Description

Technical Field

[0001] This invention relates to the field of mixing reactor technology, and more specifically to a reaction vessel for the continuous production of asphalt mixture modifiers. Background Technology

[0002] Currently, various asphalt mixture modifier reaction vessels have been developed and applied in actual production. For example, Chinese patent CN211586607U discloses a typical reaction vessel structure, which includes a reaction vessel body, an openable sealing cover, a feed pipe set on the sealing cover, and a discharge pipe located on the reaction vessel body. The reaction vessel body adopts a jacketed sidewall composed of an outer wall and an inner wall, and is equipped with a heating component to heat the internal materials. At the same time, a stirring and temperature control component is installed on the sealing cover to achieve stirring and temperature control of the modifier raw materials.

[0003] However, in practical applications, it has been found that reactors using conventional stirring structures (such as vertically mounted straight-blade turbine stirrers) have significant technical limitations. These impellers mainly generate strong radial flow, throwing the fluid at high speed against the tank wall. The fluid then moves upward and downward along the wall, forming two relatively independent circulation loops. This flow field pattern easily creates "dead zones" with poor flowability in the top and bottom regions of the reactor, especially near the central axis. The existence of these dead zones leads to uneven mixing of materials, which may affect the homogeneity and quality stability of the modifier product. Furthermore, after the reaction process is completed, the high-viscosity slurry tends to adhere to the inner wall of the reactor. If it is not cleaned effectively, it will not only waste materials, but may also affect the quality of subsequent batches of products and the heat transfer efficiency of the reactor. An intuitive solution is to lengthen the impeller so that it can scrape against the inner wall of the tank when rotating. However, this method will significantly increase the rotational friction between the agitator and the wall, which will not only lead to a sharp increase in equipment energy consumption, but may also aggravate mechanical wear and shorten the service life of key components. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is: how to design a reaction vessel stirring structure that can flexibly switch between two working modes as needed, namely, efficient mixing and low-consumption cleaning of wall deposits, so as to balance mixing uniformity, cleaning effect and equipment energy consumption and lifespan.

[0005] The present invention provides the following technical solution: a reaction vessel for continuous production of asphalt mixture modifier, comprising a reactor body, a drive shaft disposed at its center, a base frame installed at the bottom of the reactor body, and a power system for coordinating the lifting and rotation of the drive shaft, wherein a slurry treatment system is provided inside the reactor body; The slurry processing system includes a bearing seat coaxially mounted with the drive shaft. Multiple beam arms are circumferentially fixed to the side wall of the bearing seat. One end of each beam arm near the side wall of the reactor body is vertically bent and a rotating ring is fixed to its top. A first wall scraping mechanism is provided between the beam arm and the rotating ring, circumferentially surrounding the drive shaft and engaging with it for transmission. At the same time, a turbine stirring mechanism is also mounted on the beam arm, circumferentially surrounding the drive shaft and engaging with it for push-pull transmission. The dual power transmission during the lifting and rotating of the drive shaft is achieved through the meshing transmission of the first wall scraping mechanism and the push-pull transmission of the turbine stirring mechanism. That is, by adjusting the tilt angle of the turbine stirring mechanism and the radial position of the first wall scraping mechanism, the system switches between the mixing mode and the scraping mode, realizing targeted mixing and scraping operations.

[0006] Furthermore, the beam arm includes a vertically extending longitudinal beam, the top of which is fixed to a rotatable rotating ring on the top of the reactor body. The inner side of the longitudinal beam is rigidly connected to a horizontally arranged frame. The other end of the frame is rigidly connected to a shaft seat coaxially arranged with the drive shaft. The shaft seat is movably penetrated by an upper rib segment on the surface of the drive shaft, and the two are vertically slidably arranged.

[0007] Furthermore, the first scraping mechanism includes a driven gear that meshes with a rack segment on the top surface of the drive shaft. The driven gear is rotatably mounted on the end of the positioning arm via a rotating shaft, and the other end of the positioning arm is rigidly fixed to the inner side of the rotating ring. A rocker arm is provided between the driven gear and the frame, and the two are coaxially fixedly connected. The bottom end of the rocker arm extends to the side wall of the frame at an inclined angle and is machined with a groove. The groove is movably fitted with a slider that slides on the slide rail of the side wall of the frame. A push rod is fixed near the side of the slider near the longitudinal beam, and the other end of the push rod is rigidly connected to the first scraper blade.

