CN223716622U - A multi-layer filtration structure for wastewater treatment - Google Patents

Abstract

This utility model relates to the field of filtration structure technology, specifically to a multi-layer filtration structure for wastewater treatment. The solution includes a filter box, with a cover plate bolted to the top of the filter box, and an inlet pipe fixedly connected to the top of the cover plate. Two pairs of support seats are fixedly connected to the bottom of the filter box. The interior of the filter box contains a first V-shaped filter screen and a second V-shaped filter screen. Compared to existing technologies, this application, through a designed squeezing mechanism combined with a connecting rod and a hammer, can drive the first and second V-shaped filter screens to move repeatedly up and down. This allows impurities to fall along the inclined surfaces of the first and second V-shaped filter screens into the collection frame, reducing accumulation and clogging. Simultaneously, the hammer's up-and-down movement repeatedly strikes the bottom of the filter box, generating vibration to dislodge impurities accumulated on the surface of the circular filter screen, further reducing the possibility of clogging and ensuring effective filtration.
