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 the hot shearing furnace, long excellent hot shearing furnace is the ineffective activity for the old-fashioned stub heating furnace of aluminium alloy industry waste material, scheduling of production, and designs novel aluminium bar heating, shearing stove.The combustion chamber of traditional hot shearing furnace directly is connected with the air outlet of body of heater, thermal circulation fan is arranged between the air inlet of combustor and body of heater, because thermal circulation fan directly sucks high-temperature gas in the combustion chamber, then be blown in the hot shears body of heater, this kind mode will cause thermal circulation fan directly to suck flame, furnace gas mist, temperature is very high, be easy to cause the damage of extension set, reduce service life, and this kind connected mode, easily cause gas temperature to mix inhomogeneous, thereby easily cause non-uniform temperature in the hot shearing furnace.
Summary of the invention
The object of the invention is to overcome the defective that exists in the prior art, provide fitting operation convenient, security performance is high, and the life-span is long, air heat good uniformity, the anti-turbulence chamber of continuous type bleed type for hot shearing furnace.
For achieving the above object, technical scheme of the present invention has provided the anti-turbulence chamber of a kind of bleed type for hot shearing furnace, the thermal circulation fan that comprises combustor, is connected by the 3rd air channel with described combustor, air outlet and the air inlet of hot shearing furnace body of heater, described thermal circulation fan is connected by the first air channel with air outlet, and described combustor is connected by the second air channel with air inlet.Thermal circulation fan is the sucking-off that makes progress of the hot gas of lower temperature in the stove; and blow to the combustor direction; gas and the high-temperature gas of lower temperature are mixed; pass through the air channel; blow to aluminium bar in the stove, form circulation, this kind " bleed type " endless form is with respect to traditional " air draught type " endless form; more can effectively protect blower fan, prolong the protection life-span of blower fan.
More even for the gas mixing that makes high and low temperature, preferred technical scheme is that described combustor nozzle is fixedly installed in the first sleeve.
In order to reduce windage, make hot blast be the rotation shape and blow out, preferred technical scheme is to be provided with helical groove on described the first sleeve lining.
For cold wind and hot blast are mixed, reduce windage, preferably technical scheme is, and described the first sleeve outer setting has the second sleeve, and described the second sleeve makes described second channel be connected with described the 3rd air channel.
Run off in order to reduce heat, preferred technical scheme is that described the first sleeve, the second sleeve and the second air channel inwall are provided with heat insulating coat.
For easy to operate, preferred technical scheme is that described combustor adopts the ratio combustor that can regulate according to furnace temperature combustion power, can make combustor 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 the thermal circulation fan position, make " air draught type " endless form 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 is inhaled to such an extent that be furnace gas, temperature is lower, can effectively protect blower fan, prolong the service life of blower fan, thereby improve the efficient of whole hot shearing furnace; And the present invention is anti-eddy combustion chamber, reduces windage by anti-vortex structure after blower fan blows out, and cuts hot blast and is the rotation shape and blows out, and it is more even that gas mixes; The adoption rate combustor, the large I of combustion power is adjusted 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 makes the hot shearing furnace combustion chamber have fitting operation conveniently, and security performance is high, and the life-span is long, air heat good uniformity, but the advantages such as continuous operation.
