Description

Technical Field

[0001] This utility model relates to the technical field of preparing anti-flocculation chitosan oligosaccharides, and in particular to an anti-flocculation chitosan oligosaccharide preparation device. Background Technology

[0002] Antiflocculating chitosan oligosaccharide is a chitosan oligosaccharide derivative with specific functions, playing an important role in agriculture, environmental protection, and medicine mainly due to its antiflocculation properties. It is generally prepared by enzymatic hydrolysis using specific enzymes in a reactor. Chinese utility model patent CN213590445U discloses a reactor for chitosan oligosaccharide processing. This reactor includes a cylinder, an upper sealing cover, a lower sealing cover, and stirring blades. An operation panel is provided on one side wall of the cylinder, and a power interface is located below the operation panel. A first connection seat is provided on the other side wall of the cylinder, and a second connection seat is provided correspondingly on the cylinder. The advantages are: the design of the cylinder, insulation layer, and electric heating plate reduces heat loss during the heating process, thus avoiding the need for continuous energy consumption for heating and reducing processing costs. The design of injection pipe one, injection pipe two, and a solenoid valve allows the reactor to have two injection ports, enabling the simultaneous addition of different materials, demonstrating the practicality of the device.

[0003] However, the aforementioned reaction vessel does not have a structure for holding specific enzymes. Directly adding specific enzymes into the reaction vessel can easily cause them to be discharged along with the reaction solution. Furthermore, impurities in the raw materials can directly contact the specific enzymes, resulting in reduced activity and hindering the improvement of preparation efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an anti-flocculation chitosan oligosaccharide preparation device that uses a filter cylinder to constrain specific enzyme particles, reduces specific enzyme particle contamination, and improves the preparation efficiency of anti-flocculation chitosan oligosaccharide.

[0005] This invention relates to an anti-flocculation chitosan oligosaccharide preparation device, comprising a reaction tank and an inlet pipe. The reaction tank has an internal reaction chamber, and the inlet pipe extends into the reaction chamber. It also includes a filter cylinder, a central tube, multiple stirrers, an inlet, and an outlet. The filter cylinder is installed in the reaction chamber of the reaction tank, and its side wall has micropores. Specific enzyme particles are filled inside the filter cylinder. The central tube is rotatably vertically penetrating the reaction tank and the filter cylinder, and is rotatably connected to the top and bottom walls of the reaction tank. Wear-resistant sealing rings are provided between the central tube and the top and bottom walls of the reaction tank. Multiple stirrers are installed on the outer wall of the central tube, located inside the filter cylinder. An inlet is located on the upper side wall of the central tube, inside the filter cylinder, and at the outlet of the filter cylinder. An outlet is located at the lower end of the middle tube on the upper side of the micropores of the filter, below the reaction vessel. During operation, the raw material is fed into the reaction chamber between the inside of the reaction vessel and the outer wall of the filter tube through the inlet pipe. After being filtered through the micropores of the filter tube, the raw material comes into contact with the specific enzyme particles, thereby enzymatically hydrolyzing and preparing anti-flocculating chitosan oligosaccharide. The solution containing anti-flocculating chitosan oligosaccharide enters the middle tube through the inlet and is discharged from the reaction vessel through the outlet. During this process, the middle tube rotates, driving multiple stirrers to rotate. The stirrers agitate the specific enzyme particles and the raw material, making the contact more thorough and improving the reaction efficiency. Impurities in the raw material are filtered and intercepted by the micropores of the filter tube, preventing impurities from contaminating the specific enzyme particles, maintaining the activity of the specific enzyme particles, and improving the preparation efficiency of anti-flocculating chitosan oligosaccharide.

[0006] Preferably, it also includes a motor, a drive wheel, a driven wheel, and a transmission belt. The motor is mounted on the reaction vessel, the output shaft of the motor is concentrically mounted on the drive wheel, the driven wheel is concentrically mounted on the central tube, and the transmission belt is fitted onto the drive wheel and the driven wheel. The motor drives the drive wheel to rotate, the drive wheel drives the driven wheel to rotate through the transmission belt, and the driven wheel drives the central tube to rotate, thereby driving the central tube and multiple agitators.

