Fig. 2 is an embodiment Controlling System synoptic diagram.
Embodiment
Controlling System of the present invention has 2 kinds of operating mode: (1) automatic mode, and after the instruction that receives stifled iron notch, clay gun is beaten the mud amount and is beaten mud speed according to predefined, finishes stifled iron notch automatically by PLC controller (programmable logic controller); (2) remote manual control pattern can realize arbitrary single movement of clay gun.
As shown in Figure 1, Hydraulic clay gun Controlling System before the State of Blast Furnace comprises clay gun, hydraulic control unit, automatic control unit and remote control control unit; The remote control control unit comprises remote control transmitter, receiver of remote-control sytem; Described remote control transmitter is communicated by letter with receiver of remote-control sytem by wireless signal, and receiver of remote-control sytem links to each other with automatic control unit, and automatic control unit links to each other with clay gun by hydraulic control unit; Also comprise detecting unit, detecting unit is connected between clay gun, the automatic control unit.
As shown in Figure 2, automatic control unit comprises PLC controller, server, and server links to each other with the PLC controller, and the PLC controller is sent to server with the data of detecting unit collection, server is assigned the controller to PLC with remote control command, realizes the Long-distance Control to clay gun; The remote control control unit comprises remote control transmitter, receiver of remote-control sytem; Hydraulic control unit comprises proportional reversing valve, pressure compensator; Remote control transmitter is communicated by letter with receiver of remote-control sytem by wireless signal, receiver of remote-control sytem transmits guidance command to the PLC controller, the PLC controller sends to proportional reversing valve by the amplification plate with control signal and it is controlled, thereby realizes the long-range wireless remote control of Hydraulic clay gun action and speed; Detecting unit comprises detector and display unit such as under meter, pressure transmitter, the input terminus of under meter, pressure transmitter is connected beating on the mud cylinder hydraulic circuit of clay gun, the output terminal of under meter, pressure transmitter links to each other with the PLC controller, and display unit links to each other with the PLC controller.Display unit adopts HMI (human-computer interaction interface, Human Machine Interface).
The PLC controller comes the exciting current size of control ratio electro-magnet by the control current size of program setting controller output template.
Clay gun revolution is with adopting proportional reversing valve, than be easier to realize clay gun open slowly, at full speed, the functional requirement that stops slowly.Reduce device start and the impact when stopping, prolonging the work-ing life of clay gun, realize that by control device clay gun contacts with the soft of iron mouth simultaneously
Clay gun is beaten mud and is adopted electro-hydraulic proportion reversing valve, be used to control the action of playing the mud oil cylinder, can regulate the mud speed of beating of clay gun, make under meter on the mud cylinder hydraulic circuit by being installed in, can detect the numerical value that clay gun is beaten the mud amount, this numerical value is record on the PLC controller, and on display unit, show, automatically beat mud according to the mud amount of setting of beating, when beat the mud amount greater than set(ting)value 5% the time, clay gun stops dozen mud automatically.
The pressure compensator that is connected with proportional reversing valve, general setting pressure reduction is 1Mpa, the variation of load pressure can not exert an influence to valve port pressure reduction, adopt pressure compensator to guarantee that the valve port pressure reduction of proportional reversing valve is constant, the output flow of proportional reversing valve is directly proportional with control current like this, thus can by the outward current of control output template realize to Hydraulic clay gun speed of rotation, beat mud speed and accurately control.
Clay gun is connected with pressure transmitter, is pressing big gun pressure to reach the 25Mpa of setting, and after keeping for 10 seconds, clay gun is played the mud action and started automatically.Pressure transmitter exports detected parameter to HMI by the PLC controller, and then system can detect in real time, shows and write down and beat mud pressure, beats the mud amount, beats mud speed and press the big gun pressure and other parameters.The operator can be by the further Optimizing operation of these parameters, for online equipment fault diagnosis provides condition, and HMI record material automatically in addition; Can the format print that data converts form to be come out.The operator can also be by the direct operating device of graphic interface of HMI.
PLC will detect in real time beats mud pressure, beat the mud amount, beat mud speed and press the big gun pressure and other parameters to be uploaded to server analysis, further Optimizing operation.
Controlling System of the present invention makes the workman to manoeuvrable, convenience, the safety of Hydraulic clay gun, can be widely used in all types of large, medium and small blast furnaces.
