Preferably, in above-mentioned backwash laminated filter, the housing is made up of engineering plastics.
The beneficial effects of the utility model are：The utility model provides a kind of backwash laminated filter, including housing and
Positioned at the filter core of enclosure interior, the filter core includes that support and the multiple annular filter discs being enclosed within support stack composition
Filtering group, is equipped with intensive, helically divergent shape groove, and be on two anchor rings on two anchor rings of the filter disc
Existing spiral diverging is in opposite direction, and the support is that the hollow out position on hollow out tubular, and the support is provided with screen pack, described
Support is respectively arranged at two ends with fixture and fastener, and the fixture is located between the support and the fastener, described
Fastener is threadedly coupled with the support, and the fixture and the fastener be it is hollow.During work, current are by folded
Filter disc together, because the two sides of filter disc is equipped with groove, when water is passed therethrough, solid suspension, organic matter in water etc.
Impurity is retained down, so that water is purified, the water after purification flows through support, because the hollow out of support was provided with
Filter screen, again to Water warfare, bilayer purification improves the depuration quality of water to screen pack, and lamination and filter screen are in same housing,
Simple structure, it is easy for installation, reduce the cost.
