Description

Technical Field

[0001] The utility model relates to the technical field of tebuconazole production, in particular to a dissolution reaction kettle for preparing tebuconazole. Background Art

[0002] Tebuconazole is a highly effective, broad-spectrum, systemic triazole fungicide with important application value in the agricultural field. In the preparation process of tebuconazole, the dissolution reaction step is crucial.

[0003] Traditional dissolution reactors used in the preparation of tebuconazole suffer from uneven stirring, preventing sufficient contact and reaction between raw materials. This presents numerous challenges in tebuconazole production. For example, existing reactors with a single stirring blade have limited stirring area, preventing some raw materials from reacting at the appropriate time and under the appropriate conditions. This not only reduces reaction efficiency but also hinders the progress of the reaction.

[0004] Furthermore, some raw materials tend to clump together in the reactor, making them difficult to fully dissolve and pulverize. For example, certain viscous or large-particle raw materials tend to clump together under conventional stirring conditions, making them difficult to disperse in the solvent, significantly impacting the dissolution effect. Furthermore, existing reactors also lack sufficient pulverization, preventing these raw materials from fully functioning in the reaction. This further reduces the efficiency of the dissolution reaction and the yield of tebuconazole, while also impacting product quality.

[0005] In summary, the production of tebuconazole is seriously restricted due to the problems of uneven stirring in common reactors and difficulty in fully dissolving and crushing raw material nodules, which affects the yield and quality of the product. Therefore, the utility model provides a dissolution reactor for preparing tebuconazole that can achieve uniform stirring, effective crushing and sufficient dissolution of raw materials. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a dissolution reaction kettle for preparing tebuconazole.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A dissolution reactor for preparing tebuconazole comprises a reactor body for performing a dissolution reaction on raw materials for preparing tebuconazole, and a reactor cover movably mounted on the top of the reactor body via mounting bolts; a motor is fixedly mounted on the top center of the reactor cover via a mounting bracket; an output end of the motor rotates through the inside of the mounting bracket and is fixedly connected to a transmission shaft; a bottom end of the transmission shaft rotates through the reactor body and is fixedly connected to a rotating shaft; a U-shaped stirring paddle is fixedly mounted on the bottom of the rotating shaft;

[0009] A spiral stirring blade for spirally stirring the tebuconazole raw material is fixedly provided on the rotating shaft above the inner side of the U-shaped stirring paddle, and a plurality of crushing protrusions for dispersing and crushing the tebuconazole raw material are fixedly provided on the surface of the spiral stirring blade; a plurality of stirring rods are also fixedly connected to the rotating shaft, and the stirring rods and the spiral stirring blades are staggered;

[0010] Both sides of the U-shaped stirring paddle are provided with a plurality of crushing blades for crushing the tebuconazole raw material. A plurality of triangular crushing knife tips are fixedly provided on the circumferential inner wall of the reactor body, and the crushing blades are adapted to the triangular crushing knife tips.

[0011] Furthermore, stirring shrapnel for oscillating and stirring the tebuconazole raw material solution is fixedly connected to both sides of the bottom of the U-shaped stirring paddle; the spiral stirring blade specifically outputs a spiral motion trajectory from bottom to top.

[0012] Furthermore, adjustment components are provided on both sides of the U-shaped stirring paddle; the adjustment components include multiple mounting heads fixedly connected to both sides of the U-shaped stirring paddle, mounting holes are provided on the mounting heads and the crushing blades, and the crushing blades are fixed on the mounting heads by adjusting bolts.

[0013] Furthermore, a rotating bracket is fixedly provided on the inner wall of the bottom side of the reactor body, and the bottom end of the rotating shaft is rotatably mounted on the rotating bracket through a bearing.

[0014] Furthermore, a feed port is provided on the right side of the top of the kettle cover, and a discharge port is provided at the bottom of the reactor body; a pressure gauge and a sampling tube port are also provided on the left side of the top of the kettle cover.

[0015] Furthermore, a support frame is provided at the bottom of the reactor body; a controller is provided at the front of the reactor body, and the controller is electrically controlled and connected to the motor.

[0016] With the above structure, the beneficial effects achieved by the utility model are as follows:

[0017] 1. In the present invention, the motor drives the transmission shaft, the rotating shaft, the U-shaped stirring paddle, and the stirring rod to rotate, thereby rotating and stirring the raw materials for preparing tebuconazole; at the same time, the rotation of the U-shaped stirring paddle also drives the stirring shrapnel to rotate and vibrate, thereby further oscillating and mixing the raw materials;

[0018] 2. In the present invention, when the rotating shaft rotates, it also drives the spiral stirring blade to move in a spiral motion. Since the spiral stirring blade is specifically in a spiral output direction from bottom to top, the lower material in the inner cavity of the reactor body can be spirally transported from bottom to top, which is conducive to the full exchange and mixing of the lower raw materials with the upper raw materials, so that the raw materials between the upper and lower parts can fully contact and react, ensuring that the raw materials in different areas can fully participate in the reaction, which not only improves the efficiency of the dissolution reaction, but also improves the degree of the reaction;

[0019] 3. In the present invention, the U-shaped stirring paddle also drives the breaking blade to rotate when it rotates, thereby breaking the raw materials. The breaking blade also throws the raw materials around during the rotation and breaking. Under the action of centrifugal force, the thrown raw materials are further caused to collide with the triangular breaking blade tips on the inner wall of the reactor body. In this way, the triangular breaking blade tips can further play a role of collision and breaking, which can not only break up some raw materials with high viscosity or large particles, but also prevent the raw materials from easily agglomerating into agglomerates under conventional stirring conditions and becoming difficult to fully disperse in the solvent, thereby causing poor dissolution effect.

[0020] 4. In addition, an adjustment component is provided between the U-shaped stirring paddle and the crushing blade. By loosening and tightening the adjustment bolt, the angle of the crushing blade installed on the mounting head can be adjusted. The structure is simple and easy to adjust, which further improves the flexibility of crushing.

[0021] In summary, the dissolution reactor for preparing tebuconazole is not only convenient for rotating stirring, vibrating stirring and spiral stirring from bottom to top of the raw materials, so as to promote sufficient stirring and dissolution reaction of the raw materials between different regions; it can also crush and scatter the raw materials, so as to further promote the reaction rate of raw material dissolution, and solve the problems of uneven stirring and difficult full dissolution and crushing of raw materials in existing reactors. This is conducive to further improving the dissolution reaction efficiency, greatly ensuring the quality of the product, and is suitable for promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS
