Abstract

The invention relates to a fiber filter which comprises a case, a fixed support porous device inside the case, a movable porous support device, a fiber beam unit mounted on the fixed and movable porous support devices, a water inlet and a water outlet mounted on the case, a hollow case with adjustable floatage on the movable porous support device, several pipes through the case to form channels, and a fluid access pipe on the base, wherein the float is formed by several hollow cases completely or partly. The water in the hollow case can be discharged all in the filtration, then the generated floatage can fully or partly counteract the gravities of movable porous support device and the hollow case, to compress the fiber beam, and the air can be discharged by water when in washing to decrease the floatage and use the gravities of movable porous support device and the hollow case to draw the fiber beam to avoid the accumulation of fiber beam when washing from down to up, to apply the washing.

Description

technical field [0001] The invention relates to an improvement of a fiber filter or a fiber filter tank, in particular to a density adjustment control scheme of a fiber bundle filter layer. Background technique [0002] ZL92230672.9 discloses a fiber bundle filter solution. The filter is mainly composed of a housing, a movable porous plate, a fixed porous plate, and fiber bundles. The upper porous plate is fixed on the housing, and the lower porous plate is suspended by the fiber bundles. hang on the bottom. When filtering, the water flows through the filter layer formed by the fiber bundles from bottom to top. Driven by the water flow, the lower porous plate moves upward, and the lower porous plate and the fiber bundles form a denser filter layer. When cleaning, the water can flow from top to bottom and Bi-directional cleaning from bottom to top. In particular, bottom-up cleaning can more thoroughly wash off the mud and debris trapped in the upper section of the fiber bun...
