The above-described specific meanings belonging to the present application are understood as appropriate by those of ordinary skill in the art.
The method for processing the faults of the float 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 step S102;
step S102: controlling the opening of the discharge flashboard to be gradually increased;
step S103: if the floating rod fault early warning signal is not released, executing step S104;
step S104: if the opening of the discharge flashboard is the flashboard opening threshold value, executing the step S105, otherwise, returning to the step S102;
step S105: controlling the opening 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 step S108, otherwise returning to step S105;
step S108: triggering a fault shutdown.
Specifically, a floating rod detection device can be arranged to detect the floating rod, and the floating rod detection device sends out a floating rod fault early warning signal when the floating rod is considered to be faulty. In general, the reason that the floating rod breaks down is that the bed thickness in the jigging chamber is too thick, and excessive material quantity leads to the floating rod to be unable to act, and this kind of trouble can be got rid of through reducing the material, reduces the bed thickness.
In the embodiment of the present application, step S102 is executed when a float rod fault early warning signal is received, and the opening degree of the discharge gate is controlled to be increased step by step, so as to increase the discharge amount and reduce the bed thickness. Since the opening of the discharge gate cannot be infinitely increased, when the opening of the discharge gate reaches the gate opening threshold (for example, the gate opening threshold is set to 75%), if the float rod fault early warning signal is not released, step S105 is performed, the air pressure of the air chamber of the jigger is reduced by reducing the opening of the air valve, the air quantity input into the jigging chamber is reduced, and the vibration amplitude of the water flow of the bed in the jigging chamber is reduced to reduce the thickness of the bed. Similarly, if the air valve opening cannot be reduced infinitely, if the air valve opening is reduced to the air valve opening threshold (for example, the air valve opening threshold is set to 85%), if the float fault early warning signal is not released, it is considered that the float fault is not caused by the too thick bed layer thickness, step S108 is executed to trigger a fault shutdown, and the operator overhauls the air valve.
The opening of the discharge gate and the opening of the air valve are adjusted step by step in set time, so that abrupt changes of the thickness of a bed layer are avoided, and coal dressing quality is influenced.
According to the embodiment of the application, when the floating rod fault early warning signal is received, the faults caused by excessive material quantity are automatically solved by reducing the bed thickness, and the fault shutdown is triggered when the faults cannot be solved, so that most floating rod faults can be automatically solved, and the labor capacity of staff is reduced; and the bed thickness is adjusted by adopting two modes of increasing the opening of the discharge flashboard and reducing the opening of the air valve, so that the reduction of the bed thickness can be ensured, and the erroneous judgment of fault shutdown is avoided.
In one embodiment, the controlling the opening of the discharge gate to be gradually increased further includes:
acquiring the thickness of a real-time bed layer;
and if the reduction of the real-time bed thickness in the first preset adjustment time period is smaller than the first preset variation, triggering a fault shutdown.
In general, increasing the opening of the discharge gate inevitably increases the discharge speed, and the reduction speed of the bed thickness increases. According to the embodiment of the application, when the opening degree of the discharge gate is controlled to be increased, the thickness of the real-time bed layer is monitored, if the reduction of the thickness of the real-time bed layer is smaller than the first preset variation in the first preset regulation time period, the condition that the opening degree regulation of the discharge gate is not effective is explained, the fault of the discharge gate is likely to exist, the fault is triggered to stop at the moment, and the maintenance is performed by staff.
Specifically, the first preset adjustment period starts to be timed from the time of adjusting the opening of the discharge gate, and the first preset variation can be determined according to the current opening of the gate, and the larger the current opening of the gate is, the larger the first preset variation is.
According to the embodiment of the application, when the opening degree of the discharge flashboard is adjusted, whether the adjustment of the opening degree of the discharge flashboard is effective or not is judged by detecting the reduction of the thickness of the bed layer, so that whether the discharge flashboard fails or not is judged.
