Abstract:
1. A sieving and fluid separation apparatus for processing a material containing fractions of fluid and solid particles, the apparatus comprising: a sieving unit capable of filtering the fluid and the solid particles from the material, and a separating unit capable of separating fluid components received from the sieving unit, wherein said sieving unit being located in a first substantially fluid-tight vessel, said separating unit being located in a second substantially fluid-tight vessel, and the first and second vessels being interconnected by means of a pipe arrangement, wherein the sieving unit comprises: a material supply portion, an endless movable web of sieve cloth communicating with the material supply portion for receiving material onto an upper face of the web, said endless web passing over at least two spaced-apart rotary rollers, yielding an upper path and a lower path of the web, a roller drive motor engaging a roller for rotation thereof, a trough-like suction device facing at least part of a lower face of the upper path of the web, the suction device communicating via said pipe arrangement with a suction pump device located on the second vessel of the separating unit to deliver by suction fluid components filtered from said material through the upper path of the web into the separating unit in the second vessel, and an outlet to remove from the sieving unit the filtered solid particles delivered by the movable web to the outlet, and wherein the separating unit comprises: a separator device inside the second vessel, a first pipe outlet means of the pipe arrangement facing the separator device to enable filtered fluid components passing from the suction device via the pipe arrangement to meet the separator device to reduce the fluid velocity and facilitate separation of the fluid components into liquid and gas thereof, a ventilation system provided at a top of the second vessel and in communication with said suction pump device and thereby an interior space of the second vessel to withdraw said separated gas therefrom, and a drain pipe communicating with the interior space of the second vessel to drain said separated liquid to a location outside the second vessel.