[0007] Preferably, the system also includes an installation plate, multiple scrapers, and a discharge pipe. The installation plate is installed on the outer wall of the central tube and is located inside the reaction chamber of the reaction vessel, below the filter cartridge. Multiple scrapers are installed on the installation plate and scrape the outer wall of the filter cartridge. The discharge pipe is installed on the reaction vessel, with its input end extending into the bottom of the reaction chamber. When the central tube rotates, the installation plate drives the multiple scrapers to rotate, causing them to scrape the outer wall of the filter cartridge, removing impurities trapped on the outer wall and preventing the filter micropores of the filter cartridge from becoming clogged. The solution containing a large amount of impurities between the filter cartridge and the reaction vessel is discharged through the discharge pipe.

[0008] Preferably, it also includes an inner tube, an inner inlet, an inner lower outlet, a three-way valve, a rotary joint, a first delivery pipe, and a discharge pipe. The inner tube is rotatably mounted on the inner wall of the middle tube. An inner inlet is provided on the upper side wall of the inner tube, aligned with the inlet. An inner lower outlet is provided on the lower side wall of the inner tube. A lower opening is provided on the lower side wall of the middle tube, located at the bottom of the filter cartridge and aligned with the inner lower outlet. The outlet at the lower end of the middle tube is connected to channel one of the three-way valve via a rotary joint. Channel two of the three-way valve is connected to the first delivery pipe, and channel three of the three-way valve is connected to the discharge pipe. During normal operation, the inner lower outlet at the lower part of the inner tube... The inner tube is offset from the lower opening of the middle tube, and the inner inlet of the inner tube is aligned with the inlet. At this time, the specific enzyme particles will not be discharged through the middle tube and the inner tube. The solution containing anti-flocculation chitosan oligosaccharide can enter the middle tube through the inner inlet and the inlet and be fed into the three-way valve, and then be discharged through the delivery pipe. When it is necessary to discharge the specific enzyme particles, the inner tube is rotated relative to the middle tube so that the lower inner opening is aligned with the lower opening of the middle tube, and the inner inlet of the inner tube is offset from the inlet. At this time, the solution and the specific enzyme particles enter the inner tube and the middle tube through the lower inner opening and the lower opening and are fed into the three-way valve, and then be discharged through the discharge pipe, which facilitates the discharge of the specific enzyme particles.

[0009] Preferably, the device further includes a hopper, an inner discharge port, and a conical baffle. The hopper is installed at the upper end of the inner tube and is located above the reaction vessel. An inner discharge port is provided at the upper part of the inner tube. An upper opening is provided on the upper side wall of the middle tube and is located at the upper part of the filter cartridge, aligned with the inner discharge port. A conical baffle is installed inside the inner tube and is located between the inner liquid inlet and the inner discharge port. When it is necessary to add specific enzyme particles to the filter cartridge, the specific enzyme particles are added to the inner tube through the hopper. The conical baffle blocks the specific enzyme particles and guides them to the inner discharge port, so that the specific enzyme particles are discharged into the filter cartridge through the inner discharge port and the upper opening of the middle tube, thereby achieving the renewal of specific enzyme particles.

