Description

Technical Field

[0001] This invention belongs to the field of reaction vessels, and more specifically, relates to a reaction vessel for the synthesis of micro-crosslinked polymer high heat-resistant and flame-retardant resins. Background Technology

[0002] Micro-crosslinked high-heat-resistant and flame-retardant polymer resin is a high-performance polymer material that forms a slight network structure between polymer chains through controllable covalent bonds and introduces a heat-resistant skeleton and flame-retardant elements. It not only has high thermal stability but also excellent flame-retardant properties. Currently, in the synthesis and processing of micro-crosslinked polymer high heat-resistant and flame-retardant resins, a reaction vessel is typically used to heat and mix various material particles and solvents required for the synthesis of micro-crosslinked polymer high heat-resistant and flame-retardant resins. This allows the material particles to fully dissolve in the solvent and undergo a synthesis reaction. However, the mixing and stirring rack of a traditional reaction vessel is fixed in a structural position on the outside of the rotating rod. The mixing and stirring rack can only perform horizontal circular motion stirring in a fixed height area inside the vessel. As a result, the stirring coverage area of ​​a traditional reaction vessel is limited, and there is a stirring blind zone at the bottom of the vessel. Material accumulates, settles, and agglomerates at the bottom of the vessel, making it difficult to dissolve quickly into the reaction solvent. In addition, the structure and position of the injection port of a traditional reaction vessel are fixed, and the injection port cannot evenly disperse the material inside the vessel during the material injection process. This prolongs the material dispersion and stirring time of the stirring rack and reduces the overall synthesis reaction efficiency of micro-crosslinked polymer high heat-resistant and flame-retardant resins. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a reaction vessel for the synthesis of micro-crosslinked polymer high heat-resistant and flame-retardant resins, thereby solving the problems of limited stirring coverage area and blind stirring zones in traditional reaction vessels, as well as the inability of the injection port to uniformly disperse materials inside the vessel during material injection.

[0007] Furthermore, the turntable has a circular disc structure, and a pushing column is welded to the lower side of the circular disc structure near the outer edge. The pushing column is cylindrical and is inserted into the long strip-shaped through groove of the carriage.

[0008] Furthermore, the outer side of the rotating column is provided with two sets of long strip-shaped protrusions, and a reflux cylinder is welded to the outer side of the rotating column near the bottom.

The inclined plates of the reflux cylinder are arranged in a ring array around the vertical central axis of the reflux cylinder, and the reflux cylinder and the stirring rod are vertically opposite each other.

[0009] Furthermore, the lifting cylinder is a cylindrical structure that runs vertically through the top and bottom. A rotating cylinder is rotatably connected to the inner side of the lifting cylinder. The rotating cylinder is also a cylindrical structure that runs vertically through the top and bottom. The inner side of the cylindrical structure of the rotating cylinder is provided with two sets of vertically through opening grooves. The two sets of elongated protrusions of the rotating column are respectively embedded in the two sets of opening grooves of the rotating cylinder.

[0011] Furthermore, a cover plate is bolted to the bottom of the vessel lid, a pressure sensor is installed on the lower side of the cover plate, and a temperature sensor is installed on the inner side of the vessel lid.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, on the one hand, the rotating disk welded to the bottom of the drive rod is driven by a lifting motor to rotate, so that the push column welded to the bottom of the rotating disk pushes the long strip-shaped through groove wall structure of the slide, and the slide drives the lifting cylinder to move vertically up and down through the pull rod hinged to the bottom of the slider, which carries the stirring rod welded to the outer side of the rotating cylinder. On the other hand, the stirring motor drives the drive gear to form a meshing transmission structure at the outer tooth structure of the injection pipe ring plate, so that the injection pipe drives the long strip-shaped protrusion of the rotating column to drive the stirring rod welded to the outer side of the rotating cylinder to rotate horizontally, realizing the rotational stirring during the up and down sliding process of the stirring rod. This abandons the horizontal stirring structure with a fixed height position of the traditional reaction vessel stirring and mixing structure, increases the stirring coverage of the stirring rod on the material, and accelerates the mixing and dissolution efficiency of the material in the vessel.

