Recovery type solar drying device

Abstract

The invention relates to a recovery type solar drying device, comprising: 1. a hot air flow heat-collecting and heat-storing circulating system implemented by components such as an all-glass vacuum heat-collecting tube, a heat tube (2), a heat-dissipating piece (3), a metal net layer (4), a pebble heat-storing device (5), a heat exchange device (9), a variable-frequency speed-regulating fan (8) and the like; 2. a material drying system implemented by components such as a material drying insulating box (10), a netty material drying box (21), a fan (24), a material (25) to be dried and the like; 3. a dried material water recovery system implemented by components such as a dried material steam discharge device (11), a condensing device (12), a dried material water recovery pipeline (14) and the like; and 4. components including a valve, an electric auxiliary heating device, a sensor and the like. The recovery type solar drying device has wide application range, can dry different types of materials and form series of products of the solar drying device.

Description

technical field [0001] The invention relates to a recovery type solar drying device which can not only collect heat and store heat, but also recover moisture in drying materials. Background technique [0002] Existing solar drying device, utility model application number: 200520086384.X, a kind of solar drying device has low utilization rate of solar energy and drying equipment, and it is difficult to form large-scale and serialized industries in the material drying industry, especially It is the disadvantage that the water with deep processing value cannot be recovered during the drying process of materials. Contents of the invention [0003] The purpose of the present invention is to provide a solar drying device that has the function of heat collection and heat storage, and can recycle the moisture in the drying materials, so as to overcome the shortcomings in the existing solar drying technology; the invention does not consume disposable energy , does not pollute the ...
