Description

Technical Field

[0001] The technical field to which the utility model belongs is the technical field of solar energy utilization and drying technology. Specifically, it relates to a material drying system that utilizes solar energy for high efficiency, energy saving and flexible adjustment. Background Art

[0002] Drying is a crucial process in modern industrial and agricultural production. Traditional drying methods often rely on fossil fuels such as coal and oil, resulting in high energy consumption and costs, as well as significant environmental pollution. With the growing popularity of sustainable development concepts and the continuous advancement of solar technology, the use of solar energy for drying has become a research hotspot.

[0003] There are many problems with the solar drying equipment currently available on the market. Solar dryers can be divided into direct solar dryers and indirect solar dryers based on whether or not a drying medium is used. Currently, direct solar dryer systems have low thermal efficiency, cannot fully utilize solar energy resources, have slow drying rates, and cannot be applied to large-scale production. While indirect solar dryers have better drying performance, their equipment is complex and has high maintenance costs. Most solar drying equipment also has unsatisfactory drying effects, making it difficult to ensure uniform drying of materials or to flexibly adjust production scales according to actual needs. Therefore, the development of a solar drying system and drying method that is efficient, energy-saving, environmentally friendly, and can be flexibly adjusted is of great practical significance. Summary of the Invention

[0004] The utility model discloses a modular solar drying system with continuous propulsion, which includes a straight-through solar collector 1, a heat pipe fin heating assembly 2, a conveyor belt 3, a hot air material heat exchange chamber 4, a feed channel 5, a discharge channel 6, a full heat exchange assembly 7, a high-temperature resistant fan 8, and a partition 9.

[0005] The feed channel 5 is above the head of the conveyor belt 3 and at the front end of the conveyor belt, and the discharge channel 6 is below the tail of the conveyor belt 3 and at the tail end of the conveyor belt; it is characterized in that the conveyor belt 3 passes through multiple groups of interconnected hot air material heat exchange chambers 4, and the hot air material heat exchange chamber 4 is provided with a high-temperature resistant fan 8, and a heat pipe fin heating component 2 is also provided. There is a partition 9 above the heat pipe fin heating component 2, and the partition 9 separates the hot air and the material; the full heat heat exchange component 7 and the heat pipe fin heating component 2 form a circulation system, and the air enters from the full heat heat exchange component 7, is heated by the heat pipe fin heating component 2, and is discharged from the full heat heat exchange component 7 after the material is dried; the straight-through solar collector 1 is connected to the heat pipe fin heating component 2, and the heat pipe fin heating component 2 is arranged below the conveyor belt 3 and the partition 9, and the conveyor belt 3 is above the partition 9.

[0006] The straight-through solar collector 1 can efficiently absorb solar radiation energy and convert it into heat. This heat is directly passed to the bottom of the conveyor belt through the heat pipe fin heating component 2, providing a heat source for the drying process. The high-temperature resistant fan 8 transports the high-temperature hot air generated by the heat pipe fin heating component 2 to the hot air material heat exchange chamber 4, and performs reverse heat exchange with the wet material. In this process, the high-temperature hot air gradually turns into high-humidity air, and then the high-humidity air enters the full-heat heat exchange component 7, exchanges heat with fresh air and is discharged. The fresh air is fully preheated by the full-heat heat exchange component 7 and enters the system, and exchanges heat with the heat pipe fin heating component again to form high-temperature hot air, thereby completing the gas heating and drying cycle.

[0007] The drying method of the present invention includes the following steps: first, several drying modules are connected to form a long channel; then, a conveyor belt is passed through the entire channel; then, the inlet of the channel is connected to the feed channel, and the outlet is connected to the discharge channel; after that, the heat exchange duct and the full heat exchange component of each module are connected, and then the conveyor belt and the high-temperature resistant fan are powered; finally, the wet material is put into the feed channel, and the dry material is collected in the discharge channel.

[0008] The modular design of this utility model allows multiple solar panels to be flexibly combined into a complete drying production line according to actual needs. It also automatically adjusts the conveyor belt speed and the feed channel feed speed to ensure sufficient drying of the material. This design not only improves energy efficiency and reduces drying costs, but also reduces environmental pollution, providing significant economic and environmental benefits.

[0009] The utility model discloses a continuously propulsive modular solar drying system that combines the features of direct solar dryers and indirect solar dryers. It can not only directly absorb solar energy to obtain higher solar thermal efficiency, but also obtain a stable heat supply through the heat storage characteristics of the heat pipe fin heating component. In addition, the hot air circulation through full heat exchange can further improve the drying effect.

[0010] For example, in the drying of agricultural products, the utility model can quickly and evenly dry a large amount of crops, ensuring the quality and storage period of agricultural products; in the drying of industrial raw materials, it can accurately control the degree of drying, improving the quality of raw materials and subsequent processing performance.

[0011] Patent innovations:

[0012] 1. This utility model uses a straight-through solar collector and heat pipe fin heating components, which can efficiently absorb solar energy and convert it into heat, greatly improving energy utilization efficiency. For example, compared with traditional solar collectors, the straight-through design reduces energy loss during the transmission process.

[0013] 2. The innovative design of the hot air material heat exchange chamber allows the high-temperature hot air and wet materials to move in opposite directions, enhancing the heat exchange effect and ensuring that the materials are fully dried. Taking grain drying as an example, the traditional same-direction heat exchange method may cause some grains to dry unevenly, but the reverse heat exchange of this utility model can effectively avoid this problem.

[0014] 3. The system adopts a modular design, allowing multiple solar panels to be flexibly combined into a complete drying production line to meet different drying tasks of different scales. For example, a small agricultural product processing company can choose a smaller number of modules to form a production line; while a large factory can increase the number of modules to increase drying output.

[0015] 4. It can automatically adjust the conveyor belt speed and the feed channel feed speed, optimizing the drying process in real time according to the material's moisture and dryness, ensuring sufficient drying of the material and improving drying quality. For example, if the material is detected to be too wet, the feed speed will be automatically reduced while the conveyor belt speed will be increased to extend the material's residence time in the drying system.

[0016] 5. The application of full heat exchange components realizes the effective heat exchange between high-humidity air and fresh air, which not only reduces the humidity of the exhaust air, but also fully preheats the fresh air, further improving the energy utilization rate.

[0017] 6. Combining the characteristics of direct solar dryer and indirect solar dryer, it can not only directly absorb solar energy to obtain higher solar thermal efficiency, but also obtain stable heat supply through the heat storage characteristics of heat pipe fin heating components.
