Zusammenfassung:	The utility model provides a vortex air exhaust assembly of a dry type vortex vacuum pump and the dry type vortex vacuum pump, and belongs to the technical field of pumps. The problem that a vortex air exhaust assembly in an existing vortex vacuum pump is insufficient in sealing performance is solved. The vortex air exhaust assembly of the dry type vortex vacuum pump comprises a movable vortex disc and a static vortex disc, a movable sealing groove is formed in the end face of a movable spiral piece, the movable sealing groove is formed in the spiral line direction of the movable spiral piece, a movable sealing strip is embedded in the movable sealing groove, and the movable sealing strip abuts against the bottom face of a static spiral groove; and/or a static sealing groove is formed in the end face of the static spiral piece, the static sealing groove is formed in the spiral line direction of the static spiral piece, a static sealing strip is embedded in the static sealing groove, and the static sealing str
