Abstract
Description
Technical Field
[0001] This invention relates to the field of bio-oil preparation equipment technology, specifically a heating reactor for bio-oil preparation based on crop straw. Background Technology
[0002] Before processing, the crops need to be crushed, dried, and then fed into the reactor. In an environment where oxygen is isolated or restricted, the reactor is rapidly heated to the target temperature. The high molecular weight organic polymers in the straw undergo a series of complex reactions such as chain breaking, decomposition, and recombination at high temperatures. The gaseous products generated by the reaction are quickly removed from the reaction zone and condensed. The condensable part is the brownish-black, viscous primary bio-oil. The core function of the bio-oil heating reactor is to convert agricultural and forestry waste such as crop straw into renewable liquid fuels and chemical raw materials, mainly bio-oil, through rapid pyrolysis or liquefaction processes under set high temperature, high pressure, and specific atmosphere conditions.
[0003] During the heating of the reactor, some of the vaporized bio-oil rises with the heat and adheres to the inner wall of the reactor. The conventional solution is to install vertical scrapers inside the reactor to remove the adhering bio-oil. However, since the primary bio-oil is viscous, most of it will stick to the outer wall of the scraper after scraping and cannot effectively drip down. To address these issues, the following solution is proposed. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides a heating reactor for the bio-oil production based on crop straw, comprising a tank body, a driver fixedly connected to the top of the tank body, a motor fixedly connected to the top of the driver, an input pipe extending through the top of the tank body, a motor fixedly connected to the top of the input pipe, a threaded rod fixedly connected to the output end of the motor, and an output end extending through the bottom of the tank body, and further comprising:
[0005] The power mechanism is fixedly installed at the output end of motor one;
[0006] The moving mechanism is rotatably mounted on the outer wall of the power mechanism;
[0007] The cleaning mechanism is fixedly installed on the side wall of the mobile mechanism;
[0008] Before using the equipment, the staff needs to stuff the crushed and dried straw into the input pipe, and then turn on the power to motor 2 and motor 1. Motor 2 will drive the threaded rod to rotate, and the threaded rod will transport the straw fragments inside the input pipe downwards and temporarily accumulate on the inner wall of the tank.
[0009] Preferably, the power mechanism includes:
[0010] The drive component is fixedly installed at the output end of motor one;
[0011] The cleaning component is slidably disposed on the inner wall of the tank.
[0012] When the motor drives the drive component to rotate, the drive component will drive the cleaning component to move up and down along the inner wall of the tank.
[0013] Preferably, the moving mechanism includes:
[0014] A limiting component is fixedly installed on the inner wall of the cleaning component;
[0015] A rotating component is located at the bottom of the cleaning component.
[0016] When the drive component rotates, the obstruction of the limiting component will cause the cleaning component to move up and down along the inner wall of the tank. At the same time, the rotating drive component will drive the rotating component to rotate.
[0017] Preferably, the cleaning facility includes:
[0018] The scraping component is fixedly installed on the inner wall of the rotating component;
[0019] The transmission component is fixedly installed on the inner wall of the scraping component;
[0020] The rotating component drives the scraping component to slide along the outer wall of the driving component, removing residual impurities from the driving component while the transmission component rotates and generates its own rotation.
[0021] Preferably, the drive assembly includes a bidirectional threaded rod fixedly connected to the output end of a motor, with a stirring frame fixedly connected to the end of the bidirectional threaded rod away from the motor, and three grooves formed on the side wall of the bidirectional threaded rod.
[0022] When the motor drives the mixing frame to rotate via the bidirectional threaded rod, the mixing frame will stir the straw fragments inside the tank.
[0023] Preferably, the cleaning component includes a second chute formed on the inner wall of the tank, a sliding frame slidably connected to the inner wall of the second chute, and a scraping plate fixedly connected to the bottom of the sliding frame;
[0024] The inner wall of the central through hole of the sliding frame is slidably connected to the outer wall of the bidirectional threaded rod, and the sliding frame can only slide up and down along the inner wall of the tank and cannot rotate.
[0025] Preferably, the limiting component includes a mounting groove formed in the inner wall of the central through hole of the sliding frame, a fixing rod fixedly connected to the inner wall of the mounting groove, and an arc-shaped limiting rod rotatably connected to the outer wall of the fixing rod;
[0026] The outer wall of the arc-shaped limiting rod fits against the inner wall of the threaded groove of the bidirectional threaded rod. When the bidirectional threaded rod rotates, the arc-shaped limiting rod will slide along the inner wall of the threaded groove of the bidirectional threaded rod, and at the same time drive the sliding frame to slide up and down.
