Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
A kind of built-in accumulation of heat iron-bits melting furnace as shown in Figure 1, including periphery use the body of heater 1 of steel structure support, its
The both sides wall part of middle body of heater 1 is made up of light-weight brick, clay brick, and the top of body of heater 1 is formed using insulation material cast.
There is the melt chamber 2 of fusing iron filings positioned at the center of body of heater 1, the described bottom surface of melt chamber 2 is oblique, to body of heater 1
The charging aperture of interior input iron filings is located at the higher one end in the bottom surface of melt chamber 2, and molten iron outlet is located at the relatively low one end in the bottom surface of melt chamber 2, this
Sample is easy to molten iron to trickle.Prechamber 3, melt chamber 2 and two prechambers 3 are symmetrically arranged with positioned at the left and right sides of melt chamber 2
Connected by entering fiery passage 4, be passed through in the roof of body of heater 1 of each top of prechamber 3 in the oriented prechamber 3 of right angle setting
The breather pipe 5 of natural gas, lamination stack product has absorption, discharges the accumulation of heat of high-temperature flue gas heat in each underlying space of prechamber 3
Ball 6, the wind and smoke road 7 for being equipped with connection prechamber 3, each wind and smoke road 7 are opened in the wall of body of heater 1 of the lower section of heat-storing sphere 6
The air blower and air-introduced machine of peripheral hardware are connected by a three-way diverter valve pipeline, and is handed over by each wind and smoke road 7 of electric control system controls
For connection air-introduced machine or air blower.
The theory of combustion：When cold air is preheated to more than 1000 degree, fuel is i.e. flammable in the case where oxygen concentration is 2%
Burn, reach a high temperature air burning principle, and gas-phase space forms the relatively uniform high temperature intense radiation black matrix of a temperature so that fusing
Stove Heat Transfer in Furnace efficiency is significantly improved.
The course of work is sketched：When originating operation, by igniter burner ignition in the melt chamber 2 of body of heater 1, now left side
Wind and smoke road 7 by reversal valve control connection air blower and close the connection with air-introduced machine, the wind and smoke road 7 on right side is then by reversal valve control
System connects air-introduced machine and closes the connection with air blower, and the temperature of the change iron in melt chamber 2 is up to more than 1550 degree, by air blower
Blast the cold wind entered through left side wind and smoke road 7 and be heated to form high-temperature flue gas, discharged behind the wind and smoke road 7 on right side by air-introduced machine, it is high
For warm flue gas when by the heat-storing sphere 6 on right side, its heat absorbs accumulation of heat by heat-storing sphere 6, and the flue-gas temperature of air-introduced machine discharge can
As little as 200 degree；Afterburner combustion system commutation valve events, air blower is connected into the wind and smoke road 7 on right side, the wind and smoke road 7 in left side connects
Ventilating draught fan, air blower press-in cold air pass through right side heat-storing sphere 6, the heat release of heat-storing sphere 6 by cold air be heated to 1000 degree with
On, with the natural gas that the breather pipe 5 on right side is passed through in the mixed combustion of prechamber 3, thermal-flame enters fusing through entering fiery passage 4
Fusing iron filings in chamber 2, for high-temperature flue gas now when extracting discharge out by the air-introduced machine in left side, the heat-storing sphere 6 in left side absorbs heat
And accumulation of heat；During subsequent cycle, reversal valve acts again, and the wind and smoke road 7 in left side connects air blower, and the wind and smoke road 7 on right side connects
Air-introduced machine, when the cold air of air blower press-in is by the heat-storing sphere 6 in left side, cold air is heated to 1000 degree by the heat release of heat-storing sphere 6
