Summary of the invention
For above deficiency, the object of the present invention is to provide a kind of fast cooling device of heat treatment furnace, be, by pipeline, the hot blast of drawing burner hearth is divided into two-way, a road is directly discharged to outside stove, and a road and gas blower return in stove after taking out the freezing air mixing come; By regulating the angle of the electric butterfly valve on each pipeline to control each pipeline flow, indirectly controlling in-furnace temperature, making furnace temperature possess controllability.
Technical scheme of the present invention is achieved in the following ways
:a kind of fast cooling device of heat treatment furnace, by induced exhaust, backwind tube, exhaust duct, mix cold-air duct, electric butterfly valve, high temperature draught fan, gas blower and thermopair and heat treatment furnace composition, described heat treatment furnace upper end is provided with backwind tube, lower end is provided with induced exhaust, induced exhaust and backwind tube are connected to the outside of heat treatment furnace body by high temperature draught fan, backwind tube is provided with exhaust duct and mixes cold-air duct near induced exhaust junction, exhaust duct is upwards extended, communicate with air, it is characterized in that: described cold-air duct of mixing is extended downwards, be connected with gas blower, by cold wind through mixing cold-air duct, backwind tube enters heat treatment furnace burner hearth top, regulate temperature in burner hearth.
Described induced exhaust, backwind tube, exhaust duct, mix in cold-air duct and be provided with electric butterfly valve.
Described backwind tube is also being provided with thermopair near heat treatment furnace exit.
The present invention, by a hot blast shunting part of discharging heat treatment furnace being mixed in heat treatment furnace with the cold wind introduced, and controlling the air flow quantity of each pipeline by controlling ducted each electric butterfly valve, effectively controlling the furnace temperature in heat treatment furnace.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
In figure: 1 induced exhaust, 2 backwind tubes, 3 exhaust ducts, 4 mix cold-air duct, 5 electric butterfly valves, 6 high temperature draught fan, 7 gas blowers, 8 thermopairs, 9 heat treatment furnaces.
Embodiment
Known by Fig. 1, a kind of fast cooling device of heat treatment furnace, by induced exhaust 1, backwind tube 2, exhaust duct 3, mix cold-air duct 4, electric butterfly valve 5, high temperature draught fan 6, gas blower 7 and thermopair 8 and form, the left end of described induced exhaust 1 is arranged on the bottom of heat treatment furnace 9 burner hearth, and right-hand member is connected on the blast inlet of high temperature draught fan 6; The upper end of described backwind tube 2 is arranged on the top of heat treatment furnace 9 burner hearth, and lower end is connected on high temperature draught fan 6 air outlet; The upper end of described exhaust duct 3 is stretched out outside workshop, is directly exposed in air, and lower end is connected to the bottom of backwind tube 2; The upper end of mixing cold-air duct 4 is connected to the middle and lower part of backwind tube 2, and lower end is connected on gas blower 7; Described induced exhaust 1, backwind tube 2, exhaust duct 3, mix in cold-air duct 4 and be all provided with electric butterfly valve 5, for controlling the flow of each pipeline; Between electric butterfly valve 5 and heat treatment furnace 9, being also provided with thermopair 8 in described backwind tube 2, entering the temperature before heat treatment furnace 9 for measuring mixing air in backwind tube 2.The hot blast of heat treatment furnace 9 is drawn from induced exhaust 1, and a part is discharged through exhaust duct 3, another part by gas blower 7 be blown into cold wind through mixing cold-air duct 4, backwind tube 2 enters heat treatment furnace 9 upper furnace, regulates temperature in burner hearth.
In Fig. 1, arrow represents the direction of wind flow, during work, hot blast is drawn from heat treatment furnace 9 burner hearth bottom by induced exhaust 1 by high temperature draught fan 6, the hot blast of drawing is divided into two-way in backwind tube 2, one road is directly discharged from exhaust duct 3, and a road is back to heat treatment furnace 9 upper furnace with mixing after cold wind that cold-air duct 4 introduces mixes; Exhaust duct 3, electric butterfly valve 5 angle of mixing in cold-air duct 4, for measuring the temperature of mixing air, when needing the temperature improving the mixing air entered in stove, can be turned down by the thermopair 8 in backwind tube 2; When needing the temperature reducing the mixing air entered in stove, exhaust duct 3, electric butterfly valve 5 angle of mixing in cold-air duct 4 can be tuned up; When needs reduce in-furnace temperature fast, induced exhaust 1, backwind tube 2, exhaust duct 3, electric butterfly valve 5 angle of mixing in cold-air duct 4 all can be tuned up; When needs slowly reduce furnace temperature, induced exhaust 1, backwind tube 2, exhaust duct 3, electric butterfly valve 5 angle of mixing in cold-air duct 4 all can be turned down.
The present invention, by by a hot blast shunting part of discharging heat treatment furnace 9 with mix cold wind that cold-air duct 4 introduces and mix and control the air themperature that backwind tube 2 introduces heat treatment furnace 9, the air flow quantity of each pipeline is controlled by the electric butterfly valve 5 controlling each pipeline, indirectly control the furnace temperature of heat treatment furnace 9, the present invention is simple and practical, can adapt to complicated thermal treatment process.
