Abstract

The present disclosure provides a cleaning system, including a first sub-chamber, a second sub-chamber adjacent to the first sub-chamber, and a third sub-chamber adjacent to the second sub-chamber. A first divider is positioned between the first and the second sub-chambers. A second divider is positioned between the second and the third sub-chambers. A vacuum system is coupled to the third sub-chamber to generate a vacuum pressure in the third sub-chamber that is less than a pressure of the first sub-chamber to create a pressure differential to induce a pressurized flow of a first cleaning media from the first sub-chamber to the third sub-chamber through an internal passage of a component positioned in the second sub-chamber. A filtering system is coupled to the first sub-chamber and the third sub-chamber to remove and filter the first cleaning media from the third sub-chamber and return the first cleaning media to the first sub-chamber.

First claim

What is claimed is:

1. A cleaning system, comprising:
a cleaning chamber, comprising:
a first sub-chamber configured to retain a first cleaning medium, the first cleaning medium comprising a plurality of particles having an average diameter of about 0.5 mm to about 3 mm, the plurality of particles being selected from the group consisting of polymeric particles, ceramic particles, glass particles, polymer-coated glass particles, polymer-coated ceramic particles, and combinations thereof;
an agitator coupled to the first sub-chamber, the agitator including one or more propellers configured to initiate and maintain a rotational velocity of the first cleaning medium;
a second sub-chamber adjacent to the first sub-chamber;
a component positioned in the second sub-chamber;
a first divider positioned between the first sub-chamber and the second sub-chamber, the first divider having a first aperture formed therein;
a third sub-chamber adjacent to the second sub-chamber and configured to receive the first cleaning medium;
a second divider positioned between the second sub-chamber and the third sub-chamber, the second divider having a second aperture formed therein, the first aperture and the second aperture being configured to form a fluid path through the second sub-chamber; and
a vacuum system coupled to the third sub-chamber, the vacuum system being configured to generate a pressure in the third sub-chamber that is less than a pressure of the first sub-chamber to induce a pressurized flow of the first cleaning medium from the first sub-chamber to the third sub-chamber, wherein the vacuum system further comprises:
a vacuum pump to establish a pressure in at least one sub-chamber of the cleaning chamber;
a buffer chamber directly coupled to the vacuum pump to modulate the pressure established by the vacuum pump; and
a valve coupled to the buffer chamber and the third sub-chamber of the cleaning chamber; and

a filtering system coupled to the cleaning chamber and configured to filter the first cleaning medium; and

a computer programmed to perform an operation of using the first cleaning medium to clean an inside surface of the component, and an operation of using a second cleaning medium to clean an outside surface of the component, wherein the two operations do not overlap with each other.

2. The cleaning system of claim 1 , further comprising:
a first coupling mechanism removably coupled to the first divider via the first aperture; and
a second coupling mechanism removably coupled to the second divider via the second aperture.

3. The cleaning system of claim 2 , wherein: the component positioned in the second sub-chamber further comprises:
a first end being removably coupled to the first coupling mechanism,
a second end being removably coupled to the second coupling mechanism,
wherein the inside surface of the component defines an internal passage extending from the first end to the second end.

4. The cleaning system of claim 2 , wherein each of the first coupling mechanism and the second coupling mechanism comprises a press-fit mechanism, a clamp, an adhesive, a magnetic chuck, or a combination thereof.

5. The cleaning system of claim 1 , further comprising a first temperature sensor coupled to the first sub-chamber.

6. The cleaning system of claim 1 , further comprising a first vessel coupled to the first sub-chamber, the first vessel having the first cleaning medium therein and being configured to transport the first cleaning medium into the first sub-chamber.

7. The cleaning system of claim 1 , further comprising a second vessel coupled to the second sub-chamber, the second vessel having the second cleaning medium and being configured to transport the second cleaning medium into the second sub-chamber.

8. A cleaning system, comprising:
a plurality of cleaning chambers, each cleaning chamber of the plurality of cleaning chambers comprising:
a first sub-chamber, the first sub-chamber configured to retain a first cleaning medium;
an agitator coupled to the first sub-chamber, the agitator including one or more propellers being configured to initiate and maintain a rotational velocity of the first cleaning medium;
a second sub-chamber adjacent to the first sub-chamber;
a component positioned in the second sub-chamber, the component comprising an internal passage;
a first divider positioned between the first sub-chamber and the second sub-chamber, the first divider having a plurality of first apertures formed therein;
a third sub-chamber adjacent to the second sub-chamber and configured to receive the first cleaning medium; and
a second divider positioned between the second sub-chamber and the third sub-chamber, the second divider having a plurality of second apertures formed therein;

a vacuum system coupled to the third sub-chamber of each cleaning chamber of the plurality of cleaning chambers, the vacuum system comprising a vacuum pump, a buffer chamber, and a valve;
a plurality of leak sensors coupled to the plurality of cleaning chambers; and
a filtering system coupled to the plurality of cleaning chambers, the filtering system being configured to filter the first cleaning medium; and
a computer programmed to perform an operation of using the first cleaning medium to clean an inside surface of the component, and an operation of using a second cleaning medium to clean an outside surface of the component, wherein the two operations do not overlap with each other.

9. The cleaning system of claim 8 , further comprising:
a first coupling mechanism removably coupled to the first divider of each cleaning chamber of the plurality of cleaning chambers via one of the plurality of first apertures; and
a second coupling mechanism removably coupled to the second divider of each cleaning chamber of the plurality of cleaning chambers via one of the plurality of second apertures.

10. The cleaning system of claim 9 , wherein the component positioned in the second sub-chamber of each cleaning chamber of the plurality of cleaning chambers further comprises:
a first end being removably coupled to the first coupling mechanism,
a second end being removably coupled to the second coupling mechanism,
and wherein the inside surface of the component defines the internal passage extending from the first end to the second end.

11. The cleaning system of claim 8 , further comprising a first vessel coupled to the first sub-chamber of each cleaning chamber of the plurality of cleaning chambers, the first vessel including the first cleaning medium and being configured to transport the first cleaning medium into the first sub-chamber of each cleaning chamber of the plurality of cleaning chambers.

12. The cleaning system of claim 8 , further comprising a second vessel coupled to the second sub-chamber of each cleaning chamber of the plurality of cleaning chambers, the second vessel including the second cleaning medium and being configured to transport the second cleaning medium into the second sub-chamber of each cleaning chamber of the plurality of cleaning chambers.
