Abstract

The invention relates to a fiber filter, which comprises a frame, fixed support porous device inside the frame and movable porous support, the filter frame fixed on the porous device and movable porous support, and the water inlet and outlet on the frame, wherein the support has at least one downward gas collecting frame; when in washing, the collecting frame can collect the air from the lower part of filter used to wash the filter material; float force of the gas collecting frame full with air can eliminate the gravities of movable porous support and gas collecting frame, or generate more drawing force, to loose the fiber beam; in filter process, the air in gas collecting frame can be discharged, to use the gravities of support and itself and the waterflow to compress the filter beam. The invention can confirm the filter effect and reduce the valve number.

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] Application No. 98201424.4 discloses a fiber bundle filter solution. The filter is mainly composed of a housing, a movable porous plate, a fixed porous plate, and a fiber bundle. The lower porous plate is fixed on the housing, and the upper porous plate can move up and down. The movable porous plate, in order to make the movable porous plate generate downward pressure when filtering and produce upward pulling force when cleaning, a number of boxes are arranged on the movable porous plate, and the boxes can be drained and filled with water or inflated and Exhaust causes it to generate upward buoyancy and downward pressure. [0003] The main disadvantage is that it needs to add valves for filling and draining or filling and exhausting, and it also increases th...
