Pulse pneumatic coal-bloating resistant device

The utility model relates to a pulse pneumatic coal-bloating resistant device, which is a device for preventing various coal storing bunkers from bloasting coal. The utility model is characterized in that the set of device is positioned at the circumference outside the lower part of the coal storing bunker, and is composed of an air pipeline and an air nozzle. A pulse signal generator is arranged on a main air pipe. When occurring coal bloasting, a coal breaking-off signal switches on the pulse signal generator, and simultaneously, switches on a pulse control air valve, so as to jet a high pressure air flow to a coal bloasting layer, and the arch of the coal bloasting layer can be destroyed, so as to a coal layer is fallen. The utility model has the advantages of simple device, less investment, automatic control, safe operation, worry saving, and labor saving, and is suitable for installation and use for various coal storing bunkers.
