Description

Technical Field

[0001] The utility model relates to the technical field of water supply treatment, in particular to a water quality purification device for water supply treatment. Background Art

[0002] A water purification device for water treatment can effectively purify water and ensure the quality and safety of drinking water and industrial water. In existing water purification devices, only a single-layer filtration method is usually used to purify water. This single-layer filtration has some problems, including poor treatment effect and inability to effectively remove fine particles and microorganisms. The complexity of water quality makes it difficult for single-layer filtration to meet the purification needs under different water quality conditions, especially for water sources containing a large amount of suspended matter or specific chemicals. The treatment effect is more limited. Existing water purification devices can often only treat water at a fixed flow rate and cannot adjust the flow rate according to the actual water quality conditions or treatment needs. Too fast a water flow rate may cause the filter medium to be unable to effectively capture fine particles, while too slow a water flow rate may reduce the overall purification efficiency.

[0028] In this embodiment, a mounting plate 14 is provided at one end of the purification pipe 1 away from the connecting pipe 8, a support rod 15 is provided inside the mounting plate 14, valve leaves 16 are rotatably provided on both sides of the support rod 15, and a convex ring 17 is provided on the inner side of the mounting ring 10. When the water flows back in the purification pipe 1, the valve leaf 16 will rotate inwardly with the thrust of the water flow, and the convex ring 17 can block the valve leaf 16, so that the valve leaf 16 and the mounting plate 14 form a closed space, prohibiting the water from flowing back. Preventing the water from flowing back can effectively avoid problems such as backflow or reverse flow in the system, thereby protecting the safe and stable operation of the water purification device and the pipeline system.

[0029] In this embodiment, a bellows 18 is connected to the outer end of the regulating tube 9. The bellows 18 has a certain flexibility, which makes installation more flexible and convenient, and can adapt to pipeline deviations and deformations within a certain range, thereby reducing installation costs and time.

[0030] In this embodiment, flanges 19 are provided at the outer ends of the purification tube 1 and the bellows 18. The flanges 19 can provide a uniform connection surface and a tight seal to ensure that the connection will not loosen or leak due to vibration or pressure changes, thereby enhancing the connection stability of the system.

[0031] In this embodiment, the particle size of the sand and gravel filter layer 4 can be selected and adjusted as needed to adapt to different water qualities and filtering requirements.

[0032] In this embodiment, the ceramsite filter layer 6 can be reused by cleaning and regenerating, thereby reducing the operating cost and improving the economy of the equipment.

[0033] In this embodiment, the polymer filter layer 7 can be designed to have specific chemical selectivity as required, so as to remove specific chemical substances or adjust the pH value of water.

[0034] In this embodiment, the multiple groups of elastic sheets 11 are all made of fluororubber, which has excellent high temperature resistance, oil resistance and chemical corrosion resistance and is often used in the manufacture of seals in high temperature, high pressure and strong corrosion environments.

[0035] Embodiment 2:

[0036] In summary, when in use, the flange 19 is connected and installed with the external water pipe, so that the water flow is transported to the purification pipe 1, and the adjusting cap 13 is threadedly connected with the adjusting pipe 9, so that the adjusting cap 13 is screwed to drive the adjusting pipe 9 to move into the connecting pipe 8, and the top of the adjusting pipe 9 abuts against the multiple groups of elastic sheets 11 to open it outward, thereby reducing the blocking area of ​​the elastic sheets 11 on the water flow, so that the flow rate of the water flow can be adjusted. When the water flows through the purification pipe 1, the particulate impurities in the water flow are filtered through the filter screen 2, and the larger particles and suspended matter in the water flow are further filtered through the sand and gravel filter layer 4, and then the activated carbon filter layer 5 is used to filter the water flow. It has a strong adsorption capacity and can remove pollutants such as organic matter, odorous substances and some heavy metals in the water. After that, it passes through the ceramsite filter layer 6 with a uniform pore structure, which can be used to remove tiny particles and bacteria. The polymer filter layer 7 removes specific chemicals or adjusts the pH of the water. When the water flows back in the purification pipe 1, the valve leaf 16 will rotate inward with the thrust of the water flow, and the convex ring 17 can block the valve leaf 16, so that the valve leaf 16 and the mounting plate 14 form a closed space, prohibiting the water from flowing back. Preventing the water from flowing back can effectively avoid problems such as backflow or backflow in the system, and protect the safe and stable operation of the water purification device and the pipeline system.

[0037] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded.
