Description
Technical field
The utility model relates to a kind of melting furnace, specifically, relates to a kind of pouring molten stove, belongs to the casting pouring field.
Background technology
When making metal casting at present, raw metal need be placed on and carry out heat fused in the melting furnace, pour into a mould then, pass through mould molding.Raw metal heat fused process need temperature is very high, therefore, need constantly heat raw metal, and the fuel that heating is now used mostly is coal or gas greatly, and coal combustion internal heat gas is to produce a large amount of high-temperature flue gas; And traditional processing method to these high-temperature flue gas is exactly to be discharged into after the cooling processing in the atmosphere, and this way makes high-temperature flue gas take away a large amount of heats in discharging, if the heat recovery and utilization in the flue gas just can be able to be saved many fuel.
The utility model content
The purpose of this utility model provide a kind of can be to the flue gas waste heat recovery melting furnace of heat recovery and utilization in the high-temperature flue gas.
The technical solution adopted in the utility model is:
A kind of flue gas waste heat recovery melting furnace, comprise housing, place melting chamber and combustion chamber in the housing, described melting chamber is airtight tubular structure, described melting chamber top sidewall is provided with observation panel, the lower end of described melting chamber places in the combustion chamber, described side wall of combustion chamber is provided with dog-house, the bottom of described combustion chamber is provided with slag-drip opening, all have and observation panel on the described housing, dog-house, corresponding mouthful of slag-drip opening, described inner walls is provided with refractory insulating layer, this refractory insulating layer closely contacts with the outer wall of combustion chamber, form the circuitous chamber of flue gas between described refractory insulating layer and melting chamber, described case top is provided with the chimney that passes refractory insulating layer and be communicated with the circuitous chamber of flue gas, the top of described combustion chamber is provided with the circuitous pipeline of flue gas, this pipeline is wrapped on the outer wall of melting chamber, and the circuitous pipeline of described flue gas is communicated with the circuitous chamber of flue gas.
Further, be connected with air blast on the described combustion chamber.
Form the circuitous chamber of flue gas between type refractory insulating layer that this practicality is new and melting chamber, the circuitous chamber of this flue gas is communicated with the circuitous pipeline of flue gas, the circuitous pipeline of flue gas is wrapped on the outer wall of melting chamber, like this, the high-temperature flue gas that produces in the combustion chamber constantly passes through on the outer wall of melting chamber by the circuitous pipeline of flue gas, the flue gas of high temperature is with the heat transferred melting chamber simultaneously, play melting chamber is incubated, the effect of heating, can improve the melting rate of metal principle in the melting chamber, then, high-temperature flue gas can continue the effect of bringing extra power into play after coming out to enter in the circuitous chamber of flue gas from flue gas pass-over offset road, and the top of melting chamber is heated, insulation; The utility model also is provided with the chimney that passes refractory insulating layer and be communicated with the circuitous chamber of flue gas in case top, and this chimney was brought into play the high-temperature flue gas of effect the most at last and discharged.
The utility model has the advantages that: to heat recovery and utilization in the high-temperature flue gas, energy savings, the utilization rate that improves fuel and the burn-off rate of raw metal.
