Document Type and Number:
Japanese Patent JP2665629
Kind Code:
B2
Abstract:
PURPOSE:To allow the continuous generation of fine bubbles even if the quantity of the air flowing out of an air chamber to a stored water side is throttled by providing plural sheets of main vanes between an upper horizontal partition plate and a lower horizontal partition plate. CONSTITUTION:The stored water of a fish raising pond P, etc., enclosed by the upper horizontal partition plate 10, the lower horizontal partition plate 11 and the respective mainvanes 12 moves in the outside circumferential direction of a vane wheel 13B when the vane wheel 13B is rotated on starting of a submersible motor 2. The small bubbles ejected from injection holes 15... are stirred and finely segmented by the rotation of the vane wheel 13B and are mixed in the form of fine particles with the stored water. A large quantity of oxygen is thus rapidly dissolved into the stored water. In succession, the stored water in which the air is made to coexist moves to the outer peripheral part of the vane wheel 13B and collides against the bubble breaking vanes 16... to further finely segment the bubbles, by which the dissolution effect of the oxygen in the air incorporated into the stored water is accelerated. The stored water delivered to the outer periphery of the vane wheel 13B is expanded into the water mass in the fish raising pond B by flow regulating plates 17... and the aeration effect over a wide range is progressed.
