Description

Technical Field

[0001] This invention relates to the field of solar evaporation and concentration equipment technology, and in particular to an automatic scraping-type solar interface evaporation device. Background Technology

[0002] Solution evaporation and concentration processes are widely used in many industries such as seawater desalination, industrial wastewater treatment, chemical raw material concentration, and food processing. Traditional evaporation methods generally suffer from drawbacks such as high energy consumption and high equipment maintenance costs. Solar photothermal interface evaporation technology, which relies on porous media to achieve capillary liquid supply, can complete water evaporation with the help of solar energy without the need for additional power. It is suitable for various small-scale and decentralized processing scenarios and is now being widely promoted and applied.

[0003] Most common solar interface evaporation devices currently available employ an inclined dome structure, relying primarily on the gravity of the condensate to allow droplets to slide off and be collected. To ensure condensation efficiency, many devices are also equipped with external condensers and cooling medium circulation pipelines to liquefy and collect water vapor.

[0004] However, when water vapor comes into contact with the inner wall of the dome, it gradually condenses into tiny droplets. The droplets formed in the early stage cannot fall off in time due to gravity and will continue to adhere to the light-transmitting wall surface, causing a significant decrease in the light transmittance of the dome, reducing the light utilization rate, restricting the photothermal conversion efficiency, and resulting in a decrease in the overall evaporation effect of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic scraping-type solar interface evaporation device, which solves the technical problem of low photothermal efficiency caused by condensate droplets adhering to the light-transmitting wall surface and reducing light transmittance.

[0006] The technical means employed in this invention are as follows:

[0007] In a first aspect, embodiments of the present invention provide an automatic scraping-type solar interface evaporation device, characterized in that it comprises: The housing has one side that is light-transmitting and the side of the housing opposite to the light-transmitting side that is open. A support plate is disposed inside the housing and near the opening side, and the support plate has multiple water inlets; Multiple photothermal evaporation units are disposed on the support plate and away from the opening side; A scraper assembly, which is slidably disposed within the housing, is used to scrape off condensate on the light-transmitting side; A drive assembly, disposed on the housing, is used to drive the scraper assembly to reciprocate; A drainage component is disposed on one inner wall of the housing and is used to drain the condensate scraped off by the scraper assembly.

[0008] Furthermore, a keel is provided on the side of the support plate near the opening.

[0009] Further, the scraper assembly includes: A pair of slide rails are disposed inside the housing and located between the photothermal evaporation unit and the light-transmitting side; A sliding frame, which is slidably mounted on a pair of slide rails; The water-squeezing component includes a first water-squeezing strip and a second water-squeezing strip. The first water-squeezing strip is disposed on the sliding frame, and the second water-squeezing strip is disposed on one side inner wall of the housing and located above the drainage component and opposite to the first water-squeezing strip. A water-absorbing element is disposed on the sliding frame and located between the first and second water-squeezing strips. The water-absorbing element is used to scrape off condensation on the light-transmitting side during movement.

[0010] Furthermore, the driving component includes: Two sets of transmission components are disposed on the two outer walls opposite to the housing. Each set of transmission components includes multiple shaft brackets, a synchronous shaft, and a pair of synchronous pulleys. The multiple shaft brackets are disposed on the outer wall of the housing, the synchronous shaft is rotatably disposed on the multiple shaft brackets, and the pair of synchronous pulleys are disposed on the synchronous shaft. A pair of synchronous belts, each of the synchronous belts being fitted onto synchronous pulleys in opposite positions on two sets of the transmission components; Two sets of scraper line groups, one end of each set of scraper line groups is connected to two synchronous shafts in the two sets of transmission components, and the other end is connected to the sliding frame; An electric motor is mounted on the housing and its output shaft is connected to one of the synchronous shafts.

[0011] Furthermore, each set of scraper lines includes multiple traction lines, which pass through the side wall of the housing and are connected at one end to the synchronous shaft and at the other end to the sliding frame. A cable stopper is provided on one side of each traction line on the synchronous shaft.

[0012] Furthermore, a support frame is provided on the outer wall of one side of the housing, and the motor is mounted on the support frame.

