Description

Technical Field

[0001] This invention belongs to the technical field of reaction apparatus, and more specifically, it is a temperature-controlled polymerization reaction apparatus for chemical applications. Background Technology

[0002] Polymerization is the process of converting low-molecular-weight monomers into high-molecular-weight polymers. Polymers possess important properties that low-molecular-weight monomers lack, such as plasticity, fiber formation, film formation, and high elasticity. They can be widely used as polymeric materials for plastics, fibers, rubber, coatings, adhesives, and other applications. These materials are composed of one or more structural units (monomers) and are polymeric compounds synthesized from monomers through repeated reactions.

[0003] Patent document CN105032323B discloses a polymerization reactor apparatus, comprising: a reactor, a condensation system, a pre-reaction system, and a digital control system. The reactor is used for the polymerization reaction; the condensation system is connected to the reactor and is used for gas-liquid separation of the reaction products in the reactor under normal or negative pressure; the pre-reaction system is used to detect the physicochemical properties of the prepolymer and adjust the equivalence ratio of each component in the prepolymer solution; the digital control system is used to control the temperature, gas flow rate and volume, and pressure of the reactor, and also controls the temperature of the pre-reaction system. This apparatus is used for polycondensation reactions and copolymer preparation reactions requiring prepolymers. This apparatus at least partially solves the problems of how to achieve batch preparation of experimental-grade polymers in a laboratory environment and how to achieve perfect process control.

[0004] Traditional polymerization reactors have several shortcomings. Firstly, they lack temperature control mechanisms, relying primarily on steam heating. This simplistic design also lacks rapid pressure relief mechanisms. Furthermore, the initiators used in polymerization are highly reactive peroxides, which, if the batching ratio is not properly controlled, can easily lead to explosive polymerization, causing a sudden increase in reactor pressure and potentially resulting in an explosion, thus posing a safety risk. Secondly, the absence of auxiliary feeding mechanisms in traditional reactors causes raw materials to accumulate during feeding, leading to uneven mixing during subsequent stirring. Additionally, the high molecular weight and viscosity of polymers make it difficult to dissipate the heat of polymerization. In the event of water or power outages or stirring malfunctions, these polymers can easily adhere to the reactor walls and cause blockages, resulting in localized overheating or reactor overheating and potentially explosions. Finally, the simplistic mixing structure of traditional reactors increases the time required for mixing and stirring, and the inability to fully contact the materials with heat further increases the heating time, resulting in poor overall performance. Summary of the Invention

[0005] The purpose of this invention is to provide a temperature-controlled polymerization reactor for chemical applications, which can solve existing problems.

[0006] The problem solved by this invention is:

[0007] 1. Traditional polymerization reactors do not have a temperature regulation structure and are mainly heated by steam. They have a simple structure and do not have a rapid pressure relief structure. The initiators added in the polymerization reaction are all highly chemically active peroxides. If the feed ratio is not properly controlled, it is easy to cause explosive polymerization. The sudden increase in reactor pressure can easily cause an explosion, resulting in low safety.

[0008] 2. Traditional polymerization reactors do not have an auxiliary feeding structure, which causes the raw materials to accumulate during the feeding process. This makes it easy for uneven mixing to occur during subsequent mixing and stirring operations. At the same time, the polymer has a high molecular weight and high viscosity, and the heat of polymerization is not easy to dissipate. Once there is a water outage, power outage or stirring failure, it is easy to stick to the wall and blockage, causing local overheating or overheating of the reactor, and even explosion.

[0009] 3. Traditional polymerization reactors have a simple mixing structure, which increases the time required for mixing and stirring materials within the reactor. At the same time, heat cannot fully contact the materials, increasing the time required for heating the materials, resulting in poor performance.

[0010] The objective of this invention can be achieved through the following technical solutions:

[0011] A temperature-controlled polymerization reactor for chemical applications includes an inner cylinder, an outer cylinder, and a stirring rod. The inner cylinder is fixedly installed in the middle of the inner side of the outer cylinder. The stirring rod is movably installed in the middle of the inner cylinder. An electric heating tube is fixedly installed on the inner wall of the inner cylinder. Several sets of heat-conducting rings are fixedly installed on one side of the electric heating tube. A flow-diverting ring is fixedly installed on the upper part of the inner side of the inner cylinder. A circular top cover is movably installed at the upper end of the inner cylinder. The inner cylinder and the circular top cover are movably connected by a pneumatic push rod. The pneumatic push rod is fixedly installed on both outer surfaces of the inner cylinder. The outer cylinder has a hollow structure, and two sets of condensate inlets are fixedly installed on the lower outer surface of the outer cylinder.

