TECHNICAL FIELD
[0001] The application relates to the technical field of seawater desalination, in particular to a mixed seawater desalination device. BACKGROUND
[0002] Seawater desalination is to produce fresh water by desalting seawater. It is an open-source incremental technology for water resource utilization, can increase the total amount of fresh water, and is not affected by time and space and climate, and can guarantee stable water supply for coastal residents drinking water and industrial boiler water supply. The process of obtaining fresh water from seawater is called seawater desalination. The seawater desalination methods used at present are seawater freezing method, electrodialysis method, distillation method, reverse osmosis method, and ammonium carbonate ion exchange method. At present, the reverse osmosis membrane method and the distillation method are the mainstream in the market.
[0003] The existing seawater desalination device generally heats seawater to boiling, then passes water vapor through a condenser, condenses water vapor into water droplets through the condenser, and then collects the condensed water droplets, thereby completing the desalination of seawater. However, in the process of use, since there are a large amount of salt and impurities in seawater, when seawater boils to form water vapor, the residual salt and impurities in seawater will adhere to the inner wall of the heating mechanism. If it is not cleaned for a long time, the heat conduction effect of the heating mechanism will be reduced, thereby affecting the desalination efficiency of seawater, which is inconvenient for users to use. CONTENT OF THE UTILITY MODEL
[0004] The application provides a mixed seawater desalination device to solve the problem that the existing seawater desalination device generally heats seawater to boiling, then passes water vapor through a condenser, condenses water vapor into water droplets through the condenser, and then collects the condensed water droplets, thereby completing the desalination of seawater. However, in the process of use, since there are a large amount of salt and impurities in seawater, when seawater boils to form water vapor, the residual salt and impurities in seawater will adhere to the inner wall of the heating mechanism. If it is not cleaned for a long time, the heat conduction effect of the heating mechanism will be reduced, thereby affecting the desalination efficiency of seawater, which is inconvenient for users to use.
[0005] The application provides a mixed seawater desalination device, which comprises a mounting bottom plate, a heating box is mounted at the top end of the mounting bottom plate, a gas pump is mounted at one end of the heating box, an air suction pipe is mounted at one end of the gas pump, an exhaust pipe is mounted at the end of the gas pump away from the air suction pipe, a condenser is connected to one end of the exhaust pipe, a drain pipe is connected to one end of the condenser, a driving hydraulic cylinder is mounted at the top end of the heating box, a hydraulic cylinder driving shaft is mounted at the bottom end of the driving hydraulic cylinder, a mounting bracket is fixed at the bottom end of the hydraulic cylinder driving shaft, a driving electric cylinder is also mounted at one end of the heating box, and a push plate is mounted at one end of the driving electric cylinder.
[0006] Preferably, the heating box is provided with a water inlet pipe at one end.
[0007] Preferably, the bottom of the heating box is provided with a mounting groove, and a heating component is installed inside the mounting groove.
[0008] Preferably, an air extraction head is connected to the top end of the air extraction pipe.

[0011] Preferably, a cleaning box is provided at one end of the heating box, and a cleaning groove is provided at one end of both the heating box and the cleaning box. A collection chamber is installed inside the cleaning box, and handles are installed at both ends of the collection chamber.
[0012] Beneficial effects:
[0013] Existing seawater desalination equipment typically heats seawater to boiling, then condenses the steam into water droplets in a condenser, which is then collected to complete the desalination process. However, during operation, due to the large amount of salt and impurities in seawater, after the seawater boils and forms steam, the residual salt and impurities adhere to the inner wall of the heating mechanism. If this is not cleaned over a long period, the heat conduction of the heating mechanism will decrease, thus affecting the desalination efficiency.
[0014] When using a heating tank for long-term seawater desalination, a large amount of impurities and salt particles from the seawater can easily remain on the inner wall of the tank. Failure to clean this for a long time will reduce the heating efficiency of the tank and affect the desalination efficiency. To address this, the hydraulic cylinder can be activated, causing the drive shaft to move the mounting bracket and side wall scraper downwards. The scraper moves along the inner wall of the heating tank, scraping off the salt particles and impurities that adhere to it and causing them to fall to the bottom of the tank. Then, by activating the electric cylinder, a pusher plate moves along the bottom of the tank, pushing the salt particles and impurities into a cleaning trough. From there, they fall into a collection chamber inside the cleaning tank. When cleaning is needed, the collection chamber can be pulled out of the cleaning tank by pulling the handle, thus completing the cleaning operation.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0033] This utility model provides, for example Figures 1-8 The hybrid seawater desalination device shown includes a mounting base plate 1, a heating box 2 mounted on the top of the mounting base plate 1, an air pump 6 mounted on one end of the heating box 2, an air extraction pipe 8 mounted on one end of the air pump 6, an exhaust pipe 9 mounted on the end of the air pump 6 away from the air extraction pipe 8, a condenser 10 connected to one end of the exhaust pipe 9, a drain pipe 11 connected to one end of the condenser 10, a driving hydraulic cylinder 13 mounted on the top of the heating box 2, a hydraulic cylinder drive shaft 14 mounted on the bottom of the driving hydraulic cylinder 13, a mounting bracket 15 fixed to the bottom of the hydraulic cylinder drive shaft 14, and a driving electric cylinder 17 mounted on one end of the heating box 2, with a push plate 18 mounted on one end of the driving electric cylinder 17.
