In the blower with special-shaped discharge pipe of burner.
A kind of blower for burner with special-shaped discharge pipe, including spiral case, the impeller that is arranged in spiral case and
For the motor of impeller rotation, the rectangular duct of the airflow for generating for wheel rotation is additionally provided in spiral case,
The special-shaped discharge pipe being connected to the end of rectangular duct is additionally provided on the spiral case, the air-flow for enabling wheel rotation to generate
It is discharged by special-shaped discharge pipe, curved surface of the inner wall of the abnormity discharge pipe using smooth transition, the air intake of special-shaped discharge pipe
For a rectangular opening identical with the tip dimensions of rectangular duct, the outlet air end of special-shaped discharge pipe is a circular port, circular port
Area and rectangular opening area 5% of difference no more than lesser area in the two, define the circular port center of circle and rectangular opening be diagonal
Line between line center is that the central datum line of special-shaped discharge pipe, the central datum line and circular port and rectangular opening distinguish institute
Two planes it is vertical, and the central datum line length satisfaction can make it is most short between rectangular opening quadrangle and circular port
Line and central datum line angle β size be 7.5 ° to 15 °.
Preferably, the area equation of the area of the circular port and rectangular opening.
Preferably, the outer wall of the special-shaped discharge pipe is that smooth transition identical with the inner wall shape of special-shaped discharge pipe is bent
Face.
According to the above technical scheme, the beneficial effects of the utility model are:
The utility model is equipped with special-shaped discharge pipe in the rectangular duct end of blower, and one end of special-shaped discharge pipe is rectangle
Mouthful, one end is circular port, and tube wall is then that three-dimensional flow theory is utilized, after CFD analysis and CAD fitting, from rectangular opening to circle
The curved surface of shape mouth smooth transition；Special-shaped discharge pipe is demonstrate,proved from rectangular opening to circular port transitional structure through CFD simulation calculation and practice
It is bright, rectification and diffusion can be carried out to the air-flow in special-shaped discharge pipe, go out wind facies from the end of rectangular duct with existing blower
Than the air-flow flowed out from circular port can be made more uniform, keep blower outlet air more stable, and can reduce blower in identical work
The power consumed under the conditions of work enables burner normally, efficiently to work to improve the efficiency and performance of blower.
