Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.

The embodiment of the utility model comprises the following steps:

as shown in fig. 1 to 3, an aeration apparatus having a sludge cleaning function includes an aeration head 1 and a connection pipe 2.

The aeration head 1 is the same as that of the traditional aeration device, the upper end surface and the lower end surface are arc surfaces, and a plurality of aeration holes 10 are arranged on the arc surface at the upper part and used for flowing air into a sewage pool; the upper end of the connecting pipe 2 is fixedly arranged on the arc-shaped surface of the lower part of the aeration head 1 and is communicated with the aeration holes 10 in the aeration head 1.

Connecting pipe 2 is the column, overlaps on its periphery wall to be equipped with a swivel becket 3, and swivel becket 3 can rotate under the exogenic action, is equipped with support frame 31 on the swivel becket 3, and support frame 31 is the connecting rod form, is equipped with the brush hair on support frame 31, when rotating bad and carrying out the pivoted under the exogenic action, can drive support frame 31 and rotate, and then drive the brush hair on the support frame 31 and scrub aeration head 1's lower part and upper portion.

An annular air chamber 4 is also arranged on the outer wall of the connecting pipe 2, the air chamber 4 is communicated with the inside of the connecting pipe 2, namely, corresponding air pressure also exists in the air chamber 4 during aeration; four airflow holes 40 are uniformly arranged on the circumferential surface of the air chamber 4 at intervals, and when aeration is carried out, airflow in the air chamber 4 can be sprayed to the outside through the airflow holes 40; set up baffle 30 on swivel becket 3, baffle 30 is located the lower part of swivel becket 3, and is located the edge of air chamber 4 periphery simultaneously, and when the air current in air chamber 4 outwards sprayed in the air current hole 40, the air current promoted baffle 30 and rotates, and the rotation of baffle 30 drives swivel becket 3 and rotates to drive swivel becket 3 and rotate, support frame 31 in swivel becket 3 will drive the brush hair and rotate, thereby with aeration head 1 go up adnexed mud brush down.

In the present embodiment, the rotating ring 3 and the connecting pipe 2 are realized by the annular groove 21 and the annular rib 32, the outer peripheral wall of the connecting pipe 2 is provided with an annular step 20, and the annular groove 21 is arranged in the annular step 20; the annular convex strip 32 is arranged on the annular surface relatively close to the inner side in the rotating ring 3, the annular convex strip 32 is matched with the annular groove 21, and under the action of the air chamber 4 and the baffle 30, the annular convex strip 32 and the annular groove 21 move relatively to realize the rotation of the rotating ring 3.
