Description

Technical Field

[0001] This invention belongs to the field of seawater desalination equipment, specifically relating to a small, low-consumption seawater desalination device for marine use. Background Technology

[0002] During ocean voyages, fresh water supply is a critical piece of equipment to ensure the survival of the crew and the normal operation of the ship. Marine desalination equipment needs to draw seawater from the bottom of the ship and pre-treat it before it enters the desalination unit.

[0003] During the pretreatment process, the existing dosing methods mostly involve continuously injecting chemicals through an injection port on the inlet pipe. The chemicals are naturally mixed with the seawater flow, resulting in poor mixing uniformity. If the seawater is not mixed evenly with chemicals, it will affect the desalination process. At the same time, adding too much chemicals may lead to waste. Adding additional stirring devices will affect the limited space on the ship, which will also affect the small boat with its limited space. Summary of the Invention

[0004] Therefore, it is necessary to provide a small, low-consumption marine desalination device to address the shortcomings of existing technologies and solve the seawater desalination problem.

[0005] To solve the above problems, this application adopts the following technical solution:

[0006] One objective of this application is to provide a small, low-consumption marine seawater desalination device comprising: a frame, an inlet engine fixedly mounted on the inner wall of the frame, an inlet pipe fixedly mounted on the inlet end of the inlet engine, a bracket fixedly mounted on the top of the inlet pipe, a mixer fixedly mounted on the top of the bracket, a drive shaft fixedly mounted on the bottom of the mixer, a fixing plate fixedly mounted on the inner wall of the inlet pipe, a filter screen fixedly mounted on the bottom of the fixing plate, a scraper fixedly mounted on the circumferential surface of the drive shaft, and a medicine inlet pipe fixedly mounted on the surface of the inlet pipe, the top of the medicine inlet pipe being fixedly connected to the surface of the medicine tank.

[0007] In some embodiments, a rotating plate is fixedly mounted on the circumferential surface of the drive shaft, a lower base plate is fixedly mounted on the circumferential surface of the drive shaft, and a medicine inlet hole is provided on the surface of the water inlet pipe.

[0008] In some embodiments, the inlet hole is located on the rotational trajectory of the bottom plate, the rotating plate is located above the fixed plate, and can scrape off seaweed and other debris attached to the filter screen during rotation. The scraper is located below the filter screen, and the blades of the scraper are arranged in a left-hand spiral. The left-hand spiral scraper blades can push the debris from the inside to the outside during rotation.

[0009] In some embodiments, a stirring shell is fixedly installed on the surface of the water inlet pipe, an outer stirring plate is fixedly installed on the circumferential surface of the scraper, the outer stirring plate is located between the surface of the water inlet pipe and the inner wall of the stirring shell, and a discharge hole is opened through the surface of the stirring shell.

[0010] In some embodiments, a crossbar is fixedly installed at one end of the inner wall of the water inlet pipe, and a scraper housing is fixedly installed at the other end of the crossbar. A scraper frame is slidably connected to the inner wall of the scraper housing, a scraper is fixedly installed on the surface of the scraper frame, and a protrusion is fixedly installed at the bottom of the scraper.

[0011] In some embodiments, the outer stirring plate is arranged in a left-handed spiral, and the left-handed blades of the outer stirring plate can push the debris from the inside to the outside. A small spring is provided between the scraper holder and the scraper housing. The scraper holder is located on the movement trajectory of the protrusions. Multiple protrusions are fixedly installed on the bottom of the scraper, and the multiple protrusions can continuously push the scraper holder.

[0012] In some embodiments, a push tube is fixedly mounted on the surface of the stirring shell, a push tube housing is fixedly mounted on the surface of the push tube, a slide rail is fixedly mounted on the inner wall of the push tube housing, an inclined block is fixedly mounted on the bottom of the inner wall of the push tube housing, a push plate is slidably connected to the inner wall of the push tube housing, a round push block is fixedly mounted on the back of the push plate, a baffle plate is fixedly mounted on the top of the push plate, a connecting rod is fixedly mounted on the surface of the baffle plate, a horizontal push frame is slidably connected to the inner wall of the push tube housing, a vertical plate is fixedly mounted on the surface of the horizontal push frame, a round plate is rotatably connected to the surface of the vertical plate, and a triangular plate is fixedly mounted on the front of the vertical plate.

