Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 and 2 As shown, the present invention includes a support plate 1 and a diaphragm 2 covering the support plate, wherein the support plate 1 is a circular curved disc with a hollowed out center, and the hollowed out center can allow water flow to form a through water channel. An annular gas distribution groove 10 is provided on the bottom surface of the support plate 1 to transmit the gas input from the outside. The air distribution groove 10 is concentric with the support plate 1 and has the same distance from the inner and outer edges of the support plate 1 . A plurality of gas distribution holes 11 communicating with the gas distribution groove 10 is provided on the support plate 1, and the input gas can be output through these gas distribution holes. The gas distribution holes 11 can be evenly distributed on the gas distribu...

Abstract

The invention relates to a hollow disk-type fine bubble aerator, which comprises a support disk and a diaphragm covering the support disk, wherein the support disk is a circular cambered disk body being hollow in the center; the diaphragm is provided with micropores, and is fixed to the support disk through a compacting structure; an annular air distribution groove and a plurality of air distribution holes communicated with the air distribution groove are formed in the middle of the support disk; an air inlet hole is formed in the bottom surface of the air distribution groove, and is communicated with a supporting seat arranged below the support disk; the supporting seat is deviated from one side of the support disk, and is prevented from shielding a through water channel in the central hollow position of the support disk. The improved hollow disk-type fine bubble aerator is reasonable in structure, and convenient to use. The supporting seat is deviated from the through water channel in the center of the support disk, so that the propelling action of the through water channel on bubble is ensured, the phenomenon of bubble necking or bubble combination is avoided, and the aeration efficiency is improved remarkably.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to an aerator, in particular to a hollow disc microporous aerator. Background technique [0002] At present, under the action of water pressure, the micro-bubble flow produced by the commonly used disc aerator will constrict radially, which will reduce the area of ​​bubble diffusion and make the bubbles gather into larger bubbles, thereby reducing the Aeration efficiency. For this reason, people improve the diaphragm type disc aerator. The Chinese patent "an improved diaphragm type microporous aerator" (notification number: CN2399383Y, announcement date: 2000.10.4) combines the aeration diaphragm and The support seat is changed to an annular arc-shaped surface with a penetrating water channel in the middle, and in order to reduce the aeration resistance, reduce the radial necking caused by the water pressure during the upward flow of the bubbles, reduce the accumulation of bubbles, and ...
