Description

A highly efficient and fully mixed reaction vessel Technical Field

[0001] This invention relates to the field of mixing reactor technology, and in particular to a highly efficient and thorough mixing reactor. Background Technology

[0002] The synthesis of high-viscosity materials typically involves multiple stages. Throughout the reaction cycle, the viscosity of the material often exhibits significant non-linear changes, especially in the later stages when diluents or additives are added, at which point the viscosity can reach tens of thousands of millipascals per second or even higher. This high viscosity and low flowability characteristic places extremely stringent requirements on the reaction vessel.

[0003] Currently, stirred reactors used in the production of high-viscosity materials mainly employ anchor, frame, or ribbon agitators. While these agitators can, to some extent, drive material flow near the wall and prevent localized overheating, they often suffer from low axial mixing efficiency in actual production. Specifically, the structural design of existing agitators is primarily based on radial and tangential flow, lacking effective axial pushing. Materials easily form laminar and dead zones within the reactor, with insufficient exchange between the upper and lower layers, leading to uneven temperature and concentration distribution within the reactor. Especially in the later stages of the reaction, after the addition of light component diluents, due to density differences and flow resistance, the diluents often float on the surface or seep down along the agitator shaft, making it difficult to achieve uniform distribution in a short time, ultimately causing horizontal stratification within the same batch of product. Summary of the Invention

[0004] The purpose of this invention is to provide a highly efficient and fully mixing reactor to solve the problems existing in the prior art, and to effectively solve the problem of easy stratification and deposition in traditional reactors under high viscosity conditions.

[0005] To achieve the above objectives, the present invention provides the following solution: The present invention provides a highly efficient and thorough mixing reactor, comprising a reactor body, a stirring mechanism and a driving mechanism respectively disposed inside and outside the reactor body; the stirring mechanism includes a driving shaft, a vertical conveying mechanism and multiple dispersing mechanisms; one end of the driving shaft is located outside the reactor body and is drivenly connected to the driving mechanism, and the other end rotatably extends into the reactor body; the vertical conveying mechanism includes a lifting cylinder, which is drivenly connected to the end of the driving shaft extending into the reactor body and rotates synchronously with the driving shaft; the lifting cylinder... The inner wall of the lifting cylinder is provided with spiral blades, which extend spirally from bottom to top and surround the outer periphery of the drive shaft. The radial cross-section of the lifting cylinder gradually decreases from bottom to top. Multiple discharge ports are opened on the cylinder wall of the lifting cylinder, and the discharge ports are arranged sequentially in the vertical direction. The bottom end of the lifting cylinder extends to the bottom of the inner side of the reactor. Each of the dispersion mechanisms surrounds the outer peripheral wall of the lifting cylinder and is located between the outer peripheral wall of the lifting cylinder and the inner peripheral wall of the reactor body. The dispersion mechanisms are arranged sequentially in the vertical direction and are respectively set below the discharge ports of each layer.

[0006] Optionally, the pitch of the helical blades gradually decreases from bottom to top.

[0007] Optionally, the surface of the spiral blade is provided with a plurality of flow guide holes, and the diameter of each flow guide hole gradually decreases from bottom to top.

[0008] Optionally, the lifting cylinder has multiple discharge ports on its wall, with each layer of discharge ports arranged sequentially in the vertical direction. Each layer has multiple discharge ports, and each discharge port is arranged sequentially along the circumference of the lifting cylinder.

[0009] Optionally, each layer of the discharge port is provided with a downwardly inclined guide plate at its upper edge, the guide plate extending above the corresponding dispersing mechanism.

[0010] Optionally, the dispersing mechanism includes an annular mounting base and multiple blades. The annular mounting base is sleeved on the outer periphery of the lifting cylinder. The root of the blade is mounted on the outer periphery of the annular mounting base, and the tip of the blade extends to the inner periphery of the reactor body.

[0011] Optionally, the root of the blade is omnidirectionally mounted on the outer peripheral wall of the annular mounting base, and an elastic reset element is connected between the blade and the outer peripheral wall of the annular mounting base.

[0012] Optionally, the tip of the blade is connected to a shearing blade, and the shearing blade has a cutting edge on the side near the inner peripheral wall of the reactor body. The cutting edge has an arc-shaped structure that fits against the inner peripheral wall of the reactor body, and its extension direction is angularly distributed with respect to the axial direction of the reactor body.

[0013] Optionally, the back of the blade is provided with guide ribs, which extend in the same direction as the blade.

