Description
Technical field
The utility model is related to casting iron technology field more particularly to a kind of natural gas cupolas.
Background technology
Furnace cupola is a kind of vertical cylindrical shape smelting furnace, is the important equipment of melting iron in Foundry Production, to by cast iron
Block is fused into molten iron.Traditional furnace cupola uses coke as fuel, and casting pig is in direct contact with coke in stove, and is roused from air port
Wind is combustion-supporting, makes casting pig continuous melting.But can make a very bad impression to environment due to the use of coke, low-carbon energy-saving ring is not achieved
The purpose of guarantor does not meet the national conditions of environmental protection.Therefore, to mostly use other melting modes traditional soaring to substitute for many producers at present
Stove, such as gas-fired cupola, gas-fired cupola use gaseous fuel or liquid fuel, safety clean and environmental protection.
China patent CN204478792U discloses a kind of natural gas cupola, and such natural gas cupola is fired by fuel
It burns and generates thermal current, so that Ceramic Balls is overheated, to ensure that furnace charge column thereon is fully warmed-up, furnace charge is fused into molten iron, molten iron
Continued by the gain of heat by being contacted with Ceramic Balls.The equipment needs to support Ceramic Balls using water cooled grating, in process of production water
If black furnace grid damage, leak, water enters in high temperature liquid iron, then can lead to explosion or furnace body rupture, there are more serious
Security risk.
Invention content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of natural gas cupola, using high temperature refractory,
Replace water cooled grating, eliminates safe hidden trouble.
What the purpose of this utility model was realized in：
A kind of natural gas cupola, it includes the furnace body of resistance to material, and the furnace body of resistance to material is from top to bottom divided into feed zone, heating
Section, superheat section and burning zone, are equipped with stove diameter rail 12 between the bringing-up section and superheat section, the stove diameter rail is that high-temp and high-strength is resistance to
Material, the stove diameter rail are multi-pore structure；Several filtering beads are set above the stove diameter rail, and the small filtering is that high temperature is resistance to
Material.
Further, the furnace body of the resistance to material top is equipped with exhaust pipe, and inner wall is surrounded by insulating layer.
Further, it is provided with feed inlet on the feed zone sidewall of the furnace body；The furnace body outer wall of the burning zone is circumferentially uniform
It is distributed neat gas burner, the neat gas burner entrance stretches to the stove of the burning zone with burning piping connection, outlet
Internal portion.
Further, the lower position of the furnace body inner cavity of the burning zone is provided with slag notch, the furnace body of opposite slag notch
Inner cavity is exported equipped with molten iron.
Further, the stove diameter rail is installed using separating flange, and periphery is sealed using high temperature minuteness.
Compared with prior art, the utility model has the beneficial effects that：
A kind of natural gas cupola of the utility model replaces water cooled grating using high temperature refractory, avoids water cooled grating
If the problem of damage can cause explosion or furnace body to rupture, eliminating safe hidden trouble.
