Abstract

Embodiments of the present disclosure provide for systems, apparatuses, and methods of securing screen assemblies. Embodiments include a system having a compression assembly with a compression pin and a pin assembly having a pin. The compression assembly may be attached to a first wall member of a vibratory screening machine and the pin assembly may be attached to a second wall member of the vibratory screening machine opposite the first wall member such that the compression assembly is configured to assert a force against a first side portion of a screen assembly and drive a second side portion of the screen assembly against the pin of the pin assembly. The pin assembly may include a pin that is internally or externally mounted and that is adjustable and/or replaceable.

First claim

What is claimed is:

1. A method for securing a screen assembly, comprising:
placing the screen assembly on a vibratory screening machine; and
securing the screen assembly to the vibratory screening machine by activating a compression assembly, wherein the compression assembly drives a first member against the screen assembly and pushes the screen assembly into a second member, wherein the second member is a pin assembly that includes a pin and is fixed with respect to the vibratory screening machine and is located opposite the first member.

2. The method of claim 1 , wherein the first and second members each include pins.

3. The method of claim 1 , wherein the compression assembly is attached to a first wall member of the vibratory screening machine and the second member is attached to a second wall member of the vibratory screening machine opposite the first wall member.

4. The method of claim 3 , wherein an end of the second member protrudes through the second wall member and into the vibratory screening machine.

5. The method of claim 3 , wherein the second member includes a mounting block that is fixed to the second wall member.

6. The method of claim 5 , wherein the pin of the pin assembly is located within the mounting block.

7. The method of claim 6 , wherein the pin of the pin assembly is at least one of removable and replaceable.

8. The method of claim 1 , wherein the pin has an end face that engages the screen assembly and is shaped to push the screen assembly in a desired direction or at a desired angle.

9. A system for attaching a screen assembly to a vibratory screening machine, comprising:
a compression assembly attached to and extending through a first external wall of the vibratory screening machine, the compression assembly including a first member; and
a pin assembly fixed to and extending through a second wall of the vibratory screening machine that opposes the first wall, the pin assembly including a second member and a pin;
wherein the screen assembly is attached to the vibratory screening machine by activating the compression assembly which drives the first member through the first wall and against the screen assembly to push the screen assembly into the second member.

10. The system of claim 9 , wherein the first and second members each include pins.

11. The system of claim 9 , wherein the pin assembly includes a mounting block that is fixed to the second wall.

12. The system of claim 11 , wherein the pin of the pin assembly is located within the mounting block.

13. The system of claim 12 , wherein the pin of the pin assembly is at least one of removable and replaceable.

14. The system of claim 9 , wherein the pin of the pin assembly has an end face that engages the screen assembly and is shaped to push the screen assembly in a desired direction or at a desired angle.

15. A system for applying a compressive force to a screen assembly on a screening machine, comprising:
a compression assembly that includes a handle, a mounting bracket attached to a first wall of the screening machine, and a compression pin extending through the first wall to contact the screen assembly; and
a pin assembly that includes a mounting block fixed to a second wall of the screening machine, and further includes a pin located within the mounting block and extending through the second wall;
wherein the compression pin pushes the screen assembly into contact with the pin of the pin assembly in response to rotation of the handle.

16. The system of claim 15 , wherein the pin of the pin assembly is at least one of removable and replaceable.

17. The system of claim 15 , wherein the pin of the pin assembly includes threads that correspond to threads on the mounting block.

18. The system of claim 15 , wherein the handle is removable from the compression assembly.

19. The system of claim 15 , wherein the compression assembly further includes a latch assembly that locks the compression assembly into a compressed position with the compression pin in contact with the screen assembly.
