Description

A resin polymerization reactor Technical Field

[0001] This invention relates to the field of chemical reaction vessels, and more particularly to a resin polymerization reaction vessel. Background Technology

[0002] Resin polymerization refers to the process by which monomer molecules, through a chemical polymerization reaction under the influence of initiators, catalysts, temperature, pressure, and other conditions, form a high-molecular-weight polymer with repeating structural units. This process is the core step in resin production, determining the molecular weight, molecular structure, and final properties of the resin. Resin polymerization is mostly carried out using reaction vessels.

[0003] During the resin polymerization process, water needs to be injected into the raw materials in the reactor according to the process requirements. However, existing reactors generally use the method of injecting water from the top of the reactor. The injected water tends to accumulate in the upper layer of the raw materials and is difficult to penetrate downwards and make full contact with the lower layer of raw materials. This ultimately causes uneven distribution of moisture content between the upper and lower layers of the raw materials, which seriously affects the resin polymerization effect. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a resin polymerization reactor.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a resin polymerization reactor, comprising a reactor body and a motor, wherein a stirring shaft is coaxially rotatably mounted inside the reactor body, the stirring shaft extends through the bottom of the reactor body, and the bottom of the stirring shaft is connected to the motor; a water injection pipe is provided through the top of the reactor body; a connector for connecting the stirring shaft is provided above the interior of the reactor body; both ends of the connector are provided with drainage pipes; multiple extension pipes are linearly arrayed and fixedly connected on the drainage pipes; multiple through holes are linearly arrayed through the bottom of the extension pipes; a hole protector is provided on the extension pipes; the ends of the water injection pipe and the ends of the drainage pipes are connected to the connector; multiple stirring blades are linearly arrayed and fixedly mounted on the outer surface of the stirring shaft, and the stirring blades are staggered with the extension pipes.

Multiple connecting frames are linearly arrayed and fixedly installed at the lower end of the movable frame. Each of the multiple connecting frames has a stop cap fixedly installed at its end. The stop cap fits against the lower end of the protruding tube and is aligned with the through hole.

[0007] Preferably, a second piston is slidably installed inside the protruding tube near its end, and a second stopper rod extends from the side of the second piston. The second stopper rod passes through the end of the protruding tube and slides in cooperation with the protruding tube.

A limiting frame is fixedly installed on the outer surface of the protruding tube, and the movable frame is slidably installed on the outer surface of the limiting frame.

[0008] Preferably, the connecting component includes a connecting pipe coaxially and rotatably mounted inside the upper part of the reactor body. The upper end of the connecting pipe is rotatably connected to the end of the water injection pipe. The end of the drain pipe is fixedly connected to the outer surface of the connecting pipe near the lower edge. A piston is slidably mounted inside the connecting pipe. A stopper rod extends from the lower end of the piston. The stopper rod passes through the lower end of the connecting pipe. A shaft connector is fixedly mounted at the lower end of the stopper rod. A shaft connector groove is formed in the middle of the upper end of the stirring shaft. The shaft connector is located above the shaft connector groove.

[0009] Preferably, a carrier is slidably mounted on the outer surface of the connecting shaft insert. Two pipe supports extend symmetrically from the lower part of the outer surface of the carrier. Two drainage pipes are respectively fixed through and fixed to the ends of the two pipe supports. Two connecting rods are symmetrically arranged on the upper part of the outer surface of the carrier. A turntable is fixedly mounted between the upper ends of the two connecting rods. A rotating seat is rotatably mounted on the outer surface of the turntable. The rotating seat is connected to the reactor body. The connecting pipe is installed through and installed in the middle of the inner side of the turntable. A fixed ring is slidably mounted on the outer surface of each of the two connecting rods. The opposite ends of the two fixed rings are fixed to the connecting shaft insert. A lower toothed ring is fixedly mounted between the opposite ends of the two fixed rings. An upper toothed ring is engaged with the upper end of the lower toothed ring. The lower toothed ring is elastically connected to the pipe support.

