FIELD: infrared treatment of preformed plastic pills.
SUBSTANCE: the invention presents an upgraded infrared heater for conditioning of previously formed plastic pills. The infrared heater for heating up a set of the previously preformed plastic pills provides for: a box through which the indicated preformed plastic pills are moving; a stream of outside air, which flows along the indicated box from the inlet device to the exhaust window under action of the positive blower; a set of the infrared lamps irradiating preformed plastic pills in the indicated box, in which below the course along the air stream running way relatively to the indicated infrared lamps there is a deflecting surface supplied with windows, through which a stream of the outside air is predominary passing. Axes of preformed plastic pills are oriented so, that they are practically perpendicular to the direction of the indicated outside air stream. The infrared lamps are located practically along the course of the outside air stream flow and below in respect to the preformed plastic pills and are spaced one from another by corresponding intervals, through which passes the indicated outside air stream is passing. At that the indicated outside air stream first passes through the indicated intervals separating the indicated performed plastic pills, and then - through the indicated spaces made between indicated infrared lamps. The deflecting surface, which is supplied with windows, so that the stream of the outside air can partially pass through them, is located along the course of the outside air stream pass and above in respect the indicated preformed plastic pills. The technical result consists in development of the infrared heater simple in design and realization, safe and reliable in operation with a stable air stream and adequate reflective efficacy.
EFFECT: the invention presents the infrared heater simple in design and realization, safe and reliable in operation with a stable air stream and adequate reflective efficacy.
