Description

Technical Field

[0001] This utility model relates to the field of distiller equipment, specifically to a dual-function solar distiller. Background Technology

[0002] A solar distiller is a device that uses solar energy to convert non-potable water (such as seawater, sewage, or polluted freshwater) into clean drinking water. Its core principle is to simulate the natural "water cycle" (evaporation-condensation-collection).

[0003] Solar stills utilize solar radiation to heat wastewater, seawater, or brackish water, causing it to vaporize. Components such as sludge, salt, and sediment are retained in the raw water. The vapor is then condensed and collected to obtain pure water. They can also be used for fractional distillation of multi-component solutions. Traditional solar stills have a simple structure, mainly consisting of a water tank filled with raw water and a glass or transparent plastic cover. However, in practical applications, the solar energy utilization rate is low, thus limiting the water production and resulting in poor practicality. Utility Model Content

[0004] To address the technical problems of existing solar distillers having simple structures, low solar energy utilization rates in practical applications, and thus limited water production and poor practicality, this utility model provides a dual-function solar distiller.

[0005] The technical solution adopted by this utility model is as follows: it includes a base, on which a water collection tank is fixedly installed. A drain pipe is fixedly installed on one side of the water collection tank. An installation rod is fixedly connected to the water collection tank. A parabolic reflector is fixedly connected to the outside of the installation rod. A distillation cylinder is also fixedly installed outside the installation rod. A partition ring plate is fixedly connected inside the distillation cylinder. A liquid storage area is formed between the partition ring plate and the installation rod. An evaporation area is formed between the distillation cylinder and the partition ring plate. Cotton cloth is fixedly connected to the inner wall of the distillation cylinder and the surface of the partition ring plate. A dark coating is provided on the outer surface of the distillation cylinder. A condensation assembly is provided on the distillation cylinder.

[0006] Furthermore, a connecting cylinder is fixedly connected to the distillation cylinder, and a light-blocking plate is fixedly installed on the outside of the connecting cylinder.

[0007] By adopting the above technical solutions, the utilization rate of solar energy can be improved.

[0008] Furthermore, the condensation assembly includes a sealing cap threaded onto the connecting cylinder, and a condensation platform is fixedly installed under the sealing cap, the condensation platform being an inverted conical shape.

[0009] By adopting the above technical solution, steam forms water droplets on the condenser platform.

[0010] Furthermore, the mounting rod is hollow and connected to the interior of the water collection tank, with the lower end of the condensation platform located on the axis of the mounting rod.

[0011] By adopting the above technical solution, water droplets enter the water collection tank through the mounting rod.

[0012] Furthermore, the outer surface of the condensation platform is provided with a hydrophobic coating, and a sealing ring is fixedly installed below the sealing cover.

[0013] By adopting the above technical solutions, the efficiency of water vapor condensation can be improved.

[0014] Furthermore, several sets of anti-slip strips are fixedly connected to the outer circumferential surface of the sealing cover, and the several sets of anti-slip strips are evenly arranged in an arc shape.

[0015] By adopting the above technical solutions, the ease of use of the sealing cap is improved.

[0016] Furthermore, the sealing cover and the condensation platform are provided with heat dissipation grooves, a connecting rod is fixedly connected to the sealing cover, and a sunshade is fixedly installed on the connecting rod.

[0017] By adopting the above technical solutions, the condensation effect of the condensation station is guaranteed.

[0018] The beneficial effects of this utility model are: by using a parabolic reflector in conjunction with a distillation cylinder, a connecting cylinder, a sealing cap, and a condenser, parallel sunlight is reflected onto the distillation cylinder to heat the seawater or sewage inside. The resulting water vapor condenses into water droplets on the condenser, thus obtaining clean distilled water. By combining a distillation cylinder with a partition ring plate, cotton cloth, and a deep coating, the distillation cylinder can absorb more solar radiation, reduce reflection loss, and improve the utilization efficiency of solar energy. The capillary force of the cotton cloth continuously transports the water in the storage area to the inner wall of the distillation cylinder. The cotton cloth located on the inner wall of the distillation cylinder forms an evaporation layer, which reduces the residence time of water on the evaporation surface, lowers the heat capacity, and accelerates the evaporation of water, thereby improving the distillation function of the device. By using a sealing cap in conjunction with a condenser platform, a hydrophobic coating, a sealing ring, a heat dissipation groove, and a sunshade, the water vapor generated by the distillation cylinder is prevented from escaping. At the same time, the temperature difference between the water vapor and the condenser platform is maintained, thereby improving the condensation efficiency of the condenser platform and thus enhancing the condensation function of the device.

