The application relates to the technical field of ultrasonic suspension, in particular to an ultrasonic suspension device based on a lotus-style expansion array. The ultrasonic suspension device comprises a power module, a motion controller, a driver, a two-dimensional rotating device and an ultrasonic phased array, the ultrasonic phased array is uniformly provided with ultrasonic wave emitters, and the two-dimensional rotating device is connected with the ultrasonic phased array through a transmission device. The ultrasonic suspension device provided by the application realizes automatic and intelligent suspension control through the joint use of the motion controller and the two-dimensional rotating device; through the design of the spherical ultrasonic phased array, the phase of the ultrasonic wave emitters is accurately controlled by combining the motion controller and the driver, the accurate control of the position of an object is realized, and the demand of complex operation is met; through the adoption of the two-dimensional rotating device, each ultrasonic phased array is independently rotated, the shape of the container can be changed to adapt to different space environments, and the application range is widened.

The application discloses a standing wave suspended nanocellulose directional drying and shaping device, which comprises an ultrasonic wave suspender body, and further comprises U-shaped heating pipes, at least four of which are arranged in two groups, and two groups of the U-shaped heating pipes are slidably arranged on the ultrasonic wave suspender body; the two groups of the U-shaped heating pipes are oppositely arranged on two sides of an ultrasonic wave suspension area, and a first drying space for drying the suspended nanocellulose material is formed between the two groups of the U-shaped heating pipes. The standing wave suspended nanocellulose directional drying and shaping device can form a uniform and closed first drying space by oppositely arranging two groups of the U-shaped heating pipes on two sides of the ultrasonic wave suspension area, so that the suspended nanocellulose is uniformly heated; the U-shaped heating pipes are slidably arranged on the ultrasonic wave suspender body, the distance between the heating pipes and the material is reduced when the U-shaped heating pipes move towards each other, the heating intensity is improved, the operation is simple, and the size of the first drying space and the heating intensity can be quickly changed.
