciprocating screw rod 802 drives the outer pushing cylinder 801 to rise. When the pushing cylinder 801 rises, it drives the connecting plate 5 fixedly connected to the bottom to rise. When the connecting plate 5 rises, A contact column 504 is fixedly connected to the bottom of the sealing baffle 502 on the upper part of the connecting plate 5, so that the pulp flows into the bottom of the connecting plate 5 through the first circulation groove 501. When the connecting plate 5 descends, the sealing baffle 502 at the lower part of the connecting plate 5 rises due to resistance to seal the first circulation groove 501, so that when the connecting plate 5 descends, the pulp between the inner grinding cylinder 3 and the connecting plate 5 is pushed downward, thereby increasing the pressure and rushing into the second gap, thereby quickly pushing the pulp to move in the second gap. By increasing the flow rate of the liquid, the pulp residue that may remain between the second spiral plate 201 and the third spiral plate 301 can flow quickly, thereby improving the fluidity of the pulp.

The inner walls of the gear ring 603 and the second outer gear ring 605 are fixedly connected with multiple crushing pieces 6031, the top of the fixed cover 601 is rotatably connected with the first gear 604, the first gear 604 is meshed with the multiple first outer gear rings 603, the bottom of the first gear 604 is fixedly connected with the third gear 607, the outer sides of the multiple second outer gear rings 605 are meshed with second gears 606, the multiple second gears 606 are meshed with the third gear 607, and the second gear 606 is rotatably connected to the bottom end of the fixed cover 601.

[0060] In a specific implementation, when the pulp flows into the space between the connecting plate 5 and the bottom end of the inner grinding cylinder 3 through the first circulation groove 501, when the connecting plate 5 descends, the fixed cover 601 also descends with the connecting plate 5. Since a plurality of second circulation grooves 602 are provided on the outside of the fixed cover 601, the pulp passes through the second circulation grooves 602, the first outer gear ring 603 and the second outer gear ring 605. When the connecting plate 5 moves up and down, the upper support cylinder 701 also keeps rotating. The transmission rod 609 drives the slide groove and the slider to drive the transmission cylinder 608 to rotate, and the transmission cylinder 608 drives the third gear 607 and the first gear 60 4 rotates, and then the first gear 604 drives the first outer gear ring 603 to rotate, the third gear 607 drives the second gear 606, and the second gear 606 drives the second outer gear ring 605 to rotate, so that the first outer gear ring 603 and the second outer gear ring 605 rotate in two directions, and then the crushing pieces 6031 inside the first outer gear ring 603 and the second outer gear ring 605 crush the pulp and pre-treat the pulp before grinding, and the stirring plate 610 outside the transmission cylinder 608 stirs the pulp to fully mix the paper scraps with the liquid, thereby ensuring the fluidity of the pulp during grinding and improving the grinding efficiency.
