Claims
- 1. An anode furnace for receiving blister copper and refining the same to produce copper of higher quality, said anode furnace comprising:
- a cylindrical furnace body having a shell portion and a pair of end plates mounted on opposite ends thereof, said furnace body having an axis and being arranged rotatably with said axis being extended horizontally;
- heating means attached to said furnace body for maintaining an interior of the furnace at elevated temperature; and
- a drive assembly attached to said furnace body for rotating said furnace body between a blister copper-receiving position and a refining position,
- said shell portion having an opening for receiving blister copper, said opening extending circumferentially of said shell portion and arranged such that said opening is directed upwards both in said blister copper-receiving position and said refining position.
- 2. An anode furnace as recited in claim 1, further comprising an exhaust duct having a hood for discharging exhaust gas therethrough, said hood being arranged so as to cover said opening in relation to a prescribed rotational range of said furnace body, whereby said opening for receiving blister copper serves as an outlet for exhaust gas.
- 3. An anode furnace as recited in claim 1, further comprising launder means for introducing the blister copper into said furnace body through said opening, said launder means including an end portion located above said opening of said furnace body and having a water-cooling jacket provided on said end portion.
- 4. An apparatus for refining blister copper discharged from a converting furnace, comprising a plurality of anode furnaces, each of said anode furnaces including
- a cylindrical furnace body having a shell portion and a pair of end plates mounted on opposite ends thereof, said furnace body having an axis and being arranged rotatably with said axis being extended horizontally;
- heating means attached to said furnace body for maintaining an interior of the furnace at elevated temperature; and
- a drive assembly attached to said furnace body for rotating said furnace body between a blister copper-receiving position and a refining position,
- said shell portion having an opening for receiving blister copper, said opening extending circumferentially of said shell portion and arranged such that said opening is directed upwards both in said blister copper receiving position and said refining position, and
- wherein said plurality of anode furnaces are disposed parallel to one another with one end of each anode furnace being directed toward said converting furnace while the shell portions of adjacent anode furnaces are opposed to each other.
- 5. An anode furnace as claimed in claim 1, wherein said furnace body consists of a single chamber.
- 6. An apparatus as claimed in claim 4, wherein said furnace body consists of a single chamber.
- 7. An anode furnace as claimed in claim 1, wherein said shell further comprises a tap hole for discharging said copper of higher quality.
- 8. An apparatus as claimed in claim 4, wherein said shell further comprises a tap hole for discharging said copper of higher quality.
- 9. An apparatus as claimed in claim 7, wherein said shell further comprises at least one tuyere for blowing air or oxygen-enriched air into the furnace body, said at least one tuyere arranged in opposite relation to said tap hole.
- 10. An apparatus as claimed in claim 8, wherein said shell further comprises at least one tuyere for blowing air or oxygen-enriched air into the furnace body, said at least one tuyere arranged in opposite relation to said tap hole.
- 11. An anode furnace as claimed in claim 1, wherein said heating means are attached to an end plate of said furnace body.
- 12. An apparatus as claimed in claim 4, wherein said heating means are attached to an end plate of said anode furnace.
