Description

Technical Field

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

[0002] Water treatment equipment utilizes reverse osmosis membrane separation technology, working in conjunction with a pre-treatment system. Through high-pressure pumps and the retention capacity of the reverse osmosis membrane, it effectively removes dissolved solids, organic matter, colloids, microorganisms, and bacteria from the water. It boasts excellent performance characteristics such as wide applicability, high automation, small footprint, low energy consumption, and high-quality effluent.

[0003] However, when water treatment equipment processes water, if the water hardness is too high, the filter pores will become clogged during the process of intercepting impurities, resulting in a decrease in the filtration effect and efficiency, thus affecting the overall treatment effect of the water treatment equipment.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please refer to Figure 1-6 ;

[0030] A water treatment filtration device includes a reverse osmosis system 3, an upper three-way valve 7, a lower three-way valve 8, and a cleaning system 9. The reverse osmosis system 3 includes several housings 31 and reverse osmosis units disposed within the housings 31. The housings 31 are arranged in parallel, with one end connected to a distribution pipe 2 and the other end connected to a manifold 4. The distribution pipe 2 is connected to a water supply module 1 for distributing raw water to each housing 31. Simultaneously, the distribution pipe 2 is equipped with several product water pipes 5 for outputting filtered water. The product water pipes 5 are connected to a product water tank 100 via a manifold 6. Filtered purified water enters the product water pipes 5 and is uniformly transported to the product water tank 100 via the manifold 6, achieving the collection and storage of purified water.

[0031] The upper three-way valve 7 includes an upper port 1 71, an upper port 2 72, and an upper port 3 73, wherein the upper port 1 71 is connected to the diverter pipe 2. The lower three-way valve 8 includes a lower port 1 81, a lower port 2 82, and a lower port 3, wherein the lower port 1 81 is connected to the manifold pipe 4. The cleaning system 9 is connected to the upper port 2 72, lower port 2 82, upper port 3 73, and lower port 3 83 via pipes to achieve switching between different cleaning modes. In addition, the cleaning system 9 is also connected to the manifold pipe 6 via the diverter pipe 2 95 to introduce water during the cleaning process.

[0032] The equipment operates in three modes: normal water production, backwashing, and forward washing.

[0033] Normal water production mode: Close the upper port 2 72 and upper port 3 73 of the upper three-way valve 7 and the lower port 2 82 and lower port 3 83 of the lower three-way valve 8, so that both the upper three-way valve 7 and the lower three-way valve 8 are in the cut-off bypass state, ensuring that the water flow only runs along the main filtration path. Start the water supply module 1, and the raw water enters the branch pipe 1 2 through the pipeline. The branch pipe 1 2 serves as the raw water distribution main pipe, delivering the raw water to each parallel housing 31. Under pressure, the raw water is filtered through the reverse osmosis unit in the housing 31, and the resulting purified water is collected through the product water pipe 5 to the manifold 2 6, and finally delivered to the product water tank 100 for user use.

[0034] Backwashing Operation Mode: When the reverse osmosis unit needs to be backwashed, first shut off the water supply module 1, then close the upper port 3 73 of the upper three-way valve 7 and the lower port 2 82 of the lower three-way valve 8, while simultaneously opening the upper port 1 71 and upper port 2 72, and the lower port 1 81 and lower port 3 83. Start the cleaning system 9, and the cleaning medium flows into the housing 31 sequentially through the lower port 3 83, the lower port 1 81, and the manifold 4, flushing the dirt and deposits on the surface of the reverse osmosis unit from bottom to top. The wastewater generated during flushing is discharged from the other end of the housing 31, enters the diversion pipe 2, and then returns to the cleaning system 9 through the upper port 1 71 and port 2 72, forming a closed-loop backwashing process, effectively removing contaminants from the membrane surface.

