To explain with reference to the drawings, the air diffuser of the present invention has a ventilation pipe 1 penetrating through the approximate center of a porous air diffuser plate 3, as shown in FIGS. 1 and 2. It is characterized in that the outer peripheral surface of the air plate 3 is covered with a seal cap 4 made of an elastic member such as rubber.

給管６を接続できるようにするのが好ましい。 The porous air diffuser plate 3 is a plate material in which a large number of pores are continuously formed in a three-dimensional mesh shape by sintering polymer powder such as polypropylene or polystyrene, and has a circular shape as shown in the figure. In plate shape,
Alternatively, it can be formed into a desired shape such as an ellipse or a rectangle. Moreover, instead of the sintered body of polymer powder, a sintered body of metal or ceramics may be used.
The ventilation pipe 1 is advantageously formed as a joint with a thread 1a carved on its outer periphery as shown, and one end of the ventilation pipe 1 is inserted through a mounting hole 3a provided in the center of the porous diffuser plate 3. It is preferable to fix it with a nut 2 so that the air supply pipe 6 can be connected to the other end.

In this case, it is desirable to provide the reinforcing ribs 5 in a radial or mesh-like manner in order to appropriately suppress pressure expansion during ventilation and strengthen the elastic return force.

As shown in FIG. 3, air from the air supply pipe 6 passes through the ventilation pipe 1 and is supplied between the porous diffuser plate 3 and the inner peripheral surface of the seal cap 4. The seal cap 4 expands due to the air pressure, and the supplied air is discharged to the outside through the pores of the porous diffuser plate 3, generating a large number of bubbles, which come into contact with waste water, etc., and dissolve oxygen in the water. encourage.

とができる。 Therefore, when the air blower stops due to power outage, switch operation, etc., the expanded seal cap 4 contracts while maintaining the balance between water pressure and its elastic return force, thereby pushing the internal air out. Therefore, it is possible to prevent water from flowing back into the interior of the porous diffuser plate 3, and to reliably prevent solid matter such as dust and filth from depositing in the pores of the porous diffuser plate 3 and causing clogging.

As described above, in the present invention, when air is sent out from the air supply pipe, the seal cap formed of an elastic member such as rubber expands, and air is generated between the porous diffuser plate and the seal cap. Air from this air chamber passes through the porous diffuser plate and is discharged into the water, so it is possible to generate a large number of bubbles with a simple structure of the porous diffuser plate and the seal cap, and when the ventilation is stopped. The expanded seal cap contracts while maintaining the balance between water pressure and its elastic return force, discharging the air in the air chamber to the outside, thereby preventing sewage from entering the porous diffuser plate.
This has the effect of preventing dust and dirt from entering the pores of the porous diffuser plate and causing clogging.
