Description
Technical field
The utility model belongs to coking production field more particularly to belt transportation system automatic safety device.
Background technique
The coke needs of coking production transport coke storage bunker, since the capacity of coke storage bunker is relatively large, according to production
It is required that needing to store the coke of 600-1000t, drop has 50m, and such belt is crucial belt, since the transport capacity of belt limits
System, therefore when coke has just entered belt system, is respectively provided with the device of belt measurement electric current.
The belt transportation system of coking production area controls coordinated operation, the fortune of each belt by PLC program between each other
Row signal takes the auxiliary to belt main contactor to prescribe, and belt is run after main contactor is attracted, while the auxiliary of main contactor
Closure is prescribed, belt run signal is sent into the input module of PLC, program detects the operating status of each belt with this, as long as
The auxiliary of belt main contactor prescribes closure, and PLC program is with regard to the normal coordinated operation of default system.Since fluid coupling is mounted on
Between motor and speed reducer, after fluid coupling alters oil, belt main contactor is still within attracting state, the auxiliary of main contactor
It prescribes and is still closed, belt motor runs well, but belt shuts down with the disengagement of head motor, former PLC program design
It can not detect above-mentioned malfunction, there are serious design defect.Cause belt chute is not smooth to result in blockage or belt
Overload in turn results in belt and breaks accident, will cause coke oven that it is more than hour to stop production 16, influences the economic benefit of coke oven production
And the service life of coke oven.
Utility model content
The purpose of the utility model is to overcome the above problems and operation that is insufficient and providing a kind of raising belt system to imitate
Rate increases coke output, guarantees that the Novel waistband of safety and stability production runs automatic safety device.
A kind of Novel waistband operation automatic safety device, including current transformer, intelligent monitoring instrument, PLC control system,
The current transformer is arranged on motor load line, and auxiliary node is arranged on motor load line, current transformer connection
Intelligent monitoring instrument, the intelligent monitoring instrument connect PLC control system, comparing function mould are arranged in the PLC control system
Block, time-delay relay, auxiliary relay, the auxiliary node connect PLC control system.
Alternating current is incuded by current transformer, and the AC current values sensed are converted to 4- by intelligent monitoring instrument
The DC simulation signal of 20mA incudes alternating current, the alternating current that intelligent monitoring instrument will be sensed by current transformer
Value is converted to the DC simulation signal of 4-20mA, by compare in PLC control system functional module, time-delay relay, auxiliary after
The closure of electrical equipment control auxiliary node avoids high current when belt starting and the moment impact load in Coke Transport.
The beneficial effects of the present invention are: it is swift in motion using the utility model control system, stops entire belt system
Operation.The maximum value of belt filled load is effectively limited by accurately controlling the electric current of belt motor, effectively avoids fluid power
Coupler alters the generation of oily accident, guarantees the safe and reliable operation of belt system.
Detailed description of the invention
Fig. 1 is that the utility model belt runs automatic safety device structural schematic diagram.
1 it is current transformer in figure, 2 is intelligent monitoring instrument, 3 is PLC control system, and 4 be motor, and 5 be auxiliary node.
Specific embodiment
A kind of Novel waistband operation automatic safety device, including current transformer 1, intelligent monitoring instrument 2, PLC control system
System 3, the current transformer 1 are arranged on 4 load line of motor, and auxiliary node 5 is arranged on 4 load line of motor, and electric current is mutual
Sensor 1 connects intelligent monitoring instrument 2, and the intelligent monitoring instrument 2 connects PLC control system 3, sets in the PLC control system 3
Comparing function module, time-delay relay, auxiliary relay are set, the auxiliary node 5 connects PLC control system 3.It is mutual by electric current
Sensor 1 incudes alternating current, and intelligent monitoring instrument 2 believes the DC simulation that the AC current values sensed are converted to 4-20mA
Number, the closure of auxiliary node 5 is controlled by comparing functional module, time-delay relay, auxiliary relay in PLC control system 3, is kept away
Open high current when belt starting and the moment impact load in Coke Transport.
Current transformer 1 and auxiliary node 5 is arranged in the utility model on motor load line, passes through PLC control system 3
Comparing function module, by belt run actual current value be compared with setting value, when belt run actual current value
When being greater than the set value, comparing function block movement conducting, institute's band auxiliary relay is instantaneously closed, and drives time-delay relay, delay
Relay starts to clock.Time-delay relay presets the time.When the closure duration of auxiliary relay is less than setting time value
When, time-delay relay does not work.When the closing time of auxiliary relay is more than setting time value, time-delay relay is instantaneously closed
It closes, and drives an auxiliary relay branch, the auxiliary of auxiliary relay, which prescribes, is incorporated to belt system emergency stop circuit.When energization is prolonged
When relay auxiliary when prescribing closure, the auxiliary of auxiliary relay prescribes instantaneous closure, belt system emergency stop circuit behavior, fortune
Belt system in row stops immediately.Belt system stops, the run signal power-off restoration of belt, and auxiliary prescribes disconnection, leads to
Electric time-delay relay, comparing function block, auxiliary relay etc. all reset, and are ready for lower task.
