ULTRASONIC METHOD FOR UNLOADING A SOLID BULK MATERIAL Russian patent published in 2022 - IPC F28G7/00 B08B7/02 B08B9/44 

FIELD: conveying.

SUBSTANCE: invention relates to a method for unloading a solid bulk material from the tubular space of a multi-tube apparatus. The method for unloading a solid bulk material from the tubular space of a multi-tube apparatus consists in affecting the apparatus with ultrasonic oscillations formed by ultrasonic emitters in acoustic contact with the apparatus, wherein the effect of ultrasonic oscillations is executed in the frequency deviation mode with continuous forced changing of the instantaneous working frequency of ultrasonic oscillations in the ultrasonic frequency range with a set level of discreteness - the amount of change in the instantaneous frequency, and acoustic contact is ensured by the rigid connection of the ultrasonic emitters and the apparatus, wherein the solid bulk material constitutes a material with a particle size in the ranges from 20 to 60% of the inner diameter of the tube of the apparatus.

EFFECT: method provides a possibility of optimising the technological process due to the reduction in the time and labour consumption for unloading a solid bulk material from a multi-tube apparatus.
