Technical Field
[0001] This utility model relates to a plant fiber separation device, belonging to the technical field of plant fiber processing equipment. Background Technology
[0002] Fiber separation is an important production process in fiberboard manufacturing. Fiber separation refers to the process of separating plant fiber raw materials into fine fibers. The purpose of fiber separation is to increase the specific surface area of the fibers, create favorable conditions for enhancing the bonding force between fibers in the fiberboard, and at the same time facilitate the uniform distribution of waterproofing agents and additives. A plant fiber separation device is provided in the related technology. The plant fiber separation device includes: a box body, a filter cylinder with a top opening inside the box body, the bottom of the filter cylinder being connected to the bottom of the box body through a stabilizing device, a crushing device inside the filter cylinder, and a heating pipe surrounding the outer wall of the box body. The working principle of this plant fiber separation equipment is as follows: Wood chips and water are fed into the filter cylinder inside the chamber through the feed hopper. Heating elements heat the inside of the chamber, softening the wood chips. After softening, excess water is discharged from the outlet. If the wood chips have excessive moisture content, heating can continue through the heating elements. During the crushing process, the motor drives the first rotating shaft, which in turn drives the first gear. The first gear meshes with the second gear, which in turn drives the second rotating shaft. The two second rotating shafts rotate, causing the blades on them to crush the wood chips. After crushing, the entire crushing device, along with the filter cylinder, can be removed through the cover. The filter cylinder can then be removed to easily extract the fibers. After the fibers are removed, the filter cylinder and crushing device are returned to the chamber. This plant fiber separation equipment integrates raw material softening and separation in the plant fiber separation process, reducing the use of equipment and costs while improving production efficiency. However, it also has obvious drawbacks: for example, when the wood chips have excessive moisture content, they can be further heated by heating tubes, increasing energy consumption; moreover, during the crushing process, the first rotating shaft is driven by a motor, which in turn drives the blades, and the operation of the heating tubes and the motor are powered separately, increasing energy consumption; furthermore, after the cellulose raw material is crushed, the entire crushing device can be removed from the filter cartridge through the cover, and then the filter cartridge can be removed to facilitate the extraction of fibers. After the fibers are removed, the filter cartridge and crushing device are put back into the housing, which is cumbersome due to the need to disassemble and reassemble the filter cartridge. Utility Model Content To solve the above-mentioned technical problems, this utility model provides a plant fiber separation device, which solves the problems of high energy consumption and the need to disassemble and reassemble filter cartridges for material feeding in the plant fiber separation equipment mentioned in the background art.

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-5 This utility model provides a technical solution: A plant fiber separation device, the plant fiber separation device comprising: The crushing mechanism is driven by flowing hot water, which can crush the raw materials during the process of softening cellulose raw materials with hot water, thereby improving the cellulose softening efficiency. At the same time, it can also perform pressure filtration and dewatering on the softened raw materials with high moisture content in the later stage. The crushing mechanism includes a crushing component 18 and a driving component. The driving component includes a rotating shaft 17, a pressure plate 19, a turbine 20, and a cylinder 8. The top end of the rotating shaft 17 is connected to the output end of the cylinder 8. The turbine 20, the pressure plate 19, and the crushing component 18 are installed on the rotating shaft 17 from top to bottom. The pressure plate 19 is funnel-shaped. When the pulverizing mechanism is activated to pulverize raw materials softened in hot water, the flowing hot water generates turbulent force, driving the turbine 20 to rotate at high speed. As the turbine 20 rotates, it drives the rotating shaft 17 to rotate, which in turn drives the pressure plate 19 and the pulverizing component 18 to rotate simultaneously. The rotating pressure plate 19 generates centrifugal force to prevent raw materials from adhering to it. Meanwhile, the rotating pulverizing component 18 operates at high speed, thus pulverizing the cellulose raw materials softened in hot water. Later, by activating cylinder 8 (which is located on pad 7), the rotating shaft 17 is pushed to move up and down, thereby changing the vertical working height of the crushing component 18. At the same time, the softened raw material can be filtered by the descending pressure plate 19. Please see Figure 5 In one embodiment of the present invention, the crushing component 18 includes a mounting base 24 and a blade holder 25. A rotating shaft 17 is installed at the axial position of the mounting base 24, and blade holders 25 are symmetrically distributed on both sides of the mounting base 24. A crushing blade is hinged and movably installed at one end of the blade holder 25. In this embodiment of the present invention, when the rotating shaft 17 rotates and drives the mounting base 24 of the crushing assembly 18 to rotate, the rotating mounting base 24 generates centrifugal force, which will adjust the position of the crushing blade hinged and movable on one side of the blade holder 25, so that it forms a horizontal straight line with the mounting base 24. As the mounting base 24 rotates at high speed, the crushing blade will also rotate at high speed, which is used to crush the softened raw materials. When the mounting base 24 stops rotating, the crushing blade is restored to its initial state under the action of gravity, which is