Abstract
The utility model relates to a smelting furnace, particularly a smelting furnace with takes moulded coal as fuel. One side of a furnace body is provided with a combustion chamber in which moulded coal is arranged, the end part of the furnace body is provided with a coal inlet and a coal slag outlet, the upper part of the furnace body is provided with a heat gathering plate, and the upper part of the heat gathering plate is provided with a high-temperature cavity which is communicated with a hearth on the other side; the four walls of the combustion chamber are provided with a longitudinal secondary air pipe whose both ends are bent towards the inside of the combustion chamber, and the lower part of the combustion chamber is provided with a track; one end of the coal inlet is provided with a propeller, and the end part of the hearth on the other side is provided with an exhaust passage which is connected with an exhaust funnel. The utility model has advantages that the moulded coal is taken as the fuel, the exhaust of smoke dust can be reduced, environmental pollution can be reduced, the surrounding environment can be altered, and the labour intensity can be reduced.
Description
The utility model relates to a kind of smelting furnace, specifically fusible tin metallurgy ore in sand form, copper ore and be the smelting furnace of fuel with the moulded coal.
At present, known to the people is that tin ore obtains tin slab by reverberatory smelting, and fuel used is high-quality lump coal (calorific value 7, the 000 kilocalorie/kilograms) burning of loosing, and in the fiery storehouse is to adopt cast iron stove strip holder coal, forces to wind combustion-supporting by air blast.Its labour intensity is big, the fuel consumption height, and the thermal efficiency is low, and only about 20%; Last cinder carbon content height reaches about 40%, and raw coal can not fully burn, and causes energy waste big; Dense smoke is emerged with more than 30 meters high chimney, and the Lin Geman index is more than 4 grades, and severe contamination air and environment also need be combustion-supporting with air blast, and flue gas is discharged and also needed a cover air-introduced machine cleaner.
The purpose of this utility model is the shortcoming at above-mentioned existence, provides a kind of discharging flue dust few, alleviates environmental pollution, energy-saving tin ore, the copper ore smelting furnace of cancellation smokestack and air blast, air-introduced machine and cleaner.
Technical essential of the present utility model is: body of heater is made up of combustion chamber (21) and burner hearth (17), one side is provided with built in type burning of coal chamber, the end has coal feed point G and cinder outlet C, and heat collector panel (6) is put on top, is that the high temperature chamber communicates with the burner hearth (17) of opposite side on the top of heat collector panel (6); Combustion chamber (21) wall contains to be established two ends and bends towards indoor vertical secondary air channel (14), and bottom, combustion chamber (21) is provided with track (1) (2); Be provided with propeller (25) at coal feed point one end, make moulded coal car (16) enter combustion chamber (21); The end of opposite side burner hearth (17) is provided with the exhaust duct (8) that links to each other with aiutage (9).Locate to establish an adjustment plate (10) at aiutage (9) and can regulate the exhaust flow rate, combustion chamber (21) inwall and burner hearth (17) inwall and arc arch inwall all are built into hard refractory brick.
The utility model has the advantages that: be fuel with the moulded coal, cancel chimney, reduced soot emissions, reduced environmental pollution, environment around having changed, reduce labor intensity, air blast, air-introduced machine and a whole set of cleaner, energy savings are used in cancellation, the stove expense is built in saving, be applicable to the melting of tin ore, copper ore, it is simple in structure, and is easy to utilize.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 1.
Whole stove is outside to be built into for common brick (3), and the centre is heat-insulation layer (4), and stove is outside fastening with section material frame (23).But body of heater integrated stand device is put on the platform.
Its operation principle is:
After moulded coal entered combustion chamber (21) by coal feed point G by coal car (16) from the track, with match firing point fire bed, pyrolysis produced high temperature in five minutes, and through conduction, put coal-fired body, secondary air hole (14) oxygen supply is fully burnt the coal body simultaneously.Fire combustion high temperature chamber in heat collector panel (6) enters arch is fired the interior tin ore of burner hearth and is made it be melt into Xi Shui in tin pot (11), emits from discharge port (18).Material is added by charging aperture (7) or burner hearth (17) both sides fire door, and per 2.5～4 h are put tin once.Residual air is discharged by burner hearth exhaust outlet (9).Advance coal, slag tap and finish by combustion chamber door (22).It is negative pressure that material is fired the state furnace pressure, and temperature is adjusted plate (10) and realized temperature control by thermocouple monitoring.
Provide below the reverberatory furnace of original melting tin ore and smelting furnace Performance Ratio of the present utility model:
| Index subjet | Former smelting furnace | Existing smelting furnace |
| Advance coal | 1 (20 Kg)/10min | 1 (90 Kg)/2h |
| The thermal efficiency | 20％ | 70％ |
| | 4 grades of Lin Geman | 0.1 grade of Lin Geman |
| Power consumption | 50 KW | 1KW |
| The coal calorific value | 7000 Kcal/Kg | 3500～400 Kcal/Kg |
| Manually | 4 | 2 people |
In the accompanying drawing 5 is the observation test hole, and 12,19,20 is refractory brick, and 13 is bearing support, and 15 is moulded coal, and 24 are Heat-insulation layer.
Claims (2)
1. smelting furnace, body of heater comprises burner hearth and combustion chamber, it is characterized in that a side is provided with built in type burning of coal chamber, and the end has coal feed point G and cinder outlet C, heat collector panel (6) is put on top, is that the high temperature chamber communicates with the burner hearth (17) of opposite side on the top of heat collector panel (6); Combustion chamber (21) wall contains to be established two ends and bends towards indoor vertical secondary air channel (14), and bottom, combustion chamber (21) is provided with track (1) (2); Be provided with propeller (25) at coal feed point one end; The end of opposite side burner hearth (17) is provided with the exhaust duct (8) that links to each other with aiutage (9).
