Embodiment 2

[0012] Embodiment 2 The working process of the electrical automatic control system of a pneumatic conveying system for soybeans:

[0013] The industrial control computer or DCS system 2 uses the PLC programmable control system 1 to measure the data through the load cell 19 and the mass flow meter 20 according to the material-gas ratio. The compressed air with the set pressure value of the pressure valve 5 discharges the soybeans added from the material hopper into the outlet of the warehouse pump through the pneumatic discharge valve 10, and transports them to the material pipeline. According to the process and production needs, the soybeans are distributed into the warehouse by the pneumatic switching valve 12 , The high-level material level gauge 13 and the low-level material level gauge 15 are installed on the silo for controlling the material level of the silo. When the soybeans are transported to the middle section of the pipeline, the pulse pneumatic valve 18 starts to...

Abstract

The invention relates to an automatic electric control system of a soybean pneumatic transportation system. The automatic electric control system comprises a PLC system 1, an industrial computer or DCS system 2, an air compressor and refrigeration dryer motor 3, an electric contact pressure gauge 4, a pressure regulating valve 5, a pneumatic exhaust valve 6, a pressure transmitter 7, a feeding valve 8, a pneumatic pre-closing valve 9, a pneumatic discharging valve 10, a high level meter 11, a pneumatic converter valve 12, a high level meter 13, a pressure relief valve 14, a low level meter 15, a pneumatic plug valve 16, a signal transmission cable 17, a pulse pneumatic knife-edge valve 18, a weighing sensor 19 and a mass and flow meter 20. The automatic electric control system is characterized in that the automatic electric control system is controlled by the PLC system 1 integrally, the material-air ratio ranges from 42 to 45, and the system adjusts pipeline equipment according to the material-air ratio. The automatic electric control system has the advantages that the control process is relative to relevant component actions, and actions are executed automatically; the material-air ratio optimization control is guaranteed during transportation, the compressed air is saved, and the operation cost is reduced.
