Description

Technical Field

[0001] This utility model relates to the field of flash explosion device technology, specifically a flash explosion device for modifying biomass fibers. Background Technology

[0002] With increasing environmental awareness and the growing acceptance of sustainable development concepts, biomass fiber, as a renewable resource, has been widely used in numerous fields, such as textiles and composite materials. To further improve the performance of biomass fibers and meet the needs of different application scenarios, modification treatment is particularly important. Flash explosion technology is an effective method for modifying biomass fibers. It uses a sudden high-temperature, high-pressure environment to cause structural changes in biomass fibers, thereby improving their physical and chemical properties, such as enhancing fiber strength, flexibility, and hydrophilicity, thus expanding their application range.

[0003] Currently, existing biomass fiber flash explosion devices on the market have some shortcomings in practical applications. Traditional flash explosion devices mostly use continuous feeding, which easily leads to material accumulation and uneven distribution during the feeding process. When the material is unevenly distributed within the reaction chamber, some areas may receive insufficient flash explosion energy, while other areas may be damaged due to excessive flash explosion. Ultimately, this results in an unsatisfactory flash explosion treatment effect, with inconsistent biomass fiber modification quality, failing to achieve the desired performance improvement. Furthermore, traditional material conveying structures are relatively simple and cannot effectively ensure a flat distribution of material within the reaction chamber, further exacerbating the problem of uneven flash explosion.

[0004] Based on this, this solution proposes a flash explosion device for biomass fiber modification. Utility Model Content

[0005] The purpose of this invention is to provide a flash explosion device for modifying biomass fibers, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flash explosion device for biomass fiber modification, comprising a storage unit, an intermittent feeding unit, a pushing unit, a leveling unit, and a flash explosion unit. The storage unit is used to store biomass fiber materials. The intermittent feeding unit is connected to the storage unit to achieve intermittent material feeding. The pushing unit receives the material falling from the intermittent feeding unit and transports it to the leveling unit. The leveling unit is connected to the flash explosion unit to evenly spread the material into the flash explosion unit. Both the pushing unit and the flash explosion unit are installed on a support base. The bottom of the flash explosion unit is provided with a discharge pipe for discharging the processed material.

[0007] Preferably, the storage unit includes a storage bin and a feed pipe, the feed pipe connecting the inside of the storage bin to the inside of the pushing unit; the intermittent feeding unit includes a drive component and a baffle component, the drive component is an electric telescopic rod, the baffle component is a baffle plate, the electric telescopic rod is installed on the pushing unit, its output end is connected to the baffle plate passing through the pushing unit, the baffle plate is set below the feed pipe, and the electric telescopic rod drives the baffle plate to move back and forth to intermittently open or close the feeding channel of the feed pipe.

[0008] By adopting the above technical solution, the baffle plate can be precisely moved back and forth by the electric telescopic rod, realizing the intermittent opening and closing of the feeding pipe channel. This can not only prevent a large amount of material in the storage box from rushing into the pushing unit at one time, causing accumulation and blockage, but also ensure that the material enters the subsequent conveying stage in a uniform and quantitative manner, providing an early guarantee for the stable operation of the entire device and the uniformity of subsequent flash explosion treatment. At the same time, the structure is simple and easy to operate, and it is convenient to adjust the intermittent feeding frequency according to the actual material processing volume.

[0009] Preferably, the pushing unit includes a pushing tube, a drive motor, and a spiral conveying rod. The pushing tube is mounted on a support base via a fixing frame. The drive motor is mounted at one end of the pushing tube, and its output end is fixedly connected to the spiral conveying rod rotatably mounted inside the pushing tube. The end of the pushing tube away from the drive motor is provided with a receiving funnel for receiving materials and guiding them to the material leveling unit.

[0010] By adopting the above technical solution, the push tube can be firmly installed on the support base with the help of the fixed frame, ensuring structural stability during the push process; when the drive motor drives the spiral conveyor to rotate, the spiral structure can be used to smoothly and continuously convey the material forward, effectively preventing the material from stagnating or accumulating in the push tube, and the receiving funnel at the end of the push tube can accurately receive the conveyed material and smoothly guide it to the material leveling unit, realizing a seamless connection between intermittent feeding and material leveling, and improving the overall material conveying efficiency.

