Abstract
A smelt spout cleaner apparatus includes a cleaning head insertable into a smelt spout and movable in a substantially linear path along the smelt spout for thoroughly cleaning the spout. The cleaning head is mounted on one end of a substantially horizontal beam, the opposite end of which is supported in cantilever fashion to a support base which is selectably movable. The support base includes means for longitudinally translating the beam and causing the cleaning head to move in a linear path along the length of the smelt spout.
Claims36
Apparatus for automatically cleaning a smelt spout of a chemical recovery furnace, said apparatus comprising:
- a cleaning head insertable into said smelt spout for movement there along to dislodge obstructions therefrom;
- an elongated beam for carrying said cleaning head at a forward end thereof;
- and
- a support base for said beam located remotely along said beam from said cleaning head, said base supporting said beam and cleaning head;
- said support base including means for longitudinally translating said beam in a path for moving said cleaning head toward said smelt spout and along a length of said smelt spout and for then retracting said cleaning head to a position rearwardly above said smelt spout,
- wherein said means for longitudinally translating said beam includes a camming track positioned on said support base, said beam including follower means engageable with said camming track, and an actuating means for selectively applying force to said beam in a direction longitudinal of said beam.
Apparatus for automatically cleaning a smelt spout of a chemical recovery furnace, said apparatus comprising:
- a cleaning head insertable into said smelt spout for movement there along to dislodge obstructions therefrom;
- an elongated beam for carrying said cleaning head at a forward end thereof;
- and
- a support base for said beam located remotely along said beam from said cleaning head, said base supporting said beam and cleaning head;
- said support base including means for longitudinally translating said beam in a path for moving said cleaning head toward said smelt spout and along a length of said smelt spout and for then retracting said cleaning head to a position rearwardly above said smelt spout,
- wherein said cleaning head further comprises a heating means for heating at least a portion of said cleaning head for assisting in melting of smelt in the smelt spout.
Apparatus for automatically cleaning a smelt spout of a chemical recovery furnace wherein said smelt spout is disposed at an angle to the horizontal whereby smelt can be poured therefrom, said apparatus comprising:
- a cleaning head insertable into said smelt spout for movement there along to dislodge obstructions therefrom;
- and
- means for longitudinally translating said cleaning head toward and along a length of said smelt spout and for then retracting said cleaning head,
- said means for longitudinally translating said cleaning head comprising guide means, follower means engageable with said guide means, and actuating means for selectively applying force to said follower means for moving said cleaning head along said smelt spout,
- wherein said guide means has a first portion disposed in substantially parallel relation to said smelt spout for enabling said cleaning head to move linearly along said smelt spout,
- wherein said guide means has a second portion angularly related to said first portion for enabling said cleaning head to upraise from said smelt spout to a retracted position.
Apparatus for automatically cleaning a smelt spout of a chemical recovery furnace wherein said smelt spout is disposed at an angle to the horizontal whereby smelt can be poured therefrom, said apparatus comprising:
- a cleaning head insertable into said smelt spout for movement there along to dislodge obstructions therefrom;
- and
- means for longitudinally translating said cleaning head toward and along a length of said smelt spout and for then retracting said cleaning head,
- said means for longitudinally translating said cleaning head including guide means, follower means engageable with said guide means, and actuating means for selectively applying force to said follower means for moving said cleaning head along said smelt spout,
- wherein said cleaning head comprises a heating means for heating at least a portion of said cleaning head for assisting in melting of smelt in the smelt spout.
Apparatus for automatically cleaning a smelt spout of a chemical recovery furnace, said apparatus comprising:
- a cleaning head insertable into said smelt spout for movement therealong to dislodge obstructions therefrom;
- a drive motor carrying said cleaning head therebelow;
- a support beam extending along a portion above said smelt spout and extending a distance beyond the pouring end of said smelt spout, for supporting said drive motor and cleaning head,
- whereby cleaning of said smelt spout is effected by said drive motor moving said drive motor and said cleaning head along a length of said support beam, thereby moving said cleaning head along the portion of said smelt spout.
An apparatus for cleaning a spout of a chemical recovery furnace, comprising:
- an extensible cleaning arm;
- a base portion pivotally supporting said cleaning arm;
- and
- drive means for extending and retracting said extensible cleaning arm,
- wherein said base portion further comprises a guide means and a follower means, wherein said guide means includes a flared portion such that, during extension, said follower means leaves said guide means and upon retraction, said follower means re-enters said guide means at said flared portion thereof.
