Abstract
The utility model relates to a microporous aerator which comprises an aerator base plate, an air distributing disk, and a sealing ring, wherein, the lower part of the aerator base plate is provided with an air inlet; a plurality of lopsided flanges are uniformly arranged on the circumference on the outer side of the aerator base plate; the air distributing disk is arranged in the aerator base plate; a pressing cover presses against the air distributing disk through the sealing ring to be connected with the aerator base plate; the aerator base plate and the air distributing disk adopt a pressure cooker type sealing mode. The utility model has the advantages of simple structure and favorable sealing performance. The air distributing disk adopts super molecule polyethylene material and uniformly and richly contains meshed branch-shaped micropores, the pore diameter is small, the porosity is high, the aeration area is large, the oxygen transfer efficiency is high, the surface is smooth, dirt is not easy to settle, the blockage is reduced, and break is not easy to happen.
Description
The utility model relates to the biochemical treatment apparatus of a kind of waters waste water or sewage, especially a kind of waters micro-hole aerator.
In the method for disposing of sewage, biochemical treatment is a kind of efficient ways, and promptly economy is easy again, in order to improve its treatment effect, in sewage to be processed, sufficient dissolved oxygen need be arranged, to promote the oxidizing reaction in the sewage.Aerator is the main device of oxygen supply in sewage.At present the disc type aerator that uses as shown in Figure 5, aerator chassis 51 is connected with the bolt 53 of air-spreading disk 52 by the center of being located at, on the aerator chassis 51 and air-spreading disk 52 junctions be provided with gasket 54.Because air-spreading disk 52 usefulness potteries are made, broken easily during use, and weight is big, the coarse easy deposit dirt of ceramic surface.Heart position connects with bolt therein, makes aerator periphery position stopping property poor, easily gas leakage.
The utility model is the shortcoming that overcomes above-mentioned aerating apparatus, provides a kind of simple in structure, long service life, the micro-hole aerator of good seal performance.
The utility model micro-hole aerator comprises the aerator chassis, air-spreading disk and sealing-ring, wherein on the outer circumference of described aerator chassis, evenly be provided with the flange of several lopsidedness, the air-spreading disk that is become by ultrahigh molecular weight polyethylene places the aerator chassis, the internal diameter on its bottom external diameter and aerator chassis is corresponding, the inside circumference of gland is provided with and the corresponding boss of aerator chassis flange, flange and boss are cross-linked up and down after the gland rotation, are provided with sealing-ring between described gland and air-spreading disk and the aerator chassis.
Another improvements of the present utility model are that the outer circumference wall of gland is provided with several axial projections.
An improvement part more of the present utility model is that aerator chassis and gland are made of plastics.
Advantage of the present utility model and positively effect are that the outside of aerator chassis and air-spreading disk and inboard are respectively equipped with flange and boss, after both fasten, are cross-linked up and down through rotation, and adopt the sealing of pressure cooking-pot type, and be simple in structure, good seal performance; Air-spreading disk adopts superhigh molecular weight polyethylene material, evenly is rich in netted branch shape micropore, and the aperture is little, the porosity height, and stress distribution is even, oxygen transmission efficiency height, and its smooth surface are difficult for stagnant dirt, reduce and stop up, be difficult for fragmentation, in light weight, corrosion-resistant, the life-span is long.

Other details of the present utility model and characteristics can be cheer and bright by reading the embodiment that encyclopaedizes below in conjunction with accompanying drawing.
Shown in Fig. 1-4, the utility model micro-hole aerator comprises aerator chassis 1, air-spreading disk 4 and sealing-ring 2, wherein on 1 outer circumference of described aerator chassis, evenly be provided with the flange 5 of several lopsidedness, the air-spreading disk 4 that is become by ultrahigh molecular weight polyethylene places aerator chassis 1, the internal diameter on its bottom external diameter and aerator chassis is corresponding, the inside circumference of gland 3 is provided with the flange 5 corresponding boss (not drawing among the figure) with aerator chassis 1, flange 5 and boss are cross-linked up and down after gland 3 rotations, and the inclined-plane of flange 5 can make it closely be connected with boss.Be provided with sealing-ring 2 between described gland 3 and air-spreading disk 4 and the aerator chassis 1.Aerator chassis 1 and gland 3 are made of plastics.
The outer circumference wall of gland 3 is provided with several axial projections, can tighten with instrument when being used for being connected with aerator chassis 1.
During micro-hole aerator work, the inlet mouth of its 1 bottom, aerator chassis is connected with aeration tube, aerator is placed the bottom, aeration tank, there is the air of pressure to enter in the cavity of aerator by aeration tube, air oozes out from polyethylene air-spreading disk 4 surfaces, in water, can produce the microbubble of diameter≤3mm, thereby reach oxygen transmission efficiently.
Claims (3)
1, a kind of micro-hole aerator, comprise the aerator chassis, air-spreading disk and sealing-ring, it is characterized in that evenly being provided with on the outer circumference of described aerator chassis the flange of several lopsidedness, the air-spreading disk that is become by ultrahigh molecular weight polyethylene places the aerator chassis, the internal diameter on its bottom external diameter and aerator chassis is corresponding, the inside circumference of gland is provided with and the corresponding boss of aerator chassis flange, flange and boss are cross-linked up and down after the gland rotation, are provided with sealing-ring between described gland and air-spreading disk and the aerator chassis.