[0010] Preferably, two fixing blocks extend symmetrically near the end of the tube frame. A guide shell is fixedly installed through the middle of the fixing block. A guide post is slidably installed inside the guide shell. The guide post extends through the upper end of the guide shell. The upper end of the guide post is fixed to the lower toothed ring. A top ring spring is fixedly installed on the inner bottom surface of the guide shell. The end of the top ring spring is fixed to the lower end of the guide post.

[0011] Preferably, a sleeve is coaxially fixedly installed on the inner surface of the turntable, the sleeve is fixed to the upper part of the outer surface of the connecting pipe, and two supports extend symmetrically from the upper inner wall of the reactor body, with the opposite ends of the two supports fixed to the turntable.

[0012] Preferably, a lug is fixedly installed at the lower end of the connecting rod, and the end of the lug is fixed to the carrier. A fixing post is fixedly installed at the lower end of the carrier, and the end of the fixing post is fixed to the upper toothed ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By using multiple extension tubes arranged in a linear array on the drainage pipe, the water addition points can be evenly distributed at different heights of the raw material. At the same time, the rotating stirring shaft drives the extension tubes on the drainage pipe to rotate in a circular motion, thereby continuously changing the position of the water injection point at the same height. This allows the water to be injected into the raw material in a multi-point, dispersed manner, ensuring uniform contact with the raw material and avoiding uneven mixing, thus improving the resin polymerization effect.

[0015] 2. During water injection, the stirring shaft rotates at low speed. Simultaneously, the No. 1 piston inside the connecting pipe moves downward under water pressure, causing the connecting shaft insert and the lower toothed ring to move downward, separating the lower and upper toothed rings. At the same time, the connecting shaft insert presses against the end face of the stirring shaft. When the stirring shaft rotates, aligning the connecting shaft groove and the connecting shaft insert, the connecting shaft insert, under water pressure, will insert into the connecting shaft groove, connecting the carrier and the stirring shaft. After insertion, the No. 1 piston is just below the drain pipe, allowing water from the connecting pipe to enter the drain pipe and exit through the through-hole on the extension pipe, thus being added to the raw materials. During this process… The stirring shaft drives the carrier to rotate, which in turn drives the drainage pipe to rotate. When water injection is completed and stops, the top ring spring will return to its original shape due to the loss of water pressure. This pushes the No. 1 piston, the lower toothed ring, and the connecting shaft block upwards, causing the connecting shaft block to separate from the stirring shaft. At the same time, the lower toothed ring re-engages with the upper toothed ring to fix the drainage pipe in place, preventing it from rotating. Thus, when the stirring blades on the stirring shaft agitate the raw materials, the drainage pipe and the extension pipe can block the raw materials, thereby creating a turbulent flow and increasing the stirring force to promote the mixing of the raw materials and further improve the resin polymerization effect.

[0016] 3. When water enters the extension pipe, the water pressure pushes the second piston, causing the moving frame to shift laterally. This displaces the baffle cap from below the through hole, allowing water to drain out through the through hole for injection. After injection, the return spring returns to its original shape due to the loss of water pressure, pushing the moving frame back to its original position. This causes the baffle cap to move back below the through hole to seal it, preventing raw materials from entering the through hole and causing blockage that could affect subsequent water injection. This ensures the smooth operation of the water injection process. Attached Figure Description

