Abstract: Provided are dynamic sealing structure and rotary kiln apparatus. Dynamic sealing structure includes kiln tail, discharging cover, sealing mechanism, guiding mechanism and balancing device. Discharging cover includes discharging cover cylinder and discharging cover end face connected to same, discharging cover cylinder is arranged on outer side of circumferential wall of kiln tail in sleeving manner, and discharging cover end face and end face of the kiln tail are arranged at intervals. Sealing mechanism is arranged between discharging cover cylinder and kiln tail and is connected to inner wall of discharging cover cylinder. Guiding mechanism is arranged between inner wall of discharging cover cylinder and outer side of kiln tail, and is located on one side or two sides of sealing mechanism in axial direction of rotary kiln, rotating gap is provided between guiding mechanism and kiln tail, and balancing device is connected to outer side of the discharging cover cylinder.

Abstract: The present invention discloses a method, a system, and a mobile terminal for dynamically capturing a face for video taking, which adjusts the positions of a face recognition camera and a main camera according to face position information collected by the face recognition camera during shooting, such that an image of a person is taken at a central area of the picture, and at the same time, collects an original image in a visual angle of the main camera. The present invention can realize dynamic capture of shooting object positions to promptly take a picture of a face.
