UNA DISPOSICION DE ENGRANAJES DE TRANSMISION PARA UN SOPLADOR DE HOLLIN

摘要

The invention is directed to a soot blower for cleaning the interior surfaces of a boiler by discharging a suitable cleaning fluid from a nozzle against such surfaces. The soot blower includes a novel drive system operable both as the horizontal drive for the traveling carriage of the soot blower and as an independently controllable rotary drive for rotating the lance tube of the soot blower. The horizontal drive for the traveling carriage is associated with a motor means whereby operation of the motor means energizes the horizontal drive to advance and retract along a predetermined horizontal path of travel. The rotary drive for rotating the lance tube is mounted on the traveling carriage and is mechanically coupled to the motor means through the horizontal drive whereby operation of the motor provides a driving input for the rotary drive. Pursuant to a significant feature of the invention, the rotary drive includes independent control means for controlling the rotational velocity and direction of the lance tube independently of the speed and direction of travel of the traveling carriage along the predetermined horizontal path of travel.
