Brief description of the drawings
Fig. 1 is the structural representation that the filling of magnesium metal reduction jar furnace charge pelletizing strength and reducing slag strength are taken off the automatic electrical control system of getting all-in-one.1-power supply, 2-control module, 3 operational modules
Embodiment
Below in conjunction with drawings and Examples, the present invention is elaborated.These accompanying drawings are the schematic diagram of simplification, the basic structure that only explanation is invented in a schematic way, and therefore it only shows the formation relevant with the present invention.
embodiment 1 Controlling System detailed annotation:
The present invention includes power supply (1), control module (2), operational module (3), system works module (2) comprises roots blower motor, fly-ash separator id-motor, Hydraulic System Oil pump motor, main drive gear motor, running wheel motor, micro-air compressor motor, the motor of rotary conveyor, pressure unit, magnetic valve, travel switch, system control module (3) comprises roots blower motor inverter, protect the control unit of each electrical fault, operating panel, remote manipulator system is divided into telepilot control, operator panel buttons control, PLC controls three parts.Telepilot adopts telepilot to control while being the normal running of major control parts.Control button when operating panel push button is urgent, the operation of carrying out in the time that PLC or telepilot break down.Major control core adopts PLC controller, by using the program controling module of PLC controller, according to strength load, strength takes off and gets required air quantity and programme by PLC, reached the object of controlling air quantity by PLC controller control frequency transformer.Wherein, strength filling functions is the method that the control mode of the segmentation that adopts PLC controller, timesharing is controlled frequency transformer, PLC controller control roots blower frequency transformer carries out the frequency reducing control of segmentation, timesharing, by the rotating speed of Frequency Converter Control roots blower, the air quantity of controlling roots blower with this, reaches strength and loads the function of furnace charge pelletizing.By pressure unit, the process Wind pressure of loading furnace charge pelletizing is tested, through pressure unit, blast is converted to by DC4～20mA constant current ring standard signal of linear scaling output, send in PLC programming module and calculate, according to program calculated result, in the time that blast is greater than 10KPa, PLC controller sends the instruction that stops loading furnace charge pelletizing, equipment is received the instruction of PLC controller, stops the filling of furnace charge pelletizing.Meanwhile, in PLC controller, carry out the time setting that furnace charge pelletizing is loaded, controlled, monitor the process that whole furnace charge pelletizing is loaded by PLC, in the time reaching the filling time of setting in PLC controller, stopped the filling of furnace charge pelletizing; Strength is taken off and is got analog quantity control mode that function the adopts PLC controller method to Frequency Converter Control, and by the rotating speed of Frequency Converter Control Root's blower, the air quantity of controlling Root's blower with this, reaches strength and take off the function of getting furnace charge pelletizing.
System control is divided into telepilot control, the control of electric control box panel button, PLC and controls three parts.Telepilot is major control parts, adopts telepilot to control when normal running; Control button when electric control box button is urgent, the operation of carrying out in the time that PLC or telepilot break down.
embodiment 2 manually takes off slag operation:press " main drive gear motor advances " button, the pipe of skimming is goed ahead automatically, until after detecting that travel switch is opened, the pipe of skimming will halt.Now, PLC program is received the signal that puts in place of travel switch, and PLC controller automatically switches to by controlling frequency transformer the required frequency of skimming, now, open " Pneumatic three-way valve ", the air quantity that system will be controlled roots blower according to the frequency of skimming of setting reaches the function of skimming.
embodiment 3 takes off slag operation automatically: press " skim and automatically open/stop " button, PLC controller carries out whole actions of skimming automatically according to sequence of control, the main drive gear operation of skimming that automatically moves ahead, and automatically open " Pneumatic three-way valve ", until stop moving ahead after travel switch being detected, now, PLC controller automatically switches to by controlling frequency transformer the required frequency of skimming, and the air quantity that system will be controlled Root's blower according to the frequency of skimming of setting reaches the function of skimming.
the manual loading operation of embodiment 4: by charging skim frequency select button, be chosen as charging, " the charging tube oil cylinder advances " button on push panel, charging tube is goed ahead automatically, until detect after travel switch, halts." rotary conveyor motor " button on push panel, starts to feed.Now, by pressure tester, charge amount is tested, through pressure unit, the force value of charge amount is converted to by DC4～20mA constant current ring standard signal of linear scaling output, send in PLC programming module and calculate, according to program calculated result, PLC controller control frequency transformer carries out the frequency reducing control of segmentation, control the air quantity of Root's blower with this, thereby reach the loading to furnace charge pelletizing.Meanwhile, in PLC, carry out the setting of charge time, when charge time reaches the time of setting in PLC, stopped charging.
real execute example 5 automatic charge operations:" charging automatically " button on push panel, equipment, by according to the setting of PLC controller, completes whole actions of charging automatically, and frequency transformer is carried out to the frequency reducing control of segmentation, control the air quantity of roots blower with this, thereby reach the loading to furnace charge pelletizing.
Will be appreciated that those skilled in the art in the art, above-described embodiment is only for the present invention is described, not be used as limitation of the invention, as long as in indication spirit scope of the present invention, variation, the modification etc. of above-described embodiment all will be belonged in the scope of the claims in the present invention.
