Technical Field
[0001] This utility model relates to the field of seawater desalination technology, and in particular to a seawater desalination planting pot. Background Technology
[0002] The world has numerous islands, and areas lacking fresh water are widespread. Currently, vegetable supplies on these islands mainly rely on land-based refrigerated transport or traditional seawater desalination technology. The former is costly and has a long transportation cycle, while the latter requires complex equipment and high energy consumption, making it unsuitable for small-scale farming. In existing technologies, seawater desalination devices are usually separated from the planting system, resulting in low overall efficiency and complex maintenance. Furthermore, traditional planting pots cannot effectively absorb salt, and long-term use can easily lead to soil salinization.
[0003] Therefore, how to integrate seawater desalination and plant cultivation at low cost to solve the problem of plant cultivation difficulties in freshwater-scarce areas is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, this utility model provides a seawater desalination planting pot, comprising an outer transparent tank and an inner transparent tank located at the bottom of the outer transparent tank. The bottom of the inner transparent tank is used to store seawater, and the outer transparent tank is used to collect freshwater. A phenolic foam layer is provided inside the inner transparent tank, which is divided into upper and lower parts: the lower part is a seawater adsorption layer, and the upper part is a black carbonized layer. A purification foam layer and a planting basket are arranged sequentially from bottom to top on the upper part of the outer transparent tank. The planting basket consists of a plant root suspension layer, a planting substrate, and a plant layer, arranged sequentially from bottom to top. The purification foam layer is located above the black carbonized layer.
[0005] Based on the above scheme, furthermore, the planting substrate is matched with the size of the planting basket, and the four sides fit together seamlessly.
[0006] Based on the above scheme, the inner transparent cylinder and the outer transparent cylinder are further made of glass.
[0007] Based on the above solution, the bottom sealing design of the inner and outer double-layer transparent cylinder is further improved.
[0008] Based on the above scheme, the thickness of the phenolic foam layer is further 8-12cm, wherein the seawater adsorption layer accounts for 70%-90% of the thickness of the phenolic foam layer, and the black carbonization layer accounts for 10%-30% of the thickness of the phenolic foam layer.
[0009] Based on the above scheme, furthermore, the adsorbed seawater layer is immersed in seawater at the bottom of the inner transparent tank, and the seawater does not come into contact with the black carbonized layer.
[0010] Furthermore, based on the above scheme, the planting basket is made of polyvinyl chloride material and has ventilation holes on its surface.
[0011] Based on the above scheme, the bottom of the inner transparent cylinder is provided with a removable filter screen, and the top of the outer transparent cylinder is provided with a transparent cover plate.

[0013] Based on the above scheme, the pore size of the purification foam layer is further 50-200μm.
[0014] Compared with existing technologies, this utility model provides a seawater desalination planting pot, in which the adsorbed seawater layer can effectively separate salt and prevent it from entering the planting layer, and the heat absorption characteristics of the black carbonized layer significantly reduce the enthalpy of water evaporation and accelerate the generation of fresh water. Through the synergistic effect of the adsorbed seawater layer and the carbonized layer, seawater desalination is achieved by utilizing natural evaporation and material adsorption, without the need for external energy or complex equipment, which greatly reduces the cost of use. The integrated design simplifies the planting process, and the evaporated fresh water is absorbed and purified by the purification foam layer. The plant roots can directly absorb the purified fresh water, reducing human intervention. It is suitable for freshwater-scarce areas such as islands and deserts, and supports the planting of a variety of vegetables and flowers. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] refer to Figure 1 This utility model provides a seawater desalination planting pot, including an outer transparent tank 20 and an inner transparent tank 10 located at the bottom of the outer transparent tank 20. The bottom of the inner transparent tank 10 is used to store seawater, and the outer transparent tank 20 is used to collect freshwater. A phenolic foam layer 30 is provided inside the inner transparent tank 10. The phenolic foam layer 30 is divided into upper and lower parts. The lower part is a seawater adsorption layer 31, and the upper part is a black carbonized layer 32. A purification foam layer 40 and a planting basket 50 are arranged sequentially from bottom to top on the upper part of the outer transparent tank 20. The planting basket 50 contains a plant root suspension layer 51, a planting substrate 52, and a plant layer 53 sequentially from bottom to top. The purification foam layer 40 is located above the black carbonized layer 32.