[0026] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] As shown in Figures 1-8, a resin polymerization reactor includes a reactor body 1 and a motor 3. A stirring shaft 2 is coaxially mounted inside the reactor body 1, extending from the bottom of the reactor body 1. The stirring shaft 2 stirs the raw materials. The bottom of the stirring shaft 2 is connected to the motor 3, which drives the stirring shaft 2 to rotate. A water injection pipe 4 is installed through the top of the reactor body 1. A connector for the stirring shaft 2 is installed above the interior of the reactor body 1. Both ends of the connector are connected to a drain pipe 5. Multiple extension pipes 6 are linearly arranged and fixedly connected to the drain pipes 5, which introduce water into the extension pipes 6. Multiple through holes 3 are linearly arranged through the bottom of the extension pipes 6. 6. A protective hole is provided on the protruding pipe 6. The end of the water injection pipe 4 and the end of the drainage pipe 5 are connected to the connecting part. Multiple stirring blades 7 are fixedly installed in a linear array on the outer surface of the stirring shaft 2. The stirring blades 7 and the protruding pipe 6 are staggered to ensure that the stirring blades 7 and the protruding pipe 6 will not obstruct each other. Through the multiple protruding pipes 6 arranged in a linear array on the drainage pipe 5, the water addition points can be evenly distributed at different heights of the raw material. At the same time, the rotating stirring shaft 2 drives the protruding pipes 6 on the drainage pipe 5 to rotate in a circle to continuously change the position of the water injection point at the same height. This allows the water to be injected into the raw material in a multi-point and dispersed state, so that it comes into uniform contact with the raw material and avoids uneven mixing, thereby improving the resin polymerization effect.

[0028] The hole protector includes a movable frame 8, which is elastically connected to the extension tube 6. Multiple connecting frames 9 are linearly arrayed and fixedly installed at the lower end of the movable frame 8. Each end of the multiple connecting frames 9 is fixedly installed with a stop cap 10. The connecting frame 9 serves to fix the stop cap 10 and the movable frame 8 together. The stop cap 10 fits against the lower end of the extension tube 6 and is aligned with the through hole 36. The stop cap 10 can block and seal the through hole 36.

[0029] A second piston 35 is slidably mounted inside the extension tube 6 near its end. A second stopper rod 33 extends from the side of the second piston 35. The second piston 35 can be pushed by water pressure, thereby driving the moving frame 8 to move. The second stopper rod 33 extends through the end of the extension tube 6 and slides with the extension tube 6, serving as a connection. A return spring 34 is wound around the outside of the second stopper rod 33. The two ends of the return spring 34 are fixed to the second piston 35 and the inner end face of the extension tube 6, respectively. The return spring 34 drives the second piston 35 to return to its original position. A limiting frame 11 is fixedly mounted on the outer surface of the extension tube 6, and the moving frame 8 slides... The movable frame 8 is mounted on the outer surface of the limiting frame 11. The limiting frame 11 guides the movable frame 8. When water enters the extension pipe 6, the water pressure pushes the second piston 35, which in turn moves the movable frame 8 to the side, causing the stop cap 10 to disengage from below the through hole 36, allowing water to be discharged from the through hole 36 for water injection. After water injection, due to the loss of water pressure, the return spring 34 will return to its original shape, pushing the movable frame 8 to reset, and then moving the stop cap 10 back to below the through hole 36 to seal it, so as to prevent raw materials from entering the through hole 36 and causing blockage that affects subsequent water injection, thus ensuring the smooth progress of the water injection operation.

[0030] The fitting includes a connecting pipe 16 coaxially rotatably mounted inside the reactor body 1. The upper end of the connecting pipe 16 is rotatably connected to the end of the water injection pipe 4, ensuring normal rotation of the connecting pipe 16 and the drainage pipe 5. The end of the drainage pipe 5 is fixedly connected to the outer surface of the connecting pipe 16 near the lower edge. A piston 31 is slidably mounted inside the connecting pipe 16. A stopper rod 32 extends from the lower end of the piston 31 and serves as a connector. The stopper rod 32 passes through the lower end of the connecting pipe 16. A shaft connector 23 is fixedly mounted at the lower end of the stopper rod 32. A shaft connector groove 22 is provided in the middle of the upper end of the stirring shaft 2. The shaft connector 23 is located above the shaft connector groove 22. The fit between the shaft connector 23 and the shaft connector groove 22 serves to connect with the stirring shaft 2.

