Description

Technical Field

[0001] This invention relates to the field of reaction vessel technology, specifically to a polymerization reaction vessel for producing coated asphalt. Background Technology

[0002] A reaction vessel is a closed pressure vessel used to realize physical or chemical reactions. By precisely controlling parameters such as temperature, pressure, and stirring rate, it provides a controllable reaction environment for materials. Its core functions include heating, cooling, evaporation, mixing, and promoting chemical reactions. It is a core piece of equipment in industries such as petroleum, chemical, pharmaceutical, and food.

[0003] Existing technologies also have the following problems: Most existing reactors use a single rotating stirring rod, resulting in a fixed stirring trajectory and limited stirring range, making it difficult to act on the corners and bottom of the tank; due to the high viscosity of asphalt, it easily forms agglomerated particles with modifiers, and a single stirring mode cannot generate sufficient shear force to break up the agglomerated structure, leading to uneven distribution of the modifier in the asphalt; furthermore, existing reactors are mostly vertical cylindrical structures, where materials tend to accumulate to the bottom under gravity, and the high viscosity of asphalt further exacerbates the deposition phenomenon; the stirring rods of traditional stirring mechanisms are mostly concentrated in the upper part of the tank, making it difficult to effectively stir the materials deposited at the bottom, resulting in the bottom material remaining in a "static or weakly dynamic" state for a long time, with the reaction progress not synchronized with the upper material, leading to problems of local over-reaction and local unreaction.

[0004] To address this, a polymerization reactor for coated asphalt production is proposed. Summary of the Invention

[0011] Preferably, an electrical connection is established between the driver and the power supply, and one end of the guide plate that is fixedly connected to the collar is a fixed endpoint.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The combined effect of high-pressure gas injection from the nozzles into the material at the bottom of the tank and the outward expansion and compression of the material by the second rubber annular cylinder pushes the material at the bottom of the tank upward. Combined with the feed inlets of the annular array on the outer wall of the first rubber annular cylinder, material from different areas inside the tank can be evenly introduced into the first rubber annular cylinder, achieving a circular transport of material from the bottom to the top of the tank. Furthermore, when the collar slides along the first connecting rod, it drives the guide plate to push the annular rod, causing the nozzle linked to the limiting block to spray into different areas at the bottom of the tank. Simultaneously, the first and second connecting rods work together to expand the first and second rubber annular cylinders, further increasing the material circulation range and avoiding the material sedimentation problem at the bottom of traditional reactors.

[0020] 2. In the preliminary processing mechanism, the collar drives the guide plate, which is tilted at 30 degrees, to rotate. The baffles on the outer wall of the scraper, which are perpendicular to each other, shear and divert the material, breaking up asphalt agglomerates. Combined with the rotating stirring rods in the annular array at the bottom of the connecting rod, the mixing uniformity of the modifier and the base asphalt is greatly improved. In addition, when the collar drives the guide plate to move downward, the annular rod pushes the connecting rod one and the connecting rod two, causing the rubber annular cylinder two to contract, reducing the material movement space and increasing the material collision frequency. At the same time, the connecting rod one drives the stirring rod to stir the material in the rubber annular cylinder one and the rubber annular cylinder two, accelerating the reaction process and shortening the reaction completion time.

Detailed implementation mode

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0037] Please see Figures 1 to 13 An embodiment of the present invention provides a polymerization reactor for producing coated asphalt, comprising a tank body 101, a top cover 102, a driver 103, and a power supply 104. The top cover 102 is fixedly connected to the top of the tank body 101, the driver 103 is fixedly connected to the top of the top cover 102, and the power supply 104 is fixedly connected to the top of the driver 103. An electrical connection is established between the driver 103 and the power supply 104. A partial preliminary processing mechanism 200 is provided in the inner cavity of the tank body 101, and a partial circulating processing mechanism 300 is provided in the inner cavity of the tank body 101.

