Percolating filter

Abstract

The invention discloses a percolating filter. The percolating filter comprises a filter casing, wherein an upper partition and a lower partition are arranged in an inner chamber of the filter casing;flushing pipes are arranged between the upper partition and the lower partition; leak pipe assemblies uniformly distributed around the flushing pipes are arranged between the upper partition and the lower partition; each leak pipe assembly comprises a pipy percolating body, and water out of the percolating body can enter a pipe chamber of the percolating body through a percolating gap. During use,swimming pool water enters the filter casing from a pool water inlet, percolates the pipe chambers of the percolating bodies and flows out of a water filter port, foreign matter cannot pass through the percolating bodies, and water filtration is realized. During cleaning, high-pressure water is introduced into the flushing pipes and sprayed out from through holes in the flushing pipes to flush outer walls of the percolating bodies. By means of the flushing pipes, the mode of the filter has the characteristics of being high in efficiency, low in energy consumption and noiseless as compared with a vibration decontamination mode. The percolating filter is used for filtering and purifying the swimming pool water.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a device for filtering and purifying swimming pool water by means of osmosis. Background technique [0002] Swimming pools use a lot of water. For cost reasons, the swimming pool water will not be replaced all the time. Therefore, it is necessary to filter the water in the swimming pool and physically filter the foreign objects and impurities in the water. [0003] Existing swimming pool filtration equipment often uses sand tanks to filter. Generally, a certain scale of quartz sand is placed in the sand tank. The size and specifications of the quartz sand are different within a certain range. In the sand tank, the quartz sand is from top to bottom, from small to The water is arranged in this way. During normal filtration, water enters from the upper layer of sand and comes out from the lower layer. When water flows through the filter layer from above, part of the solid suspended ...