[0031] A carrier 25 is slidably mounted on the outer surface of the connecting shaft insert 23. Two pipe supports 20 extend symmetrically from the lower part of the outer surface of the carrier 25. Two drainage pipes 5 are respectively fixed to the ends of the two pipe supports 20. The pipe supports 20 serve to fix the drainage pipes 5. Two connecting rods 17 are symmetrically arranged on the upper part of the outer surface of the carrier 25. A turntable 12 is fixedly mounted between the upper ends of the two connecting rods 17. The connecting rods 17 serve to fix the turntable 12 and the carrier 25 together. A rotating seat 13 is rotatably mounted on the outer surface of the turntable 12. The rotating seat 13 serves to support the turntable 12. The rotating seat 13 is connected to the reactor body 1. A connecting pipe 16 is installed through the inner part of the turntable 12. On the side center, two connecting rods 17 are slidably mounted with fixed ring frames 18 on their outer surfaces. The opposite ends of the two fixed ring frames 18 are fixed to the connecting shaft insert 23. A lower toothed ring 21 is fixedly installed between the opposite ends of the two fixed ring frames 18. The fixed ring frames 18 serve to fix the lower toothed ring 21 and the connecting shaft insert 23 together. The upper end of the lower toothed ring 21 is engaged with an upper toothed ring 19. The engagement of the lower toothed ring 21 and the upper toothed ring 19 can fix the drainage pipe 5 so that it cannot rotate. Thus, when the stirring blades 7 on the stirring shaft 2 agitate the raw material, the drainage pipe 5 and the extension pipe 6 can block the raw material to play a turbulence role. The lower toothed ring 21 is elastically connected to the pipe frame 20.

[0032] Two fixing blocks 28 extend symmetrically near the end of the pipe rack 20. A guide shell 27 is fixedly installed through the middle of the fixing block 28, which serves to fix the guide shell 27. A guide post 26 is slidably installed inside the guide shell 27, extending from the upper end of the guide shell 27. The upper end of the guide post 26 is fixed to the lower toothed ring 21. The guide shell 27 and the guide post 26 serve to guide the lower toothed ring 21. A top ring spring 30 is fixedly installed on the bottom surface inside the guide shell 27. Spring 30 serves to push components such as the lower toothed ring 21 upwards and reset. The end of the top ring spring 30 is fixed to the lower end of the guide post 26. When water is injected, the stirring shaft 2 rotates at low speed, and at the same time, the first piston 31 in the connecting pipe 16 moves downwards under the pressure of water, thereby driving the connecting shaft insert 23 and the lower toothed ring 21 downwards, causing the lower toothed ring 21 and the upper toothed ring 19 to separate. At the same time, the connecting shaft insert 23 presses against the end face of the stirring shaft 2. When the stirring shaft 2 rotates, the connecting shaft groove 22 and the connecting shaft insert 23... During alignment, the connecting block 23, driven by water pressure, will insert into the connecting groove 22 to connect the carrier 25 and the stirring shaft 2. Simultaneously, after insertion, the first piston 31 will be just below the drain pipe 5, allowing water from the connecting pipe 16 to enter the drain pipe 5 and exit through the through hole 36 on the extension pipe 6, thus being added to the raw materials. During this process, the stirring shaft 2 will drive the carrier 25 to rotate, thereby driving the drain pipe 5 to rotate. When water injection is complete and stops, the top ring spring 3 will stop due to the loss of water pressure. The piston 0 will recover its deformation, pushing the piston 31, the lower toothed ring 21, and the connecting block 23 upward, causing the connecting block 23 to separate from the stirring shaft 2. At the same time, the lower toothed ring 21 re-engages with the upper toothed ring 19 to fix the drain pipe 5, preventing it from rotating. Thus, when the stirring blade 7 on the stirring shaft 2 agitates the raw material, the drain pipe 5 and the extension pipe 6 can block the raw material, thereby playing a turbulent role, increasing the stirring force, promoting the mixing of the raw material, and further improving the resin polymerization effect.

