AI Technical Summary

Technical Problem

Existing well water purification equipment has poor adaptability to confined spaces, cannot provide continuous water supply, is difficult to operate and maintain, has high energy and water consumption, and is not suitable for water quality, thus failing to meet the multiple needs of rural self-built houses, village and town settlements, and other scenarios.

Method used

The equipment adopts an integrated vertical tank with three-stage sealed independent filtration chambers, a single-chamber independent backwashing system, and a graded water quality protection bypass structure that does not require shutdown. This achieves a compact design and efficient purification. The three-stage sealed independent chambers and graded bypass design ensure the stability of the purification process and continuous water supply, reducing the difficulty of operation and maintenance and energy consumption.

Benefits of technology

It achieves stable effluent quality, reduces operation and maintenance costs and energy consumption, is suitable for installation in confined spaces, meets the simple operation and maintenance needs of non-professionals, and ensures the continuity and efficiency of the well water purification process.

Abstract

This invention belongs to the technical field of water treatment equipment, specifically disclosing a three-stage sealed well water filter. It effectively addresses technical challenges in well water purification processes in rural self-built houses, village and town settlements, and suburban communities, such as limited space, weak maintenance capabilities, and fluctuating water quality. The equipment adopts an integrated vertical cylindrical tank and supporting leg structure. The tank is equipped with a horizontal, sealed, waterproof baffle, dividing it from top to bottom into three independent, sealed, and non-cross-flow filtration chambers. Each chamber is independently equipped with water distribution, collection, venting, monitoring, and maintenance components, and is equipped with independent backwashing pipelines, bypass direct-connection pipelines, and dual-control valve groups completely isolated from the filtration pipelines. This allows for precise backwashing of a single chamber while the remaining chambers continue filtration via bypass, ensuring uninterrupted well water purification. All pipelines, valves, monitoring, and maintenance components are integrated and arranged layer by layer along the tank sidewall, with no external redundant structures, allowing for wall-mounted installation and significantly saving floor space. This invention achieves low-consumption, stable-quality, non-stop operation, and small-footprint operation of well water purification through a collaborative design of three-level sealed chambers, independent backwashing of each chamber, bypass without stopping the machine, and integrated sidewalls of all components. It is suitable for well water purification scenarios such as self-built houses in rural areas, village and town settlements, suburban communities, and small processing plants.
