Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of seawater desalination devices, and in particular to a portable membrane-coated seawater desalination device. Background Technology
[0002] Seawater desalination is a technology that removes salt and other impurities from seawater to obtain fresh water. Current seawater desalination generally utilizes reverse osmosis membrane separation technology. By applying a pressure greater than the osmotic pressure to the seawater, water in the seawater passes through the reverse osmosis membrane, while salt and other impurities are blocked outside. However, existing seawater desalination devices are generally large and difficult to carry, thus requiring a new type of seawater desalination device to solve this problem. Utility Model Content
[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.
[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a portable membrane-coated seawater desalination device.
[0005] To achieve the above objectives, the technical solution of this utility model is: a portable membrane-coated seawater desalination device, comprising a reverse osmosis membrane assembly, a mounting plate fixedly connected to the reverse osmosis membrane assembly, a water receiving box rotatably connected to the mounting plate, a pumping mechanism and a pressurizing mechanism fixedly connected to the mounting plate, the pumping mechanism and the pressurizing mechanism being interconnected through a filtration mechanism, the pumping mechanism being connected to a pumping pipe, the pressurizing mechanism being connected to the inlet of the reverse osmosis membrane assembly through an outlet pipe, the outlet of the reverse osmosis membrane being aligned with the top of the water receiving box, the mounting plate being provided with a power mechanism for driving the pumping mechanism and the pressurizing mechanism, and a support mechanism for fixing the mounting plate being provided between the water receiving box and the mounting plate.
[0006] By adopting the above technical solution, the power mechanism drives the pumping mechanism and the pressurizing mechanism to operate. The pumping mechanism draws seawater through the pumping pipe into the filtration mechanism for preliminary filtration. Then, the pressurizing mechanism forces the seawater from the filtration mechanism into the reverse osmosis membrane module at a certain pressure for desalination. Finally, the desalinated water is discharged from the reverse osmosis membrane module and collected through a water collection box, thus achieving seawater desalination. The pumping mechanism, pressurizing mechanism, filtration mechanism, and reverse osmosis membrane module are all mounted on a mounting plate. The mounting plate can be flipped to place these mechanisms into the water collection box, making the entire seawater desalination device easy to carry and transport. A support mechanism supports the mounting plate, allowing it to remain in its extended state.
[0007] Preferably, the pumping mechanism includes a pumping cylinder, a pumping rod, and a pumping plate. The pumping cylinder is fixedly connected to the mounting plate, and the pumping plate is slidably connected inside the pumping cylinder. A pumping chamber is formed between the pumping plate and the bottom of the pumping cylinder. The pumping pipe is connected to the pumping chamber through a one-way valve, and the filtration mechanism is connected to the pumping chamber through a two-way valve. The pumping rod is fixedly connected to the pumping plate and is driven by the power mechanism. This invention uses a power mechanism to drive the pumping rod to reciprocate, causing the pumping plate to slide back and forth inside the pumping cylinder. When the pumping plate slides to the left, a negative pressure is created in the pumping chamber. At this time, one-way valve one is open, and one-way valve two is closed, allowing seawater to be pumped into the pumping chamber through the pumping pipe. When the pumping plate slides to the right, one-way valve one is closed, and one-way valve two is open, allowing seawater to enter the filtration mechanism. This process repeats continuously, achieving the function of continuously pumping seawater into the filtration mechanism.
[0008] Preferably, the pressurizing mechanism includes a pressurizing cylinder, a pressurizing plate, and a pressurizing rod. The pressurizing cylinder is fixedly connected to the mounting plate, and the pressurizing plate is slidably connected inside the pressurizing cylinder. A pressurizing chamber is formed between the pressurizing plate and the bottom of the pressurizing cylinder. The outlet pipe is connected to the pressurizing chamber via a one-way valve three, and the filtration mechanism is connected to the pressurizing chamber via a one-way valve four. The pressurizing rod is fixedly connected to the pressurizing plate and is driven by the power mechanism. This invention uses a power mechanism to drive the pressurizing rod to reciprocate, causing the pressurizing plate to slide reciprocally inside the pressurizing cylinder. When the pressurizing plate slides to the left, a negative pressure is created in the pressurizing chamber. At this time, one-way valve three is open, and one-way valve four is closed, allowing seawater to be drawn from the filtration mechanism into the pressurizing chamber. When the pressurizing plate slides to the right, one-way valve three is closed, and one-way valve four is open, allowing seawater to enter the reverse osmosis membrane module. This process is repeated to continuously draw seawater into the reverse osmosis membrane module.
