Abstract

The invention relates to the technical field of filter elements of water purifiers, in particular to a multi-grade activated carbon sintered filter element and a manufacturing method thereof. A filter cylinder comprises at least two filtering layers; each filtering layer is made of mixed and sintered activated carbon powder of different particle sizes, a KDF filter material of different particle sizes and ultra-high molecular weight polyethylene powder; the cross section of each filtering layer takes the shape of a plurality of coaxial circular rings different in internal diameter; the particle size of the filtering layer of the outer side is larger than that of the inner side. The activated carbon powder and the KDF filter material are mixed, the filtering layers with different filtering precisions are manufactured according to different particle sizes of the activated carbon powder, and each filtering layer has the functions of filtering and removing chlorine, so that a residual chlorine removal effect of the activated carbon powder can be improved effectively; the diameters of fine pores decrease from the outside to inside in the radial direction, so that the filter element is of a gradually-compact structure of which the outside is sparse and the inside is compact so as to realize graded filtering, and the filter element has the advantages that the capability of accommodating particle impurities in water can be improved effectively, the filtering precision of the filter element can be improved, the filter element can resist pollution and plugging, and the service life of the filter element can be prolonged.

Description

Technical field: [0001] The invention relates to the technical field of water purifier filter elements, in particular to a multi-gradient activated carbon sintered filter element and a manufacturing method thereof. Background technique: [0002] Tap water mostly uses natural river water and groundwater as water sources, and often contains some colloids, algae, and even some organic substances and metal ions produced by industry. Numerous disease cases have proved that some indicators of drinking water quality exceeding the standard will cause health damage. At the same time, as the most commonly used high-efficiency and low-cost tap water fungicide, chlorine is still widely used in many countries, and a certain concentration must be maintained at the end of the pipe network Residual chlorine for sterilization. The pungent smell of chlorine can make people feel bored and disgusted, especially in summer when the temperature is high and the bacteria multiply quickly. The conce...
