Technical field
The utility model relates to technical field of sewage, and in particular to a kind of diaphragm type aerator.
Background technique
Diaphragm type aerator is also plate-type aerator, has aeration bubbles diameter small, gas-liquid interface diameter is small, gas-liquid interface
Product is big, and uniformly, the strong advantage of corrosion resistance is commonly to set current sewage treatment plant's two stage biological processing stage for bubble diffusion
It is standby, air blower by air by pipeline to aeration tank bottom, air is divided into minute bubbles to be diffused into dirt by the micropore on diaphragm
In water, so that aerobic microbiological absorbs the oxygen in bubble in sewage, and then sewage is handled, reduce the organic contamination in sewage
Object.But the effect of existing diaphragm type aerator diffused air into water body is not fine.
Utility model content
The technical problems to be solved in the utility model be overcome the deficiencies in the prior art and provide it is a kind of convenient for air to water
The diaphragm type aerator spread in body.
In order to solve the above technical problems, technical solution adopted in the utility model is:
A kind of diaphragm type aerator, aeration plate including spheric, be installed in aeration plate radially inside on air inlet pipe with
And cover the rubber diaphragm on aeration plate；The upper orifice of the air inlet pipe is connected with the air dispelling hole being opened at aeration disk center；
The edge of the top disk of the aeration plate offers circular air discharge duct, and offers in the top disk of aeration plate more
The air channel of item connection air dispelling hole and air discharge duct.
Further, the aeration plate and air inlet pipe are an integral structure.
Further, the air channel is opened up each along the major circle of a sphere of aeration plate.
Further, it is uniformly installed with a plurality of aeration plate reinforcing rib on the medial surface of the aeration plate and around air inlet pipe,
And aeration plate reinforcing rib is an integral structure with aeration plate and air inlet pipe.
Further, the aeration plate reinforcing rib is the arc of indent.
Further, it is installed with circular support tube at the inside edge of the aeration plate, and passes through spiral shell on support tube
Line is connected with the diaphragm gland of circular ring shape.
Further, multiple gland reinforcing ribs, and gland reinforcing rib are uniformly installed on the outer wall of the diaphragm gland
It is an integral structure with diaphragm gland.
The beneficial effects of adopting the technical scheme are that
The utility model is convenient for assembling and the diffused air into water body.Aeration plate is spheric, and surface and edge are very
It is smooth, it is convenient for rubber diaphragm from upper square set on aeration plate；Diaphragm gland is threadedly attached in support tube, convenient in rubber membrane
Piece screws after packaging upwards to push down diaphragm gland from below.The bottom end of air inlet pipe is provided with outer for what is be connected with steam line
Screw thread, air enter the air dispelling hole at aeration disk center through air inlet pipe, then the row of aeration plate top edge is passed through by air channel
In air drain, air is spread in the flow process in the disk of top, through rubber diaphragm into water body.

Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
It is aeration plate 2 including spheric, fixed as shown in Figure 1-3, the utility model discloses a kind of diaphragm type aerators
Aeration plate 2 radially inside on air inlet pipe 4 and cover the rubber diaphragm 5 on aeration plate 2；At the inside edge of aeration plate 2
It is installed with circular support tube 1, and is connected through a screw thread the diaphragm gland 3 of circular ring shape on support tube 1；Aeration plate 2 it is interior
A plurality of aeration plate reinforcing rib 8 is uniformly installed on side and around air inlet pipe 4.The upper orifice of air inlet pipe 4 and it is opened in aeration plate 2
Air dispelling hole at center is connected；The edge of the top disk of aeration plate 2 offers circular air discharge duct 7, and aeration plate 2
The air channel 6 of a plurality of connection air dispelling hole and air discharge duct 7 is offered in the disk of top, and air channel 6 is each along the ball of aeration plate 2
Face great circle opens up.
Aeration plate reinforcing rib 8 is the arc of indent, more preferable to the structural strength reinforcing effect of aeration plate 2 and air inlet pipe 4.By
Be circular ring shape in diaphragm gland 3, internal-and external diameter is larger, and length is smaller, to enhance its structural strength, diaphragm gland 3 it is outer
Multiple gland reinforcing ribs 9 are uniformly installed on wall.The aeration plate 2, air inlet pipe 4, support tube 1 and aeration plate of the utility model are reinforced
Muscle 8 is an integral structure, and gland reinforcing rib 9 is an integral structure with diaphragm gland 3.
The utility model is convenient for assembling and the diffused air into water body.Aeration plate 2 is spheric, and surface and edge are very
It is smooth, it is convenient for rubber diaphragm 5 from upper square set on aeration plate 2；Diaphragm gland 3 is threadedly attached in support tube 1, convenient in rubber
Glue film 5 screws after packaging upwards to push down diaphragm gland 3 from below.The bottom end of air inlet pipe 4, which is provided with, to be used for and steam line
Connected external screw thread, air enters the air dispelling hole at 2 center of aeration plate through air inlet pipe 4, then is passed through aeration plate 2 by air channel 6 and pushes up
In the air discharge duct 7 of portion edge, air is spread through rubber diaphragm 5 into water body in the flow process in the disk of top.