[0010] Preferably, it also includes a vent cap, which is installed on the reaction vessel and has its inlet end connected to the inside of the filter cartridge; the vent cap allows air and waste gas generated during the reaction to be discharged from the filter cartridge, preventing the formation of an air cushion layer on the upper part of the filter cartridge from affecting the discharge of the solution.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the raw material is input into the reaction chamber between the inside of the reaction tank and the outer wall of the filter tube through the inlet pipe. After being filtered by the micropores of the filter tube, the raw material comes into contact with the specific enzyme particles, thereby enzymatically hydrolyzing and preparing anti-flocculating chitosan oligosaccharide. The solution containing anti-flocculating chitosan oligosaccharide enters the middle tube through the inlet and is discharged from the reaction tank through the outlet. During this process, the middle tube rotates, which drives multiple stirrers to rotate. The multiple stirrers stir the specific enzyme particles and the raw material, making the contact more thorough and improving the reaction efficiency. Impurities in the raw material are filtered and intercepted by the micropores of the filter tube, avoiding contamination of the specific enzyme particles, maintaining the activity of the specific enzyme particles, and improving the preparation efficiency of anti-flocculating chitosan oligosaccharide.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0019] like Figures 1 to 5As shown, an anti-flocculation chitosan oligosaccharide preparation device includes a reaction tank 1 and an inlet pipe 2. The reaction tank 1 has a reaction chamber inside, and the inlet end of the inlet pipe 2 extends into the reaction chamber of the reaction tank 1. It also includes a filter cylinder 3, a central tube 4, multiple stirrers 5, an inlet port 6, and an outlet port 7. The filter cylinder 3 is installed in the reaction chamber of the reaction tank 1, and its side wall has micropores. Specific enzyme particles are filled inside the filter cylinder 3. The central tube 4 rotatably and vertically penetrates the reaction tank 1 and the filter cylinder 3. The central tube 4 is rotatably connected to the top and bottom walls of the reaction tank 1. Wear-resistant sealing rings are provided between the central tube 4 and the top and bottom walls of the reaction tank 1. Multiple stirrers 5 are installed on the outer wall of the central tube 4, located inside the filter cylinder 3. The inlet port 6 is located on the upper side wall of the central tube 4, inside the filter cylinder 3, and above the micropores of the filter cylinder 3. The lower end of the central tube 4... The reactor includes an outlet 7 located below the reaction vessel 1; a motor 8, a drive wheel 9, a driven wheel 10, and a transmission belt 11; the motor 8 is mounted on the reaction vessel 1, with the output shaft of the motor 8 concentrically mounted on the drive wheel 9; the driven wheel 10 is concentrically mounted on the central tube 4; and the transmission belt 11 is fitted onto the drive wheel 9 and the driven wheel 10; a mounting plate 12, multiple scrapers 13, and a discharge pipe 25 are also included. The mounting plate 12 is mounted on the outer wall of the central tube 4 and is located inside the reaction chamber of the reaction vessel 1, below the filter cartridge 3; multiple scrapers 13 are mounted on the mounting plate 12 and scrape the outer wall of the filter cartridge 3; the discharge pipe 25 is mounted on the reaction vessel 1, with its input end extending into the bottom of the reaction chamber of the reaction vessel 1; and a vent cap 24 is also included, mounted on the reaction vessel 1, with its input end communicating with the interior of the filter cartridge 3.

[0020] During operation, the raw material is fed into the reaction chamber between the inside of the reaction tank 1 and the outer wall of the filter cylinder 3 through the inlet pipe 2. After being filtered through the micropores of the filter cylinder 3, the raw material comes into contact with specific enzyme particles, thereby enzymatically hydrolyzing and preparing anti-flocculating chitosan oligosaccharide. The solution containing anti-flocculating chitosan oligosaccharide enters the middle tube 4 through the inlet 6 and is discharged from the reaction tank 1 through the outlet 7. During this process, the motor 8 drives the drive wheel 9 to rotate, and the drive wheel 9 drives the driven wheel 10 to rotate through the transmission belt 11. The driven wheel 10 drives the middle tube 4 to rotate, and the middle tube 4 drives multiple stirrers 5 to rotate. The multiple stirrers 5 stir the specific enzyme particles and raw materials, making the contact more thorough and improving the reaction efficiency. The air and waste gas generated during the reaction are discharged from the filter cylinder 3 through the vent cap 24, preventing the formation of an air cushion layer on the upper part of the filter cylinder 3 from affecting the solution discharge. Impurities in the raw materials are filtered and intercepted by the micropores of the filter cylinder 3. When the central tube 4 rotates, the mounting plate 12 drives multiple scrapers 13 to rotate, causing multiple scrapers 13 to scrape the outer wall of the filter cylinder 3 and scrape off the impurities intercepted on the outer wall of the filter cylinder 3, preventing the micropores of the filter cylinder 3 from clogging. The solution containing a large amount of impurities between the filter cylinder 3 and the reaction tank 1 is discharged through the residual discharge pipe 25, preventing impurities from contaminating the specific enzyme particles, maintaining the activity of the specific enzyme particles, and improving the preparation efficiency of anti-flocculation chitosan oligosaccharide. Example 2

