Description

Technical Field

[0001] The utility model belongs to the technical field of reaction equipment, in particular to a reaction device for producing tetrachloropyridine. Background Art

[0002] Tetrachloropyridine is an important component in the production of new pesticides and pharmaceutical products. In existing production processes, tetrachloropyridine is mostly produced by reacting dichloropyridine with chlorine. This process involves introducing dichloropyridine into a reactor, followed by chlorine. To enhance the rapid reaction between chlorine and the raw materials, existing reaction devices incorporate a drive assembly to rotate a stirring paddle, thereby accelerating contact between the chlorine and the raw materials and the reaction rate. While this can increase the reaction speed of the device to a certain extent, the reactor remains sealed, making subsequent cleaning of the reactor time-consuming and labor-intensive.

[0003] A search revealed a Chinese patent document (grant publication number CN211255773U) describing a reaction apparatus for producing 2,3,5,6-tetrachloropyridine. The apparatus comprises a reactor equipped with a pyridine inlet tube and a chlorine inlet tube, a stirring device driven by a power mechanism, a gas phase exhaust tube connected to a condenser, and a synergistic reactor located between the reactor and the condenser. The synergistic reactor comprises a reactor body, a glass sleeve inserted into the reactor body, and the glass sleeve separates the inner cavity of the reactor body into a reaction chamber and a heat source chamber. The upper surface of the reactor body is connected to a terminal block, and the reactor body is equipped with multiple sets of light sources located in parallel in the heat source chamber. While this patent can increase the reaction speed of the apparatus to a certain extent, the reactor is sealed, making subsequent cleaning of the reactor more time-consuming and labor-intensive.

The servo motor 15 is started to drive the installation box 5 to rotate, so that the second sealing cover 11 and the processing component 3 are adjusted in position. After the adjustment is completed, the drive motor 6 is started to drive the second sealing cover 11 to descend, and the stepping motor 10 is started to drive the cleaning brush 12 to rotate, thereby achieving the cleaning effect. When the reaction cylinder 1 needs to be moved, the first screw rod 31 is driven to rotate by rotating the adjusting wheel 44, so that the moving wheel 48 is moved out of the installation box 42, making the device easy to move.
