Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Figure 1-4, be furnace pressure automaton of the present utility model, comprise heating furnace 1, flue 2 and high pressure gas proscenia 3.Heating furnace 1 is provided with entrance 101 and outlet 102.Flue 2 is positioned at entrance 101 place of heating furnace 1, and flue 2 is provided with pressure electric control valve 1, and the pressure at entrance 101 place monitored by pressure electric control valve 1, and can by controlling the aperture of flue 2 to regulate the pressure at entrance 101 place.High pressure gas proscenia 3 is positioned at outlet 102 place of heating furnace 1, and high pressure gas proscenia 3 is provided with pressure tester 1, and pressure tester 1 monitors the pressure at outlet 102 place, and can by controlling the aperture of high pressure gas proscenia 3 to regulate the pressure at outlet 102 place.In the present embodiment, high pressure gas proscenia 3 is air curtain burner.
Be provided with smoke backflow delivery pipe 6 between flue 2 and high pressure gas proscenia 3, smoke backflow delivery pipe 6 is provided with pressure electric control valve 27, and heating furnace 1 is provided with the pressure tester 28 be electrically connected with pressure electric control valve 27.One end of the close high pressure gas proscenia 3 of smoke backflow delivery pipe 6 is socketed with cooling collar 9, and cooling medium is wind.
Be distributed with the thermocouple 11 of multiple burner 10 and measure local temperature between flue 2 and high pressure gas proscenia 3, thermocouple 11 is electrically connected with burner 10.In staggered relative, distribution is also inclined upwardly burner 10 in the horizontal direction.
The body of heater of heating furnace 1 is distributed with multiple observation window 12, in order to observe steel wire heating situation in heating furnace 1.
Operationally, electric control valve 1 controls the aperture of flue 2 to furnace pressure automaton of the present utility model, ensures that the furnace pressure at entrance 101 place of heating furnace 1 is stablized.When carrying out the blow-on doors 103 such as scarfing cinder to steel wire and operating, furnace pressure reduces, and electric control valve 1 monitors this signal, controls flue 2 and reduces aperture, make furnace pressure increase to normal value; When furnace pressure increases, electric control valve 1 controls flue 2 and increases aperture, discharges excessive pressure.Heating furnace 1 exports the high pressure gas proscenia 3 inject high pressure air curtain at 102 places, and sealing outlet 102, to prevent in stove high thermal pressure toward stove external diffusion.When pressure tester 1 monitor outlet 102 place pressure depart from furnace pressure normal value time, to high pressure gas proscenia 3 one signal, make the corresponding increase of high pressure gas proscenia 3 or reduce aperture, with the furnace pressure at this stabilization of export 102 place.When the furnace pressure of heating furnace 1 inside is too high, pressure tester 28 monitors this signal, sends electric control valve 27 to, electric control valve 27 controls smoke backflow delivery pipe 6 and increases aperture, the flue gas be discharged, through the cold front heavy rain of cooling collar 9, is back in heating furnace 1, recycles.Meanwhile, thermocouple 11 monitors the too high signal of temperature, sends burner 10 to, makes burner 10 reduce burning velocity; When the furnace pressure of heating furnace 1 inside or furnace temperature too low time, electric control valve 27 and thermocouple 11 Reverse Turning Control.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain that the utility model requires.
