O-shaped filter chamber

Abstract

The invention particularly discloses an O-shaped filter chamber, wherein a water inlet is arranged above the filter chamber; a sewage outfall is arranged at the center of the filter chamber and communicated to two ends of the bottom of the filter chamber; one end is communicated with a water outlet; the other end is communicated with a drain outlet; a filter material intercept board is arranged at the top of the filter chamber; a filter material layer is arranged below the filter material intercept board; a filter plate is arranged below the filter material layer; a water distributing filter head and a backlash air pipe are arranged on the filter plate; and an air inlet is arranged at the lower wall of the filter chamber and arranged above the water outlet. By adopting the O-shaped filter chamber, a fiber filter chamber is formed into an O shape of a capital letter; and two ends are formed into arcs, so that the running resistance of the filter material is effectively reduced. The sewage outfall, an outlet channel and a backlash intake channel are merged together, formed into a mode of a guide wall, and put in the middle of the filter chamber, so that not only is the floor area of the filter chamber effectively reduced, but also a 'track' can be provided for movement of the filter material, so as to play a guide role.

Description

[0001] technical field [0002] The invention specifically relates to an O-shaped filter tank. Background technique [0003] Now there are D-type filters in the water treatment process, and D-type filters use comet-type fiber filter materials as filter materials. The comet-type fiber filter material has a large amount of dirt, and the speed of the D-type filter can generally reach 20-25m / h, which is 3 to 4 times that of the traditional quartz sand filter. However, due to the structural characteristics of the fiber filter material itself, the fiber filament itself is relatively thin, and it needs to be water-sealed to form a filter layer when filtering. It is easy to be compacted into blocks. The backwashing of the filter is to distribute water and gas through the long-handled filter head, but because there is a large gap between the filter heads, a backwashing dead zone is formed, and the filter material is not cleaned, which not only wastes backwashing In severe cases, i...

However, due to the structural characteristics of the fiber filter material itself, the fiber filament itself is relatively thin, and it needs to be water-sealed to form a filter layer when filtering. It is easy to form a block when compacted

The backwashing of the filter is to distribute water and gas through the long-handled filter head, but because there is a large gap between the filter heads, a backwashing dead zone is formed, and the filter material is not cleaned, which not only wastes backwashing In severe cases, it will affect the water quality of the effluent and reduce the service life of the filter material
