Double-layer fan blade for gas-liquid separation

Abstract

The invention discloses a double-layer fan blade for gas-liquid separation, which relates to the technical field of fans. The double-layer fan blade for gas-liquid separation comprises a first hub anda second hub. Three first notches are formed in the circumferential side face of the first hub. First straight rods are in clearance fit with the inner surfaces of the three first notches; the otherend of the first straight rod is fixedly connected with a first fan blade; the peripheral side surface of the first straight rod is fixedly connected with a gear; the peripheral side surface of the first straight rod is fixedly connected with a first fixed block; one surface of the first fixed block is fixedly connected with a first spring; the other end of the first spring is fixedly connected with a second fixed block; and one side surface of the second fixed block is fixedly connected with a circular pipe. By arranging the first fan blade and the second fan blade, the problem that an existing fan blade is only provided with one layer of fan blade is solved; by arranging the gear and the gear sleeve, the problem that the angle of fan blades of an existing fan cannot be adjusted is solved; and by arranging a blade expanding plate, the problem that the size of fan blades of an existing fan cannot be adjusted is solved.

Description

technical field [0001] The invention belongs to the technical field of fans, in particular to a double-layer fan blade for gas-liquid separation. Background technique [0002] The blades of an axial fan push air to flow in the same direction as the shaft. The impeller of the axial flow fan is somewhat similar to the propeller. When it is working, most of the air flow is parallel to the axis, in other words, along the axis. When the inlet airflow is free air with 0 static pressure, the axial fan has the lowest power consumption. When it is running, the power consumption will increase with the rise of the airflow back pressure. Axial flow fans are usually installed on the cabinet of electrical equipment, and sometimes integrated on the motor. Because the axial flow fan has a compact structure, it can save a lot of space and is easy to install, so it is widely used. [0003] Existing fan blades have only one layer of blades. If you want to adjust the air volume of a single-la...
