Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a purified water reverse osmosis filtration component. Background Technology

[0002] Reverse osmosis technology, as one of the most effective water purification methods, can effectively remove dissolved salts, organic matter, bacteria, viruses and other impurities from water through the selective permeability of semi-permeable membranes, resulting in high-quality purified water. Therefore, developing a reverse osmosis filtration component for purified water is particularly important.

[0003] A purified water reverse osmosis device, as described in reference announcement number CN221027850U, includes a reverse osmosis filter. The reverse osmosis filter includes a sludge discharge cylinder, with a water collection pipe fixed at its center. Reverse osmosis filter elements are threaded to both ends of the water collection pipe. Sleeves are fitted around the outer sides of the reverse osmosis filter elements. A purified water output pipe is embedded in the front of the sludge discharge cylinder, and its inner end is connected to the water collection pipe. A sludge collection hood is provided at the bottom of the sludge discharge cylinder. This device shortens the flow path by allowing water to enter from both ends of the reverse osmosis filter and discharging concentrated water from the middle of the filter. Furthermore, the collision of the two concentrated water streams within the drain pipe increases water pressure, enhancing the reverse osmosis filtration effect. Simultaneously, it creates turbulent flow, preventing the accumulation of impurities. The conical bottom of the sludge collection hood at the bottom of the drain pipe facilitates the collection of wastewater and impurities, enabling rapid discharge. As can be seen from the above, while this device can be effectively applied, it typically lacks multiple pretreatment modules at the front end of the components, making it difficult to remove large particulate impurities, residual chlorine, organic matter, etc., placing a heavy burden on the reverse osmosis components and consequently affecting their lifespan, a problem that frequently arises. Utility Model Content

[0004] The purpose of this invention is to provide a purified water reverse osmosis filtration component to solve the problem that although the device proposed in the background art can be applied well, it usually does not have multiple pretreatment modules at the front end of the component, making it difficult to remove large particulate impurities, residual chlorine, organic matter, etc. in the water, which makes the reverse osmosis component bear a heavy burden and thus affects the service life of the reverse osmosis component.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a purified water reverse osmosis filtration assembly, including a base frame, a support frame on one side of the top of the base frame, a control box mounted on the outer surface of the front of the base frame, a pretreatment tank on the top of the base frame on one side of the support frame, a first reverse osmosis treatment tank on the top of the base frame on one side of the pretreatment tank, a first flange connection on one side of the outer wall of the first reverse osmosis treatment tank, a second flange connection on the outer wall of the other side of the first reverse osmosis treatment tank, a second reverse osmosis treatment tank mounted on one side of the support frame, a drain pipe at the center of the top of the pretreatment tank, and a liquid injection port on the top of the pretreatment tank on one side of the drain pipe. A liquid injection hose is installed at the end of the injection pipe away from the pretreatment tank. An injection port is provided at the end of the injection hose away from the injection pipe. A pump body is installed at the top of the bottom frame between the pretreatment tank and the first reverse osmosis treatment tank. A first delivery pipe is installed at one end of the pump body, and the end of the first delivery pipe away from the pump body is connected to the bottom of the pretreatment tank. A second delivery pipe is installed at the other end of the pump body, and the end of the second delivery pipe away from the pump body is connected to the end of the first flange connection. A coarse filter layer is installed at the upper part of the pretreatment tank. An activated carbon adsorption layer is installed inside the pretreatment tank below the coarse filter layer. A precision filter layer is installed inside the pretreatment tank below the activated carbon adsorption layer.

[0006] Preferably, a rinsing port is provided at the lower end of the surface of the first reverse osmosis treatment tank, and one end of the rinsing port extends into the interior of the first reverse osmosis treatment tank. The rinsing port is provided so that cleaning fluid can be injected into the interior of the first reverse osmosis treatment tank.

[0007] Preferably, a first reverse osmosis filter cartridge is installed inside the first reverse osmosis treatment tank. The outer wall of one side of the first reverse osmosis filter cartridge is connected to one end of the first flange connection port. The first reverse osmosis filter cartridge is used to perform reverse osmosis filtration treatment on the pre-filtered water source.

[0008] Preferably, a bend is installed at the end of the second flange connection port away from the first reverse osmosis treatment tank. The end of the bend away from the second flange connection port is connected to the outer wall of the second reverse osmosis treatment tank. The bend is provided to connect the second reverse osmosis treatment tank and the first reverse osmosis treatment tank.

[0009] Preferably, the second reverse osmosis treatment tank is equipped with a second reverse osmosis filter cartridge inside. The top end of the second reverse osmosis filter cartridge is connected to one end of the bend. The second reverse osmosis filter cartridge is used to perform secondary reverse osmosis filtration on the water source.

[0010] Preferably, a U-shaped pipe is installed on the outer wall of the second infusion tube near the first flange connection port. The end of the U-shaped pipe away from the second infusion tube is connected to the outer wall of the bend. A cleaning valve is installed on the outer wall of the U-shaped pipe to allow for opening and closing of the U-shaped pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the purified water reverse osmosis filtration assembly not only extends the service life of the second reverse osmosis filter cartridge and the first reverse osmosis filter cartridge, but also reduces the phenomenon of clogging of the filtration assembly, so as to ensure the treatment effect of the filtration assembly on sewage, and significantly improves the yield and quality of purified water.