[0008] Furthermore, the turbine stirring mechanism includes turbine blades that can be rotatably arranged around the axis of the frame. The bottom of the turbine blades near the drive shaft is driven by the drive shaft through an angle adjustment part. The angle adjustment part can gradually tilt as the drive shaft is lifted to push the turbine blades to rotate around the axis to form a turbine.

[0009] Furthermore, the sidewall of the longitudinal beam is machined with a receiving groove for inserting the first scraper blade, and the sidewall of the receiving groove is provided with a guide groove for the push rod end to move.

[0010] Furthermore, the tilt adjustment unit includes two fixed supports, which are respectively fixed to the surface of the drive shaft and the bottom of the turbine blade sidewall. A hinge shaft is provided between the two fixed supports and both ends are hinged to it. The lower fixed support is raised together with the drive shaft, so that the hinge shaft tilts to one side to change the direction of force application, driving the turbine blade to adjust the tilt angle in the frame. The turbine is formed by multiple sets of circumferential turbine blades. When rotating, it pushes the fluid to move along the axial direction (up and down), and draws the fluid at the top and bottom into the main circulation, forming a large circulation that runs through the tank to eliminate the dead corner of the stirring.

[0011] Furthermore, the turbine blade has a flow-dividing cavity on the side near the longitudinal beam, which is connected to the turbine blade shaft tube; the longitudinal beam has a flow-guiding channel, the top of which is connected to a rotating ring, and a valve plate is installed at the bottom near the shaft tube, and a through hole is provided at the end of the shaft tube; when the turbine blade rotates to a vertical state, the through hole of the shaft tube is aligned with the valve plate, connecting the flow-guiding channel and the flow-dividing cavity to form a channel.

[0012] Furthermore, the turbine mixing mechanism also includes a distributor, which has multiple nozzles that communicate with the flow distribution chamber and are installed on its outer side, and is covered by a protective cover; an inclined baffle is fixed inside the frame to close the opening of the protective cover when the turbine blades tilt to enter the mixing mode.

[0013] Furthermore, a replenishment ring is provided at the top of the rotating ring, and the two are connected by a rotating seal. The replenishment ring is connected to an external cleaning agent source.

[0014] Furthermore, the reactor body includes a main tank and cover plates and discharge hoppers disposed at the upper and lower ends of the main tank.

