The utility model compared with prior art has following advantage:
Adopt PLC and frequency converter to match, variable frequency regulating speed control replaces DC speed regulation, and excursion is wider, and control system is simple, and thus reduce component count and the volume of train, motor-driven parts tail off, and thus fundamentally save energy; In addition, the parts of whole system tail off, and structure becomes simple, so maintenance capacity and maintenance difficulty diminish all accordingly, the maintenance personal in factory can keep in repair most equipment fault; Finally, hot-cast aluminum recycling place working environment is high temperature, and after using novel control system instead, personnel can control in control room remotely, improve the working environment of workman.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of hot-cast aluminum recycling frequency changing regulating speed control apparatus, comprise 380V power supply 1, input equipment 2, model is the PLC 3 of S7-200, model is first frequency converter 4 and the first Asynchronous Frequency-variable motor 5 of MM440, first reductor 6, cast aluminium hot-rolling mill active roller 7, return idler 8, second frequency converter 9, second Asynchronous Frequency-variable motor 10, second reductor 11 and cast aluminium hot-rolling mill aluminium sheet reel 12, described 380V power supply 1 is that the first frequency converter 4 and the second frequency converter 9 are powered, described input equipment 2 is touch-screen, be connected by RS485 control line between touch-screen with PLC 3, the control terminal of the first frequency converter 4 is connected with the output of PLC 3, first frequency converter 3 is connected with the first Asynchronous Frequency-variable motor 5, the motor shaft of the first Asynchronous Frequency-variable motor 5 is connected with the power shaft of the first reductor 6, the output shaft of the first reductor 6 is connected with cast aluminium hot-rolling mill active roller 7, first reductor 6 drives cast aluminium hot-rolling mill active roller 7 to rotate, cast aluminium hot-rolling mill active roller 7 and below are provided with return idler 8, gap is provided with between cast aluminium hot-rolling mill active roller 7 and return idler 8, this gap can produce the requirement of aluminium according to user, adjust.
The control terminal of the second frequency converter 9 is connected with the output of PLC 3, second frequency converter 9 is connected with the second Asynchronous Frequency-variable motor 10, the motor shaft of the second Asynchronous Frequency-variable motor 10 is connected with the power shaft of the second reductor 11, and the output shaft of the second reductor 11 is connected with cast aluminium hot-rolling mill aluminium sheet reel 12.
First Asynchronous Frequency-variable motor 5 controls output speed by the first frequency converter 3, the second Asynchronous Frequency-variable motor 10 controls output speed by the second frequency converter 9, the control tach signal of two frequency converters comes from PLC 3 simultaneously, PLC 3 can be controlled by touch-screen 2, and control signal is sent to PLC by RS485 control line.