[0027] Preferably, the rotating assembly includes a sliding ring rotatably connected to the bottom of the sliding frame, a sliding rod fixedly connected to the inner wall of the sliding ring, and a fixing frame fixedly connected to the side wall of the sliding ring.
[0028] The outer wall of the sliding rod is slidably connected to the inner wall of the first groove. When the bidirectional threaded rod rotates, the bidirectional threaded rod drives the sliding ring to rotate in the same direction through the sliding rod.
[0029] Preferably, the scraping component includes a fixed frame 1 fixedly connected to the inner wall of the fixed frame, a beveled scraper fixedly connected to the end of the fixed frame 1 away from the sliding ring, a hollow groove opened in the inner wall of the fixed frame 1, and a narrow scraper fixedly connected to the outer wall of the fixed frame 1.
[0030] In normal conditions, the sidewall of the inclined scraper is in contact with the inner wall of the scraper plate.
[0031] The present invention has the following beneficial effects:
[0032] (1) This invention addresses the problem that primary bio-oil adheres to the outer wall of the scraper and cannot effectively drip downwards. A rotating assembly is installed inside the device. When the bidirectional threaded rod rotates, because the sliding rod and the first sliding groove are in contact, the rotation of the bidirectional threaded rod will cause the sliding ring to rotate in the same direction. At this time, the fixing frame drives the first fixing frame and the inclined scraper to rotate around the sliding ring. Simultaneously, the inclined scraper will slide and scrape along the inner wall of the scraper, presenting a scraping effect as shown in the image. Figure 5 In the state of G, through the application of the above components, when the scraper slides down and scrapes the inner wall of the tank, the inclined scraper can promptly remove the primary bio-oil accumulated at the scraper position.
[0033] (2) This invention utilizes the characteristic of the aforementioned rotating component driving the inclined scraper to slide along the inner wall of the scraper plate. A transmission component is installed inside the device. Since the angle between the inclined surface of the conical contact column and the inclined surface of the outer wall of the inclined scraper is equal, when the inclined scraper slides along the inner wall of the scraper plate, the conical contact column will roll along the inner wall of the scraper plate. The rolling conical contact column will drive the rotating column one to mesh and rotate through gear one and gear two. At this time, the rotating column one and the conical contact column will drive the belt to slide along the outer wall of the rotating column two. Through the application of the aforementioned component, such as... Figure 10As shown, when the inclined scraper slides downwards, the primary bio-oil will accumulate at position K. The conical contact column and gear one will rotate clockwise, while simultaneously driving rotating column one and gear two to rotate counterclockwise, and driving the belt to rotate counterclockwise. The belt, which is close to K, will move along path L. This causes the primary bio-oil accumulated at position K to move towards the center of the tank under the drive of the belt, preventing the bio-oil from getting too close to the inner wall of the tank and sticking to the inner wall of the tank again when falling.
[0034] (3) The present invention utilizes the feature of the sliding frame sliding up and down along the inner wall of the tank. As the sliding frame moves down, the rotating component and the scraping component will rotate, and the rotating component and the scraping component will break up the straw fragments inside the tank. As the sliding frame moves down, the loose straw fragments will be submerged in the inner wall of the straw fragments. When it is lifted up later, some of the loose fragments will be affected by the upward movement of the sliding frame, and the fragments will be hollow. This allows the hot air inside the tank to quickly penetrate into the straw fragments, effectively accelerating the heating efficiency.
[0035] (4) In this invention, when the sliding frame moves from bottom to top, some debris will accumulate in the... Figure 6 At position G, as the sliding frame moves upward, the debris at position G will be evenly coated on the inner wall of the tank, forming a "film" on the inner wall. Subsequent bio-oil will adhere to the aforementioned "film" position. When the sliding frame slides down a second time, the scraper removes the "film" and the primary bio-oil above it, effectively reducing the total amount of primary bio-oil adhering to the inner wall of the tank and preventing excessive bio-oil from adhering to the inner wall of the tank, which would cause clumping.

[0051] 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.
