[0001] The utility model relates to the technical field of isophthaloyl chloride processing, in particular to a continuous distillation device for compound production. Background Technique

[0002] Isophthaloyl chloride is an important organic chemical raw material and has a wide range of applications in industrial materials, electrical insulation materials, protective clothing, interior decoration materials, etc. Isophthaloyl chloride can be obtained by distillation.

[0003] When the existing distillation device is performing distillation work, most of them make the chemical substances layer by static settlement, but this will make it difficult for the compound to be fully and evenly heated, affecting the distillation efficiency. And after the distillation is completed, there are usually some compounds remaining in the distillation device. However, the cover of the distillation device is usually integrally arranged on the distillation device and is difficult to open, which is not conducive to cleaning the inside of the distillation device and is not conducive to the subsequent distillation work. For this reason, we designed a continuous distillation device for compound production to solve the above problems. Content of the Utility Model

Through the first distillation tank and the second distillation tank, the isophthaloyl chloride in the compound can be fully distilled out. And during the distillation process, the two rotating rods can rotate synchronously, so that the stirring blades rotate to stir the compound, enabling the compound to be fully and evenly heated, ensuring the distillation efficiency. After the distillation is completed, controlling the cover to move upward can open the first distillation tank and the second distillation tank, facilitating the cleaning of their interiors, and the operation is simple.