[0013] In some embodiments, the horizontal pusher is located above the surface of the inclined block and the push plate, a large spring is provided between the push tube housing and the horizontal pusher, and a medium spring is provided between the round pusher block and the inner wall of the push tube housing.

[0014] 1. This invention, through the cooperation of a rotating plate and a lower base plate, allows for intermittent drug administration by intermittently blocking the drug inlet hole with the rotating lower base plate. When the lower base plate blocks the drug inlet hole, the rotating plate also rotates to the remaining gap position of the fixed plate, blocking most of the gap. This allows the water intake engine to only draw in a small amount of seawater, while the remaining seawater and medicine mix in the water pipe. With the continuous rotation and stirring of the scraper, the seawater and medicine are further thoroughly mixed. This allows for intermittent drug administration and continuous stirring, saving space, improving the mixing of the medicine, and reducing the waste of medicine.

[0015] 2. This invention utilizes a scraper with continuously rotating counterclockwise blades to remove seaweed, debris, and other impurities from the filter screen surface during rotation. These impurities are then pushed into the mixing shell by the counterclockwise rotating blades and, similarly, by the outer stirring plate of the counterclockwise rotating blades. The outer stirring plate, rotating along the inner wall of the scraper, pushes the scraper into the push tube, ensuring the cleanliness of the pipe. Simultaneously, the protrusion at the bottom of the scraper rotates with the drive shaft, squeezing the scraper frame during rotation. This squeezing causes the scraper to cut the circumference of the drive shaft, chopping up any tangled seaweed and preventing it from jamming the drive shaft, thus ensuring its continuous operation.

[0016] 3. This invention uses the continuous rotation of the outer stirring plate to drive the circular pusher block to move back and forth continuously. This continuous movement drives the outer stirring plate to move forward continuously, which can push out the debris at the bottom of the outer stirring plate from the push tube. The debris can then be moved back to the initial position along the slide rail to push new debris again. During the return process, the circular plate and the vertical plate form a one-way opening structure, which can maintain the maximum area for pushing during the push process and return in an open state during the return process, which can reduce the debris brought back and reduce resistance, thereby improving the efficiency of pushing debris.

[0031] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0032] like Figure 1 - Figure 12 As shown, the present invention provides a small, low-consumption marine desalination device comprising: a frame 1; an inlet engine 2 fixedly mounted on the inner wall of the frame 1; an inlet pipe 3 fixedly mounted on the inlet end of the inlet engine 2; a bracket 411 fixedly mounted on the top of the inlet pipe 3; a mixer 4 fixedly mounted on the top of the bracket 411; a drive shaft 401 fixedly mounted on the bottom of the mixer 4; a fixing plate 403 fixedly mounted on the inner wall of the inlet pipe 3; a filter screen 407 fixedly mounted on the bottom of the fixing plate 403; a scraper 404 fixedly mounted on the circumferential surface of the drive shaft 401; and a medicine inlet pipe 406 fixedly mounted on the surface of the inlet pipe 3. The top of the medicine inlet pipe 406 is fixedly connected to the surface of the medicine tank 410. Most of the remaining seawater and medicine are mixed in the water pipe. With the continuous rotation and stirring of the scraper 404, the seawater and medicine can be further thoroughly mixed.

[0033] A rotating plate 402 is fixedly installed on the circumferential surface of the drive shaft 401, and a lower base plate 405 is fixedly installed on the circumferential surface of the drive shaft 401. A drug inlet hole is opened on the surface of the water inlet pipe 3. This allows for intermittent drug administration and continuous stirring, which can save space, improve the mixing of drugs, and reduce the waste of drug solution.

