Description

Technical Field

[0001] This invention relates to the field of pulp processing technology, and in particular to a deep dewatering and drying machine for pulp processing. Background Technology

[0002] Paper products are an indispensable part of daily life, providing great convenience and comfort to people in various aspects. In the production of paper products, the raw materials need to be crushed and pulped to turn them into paper pulp. The paper pulp contains a lot of water during the production process. If this water is not removed, it will affect the quality and performance of the paper. Therefore, a paper pulp dewatering dryer is needed to dry the paper pulp, which can remove excess water from the paper pulp, improve the quality and performance of the paper pulp, and meet the needs of subsequent processing and use.

[0003] Traditional pulp drying methods involve evenly feeding the pulp onto a conveyor belt, which then sends it into a dryer that uses steam to provide continuous high temperatures. The high temperature evaporates the moisture in the pulp. In this method, the pulp is in a piled-up state during drying, resulting in uneven heating. When the pulp piles up, the poor air circulation inside reduces heat transfer efficiency, slowing down the evaporation rate and making the evaporation process uneven, thus affecting the drying effect. Summary of the Invention

[0004] The purpose of this invention is to provide a deep dewatering dryer for pulp processing, which can agitate and disperse the pulp inside the drying cylinder, avoid uneven heating of the pulp which would slow down the evaporation rate of water, and increase the heating area of ​​the pulp during drying, thereby effectively improving the drying effect and solving the problems mentioned in the background art.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 5This invention provides a technical solution: a deep dewatering and drying machine for pulp processing, comprising a base frame 1, a fixed cylinder 2 fixedly connected to the top of the base frame 1, a drying cylinder 3 fixedly connected inside the fixed cylinder 2, a material conveying pipe 4 fixedly connected to the left side of the drying cylinder 3, a heat equalization component 6 arranged above the base frame 1, the heat equalization component 6 including a rotating shaft 61 rotatably connected to the middle part of the fixed cylinder 2, both ends of the rotating shaft 61 penetrating the fixed cylinder 2, a dispersing plate 62 fixedly connected to the outer wall of the rotating shaft 61 at a position inside the drying cylinder 3, and multiple dispersing plates 62 are arranged, the side of the dispersing plate 62 away from the rotating shaft 61 is in contact with the inner wall of the drying cylinder 3, and a motor 63 is fixedly connected to the right side of the fixed cylinder 2, the motor 63 conveying... Gears 64 are fixedly connected to the outer wall of the discharge shaft and the right side of the outer wall of the rotating shaft 61. The two gears 64 mesh with each other. A discharge pipe 10 is fixedly inserted into the bottom right side of the drying cylinder 3. An inlet pipe 11 is fixedly inserted into the top of the conveying pipe 4. A heating groove 15 is opened inside the fixed cylinder 2. A spiral blade 65 is fixedly connected to the left side of the rotating shaft 61, which extends into the conveying pipe 4. The diameter of the drying cylinder 3 gradually increases from left to right. A filter hole 12 is opened on the surface of the drying cylinder 3. Multiple filter holes 12 are opened. A drain hole 13 is opened at the bottom of the fixed cylinder 2, located to the left of the discharge pipe 10. A fixing bead 14 is fixedly connected to the inner side of the fixed cylinder 2. The fixing bead 14 is attached to the outer wall of the drying cylinder 3 at a position away from the fixed cylinder 2.

[0032] By adopting the above technical solution, the base frame 1 is used to fix the fixed cylinder 2. When the device is in use, the pulp to be dried is added into the inside of the conveying pipe 4 through the inlet pipe 11. As the output shaft of the motor 63 rotates, the gear 64 fixedly connected to the motor 63 rotates. Under the action of the two gears 64 meshing with each other, the gear 64 located on the right outer wall of the rotating shaft 61 drives the rotating shaft 61 to rotate, thereby causing the spiral blade 65 to rotate. The side of the spiral blade 65 away from the rotating shaft 61 is in contact with the inner wall of the conveying pipe 4. When the spiral blade 65 rotates, it can convey the pulp raw material, allowing the pulp raw material to enter the inside of the drying cylinder 3. Since the diameter of the drying cylinder 3 gradually increases from left to right, the inner side of the drying cylinder 3 is in an inclined state. As the rotating shaft 61 rotates, the dispersing plate 62 rotates. The dispersing plate 62 can agitate the pulp inside the drying cylinder 3, thereby facilitating the gradual conveying of the pulp to the right until the pulp reaches the right side of the drying cylinder 3 and is discharged from the discharge pipe 10.

