Abstract
Removable apparatus for cleaning obstructions such as oxidized or encrusted smelt from a smelt spout of a chemical recovery furnace. A metal cleaning head having a rod-like shape depends, at rest, from a housing attached exteriorly of the furnace above the smelt spout. Periodically, an actuating mechanism in the housing moves the cleaning head downward and inward into the smelt spout to dislodge any obstructions that may have accumulated therein, and subsequently retracts the cleaning head to the at-rest position. Channel scraping members attached to the cleaning head are hinged to retract upon insertion of the cleaning head into the smelt spout an extend into the smelt spout channel to urge obstructions out of the channel when the cleaning head is retracted.
Claims20
Apparatus for automatically cleaning a smelt spout of a chemical recovery furnace, comprising:
- a cleaning head insertable in said smelt spout for dislodging obstructions therein,
- actuating means for inserting said cleaning head into said smelt spout and subsequently retracting said cleaning head from said smelt spout, and
- means mountable adjacent to said smelt spout for housing said actuating means.
Apparatus for automatically cleaning a smelt spout of a chemical recovery furnace, comprising:
- a housing affixed adjacent to said smelt spout;
- an actuating mechanism substantially inside said housing;
- and
- a cleaning head attached to said actuating mechanism in a retracted position outside said smelt spout so as not to impede normal flow of smelt from said smelt spout, said actuating mechanism being operable to insert said cleaning head into said smelt spout to dislodge obstructions therein and to subsequently retract said cleaning head from said smelt spout to said retracted position.
Apparatus for automatically cleaning a smelt spout of a chemical recovery furnace, said smelt spout being of a type including an opening in said furnace and having a channel extending outwardly from said opening exteriorly of said furnace, said apparatus comprising:
- a housing attachable to said furnace above said smelt spout;
- an actuating mechanism substantially inside said housing;
- and
- an elongate cleaning head insertable in said smelt spout and pivotally attached to said actuating mechanism exteriorly of said housing, said cleaning head being held in a retracted position above and outside said smelt spout so as not to impede normal flow of smelt from said smelt spout, said actuating mechanism being operable to swing said cleaning head downward and inward into said smelt spout to dislodge obstructions therein and to subsequently retract said cleaning head from said smelt spout to said retracted position.
