Utility model content
The purpose of this utility model is to solve the problems of the technologies described above and provides a kind of circulating combustion to melt aluminium stove.
For achieving the above object, the utility model adopts following technical scheme:
A kind of circulating combustion melts aluminium stove, comprise and be located at refractory heat-insulating combustion chamber, molten aluminium pond within the walls, combustion chamber, described molten aluminium pond one side is provided with side and just fires chamber, and the waste gas that described combustion chamber, molten aluminium pond and described refractory heat-insulating are provided with between within the walls for combustion chamber, described molten aluminium pond is discharged is introduced the just indoor air-return duct of combustion of described side; Described combustion chamber, molten aluminium pond and described side just fire between chamber and are provided with combustion gas spout, and this combustion gas nozzle is provided with the blast pipe that connects air blast.
Described side is the indoor burning bed that is provided with of combustion just, and described air-return duct communicates with the bottom of described burning bed.
The top that described combustion chamber, molten aluminium pond and described side just fire chamber all adopts camber fire-resistant ring top separate and seal.
Combustion chamber, described molten aluminium pond can be used for the water jacket hermatic door group that aluminium ingot feeds intake after being provided with and opening.
The body of wall of combustion chamber, described molten aluminium pond is built into by refractory brick.
The utility model is compared with traditional reflective stove and gas generator, saves coal-fired consumption, has reduced the content of the sulphur in aluminum melt, has reduced desulfurization dosing, and then has reduced the discharge of waste gas and flue dust, has reduced the pollution to environment; Improved die casting aluminum component quality, reduced percent defective, increased economic efficiency.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the molten aluminium stove of a kind of circulating combustion that the utility model embodiment provides.
The specific embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Shown in Figure 1, a kind of circulating combustion that the figure shows the utility model embodiment provides melts the structure of aluminium stove.For convenience of explanation, only show the part relevant with the utility model embodiment.
Refer to Fig. 1, a kind of circulating combustion melts aluminium stove, comprise the combustion chamber, molten aluminium pond 3 being located in refractory heat-insulating wall 4, combustion chamber, described molten aluminium pond 3 one sides are provided with side and just fire chamber 8, be provided with for the waste gas of the exhaust outlet of combustion chamber, described molten aluminium pond 6 discharges is introduced to described side and just fire the air-return duct 5 in chamber 8 between combustion chamber, described molten aluminium pond 3 and described refractory heat-insulating wall 4; Combustion chamber 3, described molten aluminium pond and described side just fire between chamber 8 and are provided with combustion gas spout 10, and these combustion gas spout 10 places are provided with the blast pipe 11 that connects air blast.
The body of wall 2 of combustion chamber, described molten aluminium pond 3 is built into by refractory brick.
Described side just fires and in chamber 8, is provided with burning bed 7, the air outlet of described air-return duct 5 communicates with the bottom of described burning bed 7, the front end face that described side just fires chamber 8 can add the hermatic door 13 of fuel, the hermatic door 14 that can slag tap after being provided with and opening in described hermatic door 13 belows after being provided with and opening.
Described burning bed 7 forms arrangement by many long iron bars and forms.
Combustion chamber, described molten aluminium pond 3 all adopts camber fire-resistant ring top 9 separate and seal with the top that described side just fires chamber 8.
Combustion chamber, described molten aluminium pond 3 is provided with to open and can be used for the water jacket hermatic door group 12 that aluminium ingot feeds intake.
Further, in the utility model embodiment, the outer stove outer covering 1 that is provided with steel of described refractory heat-insulating wall 2.
During work, the waste gas of introducing with air-return duct 5 on the coal combustion bed 7 in side just fires chamber 8 carries out anoxycausis, produces gas burner, is blown to guide in combustion chamber, molten aluminium pond 3 carry out oxygenation high-temp combustion by the air-flow of blast pipe 11, carries out melting aluminum; The waste gas streams burning is discharged from the exhaust outlet 6 of combustion chamber, molten aluminium pond, and the bottom that again enters burning bed 7 along air-return duct 5 enters side and just fires chamber 8, carries out cold and oxygen deficient burning, thereby produce coal gas and cold flame on coal combustion bed 7; By the air-flow in blast pipe 11 blow draw and oxygenation in combustion chamber, molten aluminium pond 3, carry out the fusing that high-temp combustion completes aluminium; Waste gas is led by thermal expansion force and air-flow, again from air-return duct 5, passes through, and constantly enters successively working cycles.
The utility model is the combustion technology again of utilizing waste gas circulation by changing traditional direct burning and exhausting, reduce soot emissions, utilize coal gas and flame mixed combustion, improve fired coal combustion efficiency, temperature is controlled, reduce the impurity that enters molten aluminium, reduce amount of oxidation, thereby reach, improve aluminium casting quality, realize simultaneously and reduce waste gas waste sludge discharge, improve efficiency of combustion, save the raw-material dual-use functions such as coal and aluminium.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
