摘要
A method and apparatus for filtering contaminating particles from a liquid/particle mixture. A hollow tank is provided having a peripheral side wall and top and bottom ends. An inlet opening is in the wall adjacent the top adapted to be connected to a source of the liquid/particle mixture. An outlet opening is in the side wall spaced from the inlet opening and intermediate the top and bottom of the tank. A sealable drainage opening is at the lower end of the tank. A filter is mounted in the tank essentially perpendicular to the inlet opening and around a substantial portion of the periphery of the tank. The mounted filter is open at both ends and has filtering apertures in its side. The inlet opening is positioned so that the mixture is introduced in one open end of the filter. Filtered liquid from the mixture passes through the apertures in the side and through the outlet opening and collected portions can be dumped from the outer end through the drainage opening when it is unsealed. The tank and the filter dimensions are predetermined so that the mixture from the fluid source passes through the inlet opening and into contact with the filter with a desired velocity and the separation of the liquid and particles in the tank is efficiently accomplished without significant clogging of the filter apertures by particles during the filtering operation.
