Abstract

Alignment device ( 1 ) for adjusting a position of a curved shower bar nozzle flange ( 2 ) relative a permeable outer cylindrical surface ( 3 ) of a drum roll ( 4 ) of for instance a drum washer. The alignment device comprises a body element ( 8 ), an attachment device ( 9 ) and a contact element ( 11 ). The body element has a length adapted to a desired predetermined distance between the end ( 7 ) of the nozzle flange and the outer cylindrical surface ( 3 ). The attachment device ( 9 ) is arranged at a first end ( 10 ) of the body element ( 8 ) for releasably connecting the body element to the nozzle flange end ( 7 ) to extend tangentially therefrom. The contact element ( 11 ) is arranged at a second opposite end ( 12 ) of the body element, said contact element being adapted to abut against said permeable outer cylindrical surface ( 3 ). A method for aligning a nozzle flange using such an alignment device is also provided.

First claim

The invention claimed is:

1. An alignment device for adjusting a position of a shower bar nozzle flange relative to a permeable outer cylindrical surface of a drum roll of a drum washer, the shower bar nozzle flange being at least partly curved, and the shower bar nozzle flange being configured to extend from a nozzle outlet in a shower bar to a nozzle flange end, said nozzle flange end being configured to be tangentially aligned with the permeable outer cylindrical surface, the alignment device comprising:
a body having a length corresponding to a desired predetermined distance between the nozzle flange end and the permeable outer cylindrical surface;
an attacher arranged at a first end of the body for releasably connecting the body to the nozzle flange end to extend tangentially therefrom; and
a contact element arranged at a second opposite end of the body, or forming a portion of the second opposite end of the body, the contact element being arranged to abut against the permeable outer cylindrical surface.

2. The alignment device according to claim 1 , wherein the attacher comprises a clamping device having at least one clamp arranged to provide a clamping force against the nozzle flange end by means of at least one tensioner.

3. The alignment device according to claim 1 , wherein the attacher comprises a groove or slot in or at the first end of the body, the groove or slot having a width adapted to a thickness of the nozzle flange end.

4. The alignment device according to claim 1 , wherein the body comprises a plane body portion arranged to form a tangential extension of the nozzle flange end when connected thereto.

5. The alignment device according to claim 4 , wherein the contact element protrudes downwardly from a plane defined by the plane body portion and has a pointed or curved edge configured to abut against the permeable outer cylindrical surface.

6. The alignment device according to claim 5 , wherein the contact element is provided as a downwardly protruding portion of the body.

7. The alignment device according to claim 4 , wherein the body comprises an end portion being curved upwardly relative to the portion of the body around an axis being perpendicular with a longitudinal direction of the portion of the body.

8. The alignment device according to claim 5 , wherein the contact element is arranged at the second opposite end of the body and forms a right angle therewith, the contact element comprises the curved edge by having a disc shape formed integrally with, or connected to, the body.

9. The alignment device according to claim 1 , wherein the body has a tapered shape, tapering from the first end towards the second opposite end.

10. The alignment device according to claim 9 , wherein the body has a width at the first end adapted to a width of the nozzle flange end.

11. The alignment device according to claim 1 , wherein the first end of the body has a straight edge arranged to make contact along a full length of the body with the nozzle flange end having a straight free end edge.

12. A shower bar nozzle flange system comprising a shower bar nozzle flange being at least partly curved, and being configured to extend from a nozzle outlet in a shower bar to a nozzle flange end, the nozzle flange end being configured to be tangentially aligned with a permeable outer cylindrical surface of a drum roll of a drum washer at a predetermined distance therefrom, the system further comprising the alignment device according to claim 1 .

13. A method for aligning a shower bar nozzle flange relative to a permeable outer cylindrical surface of a drum roll of a drum washer using the alignment device according to claim 1 , the shower bar nozzle flange being at least partly curved, and being configured to extend from a nozzle outlet in a shower bar to a nozzle flange end, the nozzle flange end being configured to be tangentially aligned with the permeable outer cylindrical surface at a predetermined distance therefrom, the method comprising: attaching the alignment device to the nozzle flange end using an attacher, and adjusting a position of the shower bar nozzle flange such that a contact element makes contact with the permeable outer cylindrical surface.

14. The alignment device according to claim 6 , wherein the contact element is provided as a V-shaped or U-shaped stamping in the body.
