Description

Technical Field

[0001] This invention relates to the field of polyethylene polyamine production technology, specifically to a reaction apparatus for the production of polyethylene polyamine. Background Technology

[0002] Polyethylene polyamines are a type of ethylenediamine, including linear homologues, branched-chain, or cyclic amines of ethylenediamine. Common linear polyethylene polyamines include diethylenetriamine, triethylenetetramine (linear chain), and tetraethylenepentamine (linear chain), which are widely used in papermaking, lubricant additives, chelating agents, and curing agents. In recent years, my country's ethylenediamine market has gradually become saturated, but the production capacity of linear polyethylene polyamines remains low, and high-quality products rely on imports, limiting the development of downstream industries. With the continuous maturation of the domestic chemical industry and the gradual optimization of its industrial structure, the market demand for high-purity linear polyethylene polyamine products is increasing daily.

[0003] During the mixing process, uneven stirring can easily lead to unstable product quality, resulting in problems such as stratification and clumping. Polyethylene polyamines have high viscosity and reactivity, requiring mixing equipment to fully and evenly mix all raw materials to ensure complete reaction and product consistency. The mixing time is long. Due to equipment design flaws and low stirring efficiency, traditional equipment often requires a long time to achieve the expected mixing effect, which leads to extended production cycles and affects overall production efficiency. The operation is also complex. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a reaction device for producing polyethylene polyamine, comprising a tank, three pillars fixedly connected to the bottom edge of the tank, the three pillars being evenly distributed at the bottom of the tank, a feed pipe fixedly connected to the middle of the bottom of the tank, and a heating pipe installed inside the tank.

[0005] The fastener is fixedly installed on the top of the tank. The top of the fastener is fixedly connected to the feed pipe. The middle of the top of the fastener is fixedly connected to the frame. The top of the frame is fixedly connected to the motor.

[0006] The connector is fixedly installed at the output end of the motor and is located inside the frame.

[0007] A stirring assembly is installed inside the tank.

[0008] The stirring assembly includes a rotating shaft, which is fixedly connected to a connecting piece. The rotating shaft is located inside the tank and extends through the fixing piece into the interior of the frame. Raw materials are added to the tank through a feed pipe. The motor is powered by an external power source and drives the rotating shaft to rotate, which in turn drives the fixed base and rotating plate to rotate. Simultaneously, the rotating shaft drives the L-shaped plate to rotate. Through the combined action of the rotating plate and the L-shaped plate, the raw materials inside the tank are stirred and mixed, ensuring that different reactants in the raw materials come into full contact and are evenly distributed, avoiding local concentrations that are too high or too low. This ensures that the reaction proceeds evenly in all parts, thereby improving the quality and stability of the product. It also enables uniform mixing and reaction of materials in a shorter time, reducing stirring time and energy consumption. A fixed ring is fixedly connected to the bottom of the rotating shaft, and a groove is opened on the outer side of the fixed ring. An L-shaped plate is slidably connected inside the groove. A fixed base is fixedly connected to the outer side of the rotating shaft, and an inclined plate is fixedly connected to the side of the L-shaped plate closest to the fixed base. A rotating plate is fixedly connected to the outer side of the fixed base.

[0009] Preferably, there are two chutes, symmetrically arranged around the rotating shaft. The side of the L-shaped plate away from the fixed ring contacts the inside of the tank. A circular groove is opened at the end of the L-shaped plate away from the fixed ring. The motor is powered by an external power source and drives the rotating shaft to rotate. The rotating shaft drives the L-shaped plate to rotate. Utilizing the interaction between the circular groove and the spiral convex ring, as the rotating shaft rotates, the L-shaped plate moves up and down along the spiral convex ring inside the chutes. Thus, the L-shaped plate drives the inclined plate to move up and down. Under the push of the inclined plate, the raw material at the edge of the tank moves towards the center. The rotating plate rotates, pushing the raw material in the center outward. At this time, the raw material inside the tank forms a cyclical backflow from the outside to the inside and back to the outside, ensuring sufficient contact and mixing between the raw materials and improving reaction efficiency. The circular grooves are evenly arranged on the side of the L-shaped plate. There are two fixed seats, which are alternately arranged with the inclined plate.