[0011] Preferably, the material leveling unit includes a connecting pipe, a feeding pipe, a fixing ring, and a driving mechanism. The fixing ring is fixedly installed on the top of the flash explosion unit. The top end of the connecting pipe is fixedly connected to the receiving funnel and internally communicates with it. The bottom end of the connecting pipe is fixedly connected to the feeding pipe. The connecting pipe is rotatably installed on the fixing ring. A linkage gear is provided on the outer wall of the connecting pipe. The driving mechanism cooperates with the linkage gear to drive the connecting pipe to drive the feeding pipe to reciprocate. The flash explosion unit is fixedly installed on the top of the support base by a mounting bracket.

[0012] Using the above technical solution, the fixing ring provides stable rotational support for the connecting pipe, ensuring stability when the connecting pipe drives the feeding pipe to rotate; the connecting pipe connects the receiving funnel and the feeding pipe, ensuring smooth material flow, while the cooperation of the drive mechanism and the linkage gear can drive the connecting pipe to drive the feeding pipe to rotate back and forth, so that the feeding pipe can evenly spread the material into the flash explosion unit, avoiding material accumulation. At the same time, the flash explosion unit is firmly installed on the bearing base by the mounting bracket, ensuring structural safety during the flash explosion process and creating favorable conditions for the material to receive flash explosion treatment evenly.

[0013] Preferably, the drive mechanism includes a fixed box, a rotary motor, a flywheel, a double-section connecting rod, a sliding block, a U-shaped block, a sliding sleeve, a sliding rod, and a linkage rack. The fixed box is fixedly installed on the outside of the fixed ring. The rotary motor is located on the top of the fixed box, and its output shaft is fixedly connected to the flywheel. The flywheel is hinged to the sliding block through the double-section connecting rod. The sliding block is slidably installed inside the U-shaped block. The U-shaped block is fixedly installed on the sliding sleeve. The sliding sleeve is slidably sleeved on the sliding rod. The sliding rod is fixedly installed inside the fixed box. The linkage rack is fixedly connected to the sliding sleeve and meshes with the linkage gear. A return spring is sleeved on the sliding rod, and the two ends of the return spring are fixed to the sliding rod and the sliding sleeve, respectively.

[0014] Using the above technical solution, the fixed box can protect and position the various components of the drive mechanism, ensuring the orderly operation of the components; after the rotating motor drives the flywheel to rotate, through the transmission of the double-section connecting rod, sliding block, and return block, the rotational motion of the flywheel can be converted into the reciprocating linear motion of the sliding sleeve along the sliding rod. The sliding sleeve drives the linkage rack to move synchronously, and then meshes with the linkage gear to drive the connecting pipe to rotate. The return spring can assist the sliding sleeve to quickly return to its original position, ensuring the smoothness and stability of the reciprocating motion, realizing precise control of the reciprocating rotation of the feeding pipe, and ensuring the uniform spreading of materials.

[0015] Preferably, it also includes a control panel, which is installed on the top of the support base and is electrically connected to the electric telescopic rod, the drive motor, and the rotation motor; buffer pads are fixedly installed at the four corners of the bottom of the base.

[0016] By adopting the above technical solution, the control panel can centrally control the electric telescopic rod, drive motor, and rotation motor. Operators can conveniently adjust the operating parameters of each component, such as intermittent feeding frequency, pushing speed, and uniform material rotation speed, through the control panel, which greatly improves the convenience and automation of the device operation. The buffer pads at the four corners of the base can effectively absorb the vibration generated during the operation of the device, reduce the impact of vibration on the connection stability of each component and the overall operating accuracy, and at the same time reduce the noise of the device during operation, improving the comfort of the working environment.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] First, it solves the problem of material accumulation and uneven distribution caused by continuous feeding in traditional devices. This utility model uses an intermittent feeding unit, in which an electric telescopic rod drives the baffle plate to move back and forth, realizing the intermittent opening and closing of the feeding pipe channel. This allows the material to fall into the pushing pipe evenly and quantitatively. Combined with the smooth pushing of the screw conveyor, it avoids material accumulation during the conveying process and ensures that the material enters the subsequent processing stage in an orderly manner, laying the foundation for uniform flash explosion.

[0019] Second, the uniform distribution of materials within the flash explosion unit is achieved through a material homogenization unit, improving the modification quality. The drive mechanism drives the linkage rack to reciprocate, meshing with the linkage gear to cause the connecting pipe and the feed pipe to rotate back and forth, uniformly distributing the material into the flash explosion machine. This ensures that each portion of material receives sufficient flash explosion energy, avoiding situations where some materials do not receive enough energy or are over-exploded, effectively improving the consistency and stability of biomass fiber modification, and ensuring that the modified fiber meets performance standards.

