Trash tolerant filter support for a disc filter |
摘要 |
A filter device for filtering a liquid which includes trash. The device includes a drum for receiving the liquid and trash, wherein the drum includes at least one drum aperture. The device further includes a first pair of filter panels which are adapted for filtering the liquid. The filter panels are spaced apart to form a cavity for receiving the liquid and trash. The device further includes a frame for supporting the filter panels, wherein the frame is coupled to the drum. The frame includes a frame aperture wherein the frame aperture and the cavity form a volume having a cross sectional area sized substantially equal to or greater than the drum aperture and wherein said volume extends to a second pair of filter panels to enable liquid and trash which pass through the drum aperture to also pass through the frame aperture to the second pair of filter panels. |

1. A filter device for filtering wastewater, the device comprising:
a drum for receiving the wastewater, the drum including a plurality of drum apertures; a frame comprising a plurality of frame supports each having an attachment portion coupled to the drum and a radial strut portion extending from the attachment portion, each of the plurality of frame supports defining a single frame aperture that extends through the attachment portion and along an entire length of the radial strut portion to correspond with the shape of the frame support; and a plurality of adjacent filter segments positioned around the drum, each of the plurality of adjacent filter segments defining a cavity in fluid communication with at least one of the plurality of drum apertures and supported at a first side by a first frame support and at a second side by a second frame support, the plurality of frame apertures and cavities arranged to form a circumferential open fluid channel extending continuously around the drum to enable water to pass relatively unimpeded through the plurality of drum apertures and through the plurality of adjacent filter segments. |
