In the apparatus disclosed in Patent Document 1, with the spread of OA equipment in recent years, advanced confidential documents, particularly UV ink printed on confidential documents, has a strong adhesive force, and the spiral swirl blade group Entanglement, the rotational force of the spiral swirl wing group must be increased, and even if the rotational force is increased, the rotation eventually stops, and the reproduction includes UV ink entangled in the spiral swirl group. There was a problem that the raw material had to be removed and restarted.
An object of the present invention is to provide a paper stock adjusting device that solves the above problems.

A first invention of the present invention for solving the above-mentioned problems is a paper stock adjusting apparatus as described in claim 1, and is as follows.

A blade for each block, A few inserts are interchangeably mounted, and agitation, washing, compression, dehydration, heat generation, and crushing are performed by high-concentration mixing with kneading metal fittings between kneading blades so that a narrow area and a wide area are roughly divided into two. In this configuration, pressure feeding is performed.

A second invention of the present invention for solving the above-mentioned problems is a paper stock adjusting apparatus as described in claim 2, which is as follows.
When the three cylinders are viewed from the side in a paper material adjustment device for recycled materials made of confidential documents printed with unprocessed UV ink sent by a cylinder press etc. The first cylinder is connected to the third cylinder so that it gradually descends, the raw material inlet is provided at one end of the first cylinder, and the first communication is provided at the other end. A second communication portion is provided on the opposite side of the first communication portion of the second cylinder connected to the first communication portion, and the second communication portion and the third cylinder are connected to each other. A product discharge port is provided on the side opposite to the second communication part, and the regenerated raw material is connected to each cylinder so as to flow in a zigzag manner from the right side to the left side, from the left side to the right side, and from the right side to the left side. Of the three cylinders and at least the first cylinder, the first cylinder is perforated with a large number of small holes. An outer cylinder is provided so as to cover the inner cylinder, and a rotary shaft having independent drive devices penetrating through the three cylinders, and a spiral swirl group is attached to the rotary shaft, A member for preventing entanglement of a rotatable disk-shaped raw material provided with a plurality of notches so as to correspond to the pitch of the swirl blades so as to engage with the swirl blades of the spiral swirl blade group; and The remaining parts of the rotating shaft are obliquely orthogonal to the circumferential direction of the rotating shaft, and adjacent ones are obliquely orthogonally crossed so that the mounting directions are shifted by 180 degrees. High-density mixing with kneading metal fittings between kneading blades so that the kneading blades with blades can be exchanged by inserting multiple pieces into each block in a replaceable manner, and the narrow and wide areas are roughly divided into half. Stir, wash, compress, dehydrate Fever, crushing, is configured to reverse the flow direction of the papermaking raw material to perform pumping.