[0013] 2. In this invention, on the one hand, the stirring motor drives the drive gear to form a meshing transmission structure at the outer tooth structure of the injection tube ring plate. The drive gear drives the L-shaped injection tube to rotate horizontally at the center of the top of the vessel. The L-shaped injection tube rotates and disperses the micro-crosslinked polymer high heat-resistant and flame-retardant resin synthetic material into the inside of the vessel. This eliminates the traditional fixed-point feeding structure, improves the uniformity of material distribution, and shortens the subsequent mixing time. On the other hand, the injection tube drives the counterflow cylinder welded to the outer side of the rotating column to rotate. The fourteen inclined plates of the counterflow cylinder agitate the solvent and pump the undissolved material to the stirring area of ​​the stirring rod for dissolution and mixing, avoiding the blind zone of stirring and mixing at the bottom of the vessel.

[0025] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0026] like Figures 1-10As shown, this invention provides a reaction vessel for the synthesis of micro-crosslinked polymer high heat-resistant and flame-retardant resin, including a column 2; a foot 1 is welded to the bottom end of the column 2, a frame 5 is welded to the outer side of the column 2, a control unit 4 is installed on the front side of the frame 5, and a support 16 is welded to the top end of the column 2; it also includes a vessel body 14 and a support cylinder 34; a shell 6 is welded to the outer side of the vessel body 14, an electric heating tube 35 is installed on the inner side of the shell 6, a support 16 is welded to the outer side of the vessel body 14, an electric discharge valve 3 is installed at the bottom end of the vessel body 14, a vessel cover 13 is bolted to the upper side of the vessel body 14, a stirring motor 12 is installed on the upper side of the vessel cover 13, and a motor shaft of the stirring motor 12 is mounted on the motor shaft. A transmission rod 33 is connected to a drive gear 32 at its bottom end; a material injection pipe 31 is rotatably connected to the inner side of the support cylinder 34, a rotating column 25 is welded to the bottom end of the material injection pipe 31, a scraper 7 is welded to the outer side of the rotating column 25, an electric feed valve 10 is installed at the top end of the support cylinder 34, a feed pipe 9 is bolted to the top end of the electric feed valve 10, and a kettle cover 13 is bolted to the bottom end of the support cylinder 34; a lifting motor 11 is installed on the upper side of the kettle cover 13, a drive rod 24 is installed on the motor shaft of the lifting motor 11, a turntable 21 is welded to the bottom end of the drive rod 24, a guide rod 17 is welded to the inner side of the kettle cover 13, and a slide 20 is slidably connected to the outer side of the guide rod 17.

[0027] In this embodiment of the invention, the injection tube 31 has an L-shaped tube structure. A ring plate is provided on the outer side of the L-shaped tube structure near the top. An external tooth structure is provided around the outer side of the ring plate of the injection tube 31. The drive gear 32 is meshed with the external tooth structure of the injection tube 31. During the process of the stirring motor 12 driving the drive gear 32 to rotate through the transmission rod 33, the drive gear 32 drives the injection tube 31 to rotate. The injection tube 31 rotates and sprinkles the material required for the synthesis of micro-crosslinked high-heat-resistant and flame-retardant polymer resin from the center of the top of the reactor body 14 into the inner side of the reactor body 14, so that the material is evenly distributed inside the reactor body 14 during the injection process, shortening the mixing time of the material inside the reactor body 14 and improving the mixing efficiency of the material and the solvent.

[0028] In this embodiment of the invention, a slider 23 is welded to the bottom end of the slide 20, and a pull rod 26 is hinged to the bottom end of the slider 23. A lifting cylinder 29 is hinged to the other end of the pull rod 26. A ring cover 30 is bolted to the top end of the lifting cylinder 29. A long strip-shaped through groove is provided on the upper side of the slide 20. A circular through hole is provided on the front side of the slide 20 near the left and right ends. Two sets of guide rods 17 are respectively inserted into the two sets of circular through holes of the slide 20. The two sets of guide rods 17 support the slide 20 and drive the slider 23 to slide horizontally back and forth, so that the slider 23 can stably pull the lifting cylinder 29 up and down through the pull rod 26.

[0029] In this embodiment of the invention, the turntable 21 has a circular disc structure. A pushing column 22 is welded to the lower side of the circular disc structure of the turntable 21 near the outer edge. The pushing column 22 has a cylindrical structure and is inserted into the elongated through groove of the slide 20. During the process of the lifting motor 11 driving the turntable 21 to rotate by driving the rotating rod 24, the pushing column 22 welded to the bottom end of the turntable 21 pushes the groove wall of the elongated through groove of the slide 20, so that the turntable 21 drives the slide 20 to move back and forth along the guide rod 17 through the pushing column 22. The slide 20 drives the pull rod 26 hinged to the bottom end of the slider 23 to rotate up and down. The pull rod 26 drives the lifting cylinder 29 to carry the stirring rod 27 welded to the outer side of the rotating cylinder 28 to move vertically back and forth along the rotating column 25, which replaces the traditional circumferential stirring motion of the stirring rod 27 on a fixed horizontal plane and increases the stirring range of the stirring rod 27.

