The foregoing is to be understood as belonging to the specific meanings in the present application as appropriate to the person of ordinary skill in the art.
The method for processing the fault of the floating rod of the jigger in the embodiment of the application, as shown in figure 1, comprises the following steps:
step S101: responding to the floating rod fault early warning signal, and executing the step S102;
step S102: controlling the opening of the discharge gate plate to increase step by step;
step S103: if the floating rod fault early warning signal is not released, executing step S104;
step S104: if the opening degree of the discharge gate plate is the threshold value of the opening degree of the gate plate, executing the step S105, otherwise, returning to the step S102;
step S105: controlling the opening degree of the air valve to be gradually reduced;
step S106: if the floating rod fault early warning signal is not released, executing step S107;
step S107: if the air valve opening is the air valve opening threshold, executing the step S108, otherwise, returning to the step S105;
step S108: triggering a fault shutdown.
Specifically, a float rod detection device can be arranged to detect the float rod, and the float rod detection device sends out a float rod fault early warning signal when considering that the float rod is in fault. Generally speaking, the reason why the floating rod breaks down most of the time is that the bed layer thickness in the jigging chamber is too thick, and the material volume is too much and leads to the floating rod can't move, and this kind of trouble can be got rid of through reducing the bed layer thickness through the reduction material.
Step S102 is executed after the floating rod fault early warning signal is received, and the opening degree of the discharge gate plate is controlled to be increased step by step so as to increase the discharge amount and reduce the thickness of the bed layer. Because the opening of the discharge gate plate cannot be infinitely increased, when the opening of the discharge gate plate reaches a gate plate opening threshold (for example, the gate plate opening threshold is set to 75%), if the float rod fault early warning signal is not released yet, step S105 is executed, the air pressure of the air chamber of the jigger is reduced by reducing the opening of the air valve, the air volume input into the jigger is reduced, and the amplitude of the flow vibration of the bed layer in the jigger is reduced to reduce the thickness of the bed layer. Similarly, since the opening degree of the air valve cannot be infinitely reduced, if the opening degree of the air valve is reduced to the threshold value of the opening degree of the air valve (for example, the threshold value of the opening degree of the air valve is set to 85%), if the float rod fault early warning signal is still not released, it is determined that the float rod fault is not caused by the excessively thick bed layer, step S108 is executed to trigger the fault shutdown, and the staff performs maintenance.
Wherein, the adjustment to discharge flashboard aperture and blast gate aperture all adjusts step by step within the settlement time to avoid the sudden change of bed thickness, influence the coal dressing quality.
According to the embodiment of the application, when the floating rod fault early warning signal is received, the fault caused by excessive material quantity is automatically solved by reducing the thickness of the bed layer, and the fault shutdown is triggered when the fault cannot be solved, so that most of the floating rod faults can be automatically solved, and the labor amount of workers is reduced; and bed thickness is adjusted by adopting two modes of increasing the opening of the discharge gate and reducing the opening of the air valve, so that the reduction of the bed thickness can be ensured, and the misjudgment of fault shutdown is avoided.
In one embodiment, the controlling the opening of the discharge gate plate to increase step by step further comprises:
acquiring the thickness of a real-time bed layer;
and if the reduction of the thickness of the real-time bed layer in the first preset adjusting time period is smaller than the first preset variable quantity, triggering fault shutdown.
Generally, increasing the opening of the discharge gate inevitably increases the discharge velocity, and the velocity of decrease in the bed thickness also increases. This application embodiment is when control row material flashboard aperture increases, monitors real-time bed thickness, if in first preset adjustment period, the decrement of real-time bed thickness is less than first preset variable quantity, then explains the aperture regulation inoperative to row material flashboard, probably has row material flashboard trouble, triggers the breakdown this moment and shuts down, overhauls by the staff.
Specifically, the first preset adjustment time period is counted from when the opening degree of the discharge gate is adjusted, the first preset variation may be determined according to the current gate opening degree, and the larger the current gate opening degree is, the larger the first preset variation is.
This application embodiment is when adjusting discharge flashboard aperture, and whether the regulation of discharge flashboard aperture is effective through the decrement judgement discharge flashboard aperture that detects bed thickness to judge whether the discharge flashboard breaks down.