[0021] like Figure 4 and Figure 5 As shown, based on Embodiment 1, it also includes an inner tube 14, an inner inlet 15, an inner lower outlet 16, a three-way valve 17, a rotary joint 18, a delivery pipe 19, and a discharge pipe 20. The inner tube 14 is rotatably mounted on the inner wall of the middle tube 4. The inner inlet 15 is provided on the upper side wall of the inner tube 14, and the inner inlet 15 is aligned with the inlet 6. The inner lower outlet 16 is provided on the lower side wall of the inner tube 14. The lower opening is provided on the lower side wall of the middle tube 4. The lower opening is located at the bottom of the filter cylinder 3 and is aligned with the inner lower outlet 16. The outlet 7 at the lower end of the middle tube 4 is connected to the channel of the three-way valve 17 by a rotary joint. The adapter 18 is connected, the second channel of the three-way valve 17 is connected to the first liquid delivery pipe 19, and the third channel of the three-way valve 17 is connected to the discharge pipe 20; it also includes a hopper 21, an inner discharge port 22 and a conical baffle 23. The hopper 21 is installed at the upper end of the inner tube 14. The hopper 21 is located above the reaction tank 1. The inner discharge port 22 is provided at the upper part of the inner tube 14. The upper side wall of the middle tube 4 is provided with an upper opening. The upper opening is located at the upper part of the filter cylinder 3 and is aligned with the inner discharge port 22. The conical baffle 23 is installed inside the inner tube 14. The conical baffle 23 is located between the inner liquid inlet 15 and the inner discharge port 22.

[0022] During normal operation, the lower inner port 16 of the inner tube 14 is offset from the lower opening of the middle tube 4, and the inner inlet 15 of the inner tube 14 is aligned with the inlet 6. At this time, the specific enzyme particles will not be discharged through the middle tube 4 and the inner tube 14. The solution containing anti-flocculation chitosan oligosaccharide can enter the middle tube 4 through the inner inlet 15 and the inlet 6, be fed into the three-way valve 17, and then discharged through the delivery pipe 19. When it is necessary to discharge the specific enzyme particles, the inner tube 14 is rotated relative to the middle tube 4 so that the lower inner port 16 is aligned with the lower opening of the middle tube 4, and the inner inlet 15 of the inner tube 14 is aligned with the inlet 6. 5 is offset from the inlet 6. At this time, the solution and specific enzyme particles enter the inner tube 14 and the middle tube 4 through the lower inlet 16 and the lower opening, and are fed into the three-way valve 17, and discharged through the discharge pipe 20, which facilitates the discharge of specific enzyme particles. When it is necessary to add specific enzyme particles to the filter cartridge 3, the specific enzyme particles are added to the inner tube 14 through the hopper 21. The conical baffle 23 blocks the specific enzyme particles and guides them to the inner outlet 22, so that the specific enzyme particles are discharged into the filter cartridge 3 through the inner outlet 22 and the upper opening of the middle tube 4, thereby realizing the renewal of specific enzyme particles.

[0023] like Figures 1 to 5 As shown, this utility model discloses an anti-flocculation chitosan oligosaccharide preparation device. During operation, the raw material is first input into the reaction chamber between the inside of the reaction tank 1 and the outer wall of the filter cylinder 3 through the inlet pipe 2. After being filtered through the micropores of the filter cylinder 3, the raw material comes into contact with specific enzyme particles, thereby enzymatically hydrolyzing and preparing anti-flocculation chitosan oligosaccharides. The solution containing the anti-flocculation chitosan oligosaccharides enters the middle pipe 4 through the inlet 6 and exits the reaction tank 1 through the outlet 7. During this process, the motor 8 drives the drive wheel 9 to rotate, which in turn drives the driven wheel 10 to rotate via the transmission belt 11. The driven wheel 10 drives the middle pipe 4 to rotate, which in turn drives multiple stirrers 5 to rotate. The multiple stirrers 5 stir the specific enzyme particles and the raw material, ensuring more thorough contact and improving reaction efficiency. Impurities in the raw materials are filtered and intercepted by the micropores of the filter cartridge 3, preventing contamination of the specific enzyme particles. Finally, when it is necessary to replace the specific enzyme particles, the inner tube 14 is rotated relative to the middle tube 4 so that the inner lower opening 16 is aligned with the lower opening of the middle tube 4, and the inner liquid inlet 15 on the inner tube 14 is offset from the liquid inlet 6. At this time, the solution and the specific enzyme particles enter the inner tube 14 and the middle tube 4 through the inner lower opening 16 and the lower opening, and are fed into the three-way valve 17 and discharged through the discharge pipe 20. The specific enzyme particles are added into the inner tube 14 through the hopper 21, and the conical baffle 23 blocks the specific enzyme particles and guides them to the inner discharge port 22, so that the specific enzyme particles are discharged into the filter cartridge 3 through the inner discharge port 22 and the upper opening of the middle tube 4, thereby realizing the replacement of the specific enzyme particles.

[0025] 1. The filter cartridge 3 is used to confine the specific enzyme particles, so that the specific enzyme particles will not be discharged with the reaction solution;
