Chlorination chemical reactor with multi-layer temperature controllable function

The invention relates to the technical field of chlorination reaction equipment, and discloses a chlorination chemical reactor with a multi-layer temperature controllable function, the chlorination chemical reactor with the multi-layer temperature controllable function comprises a reaction kettle, the reaction kettle is provided with a driving motor, the reaction kettle is provided with a through hole, and the through hole is communicated with the driving motor. An output shaft of the driving motor penetrates through the through hole, a first reciprocating lead screw is mounted on the output shaft, a moving block is mounted on the first reciprocating lead screw in a sliding manner, a temperature sensor is mounted on the moving block, and a plurality of heaters, starting heaters and the driving motor are mounted on the inner wall of the reaction kettle. The driving motor drives the moving block to longitudinally reciprocate through the first reciprocating lead screw, so that the temperature sensor can synchron
