Specialized in heat generation, crushing and pumping The palm of the raw material palm to a stock adjustment device as a raw material.

  In the conventional technique, steam is injected to heat the raw material, thereby increasing the processing capability. On the other hand, in the present invention, when refining palm oil from palm palm, the fiber is long and strong in order to adjust the stock using the discharged residual fiber as a recycled raw material. A crusher with a disk-like wrapping prevention member cut to a length of 0 cm, a small amount of water is added to the cut residual fiber, and a spiral swirling blade can be freely rotated; As shown in FIG. 7, a rotary body 8 with a scraping blade is provided at the discharge port of three cylindrical bodies, and further, as shown in FIG. 4, the spiral swirl blade (screw 27) can be freely rotated. A disk-shaped member 31 for preventing wrapping is provided, a screw 27 is provided in the first half of the cylinder, and a kneading blade 14 provided with a crushing blade is provided in the second half, and kneading is performed so that a narrow area and a wide area are formed substantially in half.

As with the above, between the kneading blades so that a narrow area and a wide area are formed approximately in half. By providing a metal fitting and repeatedly compressing and expanding the raw material alternately moving between this narrow area and wide area, friction between the fibers occurs, and the heat naturally reaches 50 ° C to 90 ° C. The raw material is stirred, washed, compressed, dehydrated, exothermic (heated and steamed), crushed and pumped very well. Furthermore, a rotatable disk-shaped anti-tangler member provided with a plurality of cutout portions that engage with the swirl blade that prevents the raw material to be entangled with the spiral swirl blade group is provided. is there.

  Moreover, the invention of the present invention does not require a large power source, the flow direction of the papermaking raw material can be reversed for each cylinder, and crushing is performed with a kneading blade provided with crossing crushing blades, so steam is injected. In addition, there is no need to do this, and the processing is performed efficiently without residual fibers getting tangled.

In the present invention, the residual fiber discharged when palm oil is purified from palm palm is pulped as a recycled raw material.
As shown in FIG. 1, it demonstrates based on the one specific flowchart which pulps the residual fiber discharged | emitted after the palm oil refinement | purification of palm palm as a recycled raw material.
First, the pre-treatment of the pulping process is performed, and the residual fiber is cut to a length of about 2.5 to 3.0 cm by a conventionally known cutting machine 21. The cut fibers are crushed by the crusher 23 through the first conveyor 22, and the crushed fibers are fed into the high-concentration digester through the second conveyor 24 to digest at a high concentration. The treated fibers are roughly selected, washed, carefully selected, beaten, and then subjected to a bleaching step to be pulped.
Since the palm palm residue fibers are long and strong, the spiral swirl wings (hereinafter referred to as screws) get entangled and the material discharged from the cylinders becomes hard, making it difficult to enter the next stage. However, it has been extremely difficult with the conventional paper material adjusting device.

  The present invention is an invention that solves this problem. First, as a pre-treatment in the pulping process, a long palm insulator residue fiber is cut to a length of about 2.5 to 3.0 cm by a cutting machine. This cut fiber is supplied to the crusher, a small amount of water is poured into it, it is crushed, the mud and foreign matter adhering to the fiber is separated, and the fiber is rubbed into a shape in which the alkaline cooking solution can easily penetrate. Cut. And it permeates efficiently, adding a suitable quantity of an alkali agent to the fiber raw material of the palm palm roughly crushed with this crusher, and carries out high concentration cooking continuously. The main heat source at this time is generated by a mechanical action, and can be pulped in a very short time as compared with the conventional processing time from the input of the fiber raw material to the discharge.

Next, the crusher 23 will be specifically described with reference to FIGS. 2, 3, and 4. As a preliminary operation, the palm fiber residue fibers cut to a length of about 2.5 to 3.0 cm are 1 Using a shaft crusher, cut and crush to a substantially constant size. Thereby, the post-processing load can be reduced.
Since the residual fiber is strong and long, the tip end portion 28 of the screw 27 provided on the rotary shaft 26 is cut into a Y-tip 29 to improve the fiber catching and easy to carry. In other words, because the palm palm residue fiber is long and strong, it does not collapse into a hard block shape when entering each next process, it does not get into the cylinder and is caught, and it can not be captured well between the screw pitch of the next process As a result, a bridging phenomenon occurs, and as a result, the portion becomes a brake, causing an overload on the device and a phenomenon of stopping.
In order to solve this problem, the block can be broken and the bridge phenomenon can be eliminated by cutting the screw tip into a Y-shaped tip 29.