[0035] Forward cleaning operation mode: When forward cleaning is required, close the water supply module 1, the upper port 2 72 of the upper three-way valve 7, and the lower port 3 83 of the lower three-way valve 8. At the same time, open the upper port 1 71 and upper port 3 73 of the upper three-way valve 7, and the lower port 1 81 and lower port 2 82 of the lower three-way valve 8. After starting the cleaning system 9, the cleaning medium flows into the housing 31 through the upper port 3 73, the upper port 1 71, and the diversion pipe 1 2, flushing the impurities and residues inside the reverse osmosis unit from top to bottom. The flushing wastewater is discharged from the other end of the housing 31 into the manifold 4, and then flows back to the cleaning system 9 through the lower port 1 81 and lower port 2 82 to participate in the next round of forward cleaning cycle.

[0036] The water treatment filtration equipment of this application achieves flexible switching between water production and cleaning modes through the coordinated control of the upper three-way valve 7 and the lower three-way valve 8, ensuring the filtration performance and stability of the reverse osmosis system 3 during long-term operation, thereby extending the service life of the reverse osmosis system 3.

[0037] In this embodiment, the reverse osmosis unit includes a reverse osmosis membrane 32 disposed within the housing 31. The reverse osmosis membrane 32 is wound around a central tube 33, one end of which is sealed, and the other end is sealed and connected to the corresponding product water pipe 5, forming a water guiding channel. Preferably, the central tube 33 has multiple through holes on its wall. When raw water is filtered through the reverse osmosis membrane 32 under pressure, the resulting purified water permeates through the membrane surface and enters the membrane interior. Subsequently, it enters the inner cavity of the central tube 33 through the through holes on its surface and flows axially along the central tube 33, finally entering the product water pipe 5 to achieve the delivery of filtered water.

[0038] In this embodiment, the water supply module 1 includes a sand and carbon tank 11 and a water pump 12 connected by a pipeline. The raw water first enters the sand and carbon tank 11, which contains multi-media filter media such as quartz sand and activated carbon to remove suspended solids, particles, colloids, residual chlorine and some organic matter from the water, thus achieving preliminary purification of the water quality. The water pump 12 is located on the outlet side of the sand and carbon tank 11 and is used to extract the pretreated water from the sand and carbon tank 11 and pressurize and transport it to the diversion pipe 2 to provide a stable water source for the subsequent filtration process.

[0039] In addition, a switch valve 13 is connected between the water pump 12 and the sand and carbon box 11 to control the water flow during water production and cleaning, as well as the start-up, shutdown, maintenance and repair of the water treatment filtration equipment.

[0040] In this embodiment, a drain valve 41 is provided between the lower interface 81 and the manifold 4. When the forward washing operation is performed, the drain valve 41 is opened, so that most of the wastewater generated during rinsing is directly discharged to the outside through the drain valve 41 during the process of flowing through the manifold 4 to the lower interface 81, so as to achieve rapid discharge of pollutants. Only a small amount of wastewater that cannot be discharged in time flows back to the cleaning system 9 through the lower interface 81 and the lower interface 82 to participate in the next round of forward washing cycle.

[0041] In this embodiment, the cleaning system 9 includes a cleaning water tank 91, a cleaning pump 92, and a security filter 93 connected in sequence by pipes. The cleaning water tank 91 stores the cleaning fluid, the cleaning pump 92 provides circulation power for the cleaning fluid, and the security filter 93 removes suspended particles and impurities from the cleaning fluid to prevent secondary pollution of the reverse osmosis system 3. The security filter 93 is connected to the upper interface 73 and the lower interface 83 via a diversion pipe 94. According to the cleaning requirements, the filtered cleaning medium is delivered to the upper interface 73 of the upper three-way valve 7 or the lower interface 83 of the lower three-way valve 8 to realize forward or reverse washing operations.

[0042] In this embodiment, both the upper three-way valve 7 and the lower three-way valve 8 are electronic three-way valves, which can be automatically switched by the control system to accurately switch between different operating modes such as normal water production, forward washing and backwashing, thereby improving the automation level and operational reliability of the water treatment filtration equipment.

[0043] In this embodiment, the diversion pipe 2 is composed of several T-shaped pipes connected together. The connections between the T-shaped pipes, between the product water pipes 5 and the manifold 6, and between the two ends of the reverse osmosis system and the T-shaped pipes and the manifold 4 are all made by using a copy tube 200. No thread tightening or welding is required, which can achieve quick connection and disconnection.
