Problems solved by technology

However, the air bubbles produced by triangular or multi-edged pores are larger than those produced by point-shaped micropores, which affects the aeration efficiency.
Moreover, if this type of hole is aerated for a long time, it is easy to tear, which reduces the life of the diaphragm

Embodiment Construction

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

[0018] Such as Figures 1 to 4 As shown, the present invention includes a support disc 1 and a membrane 2 covering the support disc. The support disc 1 is a circular curved disc body with a hollow center, and the inner ring and the outer ring are respectively provided with inner pressure grooves 3 and outer pressure grooves 4 with U-shaped cross-sections. An inner pressure ring 5 and an outer pressure ring 6 corresponding thereto are respectively provided in the inner and outer pressure grooves. The disc body of the support disc 1 is provided with two air intake holes 7, and can also be provided with a plurality of them as required. A support base 8 is connected to the lower end of each air inlet 7 and communicates with the support base. The supporting bases 8 communicate with each other through pipes, and communicate with the saddle frame 9 below th...

Abstract

The invention relates to a micropore aerator which comprises a support disc provided with an air inlet hole and a membrane covering the support disc, wherein the membrane is provided with micropores; the support disc is a circular curved disc body; an inner pressing groove and an outer pressing groove are respectively formed in the edges of an inner ring and an outer ring of the support disc, and an inner pressing ring and an outer pressing ring which are matched with the pressing grooves are respectively arranged on the edges of the inner ring and the outer ring of the support disc; the membrane is shaped as a circle adaptive to the support disc; the edges of the membrane are tightly pressed in the pressing grooves; a baffle plate which is integrally connected with the outer pressing ring is arranged on the outer pressing ring, so that air bubbles on the outmost periphery flow upwards along the baffle plate, so that the necking phenomenon caused by periphery radial water pressure is avoided. The micropore aerator disclosed by the invention is reasonable in design, simple in structure, convenient to use and high in aeration efficiency; the aeration membrane is long in life; the aerator is stable to support and is rapid to mount on the spot.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to an aerator, specifically a 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, and the Chinese patent "an improved diaphragm type microporous aerator" (notification number: CN23993838Y, announcement date October 4, 2010) will aerate The diaphragm and the supporting seat are changed into an annular arc-shaped surface with a penetrating water channel in the middle, and in order to reduce the aeration resistance, the micropores are changed into three-edged or multi-edged holes, thus balancing the pressure difference of the air bubble flow under the ac...
