An apparatus (10) is illustrated in the invention for removing coarse particles, such as sand, metal chips, etc., from a liquid, whereby the apparatus is in the first place aimed at separating coarser particles from the so called reject, which is obtained fromthe cleaning apparatuses for fiber suspensions and thus enabling a particular reutilization of the reject with its eventually remaining fiber material. The apparatus comprises a hydrocyclone (15) installed in a cylinder (20), in which the reject thereof flows out, whereby the entraining heavier particles settle and are gathered to the bottom of the cylinder (20) for discharge. The liquid rising in the cylinder flows through an overflow outlet (25) to a separate side chamber (30) open to the atmosphere, in which chamber further settling takes place. An inwardly extending pipe (40) is arranged to extend in the reject nozzle (22) of the cyclone (15). The vacuum therein extends through the inwards extending pipe, which protrudes into the side chamber (30), wherefrom liquid is redrawn to the cyclone. When desired several side chambers can be combined in series one after another for further intensification of the cleaning process. |
