DEVICE FOR AIR SUPPLY ONTO THE INNER SURFACE OF A CYLINDRICAL ARTICLE Russian patent published in 2005 - IPC

FIELD: equipment for drying of inner surfaces of cylindrical components in the processes of their manufacture or repair.

SUBSTANCE: the invention is pertaining to equipment for drying of inner surfaces of cylindrical components in processes of their manufacture or repair and is intended for improvement of the quality of drying of these surfaces. The device contains a means for provision of circulation of the drying air, a base, a located on the base movable support for article and a hollow air guiding working head fixed on the base. The means of provision of an air circulation is made in the form of a device forming rarefaction in the working head. The side surface of the working head is made in the form of a treated surface, and its cavity through the hole made in the base communicates with the device forming rarefaction. The support is made in the form of a ring with a bulge and is mounted on the base with a capability of rotation, and the side surface of the working head has two beside located longitudinal grooves, the walls of which form a longitudinal protrusion. At that one of the grooves communicates with the cavity of the working head through the window made in its wall and is supplied with two tightening aprons. And the ratio of the area of its window to the area of the hole of the base may be chosen from the range of 0.4 up to 0.6.

EFFECT: the invention ensures improvement of the quality of drying of the cylindrical components inner surfaces in the processes of their manufacture or repair.
