Title:
EMERGENCY OPERATING DEVICE USED IN FILTER CLEANING EQUIPMENT
Document Type and Number:
Japanese Patent JPH02163408
Kind Code:
A
Abstract:
PURPOSE:To obtain an emergency operation device which permits the traveling of a vehicle so that an electric control valve arranged in a piping connected with an air tank is opened when a trouble is generated in an electric control circuit of a filter cleaning equipment and blowing air in the reverse direction to the flow of the exhaust gas in a dust collector and cleaning is performed. CONSTITUTION:When the electric control circuit of a filter cleaning equipment 20, e.g., an ordinarily used control unit 24 is broken, the opening/closing operation of a solenoid valve 23 is suspended. Then, an alarm lamp 16 lighted. If the alarm lamp is lighted, a manually operated switch 11 is closed by operating the manually operating switch 11, and then electric current flows in a solenoid coil 34, and the solenoid valve 23 is opened, and a large quantity of the compressed air flows into a cleaning nozzle 21 from an air tank 22 through a piping 33. Therefore, the filter cleaning equipment 20 can be operated by an emergency operating device even in the case when the ordinarily used control unit 24 is broken, and the traveling of a truck is permitted.
