Abstract

The invention discloses a rotary type air centrifugal force generating device for a centrifugal fan, and belongs to the technical field of centrifugal fans. The rotary type air centrifugal force generating device includes a spiral channel left side wall plate, a spiral channel right side wall plate and a group of spiral channel partition wall plates; the spiral channel left side wall plate is an annular plate, and an inner circular hole of the annular plate corresponds to an air inlet of a volute; the spiral channel right side wall plate is a circular plate; the group of the spiral channel partition wall plates are all arc-shaped plates; the spiral channel left side wall plate and the spiral channel right side wall plate are left-right arranged oppositely; the spiral channel partition wallplates are evenly arranged between the spiral channel left side wall plate and the spiral channel right side wall plate in a spiral mode with the inner circular hole of the left side wall plate as acentral hole, the spiral channel left side wall plate is fixedly connected to the left end of each spiral channel partition wall plate, the right end of each spiral channel partition wall plate is fixedly connected with the spiral channel right side wall plate, and a spiral type centrifugal channel concentrically with the volute shell arranged around the air inlet of the volute shell in an annularmode is formed. The rotary type air centrifugal force generating device has the characteristics of a reasonable structure, high efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of centrifugal fans. Background technique [0002] Centrifugal fan is a general-purpose equipment widely used in industry, agriculture and other industries, and belongs to high-energy consumption equipment.
