ACOUSTIC THERMAL DRIER Russian patent published in 2011 - IPC F26B9/06 F26B5/02 

FIELD: heating.

SUBSTANCE: drier includes drying compartment with soundproof machines and loading-unloading device, sources of acoustic vibrations, device for supply of heated air to chamber and rotary drive. Drier includes pistons in number of n≥2, which serve as sources of acoustic vibrations and located inside the compartment so that they divide it into sections in the ratio of volumes where movement of pistons is performed in opposite phase, volume V≥2V₁, where V₁ - volume of the compartment section with single-phase movement of piston, which are kinematically connected to controlled drive of their back-and-forth movement by means of rod interacting with slider-crank mechanism and with the pin fixed on the drive shaft disk; at that, between pistons the rod interacts with hinge-lever system providing opposite phase movement of pistons, and blades the width of which is less than inner radius of chamber are installed on inner surface of drying compartment throughout its length. Pistons are arranged in guides and enclosed with grid.

EFFECT: invention shall provide improvement of efficiency and reduction of cost of the drier.