They are only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 The present invention will be further described below.

[0024] To address the problems existing in the background art, this application proposes the following technical solution: A base 1 is included, a water collection tank 2 is fixedly installed on the base 1, a drain pipe 3 is fixedly installed on one side of the water collection tank 2, an installation rod 4 is fixedly connected to the water collection tank 2, a parabolic reflector 5 is fixedly connected to the outside of the installation rod 4, a distillation cylinder 6 is also fixedly installed outside the installation rod 4, a partition ring plate 7 is fixedly connected inside the distillation cylinder 6, a liquid storage area 8 is formed between the partition ring plate 7 and the installation rod 4, an evaporation area 9 is formed between the distillation cylinder 6 and the partition ring plate 7, cotton cloth 13 is fixedly connected to the inner wall of the distillation cylinder 6 and the surface of the partition ring plate 7, a dark coating 14 is provided on the outer surface of the distillation cylinder 6, and a condensation assembly is provided on the distillation cylinder 6.

[0025] Seawater or sewage is added to the storage area 8. Sunlight shines on the parabolic reflector 5. The parabolic shape of the reflector 5 reflects and focuses the parallel sunlight onto the surface of the distillation cylinder 6, so that the light spot covers the surface area of ​​the distillation cylinder 6 and the energy is evenly distributed, avoiding local overheating or energy waste. The capillary force of the cotton cloth 13 continuously transports the water in the storage area 8 to the inner wall of the distillation cylinder 6. The cotton cloth 13 on the inner wall of the distillation cylinder 6 forms an evaporation layer, reducing the residence time of water on the evaporation surface, reducing the heat capacity, thereby accelerating the evaporation of water and improving the distillation effect of seawater or sewage. The evaporated water vapor forms water droplets on the condensation component and is then collected in the water collection tank 2. The dark coating 14 uses a black or dark coating (such as a carbon-based or metal oxide coating) to absorb more solar radiation and reduce reflection loss, thereby improving the utilization effect of solar energy and thus improving the practicality of the device.

[0026] To further explain, a connecting cylinder 10 is fixedly connected to the distillation cylinder 6, and a light-blocking plate 19 is fixedly installed on the outside of the connecting cylinder 10.

[0027] The connecting cylinder 10 provides installation conditions for the condenser assembly and the light-blocking plate 19. When the light spot reflected by the parabolic reflector 5 exceeds the top of the distillation cylinder 6, the light-blocking plate 19 blocks and reflects the light spot that exceeds the range, so that it is projected onto the surface of the distillation cylinder 6. The setting of the light-blocking plate 19 optimizes the light-gathering effect at the edge of the light spot, reduces the interference of scattered light, controls the distribution of light spot energy, and at the same time avoids overheating of the condenser assembly located on the connecting cylinder 10, thereby improving the utilization effect of solar energy.

[0028] To further explain, the condenser assembly includes a sealing cap 11 threaded onto the connecting cylinder 10, and a condenser platform 12 fixedly installed under the sealing cap 11. The condenser platform 12 is configured in an inverted conical shape.

[0029] The condenser assembly and the connecting cylinder 10 are detachably connected by a threaded connection, making it easy to remove the condenser assembly from the connecting cylinder 10. Water is added to the liquid storage area 8 or the concentrated seawater and impurities in the liquid storage area 8 after evaporation are cleaned. The water vapor generated by the heating of the cotton cloth 13 evaporation layer on the inner wall of the distillation cylinder 6 by solar energy rises to the sealing cover 11. The water vapor condenses into a water film on the surface of the condenser platform 12. The water film flows along the surface of the condenser platform 12 and forms water droplets at the lowest point of the condenser platform 12, resulting in clean distilled water.

