Abstract
Cleaning air knife elements are assembled in a parallel orientation inside a housing enclosing the air knife assembly and in fluid communication with a compressed air source. In certain embodiments, the air knife elements are spaced apart a distance that orients the cleaning air knife discharge slots directly parallel and in line with the slots of the air nozzle or bar to be cleaned. Air discharging from the air knife discharge slots passes through the discharge slots of the air nozzle to be cleaned, dislodging dust and friable solid buildup from the air nozzle slots. Additionally, the cleaning air jet enters the air nozzle body, further dislodging dust and friable solids from the internal passages of the air nozzle inside the air nozzle body.
Claims14
An air nozzle cleaning tool comprising:
- a housing;
- at least two air knife elements in said housing;
- each air knife element having an air knife discharge slot configured to discharge gas when placed in fluid communication with a gas source, and at least one tab extending from said discharge slot;
- wherein the air knife discharge slot and the at least one tab is adapted to be aligned with a slot in an air nozzle to be cleaned.
A system for cleaning an air nozzle, comprising:
- an air nozzle to be cleaned, said air nozzle having an air nozzle slot;
- a housing sealed to said air nozzle;
- a first and second air knife element in said housing, said first and second air knife element having an air knife discharge slot configured to discharge gas when placed in fluid communication with a gas source, and at least one tab extending from said air knife discharge slot, wherein said air knife discharge slot and the at least one tab is aligned with said air nozzle slot such that said at least one tab is received in said air nozzle slot;
- and a source of compressed air in fluid communication with said first and second air knife element.
An air nozzle and cleaning tool assembly, comprising:
- an air nozzle having an air nozzle body and first and second spaced air nozzle slots;
- a housing sealed to said air nozzle body;
- first and second air knife elements in said housing, each of said first and second air knife elements having an air knife discharge slot configured to discharge gas when placed in fluid communication with a gas source, and at least one tab extending from said air knife discharge slot, wherein said air knife discharge slot and said and at least one tab from each of said first and second air knife elements are aligned with respective air nozzle slots of said air nozzle such that said at least one tab from each of said first and second air knife elements is received in a respective air nozzle slot and gas discharged from said air knife discharge slot of said first and second elements enters a respective air nozzle slot;
- and a source of compressed air in fluid communication with each of said air knife elements.