[0038] The preliminary processing mechanism 200 includes a second linkage rod 202-1, a stirring rod 203, a collar 204, a guide plate 205, and a scraper 206. The second linkage rod 202-1 is slidably disposed inside the tank body 101. The stirring rod 203 is arranged in a ring array and fixedly connected to the outer wall of the second linkage rod 202-1. The collar 204 is slidably disposed on the top of the second linkage rod 202-1. The guide plate 205 is arranged in a ring array and fixedly connected to the outer wall of the collar 204. One end of the guide plate 205 that is fixedly connected to the collar 204 is a fixed endpoint. The guide plate 205 moves towards the opposite direction based on this fixed endpoint. The outer side of the collar 204 is inclined upward at a 30-degree angle. The scraper 206 is slidably connected to the inner wall of the guide plate 205 away from the collar 204. The size of the scraper 206 away from the collar 204 is adapted to the size of the inner wall of the tank 101, and the scraper 206 is always in contact with the inner wall of the tank 101. The guide plate 205 and the scraper 206 correspond one-to-one. The scraper 206 set inside the preliminary processing mechanism 200 can scrape off the material adhering to the inner wall of the tank 101, so that the adhering material falls back into the reaction system and is repeatedly stirred under the action of the stirring rod 203 to avoid material residue from stirring.

[0039] The circulating processing mechanism 300 includes a guide groove 302, annular rods 304, connecting rod one 309, connecting rod two 310, rubber ring plate one 311, rubber annular cylinder one 312, and rubber annular cylinder two 315. The guide groove 302 is formed through the side wall of the guide plate 205. The annular rods 304 are symmetrically arranged inside the tank body 101. The connecting rod one 309 is arranged between the two annular rods 304. The size of the annular rods 304 is adapted to the size of the guide groove 302. The connecting rod two 310 is set... At the bottom of the inner cavity of the tank 101, rubber ring plates 311 are symmetrically fixed to the inner wall of connecting rod 309, rubber annular cylinder 312 is fixedly connected between the two rubber ring plates 311, and rubber annular cylinder 315 is fixedly connected to the inner wall of connecting rod 310. Through the repeated expansion and contraction of rubber annular cylinder 312 and rubber annular cylinder 315 inside the circulation processing mechanism 300, large volume materials are divided into small volume materials for gradual circulation and stirring, which can improve the stirring effect.

[0040] It should be noted that a conductive element is provided between the power supply 104 and the internal drive device of the driver 103, so that the power supply 104 can provide power to the driver 103 through the conductive element, and the operator can send commands to the drive panel inside the driver 103 through an external controller, so that the drive end of the driver 103 can extend or rotate.

[0041] Furthermore, the preliminary processing mechanism 200 also includes a feeding port 201 fixedly connected to the top of the top cover 102. The driving end of the driver 103 is fixedly connected to a first connecting rod 202. The top of the second connecting rod 202-1 slides on the inner wall of the bottom end of the first connecting rod 202. A collar 204 is fixedly connected to the outer wall of the bottom end of the first connecting rod 202. The collar 204 slides on the outer wall of the second connecting rod 202-1. A slider is provided on the inner wall of the collar 204, and the slider slides... In the groove opened on the outer wall of the linkage 202-1, four baffles 207 are fixedly connected in a linear array on the outer wall of the scraper 206. Each baffle 207 is formed by connecting two mutually perpendicular plates. A telescopic plate 208 is symmetrically fixedly connected on the outer wall of the scraper 206. A spring is provided between the fixed end and the telescopic end of the telescopic plate 208, which enables the telescopic plate 208 to automatically extend after compression. A limit plate 209 is fixedly connected to the bottom end of the scraper 206.

[0042] It should be noted that the side of the scraper 206 away from the collar 204 is in contact with the inner wall of the tank body 101, and the height of the scraper 206 is consistent with the height of the inner wall of the collar 204.

[0043] The collar 204 can only slide up and down on the outer wall of the connecting rod 202, and the collar 204 can rotate synchronously during the rotation of the connecting rod 202.

[0044] The core function of the scraper 206's fit to the inner wall of the tank 101 is to solve the problem of material adhering to the wall in asphalt production. Asphalt is prone to adhering to the reactor wall due to its high viscosity. Long-term accumulation can lead to local overheating and carbonization, affecting product purity and equipment heat transfer efficiency. When the scraper 206 moves with the guide plate 205, it can scrape off the material adhering to the tank wall in real time and bring it back to the reaction system, which can improve the utilization rate of raw materials and avoid scale buildup on the reactor wall.