[0015] The technical effects and advantages of this invention are as follows: This invention achieves synergistic optimization of mixing efficiency and cleaning effect through a dual-mode switching design (mixing mode and scraping mode). In mixing mode, the drive shaft lifts and drives the driven gear to rotate counterclockwise, causing the first scraper blade to detach from the inner wall of the main tank. At the same time, the tilt angle adjustment unit pushes the turbine blades to form a tilted turbine, creating a large axial circulation to eliminate dead zones in the mixing process. The nozzle is protected from clogging by the protective cover and baffle. In scraping mode, the drive shaft moves downward, causing the first scraper blade to contact the inner wall of the main tank. The turbine blade returns to its tilt angle. When the turbine blade rotates to a vertical position, the diversion channel and the flow distribution chamber form a liquid delivery channel through the valve plate through-hole. The cleaning agent is sprayed through the nozzle onto the path of the first scraper blade, achieving simultaneous scraping and cleaning. This design combines uniform mixing (vortex enhancement in mixing mode), thorough wall cleaning (dynamic spraying in scraping mode), and equipment life protection (sealed anti-clogging structure), significantly improving the efficiency of industrial slurry processing and equipment adaptability.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The reaction vessel for continuous production of asphalt mixture modifiers involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 13 The present invention provides a reactor for continuous production of asphalt mixture modifier, including a reactor body 1, a drive shaft 2 disposed at its center, a base frame 5 installed at the bottom of the reactor body 1, and a power system for coordinating the lifting and rotation of the drive shaft 2; the reactor body 1 is provided with a slurry treatment system 6. The slurry processing system 6 includes a bearing seat 61 coaxially mounted with the drive shaft 2. Multiple beam arms 62 are circumferentially fixed to the side wall of the bearing seat 61. One end of the beam arm 62 near the side wall of the reactor body 1 is bent vertically and a rotating ring 63 is fixed to its top. A first scraping mechanism 64 is provided between the beam arm 62 and the rotating ring 63, which circumferentially surrounds the drive shaft 2 and meshes with it. At the same time, a turbine stirring mechanism 65 is also mounted on the beam arm 62, which circumferentially surrounds the drive shaft 2 and pushes and pulls with it. The meshing transmission of the first scraping mechanism 64 and the push-pull transmission of the turbine stirring mechanism 65 work together to achieve dual power transmission when the drive shaft 2 is raised, lowered and rotated. That is, by adjusting the tilt angle of the turbine stirring mechanism 65 and the radial position of the first scraping mechanism 64, the system switches between the mixing mode and the scraping mode to achieve targeted mixing and scraping operations. The beam arm 62 includes a vertically extending longitudinal beam 621, the top of which is fixed to a rotatable rotating ring 63 on the top of the reactor body 1. The inner side of the longitudinal beam 621 is rigidly connected to a horizontally arranged frame 622. The other end of the frame 622 is rigidly connected to a bearing 61 coaxially arranged with the drive shaft 2. The bearing 61 is movably penetrated by the upper rib section 22 on the surface of the drive shaft 2. The two are vertically sliding to ensure that the drive shaft 2 can still drive the slurry treatment system 6 to rotate circumferentially along the inner cavity of the reactor body 1 when it moves up and down, thereby achieving stable mixing / scraping action. The first wall-scraping mechanism 64 includes a driven gear 645 that meshes with the rack segment 21 on the top surface of the drive shaft 2. The driven gear 645 is rotatably mounted on the end of the positioning arm 646 via a rotating shaft. The other end of the positioning arm 646 is rigidly fixed to the inner side of the rotating ring 63. A rocker arm 641 is provided between the driven gear 645 and the frame 622. The two are coaxially fixedly connected. The bottom end of the rocker arm 641 extends to the side wall of the frame 622 at an inclined angle and is machined with a groove. The groove slides with a slider 642 that slides on the slide rail on the side wall of the frame 622. The sliding block 642 is fixed with a push rod 643 near the longitudinal beam 621. The other end of the push rod 643 is rigidly connected to the first scraper blade 644. When the drive shaft 2 moves down, the rack segment 21 drives the driven gear 645 to rotate around the shaft end of the positioning arm 646, which drives the swing rod 641 to rotate clockwise. Its bottom groove forces the sliding block 642 to move outward along the slide rail of the frame 622. The push rod 643 pushes the first scraper blade 644 out of the receiving groove of the longitudinal beam 621, so that the first scraper blade 644 contacts the inner wall of the main tank 11 to achieve the wall scraping function. The turbine stirring mechanism 65 includes a turbine blade 652 that can be rotatably arranged around the axis of the frame 622. The bottom of the turbine blade 652 near the drive shaft 2 is driven by the drive shaft 2 through the tilt adjustment part 651. The tilt adjustment part 651 can gradually tilt as the drive shaft 2 is lifted to push the turbine blade 652 to rotate around the axis to form a turbine. In this embodiment, it should be specifically noted that the side wall of the longitudinal beam 621 is machined with a receiving groove for the insertion of the first scraper blade 644. The side wall of the receiving groove is provided with a guide groove for the end of the push rod 643 to move, so that when the push rod 643 retracts under the drive of the swing rod 641 and the slider 642, the first scraper blade 644 can be completely stored in the receiving groove of the side wall of the longitudinal beam 621, thus eliminating motion interference. The tilt adjustment unit 651 includes two fixed supports 6512, which are respectively fixed to the surface of the drive shaft 2 and the bottom of the side wall of the turbine blade 652. A hinge shaft 6511 is provided between the two fixed supports 6512 and is hinged to both ends. The lower fixed support 6512 is raised together with the drive shaft 2, so that the hinge shaft 6511 tilts to one side to change the direction of force application, and drives the turbine blade 652 to adjust the tilt angle within the frame 622. The turbine is formed by multiple sets of circumferential turbine blades 652. When rotating, it pushes the fluid to move up and down along the axial direction, and draws the fluid at the top and bottom into the main circulation, forming a large circulation that runs through the tank to eliminate the dead corner of the stirring. The drive shaft 2, the tilt adjustment part 651 and the turbine blade 652 are not in the same radial vertical plane, so that the tilt adjustment part 651 can gradually tilt as the drive shaft 2 is lifted to push the turbine blade 652 to rotate around the axis, thus avoiding motion interference. The power system for coordinating the lifting and rotation of the drive shaft 2 includes a telescopic cylinder 3 mounted on the top of the reactor body 1 and a rotary drive mechanism 4 mounted inside the base frame 5. The telescopic cylinder 3 is rigidly connected to the top end of the drive shaft 2, driving the drive shaft 2 to move up and down; The rotary drive mechanism 4 includes a transmission gear 41 coaxially arranged with the drive shaft 2, which is rotatably mounted inside the base frame 5 via a bracket. The transmission gear 41 is passed through the lower rib section 23 on the bottom surface of the drive shaft 2, and the two are vertically slidably connected. The side wall of the transmission gear 41 meshes with the drive gear 42, which is mounted on the output shaft of the motor 43. The motor 43 is fixed to the base frame 5. The motor 43 drives the drive gear 42 to rotate, and the torque is transmitted to the drive shaft 2 via the transmission gear 41. With the push-pull action of the telescopic cylinder 3 and the sliding arrangement of the lower rib section 23 and the transmission gear 41, the lifting and rotational movements of the drive shaft 2 do not interfere with each other. To improve the cleaning efficiency of the inner wall of the reactor body 1 under scraping mode, the structure of the turbine stirring mechanism 65 is optimized: a flow distribution cavity 6521 is provided in the turbine blade 652 near the longitudinal beam 621, which is connected to the shaft tube of the turbine blade 652; a flow guide channel 6211 is provided in the longitudinal beam 621, the top end of which is connected to the rotating ring 63, and a valve plate 6212 is installed at the bottom end near the shaft tube, and a through hole is provided at the end of the shaft tube; when the turbine blade 652 rotates to the vertical state, the through hole of the shaft tube is aligned with the valve plate 6212, connecting the flow guide channel 6211 and the flow distribution cavity 6521 to form a channel; The turbine mixing mechanism 65 further includes a distributor 653, which includes multiple nozzles 6531 that communicate with the flow distribution chamber 6521 and are installed on its outer side, and is covered by a protective cover 6532; an inclined baffle 6533 is fixed inside the frame 622 to close the opening of the protective cover 6532 when the turbine blades 652 are tilted into the mixing mode. The top of the rotating ring 63 is equipped with a supply ring 8, which is connected by a rotating seal. The supply ring 8 is connected to the external cleaning agent source (industrial grade asphalt cleaner).

