Problems solved by technology

[0002] At present, the known water plant filters all adopt filter materials, filter plates, and filter head devices installed in the filter body, and there are common problems such as large amount of backwash water, long backwash time and cycle, poor effluent quality, and infrastructure construction. More investment, higher operating costs and other disadvantages

Embodiment Construction

[0018] In Figures 1 to 10, the flap filter consists of the filter body 5, the backwashing system, the filtration system and the sewage system installed in the filter body 5 from bottom to top, and the backwashing system, the filtration system and the sewage system installed on the filter body 5. The water inlet and outlet system is composed. The backwash system includes a backwash valve 1 and a flush air valve 4. The filter system includes an anthracite coal layer 8, a quartz sand layer 9, a coarse sand layer 10, and a pebble layer 11 arranged from the top to the bottom, from the fine layer to the coarse layer. The water inlet and outlet system includes an overflow weir plate 2, a water outlet valve 3 and a water channel. The backwashing system also has the positioning steel plate 16 fixed in the filter body 5 and the water distribution straight pipe 7 and the air distribution straight pipe 15 on the pallet 17, and the water distribution cloth fixed on the top of the water distrib...

Abstract

The present invention relates to a filter characterizing mutually arranged filter elements, and is especially tilting plate type filtering pool for use in water works. The tilting plate type filtering pool consists of filtering pool, reverse flush system, filtering system, sewage draining system and water influent and effluent system. The reverse flush system includes reverse flush valve, flushing air valve, water and air distributing transverse pipes, water distributing longitudinal pipes and air distributing longitudinal pipes; the filtering system includes anthracite layer, quartzite layer, coarse sand layer and pebble layer; the water influent and effluent system includes overflow weir plate, water effluent valve and water canal; and the sewage draining system includes tilting plate valve and canal. The present invention has less reverse flush water amount, short reverse flush time, high water effluent quality, low cost and other advantages.

Description

Technical field [0001] The invention relates to a filter with a plurality of filter elements characterized by mutual arrangement, in particular to a flap type filter tank used in a water plant. Background technique [0002] At present, the well-known filter tanks of water plants all adopt the installation of filter media, filter plates, and filter head devices in the filter body. There are generally large amounts of backwashing water, longer backwashing time and cycles, poor effluent quality, and infrastructure. Disadvantages such as higher investment and higher operating costs. Summary of the invention [0003] In order to overcome the above-mentioned drawbacks of the existing water plant filter, the present invention provides a flap type filter, which has less backwash water consumption, shorter backwash time and cycle, better effluent water quality, and infrastructure investment. Advantages such as less and lower operating costs. [0004] The technical solution adopted by the...
