Description
Technical field
The device of coke discharging and dedusting rotation speed of fan can be automatically adjusted in coking production process the present invention relates to a kind of, belongs to burnt
Charcoal production equipment technical field.
Background technology
Pusher machine and coke discharging and dedusting blower fan are the visual plants of coking production, and pusher machine is according to discharging plan by coke from charcoal
Change a large amount of high-temperature flue gas containing coke powder produced during room is released, after leading the trapping of the large-scale air-suction cover on burnt grid, pass through
Interface flap valve enters dust collecting duct, then carries out purifying and dedusting at high speeds by coke discharging and dedusting blower fan.Discharge of the coke after finishing, wind
Machine by high-speed cruising switch to low speed operation, pusher machine complete pushing ram retreat, to fire door, flat coal, turn down fire door etc. action after, walk
Row then proceedes to coke pushing to next heat (batch) number, and coke discharging and dedusting blower fan switchs to high-speed cruising from low speed operation, continued at high speeds
Coke discharging dedusting is completed, and comes out of the stove by coke oven that high circulated at low velocity is produced order successively.
At present, the conversion instruction of coke discharging and dedusting blower fan high, low speed action is sent by pusher machine driver, on coke pushing operating desk
There is a rotary switch SA（Referring to Fig. 1 and Fig. 2）, when coke pushing starts, rotary switch is got to " ON " by driver, now rotary switch
Interior contacts are connected, and signal delivers to the speed governing relay KA of dedusting control room, speed governing through electric mill brush 1, the 4th electric mill road 2 successively
The main normally opened contact KA-1 closures of relay ,+DC24V high level signals are sent into PLC speed-regulating signal（Switching value）Input port,
Running PLC output signals by program makes to discharge of the coke the high speed dust removing contactor J1 actions of dedusting fan, high speed dust removing contactor J1
Normally open contact closure, the blower fan coupling device scoop tube that will discharge of the coke control connect, then scoop tube is run to a high position, rotation speed of fan from low level
From 300r/min raising speeds to 930r/min；After coke pushing terminates, operating desk rotary switch is got to " OFF " by driver, and now knob is opened
Close interior contacts to disconnect, speed governing relay coil dead electricity release, PLC switching input module does not have high level+DC24V signals
Input, runs PLC output signals make the to discharge of the coke low speed dedusting contactor J2 of dedusting fan by program and acts, then discharge of the coke blower fan
Coupling device scoop tube is again from run at high level to low level, and rotation speed of fan is from 930r/min reductions of speed to 300r/min.
Such a control mode is although relatively simple, but drawback is more, is mainly manifested in：1st, driver usually forgets in coke pushing
Or rotary switch is not opened in time, dust removing effects are undesirable when causing to discharge of the coke；2nd, after coke pushing terminates, driver in busy sometimes
Forget to close rotary switch, the dedusting fan that makes to discharge of the coke has been at high-speed cruising state, causes the waste of the energy.3rd, it is manually operated
The opportunity of rotary switch varies with each individual, and the time of coke discharging and dedusting blower fan high-speed cruising is difficult to, dedusting and energy-conservation effect synchronous with the discharging of the coke
Fruit can not reach optimal simultaneously.
The content of the invention
It is there is provided a kind of automatically controlling for coke discharging and dedusting blower fan it is an object of the invention to the drawback for prior art
