Title: Sponge filter device for purifying water
Inventor: SHIRASE KOZO
IPC: B01D39/16
Filed: 1995-04-07
Abstract: PURPOSE: To shorten the time for purifying water by composing a sponge filter of a large-pore filter body which has open pores of large porosity and comes into direct contact with a filter pipe and a small-pore filter body which forms the outside layer thereof and has open pores of small porosity. CONSTITUTION: The sponge filter is composed of the large-pore filter body 11 which has the open pores of the large porosity and the small-pore filter body 12 which forms the outside layer thereof and has the open pores of the small porosity. The sponge filter is provided with a communicating hole 14 into which the filter pipe 13 having plural pieces of holes 13b is passed. The sponge filter device is mounted in a water tank. The water passes the small-pore filter body 12 of the outside layer and the large-pore filter body 11 and is introduced into the filter pipe 13 when the water is lifted with air by an air supply pipe 7. The water is returned into the water tank through a water introducing pipe 4. The dust and suspended materials in the water sucked in the process are filtered by the small-pore filter body 12 and stays there.  The purified water is introduced through the large-pore filter body 11 to the filter pipe 13 without the occurrence of the clogging.
