Description

Technical Field

[0001] The utility model relates to the technical field of coal feeders, in particular to a device for preventing coal overflow from a coal feeder in a coal bunker. Background Art

[0002] Due to the fluctuations in the coal supply market, there are many uncertainties in the mining and purchase of coal, resulting in a large number of coal samples and mixed coal quality in the coal yard of the power plant. In the process of transporting coal, the thermal power plant first loads the coal from the coal yard to the coal bunker through the conveyor belt, and then relies on gravity to fall onto the coal feeding belt in the coal bunker. In the process of dropping coal from the coal bunker to the coal feeding belt, due to the high viscosity of some coal, it is easy to hang on the walls of the coal bunker, which will block the passage from the coal to the coal feeder after aggravation, causing coal shortage. If the coal shortage cannot be handled and restored in time, it will seriously affect the combustion stability of the boiler and is not conducive to the safe and stable operation of the unit.

[0003] The current method to prevent coal bunker blockage is to send a special person to wait next to the coal bunker. When the monitoring personnel find that the coal is out of coal, they will notify the special person to use a sledgehammer to hit the coal bunker several times, and make the coal fall into the coal feeder through vibration. However, handling it when the coal is out of coal will affect the efficiency of coal transportation and waste human resources. In summary, it is necessary to propose to achieve early prevention instead of handling it when the coal is out of coal, while reducing human labor and saving labor costs to solve the above technical problems.
