Abstract

An apparatus and methods secure modular repair plugs to one another to repair different sized cells of a screen. A modular repair plug is configured to attach to another modular repair plug to create an extended modular repair plug. The modular repair plug can fit within a first, smaller cell, and the extended modular repair plug can fit within a larger second cell.

First claim

The invention claimed is:

1. An apparatus comprising:
a first modular repair plug shaped for insertion into a shale shaker screen wherein the first modular repair plug has a first width defined between a first end and an opposite second end of the first modular repair plug and a first length defined between a first side and an opposite second side of the first modular repair plug;
a second modular repair plug shaped for insertion into a shale shaker screen, wherein the second modular repair plug has a second width;
a first securing mechanism on a side of the first modular repair plug configured to secure the first modular repair plug to the second modular repair plug to form an extended modular repair plug having a combined width; and
a groove extending across the first width and the first length of the first modular repair plug such that the groove is provided above the first securing mechanism when the first modular repair plug is in an upright position.

2. The apparatus of claim 1 further comprising:
a second securing mechanism on the second modular repair plug to engage the first securing mechanism of the first modular repair plug.

3. The apparatus of claim 2 wherein the first securing mechanism is a protrusion extending from the first modular repair plug and the second securing mechanism is a pocket formed in the second modular repair plug wherein insertion of the protrusion into the pocket attaches the first modular repair plug to the second modular repair plug.

4. The apparatus of claim 1 wherein the combined width is greater than the first width of the first modular repair plug and the second width of the second modular repair plug.

5. The apparatus of claim 1 wherein at least one of the first modular repair plug and the second modular repair plug fit in a cell of the shale shaker screen.

6. The apparatus of claim 1 further comprising:
a ridge on a first cross-member of a grid of the shale shaker screen, wherein the ridge engages the groove of the first modular repair plug.

7. The apparatus of claim 6 wherein the ridge is within an interior of a first cell on the first cross-member or a second cross-member of the grid of the shale shaker screen.

8. The apparatus of claim 7 , wherein the groove extends across the first length of the first modular repair plug and the combined width of extended modular repair plug.

9. The apparatus of claim 1 wherein the first modular repair plug is removably secured to the second modular repair plug and further wherein the first modular repair plug is separable from the second modular repair plug without damaging the first modular repair plug or the second modular repair plug.

10. An apparatus comprising:
a first modular repair plug shaped for insertion into a shale shaker screen wherein the first modular repair plug has a first width;
a second modular repair plug shaped for insertion into the shale shaker screen wherein the second modular repair plug has a second width;
a first securing mechanism on at least one side of the first modular repair plug configured to secure the first modular repair plug to the second modular repair plug to form an extended modular repair plug having a combined width; and
a groove provided about an entire perimeter of the first modular repair plug such that the groove is provided above the first securing mechanism when the first modular repair plug is in an upright position.
