Abstract

A wedging apparatus for a vibrating separator including an outer polygonal surface to secure a screen to the vibrating separator, wherein the outer polygonal surface extends substantially along the length of a screening surface of the vibrating separator is disclosed. A screen for a vibratory separator including a frame having a top surface and a bottom surface, and at least one filter element connected to the frame, wherein the bottom surface comprises a wedge engagement profile is also disclosed. A vibrating separator apparatus including a first side wall, a second side wall opposite the first side wall, a bottom wall connecting the first side wall and the second side wall, a first screen having a top surface and a bottom surface, at least one wedging apparatus disposed along the length of the bottom surface of the first screen is also disclosed.

First claim

What is claimed is:

1. A wedging apparatus comprising:
a polygonal shaped structure having a first outer surface configured to secure a screen to a vibrating separator, the first outer surface comprising a bottom surface, a top surface opposite the bottom surface, a first end surface and a second end surface opposite the first end surface, and the first and second end surfaces join the top and bottom surfaces and define a length of the polygonal shaped structure,
wherein the polygonal shaped structure has a horizontal axis and a height defined between the top and bottom surfaces of the first outer surface and is configured to apply force on the screen, wherein the top surface is provided at a first angle of about zero degrees with respect to the horizontal axis and the bottom surface is provided at a second angle of about zero degrees with respect to the horizontal axis such that the height of the polygonal shaped structure is constant and continuous across at least a majority of the length of the polygonal shaped structure defined between the first and second end surfaces of the first outer surface, and further wherein the majority of the length consists of at least 50% of the length of the polygonal shaped structure defined between the first and second end surfaces of the first outer surface.

2. The wedging apparatus of claim 1 , wherein the first outer surface further comprises a first side and a second side, wherein the first side joins a first edge of the top surface and a first edge of the bottom surface, and the second side joins a second edge of the top surface and a second edge of the bottom surface.

3. The wedging apparatus of claim 1 , wherein the first outer surface comprises at least one from the group of a composite, a polyurethane, and a polypropylene, wherein the composite comprises glass-filled polypropylene.

4. The wedging apparatus of claim 1 , wherein the polygonal shaped structure has an inner core providing a supporting structure to the wedging apparatus wherein the inner core comprises at least one selected from a group of a metal, a polyurethane, a polypropylene, and a nylon.

5. The wedging apparatus of claim 1 , wherein the bottom surface comprises a substantially flat surface.

6. The wedging apparatus of claim 1 , wherein the bottom surface comprises a first surface and a second surface, wherein the first surface has an angle ranging from about 2 degrees to about 45 degrees with respect to the second surface of the bottom surface such that an apex is provided on the bottom surface and said apex extends in a longitudinal direction along the length of the polygonal shaped structure, wherein the first and second surfaces of the bottom surface are substantially flat surfaces beginning at said apex and extending continuous and uninterrupted across entire lengths of the first and second surfaces away from said apex.

7. The wedging apparatus of claim 1 , wherein the bottom surface comprises a first surface that is substantially flat and a second surface having an angle ranging from about 2 degrees to about 45 degrees with respect to the first surface of the bottom surface.

8. The wedging apparatus of claim 1 , wherein the top surface comprises a substantially flat surface.

9. The wedging apparatus of claim 1 , wherein the top surface comprises a first surface having an angle ranging from about 2 degrees to about 45 degrees with respect to a second surface of the top surface such that an apex is provided on the top surface and said apex extends in a longitudinal direction along the length of the polygonal shaped structure.

10. The wedging apparatus of claim 1 , wherein at least one surface selected from the top surface and the bottom surface comprises a screen engagement profile.

11. The wedging apparatus of claim 1 , further comprising a stop disposed on the first or second at least one end surface.

12. The wedging apparatus of claim 1 , further comprising one or more protrusions usable for removing the wedging apparatus from a vibratory separator basket of the vibrating separator.

13. The wedging apparatus of claim 4 , wherein the supporting structure comprises rods.

14. The wedging apparatus of claim 11 , wherein one or more apertures are located within the stop disposed on the at least one end surface.

15. The wedging apparatus of claim 1 , wherein a shape of the bottom surface is a continuous and uninterrupted V-shape having an apex extending in a longitudinal direction along the length of the polygonal shaped structure.

16. The wedging apparatus of claim 1 , wherein a shape of the bottom surface of the first outer surface engages a wedge engagement profile of the screen.

17. A wedging apparatus comprising:
a polygonal shaped structure having a length defined between a first end and a second end located opposite with respect to the first end of the polygonal shaped structure and an outer surface configured to secure a screen to a vibrating separator, the outer surface comprising a bottom side, a top side opposite the bottom side, and the first end and the second end joining the top side and the bottom side, wherein the bottom side comprise a first angled surface and a second angled surface that extend outwardly and form an apex on the bottom side that extends in a longitudinal direction of the polygonal shaped structure along the length of the polygonal shaped structure, wherein the first and second angled surfaces begin at said apex, extend continuously and uninterrupted across entire lengths of the first and second angled surfaces away from said apex and terminate at opposing sides of the outer surface, wherein the opposing sides join the top and bottom sides and the first and second ends, and further wherein the bottom side has a bottom surface extending the along the length of the polygonal shaped structure from the first end to the second end and consisting of the apex connecting the first and second angled surfaces such that a height of the polygonal shaped structure is defined between the top side of the outer surface and the apex at the bottom edge of the bottom side of the outer surface.

18. A wedging apparatus comprising:
a first polygonal shaped structure having a first outer surface comprising a bottom surface, a top surface opposite the bottom surface, a first end surface and a second end surface opposite the first end surface, wherein at least the second end surface joins the top surface and the bottom surface, wherein the first polygonal shaped structure has a first height defined between the top and bottom surfaces, a length defined between the first and second end surfaces, a first stop provided adjacent to the first end and having a second height, wherein the first height increase along the length of the first polygonal shaped structure from the second end surface to the first stop and the second height of the first stop is greater than the first height of the first polygonal shaped structure; and
a second polygonal shaped structure having a second outer surface comprising a bottom surface, a top surface opposite the bottom surface, and at least one end surface joining the top surface and the bottom surface of the second polygonal shaped structure, wherein the second polygonal shaped structure has a first height defined between the top and bottom surfaces, a length defined between the first and second end surfaces, a second stop provided adjacent to the first end and having a second height, wherein the first height increase along the length of the second polygonal shaped structure from the second end surface to the second stop and the