Further, since the residual fiber is long, a phenomenon of winding around the screw 27 and a co-rotation phenomenon that the fiber does not advance only by rotating with the screw occur. As a means for solving this problem, it is conceivable to cut the edge of the screw 27 and insert skewer blades. However, since the force for pushing the regenerated material is lost, the regenerated material (palm palm residue) to be entangled with the screw 27 is lost. As shown in FIGS. 3 and 4, a disk-shaped entanglement prevention that is freely rotatable by the rotation of the screw 27 provided with a plurality of notch portions 30 that engage with the screw 27 as shown in FIGS. The member 31 for use is provided.
As shown in FIG. 4, the screw 27 of the spiral swirl blade group includes a plurality of disks in a disc shape so as to engage with the screw 27 from substantially the outside of the center so as to engage with the screw 27 in a horizontally installed cylinder. An entanglement preventing member 31 having a single notch 30 is provided. The notch 30 is provided to match the pitch of the screw 27, and the notch 30 is engaged with the screw 27. Therefore, the screw 27 is engaged with the screw 27 in the cylinder in a horizontal state so as to freely rotate following the rotation of the screw 27.
Therefore, since the notch 30 of the entanglement preventing member 31 is provided so as to surround the screw 27, the regenerated raw material is prevented from being entangled with the screw 27 and dropped to the bottom of the cylinder. Yes.

Next, a high concentration cooking apparatus will be described with reference to FIGS.
From the raw material inlet 1 side in the first cylindrical body 2 which is a cylinder, a spiral swirl blade group 11 is integrally provided with an appropriate length on a rotary shaft 10 as shown in FIG. The rotary shaft 10 is formed into a polygonal rotary shaft 12 from a cut portion of the spiral swirl blade group 11, and a plurality of holes are provided so that the polygonal rotary shaft 12 can be fitted. The kneading blade 14 provided with the crushing blades in a crossing manner so as to be obliquely orthogonal to the circumferential direction of the rotation axis and crossing adjacent ones is inclined at an appropriate angle. It is attached by reversing every sheet alternately. In order to form a narrow region, a greasing metal fitting is provided so that the kneading blade is sandwiched between the kneading blades in approximately half of the circumference, and a large region is not provided in almost half of the remaining circumference. To form.

  Since the palm fiber residue fiber raw material moves alternately between the narrow region and the wide region, it is compressed in the narrow region, expanded in the wide region, and is naturally heated by the friction between the fibers by the squeeze fitting 16. The temperature is from 50 ° C to 90 ° C.

  And, under the action of conveyance → compression → expansion → agitation → squeeze → kneading → kneading → heating / steaming, disaggregation, deinking, de-adhesive, miniaturization and dispersal of foreign matter progress, and mechanical fiber cutting Can be pulped without damaging the fibers.

  In particular, as shown in FIG. 8, since the residual fiber after refining palm oil from palm palm is long and strong, the regenerated raw material is applied to the swirl blades 18 of the spiral swirl blade group 11 having the same function as the crusher 23. Intertwining phenomena often occur. In order to prevent this, as shown in FIG. 4, a hole is provided at the approximate center of a cylindrical body that is horizontally disposed so as to be engaged with the rotating spiral swirl wing 18 and rotated by a bearing or the like using this hole. When the notch 30 of the entanglement preventing member 31 formed with a plurality of disc-shaped notch parts 30 is engaged with the screw 27 and the screw 27 is rotated, the entanglement preventing member 31 is also rotated. This prevents the entangled recycled raw material from getting tangled by dropping it.

  A specific embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 5 to 7, the first cylindrical body is arranged so as to have a substantially triangular shape when viewed from the side. To be gradually lowered to connect to the third cylinder.