[0033] It should be noted that the heating tank 15 is equipped with heating components for heating, including but not limited to heating wires, to heat the inside of the heating tank 15. The inner wall of the fixed cylinder 2 is made of a material with strong thermal conductivity, which can transfer the heat of the heating tank 15 to the inside of the drying cylinder 3 to dry the pulp inside the drying cylinder 3. As the inside of the drying cylinder 3 is tilted and the dispersing plate 62 agitates, the pulp is gradually conveyed to the right, allowing for continuous addition of pulp raw materials and continuous drying.

[0034] Furthermore, during the drying process, the continuous rotation of the dispersing plate 62 allows it to agitate and disperse the pulp inside the drying cylinder 3, preventing uneven heating of the pulp and thus slowing down the evaporation rate of moisture. It also increases the heating area of ​​the pulp during drying, thereby effectively improving the drying effect.

[0035] Specifically, such as Figures 1 to 5 As shown, a dual-channel rotary joint 66 is installed on the right side of the rotating shaft 61. A top tube 67 is fixedly inserted into the top of the dual-channel rotary joint 66. The end of the top tube 67 away from the dual-channel rotary joint 66 is inserted into the right side of the heating tank 15. A bottom tube 68 is fixedly inserted between the bottom end of the left side of the heating tank 15 and the bottom end of the dual-channel rotary joint 66. The interiors of the dispersion plate 62 and the rotating shaft 61 are both hollow. A partition plate 69 is fixedly connected inside the rotating shaft 61. A circulation pump 610 is fixedly installed in the middle part of the top tube 67.

[0036] By adopting the above technical solution, the dual-channel rotary joint 66 is a mature existing technology. Its principle and installation method will not be elaborated in detail. The design of the partition 69 divides the hollow part inside the rotating shaft 61 into two chambers, and the left side of the partition 69 does not contact the inner wall of the rotating shaft 61, so that the left side areas of the two chambers are connected. The two channels of the dual-channel rotary joint 66 are connected to the two chambers respectively. The circulating pump 610 is made of high-temperature resistant material. When the circulating pump 610 is started, the gas heated inside the heating tank 15 enters the interior of the top pipe 67, and then enters one of the chambers. With the flow of gas, the high-temperature gas enters the other chamber from the left side of the partition 69, and then enters the bottom left side of the heating tank 15 through the bottom pipe 68. This design facilitates the entry of the heated gas into the interior of the rotating shaft 61 and the interior of the dispersion plate 62. The dispersion plate 62 is made of a material with strong heat exchange. When the dispersion plate 62 agitates the pulp, it facilitates heat exchange with the heated air inside the pulp dispersion plate 62, further improving the drying effect.

[0037] Specifically, such as Figures 2 to 6As shown, the leftmost dispersing plate 62 is L-shaped. An extrusion assembly 7 is arranged on the left side of the interior of the drying cylinder 3. The extrusion assembly 7 includes an extrusion rod 71 fixedly connected to the inner side of the leftmost dispersing plate 62. The extrusion assembly 7 also includes a collection cover 72 fixedly connected to the inner wall of the left side of the drying cylinder 3. An extrusion plate 73 is arranged on the inner bottom side of the collection cover 72. A moving rod 74 is fixedly connected to the right side of the extrusion plate 73. A limiting arc ring 75 is fixedly connected to the right side of the moving rod 74. The right side of the limiting arc ring 75 is inclined. A ball 76 is rotatably connected to the left side of the extrusion rod 71. A stabilizing frame 77 is fixedly connected to the top of the limiting arc ring 75. The top of the stabilizing frame 77 is movably connected to the rotating shaft 61. A first spring 78 is fixedly connected between the stabilizing frame 77 and the collection cover 72. A bending frame 713 is fixedly connected to the bottom left side of the collection cover 72.

[0038] By adopting the above technical solution, as the rotating shaft 61 rotates with the dispersing plate 62, when the extrusion rod 71 on the leftmost dispersing plate 62 rotates close to the limiting arc ring 75, the left part of the extrusion rod 71 approaches the inclined part of the limiting arc ring 75. As the dispersing plate 62 continues to rotate, the extrusion rod 71 continues to extrude the limiting arc ring 75, causing the limiting arc ring 75 to move to the left. This causes the moving rod 74 to move with the extrusion plate 73 along the left side. When the extrusion rod 71 moves away from the limiting arc ring 75 with the rotation of the dispersing plate 62, the limiting arc ring 75 returns to its original position with the moving rod 74 under the elastic force of the first spring 78.

[0039] As the spiral blades 65 rotate, the pulp is discharged from the right side of the conveying pipe 4 and falls into the inside of the collection hood 72, and lands above the bending frame 713. It should be noted that the bottom of the extrusion plate 73 is in contact with the bottom of the bending frame 713. When the moving rod 74 moves the extrusion plate 73 to the left, the water in the pulp above the bending frame 713 can be squeezed out, so that the excess water in the pulp can be quickly dehydrated, avoiding the excessive water content in the pulp during the drying process, which would affect the drying effect.

