Description

Technical Field

[0001] The present application relates to the technical field of seawater desalination, and in particular to a seawater desalination treatment device and a processing technology thereof. Background Art

[0002] With the continued growth of the global population and economic development, the demand for freshwater resources is increasing. However, freshwater resources on Earth only account for a tiny proportion of the total water resources and are extremely unevenly distributed, leaving many regions facing severe freshwater shortages. Meanwhile, oceans cover approximately 71% of the Earth's surface and contain an extremely rich supply of seawater. Effectively converting seawater into usable freshwater would undoubtedly significantly alleviate the global freshwater shortage and be crucial for ensuring water availability for domestic use, industrial use, and agricultural irrigation.

[0003] Traditional multi-stage flash (MSF) technology is a widely used thermal desalination method. It heats seawater to a certain temperature, then instantly evaporates it in multiple flash chambers with gradually decreasing pressures. The water vapor is then condensed to produce fresh water. However, this technology has significant drawbacks. Maintaining the seawater heating process requires significant amounts of thermal energy, typically using steam or electric heating. This not only consumes significant energy and increases production costs, but also fails to meet the requirements of low-energy production.

[0004] Therefore, designing a seawater desalination device that reduces energy consumption and lowers costs is an urgent problem to be solved. Summary of the Invention

[0005] In order to design a seawater desalination treatment device that reduces energy consumption and lowers costs, the present application provides a seawater desalination treatment device and a processing technology thereof.

[0006] The present application provides a seawater desalination treatment device that adopts the following technical solutions: A seawater desalination treatment device includes a frame, an inclined support plate is provided on the frame, a receiving cavity and a connecting groove are respectively opened on both sides of the inclined support plate, a water inlet pipe extends to the top of the receiving cavity, and multiple groups of treatment devices for desalinating seawater are provided on the support plate; the treatment device includes a heat collecting pipe, both ends of the heat collecting pipe are respectively connected to the receiving cavity and the connecting groove, the frame is connected to the water inlet pipe for guiding seawater into the connecting groove, a reflector is provided on the side of the support plate close to the heat collecting pipe, the reflector is arranged in an arc shape, and the reflector is located on the outside of the heat collecting pipe, a ventilation pipe is fixedly connected to the heat collecting pipe, one end of the ventilation pipe extends out of the receiving cavity, and the other end extends out of the connecting groove, that is, the ventilation pipe passes through the interior of the heat collecting pipe, and a crystal rope woven from porous fibers is provided in the heat collecting pipe.

[0007] By adopting the above technical solution, when the user uses it, the seawater is passed into the heat collecting tube. The reflector is used to increase the heat collecting area by reflecting the scattered sunlight and concentrating it on the heat collecting tube. At the same time, it can adjust the direction of light to increase the heat collecting area of ​​the heat collecting tube and improve the heat collecting efficiency of the heat collecting tube. The heat collecting tube is heated rapidly, and the seawater flowing through the heat collecting tube is heated. By heating the seawater, the water in the seawater gradually evaporates. When the seawater is heated to the boiling point of water (about 100℃), the water obtains enough kinetic energy to overcome the surface tension and changes from liquid to gas to form water vapor. The water vapor is adsorbed on the preheating tube. On the outer wall, air passes through the ventilation pipe. Since the temperature of the air is much lower than that of the heated seawater, water vapor exchanges heat with the low-temperature medium air. When the steam temperature drops below the dew point, it re-liquefies to form fresh water. At the same time, the concentration of salts in the seawater continues to increase. When the concentration of salts reaches an oversaturated state, the solute will crystallize out of the solution. The crystalline rope woven with holes is hydrophilic inside and hydrophobic on the surface. When immersed in salty water, water will be adsorbed to the inside of the rope through capillary action, and then the water will evaporate, leaving the salt, realizing the largest desalination treatment of seawater and separating the fresh water from the seawater.

[0008] Optionally, a preheating pipe is fixedly connected to the heat collecting pipe, one end of the preheating pipe extends to the top of the frame and communicates with the water inlet pipe, and the other end extends into the connecting groove. The preheating pipe is located near the top wall of the heat collecting pipe.