In one embodiment, the controlling the opening of the discharge gate plate to increase step by step specifically includes:
controlling the opening of the discharge gate plate to increase by a first preset opening;
and after waiting for a first preset stable time period, if the opening of the discharge gate plate is smaller than the gate plate opening threshold value and the floating rod fault early warning signal is not released, returning to the previous step.
Specifically, the opening of the discharge gate plate is adjusted in a step-by-step increasing mode, for example, when the first preset opening is 5% and the first preset stable time period is 5min, the opening of the discharge gate plate is controlled to be increased by 5% each time, then the waiting time is 5min, if the opening of the discharge gate plate is smaller than the gate opening threshold value and the floating rod fault early warning signal is not yet removed, the opening of the discharge gate plate is controlled to be increased by 5% again, and after the waiting time is 5min again, whether the opening of the discharge gate plate and the floating rod fault early warning signal are removed … … or not is judged until the floating rod fault early warning signal is removed, the floating rod fault processing method is exited, or the opening of the discharge gate plate is greater than or equal to the gate opening threshold value, and the step of adjusting the opening of the air valve is executed.
This application embodiment adopts the mode adjustment that increases step by step to arrange the material flashboard aperture, adjusts the flashboard aperture at every turn after, waits for adjustment once more after the first predetermined stable time period, provides sufficient stability time, avoids arranging the sudden change by a wide margin of material flashboard aperture and influences the coal dressing quality.
In one embodiment, the method further includes, while the controlling the opening degree of the air valve decreases step by step:
acquiring the thickness of a real-time bed layer;
and if the reduction of the thickness of the real-time bed layer in a second preset adjusting time period is smaller than a second preset variable quantity, triggering fault shutdown.
Generally speaking, reducing the blast gate aperture inevitably makes the rate of change of bed thickness increase, and this application embodiment is when controlling the blast gate aperture and reducing, monitors real-time bed thickness, if in second preset regulation duration, the decrement of real-time bed thickness is less than the second and predetermines the change volume, then explains the regulation of blast gate aperture inoperative, probably has rotatory blast gate trouble, triggers the fault shutdown this moment, overhauls by the staff.
Specifically, the second preset adjustment time period is counted from when the opening degree of the air valve is adjusted, and the second preset variation may be determined according to the current opening degree of the air valve.
When the opening of the air valve is adjusted, whether the adjustment of the opening of the air valve is effective or not is judged by detecting the reduction of the thickness of the bed layer, so that whether the rotary air valve breaks down or not is judged.
In one embodiment, the step of controlling the opening degree of the air valve to decrease includes:
controlling the opening degree of the air valve to reduce by a second preset opening degree;
and after waiting for a second preset stable time period, if the opening degree of the air valve is greater than the opening degree threshold value of the air valve and the fault early warning signal of the floating rod is not released, returning to the previous step.
Specifically, the opening degree of the air valve is adjusted in a step-by-step reduction mode, for example, the second preset opening degree is 1% and the second preset stable time period is 5min, the opening degree of the air valve is controlled to be reduced by 1% each time, then the waiting time is 5min, if the opening degree of the air valve is smaller than the opening degree threshold value of the air valve and the floating rod fault early warning signal is not released, the opening degree of the air valve is controlled to be reduced by 1% again, after the waiting time is 5min again, whether the opening degree of the air valve and the floating rod fault early warning signal are released … … is judged until the floating rod fault early warning signal is released, the floating rod fault processing method is quitted, or the opening degree of the air valve is smaller than or equal to the opening degree threshold value of the air valve, and the fault shutdown step is executed.
The embodiment of the application adopts the mode that reduces step by step to adjust the air valve aperture, adjusts the air valve aperture at every turn, waits for the second to predetermine the adjustment once more after the stable time period, provides sufficient stable time, avoids the big amplitude jump of air valve aperture to influence the coal dressing quality.
In one embodiment, before responding to the float rod fault warning signal, the method further comprises the following steps:
acquiring the height of a floating rod;
and if the height of the floating rod is out of the preset height range, sending a floating rod fault early warning signal.
According to the embodiment of the application, the floating rod fault early warning is carried out through the height of the floating rod, the preset height range of the floating rod during normal work is determined according to actual installation conditions, the preset height range comprises the upper limit height and the lower limit height, when the floating rod is between the upper limit height and the lower limit height, the floating rod is considered to normally run, and when the height of the floating rod is higher than the upper limit height or lower than the lower limit height, a floating rod fault early warning signal is sent out.
