In order to achieve the above object, the utility model is by the following technical solutions:
The device of a kind of automatic operation and control still kettle, comprise electrical control cubicles and by-pass cock, the control signal output of described electrical control cubicles connects the control signal input of by-pass cock, by-pass cock is used to be arranged on the pipeline of still kettle pressure entrance, also comprise the control computer, PLC, the voltage supply system of still door and clip gauge tap and driving still door and clip gauge tap, described control computer and PLC communicate, the control signal output of PLC connects the signal input part of electrical control cubicles, the control signal output of PLC connects the control signal input of the voltage supply system that drives still door and clip gauge tap simultaneously, the control signal output that drives the voltage supply system of still door and clip gauge tap connects the control signal input of still door and clip gauge tap, still door and clip gauge tap are used to be arranged on the still door of still kettle, and the feedback signal output of still door and clip gauge tap connects the feedback signal input of PLC.
Described still door and clip gauge tap comprise that clip reaches the position and closes to put in place near switch, clip and reach the position near switch, still door and close near switch and still door and put in place near switch.
Be provided with superpressure, overtemperature alarm circuit and muffling circuit in the circuit of described PLC.
Adopt above technical scheme can reach following technique effect:
Because the utility model adopts control computer control PLC, and then control electrical control cubicles automatically by PLC, and then realization is operated automatically, the control still kettle, also be provided with still door and clip gauge tap simultaneously, still door and clip gauge tap feed back to the control computer with the status signal of still kettle, can show the working condition of still kettle intuitively by the control computer.
Description of drawings
Fig. 1 is a theory diagram of the present utility model.
The specific embodiment
As shown in Figure 1: the utility model comprises the control computer, PLC, electrical control cubicles, by-pass cock, the voltage supply system of still door and clip gauge tap and driving still door and clip gauge tap, described control computer and PLC communicate, the control signal output of PLC connects the control signal input of electrical control cubicles, the control signal output of PLC connects the control signal input of the voltage supply system that drives still door and clip gauge tap simultaneously, the control signal output of electrical control cubicles connects the control signal input of by-pass cock, and by-pass cock is used to be arranged on the pipeline of still kettle pressure entrance; The control signal output that drives the voltage supply system of still door and clip control gate connects the control signal input of still door and clip control gate, and still door and clip gauge tap are used to be arranged on the still door.The feedback signal output of described still door and clip gauge tap connects the feedback signal input of PLC.
The voltage supply system of driving still door of the present utility model and clip gauge tap adopts hydraulic pressure or air pressure, by-pass cock comprises electricity accent valve, the magnetic valve on the pipeline that is arranged at the still kettle pressure entrance, and described electricity transfers valve and magnetic valve to be used for controlling the interior pressure of still kettle; Still door and clip gauge tap comprise that the clip that is arranged on the still kettle still door reaches the position and closes to put in place near switch, clip and reach the position near switch, still door and close near switch and still door and put in place near switch, and described still door and clip gauge tap are used for controlling the switch of still door.During work, the staff sends instruction by the control computer and gives PLC, PLC control drives the voltage supply system output pressure driving still door and the clip gauge tap of still door and clip gauge tap and opens, and the status signal of still door and clip gauge tap feeds back to PLC simultaneously.Still door and clip gauge tap are opened the back staff and can be fed intake, feed intake and give PLC by the computer output order again after finishing, the voltage supply system output that the PLC output order give to drive still door and clip gauge tap opposite pressure when opening the still door, still door and clip gauge tap are just closed like this, and the state of still door and clip gauge tap also can feed back to PLC simultaneously.After PLC receives the signal of still door and clip gauge tap closure, the staff just can send instruction by the control computer and give PLC, the action of PLC control electrical control cubicles, and then automatically controlled driving by-pass cock is opened, the outside provides pressure for still kettle like this, pressure in the while still kettle, the status signal of temperature feeds back at any time and sends PLC to, and then feed back to the control computer, pressure condition in the still kettle just can show on the control computer by PLC, the control computer can require according to the processing parameter of input to transfer valve to regulate to magnetic valve and electricity: if the pressure in the still kettle is excessive, pressure condition in the still kettle can feed back on the control computer, the control computer is provided with still kettle internal pressure control process curve and pressure, the time data input point, the control computer can compare according to the setting value of signal that feeds back and standard, turn the aperture that electricity is transferred valve by sending instruction down to PLC control electrical control cubicles output control signal, be used for reducing the pressure and temperature in the still kettle; If the still kettle internal pressure is low excessively, sends instruction after the same setting value according to signal that feeds back and standard of control computer compares and transfer big electricity to transfer the aperture of valve to PLC control electrical control cubicles output control signal.
