The invention discloses a device and a method for regulating the blanking of an elliptical cross section of a vertical sintering waste heat recycling system, belongs to the field of gravitational blanking regulation and control in waste heat resource efficient recycling and utilization of a metallurgy industry, and solves the problem of variation and fluctuation of sintered ore blanking quantity, variation of sintered ore size or decrement of waste heat recycling efficiency caused by temperature segregation. The device comprises regulating bars, circular ring platforms, an elliptical section, a transition section, a cylindrical section, a handle, bolt holes, bolts, a coarse section and a sintered ore vertical type cooling tank body lower conical section. By arranging an ore blanking speed local regulating device, the inherent defect of non-uniform heat exchange caused by the lack of a grain size distribution control means of a sintered ore vertical type cooling tank body and air leakage at the edge of a pre-stored section can be overcome, and the adaptability of a vertical type sintering waste heat recycling device on multiple working conditions and variable working conditions can be expanded; meanwhile, compared with a pull-out type cylindrical section regulating bar, an elliptical bar rotary regulating device is capable of reducing the operation space outside the tank body.
