The blowing hood 21 can blow gas onto the sliding section of the tilted addition tube 2. The gas blowing position corresponds to the sliding position, thus the catalyst inside the tilted addition tube 2 is added according to the gas blowing. The feeding range can be effectively changed according to the size of the pneumatic force, which facilitates the uniform addition of catalyst for processing. The outer end of the blowing hood 21 is connected to the gas supply pipe 22, which can receive the gas supplied by the gas supply pipe 22.

The screw feeding rod inside the screw feeding pipe 4 can effectively screw-feed the catalyst during circumferential rotation. A feed pipe 42 is fixedly connected through the upper right inlet of the screw feeding pipe 4, through which the screw feeding pipe 4 receives the catalyst. A discharge pipe 43 is fixedly connected through the lower left outlet of the screw feeding pipe 4, through which the catalyst inside the screw feeding pipe 4 can be discharged. The lower end of the discharge pipe 43 is secured by screws. The device is equipped with an inclined addition pipe 2 for m-chlorobenzoyl chloride catalyst. The discharge pipe 43 can transport the catalyst into the inclined addition pipe 2 for m-chlorobenzoyl chloride catalyst.

The spiral feed rod motor 41 can be operated and controlled by the control box.

[0034] Working principle: The pneumatic dispersion and addition mechanism can pneumatically disperse the received m-chlorobenzoyl chloride synthesis catalyst into the m-chlorobenzoyl chloride synthesis reactor 1. The overall material dispersion range can be adjusted according to the magnitude of the pneumatic force, which facilitates uniform addition. The screw feeding mechanism can screw-feed the catalyst into the pneumatic dispersion and addition mechanism. The screw feeding mechanism can be suspended and pulled by the adjustable suspension mechanism to stabilize the screw feeding. The screw feeding mechanism can receive the material falling from the m-chlorobenzoyl chloride catalyst addition mechanism for screw feeding. The gas pipe limiting mechanism can limit and suspend the screw feeding mechanism at the lower end.