[0012] As a further technical solution of the present invention, several sets of heat-conducting rings are connected and fixed together by a heat-conducting frame. The heat-conducting frame is fixedly installed at the upper and lower ends of the heat-conducting ring. The heat-conducting ring and the electric heating tube are connected by a heat-conducting rod. When the polymerization reaction device is in use, the heat generated by the electric heating tube during operation can be introduced into the heat-conducting ring by the heat-conducting rod. The heat-conducting ring adopts a ring structure design as a whole. The heat-conducting ring is immersed in the material inside the inner cylinder. At the same time, the heat-conducting frame makes multiple heat-conducting rings heat up at the same time, making the heating operation of the polymerization reaction device more uniform and shortening its heating time.

[0013] As a further technical solution of the present invention, a telescopic tube is provided at the lower middle position of the inner cylinder. The telescopic tube is provided with a plug inside. A feed nozzle is provided on the upper outer surface of the telescopic tube, and a discharge pipe is provided on the lower outer surface of the telescopic tube. A rotating bracket for use with a stirring rod is movably sleeved on the upper end of the feed nozzle. The rotating bracket provides support for the bottom of the stirring rod, reducing the friction when the stirring rod rotates. The user can open the discharge pipe by pulling down the telescopic tube, allowing the material in the inner cylinder to enter the telescopic tube through the feed nozzle and then be discharged through the discharge pipe.

[0014] As a further technical solution of the present invention, mixing rods are fixedly installed on both outer surfaces of the stirring rod, and a stirring frame is fixedly installed on the lower outer surface of the stirring rod. The stirring frame has a hollow structure inside. The stirring rod synchronously drives the mixing rod and the stirring frame to rotate. The stirring frame plays a mixing role on the material at the bottom of the inner cylinder. Secondly, the mixing rod can be used to mix the material in the middle and upper parts of the inner cylinder. The hollow structure design of the stirring frame can effectively reduce the resistance when the stirring frame rotates.

[0015] As a further technical solution of the present invention, the upper end of the stirring rod is movably sleeved with a rotating shaft, and the stirring rod and the circular top cover are movably connected through the rotating shaft. The upper end of the circular top cover is provided with a motor for driving the stirring rod. The outer side surface of the mixing rod is provided with a sloping scraper groove. The user starts the motor, which drives the stirring rod to rotate, so that the stirring rod synchronously drives the mixing rod and the stirring frame. When the mixing rod rotates, the sloping scraper groove can reduce the resistance when the mixing rod rotates.

[0016] As a further technical solution of the present invention, the upper end of the pneumatic push rod is movably sleeved with a telescopic rod for driving the circular top cover. The inner side of the pneumatic push rod is provided with a pressure valve, and a fixing ring for connecting to the upper end of the inner cylinder is fixedly installed on one side of the pneumatic push rod. When the pressure inside the inner cylinder is too high, the pressure valve inside the pneumatic push rod is automatically opened, so that the pneumatic push rod uses high-pressure gas to drive the telescopic rod, so that the telescopic rod quickly moves the circular top cover upward, thereby opening the circular top cover at the upper part of the inner cylinder, quickly releasing the pressure inside the inner cylinder, and preventing the inner cylinder from exploding.

[0017] As a further technical solution of the present invention, the overall diversion ring is a hollow annular structure. A T-shaped tube is fixedly installed on the inner side of the diversion ring, and a feed pipe for use with the T-shaped tube is fixedly installed on the upper end of the circular top cover. The user injects the material into the T-shaped tube through the feed pipe and pours the material into the diversion ring through the T-shaped tube. The diversion ring is used to divert the material, so that the material is evenly discharged into the inner cylinder, thereby improving the mixing effect.

[0018] As a further technical solution of the present invention, a diversion pipe is fixedly installed inside the diversion ring. The diversion pipe has an overall annular structure. Several sets of spray heads are fixedly installed at the lower part of the diversion pipe. A solenoid valve is provided in the middle of the T-shaped pipe, and a main discharge port is provided at the lower middle of the T-shaped pipe. The opening or closing of the T-shaped pipe can be controlled by the solenoid valve. When the solenoid valve is open, the material in the T-shaped pipe is directly discharged through the main discharge port. When the solenoid valve is closed, the material in the T-shaped pipe is discharged through the spray head. The user can control the opening and closing of the solenoid valve according to the material type.

