Turbo drying by air knife

摘要

A device for drying a work piece, preferably in the form of a shrink fit chuck, that previously been subjected to an application of a liquid and is essentially rotationally symmetrical around a longitudinal axis of the work piece; the device has at least one air-conducting device that encompasses the work piece in order to convey an air flow in the direction along the longitudinal axis of the work piece and has at least one blower device that directs a radial air flow at the work piece.

1. A device for drying a work piece in the form of a shrink fit chuck, wherein the work piece has previously been subjected to an application of a liquid and is essentially rotationally symmetrical around a longitudinal axis of the work piece, the device comprising:
at least one air-conducting, device in the form of an air-conducting bell that encompasses the work piece at least during a drying cycle in order to convey an air flow in the direction along the longitudinal axis of the work piece, wherein a diameter of an interior formed by the air-conducting bell is not constant, with a diameter of the air bell after a section with an essentially constant diameter increasing toward an outflow side and transitioning into another section there with an essentially constant diameter, and at least part of the drying air flowing through the air-conducting bell enters the air-conducting bell through at least one first opening, which is oriented so that a part of the air flow traveling through it into the air-conducting bell strikes the surface of the work piece to be dried in the form of a radial air flow, and wherein the air bell is situated on an inside of an air conduit so that at least part of the air flow used for the drying is guided against an outside of the air bell in order to then flow into the air bell via the at least one first opening and flow away via the interior of the air bell; and the device has at least one blower device that directs the radial air flow at the work piece.
