Title:
STORAGE UNIT, STORAGE TANK USING SAME, AND STORAGE OSMOTIC TANK
Document Type and Number:
WIPO Patent Application WO/2011/129019
Kind Code:
A1
Abstract:
The inside of a storage tank is filled with a storage unit (11). A through hole (16a) is formed at the center of each of a plurality of quadrilateral division plates (12). On the upper and lower surfaces of each of the quadrilateral division plates (12), a plurality of cylindrical ribs are formed in a protruding manner concentrically with the through hole. A plurality of circular-truncated-shaped tubular spacers (13) are connected to either or both of the upper and lower surfaces of each of the quadrilateral division plates (12) in such a way as to fit over the outermost cylindrical ribs. A main shaft pipe (14) is inserted into the through hole in each of the quadrilateral division plates (12). Furthermore, a plurality of layers of horizontally connected bodies (33) are provided, each of said horizontally connected bodies (33) being formed by arranging a plurality of division plates side by side on the same horizontal plane and connecting said division plates to one another. Moreover, spacers are interposed between the plurality of layers of horizontally connected bodies, and a main shaft pipe is vertically inserted into the through hole in each of the division plates which constitute the plurality of layers of horizontally connected bodies. Members with relatively simple shapes, such as spacers, bottom plates, top plates, etc. are used, with the result that manufacturing costs of a storage tank and a storage osmotic tank are reduced, and that the manufacturing man-hours for dies for forming these members are decreased.
