Description

Technical Field

[0001] This utility model belongs to the field of water purifier technology, specifically relating to a dual-tank forward osmosis water purifier. Background Technology

[0002] Forward osmosis refers to the process by which water spontaneously flows through a semi-permeable membrane from a region of high water chemical potential (or lower osmotic pressure) to a region of low water chemical potential (or higher osmotic pressure) under the influence of osmotic pressure. Compared with pressure-driven membrane separation water treatment technologies (such as ultrafiltration, nanofiltration, and reverse osmosis), forward osmosis has advantages such as low pressure, low energy consumption, and lower membrane fouling. Currently, existing forward osmosis technology is generally used in large-scale wastewater treatment or small portable water purification devices. Large devices are expensive and difficult to carry, while small water purification devices typically combine clean and dirty water tanks, resulting in limited storage capacity and complex structures. The manufacturing process is cumbersome, and cleaning and maintenance are difficult. Therefore, there is an urgent need for a dual-tank forward osmosis water purifier that can solve these problems. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a dual-tank forward osmosis water purifier that is easy to carry and convenient to maintain.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dual-tank forward osmosis water purifier includes a clean water tank and a dirty water tank. Both the clean water tank and the dirty water tank are tanks with an internal cavity and an opening at one corner of the upper end. A first end cap and a second end cap are screwed onto the openings of the clean water tank and the dirty water tank, respectively. The first end cap has a water inlet and a vent. The second end cap has a filling port and a water outlet, which are connected by a clean water pipe. A filter is installed on the second end cap and is arranged in the internal cavity of the dirty water tank. A syrup feeding tray is installed on the upper side of the dirty water tank. A syrup bag is located inside the syrup feeding tray, and the outlet pipe of the syrup bag is connected to the filling port.

[0006] Preferably, the filter includes a first partition, a forward osmosis membrane, a liquid extraction cylinder, a liquid extraction tank, a support chamber, and a second partition. The filter is internally supported by a rigid hollow support frame, with a cylindrical liquid extraction cylinder centrally located. A hollow support chamber is formed between the liquid extraction cylinder and the support frame, and this support chamber is connected to an inlet pipe and an outlet pipe, which are respectively connected to a feed port and a water outlet. A liquid extraction tank is formed on one side of the liquid extraction cylinder, which is in close contact with the support frame. The support frame is externally wound with a filter membrane and a second partition wrapped together in an Archimedean spiral. The filter membrane consists of a forward osmosis membrane on two sides and a first partition in the middle. The liquid extraction cylinder communicates with the interior of the filter membrane, allowing the liquid extraction to flow into the middle of the two forward osmosis membranes, thereby creating an osmotic pressure difference with the water to be treated outside the membrane.

[0007] Preferably, the vent is fitted with a sealing cap.

[0008] Preferably, a retaining ring is installed at the upper end of the injection port, and a misalignment block is slidably installed on the inner side of the injection port at the bottom of the retaining ring via a spring. The outer side of the misalignment block penetrates the injection port, and through holes are provided inside both the retaining ring and the misalignment block. The water outlet pipe of the syrup bag is arranged between the two through holes.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the dual-tank forward osmosis water purifier combines a clean water tank and a dirty water tank, has low manufacturing cost, is easy to carry and take, and does not take up too much time for subsequent cleaning and maintenance. It has a good water purification effect and can remove impurities from the water; it fully meets the needs of ordinary families. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 3 As shown, a dual-tank forward osmosis water purifier includes a clean water tank 1 and a dirty water tank 10. Both the clean water tank 1 and the dirty water tank 10 are tanks with internal cavities and an opening at one corner of the upper end. The opening is located at the upper corner of the tank, allowing for convenient addition and pouring of the solution. A first end cap 4 and a second end cap 9 are screwed tightly onto the openings of the clean water tank 1 and the dirty water tank 10, respectively. The first end cap 4 has a water inlet 3 and a vent 5; the second end cap 9 has a filling port 7 and a water outlet 8. The outlet 8 and inlet 3 are connected by a clean water pipe 2. The inlet 3 and vent 5 are provided on the first end cap 4, and the filling port 7 and outlet 8 are provided on the second end cap 9. This makes it convenient for later maintenance and replacement, and the cost is low. A filter is installed on the second end cap 9. The filter is arranged in the internal cavity of the dirty water tank 10. A syrup feeding tray 6 is installed on the upper side of the dirty water tank 10. A syrup bag is provided inside the syrup feeding tray 6. The water outlet pipe of the syrup bag is connected to the filling port 7.

