Description

Technical Field

[0001] This utility model relates to the field of wood pulp production technology, and in particular to a high-efficiency drying device for wood pulp production. Background Technology

[0002] Wood pulp is a fibrous material made from wood fibers through mechanical or chemical methods. It is a core raw material for industries such as papermaking, textiles, and packaging. Based on different production processes, it is mainly divided into three categories: chemical wood pulp, mechanical wood pulp, and chemimechanical wood pulp.

[0003] In the wood pulp production process, drying is a crucial step that determines pulp quality and production efficiency. Currently, the industry commonly uses drum dryers to dry wood pulp. The principle is that the rotation of the drum drives the pulp movement, utilizing hot air to fully contact the pulp and achieve moisture evaporation. However, most existing drying devices utilize drum dryers, making it inconvenient to filter and screen the pulp after drying. During the production and drying process, wood pulp inevitably produces fiber bundles, clumps, or is mixed with sawdust and impurities. Traditional drum dryers only have a single drying function and lack built-in filtration and screening structures. The dried pulp must be transferred to screening equipment for secondary processing, which not only increases production steps and equipment costs but also easily leads to pulp spillage and loss due to multiple transfers, reducing production efficiency. Furthermore, prolonged exposure of the pulp to the external environment poses a risk of re-absorbing moisture and becoming contaminated, affecting the final product quality. Therefore, this invention proposes a high-efficiency drying device for wood pulp production to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a high-efficiency drying device for wood pulp production, which solves the problem in the prior art where it is inconvenient to filter and screen the wood pulp after drying, resulting in low efficiency during wood pulp production.

[0019] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a high-efficiency drying device for wood pulp production, including a base plate 1 and a limiting structure.

One end of the drive gear 7 meshes with one side of the transmission gear ring 5. A discharge port 8 is opened at one end of the drum dryer body 4. A screening frame 9 is installed below the discharge port 8. A power mechanism is arranged below the screening frame 9. A discharge mechanism is arranged at one end of the screening frame 9.

[0020] The power mechanism includes a side plate 10, a movable rod 11, a telescopic spring 12, a mounting cavity 13, a second servo motor 14, a drive wheel 15, a transmission frame 16, and a transmission rod 17. The side plate 10 is mounted above the base plate 1 and is located at the front and rear ends of the screening frame 9. The movable rod 11 is inserted through the interior of the side plate 10, with one end of the movable rod 11 connected to one end of the screening frame 9. A telescopic spring 12 is provided on the outer wall of the movable rod 11, and a telescopic spring 12 is provided between the screening frame 9 and the side plate 10. The mounting cavity 13 is mounted at the top of the base plate 1. The second servo motor 14 is mounted at the front end of the mounting cavity 13. The drive wheel 15 is mounted inside the mounting cavity 13, and the output end of the second servo motor 14 is connected to one end of the drive wheel 15. A transmission frame 16 is provided on the outer side of the drive wheel 15. The drive wheel 15 has a semi-gear design, and the drive wheel 15 and the transmission frame 16 mesh with each other. A transmission frame 17 is mounted at the top of the transmission frame 16. The transmission rod 17 extends to the outside of the mounting cavity 13 and is connected to one end of the screening frame 9. In use, the dried wood pulp is discharged through the discharge port 8. At this time, the second servo motor 14 is started to drive the drive wheel 15 to rotate. Since the drive wheel 15 is a half gear design, under the limit of the limit rod 18 and the limit sleeve 19, the drive wheel 15 drives the transmission frame 16 to move back and forth, which in turn drives the transmission rod 17 to move back and forth. Therefore, with the cooperation of the movable rod 11 and the telescopic spring 12, the transmission rod 17 drives the screening frame 9 to move back and forth to screen the wood pulp. The qualified wood pulp is discharged through the inclined feeding plate 20, which can drive the screening frame 9 to move back and forth. The screening frame 9 screens the dried wood pulp to remove lumps and fiber bundles, break up and separate the lumps, keep the fibers in a single state, ensure the dispersion of wood pulp fibers, and separate non-fiber impurities, thereby greatly improving the practicality of the device in use.

[0021] The limiting structure includes a limiting rod 18 and a limiting sleeve 19. The limiting rod 18 is installed inside the lower part of the mounting cavity 13.

The cross-section of the limiting rod 18 is smaller than the cross-section of the limiting sleeve 19. The limiting rod 18 and the limiting sleeve 19 form a sliding structure. In use, the mutual cooperation between the limiting rod 18 and the limiting sleeve 19 can limit the movement of the transmission frame 16, making the transmission frame 16 more stable when moving.

[0022] A feeding plate 20 is installed on one side of the top of the base plate 1. The feeding plate 20 is located below the screening frame 9. The feeding plate 20 is designed to be inclined, which makes the wood pulp feeding more efficient.

Positioning holes 24 are located on both sides of the baffle 21. Positioning pins 25 are located inside the positioning holes 24. The inner diameter of the positioning hole 24 is larger than the outer diameter of the positioning pin 25. The positioning hole 24 and the positioning pin 25 form a locking structure. When it is necessary to adjust the screening frame 9... During cleaning, the positioning pin 25 is pulled out from the inside of the positioning hole 24. At this time, with the cooperation of the fixing groove 22 and the movable rail 23, the baffle 21 can be removed from the front end of the screening frame 9, so that the screening frame 9 can be cleaned conveniently. After cleaning, the baffle 21 can be conveniently installed by using the cooperation of the fixing groove 22 and the movable rail 23.

The baffle 21 can be easily disassembled and installed, making it easier and faster to clean the garbage and impurities inside the screening frame 9, thereby greatly improving the convenience of the device in use.

[0024] Working Principle: The operator first feeds the wood pulp through the inlet. At this time, the main body 4 of the drum dryer is started to dry the wood pulp. Simultaneously, the first servo motor 6 drives the drive gear 7 to rotate. Since the drive gear 7 meshes with the transmission gear ring 5, and with the cooperation of the limit wheel 3, the transmission gear ring 5 drives the main body 4 of the drum dryer to rotate, drying the wood pulp. The dried wood pulp is discharged through the outlet 8. Then, the second servo motor 14 is started to drive the drive wheel 15 to rotate. Because the drive wheel 15 has a semi-gear design, under the limit of the limit rod 18 and the limit sleeve 19, the drive wheel 15 drives the transmission frame 16 to reciprocate, thereby... The drive rod 17 moves back and forth, so with the cooperation of the movable rod 11 and the telescopic spring 12, the drive rod 17 drives the screening frame 9 to move back and forth to screen the wood pulp. The qualified wood pulp is discharged through the inclined feeding plate 20. When the screening frame 9 needs to be cleaned, the positioning pin 25 is pulled out from the inside of the positioning hole 24. At this time, with the cooperation of the fixed groove 22 and the movable rail 23, the baffle 21 can be removed from the front end of the screening frame 9, so that the screening frame 9 can be cleaned conveniently. After cleaning, the baffle 21 is conveniently installed by using the cooperation of the fixed groove 22 and the movable rail 23. Finally, the positioning pin 25 is inserted into the inside of the positioning hole 24 to fix the baffle 21.