[0045] The end of the baffle 207 near the inner wall of the tank 101 is adapted to the size of the inner wall of the tank 101, so that the baffle 207 can fit tightly against the inner wall of the tank 101 without hindering the scraper 206 from fitting tightly against the inner wall of the tank 101. The baffle 207 adopts a structure design of two mutually perpendicular plates, which is not simply used to block materials, but to form a grid-like interception space through the vertical plates, which forms a shearing and diversion effect on the materials during the mixing process: the longitudinal plate can break the circular flow trend of the materials, and the transverse plate can divide large clumps of asphalt raw materials into small particles. Combined with the rotational movement of the stirring rod 203, the uniformity of material mixing is further improved, which is especially suitable for the need for precise mixing of modifiers and base asphalt in the production of coated asphalt.

[0046] Furthermore, the circulating processing mechanism 300 also includes a discharge pipe 301 fixedly connected to the bottom end of the tank 101. A limiting groove 303 is formed through the interior of the limiting plate 209. The guide groove 302 has the same size as the limiting groove 303. The limiting groove 303 is formed through the interior of the limiting plate 209. Two annular rods 304 are slidably connected to the interior of the guide groove 302 and the limiting groove 303, respectively. Four sets of eight limiting blocks 305 are fixedly connected in a ring array on the outer wall of each of the two annular rods 304. Four sets of eight elastic blocks 306 are fixedly connected in a ring array on the outer wall of each of the two annular rods 304. A slot 307 is formed on the outer wall of the top of the guide plate 205. The limiting plate 205... A nozzle 308 is slidably connected to the outer wall of tank 101, and the nozzle 308 is fixedly connected to the limiting block 305. A connecting rod 1 309 is fixedly connected to the outer wall of the limiting block 305 at the top of the inner cavity of tank 101. The bottom end of the connecting rod 1 309 is fixedly connected to the top end of the connecting rod 2 310. The connecting rod 2 310, the connecting rod 1 309 and the scraper 206 correspond one-to-one. The connecting rod 2 310 is fixedly connected to the outer wall of the limiting block 305 at the bottom of the inner cavity of tank 101. An arc-shaped extrusion plate 310-1 is fixedly connected to the outer wall of the connecting rod 2 310. Several feed inlets 313 are arranged in a ring array on the outer wall of the rubber annular cylinder 1 312. The top end of the connecting rod 2 310 is fixedly connected to the outer wall of the connecting rod 2 310. A rubber ring plate 314 is fixedly connected to the bottom of a rubber annular cylinder 312. A rubber ring plate 311 is attached to the inner wall of the rubber ring plate 314, and the bottom of the rubber ring plate 314 is fixedly connected to the top of the rubber annular cylinder 315. All four components—rubber ring plate 311, rubber ring plate 314, rubber annular cylinder 315, and rubber annular cylinder 312—are made of high-heat-resistant modified fluororubber. The interior of the rubber ring plate 314 has four sets of eight mounting slots 316 arranged in a ring array. The top of the connecting rod 310 is fixedly connected to the mounting slot 316. The interior of the rubber ring plate 314 also has four sets of eight mounting slots 317 arranged in a ring array. 316 is internally connected to the mounting groove 317. A gas supply valve 318 is fixedly connected through the bottom of the tank 101. The gas supply valve 318 is connected to an external gas supply device. A circular cavity plate 319 is fixedly connected to the inner wall of the middle part of the tank 101. A gas guide telescopic rod 320 is fixedly connected to the bottom outer wall of the linkage rod 202-1. A connecting pipe 321 is fixedly connected to the end of the gas guide telescopic rod 320 away from the linkage rod 202-1. The connecting pipe 321 is fixedly connected to the inner wall of the nozzle 308. A gas guide pipe 322 is fixedly connected between two adjacent nozzles 308. The elastic block 306 and the gas guide pipe 322 are both made of synthetic rubber. A rubber tube 323 is fixedly connected to the middle part of the gas guide pipe 322.

[0047] It should be noted that the bottom drive of the rubber annular cylinder 315 is connected to the bottom of the inner cavity of the tank 101;

[0048] High heat-resistant modified fluororubber can achieve long-term high temperature resistance and maintain good elasticity and sealing performance even at high temperatures;

[0049] Several feed inlets 313 are provided along the length of the rubber annular cylinder 312, and the several feed inlets 313 are arranged in a circular array along the circumference of the rubber annular cylinder 312.

