Description
Technical field
The utility model relates to a kind of with female crucible furnace combustion system burning mouth.
Background technology
At present crucible melting holding furnace (crucible furnace) on the market due to price cheap, therefore burner igniting all adopts the form of self-flare, and its operation principle is as follows; Purge according to burner hearth size, the object purged is to prevent from accumulating too much combustion gas in burner hearth and blasting, purge time is about 30-60 second, namely by YE, combustion air butterfly valve is closed minimum after purging, closed combustion gas to minimum by air-fuel ratio valve, at this moment ignition transformer is energized to ignitor and opens gas electromagnetic valve and lights a fire simultaneously.
When crucible furnace is in melting state, combustor is controlled by fire box temperature, and because burner hearth thermal inertia is less, therefore combustor constantly can be burnt at certain power by temperature controller PID Self-tuning System, and this stage need not light a fire frequently.When aluminium liquid fusing complete go to insulation time, combustor is controlled by temperature of aluminum liquid, but aluminium liquid thermal inertia is very large, cause temperature controller cannot carry out PID Self-tuning System fast, therefore can only take ON-OFF control mode, when temperature of aluminum liquid is lighted a fire lower than during setting value, higher than flame-out during setting value, so just cause combustion system frequently to be lighted a fire, frequent igniting is easy to bring following irreversible shortcoming: take away heats a large amount of in burner hearth during A. furnace purge, very not energy-conservation.B. frequent igniting is easy to the ignitor that weares and teares, and causes cost to increase, the fault of loss of ignition even very easily occurs, had a strong impact on the manufacturing schedule of manufacturer.C. long to the successful time loss of igniting from igniting, be about 40-70 second, show as burning flameout state long and dumb for switching time, therefore temperature of aluminum liquid becomes and is difficult to control.So for temperature equalization, manufacturer requires that electric heating crucible stove generally selected by higher aluminium liquid insulation crucible furnace at present, because electric break-make is very timely, control relatively flexible.But electric heating crucible stove melting ability is less than gas-fired crucible furnace.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is that providing a kind of can realize energy-conservation and longer life with female crucible furnace combustion system burning mouth, avoids frequent igniting and frequently purges burner hearth.
The purpose of this utility model is achieved through the following technical solutions:
A kind of with female crucible furnace combustion system burning mouth, comprise gas source, air blast, fire box temperature meter, temperature of aluminum liquid meter, for export in burner hearth combustion air combustion air YE, burn mouth and main burner for the mother of the mother's fire exporting sustained combustion, air blast is connected with the air intake vent of main burner through combustion air YE, and the air outlet of this air blast also connects female air intake vent burning mouth; Gas source is burnt mouth through mother and is connected with main burner, and gas source is also connected with main burner through air-fuel ratio valve, and temperature of aluminum liquid meter and fire box temperature score electricity Lian Jie combustion air YEs.
Preferably, also comprise gas meter, this gas meter is connected to gas source and mother burns between mouth.
Preferably, also comprise ignition transformer, this ignition transformer is connected to female baked wheaten cake between mouth and main burner.
Compared with prior art, the utility model has following beneficial effect:
1. the mother that the utility model exports female fire burns mouth and once lights a fire successfully and maintain burning always, make this combustion system frequently need not purge burner hearth, equipment becomes more energy-conservation, and the ignitor of main burner need not frequently be lighted a fire, life-span is longer, and the situation of not easily catching fire;
2. the utility model is in conjunction with temperature of aluminum liquid meter and fire box temperature meter, makes temperature of aluminum liquid harmony higher, can be controlled in ± 5 DEG C within, in conjunction with the advantage that combustion gas fusing speed is fast, relative electric heating crucible dissolves holding furnace, has more use advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, gas source; 2, air blast; 3, fire box temperature meter; 4, temperature of aluminum liquid meter; 5, combustion air YE; 6, female baked wheaten cake mouth; 7, main burner; 8, gas meter; 9, ignition transformer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of crucible furnace combustion system with female baked wheaten cake mouth as shown in Figure 1, comprise gas source 1, air blast 2, fire box temperature meter 3, temperature of aluminum liquid meter 4, for export in burner hearth combustion air combustion air YE 5, burn mouth 6 and main burner 7 for the mother of the mother's fire exporting sustained combustion, air blast 2 is connected through the air intake vent of combustion air YE 5 with main burner 7, and the air outlet of this air blast 2 also connects female air intake vent burning mouth 6; Gas source 1 is burnt mouth 6 through mother and is connected with main burner 7, and gas source 1 is also connected with main burner 7 through air-fuel ratio valve, and temperature of aluminum liquid meter 4 and fire box temperature meter 3 are electrically connected combustion air YE 5 respectively.
Female baked wheaten cake mouth 6 is burner, mother burn mouth 6 light a fire success time maintain burning always, main burner 7 is closed when temperature of aluminum liquid exceedes setting value, when temperature of aluminum liquid is lower than setting value, main burner 7 slowly opens combustion air YE 5 and gas source 1, lights rapidly, in about 10 seconds mother under burning the effect of mouth 6, main burner 7 burning and flameout state are switched, fast to ensure the harmony of temperature of aluminum liquid.
Add up gas flow for convenience, this crucible combustion system also comprises gas meter 8, and this gas meter 8 is connected to gas source 1 and mother burns between mouth 6.
For being easier to igniting, this crucible combustion system also comprises ignition transformer 9, and this ignition transformer 9 is connected to female baked wheaten cake between mouth 6 and main burner 7.
Embodiment of the present utility model is not limited thereto; according to foregoing of the present utility model; utilize ordinary technical knowledge and the customary means of this area; do not departing under the utility model above-mentioned basic fundamental thought prerequisite; the utility model can also make the amendment of other various ways, replacement or change, all drops within the utility model rights protection scope.
