Abstract
The invention discloses an air-blowing type anti-vortex combustion chamber for a hot-shearing furnace. The air-blowing type anti-vortex combustion chamber comprises a burner, a thermal circulating fan and an air outlet and an air inlet of a furnace body of the hot-shearing furnace, wherein the thermal circulating fan is communicated with the burner through a third air duct and communicated with the air outlet through a first air duct, and the burner is communicated with the air inlet through a second air duct. Hot gases of the low temperature inside the furnace are sucked out upwards and blown to the burner by the thermal circulating fan, so that the gases of the low temperature are mixed with high-temperature gases, pass the air ducts and are blown to aluminium bars inside the furnace to form circulation; and compared with traditional 'air-suction type' circulating modes, the 'air-blowing type' circulating mode has the advantages that the fan is effectively protected and the service life of the fan is prolonged.
Description
Technical field
The present invention relates to a kind of heat circulating system, be specifically related to the anti-turbulence chamber of a kind of bleed type for hot shearing furnace.
Background technology
Be exactly long excellent hot shearing furnace the most usually in hot shearing furnace, long excellent hot shearing furnace is the ineffective activity for aluminium alloy industry old-fashioned stub heating furnace waste material, scheduling of production, and designs novel aluminium bar heating, shearing stove.The combustion chamber of traditional hot shearing furnace is directly connected with the air outlet of body of heater, thermal circulation fan is arranged between combustor and the air inlet of body of heater, because thermal circulation fan directly sucks high-temperature gas in combustion chamber, then be blown in hot shears body of heater, this kind of mode will cause thermal circulation fan directly to suck flame, furnace gas mist, temperature is very high, be easy to the damage causing extension set, reduce service life, and this kind of connected mode, easily cause gas temperature to mix uneven, thus easily cause non-uniform temperature in hot shearing furnace.
Summary of the invention
The object of the invention is to overcome the defect existed in prior art, provide installation easy to operate, security performance is high, and the life-span is long, and air heat uniformity is good, the anti-turbulence chamber of the continuous type bleed type for hot shearing furnace.
For achieving the above object, technical scheme of the present invention there is provided the anti-turbulence chamber of a kind of bleed type for hot shearing furnace, comprise combustor, the thermal circulation fan be connected by the 3rd air channel with described combustor, the air outlet of hot shearing furnace body of heater and air inlet, described thermal circulation fan is connected by the first air channel with air outlet, described combustor is connected by the second air channel with air inlet, the nozzle of described combustor is fixedly installed in the first sleeve, described first sleeve lining is provided with backpitch groove, described first sleeve outer setting has the second sleeve, described second sleeve makes described second air channel be connected with described 3rd air channel.Thermal circulation fan is the upwards sucking-off of the hot gas of lower temperature in stove; and blow to combustor direction, make gas and the high-temperature gas mixing of lower temperature, pass through air channel; blow to aluminium bar in stove; form circulation, this kind " bleed type " endless form, relative to traditional " air draught type " endless form, more effectively can protect blower fan; extend the protection life-span of blower fan; and this device make high and low temperature gas and vapor permeation evenly, reduce windage, make hot blast be contorted blowout.
In order to reduce heat losses, preferred technical scheme is, described first sleeve, the second sleeve and the second air channel inwall are provided with heat insulating coat.
In order to easy to operate, preferred technical scheme is, described combustor adopts the ratio combustor that can regulate combustion power according to furnace temperature, and combustor can be made always in running order, reduces combustor and shuts down purging.
Advantage of the present invention and beneficial effect are: the present invention is by the change to thermal circulation fan position, " air draught type " endless form is made to change " bleed type " endless form, flame, furnace gas mist that " air draught type " endless form is inhaled, temperature is higher, and " bleed type " endless form, inhale be furnace gas, temperature is lower, effectively can protect blower fan, extend the service life of blower fan, thus improve the efficiency of whole hot shearing furnace; And the present invention is anti-eddy combustion room, when after blower fan blowout by anti-vortex structure reduction windage, cutting hot blast is contorted blowout, gas and vapor permeation evenly; Adoption rate combustor, the large I of combustion power adjusts according to furnace temperature, and makes combustor always in running order, reduces combustor and shuts down purging; By the improvement to structure, selecting of assembly, hot shearing furnace combustion chamber is had install easy to operate, security performance is high, and the life-span is long, and air heat uniformity is good, can the advantage such as continuous operation.