[0017] Specifically, the filter includes a first partition 11, a forward osmosis membrane 12, a liquid extraction cylinder 13, a liquid extraction tank 14, a support chamber 17, and a second partition 18. The filter is internally supported by a rigid hollow support frame. A cylindrical liquid extraction cylinder 13 is fitted at the center of the support frame, forming a hollow support chamber 17 between the liquid extraction cylinder 13 and the support frame. The liquid extraction cylinder 13 is connected to an inlet pipe 15 and an outlet pipe 16, which are respectively connected to a feed inlet 7 and a water outlet 8. A liquid extraction tank 14 is formed on one side of the liquid extraction cylinder 13, which is close to the support frame. The support frame is externally wound with a filter membrane and a second partition 18 arranged in an Archimedean spiral. The filter membrane consists of a layer of forward osmosis membrane 12 on each side, and a central... The filter membrane consists of a first partition 11; the entire filter membrane is quadrilateral, with three perimeters sealed and closed, leaving one side open. The two sides of the positive osmosis membrane (12) are tightly fitted to the absorbent tank (15), so that the absorbent cylinder 13 is connected to the inside of the filter membrane, allowing the absorbent to flow into the middle of the two positive osmosis membranes 12, thereby forming an osmotic pressure difference with the water to be treated outside the membrane. The first partition 11 separates the two positive osmosis membranes 12 to prevent the positive osmosis membranes 12 from sticking together, so that the purified water molecules cannot flow in the filter membrane and thus cannot flow out through the absorbent tank 14 to the absorbent bucket; the second partition 18 separates the filter membranes to prevent the filter membranes from sticking together, so that the wastewater molecules cannot flow outside the filter membrane and thus cannot be filtered through the membrane.

[0018] Specifically, the vent 5 is equipped with a sealing cover, and the system will not work when the vent 5 is closed.

[0019] Specifically, a retaining ring 73 is installed at the upper end of the injection port 7. A misalignment block 72 is slidably installed on the inner side of the injection port 7 at the bottom of the retaining ring 73 via a spring 71. The outer side of the misalignment block 72 penetrates the injection port 7. Both the retaining ring 73 and the misalignment block 72 have through holes 74. The water outlet tube of the syrup bag is arranged between the two through holes 74. After pressing down the misalignment block 72 on the injection port 7 to align the through holes 74 on the retaining ring 73 and the misalignment block 72, the water outlet tube on the syrup bag is inserted into the injection port 7. After releasing, the misalignment block 72 and the retaining ring 73 can clamp the water outlet tube on the syrup bag to prevent it from falling off.

[0020] In use, remove the second end cap 9 and filter from the dirty water bucket 10, drain the water from the dirty water bucket 10, then inject the water to be filtered, tighten the second end cap 9, connect the inlet 3 and outlet 8 through the clean water pipe 2, place the syrup bag into the syrup feeding tray 6, press down the misalignment block 72 on the filling port 7, align the through hole 74 on the clamping ring 73 with the through hole 74 on the misalignment block 72, insert the water outlet pipe on the syrup bag into the filling port 7, and after releasing, the misalignment block 72 and the clamping ring 73 can clamp the water outlet on the syrup bag. To prevent it from falling off, after installation, the liquid in the syrup bag enters the extractor cylinder 13 through the inlet pipe 15. The syrup in the extractor cylinder 13 flows into the filter membrane through the extractor tank 14, forming an osmotic pressure difference with the water to be treated outside the filter membrane, causing the water molecules of the water to be treated to mix with the syrup. As more and more external water enters, the concentration of the extractor also decreases. When the extractor accumulates to a certain volume, it will be transported to the clean water tank 1 through the outlet pipe 16 at the end of the extractor cylinder 13.

[0021] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