Since the paper stock adjusting apparatus according to the present invention is configured as described above, the following effects are achieved.
(1) Confidential documents, etc. printed with UV ink that is inserted into the device as it is without being cut into small pieces are entangled with the swirling blades of the spiral swirling blade group especially when water is included in the processing. The swirl vanes are unable to rotate. In order to prevent this, it is possible to prevent the raw material from being entangled with the swirl blade by providing the disk-shaped entanglement preventing member that can freely rotate by engaging with the blade of the spiral swirl blade.
(2) The ratio of fibers coming into contact with the fixed blades of the cylindrical body and the rotating blades of the spiral swirl blade group is reduced, and the emphasis is placed on gently and gently holding the fibers in all directions. Unlike other kneaders, there is less variation in freeness by separating the dust from the fibers without damaging or cutting.
(3) UV ink or the like is neatly separated from the raw fiber, and is refined and dispersed.
(4) The temperature is raised by repeating compression and expansion by forming a narrow area with stagnation metal fittings and a wide area without stagnation metal fittings, and UV ink, wax / hot melt / adhesive foreign matter, etc. are rolled up, and a slit screen. Efficient removal by post-processing.
(5) Since disaggregation is promoted even for difficultly disaggregated and insufficiently disaggregated raw materials, undissolved material is reduced and yield is improved.
(6) The printed UV ink or dust is peeled off from the fiber, and is finely dispersed. For this reason, the measured value of the whiteness of the pulp at the cylinder outlet is displayed low. However, these dusts are removed cleanly by washing with a washer in the next step, and the whiteness is improved.
(7) When hydrogen peroxide is added at the second or third cylinder inlet that has reached high temperature and high concentration, the absorption and penetration of chemicals is promoted by efficient uniform mixing, and a smaller amount of chemicals can be used. The whiteness can be effectively improved.
(8) Since it has high functionality, the current process can be reviewed to simplify the line and reduce wasteful power.
(9) Since the frictional heat between naturally occurring fibers reaches a high temperature (50 to 90 ° C.), no steam is required, leading to a reduction in running cost.
(10) Since the three cylinders are three-dimensionally and compactly arranged, the installation area can be reduced.
(11) The ratio of fibers coming into contact with the fixed blades of the cylinder and the rotating blades of the screw is reduced, and the emphasis is placed on the gentle and gentle squeezing between the fibers. .
(12) The amount of chemicals such as bleaching agents can be reduced.
(13) Friction heat between the regenerated raw material and zigzag pumping in the three cylinders, friction heat with the spiral swirl blade group, collision friction heat with a kneading blade provided with a crushing blade intersecting with the regenerated raw material, A squeeze fitting is provided to form a narrow region and a wide region, and the regenerated raw material in the cylinder is about 50 ° C. to 90 ° C. or more due to frictional heat by alternately going back and forth between these regions and repeating compression and expansion. Because of the heat generated, the chemical permeability increases, the amount of chemical used decreases, and at the same time, the undissolved UV ink and residual carbon mixed in the raw material are separated and decomposed by the crushing blade, so deinking and debonding The agent processing time can be shortened, and the power source can be small and inexpensive.
(14) Recycled raw materials sent by a cylinder press, etc. are gradually stirred, washed, compressed, crushed, dehydrated, heated, and pumped by concentration mixing in a three-stage cylinder, and the flow direction is changed. Achieves remarkable deinking and de-adhesive effects because it is inverted and repeated multiple times.
(15) Instead of the conventional chain drive, the means of directly driving each of the three cylinder motors as a direct-coupled single-shaft type is adopted, and the bearing has been machined so that the motor's power with the optimum capacity can be obtained. It can be fully utilized, there is no worry of chain sound and chain life, and each cylinder has an independent shape, so it is possible to check and maintain a single one for failure inspection and maintenance It is possible to adjust the power of one cylinder and one cylinder depending on the raw material, and the cross crushing blade provided on the kneading blade in the cylinder also changes the mechanism and increases or decreases the number of blades. The ding effect can be enhanced.

  In a paper material adjusting device for recycled raw materials made of confidential documents printed with unprepared UV ink sent by a cylinder press etc., the cylinder cylinder is a perforated with a large number of small holes formed An outer cylinder is provided so as to cover the inner cylinder, a rotary shaft having a drive device penetrating the cylindrical body, a spiral swirl blade group is attached to the rotary shaft, and the spiral swirl blade group A rotating disk-shaped raw material entanglement preventing member having a plurality of notch portions corresponding to the pitch of the swirl blades so as to engage with the swirl blades; Kneading with crushing blades crossed so that the mounting directions intersect with each other so that they are obliquely orthogonal to the circumferential direction of the rotating shaft, and the mounting directions intersect with each other so as to shift the phase by 180 degrees. A blade for each block, A few inserts are interchangeably mounted, and agitation, washing, compression, dehydration, heat generation, and crushing are performed by high-concentration mixing with kneading metal fittings between kneading blades so that a narrow area and a wide area are roughly divided into two. The paper material adjusting device is characterized by carrying out pressure feeding.

  In the conventional technique, steam is injected to heat the raw material, thereby increasing the processing capability. On the other hand, the present invention provides a kneading metal fitting between kneading blades so that a narrow area and a wide area are formed substantially in half, with a screw provided in the first half of the cylinder and a kneading blade provided in the second half. By repeatedly compressing and expanding the raw material alternately moving in this narrow area and wide area, friction between the fibers occurs, and the heat naturally reaches 50 ° C to 90 ° C. The raw materials are 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.

  As another embodiment, the three cylinders are arranged in a substantially triangular shape when viewed from the side so that the flow direction of the regenerated raw material is zigzag for each cylinder, and the first cylinder From the three cylinders, at least the first cylinder is a perforated inner cylinder in which a large number of small holes are formed. An outer cylindrical body is provided so as to cover the body, and a spiral swirl group is attached to a rotary shaft having an independent drive device penetrating each cylindrical body, and further, the remaining part of the rotary shaft is attached to the remaining portion of the rotary shaft. Multiple kneading blades that can be exchanged for each block can be exchanged for each block.The kneading blades are crossed diagonally so that the adjacent ones cross diagonally in the circumferential direction of the rotating shaft. 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 while the raw material moves alternately 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, deinking and de-adhesive treatment can be performed efficiently.

