Abstract

Brassage mécanique et aération forcée simultanés de boues de station d'épuration.L'invention concerne un dispositif automatique de brassage et d'aération d'un lit de boues déshydratées dans une aire de stockage.Il est constitué d'un pont roulant (1) supportant un chariot (2).Sont embarqués sur le chariot un ou plusieurs appareils de brassage et un compresseur d'air comprimé (6).Chaque appareil de brassage comprend 1 moteur (3), 1 arbre vertical (4) sur lequel sont fixées une vis (4) et des fraises (5), type motoculture.Le dispositif est principalement prévu pour brasser et aérer des boues de station d'épuration d'origine urbaines et/ou industrielles.

Description

La présente invention concerne un dispositif de retournement, de brassage
et
d'aération forcée de boues d'unité de traitement des eaux usées urbaines ou industrielles.
Ce dispositif est principalement utilisé pour retourner et aérer des boues déshydratées (siccité minimale de 15 %) stockées dans une aire de stockage spécifique.
Le dispositif comporte un pont roulant (1) permettant un déplacement longitudinal supportant un chariot (2) se déplaçant transversalement, de manière à couvrir l'ensemble de l'aire de stockage.
Le chariot (2) supporte deux appareils de retournement comportant chacun un motoréducteur ou un motovariateur (3), une vis verticale à arbre creux, équipé ou non de 10 fraises, type motoculture (5) Un compresseur air comprimé (6) insuffle de l'air par l'intermédiaire de l'arbre creux (4) de transmission en partie basse du lit de boues, afin de maintenir celles- ci en milieu aérobie. L'air est distribuée par des ouïes orientées en opposition du sens de rotation de l'arbre.
Le plan de principe annexé (plans n'1 et n02) illustre l'invention.
L'invention est principalement dédiée au retournement, au brassage et à l'aération de boues d'unité de traitement des eaux usées urbaines ou industrielles stockées dans une serre pour séchage. En outre, il permet de remonter la boue et de casser les éventuelles mottes.
