Description

Technical Field

[0001] The utility model relates to the technical field of floating body filters, in particular to a floating body filter with a built-in axial flow impeller. Background Art

[0002] The drum-type floating filter is a filtering device that floats in the water. It filters the water by rotating the filter cartridge, thereby purifying the water.

This filter omits the motor drive structure and sets a built-in impeller in the drum. However, the blades of the built-in impeller are driven radially by the water body. Although passive rotation of the drum can be achieved, the rotation effect is not ideal, which affects its filtering effect. Utility Model Content
