The invention relates to electric heating devices and can be used for heat treatment of paints and varnishes on products “transported on a conveyor.

An object of the invention is to expand the technological capabilities of an infrared radiation generator.

In FIG. 1 illustrates an infrared radiation generator, an axonometer; in FIG. 2

- the same, front view; in FIG. 3 a, b. at

- various positions of the reflector sections; in FIG. 4a, b, into irradiation zones of different heights and densities with different rotation of the reflector sections.

The infrared radiation generator comprises an emitter 1 and a parabolic reflector 2 mounted movably relative to the longitudinal axis of the emitter 1. The reflector 2 is made along the length of a set of, for example, three sections 3-5, mounted movably relative to each other.

The end sections 3 and 5 have outer end walls b and 7 and inner half-ring flanges 8 and 9 for connection with half-ring flanges 10 and 11 of the middle section. Flanges 8-11 have holes in which bolt connections are located 12. The emitter 1, for example, in the form of a quartz halogen lamp is attached to the walls 6 and 7 of sections 3 and 5 using a collet clamp 13. Sections 3-5 can be made of different lengths and installed under different

angle depending on the height of the workpiece 14.

The infrared radiation generator operates as follows.

The generator is assembled by bolting 12 sections 3-5 at a different angle relative to the longitudinal axis of the emitter 1. Turn on the latter and irradiate the treated surface of the articles 14 moved relative to the emitter 1 (see Fig. 4).

Using the invention, it is possible to change the vertical size of the directional irradiation zone from one emitter, and also to control the heat flux density in different parts of the treated surface by installing one (see Fig.), Two (see Fig. 0) or more ( for example, three, see Fig.) sections of the reflector. As a result, products of different thicknesses and configurations can be processed.