[0034] The medicine inlet is located on the rotation trajectory of the bottom plate 405. The rotating plate 402 is located above the fixed plate 403 and can scrape off seaweed and other debris attached to the surface of the filter screen 407 during rotation. The scraper 404 is located below the filter screen 407. The blades of the scraper 404 are arranged in a left-hand spiral. The left-hand spiral blades of the scraper 404 can push the debris from the inside to the outside during rotation.

[0035] A stirring shell 408 is fixedly installed on the surface of the water inlet pipe 3, and an outer stirring plate 409 is fixedly installed on the circumferential surface of the scraper 404. The outer stirring plate 409 is located between the surface of the water inlet pipe 3 and the inner wall of the stirring shell 408. A discharge hole is opened through the surface of the stirring shell 408. It is also driven by the left-hand rotating blade of the outer stirring plate 409, and pushed into the push pipe 6 by the outer stirring plate 409 rotating with its inner wall. This can ensure that the inside of the pipe is clean.

[0036] A crossbar 5 is fixedly installed at one end of the inner wall of the water inlet pipe 3, and a scraper housing 501 is fixedly installed at the other end of the crossbar 5. A scraper holder 503 is slidably connected to the inner wall of the scraper housing 501. A scraper 504 is fixedly installed on the surface of the scraper holder 503. A protrusion 502 is fixedly installed at the bottom of the scraper 404. During the rotation, the scraper holder 503 is squeezed. The squeezed scraper holder 503 drives the scraper 504 to cut up and down on the circumference of the drive shaft 401, which can chop up the tangled seaweed.

[0037] The outer stirring plate 409 is arranged in a left-hand spiral. The left-hand spiral blades of the outer stirring plate 409 can push the debris from the inside to the outside. A small spring is provided between the scraper holder 503 and the scraper housing 501. The scraper holder 503 is located on the movement trajectory of the protrusion 502. Multiple protrusions 502 are fixedly installed at the bottom of the scraper 404. The multiple protrusions 502 can continuously push the scraper holder 503.

[0038] A push tube 6 is fixedly installed on the surface of the stirring shell 408. A push tube shell 601 is fixedly installed on the surface of the push tube 6. A slide rail 603 is fixedly installed on the inner wall of the push tube shell 601. An inclined block 602 is fixedly installed on the bottom of the inner wall of the push tube shell 601. A push plate 606 is slidably connected to the inner wall of the push tube shell 601. A round push block 607 is fixedly installed on the back of the push plate 606. A baffle plate 605 is fixedly installed on the top of the push plate 606. A connecting rod 604 is fixedly installed on the surface of the baffle plate 605. A horizontal push frame 608 is slidably connected to the inner wall of the push tube shell 601. A vertical plate 609 is fixedly installed on the surface of the horizontal push frame 608. A round plate 610 is rotatably connected to the surface of the vertical plate 609. A triangular plate 611 is fixedly installed on the front of the vertical plate 609. This allows debris at the bottom of the outer stirring plate 409 to be pushed out of the push tube 6, and it can move back to the initial position with the slide rail 603 to push new debris again.

[0039] The horizontal push frame 608 is located on the surface of the inclined block 602 and the push plate 606. A large spring is provided between the push tube housing 601 and the horizontal push frame 608. A medium spring is provided between the round push block 607 and the inner wall of the push tube housing 601. During the return process, a one-way opening structure is formed by the round plate 610 and the vertical plate 609, which can maintain the maximum area for pushing during the push process.

[0040] During operation: When the water intake engine 2 is turned on for water intake, the mixer 4 is started simultaneously. After the mixer 4 starts, it drives the rotating plate 402, scraper 404, and lower base plate 405 to rotate synchronously. Medicine is discharged into the water inlet pipe 3 through the medicine inlet hole. The rotation of the scraper 404 mixes the medicine. During the rotation of the lower base plate 405, it periodically blocks the medicine inlet hole, closing it during this process to achieve intermittent drug administration. When the lower base plate 405 blocks the medicine inlet hole, the rotating plate 402 rotates synchronously to the gap position of the fixed plate 403. The rotating plate 402 and the fixed plate 403 cooperate to widen the water inlet pipe 3. The system is partially closed while maintaining small gaps to allow continuous seawater flow. During the near-closed period, the seawater and medicine remain in the middle section of the inlet pipe 3. Then, the scraper 404 continuously rotates and stirs the medicine and seawater to mix them. As the bottom plate 405 rotates away from the inlet hole, the inlet hole reopens, and the medicine continues to flow into the inlet pipe 3. At the same time, the rotating plate 402 rotates away from the gap in the fixed plate 403, and the inlet pipe 3 resumes flow. The mixed medicine is then sucked in by the water intake engine 2, thus achieving the mixing of medicine while the seawater is being drawn in.