convenient for the pressure plate 19 to perform pressure filtration on the raw materials later. Please refer to Figure 14. In one embodiment of this utility model, the plant fiber separating device further includes: The separation tank 4, the base 1, and the drive box 6 are provided. The separation tank 4 is installed on the base 1. The filter cartridge 14 and the chassis 15 are installed inside the separation tank 4. The filter cartridge 14 is located on the chassis 15. The crushing component 18 and the pressure plate 19 of the crushing mechanism are movably installed inside the filter cartridge 14. The top of the separation tank 4 is connected to the drive box 6. The drive component is installed inside the drive box 6. Meanwhile, a hot water pipe 9 is connected to one side of the drive box 6, and one end of the hot water pipe 9 is connected to the outlet of the hot water pump 11. A hot water valve 10 is installed on the hot water pipe 9. In addition, a feed inlet 5 is provided on one side of the upper end of the separator 4, and a discharge pipe 2 is connected to one side of the lower end of the separator 4. One end of the discharge pipe 2 passes through the inner wall of the filter cylinder 14, and a discharge valve 3 is installed on the discharge pipe 2. A drain pipe 13 is connected to the other side of the lower end of the separator 4. A drain valve 12 is installed on the drain pipe 13, and one end of the drain pipe 13 is connected to the inside of the separator 4. In embodiments of this invention, when the plant fiber separation device is used for separating and processing cellulose raw materials, After the raw material is fed into the filter cartridge 14 through the feed inlet 5, the hot water pump 11 is started. The hot water pump 11 operates and guides the external hot water through the hot water pipe 9 to the drive box 6. After the hot water flows into the drive box 6, it generates turbulent force, which can drive the turbine 20 of the drive component to rotate. When the turbine 20 rotates, it drives the rotating shaft 17 to rotate, which in turn causes the pressure plate 19 and the crushing component 18 installed on the rotating shaft 17 to rotate simultaneously. The rotating pressure plate 19 generates centrifugal force, which is used to fully stir and mix the raw material and hot water, improving the softening efficiency of the raw material. The rotating crushing component 18 crushes the raw material inside the filter cartridge 14, which also improves the softening efficiency of the raw material by the hot water. Later, when the raw material softening is complete and dehydration is required, the drain pipe 13 is opened and the cylinder 8 is started. The cylinder 8 outputs kinetic energy to drive the rotating shaft 17 to move up and down, thereby causing the pressure plate 19 installed on the rotating shaft 17 to move up and down, which is used to perform pressure filtration on the raw material inside the filter cartridge 14. When the raw material inside the filter cartridge 14 descends to a certain volume, the discharge pipe 2 is opened and the cylinder 8 is activated. The cylinder 8 pushes the pressure plate 19 to descend, so that the descending pressure plate 19 performs a pressure filtration operation on the softened raw material inside the filter cartridge 14 (during the descent of the rotating shaft 17, the crushing component 18 is folded and stored, and at the same time, the descending rotating shaft 17 moves along the shaft hole 16 opened on the surface of the chassis 15 until it is finally inserted into the shaft hole 16). At this point, hot water can be introduced again, causing the pressure plate 19 and the crushing component 18 to rotate simultaneously. The rotating pressure plate 19 forms a protective barrier, and the introduced hot water is centrifugally sprayed through the filter cylinder 14 and discharged through the drain pipe 13. Meanwhile, the rotating crushing component 18 stirs the raw material accumulated inside the filter cylinder 14 and discharges it from the discharge pipe 2 (a negative pressure pipe can also be connected at the discharge pipe 2 to draw out and discharge the filtered raw material). Please refer to the discharge pipe 24 in the figure. In one embodiment of this utility model, a turbulent channel is formed inside the drive box 6, and a filter plate 23 is installed inside the turbulent channel. A positioning seat 22 is provided on the filter plate 23. A sleeve 21 is provided at the lower end of the turbine 20, and the sleeve 21 is fitted onto the positioning seat 22. The sleeve 21 and the positioning seat 22 work together to position and support the turbine 20. When hot water is delivered into the drive box 6 through the hot water pipe 9, turbulent force is generated to drive the turbine 20 to rotate, which in turn causes the rotating shaft 17 set at the shaft center of the turbine 20 to rotate, thereby driving the pressure plate 19 and the crushing component 18 installed on the rotating shaft 17 to rotate simultaneously. The workflow of this embodiment is as follows: After the raw material is fed into the filter cartridge 14 through the feed inlet 5, hot water is then introduced into the drive box 6. The hot water generates turbulent force, which drives the turbine 20 to rotate. When the turbine 20 rotates, it drives the rotating shaft 17 to rotate, which in turn causes the pressure plate 19 and the crushing component 18 mounted on the shaft 17 to rotate simultaneously. The rotating pressure plate 19 generates centrifugal force, which is used to fully stir and mix the raw material and hot water, improving the softening efficiency of the raw material. Meanwhile, the rotating crushing component 18 crushes the raw material inside the filter cartridge 14, which also improves the softening efficiency of the raw material by the hot water. Later, when the raw material softening is complete and dehydration is required, the drain pipe 13 is opened and the cylinder 8 is started. The cylinder 8 outputs kinetic energy to drive the rotating shaft 17 to move up and down, thereby causing the pressure plate 19 installed on the rotating shaft 17 to move up and down, which is used to perform pressure filtration on the raw material inside the filter cartridge 14. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
