Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, and in particular relates to a reaction vessel based on shaking mixing. Background Technology

[0002] Reactors are indispensable equipment in chemical, pharmaceutical, food, and materials science fields, widely used in various chemical reactions, mixing, dissolution, and extraction processes. They are designed to provide a closed and controlled environment to ensure efficient and stable reactions of reactants under specific temperature, pressure, and stirring conditions. Reactors utilize internal stirring devices, such as paddle, anchor, or turbine stirrers, to achieve uniform mixing and effective dispersion of reactants, thereby accelerating the reaction process and improving product quality and yield. Furthermore, reactors are equipped with auxiliary equipment such as heating / cooling systems, pressure control systems, and safety valves to ensure the safety and controllability of the reaction process.

[0003] Existing reactors mainly rely on internal mechanical stirring devices to achieve material mixing. When dealing with materials that are highly viscous, prone to agglomeration, or require special mixing methods, a single stirring method may not achieve the desired effect. Traditional mechanical stirring devices mainly rely on the rotation of impellers, anchors, or turbines to generate shear and centrifugal forces, thereby driving the materials to mix. However, when materials have special physical properties, such as high viscosity, easy formation of agglomerates, or the need for specific hybrid dynamics to promote uniform dispersion, a single stirring method may not provide sufficient mixing energy or power to break down the internal structure and local agglomeration of these materials, resulting in poor mixing effect and potentially limiting reaction rate and product quality.

[0004] To address this issue, we propose a reaction vessel based on shaking and mixing. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the reaction rate is slow when using a single stirring method to process materials with special physical properties in the prior art, and to propose a reaction vessel based on shaking and mixing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reaction vessel based on shaking mixing includes a mounting frame, a guide ring, a reaction vessel, a stirring shaft, and a power assembly, wherein:

[0008] The mounting frame includes a base frame and two rectangular frames that are vertically mounted on the base frame;

[0009] The guide ring has two parts, which are rotatably disposed within two rectangular frames, and the two guide rings are coaxial.

[0010] The reaction vessel is installed at an incline between two guide rings. The reaction vessel is connected to the guide rings by a movable connector. When the guide rings rotate, the reaction vessel makes a conical pendulum motion with the geometric center as the center.

[0011] The stirring shaft is coaxially installed through the reaction vessel, and stirring blades for stirring materials are provided on the stirring shaft. A self-driving structure is provided at the end of the stirring shaft.

[0012] The power assembly is used to drive the two guide rings to rotate synchronously.

[0013] Preferably, the outer circumferential surface of the guide ring is provided with an annular groove, a toothed ring is provided in the annular groove, and multiple gears are rotatably installed in the rectangular frame. The gears are embedded in the annular groove and mesh with the toothed ring.

[0014] Preferably, the movable connector includes an eccentrically mounted mounting sleeve inside the guide ring, the mounting sleeves inside the two guide rings are in a centrally symmetrical state, and a connecting post is provided at both ends of the reaction vessel, the connecting post being movably connected to the mounting sleeve.

[0015] Preferably, the inner wall of the mounting sleeve is spherical, and the end of the connecting column has a spherical end cap adapted to the inner wall of the mounting sleeve, wherein the spherical end cap is movably fitted with the inner wall of the mounting sleeve.

[0016] Preferably, the mounting sleeve is provided with multiple sets of balls, which abut against the surface of the spherical end cap.

[0017] Preferably, the power assembly includes a motor mounted on the base frame, and a drive shaft is fixedly mounted on the output end of the motor. The drive shaft passes through gears at the same position on the two rectangular frames and is used to synchronously drive the gears on the different rectangular frames to rotate synchronously.

[0018] Preferably, the self-driving structure includes a mounting ring fixedly disposed on one of the rectangular frames, a helical tooth ring disposed on the inner side of the mounting ring, and a helical gear that meshes with the helical tooth ring is mounted on one end of the stirring shaft near the helical tooth ring.

[0019] In summary, the technical effects and advantages of this utility model are as follows: The reaction vessel in this shaking-mixing reactor undergoes a conical pendulum motion driven by a guide ring, shaking the materials within. Due to the horizontal design of the reaction vessel, the materials move more freely in both directions during shaking. This dynamic mixing method effectively breaks through the limitations of traditional static or single-stirring methods, allowing the materials to be more fully mixed and dispersed in three-dimensional space. Simultaneously, the stirring blades on the stirring shaft rotate synchronously under the drive of the self-driven structure, further enhancing the mixing effect, accelerating the reaction process, and improving reaction efficiency and product quality. The design of this reactor fully considers the diversity of material properties; whether it is low-viscosity fluids, high-viscosity materials, or easily agglomerated solid particles, effective mixing can be achieved through the synergistic effect of conical pendulum motion and mechanical stirring, giving this reactor broad application prospects in multiple fields.

