The invention relates to a three-dimensional fluidized centrifugal fan for a sweeper. The three-dimensional fluidized centrifugal fan comprises a volute, a fan impeller and a main shaft, wherein the fan impeller comprises a front disc, a rear disc and a plurality of three-dimensional twisted blades; the two sides, which are attached to the front and rear discs, of each three-dimensional twisted blade are defined as a front side and a rear side respectively; one ends, close to the axis of the fan impeller, of the front side and the rear side are inlet ends, one ends, away from the axis of the fan impeller, of the front side and the rear side are outlet ends ; a front profile inlet angle of 20 to 30 degrees is formed between a blade curved surface tangent line at the front side inlet end anda concentric circle tangent line passing through the front side inlet end on the front disc, a front profile outlet angle of 65 to 75 degrees is formed between a blade curved surface tangent line atthe front side outlet end and a concentric circle tangent line passing through the front side outlet end on the front disc, a rear profile inlet angle of 20 to 30 degrees is formed between a blade curved surface tangent line at the rear side inlet end and a concentric circle tangent line passing through the rear side outlet end on the rear disc, and 75 to 85 degrees are formed between the blade curved surface tangent line at the rear side outlet end and the concentric circle tangent line passing through the rear side outlet end on the rear disc.
Description
technical field [0001] The invention relates to the field of centrifugal fans, in particular to a three-way fluidized centrifugal fan used for cleaning vehicles. Background technique [0002] my country's road sweeping vehicles basically meet the requirements in terms of cleaning performance such as cleaning ability and dust removal effect, but there are still relatively large defects in terms of noise, energy saving, and efficiency, especially the core component of the road sweeping vehicle. High energy consumption, low efficiency and other issues. When the road sweeper is running under normal working conditions, the fan speed is high and the air volume is large, but the efficiency is low; when the road conditions are bad, it is necessary to start the powerful suction sweeping mode, and the fan needs to run at a higher speed to generate greater flow and The higher the negative pressure, the higher the energy consumption and the louder the noise. At present, fans for sweepi...
