Efficient dryer

Abstract

The invention discloses an efficient dryer, and belongs to the mechanical technical field. The efficient dryer comprises a combustion chamber; a combustor is arranged on the left side wall of the combustion chamber; a heat insulating layer is arranged on each of the top and the bottom of an inner cavity of the combustion chamber; and a drying box is arranged at the right end of the combustion chamber. The efficient dryer is reasonable in setting, is safe and practical; the combustion chamber and the drying box are isolated, so that high-temperature flames are in a combustion cavity all the time, and only hot air enters the drying box. Poisonous high-risk pollutants such as dioxin which can be possibly generated as a result of direct contact of high-temperature flames and materials are avoided, and the temperature in the drying box is more uniform; a dust collecting device can be adopted to filter harmful gas in the drying box, so that the exhausted gas is guaranteed to reach standards, and environmental pollution is avoided; and plough-shaped stirring blades have turnover effect while materials are clustered, have cutting effect during a material sticking stage, and further have up-down stirring effect while having the turnover effect and the cutting effect.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a high-efficiency dryer. Background technique [0002] Dryers can be divided into industrial and civilian. Industrial dryers are also called drying equipment or dryers. Civilian dryers are one of washing machines. They are generally used to remove clothing and other textiles after washing and dehydration. of moisture. The dryer has several modes such as belt drying, drum drying, box drying, and tower drying; the heat source includes coal, electricity, gas, etc.; the drying process of materials has hot air flow type and radiation type, etc. , hot air drum drying is that the hot air flow moves forward from the tail, fully contacts with the material, and makes full use of the heat transfer through heat conduction, convection, and radiation; the heat energy is directly transferred to the material, so that the moisture of the material is continuously evaporated in the cylinder, and...