[0040] It should be noted that when the extrusion rod 71 approaches the limiting arc ring 75 again, the limiting arc ring 75 has returned to its previous position to ensure continuous extrusion and dehydration. The design of the stabilizer 77 helps to improve the stability of the limiting arc ring 75 structure, and the design of the ball 76 helps to reduce the friction between the extrusion rod 71 and the limiting arc ring 75.

[0041] Specifically, such as Figures 4 to 7As shown, the extrusion assembly 7 also includes a guide plate 79 fixedly connected to the left side of the inner wall of the drying cylinder 3. A baffle 710 is slidably connected inside the collection hood 72 at a position corresponding to the guide plate 79. A limiting rod 711 is fixedly connected to the bottom of the baffle 710. A second spring 712 is fixedly connected between the baffle 710 and the collection hood 72. The limiting rod 711 slides inside the collection hood 72. A moving block 714 is slidably connected to the left side of the inside of the drying cylinder 3 at a position corresponding to the extrusion plate 73. A third spring 715 is fixedly connected between the moving block 714 and the drying cylinder 3.

[0042] By adopting the above technical solution, when the moving rod 74 moves the pressing plate 73 to the left, the right side of the pressing plate 73 moves away from the limiting rod 711. Under the elastic force of the second spring 712, the limiting rod 711 moves the shield 710 to the left. At this time, the left side of the shield 710 is attached to the right side of the guide plate 79, which prevents the pulp from falling into the right side area of ​​the pressing plate 73 when the pressing plate 73 moves and presses. When the limiting arc ring 75 is not pressed and the pressing plate 73 is in the initial state, the shield 710 is hidden inside the collection cover 72, and the guide plate 79 is set at an angle, which makes it easy for the pulp to fall above the bending frame 713 and be collected in the left side area of ​​the pressing plate 73. This design can ensure that when the pulp enters the drying cylinder 3, it can be dewatered by the pressing plate 73 first, avoiding some pulp that cannot be dewatered and affecting the final drying effect.

[0043] It should be noted that the elastic force of the first spring 78 is greater than that of the second spring 712.

[0044] It should be noted that there is a gap between the left side of the bending frame 713 and the left inner wall of the drying cylinder 3. When the third spring 715 is normally extended, the bottom right side of the moving block 714 is above the bending frame 713. When the extrusion plate 73 moves to the left to extrude water, the moving block 714 gradually moves to the left as the extrusion proceeds. After the extrusion is completed, the moving block 714 returns to its original position under the elastic force of the third spring 715. The design of the filter hole 12 facilitates the discharge of water.

[0045] Specifically, such as Figures 2 to 7 As shown, a slowing component 8 is provided on the left side of the moving block 714. The slowing component 8 includes a small rod 81 fixedly connected to the left side of the moving block 714. A piston 82 is fixedly connected to the left side of the small rod 81. A sleeve 83 is provided outside the piston 82. The outer wall of the sleeve 83 is fixedly connected to the drying cylinder 3. An elastic bladder 84 is fixedly connected to the left side of the sleeve 83. An inclined elastic strip 85 is fixedly connected to the inner wall of the sleeve 83. The elastic strip 85 gradually tilts to the left, and multiple elastic strips 85 are provided. A first elastic membrane 86 is fixedly connected to the outer wall of the elastic strip 85.

[0046] By adopting the above technical solution, during the process of extrusion plate 73 moving to the left to extrude water, moving block 714 gradually moves to the left, causing small rod 81 to move to the left, causing piston 82 to move to the left. The sleeve 83 is filled with a relatively viscous medium. When piston 82 moves to the left, the medium flows to the left and can enter the right side region of the sleeve 83, which is located on the first elastic membrane 86. Since both elastic strip 85 and first elastic membrane 86 are elastic, when the medium flows to the left, it can open the opening of the first elastic membrane 86, making the diameter of the opening of the first elastic membrane 86 larger, which facilitates the flow of the medium to the left. Elastic bladder 84 is elastic. When the medium flows to the left, elastic bladder 84 expands, and the two sides of sleeve 83 are connected to ensure that the air pressure on both sides is consistent.

[0047] After the dewatering is completed, the moving block 714 and the pressing plate 73 move to the right under the elastic force of the first spring 78 and the third spring 715. At this time, the medium in the sleeve 83 flows to the right. Under the pressure of the medium flow, the diameter of the opening of the first elastic membrane 86 becomes smaller, which slows down the flow of the medium. As a result, the moving block 714 moves slower than the pressing plate 73, so that the moving block 714 and the pressing plate 73 separate in the interval area between the bending frame 713 and the drying cylinder 3, which facilitates the discharge of the squeezed pulp.

