Description

Technical Field

[0001] The invention relates to the technical field of pulp preparation, in particular to a pure physical pulping process of coniferous forest and Tencel. Background Art

[0002] Coniferous wood (the starting material) and Tencel (recycled material) are crushed and pulped. Tencel is a man-made fiber, while coniferous wood is the starting material for papermaking. The physical pulping process loosens the wood fibers by mechanically shearing and beating the logs. The two are then mixed and pulped to produce higher-quality pulp. The entire physical pulping process does not rely on chemicals, is environmentally friendly and sustainable, and is suitable for producing high-quality paper and specialty paper products.

[0003] Since the difficulty of crushing the two is different, if they are stirred and crushed at the same time, the Tencel fiber will be over-crushed and the coniferous forest fiber will be insufficiently crushed, so separate pulping is performed. However, in the existing separate pulping process, after the two are crushed separately, the crushed coniferous forest wood fiber and Tencel fiber need to be added to the mixing equipment respectively, and then the mixed pulping work is performed.

[0004] The pulping work is carried out in this step-by-step manner, resulting in the discontinuity of the entire mixed pulping process, making the mixed pulping efficiency low; and the usual crushing and breaking up is carried out by a single crushing knife at the bottom. During the long-term crushing and breaking up work, the coniferous forest wood fiber or Tencel fiber is easily rotated in a vortex manner, resulting in insufficient shear force on the coniferous forest wood fiber or Tencel fiber, affecting the crushing effect.

[0045] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] like Figure 1 and Figure 2 As shown, a pure physical pulping process of coniferous forest and Tencel includes the following steps: S1. Raw material preparation: selecting high-quality coniferous forest wood and Tencel as raw materials to ensure the purity and quality of the raw materials.

[0047] S2. Chipping and screening: Chipping coniferous wood and removing impurities and dust through screening.

[0048] S3. Physical treatment: Use purely physical methods, such as mechanical extrusion and steam explosion, to soften and separate the raw materials to reduce mechanical damage to the fibers.

[0049] S4. Mixing and pulping: The processed coniferous forest wood fibers and Tencel are crushed and dispersed using a mixing device and then mixed in a certain proportion to obtain high-quality pulp.

[0050] S5. Subsequent processing: The pulp is bleached and dried as needed to meet the production requirements of different products.

[0051] S6. Packaging and storage: The processed pulp is sliced, packaged, and properly stored for use.

[0052] The mixing equipment involved in the above-mentioned step S4 includes a mixing box 1, and two left-right symmetrical loading barrels 2 are fixedly connected to the upper surface of the mixing box 1. The upper surfaces of the two loading barrels 2 are jointly provided with a first driving mechanism 3, and the bottom ends of the loading barrels 2 are rotatably connected to a double-headed crushing blade shaft 6. The mixing equipment also includes a second driving mechanism 7 for driving the double-headed crushing blade shaft 6 to rotate on the loading barrel 2. The second driving mechanism 7 is arranged on the mixing box 1. The mixing equipment also includes a sealing mechanism 5 for controlling the discharge of raw materials in the loading barrel 2. The sealing mechanism 5 is arranged on the outer circumferential surface of the loading barrel 2. The mixing equipment also includes a processing mechanism 4 for assisting in crushing and breaking up the raw materials inside the loading barrel 2. The processing mechanism 4 is arranged on the mixing box 1.

[0053] like Figure 3 As shown, the first driving mechanism 3 includes a driving member 32 arranged on the loading bucket 2, and an I-shaped connecting bracket 31 is fixedly connected between the two driving members 32. Crushing and disintegrating parts 33 are provided at the left and right ends of the I-shaped connecting bracket 31 and directly above the blocking mechanism 5. A first driving motor 34 is fixedly installed on the front side of the upper surface of the I-shaped connecting bracket 31.

[0054] like Figure 3 As shown, the driving member 32 includes two axially symmetrical connecting supports 323 fixedly connected to the upper and lower surfaces of the loading bucket 2, and the two connecting supports 323 arranged above and below are connected with a threaded rod 322 that rotates together. The top ends of the four threaded rods 322 are each provided with a second pulley and the four second pulleys are jointly driven by a second belt. The rear side of the upper surface of the I-shaped connecting bracket 31 is fixedly connected to a third driving motor 321, and the bottom end of the output shaft of the third driving motor 321 is fixedly connected to the second pulley on the right rear side threaded rod 322.

