Sewage filtering activated carbon filter element

Abstract

The invention relates to a sewage filtering activated carbon filter element which comprises an upper cover, a lower cover, a cylinder, filtering cotton, a filtering net and a mounting mechanism, and the upper ends of the cylinder, the filtering cotton and the filtering net, and the lower ends of the cylinder, the filtering cotton and the filtering net are respectively arranged at the lower end ofthe upper cover and the upper end of the lower cover through the mounting mechanism. The upper side and the lower side of the filtering cotton are clamped through the fixing unit, the fixing unit is movably arranged in the upper cover in a detachable mode, the filtering cotton can be directly drawn out, and therefore replacement and installation are convenient; the upper side and the lower side ofthe tail end of the filtering net are clamped through the sliding unit, then the filtering is attached to the filtering cotton by moving the tail end of the sliding unit, and thus it is guaranteed that the filtering cotton is tightly wrapped by the filtering net in the installation process, and the filtering net and the filtering cotton are prevented from loosening.

Description

technical field [0001] The invention relates to the technical field of activated carbon filter elements, in particular to an activated carbon filter element for filtering sewage. Background technique [0002] Activated carbon is used as a filter material for water filtration treatment. Due to its porosity, it can absorb fine substances in various liquids during filtration. It is often used in water treatment for decolorization, deodorization, dechlorination, removal of organic matter and heavy metals, removal of synthetic detergents, bacteria, viruses and radioactive pollutants. It is also commonly used For the tertiary treatment of wastewater, activated carbon filtration is often used in water treatment equipment filtration, sewage treatment and reclaimed water reuse, and is widely used in chemical industry, food, medicine, and electronic optoelectronics. [0003] Activated carbon filter elements are assembled from multiple filter elements, but the following problems gener...

AI Technical Summary

Problems solved by technology

[0004] (1) The activated carbon filter is mainly filtered by the activated carbon sponge, so the activated carbon sponge needs to be replaced frequently. The activated carbon sponge is installed in the middle of the activated carbon filter, and the activated carbon filter can only be replaced by disassembling the activated carbon filter, so it is not very convenient to replace

[0005] (2) Sewage enters the filter sponge through the filter net and is filtered layer by layer. If the filter sponge is not installed in place or loose, the sewage will flow out without being fully filtered by the filter sponge, thus affecting the quality of filtration.