[0014] Optionally, the inner peripheral wall of the reactor body is provided with an array of shearing protrusions, each of which extends vertically and is evenly distributed along the circumference of the reactor body. The blade abuts against the shearing protrusions at a position away from the inner peripheral wall of the reactor body and slides in contact with them.

[0015] This invention achieves the following technical advantages over existing technologies: The highly efficient and fully mixing reactor disclosed in this invention uses a drive mechanism to drive the drive shaft and the lifting cylinder to rotate synchronously. Spiral blades on the inner wall of the lifting cylinder drive the material at the bottom of the reactor body upwards along the axial direction of the lifting cylinder. Because the radial cross-section of the lifting cylinder gradually decreases from bottom to top, the material is continuously compressed and accelerated during its ascent, significantly enhancing the kinetic energy and penetrating power of the material along the axial direction of the lifting cylinder. When the high-speed rising material flows through the discharge ports on the lifting cylinder, it is forcibly sprayed into the annular area between the outer peripheral wall of the lifting cylinder and the inner peripheral wall of the reactor body, and evenly distributed to the dispersion mechanism corresponding to each discharge port. During the rotation of the lifting cylinder, the dispersion mechanism stirs and radially disperses the sprayed material, further dispersing it to the sidewall area of ​​the reactor. This effectively solves the problem of easy stratification and deposition in traditional reactors under high viscosity conditions. Through the lifting cylinder and the dispersion mechanism, forced convection is formed in the vertical direction, eliminating horizontal stratification, and continuous radial transport from the center to the sidewall is achieved, eliminating internal and external stratification. Meanwhile, the corresponding arrangement of the multi-level discharge ports and the dispersion mechanism ensures that uniform material mixing can be achieved in different height areas within the reactor, significantly improving overall mixing efficiency and product consistency.

Detailed Implementation

[0018] 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 scope of protection of the present invention.

[0019] The purpose of this invention is to provide a highly efficient and fully mixing reactor to solve the problems existing in the prior art, and to effectively solve the problem of easy stratification and deposition in traditional reactors under high viscosity conditions.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] As shown in Figures 1 to 4, the present invention provides a highly efficient and thorough mixing reactor, comprising a reactor body 2, a stirring mechanism and a driving mechanism 1 respectively disposed inside and outside the reactor body 2; the stirring mechanism includes a driving shaft 3, a vertical conveying mechanism and multiple dispersing mechanisms; one end of the driving shaft 3 is located outside the reactor body 2 and is connected to the driving mechanism 1, and the other end rotatably extends into the reactor body 2. It is understood that the driving shaft 3 and the reactor body 2 are rotaryly sealed, for example, a shaft seal can be used; the vertical conveying mechanism includes a lifting cylinder 6, which is connected to the end of the driving shaft 3 that extends into the reactor body 2. The lifting cylinder 6 rotates synchronously with the drive shaft 3. The inner wall of the lifting cylinder 6 is provided with spiral blades 8, which extend spirally from bottom to top and surround the outer periphery of the drive shaft 3. The radial cross section of the lifting cylinder 6 gradually decreases from bottom to top. Multiple discharge ports 7 are opened on the cylinder wall of the lifting cylinder 6, and each discharge port 7 is arranged in sequence along the vertical direction. The bottom end of the lifting cylinder 6 extends to the bottom of the inner side of the reactor. Each dispersion mechanism is surrounded on the outer periphery of the lifting cylinder 6 and located between the outer periphery of the lifting cylinder 6 and the inner periphery of the reactor body 2. Each dispersion mechanism is arranged in sequence along the vertical direction and is respectively set below each layer of discharge port 7.

[0022] Regarding the rotational arrangement of the lifting cylinder 6, in some cases, the lifting cylinder 6 adopts a cantilever installation structure, with its top end rotatably suspended at the top position of the lifting cylinder 6. For example, a top support frame 4 is provided inside the top of the lifting cylinder 6, and the top end of the lifting cylinder 6 passes through the top support frame 4 from above, with an annular protrusion overlapping the top support frame 4. The annular protrusion is located above the top support frame 4, and a rotating component, such as a rolling bearing, is provided between the annular protrusion and the top support frame 4. A guide ring is fitted at the bottom of the lifting cylinder 6. The guide ring is made of wear-resistant material, and its outer edge maintains a 10mm annular gap with the bottom inner wall of the reactor body 2. During operation, the main shaft drives the lifting cylinder 6 to rotate synchronously, and the lifting cylinder 6 is suspended on the top support frame 4 in a cantilever state, with its bottom end hanging freely. Under normal operating conditions, the guide ring maintains a gap with the inner wall of the reactor body 2, and only plays a limiting role when the lifting cylinder 6 swings abnormally, preventing the lifting cylinder 6 from rigidly colliding with the reactor body.

