Abstract

The invention discloses a centrifugal fan capable of controlling air blowing direction, and relates to the technical field of centrifugal fans. The centrifugal fan capable of controlling the air blowing direction comprises a casing, a frame is mounted at the top of the casing, an air deflector is mounted at the top of the frame, the two sides of the top of the frame are connected with the casing through fixing shafts, an air inlet frame is mounted on one side of the outer surface of the casing, and a supporting frame is connected to the back of the casing. According to the centrifugal fan capable of controlling the air blowing direction, through a first impeller, a second impeller and the air deflector, the fan is started to start the whole centrifugal fan; the centrifugal fan sucks wind power into the casing through the air inlet frame; when the wind power enters the casing, an air outlet passage is formed through inclined blades of the second impeller and inclined blades of the firstimpeller; when air passes through the gap of the air outlet passages formed by the inclined blades of the second impeller and the inclined blades of the first impeller, a certain initial speed pointing to an air outlet is obtained, so that the rotation direction of the wind power in the casing is consistent; and therefore, the backflow situation cannot be generated.

Description

technical field [0001] The invention relates to the technical field of centrifugal fans, in particular to a centrifugal fan with controllable blowing direction. Background technique [0002] The centrifugal fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. The centrifugal fan is widely used in the ventilation of factories, mines, tunnels, cooling towers, vehicles, ships and buildings. Dust extraction and cooling; ventilation and induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household electrical appliances; drying and selection of grain; wind tunnel wind source and inflation and propulsion of hovercraft, etc., centrifugal fan According to the principle of converting kinetic energy into potential energy, the high-speed rotating impeller is used to accelerate the gas, then decelerate and change the flow direction, so that the kine...
