Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is made a detailed explanation.
A kind of heating furnace as shown in Figure 1 to 4, comprise body of heater 20 and heat-exchanger rig 14, described heat-exchanger rig 14 comprises air blast 1 and heat exchanger tube 2, described heat exchanger tube 2 comprises interior pipe 3 and outer tube 4, described interior pipe 3 is hollow steel pipe with outer tube 4, interior pipe 3 is rolled by 1Cr13 corrosion resistant plate and is welded, and outer tube 4 is rolled by Q235 steel plate and is welded.The diameter of interior pipe 3 is between interior pipe 3 and outer tube 4, because diameter is different thus formed every dead level (figure does not mark).Be provided with into mouth 5 in the bottom of interior pipe 3, the top of interior pipe 3 is provided with outlet flue 6; The upper end of outer tube 4 is provided with air inlet 7, and the lower end of outer tube 4 is provided with air outlet 8, and the air inlet 7 of outer tube 4 upper end is connected with air blast 1, and the air outlet 8 of outer tube 4 lower end passes into the inside of heating furnace by pipeline; Between the outer wall and the inwall of outer tube 4 of interior pipe 3, be evenly provided with multiple by fin 9, described fin 9 be made up of Q235 steel plate.Fin 9 be arranged between interior pipe 3 and outer tube 4 in dead level, and and between interior pipe 3 and outer tube 4, form multiple gas channel 10.Described body of heater 20 comprises furnace shell 21, bell 22, burner hearth 24 and crucible 23, and described crucible 23 is arranged on the center of burner hearth 24, and the bottom of body of heater 20 is also provided with pedestal 25, and crucible 23 is shelved on pedestal 25; Described bell 22 is provided with venthole 26 and air admission hole 27, outlet flue 5 is connected with venthole 26 by pipeline, and air outlet 8 is connected with air admission hole 27 by pipeline.The other end of the pipeline be connected with air outlet 8 is connected with burner 13 through air admission hole 27, and burner 13 is also connected with gas inlet pipeline (figure does not identify), thus makes combustion gas and air mix at burner place and light, thus realizes heating process.
Described air blast 1 realizes being flexible coupling by canvas 12 with air inlet 7.Canvas 12 is adopted to be flexible coupling, with low cost, implement simple, effectively can absorb the vibrations produced when air blast 1 works, effectively prevent because vibrations cause pipeline to leak in junction.The air inducing circle 11 of inner wall smooth is provided with at air inlet 7 place.Arrange air inducing circle 11, canvas 12 can better be coordinated with air inlet 7, simultaneously due to the inner wall smooth of air inducing circle 11, when making inlet air, air quantity is more concentrated, also can play the effect reducing noise simultaneously.