[0055] like Figure 3As shown, taking the crushing and breaking piece 33 on the right side as an example, the crushing and breaking piece 33 includes a fixed bracket 332 fixedly connected to the right side of the I-shaped connecting bracket 31, and the lower surface of the fixed bracket 332 is fixedly connected to a cover plate 333, and the upper surface of the cover plate 333 is provided with a water adding hole, and the diameter of the cover plate 333 is the same as the inner diameter of the loading bucket 2. A plurality of connecting pins 331 are evenly arranged on the circumferential surface of the cover plate 333, and a card groove corresponding to the connecting pins 331 is opened on the inner circumferential surface of the loading bucket 2. Two symmetrical limit slides 336 are fixedly connected to the upper and lower surfaces of the loading bucket 2, and the two limit slides 336 are fixedly connected to the limit slide rod 335.

[0056] An auxiliary support plate is provided in the middle position of the right side of the fixed bracket 332, and the limiting slide bar 335 is slidably connected to the auxiliary support plate on the fixed bracket 332. The lower surface of the cover plate 333 is rotatably connected to the single-head crushing leaf shaft 334, and the bottom end of the circumferential surface of the single-head crushing leaf shaft 334 is also provided with a crushing blade. The top of the single-head crushing leaf shaft 334 passes through the upper surface of the fixed bracket 332 and is provided with a first pulley. The diameter of the pulley at the top of the single-head crushing leaf shaft 334 on the left is smaller than the pulley at the top of the single-head crushing leaf shaft 334 on the right. The output shaft of the first drive motor 34 is also provided with a first pulley and is driven by a first belt and the first pulleys at the top of the left and right single-head crushing leaf shafts 334.

[0057] During specific use, the third drive motor 321 is first used to drive the threaded rod 322 on the right rear side to rotate on its corresponding connecting support 323, and the threaded rod 322 on the right rear side is driven by the second belt, so that the remaining three threaded rods 322 rotate synchronously with the threaded rod 322 on the right rear side. When the threaded rod 322 drives the fixed bracket 332 to move upward on it during the rotation, the cover plate 333 moves synchronously with the fixed bracket 332. At the same time, when the fixed bracket 332 slides upward on the circumferential surface of the limiting slide bar 335, it can be ensured that the fixed bracket 332 maintains sliding in the vertical direction.

[0058] Then, coniferous forest fiber and Tencel fiber are added to the two loading buckets 2 respectively. At this time, the third drive motor 321 is reversed, driving the threaded rod 322 to reverse, so that the fixed bracket 332 drives the cover plate 333 to move downward until the connecting pin 331 is engaged with the inside of the slot on the loading bucket 2. At this time, the third drive motor 321 stops rotating, the cover plate 333 moves to the specified position, and then a certain amount of water is added to the interior of the loading bucket 2 through the water filling hole on the cover plate 333 to assist in crushing and mixing the coniferous forest fiber or Tencel fiber. At this time, the first drive motor 34 drives the single-head crushing blade shaft 334 through the pulleys at the top of the left and right single-head crushing blade shafts 334 to crush and disperse the coniferous forest fiber or Tencel fiber inside the loading bucket 2. Due to the different crushing difficulty of coniferous forest fiber and Tencel fiber, the different diameters of the two pulleys make the rotation speeds of the two single-head crushing blade shafts 334 different, thereby meeting the synchronous crushing of coniferous forest fibers and Tencel fibers with two different crushing difficulties.

[0059] like Figure 4 As shown, the second driving mechanism 7 includes a transmission member 71 arranged on the rear surface of the mixing box 1, and a second driving motor 72 is fixedly installed on the transmission member 71. The left and right sides of the rear surface of the mixing box 1 are rotatably connected to the transmission seat 73, and the transmission seat 73 and its corresponding double-headed crushing blade shaft 6 are driven by a belt.

[0060] like Figure 4 and Figure 5 As shown, the transmission member 71 includes a fixed box 711 fixedly connected to the rear surface of the mixing box 1, and the first gear 713 is rotatably connected to the left side of the inner wall of the bottom end of the fixed box 711, and the first gear 713 and the transmission seat 73 on the left are driven by a belt. The second gear 714 is rotatably connected to the right side of the inner wall of the bottom end of the fixed box 711, and the second gear 714 and the transmission seat 73 on the right are driven by a belt. The first gear 713 is meshed with the second gear 714, and the output shaft of the second drive motor 72 passes through the interior of the fixed box 711 and is fixedly connected to the first gear 713.

[0061] During specific use, when the single-head crushing leaf shaft 334 starts to crush, the first gear 713 is synchronously driven by the second drive motor 72 to rotate inside the fixed box 711. While the first gear 713 drives the second gear 714 to rotate, the double-head crushing leaf shaft 6 is driven to rotate synchronously on the loading bucket 2 through the transmission seat 73. At this time, the two double-head crushing leaf shafts 6 rotate in opposite directions, cooperating with the single-head crushing leaf shaft 334 to synchronously crush and disperse the coniferous forest fibers or Tencel fibers inside the loading bucket 2.