  The first cylinder is provided with an outer cylinder so as to cover a perforated inner cylinder in which a large number of small holes are formed (for example, punch metal). And the recycled raw material which is the residual fiber of palm palm sent by a cylinder press etc. by three cylinders including the 1st cylinder 2 which has this perforated inner cylinder from raw material input 1 (for example, hopper etc.) The first communicating portion that communicates with the first cylinder 2 on the opposite side of the material inlet 1 of the first cylinder 2 having a perforated inner cylinder that is provided with one end of the material inlet 1. 3, and the first communication part 3 is installed in communication with one end of the second cylindrical body 4. At this time, the first cylinder 2 has a perforated inner cylinder made of a material such as stainless steel in which a large number of small holes are formed (for example, punch metal). Between the kneading blades 14 and the kneading blades 14 attached to the spiral swirl blade group 11 on the rotating shaft, and a narrow region and a wide region of the cylindrical body 2 can be formed substantially in half. By providing the squeezing metal fitting 16, stirring, washing, compression, heat generation, crushing, and pressure feeding are performed, and at the same time, dehydration is actively performed from a large number of small holes in the inner cylinder, and this dehydrated dirty water is U-shaped. It collects in the outer cylinder and drains from the drain. Further, a second communication part 5 for communicating with the third cylinder 7 is provided on the side opposite to the first communication part 3 communicating with the second cylinder 4, and the second communication part 5 is the third communication part 5. A product discharge port 6 provided with a pressure regulating valve is provided in the third cylinder 7 on the side opposite to the second communication part 5 of the third cylinder 7. It has been.

  When the communication portions of the first to third cylinders flow from the first to second and second to third cylinders, the flow direction is reversed each time. The rotating shaft 10 penetrating through each of the first to third cylinders is provided so as to be rotationally driven by an independent driving device (for example, a geared motor). In addition, the arrangement of the first to third cylinders is not limited to the one shown in the figure when viewed from the side, and can be designed in various ways depending on the arrangement of the building and related equipment so as to be an equilateral triangle. Needless to say. Furthermore, it goes without saying that the attachment positions of the raw material inlet 1, the communication portions 3 and 5, and the product outlet 6 can be appropriately arranged in consideration of efficiency.

  In the above description, only the first cylindrical body 2 has a perforated inner cylindrical body in which a large number of small holes are formed. However, the second and third cylindrical bodies have the same large number of small cylinders. It goes without saying that it is possible to have a perforated inner cylinder in which holes are formed. Needless to say, in this case, each of the perforated inner cylinders is covered with an outer cylinder.

  When the rotation shaft 10 penetrating each of the first to third cylinders is described in detail, the same shaft as that of the embodiment shown in FIG. 5 is used. A first cylinder 2 having an inner cylinder, a second cylinder 4 not having a perforated inner cylinder with a small hole, and a bearing (not shown) provided in the third cylinder 7 Thus, one end is supported and the other end is supported by a driving device so that it can rotate.

  Then, the spiral swirl blade group 11 is integrally provided with an appropriate length on the rotary shaft 10 from the raw material inlet 1 side in the first cylindrical body 2, and further, as shown in FIGS. The connection part of the 2nd cylinder 4 from the cylinder 2 and the 3rd cylinder 7 from the 2nd cylinder 4, ie, the reproduction | regeneration raw material of the residual fiber discharged | emitted from the 1st cylinder 2, is the next process. When a fixed amount is charged into the second cylinder 4, since the recycled material is long and hard, it becomes hard and difficult to enter the next process, so each cylinder (at least one cylinder depending on the recycled material) By providing a rotating body with a scraping blade provided with a plurality of fang-shaped blades in the vicinity of the discharge port, scraping is carried out while cutting out, and a fixed amount is supplied to the next process, thereby stabilizing the operation. The rotary shaft 10 is rotatably provided in the cylindrical body, so that the rotary shaft 10 can be machined into a polygonal rotary shaft from where the spiral swirl blade group 11 is cut, and can be fitted to the polygonal rotary shaft 12. A kneading blade 14 provided with crushing blades in an intersecting manner so as to be obliquely orthogonal to the circumferential direction of a plurality of rotating shafts provided with a perforation, and so as to intersect with each other. Inclined at an appropriate angle, each sheet is alternately reversed and attached. And the squeeze fitting 16 is provided between the kneading blades so that the narrow region and the wide region are substantially divided into half. In addition, each block is attached to the polygonal rotation shaft 12 in an independent manner. The block having the kneading blade 14 provided with the above-described crushing blades attached to the outermost end side is fixed by a screw-in type 15. The number of blocks with kneading blades 14 provided with a plurality of intersecting crushing blades can be selected and adjusted according to the raw material, so it can be applied to a wide range of raw materials. can do.