[0009] Preferably, the pumping rod and the booster rod are connected as a single unit via a transmission frame, and both the pumping rod and the booster rod are fixedly connected to the transmission frame. This invention enables the pumping rod and the booster rod to be driven simultaneously by a single power source.
[0010] Preferably, the power mechanism includes a turntable and a transmission rod. The turntable is rotatably connected to the mounting plate, one end of the transmission rod is rotatably connected to an off-center point on the turntable, and the other end of the transmission rod is rotatably connected to the transmission frame. This invention utilizes the rotation of the turntable to drive one end of the transmission rod to continuously move closer to or away from the transmission frame, thereby causing the transmission frame to reciprocate. The turntable can be rotated manually or by a motor using chain or belt drive.
[0011] Preferably, the filtration mechanism includes a water storage box and a filter plate. The water storage box is fixedly connected to the mounting plate, and the filter plate is fixedly connected inside the water storage box, located in the middle of the water storage box. A connecting pipe is fixedly connected to the top of the water storage box, communicating with the inside of the water storage box, and the connecting pipe is connected to the one-way valve. A connecting pipe is fixedly connected to the bottom of the water storage box, communicating with the inside of the water storage box, and the connecting pipe is connected to the one-way valve. This utility model utilizes the water storage box to collect the filtered seawater, which is then extracted by the pressurization mechanism. The seawater pressurized from the pumping mechanism is collected by the filter plate and flows to the bottom of the water storage box through the mesh on the filter plate, while larger particles remain on the filter plate, thus achieving filtration.
[0012] Preferably, the support mechanism includes two support rods, which are respectively disposed on both sides of the water receiving box. Both ends of the two support rods are detachably connected to the mounting plate and the water receiving box via two sets of connecting mechanisms. This invention utilizes two support rods diagonally braced on both sides of the mounting plate, thereby ensuring that the mounting plate remains vertical.
[0013] Preferably, the connecting mechanism includes studs and fixing nuts. The studs are fixedly connected to the water receiving box or the mounting plate. Both ends of the support rod have insertion holes for the studs, and the fixing nuts are threadedly connected to the studs. In this invention, when fixing the mounting plate, the studs on the mounting plate and the water receiving box are simultaneously inserted into the insertion holes at both ends of the support rod. The threaded connection between the fixing nuts and the studs limits the position of the support rod, thereby supporting the mounting plate.
[0014] Preferably, a filter is provided at the end of the water pumping pipe. This invention utilizes the filter at the end of the water pumping pipe to pre-filter larger impurities, thereby improving filtration efficiency.
[0015] In summary, the beneficial effects of this utility model are:
[0016] 1. By using a mounting plate that can be rotatably connected to the water inlet box, all components can be flipped over and stored inside the water inlet box, making the desalination device easy to carry.
[0017] 2. The pumping mechanism and the booster mechanism are driven by a power mechanism, which enables mechanical driving and solves the problem of not being able to use electric drive.

The reverse osmosis membrane module 1 is fixedly connected to an mounting plate 2. The mounting plate 2 is rotatably connected to a water receiving box 3. The mounting plate 2 is fixedly connected to a pumping mechanism and a pressurizing mechanism. The pumping mechanism and the pressurizing mechanism are interconnected through a filtration mechanism. The pumping mechanism is connected to a pumping pipe 4. The pressurizing mechanism is connected to the inlet of the reverse osmosis membrane module 1 through an outlet pipe 5. The outlet of the reverse osmosis membrane is aligned with the top of the water receiving box 3. The mounting plate 2 is provided with a power mechanism for driving the pumping mechanism and the pressurizing mechanism. A support mechanism for fixing the mounting plate 2 is provided between the water receiving box 3 and the mounting plate 2.