  A spiral swirl blade group (screw) 11 is integrally provided with a suitable length from the raw material inlet 1 side in the cylindrical body 17 that is a cylinder, and the cylindrical rotary shaft 10 is rotatably provided in the cylindrical body. The cylindrical rotary shaft 10 is processed into a polygonal rotary shaft 12 from where the spiral swirl blade group 11 is cut, and a plurality of rotary shafts provided with holes 13 so as to be fitted to the polygonal rotary shaft 12 are provided. The kneading blades 14 that are obliquely orthogonal to each other in the circumferential direction and that are adjacent to each other so as to intersect with each other and are provided with crushing blades in an intersecting manner are inclined at an appropriate angle to alternate It is installed with being inverted. 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 raw material moves alternately between the narrow region and the wide region, the raw material is compressed in the narrow region, expanded in the wide region, and spontaneously heated by friction between the fibers by the squeeze fitting 16, and the temperature is 50 ° C. It will be -90 degreeC.

  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 Therefore, it is possible to perform disaggregation, deinking, and debonding without damaging or cutting the fiber, and separating and dispersing the dust and the adhesive from the fiber.

Further, in the experiment, it was confirmed that the hot melt once melted at a temperature of 90 ° C. or higher, but adhered to the fiber surface and solidified as the temperature dropped below that temperature.
However, in the present invention, the hot melt and the adhesive are peeled off from the fiber and rolled up. Therefore, when operating the paper stock adjusting device of the present invention, the optimum temperature is about 67 ° C. before the hot melt and the sticky material are peeled off from the fiber and rolled up and before the fiber surface starts to melt and solidify on the fiber surface. It was confirmed that It should be noted that the hot melt and the adherent that have been peeled off from the fibers and rolled up are effectively removed by a slit screen in a later step.

  In particular, when confidential documents printed with UV ink are used as a raw material for recycling, it is easier to process when processing the paper as it is or without being cut into small pieces as it is or inserted into a paper material adjusting device. As described above, when moisture is contained in the regenerated raw material, the phenomenon that the regenerated raw material is entangled with the swirl blades of the spiral swirl blade group often occurs. In order to prevent this, a plurality of disk-shaped discs that are provided with a hole at the approximate center of a cylindrical body that is horizontally installed so as to engage with a rotating spiral swirler, and that can be rotated by bearings or the like using this hole. Engage the notch part of the entanglement prevention member formed with the notch part with the swirl blade, and when the swirl blade rotates, the prevention member also rotates, and it gets in the way so as to drop the recycled raw material entangled with the swirl blade This is to prevent this.

  A specific embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, 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.

  As an example, the first cylindrical body is provided with an outer cylindrical body so as to cover a perforated inner cylindrical body in which a large number of small holes are formed (for example, punch metal). Then, raw materials such as confidential documents printed with UV ink or the like fed by a cylinder press or the like through three cylinders including the first cylinder 2 having the perforated inner cylinder are supplied to the raw material inlet 1 (for example, a hopper The first cylinder 2 communicates with the first cylinder 2 on the side opposite to the material inlet 1 of the first cylinder 2 having a perforated inner cylinder with one end of the material inlet 1 provided at one end. A first communication part 3 is provided, and the first communication part 3 is installed in communication with one end of the second cylinder 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.

As shown in FIG. 5 (a), the swirl vanes 18 of the spiral swirl blade group 11 are connected to the swirl vanes 18 from substantially outside the center so as to engage with the spiral swirl blades 18 in a horizontally installed cylinder. An entanglement preventing member 20 having a disc shape and having a plurality of notches 19 is provided so as to be engaged, and the notches 19 are provided so as to match the pitch of the swirl vanes 18. Since 19 is engaged with the swirl vane 18, the swirl vane 18 is engaged with the swirl vane 18 in the cylinder in a horizontal state so that the swirl vane 18 rotates freely as it rotates.
Accordingly, since the notch 19 of the entanglement preventing member 20 is provided so as to surround the swirl vane 18, the regenerated raw material is prevented from being entangled with the swirl vane 18 and dropped to the bottom in the cylinder. It has become.

