Abstract:
PROBLEM TO BE SOLVED: To stably obtain a high washing ability in a dry ice snow washing device.SOLUTION: A nozzle 190 includes a large diameter part 190a, a reduced-diameter part 190b and an enlarged-diameter part 190c which are located in the order along an axial direction of the nozzle 190. The large diameter part 190a is connected with a mixing part and has a specified inner diameter. The reduced-diameter part 190b is connected with the large diameter part 190a, has an inner diameter which is reduced as being separated from the large diameter part 190a and contains a minimum diameter part 193 located on the boundary with the enlarged-diameter part 190c. The enlarged-diameter part 190c is connected with the reduced-diameter part 190b and has an inner diameter which is enlarged in a specified proportion as being separated from the reduced-diameter part 190b, and a tip of the enlarged-diameter part 190c is an injection port 195 of the nozzle. An inner circumferential surface 192 of the reduced-diameter part 190b is curved along an arc of a virtual ellipse Chaving a major axis parallel to the axial direction of the nozzle 190, toward the large diameter part 190a from the minimum diameter part 193 on a longitudinal plane.SELECTED DRAWING: Figure 2
