Abstract
The invention discloses a multi-reflecting-surface parabola type infrared radiant energy total reflection cover which comprises a gas combusting and heating radiant tube. Heat is converted by the radiant tube to generate radial infrared rays. The infrared rays are reflected to a heating area through reflecting surfaces on reflecting cover bodies, and the reflecting cover bodies are two parabola type reflecting cover bodies. The center line of the radiant tube is arranged on the longitudinal perpendicular line of the coincident point of the two parabola type reflecting cover bodies, and an outer contour line of the radiant tube is tangent to the extending contour lines of the two parabola type reflecting cover bodies. The lowest end of the outer contour line of the radiant tube and the lower bottom faces of the parabola type reflecting cover bodies are located on the same straight line. The radial infrared rays radiate on the reflecting surfaces and are reflected to the position below the radiant tube through the reflecting surfaces. The multi-reflecting-surface parabola type infrared radiant energy total reflection cover has the beneficial effects that the characteristic of a curved surface of a standard parabola is utilized, the six reflecting planes are adopted, and therefore the 360-degree infrared rays generated by the radiant tube all can pass through the reflecting surfaces, and all the infrared rays are reflected out through primary reflection and secondary reflection.

Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The present invention is illustrated below in conjunction with accompanying drawing, as it is shown in figure 1, the parabolic type infrared radiation of multiple reflection face can be totally reflected cover, including fuel gas buring heating radiation pipe 12, heat is converted by radial canal 12 and produces radial infrared ray, the infrared ray 1,2,3,4,5,6 in figure；Infrared ray is reflected the reflective surface on cover 10 to the thermal treatment zone, described reflector 10 is two parabolic type reflectors, radial canal centrage p is arranged on two parabolic reflective cover coincidence point longitudinal direction vertical lines (above-below direction of longitudinal direction and Fig. 1), and the prolongation contour line 11 of radial canal profile 13 and two parabolic reflective covers is tangent；Radial canal profile bottom m and parabolic reflective cover bottom surface n is on the same line；Radial infrared radiation is to reflecting surface, and the face of being reflected reflexes to below radial canal.
Described reflecting surface is that multiple plane reflecting surface connects to form, such as reflecting surface A, B, C, D, E, F of Fig. 1.The plurality of reflecting surface connects into entirety by the shape arc of reference parabola 18.
By setting the opening shape of parabolic irdome.20cm place, outlet lower section under reflector, reflected ray should ensure that plumbness, otherwise easily causes the radiation energy arriving ground not enough, although observes from surface and thinks that radiation witdth increases, but can not effectively do work (adding hot object)；
Implementing such as Fig. 1, radial canal diameter is 102mm, and step is as follows:
1. first setting up reflector parabola model on Autocad, design parameter is:
P=71mm；Focus: F (0,35.5)；
According to parabolic equation x2=-2Py, obtains the parabola that A/F is 280mm, is highly 140mm；
2. mirror image parabola, makes the two paraboloidal cross facets focus by the other side, obtained hyperbolic face shield as shown in Figure 1, on this basis, it is determined that the relative position of infrared radiation pipe, namely, radiation pipeline surface camber line and two parabola both sides are tangent, obtain the pipeline concrete coordinate in curved surface；
Checking:
Doing simulation radiation on radiation pipeline, from central point towards periphery radially, radiation quantity is with 64 for analog basis, and radiation etc. divides 360 ° for radiation；
Further, every radiation intersects with parabola, is perpendicular to paraboloidal vertical line (i.e. normal 14) in joining, according to light line reflection ultimate principle, makes reflected ray；
And then draw the line reflection face at areflexia dead angle；Such as: No. 1 radiation, for reflecting surface F, it is produce the most probable region of dead angle, if can accomplish that reflection is unobstructed in this angle of radiation, then other radiation on this F reflecting surface realize reflection surely with regard to one；By that analogy, MIN plane reflection face is made；
Being measured by three points for measuring temperature 14,16,17, reflector back temperature is not higher than 28 DEG C；
In figure, 8 is primary event line, and 9 is secondary radiation.
