DEVICE FOR FILTERING BOTTOM SEDIMENTS Russian patent published in 2023 - IPC B01D29/15 C02F11/12 

FIELD: waste treatment.

SUBSTANCE: invention relates to the field of equipment for collecting, cleaning and thickening bottom sediments of structures, stormwater, industrial runoff, sediments of rivers and lakes, as well as bottom sediments of slag dumps. A device for filtering bottom sediments contains a container, a perforated basket placed in the container, and filter material placed in the basket. The basket is mounted with a gap from the bottom and the walls of the container. The filter material is made in the form of a closed bag placed in the basket. A sleeve is mounted in the upper part of the bag to connect the internal volume of the bag to the bottom sediment supply pipeline. In the wall of the container, in its lower part, there is an unloading hatch, the window of which is hermetically connected to the unloading hole made in the part of the bag corresponding to the unloading hatch with the possibility of unloading the solid fraction of bottom sediments from the bag through the unloading hatch. To drain the filtrate, there are drain holes in the lower part of the container below the bottom of the basket. The bag is mounted to the container or the basket with a quick-release connection.

EFFECT: ability to create an efficient industrial device for filtering bottom sediments with reusable filter material.
