Plastic container

摘要

The plastic container for water treatment plant, has external walls (11), base area (12), head area (13), opening for clarifiers, arranged in the head area, and a primary clarifier (2), a main clarifier (3), a secondary clarifier (4), which are separated each other by three partitions. The partitions are formed by sharp bulging from the base area to the head area, and the container is manufactured as single piece in rotational forms. A rotary bulge projecting outwardly, is formed in the transition between the base area and the external walls. The plastic container for water treatment plant, has external walls, base area, head area, opening for clarifiers, arranged in the head area, and a primary clarifier, a main clarifier, a secondary clarifier separated each other by three partitions. The partitions are formed by sharp bulging from the base area to the head area, and the container is manufactured as single piece in rotational forms. A rotary bulge projecting outwardly, is formed in the transition between the base area and the external walls. The external walls of the base area stand easily in an inclined angle of 1-5 degree and exhibits flanges. The base area exhibits flat-uniform surface sections, which lie with an intended position of the container on a lowest horizontal level. A man opening with a removable cover is assigned in the head area and exhibits a cylindrical cathedral section, and a circle-disk-shaped cover sealing is insertable in an upper edge of the cylindrical cathedral section. The clarifiers are arranged around a center, which forms a vertically oriented passage opening, which shows a frustum of cone form. The plastic container has a quadratic outline and has a width of smaller than or equal to 2.34 m and height of smaller than or equal to 2.29 m. The primary clarifier takes the main clarifier of a quadrant and the secondary clarifier of the final quadrant of the outline. The external walls, the partitions, the head area and the base area have a thickness of 8-15 mm. Crane eyes are arranged at the head area and lie diametrically opposite to each other. Mounting surfaces are intended for mounting of inlet and drain at the external wall in the area of the primary clarifier and in the area of the secondary clarifier near to the head area.
