Energy-saving plug-flow aerator

Abstract

The invention discloses an energy-saving plug-flow aerator which comprises a cabinet, a motor arranged on the upper side of the cabinet, and a stirring assembly flexibly connected to the lower side of the cabinet, wherein a gear set is arranged in the cabinet; an output shaft of the motor is connected with the gear set in a transmission mode; the motor can drive the stirring assembly to rotate through the gear set; the cabinet is rotatablely provided with a support shaft; the stirring assembly comprises a driving shaft sleeve, a driven shaft sleeve and a stirring disk; a driving shaft sleeve locating sleeve is arranged on one shaft end of the output shaft of the gear set; a driven shaft sleeve locating sleeve is arranged on one shaft end of the support shaft; the driving shaft sleeve and driven shaft sleeve are respectively hinged with a connecting piece; the stirring disk is formed by integrally connecting two disk bodies of which the central axes are mutually perpendicular; and the two disk bodies are respectively correspondingly connected with two connecting pieces rotatablely through a rotating shaft. The energy-saving plug-flow aerator can implement circulating aeration on the river course sediment and water body deep layer, and has favorable water body self-purification effect. The energy-saving plug-flow aerator has the advantages of high working stability, energy saving and high applicability.

Description

technical field [0001] The invention relates to the technical field of sewage and river bottom mud treatment, and specifically provides an energy-saving push-flow aerator capable of bottom mud treatment and water body self-purification. Background technique [0002] At present, the aerators used for water treatment usually adopt the following two structures: 1) the aerator has a hollow part with a hole-like structure, and the hollow part is used to directly blow air into the water to achieve the purpose of increasing oxygen; The scope of application of hollow parts is limited, and it can be used in sewage treatment plants, but it is not very convenient for applications such as river courses. 2) The aerator has a motor and a blade similar to a propeller, and the motor drives the blade to rotate to agitate the water body for aeration; but this type of aerator has low working efficiency and consumes a lot of energy. In particular, the biggest disadvantage of the aerators with ...

[0002] At present, the aerators used for water treatment usually adopt the following two structures: 1) the aerator has a hollow part with a hole-like structure, and the hollow part is used to directly blow air into the water to achieve the purpose of increasing oxygen; Hollow parts have a limited scope of application and can be used in sewage treatment plants, but it is not very convenient for applications such as rivers

2) The aerator has a motor and a blade similar to a propeller, and the motor drives the blade to rotate to agitate the water body to increase oxygen; but this type of aerator has low working efficiency and consumes a lot of energy

In particular, the biggest disadvantage of the aerators with the above two structures is that they can only add oxygen to the upper part of the water body, and cannot fully realize the oxygenation of the river sediment and the deep part of the water body, so that the self-purification effect of the water body is relatively poor.