[0013] Furthermore, drainage outlets are provided at corresponding positions on the drainage component and the housing.

[0014] Furthermore, the bottom of the drainage component is sloped, and the drainage outlet is located on the side wall near the lower end of the bottom of the drainage component.

[0015] Furthermore, the support plate has multiple positioning slots on the side opposite to the opening, and multiple photothermal evaporation units are disposed in the multiple positioning slots.

[0016] Furthermore, the positions of the plurality of positioning grooves correspond to the positions of the plurality of water inlets.

[0017] Compared with the prior art, the present invention has the following advantages: This invention uses a drive component to move a scraper assembly reciprocally within the housing, allowing the scraper assembly to remove condensate from the inner wall of the light-transmitting side of the housing. This reduces the impact of droplet accumulation on the light transmittance of the housing's light-transmitting side and improves photothermal conversion efficiency. By integrating the water collection function into the mechanical structure of the water-absorbing component's adsorption and the water-squeezing component's extrusion, no external condenser or cooling medium circulation system is required, thus reducing the complexity of the device and manufacturing costs. The device is driven solely by a motor within the drive component, reducing the energy consumption required for cooling medium circulation. Both the photothermal evaporation unit and the scraper assembly are located inside the housing without external piping connections, eliminating heat and pressure losses during water vapor transport. The frequency conversion control of the scraper assembly via the motor allows for adaptation to solution concentration requirements under different operating conditions.

[0018] Based on the above reasons, this invention can be widely promoted in fields such as solar evaporation and concentration equipment. Attached Figure Description

[0024] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] Please see Figure 1 and Figure 2 , Figure 1 This is a top view of an automatic scraping-type solar interface evaporation device according to the present invention. Figure 2 This is a first front sectional view of an automatic water-scraping type solar interface evaporation device according to the present invention. Figure 2 The main focus is on showcasing the cross-sectional structure of the support plate.

[0026] This application provides an automatic scraping solar interface evaporation device, including a shell 1, a support plate 4, multiple photothermal evaporation units 3, a scraper assembly, a drive assembly, a drainage component 18, and a water absorption component 8.

[0027] One side of the shell 1 is the light-transmitting side, and the side of the shell 1 opposite to the light-transmitting side is the open side. Specifically, the shell 1 can be a cuboid, cylinder, or other shape, and is a box structure made of a high light-transmitting material (such as quartz glass, polycarbonate, or plexiglass). The top is the light-transmitting side, used to receive sunlight or artificial light. The top of the shell (i.e., the light-transmitting side) can be set horizontally or at a certain angle. When the top of the shell is set at a certain angle, the cross-sectional shape of the entire shell can be trapezoidal (the shell side plates are adapted to the shape of the shell top, and the opposite side plates of the shell are parallel). The scraper assembly is set parallel to the shell top. The bottom of the shell 1 is the open side. When the shell 1 is placed on the water surface, water can enter the interior of the shell 1 through the open side. The thickness can be 10mm. The side walls of the shell 1 and the side walls of the shell 1 and the top of the shell 1 can be connected by structural component 2. The structural component 2 can be made of lightweight corrosion-resistant plastic.

[0028] Please see Figure 3 , Figure 3 This is a top view of the support plate in an automatic scraping solar interface evaporation device according to the present invention.

[0029] A support plate 4 is disposed inside the housing 1 and near the opening side. Multiple water inlets 4-2 are provided on the support plate 4. Specifically, the support plate 4 can be made of a lightweight, corrosion-resistant material (such as polypropylene, polytetrafluoroethylene, or foamed plastic). The support plate 4 is fixed inside the housing 1 near the opening side by fasteners, which can be bolts. Multiple water inlets 4-2 are arrayed on the support plate 4, and the diameter of each water inlet 4-2 can be 5mm. The support plate 4 has buoyancy, allowing it to move the housing 1 up and down with changes in liquid level. When the housing 1 is on the water surface, water can enter the interior of the housing 1 through the multiple water inlets 4-2, thereby maintaining a constant relative position between the upper surface of the photothermal evaporation unit 3 on the support plate 4 and the liquid surface, ensuring stable capillary liquid supply.