[0030] To further clarify, the mounting rod 4 is hollow and is connected to the interior of the water collection tank 2. The lower end of the condensation platform 12 is located on the axis of the mounting rod 4.

[0031] Water droplets formed at the lowest point of the condensation platform 12 fall due to gravity. The water droplets fall into the water collection tank 2 through the hollow channel of the mounting rod 4. The clean distilled water obtained is collected in the water collection tank 2, and the water collected in the water collection tank 2 can be discharged through the drain pipe 3.

[0032] Furthermore, the outer surface of the condenser platform 12 is provided with a hydrophobic coating 15, and a sealing ring 16 is fixedly installed below the sealing cover 11.

[0033] The hydrophobic coating 15 is made of copper hydroxide (Cu(OH)2) nano-coating. By increasing the surface area and hydrophobicity of the condensing platform 12, and by reducing the surface energy or constructing micro-nano structures, the film condensation (liquid water film covering the surface, hindering heat exchange) is transformed into droplet condensation (droplets roll off rapidly, reducing thermal resistance). This improves the condensation effect of water vapor on the surface of the condensing platform 12. The sealing ring 16 is made of an elastic material, such as rubber. The elasticity of the sealing ring 16 improves the sealing performance of the sealing cover 11 after installation, preventing water vapor from escaping from the distillation cylinder 6 and improving the distillation efficiency of seawater or sewage.

[0034] Furthermore, several sets of anti-slip strips 18 are fixedly connected to the outer circumference of the sealing cover 11, and the several sets of anti-slip strips 18 are evenly arranged in an arc shape.

[0035] The anti-slip strip 18 increases the friction between the hand and the outer circumference of the sealing cap 11, making the process of tightening and loosening the sealing cap 11 easier and more convenient.

[0036] Furthermore, heat dissipation grooves 17 are provided on the sealing cover 11 and the condensation platform 12, and a connecting rod 20 is fixedly connected to the sealing cover 11, and a sunshade 21 is fixedly installed on the connecting rod 20.

[0037] The heat exchange effect between the sealing cover 11 and the condenser platform 12 and the outside world is increased by the heat dissipation groove 17, which reduces the temperature of the condenser platform 12 and increases the temperature difference between the condenser platform 12 and water vapor, thereby improving the condensation efficiency of the condenser platform 12. The setting of the sunshade 21 avoids direct sunlight on the sealing cover 11, which would cause the temperature of the condenser platform 12 to be too high, and ensures the temperature difference between the condenser platform 12 and water vapor.

[0038] The parabolic reflector 5, dark coating 14, hydrophobic coating 15, and sealing ring 16 of this utility model dual-function solar distiller are commercially available and are existing technologies. Skilled personnel in the industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0039] The specific operation is as follows: Add seawater or sewage into the storage area 8, tighten the condenser assembly onto the connecting cylinder 10, and let sunlight shine on the parabolic reflector 5. The parabolic shape of the parabolic reflector 5 reflects and focuses the parallel sunlight onto the surface of the distillation cylinder 6, so that the light spot covers the surface area of ​​the distillation cylinder 6. The capillary force of the cotton cloth 13 continuously transports the water in the storage area 8 to the inner wall of the distillation cylinder 6. The cotton cloth 13 on the inner wall of the distillation cylinder 6 forms an evaporation layer. The reflected sunlight raises the surface temperature of the distillation cylinder 6, accelerating the formation of water vapor from the water on the cotton cloth 13. The generated water vapor rises to the surface of the condenser platform 12 and condenses into a water film. The water film flows along the surface of the condenser platform 12 and forms water droplets at the lowest point of the condenser platform 12. The water droplets fall due to gravity and fall into the water collection tank 2 through the hollow channel of the mounting rod 4. The clean distilled water obtained is collected in the water collection tank 2, and the water collected in the water collection tank 2 can be discharged through the drain pipe 3.

The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
