Description
Technical field
The invention belongs to the metallurgical furnace technical field of non-ferrous metal metallurgy industry, the charging knot of more particularly to a kind of anode furnace
Structure.
Background technology
The blister copper melt of continuous converting technique output is generally conveyed into anode refining furnace through chute, anode furnace common at present
Feeding manner mainly has：
(1) a charging aperture is set at the center of anode furnace one end headwall, chute is stretched into body of heater from charging aperture, blister copper melt
Anode furnace is flowed directly into by chute；In the lower section of chute, fuel nozzle is set；Smoke evacuation is set on the other end headwall of anode furnace
Mouthful.
(1) problems be present in feeding manner：Charging aperture is located at the center of headwall, and because space limits, an anode furnace is only
One chute charging can be set, when chute breaks down anode furnace will be caused to stop expecting, and have a strong impact on operating efficiency；Below chute
Burner easily bonds cold copper, and cleaning is difficult, influences the heat insulation effect of chute；Exhaust opening blister copper liquid level in stove is close, easily
Bonding blocks；Charging aperture and exhaust opening are at the center of headwall, thus liquid level must be controlled below body of heater center in stove, blister copper
Delivered payload capability it is small, the capacity utilization of anode furnace is low.
(2) a charging aperture is opened up (on cylinder) on the top of anode furnace one end, a buffering is set above charging aperture
Bag, blister copper flows into buffers packet by chute, then flows into anode furnace by buffers packet；Buffers packet is independently hung, and is not connected with anode furnace,
It is not connected with chute；Buffers packet regularly replaces according to service condition.
(2) problems be present in feeding manner：Buffers packet is set between the charging aperture and chute of anode furnace, adds and slips
Difference in height between groove and anode furnace charging aperture so that continuous-blowing furnace need to increase arrangement, add cost of investment；Need to burn
Substantial amounts of fuel is incubated to buffers packet, and to prevent the blister copper melt in buffers packet from bonding, operating cost is high；Buffers packet needs
Periodic replacement, the operating efficiency of anode furnace is influenceed, and the processing cost of the maintenance cost of buffers packet and discarded buffers packet is high.
The content of the invention
It is an object of the invention to provide a kind of feeding structure of anode furnace, the operating efficiency of anode furnace can be effectively lifted.
To realize object above, the technical solution adopted by the present invention is：A kind of feeding structure of anode furnace, including offer
The body of heater of charging aperture, is covered with petticoat pipe at the charging aperture set on shaft, feed chute through petticoat pipe cover wall to charging aperture at prolong
Stretch and the transporting molten raw material into stove.
Prior art is compared, and the present invention has following technique effect：It is rational in infrastructure, because the setting of petticoat pipe, charging aperture are simultaneous
Tool charging and smoke discharging function, had both lifted the capacity utilization of anode furnace, and effectively avoided exhaust opening from blocking, and greatly improved anode
The processing efficiency of stove；And so cigarette case temperature is higher, it is not required to set burner to protect feed chute in addition in petticoat pipe
Temperature, it is avoided that burner fault impact operating efficiency, moreover it is possible to effectively save energy consumption.