[0041] As the scraper 404 rotates, it scrapes off debris and seaweed adhering to the surface of the filter screen 407. The counter-clockwise rotating blades of the scraper 404 push the debris into the mixing housing 408. The rotation of the scraper 404 further drives the outer mixing plate 409 to rotate, and its counter-clockwise rotating blades similarly push the debris into the push tube 6. This pushes the debris away from the inner wall of the water inlet pipe 3, preventing the water inlet engine 2 from further sucking it in. Simultaneously... As the scraper 404 rotates, it drives the connected protrusion 502 to rotate as well. The rotation of the protrusion 502 presses against the scraper holder 503 on its movement trajectory. The scraper holder 503 is pushed up and down by the protrusion 502. The up and down movement of the scraper holder 503 will drive the connected scraper 504 to move up and down. The up and down movement of the scraper 504 will cut the circumference of the drive shaft 401, which can effectively chop up the tangled aquatic plants and prevent the aquatic plants from jamming the drive shaft 401 and affecting the mixer 4.

[0042] As the outer stirring plate 409 pushes the debris into the push tube 6, the rotation of the outer stirring plate 409 first contacts the circular push block 607. The circular push block 607, under pressure, will be squeezed inwards and move backwards. This movement of the circular push block 607 will cause the push plate 606 to move backwards. The movement of the push plate 606 will cause the horizontal push frame 608 to move backwards. The horizontal push frame 608 will move backwards along the inclined side of the inclined block 602. After moving backwards past the inclined side, the horizontal push frame 608 will be restricted by the right-angled side of the inclined block 602, and will not be subjected to the tension of the large spring. Returning, the outer stirring plate 409 continues to contact the circular push block 607, causing the horizontal push frame 608 to move backward until it touches the front end of the slide rail 603. The slide rail 603 is then compressed and lifted by the horizontal push frame 608. As the horizontal push frame 608 continues to move, it will pass the front end of the slide rail 603. Once past the slide rail 603, the horizontal push frame 608 will be restrained by the stop plate 605. Subsequently, the horizontal push frame 608 will move forward under the pull of a large spring. Continuing to move, the horizontal push frame 608 will slide onto the slide rail 603. After sliding onto the slide rail 603, the horizontal push frame 608 will be... The spring pulls forward until the horizontal pusher 608 slides to the rear end of the slide rail 603. The horizontal pusher 608 will fall into the gap at the rear end of the slide rail 603 and land on the surface of the push plate 606. The horizontal pusher 608 will then be pushed by the circular push block 607 to repeat the previous operation. This movement of the horizontal pusher 608 will push debris out of the push tube 6, preventing debris from being sucked back into the water inlet pipe 3 and contaminating the seawater, thus reducing the pressure on the filtration equipment. At the same time, during the process of the horizontal pusher 608 being pulled forward by the large spring, the circular plate 610 will not be subjected to... The vertical plate 609 opens due to obstruction, and the circular plate 610 is pushed forward and rotates to open by the seawater. This prevents the horizontal pusher 608 from pushing all the debris back into the mixing shell 408 during the retraction process. As the horizontal pusher 608 is pushed by the pusher plate 606, the blades of the circular plate 610 are larger than the vertical plate 609 and are restricted and blocked. The circular plate 610 is supported by the obstruction of the vertical plate 609. In this way, the circular plate 610 can push the debris with the largest possible area. Pushing the circular plate 610 with the largest possible area can push the debris out of the pusher tube 6 as much as possible.
