Non-contact hard and brittle material ultrasonic crushing device

Abstract

The invention discloses a non-contact hard and brittle material ultrasonic crushing device. The device comprises a device external frame, a high-pressure closing device, a mesh plate, a material fixing bracket, ultrasonic vibration crushing devices, a pressure gauge and an ultrasonic power supply; through connection of four ultrasonic crushing devices and the high-pressure closing device, a transducer and an amplitude change rod achieve multistage magnification and energy gathering effects under driving of two-dimensional excitation signals and a phase difference of 180 degrees to transfer energy and vibration to the surfaces of materials through mediums so as to achieve a non-contact crushing effect; the high-pressure closing device is divorced from a traditional contact pressure application mode; and an upper sealing cover is filled with gas to increase total pressure of the high-pressure closing device to achieve an effect of applying pressure on the surfaces of crushing materials dipped in the mediums, so that the crushing effect is achieved more easily, the problems of pollution and high energy consumption in traditional crushing are effectively solved, and the advantages of ultrasonic vibration crushing are fully exerted.

Description

Technical field: [0001] The invention relates to the field of ultrasonic vibration and non-contact crushing, in particular to a non-contact ultrasonic crushing device for hard and brittle materials. Background technique: [0002] Since the 21st century, various emerging high-performance materials, composite materials, and non-metallic hard and brittle materials have entered the stage of practical application. The crushing of materials is a process with high energy consumption, high steel consumption, and low efficiency. In modern social life, with the improvement of people's requirements for various new materials and materials, there is an urgent need for crushing various materials in terms of product quantity, particle size, particle size distribution, degree of dissociation, material structure, surface physical and chemical properties, etc. . Traditional crushing methods (such as crushing, extrusion, impact, grinding, cutting) have an unbreakable hardness or theoretical s...

AI Technical Summary

Problems solved by technology

Traditional crushing methods (such as crushing, extrusion, impact, grinding, cutting) have an unbreakable hardness or theoretical strength range, and consume a lot of energy; while ultrasonic vibration crushing can pass through transducers and horns The amplification of the high energy density makes the high-frequency vibration impact the crushed materials to destroy their materials; but for the contact crushing of electronic materials (such as polysilicon), a large amount of contact pollution will be generated, resulting in excessive waste of materials. At present, there is an urgent need for a A non-contact ultrasonic crushing device for hard and brittle materials