[0033] A sleeve 15 is coaxially fixed on the inner surface of the turntable 12. The sleeve 15 is fixed to the upper part of the outer surface of the connecting pipe 16. The sleeve 15 serves to facilitate the fixing of the connecting pipe 16 and the turntable 12 together. Two supports 14 extend symmetrically from the upper inner wall of the reactor body 1. The opposite ends of the two supports 14 are fixed to the rotating seat 13. The supports 14 serve to fix the rotating seat 13.

[0034] A lug 24 is fixedly installed at the lower end of the connecting rod 17. The end of the lug 24 is fixed to the carrier 25. The lug 24 serves to fix the connecting rod 17 and the carrier 25 together. A fixing post 29 is fixedly installed at the lower end of the frame 14. The end of the fixing post 29 is fixed to the upper toothed ring 19. The cooperation between the fixing post 29 and the frame 14 can fix the upper toothed ring 19 and the reactor body 1 together.

[0035] During operation, the raw materials are added to the reactor body 1 through the feeding pipe at the top of the reactor body 1. Then, the motor 3 drives the stirring shaft 2 to rotate, and the reactor body 1 is heated to carry out the resin polymerization reaction. When water is added during the process, the stirring shaft 2 rotates at a low speed, and the water is pressurized by the water pump and sent into the connecting pipe 16 through the water injection pipe 4. At this time, the first piston 31 in the connecting pipe 16 will move downward under the push of the water pressure, which will drive the connecting shaft insert 23 and the lower toothed ring 21 to move downward, so that the lower toothed ring 21 and the upper toothed ring 19 are separated. At the same time, the connecting shaft insert 23 presses against the stirring shaft. On the end face of 2, when the stirring shaft 2 rotates, aligning the shaft connecting groove 22 and the shaft connecting block 23, the shaft connecting block 23, under the push of water pressure, will insert into the shaft connecting groove 22 to connect the carrier 25 and the stirring shaft 2. Simultaneously, after insertion, the first piston 31 is just below the drain pipe 5, allowing water in the connecting pipe 16 to enter the multiple extension pipes 6 on the drain pipe 5. At this time, the second piston 35 in the extension pipe 6 is pushed by water pressure, thereby causing the moving frame 8 to move laterally, causing the baffle cap 10 to disengage from below the through hole 36, allowing water to drain from the through hole 36 for water injection. During this process, the stirring shaft 2 drives the carrier 25 to rotate, which in turn drives the extension pipe 6 on the diversion pipe 5 to rotate in a circular motion, continuously changing the position of the water injection point at the same height. This allows the water to be injected into the raw material in a multi-point, dispersed manner, ensuring uniform contact with the raw material. When the water injection is completed and stops, the top ring spring 30 and the return spring 34 will return to their original shape due to the loss of water pressure. The returned spring 34 will push the moving frame 8 to return to its original position, thereby moving the baffle cap 10 back to below the through hole 36 to seal it and prevent the raw material from entering the through hole 36. If blockage occurs within 6, affecting subsequent water injection, the top ring spring 30, which has recovered its deformation, will push the first piston 31, the lower toothed ring 21, and the connecting shaft block 23 upward, causing the connecting shaft block 23 to separate from the stirring shaft 2. At the same time, the lower toothed ring 21 will re-engage with the upper toothed ring 19 to fix the drain pipe 5, preventing it from rotating. Thus, when the stirring blade 7 on the stirring shaft 2 agitates the raw materials, the drain pipe 5 and the extension pipe 6 can block the raw materials, thereby playing a turbulent role, increasing the stirring force, promoting the mixing of raw materials, and improving the resin polymerization effect.
