Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a multifunctional drinking water multi-media filter. Background Technology

[0002] Water treatment refers to the physical and chemical measures taken to ensure that water quality meets certain usage standards. Based on the object or purpose of treatment, water treatment is divided into two main categories: water supply treatment and wastewater treatment. When raw water is processed for domestic or industrial use, it is called water supply treatment; when wastewater is processed, it is called wastewater treatment. Water supply treatment includes both domestic drinking water treatment and industrial water treatment. For domestic drinking water (or urban public water supply), raw water from high-quality sources (well water or well-protected dedicated water supply reservoirs) only needs disinfection to become finished water. Raw water from ordinary rivers or lakes must first have turbidity-causing impurities such as silt removed, and then be disinfected to become finished water. After the initial flocculation and sedimentation processes, domestic drinking water requires final filtration and disinfection before being supplied to the market.

[0003] For example, Chinese invention patent CN222342210U, published on January 14, 2025, discloses a multi-media filter with self-cleaning function. The filter includes a multi-media filter body, a fixed plate fixedly connected to the inner wall of the filter body, a filter cap connected to the top of the fixed plate, a limiting rod fixedly connected to the top of the fixed plate, and a sealing plate fixedly connected to the top of the multi-media filter body. This invention solves the problem that most existing multi-media filters lack self-cleaning function, making it inconvenient to clean the inner wall of the filter. Furthermore, after prolonged use, the filter media is prone to adsorbing particulate matter and suspended solids on its surface and adhering to the inner wall of the filter due to contact with the filter media, leading to scaling and reduced filtration performance in subsequent use.

[0004] As can be seen from the above patents, the multi-media filter has self-cleaning and descaling functions, but it suffers from the problem of limited water treatment functions and the need to stop the filtration process for cleaning and descaling functions; therefore, this invention provides a multi-functional drinking water multi-media filter to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a multifunctional multi-media drinking water filter.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multifunctional drinking water multi-media filter includes a housing. Several electrode plates are arranged extending radially into the interior of the housing from the top center of the housing. Below the electrode plates, from top to bottom, a water distributor, a multi-media filter body, and an ion exchange resin layer are arranged sequentially. The multi-media filter body is composed of multiple layers of fillers with different particle sizes and densities, which, from top to bottom, are activated carbon, quartz sand, porous ceramics, and magnetite. Electrodes are arranged at the lower end of the electrode plates.

[0008] Preferably, the electrode plates are evenly distributed with the center of the top of the housing as the center, and with the same included angle and radius as the center.

[0009] Preferably, the exchange resin layer contains a cation exchange resin layer.

[0013] The beneficial effects of this utility model are:

[0026] Reference Figure 1-2 The present invention discloses a multifunctional drinking water multi-media filter, comprising a housing 1, an electrode plate 2, an electrode 9, a water distributor 3, a multi-media filter body 4, an exchange resin layer 5, an inlet pipe 6, an outlet pipe 7, and an electrical control unit 8; the inlet pipe 6, the electrode plate 2, the electrode 9, the water distributor 3, the multi-media filter body 4, the exchange resin layer 5, and the outlet pipe 7 are arranged sequentially from top to bottom. Several electrode plates 2, located at the radial center of the top of the housing 1, extend into the interior of the housing 1. The electrode plates 2 are electrically connected and controlled by an electronic control unit 8 located at the top edge of the outer wall of the housing 1. The inlet pipe 6 and outlet pipe 7 are used to pour in the water to be filtered and to discharge the filtered water, respectively. The water distributor 3 is used to evenly distribute the water flowing in from the inlet pipe 6 onto the multi-media filter body 4. The multi-media filter body 4 consists of multiple layers of packing material with different particle sizes and densities, arranged from top to bottom according to increasing particle size and density: activated carbon, quartz sand, porous ceramics, and magnetite. It can adsorb, trap, and settle to remove suspended solids, silt, clay, humic substances, and other impurities. The ion exchange resin layer 5 contains a cation exchange resin layer, used to react with Mg in the water. 2+ Ca 2+ An exchange process occurs, reducing the water hardness to below 70 mg / L, thus creating soft water.

[0027] In an optional embodiment, the electrode plates 2 are evenly distributed with the top center of the housing 1 as the center, and with the same angle and radius as the center, so as to form a uniform and balanced structure and generate uniform high-frequency radio waves.

[0028] In an optional embodiment, the housing 1 is a housing made of insulating material or has an insulating coating to prevent leakage.

[0029] The workflow of this utility model is as follows:

[0030] The water to be filtered enters the filter through the inlet pipe 6 and is first evenly distributed by the water distributor 3. Simultaneously, the electronic control unit 8 is activated, controlling the electrode 9 via the electrode plate 2 to generate high-frequency electromagnetic waves. When the water flows through the high-pressure, high-frequency electromagnetic field, the calcium and magnesium ions and various bicarbonate ions in the water lose their chemical, physical, and mutual attraction abilities under the influence of the high-pressure, high-frequency electromagnetic field, suspending in the water and not adhering to the filter wall, thus preventing scale formation. At the same time, the high-frequency electromagnetic waves generate turbulence in the water, disrupting the ion channels of cell membranes, changing the internal control current and environmental conditions required for cell survival, causing them to lose their ability to survive and die. Moreover, the excited water molecules can surround and block dissolved oxygen in the water, cutting off the oxygen source required for microbial life activities, thereby achieving a better bactericidal and algae-killing effect, while also preventing the formation of biological sludge. After being evenly distributed by the water distributor 3, the water sequentially passes through the multi-layer packing material (activated carbon, quartz sand, porous ceramics, and magnetite) of the multi-media filter 4. The multi-layer packing material adsorbs, traps, and settles impurities such as suspended solids, silt, clay, and humic substances in the water. Then, it passes through the ion exchange resin layer 5, where the cation exchange resin layer and the Mg in the water... 2+ Ca 2+ An exchange process occurs, reducing the water hardness to below 70 mg / L, turning it into soft water, which is then discharged from the outlet pipe 7.

[0031] Of course, the embodiments described in this specific implementation are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
