Abstract

Disclosed embodiments include a removable support structure for a vibratory screening machine. The removable support structure is a single structure including one or more of plastic, metal, and composite materials and may be configured to provide mechanical support to one or more screening assemblies of the vibratory screening machine. The removable support structure may further be configured to be removably fastened to the vibratory screening machine. The removable support structure may be a single thermoplastic injection molded piece or may be a single injection molded piece that includes nylon, carbon, and graphite. The removable support structure may have a concave shape that is configured to mechanically support a screening assembly held under compression or may have a convex shape that is configured to mechanically support a screening assembly held under tension. A disclosed wear protective covering, made of a flexible material, provides wear protection to the removable support structure.

First claim

What is claimed is:

1. A vibratory screening machine, comprising:
one or more screening assemblies; and
a plurality of injection molded removable support structures configured to provide mechanical support to the one or more screening assemblies; and
a plurality of removable wear protective covers configured to be installed on respective support structures and to provide wear and abrasion resistance to the removable support structures.

2. The vibratory screening machine of claim 1 , wherein the removable support structures include one or more of plastic, metal, and composite materials.

3. The vibratory screening machine of claim 1 , wherein the removable support structures include nylon.

4. The vibratory screening machine of claim 3 , wherein the removable support structures include fiber-reinforced nylon.

5. The vibratory screening machine of claim 4 , wherein the removable support structures include carbon or graphite.

6. The vibratory screening machine of claim 1 , wherein the removable support structures have a concave shape and are configured to mechanically support screening assemblies held under compression.

7. The vibratory screening machine of claim 1 , wherein the removable support structures have a convex shape and are configured to mechanically support screening assemblies held under tension.

8. The vibratory screening machine of claim 1 , wherein the removable support structures are configured to be removably fastened to the screening machine.

9. The vibratory screening machine of claim 1 , wherein the wear protective covering structures include thermoplastic polyurethane (TPU).

10. The vibratory screening machine of claim 9 , wherein wear protective covering structures have a shape that conforms to a shape of the removable support structures.

11. The vibratory screening machine of claim 10 , wherein the wear protective covering and the removable support structures each have a tapered or pyramidal cross-sectional shape.

12. The vibratory screening machine of claim 1 , wherein the wear protective covering structures are made of a flexible material that provides scratch resistance, tear resistance, and puncture resistance.

13. A removable support structure for a vibratory screening machine, comprising:
a single structure including one or more of plastic, metal, and composite materials, wherein the removable support structure is a single injection molded piece, and
wherein the removable support structure is configured to be removably fastened to the vibratory screening machine and to provide mechanical support to one or more screening assemblies of the vibratory screening machine.

14. The removable support structure of claim 13 , further comprising a thermoplastic injection molded material.

15. The removable support structure of claim 13 , further comprising one or more of nylon, carbon, and graphite.

16. The removable support structure of claim 13 , further comprising a concave shape that is configured to mechanically support a screening assembly held under compression.

17. The removable support structure of claim 13 , further comprising a convex shape that is configured to mechanically support a screening assembly held under tension.

18. A method of fabricating a removable support structure for a vibratory screening machine, the method comprising:
injection molding the removable support structure as a single structure,
wherein the removable support structure is configured to be removably fastened to the vibratory screening machine and to provide mechanical support to one or more screening assemblies of the vibratory screening machine.

19. The method of claim 18 , wherein the removable support structure further comprises one or more of thermoplastic, nylon, carbon, and graphite.

20. The method of claim 18 , wherein the removable support structure comprising a concave or convex shape that is configured to mechanically support a screening assembly held under compression or under tension, respectively.

21. A removable support structure for a vibratory screening machine, comprising:
a single support structure including one or more of plastic, metal, and composite materials; and
a wear protective covering,
wherein the removable support structure is configured to be removably fastened to the vibratory screening machine and to provide mechanical support to one or more screening assemblies of the vibratory screening machine, and
wherein the wear protective covering provides wear resistance to the support structure and is configured to be removably installed on the support structure.

22. The support structure of claim 21 , wherein the removable support structure further comprises one or more of thermoplastic, nylon, carbon, and graphite.

23. The support structure of claim 22 , wherein the removable support structure further comprises glass-fiber or carbon-fiber reinforced nylon.

24. The support structure of claim 21 , wherein the removable support structure comprising a concave or convex shape that is configured to mechanically support a screening assembly held under compression or under tension, respectively.

25. The support structure of claim 22 , wherein the wherein the wear protective covering further comprises a hydrophobic abrasion resistant material.

26. The support structure of claim 22 , wherein the wherein the wear protective covering further include TPU.

27. The support structure of claim 22 , wherein the wherein the wear protective covering is configured to snap onto the support structure and closely conform to an external shape of the support structure.

28. A method of screening a material, the method comprising:
installing removable support structures on a vibratory screening machine; wherein each removable support structure is a single injection molded piece;
installing wear protective coverings on the support structures;
mounting a screening assembly on the vibratory screening machine so that the screening assembly is supported by the covered removable support structures; and
screening the material.

29. The method of claim 28 , wherein the removable support structure further comprises one or more of thermoplastic, nylon, carbon, and graphite.

30. The method of claim 29 , wherein the removable support structure further comprises glass-fiber or carbon-fiber reinforced nylon.

31. The method of claim 28 , wherein the removable support structure comprising a concave or convex shape that is configured to mechanically support a screening assembly held under compression or under tension, respectively.

32. The method of claim 28 , wherein the wherein the wear protective covering further comprises a hydrophobic abrasion resistant material.

33. The support structure of claim 32 , wherein the wherein the wear protective covering further include TPU.

34. The support structure of claim 28 , wherein the wherein the wear protective covering is configured to snap onto the support structure and closely conform to an external shape of the support structure.
