In order to prevent high-moisture materials from being clamped between the two rakes and rotate with the rakes, or to speed up the moving speed of the material, the distance between the rakes or the length of the scraper is intentionally increased, resulting in the material ring coverage area being even smaller than the exposed area , the effective heating area of the heating plate is less than 50%, which seriously affects the normal performance of the dryer

Abstract
The invention discloses a heat pipe heating type disk dryer. The heat pipe heating type disk dryer includes a drying bin, an air exhaust device, a feeding device, a variable speed motor, a support frame, a small heating plate, a large heating plate, a lower rake rod, a transmission shaft, an upper rake rod, and a support. The material drying process of the heat pipe heating type disc dryer is a vacuum drying process or a convection drying process. A heat-conducting working medium carries thermal energy and performs heat conduction and heat exchange to the material through top plates of the large heating plate and the small heating plate. The material on the top plate of the heating plate of the large heating plate conveniently moves from the top plate which is higher on the outside and lower on the inside in an internal rotation mode from the outside to the inside, and the material on the top plate of the heating plate of the small heating plate conveniently moves from the top plate which is higher in the inside and lower on the outside in an external rotation mode from the inside to the outside; the material is covered on the top plates of the large heating plate and the small heating plate under the guidance and diversion paving of a rake blade device, the upper and lower heating intensities of the material are improved, drying uniformity of the material water content is improved, and the effective heating area of the top plates of the large heating plate and the small heating plate are greater than 90%.
Description
technical field [0001] The invention relates to a disc dryer, in particular to a heat pipe heating disc dryer. Background technique [0002] The heating discs installed in the disc dryers currently on the market are multi-layered, and the dried materials are dried on the heating discs through alternate internal rotation or external rotation. The heating plate of the disc dryer uses heat conduction to provide heat to the material. Due to the large internal space of the heating plate, the heat transfer medium around the heating plate flows slowly or does not flow, and the heat conduction medium on the top plate around the heating plate The heat is less, so that the materials on the top plate around the inner periphery of the heating plate cannot receive sufficient heat to dry. After the heat transfer medium flows in the heating plate for a long time, it is easy to generate scale and oil. The internal structure of the heating plate is complicated and it is not easy to clean th...