[0019] As a further technical solution of the present invention, a hand hole is provided on the upper outer surface of the circular top cover, and a thermometer hole is provided on the side of the upper outer surface of the circular top cover near the hand hole.

[0020] As a further technical solution of the present invention, a fixed bracket is fixedly installed at the lower part of the outer surface of the outer cylinder, and a circular groove for use with telescopic pipe fittings is provided at the lower middle part of both the inner cylinder and the outer cylinder.

[0021] The beneficial effects of this invention are:

[0022] 1. By incorporating electric heating elements and a pneumatic actuator, this temperature-controlled polymerization reactor for chemical applications features multiple heating structures, including steam and electric heating. The electric heating element allows for direct temperature regulation, enabling precise control of the polymerization reactor's heating temperature. During operation, the user directly introduces the chemical material into the inner cylinder via the feed pipe. With a normal power supply, the electric heating element, in conjunction with a heat-conducting ring, heats the chemical material inside the inner cylinder. The user then starts the motor, which drives the stirring rod to rotate. The mixing rod and stirring frame are driven to mix and stir the chemical materials inside the inner cylinder. In conjunction with two sets of pneumatic push rods, the inner cylinder has a rapid pressure relief structure. Both sets of pneumatic push rods are connected to the sides of the inner cylinder. When the pressure inside the inner cylinder becomes too high, the air pressure valve inside the pneumatic push rod automatically opens, allowing the pneumatic push rod to use high-pressure gas to drive the telescopic rod. This telescopic rod quickly moves the circular top cover upwards, opening the top cover at the top of the inner cylinder and rapidly releasing the pressure inside, preventing an explosion and effectively improving the safety of the polymerization reactor.

[0023] 2. By incorporating an outer cylinder and a flow divider ring, this temperature-controlled polymerization reactor for chemical use allows for continuous heating of the inner cylinder via steam even during power outages. This prevents blockages and build-up on the inner cylinder due to power failures. During operation, the user introduces high-temperature steam into the outer cylinder through its inlet. The outer cylinder completely encloses the outer surface of the inner cylinder, enabling steam heating. Condensate generated during heating is discharged directly through the condensate outlet. Furthermore, the flow divider ring allows for precise control of raw material input based on its type. By implementing a reasonable flow distribution operation, various raw materials are thoroughly mixed. During operation, the user injects the material into the T-tube through the feed pipe, and then pours the material into the flow distribution ring through the T-tube. The flow distribution ring distributes the material evenly into the inner cylinder, improving the mixing effect. The opening and closing of the T-tube can be controlled by a solenoid valve. When the solenoid valve is open, the material in the T-tube is discharged directly through the main outlet. When the solenoid valve is closed, the material in the T-tube is discharged through the spray head. The user can control the opening and closing of the solenoid valve according to the material type, thus ensuring that the polymerization reactor has an auxiliary flow distribution structure, making the material mixing more thorough.

[0024] 3. By incorporating a stirring frame and heat-conducting rings, this temperature-controlled polymerization reactor allows users to utilize the stirring frame and stirring rod to create a multi-stage mixing structure, ensuring thorough mixing of the bottom and top of the reactor. The heat-conducting rings further enhance heat distribution within the inner cylinder, reducing heating time. During operation, the motor drives the stirring rod, which in turn rotates the mixing rod and stirring frame. The inclined scraper reduces resistance during rotation, and the hollow design of the stirring frame minimizes resistance. The heat-conducting rods transfer heat from the heating elements to the heat-conducting rings, which are fully immersed in the material within the inner cylinder. The heat-conducting frame ensures simultaneous heating of multiple rings, resulting in more uniform heating, reduced heating time, and improved performance. Attached Figure Description

The inner cylinder 12 and the circular top cover 5 are movably connected by a pneumatic push rod 4. The pneumatic push rod 4 is fixedly installed on the outer surfaces of both sides of the inner cylinder 12. The outer cylinder 13 has a hollow internal structure, and two sets of condensate inlets 1 are fixedly installed on the lower outer surface of the outer cylinder 13.

[0035] Several sets of heat-conducting rings 10 are connected and fixed together by heat-conducting frames 29. The heat-conducting frames 29 are fixedly installed at the upper and lower ends of the heat-conducting rings 10. The heat-conducting rings 10 and the electric heating tubes 11 are connected by heat-conducting rods 30. When the polymerization reactor is in use, the heat generated by the electric heating tubes 11 during operation can be conducted to the heat-conducting rings 10 using the heat-conducting rods 30. The heat-conducting rings 10 adopt an overall ring structure design. The heat-conducting rings 10 are immersed in the material inside the inner cylinder 12. At the same time, the heat-conducting frames 29 are used to make multiple heat-conducting rings 10 heat up at the same time, making the heating operation of the polymerization reactor more uniform and shortening its heating time.

