Leakage-proof control system for coal bunker

The invention provides a coal bunker leakage-proof control system, which comprises a main circuit and a control circuit, and is characterized in that the control circuit comprises a power-on circuit, a slip nozzle control circuit and a forced slip nozzle closing circuit; the power connection circuit controls power supply switches of the slip nozzle control circuit and the main circuit; the sliding nozzle control circuit comprises a sliding nozzle opening circuit and a sliding nozzle closing circuit, and a sliding nozzle motor in the main circuit is controlled to rotate forwards or reversely through a contactor contact so as to open or close a sliding nozzle. The forcibly-closed spout circuit provides a path for manually closing the spout when the device is abnormal. Protective measures are set in the main power supply loop and the control loop, and coal leakage caused by magnetic head faults is prevented; a forced closing system is added to prevent the sliding nozzle from being closed due to damage of a limit