[0052] Example 1, please refer to Figure 1 - Figure 9 This invention relates to a heating reactor for the bio-oil production process based on crop straw, comprising a tank body 13, a driver 14 fixedly connected to the top of the tank body 13, a motor 15 fixedly connected to the top of the driver 14, an input pipe 16 extending through the top of the tank body 13, a motor 17 fixedly connected to the top of the input pipe 16, a threaded rod 18 fixedly connected to the output end of the motor 17, and an output end 19 extending through the bottom of the tank body 13. The reactor also includes:
[0053] Power mechanism 1 is fixedly installed at the output end of motor 15;
[0054] The moving mechanism 2 is rotatably mounted on the outer wall of the power mechanism 1;
[0055] Cleaning mechanism 3 is fixedly installed on the side wall of the moving mechanism 2;
[0056] Before using the equipment, the staff needs to stuff the crushed and dried straw into the input pipe 16, and then turn on the power to the motor 17 and the motor 15. The motor 17 will drive the threaded rod 18 to rotate, and the threaded rod 18 will transfer the straw fragments inside the input pipe 16 downwards and temporarily accumulate on the inner wall of the tank 13.
[0057] Power mechanism 1 includes:
[0058] Drive component 11 is fixedly installed at the output end of motor 15;
[0059] Cleaning component 12 is slidably disposed on the inner wall of tank 13;
[0060] When the motor 15 drives the drive assembly 11 to rotate, the drive assembly 11 will drive the cleaning assembly 12 to move up and down along the inner wall of the tank 13.
[0061] Mobile mechanism 2 includes:
[0062] Restriction component 21 is fixedly disposed on the inner wall of cleaning component 12;
[0063] Rotating component 22 is rotatably disposed at the bottom of cleaning component 12;
[0064] When the drive component 11 rotates, the obstruction of the limiting component 21 will cause the cleaning component 12 to move up and down along the inner wall of the tank 13. At the same time, the rotating drive component 11 will drive the rotating component 22 to rotate.
[0065] Cleaning facility 3 includes:
[0066] The scraping component 31 is fixedly installed on the inner wall of the rotating component 22;
[0067] The transmission component 32 is fixedly disposed on the inner wall of the scraping component 31;
[0068] The rotating component 22 drives the scraping component 31 to slide along the outer wall of the driving component 11. While removing residual impurities from the driving component 11, the transmission component 32 rotates and generates its own rotation.
[0069] Example 2, please refer to Figure 4 - Figure 12 The present invention is a heating reactor for bio-oil preparation based on crop straw. Based on Example 1, the drive assembly 11 includes a bidirectional threaded rod 111 fixedly connected to the output end of motor 15. A stirring rack 112 is fixedly connected to the end of the bidirectional threaded rod 111 away from motor 15. Three sliding grooves 113 are opened on the side wall of the bidirectional threaded rod 111.
[0070] When the motor 15 drives the stirring frame 112 to rotate through the bidirectional threaded rod 111, the stirring frame 112 will stir the straw fragments inside the tank 13.
[0071] The cleaning component 12 includes a second groove 121 formed on the inner wall of the tank 13, a sliding frame 122 slidably connected to the inner wall of the second groove 121, and a scraping plate 123 fixedly connected to the bottom of the sliding frame 122.
[0072] When the equipment needs to scrape off the primary bio-oil on the inner wall of tank 13, the power supply of motor 15 is turned on. Since the outer wall of the arc-shaped limiting rod 213 is in contact with the inner wall of the thread groove of the bidirectional threaded rod 111, when the bidirectional threaded rod 111 rotates, the arc-shaped limiting rod 213 will slide along the inner wall of the thread groove of the bidirectional threaded rod 111, and at the same time drive the sliding frame 122 to slide up and down. When the sliding frame 122 slides down along the inner wall of tank 13, the scraping plate 123 will scrape the primary bio-oil on the inner wall of tank 13, completing the basic cleaning process.
[0073] The limiting component 21 includes a mounting groove 211 opened in the inner wall of the central through hole of the sliding frame 122, a fixing rod 212 fixedly connected to the inner wall of the mounting groove 211, and an arc-shaped limiting rod 213 rotatably connected to the outer wall of the fixing rod 212.
[0074] Utilizing the characteristic of the sliding frame 122 sliding up and down along the inner wall of the tank 13, as the sliding frame 122 moves downward, the rotating component 22 and the scraping component 31 will rotate, and the rotating component 22 and the scraping component 31 will break up the straw fragments inside the tank 13. As the sliding frame 122 moves downward, the loose straw fragments will be submerged in the inner wall of the straw fragments. When it is subsequently lifted upward, some of the loose fragments will be hollowed out due to the upward movement of the sliding frame 122, which allows the hot air inside the tank 13 to quickly penetrate into the straw fragments, effectively accelerating the heating efficiency.
[0075] The rotating assembly 22 includes a sliding ring 221 rotatably connected to the bottom of the sliding frame 122, a sliding rod 222 fixedly connected to the inner wall of the sliding ring 221, and a fixing frame 223 fixedly connected to the side wall of the sliding ring 221.
