Since it is fixed to the movable part (the second fiber fixing part provided on the movable part), when the fluid to be treated is supplied into the outer cylindrical part from above the outer cylindrical part (during the filtration process), the fiber filtering material part is consolidated by the flow energy of the processing fluid and the weight of the in-cylinder movable part formed in the bowl shape, and the filtering process for the fluid to be processed can be performed with high efficiency.

That is, according to such a configuration, since the in-cylinder movable part is formed in the bowl shape, air accumulates on the inner side (the concave part), and the in-cylinder movable part has buoyancy, The upper end of the fiber filter part fixed to the in-cylinder movable part is pulled upward. As a result, the fiber filter part is efficiently extended, and the extended fiber filter part is washed with high efficiency. It will be.

Abstract

La présente invention aborde le problème de la fourniture d'un dispositif de filtration qui a une partie de matériau de filtre à fibre et qui est capable de réaliser un traitement de filtration et un traitement de lavage avec une efficacité élevée sur la base d'une configuration relativement simple sans utiliser de moyen électrique. La présente invention est un dispositif de filtration qui a une partie de matériau de filtre à fibre et qui est caractérisé en ce qu'il comprend: une partie cylindrique externe qui enferme la partie de matériau de filtre à fibre; une première partie de fixation de fibre qui est disposée au niveau d'une position inférieure de la partie cylindrique externe et qui fixe l'extrémité inférieure du matériau de filtre à fibre; une partie mobile dans le cylindre disposée à une position faisant face à la première partie de fixation de fibre dans la partie cylindrique externe, de façon à être mobile à l'intérieur de la partie cylindrique externe; et une seconde partie de fixation de fibre qui est disposée sur la partie mobile dans le cylindre et qui fixe l'extrémité supérieure de la partie de matériau de filtre à fibre, la partie mobile dans le cylindre étant sous une forme de bol, et l'évidement de la partie mobile dans le cylindre sous forme de bol étant disposé de façon à être tourné vers la première partie de fixation de fibre.
