Optionally, a handle is arranged on the upper surface of the rotating plate.

Through adopting above-mentioned technical scheme, when needs add reduction reaction liquid in toward the dropwise add jar, through handle upset rotor plate convenient and fast more.

Optionally, the lower end of the dripping tank is provided with a support frame for supporting the dripping tank, and the support frame is higher than the reaction kettle.

Through adopting above-mentioned technical scheme, the support frame supports the dropwise add jar and guarantees that the dropwise add jar is fixed more stable, and the height of dropwise add jar is higher than reation kettle, and the reduction reaction liquid in the dropwise add jar can flow to reation kettle automatically when opening control valve and balanced valve for the dropwise add is more smooth and easy.

In summary, the present application includes at least one of the following beneficial technical effects:

1. a pressure balance pipe is added between the dripping tank and the reaction kettle, so that the air pressure in the reaction kettle and the dripping tank is balanced, and the reduction reaction liquid is more smoothly dripped into the reaction kettle;

2. the flow meter is arranged on the dropping pipe, so that the dropping amount of the reduction reaction liquid can be observed in real time, and a worker can close the control valve in time according to requirements;

3. the sealed effect that can improve the dropwise add jar of sealed pad, the joint is detained can with the stable inseparable jar body lock with the dropwise add jar of rotor plate.