[0048] It should be noted that the leftmost dispersing plate 62 extends a section on the side facing the direction of rotation to ensure that the pulp that has fallen into the drying cylinder 3 can be scraped away from the bottom of the dewatering area before squeezing and dewatering, so as to prevent the squeezed water from falling into the previously dewatered pulp and thus avoid affecting the drying effect of the pulp.

[0049] The design of the fixing bead 14 facilitates the separation of the inner wall of the fixing cylinder 2 from the drying cylinder 3, and the squeezed water can easily flow through the inclined flow inside the fixing cylinder 2 and be discharged from the drain hole 13.

[0050] Specifically, such as Figure 7 As shown, the moving block 714 and the pressing plate 73 are both fixedly connected to the side of each other, and the middle part of the two second elastic membranes 9 is fixedly connected to the magnetic block 5.

[0051] By adopting the above technical solution, when the extrusion dewatering is performed, the two magnetic blocks 5 attract each other, and the moving block 714 and the extrusion plate 73 are both provided with concave holes near the magnetic blocks 5. When the moving block 714 and the extrusion plate 73 are separated in the gap between the bending frame 713 and the drying cylinder 3, the magnetic force of the magnetic blocks 5 is small, and the magnetic blocks 5 can also be separated. When the magnetic blocks 5 are separated, the two second elastic films 9 shake, which makes it easier to shake out the pulp stuck on the second elastic films 9, and avoids some pulp sticking to the area of ​​the extrusion plate 73 and not being able to be discharged.

[0052] It should be noted that the magnetic block 5 is made of a high-temperature resistant material, and the aforementioned elastic material is also a high-temperature resistant material.

[0053] Working principle: The pulp to be dried is added into the conveying pipe 4 through the inlet pipe 11. The output shaft of the motor 63 rotates, causing the gear 64 fixedly connected to the motor 63 to rotate. This causes the gear 64, located on the right outer wall of the rotating shaft 61, to rotate the rotating shaft 61, thereby causing the spiral blade 65 to rotate. The side of the spiral blade 65 away from the rotating shaft 61 is in contact with the inner wall of the conveying pipe 4. When the spiral blade 65 rotates, it can convey the pulp raw material, allowing the pulp raw material to enter the interior of the drying cylinder 3. Since the diameter of the drying cylinder 3 gradually increases from left to right, the inner side of the drying cylinder 3 is in an inclined state. The dispersing plate 62 rotates, which can agitate the pulp inside the drying cylinder 3, thereby facilitating the gradual movement of the pulp to the right. The pulp is conveyed until it reaches the right side of the drying cylinder 3 and is discharged from the discharge pipe 10. The heat from the heating tank 15 is transferred to the inside of the drying cylinder 3 to dry the pulp inside. The dispersing plate 62 rotates continuously, which agitates and disperses the pulp inside the drying cylinder 3, preventing uneven heating of the pulp and slowing down the evaporation rate of water. It also increases the heating area of ​​the pulp during drying, thereby effectively improving the drying effect. The heated gas enters the interior of the rotating shaft 61 and the interior of the dispersing plate 62. The dispersing plate 62 is made of a material with strong heat exchange. When the dispersing plate 62 agitates the pulp, it facilitates heat exchange with the heated air inside the pulp dispersing plate 62, further improving the drying effect.

[0054] As the spiral blade 65 rotates, the pulp is discharged from the right side of the conveying pipe 4 and falls into the inside of the collection hood 72, landing above the bending frame 713. It should be noted that the bottom of the extrusion plate 73 is in contact with the bottom of the bending frame 713. When the moving rod 74 moves the extrusion plate 73 to the left, the water in the pulp above the bending frame 713 can be squeezed out. At the same time, the left side of the shield 710 is in contact with the right side of the guide plate 79 to prevent the pulp from falling onto the right side of the extrusion plate 73 during its movement and extrusion. Furthermore, when the limiting arc ring 75 is not extruded and the extrusion plate 73 is not... In the initial state, the baffle 710 is hidden inside the collection hood 72, and the guide plate 79 is tilted so that the pulp falls above the bending frame 713 and is collected in the left area of ​​the extrusion plate 73. This design ensures that when the pulp enters the drying cylinder 3, it can be dewatered by the extrusion plate 73 first. When the moving block 714 in the gap area between the bending frame 713 and the drying cylinder 3 and the extrusion plate 73 are separated, the magnetic force of the magnetic block 5 is small, and the magnetic block 5 can also be separated. When the magnetic block 5 is separated, the two second elastic films 9 shake, which makes it easy to shake off the second elastic films 9.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
