Weighing coal feeder is a completely closed structure, which is an essential weighing coal feeding equipment in coal factory. It can feed coal continuously and evenly, and has the characteristics of pressure resistance, energy saving and environmental protection. It is an ideal equipment for balancing coal consumption at present. Because of the special working conditions, often occur belt deviation, belt slip or coal break and other small faults, how should be solved?

1, weighing coal feeder belt deviation. Coal feeder contains belt anti-deviation device and deviation switch, when the fault occurs, press the deviation switch, and then immediately stop the coal feeder, timely maintenance and treatment.

2. The belt of the weighing coal feeder slips. This situation shows that the belt stops when it goes, which will seriously affect the boiler parameters. The common reason is that the belt tension adjustment of the coal feeder is improper and the water vapor inside the coal feeder is caused, which needs to be stopped immediately.

3. Coal feeder breaks coal. In the event of coal breaking, the belt will send out a coal free signal and automatically trip. Stop the machine to check the raw coal bridge in the coal hopper. If the coal seam of the equipment belt is thin or the flow is interrupted, the coal-free switch baffle will fall and the switch will act. Treatment of coal bucket bridge can be redistributed coal.