[0030] In this embodiment of the invention, the outer side of the rotating column 25 is provided with two sets of elongated protruding plates. A reflux cylinder 8 is welded to the outer side of the rotating column 25 near the bottom. The inner side of the reflux cylinder 8 is provided with fourteen sets of inclined plate structures. The inclined plates of the reflux cylinder 8 are arranged in a ring array around the vertical central axis of the reflux cylinder 8. The reflux cylinder 8 and the stirring rod 27 are opposite each other. During the rotation of the reflux cylinder 8 driven by the rotating column 25, the vortex structure formed by the fourteen sets of inclined plates of the reflux cylinder 8 draws the material accumulated at the bottom of the vessel body 14 to the stirring rod 27 to participate in the stirring again, so as to avoid the undissolved material falling and settling and being unable to participate in the mixing and stirring reaction.

[0031] In this embodiment of the invention, the lifting cylinder 29 is a cylindrical structure that runs vertically through the interior. A rotating cylinder 28 is rotatably connected to the inner side of the lifting cylinder 29. The rotating cylinder 28 is also a cylindrical structure that runs vertically through the interior. The inner side of the cylindrical structure of the rotating cylinder 28 is provided with two sets of vertically through-hole grooves. Two sets of elongated protrusions of the rotating column 25 are respectively embedded in the two sets of grooves of the rotating cylinder 28. The rotating column 25, through the two sets of elongated protrusions embedded in the two sets of grooves of the rotating cylinder 28, ensures that the rotating cylinder 28, carrying the stirring rod 27, moves vertically up and down as the rotating column 25 rotates on the inner side of the lifting cylinder 29. This realizes the rotational stirring motion of the stirring rod 27 at different heights inside the vessel body 14.

[0032] In this embodiment of the invention, the scraper 7 has a J-shaped frame structure. The outer side of the J-shaped frame structure of the scraper 7 is provided with a silicone pad. The silicone pad of the scraper 7 is attached to the inner side of the vessel body 14. During the rotation of the scraper 7 driven by the rotating column 25, the silicone pad of the scraper 7 is attached to the inner wall of the vessel body 14 and rotates and scrapes, so that the scraper 7 scrapes off the material attached to the inner wall in real time, avoiding the situation where the material is attached to the heating part of the inner wall of the vessel body 14 for a long time and carbonization and agglomeration occurs.

[0033] In this embodiment of the invention, a cover plate 19 is bolted to the bottom of the vessel lid 13. A pressure sensor 18 is installed on the lower side of the cover plate 19, and a temperature sensor 15 is installed on the inner side of the vessel lid 13. The temperature sensor 15 and the pressure sensor 18 detect the temperature and pressure of the synthesis reaction of the micro-crosslinked polymer high heat-resistant and flame-retardant resin inside the vessel body 14. The temperature sensor 15 and the pressure sensor 18 transmit the temperature and pressure signals to the temperature and pressure detection module of the controller 4 through wires. The temperature and pressure detection module of the controller 4 analyzes the temperature and pressure values. If the temperature and pressure inside the vessel body 14 exceed the preset temperature range and pressure range, the temperature and pressure detection module of the controller 4 sends a stop command to the heating control module of the controller 4. The heating control module of the controller 4 controls the heating tube 35 to stop heating through wires. When the temperature and pressure inside the vessel body 14 are lower than the preset temperature and pressure range required for the reaction, the heating control module of the controller 4 controls the heating tube 35 to generate heat through wires, thereby realizing the automated maintenance of the temperature of the synthesis reaction of the micro-crosslinked polymer high heat-resistant and flame-retardant resin inside the vessel body 14.