[0030] In some embodiments, the photothermal evaporation unit 3 is disposed on the support plate 4 and faces away from the outlet side; specifically, the support plate 4 has a plurality of positioning slots 4-1 on the side facing away from the outlet, and the plurality of photothermal evaporation units 3 are disposed in the plurality of positioning slots 4-1, the plurality of positioning slots 4-1 correspond to the positions of the plurality of water inlets 4-2; the depth of the positioning slots 4-1 can be 2mm, which is used to fix the photothermal evaporation unit 3. When the shell 1 is located on the water surface, water can flow into the photothermal evaporation unit 3 through the plurality of water inlets 4-2 opened on the support plate 4.

[0031] The photothermal evaporation unit 3 can be composed of a porous material matrix and a photothermal coating applied to its surface. The porous material matrix is ​​preferably foam ceramic (such as silicon carbide foam ceramic, alumina foam ceramic, etc.), with a porosity of 30% to 80% and a three-dimensional interconnected pore structure. The lower surface of the photothermal evaporation unit 3 contacts the mother liquor on the support plate 4. Through capillary action, the mother liquor is drawn into the interior of the photothermal evaporation unit 3 and wets the entire unit. The surface of the photothermal evaporation unit 3 serves as the evaporation working surface, heating up under external light source irradiation and promoting water evaporation.

[0032] Please see Figure 4 , Figure 4 This is a bottom view of the support plate in an automatic scraping solar interface evaporation device according to the present invention.

[0033] In some embodiments, a keel 5 is provided on the side of the support plate 4 near the opening; the keel 5 can be made of PC endurance board material and is fixed to the lower surface of the support plate 4 by polytetrafluoroethylene bolts to form a composite floating plate structure with the support plate 4, which is used to limit the excessive deformation of the support plate 4 and ensure the flatness of the support plate 4 and the photothermal evaporation unit 3.

[0034] Please refer to it again. Figure 1 and Figure 2 The scraper assembly is slidably disposed inside the housing 1 to scrape off condensation on the light-transmitting side. Under the action of the drive assembly, the scraper assembly can reciprocate inside the housing 1 to scrape off condensation on the inner wall of the light-transmitting side, preventing condensation from reducing the light transmission performance of the light-transmitting side and improving the utilization rate of light.

[0035] In some embodiments, the scraper assembly includes a pair of slide rails 6, a sliding frame 7, a squeezing element 9, and a suction element 8.

[0036] A pair of slide rails 6 are installed inside the housing 1 and located between the photothermal evaporation unit 3 and the light-transmitting side; the pair of slide rails 6 can be horizontally installed along the length of the housing 1, and the slide rails 6 are linear guide rails, symmetrically arranged on both sides of the inner wall of the housing 1.

[0037] The sliding frame 7 is slidably mounted on a pair of slide rails 6; the sliding frame 7 can straddle the top of the photothermal evaporation unit 3, and its two sides are slidably engaged with the slide rails 6. The sliding frame 7 has a plate-shaped frame structure, is made of lightweight and corrosion-resistant material, and can make reciprocating linear motion along the slide rails 6.

[0038] The water-squeezing component 9 includes a first water-squeezing strip 9-1 and a second water-squeezing strip 9-2. The first water-squeezing strip 9-1 is disposed on the sliding frame 7, and the second water-squeezing strip 9-2 is disposed on one side inner wall of the housing 1, and is located above the drain component 18 and opposite to the first water-squeezing strip 9-1. The first water-squeezing strip 9-1 moves with the sliding frame 7, and the second water-squeezing strip 9-2 is located at the end of the stroke of the sliding frame 7. The water-squeezing strips are elongated and are disposed opposite to the side of the absorbent component 8. When the sliding frame 7 moves the absorbent component 8 to the position of the second water-squeezing strip 9-2, the first water-squeezing strip 9-1 and the second water-squeezing strip 9-2 squeeze the absorbent component 8 to squeeze out the water absorbed inside.