[0010] Preferably, the tank body includes an outer shell, an inner tank body is provided inside the outer shell, a spiral convex ring is fixedly connected to the inner wall of the inner tank body, a heating tube is located inside the spiral convex ring and inside the gap between the outer shell and the inner tank body, an extension tube is fixedly connected to the middle of the bottom of the inner tank body, the extension tube is fixedly connected to the discharge tube, and the spiral convex ring is located inside the circular groove.

[0011] Preferably, the fixing component includes a top cover, which is fixedly connected to the top of the outer shell. A sealing ring is fixedly connected to the middle of the top of the top cover, and the sealing ring is sleeved on the outside of the rotating shaft. An exhaust pipe is fixedly connected to the top of the top cover, and the exhaust pipe is located on the side away from the feed pipe. A sliding cylinder is slidably connected to the outside of the exhaust pipe. A fixing rod is fixedly connected inside the exhaust pipe, and a circular plate made of rubber is provided on the outside of the fixing rod. During the exhaust process, the circular plate deforms under the action of the air pressure inside the tank. The circular plate is in close contact with the outside of the U-shaped cylinder to prevent excessive deformation of the circular plate. Since foam may be generated during the reaction stirring process, These foams may carry the reaction liquid out of the vent pipe. By using a circular plate, the deformed plate acts as a barrier, blocking the foam and liquid as they pass through and causing them to flow back into the tank. The center of the circular plate is fixedly connected to the center of the fixing rod. A spiral groove is formed inside the vent pipe, and a limit ring is fixedly connected to the inner wall of the vent pipe. The limit ring is a T-shaped ring. A U-shaped cylinder is located on the side of the vent pipe near the limit ring. A cylinder is fixedly connected to the inner wall of the opening of the U-shaped cylinder. The end of the cylinder away from the U-shaped cylinder is fixedly connected to the limit ring. A sphere is slidably connected inside the U-shaped cylinder. During the reaction in the tank... Under high temperature and pressure, when the internal pressure of the tank is too high, the circular plate deforms under stress. The circular plate makes close contact with the outer side of the U-shaped cylinder to prevent excessive deformation. At this time, the high-pressure gas inside the tank enters the interior of the outlet pipe through the gap between the outlet pipe and the circular plate. The high-pressure gas flows along the spiral grooves on the inner wall of the outlet pipe. By setting the spiral grooves, the flow path of the high-pressure gas is lengthened, thereby reducing sudden changes in flow velocity and reducing noise caused by fluctuations in gas flow velocity. The high-pressure gas enters the interior of the U-shaped cylinder through the limiting ring, exerting a force on the sphere, causing the sphere to move towards the bottom of the U-shaped cylinder. The ball drives the sliding cylinder to slide on the exhaust pipe, causing the through hole on the sliding cylinder to overlap with the connecting hole on the exhaust pipe. At this time, the high-pressure gas passes through the gap between the ball and the limiting ring, and then is discharged from the connecting hole and the through hole. When the internal gas pressure returns to the normal range, the ball and the sliding cylinder are reset under the elastic force of the spring plate, and the exhaust stops. A round rod is fixedly connected to the side of the ball near the sliding cylinder. The round rod is fixedly connected to the middle of the inside of the sliding cylinder. A spring plate is fixedly connected to the outside of the round rod. The end of the spring plate away from the round rod is fixedly connected to the limiting ring. A through hole is opened on the outside of the sliding cylinder, and a connecting hole is opened on the outside of the exhaust pipe near the sliding cylinder.

[0012] Preferably, the connector includes a fixing block, which is fixedly connected to the top of the rotating shaft. A gasket is fixedly installed on the side of the fixing block away from the rotating shaft. The gasket is elastic. A middle block is fixedly installed on the outer side of the gasket. The gaskets are symmetrically arranged around the middle block. A protrusion is fixedly connected to the middle of the fixing block. The protrusion and the middle block are corrugated and fitted together. A contact rod is fixedly connected to the outer edge of the fixing block. A limit rod is provided on the top of the contact rod. The contact surface between the limit rod and the contact rod is inclined. During the stirring process, the load on the rotating shaft may fluctuate due to factors such as the unevenness of the material and changes in the stirring speed. By setting the gasket, the elastic properties of the gasket can effectively buffer these impacts and prevent them from being directly transmitted to the motor and other drive equipment. At the same time, when vibrating, a relative displacement occurs between the contact rod and the limit rod. The inclined contact prevents the connector from slipping. A positioning block is fixedly connected to the end of the limit rod away from the contact rod. The positioning block is fixedly connected to the output end of the motor.

