Impeller type aerator

Abstract

The invention provides an impeller type aerator. The impeller type aerator includes a first motor, an impeller, connection rods, and floating bodies; first ends of the connection rods are fixedly connected to the first motor; second ends of the connection rods are fixedly connected to the floating bodies; an output shaft of the first motor is fixedly connected to the impeller; the impeller type aerator includes a first drainage ring and drainage units; each drainage unit include a drive device and a second drainage ring, a fixing end of the drive device is connected to the corresponding connection rod, the second drainage ring is slidingly connected to an output end of the drive device in the axial direction of the second drainage ring, and the first drainage ring is fixedly connected to the output end; the first drainage ring and the second drainage ring have the same structure; the second drainage ring extends outward in the axial direction and is provided with a partition plate; and the first drainage ring and the second drainage ring are positioned under the impeller. The impeller type aerator can adjust the depth of oxygenation.

Description

technical field [0001] The invention relates to the field of aquaculture equipment, in particular to an impeller type aerator. Background technique [0002] The impeller type aerator is a kind of motor, gasoline engine, diesel engine and other power sources to drive the working parts and make the working parts stir the water body, increase the contact area between the water body and the air, so that the "oxygen" in the air can be quickly integrated into the water body; it can not only Effectively increase the amount of dissolved oxygen in the water body, and can also promote the flow of the water body, thereby improving the water quality. [0003] At present, the common impeller aerators include impeller aerator, waterwheel impeller aerator, jet impeller aerator and water spray impeller aerator, etc. Compared with other impeller-type aerators, the effective aeration area, oxygen-increasing capacity and power efficiency of the impeller-type aerator are superior to other mode...

Problems solved by technology

[0004] However, the current impeller-type aerator can only extract water at a fixed depth in the water body. When the living depth of the cultured aquatic products is greater than the depth that the impeller-type aerator can increase oxygen or the depth of the cultured fish pond is too large, the impeller will Type aerators can only increase o
