FZC series overview rotor rotor scale powder powder feeding system is in the digestion and absorption of foreign advanced powder feeding technology, based on the development of applied powder feed continuous metering equipment). Rotor powder feeding system consists of: screw gate valve pre-feeder (FRC powder feeder, star-shaped feeder, screw feeder, valves group) rotor scale soft connection control system components. Rotor scale structure and principles: balance the rotor structure weighing scales with material weight, balance the body by the motor, impeller rotor and disc composed of both exports and imports with a soft connection, does not affect the balance of the body by the force of rotation, designed to ensure that when both sides of the balance of the balance body. In the powder supply process, due to the rotation of the impeller, the material in the inlet to the discharge port of the semicircle weeks uniform flow, load sensors to precisely half circle to feel the weight of the powder, the weight of the signal and the rotor speed signal in the microcomputer After calculation within the flow signal was passed after comparison with the set value to control the amount of frequency conversion motor (including pre-feeder frequency conversion motor), adjust the rotor scale and pre-feeder speed can be adjusted powder traffic. FZC series Powder rotor scale features: powder feeding system uses a multi-layer seal structure to ensure continuous delivery of powder, uniform and stable feeding, not knot arch, jets, congestion and other high precision feeding. As a result of the flexible seal, to solve the problem jet, wear and temperature changes arising. Rotor scale structure using scales, balance scales on both sides of the body, the sensor detects only the weight of the powder. Expected out and pivot on the same axis, the impact is not material impact on the balance balance. Well controlled performance, a wide range of flow regulation, high accuracy. Simple structure, compact, sealed, easy installation and maintenance. Using Plc + hmi control system, powerful measurement error: ≤ ± 0.5% control accuracy: ≤ ± 0.1% feeder capacity: 3 ~ 100m3 / h capacity: Model Production Capacity (m3 / h) FZC-1 10 FZC-2 30 FZC-3 60 FZC-4 100 system operating conditions: System Power: ≤ 22kw Power: 380 / 220V ± 15% 50hz ± 2% Ambient temperature: -20 ℃ -50 ℃ Relative humidity: ≤ 85% Material: Powder material (coal, raw material powder, fly ash, etc.)
