Solar energy hot-air blower

The invention belongs to the field of solar energy intermediate temperature utilization and particularly relates to a solar energy hot-air blower. The solar energy hot-air blower comprises a sealed energy storage tank and a solar thermal collector providing energy for the sealed energy storage tank. The energy storage tank is provided with an outer wall and an inner wall, a vacuum sandwich layer is formed between the outer wall and the inner wall, the energy storage tank is filled with solid heat storage media, after a heat conduction tube is arranged spirally in the solid heat storage media, the two ends of the heat conduction tube are exposed out of the energy storage tank, and the heat conduction media flowing in the heat conduction tube are heated by the solar thermal collector. The energy storage tank is further provided with an air inlet tube and an air outlet tube. Energy collected by the solar thermal collector is transmitted to the heat conduction media in the heat conduction tube and transmitted into the solid heat storage media making contact with the heat conduction tube through flowing of the heat conduction media, so that air entering the energy storage tank from the air inlet tube takes away the energy in the solid heat storage media to form hot air. The solar energy is converted into the hot air for drying well, and the hot-air blower is ingenious in structure, low in cost and particularly suitable for industrialization.