Detailed Implementation

[0027] Reference Figure 1-4 A reaction vessel based on shaking mixing includes a mounting frame 1, a guide ring 2, a reaction vessel 3, a stirring shaft 4, and a power assembly 5.

[0028] Mounting frame 1 includes a base frame 11 and two rectangular frames 12 that are vertically mounted on the base frame 11. Both the base frame 11 and the rectangular frames 12 are made of channel steel and are parallel to each other.

[0029] There are two guide rings 2, which are rotatably set in two rectangular frames 12 respectively, and the two guide rings 2 are in a coaxial state. Driven by the power component 5, the two guide rings 2 rotate synchronously.

[0030] Reference Figure 1-4 The outer circumferential surface of the guide ring 2 is provided with an annular groove, and a toothed ring 21 is provided in the annular groove. Multiple gears 13 are rotatably installed in the rectangular frame 12. The gears 13 are engaged in the annular groove and mesh with the toothed ring 21. In this embodiment, four gears 13 are provided and are respectively installed at the four corners of the rectangular frame 12. The guide ring 2 is supported by multiple gears 13, and the guide ring 2 can rotate stably with the cooperation of the gears 13 and the toothed ring 21. At the same time, the gears 13 are engaged in the annular groove, which plays a role in limiting the axis of the guide ring 2 and preventing the guide ring 2 from axially deviating.

[0031] The reaction vessel 3 is installed at an angle between two guide rings 2. The reaction vessel 3 and the guide rings 2 are connected by a movable connector. The geometric center of the reaction vessel 3 is located on the axis of the guide rings 2. When the guide rings 2 rotate, the reaction vessel 3 makes a conical pendulum motion with the geometric center as the center.

[0032] Traditional reactors rely on the rotation of impellers, anchors, or turbines to generate shear and centrifugal forces, thereby driving the materials to mix. However, for materials with high viscosity, prone to agglomeration, or requiring specific hybrid dynamics to promote uniform dispersion, a single stirring method cannot provide sufficient mixing energy to break down the internal structure and localized agglomeration, resulting in poor mixing and potentially limiting the reaction rate and product quality. When the reaction vessel 3 performs a conical pendulum motion, the tilted reaction vessel 3 swings left and right, with its two ends alternately at high and low positions. The materials inside the reaction vessel 3 will then sway and mix from side to side. Because the reaction vessel 3 is horizontally designed, the materials have a larger range of movement when swaying. This dynamic mixing method effectively breaks the mixing limitations of traditional static or single stirring methods, allowing the materials to be more fully mixed and dispersed in three-dimensional space.

[0033] A feed pipe 33 is provided on one side of the reaction vessel 3. In this embodiment, the feed pipe 33 is used for adding and discharging materials. Under the action of the movable connector, the reaction vessel 3 can rotate around its own axis. When adding materials, the power component 5 drives the reaction vessel 3 to rotate so that the end of the reaction vessel 3 with the feed pipe 33 is in a high position. Then, the feed pipe 33 is rotated so that the opening faces upward. At this time, the feed pipe 33 is in the highest position, which is convenient for adding materials. When discharging materials, the power component 5 drives the reaction vessel 3 to rotate so that the end of the reaction vessel 3 with the feed pipe 33 is in a low position. Then, the feed pipe 33 is rotated so that the opening faces downward. At this time, the feed pipe 33 is in the lowest position, which is convenient for discharging materials. If it is necessary to connect upstream and downstream equipment, feed pipes 33 can be provided at both ends of the reaction vessel 3. One feed pipe 33 is connected to the upstream feeding equipment with its opening facing upward, and the other feed pipe 33 is connected to the downstream equipment with its opening facing downward. When the reaction vessel 3 is shaken, the opening direction of the feed pipe 33 remains unchanged under the action of the movable connector.

[0034] Reference Figure 2-6 The movable connecting component includes an eccentrically mounted mounting sleeve 22 inside the guide ring 2. The mounting sleeves 22 inside the two guide rings 2 are in a centrally symmetrical state. Both ends of the reaction vessel 3 are provided with connecting posts 31. The connecting posts 31 are movably connected to the mounting sleeves 22. The connecting posts 31 are locked inside the mounting sleeves 22. As the eccentrically mounted mounting sleeves 22 rotate with the guide ring 2, the position of the end of the reaction vessel 3 changes continuously. With the geometric center of the reaction vessel 3 as the vertex, both ends of the reaction vessel 3 rotate eccentrically at the same time to form a conical pendulum motion.