[0009] By adopting the above technical solution, when the user uses it, the heat from the side wall of the heat collecting tube heats the seawater flowing through the preheating tube, thereby increasing the temperature of the seawater entering the heating tube, further facilitating the heating and evaporation of the seawater, and desalinating the seawater, thereby improving the efficiency of the seawater desalination treatment. In addition, the water vapor with large heating and evaporation is adsorbed on the outer wall of the preheating tube. Due to the temperature difference between the seawater temperature and the water vapor in the preheating tube, the water vapor on the side wall of the preheating tube is condensed into fresh water, thereby realizing the separation of fresh water in the seawater, increasing the attachment surface of the water vapor, and further improving the efficiency of the seawater desalination.

[0010] Optionally, the frame is fixedly connected to a feed box at the top of the connecting groove, the feed box is used to carry activated carbon particles, and the bottom of the feed box is fixedly connected to a discharge pipe, which extends to a position of the connecting groove close to the connecting pipe.

[0011] By adopting the above technical solution, when users use it, the activated carbon particles enter the heat collecting tubes together with the seawater. On the one hand, the main function of the activated carbon particles is to adsorb pollutants such as suspended particles, organic matter, pigments and odors in the water, thereby improving the water quality. The activated carbon particles can effectively remove these impurities in the water through their porous structure and strong adsorption capacity, making the water clear and transparent; on the other hand, the activated carbon particles and water mix and flow along the heat collecting tubes. The activated carbon particles stir the seawater, facilitating the precipitation of salt in the seawater.

[0012] Optionally, a winding roller is rotatably connected in the accommodating chamber, and the crystallization rope is wound around the winding roller. Two tensioning rollers are rotatably connected to the side of the frame close to the connecting hole. The crystallization rope is arranged along the length direction of the frame from the winding roller, and the crystallization rope passes around the two tensioning rollers in turn. A through hole for the crystallization rope to pass through is opened on the heat collecting tube. After passing around the tensioning roller, the crystallization rope passes through the heat collecting tube, and the crystallization rope is tensioned between the winding roller and the tensioning roller.

[0013] By adopting the above technical solution, when the user uses it, the crystallization rope is tensioned between the winding roller and the tensioning roller. The rotation of the winding roller can drive the crystallization rope to slide, and the crystallization rope passes through the heat collecting tube. The crystals precipitated in the seawater are adsorbed on the crystallization rope; the crystallization rope is woven from porous fibers. This rope is hydrophilic inside and hydrophobic on the surface. When immersed in salt water, water will be adsorbed into the inside of the rope through capillary action, and then the water will evaporate, leaving salt. As the water continues to evaporate, the salt concentration gradually increases, and eventually salt crystals are formed on the rope.

[0014] Optionally, a material receiving box is fixedly connected to the accommodating chamber, the material receiving box is located below the heat collecting tube, the material receiving box is used to collect seawater and activated carbon particles, a collection box is fixedly connected to the accommodating chamber, the collection box is provided with a through hole for the crystallization rope to pass through, and a plurality of scrapers are fixedly connected to the collection box, the scrapers are provided with holes for the crystallization rope to pass through.

[0015] By adopting the above technical solution, when the user uses it, the material receiving box is located below the heat collecting tube, the material collecting box is used to collect seawater and activated carbon particles flowing out of the heat collecting tube, the scraper is used to scrape the salt off the crystallization rope, and the material receiving box collects the salt.

[0016] Optionally, the rack is provided with a collecting pipe in the accommodating cavity, and a water collecting plate is fixedly connected to the side of the heat collecting pipe close to the accommodating cavity. The water collecting plate is located below the ventilation pipe, and the water collecting plate is arranged in an arc shape. The two sides of the water collecting plate are inclined downward, and the two sides of the water collecting plate are fixedly connected to the side walls of the heat collecting pipe. Two water pipes are fixedly connected to the side walls of the rack, and the water pipes extend into the heat collecting pipe and extend to both sides of the water collecting plate.

[0017] By adopting the above technical solution, when the user uses it, the distilled water collected on the side walls of the ventilation pipe and the preheating pipe flows into the water collecting plate, and the distilled water flows into the collection pipe through the water guide pipe to be collected.

[0018] Optionally, a filter box is fixedly connected to the water inlet pipe, and a filter screen is provided in the filter box.

