METHOD OF UNLOADING OF HARDENED MATERIAL FROM CONTAINER Russian patent published in 2013 - IPC B65D88/74 

FIELD: packaging industry.

SUBSTANCE: invention relates to unloading and cleaning works in containers containing hardened materials such as paraffin, heating oil, edible fats, potash, and all that. The objectives of this invention are: acceleration of unloading the hardened materials from the containers of arbitrary designs and sizes, saving energy and labor costs, use of cheaper equipment for unloading the hardened materials from the container, including while the cleaning works - release of containers from deposits and dirt on the bottom, walls and internal structures. To solve this problem a method of unloading the hardened materials from the container is proposed, consisting of thermal influence on the materials, the accumulation of the liquid phase, and influence by the liquid phase on the solid one by ultrasonic vibrations followed by draining or pumping the materials in the form of the liquid phase from the container. And the hardened materials the additional influence is made by sound and infrasound vibrations and turbulent jets of heated fluid medium, and as the vibration transducer a quasi-steady wave of deceleration is used behind the part of the supersonic two-phase flow of the wash-off jet of the heated liquid phase of the material.

EFFECT: acceleration of unloading the hardened materials from the containers of arbitrary designs and sizes, as well as saving energy and labor costs.