[0029] Combination Figure 1-4As shown, in this embodiment, the material leveling unit includes a connecting pipe 17, a feeding pipe 20, a fixing ring 19, and a driving mechanism. The fixing ring 19 is fixedly installed on the top of the flash explosion unit 6. The top end of the connecting pipe 17 is fixedly connected to the receiving funnel 5 and communicates internally with it. The bottom end of the connecting pipe 17 is fixedly connected to the feeding pipe 20. The connecting pipe 17 is rotatably installed on the fixing ring 19. A linkage gear 18 is provided on the outer wall of the connecting pipe 17. The driving mechanism cooperates with the linkage gear 18 to drive the connecting pipe 17 to drive the feeding pipe 20 to reciprocate. The flash explosion unit 6 is fixedly installed on the top of the bearing base 1 through the mounting bracket 9. The driving mechanism includes a fixing box 21, a rotating motor 22, a flywheel 26, a double-section connecting rod 27, and a sliding block 28. The components include a retaining block 29, a sliding sleeve 24, a sliding rod 25, and a linkage rack 23. A fixed box 21 is fixedly installed on the outside of a fixed ring 19. A rotating motor 22 is located on the top of the fixed box 21, and its output shaft is fixedly connected to a flywheel 26. The flywheel 26 is hinged to a sliding block 28 via a double-section connecting rod 27. The sliding block 28 is slidably installed inside the retaining block 29. The retaining block 29 is fixedly installed on the sliding sleeve 24. The sliding sleeve 24 is slidably sleeved on the sliding rod 25. The sliding rod 25 is fixedly installed inside the fixed box 21. The linkage rack 23 is fixedly connected to the sliding sleeve 24 and meshes with the linkage gear 18. A return spring 16 is sleeved on the sliding rod 25, and the two ends of the return spring 16 are fixed to the sliding rod 25 and the sliding sleeve 24, respectively.

[0030] In this embodiment, the material distribution unit consists of a connecting pipe 17, a feeding pipe 20, a fixing ring 19, and a driving mechanism. The fixing ring 19 is fixedly installed on the top of the flash explosion unit 6, and its purpose is to provide stable rotational support for the connecting pipe 17. By rotating the connecting pipe 17 onto itself, it ensures that the connecting pipe 17 will not deviate when driving the feeding pipe 20 to rotate. The top end of the connecting pipe 17 is fixedly connected to the receiving funnel 5 and is internally connected. Its purpose is to receive the material conveyed by the receiving funnel 5. The internally connected structure allows the material to flow smoothly into the feeding pipe 20. The bottom end of the connecting pipe 17 is fixedly connected to the feeding pipe 20, and its purpose is to transfer the material to the feeding pipe 20. In conjunction with its own rotation, it drives the feeding pipe 20 to move synchronously, thereby achieving uniform material distribution. The outer wall of the 7th section is equipped with a linkage gear 18, which is used to cooperate with the drive mechanism to transmit power. By meshing with the linkage rack 23, the linear motion of the linkage rack 23 is converted into its own rotational motion. The flash explosion unit 6 is fixedly mounted on the top of the bearing base 1 by the mounting bracket 9, which is used to ensure the structural stability of the flash explosion unit 6 during operation. The fixing effect of the mounting bracket 9 prevents the flash explosion unit 6 from shifting due to vibration generated during the flash explosion. The drive mechanism includes a fixed box 21, a rotating motor 22, a flywheel 26, a double-section connecting rod 27, a sliding block 28, a return block 29, a sliding sleeve 24, a sliding rod 25, and a linkage rack 23. The fixed box 21 is fixedly mounted on the outside of the fixed ring 19, which is used to protect and position the various components of the drive mechanism. All components are centrally installed inside to avoid external interference and ensure orderly operation. The rotating motor 22 is located on top of the fixed box 21 and provides driving power. It is fixedly connected to the flywheel 26 via its output shaft, and upon startup, it drives the flywheel 26 to rotate. The flywheel 26 is hinged to the sliding block 28 via a double-section connecting rod 27, transmitting its rotational motion to subsequent components. The rotational power pulls the double-section connecting rod 27, thereby driving the sliding block 28. The sliding block 28 is slidably installed inside the retaining block 29, converting the pulling force of the double-section connecting rod 27 into a pushing force on the retaining block 29. By sliding within the retaining block 29, it pushes the retaining block 29 to move in its own direction of motion. The retaining block 29 is fixedly installed on the sliding sleeve 24. The sliding sleeve 24 is used to transmit power to the sliding sleeve 24, and its own movement drives the sliding sleeve 24 to slide on the sliding rod 25. The sliding sleeve 24 is slidably sleeved on the sliding rod 25, and its purpose is to drive the linkage rack 23 to perform reciprocating linear motion. By sliding along the sliding rod 25, it changes its own position, thereby realizing the movement of the linkage rack 23. The sliding rod 25 is fixedly installed in the fixed box 21, and its purpose is to provide a sliding track for the sliding sleeve 24. By its fixed installation, it restricts the sliding direction of the sliding sleeve 24 and ensures accurate movement. The linkage rack 23 is fixedly connected to the sliding sleeve 24 and meshes with the linkage gear 18. Its purpose is to convert the linear motion of the sliding sleeve 24 into the rotational motion of the linkage gear 18. By moving back and forth with the sliding sleeve 24, it drives the meshing linkage gear 18 to rotate in both directions.A return spring 16 is sleeved on the slide rod 25, with its two ends fixed to the slide rod 25 and the sliding sleeve 24 respectively. Its purpose is to assist the sliding sleeve 24 in quickly returning to its original position. Through its own elastic deformation, it generates a reverse elastic force after the sliding sleeve 24 moves, pushing it back to its initial position and ensuring smooth reciprocating motion.