  In addition, since the block with the kneading blade 14 provided with the crushing blades in the cross shape is replaceable, it can be applied to a wider range of recycled materials by preparing several types with different crushing blade mounting angles. Can do. Furthermore, by providing the kneading metal fitting 16 only in a substantially half-divided region so that the kneading blade 14 is sandwiched between the kneading blades 14, the reclaimed raw material is provided with a narrow area where the kneading metal fitting 16 is provided, and the kneading metal fitting 16. Each time it passes through a wide area, the process of compressing in a narrow area and expanding in a wide area is repeated, so that the heat naturally becomes 50 ° C to 90 ° C due to friction between fibers. In addition, the crushing blade provided on the kneading blade 14 provided with the crushing blades in the cross shape is inclined at an appropriate angle as shown in the figure and is provided in the cross shape. Since it rotates, the recycled raw material is crushed into small blocks, and at the same time, one blade of the crossed crushing blade works to move with rotation in the right direction, and the other blade in the left direction Rotate Since acts to be transported I, every time the reproduction material passes through portions of the kneading blades, occurs conditions such as untwisting, accompanied by rotation, right row, collides with left row. Due to the impact friction, the temperature rises, decomposition progresses, and when it is finally cleaned, the whiteness is increased as a result.

  Further, since the kneading blades 14 provided with a plurality of intersecting crushing blades are inclined at a certain angle and are alternately inverted one by one, the recycled raw material flows through each cylinder. The acting force in the thrust direction alternates between the right and the left by the kneading blade 14 provided with the crushing blades at each intersection, so that they are offset and the regenerated raw material generates a very smooth flow.

  Between the kneading blades provided in the cylinder, the squeeze metal fitting 16 is provided so as to form a narrow region so that it is substantially divided into half, so that the other half becomes a wide region, and this narrow region and the wide region are alternately arranged. The regenerated raw material moves to the inside, so that compression occurs in a narrow region and expansion occurs in a wide region, and the heat spontaneously becomes 50 ° C. to 90 ° C. due to friction between fibers, and efficient pulping is achieved. Is.

  Further, in each of the first to third cylinders, the first half is provided so that the screw pushes the recycled material, and the latter half is provided so that the kneading blade 14 is sandwiched between the kneading blades 14 of the cylinder and the screw shaft. The reclaimed raw material fibers are squeezed and rubbed between the squeeze fittings 16, and the rotating shaft 10 is moved from the first cylinder 2 to the second cylinder 4 and from the second cylinder 4 to the third cylinder 7 each time. Proceed while changing the direction of rotation. Each cylinder is a single direct drive type and can be controlled independently. Accordingly, it is possible to make appropriate adjustments corresponding to the fluctuations of the raw materials and adapted to the target product.

  It is possible to adjust the pressure inside the cylinder by changing the design, number of pieces, installation angle, etc. of the kneading blade 14 and the pressure adjustment damper attached to each cylinder according to the recycled material and target quality. is there.

  It should be noted that the water injection port, the medicine injection unit, and the first, second, and third cylinders have dehydrated water (this is dirty water such as processed ink) so that water can be poured into each cylinder. It is natural that a drainage part provided with a filter or the like for draining is not shown.

  Due to the above-described configuration, when a recycled raw material made of palm palm, which has heretofore been difficult to pulp, is introduced from the raw material inlet 1 while applying a certain pressure by a cylinder press or the like, Since the rotary shaft 10 provided with a kneading blade 14 provided with a crushing blade intersecting with a spiral swirl blade group 11 penetrating through one cylindrical body 2 is rotated by a driving device, the spiral swirl blade group 11 By stirring, compressing and dewatering while squeezing moisture in the direction of the kneading blade 14 with the crushing blades provided in a crossing manner, and simultaneously moving to the wide area with the squeeze fitting 16 for narrowing the area , Heated to 50 ° C. to 90 ° C., rotated, crushed and pumped.

  The regenerated raw material pumped with stirring, dehydration, compression, and swelling is discharged from a large number of small holes in the outer cylinder and drained from a drain outlet. At the same time, it is heated by the friction generated between the perforated inner cylinder of the first cylinder 2, the spiral swirl blade group 11, and the kneading blade 14 provided with the crushing blades in a crossing manner, and then a plurality of kneading blades Since the attachment angle of the cross-shaped crushing blade provided in 14 is inclined and alternately reversed and attached, the recycled material is crushed while swinging left and right, and the raw material is narrow and wide. While being heated by the alternating movement, the second cylinder 4 is fed under a certain degree of air pressure.

