Description

Technical Field

[0001] The utility model belongs to the field of chemical equipment, and in particular relates to a high-efficiency mixing reactor. Background Art

[0002] The statements in this section are merely intended to provide background information related to the technical solution of the present application to aid understanding, and they do not necessarily constitute prior art with respect to the technical solution of the present application.

[0003] During reactor operation, a certain reaction temperature must be maintained. This temperature is typically controlled by introducing a cooling or heating medium into the reactor jacket. When stirring the reactor, centrifugal force causes the material to form a vortex at the center of the stirring shaft and rotate along the reactor wall, resulting in poor mixing. Simultaneously, the liquid level rises, exceeding the maximum level of the cooling jacket, affecting refrigeration or heat exchange efficiency.

[0004] In the prior art, a baffle is provided on the inner side wall of the kettle body in Chinese patent CN219784444U, and the baffle is installed on the inner side wall of the kettle body through a support rod. The gap between the kettle body and the baffle is used to reduce the influence of the stirring vortex on the stirring effect. The gap of this structure is narrow and relatively concentrated, and the effect of reducing the vortex is concentrated near the wall of the kettle body, which is not uniform enough; a triangular guide groove is provided on the inner wall of the kettle body in Chinese patent CN206996579U to divide and evacuate the fluid, and the baffle can enhance the turbulence of the material in the kettle body and increase the probability of collision, but there is also a problem that the effect is concentrated on the wall of the kettle body; Chinese patent CN206996579U has a transverse baffle and a side baffle installed on the upper part of the rotating shaft, which can solve the problem of material splashing, but the baffle is installed on the rotating shaft and moves with the rotating shaft. The process is not stable and cannot drive the mixing of materials outside the baffle. Utility Model Content

[0005] In order to improve the mixing effect of materials in the reactor and avoid the liquid level rising due to stirring and rotation, the utility model provides a high-efficiency mixing reactor:

[0006] A high-efficiency mixing reactor comprises a reactor body and an agitator. The inner wall of the reactor body is provided with a transverse baffle horizontally and a longitudinal baffle vertically. The transverse baffles and the longitudinal baffles are alternately distributed along the longitudinal direction, and the transverse baffle is the topmost. The transverse baffle is in the shape of a ring, and the width of the ring is 0.3-0.5 times the radius of the reactor body. The longitudinal baffle is in the shape of a "T" rotated 90°, and the short side of the "T" rotated 90° is vertically connected to the inner wall of the reactor body. A plurality of circular holes are opened on the longitudinal baffle, and the aperture range of the circular holes is Φ30-100mm.

[0007] Furthermore, the outer wall of the kettle is provided with a heating or cooling jacket.

[0008] Furthermore, each longitudinal baffle arranged in the longitudinal direction is regarded as a group, and the inner wall of the kettle body is provided with at least four groups of longitudinal baffles that are symmetrical in pairs.

[0009] Compared with the prior art, the beneficial technical effects of the present invention are as follows: the present invention installs a transverse annular baffle on the inner wall of the reactor to limit the up and down fluctuations of the material in the reactor, thereby enhancing the refrigeration or heat exchange effect, and the structure is relatively stable when installed on the inner wall of the reactor without affecting the stirring; in addition, a longitudinal baffle is installed on the inner wall to prevent the logistics from rotating uniformly along the reactor wall, and the transverse "T"-shaped structure protrudes a larger area toward the center of the reactor, which can fully collide and mix the materials in the reactor, and is not limited to the part close to the inner wall, and a plurality of circular holes are provided on the longitudinal baffle to increase the turbulent effect and further improve the mixing degree of the reaction materials.

[0013] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the following is a detailed description of a high-efficiency mixing reactor of the present invention in conjunction with an embodiment. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0014] In one embodiment, a mixing reactor comprises a reactor body 1, a heating or cooling jacket 2, an agitator 3, transverse baffles 4, and longitudinal baffles 6. The agitator 3 is tightly fitted with the reactor body 2, and the transverse baffles 4 and longitudinal baffles 6 are mounted on the inner wall of the reactor body 1. The top layer is a circular transverse baffle 4 with a width 0.3-0.5 times the inner radius of the reactor body 1. The next layer is four longitudinal baffles 6. The next layer is a transverse baffle 4 with the same structure as the top layer. The bottom layer is four longitudinal baffles 6. The longitudinal baffles 6 all have the same structure, forming a "T-shape" rotated 90°, with the short sides vertically fixed to the inner wall of the reactor body 1. The surface is provided with multiple circular holes 5 with an aperture of 30-100 mm, which can be the same or different. The transverse baffles 4 can effectively prevent the problem of the liquid level in the reactor rising due to the action of centrifugal force, thereby enhancing the refrigeration or heat exchange effect. The longitudinal baffle 6 is installed vertically along the inner wall of the kettle body 1 to enhance the mixing effect of the material and prevent the material from rotating uniformly along the kettle wall. The "T-shaped" structure of the longitudinal baffle 6 and the multiple circular holes 5 opened on the surface can increase the turbulent effect of the material and further enhance the mixing of the material.

[0015] When using the hybrid reactor, the cold / hot medium is first introduced into the jacket 2, and then the reaction materials are added to the reactor. The agitator 3 is turned on. Under the centrifugal force of the agitator 3, the materials rotate along the inner wall of the reactor body 1. Under the action of the longitudinal baffle 6, the material flow direction changes frequently, enhancing the mixing effect. The transverse baffle 4 limits the upward and downward fluctuation of the material, preventing the material liquid level from exceeding the position of the cold and hot medium jacket 2, thereby enhancing the heat exchange effect.
