DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Referring to Figures 1-7 The micro-porous aerator with multi-layer filtration provided in the embodiment comprises a support body 1, the top of the support body 1 is provided with an aerator disc 3 through an end cover 2, the inside of the support body 1 is provided with at least two filter screens 4, and the inside of the support body 1 is provided with a cleaning mechanism 5 for preventing blockage on the surface of the filter screen 4 through compressed air, the cleaning mechanism 5 comprises a connecting shaft 52 rotatably installed in the inside of the support body 1 through a bracket assembly 51, the bracket assembly 51 comprises fixed rods 511 arranged in a cross shape, the center position of the fixed rod 511 is provided with a bearing seat 512 matched with the connecting shaft 52, the bottom of the connecting shaft 52 is provided with a wind turbine 53, the connecting shaft 52 is provided with a dust removal assembly 54, the end cover 2 is detachably connected with the support body 1 through a flange 6, and the bottom of the support body 1 is provided with an air inlet through a conical cylinder.

[0025] In this invention, the vent on the conical cylinder at the bottom of the support body 1 is connected to a blower or compressed air pipe. During use, compressed air enters the support body 1 through the vent and is then filtered by the filter screen 4 inside the support body 1 to remove impurities from the air. The filtered air flows out through the aeration disc 3 on the end cover 2. The aeration disc 3 disperses air or oxygen into the wastewater in the form of tiny bubbles through a microporous structure, increasing the dissolved oxygen content in the wastewater. When compressed air enters the support body 1, it drives the wind turbine 53 to rotate under the action of airflow. The wind turbine 53 is connected to the bottom of the connecting shaft 52 of the support assembly 51. The connecting shaft 52 passes through the bearing seat 512 in the middle of the fixed rod 511, so that the wind turbine 53 can drive the connecting shaft 52 on the support assembly 51 to rotate, thereby causing the dust removal component 54 on the connecting shaft 52 to rotate and clean the filter screen 4. The surface of the filter screen 4 can be cleaned in real time to keep it unobstructed, thereby ensuring that the aerator can continuously and stably provide oxygen and greatly improve the aeration efficiency.

[0026] It should be noted that there are at least two filters 4, which enables multi-layer filtration. Filter 4 can be a metal filter or an activated carbon filter to ensure that particulate impurities in the air are filtered out, thereby preventing the micropores on the aeration disc 3 from becoming clogged.

[0027] Specifically, such as Figures 3-5 As shown, the dust removal assembly 54 includes a fixed seat 541 sleeved on the connecting shaft 52. A brush 543 is provided on the fixed seat 541 via a connecting rod 542, which abuts against the surface of the filter screen 4. The fixed seat 541 is provided with a mounting sleeve 544 that mates with the end of the connecting rod 542. The mounting sleeve 544 is provided with a mounting bolt 545, and the connecting rod 542 is provided with a mounting screw hole 546 that mates with the mounting bolt 545.

[0028] The brush 543 on the connecting rod 542 abuts against the filter screen 4. When the wind turbine 53 drives the connecting shaft 52 to rotate, the connecting rod 542 on the fixed base 541 rotates with the connecting shaft 52. Then, the brush 543 on the connecting rod 542 cleans the surface of the filter screen 4 during the rotation, thereby cleaning the surface of the filter screen 4 and keeping it unobstructed. This ensures that the aerator can continuously and stably provide oxygen, greatly improving the aeration efficiency. When the brush 543 needs to be disassembled and replaced, the mounting bolt 545 on the mounting sleeve 544 is unscrewed, so that the mounting bolt 545 is disengaged from the mounting screw hole 546 of the connecting rod 542. This allows the connecting rod 542 to be pulled out of the mounting sleeve 544, thus disassembling the brush 543.

[0029] Specifically, such as Figure 4 and Figure 6As shown, a limiting plate 521 is provided on the connecting shaft 52 to abut against the top of the wind turbine 53, and a limiting nut 523 is provided at one end of the connecting shaft 52 through a threaded end 522 to abut against the bottom of the wind turbine 53.

[0030] The bottom of the connecting shaft 52 passes through the wind turbine 53. After the limit nut 523 is tightened on the threaded end 522 of the connecting shaft 52, the limit nut 523 and the limit plate 521 clamp and fix the wind turbine 53, thereby realizing the installation and fixation of the wind turbine 53 on the connecting shaft 52. When the wind turbine 53 needs to be disassembled and repaired, the limit nut 523 can be removed, and then the wind turbine 53 can be pulled out from the connecting shaft 52, which facilitates the disassembly and assembly of the wind turbine 53, and thus facilitates the maintenance and repair of the wind turbine 53.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
