Fig. 2 is the A-A profile of Fig. 1.
Embodiment of the present utility model is as follows:
On solid fuel heat-treatment furnace base plate (14), with combustion chamber (first), heating clamber (second) and fume extractor (third) one are built by laying bricks or stones with refractory material.One side wall body of (first) installation coal burning machine (1) is not built in the combustion chamber, leave coal burning machine (1) installing space.Build one deck heat-insulation layer at the peripheral of heating clamber (second) body of wall more, and reserve the position of fire door (33).When building combustion chamber (first) body of wall by laying bricks or stones, be with shoot door (30), cleanout door (31), lighting door (27) observation door (25), air inlet (3), (4), (5), (6), secondary wind inleting tube (26) is built by laying bricks or stones in body of wall.For the higher combustion chamber of serviceability temperature, dilatation joint can be set.Top, combustion chamber (first) is built vault by laying bricks or stones with refractory brick.The top that wall with flues (23) and flame jet (21) are blocked in reversal of the natural order of things is built into arch.Rear arch chamber (22) is built the globulate vault by laying bricks or stones, and face arch chamber (24) build into the spherical vault of two different curvature radius by laying bricks or stones, after vault refractory brick finishes building, and the shop asbestic blanket, the building heat insulation layer is filled asbestos plaster above again.
Firebreak (20) and the same heating clamber of smoke-discharging wall (10) (second) body of wall are built by laying bricks or stones together.Firebreak (20) is built by laying bricks or stones and is reached requirement when height, the pour concrete beam (18) that overdoes, and smoke-discharging wall (10) is built heating clamber (second) vault by laying bricks or stones.Heating clamber (second) top is built the arc vault by laying bricks or stones with refractory brick, the shop asbestic blanket, and the building heat insulation layer is filled asbestos plaster above again.To leave thermometer hole (17) when building by laying bricks or stones, and load onto thermocouple (16).
After combustion chamber (first) and heating clamber (second) puzzled, metal casing (34) can be equipped with in the surface.Fire door (33) outer surface is a metal casing, in be lined with refractory brick.Fire door (33) can make heating clamber (second) sealing and open.
After flue (12) and smokestack base (13) puzzle, after smokestack base (13) go up to be installed chimney (15), treated the masonry drying, coal burning machine (1) is packed in the combustion chamber (first), carrying out sealing can come into operation by baker.
When using solid fuel heat-treatment furnace, each air inlet (pipe) and blower fan pipeline are linked, connect thermocouple and each power supply.Workpiece (8) is from fire door (33) pack into heating clamber (second) and closed furnace door (33).By the coal bunker coal, light raw coal from lighting door (27).Along with coal burning machine fire grate (2) running, coal sinks in coal bunker (29) on fire grate (2), coal bunker baffle plate (28) control coal seam thickness, after initiate coal enters the combustion chamber, be subjected to the radiation heating of the interior thermal medium in face arch chamber (24) and coal-fired high-temperature baking, the temperature of coal raises gradually, be contained in the volatilization composition in the coal, to from the solid coal, separate successively,, form the black smoke disperse in face arch chamber (24) with the free carbon mix particles.A small amount of oxygen supply of first air inlet (3) will reach the coal combustion of burning-point, and the burning heat release further improves combustion chamber temperature, a large amount of oxygen supplys of second and third air inlet (4), (5), aggravation burning of coal.The oxygen that secondary wind inleting tube (26) blows into is combustion-supporting for the burning of coal-fired layer upper surface and the flammable composition of disperse from coal-fired top, because it is lower that wall with flues (23) position is blocked in reversal of the natural order of things, force flame to be close to burning of coal face and enter rear arch chamber (22), the heat medium flow that is trapped in face arch chamber (24) and enters rear arch chamber (22) forms vortex flow on sphere arch surface, prolonged in the holdup time of face arch chamber (24), helped flammable composition and fully burn.Enter the heat medium flow of rear arch chamber (22) equally, under the air quantity effect of the 4th air inlet (6), form eddy current circulation for the second time, make the basic after-flame of flammable composition in the furnace gas, black smoke is controlled.Heat medium flow is under the stopping of firebreak (20), produce and slow down and reflection, dust is sunk, pass concrete and overdo the heat medium flow of the reflect flame through hole (19) on the beam (18) under high speed, form eddy current along heating clamber vault surface and jump on workpiece (8), carry out heat exchange, pass firebreak (20) and went up the heat medium flow of fire hole (32), pass workpiece (8) again, flow to smoke-discharging wall (10), enter flue (12) through exhaust smoke hole (9).Because smoke-discharging wall (10) design feature causes heat medium flow to be detained, to slow down, to reach multiple effects such as samming, heat exchange and heavy dirt for a long time in heating clamber (second).Tail gas enters atmosphere through flue (12) and chimney (15), and after workpiece (8) reached heat treatment requirements, blowing out was taken out workpiece (8) from fire door (33), promptly finished heat treatment heating process.
