Abstract
(EN)
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).

La présente invention concerne un appareil de filtration de métal qui, tout en étant dépourvu d'une structure complexe, permet de nettoyer de manière aisée et uniforme de multiples tubes en céramique. Une paire de panneaux latéraux (10, 11) sont disposés dans un récipient unitaire (2). Les multiples tubes allongés en céramique (13) sont fixés entre la paire de panneaux latéraux (10, 11). Le fond du récipient unitaire (2) situé sous les tubes en céramique (13) est fixé à une plaque d'injection de gaz (15) dotée d'une multitude d'ouvertures d'injection de gaz (16). Le fait d'injecter de l'argon par les ouvertures d'injection de gaz (16) de la plaque d'injection de gaz (15) permet de retirer les inclusions qui ont adhéré à la couche superficielle des tubes en céramique (13) sur le fond du récipient unitaire (2).