[0019] By adopting the above technical solution, when the user uses it, the filter is used to perform preliminary filtration on the seawater to remove some large impurities such as suspended matter and sediment in the seawater.

[0020] A processing technology for a seawater desalination treatment device comprises the following steps: S1. Filtration: The water inlet pipe leads the seawater into the filter box, which is equipped with a filter screen. The filter screen is used to perform preliminary filtration on the seawater to remove some large impurities such as suspended matter and silt in the seawater; S2. Preheating: Seawater enters the preheating tube through the water inlet pipe. The heat from the top of the heat collecting tube heats the seawater, raising its temperature. S3. Purification: The activated carbon particles in the feed box enter the heat collecting tubes together with the seawater. The main function of the activated carbon particles is to absorb pollutants such as suspended particles, organic matter, pigments, and odors in the water, thereby improving the water quality. The activated carbon particles can effectively remove these impurities in the water through their porous structure and strong adsorption capacity, making the water clear and transparent. S4. Heating and evaporating water vapor: The reflectors reflect scattered sunlight and concentrate it on the heat collecting tubes, causing the tubes to heat up rapidly and heating the seawater flowing through them. By heating the seawater, the water in the seawater gradually evaporates, while the concentration of salts continues to increase. S5. Condensing fresh water: The seawater is heated to a liquid state and then converted into a gaseous state, forming water vapor. The water vapor is adsorbed on the outer walls of the preheating tube and the outer walls of the ventilation pipe. Air passes through the ventilation pipe. Since the air temperature is much lower than that of the heated seawater, the water vapor exchanges heat with the low-temperature medium air. When the steam temperature drops below the dew point, it re-liquefies to form fresh water, which flows down the ventilation pipe. Similarly, the temperature difference between the seawater temperature and the water vapor in the preheating pipe causes the water vapor on the side walls of the preheating pipe to condense into fresh water, thus achieving fresh water separation from the seawater. Then, the distilled water collected on the side walls of the ventilation pipe and the preheating pipe flows onto the water collection plate. The distilled water flows into the collection pipe through the water guide pipe and is collected. S6. Crystallization: The crystallization rope passes through the heat collecting tube and is stretched between the winding roller and the tensioning roller. The rotation of the winding roller can drive the crystallization rope to slide. The crystallization rope passes through the heat collecting tube and the crystals precipitated in the seawater are adsorbed on the crystallization rope. As the water evaporates, the salt concentration gradually increases and eventually salt crystals are formed on the rope. After a period of time, the winding roller is rotated and the crystallization rope passes through the scraper, which scrapes the salt off the crystallization rope and the material box collects the salt.

In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0026] Example 1: The present application discloses a seawater desalination device, referring to Figure 1, including a frame 1, a support plate 11 is provided on the frame 1, the support plate 11 is obliquely arranged on the frame 1, the support plate 11 is inclined upward, and a plurality of treatment devices 2 for desalinating seawater are provided on the support plate 11. The treatment devices 2 are evenly spaced along the length direction of the support plate 11, and each treatment device 2 is arranged along the inclined direction of the support plate 11.

[0027] Reference Figure 2 A water inlet pipe 12 is provided at the bottom of the support plate 11 and runs along the length of the support plate 11. A filter box 13 is fixedly connected to the water inlet pipe 12. The filter box 13 houses a filter screen that performs preliminary filtration of the seawater, removing large impurities such as suspended matter and silt. A receiving cavity 14 and a connecting groove 15 are provided on either side of the inclined support plate 11. The water inlet pipe 12 extends to the top of the receiving cavity 14 and runs along its length.

