Abstract
462,857. Soot blowers. ATKINS, G. R., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 11, 1935, No. 34410. [Class 99 (ii)] A soot blower, for cleaning the tubular &c. elements of a preheater &c. of the kind in which the elements rotate about a common axis, comprises a nozzle 13 which is transversed radially across the elements by the rotary motion of the preheater itself. The traversing movement of the nozzle is preferably effected by a cam 2 which is located on the preheater casing 1 and engages, once during each revolution of the latter, a roller 3 mounted on an arm 4 which is pivoted at 5 and is subjected to the pressure of a spring 6. The arm 4 carries a pawl 8 for engagement with a ratchet segment 7 which is connected through links 9, 10, 11 with a pipe 12 terminating in the nozzle 13, pressure fluid, e.g. compressed air, being supplied to the pipe 12 by a pipe 14 provided with a control valve 27. At the commencement of blowing, the ratchet 7 is against a stop 16 and the nozzle is at the periphery of the rotor. With each revolution of the preheater the cam 2 first rocks the arm 4 to cause the pawl 8 to ride over a tooth of the ratchet and then permits the spring 6 to rock the arm in the opposite direction, the pawl 8 actuating the ratchet and with it the nozzle tube 12 thus effecting a step-by-step movement of the nozzle towards the axis of the preheater. When the nozzle reaches the end of its travel the air supply is cut off by a weighted lever 21 which is released by a pin 18 carried, by a member 19 on the link 11 through a lever 20. Backward movement of the ratchet during operation of the blower is prevented by a second pawl 29, and during inoperative periods the roller 4 is shifted out of the path of the cam 2 and the pawls 8, 29 away from the ratchet 7 by a hand lever 26.