[0031] Combination Figure 1-4 As shown, in this embodiment, a control panel 7 is also included. The control panel 7 is installed on the top of the support base 1 and is electrically connected to the electric telescopic rod 14, the drive motor 12, and the rotation motor 22. Buffer pads 8 are fixedly installed at the four corners of the bottom of the base 1.

[0032] In this embodiment, the device is also equipped with a control panel 7, which is fixedly installed on the top of the support base 1. Its purpose is to centrally control the operation of each power component of the device. By establishing an electrical connection with the electric telescopic rod 14, the drive motor 12, and the rotating motor 22, the operator can set parameters on the control panel 7, such as the extension and retraction frequency of the electric telescopic rod 14, the speed of the drive motor 12, and the start and stop timing of the rotating motor 22. This allows for precise adjustment of the intermittent feeding speed, material pushing efficiency, and uniform rotation amplitude, eliminating the need to operate individual components separately and greatly improving the ease of operation and automation of the device. Buffer pads 8 are fixedly installed at the four corners of the bottom of the support base 1. The purpose of the buffer pads 8 is to reduce vibration and noise during device operation. The extension and retraction of the electric telescopic rod 14 and the operation of the drive motor 12 and the rotating motor 22 will generate vibrations. The buffer pads 8 absorb these vibrations through their own elastic deformation, preventing the vibrations from being transmitted to the ground and causing the entire device to shake. They also reduce the noise generated by the vibrations, providing a more stable and quiet working environment. Furthermore, they indirectly protect the connection stability of the base 1 with other components and extend the service life of the device.

[0033] The working principle of this utility model is as follows: The material is first stored in the storage box 3. The electric telescopic rod 14 is started through the control panel 7, which drives the baffle plate 13 to move back and forth, realizing the intermittent opening and closing of the feeding pipe 11 feeding channel, so that the material falls into the pushing pipe 4 evenly and quantitatively. At the same time, after the drive motor 12 is started, it drives the spiral conveying rod 15 in the pushing pipe 4 to rotate. The spiral conveying rod 15 pushes the falling material forward smoothly through the spiral structure, avoiding material accumulation, and finally accurately guides the material to the receiving funnel 5, completing the orderly material conveying process.

[0034] After the material enters the connecting pipe 17 and the discharge pipe 20 through the receiving funnel 5, the rotating motor 22 starts and drives the flywheel 26 to rotate. The flywheel 26 drives the sliding block 28 to slide back and forth in the return block 29 through the double-section connecting rod 27, which in turn pushes the sliding sleeve 24 to move back and forth along the sliding rod 25. The movement of the sliding sleeve 24 drives the linkage rack 23 to move back and forth synchronously. The linkage rack 23 meshes with the linkage gear 18 on the outside of the connecting pipe 17, causing the linkage gear 18 to drive the connecting pipe 17 and the discharge pipe 20 at the bottom to rotate back and forth. Since the connecting pipe 17 is rotatably installed on the fixing ring 19 at the top of the flash explosion machine 6, the discharge pipe 20 can evenly spread the internal material into the flash explosion machine 6 during the rotation process, which provides a guarantee for the subsequent material to receive uniform flash explosion energy and achieve efficient modification. The material after flash explosion is finally discharged through the discharge pipe 10.