[0033] By adopting the above technical solution, the power mechanism drives the pumping mechanism and the pressurizing mechanism to operate. The pumping mechanism draws seawater through the pumping pipe 4 into the filtration mechanism for preliminary filtration. Then, the pressurizing mechanism forces the seawater from the filtration mechanism into the reverse osmosis membrane module 1 at a certain pressure for desalination. Finally, the desalinated water is discharged from the reverse osmosis membrane module 1 and collected through the water receiving box 3, thus achieving seawater desalination. The pumping mechanism, pressurizing mechanism, filtration mechanism, and reverse osmosis membrane module 1 are all mounted on the mounting plate 2. The mounting plate 2 can be flipped to place the above mechanisms into the water receiving box 3, making the entire seawater desalination device easy to carry and transport. The support mechanism supports the mounting plate 2, allowing it to remain in an extended state.

The water pumping rod 7 is fixedly connected to the water pumping plate 8 and is connected to the power mechanism for transmission. The power mechanism drives the pumping rod 7 to reciprocate, which causes the pumping plate 8 to slide back and forth in the pumping cylinder 6. When the pumping plate 8 slides to the left, a negative pressure is formed in the pumping chamber 9. At this time, the one-way valve 10 is open and the one-way valve 2 is closed, and seawater is drawn into the pumping chamber 9 through the pumping pipe 4. When the pumping plate 8 slides to the right, the one-way valve 10 is closed and the one-way valve 2 is open, and seawater enters the filtration mechanism. This process is repeated to achieve the function of continuously drawing seawater into the filtration mechanism.
[0035] The pressurization mechanism includes a pressurization cylinder 12, a pressurization plate 13, and a pressurization rod 14. The pressurization cylinder 12 is fixedly connected to the mounting plate 2. The pressurization plate 13 is slidably connected inside the pressurization cylinder 12. A pressurization chamber 15 is formed between the pressurization plate 13 and the bottom of the pressurization cylinder 12. The water outlet pipe 5 is connected to the pressurization chamber 15 through a one-way valve 3 16. The filtration mechanism is connected to the pressurization chamber 15 through a one-way valve 4 17. The pressurization rod 14 is fixedly connected to the pressurization plate 13 and is connected to the power mechanism for transmission. The power mechanism drives the booster rod 14 to reciprocate, which causes the booster plate 13 to slide back and forth in the booster cylinder 12. When the booster plate 13 slides to the left, a negative pressure is formed in the booster chamber 15. At this time, the one-way valve 3 16 is open and the one-way valve 4 17 is closed, and seawater is drawn from the filtration mechanism into the booster chamber 15. When the booster plate 13 slides to the right, the one-way valve 3 16 is closed and the one-way valve 4 17 is open, and seawater enters the reverse osmosis membrane module 1. This process is repeated to achieve the function of continuously drawing seawater into the reverse osmosis membrane module 1.
[0036] The pump rod 7 and the booster rod 14 are connected as a whole by a transmission frame 18, and both the pump rod 7 and the booster rod 14 are fixedly connected to the transmission frame 18.

The turntable 19 can be rotated manually or by a motor using chain or belt drive.

The connecting pipe 24 is connected to a one-way valve 17. The water storage box 21 can collect the filtered seawater, which is then extracted by the pressurization mechanism. The seawater pressurized from the pumping mechanism is collected by the filter plate 22 and flows to the bottom of the water storage box 21 through the mesh on the filter plate 22, while larger particles remain on the filter plate 22, thus achieving filtration.
[0039] The support mechanism includes two support rods, which are respectively located on both sides of the water receiving box 3. Both ends of the two support rods are detachably connected to the mounting plate 2 and the water receiving box 3 via two sets of connecting mechanisms.
