As shown in fig. 1 to 3, an embodiment of the present application provides an aeration apparatus including an aeration member 100, a first connection pipe 200, and a second connection pipe 400.

The aeration member 100 is provided with aeration holes 101, and the shape of the aeration holes 101 may be circular, oval, polygonal, or a combination of the above shapes, which is not limited in the embodiments of the present application. The aeration holes 101 may be distributed in an annular array on the aeration member 100. The aeration member 100 may include an aeration tube 110, and the shape of the aeration tube 110 may be cylindrical. The aeration pipe 110 has a first section and a second section connected to each other, and the first section and the second section may be integrally disposed or separately disposed, which is not limited in the embodiments of the present application.

The first connecting pipe 200 is provided with a pushing member 300 for bearing the thrust of the aeration air flow, the pushing member 300 is slidably connected with the first connecting pipe 200 and connected with the first section, and the pushing member 300 can be movably connected with the first section or fixedly connected with the first section. The first segment is at least partially located within the first connecting tube 200 and is movably connected to the first connecting tube 200.

The second connection pipe 400 is provided therein with an elastic member 500, and the elastic member 500 may be a spring. One end of the elastic member 500 is connected to the second connection pipe 400, and the other end of the elastic member 500 is connected to a second section, which is at least partially located in the second connection pipe 400 and is movably connected to the second connection pipe 400.

One of the second connection pipe 400 and the aeration pipe 110 is provided with a spiral guide groove 401, and the other one is provided with a matching protrusion 111, and the aeration pipe 110 can move and rotate along with the matching of the spiral guide groove 401 and the matching protrusion 111 to switch the aeration holes 101 between towards the bottom of the tank and towards the top of the tank.

A first fixing sleeve 700 is arranged at one end of the first connecting pipe 200 far away from the aeration pipe 110, and the first fixing sleeve 700 can be used for connecting the first connecting pipe 200 with other pipelines; the end of the second connection pipe 400 far from the aeration pipe 110 is provided with a second fixing sleeve 800, and the second fixing sleeve 800 can be used for connecting the second connection pipe 400 with other pipelines, so that the aeration air flow can continuously flow in the pipelines. Optionally, a first internal thread 701 for connecting with an external thread on another pipe may be provided in the first harness 700, and a second internal thread 801 for connecting with an external thread on another pipe may be provided in the second harness 800.

In the embodiment of the present application, when the aeration air flow is not introduced into the aeration apparatus, the aeration hole 101 faces the bottom of the aeration tank, when the aeration air flow is introduced into the first connection pipe 200, the pushing member 300 is pushed by the aeration air flow to slide toward the second connection pipe 400, and at the same time, the pushing member 300 pushes the aeration pipe 110 to move toward the second connection pipe 400 and rotate, so that the aeration hole 101 can be switched from facing the bottom of the tank to facing the top of the tank, and the aeration tank is continuously aerated and supplied with oxygen, and at the same time, the elastic member 500 disposed in the second connection pipe 400 is compressed, and thus elastic potential energy is accumulated; after the aeration airflow is disconnected, the thrust of the aeration airflow to the pushing piece 300 disappears, the elastic potential energy accumulated by the elastic piece 500 starts to be released, the released elastic potential energy pushes the aeration pipe 110 to move and rotate towards the first connecting pipe 200, and meanwhile, the aeration holes 101 can be switched from the direction towards the top of the tank to the direction towards the bottom of the tank so as to prevent sludge impurities settled in the aeration tank from settling into the aeration holes 101 to cause blockage of the aeration holes 101, and further, the aeration oxygen supply effect of the aeration device can be improved.

In an alternative embodiment, the pushing member 300 is a strip, and two ends of the strip are respectively connected to the inner wall surface of the first connecting pipe 200. When the aeration air current lets in first connecting pipe 200, because the blocking of strip spare for the aeration air current the condition of reposition of redundant personnel and confluence appears, thereby influence the flow of aeration air current easily. Therefore, in another alternative embodiment, the pushing member 300 is a ring-shaped member, and the circumferential surface of the pushing member 300 is connected to the inner wall surface of the first connecting pipe 200. In this embodiment, when the aeration air flows into the first connection pipe 200, since the push member 300 is an annular member, the aeration air flows can smoothly flow through the holes of the annular member, and the flow separation and flow combination do not occur due to the blocking of the push member 300.

In a further alternative embodiment, the inner diameter of the pushing member 300 is equal to the inner diameter of the aeration tube 110, in which case, the force-bearing area of the pushing member 300 is too small, so that the aeration tube 110 can be pushed to move and rotate only by the aeration air flow with a fast flow rate. Therefore, in an alternative embodiment, the inner diameter of the pushing member 300 is smaller than the inner diameter of the aeration tube 110. In this case, the pushing member 300 may have a larger force-bearing area, and the aeration air flow may push the aeration tube 110 to move and rotate without a fast flow rate, which is more advantageous for the aeration air flow to push the aeration tube 110 to move and rotate.

