Conveniently cleaned percolating filter

Abstract

The invention discloses a conveniently cleaned percolating filter which comprises a filter shell. An inner cavity of the filter shell is provided with an upper partition plate and a lower partition plate, a leakage group is arranged between the upper partition plate and the lower partition plate and comprises a plurality of leakage tube components, the leakage tube components comprise tubular percolating bodies, a plurality of vertical flushing tubes are arranged on the periphery of the leakage group, one side, facing the leakage group, of each flushing tube is provided with a plurality of flushing holes, and all the flushing tubes are provided with water inlets. During cleaning, high-pressure water is injected into the water inlets and can be injected to the surfaces of the percolating bodies from the flushing tubes, so that dirt on the outer surfaces of the percolating bodies is flushed out, and the percolating bodies are cleaned. Compared with a vibrating decontamination mode, by the aid of the flushing tubes, the percolating filter has the advantages of high efficiency, low energy consumption and silence and is used for filtering and purifying 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 ...

AI Technical Summary

Problems solved by technology

However, the sand tank is difficult to clean, and it is easy to nutrient the sand tank, leading to the growth of bacteria

[0004] There is a technology that uses microporous tubular permeable body to filter swimming pool water. The filtering effect is very good, but it is not easy to clean.
