Description
Technical field
This utility model is related to the smelting equipment of copper, especially a kind of flame furnace of fusing blister copper.
Background technology
In copper smelt industry production, traditional smelting process of blister copper is that cold conditions blister copper is added fixed sun with charging vehicle
Pole stove, i.e. " charging operation "；Then with the combustor burns fuel of anode furnace, blister copper is heated, until blister copper all melts
Chemical conversion copper liquid, the process are " fusing operation ".Burner uses gas fuel.Due to the thermal efficiency of fixed anode furnace it is low,
Generally 15%, cause the gas consumption for melting operation high, generally 80 ~ 90Nm3Natural gas/ton copper, the daily output are low, typically
For 120 tons, a stove long the production cycle, 24-36 hours/stove.On the other hand, the charging operation of traditional handicraft is made for semi-mechanization
Industry, needs manually and mechanical engagement, and efficiency is low, and the security risk of mechanical wounding is larger.When being mingled with moisture in raw material, water after charging
Tap touches the copper liquid of high temperature, it may occur that " blowing out " accident, the personal injury for causing anode furnace to collapse with operating personnel.
The content of the invention

Yield poorly, the problems such as long the production cycle, there is provided a kind of flame furnace of fusing blister copper.
Concrete scheme of the present utility model is：A kind of flame furnace of fusing blister copper, with vertical body of heater, sets at the top of body of heater
There is feeding section, be provided with charge door, be furnished with outward mechanical lifting feeding device, chimney is provided with above feeding section, in the bottom of body of heater
Multiple burners are provided with, be it is characterized in that：Furnace lining in a, the body of heater is constituted by two sections, and epimere is carborundum furnace lining, and hypomere is
Magnesium chromium matter furnace lining；B, the side of body of heater added with one sealing copper liquid depositing reservoir, be provided with discharging in the bottom sidewall of body of heater
Mouthful, connected with the tail end of copper liquid depositing reservoir by discharging channel, high energy burner is installed on discharging channel, before copper liquid depositing reservoir
End is provided with the external chute of copper outlet, and on the wall of copper liquid depositing reservoir side is provided with skimming gate, and top surface is provided with several intensification burners.
The burner of lower portion of furnace body described in this utility model is 6-9, at the 100-200mm of bottom surface, equal around body of heater
Cloth.
Discharging channel described in this utility model is located at the top of copper liquid depositing reservoir and arranges.
The copper outlet of the depositing reservoir of copper liquid described in this utility model front end is positioned at apart from depositing reservoir bottom surface 120mm above position
Arrangement, and siphon brick is installed at copper outlet.
Skimming gate on the depositing reservoir of copper liquid described in this utility model is arranged positioned at copper liquid depositing reservoir front end side wall.
Top surface in this utility model in copper liquid depositing reservoir is evenly equipped with 3-6 burner along one row of center line, spacing be 400mm～
600mm。
This utility model adopts heat transfer by heat conduction mode, and heat transfer efficiency is high；Combustion product gases energy and blister copper into before flue
Carry out sufficient heat exchange, the thermal efficiency up to 65 ~ 70%.The energy resource consumption of fusing blister copper is 38 Nm3Natural gas/ton copper, relatively passes
System technique reduces 52.5% ~ 57.8%.Production efficiency is improved, and the production cycle shortens, can continuous charging operation.Charging operation is using volume
Charging unit is raised, is Fully-mechanized charging, more traditional semi-mechanization feed way is in hgher efficiency, essentially eliminates charging operation
Security risk.
Main feature and progress of this utility model relative to traditional blister refining stove：
1. the improvement of heat transfer type
The current fixed anode furnace of blister copper handling process, when cold conditions blister copper is melted, is sprayed into into burner hearth by burner
Fuel simultaneously burns, there is provided heat.But the heat needed for the heating fusing of blister copper, only some is from burner flame and blister copper
Directly contact is conduction of heat, and burner flame is reflexed to blister copper by furnace roof, furnace wall and hot gases more importantly
Upper i.e. radiant heat transfer.Therefore, heat transfer type there is a problem of less efficient.
This utility model is the cylindrical furnace erect, and furnace cavity is compact, and heat transfer type when melting blister copper is then with warm
Based on conduction, radiant heat transfer proportion is little.The efficiency of heat transfer type is greatly improved.
2. the improvement for utilizing of flue gas heat
Existing blister copper handling process, during fusing blister copper, the heat produced during burning is remaining after conduction of heat, heat radiation
Part（85%~90%）Into flue gas, but flue gas time of staying in the burner hearth was just discharged into flue, flue gas less than 3 seconds（Temperature 1200
℃）In the amount of heat that contains waste in vain.Therefore, the thermal efficiency of fixed anode furnace is very low, and only 15%.
This utility model burner is arranged on body of heater side lower part, and the heat that fuel combustion is produced is except a part of conduction of heat is to thick
Copper, remaining major part is also into flue gas.Due to being full of blister cake in burner hearth（Referred to as " stock column "）, high-temperature flue gas enter furnace roof flue
Before, first need to flow through whole burner hearth, so as to carry out heat exchange with blister cake stock column comprehensively：Blister copper raw material thus be fully warmed-up,
Before burner flame is touched, temperature is up to 1000 DEG C；And the flue-gas temperature for entering flue is then reduced to 150 DEG C.Therefore, this reality
With the thermal efficiency up to 65 ~ 70% of new fusing blister copper.
3. fume afterheat is utilized
Existing blister copper handling process, to recovered flue gas heat, most viable mode is to install waste heat boiler.Waste heat pot
The construction cost of stove, operating cost are high, and the optimal situation of operation is also only capable of for the thermal efficiency bringing up to 25 ~ 30%（It is once hot
Efficiency+secondary the thermal efficiency）.
During this utility model fusing blister copper, flue-gas temperature only has 150 DEG C, and waste heat is absorbed heat utilization completely by upper strata raw material,
Thus not there are problems that the investment of corresponding waste heat recovery apparatus,.Also save the problem of land seizure.
4. continuous charging mode
Existing blister copper handling process, is intermittent charging mode.Due to can only be from the cleaning door for being installed on side furnace wall（1~
2）Blister copper is added burner hearth by place, is limited by cleaning door size, quantity, position etc., and one time feeding quantity is for up to single furnace output
30%.The production of each heat, need to feed 2 ~ 4 times.During charging, cleaning door need to be opened, 1200 DEG C of high-temperature flue gas are from work
Escape at door, cause the loss of heat.
This utility model feeds from top-feed mouth, 150 DEG C of flue-gas temperature at charge door, thus heat loss is few；Charge door
Cleaning door need not be set, is continuous charging mode.
5. charging " blowing out accident " risk is eliminated
Existing blister copper handling process, if add the raw material of burner hearth not thoroughly to be dried（Or heavy rain is met with transhipment）,
Contact with moisture is in burner hearth during copper water, it is possible to blow out（Moisture rapid vaporization, volume drastically expand, and are then mingled with height
Warm copper water is sprayed to outside burner hearth）, personal security risk is also very high, destroys body of heater when blowing out serious.The accident of blowing out is blister copper production
In it is of common occurrence.
The raw material that this utility model is added, can be by the abundant drying and preheating of high-temperature flue gas to 1000 before copper water is touched
DEG C, fundamentally solve the problems, such as contact with moisture copper water and blow out.