[0036] A telescopic tube 2 is provided at the lower middle part of the inner cylinder 12. The telescopic tube 2 has a plug inside. The upper outer surface of the telescopic tube 2 is provided with a feed nozzle 28, and the lower outer surface of the telescopic tube 2 is provided with a discharge pipe head 26. The upper end of the feed nozzle 28 is movably sleeved with a rotating bracket 27 for use with the stirring rod 3. The rotating bracket 27 provides support for the bottom of the stirring rod 3, reducing the friction when the stirring rod 3 rotates. Then, the user pulls down the telescopic tube 2 to open the discharge pipe head 26, allowing the material in the inner cylinder 12 to enter the telescopic tube 2 through the feed nozzle 28 and then be discharged through the discharge pipe head 26.

[0037] Mixing rods 23 are fixedly installed on both outer surfaces of the stirring rod 3, and a stirring frame 25 is fixedly installed on the lower outer surface of the stirring rod 3. The stirring frame 25 has a hollow structure inside. The stirring rod 3 synchronously drives the mixing rods 23 and the stirring frame 25 to rotate. The stirring frame 25 plays a mixing role on the material at the bottom of the inner cylinder 12. Secondly, the mixing rods 23 can be used to mix the material in the middle and upper parts of the inner cylinder 12. The hollow structure design of the stirring frame 25 can effectively reduce the resistance when the stirring frame 25 rotates.

[0038] The upper end of the stirring rod 3 is movably connected to the rotating shaft 24. The stirring rod 3 and the circular top cover 5 are movably connected through the rotating shaft 24. The upper end of the circular top cover 5 is provided with a motor 21 for driving the stirring rod 3. The outer side surface of the mixing rod 23 is provided with a sloping scraper groove 22. The user starts the motor 21, which drives the stirring rod 3 to rotate, so that the stirring rod 3 synchronously drives the mixing rod 23 and the stirring frame 25. When the mixing rod 23 rotates, the sloping scraper groove 22 can reduce the resistance when the mixing rod 23 rotates.

[0039] The upper end of the pneumatic push rod 4 is movably sleeved with a telescopic rod 20 for driving the circular top cover 5. The inner side of the pneumatic push rod 4 is equipped with a pressure valve. A fixing ring 19 for connecting to the upper end of the inner cylinder 12 is fixedly installed on one side of the pneumatic push rod 4. When the pressure inside the inner cylinder 12 is too high, the pressure valve inside the pneumatic push rod 4 is automatically opened, so that the pneumatic push rod 4 uses high-pressure gas to drive the telescopic rod 20, so that the telescopic rod 20 quickly moves the circular top cover 5 upward, thereby opening the circular top cover 5 at the upper part of the inner cylinder 12, quickly releasing the pressure inside the inner cylinder 12, and preventing the inner cylinder 12 from exploding.

[0040] The flow divider ring 9 has an overall annular hollow structure. A T-shaped tube 18 is fixedly installed on the inner side of the flow divider ring 9. A feed pipe 7 for use with the T-shaped tube 18 is fixedly installed on the upper end of the circular top cover 5. The user injects the material into the T-shaped tube 18 through the feed pipe 7 and pours the material into the flow divider ring 9 through the T-shaped tube 18. The flow divider ring 9 is used to divide the material, so that the material is evenly distributed into the inner cylinder 12, thereby improving the mixing effect.

[0041] A diversion pipe 15 is fixedly installed inside the diversion ring 9. The diversion pipe 15 has an overall ring structure. Several sets of spray heads 16 are fixedly installed at the lower part of the diversion pipe 15. A solenoid valve 17 is provided in the middle of the T-shaped pipe 18, and a main discharge port is provided at the lower middle of the T-shaped pipe 18. The opening or closing of the T-shaped pipe 18 can be controlled by the solenoid valve 17. When the solenoid valve 17 is open, the material in the T-shaped pipe 18 is discharged directly through the main discharge port. When the solenoid valve 17 is closed, the material in the T-shaped pipe 18 is discharged through the spray heads 16. The user can control the opening and closing of the solenoid valve 17 according to the material type.

