System Module and Electrical Principle of Rotary Kiln

The direct current governor system of the rotary kiln uses the PID speed control system and regards the three-phase bridge controlled rectifier circuit as the drag system. In the site, the given value can be provided by the PCL. It directly uses the double-loop control system, which achieves the continuous speed. The speed ranges from 0 rev/min to 150 rev/min. The normal operation is from 1rev/min to 1.5 rev/min. The motor and the electromagnetic vibrating feeder use the frequency control. The frequency control is the stepless speed regulation for the alternating current machine so that the speed of the feeding hoist and the electromagnetic vibrating feeder is continuously adjustable. It adopts the PLC control to achieve the automatic feeding control and the adjustment control of the cooler to the electromagnetic vibrating feeder. The hardware of the control system reduces and the remote automatic control can be achieved.
In the fan electrical control system, the on-off control of every fan is achieved by using the PCL. Compared with the previous relay control mode, it can reduce a lot of hard wire to improve the safety of manual operation so that the operation of the fan can match to the actual working conditions to complete the processing requirements of active lime rotary kiln. There are end fan, primary fan and the secondary fan. The adjustment of the air door of the inlet of the primary fan and the secondary fan can be based on the pressure of the kiln end to adjust the air door of the inlet. We can achieve to the adjustment according to the opening regulation of the fluid coupling and the adjustment of the blast furnace, coke oven gas and combustion air mixing proportion and the adjustment of the cold air distribution valve of the preheater. In addition, you can monitor the running state of the fan, motor and other motors through the upper computer and adopt the overload protection.
The temperature automatic control system of the rotary kiln can be achieved through the PLC program, which cancels the previous tone table control mode and has greatly improved the degree of automation and control system accuracy. The temperature of the rotary kiln is controlled by the proportion of the gas and the ventilation rate.
