The invention relates to the technical field of kitchen sewage treatment equipment, in particular to a flexible mixture vortex discharge connecting device of a kitchen. The device aims at solving thetechnical problem that a kitchen pipeline is easy to block. In order to solve the technical problem, the flexible mixture vortex discharge connecting device of the kitchen comprises a cone head waterinlet tank, wherein water inlet pipes are spliced into openings formed on the two sides of the cone head water inlet tank; an arc angle tank is fixedly connected with the top of the cone head water inlet tank and internally provided with a driving device; the cone head water inlet tank is internally provided with a vortex generation device; the bottom of the driving device is fixedly connected with the top of the vortex generation device; and a water outlet at the bottom of the cone head water inlet tank is connected with a water inlet at the top of the cone head water collecting tank througha flow guide mechanism. According to the device, cone sheets on a spiral sheet have different diameters; a water flow direction can be changed to generate a vortex; and forward blades and crushing sheets arranged on the forward blades can crush flexible sundries.
