DUAL-SIDE DUAL-GROOVE PARALLEL TYPE OIL-FREE VORTEX AIR COMPRESSOR

WIPO Patent Application WO/2020/233108

A1

Provided is a dual-side dual-groove parallel type oil-free vortex air compressor. The vortex air compressor mainly comprises two vortex fixed discs (2, 3) and a dual-side vortex tooth movable disc (1). One side end face of each of the vortex fixed discs (2, 3) is provided with vortex teeth (21, 31), both side end faces of the dual-side vortex tooth movable disc (1) are provided with vortex teeth III (11), and the two vortex fixed discs (2, 3) and the dual-side vortex tooth movable disc (1) jointly enclose two air compression channels (25, 35) located on two sides respectively; the vortex teeth (11, 21, 31) on the same end face are arranged to be of a dual-groove parallel type structure, and the air compression channel (25, 35) on the same side is further divided into two channels by means of the dual-groove parallel type structure, thereby facilitating an increase in the displacement of the vortex air compressor; and after air is introduced from an air inlet (210) located in a circumferential face of the vortex fixed disc (2), the air is discharged from the center of the vortex air compressor after being compressed by means of a plurality of compression channels. The technology has the advantages of large air displacement and more stable operation.
