Embodiment Construction
[0014] The invention includes two major parts: an automatic control system in a control room of a feed control device and a field device for feed control.
[0015] The electrical cabinet is equipped with a feeding frequency converter and its braking resistor, an air switch, an AB programmable controller and its output and input modules; the output module on the AB programmable controller controls the feeding speed and start and stop, through the communication module The DP bus controls the operation of the feeding frequency converter, and the input module on the AB programmable controller controls the feeding weighing sensor, the silo radar level gauge, and the digital value code analyzer respectively. Such as figure 1 shown.
[0016] The on-site device for feed control includes: feed weighing sensor, silo radar level gauge, and digital value code analyzer; Installed on the inner top to measure the real-time material level in the silo, the metal magnesium feeding is automati...