[0076] As the sliding frame 122 moves from bottom to top, some debris will accumulate. Figure 6 At position G, as the sliding frame 122 moves upward, the debris at position G will be evenly coated on the inner wall of the tank 13, forming a "film" on the inner wall of the tank 13. Subsequent bio-oil will adhere to the aforementioned "film" position. When the sliding frame 122 slides down for the second time, the scraping plate 123 removes the "film" and the primary bio-oil above it, effectively reducing the total amount of primary bio-oil adhering to the inner wall of the tank 13 and preventing excessive bio-oil from adhering to the inner wall of the tank 13, thus preventing the phenomenon of clumping on the inner wall of the tank 13.
[0077] The scraping component 31 includes a first fixed frame 311 fixedly connected to the inner wall of the fixed frame 223. A beveled scraper 312 is fixedly connected to the end of the first fixed frame 311 away from the sliding ring 221. A hollow groove 313 is opened in the inner wall of the first fixed frame 311. A narrow scraper 314 is fixedly connected to the outer wall of the first fixed frame 311.
[0078] To address the issue of primary bio-oil adhering to the outer wall of the scraping plate 123 and failing to drip effectively downwards, a rotating assembly 22 is installed inside the device. When the bidirectional threaded rod 111 rotates, the sliding rod 222 is in contact with the sliding groove 113. Therefore, the rotation of the bidirectional threaded rod 111 causes the sliding ring 221 to rotate in the same direction. At this time, the fixing frame 223 drives the fixing frame 311 and the inclined scraper 312 to rotate around the sliding ring 221. Simultaneously, the inclined scraper 312 slides and scrapes along the inner wall of the scraping plate 123, resulting in a scraping effect. Figure 5 In the state of G, through the application of the above components, when the scraper plate 123 slides down and scrapes the inner wall of the tank 13, the inclined scraper 312 can promptly remove the primary bio-oil accumulated at the position of the scraper plate 123.
[0079] The transmission assembly 32 includes a gear 321 rotatably connected to the inner wall of the hollow groove 313, a conical contact post 322 fixedly connected to the top of the gear 321, a gear 323 rotatably connected to the inner wall of the hollow groove 313, a rotating post 324 fixedly connected to the top of the gear 323, four rotating posts 325 rotatably connected to the inner wall of the hollow groove 313, and a belt 326 sleeved on the outer wall of the four rotating posts 325.
[0080] Utilizing the characteristic of the aforementioned rotating component 22 driving the inclined scraper 312 to slide along the inner wall of the scraper plate 123, a transmission component 32 is provided inside the equipment. Since the angle between the inclined surface of the conical contact post 322 and the inclined surface of the outer wall of the inclined scraper 312 is equal, when the inclined scraper 312 slides along the inner wall of the scraper plate 123, the conical contact post 322 will roll along the inner wall of the scraper plate 123. The rolling and rotating conical contact post 322 will drive the rotating post 324 to mesh and rotate through gear one 321 and gear two 323. At this time, the rotating post 324 and the conical contact post 322 will drive the belt 326 to slide along the outer wall of the rotating post two 325. Through the application of the above components, such as... Figure 10 As shown, when the inclined scraper 312 slides downward, the primary bio-oil will accumulate at position K. The conical contact column 322 and gear 1 321 will rotate clockwise, while simultaneously driving the rotating column 1 324 and gear 2 323 to rotate counterclockwise, and driving the belt 326 to rotate counterclockwise. The belt 326, which is close to the K side, will move along the path L. This causes the primary bio-oil accumulated at position K to move towards the center of the tank 13 under the drive of the belt 326, preventing the bio-oil from getting too close to the inner wall of the tank 13 and sticking to the inner wall of the tank 13 again when falling.
[0081] One specific application of this embodiment is as follows: Before using the equipment, the staff needs to stuff the crushed and dried straw into the input pipe 16, and then turn on the power of motor 2 17 and motor 1 15. Motor 2 17 will drive the threaded rod 18 to rotate, and the threaded rod 18 will transport the straw fragments inside the input pipe 16 downwards and temporarily accumulate on the inner wall of the tank 13.
