Abstract

L'objectif de l'invention est d'offrir un réservoir à liquide comportant plusieurs cloisons. Le réservoir à liquide présenté, qui est constitué d'acier inoxydable ou d'un matériau duplex, est délimité par une paroi extérieure (140) et fermé au sommet par une paroi de sommet et au fond par une paroi de fond (170, 180). Plusieurs cloisons circulaires (110, 120, 130) sont disposées concentriquement à l'intérieur du réservoir pour former plusieurs chambres (118, 128, 138, 148) séparées. Lors du remplissage des chambres avec du liquide, le liquide s'écoule doucement de façon circonférentielle le long des cloisons. Le liquide s'écoule le long de tuyaux (201, 202, 203) inclinés, ce qui permet la dilution efficace de désinfectants ajoutés au liquide. Les parois extérieures sont produites sous la forme d'unités cylindriques pouvant faire l'objet d'une production en série, de sorte que le réservoir est d'une fabrication facile et simple et qu'il peut être installé en un temps court.