[0062] like Figure 6As shown, the blocking mechanism 5 includes two upper and lower symmetrical limit members 53 arranged on the outer circumference of the loading bucket 2, and a baffle 51 is slidably connected to the two limit members 53. A pushing member 52 is provided on the outer circumference of the loading bucket 2 and located between the two limit members 53.

[0063] like Figure 6 As shown, the processing mechanism 4 includes a conveying member 41 fixedly arranged on the upper surface of the mixing box 1, a plurality of arc-shaped connecting pieces 43 distributed up and down are fixedly connected to the outer circumference of the baffle 51, and a cleaning member 42 is commonly arranged on the inner circumference of the plurality of arc-shaped connecting pieces 43.

[0064] like Figure 7 、 Figure 8 、 Figure 9 and Figure 12 As shown, the cleaning piece 42 includes an arcuate fixed shell 421 fixedly connected to the arcuate connecting piece 43, and the arcuate fixed shell 421 is fixedly connected to the baffle 51. A plurality of elastic sliding connection connecting heads 425 are evenly distributed on the upper and lower inner walls of the arcuate fixed shell 421 close to the center of the loading bucket 2. The connecting head 425 is penetrated and slidably connected to the side away from the center of the loading bucket 2. The end of the positioning slide away from the connecting head 425 is fixedly connected to the arcuate fixed shell 421. An air outlet 424 is provided on the connecting head 425 along the radial direction of the loading bucket 2. The upper and lower ends of the outer circumference of the arcuate fixed shell 421 are provided with a compression inclined groove 422. The opposite surfaces of the two loading buckets 2 are provided with filter holes. Crushing blades are provided on the upper and lower circumferential surfaces of the double-headed crushing blade shaft 6 and on the inner and outer sides of the loading bucket 2. Rubber sealing gaskets are provided on the inner circumferential surfaces of the baffle 51 and the arcuate fixed shell 421.

[0065] like Figure 7 、 Figure 10 and Figure 12 As shown, taking the limiting member 53 on the upper side as an example, the limiting member 53 includes a plurality of connecting columns 533 fixedly connected to the upper surface of the loading bucket 2, and the bottom ends of the plurality of connecting columns 533 are commonly fixedly connected to the limiting track 531, and a clamping inclined block 532 is fixedly connected to the rear side of the upper surface of the limiting track 531. An auxiliary slide groove 534 is provided on the inner circumference of the limiting track 531, and a card block adapted to the auxiliary slide groove 534 is provided on the outer circumference of the baffle 51 and the arc-shaped fixed shell 421.

[0066] like Figure 7 、 Figure 10 and Figure 11As shown, the pushing member 52 includes a connecting groove 524 opened on the outer circumferential surface of the loading bucket 2, and the internal circumferential sliding connection of the connecting groove 524 is a transmission rack 522, and the upper and lower surfaces of the end of the transmission rack 522 close to the baffle 51 are hinged with a connecting plate 523, and the end of the connecting plate 523 away from the transmission rack 522 is fixedly connected to the baffle 51, and a transmission gear 521 is fixedly connected to the front threaded rod 322, and the transmission gear 521 is engaged with its corresponding transmission rack 522.

[0067] When in use, when the threaded rod 322 reverses and drives the cover plate 333 to move downward to cover the top of the loading bucket 2, the threaded rod 322 on the front side synchronously drives the transmission rack 522 to slide inside the connecting slide groove 524 through the transmission gear 521, and pushes the baffle 51 to cover the filter hole position on the loading bucket 2 again through the connecting plate 523. At the same time, the block on the baffle 51 slides inside the auxiliary slide groove 534, so that the baffle 51 can rotate smoothly along the outer circumference of the loading bucket 2. While the baffle 51 moves, it drives the arc-shaped fixed shell 421 to rotate synchronously. When the baffle 51 moves to the specified position, the pressing inclined groove 422 on the arc-shaped fixed shell 421 and the pressing inclined groove 422 on the arc-shaped fixed shell 421 are in contact with each other. The inclined surface block 532 is engaged, and the inclined surface on the pressing chute 422 and the inclined surface on the pressing inclined surface block 532 are in contact and engaged with each other, so that the pressing inclined surface block 532 generates pressure on the arc-shaped fixed shell 421 toward the center of the loading bucket 2. At this time, the baffle 51 is pressed against the loading bucket 2, and the rubber sealing gaskets on the baffle 51 and the arc-shaped fixed shell 421 are slightly deformed and tightly attached to the loading bucket 2, thereby sealing the filter hole position on the loading bucket 2. Since the transmission rack 522 is hinged to the baffle 51 through the connecting plate 523, when the baffle 51 is moved by the extrusion force, the transmission rack 522 will not generate resistance to the baffle 51, thereby ensuring that the baffle 51 can better seal the filter hole position on the loading bucket 2.