In one embodiment, the pushing member 300 is provided with a through hole, and the axis of the through hole is not collinear with the axis of the first connecting pipe 200, that is, the force-bearing area of a part of the pushing member 300 is large, and the force-bearing area of a part of the pushing member 300 is small, so that when the thrust of the aeration air flow acts on the pushing member 300, the acting force exerted on the pushing member 300 is not uniform, thereby preventing the aeration pipe 110 from moving and rotating smoothly. Therefore, in another embodiment, the axis of the through hole is collinear with the axis of the first connecting tube 200. In this case, the force-bearing area of any region of the pushing member 300 is the same, so the force exerted by the aeration air flow on the pushing member 300 is more uniform, and the pushing member 300 can move and rotate the aeration tube 110 more smoothly.

In an alternative embodiment, the inner wall surface of the second connection pipe 400 is provided with a plurality of limiting protrusions, the limiting protrusions are arranged at intervals along the circumferential direction of the second connection pipe 400, and one end of the elastic member 500 is connected with one surface of the limiting protrusion facing the elastic member 500. In this embodiment, the contact area between the spacing protrusions arranged at intervals and the elastic member 500 is small, and therefore, the reliability is poor. Therefore, in another alternative embodiment, the second connecting tube 400 is provided with a first position-limiting portion 402, the first position-limiting portion 402 is an annular structure, and one end of the elastic member 500 is connected to a surface of the annular structure facing the elastic member 500. In this embodiment, the elastic element 500 and the first position-limiting portion 402 can have a larger contact area, and therefore, the first position-limiting portion 402 can better limit the elastic element 500, thereby improving the reliability of the limiting.

In order to allow the aeration tube 110 to move and rotate with respect to the first connection tube 200, a gap is left between the aeration tube 110 and the first connection tube 200, and if the gap is not sealed, the aeration air flow leaks from the gap, which is not favorable for the aeration air flow to push the aeration tube 110 to move and rotate. Therefore, in an alternative embodiment, the aeration apparatus may further include a sealing member 600, the sealing member 600 is located between the aeration tube 110 and the push member 300, and the sealing member 600 seals a gap between the first connection tube 200 and the aeration tube 110. Sealing the gap by the sealing member 600 prevents the aeration air flow from leaking from the gap, thereby ensuring that the thrust generated by the aeration air flow is more effectively applied to the pusher 300.

In order to make the aeration holes 101 always face the top of the tank during aeration, in an alternative embodiment, when the aeration holes 101 face the top of the tank, a balance is achieved between the thrust generated by the aeration air flow and the elastic force generated when the elastic member 500 is compressed. However, in order to keep the thrust force and the elastic force in a balanced state, it is necessary to keep the flow rate of the aeration air flow constant, but such a control method is difficult. Therefore, in another alternative embodiment, the outer surface of the aeration pipe 110 is provided with a second limiting part and a third limiting part; the second limit part is contacted with the first connecting pipe 200 under the condition that the aeration holes 101 face the bottom of the tank; when the aeration hole 101 is directed to the top of the tank, the third stopper is in contact with the second connection pipe 400. In this way, when the second limiting part contacts the first connecting pipe 200, the aeration holes 101 face the bottom of the tank, and even if the elastic potential energy of the elastic member 500 is not released, the orientation of the aeration holes 101 is not changed due to the limitation of the second limiting part and always faces the bottom of the tank; when the third position-limiting portion contacts the second connection pipe 400, even if the velocity of the aeration air flow is too high, the aeration pipe 110 cannot be moved and rotated by the thrust generated by the aeration air flow, and the aeration holes 101 always face the tank top. It is clear that it is easier to control the orientation of the aeration holes 101 by the second and third position-limiting portions.

In one embodiment, the aeration holes 101 are formed in the aeration pipe 110, and since the aeration holes 101 are required to be formed in a large number and distributed, it is not advantageous to form the spiral guide grooves 401 or the engaging protrusions 111 in the aeration pipe 110. Therefore, the aeration member 100 may further include an aeration head 120, the aeration head 120 is communicated with the aeration pipe 110, and the aeration head 120 is provided with aeration holes 101. In this way, the aeration hole 101 can be prevented from affecting the arrangement of the spiral guide groove 401 or the fitting projection 111.

The embodiment of the application also discloses an aeration tank, which comprises the aeration device in any embodiment.

The embodiment of the application also discloses a sewage treatment system, which comprises the aeration tank in the embodiment.