  In particular, when processing palm palm residue fiber as a recycled material by inserting it into the paper stock adjusting device, if the recycled material contains moisture for easy processing, the recycled material will harden and enter the next process. The rotator with fang-shaped blades is placed in the vicinity of the discharge part of the previous process that enters the next process from the previous process. , The operation can be stabilized.

  Then, by reversing this and repeating the same action as that performed by the first cylinder 2 in the second cylinder 4, the stirring, dehydration, compression, warping, heat generation, and crushing are performed again.

  Further, each action will be described in detail. Stirring is achieved by rotating the rotary shaft 10 provided with a kneading blade 14 provided with a crushing blade intersecting with the spiral swirl blade group 11 in the cylinder.

  In the cleaning, the dirt is dissolved in the water that moves with the stirring and compression generated by the rotation of the rotary shaft 10 provided with the kneading blade 14 provided with the crushing blade in a crossing manner with the spiral swirl blade group 11 in the cylinder, In particular, in the case of the first cylinder 2, the cleaning action is exerted more strongly by being positively removed from the perforated inner cylinder having a large number of small holes.

  The compression and the pumping are performed by the pressure of the cylinder press and the pushing force of the inclined surface of the swirl blade 18 by the rotation of the rotating shaft 10 provided with the spiral swirl blade group 11.

  Dehydration is substantially achieved by the action of compression and pumping. Moreover, the dewatered portion is discharged from the small holes of the first cylindrical body 2 having a perforated inner cylinder formed with a large number of small holes, and further discharged through the outer cylindrical body.

  Heat generation from 50 ° C. to 90 ° C. is caused by friction between fibers by repeatedly compressing and expanding the raw material by alternately moving the squeeze fitting 16 provided to make a narrow region and the wide region where the squeeze fixture 16 is not provided. At the same time, the frictional heat generated by the three cylinders being pumped in a zigzag manner, the frictional heat generated between the recycled material and the spiral swirl blade group 11 in the cylinder, the supply pressure and the discharge port of the material Friction heat due to high pressure in the cylinder caused by pressure adjustment in the cylinder occurs, and furthermore, friction heat generated when crushing by rotation of a kneading blade 14 provided with a plurality of intersecting crushing blades and crushing in an intersecting manner Since the blade is provided, the recycled material tries to move to the right with one crushing blade and to the left with the other crushing blade. Frictional heat is generated by repeated collisions Is shall.

  Further, when the returning action occurs, the thrust load of the rotating shaft 10 is eliminated to some extent. In addition, since it is only necessary to make the recycled raw material collide, if one crushing blade is alternately changed in direction, the same effect as rotating right and left can be obtained by rotating. Needless to say. As can be seen from these, agitation, washing, compression, dehydration, crushing, heat generation and reverse pumping are carried out by rotation of the rotary shaft 10 provided with the spiral swirl blade group 11 and the kneading blade 14 provided with intersecting crushing blades. All the functions are performed. Furthermore, it is difficult to enter the next process because the recycled raw material is hardened by providing a rotating body provided with fang-shaped blades in the vicinity of the discharge part of the previous process that enters the next process from the previous process. It is possible to stabilize the operation by scraping the recycled material while cutting it out and feeding it to the next process in a fixed amount.

  As described above, the temperature in the cylinder is increased in the range in which frictional heat is generated because the three cylinders are fed in a zigzag manner, and at the same time, the spiral swirl blade group 11 in the cylinder is crushed in an intersecting manner. Since the kneading blade 14 provided with the blade, the kneading blade 14 and the regenerated raw material are compressed, heated and steamed at about 50 ° C. to 90 ° C. or higher, the chemical (bleaching liquid) penetration rate Because it increases and becomes uniform, the maximum effect can be achieved with a small amount of chemicals, the amount of chemicals used can be significantly reduced, operation with less power than the processing amount is possible, and running costs are reduced, Not only is the machine structure simple, it is inexpensive, but there are few failures and it can withstand long-term continuous operation.

  It can be used for a paper stock adjusting device for all recycled materials.
