Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 5 , the present invention provides a technical solution: A steam-water separation device for seawater desalination, including a separation tank 1. On one side of the inner cavity of the separation tank 1, there is a treatment cavity 5 for filtering seawater. At the upper end of the treatment cavity 5, there is a water inlet 2. In the inner cavity of the treatment cavity 5, there is a filtering component. On the upper layer of the filtering component, there is a sieve layer 4 with sieve holes. On the lower layer of the filtering component, there are multiple layers of filter layers 3 filled with activated carbon.

[0021] Introduce seawater into the separation tank 1 through the water inlet 2, use the sieve layer 4 to filter large particle impurities in the seawater, and use the filter layer 3 to absorb and treat suspended impurities in the seawater.

[0022] On the other side inner cavity of the separation tank 1, it is set as a heating cavity 6. The lower end of the treatment cavity 5 communicates with the upper end of the heating cavity 6. At the lower end of the treatment cavity 5, there is a water pump 31. At the upper end of the heating cavity 6, there is a sprinkler head 11. The sprinkler head 11 is communicated with the water pump 31 through a connecting pipe 30. The lower end of the sprinkler head 11 faces the heating plate 15.

[0023] Transport the filtered seawater to the sprinkler head 11 through the water pump 31, and use the sprinkler head 11 to spray the seawater on the heating plate 15 to achieve the purpose of heating and vaporization.

[0024] There is a vertically arranged lifting cavity 12 between the heating cavity 6 and the treatment cavity 5. A screw rod 13 is vertically installed in the lifting cavity 12 in a threaded rotation manner. A screw hole 26 is provided at the upper end of the lifting cavity 12. The upper end of the screw rod 13 extends to the outside of the lifting cavity 12. An external thread 27 that is in threaded rotation cooperation with the screw hole 26 is provided on the screw rod 13.

[0025] By the threaded rotation of the screw rod 13 on the screw hole 26, the height adjustment of the screw rod 13 is realized.

[0026] Multiple groups of cross plates 18 are elastically sleeved on the screw rod 13 at intervals. Multiple groups of fixing rings 19 and supporting rings 22 are fixedly distributed on the outer wall of the screw rod 13 at intervals. The fixing rings 19 and the supporting rings 22 are respectively located at the upper and lower ends of the cross plate 18. A long circular groove 23 is vertically penetrated through the cross plate 18. The long circular groove 23 is sleeved on the outside of the screw rod 13. A first spring 20 is provided at the upper end of the long circular groove 23. The first spring 20 is pressed between the upper end face of the cross plate 18 and the fixing ring 19. The width of the long circular groove 23 is smaller than the outer diameters of the first spring 20, the supporting ring 22, and the fixing ring 19. The length of the long circular groove 23 is greater than the outer diameter of the screw rod 13.

[0027] The elastic installation of the cross plate 18 is realized through the first spring 20. When the screw rod 13 rises and falls in height, the cross plate 18 is driven to rotate by the supporting plate 22, so as to adjust the inclination angle of the heating plate 15 in the heating cavity 6, and then control the contact area between the seawater and the heating plate 15 by angle adjustment, realize the control of the vaporization speed, and facilitate the adaptation of the vaporization speed to other processes such as condensation and filtration.

[0028] Multiple groups of rotating seats 14 corresponding to the cross plates 18 are provided between the lifting cavity 12 and the heating cavity 6. A jack 29 sleeved on the rotating seat 14 is provided on the cross plate 18. The heating plate 15 is obliquely fixed at the end of the cross plate 18 extending to one side of the heating cavity 6. A heating resistance wire is arranged inside the heating plate 15. Multiple groups of through holes 28 distributed in a matrix are provided on the heating plate 15.

[0029] The rotating installation of the cross plate 18 is realized through the rotating seat 14. The contact area between the seawater and the heating plate 15 is increased by using the through holes 28, thereby improving the vaporization efficiency.

[0030] A heating plate 15 extending to the heating cavity 6 is provided on one side of the cross plate 18. A partition plate 9 is vertically arranged on the other side of the heating cavity 6. Multiple groups of through holes 10 linearly distributed are provided on the partition plate 9. An exhaust port 7 communicating with the inner cavity outside the partition plate 9 is provided on the side wall of the separation box 1.

[0031] The seawater is separated by the partition plate 9 to prevent the seawater from spraying onto the exhaust port 7 and causing the already vapor to come into contact with the seawater again, improving the purity of the seawater desalination treatment. At the same time, the generated vapor overflows along the through holes 10 and is discharged through the exhaust port 7.

[0032] A pull rope 25 is vertically and elastically arranged on the partition plate 9. A scraping plate 21 is slidably sleeved on the upper end surface of the heating plate 15. The front and rear side walls of the heating plate 15 are provided with sliding grooves 16. The two ends of the scraping plate 21 are slidably installed on the sliding grooves 16. The middle section of the scraping plate 21 fits the upper end surface of the heating plate 15. The sliding installation of the scraping plate 21 is realized through the sliding grooves 16.

[0033] The scraping plate 21 is connected to the pull rope 25 through a towing rope 17. The pull rope 25 is vertically lifted and installed along the partition plate 9. One end of the towing rope 17 is fixedly tied to the pull rope 25. One end of the pull rope 25 extends to the outside of the upper end of the separation box 1. A pull ring 8 is arranged at the end of the pull rope 25. A second spring 24 is sleeved on the pull rope 25. The second spring 24 is pressed between the outer wall of the upper end of the separation box 1 and the pull ring 8.

[0034] Through the cooperation of the pull rope 25 and the towing rope 17, the synchronous linkage of the rotation of the heating plate 15 and the sliding of the scraping plate 21 is realized.

[0035] Working principle: By the threaded rotation of the screw 13 on the screw hole 26, the height adjustment of the screw 13 is realized. When the screw 13 rises and falls in height, the supporting plate 22 is used to drive the cross plate 18 to rotate, so as to achieve the purpose of adjusting the inclination angle of the heating plate 15 in the heating cavity 6. Furthermore, by adjusting the angle, the contact area between the seawater and the heating plate 15 is controlled, and the vaporization speed is controlled, so as to facilitate the adaptation of the vaporization speed to other processes such as condensation and filtration.

[0036] During the downward movement of the screw 13, under the elastic force of the first spring 20, the cross plate 18 is driven to deflect downward, so that during the deflection process, the distance between the scraping plate 21 and the partition plate 9 increases. Furthermore, the towing rope 17 pulls the pull rope 25 downward, and the pull rope 25 presses down and the second spring 24 is compressed. During the upward movement of the screw 13, the heating plate 15 rotates upward. During the rotation process, the second spring 24 resets. Using the elastic force of the second spring 24, the scraping plate 21 slides on the heating plate 15 synchronously under the cooperation of the pull rope 25 and the towing rope 17. As the scraping plate 21 slides, the adhered impurities and water scale are scraped off to ensure the heating efficiency of the heating plate 15. When the angle of a single rotation process is small, the pull ring 8 can be pulled to realize the drive of the pull rope 25, so as to increase the sliding length of the scraping plate 21 and ensure the full scraping and cleaning of the heating plate 15.
