Abstract
The invention relates to a bi-functional uniform heating device for implementing thermal convection and secondary radiation. The bi-functional uniform heating device comprises a centrifugal stirring fan and a radiant tube, wherein the heating device is mounted on a furnace top position of a heating furnace; the centrifugal stirring fan is mounted in the middle of the heating device; the radiant tube is mounted beside the centrifugal stirring fan; a secondary radiation air deflector is mounted below the centrifugal stirring fan and the radiant tube; the secondary radiation air deflector is fixed on the heating device through a heat-resistant steel pull rod and right faces the furnace top position of the heating furnace; the heat of the radiant tube is absorbed through the secondary radiation air deflector; heat accumulation and formation of a high-temperature zone are performed between the radiant tube and the secondary radiation air deflector; heat is uniformly radiated downwards through the surface of the secondary radiation air deflector. With adoption of this technology, the bi-functional uniform heating device achieves the uniform radiation and thermal convection, improves the uniformity of the furnace, and avoids unqualified local quality due to uneven heating of workpieces, while activating the furnace atmosphere and protecting the surfaces of the workpieces.
Description
Technical field
The invention belongs to the heating device technology area of heat-treatment production line, particularly relate to a kind of difunctional device for homogenous heating realizing thermal convection current and secondary radiation.
Background technology
Existing mode of heating, adopt the heating of tailored radiation pipe, just larger temperature difference is there is near radiant tube region with away from radiant tube region, workpiece is caused to be heated uneven, there is underheat phenomenon or overheated in workpiece regional area, product local occurs that metallographic lacks the defective metallographic such as level (underheat) or lamellar pearlite (overheated).Existing settling mode mostly is:
1, adopt larger blower fan to stir, destroy the layering of furnace protection atmosphere, cause new quality problems, add equipment cost, improve blower fan and make power consumption.
2, adopt small-power branched radiant tube radiation to be shared equally, increase furnace shell perforate, cause potential gas leakage, and device fabrication, buying, use cost all increase substantially.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide one that high-power radiant tube can be coordinated to use, homogeneous heating, the difunctional device for homogenous heating of what cost was controlled realize thermal convection current and secondary radiation.
The object of the invention is to have come by following technical solution.This difunctional device for homogenous heating realizing thermal convection current and secondary radiation, comprise centrifugal mixer blower fan and radiant tube, described heater is arranged on the furnace roof position of heating furnace, described centrifugal mixer assembling is in the centre of heater, radiant tube is arranged on centrifugal mixer blower fan side, secondary radiation wind deflector is arranged on the below of centrifugal mixer blower fan and radiant tube, and this secondary radiation wind deflector is fixed on heater by heat resisting steel pull bar, and is right against the furnace roof position of heating furnace; By secondary radiation wind deflector radiation-absorbing pipe temperature, accumulation of heat between radiant tube and secondary radiation wind deflector also forms high temperate zone, by secondary radiation wind deflector surface by even heat downward radiation.
As preferably, the centre of described secondary radiation wind deflector offers ventilation hole, is connected with centrifugal mixer blower fan by this ventilation hole; The entirety of secondary radiation wind deflector is smooth shape, and the structure at its edge is obtuse angle shape.
Beneficial effect of the present invention is: adopt this technology, achieves the homogenising of radiation and thermal convection current simultaneously, improves burner hearth uniformity, avoids workpiece to occur that local quality is defective because of inequality of being heated, serves activation oven cavity atmosphere simultaneously, the effect of protection surface of the work.

Detailed description of the invention
Below in conjunction with
accompanying drawingdetailed introduction is done to the present invention: as
accompanying drawing 1, shown in 2, the present invention includes centrifugal mixer blower fan 1 and radiant tube 3, described heater is arranged on the furnace roof position of heating furnace 6, described centrifugal mixer blower fan 1 is arranged on the centre of heater, radiant tube 3 is arranged on centrifugal mixer blower fan 1 side, secondary radiation wind deflector 4 is arranged on the below of centrifugal mixer blower fan 1 and radiant tube 3, and this secondary radiation wind deflector 4 is fixed on heater by heat resisting steel pull bar 2, and is right against the furnace roof position of heating furnace 6; By secondary radiation wind deflector 4 radiation-absorbing pipe 3 temperature, accumulation of heat between radiant tube 3 and secondary radiation wind deflector 4 also forms high temperate zone, by secondary radiation wind deflector 4 surface by even heat downward radiation.
The centre of described secondary radiation wind deflector 4 offers ventilation hole 41 and is convenient to centrifugal mixer blower fan 1 air draught, is connected with centrifugal mixer blower fan 1 by this ventilation hole 41; The entirety of secondary radiation wind deflector 4 is that smooth shape is convenient to homogeneous radiation and wind-guiding, and the structure at its edge is that obtuse angle shape can guide hot blast to spread; 1, secondary radiation wind deflector 4 radiation-absorbing pipe 3 temperature is utilized, then by secondary radiation wind deflector 4 surface by even heat downward radiation; 2, utilize secondary radiation wind deflector 4, the effect of centrifugal mixer blower fan 1 of central authorities is strengthened, and air draught power is stronger, and the hot air flow being heated rear formation by radiant tube 3 is to evenly controlled; 3, utilize secondary radiation wind deflector 4 accumulation of heat between radiant tube 3 and secondary radiation wind deflector 4, form high temperate zone, when the enriched gas in furnace protection atmosphere is recycled to this position by blower fan, easier cracking produces
active carbon, contribute to oven cavity atmosphere, reduce heat treatment of workpieces skin decarburization.
The present invention during fabrication, first according to design outline assembled welding secondary radiation wind deflector 4 and lining muscle thereof, afterwards radiant tube 3 and centrifugal mixer blower fan 1 are installed on heating furnace 6, then equipped secondary radiation wind deflector 4, and are fixed in body of heater top with heat resisting steel pull bar 2; Workpiece 5 passes through in secondary radiation wind deflector 4 bottom, raying and thermal convection current homogeneous heating.
The present invention is not limited to above-mentioned embodiment, no matter do any change, every employing structural design provided by the present invention on its shape or material are formed, is all one distortion of the present invention, all should thinks within scope.
