Description
(1) technical field
The utility model belongs to the electric magnetic iron remover corollary apparatus, is specifically related to the electric magnetic iron remover control system that uses on a kind of belt conveyer.
(2) background technology
Adopt the belt conveyer electric magnetic iron remover to accomplish to the deironing of industrial material more.And in magnetic material, remove harmful ironware is a very complicated situation, and different on-the-spot material grades are all different, all can influence the parameter and the function of electric magnetic iron remover switch board because of reasons such as the interference of site environment, vibrations.Deironing control system common on the market all is the panel button operation, and is then powerless for the intelligent demand of user Geng Gao.
(3) summary of the invention
The purpose of the utility model provides a kind of intelligent electric deironing device and controls system, changes the man-machine interface operation through simple connection, realizes the setting of parameter and function, and is simultaneously simple to operate, the reliability of enhanced system.
The technical scheme that the utility model adopts is: intelligent electric deironing device control system comprises main circuit and control circuit; Main circuit is to be connected belt motor through circuit breaker Q F2 with contactor KM1 respectively by supply voltage, through going out the two ends that magnitude of voltage adjustable in the certain limit is added to magnet exciting coil YA1, YA2, YA3 through rectification behind rectification circuit VC1, VC2, the VC3 again behind circuit breaker Q F3, QF4, QF5 and contactor KM2, KM3, the KM4; Control circuit is to receive the metal detector signal through PLC belt motor, magnet excitation and two secondary magnetic pole excitations are controlled; The signal of PLC is sent in the touch-screen, and touch-screen control contactor KM1 realizes the running of belt and the start and stop that control contactor KM2, KM3, KM4 drive each excitation.
The utility model can satisfy the intelligent requirements of user Geng Gao, carries out various parameters with touch-screen and sets the debugging of fault alarm and function.Increase the reliability that temperature and humidity control circuit improves system simultaneously.XMT can monitor the temperature of main equipment magnet exciting coil in real time in the temperature and humidity control circuit; It is inner that the RV16 thermocouple inserts equipment master magnet exciting coil YA1, because temperature is to influence very one of essential condition that coil produces the size of magnetic force, the too high magnetic force that will make of temperature reduces; Passing through the magnetic degree of depth all can weaken; So do not reach the requirement of operational height place field intensity, the ironware in the material just can not be picked up and do not removed, and temperature is too high may burn coil when serious.So temperature control circuit meeting capping and lower-limit temperature value when detecting coil temperature above lower limit, can receive signal in the touch-screen; Alarm condition occurs, reminds people is noted the temperature rise employing series of solutions of coil, when temperature surpasses higher limit; Defence program begins to carry out among the PLC; KM2, KM3, KM4 cut off the power supply simultaneously, and each excitation of equipment stops, and the KM1 belt that also cuts off the power supply shuts down.Reached the purpose of protection equipment.Touch-screen can the detail record alert data simultaneously.
(4) description of drawings
Accompanying drawing is the circuit theory diagrams of the utility model.
(5) specific embodiment
The utility model is to the application and the protection of electric magnetic iron remover; For the electric magnetic iron remover excitation provides dc source and excitation control; The main excitation of electric magnetic iron remover, 1# secondary magnetic pole excitation, 2# secondary magnetic pole excitation voltage are respectively 0～450V DC, 0～320V DC, 0～320V DC; Three phase network voltage is 380V AC; Obtain the main pole coil that 0～450V DC voltage is sent to electric magnetic iron remover through three-phase half controlled bridge formula constant current rectification, control the constant current rectification entirely through individual event and obtain the secondary magnetic pole coil that 0～320V DC voltage is sent to electric magnetic iron remover, and the adhesive through A.C. contactor with discharge the excitation of controlling tramp iron separator; The belt motor power supply is through getting into belt motor behind the thermal overload relay, and the adhesive through A.C. contactor with discharge the running of controlling belt motor.
Control circuit has touch-screen, only needs a serial port data line to be connected between touch-screen and the PLC.Both can control belt motor and magnet exciting coil by touch-screen, and also can adjust parameter, record is reported to the police, the time number of times of fault, and accumulation workload etc. can also be monitored the duty with simulated field in real time.
The utility model also comprises temperature and humidity control circuit, and it is inner that the thermocouple RV16 of temperature and humidity control circuit inserts main magnet exciting coil YA1.Temperature controller XMT in the temperature and humidity control circuit can monitor the coil inside temperature in real time, and the undesired size that will influence magnetic force of coil temperature seriously may be burnt coil.If coil temperature is in the overtemperature state, belt and excitation quit work.Temperature and humidity controller W-H can regulate the humiture in the switch board subenvironment automatically, and touch-screen is operated in the metastable working environment.
