A high-efficiency solar rapid drying equipment

Abstract

An efficient and fast solar drying device comprises a drying cylinder, a support, a reflector, a driving motor, a driving belt wheel, a driven belt wheel and a belt. The drying cylinder is installed on the top of the support through bearings, and a material inlet and a material outlet of the drying cylinder are located on the same side of a cylinder body. The driving motor is arranged at the bottom of the support, the driving belt wheel is installed on a motor shaft of the driving motor, the driven belt wheel is installed on a spindle of the drying cylinder, and the driving belt wheel and the driven belt wheel are connected through a belt. The reflector is located below the drying cylinder in an oblique mode, and the outer cylinder wall of the drying cylinder corresponds to the reflecting surface of the reflector. A solar cell panel is installed on the top edge of the reflector, and power is supplied to the driving motor through the solar cell panel. The reflector and the support are connected in a hinged mode, a supporting leg is hinged to the back face of the reflector, and the reflecting angle of the reflector is adjusted through the supporting leg. A spiral shoveling plate is installed on the inner cylinder wall of the drying cylinder. The outer cylinder wall of the drying cylinder is wrapped by a heat absorbing layer. A single curved parabolic face is adopted for the reflecting surface of the reflector.

Description

technical field [0001] The invention belongs to the technical field of solar drying, in particular to a high-efficiency solar rapid drying equipment. Background technique [0002] With the increasingly serious problems of energy shortage and environmental pollution, energy conservation and emission reduction have attracted widespread attention. In industrial and agricultural production, drying operations involve a wide range of areas of the national economy, and are also one of the largest energy-consuming households in my country. About 12% of the total energy consumption of the national economy. [0003] With the continuous enhancement of people's awareness of energy saving and emission reduction, it has become an inevitable trend to introduce solar energy into the field of material drying. Through the use of solar energy resources, the consumption of conventional energy can be greatly reduced. [0004] However, most of the current solar drying equipment uses solar energy ...

AI Technical Summary

Problems solved by technology

[0005] When the above drying method is adopted, due to the low thermal conductivity of the air and the short contact time with the heat collector, the drying efficiency is not high and the drying time of the material is prolonged.

At the same time, the materials in most of the existing solar drying equipment are in a static state, which leads to uneven heating of the materials and unsatisfactory drying effect of the materials
