A plurality of air holes are arranged outside the aeration disk, and the air holes on each aeration disk are arranged staggeredly. A plurality of protrusions are arranged on both sides of the aeration disk, and the positions of the convex teeth are staggered, so that when the aeration disk reciprocates, the convex teeth can reciprocate to play a role in disturbing the flow, and at the same time, the protrusions can cooperate with the convex teeth to disturb the water flow. Secondly, the air holes are arranged staggeredly, so that the water flow can flow staggeredly, thereby facilitating the subsequent aeration effect". However, in the prior art, the convex teeth and air holes on the surface of the aeration disk are easily attached and blocked by impurities in the sewage, resulting in low aeration efficiency.

[0018] Referring to Figures 1 to 4 As shown in the figure, the utility model provides an environment-friendly sewage aeration and oxygenation rotary disk device, which comprises an aerator seat 1 and an aeration rotary disk 2. The side end of the aerator seat 1 is connected with the aeration rotary disk 2 through a transmission shaft 11.

[0019] A dredging brush plate 4 is distributed on the left side surface of the aeration rotary disk 2. A cleaning cross plate 3 is screwed to the upper end of the dredging brush plate 4. Hydraulic cylinders 31 are connected to the left and right sides of the cleaning cross plate 3. A cross rubber push block 41 is fixed to the right side surface of the cleaning cross plate 3 through a fixing plate 42. The cross rubber push block 41 is inserted into the aeration holes 22 on the disk surface of the aeration rotary disk 2. The left side surface of the dredging brush plate 4 is in contact with the disk surface of the aeration rotary disk 2 through bristles 43.

[0020] During use, when the vertical outdoor motor 12 normally drives the aeration rotary disk 2 on the surface of the transmission shaft 11 to rotate, bubbles are generated in the holes when the aeration rotary disk 2 rotates in the sewage, and the bubbles bring oxygen into the sewage to achieve the oxygenation effect. Set the regular pushing time of the hydraulic cylinder 31. When the hydraulic cylinder 31 pushes the cleaning cross plate 3 to the left, the bristles 43 of the dredging brush plate 4 are in contact with the disk surface of the aeration rotary disk 2 to brush off the surface impurities. At the same time, the cross rubber push block 41 is inserted into the aeration holes 22 on the disk surface of the aeration rotary disk 2 to push out the impurities in the aeration holes 22 to the left. After cleaning, the hydraulic cylinder 31 resets and the cleaning cross plate 3 moves to the right, so that the dredging brush plate 4 is not in contact with the aeration rotary disk 2, and the cleaned aeration rotary disk 2 continues to aerate and oxygenate the sewage.

[0021] In this embodiment, the transmission shaft 11 is connected to the aerator seat 1 on both the left and right sides; and a vertical outdoor motor 12 is installed on the upper surface of the right aerator seat 1, and the vertical outdoor motor 12 is connected to the transmission shaft 11 through a transmission mechanism.

[0022] As a preferred implementation mode, the vertical outdoor motor 12 is used as the power source for the rotation of the aeration rotary disk 2, which is convenient for controlling the rotation speed of the aeration rotary disk 2.

[0023] In this embodiment, a central hole 23 is opened in the middle of the aeration rotary disk 2. Shaft connectors 24 are welded to the left and right sides of the central hole 23; and the transmission shaft 11 passes through the central hole 23. Aeration holes 22 are arranged at the outer end of the central hole 23, and the aeration holes 22 are distributed in a ring shape; and the aeration holes 22 are narrow in the middle and wide at both ends.

[0024] As a preferred implementation mode, multiple groups of aeration rotary disks 2 are installed on the surface of the transmission shaft 11, so that one transmission shaft 11 drives multiple groups of aeration rotary disks 2 to rotate. The aeration holes 22 are narrow in the middle and wide at both ends, which is convenient for moving the blocked impurities to the wider parts at both ends, so as to discharge the blocked impurities.

[0025] In this embodiment, paddle boards 21 are welded equidistantly on the outer ring surface of the aeration rotary disk 2. A support frame 33 is fixedly screwed to the upper end surface of the aerator seat 1, and a hydraulic cylinder 31 is fixedly embedded inside the support frame 33. The lower end of the cleaning cross plate 3 is fixedly screwed to the dredging brush plate 4 through a fastening bolt 32, and the cross rubber push blocks 41 correspond to the distribution positions of the aeration holes 22.

[0026] As a preferred implementation, the paddle boards 21 facilitate the aeration rotary disk 2 to better push the sewage, disturbing the sewage to generate more bubbles and enhancing the oxygenation amount of the aeration rotary disk 2. As the aeration rotary disk 2 rotates, the cross rubber push blocks 41 move in and out of the holes. When the cross rubber push blocks 41 enter the aeration rotary disk 2, the cross heads of the cross rubber push blocks 41 push the blocked impurities in the holes to the other side, enabling the impurities to enter the wider aperture through the narrower aperture in the middle and then be discharged from the wider aperture end, thus achieving the dredging effect.

[0027] In this embodiment, the cleaning cross plate 3, the hydraulic cylinder 31, the dredging brush plate 4, and the cross rubber push blocks 41 constitute the cleaning mechanism of the aeration rotary disk 2.

[0028] As a preferred implementation, the cleaning mechanism of the aeration rotary disk 2 facilitates the cleaning and dredging of the impurities attached to and blocked in the aeration rotary disk 2, enabling the aeration and oxygenation rotary disk device to conveniently maintain the maximization of the generated bubble volume, enhancing the oxygen content in the sewage, improving the aeration and oxygenation efficiency, reducing the rotation duration, and saving energy consumption.

[0029] The environment-friendly sewage aeration and oxygenation rotary disk device of the present utility model can effectively solve the problem in the prior art that the convex teeth and aeration holes on the surface of the aeration disk are prone to attaching and blocking impurities in the sewage, resulting in low aeration efficiency. It facilitates the cleaning and dredging of the impurities attached to and blocked in the aeration rotary disk, enables the aeration and oxygenation rotary disk device to conveniently maintain the maximization of the generated bubble volume, enhances the oxygen content in the sewage, improves the aeration and oxygenation efficiency, reduces the rotation duration, and saves energy consumption, and is applicable to the environment-friendly sewage aeration and oxygenation rotary disk device.
