PURPOSE:To detachably laminate a treatment cylindrical cartridge by a vertically moving mechanism of an upper cylinder and to make replacement work easy and to simplify a structure by constituting a purification treatment cylinder of a split structure and providing the vertically moving mechanism for vertically moving the upper cylinder. CONSTITUTION:A purification treatment cylinder 5 is provided by equipping a first and second supply-discharge ports 6a, 6b to the upper and lower end parts and packing the purification treatment material (e.g. activated carbon) to the inside. Purification treatment is performed by passing liquid through the purification treatment substance packed in the cylinder 5. This cylinder 5 is constituted of a split structure which consists of a bottom cylinder 7 having the first supply-discharge port 6a, the treatment cylindrical cartridges 8a-8d successively laminated on the bottom cylinder 7 and packed with the purification treatment material to the insides thereof and the upper cylinder 9 provided on the uppermost-step cartridge 8d and equipped with the second supply- discharge port 6b. The upper cylinder 9 is vertically moved by a vertically moving mechanism 10. The treatment cylindrical cartridges are detachably laminated by this mechanism 10. Replacement work is made easy and the structure is simplified. |
