Novel efficient water-purifier double-section filter element

Abstract

The invention provides a novel efficient water-purifier double-section filter element, and belongs to the technical field of filter elements. The novel efficient water-purifier double-section filter element comprises an upper filter element section and a lower filter element section which are connected with each other. The upper filter element section is a kieselguhr ceramic filter element, the lower filter element section is a silver ion active carbon felt filter element, and to-be-purified water flows through the upper filter element section and the lower filter element section in sequence. According to the double-section filter element in the technical scheme, the technology that the kieselguhr ceramic filter element is combined with the silver ion active carbon felt filter element is adopted, the purifying effect is remarkably improved, and the problem that an existing double-section filter element is insufficient in filtering is completely solved.

Description

technical field [0001] The invention relates to the technical field of filter elements, in particular to a novel high-efficiency double-section filter element for water purifiers. Background technique [0002] The double-section filter element in the prior art is composed of a polypropylene melt-blown upper barrel filter element and a coconut shell charcoal particle lower barrel filter element, wherein the lower barrel filter element can also be a sintered carbon rod or a compressed carbon rod. This filter element has the following defects : [0003] There are defects in the filter element of the upper barrel: 1. The filter element of the upper barrel is very easy to breed bacteria and become a hotbed of bacteria. The water coming out of the nozzle has obvious odor; 2. The filter element of the upper bucket has a low filtration accuracy, generally 1-5 μm, which cannot intercept bacteria; 3. The filter element of the lower bucket has a strong ability to hold dirt. Due to the...

Problems solved by technology

[0003] There are defects in the filter element of the upper barrel: 1. The filter element of the upper barrel is very easy to breed bacteria and become a hotbed of bacteria. The water coming out of the nozzle has obvious odor; 2. The filter element of the upper bucket has a low filtration accuracy, generally 1-5 μm, which cannot intercept bacteria; 3. The filter element of the lower bucket has a strong ability to hold dirt. Due to the deep layer of dirt, it becomes a breeding ground for bacteria and cannot be cleaned. ;

[0004] There are defects in the filter element of the lower barrel: 1. The filter element of the lower barrel has the same shortcomings as the filter element of the upper barrel; 2. In addition to the above, the ability of the filter element of the lower barrel to remove heavy metals is extremely limited
