Solar drying device

Abstract

The invention discloses a solar drying device. The device comprises a storage rack and a lens, the storage rack is used for placing an object to be dried, the lens is arranged above the storage rack, the lens comprises a plurality of ridge sets, and light rays emitted into the lens are gathered at the two sides of the storage rack through the ridge sets so as to heat and dry the object on the storage rack. In the using process, the object to be dried is placed on the storage rack, solar rays are emitted into the lens, the incident solar rays are refracted and gathered to the two sides of the storage rack through the ridge sets on the lens, and therefore the object on the storage rack is subjected to low-power condensation double-face heating, and the vertically-designed storage rack can achieve uniform irradiation of the two faces of a washed object; and moreover, the vertical placement space utilization rate is high, water drops easily drop, rapid drying can be achieved through photo-thermal conversion, and the solar drying device is suitable for the technical field of solar energy.

Description

technical field [0001] The invention is used in the technical field of solar energy, and in particular relates to a solar drying device. Background technique [0002] For the rapid drying technology, most of them use the method of heating air, generally using electric energy for direct heating. And some drying methods combined with solar energy also use heat-absorbing plates to absorb light and heat, heat the air through the heat-absorbing plates and then use hot air to dry, or use photovoltaic panels to convert solar energy into electrical energy first, and then Electric energy is converted into heat energy, and then the air is heated, and the moisture on the laundry is taken away through the hot air. This method uses hot air as an intermediate medium and performs multiple energy conversions. The efficiency is low, and the system has many components and structure. It is complicated. If sunlight is used to directly heat the laundry, firstly, the sunlight energy density is l...

And some drying methods combined with solar energy also use heat-absorbing plates to absorb light and heat, heat the air through the heat-absorbing plates and then use hot air to dry, or use photovoltaic panels to convert solar energy into electrical energy first, and then Electric energy is converted into heat energy, and then the air is heated, and the moisture on the laundry is taken away through the hot air. This method uses hot air as an intermediate medium and performs multiple energy conversions. The efficiency is low, and the system has many components and structure. Complicated, if sunlight is used to directly heat the laundry, firstly, the sunlight energy density is low, and the drying rate is not enough; secondly, the sun can only illuminate one side of the laundry at the same time, resulting in a low drying rate