[0013] This invention provides a reaction apparatus for the production of polyethylene polyamines. It has the following beneficial effects:

[0014] I. The reaction apparatus for producing polyethylene polyamine uses a rotating plate and an L-shaped plate to stir and mix the raw materials inside the tank. This ensures that the different reactants in the raw materials come into full contact and are evenly distributed, avoiding situations where the concentration is too high or too low in certain areas. This ensures that the reaction can proceed evenly in all parts, thereby improving the quality and stability of the product.

[0015] II. In this reaction apparatus for producing polyethylene polyamine, the raw material at the edge of the tank moves towards the center under the push of the inclined plate. The rotating plate pushes the raw material in the center outward. At this time, the raw material inside the tank forms a cyclic reflux from the outside to the inside and back to the outside, ensuring full contact and mixing between the raw materials and improving the reaction efficiency.

[0016] Third, the reaction device for producing polyethylene polyamines, by setting up a spiral groove, makes the flow path of high-pressure gas longer, thereby reducing sudden changes in flow velocity and thus reducing the noise caused by fluctuations in gas flow velocity.

[0017] IV. The reaction device for producing polyethylene polyamine can effectively buffer these impacts by setting gaskets and utilizing the elastic properties of the gaskets, preventing them from being directly transmitted to the drive equipment such as motors. At the same time, during vibration, relative displacement occurs between the contact rod and the limiting rod, and the inclined contact is used to avoid slippage of the connecting parts.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0029] First embodiment, such as Figures 1 to 5As shown, the present invention provides a technical solution: a reaction device for producing polyethylene polyamine, including a tank 1, a support column 2 fixedly connected to the bottom edge of the tank 1, the number of support columns 2 is three, the three support columns 2 are evenly distributed at the bottom of the tank 1, a feed pipe 6 is fixedly connected to the middle of the bottom of the tank 1, and a heating pipe 5 is provided inside the tank 1.

[0030] Fixing component 3 is fixedly installed on the top of tank body 1. A feed pipe 9 is fixedly connected to the top of fixing component 3. A frame 10 is fixedly connected to the middle of the top of fixing component 3. A motor 4 is fixedly connected to the top of frame 10.

[0031] Connector 8 is fixedly installed at the output end of motor 4 and is located inside frame 10.

[0032] Stirring component 7 is installed inside tank 1;

[0033] The stirring assembly 7 includes a rotating shaft 71, which is fixedly connected to the connecting member 8. The rotating shaft 71 is located inside the tank body 1 and extends through the fixing member 3 into the interior of the frame 10. Raw materials are added into the tank body 1 through the feed pipe 9. The motor 4 is powered by an external power source and drives the rotating shaft 71 to rotate, which in turn drives the fixing base 76 and the rotating plate 77 to rotate. At the same time, the rotating shaft 71 drives the L-shaped plate 74 to rotate. Through the joint operation of the rotating plate 77 and the L-shaped plate 74, the raw materials inside the tank body 1 are stirred and mixed, thereby enabling different reactants in the raw materials to fully contact and be evenly distributed. To avoid situations where the local concentration is too high or too low, and to ensure that the reaction can proceed uniformly in all parts, thereby improving the quality and stability of the product, it can also achieve uniform mixing and reaction of materials in a shorter time, reducing stirring time and energy consumption. A fixing ring 72 is fixedly connected to the bottom of the rotating shaft 71, and a sliding groove 73 is opened on the outer side of the fixing ring 72. An L-shaped plate 74 is slidably connected inside the sliding groove 73. A fixing seat 76 is fixedly connected to the outer side of the rotating shaft 71. An inclined plate 78 is fixedly connected to the side of the L-shaped plate 74 near the fixing seat 76. A rotating plate 77 is fixedly connected to the outer side of the fixing seat 76.