[0034] In this system, by connecting the seawater outlet to the inlet pipe 3, seawater can be introduced into the heating tank 2 through the inlet pipe 3 when desalination is required. Then, by opening the heating component 5 in the mounting slot 4 at the bottom of the heating tank 2, the seawater inside the heating tank 2 is heated. When the seawater reaches boiling point, the air pump 6 is turned on, causing the air extraction pipe 8 and the air extraction head 7 to extract the water vapor from the heating tank 2 into the exhaust pipe 9. The vapor is then condensed into water droplets by the condenser 10, and subsequently discharged into the water tank 12 through the drain pipe 11. During prolonged seawater desalination using the heating tank 2, a large amount of impurities and salt particles from the seawater can easily remain on the inner wall of the heating tank 2. Failure to clean this residue over a long period can lead to… The reduced heating efficiency inside the heating box 2 affects the seawater desalination efficiency. At this time, the hydraulic cylinder 13 can be opened, causing the hydraulic cylinder drive shaft 14 to drive the mounting bracket 15 and the side wall scraper 16 to move downwards. The side wall scraper 16 moves downwards along the inner wall of the heating box 2, thereby scraping off the salt particles and impurities attached to the inner wall of the heating box 2 and causing them to fall to the bottom of the heating box 2. Then, by opening the electric cylinder 17, the push plate 18 pushes the salt particles and impurities at the bottom of the heating box 2 to the impurity removal tank 19. After that, they fall into the collection chamber 21 inside the cleaning box 20 through the impurity removal tank 19. When cleaning is required, the collection chamber 21 can be pulled out of the cleaning box 20 by pulling the handle 22, thereby completing the cleaning operation.
[0035] One end of the heating box 2 is equipped with a water inlet pipe 3.
[0036] By connecting the seawater outlet to the inlet pipe 3, when seawater desalination is required, seawater can be introduced into the interior of the heating tank 2 through the inlet pipe 3.
[0037] The bottom of the heating box 2 is provided with a mounting groove 4, and the heating component 5 is installed inside the mounting groove 4.
[0038] Specifically, the heating component 5 in the mounting slot 4 at the bottom of the heating box 2 is opened, and the seawater inside the heating box 2 is heated by the heating component 5.
[0039] The top end of the suction pipe 8 is connected to the suction head 7.
[0040] When the seawater is heated to boiling point by the heating box 2, the air pump 6 is turned on, so that the air extraction pipe 8 and the air extraction head 7 extract the water vapor in the heating box 2 to the exhaust pipe 9, and then condense it into water droplets through the condenser 10.
[0041] The bottom end of the drain pipe 11 is connected to a water tank 12.
[0042] The condensed water is discharged into the water tank 12 through the drain pipe 11 for collection.
[0043] The bottom of the mounting bracket 15 is connected to a side wall scraper 16.
[0044] Specifically, by opening the drive hydraulic cylinder 13, the hydraulic cylinder drive shaft 14 drives the mounting bracket 15 and the side wall scraper 16 to move downward. The side wall scraper 16 moves downward along the inner wall of the heating box 2, thereby scraping off the salt particles and impurities attached to the inner wall of the heating box 2 and causing them to fall to the bottom of the heating box 2.
[0045] A cleaning box 20 is provided at one end of the heating box 2. Both the heating box 2 and the cleaning box 20 have a cleaning groove 19 at one end. A collection chamber 21 is installed inside the cleaning box 20. Both ends of the collection chamber 21 are equipped with handles 22.
[0046] Among them, by opening a removal tank 19 at one end of the heating box 2 and the cleaning box 20, it is convenient for users to collect and treat the salt particles and impurities inside the heating box 2.
[0047] Working principle: When using this hybrid seawater desalination device, the seawater outlet is connected to the inlet pipe 3. When seawater needs to be desalinated, the seawater can be introduced into the heating tank 2 through the inlet pipe 3. Then, the heating component 5 in the mounting slot 4 at the bottom of the heating tank 2 is opened to heat the seawater inside the heating tank 2. When the seawater is heated to boiling, the air pump 6 is turned on, so that the air extraction pipe 8 and the air extraction head 7 extract the water vapor in the heating tank 2 to the exhaust pipe 9. Then, the water vapor is condensed into water droplets by the condenser 10, and then discharged into the water tank 12 for collection through the drain pipe 11.
[0048] When using the heating box 2 for long-term seawater desalination, a large amount of impurities and salt particles from seawater can easily remain on the inner wall of the heating box 2. If not cleaned for a long time, the heating efficiency inside the heating box 2 will decrease, affecting the seawater desalination efficiency. At this time, the hydraulic cylinder 13 can be opened, so that the hydraulic cylinder drive shaft 14 drives the mounting bracket 15 and the side wall scraper 16 to move downward. The side wall scraper 16 moves downward along the inner wall of the heating box 2, thereby scraping off the salt particles and impurities attached to the inner wall of the heating box 2 and letting them fall to the bottom of the heating box 2. Then, by opening the electric cylinder 17, the push plate 18 pushes the salt particles and impurities at the bottom of the heating box 2 to the impurity removal tank 19 along the bottom of the heating box 2. Then, they will fall into the collection chamber 21 inside the cleaning box 20 through the impurity removal tank 19. When cleaning is required, the collection chamber 21 can be pulled out of the cleaning box 20 by pulling the handle 22, thereby completing the cleaning operation.
[0049] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
