Barn solar direct heating device and solar auxiliary direct heating barn

Abstract

The invention discloses a direct solar heat supply device of a curing barn and the curing barn with an auxiliary direct solar heat supply function. The direct solar heat supply device of the curing barn comprises light transmission plates, hollow light transmission heat-insulation layers, a solar heat collecting panel and a radiating component; the curing barn with the auxiliary direct solar heat supply function comprises a baking chamber of the curing barn, a heat supply chamber, a circulating fan and a plurality of direct solar heat supply devices of curing barns; and the direct solar heat supply devices of the curing barn are mounted on the top of the baking chamber of the curing barn and can directly replace a roof of the baking chamber of the curing barn to directly supply heat to the baking chamber of the curing barn. The direct solar heat supply device and the curing barn have the advantages that solar energy can be transmitted from the outside of the curing barn to the inside of the curing barn in a one-way manner by the aid of the direct solar heat supply device of the curing barn, the multiple direct solar heat supply devices of the curing barn are mounted on the top of the baking chamber of the curing barn, the thick roof which is commonly adopted for realizing a heat-insulation effect for a curing barn and is high in manufacturing cost is omitted, and effects of effectively and directly utilizing the solar energy and saving baking energy can be realized.

Description

technical field [0001] The invention relates to a solar direct heating device for a barn and a solar auxiliary direct heating barn. Background technique [0002] In the current various industries, there are many practical applications such as the baking and processing of agricultural by-products, such as the intensive curing of tobacco leaves in the tobacco industry, the drying of tea in the tea industry, and the forestry industry. With the continuous development of social economy, there will be more and more barns for drying and processing of Chinese herbal medicines, vegetables, melons and fruits... [0003] At present, the heat energy in the baking process of all kinds of barns is basically obtained through coal combustion, which results in the consumption of a large amount of non-renewable coal resources and the emission of a large amount of harmful smoke and gas into the atmosphere. cause environmental pollution. As solar energy is a renewable clean energy, it is impo...

Problems solved by technology

In CN201938338U, a solar thermal collector is newly added on the top of the smoke chamber and the heating chamber of the barn, and solar energy is used to heat the air in the thermal chamber, and the heated air is communicated with the heating chamber through the air inlet and the air outlet to assist heating; The deficiencies of this utility model have at least three points: one is that the energy-saving flue-cured tobacco room heated by solar energy belongs to the indirect heating mode, and the air in the heat collection chamber heated by solar energy enters the baking chamber to transfer heat energy through circulation, so that a certain amount of The heat energy is inevitably lost to the outside of the baking room, and the utilization efficiency of solar energy is limited; the second is that the flow of the heated air in the heat collection room fails to form a circulation flow with the flow of hot air in the baking room, but passes through the cold air inlet of the heat collection room (in the During baking, the cold air can only enter when dehumidification), and after being heated by the heat collecting chamber, it flows into the baking chamber, which destroys the basic principle of hot air circulation in the baking chamber, and the use of solar energy is only suitable for dehumidification conditions; three. The heat collection chamber is built on the roof of the original baking room (including the baking room and heating room), and the cost is high

In CN20179105U, a solar heating device is newly added on the top of the smoke chamber of the barn to heat the air in the heat collection room by using solar energy. One end of the solar heating device communicates with the baking room through the air inlet pipe, and the other end communicates with the heating chamber through the heat delivery pipe. The room is connected, and at least one fan is added to realize circulation and solar auxiliary heating; the disadvantages of this utility model are at least two points: one is that the fan is added, which increases power consumption while saving fuel; Covering the heat collection chamber, air inlet pipe, and heat delivery pipe on the original roof is costly