[0028] The processing device 2 includes a heat collecting pipe 21, which is arranged along the inclined direction of the support plate 11. The heat collecting pipe 21 is used to absorb solar energy. The outer wall of the heat collecting pipe 21 is coated with a heat absorbing coating, which can absorb solar radiation energy and convert it into heat energy. A preheating pipe 22 is fixedly connected to the heat collecting pipe 21. One end of the preheating pipe 22 extends to the top of the frame 1 and is fixedly connected to the water inlet pipe 12. The preheating pipe 22 is connected to the water inlet pipe 12, and the other end extends to the connecting groove 15. The preheating pipe 22 is connected to the water inlet pipe 12. The heat pipe 22 is located near the top wall of the heat collecting pipe 21. The heat from the side wall of the heat collecting pipe 21 heats the seawater flowing through the preheating pipe 22, thereby increasing the temperature of the seawater. A connecting pipe 23 is fixedly connected to the connecting groove 15, and the connecting pipe 23 connects and fixes the connecting groove 15 and the heat collecting pipe 21. Seawater enters the preheating pipe 22 through the water inlet pipe 12 and is heated. The heated seawater flows into the connecting groove 15. The preheated seawater in the connecting groove 15 flows into the heat collecting pipe 21 through the connecting pipe 23.

[0029] A reflector 24 is installed on the side of the support plate 11 near the heat collecting tube 21. This curved reflector 24 is located outside the heat collecting tube 21. By reflecting scattered sunlight and concentrating it onto the tube 21, the reflector 24 increases the heat collection area. It also redirects the light, increasing the heat collection area and improving the heat collection efficiency of the tube 21. This rapidly heats the tube 21, heating the seawater flowing through it. This heating gradually evaporates the water in the seawater, increasing the concentration of salts. When the salt concentration reaches supersaturation, solutes crystallize out of solution. The reflector 24 is coated with a silver mirror layer with extremely high reflectivity, maximizing sunlight reflection. In a solar energy collection system, the high reflectivity of the silver mirror layer ensures that more sunlight is reflected onto the heat collecting tube 21, thereby improving the photoelectric conversion efficiency and the heating efficiency of the heat collecting tube 21.

[0030] Reference Figure 3 and Figure 4 In order to purify seawater, the frame 1 is fixedly connected to a feed box 25 at the top of the connecting groove 15. The feed box 25 is used to carry activated carbon particles. The bottom of the feed box 25 is fixedly connected to a discharge pipe 251. The discharge pipe 251 extends into the connecting groove 15, and the bottom of the discharge pipe 251 is located at a position of the connecting groove 15 close to the connecting pipe 23, so that the activated carbon particles and the seawater enter the heat collecting pipe 21 together. On the one hand, the main function of the activated carbon particles is to adsorb pollutants such as suspended particles, organic matter, pigments and odors in the water, thereby improving the water quality. The activated carbon particles can effectively remove these impurities in the water through their porous structure and strong adsorption capacity, making the water clear and transparent; on the other hand, the activated carbon particles and water are mixed and flow along the heat collecting pipe 21. The activated carbon particles stir the seawater, which facilitates the precipitation of salt in the seawater.

[0031] A ventilation pipe 26 is fixedly connected to the heat collecting pipe 21. One end of the ventilation pipe 26 extends out of the accommodating cavity 14, and the other end extends out of the connecting groove 15. That is, the ventilation pipe 26 passes through the interior of the heat collecting pipe 21 and is located between the preheating pipe 22 and the inner wall of the heat collecting pipe 21. When the seawater is heated to the boiling point of water (about 100°C), the water obtains sufficient kinetic energy to overcome surface tension and transforms from liquid to gas to form water vapor. The water vapor is adsorbed on the outer wall of the preheating pipe 22 and the outer wall of the ventilation pipe 26. Air passes through the ventilation pipe 26. Because the temperature of the air is much lower than that of the heated seawater, the water vapor exchanges heat with the low-temperature medium air. When the steam temperature drops below the dew point, it reliquefies to form fresh water, which flows downward along the ventilation pipe 26. Similarly, the temperature difference between the seawater temperature and the water vapor in the preheating pipe 22 causes the water vapor on the side wall of the preheating pipe 22 to condense into fresh water, realizing the separation of fresh water from seawater. Two air guide plates 261 are provided on the side walls of the rack 1 located in the accommodating chamber 14. The air guide plates 261 are tilted outward. The guide plates can guide the air into the ventilation pipe 26, thereby increasing the air circulation in the ventilation pipe 26 and having a better effect on the condensation of water vapor outside the ventilation pipe 26.

