Embodiment 1

[0018] Such as figure 1 As shown, the water purification filter element of the present invention is cylindrical, including a housing 1, and a composite filter layer is arranged in the housing 1, and the composite filter layer is followed by a mechanical filter layer 2 and a weakly acidic cation exchange fiber layer 3 from bottom to top. (that is, ion exchange fibers containing carboxyl groups) and activated carbon layer 4; the upper and lower ends of the composite filter layer are provided with protective layer sponge pads 5. The mechanical filter layer 2 is two layers, the lower layer is a ceramic fiber layer 6, and the upper layer is an anthracite layer 7.

Embodiment 2

[0020] The water purification filter element of the present invention is in the shape of a cylinder and includes a housing in which a composite filter layer is arranged. The composite filter layer is a mechanical filter layer and a strongly acidic cation exchange fiber layer (that is, contains ion exchange fiber) and activated carbon layer; the upper and lower ends of the composite filter layer are provided with protective layer sponge pads. The mechanical filter layer is two layers, the lower layer is a glass fiber layer, and the upper layer is a zeolite layer.

Embodiment 3

[0022] The water purification filter element of the present invention is cylindrical, including a shell, and a composite filter layer is arranged in the shell, and the composite filter layer is followed by a quartz sand layer, a strongly acidic cation exchange fiber layer (that is, containing sulfonic acid groups) from bottom to top. ion exchange fiber), strong acid and weak base type amphoteric ion exchange fiber and activated carbon layer; the upper and lower ends of the composite filter layer are provided with protective non-woven mats.

Abstract

The invention belongs to the technical field of drinking water purification, and discloses a water purifying filter core comprising a housing and a composite filtering layer arranged in the housing. The composite filtering layer comprises components of, from bottom to top: a mechanical filtering layer, an ion exchange fiber layer, and an active carbon layer. With the water purifying filter core, impurities such as sediments, rusts, trace organic pollutants, and especially heavy metal ions can be removed; and water quality can be deeply purified with a good effect. The filter core can be applied in standardized productions. The filter core can be used in civil-use water purifiers and large water quality purifying apparatuses.

Description

technical field [0001] The invention belongs to the technical field of drinking water purification, and in particular relates to a water purification filter element made of adsorption materials. Background technique [0002] With the development of society and economy in our country, the problems of water resource shortage and water environment pollution are becoming more and more serious. Drinking water sanitation incidents occur from time to time, especially the threat of heavy metal ion pollution, which seriously affects human health. Therefore, the safety and sanitation of drinking water has attracted great attention from all walks of life. There are many ways to purify drinking water, and water purification devices using adsorption and filtration methods have gradually become a necessity in people's lives. As the core component, the structure, composition and performance of the filter element affect the use and effect of the water purification device. General drinking...
