COMBINED FILTER DEVICE Russian patent published in 2021 - IPC B01D29/00 C02F3/10 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a combined filter device containing a cylindrical-conical housing, pipes for tangential supply of source water, removal of purified water, removal of sludge, a filter load and a pipe under the filter load for air supply, and the filter load is located in a vibrating hopper placed inside the cylindrical part of the housing, and is attached to the rod and the power frame, the rod is fixed to the power frame and passes coaxially through the vibrating hopper, the upper end of the rod passes through the foam concentrator, foam collector and connected to a vibrator, the filter loading is a vertical filter mesh in the form of a mesh frame made in the form of a set of spirals, with different pore sizes decreasing from the outer diameter of the spiral to the inner one, on which filter fibers are fixed, there is also a conical foam concentrator and a foam collector and a foam outlet pipe in the upper part of the body, there is an inclined reflector in front of the purified water outlet pipe, and a vibrator is installed on the power frame above the foam collector, a conical reflective skirt is located in the lower part of the vibrating bunker.

EFFECT: expansion of the range of filter units.