[0034] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 4 to 5As shown, there are two swivels 73, symmetrically arranged around the rotating shaft 71. The side of the L-shaped plate 74 away from the fixing ring 72 contacts the interior of the tank body 1. A circular groove 75 is formed at the end of the L-shaped plate 74 away from the fixing ring 72. The motor 4 is powered by an external power source and drives the rotating shaft 71 to rotate. The rotating shaft 71 drives the L-shaped plate 74 to rotate. Utilizing the interaction between the circular groove 75 and the spiral convex ring 13, as the rotating shaft 71 rotates, the L-shaped plate 74 moves along the spiral convex ring 13 in the swivel 73. The internal reciprocating motion causes the L-shaped plate 74 to drive the inclined plate 78 to move up and down. Under the push of the inclined plate 78, the raw material at the edge of the tank 1 moves towards the center. The rotating plate 77 rotates, pushing the raw material in the center outward. At this time, the raw material inside the tank 1 forms a circular reflux from the outside to the inside and back to the outside, ensuring full contact and mixing between the raw materials and improving the reaction efficiency. The circular grooves 75 are evenly arranged on the side of the L-shaped plate 74. There are two fixed seats 76, which are alternately set with the inclined plate 78.

[0035] The tank 1 includes an outer shell 11, and an inner tank 12 is provided inside the outer shell 11. A spiral protrusion ring 13 is fixedly connected to the inner wall of the inner tank 12. The heating tube 5 is located inside the spiral protrusion ring 13 and is located inside the gap between the outer shell 11 and the inner tank 12. An extension tube 14 is fixedly connected to the middle of the bottom of the inner tank 12. The extension tube 14 is fixedly connected to the discharge tube 6. The spiral protrusion ring 13 is located inside the circular groove 75.

[0036] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 6 to 7As shown, the fixing component 3 includes a top cover 31, which is fixedly connected to the top of the outer shell 11. A sealing ring 32 is fixedly connected to the middle of the top of the top of the top cover 31. The sealing ring 32 is sleeved on the outside of the rotating shaft 71. An exhaust pipe 33 is fixedly connected to the top of the top cover 31. The exhaust pipe 33 is located on the side away from the feed pipe 9. A sliding cylinder 34 is slidably connected to the outside of the exhaust pipe 33. A fixing rod 311 is fixedly connected inside the exhaust pipe 33. A circular plate 312 is provided on the outside of the fixing rod 311. The circular plate 312 is made of rubber. During the exhaust process, the circular plate 312 deforms under the action of the air pressure inside the tank. The circular plate 312 is in close contact with the outside of the U-shaped cylinder 36 to prevent excessive deformation of the circular plate 312. Due to the possibility of reaction stirring during the process... Foam is generated, and this foam may carry the reaction liquid out of the vent pipe 33. A circular plate 312 is provided; the deformed plate 312 acts as a barrier, blocking the foam and liquid when they come into contact with it and causing them to flow back into the tank 1. The middle of the circular plate 312 is fixedly connected to the middle of the fixing rod 311. A spiral groove 35 is provided inside the vent pipe 33. A limiting ring 38 is fixedly connected to the inner wall of the vent pipe 33. The limiting ring 38 is a T-shaped ring. A U-shaped cylinder 36 is provided on the side of the vent pipe 33 near the limiting ring 38. A cylinder 37 is fixedly connected to the inner wall of the opening of the U-shaped cylinder 36. The end of the cylinder 37 away from the U-shaped cylinder 36 is fixedly connected to the limiting ring 38. A sphere 39 is slidably connected inside the U-shaped cylinder 36. During the reaction process of tank 1, the tank is under high temperature and high pressure. When the internal gas pressure of tank 1 is too high, the circular plate 312 deforms under stress. The circular plate 312 is in close contact with the outer side of the U-shaped cylinder 36 to prevent excessive deformation of the circular plate 312. At this time, the high-pressure gas inside tank 1 enters the interior of the outlet pipe 33 along the gap between the outlet pipe 33 and the circular plate 312. The high-pressure gas flows along the spiral groove 35 on the inner wall of the outlet pipe 33. By setting the spiral groove 35, the flow path of the high-pressure gas is lengthened, thereby reducing sudden changes in flow velocity and reducing the noise caused by fluctuations in gas flow velocity. The high-pressure gas enters the interior of the U-shaped cylinder 36 along the limiting ring 38, exerting a force on the sphere 39, causing the sphere 39 to move towards the bottom of the U-shaped cylinder 36. The ball 39 drives the sliding cylinder 34 to slide on the exhaust pipe 33, causing the through hole 314 on the sliding cylinder 34 to overlap with the connecting hole 315 on the exhaust pipe 33. At this time, high-pressure gas passes through the gap between the ball 39 and the limiting ring 38, and then exits from the connecting hole 315 and the through hole 314. When the internal air pressure returns to the normal range, the ball 39 and the sliding cylinder 34 return to their original positions under the elastic force of the spring plate 310, stopping the exhaust. A round rod 313 is fixedly connected to the side of the ball 39 near the sliding cylinder 34. The round rod 313 is fixedly connected to the middle of the interior of the sliding cylinder 34. A spring plate 310 is fixedly connected to the outside of the round rod 313. The end of the spring plate 310 away from the round rod 313 is fixedly connected to the limiting ring 38. The sliding cylinder 34 has a through hole 314 on its outer side.A connecting hole 315 is provided on the outer side of the air outlet pipe 33 near the sliding cylinder 34.