In one embodiment, the controlling the opening of the discharge gate to be increased step by step specifically includes:
controlling the opening of the discharge flashboard to increase a first preset opening;
and after waiting for the first preset stable time period, if the opening degree of the discharging flashboard is smaller than the threshold value of the opening degree of the flashboard and the floating rod fault early-warning signal is not released yet, returning to the previous step.
Specifically, the opening degree of the discharge gate is adjusted in a step-by-step increasing manner, taking the first preset opening degree as 5% and the first preset stabilization time period as 5min as an example, controlling the opening degree of the discharge gate to increase by 5% each time, waiting for 5min, controlling the opening degree of the discharge gate to increase by 5% again if the opening degree of the discharge gate is smaller than the gate opening degree threshold value and the float rod fault early warning signal is not released, judging whether the opening degree of the discharge gate and the float rod fault early warning signal are released … … until the float rod fault early warning signal is released, exiting the float rod fault processing method, or executing the step of adjusting the opening degree of the air valve if the opening degree of the discharge gate is larger than or equal to the gate opening degree threshold value.
According to the embodiment of the application, the opening degree of the discharging flashboard is adjusted in a step-by-step increasing mode, after the opening degree of the flashboard is adjusted each time, the discharging flashboard is adjusted again after waiting for the first preset stabilization time period, enough stabilization time is provided, and the influence on coal dressing quality due to large-amplitude abrupt change of the opening degree of the discharging flashboard is avoided.
In one embodiment, the step-by-step reduction of the opening of the control damper further includes:
acquiring the thickness of a real-time bed layer;
and if the reduction of the real-time bed thickness in the second preset adjustment time period is smaller than the second preset variation, triggering a fault shutdown.
In general, reducing the opening of the air valve necessarily increases the change rate of the bed layer thickness, and in the embodiment of the present application, when controlling the opening of the air valve to reduce, the real-time bed layer thickness is monitored, if the reduction of the real-time bed layer thickness is smaller than the second preset change amount in the second preset adjustment time period, it is indicated that the adjustment of the opening of the air valve is not effective, and there is a possibility that a rotary air valve fault exists, and at this time, a fault shutdown is triggered, and the operator overhauls the system.
Specifically, the second preset adjustment period starts to be counted from the time of adjusting the opening degree of the damper, and the second preset variation amount may be determined according to the current opening degree of the damper.
According to the embodiment of the application, when the opening degree of the air valve is regulated, whether the regulation of the opening degree 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 fails or not is judged.
In one embodiment, the step-by-step decrease of the opening of the control damper specifically includes:
controlling the opening degree of the air valve to reduce a second preset opening degree;
and after waiting for a second preset stable time period, if the opening of the air valve is larger than the opening threshold value of the air valve and the floating rod fault early-warning signal is not released, returning to the previous step.
Specifically, the opening of the air valve is adjusted in a step-by-step reduction mode, taking the second preset opening as 1% and the second preset stabilization time period as 5min as an example, controlling the opening of the air valve to be reduced by 1% each time, waiting for 5min, if the opening of the air valve is smaller than the opening threshold of the air valve and the float rod fault early warning signal is not released, controlling the opening of the air valve to be reduced by 1% again, waiting for 5min again, judging whether the opening of the air valve and the float rod fault early warning signal are released … … until the float rod fault early warning signal is released, exiting the float rod fault processing method, or if the opening of the air valve is smaller than or equal to the opening threshold of the air valve, and executing a fault shutdown step.
According to the embodiment of the application, the air valve opening is adjusted in a stepwise reduced mode, after the air valve opening is adjusted every time, the air valve is adjusted again after waiting for the second preset stabilization time period, enough stabilization time is provided, and the influence on coal dressing quality caused by large-amplitude mutation of the air valve opening is avoided.
In one embodiment, before responding to the floating rod fault early warning signal, the method further comprises:
acquiring the height of a floating rod;
and if the height of the floating rod is out of the preset height range, sending out 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 normal working of the floating rod is determined according to the actual installation condition, the preset height range comprises an upper limit height and a 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 operate, 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.
