Technical Field

[0001] The utility model relates to the technical field of aerators, and particularly to an aerator with adjustable depth. Background Art

[0002] An aerator injects microbubbles directly into untreated sewage through a diffuser impeller. Under the combined action of a coagulant and a flocculant, suspended solids undergo physical and chemical flocculation to form large suspended solid flocs, which are then used in sewage treatment work.

[0003] According to the aerator for river purification disclosed in the patent with the patent number CN219991328U, the device has an aerator body detachably installed inside a through hole at one end of the center of the upper surface of a placement table, which facilitates the installation of the aerator body on the placement table and floating in the river for use. Through the position-changing components arranged at both ends of the placement table, the aerator body can be conveniently moved back to its original position when it drifts away from the use location.

[0004] However, although this device can make the aerator return to its original position, it cannot adjust the depth of the aerator according to requirements during use. In practical applications, the aerator needs to be set to different depths according to different requirements. Existing aerators generally need to replace support rods for adjustment, which is rather troublesome during depth adjustment and reduces the practicality of the device.

[0005] According to a floating-bed aerator disclosed in the patent with the patent number CN219239415U, through the designed first electric push rod, first jaw, second jaw, and second electric push rod, when the aerator body shakes, the first electric push rod and the second electric push rod will respectively push the first jaw and the second jaw to clamp the aerator body, and four wire rope winding boxes will simultaneously release the wire ropes to sink the anchor to the bottom of the water, enabling the aerator to operate stably.
