Description

Technical Field

[0001] This utility model relates to the field of magnetic water filter technology, and in particular to a magnetic water filter with a double-layer structure of magnet and filter screen. Background Technology

[0002] A magnetic water filter is a water treatment device that uses the principle of magnetic field adsorption to remove ferromagnetic impurities from water. High-strength magnets are installed in the water flow channel. When water containing magnetic impurities passes through, the impurities are adsorbed and trapped by the magnetic field, thereby reducing the content of ferromagnetic substances in the water and protecting downstream pipes and equipment from wear or blockage. It is widely used in industrial circulating water, groundwater pretreatment and metal processing fields, and has the characteristics of simple structure, no consumables required and convenient maintenance.

[0003] The magnetic water filter features a dual-layer structure of magnets and a filter screen. First, the magnets adsorb ferromagnetic impurities from the water. Then, the filter screen intercepts non-magnetic particles and incompletely adsorbed fine impurities, forming a double purification barrier. This structure leverages the high efficiency of magnets in adsorbing magnetic substances while the filter screen compensates for the insufficient filtration of non-magnetic impurities by a single magnetic field. This significantly improves water purification, effectively protects downstream equipment, and is suitable for water treatment scenarios with complex impurities. It is also easy to maintain, balancing filtration efficiency and practicality. However, if the magnets and filter screen are not installed correctly, large particles intercepted by the filter screen can block the magnets, affecting their adsorption of magnetic impurities. In existing technologies, the magnets are installed at the top of the filter, and the filter screen at the bottom, separated by an inclined guide plate. After water is adsorbed by the magnets, it flows slowly along the guide plate towards the filter screen, reducing the impact of turbulence on magnetic impurities. However, over time, the magnetic filter screen will adsorb a significant amount of ferrous substances, leading to accumulation and affecting filtration efficiency. Utility Model Content