[0037] For the fourth embodiment, please refer to [link / reference]. Figures 8 to 9 As shown, the connector 8 includes a fixing block 81, which is fixedly connected to the top of the rotating shaft 71. A gasket 82 is fixedly installed on the side of the fixing block 81 away from the rotating shaft 71. The gasket 82 is elastic. A middle block 83 is fixedly installed on the outer side of the gasket 82. The gaskets 82 are symmetrically arranged with the middle block 83 as the center. A protrusion 87 is fixedly connected to the middle of the fixing block 81. The protrusion 87 and the middle block 83 are adapted to each other. A contact rod 85 is fixedly connected to the outer edge of the fixing block 81. A limit rod 86 is provided on the top of the contact rod 85. The contact rod 86 and the contact rod 85 are in contact. Since the surface is inclined, the load on the rotating shaft 71 may fluctuate during the stirring process due to factors such as the unevenness of the material and changes in the stirring speed. By setting a shim 82, the elastic properties of the shim 82 can effectively buffer these impacts and prevent them from being directly transmitted to the driving equipment such as the motor 4. At the same time, when vibrating, a relative displacement occurs between the contact rod 85 and the limit rod 86. The inclined surface contact is used to prevent the connecting part 8 from slipping. The end of the limit rod 86 away from the contact rod 85 is fixedly connected to the positioning block 84, and the positioning block 84 is fixedly connected to the output end of the motor 4.

[0038] In use, the raw materials are added into the tank 1 through the feed pipe 9. The motor 4 is powered by an external power source and drives the rotating shaft 71 to rotate. This causes the rotating shaft 71 to rotate the fixed base 76 and the rotating plate 77. At the same time, the rotating shaft 71 drives the L-shaped plate 74 to rotate. Utilizing the cooperation between the circular groove 75 and the spiral convex ring 13, as the rotating shaft 71 rotates, the L-shaped plate 74 moves up and down along the spiral convex ring 13 inside the sliding groove 73. As a result, the L-shaped plate 74 drives the inclined plate 78 to move up and down. Under the push of the inclined plate 78, the raw materials at the edge of the tank 1 move towards the center. The rotating plate 77 rotates, pushing the raw materials in the center outward. At this time, the raw materials inside the tank 1 form a circular backflow from the outside to the inside and back to the outside. Through the joint work of the rotating plate 77 and the L-shaped plate 74, the raw materials inside the tank 1 are stirred and mixed.

[0039] During the reaction process, tank 1 is under high temperature and high pressure. When the internal pressure of tank 1 becomes too high, the circular plate 312 deforms under stress. The circular plate 312 is in close contact with the outer side of the U-shaped cylinder 36 to prevent excessive deformation of the circular plate 312. At this time, the high-pressure gas inside tank 1 enters the interior of the outlet pipe 33 along the gap between the outlet pipe 33 and the circular plate 312. The high-pressure gas flows along the spiral groove 35 on the inner wall of the outlet pipe 33. By setting the spiral groove 35, the flow path of the high-pressure gas is lengthened, thereby reducing sudden changes in flow velocity and reducing the noise caused by fluctuations in gas flow velocity. High-pressure gas enters the interior of the U-shaped cylinder 36 along the limiting ring 38, exerting a force on the sphere 39, causing the sphere 39 to move towards the bottom of the U-shaped cylinder 36. As a result, the sphere 39 drives the sliding cylinder 34 to slide on the exhaust pipe 33, causing the through hole 314 on the sliding cylinder 34 to overlap with the connecting hole 315 on the exhaust pipe 33. At this time, the high-pressure gas passes through the gap between the sphere 39 and the limiting ring 38, and then exits from the connecting hole 315 and the through hole 314. When the internal gas pressure returns to the normal range, under the elastic force of the spring plate 310, the sphere 39 and the sliding cylinder 34 reset, and the exhaust stops.