[0032] Reference Figure 3 and Figure 5 The rack 1 is located in the accommodating chamber 14 and is provided with a collecting pipe 27. A water collecting plate 272 is fixedly connected to the side of the heat collecting pipe 21 close to the accommodating chamber 14. The water collecting plate 272 is located below the ventilation pipe 26. Both sides of the water collecting plate 272 are fixedly connected to the side walls of the heat collecting pipe 21. Two water pipes 271 are fixedly connected to the side walls of the rack 1. The water pipes 271 extend into the heat collecting pipe 21. The water collecting plate 272 is arranged in an arc shape, and both sides of the water collecting plate 272 are inclined downward. The water pipes 271 extend to both sides of the water collecting plate 272; the distilled water collected on the side walls of the ventilation pipe 26 and the side walls of the preheating pipe 22 flows into the water collecting plate 272, and the distilled water flows into the collecting pipe 27 through the water pipe 271 and is collected.

[0033] In order to facilitate the collection of salt precipitated in seawater, a winding roller 28 is rotatably connected in the accommodating chamber 14, and a plurality of crystallization ropes 281 are wound around the winding roller 28. Two tensioning rollers 282 are rotatably connected to the side of the frame 1 close to the connecting hole 211. The crystallization ropes 281 are arranged along the length direction of the frame 1 from the winding roller 28. The crystallization ropes 281 pass through the two tensioning rollers 282 in sequence. A through hole 211 is opened on the heat collecting tube 21 for the crystallization ropes 281 to pass through. The crystallization ropes 281 pass around the tensioning rollers. After passing through the heat collecting tube 21, the crystallization rope 281 is stretched between the take-up roller 28 and the tensioning roller 282. The rotation of the take-up roller 28 drives the crystallization rope 281 to slide, allowing the rope 281 to pass through the heat collecting tube 21. Crystals precipitated from the seawater are adsorbed on the crystallization rope 281. The crystallization rope 281 is woven from porous fibers. This rope is hydrophilic on the inside and hydrophobic on the surface. When immersed in salt water, water is attracted to the rope through capillary action. The water then evaporates, leaving behind the salt. As the water evaporates, the salt concentration gradually increases, eventually forming salt crystals on the rope.

[0034] A material receiving box 283 is fixedly connected to the accommodating chamber 14, and the material receiving box 283 is located below the heat collecting tube 21. The material collecting box 29 is used to collect seawater and activated carbon particles flowing out of the heat collecting tube 21; a material collecting box 21 is fixedly connected to the accommodating chamber 14, and a through hole is provided on the material collecting box 29 for the crystallization rope 281 to pass through. A plurality of scrapers 291 are fixedly connected to the material collecting box 29, and holes are provided on the scrapers 291 for the crystallization rope 281 to pass through. The scrapers 291 scrape the salt on the crystallization rope 281, and the material receiving box 283 collects the salt.

[0035] Example 2: A processing technique for a seawater desalination treatment device according to the second embodiment of the present application, which uses the seawater desalination treatment device according to the first embodiment, includes the following steps: S1. Filtration: The water inlet pipe 12 introduces seawater into the filter box 13. The filter box 13 is provided with a filter screen for preliminary filtration of the seawater to remove some large impurities such as suspended matter and sediment in the seawater.

[0036] S2. Preheating: Seawater enters the preheating pipe 22 through the water inlet pipe 12. The heat from the top of the heat collecting pipe 21 heats the seawater, thereby increasing the seawater temperature.

[0037] S3. Purification: The activated carbon particles in the feed box 25 enter the heat collecting tube 21 together with the seawater. The main function of the activated carbon particles is to absorb pollutants such as suspended particles, organic matter, pigments, and odors in the water, thereby improving the water quality. The activated carbon particles can effectively remove these impurities in the water through their porous structure and strong adsorption capacity, making the water clear and transparent.

[0038] S4. Heating and evaporating water vapor: The reflector 24 reflects the scattered sunlight and concentrates it on the heat collecting tube 21, causing the heat collecting tube 21 to heat up rapidly, heating the seawater flowing through the heat collecting tube 21. By heating the seawater, the water in the seawater gradually evaporates, and the concentration of salts continues to increase.

