AUTOMATIC CLEANING TYPE WATER TREATMENT FILTER STRUCTURE

摘要

The present invention relates to an automatic cleaning type water treatment filter which is capable of automatically cleaning foreign substances remaining on the surface of the water treatment filter using buoyancy due to the water level change of contaminated water in the water treatment filter. To achieve said purpose, the present invention provides the water treatment filter (20) which is installed inside a water treatment housing (10) for the purification of the contaminated water which flows in through an inlet pipe (11) from the outside and comprises a cleaning unit (30) for removing the foreign substances from the surface of the filter and cleaning the filter by being installed on the outer wall of the water treatment filter (20) to be slid in a vertical direction. A floating body (40) is integrated to the cleaning unit (30) for generating ascending power due to buoyancy. [Reference numerals] (AA) Pretreatment tank; (BB) Filter tank
