Filtering apparatus

摘要

The apparatus comprises a hollow casing in the form of a solid of revolution having an inlet and an outlet, a spinner for imparting rotary motion within the casing to a fluid being purified, and a hollow filter element closed at one end, positioned coaxially within the casing and snugly fit with the open end in the outlet of the casing. The apparatus also includes a discharge connection piece for removal of the impurities that have been separated from the fluid being purified. The spinner is positioned at the inlet, and the discharge connection piece is attached to the lower portion of the casing. The filter element and the casing define a space tapering from the inlet toward the outlet, and the filter element being a frame with a covering having a water-repellent polymeric foam material applied thereto.
