Questions about continuous solid feeding

A pressure difference buffer bin is added between the sealed automatic feeding equipment of the reactor and the reactor. When the reactor is unloaded, the material enters the buffer bin and then enters the reactor. The buffer bin is composed of two switching valves. This time, the material is switched into the bin to ensure that the pressure inside the reactor will not leak. The reactor is sealed and automatically fed. The pipeline for transporting materials is connected to the workshop ground to conduct static electricity away from the material.； First, suck it into the equipment and then discharge it into the reaction kettle. While unloading, perform nitrogen backflush to increase the inert gas in the kettle to prevent accidents. The sealed automatic feeding equipment of the reactor replaces the manual feeding of powders and solid particles into the reactor. The equipment and the reactor are tightly connected and softly connected. Dust will not be generated when feeding, which increases the material utilization rate. The equipment and the reactor are tightly connected to prevent organic solvents from spilling out of the reactor during feeding. The feeding time is fast and efficient, and the labor intensity of employees is reduced. The equipment is controlled by PLC, and the program is written according to the actual production needs of the customer. It can be connected to the workshop DCS control system to monitor the running status and start and stop of the equipment. It has been put into use in the production of the pesticide raw material thiamethoxam, replacing the manual input of oxadiazine and ultrafine potassium carbonate into the reactor.