[0023] In other cases, the rotating arrangement of the lifting cylinder 6 employs a double-end support structure installed within the reactor body 2. The bottom end of the lifting cylinder 6 has a bottom support ring, and a bottom support seat 12 is fixedly installed at the bottom of the reactor body 2. A bottom bearing is located between the bottom support ring and the bottom support seat 12 to bear the weight of the lifting cylinder 6 and provide radial positioning. It is understood that both the bottom support ring and the bottom support seat 12 are hollow structures to facilitate material flow through them to the bottom of the lifting cylinder 6. The top end of the lifting cylinder 6 extends outward to form a top flange. A top support frame 4 is fixedly installed at the top of the reactor body 2, and a top bearing, using a self-aligning roller bearing, is located between the top flange and the top support frame 4, allowing axial displacement of the lifting cylinder 6 due to thermal expansion. A drive ring is fixedly installed on the main shaft, and the drive ring is fixedly connected to the top flange via multiple circumferentially spaced connecting ribs to achieve torque transmission. A sealing structure is provided between the top end of the lifting cylinder 6 and the main shaft to prevent material from flowing upwards along the main shaft. During operation, the main shaft drives the lifting cylinder 6 to rotate synchronously through the drive ring and connecting rib plate. The lifting cylinder 6 maintains stable rotation under the joint constraint of the bottom bearing and the top bearing. The bottom support structure bears the gravity, and the top self-aligning bearing compensates for thermal expansion, ensuring that the lifting cylinder 6 maintains coaxiality with the main shaft throughout the entire temperature range.

[0024] Based on the above two situations, the top support frame 4 is a hollow structure to facilitate the passage of materials.

[0025] Based on the above implementation method, the drive mechanism 1 adopts a drive motor, which is set above the reactor body 2. The top end of the drive shaft 3 is located outside the reactor body 2 and is connected to the output end of the drive motor. Its bottom end rotates and extends into the reactor body 2.

[0026] Specifically, for the feeding and discharging of the reactor body 2, the top of the reactor body 2 is provided with a feed inlet 10, which is located on one side of the drive mechanism 1, and the bottom of the reactor body 2 is provided with a discharge outlet 11.

[0027] In some operating conditions, the material in the reactor body 2 needs to be heated. In a specific example, the outer peripheral wall of the reactor body 2 is provided with an annular jacket, which is connected to a heat exchange mechanism. The heat exchange mechanism heats the heat exchange medium and provides a heat exchange medium, such as steam or thermal oil, to the annular jacket to heat the material. Accordingly, a temperature sensor is provided in the reactor body 2 to monitor the temperature of the material in the reactor body 2 through a controller, thereby adjusting the opening and closing of the heating mechanism or its operating efficiency.

[0028] To facilitate understanding of the effects of material mixing, in some examples, an inlet is provided at the top of the outer peripheral wall of the reactor body 2, and sealed with a transparent plate. This not only allows observation of the mixing process within the reactor body 2 through the inlet, but also prevents material adhesion from affecting observation by placing the inlet at the top of the reactor body 2, above the material.

[0029] This invention discloses a highly efficient and fully mixing reactor. Its driving mechanism 1 drives the driving shaft 3 and the lifting cylinder 6 to rotate synchronously. Spiral blades 8 on the inner wall of the lifting cylinder 6 drive the material at the bottom of the reactor body 2 upwards along the axial direction of the lifting cylinder 6. Because the radial cross-section of the lifting cylinder 6 gradually decreases from bottom to top, the material is continuously compressed and accelerated during its ascent, significantly enhancing the kinetic energy and penetrating power of the material along the axial direction of the lifting cylinder 6. When the high-speed rising material flows through the discharge ports 7 on the lifting cylinder 6, it is forcibly sprayed into the annular area between the outer peripheral wall of the lifting cylinder 6 and the inner peripheral wall of the reactor body 2, and evenly distributed to the dispersion mechanism corresponding to each discharge port 7. During the rotation of the lifting cylinder 6, the dispersion mechanism stirs and radially disperses the sprayed material, further dispersing it to the side wall area of ​​the reactor. This effectively solves the problem of easy stratification and deposition in traditional reactors under high viscosity conditions. Through the lifting cylinder 6 and the dispersion mechanism, forced convection is formed in the vertical direction, eliminating horizontal stratification, and continuous radial transport from the center to the side wall is achieved, eliminating internal and external stratification. Meanwhile, the corresponding arrangement of the multi-level discharge ports 7 and the dispersion mechanism ensures that uniform material mixing can be obtained in different height areas within the reactor, significantly improving overall mixing efficiency and product consistency.

