International Classification:

B07B 1/46

US Classification:

209395, 209399, 209403, 209409

Abstract:

A magnetic claiming system for a shale shaker including at least one screen having at least two side ends extending between a first side and a second side and at least one attachment surface, at least one mating surface of a shale shaker configured to receive at least one screen, wherein the shale shaker has a first end and a second end, and at least on magnet disposed between the at least one screen and the shale shaker, wherein the at least one magnet is configured to magnetically couple the at least one screen to the shale shaker is disclosed. A method for replacing a screen in a shale shaker including activating at least one decoupling apparatus, wherein a magnetic clamping system includes the at least one decoupling apparatus, removing at least one screen from the shale shaker, deactivating the at least one coupling apparatus, and installing at least one screen into the shale shaker is also disclosed.

Abstract:

A magnetic clamping system for a shale shaker including at least one screen having at least two side ends extending between a first side and a second side and at least one attachment surface. The system further includes at least one mating surface of the shale shaker configured to receive the at least one screen, and at least one magnet disposed between the at least one screen and the shale shaker, wherein the at least one magnet is configured to magnetically couple the at least one screen directly to the shale shaker. Additionally, the system includes at least one decoupling apparatus, the decoupling apparatus having a handle disposed proximate a perimeter of a shale shaker, and at least one shaft that extends horizontally between the handle and one of the at least one magnet, wherein the handle is rotatable to reverse the polarity of the magnet.
