Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for reactors, specifically a multi-directional liquid jet mixing device for reactors. Background Technology

[0002] Reactors are commonly used reaction equipment in industries such as chemical, pharmaceutical, and food processing, primarily for realizing various physical and chemical reactions. During the reaction process, it is usually necessary to thoroughly mix the various liquid raw materials within the reactor to ensure the uniformity and completeness of the reaction, thereby improving the quality and yield of the product.

[0003] Currently, most traditional reactors use a single stirring paddle for liquid mixing. This method has significant drawbacks: firstly, the stirring range of the paddle is limited, easily creating dead zones within the reactor, resulting in some areas of liquid not being fully mixed and affecting the uniformity of the reaction; secondly, for liquids with high viscosity, the stirring efficiency of the paddle is low, requiring a large amount of energy to achieve effective mixing, which not only increases production costs but may also cause the liquid temperature to rise due to prolonged stirring, affecting the normal progress of the reaction.

[0004] To address the aforementioned issues, some reactors employ jet mixing to assist stirring. However, most existing jet mixing devices can only achieve unidirectional jetting, with a fixed jet direction that cannot be adjusted according to the actual conditions of the liquid within the reactor. This results in limited jet mixing effectiveness and makes it difficult to achieve comprehensive and uniform mixing of the liquid. Therefore, it is necessary to design a multi-directional liquid jet mixing device for reactors. Utility Model Content

[0026] Please see Figures 1-4 This utility model discloses a multi-directional liquid jet mixing device for a reaction vessel, including a reaction vessel body 1;

[0027] The bottom of the reactor body 1 is equipped with a main inlet pipe 2, which is made of high-strength seamless steel pipe. The pipe diameter is determined according to the volume of the reactor body 1 and the expected liquid delivery volume, generally 50-100mm. One end of the main inlet pipe 2 extends to the outside of the reactor body 1 and is connected to an inlet pump 3. The inlet pump 3 is a corrosion-resistant centrifugal pump, which can adjust the delivery pressure and flow rate according to the actual mixing requirements to provide stable power for liquid delivery. The other end of the main inlet pipe 2 extends into the inside of the reactor body 1 and is fixedly connected to a distribution pipe assembly. The connection between the main inlet pipe 2 and the distribution pipe assembly is sealed by welding to ensure that the liquid does not leak.

[0028] In this invention, the diversion pipe assembly includes a main diversion pipe 4 and several branch diversion pipes 5. The diameter of the main diversion pipe 4 is the same as that of the main inlet pipe 2, ensuring that the liquid can be evenly distributed to each branch diversion pipe 5. The main diversion pipe 4 is coaxially arranged with the main inlet pipe 2. The several branch diversion pipes 5 are evenly distributed radially around the main diversion pipe, with equal included angles between adjacent branch diversion pipes 5. The branch diversion pipes 5 are internally connected to the main diversion pipe 4. The branch diversion pipes 5 and the main diversion pipe 4 are manufactured using an integral molding process to avoid liquid leakage due to connection gaps. Multiple jetting mechanisms are evenly distributed on each branch diversion pipe 5.

[0029] The jetting mechanism includes a jetting tube 6 and an angle adjusting component 7. The jetting tube 6 is made of stainless steel. One end of the jetting tube 6 is rotatably connected to the branch pipe 5 through the angle adjusting component 7, and the jetting tube 6 is internally connected to the branch pipe 5. The other end of the jetting tube 6 is provided with a nozzle 8. A flow regulating valve is provided on the jetting tube 6 near the nozzle 8. The flow regulating valve is a manually adjustable ball valve, which can accurately control the liquid flow rate through the jetting tube 6. The operator can flexibly adjust it according to the mixing of the liquid during the reaction process.

[0030] like Figure 2 , Figure 3As shown, the angle adjusting component 7 includes a fixed sleeve 9 and a rotating sleeve 10. The fixed sleeve 9 is made of stainless steel, and its inner diameter is the same as the outer diameter of the branch diversion pipe 5. It is fixedly sleeved on the branch diversion pipe 5 by welding. The side wall of the fixed sleeve 9 has a connecting hole that communicates with the inside of the branch diversion pipe 5. The diameter of the connecting hole is the same as the inner diameter of the jet pipe 6. The rotating sleeve 10 is also made of stainless steel. It is sleeved on the outside of the fixed sleeve 9 and rotates in cooperation with the fixed sleeve 9. The rotating sleeve 10 can rotate 360° around the axis of the fixed sleeve 9. The jet pipe 6 is fixedly connected to the side wall of the rotating sleeve 10 by welding. The interior of the rotating sleeve 10 is connected to the connecting hole, ensuring that liquid can enter the jet pipe 6 from the branch pipe 5 through the connecting hole and the interior of the rotating sleeve 10 in sequence. The outer wall of the fixed sleeve 9 is provided with an annular groove 11, and the inner wall of the rotating sleeve 10 is provided with an annular protrusion 12 that matches the annular groove 11. The width and depth of the annular protrusion 12 are the same as the width and depth of the annular groove 11, respectively. The annular protrusion 12 is engaged in the annular groove 11. This structure can restrict the axial movement of the rotating sleeve 10 on the fixed sleeve 9, ensure the stability of the rotation process, and prevent liquid leakage from the fitting gap between the fixed sleeve 9 and the rotating sleeve 10.

