Abstract
The invention discloses a crucible furnace with a flue gas recycling device. The crucible furnace comprises a furnace body and a hearth. A heat-insulation layer is arranged between the furnace body and the hearth, a crucible is arranged over the hearth, a chimney is arranged on the top of the hearth and is positioned on a side of the crucible, a U-shaped flue is arranged along the outer edge of the crucible, one end of the U-shaped flue is communicated with the chimney, a flue opening in the other end of the U-shaped flue is parallel to the crucible, an air blower which can blow hot air into the U-shaped flue is arranged at the upper end of the chimney, and a waste bag for collecting impurities is connected to the outer end of the flue opening by a flue pipeline. The crucible furnace has the advantages that generated high-temperature flue gas is blown into the U-shaped flue by the air blower, a heat-insulation effect can be realized for the crucible by the aid of the high-temperature flue gas, the temperature of the high-temperature flue gas is reduced after the high-temperature flue gas flows through the U-shaped flue, the flue gas is exhausted into the air after further flowing through the waste bag, accordingly, environmental pollution can be reduced, and the purpose of protecting environments can be achieved; the heat-insulation layer is arranged between the furnace body and the hearth, so that radiation loss can be reduced, and purposes of raising the efficiency and saving energy can be achieved.
Description
Technical field
The present invention relates to a kind of crucible furnace, especially a kind of crucible furnace with flue gas recovery device.
Background technology
Crucible furnace is the metallurgical firm also equipment of conventional deposite metal; a kind of for melting or the stove of the metal such as Insulating aluminium, lead; generally comprise body of heater, burner hearth and put into the crucible of burner hearth; normally but this is emitted in air the waste gas of the high temperature producing after burning; the heat producing for flue gas does not reach good utilization conventionally; energy consumption consumption is large, and the high-temp waste gas of discharging increased the weight of again the burden of environment, is unfavorable for the protection of environment.
Summary of the invention
In order to address the above problem, the invention provides a kind of crucible furnace with flue gas recovery device that crucible is incubated that high-temperature flue gas is reclaimed.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of crucible furnace with flue gas recovery device, comprise body of heater and burner hearth, in the middle of body of heater and burner hearth, be provided with a heat-insulation layer, directly over burner hearth, be provided with crucible, be provided with chimney in the top of burner hearth, a side of crucible, be provided with U-shaped flue along the outward flange of crucible, one end of U-shaped flue communicates with chimney, and the floss hole of the other end of U-shaped flue is parallel with crucible.
Further improvement of the present invention is: be provided with the air blast that hot blast is blown into U-shaped flue in the upper end of chimney.
Further improvement of the present invention is: floss hole outer end is connected with the waste material bag of a collection impurity by flue pipeline.
Further improvement of the present invention is: be provided with one deck flame retardant coating along the outer wall of U-shaped flue.
Further improvement of the present invention is: heat-insulation layer is aluminosilicate refractory fiber.
The invention has the beneficial effects as follows: the present invention is driven into U-shaped flue by the high-temperature flue gas of generation by air blast, utilize high-temperature flue gas to be incubated crucible, the temperature of the high-temperature flue gas after U-shaped flue has also reduced, be discharged in air by after a waste material bag again, reduce the pollution to environment, reached the object of environmental protection, in the middle of body of heater and burner hearth, be provided with heat-insulation layer, reduce radiation loss, reach energy-efficient object.
The present invention is simple in structure, reasonable in design, easy to operate, and the high-temperature flue gas that utilizes stove to produce is incubated crucible, and energy-conserving and environment-protective make the high insulating effect of crucible, and the time is long.
