Cylindrical air heater cleaning equipment - has grille with nozzles discharging cleaning medium moving across cylinder axis

摘要

The cleaning equip. is for an air heater having a hollow cylindrical body with lengthwise compartments. It comprises a grille with discharge nozzles for a cleaning medium and movable in a plane at right angles to the axis of the body. A control determines the time for which the grille stays in the working position in relation to a partic. area to be cleaned. Discharge from the nozzles can be arranged to take place during the entire time when the grille is moving during the cleaning operation. Grille movement can be controlled by a rotary cam with a series of humps whose width determines the travel movement, while the intervals between them regulate the times for which it stays in partic. positions.
