Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon filters, in particular to a granular activated carbon filter element. Background Art

[0002] The activated carbon particle filter element is filled in a plastic filter shell container without any chemical additives. There are multiple layers of ultra-fine fiber non-woven fabrics at the upper and lower entrances of the container to prevent the release of carbon powder. The shell is made of ABS material and ultrasonic welding process. Since the liquid flows from bottom to top, the liquid contacts the activated carbon particle layer for a long time and over a wide area, so it can effectively play the role of dechlorination, deodorization and deodorization.

[0003] The activated carbon filter element is to put the required activated carbon particles into a special plastic shell, and weld the end caps to the two end faces of the shell with welding equipment. Non-woven filter discs for filtering are placed at both ends of the shell to ensure that the carbon core will not drop carbon powder and black water when in use. The shell end caps can be made into different types of connectors as needed.

[0004] The existing granular activated carbon filter element has certain deficiencies during use. Since the activated carbon filter element loads the required activated carbon particles into a special plastic shell, and the end caps are welded to the two end surfaces of the shell with welding equipment, the activated carbon filter is a disposable product. When the activated carbon becomes saturated during use, the activated carbon filter element loses its filtering effect and needs to be replaced with a new activated carbon filter, which causes a waste of the plastic shell and the end caps, which is not conducive to saving resources.