[0050] The rubber annular cylinder 312 is made of high heat-resistant modified fluororubber and has an inlet 313. It has both elastic sealing and material guiding functions: on the one hand, the elasticity of the high heat-resistant modified fluororubber allows the rubber annular cylinder 312 to fit tightly against the inner wall of the rubber ring plate 314, preventing material leakage from gaps during circulation, which is especially suitable for the high viscosity and easy leakage characteristics of asphalt; on the other hand, the inlet 313 of the annular array can evenly introduce materials from different areas of the tank into the rubber annular cylinder 312. With the pressurized spray of the nozzle 308, the material is circulated from the bottom to the top of the tank 101, breaking the limitations of traditional reactors where materials tend to settle at the bottom and are not sufficiently stirred at the top. This ensures that all materials in the tank are in the same reaction environment, improving the consistency of key indicators such as the residual carbon rate and softening point of the coated asphalt.

[0051] Working principle: In the initial state, the elastic block 306 is in an unstretched state, and the rubber ring plate 311, the rubber ring cylinder 312, the rubber ring plate 314, and the rubber ring cylinder 315 are all in an unstretched state.

[0052] During operation, the operator first feeds material into the tank 101 through the feeding port 201. Then, the operator supplies current to the driver 103 via the power supply 104, causing the driver 103 to drive the first connecting rod 202 to rotate inside the tank 101. This causes the first connecting rod 202 to synchronously rotate the collar 204. The collar 204 then abuts against the groove on the outer wall of the second connecting rod 202-1 via a slider, causing the collar 204 to synchronously rotate the second connecting rod 202-1. On the inner wall of the bottom end of the tank 101, the collar 204 drives the guide plate 205, which is fixedly connected to it, to rotate synchronously. The guide plate 205 abuts against the scraper 206 through the slot 307 and rotates synchronously. The scraper 206 drives the baffle 207, the telescopic plate 208, and the limiting plate 209 to rotate synchronously. The scraper 206 scrapes off the material adhering to the inside of the tank 101, and the material falls back into the reaction system under the stirring action of the baffle 207. Then, the material is further processed by the telescopic plate 208 and the limiting plate 209. Initial stirring is performed to achieve preliminary mixing of the materials. Simultaneously, the operator connects the gas supply valve 318 to an external gas supply device, causing the external gas supply device to inject high-pressure gas into the gas supply valve 318. The high-pressure gas then enters the connecting rod 202-1 through the circular cavity plate 319, then enters the gas guide telescopic rod 320 through the connecting rod 202-1, and finally enters the nozzle 308 through the gas guide telescopic rod 320. This causes the nozzle 308 to vertically spray high-pressure gas upwards from the bottom of the tank 101, pushing the material at the top of the nozzle 308 upwards. As the nozzle 308 expands outwards within the limiting groove 303, it can spray high-pressure gas into different areas of the material between the rubber annular cylinder 315 and the tank 101, thereby causing the material at the bottom of the rubber annular cylinder 315 and the tank 101 to gradually move upwards, realizing the cyclical transport of the material from the bottom to the top of the rubber annular cylinder 315 and the tank 101.

[0053] The combined action of high-pressure gas injection from nozzle 308 into the material at the bottom of tank 101 and the outward expansion and compression of the material by rubber annular cylinder 315 pushes the material at the bottom of tank 101 upward. This, combined with the feed inlets 313 of the annular array on the outer wall of rubber annular cylinder 312, allows for the uniform introduction of material from different areas of the tank into the rubber annular cylinder 312, achieving a circular transport of material from the bottom to the top of tank 101. Furthermore, when the collar 204 slides along the connecting rod 202, it drives the guide plate 205 to push the annular rod 304, causing the nozzle 308, linked to the limiting block 305, to spray into different areas of the bottom of tank 101. Simultaneously, the connecting rod 309 and connecting rod 310 work together to expand rubber annular cylinders 312 and 315, further increasing the material circulation range and avoiding the material deposition problem at the bottom of traditional reactors.