[0068] like Figure 13 As shown, the conveying member 41 includes a connecting support frame 411 fixedly connected to the upper surface of the mixing box 1, and the rear surfaces of the two inclined sections of the connecting support frame 411 are fixedly connected with connecting hoses 413, and the end of the connecting hose 413 away from the connecting support frame 411 is fixed and connected through the outer circumference of the arc-shaped fixed shell 421, and the front surface of the mixing box 1 is fixedly connected with a fixing block 414, and the fixed block 414 is fixedly connected with a conveying pipe 412, and the left and right ends of the horizontal section of the conveying pipe 412 are respectively fixed and connected through the two connecting hoses 413.

[0069] During specific use, when the baffle 51 is re-covering the filter holes on the loading barrel 2, pressurized air is delivered to the inside of the connecting hose 413 through the delivery pipe 412, and is sprayed onto the filter holes through the connecting head 425 to clean the filter holes and avoid clogging of the filter holes. When the baffle 51 slides to the specified position, the connecting head 425 is aligned with the last row of filter holes. When stirring and mixing is performed inside the loading barrel 2, pressurized air is continuously sprayed into the inside of the loading barrel 2 to form a radial shear force to assist in the crushing and breaking up work. At the same time, the qualified coniferous forest fiber or Tencel fiber entering the mixing box 1 is stirred and mixed by the double-headed crushing blade shaft 6 when the loading barrel 2 restarts the crushing and breaking up. Before the loading barrel 2 completes the next crushing and breaking up, the mixed pulp inside the mixing box 1 is extracted by an external extraction device and transported to the next process to complete the preparation of the pulp.

[0070] Working principle: During specific use, the physically treated coniferous forest fibers or Tencel fibers are first mixed with water and delivered to the interior of the two loading barrels 2, and then the cover plate 333 is covered on the top of the loading barrel 2, and the coniferous forest fibers or Tencel fibers inside the loading barrel 2 are synchronously crushed and broken up in the up and down directions by the single-head crushing blade shaft 334 and the double-head crushing blade shaft 6. After the crushing and breaking up is completed, the two threaded rods 322 on the loading barrel 2 are driven to rotate synchronously by the third drive motor 321, and the cover plate 333 is lifted upward to open the top of the loading barrel 2. At the same time, the threaded rod 322 drives the transmission rack 522 to slide through the transmission gear 521 during rotation, and pulls the baffle 51 away from the filter hole on the loading barrel 2 through the connecting plate 523. At this time, qualified coniferous forest fibers or Tencel fibers flow out from the inside of the loading barrel 2 to the inside of the mixing box 1.

[0071] When all qualified coniferous forest fibers or Tencel fibers have flowed out from the interior of the loading barrel 2, the unqualified ones continue to remain in the loading barrel 2, and then new coniferous forest fibers or Tencel fibers are re-added to the loading barrel 2. At this time, the threaded rod 322 is driven to reverse by the third drive motor 321, and the cover 333 is re-covered on the top of the loading barrel 2. At the same time, the threaded rod 322 drives the transmission rack 522 to slide through the transmission gear 521 to re-cover the baffle 51 at the filter hole position on the loading barrel 2. In the process of the baffle 51 re-covering the filter hole on the loading barrel 2, pressurized air is delivered to the interior of the connecting hose 413 through the delivery pipe 412, and is sprayed onto the filter hole through the connecting head 425, so as to clean the filter hole and avoid clogging of the filter hole.

[0072] When the baffle 51 slides to the specified position, the connector 425 is aligned with the last row of filter holes. When stirring and mixing are performed inside the loading barrel 2, pressurized air is continuously sprayed into the interior of the loading barrel 2 to form a radial shear force to assist in the crushing and breaking up work. At the same time, the qualified coniferous forest fiber or Tencel fiber entering the mixing box 1 is stirred and mixed by the double-headed crushing blade shaft 6 during the process of restarting the crushing and breaking up in the loading barrel 2. Before the loading barrel 2 completes the next crushing and breaking up, the mixed pulp inside the mixing box 1 is extracted by an external extraction device and transported to the next process, thereby completing the preparation of the pulp.
