AI Technical Summary
In existing red-based KD processing catalytic reactors, the stirring blades do not stir evenly, resulting in uneven heat distribution. This leads to low mixing efficiency of reactants, catalysts, and solvents, and catalysts are prone to deposition, thus affecting reaction efficiency.
A serpentine heating tube is connected to a turntable via a connecting rod. The rotation of the turntable drives the serpentine heating tube and the connecting rod to rotate, replacing the traditional stirring blades. Combined with a reciprocating motor-driven gear system, this achieves the rotation of the serpentine heating tube and the cleaning function of the scraper, ensuring uniform heat distribution and uniform material mixing.
It improves the mixing efficiency of reactants and catalysts and the uniformity of temperature distribution, prevents precipitation, and enhances production quality and work efficiency.

[0002] In the chemical industry, catalytic reactors are the core equipment for chemical reactions, especially in the processing of red-based KD (such as aniline, dichlorobenzene, etc.), where the design of the catalytic reactor is crucial to reaction efficiency and product quality.
[0003] Based on the above, the inventors have discovered the following problems: In the use of existing red-based KD processing catalytic reactors, the heating tubes of most devices are fixed around the stirring blades, which results in uneven stirring and uneven heat distribution, reducing the efficiency of thorough mixing of reactants, catalysts and solvents, and easily causing catalyst deposition, thereby affecting the reaction efficiency.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a catalytic reactor for red-based KD processing, in order to achieve a more practical value. Utility Model Content

A mounting groove is located at the bottom of the lid, and a turntable is movably mounted within the groove. A plurality of serpentine heating tubes are equidistantly mounted at the bottom of the turntable, extending into the reaction chamber. A cover is located at the bottom of the turntable, and a connecting rod is mounted at the center of the serpentine heating tubes. A scraper is mounted at the bottom of the connecting rod, with its bottom surface fitting against the bottom of the reaction chamber. A discharge pipe is installed at the bottom of the reactor body.
[0007] Furthermore, a gear one is installed on the top periphery of the turntable, the top of the turntable is rotatably connected to the mounting groove one via a coupling, the periphery of the turntable is rotatably connected to the mounting groove one via a hinge, the mounting groove one matches the turntable and the gear one, a mounting groove three is provided on one side of the mounting groove one, a gear two is rotatably installed in the mounting groove three via a rotating rod, and the gear two is connected to the gear one by tooth meshing.
[0008] Furthermore, a reciprocating motor is installed on the box cover, and the output end of the reciprocating motor is connected to the top of the second gear via a coupling.
[0009] Furthermore, a second mounting groove is provided between the turntable and the cover, and a heater is installed in the second mounting groove. The input ends of several serpentine heating tubes pass through the cover and are electrically connected to the heater.