[0039] The absorbent component 8 is mounted on the sliding frame 7 and located between the first squeezing strip 9-1 and the second squeezing strip 9-2. The absorbent component 8 is used to scrape off condensed water on the light-transmitting side during movement. The absorbent component 8 can be a sponge, fixed to the upper part of the sliding frame 7, and is in the shape of a long strip block with its length direction perpendicular to the direction of movement of the sliding frame 7. The upper surface of the sponge is in contact with the light-transmitting side of the housing 1. The sponge is made of a porous material with good hydrophilicity and moderate elasticity (such as polyurethane sponge, polyvinyl alcohol sponge, or cellulose sponge) and is used to absorb the water film and droplets condensed on the inner wall of the light-transmitting side when the sliding frame 7 moves.

[0040] The drive component is mounted on the housing 1 and is used to drive the scraper assembly to move back and forth.

[0041] In some embodiments, the drive assembly includes two sets of transmission assemblies, a pair of synchronous belts 14, two sets of scraper line groups 10, and a motor 17.

[0042] Two sets of transmission components are disposed on the outer walls of the housing 1 on opposite sides. Each set of transmission components includes multiple shaft brackets 12, a synchronous shaft 13 and a pair of synchronous pulleys 15. The multiple shaft brackets 12 are disposed on the outer wall of the housing 1, the synchronous shaft 13 is rotatably disposed on the multiple shaft brackets 12, and the pair of synchronous pulleys 15 are disposed on the synchronous shaft 13.

[0043] Specifically, the shaft bracket 12 can be a bearing housing, with rolling bearings or sliding bearings inside, for supporting the synchronous shaft 13. Two sets of shaft brackets 12 are set on the outer walls of opposite side walls of the housing 1. The synchronous shaft 13 is rotatably mounted on multiple shaft brackets 12 on one side wall of the housing 1, and the length direction of the synchronous shaft 13 is perpendicular to the movement direction of the sliding frame 7. The synchronous pulley 15 is mounted on the synchronous shaft 13, and when the synchronous shaft 13 rotates, it drives the synchronous pulley 15 to rotate synchronously.

[0044] Each synchronous belt 14 is mounted on the synchronous pulleys 15 of the two sets of transmission components, which are positioned opposite each other; the synchronous pulleys 15 and the synchronous belts 14 engage for transmission.

[0045] One end of each of the two sets of scraper line groups 10 is connected to the two synchronous shafts 13 in the two sets of transmission components, and the other end is connected to the sliding frame 7; the scraper line group 10 is used to transmit the rotational motion of the synchronous pulley 15 to the sliding frame 7, so that it reciprocates.

[0046] The motor 17 is mounted on the housing 1 and its output shaft is connected to one of the synchronous shafts 13. A support frame 16 is provided on the outer wall of one side of the housing 1, and the motor 17 is mounted on the support frame 16. The support frame 16 can be U-shaped, and the output shaft can rotate through the support frame 16. The motor 17 can be a stepper motor or a servo motor, and is equipped with a programmable logic controller (PLC) or an embedded microcontroller. The controller controls the start, stop, forward and reverse rotation and speed of the motor 17 according to preset logic (such as timed control, or receiving feedback signals from humidity sensor and liquid level sensor), thereby controlling the reciprocating frequency and speed of the sliding frame 7.

[0047] In some embodiments, each scraper wire assembly 10 includes multiple traction wires. The multiple traction wires pass through the side wall of the housing 1 and are connected at one end to the synchronous shaft 13 and at the other end to the sliding frame 7. A cable stopper 11 is provided on one side of each traction wire on the synchronous shaft 13. The cable stopper 11 is used to adjust the tension of the scraper wire assembly 10 and limit the maximum stroke of the cable to prevent the sliding frame 7 from derailing due to excessive limits.

[0048] Please see Figure 5 and Figure 6 , Figure 5 This is a second main sectional view of an automatic water-scraping type solar interface evaporation device according to the present invention. Figure 5 The main focus is on the cross-sectional structure of drainage component 18. Figure 6 This is a left sectional view of an automatic water-scraping solar interface evaporation device according to the present invention.