[0082] When the equipment needs to scrape off the primary bio-oil on the inner wall of the tank 13, the power supply of motor 15 is turned on. Since the outer wall of the arc-shaped limiting rod 213 is in contact with the inner wall of the thread groove of the bidirectional threaded rod 111, when the bidirectional threaded rod 111 rotates, the arc-shaped limiting rod 213 will slide along the inner wall of the thread groove of the bidirectional threaded rod 111, and at the same time drive the sliding frame 122 to slide up and down. When the sliding frame 122 slides down along the inner wall of the tank 13, the scraping plate 123 will scrape the primary bio-oil on the inner wall of the tank 13, completing the basic cleaning process.
[0083] To address the issue of primary bio-oil adhering to the outer wall of the scraping plate 123 and failing to drip effectively downwards, a rotating assembly 22 is installed inside the device. When the bidirectional threaded rod 111 rotates, the sliding rod 222 is in contact with the sliding groove 113. Therefore, the rotation of the bidirectional threaded rod 111 causes the sliding ring 221 to rotate in the same direction. At this time, the fixing frame 223 drives the fixing frame 311 and the inclined scraper 312 to rotate around the sliding ring 221. Simultaneously, the inclined scraper 312 slides and scrapes along the inner wall of the scraping plate 123, resulting in a scraping effect. Figure 5 In the state of G, through the application of the above components, when the scraper plate 123 slides down and scrapes the inner wall of the tank 13, the inclined scraper 312 can promptly remove the primary bio-oil accumulated at the position of the scraper plate 123.
[0084] Utilizing the characteristic of the aforementioned rotating component 22 driving the inclined scraper 312 to slide along the inner wall of the scraper plate 123, a transmission component 32 is provided inside the equipment. Since the angle between the inclined surface of the conical contact post 322 and the inclined surface of the outer wall of the inclined scraper 312 is equal, when the inclined scraper 312 slides along the inner wall of the scraper plate 123, the conical contact post 322 will roll along the inner wall of the scraper plate 123. The rolling and rotating conical contact post 322 will drive the rotating post 324 to mesh and rotate through gear one 321 and gear two 323. At this time, the rotating post 324 and the conical contact post 322 will drive the belt 326 to slide along the outer wall of the rotating post two 325. Through the application of the above components, such as... Figure 10 As shown, when the inclined scraper 312 slides downward, the primary bio-oil will accumulate at position K. The conical contact column 322 and gear 1 321 will rotate clockwise, while simultaneously driving the rotating column 1 324 and gear 2 323 to rotate counterclockwise, and driving the belt 326 to rotate counterclockwise. The belt 326, which is close to the K side, will move along the path L. This causes the primary bio-oil accumulated at position K to move towards the center of the tank 13 under the drive of the belt 326, preventing the bio-oil from getting too close to the inner wall of the tank 13 and sticking to the inner wall of the tank 13 again when falling.
[0085] Utilizing the centrifugal force generated by the rotation of the aforementioned rotating component 22 and the fixed frame 311, a narrow scraper 314 is installed inside the equipment. When the belt 326 drives the primary bio-oil to contact the outer wall of the narrow scraper 314, the narrow scraper 314 will scrape off the bio-oil on the outer surface of the belt 326. Due to the inclination angle of the narrow scraper 314, the viscous bio-oil will move outward along the outer wall of the narrow scraper 314 in a path P. At this time, the bio-oil in the suspended state only has the contact point of the narrow scraper 314. With a small contact area, it will fall off due to the centrifugal force and eventually fall to the center of the tank 13.
[0086] Utilizing the characteristic of the sliding frame 122 sliding up and down along the inner wall of the tank 13, as the sliding frame 122 moves downward, the rotating component 22 and the scraping component 31 will rotate, and the rotating component 22 and the scraping component 31 will break up the straw fragments inside the tank 13. As the sliding frame 122 moves downward, the loose straw fragments will be submerged in the inner wall of the straw fragments. When it is lifted upward in the subsequent process, some of the loose fragments will be hollowed out due to the upward movement of the sliding frame 122. This allows the hot air inside the tank 13 to quickly penetrate into the straw fragments, effectively accelerating the heating efficiency.
[0087] Additionally, as the sliding frame 122 moves from bottom to top, some debris will accumulate. Figure 6 At position G, as the sliding frame 122 moves upward, the debris at position G will be evenly coated on the inner wall of the tank 13, forming a "film" on the inner wall of the tank 13. Subsequent bio-oil will adhere to the aforementioned "film" position. When the sliding frame 122 slides down for the second time, the scraping plate 123 removes the "film" and the primary bio-oil above it, effectively reducing the total amount of primary bio-oil adhering to the inner wall of the tank 13 and preventing excessive bio-oil from adhering to the inner wall of the tank 13, thus preventing the phenomenon of clumping on the inner wall of the tank 13.
