An environment-friendly and energy-saving dryer

Abstract

The invention discloses an environment-friendly and energy-saving dryer, which comprises a drying cylinder, a heating layer is installed in the drying cylinder, a thermal insulation cavity is arranged between the heating layer and the drying cylinder, and a heating layer is installed in the drying cylinder. There is a feeding pipe, the feeding pipe passes through the upper end of the heating layer, a spiral surface is arranged in the feeding pipe, a plurality of inclined plates are installed in the heating layer, a rotating mechanism is arranged at the bottom of the heating layer, The rotating mechanism includes a turntable on which a plurality of oblique arc-shaped plates are fixedly connected. A driving mechanism is installed on the bottom of the drying cylinder, and the driving mechanism includes a driving sprocket and a driven sprocket. In the present invention, a plurality of oblique arc-shaped plates are installed on the turntable. When the material rotates under the action of centrifugal force, the material will be blocked by the inclined-arc-shaped plates after being separated from the inclined-arc-shaped plates. The materials will be blocked layer by layer and cannot move in a straight line Instead of peripheral movement, it moves spirally to the periphery, which greatly increases the time and path for materials to dry inside the heating layer.

Description

technical field [0001] The invention relates to the technical field of dryers, in particular to an environment-friendly and energy-saving dryer. Background technique [0002] Grains such as rice and wheat are the necessities of daily consumption in our country, and the consumption is very large. The freshly harvested grains have a high water content and need to be dried and watered before they can be stored for a long time. [0003] After retrieval, the Chinese patent number: CN201410038834.1 discloses an environmentally friendly and energy-saving dryer, which has a simple and reasonable structural design, is convenient to manufacture, and reduces costs; it is easy to operate and saves manpower; it has high drying efficiency and good effect, and avoids grain waste . [0004] From the comparative document, multiple rolling drying tubes are used for drying, and drying is carried out by heating while rolling and outputting. Simply adding a straight line path for heating and dr...

Problems solved by technology

[0004] From the comparative document, multiple rolling drying tubes are used for drying, and drying is carried out by heating while rolling and outputting. Simply adding a straight line path for heating and drying, horizontally placed rolling drying tubes will greatly increase the volume of the equipment, and In the drying process, the evaporated water vapor is not treated, the material needs to go through a long horizontal distance, and a single method of heating and evaporating cannot guarantee good drying efficiency
