The invention provides a pellet-type air return pipe device for a filling machine. The pellet-type air return pipe device comprises an air return pipe. A pellet groove is formed in the lower portion of the air return pipe, and the bottom end of the air return pipe is connected with the top end of the pellet groove. The pellet groove is a hollow pipe with the internal diameter being D. The bottom end of the pellet groove is sealed, a groove hole is formed in the side face of the pellet groove, and a sealing pellet is arranged inside the pellet groove. The diameter of the sealing pellet is R, wherein R is larger than d and smaller than 2d, and D is larger than R and smaller than R+0.5 mm. the density of liquor is rho, and the density of the sealing pellet is rho, wherein rho is larger than 0.3rho and smaller than 0.7rho. The pellet groove is formed in the bottom of the air return pipe, the sealing pellet which can flexibly move is arranged in the pellet groove, due to the fact that ...