[0042] A hand hole 6 is provided on the upper outer surface of the circular top cover 5, and a thermometer hole 8 is provided on the side of the upper outer surface of the circular top cover 5 near the hand hole 6.

[0043] A fixed bracket 14 is fixedly installed on the lower part of the outer surface of the outer cylinder 13. The lower middle part of the inner cylinder 12 and the outer cylinder 13 are provided with a circular groove for use with the telescopic pipe 2.

[0044] This chemical polymerization reactor with temperature control features multiple heating structures, including steam heating and electric heating, through the installation of an electric heating element 11 and a pneumatic pusher 4. The electric heating element allows for direct temperature regulation, enabling precise control of the polymerization reactor's heating temperature. During operation, the user directly introduces the chemical material into the inner cylinder 12 via the feed pipe 7. With a normal power supply, the electric heating element 11, in conjunction with the heat-conducting ring 10, heats the chemical material inside the inner cylinder 12. The user starts the motor 21, which drives the stirring rod 3 to rotate. The mixing rod 3 drives the mixing rod 23 and the mixing frame 25 to mix and stir the chemical materials in the inner cylinder 12. In addition, the use of two sets of pneumatic push rods 4 gives the inner cylinder 12 a rapid pressure relief structure. The two sets of pneumatic push rods 4 are connected to the side of the inner cylinder 12. When the pressure in the inner cylinder 12 is too high, the air pressure valve in the pneumatic push rod 4 will open automatically, so that the pneumatic push rod 4 uses high pressure gas to drive the telescopic rod 20. The telescopic rod 20 will quickly move the circular top cover 5 upward, so that the circular top cover 5 will open at the top of the inner cylinder 12, quickly releasing the pressure in the inner cylinder 12 and preventing the inner cylinder 12 from exploding. This effectively improves the safety of the polymerization reactor during use.

[0045] By configuring the outer cylinder 13 and the flow divider ring 9, when using this temperature-controlled polymerization reactor for chemical applications, the outer cylinder 13 allows for continuous heating of the inner cylinder 12 via steam heating even during power outages. This prevents blockages and build-up inside the inner cylinder 12 due to power failure. During operation, the user introduces high-temperature steam into the outer cylinder 13 through its inlet. The outer cylinder 13 completely encloses the outer surface of the inner cylinder 12, enabling steam heating. The condensate generated during heating is discharged directly through the condensate outlet 1. Furthermore, the flow divider ring 9 allows for the mixing of raw materials according to their type during introduction. The flow-diversion operation ensures thorough mixing of various raw materials. During operation, the user injects the material into the T-tube 18 through the feed pipe 7, and then pours the material into the flow-diversion ring 9 through the T-tube 18. The flow-diversion ring 9 diverts the material, ensuring that the material is evenly distributed into the inner cylinder 12, thus improving the mixing effect. The opening and closing of the T-tube 18 can be controlled by the solenoid valve 17. When the solenoid valve 17 is open, the material in the T-tube 18 is directly discharged through the main outlet. When the solenoid valve 17 is closed, the material in the T-tube 18 is discharged through the spray head 16. The user can control the opening and closing of the solenoid valve 17 according to the material type, thus ensuring that the polymerization reactor has an auxiliary flow-diversion structure, making the material mixing more thorough.

[0046] By setting up the stirring frame 25 and the heat-conducting ring 10, when using this temperature-controlled polymerization reactor for chemical applications, the user can utilize the stirring frame 25 and the stirring rod 3 to form a multi-mixing structure, ensuring thorough mixing of the bottom and top of the polymerization reactor. Secondly, the heat-conducting ring 10 ensures that the chemical materials inside the inner cylinder 12 are fully heated, shortening the heating time required for the polymerization reactor. During operation, the user starts the motor 21, which drives the stirring rod 3 to rotate, causing the stirring rod 3 to synchronously drive the mixing rod 23 and the stirring frame. 25. When the mixing rod 23 rotates, the inclined scraper groove 22 reduces the resistance of the mixing rod 23 during rotation. At the same time, the stirring frame 25 adopts a hollow structure design, which has low resistance. Secondly, the heat-conducting rod 30 can be used to conduct the heat generated by the electric heating tube 11 to the heat-conducting ring 10. The heat-conducting ring 10 adopts an overall ring structure design and is immersed in the material inside the inner cylinder 12. At the same time, the heat-conducting frame 29 enables multiple heat-conducting rings 10 to heat up simultaneously, making the heating operation of the polymerization reaction device more uniform, shortening its heating time, and improving its performance.