  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 shafts 8 penetrating through the first to third cylinders are provided so as to be rotationally driven by independent driving devices 9 (for example, geared motors). 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.

  A detailed description of the rotating shaft 5 penetrating each of the first to third cylinders described above is the same as that of the embodiment shown in FIG. 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 the driving device 9 and can be rotated.

  Then, the spiral swirl blade group 11 is appropriately provided integrally with the cylindrical rotating shaft 10 from the raw material inlet 1 side in the first cylindrical body 2 and is further entangled with the swirl blade 18 of the spiral swirl blade group 11. A rotatable disk-shaped entanglement preventing member 20 provided with a plurality of notches 19 that engage with the swirl vanes 18 so as not to entangle the raw material to be attached is provided. The cylindrical rotary shaft 10 is rotatably provided in the cylindrical body, and the cylindrical rotary shaft 10 is processed into a polygonal rotary shaft from a portion where the spiral swirl blade group 11 is cut, and is fitted to the polygonal rotary shaft 12. Kneading with crushing blades crossed obliquely so that the adjacent members intersect each other so as to be obliquely orthogonal to the circumferential direction of a plurality of rotating shafts provided with holes 13 The blades 14 are inclined at an appropriate angle so that the blades 14 are 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 having kneading blades 14 provided with a plurality of intersecting crushing blades can be selected and adjusted according to the raw materials, so that a wide range of raw materials can be removed. It can be applied to ink and de-adhesive treatment.

  In addition, since the block with the kneading blades 14 having the crushing blades in the cross shape is replaceable, it is possible to deink and remove a wider range of materials by preparing several types with different crushing blade mounting angles. It can be applied to adhesive treatment. Further, 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 raw material is not provided with the narrow metal fitting 16 and the kneading metal fitting 16. Each time passing through a wide area alternately, the process of being compressed in a narrow area and expanded in a wide area is repeatedly performed, 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 an intersecting manner is provided in an intersecting manner by inclining at an appropriate angle as illustrated, and the kneading blade 14 is rotated. Therefore, the recycled raw material is crushed into a small lump, and at the same time, one blade of the cross-shaped crushing blade works to move with rotation in the right direction, and the other blade rotates in the left direction. With Since acts to be transferred, 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 collision friction, the temperature rises, separation and decomposition of undissolved ink and residual carbon progress, and when it is finally cleaned, the undissolved ink and residual carbon are washed away with cleaning water and removed. The whiteness will be improved.

  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. When the raw material moves, the compression occurs in a narrow region, and the expansion occurs in a wide region, and the heat spontaneously becomes 50 ° C. to 90 ° C. due to friction between fibers, and UV ink, wax, hot melt, Adhesive foreign matter and the like are rolled up and efficiently removed by post-processing with a slit screen.

  Further, in each of the first to third cylinders, the first half is a screw that pushes the raw material in the first half, and the second half is a sag provided so that the kneading blade 14 is sandwiched between the kneading blades 14 of the cylinder and the screw shaft. Between the metal fittings 16, the fibers of the regenerated raw material are squeezed and rubbed together from the first cylinder 2 to the second cylinder 4, and from the second cylinder 4 to the third cylinder 7. 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.

  In the first and second stages, a dehydration zone is provided. Recycled raw materials of various brands may have variations in dewaterability in the previous process. It is possible to obtain a better and uniform kneading effect by adjusting variations and fluctuations.

  In addition, it is possible to adjust the pressure inside the cylinder body by changing the design, number of sheets, installation angle, etc. of the kneading blade 14 according to the raw material and target quality, and the pressure adjustment damper attached to each cylinder. .

  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.

