Problems solved by technology

[0002] Ultrafine powder is usually divided into micron-scale, sub-micron-scale and nano-scale powders, which can be prepared by chemical and physical methods, but no matter what kind of ultrafine powder is prepared, the fine particles tend to aggregate together to form Agglomerated particles, this spontaneous aggregation tendency will have an adverse effect on the process and performance of ultrafine powders, especially metal ultrafine powders, the particles themselves have a certain charge, and the bonding force of agglomeration is stronger and the impact is greater
[0003] After the metal ultrafine powder is prepared, it is usually sieved by an ultrasonic vibrating sieve to separate particles with various particle size distributions, remove agglomerated particles with strong binding force and other impurities, and obtain metal ultrafine powder with uniform particle size , but whether it is sieved in the form of ultrasonic circular vibrating sieve or linear sieve, it is directly fed from the top of the equipment to the screen without any feeding treatment, resulting in some agglomerated particles with weak binding force still agglomerated in the sieve. One piece does not separate or pass through the screen holes when the screen vibrates, but is sieved out as non-passing objects, and the non-passing objects are physically crushed and then sieved again. This method requires repeated operations, increases the process, and improves efficiency. Low, so the feed treatment should be done before sieving the freshly prepared metal ultrafine powder to disperse the particles

Abstract

The invention discloses an ultrasonic material distribution structure. The structure is composed of a shell, a material distribution plate, a transmission plate, connecting columns, a fixing plate, afeeding port, a transmission rod and an ultrasonic transducer, and an original feeding mode of screening equipment is replaced. According to the structure, through the high-frequency vibration of theultrasonic transducer, the material distribution plate is vibrated, the amplitude on the powder body at each position of the material distribution plate is different, so that the powder body is stressed unevenly, the binding force of agglomeration particles is destroyed, the agglomeration particles are out of balance, the powder is dispersed to the periphery, so that the effect of particle dispersion is achieved; and the material distribution plate is inclined downwards by a certain angle, the powder particles can fall out dispersedly under the amplitude motion force of the material distribution plate and the self-gravity, so that the powder is screened more sufficiently by subsequent screen meshes, and repetitive screening procedures are reduced.

technical field [0001] The invention belongs to the technical field of vibrating screen equipment, and in particular relates to an ultrasonic material distribution structure. Background technique [0002] Ultrafine powders are usually divided into micron, submicron and nanoscale powders, which can be prepared by chemical and physical methods, but no matter which method of ultrafine powder is prepared, the fine particles tend to aggregate together and form Agglomerated particles, this spontaneous aggregation tendency will adversely affect the process and performance of ultra-fine powder, especially metal ultra-fine powder, the particles themselves have a certain charge, and the binding force of agglomeration is stronger and the impact is greater. . [0003] After the metal ultrafine powder is prepared, it is usually sieved by an ultrasonic vibrating sieve to sieve particles of various particle size distributions, remove the agglomerated particles with strong binding force an...
