ABSTRACT:
The carriage of a retracting soot blower has a driven shaft rotatable to move the carriage along a supporting frame to project and retract a lance tube and to simultaneously rotate the lance tube. The driven shaft is driven from a drive shaft powered by a stationary reversible motor. The driven shaft is connected to the drive shaft by a drum and cable assembly including a double drum assembly on the drive shaft, another double drum assembly on the driven shaft, and an idler pulley at the front of the frame. Upon rotation of the drive shaft in one direction the carriage is moved to project the lance tube by a first cable having its opposite end portions wrapped about and secured to drive and driven drums and an intermediate portion trained over the idler pulley. Upon rotation of the drive shaft in the opposite direction, the carriage is moved to retract the lance tube by a second cable having its opposite end portions wrapped about and secured to drive and driven drums.
The present invention relates to soot blowers of the long retracting type for cleaning the heat exchanging surfaces of boilers by discharging a suitable cleaning fluid against such surfaces, and more particularly to such a soot blower having an improved drive mechanism.
