All-dimensional safety protection for main machine equipment and on-spot production is achieved in a high automation mode.
Description
(1) technical field
The utility model belongs to the corollary apparatus of high gradient tramp iron separator.Be specifically related to be fit to the high belt speed in harbour, the high gradient tramp iron separator electric control system of the environment that material is thick.
(2) background technology
Along with the fast development of national economy, the industries such as China's iron and steel, electric power, coal have also obtained the development of advancing by leaps and bounds, and the raw material that needs is more, simultaneously the quality of raw material is also had higher requirement, and the task of deironing also is more and more difficult.The at present domestic meticulous equipment for removing ferric ion that can reach the convey materials cleaning that also is fit to the major port use fully.
(3) summary of the invention
Goal of the invention of the present utility model provides a kind of high gradient tramp iron separator multifunction protection electric control system, and it can increase substantially the precision of high gradient tramp iron separator, and can adapt to the high belt speed in harbour, environment that material is thick, has multiple protection functions.
The technical solution adopted in the utility model is: high gradient tramp iron separator multifunction protection electric control system comprises main circuit and control circuit, main circuit is divided into three the tunnel after passing through circuit breaker Q F1 by the 380VAC supply voltage, one the tunnel gives rectification circuit MODC power supply behind the main contacts of circuit breaker Q F2, contactor KM1, voltage is added on the field coil YA after the rectification; Give belt motor M1 power supply behind the second tunnel main contacts through circuit breaker Q F3, contactor KM2, the thermal overload relay FR1, Third Road is powered through contactor KM3 main contacts, thermal overload relay FR2 oil-feed pump motor M 2, and by giving three fan electromotor M3, M4, M5 power supply through thermal overload relay FR3, FR4, FR5 respectively behind the contactor KM4 main contacts.
Control circuit is powered to controller PLC by the 220V supply voltage of transformer TC1 output, power to temperature controller WKY through overtemperature alarm relay K A7 coil simultaneously, controller PLC out-put supply positive pole is respectively through excitation start-stop button SB1, belt start-stop button SB2, the belt motor thermal overload relay FR1 of often making war, the normal battle of overtemperature alarm relay K A7, the signal output point of current sensor AS1, the Oil pump electrical machinery thermal overload relay FR2 of often making war, emergency stop push button SB5, belt deviation switch SQ1, SQ2 and three blower fan thermal overload relaies FR3 of often making war, FR4, FR5 connects the signal input part of controller PLC; The signal output part of controller PLC connects the supply voltage negative pole through contactor KM1 coil, contactor KM2 coil, contactor KM3 coil, contactor KM4 coil and hummer YB1, YB2, YB3, YB4, YB5 respectively.
The course of work of the present utility model is: when excitation start-stop button SB1 is effective, and contactor KM1 adhesive, the excitation of realization field coil.The variation of current sensor AS1 Real Time Monitoring exciting current; When belt start-stop button SB2 is effective, the running that iron belt is unloaded in contactor KM2 adhesive control; When excitation starts, the common control section that forms efficient heat abstractor of simultaneously adhesive of contactor KM3, KM4.Main process equipment is different from the difference that the common electrical deironing device is exactly radiating mode; what fuselage adopted is the forced-oil-cooling circulation that the oil circulation cooling adds fan electromotor; therefore more outstanding to the protective effect of whole main frame; whole control section is by controller PLC central authorities centralized control, and Automatic Control is safe and reliable.Concrete defencive function is as follows:
Temperature protection: in the main pole of coil, inserted temperature sensor RV1 and matched with switch board temperature controller WKY; when the temperature in the coil reaches the first setting value; the KA7 coil gets electric this moment overtemperature signal and sends in the PLC, and output overtemperature alarm hummer YB2 dodges and rings.When the temperature in the coil reached the second setting value of setting, overtemperature output signal W, the N on the temperature controller WKY disconnected, so the KM1 disconnection, and the main frame excitation stops.
Current protection: current sensor AS1 Real Time Monitoring exciting current, when current anomaly was arranged, output signal L, the M of AS1 entered PLC, and output current is unusual simultaneously to determine to stop excitation behind the current anomaly after PLC processes, and alarm buzzer YB4 is effective.
Electric motor protecting: FR1 is respectively the thermal overload relay of belt motor Oil pump electrical machinery and fan electromotor to FR5; its signal is sent in the PLC, and when there being abnormal conditions to occur, thermal overload trips at once; motor power is cut off, and PLC output motor fault-signal is to hummer YB1.
Oil stream and oil level protection: in the oil circuit of main frame, designed oil flow relay and oil level switch; when oil circulation is stopped up or had oil level its abnormal signal that descends then that makes of the situation such as leakage of oil all can send in the PLC; and stop excitation, and the output oil starvation is reported to the police, and hummer YB5 dodges and rings.
Belt deviation protection: belt deviation switch is installed on the main frame, when belt reach one-level sideslip SQ1 when effective signal send into PLC, export sideslip alerting signal YB3 this moment, when sideslip reach secondary sideslip SQ2 when effective PLC can stop belt control and make the KM2 outage.
Emergent stopping: all outputs of emergency stop push button PLC of pressing when some uncontrollable or urgent special circumstances occur equipment on the switch board are all interrupted.
The utility model has satisfied the relatively abominable production environment of domestic and international harbour convey materials, the realization of high automation omnibearing safeguard protection to main process equipment and produced on-site.
