The specific embodiment
By Fig. 1 to 3 as can be known, the utility model is made up of reinforced shaft furnace A and burning end stove B, and its reinforced shaft furnace A is arranged on the side of burning end stove B, connect by partition wall hole 1 between two stoves, wherein:
The top of reinforced shaft furnace A is made as charge door 2, the bottom is the platform 3 that absorbs heat with domatic material buffer, the shaft furnace passage 4 that the middle part falls for material, the material that drops into from charge door 2 falls to material buffer heat absorption platform 3 through shaft furnace passage 4, and fully absorbs and flow into burning end stove B after fume afterheat enters the semi-molten state;
Described reinforced shaft furnace A for reinforced passage, had been again an exhaust gases passes both, and exhaust opening 5 is arranged on the top of reinforced shaft furnace A;
Stove B comprises the burner hearth 6 of a sealing at the bottom of the described burning, the aluminium liquid dewatering outlet 7 that communicates with burner hearth, reach the efficiency energy saving burner 8 and the pre-hot-flow flue 9 that materials in the burner hearth 6 are carried out heat fused, described partition wall hole 1 connects and is arranged on burner hearth 6 and reinforced shaft furnace A adjacent.
Charge door 2 described in the utility model is provided with loading hopper 10, and cast iron cover 11 is set on the loading hopper 10, cast iron cover 11 by being arranged on reinforced shaft furnace A one side hoist engine 12 and renovate support 13 and open or close charge door 2.Stove B one side offers fire door 19 at the bottom of the described burning, and burner 8 and relevant valve member are arranged on fire door 19 both sides.Stove B is the circular base stove at the bottom of the described burning, and burning end stove B and reinforced shaft furnace A are connected to form circle and add the half elliptic structure.The furnace wall of described reinforced shaft furnace A and burning end stove B is followed successively by steel plate layer 14, spun-glass insulation carpet veneer 15, light-weight insulating brick layer 16, impervious aggregate layer 17 and high aluminium brick layer 18 from outside to inside.The high liquid level (HLL) 20 of melting materials capable is no more than the radial height in partition wall hole 1 in described reinforced shaft furnace A and the burning end stove B.
Structural principle of the present utility model:
1, adopt circular base stove and rational burner configuration, burner hearth is a circular configuration, and efficiency energy saving burner is arranged along the furnace wall tangential direction, furnace atmosphere circulation is strong, and furnace temperature is even, no hot-spot burn-off phenomenon, can improve the quality of products effectively, prolong stove service life.
2, adopt shaft furnace: furnace charge fully absorbs fume afterheat at shaft furnace passage and material buffer heat absorption platform heat absorption back, reduce the shaft furnace exhaust gas temperature, improve the thermal efficiency greatly, and furnace charge has been preheating to the semi-molten state when entering burner hearth, has guaranteed very high melting rate and lower energy consumption.