[0039] S5. Condensing fresh water: The seawater is heated to a liquid state and then converted into a gaseous state to form water vapor. The water vapor is adsorbed on the outer wall of the preheating tube 22 and the outer wall of the ventilation tube 26. Air passes through the ventilation tube 26. Since the temperature of the air is much lower than that of the heated seawater, the water vapor exchanges heat with the low-temperature medium air. When the steam temperature drops below the dew point, it re-liquefies to form fresh water, which flows downward along the ventilation tube 26. Similarly, the temperature difference between the seawater temperature and the water vapor in the preheating tube 22 causes the water vapor on the side wall of the preheating tube 22 to condense into fresh water, thus achieving the separation of fresh water from the seawater. Then, the distilled water collected on the side walls of the ventilation tube 26 and the preheating tube 22 flows into the water collection plate 272, and the distilled water flows into the collection tube 27 through the water guide pipe 271 and is collected.

[0040] S6. Crystallization: The crystallization rope 281 passes through the heat collecting tube 21. The crystallization rope 281 is stretched between the winding roller 28 and the tensioning roller 282. The rotation of the winding roller 28 can drive the crystallization rope 281 to slide. The crystallization rope 281 passes through the heat collecting tube 21. Crystals precipitated from the seawater are adsorbed on the crystallization rope 281. As the water evaporates, the salt concentration gradually increases, and eventually salt crystals are formed on the rope. After a period of time, the winding roller 28 is rotated, and the crystallization rope 281 passes through the scraper 291. The scraper 291 scrapes the salt off the crystallization rope 281, and the material receiving box 283 collects the salt.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.

8. A processing technology for a seawater desalination treatment device, applied to the seawater desalination treatment device according to any one of claims 1 to 7, characterized in that: The steps include: S1, filtration: The water inlet pipe (12) guides the seawater into the filter box (13), and a filter screen is provided in the filter box (13). The filter screen is used to perform preliminary filtration on the seawater to remove some large impurities such as suspended matter and silt in the seawater; S2, preheating: seawater enters the preheating pipe (22) through the water inlet pipe (12), and the heat from the top of the heat collecting pipe (21) heats the seawater, raising the seawater temperature; S3, purification: The activated carbon particles in the feed box (25) enter the heat collecting tube (21) together with the seawater. The main function of the activated carbon particles is to absorb pollutants such as suspended particles, organic matter, pigments and odors in the water, thereby improving the water quality. The activated carbon particles can effectively remove these impurities in the water through their porous structure and strong adsorption capacity, making the water clear and transparent; S4. Heating and evaporating water vapor: The reflector (24) reflects the scattered sunlight and concentrates it on the heat collecting tube (21), causing the heat collecting tube (21) to heat up rapidly, thereby heating the seawater flowing through the heat collecting tube (21). By heating the seawater, the water in the seawater gradually evaporates, while the concentration of salts continues to increase; S5. Condensing fresh water: The seawater is heated to a liquid state and then converted into a gaseous state to form water vapor. The water vapor is adsorbed on the outer wall of the preheating tube (22) and the outer wall of the ventilation tube (26). Air passes through the ventilation tube (26). Since the temperature of the air is much lower than that of the heated seawater, the water vapor exchanges heat with the low-temperature medium air. When the steam temperature drops below the dew point, it is re-liquefied to form fresh water. The fresh water flows downward along the ventilation tube (26). Similarly, a temperature difference is formed between the seawater temperature and the water vapor in the preheating tube (22), causing the water vapor on the side wall of the preheating tube (22) to condense into fresh water, thereby achieving the separation of fresh water from the seawater. Then, the distilled water collected on the side wall of the ventilation tube (26) and the side wall of the preheating tube (22) flows into the water collecting plate (272). The distilled water flows into the collecting tube (27) through the water guide tube (271) and is collected. S6. Crystallization: The crystallization rope (281) passes through the heat collecting tube (21). The crystallization rope (281) is stretched between the winding roller (28) and the tensioning roller (282). The rotation of the winding roller (28) can drive the crystallization rope (281) to slide. The crystallization rope (281) passes through the heat collecting tube (21). Crystals precipitated from the seawater are adsorbed on the crystallization rope (281). As the water evaporates, the concentration of salt gradually increases, and eventually salt crystals are formed on the rope. After a period of time, the winding roller (28) is rotated, and the crystallization rope (281) passes through the scraper (291). The scraper (291) scrapes the salt on the crystallization rope (281), and the material receiving box (283) collects the salt.
