METAL FILTERING APPARATUS

摘要

A metal filtering apparatus that without complex structuring, permits uniform easy cleaning of multiple ceramic tubes. A pair of side boards (10, 11) are provided in unit container (2). Multiple lengthy ceramic tubes (13) are fitted between the pair of side boards (10, 11). The bottom of the unit container (2) under the ceramic tubes (13) is fitted with gas injection plate (15) having a multiplicity of gas injection apertures (16). By injection of argon gas through the gas injection apertures (16) of the gas injection plate (15), there is accomplished removing of inclusions adhering to the surface layer of the ceramic tubes (13) from the bottom side of the unit container (2).
