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] exist Figures 1 to 10 Among them, the flap type filter is composed of a filter body 5, a backwash system, a filtration system and a sewage system installed in the filter body 5 from bottom to top, and an inlet and outlet water system installed on the filter body 5. The backwashing system includes a backwashing valve 1 and a flushing air valve 4 . The filter system includes anthracite coal layer 8 , quartz sand layer 9 , coarse sand layer 10 and pebble layer 11 . 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 a water distribution gas horizontal pipe 13, a water distribution straight pipe 7 and a gas distribution straight pipe 15, and the blowdown system includes a flap valve 12 and a channel.

[0019] exist Figure 7 Among them, there are water holes 20, flushing air holes 21 and exhaust holes 22 on the horizontal pipe 13 for water distribution and air distribution.

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 which are characterized by mutual arrangement, especially for flap-type filter tanks for waterworks. Background technique [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. Contents of the invention [0003] In order to overcome the above disadvantages of the existing waterworks filters, the present invention provides a flap type filter, which has the advantages of less water consumption for backwashing, shorter backwashing time and cycle, better effluent quality, and lower infrastructure investment. Less, lower operating costs and other advantages. [0004] The techn...
