Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a novel high-efficiency continuous reaction vessel. Background Technology

[0002] Reactors, commonly used liquid-phase reaction devices in industries such as chemical, pharmaceutical, and food processing, are widely applied in various chemical reaction processes. Their internal stirring and mixing performance directly affects the efficiency and quality of the reaction. In existing technologies, continuous reaction vessels typically employ a fixed drive unit to rotate the stirring shaft, using impellers or blades to agitate the reaction liquid, thereby promoting material mixing and reaction. A typical structure usually includes the reaction vessel body, stirring components (such as rotating blades), an electric drive motor, and liquid inlet / outlet devices.

[0003] However, existing continuous reactors generally suffer from the following technical problems and shortcomings:

[0004] Limited stirring coverage: Traditional stirring structures generally rely solely on impeller rotation to create localized vortex flow inside the vessel, failing to form effective liquid circulation in the vertical or axial direction, resulting in insufficient mixing of the upper and lower liquid layers and low mixing efficiency.

[0005] Weak convection disturbance effect: Although some reactors are equipped with flow guiding structures or guide pipes, due to the lack of effective liquid flow dispersion structures, short-circuit flow or dead zone still exists in the process of liquid introduction and discharge, and effective convection disturbance cannot be achieved.

[0006] In view of this, we will study and improve the existing problems to provide a new type of high-efficiency continuous reactor to solve the current problems. The aim is to solve the problems and improve the practical value through this technology. Utility Model Content

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a novel high-efficiency continuous reaction vessel.

[0030] Combination Figures 1-4 As shown, this utility model provides a novel high-efficiency continuous reactor, comprising:

[0031] Reactor body 100: This is the main container for holding the reaction liquid. It has a cylindrical structure and an outer wall equipped with a water bath coil 110 for temperature control. The coil is spirally wound around the outer circumference of the reactor body 100 to circulate heat or cold medium to regulate the reaction temperature. The reactor body 100 is made entirely of corrosion-resistant metal material, with a stable structure and good sealing performance.

[0032] Water bath coil 110: Fixed to the outer wall surface of the reactor body 100 and arranged in a spiral pattern along its outer circumference, used to achieve temperature control function, suitable for heating or cooling processes of chemical reactions.

[0033] The reciprocating drive assembly 200 includes a support 210 mounted on top of the reactor body 100 and a drive rod 220 disposed on top of the support 210. The drive rod 220 adopts an electric push rod structure, and its output end is connected to the top structure of the mixing assembly 300. This assembly is used to drive the mixing assembly 300 to move up and down along the axial direction of the reactor body 100, thereby promoting the three-dimensional flow and stirring of the reaction liquid.

[0034] Support frame 210: A frame component that supports the drive structure and is fixedly installed on the top surface of the reactor body 100;

[0035] Drive rod 220: Located on the support frame 210, it is an electric push rod structure that can drive the connected structure to reciprocate in the vertical direction;

[0036] Vertical rod 221: Connected to the output end of drive rod 220, used to transmit reciprocating driving force to the top of hybrid assembly 300.

[0037] Mixing component 300: Located inside the reactor body 100, it mainly includes a swirl tank 310, a flow guide chamber 320, a drive motor 330 and its driven stirring blades 340, etc., and is used to achieve mixing and stirring of the reaction liquid.

[0038] Swirl 310: The outer shell of the mixing assembly, which contains the liquid flow and the movement of the swirling blades;

[0039] Flow guiding chamber 320: Located inside the vortex tank 310, it serves as a space for guiding and disturbing liquid flow, and a dispersion cylinder 321 is fixedly installed at its top.

[0040] Dispersion cylinder 321: Used for dispersing and discharging liquid flow. Its surface is provided with multiple through holes. The through holes are evenly arranged, which can make the liquid evenly dispersed and discharged under the stirring of the blades, forming an axial flow path.

[0041] Drive motor 330: mounted on the top surface of dispersion cylinder 321, with its output end passing through guide chamber 320 and connected to stirring blade 340;

[0042] Stirring blade 340: It is a paddle structure, in the shape of a propeller blade, and is fixedly installed on the output shaft of the drive motor 330. During the rotation of the blade, it can drive the reaction liquid to form an upward flow along the axial direction, thereby improving the liquid convection mixing efficiency.

[0043] Liquid inlet plate 311: Installed on the bottom surface of the swirl tank 310, the plate surface is provided with several liquid inlet grid holes and liquid inlet holes evenly distributed along the circumference, used to introduce the reaction liquid into the mixing component from the bottom, and to achieve sufficient liquid disturbance in conjunction with the stirring blade 340.

[0044] Structural synergy principle and effect support: Through the lifting and lowering motion of the reciprocating drive component 200, combined with the axial driving force formed by the stirring blade 340, the three-dimensional stirring of the liquid inside the reactor body 100 is realized; at the same time, after the liquid is introduced through the liquid inlet plate 311, it is disturbed by the stirring blade 340 and discharged through the through hole of the dispersion cylinder 321, forming a strong convection mixing effect, which significantly improves the mixing efficiency and reaction uniformity.

[0045] Sealing and anti-corrosion structure: To ensure the long-term stable operation of the drive motor 330, a sealing component is provided at the end of its output shaft, which can effectively prevent the reaction liquid from seeping into the motor. In addition, the motor surface is coated with an anti-corrosion layer to improve the overall durability of the equipment.

[0046] Working principle and usage process of this utility model:

[0047] This utility model provides a novel high-efficiency continuous reaction vessel, which mainly achieves three-dimensional mixing and strong convection stirring of the reaction liquid through the coordinated work of the reciprocating drive component 200 and the mixing component 300. Its core principles include the following aspects:

[0048] The drive rod 220 drives the mixing component 300 to reciprocate vertically along the reactor body 100, so that the entire stirring component can disturb the liquid in the reactor in the vertical direction during operation, break the laminar flow structure of the liquid, and enhance the stirring coverage of each area of ​​the reactor body.

[0049] The drive motor 330 drives the stirring blade 340 to rotate at high speed. The stirring blade is shaped like a propeller blade. During the rotation, it can transport the liquid at the bottom upward, generating obvious axial flow, thus forming a bottom-up circulating mixing flow.

[0050] The reaction liquid is introduced from the bottom of the inlet plate 311, which is equipped with multiple inlet holes and grid holes to ensure uniform liquid distribution. After being disturbed by the swirl vanes, the liquid is dispersed and discharged through the surface through holes in the upper part of the dispersion cylinder 321, further increasing the degree of fluid disturbance and enhancing the uniform mixing of the reaction liquid.

[0051] The externally installed water bath coil 110 is spirally wound around the reactor body 100. Through the circulation of cooling or heating media, the temperature of the entire reaction process can be controlled in real time, ensuring the stability of the reaction conditions.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