[0054] After the material is initially mixed, the operator sends a command to the drive panel inside the driver 103 via an external controller, causing the drive end of the driver 103 to extend and retract vertically in a single motion. During the extension of the drive end of the driver 103, the drive end of the driver 103 causes the bottom end of the first connecting rod 202 to slide downward on the outer wall of the second connecting rod 202-1, causing the first connecting rod 202 to simultaneously slide downward on the collar 204, causing the collar 204 to move the guide plate 205 downward, causing the guide plate 205 to simultaneously move the slot 307 downward on the outer wall of the scraper 206, causing the guide plate 205 to simultaneously move the guide groove 302 downward, causing the guide groove 302 to abut against the annular rod 304, causing the annular rod 304 to stop at the limit block. Under the limiting action of 305, the ring rod 304 moves horizontally from the bottom to the top of the guide groove 302, and during the movement, the ring rod 304 stretches the elastic block 306. At the same time, the ring rod 304 drives the connecting rod 1 309 to move synchronously away from the outer connecting rod 202 through the limiting block 305. This causes the connecting rod 1 309 to drive the connecting rod 2 310 to expand outward synchronously. This causes the connecting rod 2 310 to drive the limiting block 305 connected at the bottom to move synchronously. This causes the limiting block 305 to drive the ring rod 304, which is slidably connected inside the limiting groove 303, to move synchronously. This causes the ring rod 304 to drive the nozzle 308 to move synchronously away from the rubber annular cylinder 2 315, thereby realizing high-pressure spraying of different areas at the bottom of the tank 101 by the nozzle 308.

[0055] During the outward expansion of connecting rod 309, connecting rod 309 drives rubber ring plate 314 and connecting rod 310 to expand outward simultaneously, causing rubber ring plate 311 to expand simultaneously, and rubber ring cylinder 312 to expand simultaneously. During the expansion of rubber ring cylinder 312, the feed inlet 313 is gradually stretched and expanded. During the expansion of connecting rod 310, connecting rod 310 drives rubber ring cylinder 315 to expand, causing arc-shaped extrusion plate 310-1 to expand outward simultaneously. During the expansion, arc-shaped extrusion plate 310-1 extrudes the material, and under the combined action of high-pressure gas ejected from nozzle 308, the material moves upward between arc-shaped extrusion plate 310-1 and tank 101, causing the material at the bottom of tank 101 to surge upward. As the rubber annular cylinder 312 expands, it causes the inlet 313 to expand as well. This allows the material flowing up from the bottom of the tank 101 to enter the interior of the rubber annular cylinder 312 and the rubber annular cylinder 315 through the expanded inlet 313. Subsequently, the drive end of the driver 103 begins to contract, causing the driver 103 to drive the connecting rod 202 to move upward inside the tank 101. This causes the connecting rod 202 to drive the collar 204 to move upward synchronously, thereby causing the rubber annular cylinder 312 and the rubber annular cylinder 315 to contract under the action of elasticity. This reduces the internal space of the rubber annular cylinder 315 and the rubber annular cylinder 312, placing the material inside the rubber annular cylinder 315 and the rubber annular cylinder 312 in a relatively small space. This achieves the effect of separating a large amount of material into a small amount of material for mixing, avoiding the problem of insufficient mixing when there is too much material.

[0056] As the rubber annular cylinder 312 and the rubber annular cylinder 315 shrink due to their own contraction, the internal space of the rubber annular cylinder 312 and the rubber annular cylinder 315 becomes smaller. At this time, the operator sends a rotation command to the drive panel inside the driver 103 through the external controller, causing the drive end of the driver 103 to rotate in one direction. The driver 103 drives the collar 204 to rotate synchronously through the connecting rod 202. The collar 204 then abuts against the groove on the outer wall of the connecting rod 202-1 through the slider on the inner wall, causing the connecting rod 202-1 to rotate synchronously. The connecting rod 202-1 then drives the stirring rod 203 to rotate synchronously, causing the stirring rod 203 to stir the materials inside the rubber annular cylinder 315 and the rubber annular cylinder 312. Because the internal space of the rubber annular cylinder 312 and the rubber annular cylinder 315 has shrunk, the area of ​​material movement between them has decreased, thereby increasing the collision frequency between materials and improving the reaction process and uniformity between materials.

[0057] In the preliminary processing mechanism 200, the collar 204 drives the guide plate 205, which is tilted at 30 degrees, to rotate. The baffles 207 on the outer wall of the scraper 206, which are perpendicular to each other, shear and divert the material, breaking up the agglomerated asphalt particles. In conjunction with the rotating and stirring rods 203 in the annular array at the bottom of the connecting rod 202, the mixing uniformity of the modifier and the base asphalt is greatly improved. In addition, when the collar 204 drives the guide plate 205 to move downward, the annular rod 304 pushes the connecting rod 309 and the connecting rod 310, causing the rubber annular cylinder 315 to contract, reducing the material movement space and increasing the material collision frequency. At the same time, the connecting rod 202 drives the stirring rod 203 to stir the material in the rubber annular cylinder 312 and the rubber annular cylinder 315, accelerating the reaction process and shortening the reaction completion time.
