The invention belongs to the technical field of solar energy application, and in particular relates to a refraction ray concentrating continuous operation heat recovery type solar soil disinfection device. Refraction ray concentrating continuous operation regenerative solar soil disinfection device, its technical scheme is: the incident sunlight from above the concentrator converges on the heating tube through the concentrator and the secondary concentrator; The temperature rises under the irradiation and heats the soil in the heating tube; after the soil enters from the feed inlet, it is driven by the conveying blade and moves towards the secondary feed inlet; during the soil movement, it is continuously heated by the sunlight outside the tube and The high-temperature soil inside the heat recovery pipe is heated, and the temperature rises gradually, and reaches the highest temperature when it reaches the secondary feeding port; during the soil heating process, most of the bacteria, nematodes, and weed seeds in the soil are killed; the soil passes through the secondary The secondary feed inlet enters the heat recovery tube and moves towards the discharge port under the action of the driving blade; during the movement, the soil with a higher temperature in the heat recovery tube transfers heat to the soil with a lower temperature outside the heat recovery tube through the wall of the heat recovery tube , the temperature gradually decreases and flows out at the outlet.
Description
technical field [0001] The invention belongs to the technical field of solar heat utilization and agricultural planting, and in particular relates to a refraction ray concentrating continuous operation heat recovery type solar soil disinfection device. Background technique [0002] In the vast areas of northern my country, the temperature in winter is mostly below 0°C, and most of them cannot be planted in the open field. The passive solar greenhouse improves the environmental conditions for vegetable planting, realizes the production of various vegetables in overtime, and improves the utilization rate of land. In the relatively closed space of the greenhouse, the main way for vegetables, fruits and other crops to be infected with pests and diseases is the contact with the soil. Therefore, in order to curb the occurrence of crop diseases and insect pests in the greenhouse and reduce economic losses, it is an effective method to disinfect the soil in the greenhouse. At prese...
