Fig. 2 is the control system schematic diagram.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, this practical technical scheme is further specified.
Referring to Fig. 1, shown in Figure 2, the PLC basic module is connected by communication cable with touch-screen, the PLC basic module is connected with I/O module, I/O module, I/O module, I/O module, I/O module, I/O module, I/O module, the PLC basic module is connected by communication cable with decoder, in the switch board 18 of packing into; Switch board 18 is placed near main body 1 equipment.The PT01 of pressure sensor, PT02, PT03 are connected to the I/O module in the switch board 18; Position sensor 6 is connected to the I/O module in the switch board 18; Filter cloth seam detector 13 is connected to the I/O module in the switch board 18; Counting gear 12 is fixed on the axle of encoder 11, and counting gear 12 is placed on the filter cloth 17.V01 in the valve, V02, V03 are connected with I/O module in the switch board 18; Filter cloth drive motors 9 is connected with I/O module in the switch board 18; Last sheet frame drives hydraulic cylinder 16 and sealing fluid cylinder pressure 15 and is connected with I/O module in the switch board 18.
When position sensor 6 no signals, then the PLC basic module judges that at this moment upward sheet frame 5 is at upper position; Again position sensor 4 is judged that if do not have, then system-down is reported to the police; If have, the PLC basic module then sends unlocking signal, and pin 2 is opened, this moment position sensor 4 no signals, system does not report to the police.The PLC basic module sends the driving signal by the I/O module, and sheet frame drives hydraulic cylinder 16 actions in the driving, and last sheet frame 5 comes downwards to position sensor 6 monitoring locations along column 3, and position sensor 6 sends the signal that puts in place to the I/O module, and is sent to the PLC basic module; The PLC basic module stops to send driving and goes up the signal that sheet frame drives hydraulic cylinder 16 according to main program; Send sealing signal to sealing fluid cylinder pressure 15 by the I/O module then, 15 actions of sealing fluid cylinder pressure, drive sealing plate 8 and move up to sealing plate position sensor 7 monitoring locations along column 3, sealing plate position sensor 7 sends the signal that puts in place to the I/O module, and be sent to the PLC basic module, realize sealing, and filter cloth 17 is sealed in up and down between sheet frame.The PLC basic module stops to send driving sealing plate hydraulic cylinder 15 actuating signals according to main program, and sealing fluid cylinder pressure 15 stops action, and sealing plate stops up.Afterwards, the PLC basic module sends the charging signal according to main program by the I/O module, opens the pipeline technology valve V02 in the valve, the beginning charging, and part filtrate flows into Drainage pipe and discharges through behind the filter cloth 17 simultaneously.PT02 in the pressure sensor is sent to the PLC basic module with the feed pressure value by the I/O module simultaneously, and the PLC basic module stops the charging signal through delaying time, sending, and stops charging.Afterwards, the PLC basic module sends the V01 of start signal to the valve by the I/O module, and pipeline technology valve V01 opens, and water under high pressure is put into sheet frame 5, begins material is pushed, and most of filtrate flows into the Drainage pipes discharges through filter cloth 17.The PLC basic module picks up counting, and PT01 feeds back to the PLC basic module with the force value of water under high pressure by the I/O module in the while pressure sensor.When the time then, the PLC basic module sends the pipeline technology valve V01 of shutdown signal to the valve by the I/O module, pipeline technology valve V01 closes, and stops extruding.Afterwards, the PLC basic module sends the pipeline technology valve V03 of start signal to the valve by the I/O module, washes cake water and flows into, begin filter cake is washed, and time-delay.When the time then, the PLC basic module sends the pipeline technology valve V03 of stop signal to the valve by the I/O module, pipeline technology valve V03 closes.The PLC basic module sends the pipeline technology valve V01 of start signal to the valve once more by the I/O module, and pipeline technology valve V01 opens once more, and beginning is extrusion process for the second time.Afterwards, the PLC basic module sends the sealing fluid cylinder pressure 15 of deblocking signal to the hydraulic cylinder by the I/O module, thereby it is descending along column 3 to drive sealing plate 8, realize deblocking, when sealing plate position sensor 7 no signals, and through time-delay, the PLC basic module is judged sealing plate 8 deblocking.Afterwards, the PLC basic module sends upward signal to the last sheet frame in the hydraulic cylinder by the I/O module and drives hydraulic cylinder 16, thereby last sheet frame 5 is up along column 3, while position sensor 6 no signals, through time-delay, the PLC basic module is judged upward sheet frame 5 in-positions, then the PLC basic module sends the locking signal by the I/O module, pin 2 is carried out locking action, and when position sensor 4 had signal, PLC basic module judgement pin 2 had been locked.Afterwards, the PLC basic module sends by the I/O module and drives signal to filter cloth drive motors 9, filter cloth drive motors 9 starts and drive drive roll 10 rotates together, driven voller 14 carries out the trace adjusting simultaneously, with filter cloth 17 appropriate tensionings, and cooperate drive roll 10 to rotate together, make filter cloth 17 begin to walk about, and drive counting gear 12 and rotates together, thereby make that encoder 11 begins to count, and encoded signal sends back the decoder in the switch board 18, decoder is passed signal back the PLC basic module, the PLC basic module begins the distance that filter cloth 17 is passed by is calculated, and at this moment, filter cloth seam detector 13 is the metal seam of monitoring filter cloth 17 in real time.After filter cloth 17 was passed by the distance that main program sets, PLC1 sent by the I/O module and stops to walk the cloth signal, thereby makes filter cloth drive motors 9 stop operating, and then filter cloth 17 also stops to walk about.When filter cloth 17 is walked about, also will squeeze the filter cake of doing and lay down.So far, the one action circulation is finished, and prepares cycle operation next time.In the above-mentioned course of work, whole working condition shows by touch-screen, so that operator's monitoring.
