Zusammenfassung:	The invention discloses a smoke purifying device. The problems that an existing smoke purifying device has to be stopped when a filter net needs to be replaced, thus, the schedule of a production line is influenced, and the welding performance of products is even influenced are effectively solved. The smoke purifying device comprises a gas inlet pipeline, a transverse sleeve is fixed to the lower end of the gas inlet pipeline, an exhaust pipeline is fixed to the lower end of the transverse sleeve, the transverse sleeve is internally and slidably connected with a circular column, and the circular column is in sealing connection with the transverse sleeve and is internally provided with a left side through hole and a right side through hole which are perpendicular to each other and do not cross; an air cylinder is rotationally connected to the right side of the circular column, and thus, a structure that the air cylinder pushes the circular column to slide in the transverse sleeve is formed; and a curved groove