[0031] like Figure 4 As shown, the nozzle 8 is a conical nozzle made of stainless steel with a cone angle of 30°-60°, which can expand the jet range of the liquid. The outlet end of the nozzle 8 is provided with several flow-dividing teeth 13, which are made by integral molding process with the nozzle 8. The flow-dividing teeth 13 are evenly distributed in a ring around the axis of the nozzle, and the included angle between adjacent flow-dividing teeth 13 is equal. The flow-dividing teeth 13 can divide the liquid ejected from the nozzle 8 into multiple fine liquid streams, enhance the collision and mixing effect of the liquid stream with the surrounding liquid, and further improve the mixing uniformity.

[0032] In this invention, several flow-disrupting plates 14 are provided on the inner wall of the reactor body 1. The flow-disrupting plates 14 are made of stainless steel. Several flow-disrupting plates 14 are distributed at intervals along the height direction of the reactor body 1, with a spacing of 30-50cm. The flow-disrupting plates 14 are set at an angle of 45°-60° with the inner wall of the reactor body 1. The flow-disrupting plates 14 are fixedly connected to the inner wall of the reactor body 1 by welding. When the liquid in the reactor flows under the action of jet and stirring, the flow-disrupting plates 14 can break the regular flow trajectory of the liquid, form a turbulent flow field, reduce the dead angle of stirring, and improve the mixing efficiency of the liquid.

[0033] In addition, in this utility model, a stirring motor 15 is provided on the top of the reactor body 1. The stirring motor 15 is a three-phase asynchronous motor. The output shaft of the stirring motor 15 extends into the interior of the reactor body 1 and is connected to a stirring shaft 16 via a coupling. The stirring shaft 16 is made of stainless steel and has several stirring blades. The stirring blades are located above the diversion pipe assembly, and the spacing between adjacent stirring blades is 40-60cm. The stirring blades are spiral stirring blades 17, which can generate axial and radial forces on the liquid during rotation, promoting the vertical circulation and radial diffusion of the liquid. Furthermore, several through holes 18 are provided on the surface of the stirring blades. The through holes 18 can reduce the liquid resistance encountered by the stirring blades during rotation, reduce the energy consumption of the stirring motor 15, and allow some liquid to pass through the through holes 18, forming a small-scale turbulence and enhancing the mixing effect.

[0034] Working Principle: In actual operation, the liquid raw materials to be mixed are first added to the reactor body 1 according to the reaction requirements. The liquid inlet pump 3 is started, and the liquid inlet pump 3 delivers the external liquid to the main distribution pipe 4 through the main liquid inlet pipe 2. The main distribution pipe 4 evenly distributes the liquid to each branch distribution pipe 5. According to the actual situation such as the viscosity of the liquid in the reactor and the reaction stage, the operator adjusts the jet angle of the jet pipe 6 through the angle adjustment component 7, rotates the rotating sleeve 10, and drives the jet pipe 6 to rotate around the fixed sleeve 9 until the jet direction meets the mixing requirements. At the same time, the liquid flow rate of each jet pipe 6 is adjusted through the flow regulating valve. The liquid enters the jet pipe 6 from the branch distribution pipe 5 and is divided by the nozzle 8. After being divided by the tooth 13, the liquid is sprayed into the liquid inside the reactor body 1 in the form of multiple fine liquid streams, causing impact disturbance to the liquid. Then, the stirring motor 15 is started, which drives the stirring shaft 16 and the spiral stirring blades 17 to rotate. The spiral stirring blades 17 stir the liquid axially and radially, promoting the vertical circulation of the liquid. The through holes 18 on the surface of the blades reduce stirring resistance and form local turbulence. Under the impact of the jet and the stirring action, the liquid interacts with the baffles 14 on the inner wall of the reactor, breaking the regular flow field and forming an all-round turbulent flow state, which greatly increases the degree of disturbance of the liquid, accelerates the mixing speed, ensures the mixing uniformity, and thus improves the reaction efficiency and product quality.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