[0033] Reference Figures 1 to 4 as well as Figure 14 In order to facilitate the maintenance of the inside of the reactor body 1 and to facilitate the mixing and discharging operations, the structure of the reactor body 1 is further optimized. Specifically, the reactor body 1 includes a main tank 11 and cover plates 13 and discharge hoppers 12 that are installed at the upper and lower ends of the main tank 11. The main tank 11 includes an upper and lower compartment, a transmission compartment 111, and a mixing compartment 112. The liquid level of the slurry in the tank is lower than that in the mixing compartment 112. The turbine stirring mechanism 65 and the first wall scraping mechanism 64 move in the mixing compartment 112, and the driven gear 645 is located in the transmission compartment 111. The discharge hopper 12 is an inverted cone shape, and its discharge port at the bottom is coaxial with the drive shaft 2. An outwardly inclined guide pipe is provided at the bottom of the discharge port to prevent falling material from contaminating the operation of the rotary drive mechanism 4. To further enhance the scraping ability of the inner wall of the discharge hopper 12 and increase the scraping area, the inner cavity of the discharge hopper 12 is provided with a second scraping mechanism 7 to enhance the scraping ability. The second scraping mechanism 7 includes a scraping ring 72 attached to the inner wall of the discharge hopper 12, and a scraping arm 71 extending circumferentially and converging in the center of the inner side of the scraping ring 72. The scraping arm 71 is provided with a mating interface for the drive shaft 2 to pass through. The surface of the drive shaft 2 is provided with a locking part 24 that can be connected to the mating interface. The locking part 24 includes a locking base 241 fixed to the surface of the drive shaft 2. The side wall of the locking base 241 is provided with circumferentially distributed cavities, in which springs 243 and retractable locking pins 242 are embedded. The outer end of the locking pin 242 is arc-shaped, and the plug at the inner end is movably engaged in the cavity. The side wall of the scraper arm 71 is provided with a groove that fits with the locking pin 242. The locking pin 242 and the side wall of the groove are smooth longitudinal sections. When the drive shaft 2 moves down, the locking pin 242 is constrained by the inner wall of the scraper arm 71 and squeezes the spring 243 into the cavity. When it is aligned with the groove, the locking pin 242 is inserted into the groove under the action of the spring 243's rebound force. Because the locking pin 242 abuts against the side wall of the groove, the drive shaft 2 can drive the second scraper mechanism 7 to rotate and scrape the material from the inner wall of the discharge hopper 12 through the locking part 24.