[0030] To further improve the spraying effect of the material at the discharge port 7, in some embodiments, the pitch of the spiral blades 8 gradually decreases from bottom to top. During operation, due to the larger pitch at the bottom of the spiral blades 8, the material is initially pushed by the large-pitch spiral blades 8 at the bottom of the lifting cylinder 6, resulting in a larger axial displacement per unit number of rotations. This facilitates the rapid input of the material from the bottom into the lifting cylinder 6. As the material moves upward along the lifting cylinder 6, the pitch of the spiral blades 8 gradually decreases, and the density of the axial thrust applied to the material per unit number of rotations gradually increases. The material is further compressed and accelerated within the narrow channel, creating a pressurization effect. This allows the material to obtain continuously increasing axial kinetic energy during its ascent, compensating for the velocity attenuation caused by wall friction in high-viscosity materials. This ensures that the material reaches the discharge port 7 at a sufficient speed and is effectively sprayed, while simultaneously avoiding stagnation and backflow caused by uneven flow velocity within the lifting channel.

[0031] The spiral blade 8 has multiple guide holes running through its surface, with the diameter of each hole gradually decreasing from bottom to top. It is understood that when the spiral blade 8 rotates and pushes material, some material passes through the guide holes under the pressure of the spiral blade 8, forming a local jet perpendicular to the main flow direction. The large-diameter guide holes at the bottom allow more material to pass through, creating strong disturbance at the beginning of the lifting process; the small-diameter guide holes at the top increase the flow velocity of material passing through the spiral blade 8, forming a fine jet that further disperses the rising material flow. Thus, without increasing energy consumption, the mixing uniformity of the material during the lifting process is significantly improved, effectively preventing the formation of an adhesion layer on the surface of the spiral blade 8, while also promoting the interpenetration between materials of different viscosities.

[0032] The structure of the discharge port 7 varies depending on the material. It can be a single layer of discharge ports 7 at the top of the lifting cylinder 6, or multiple layers evenly distributed at the upper part of the lifting cylinder 6, or multiple layers evenly spaced vertically along the lifting cylinder 6. Of course, it is not limited to the above methods.

[0033] In a specific example, the lifting cylinder 6 has multiple layers of discharge ports 7 on its wall. Each layer of discharge ports 7 is arranged vertically, with multiple discharge ports 7 within each layer, arranged circumferentially around the lifting cylinder 6. When material is pushed to the discharge ports 7 within the lifting cylinder 6, it is subjected to the combined effects of centrifugal force and axial pressure, and is evenly distributed to the outside of the lifting cylinder 6. The vertical arrangement of the multiple layers of discharge ports 7 enables layered output of material across the entire height range; the circumferentially uniform arrangement of each layer of discharge ports 7 ensures the uniform distribution of material in the horizontal direction, thereby transforming the continuous axial flow into a discrete radial jet.

[0034] To enhance the dispersing mechanism's effectiveness on materials, each discharge port 7 has a downward-sloping guide plate at its upper edge, extending above the corresponding dispersing mechanism. The material ejected at high speed from the discharge port 7 slides down the inclined surface of the guide plate, distributing evenly to the dispersing mechanism below. In some specific examples, the inclination angle of the guide plate is designed according to different operating conditions, ensuring the material flows to the dispersing mechanism at the optimal incident angle. This avoids splashing and rebounding caused by the material falling vertically, while ensuring the material accurately covers the effective radius of the dispersing mechanism. This, in turn, straightens the material flow and buffers its kinetic energy, allowing the high-speed ejected material flow to smoothly transition to the dispersing and shearing stage, thus improving the efficiency and uniformity of the dispersing mechanism.