[0049] The drain component 18 is disposed on one inner wall of the housing 1 and is used to drain the condensate scraped by the scraper assembly. The drain component 18 can be a cuboid water tank with an open top, disposed on one inner wall of the housing 1 and located on one side of the photothermal evaporation unit 3. The drain component 18 is located below the water squeezing component 9. The drain component 18 and the corresponding position on the housing 1 have drain ports 1-1. The bottom of the drain component 18 is a slope, and the drain ports 1-1 are opened on the side wall near the lower end of the bottom of the drain component 18. This allows the water squeezed out of the water suction component 8 by the water squeezing component 9 to flow into the drain component 18. The water flows from the higher side to the lower side of the bottom of the drain component 18 and is finally discharged from the drain port 1-1 opened on the drain component 18 and the housing 1. The water discharged from the drain component 18 can be guided or collected by a water pipe or a water collection component.

[0050] The specific implementation process of this invention is as follows: The shell 1 is placed in the mother liquor to be concentrated (e.g., a NaCl solution with a mass fraction of 3.5%). Under the buoyancy of the mother liquor, the shell 1 floats on the surface of the mother liquor. The mother liquor flows into the lower surface of the photothermal evaporation unit 3 through multiple water inlets 4-2 opened on the support plate 4. Under capillary action, the mother liquor diffuses along the three-dimensional interconnected channels inside the photothermal evaporation unit 3 to the entire unit, forming a uniform thin liquid film on its surface.

[0051] Place the shell 1 in the sunlight outdoors or use simulated sunlight (such as a xenon lamp with a light intensity of 1000W / m²) for irradiation. The external light source irradiates the surface of the photothermal evaporation unit 3 through the light-transmitting side. The photothermal effect absorbs light energy and converts it into heat energy, which causes the water in the thin liquid film to evaporate. Due to the high humidity inside the shell 1, some water vapor will condense on the inner surface of the shell 1 to form a water film or tiny droplets.

[0052] When the PLC controller issues a control command at a preset time interval (e.g., every 5-30 minutes), the electrode starts and drives the synchronous shaft 13 connected to its output shaft to rotate. The synchronous shaft 13 drives the synchronous pulley 15 to rotate, and the scraper wire group 10 to wind or unwind. Under the traction of the scraper wire group 10, the sliding frame 7 is driven to slide along a pair of slide rails 6. When the sliding frame 7 moves, it drives the first water squeezing strip 9-1 and the water suction element 8 to move. During the movement, the water suction element 8 adsorbs the water film and droplets on the inner surface of the light-transmitting side. When the sliding frame 7 moves to the end of its stroke, the first water squeezing strip 9-1 and the second water squeezing strip 9-2 squeeze the water suction element 8 so that the water absorbed by the water suction element 8 is squeezed out and falls into the drain element 18 below. The water in the drain element 18 is discharged through the drain outlet 1-1 and guided to the water collection element through the water pipe. The controller controls the motor 17 to reverse, and the sliding frame 7 returns to the initial position. During the return process, the sponge absorbs the residual water on the surface again. This process is repeated to achieve water collection.

[0053] This invention uses a drive assembly to move a scraper assembly back and forth inside the housing 1, thereby scraping away condensate on the inner wall of the light-transmitting side of the housing 1. This reduces the impact of droplet accumulation on the light transmittance of the light-transmitting side of the housing 1 and improves the photothermal conversion efficiency. By integrating the water collection function into the mechanical structure of the water-absorbing component 8 (adsorption) and the water-squeezing component 9 (squeezing), there is no need for an external condenser and cooling medium circulation system, thus reducing the complexity of the device and manufacturing costs. The device is driven only by the motor 17 in the drive assembly, reducing the energy consumption of the cooling medium circulation. Both the photothermal evaporation unit 3 and the scraper assembly are located inside the housing 1 without the need for external pipeline connections, eliminating heat and pressure losses during water vapor transportation. The frequency conversion control of the scraper assembly by the motor 17 can adapt to the solution concentration requirements under different operating conditions.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