[0034] Specific usage and functions of this invention: In the synthesis reaction of micro-crosslinked high-heat-resistant and flame-retardant polymer resin in a reactor, the operator inputs a feeding command through the control panel module of the control unit 4. The valve control module of the control unit 4 controls the opening of the electric feed valve 10 via a wire, and then injects the reaction solvent into the feed pipe 9. The reaction solvent flows along the feed pipe 9 and into the injection pipe 31 through the electric feed valve 10. The reaction solvent then flows into the reactor body 14 through the injection pipe 31. The motor control module of the control unit 4 controls the start of the stirring motor 12 via a wire. The stirring motor 12 drives the drive gear 32, which is welded to the bottom of the transmission rod 33, to rotate. Since the drive gear 32 is meshed with the external tooth structure on the outer side of the ring plate of the injection pipe 31, the drive gear 32 drives the injection pipe 31 to rotate. At this time, the operator pours the material into the feed pipe 9, and the material flows along the feed pipe 9 and into the injection pipe 31 through the electric feed valve 10. At this time, the material is evenly scattered through the rotating injection pipe 31. The mixture is fed into the reactor body 14. Then, the operator manipulates the control panel module of the control unit 4 to input heating and mixing reaction commands. The valve control module of the control unit 4 controls the electric feed valve 10 to close via wires. The heating control module of the control unit 4 controls the heating element 35 to generate heat via wires. The heating element 35 heats the reactor body 14. At this time, the temperature sensor 15 installed inside the reactor lid 13 and the pressure sensor 18 installed under the cover 19 continuously monitor the reaction temperature and pressure inside the reactor body 14. The temperature sensor 15 and pressure sensor 18 transmit the collected temperature and pressure signals to the temperature and pressure detection module of the control unit 4 in real time. The control unit 4 compares and analyzes the real-time parameters with the preset process parameters. When the temperature and pressure values ​​inside the reactor body 14 exceed the preset range, the temperature and pressure detection module of the control unit 4 sends a stop command to the heating control module of the control unit 4. The heating control module of the control unit 4 then controls the heating element 35 to stop heating via wires.When the temperature and pressure values ​​inside the reactor are lower than the preset range required by the process, the temperature and pressure detection module of the controller 4 sends a start command to the heating control module of the controller 4. The heating control module of the controller 4 starts the heating tube 35 through the wire, and the motor control module of the controller 4 starts the lifting motor 11 through the wire. The lifting motor 11 drives the drive rod 24 to drive the turntable 21 to rotate. At this time, the push column 22 welded to the bottom of the turntable 21 pushes the long strip-shaped through groove wall of the slide 20, causing the slide 20 to drive the slider 23 to move back and forth along the guide rod 17. The slider 23 drives the pull rod 26 hinged at the bottom to repeatedly push the lifting cylinder 29 up and down. The lifting cylinder 29 drives the rotating cylinder 28 connected to the inner side to move vertically up and down along the rotating column 25. The rotating cylinder 28, equipped with the stirring rod 27 welded to the outer side, moves up and down synchronously. At this time, the injection pipe 31 drives the rotating column 25 to rotate. Since the long strip-shaped protrusion of the rotating column 25 is embedded in the opening of the rotating cylinder 28... Inside the groove, the rotating column 25 drives the stirring rod 27, which is welded to the outer side of the rotating cylinder 28, to rotate horizontally. During rotation, the stirring rod 27 moves up and down to stir the reaction solvent and materials. Simultaneously, the rotating column 25 drives the countercurrent cylinder 8, which is welded to its outer side, to rotate. The fourteen sets of inclined plates on the inner side of the countercurrent cylinder 8 agitate the solvent, drawing the material deposited at the bottom of the reactor body 14 to the stirring rod 27 for mixing. The rotating column 25 drives the scraper 7, which is welded to its outer side, to rotate. The silicone pads adhered to the outer side of the scraper 7 scrape the inside of the reactor body 14. When the synthesis reaction of the micro-crosslinked polymer high-heat-resistant and flame-retardant resin in the reactor is complete, the operator inputs a discharge command through the control panel module of the control machine 4. The valve control module of the control machine 4 controls the electric discharge valve 3 to open via wires. The micro-crosslinked polymer high-heat-resistant and flame-retardant resin is discharged from the reactor body 14 through the electric discharge valve 3, thus completing the synthesis reaction of the micro-crosslinked polymer high-heat-resistant and flame-retardant resin in the reactor.

[0035] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies, and any method that achieves the desired beneficial effect can be implemented. The electric unloading valve 3, control unit 4, electric feed valve 10, lifting motor 11, stirring motor 12, temperature sensor 15, pressure sensor 18, and heating element 35 mentioned above are all common commercially available components.