  Since it is configured as described above, UV ink, adhesives, glue, adhesives, and color vacancies (undissolved ink, residual carbon) that have been considered extremely difficult to remove can be removed with high efficiency. Whatever the type of recycled raw material to be processed, when a certain pressure is applied from the raw material inlet 1 by a cylinder press or the like, stirring is performed in a spiral swirl that penetrates the first cylindrical body 2 Since the rotating shaft 8 provided with the kneading blade 14 provided with the crushing blade intersecting with the blade group 11 is rotated by the driving device 9, the spiral turning blade group 11 forcibly provided the crushing blade in a cross shape. While stirring, compressing and dewatering while squeezing out moisture in the direction of the kneading blade 14, it is heated to 50 ° C to 90 ° C and rotated by alternately moving to the squeeze fitting 16 for narrowing the region and to a wide region. Be It is only being 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 confidential documents printed with UV ink are used as recycled raw materials, the processing is facilitated when processing the paper as it is or without being cut into small pieces as it is or inserted into the paper stock adjusting device. For this reason, when moisture is contained in the regenerated raw material, a phenomenon in which the regenerated raw material is entangled with the swirl blades 18 of the spiral swirl blade group 11 often occurs. In order to prevent this, 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 a plurality of disk-shaped disks that are rotatable such as bearings using this hole. When the notch 19 of the entanglement preventing member 20 formed with the notch 19 is engaged with the swirl vane 18 and the swirl vane 18 rotates, the preventing member 20 also rotates, and the regenerated raw material entangled with the swirl vane 18 is dropped. Thus, it is prevented from getting tangled up.

  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, the ink is pumped to the third cylinder 7 to perform the same action for deinking treatment, and the bleaching action is simultaneously performed by injecting bleaching chemicals.

  Further, each action will be described in detail. Stirring is achieved by rotating the rotary shaft 8 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 moisture that moves with the stirring and compression generated by the rotation of the rotating shaft 8 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 pumping are performed by the pushing force of the inclined surface of the swirl blade by the pressure of the cylinder press and the rotation of the rotating shaft 8 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 8 is eliminated to some extent. In addition, since it is only necessary to make the recycled raw material collide, if one crushing blade is provided with alternately changing directions, the same effect as rotating right and left as a result of rotating can be achieved. Needless to say. As can be seen from these, agitation, washing, compression, dehydration, crushing, heat generation and reversal pumping are performed by rotation of the rotary shaft 8 provided with the spiral swirl blade group 11 and the kneading blade 14 provided with crossing crushing blades. All the functions are performed. Further, a rotatable disk-shaped entanglement prevention provided with a plurality of cutout portions 19 that engage with the swirl vanes 18 to prevent the material to be entangled with the swirl vanes 18 of the spiral swirl blade group 11 from being entangled. The member 20 is provided.

  Then, a kneading blade 14 provided with a crushing blade intersecting with the spiral swirl blade group 11 in order to further improve the degree of deinking, de-adhesive, and de-glue, and the kneading blade 14 are sandwiched between the kneading blades 14. A cylindrical body having a rotating shaft 8 provided with a metal fitting 16 is provided in three stages.

  As described above, in the cylinder of this apparatus, the raw material is → squeezed → compressed → expanded → kneaded → kneaded → steamed by frictional heat → crushing simultaneously with the crushing, the first cylinder is contaminated with water from many small holes. In the process of repeating dehydration, UV ink, adhesive, wax, hot melt, sticking foreign matter, etc. are rolled up, and undissolved ink, residual carbon, etc. are separated and decomposed. Is removed, the whiteness is increased, and the flow direction is reversed, so that the high-concentration mixing improves the entanglement of the fibers, resulting in fewer paper breaks in the product and a significant increase in productivity. did. In addition, a rotatable disk-like entanglement provided with a plurality of notches 19 that engage with the swirling blades 18 to prevent the reclaimed raw material to be entangled with the swirling blades 18 of the spiral swirling blade group 11. The prevention member 20 is provided.

  In addition, since the temperature in the cylinder is increased in a range where frictional heat is generated because the three cylinders are fed in a zigzag manner, a spiral swirl blade group 11 in the cylinder and a crushing blade are provided in an intersecting manner. The kneading blade 14 is sandwiched between the kneading blades 16 and the regenerated raw material and is compressed, heated and steamed at about 50 ° C. to 90 ° C. or higher by frictional heat. ) Increases the penetration rate and makes it even, so that the maximum effect can be achieved with a small amount of chemicals, the amount of chemicals used can be significantly reduced, and the operation cost can be reduced with less power than the processing amount. The machine structure is simple, and not only is it inexpensive, but there are few failures and it can withstand long-term continuous operation.

  In order to perform the deinking and de-adhesive treatment most economically and efficiently, the first and second cylinders are actively dehydrated and the third cylinder is subjected to bleaching chemicals (for example, caustic). When soda + hydrogen peroxide) was injected, and dehydration and chemical injection bleaching were performed, even if hot melt granules were mixed, as a result of testing, it was possible to sufficiently bleach .

  It can be used for slow pressure deinking treatment equipment and paper stock adjustment equipment for all recycled materials.