[0012] (1) By setting a coarse filter layer, an activated carbon adsorption layer and a precision filter layer in sequence from top to bottom inside the pretreatment tank, when sewage falls into the pretreatment tank through the injection pipe, large particulate impurities, residual chlorine, organic matter and other substances in the water can be removed by the coarse filter layer, the activated carbon adsorption layer and the precision filter layer, so as to reduce the burden on the subsequent second reverse osmosis filter cartridge and the first reverse osmosis filter cartridge, thereby extending the service life of the second reverse osmosis filter cartridge and the first reverse osmosis filter cartridge;

[0013] (2) By opening the cleaning valve and closing the valve on the outer wall of the bend, the cleaning liquid is injected through the flushing port, so that the cleaning liquid flows from the first flange connection port into the second infusion pipe, and the cleaning liquid flows from the second flange connection port and the U-shaped pipe into the second infusion pipe. Then the cleaning liquid flows into the pretreatment tank through the first infusion pipe. As the cleaning liquid inside the pretreatment tank increases, the dirt on the top of the coarse filter layer, the activated carbon adsorption layer and the precision filter layer will also dissolve in the cleaning liquid. Then the inclined liquid is pumped out through the drain pipe port, which can achieve backwash cleaning of the front end of the filter assembly, thereby reducing the phenomenon of filter assembly blockage and ensuring the treatment effect of the filter assembly on sewage.

[0014] (3) By installing a first reverse osmosis filter cartridge inside the first reverse osmosis treatment tank and a second reverse osmosis filter cartridge inside the second reverse osmosis treatment tank, when the pump is started, the water source after initial filtration inside the pretreatment tank can be transported to the first reverse osmosis filter cartridge through the first and second infusion pipes. The first reverse osmosis filter cartridge filters this part of the water source by reverse osmosis and then flows into the second reverse osmosis filter cartridge through the bend pipe. The second reverse osmosis filter cartridge then filters this part of the water source by reverse osmosis for a second time. Thus, the water source can be efficiently filtered by combining the pretreatment tank, thereby significantly improving the yield and quality of purified water. Attached Figure Description

[0030] A U-shaped pipe 16 is installed on the outer wall of the second infusion pipe 19 near the first flange connection port 12. The end of the U-shaped pipe 16 away from the second infusion pipe 19 is connected to the outer wall of the bend pipe 14. A cleaning valve 17 is installed on the outer wall of the U-shaped pipe 16.

[0031] In use, the cleaning valve 17 is used to open and close the U-shaped pipe 16.

[0032] A second reverse osmosis treatment tank 6 is installed on one side of the surface of the support frame 2. A drain pipe 10 is provided at the center of the top of the pretreatment tank 4. A liquid injection port 7 is provided at the top of the pretreatment tank 4 on one side of the drain pipe 10. A liquid injection hose 8 is installed at the end of the liquid injection port 7 away from the pretreatment tank 4. A liquid injection outlet 9 is provided at the end of the liquid injection hose 8 away from the liquid injection port 7. A pump body 11 is installed at the top of the bottom frame 1 between the pretreatment tank 4 and the first reverse osmosis treatment tank 5. A first delivery pipe 18 is installed at one end of the pump body 11. The end of the first infusion pipe 18 away from the pump body 11 is connected to the bottom of the pretreatment tank 4. The other end of the pump body 11 is equipped with a second infusion pipe 19. The end of the second infusion pipe 19 away from the pump body 11 is connected to the end of the first flange connection port 12. A coarse filter layer 401 is installed at the upper end of the pretreatment tank 4.

[0033] In this embodiment, the wastewater is first injected into the pretreatment tank 4 via the injection port 9 connected to the wastewater supply pipe through the injection hose 8 and injection port 7. Inside the pretreatment tank 4, a coarse filter layer 401, an activated carbon adsorption layer 402, and a precision filter layer 403 are sequentially arranged from top to bottom. When the wastewater enters the pretreatment tank 4, the coarse filter layer 401, activated carbon adsorption layer 402, and precision filter layer 403 remove large particulate impurities, residual chlorine, and organic matter from the water, thus performing preliminary filtration and effectively reducing the burden on the subsequent second reverse osmosis filter cartridge 601 and first reverse osmosis filter cartridge 501.

As the cleaning solution inside the pretreatment tank 4 increases, the dirt on the top of the coarse filter layer 401, the activated carbon adsorption layer 402, and the precision filter layer 403 will dissolve in the cleaning solution.

Finally, the first reverse osmosis filter cartridge 501 is installed inside the first reverse osmosis treatment tank 5, and the second reverse osmosis filter cartridge 60 is installed inside the second reverse osmosis treatment tank 6. 1. When the pump body 11 is started, the water source after initial filtration inside the pretreatment tank 4 can be transported to the first reverse osmosis filter cartridge 501 through the first infusion pipe 18 and the second infusion pipe 19. After the first reverse osmosis filter cartridge 501 performs reverse osmosis interception and filtration on this part of the water source, it flows into the second reverse osmosis filter cartridge 601 through the bend pipe 14. The second reverse osmosis filter cartridge 601 then performs secondary reverse osmosis filtration on this part of the water source. Thus, the water source can be efficiently filtered in conjunction with the pretreatment tank 4, thereby completing the use of the filtration component.