[0023] Specifically, the bottom of the inner transparent tank 10 is filled with seawater, and the seawater adsorption layer 31 is immersed in seawater. When the black carbonized layer 32 is exposed to sunlight, it absorbs heat and the seawater evaporates upward. The salt in the seawater remains in the phenolic foam layer 30. After the upward-evaporating water vapor passes through a purification foam layer 40, the pH value of the water vapor becomes neutral and can be absorbed by the plant roots and planting substrate 52. When the plant roots and planting substrate 52 are full of water, the excess water falls back into the outer transparent tank 20.
[0024] In one embodiment, the planting substrate 52 is sized to match the planting basket 50 and fits seamlessly around its perimeter.

[0030] In one embodiment, reference Figure 1 The thickness of the phenolic foam layer 30 is 8-12cm, wherein the seawater adsorption layer 31 accounts for 70%-90% of the thickness of the phenolic foam layer 30, and the black carbonized layer 32 accounts for 10%-30% of the thickness of the phenolic foam layer 30.
[0031] It should be noted that the black carbonized layer 32 is formed by carbonization of the upper part of the phenolic foam layer 30.
[0032] Preferably, the phenolic foam layer 30 has a thickness of 10 cm, the seawater adsorption layer 31 has a thickness of 8 cm, and the black carbonized layer 32 has a thickness of 2 cm.
[0033] The purpose of adopting the above scheme is that the black carbonized layer 32 absorbs heat through solar radiation, reduces the enthalpy of water evaporation, and improves the evaporation efficiency. The phenolic foam layer 30 absorbs seawater. The black carbonized layer 32 and the phenolic foam layer 30 adopt the above-mentioned thickness, which can balance the evaporation efficiency and the water absorption efficiency.
[0034] In one embodiment, the adsorbed seawater layer 31 is immersed in seawater at the bottom of the inner transparent tank 10, and the seawater does not come into contact with the black carbonized layer 32.
[0035] In one embodiment, the planting basket 50 is made of polyvinyl chloride material and has ventilation holes on its surface.
[0036] The purpose of adopting the above scheme is that polyvinyl chloride is a corrosion-resistant and biodegradable material, which can improve the service life of the planting basket 50 and is beneficial to environmental protection. The vents on its surface promote water vapor circulation.
[0037] In one embodiment, reference Figure 2 The bottom of the inner transparent cylinder is provided with a removable filter screen 33, and the top of the outer transparent cylinder is provided with a transparent cover plate 54.
[0038] Using the above solution, the removable filter 33 is used to periodically clean salt deposits, and the transparent cover 54 is used to control the evaporation rate and prevent foreign objects from entering.
[0039] In one embodiment, the density of the phenolic foam layer 30 is 25-30 kg / cm³.
[0040] The purpose of adopting the above scheme is to balance the adsorption efficiency and structural stability of the phenolic foam layer 30.
[0041] In one embodiment, the pore size of the purification foam layer 40 is 50-200 μm.
[0042] The purpose of adopting the above scheme is to ensure that the purification foam layer 40 can fully filter salt and impurities.
[0043] In summary, this utility model provides a seawater desalination planting pot, in which the seawater adsorption layer can effectively separate salt and prevent it from entering the planting layer, and the heat absorption characteristics of the black carbonized layer significantly reduce the enthalpy of water evaporation, accelerating the generation of freshwater. Through the synergistic effect of the seawater adsorption layer and the carbonized layer, seawater desalination is achieved by utilizing natural evaporation and material adsorption, without the need for external energy or complex equipment, greatly reducing the cost of use. The integrated design simplifies the planting process, and the evaporated freshwater is absorbed and purified by the purification foam layer.
