Activated carbon filter element

Abstract

The invention discloses an activated carbon filter element. A spiral blade is designed between a shell and a core shaft; the spiral blade is in sliding seal with the shell; the spiral blade is fixedlyconnected with the core shaft; sealing rings are designed at contact parts of two ends of the shell and sealing surfaces of two ends of the core shaft; activated carbon is fully filled among the shell, the core shaft and the spiral blade. The spiral blade is designed so that a fluid path passing through the activated carbon becomes long; through rotating the core shaft and the spiral blade ordered arrangement of the activated carbon can be recovered again, so that the filtering effect is recovered and more activated carbon participates in a filtering process.

Description

technical field [0001] The invention provides an activated carbon filter element, which belongs to the technical field of daily household water filtration. Background technique [0002] In order to improve the quality of household water, many households are equipped with water filters. Water filters are generally composed of multi-layer filtration and activated carbon adsorption. The filters we use increase with the increase of filtration time and the increase of impurities. It is reasonable that the filtration speed should be slower and slower. On the contrary, as the use time increases, the filtration speed will become faster and faster. For the same pressure difference and filter, the faster filtration speed means that the filtration efficiency will become worse. What causes the filtering speed to become faster and the filtering effect to deteriorate? That is, the activated carbon forms a regular arrangement under the long-term water flow and only filters along this path...

[0002] In order to improve the quality of household water, many households are equipped with water filters. Water filters are generally composed of multi-layer filtration and activated carbon adsorption. The filters we use increase with the increase of filtration time and the increase of impurities. It is reasonable that the filtration speed should be slower and slower. On the contrary, as the use time increases, the filtration speed will become faster and faster. For the same pressure difference and filter, the faster filtration speed means that the filtration efficiency will become worse. What causes the filtering speed to become faster and the filtering effect to deteriorate? That is, the activated carbon forms a regular arrangement under the long-term water flow and only filters along this path with less water resistance. Over time, as the arrangement becomes more and more conducive to the passage of water, the channels become larger and larger, and the activated carbon participating in the adsorption becomes more and more The less it is, the filtering effect is greatly affected. How to solve this problem without opening the filtering device?
