The invention belongs to the technical field of flotation machines, and particularly relates to a large inflation self-suction flotation machine which comprises a groove body, a stirring mechanism with an impeller and an overflow weir, the height of the impeller meets the condition that h1/H is equal to 20-30% and/or h2/H is equal to 35-45%, h1 is the shortest distance between the bottom face of the impeller and the bottom of the groove body, and/or h2 is the shortest distance between the bottom face of the impeller and the bottom of the groove body. H2 is the shortest distance between the top surface of the impeller and the bottom of the tank body, and H is the shortest distance between the overflow weir and the bottom of the tank body. According to the large inflatable self-suction pulp flotation machine, the two functions of pulp suction and flotation separation can be achieved at the same time under the condition that the overall energy consumption is not increased or slightly increased; and multi-groove