[0034] Working principle of this invention: The equipment has two working modes: mixing mode and scraping mode; it can flexibly switch between the two working modes of efficient mixing and low-consumption cleaning of wall deposits as needed, so as to balance the uniformity of mixing, cleaning effect, equipment energy consumption and lifespan. When the slurry in the reactor body 1 needs to be mixed, the mixing mode is activated, raising the drive shaft 2 to its highest point. The driven gear 645, meshed with the rack segment 21, drives the rocker arm 641 to rotate counterclockwise around the end of the positioning arm 646. The slide groove at the bottom of the rocker arm 641 guides the slider 642 to move towards the center along the slide rail on the side wall of the frame 622. The push rod 643 pulls the first scraper blade 644 into the receiving groove on the side wall of the longitudinal beam 621, causing the first scraper blade 644 to disengage from the inner wall of the main tank 11 and cancel the scraping effect. At the same time, the tilt adjustment part 651 tilts as the drive shaft 2 is raised, pushing the turbine blade 652 to rotate, thus constructing an inclined impeller turbine. Specifically, the fixed support 6512 below rises together with the drive shaft 2, guiding the hinge shaft 6511 to tilt to one side to change the direction of force application, pushing the turbine blades 652 to adjust to a 45-degree inclination angle within the frame 622. Multiple sets of circumferential turbine blades 652 form a flow-guiding turbine, which, when rotating, pushes the fluid up and down axially, drawing the fluid from the top and bottom into the main circulation, forming a large circulation throughout the tank to eliminate dead zones in the stirring process. When the turbine blades 652 reach their maximum inclination angle, the protective cover 6532 aligns with the baffle 6533, causing the baffle 6533 to close the opening of the protective cover 6532, forming a sealed chamber to protect the nozzle 6531 and prevent slurry blockage. Figure 9 Towards Figure 7 (State transition shown) When the mixing process is complete and the residue on the inner wall of the reactor body 1 needs to be cleaned, the equipment switches from the mixing mode to the scraping mode. The specific process is as follows: Activating the scraping mode causes the drive shaft 2 to move down to its lowest point. The driven gear 645, meshed with the rack segment 21, drives the swing arm 641 to rotate clockwise around the end of the positioning arm 646. The slide groove at the bottom of the swing arm 641 guides the slider 642 to move outward along the slide rail on the side wall of the frame 622. The push rod 643 pushes the first scraper blade 644 out of the receiving groove on the side wall of the longitudinal beam 621, causing the first scraper blade 644 to contact the inner wall of the main tank 11 to activate the wall scraping action. Simultaneously, the tilt adjustment part 651 moves down with the drive shaft 2, pulling the turbine blade 652 to rotate, canceling the tilted impeller turbine. Specifically, the lower fixed support 6512 descends along with the drive shaft 2, guiding the hinge shaft 6511 back to the vertical direction to pull... The turbine blade 652 is adjusted to a 0-degree inclination angle within the frame 622, so that the turbine blade 652 and the first scraper blade 644 are distributed on two staggered longitudinal sections. When the turbine blade 652 reaches the minimum inclination angle, the protective cover 6532 misaligns the baffle 6533, opening the protective cover 6532 to release the seal on the nozzle 6531. When the turbine blade 652 rotates to a vertical position, the through hole at the end of its shaft tube aligns with the valve plate 6212, thereby connecting the drainage channel 6211 and the diversion chamber 6521 to form a liquid delivery channel. At this time, the industrial-grade asphalt cleaner supplied by the replenishment ring 8 can be delivered to the nozzle 6531 through this liquid delivery channel and sprayed onto the cleaning path of the first scraper blade 644 by the nozzle 6531. With the continuous rotation of the slurry treatment system 6, the coordinated operation of spraying and scraping is achieved, significantly improving the cleaning effect. Figure 7 Towards Figure 9 (The state transition is shown).
