Title: CHAIN SCRAPER-BASED DRYING APPARATUS
Abstract:
A chain scraper-based drying apparatus, comprising a box (10), at least two heat exchange plates (40) provided in the box (10), and at least one set of chain scraper devices (70) provided in the box (10); the box (10) is provided with a feed port (2), a discharge port (8), and a stream outlet (3); the heat exchange plates (40) are square metal hollow structures; each heat exchange plate (40) is provided with a heat exchange plate inlet (41) and a heat exchange plate outlet (42) through which a heating medium is fed and discharged; a material channel (5) exists between two adjacent heat exchange plates (40); the chain scraper devices (70) are provided in the material channel (5) above the heat exchange plate (40); each set of chain scraper devices (70) comprises two sprocket sets (71), two transfer chains (72), and a scraper (73) fixed between the two transfer chains (72). The drying device has a large heat exchange area, can use a variety of types of heating media, achieves high productivity of a single device, and can accurately obtain a dry solid material having a moisture content within a desired range; moreover, drying apparatuses having different drying capabilities can be formed by adjusting the number of the heat exchange plates (40).
