Embodiment Construction

[0023] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0024] Such as figure 1 As shown, a new type of ultrasonic horn device, the overall shape of the horn device is cylindrical. The horn device includes a solid slender body with a longitudinal axis, the solid slender body is cylindrical, and the distal end has a diameter of 40 mm. One end of the longitudinal axis is horn-shaped as the distal end, and the other end is provided with a sleeve connection structure as the proximal end. The socket connection structure is a cylinder with a diameter of 48 mm, and a trapezoidal cylindrical transition is adopted between the socket connection structure and the solid slender body. The solid slender body adopts a material that can be vibrated by ultrasonic waves. The standard length of the solid slender body is a single wavelength of ultrasonic waves passing through the material at a selected ultrasonic frequency, and the ...

Abstract

The invention discloses a novel ultrasonic horn device. The novel ultrasonic horn device comprises a solid elongated body of a longitudinal shaft. One end of the longitudinal shaft is in a horn shape and is the far end. The solid elongated body is made of an ultrasonic vibration material. The standard length of the solid elongated body is the single wavelength of ultrasonic waves transmitting the material at the selected ultrasonic frequency. The length of the solid elongated body is within the plus or minus error range of one hundredth of the standard length. The novel ultrasonic horn device is simple and reasonable in design and stable and reasonable in structure.

Description

Technical field [0001] The invention relates to the ultrasonic field, and more specifically, it relates to a new type of ultrasonic horn device. Background technique [0002] Ultrasonic pulverization as a mechanical pulverization method that can effectively obtain fine powder has been more and more widely used in various fields. In some high-intensity ultrasonic applications, the required amplitude is about tens to hundreds of microns. Therefore, it is necessary to use an amplifier to amplify the ultrasonic amplitude. This amplifier is an ultrasonic horn, and can play a role in gathering energy. It can further crush some powders to obtain fine powders that meet the actual application. Therefore, the performance of the horn directly affects the quality of the ultrasonic equipment. [0003] In the traditional method of designing ultrasonic horns, the performance expressions of different shape function horns are complicated, and the calculation and design workload are very large.
