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

technical field [0001] The invention specifically relates to an O-type filter. Background technique [0002] At present, there are D-type filters and D-type filters in the water treatment process, and the comet-type fiber filter material is used as the filter material. 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 itself is relatively thin, and it needs to be water-sealed during filtration to form a filter layer. It is compacted and tends to clump together. The filter backwash is to distribute water and air through the long-handled filter head, but due to the large gap between the filter head and the filter head, a backwash dead zone is formed, and the filter material is not cleaned cleanly, which not only wastes the backwash In sev...

AI Technical Summary

Problems solved by technology

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
