Description
Technical Field
The utility model belongs to the field of metallurgical equipment, especially, relate to a through roaster furnace of precision casting membrane shell.
Background
At present, the shell of a general membrane shell roasting furnace is generally assembled and welded on the outer surface of a furnace wall by adopting steel plates, the temperature of the outer surface of a furnace body is high, and the operation of workers is inconvenient. Meanwhile, the burners on the furnace walls on the two sides of the furnace body are all direct flame burners, so that the injection speed is low, and flame is directly injected onto the film shell, so that the film shell is easy to deform, and the quality of products is influenced. When the furnace enters, the smoke generated by the membrane shell overflows, so that a large amount of smoke in a workshop is lost and cannot be discharged in time, and the furnace body is corroded. Has the problems of high energy consumption, unattractive furnace body, great environmental pollution and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a smart cast membrane shell through roasting furnace that rational in infrastructure, intensification are swift, the temperature is even, it is smooth and easy to discharge fume, energy-concerving and environment-protective, pleasing to the eye high efficiency, membrane shell warp for market, furnace body longe-lived.
The technical scheme of the utility model is that: the furnace comprises a furnace shell, a furnace body, a kiln car, a furnace door, a burner, a smoke exhaust pipeline and the like, wherein the furnace body comprises a furnace wall built by heat-resistant insulating bricks, a furnace top and a metal frame, and insulating burner bricks for mounting burners are arranged on two sides of the furnace wall of a roasting section in a staggered manner. The burner is an intermediate-speed flat flame burner, and the heat-insulating burner block is a flat flame burner block. The furnace shell is a double-layer structure consisting of a furnace outer shell and a furnace inner shell, the furnace outer shell is embedded on the furnace body frame by adopting a baking finish decorative steel plate, and the furnace inner shell is assembled and welded on the outer surface of the furnace body by adopting a steel plate. A smoke suction hood is arranged above the feeding furnace door, an air heat exchanger and a smoke exhaust pipeline are arranged on the furnace top at the furnace outlet end, and the smoke suction hood is connected with the furnace tail smoke exhaust pipeline through a fan and a pipeline.
The utility model has the advantages that: because the medium-speed flat flame burners are arranged on the two sides of the furnace body in a staggered mode, flame is sprayed to the periphery of the burners and is not directly sprayed to the membrane shell, the spraying speed is high, the spraying area is large, and the temperature uniformity of the hearth is better. When entering the car, smoke overflows and is sucked away through the smoke suction hood to enter the furnace tail smoke exhaust system, the smoke generated in the furnace reversely flows to the tail part of the furnace, combustible materials which are not burnt out are combusted again through high temperature at the rear part, and the final smoke enters the dust removal system through the tail smoke exhaust port to be purified. The furnace has the advantages of reasonable structure, rapid temperature rise, uniform temperature, smooth smoke discharge, energy conservation, environmental protection, attractive appearance, high efficiency, small membrane shell deformation, long service life of the furnace body and the like, fundamentally solves the problems of large membrane shell deformation, non-uniform temperature, flameout of burners and the like in the production process, and greatly improves the product quality.
The present invention will be further explained with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic view of the cross-sectional structure of the roasting section of the present invention;
fig. 2 is a schematic view of the main sectional structure of the present invention.
In the figure: the furnace comprises a furnace shell 1, a furnace inner shell 2, a heat-insulating burner brick 3, a burner 4, a kiln car 5, a smoke absorbing hood 6, a feeding furnace door 7, a smoke exhaust pipeline 8 and an air heat exchanger 9.
Detailed Description
As shown in fig. 1 and 2: the precision casting film shell through type roasting furnace comprises a furnace shell, a furnace body, a kiln car, a furnace door, a burner, a smoke exhaust pipeline and the like, wherein the furnace body comprises a furnace wall built by heat-resistant insulating bricks, a furnace top and a metal frame, and insulating burner bricks 3 provided with burners 4 are arranged on two sides of the furnace wall of a roasting section in a staggered mode. The burner 4 is an intermediate-speed flat flame burner, and the heat-insulating burner block 3 is a flat flame burner block. The furnace shell is a double-layer structure consisting of a furnace shell 1 and a furnace inner shell 2, the furnace shell 1 is embedded on a furnace body frame by adopting a baking finish decorative steel plate, and the furnace inner shell 2 is assembled and welded on the outer surface of the furnace body by adopting a steel plate; a stainless steel smoke absorption hood 6 is arranged above the feeding furnace door 7, an air heat exchanger 9 and a smoke exhaust pipeline 8 are arranged on the furnace top at the furnace outlet end, and the smoke absorption hood 6 is connected with the furnace tail smoke exhaust pipeline 8 through a fan and a pipeline. Implement the utility model discloses the time, when opening feed end furnace gate 7, when kiln car 5 will load the smart cast membrane shell above that and send into furnace in, can produce a large amount of flue gases and spill over from furnace gate 7, set up the flue gas suction flow direction stove tail exhaust pipe 8 that will spill over furnace gate 7 under the effect of fan at the stainless steel smoke absorption cover 6 of furnace gate 7 top this moment. When the medium-speed flat flame burner 4 burns, the generated flame is distributed to the periphery of the burner and is not directly sprayed to the membrane shell, so that the heating speed is high, and the temperature is uniform. Meanwhile, smoke generated in the furnace reversely flows to the tail of the furnace under the action of an air heat exchanger 9 arranged at the top of the tail of the furnace, combustible materials which are not burnt out are combusted for two times through high temperature at the rear part, and the final smoke flows to a smoke exhaust pipeline 8 through the air heat exchanger 9 to enter a dust removal system for purification. The furnace has the advantages of reasonable structure, rapid temperature rise, uniform temperature, smooth smoke discharge, energy conservation, environmental protection, attractive appearance, high efficiency, small membrane shell deformation, long service life of the furnace body and the like, fundamentally solves the problems of large membrane shell deformation, non-uniform temperature, flameout of burners and the like in the production process, and greatly improves the product quality.
