Abstract

A method is provided for fixedly joining a cloth, a cloth-like fabric or a synthetic mesh to a filter plate using a flanged cloth connector ring. The flanged cloth connector ring is attached to the filter cloth around the feed port of the cloth and inserted into a receiving channel in the filter plate. A locking ring or a distribution ring may be inserted into the channel adjacent to the connector ring to retain the connector ring and attached filter cloth in place. Filter cloths may be individually and independently attached to each side of a filter plate using a cloth connector ring.

Claims (23)

1. A connector for attaching a filter cloth to a filter plate in a filter press, comprising:

collar portion configured to couple to the perimeter of a central opening on the filter cloth, said collar portion having a substantially flat surface configured to abut a first side of the filter plate; and

a tab portion extending at an angle relative to the collar portion configured to engage a recess in the filter plate, wherein the tab portion includes a radially outer surface that is inclined at an obtuse angle relative to the flat surface of said collar portion and wherein the radially outer surface is configured to abut an inclined surface of the filter plate, and a tab clip extending radially outwardly from the radially outer surface of said tab portion for engaging a bore of the filter plate.

2. The connector of claim 1 , further comprising serrations on a radially inner surface of the tab portion.

3. The connector of claim 1 , further comprising a lock ring for securing the tab portion in the recess.

4. The connector of claim 1 , wherein the tab portion extends substantially perpendicular to the collar portion.

5. The connector of claim 1 , wherein the collar portion and tab portion are formed of a material selected from the group consisting of rubber, plastic and mixtures thereof.

6. The connector of claim 1 , wherein the collar portion forms an annular ring having a hole corresponding to a hole of the filter cloth.

7. The connector of claim 1 , wherein the tab clip includes a first surface extending perpendicular to the tab portion, a second surface extending parallel to a longitudinal axis of the connector and a third and forth surface extending at an angle relative to the longitudinal axis, wherein the third and fourth surface intersect at to form a point at an end of the connector.

8. The connector of claim 1 , wherein the collar portion is attached to a central opening of a filter cloth.

9. The connector of claim 1 , wherein the collar portion forms an annular opening that is larger than an opening of a filter plate to which the connector is attached.

10. A connector for attaching a filter cloth to a filter plate in a filter press, comprising:

a collar portion configured to couple to the perimeter of a central opening on the filter cloth;

a tab portion extending at an angle relative to the collar portion configured to engage a recess in the filter plate; and

a tab clip extending from the tab portion for engaging a bore of the filter plate, wherein the tab clip includes a first surface extending perpendicular to the tab portion, a second surface extending parallel to a longitudinal axis of the connector and a third and fourth surface extending at an angle relative to the longitudinal axis, wherein the third and fourth surface intersect at to form a point at an end of the connector.

11. The connector of claim 10 , further comprising serrations on a radially inner surface of the tab portion.

12. The connector of claim 10 , further comprising a lock ring for securing the tab portion in the recess.

13. The connector of claim 10 , wherein the tab portion extends substantially perpendicular to the collar portion.

14. The connector of claim 10 , wherein the collar portion and tab portion are formed of a material selected from the group consisting of rubber, plastic and mixtures thereof.

15. The connector of claim 10 , wherein the collar portion forms an annular ring having a hole corresponding to a hole of the filter cloth.

16. The connector of claim 10 , wherein the tab portion includes a radially outer surface that is inclined relative to a longitudinal axis of the connector and wherein the outer surface is configured to abut an inclined surface of the filter plate.

17. The connector of claim 10 , wherein the collar portion has a substantially flat surface extending perpendicular to a longitudinal axis, which is configured to abut a first side of filter plate.

18. The connector of claim 10 , wherein the collar portion is attached to a central opening of a filter cloth.
