The reaction kettle is composed of a kettle body, a kettle cover, a jacket, a stirrer, a transmission device, a shaft sealing device and a bracket. When the height and diameter of the stirring device are large, multi-layer stirring blades can be used, or they can be arbitrarily selected according to user requirements. A jacket is provided on the outside of the reactor wall, or a heat exchange surface is provided in the vessel, and heat exchange can also be performed through external circulation. The support base includes a support type or an ear type support base. If the rotation speed exceeds 160 revolutions, it should be Use a gear reducer. The number of holes, specifications or other requirements can be designed and manufactured according to user requirements.

1. Packing seal is usually used under normal pressure or low pressure, and the pressure is usually less than 2 kg.

2. Under general medium pressure or vacuum conditions, mechanical seals are used, and the general pressure is negative pressure or 4 kg.

3. The electromagnetic seal will be used under high pressure or high volatile medium, usually the pressure exceeds 14 kg. In addition to the use of water-cooled magnetic seals, other sealing forms will increase the cooling water jacket by more than 120 degrees.

The reactor is a kind of reaction equipment, and care must be taken during the operation, otherwise it will be damaged due to various reasons, forcing the production to stop. There are many aspects to the operation of the reactor.

First, the reactor must be operated in strict accordance with the rules and regulations.

Secondly, before operation, please check carefully whether there is an abnormality. During normal operation, do not open the upper cover and touch the wiring terminals on the board to avoid electric shock, and do not operate under pressure; when performing a pressure test with nitrogen, carefully observe the pressure. When the change of the meter reaches the test pressure, immediately close the nitrogen valve switch; the heating speed should not be too fast, and the pressurization should be carried out slowly, especially the stirring speed, which can only allow a slow rise.

Finally, when heating the reactor body to a higher temperature, do not touch the pot body to avoid injury; the temperature should be lowered after the experiment. Rapid cooling is not allowed to prevent damage due to temperature difference and excessive pressure. At the same time, unplug the power supply in time.

At the same time, pay attention to maintenance after using the reactor to make the autoclave have a better service life.
