The invention relates to the technical field of strip cleaning, and discloses an ultrasonic suspension cleaning system for strips, which comprises a cleaning pool, a cleaning chamber is fixedly connected in the cleaning pool, tensioning rollers for keeping the strips tight are symmetrically and rotatably connected to the bottom and the upper part of the cleaning chamber, a flow guide seat is rotatably connected to the side wall of the upper end of the cleaning chamber, and a flow guide plate is arranged on the flow guide seat. And the lower end of the flow guide seat adopts an inverted trapezoidal design and is used for guiding oil stains to float upwards and converge to the edge of the cleaning chamber. The ultrasonic suspension cleaning system for the strip can effectively solve the problems that in the prior art, in the cleaning process of the metal strip, generated oil stains float on the upper layer of tank liquid, are prone to secondary attachment when the strip is discharged out of the liquid and are difficult to thoroughly wash away by clear water, and high-density solid impurities generated during cleaning are stirred and suspended under ultrasonic vibration, so that the cleaning effect is poor. After entering the contact area of the roller body and the strip, the strip surface is damaged, spot residues are formed, and the strip quality is reduced.

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.
