How to realize iron removal control for self-unloading iron separator rectifier equipment

The iron separator rectification equipment is a device specially designed and developed in recent years in order to adapt to more users' needs. The bridge rectification method is adopted, and the high-quality rectification trigger module is adopted, which has a simple line, small volume, and lightweight. The voltage is adjustable, the control system uses the PLC programmable controller to realize the automatic operation of iron removal and is suitable for use with the self-unloading iron remover.




The rectification control system and the corresponding self-unloading type of iron removal device are mainly used for removing iron parts in raw materials on non-magnetic raw material conveyor belts such as mines, docks, thermal power plants, cement, sugar, etc., to ensure the crushing equipment or the coal mill. Safety and improve the quality of the raw materials delivered.
    The rectification control system cabinet adopts front and rear door opening modes and can be installed in a floor-standing manner. The pressure regulating and rectifying components use a special radiator, and the air inlet window on the lower side of the cabinet can effectively accelerate the heat dissipation in the control cabinet and prolong the service life of the components in the cabinet.
    The main circuit of the rectification control system uses the power grid to directly connect to the three-phase power supply, and provides a voltage-adjustable DC power supply to the self-unloading iron remover via the bridge rectifier circuit, and the DC output end and the load magnet coil form a fixed closed-loop, and is attached Freewheeling diodes to avoid secondary overvoltage damage to the device. The control circuit is controlled by the programmable controller and the limit switch to realize the timing of the electric trolley rotating forward and reverse, and accordingly, the purpose of the self-discharging rotation operation to remove the iron is realized.