[0035] The inner wall of the mounting sleeve 22 is spherical, and the end of the connecting column 31 has a spherical end cap 32 that is adapted to the inner wall of the mounting sleeve 22. The spherical end cap 32 is movably fitted with the inner wall of the mounting sleeve 22, so the spherical end cap 32 can move in any direction on the inner wall of the mounting sleeve 22. When the reaction vessel 3 makes a conical pendulum motion, the reaction vessel 3 can continuously adjust its own position to keep the position of the feed pipe 33 stable. When the guide ring 2 rotates, the reaction vessel 3 does not rotate, ensuring that the position of the feed pipe 33 will not change due to the rotation of the reaction vessel 3.

[0036] Multiple sets of ball bearings 23 are provided inside the mounting sleeve 22. The ball bearings 23 abut against the surface of the spherical head 32. By setting the ball bearings 23, it is beneficial to reduce the friction between the mounting sleeve 22 and the spherical head 32, reduce wear, and improve the flexibility of the movement between the spherical head 32 and the inner wall of the mounting sleeve 22.

[0037] Reference Figure 2-6The stirring shaft 4 is coaxially installed through the reaction vessel 3. The stirring blades 41 for stirring materials are installed on the stirring shaft 4. The stirring blades 41 are spirally arranged and are multi-segmented. The rotation of the stirring blades 41 can mechanically mix the materials. The segmented arrangement is conducive to the materials impacting the stirring blades 41 when the reaction vessel 3 is shaken, so as to achieve full mixing. The end of the stirring shaft 4 is provided with a self-driving structure. Through the self-driving structure, the stirring shaft 4 can rotate when the reaction vessel 3 is in conical pendulum motion. Effective mixing is achieved through the synergistic effect of conical pendulum motion and mechanical stirring.

[0038] The self-driving structure includes a mounting ring 14 fixedly mounted on one of the rectangular frames 12. A helical gear ring 15 is provided on the inner side of the mounting ring 14. A helical gear 42 that meshes with the helical gear ring 15 is mounted on one end of the stirring shaft 4 near the helical gear ring 15. The helical gear ring 15 and the helical gear 42 coincide with the path of the reaction vessel 3 as it performs a conical pendulum motion. Therefore, the helical gear 42 always meshes with the helical gear ring 15 during the conical pendulum motion, thereby driving the stirring shaft 4 to rotate.

[0039] The power assembly 5 is used to drive the two guide rings 2 to rotate synchronously. The power assembly 5 includes a motor 51 mounted on the base frame 11. A drive shaft 52 is fixedly mounted on the output end of the motor 51. After the motor 51 is started, the drive shaft 52 starts to rotate. The drive shaft 52 passes through gears 13 at the same position on the two rectangular frames 12, and is used to synchronously drive the gears 13 on the different rectangular frames 12 to rotate synchronously. The drive shaft 52 drives the two gears 13 to rotate at the same time, so that the two guide rings 2 rotate in the same direction and at the same speed, thereby driving the reaction vessel 3 to shake.

[0040] Working principle:

[0041] In use, materials are added through the feed pipe 33, and the motor 51 is started. After the motor 51 starts, the drive shaft 52 starts to rotate. The drive shaft 52 simultaneously drives the two gears 13 to rotate, so that the two guide rings 2 rotate in the same direction and at the same speed. As the eccentrically set mounting sleeve 22 rotates with the guide rings 2, the position of the end of the reaction tank 3 changes continuously. With the geometric center of the reaction tank 3 as the vertex, the two ends of the reaction tank 3 rotate eccentrically at the same time to form a conical pendulum motion. The tilted reaction tank 3 swings left and right, and the two ends of the reaction tank 3 alternately occupy the high and low positions. The materials in the reaction tank 3 will shake and mix left and right in the reaction tank 3.

[0042] Meanwhile, the helical gear ring 15 and the helical gear 42 coincide along the path of the conical pendulum motion of the reaction vessel 3. The helical gear 42 always meshes with the helical gear ring 15 during the conical pendulum motion, thereby driving the stirring shaft 4 to rotate. The material can be mechanically mixed by the rotation of the stirring blade 41. Effective mixing is achieved through the synergistic effect of the conical pendulum motion and mechanical stirring.