[0035] The dispersion mechanism includes an annular mounting base and multiple blades 5. The annular mounting base is fitted onto the outer periphery of the lifting cylinder 6. The roots of the blades 5 are mounted on the outer peripheral wall of the annular mounting base, and the tips of the blades 5 extend to the inner peripheral wall of the reactor body 2. The annular mounting base rotates synchronously with the lifting cylinder 6, causing the blades 5 to move circumferentially within the annular area between the lifting cylinder 6 and the inner wall of the reactor. During rotation, the blades 5 thoroughly shear and radially scatter the material sprayed from the discharge port 7 and falling along the guide plate, and forcibly push the material concentrated near the lifting cylinder 6 to the side wall area of ​​the reactor. This achieves radial material transport from the center to the edge, and the extension of the blade tips to the near-wall area effectively disturbs the boundary layer near the inner peripheral wall of the reactor body 2, further improving the disturbance effect.

[0036] Based on the above implementation method, the root of the impeller 5 is omnidirectionally mounted on the outer peripheral wall of the annular mounting base, and an elastic reset element is connected between the impeller 5 and the outer peripheral wall of the annular mounting base. During operation, the impeller 5 is subjected to the combined action of material resistance and centrifugal force, and can automatically adjust its angle of attack around the omnidirectional connection point, so that the impeller 5 always maintains the optimal angle of attack under different viscosity conditions. When the material viscosity increases, the resistance increases, and the angle of attack of the impeller 5 automatically decreases to avoid overload; when the material viscosity decreases, the elastic reset element pushes the impeller 5 back to a larger angle of attack to maintain sufficient stirring intensity. This allows the dispersion mechanism to maintain efficient shearing and scattering performance throughout the entire reaction process, while reducing the impact load on the stirring shaft and extending the service life of the equipment.

[0037] In order to allow the root of the blade 5 to be omnidirectionally mounted on the outer peripheral wall of the annular mounting base, the root of the blade 5 is connected to the annular mounting base through a universal joint or a spherical hinge.

[0038] The selection of the elastic reset element can be a spring or a tension spring, but is not limited to the above selections.

[0039] In another embodiment, the tip of the blade 5 is connected to a shearing blade 9. The shearing blade 9 has a cutting edge on the side near the inner peripheral wall of the reactor body 2. The cutting edge has an arc-shaped structure that fits against the inner peripheral wall of the reactor, and its extension direction is angularly distributed with respect to the axial direction of the reactor body 2. As the shearing blade 9 rotates with the blade 5, its cutting edge forms a sliding contact with the inner wall of the reactor. Firstly, it continuously scrapes and peels off the material adhering to the inner wall. Secondly, it further shears the material that has been dispersed to the inner peripheral wall of the reactor body 2 by the dispersion mechanism. That is, it performs shearing action between the cutting edge and the inner peripheral wall of the reactor body 2.

[0040] To improve the energy utilization efficiency of the blade 5 and reduce unnecessary turbulent dissipation, in one embodiment, guide ribs are provided on the back of the blade 5. The guide ribs extend in the same direction as the blade 5. First, it should be noted that when the blade 5 rotates in the material, a low-pressure zone is formed on the back of the blade 5, which can easily lead to material separation and cavitation. The guide ribs disrupt the continuity of the low-pressure zone, guide the material to flow orderly along the surface of the guide ribs, and fill the gaps that might otherwise appear. At the same time, the guide ribs increase the structural rigidity of the back of the blade 5, preventing the thin-walled blade 5 from twisting and deforming in high-viscosity materials.

[0041] In this invention, the back of the blade 5 is provided with guide ribs, which optimizes the flow state of the back surface of the blade 5 from the perspective of fluid mechanics, improves the energy utilization efficiency of the blade 5, reduces unnecessary turbulence dissipation, and allows more input power to be converted into effective shearing and pushing action.

[0042] In one embodiment, shearing ribs 13 are arrayed on the inner peripheral wall of the reactor body 2. Each shearing rib 13 extends vertically and is evenly distributed along the circumference of the reactor body 2. The blade abuts against the shearing rib 13 at a position away from the inner peripheral wall of the reactor body 2 and slides in contact with it. When the blade of the shearing blade 9 passes over the shearing rib 13, the material is subjected to strong compression and shearing action in the narrow gap between the blade and the rib, forming a local high-shear zone, effectively breaking down any gel particles or agglomerates that may be present in the material. Furthermore, the shearing ribs 13 facilitate the material to slide down the inner peripheral wall of the reactor body 2, preventing the material from adhering to the inner peripheral wall of the reactor body 2. This significantly improves the mixing effect of the reactor body 2 on high-viscosity materials and is suitable for the production of high-quality materials requiring high-shear dispersion.

[0043] Any adaptive changes made according to actual needs are within the scope of protection of this invention.

[0044] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description.

Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope.
