Magnetic screen clamping
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.
1. A method for replacing a screen in a shale shaker comprising:
activating at least one decoupling apparatus wherein a magnetic clamping system comprises the at least one decoupling apparatus, and wherein the magnetic clamping system further comprises:
at least one screen comprising 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 comprises a first end and a second end; 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;
removing the at least one screen from the shale shaker;
deactivating the at least one decoupling apparatus, wherein deactivating the at least one decoupling apparatus comprises operating at least one handle disposed proximate to the perimeter of the shaker to reverse polarity of the at least one magnet, wherein the at least one handle comprises at least one shaft that extends horizontally therethrough for controlling an entire side of magnets; and
installing at least one replacement screen into the shale shaker.
2. The method of claim 1 , wherein the at least one screen comprises a first screen and a second screen, and wherein the at least one handle extends horizontally from proximate the first side of the first screen to proximate the second side of the second screen.
3. The method of claim 1 , further comprising preventing displacement of the at least one screen.
4. The method of claim 3 , wherein the preventing displacement of the at least one screen comprises holding the at least one screen with at least one stop track.
5. The method of claim 1 , further comprising aligning at least two magnets to form a magnetic circuit.
6. The method of claim 5 , further comprising achieving a magnetic field from the magnetic circuit.
7. The method of claim 5 , further comprising providing magnetic flux to a plurality of air gaps using a plurality of metal components.
8. The method of claim 7 , wherein the magnetic flux increases the magnetic hold between the at least one screen and the shale shaker.
9. The method of claim 1 , wherein reversing the polarity of the at least one magnet comprises moving the at least one magnets.
10. The method of claim 9 , wherein moving the at least one magnet comprises rotating the at least one magnet.
11. The method of claim 10 , wherein rotating the at least one magnet alters a magnetic circuit.
12. The method of claim 10 , rotating the at least one magnet breaks a magnetic circuit.
13. The method of claim 9 , wherein reversing the polarity of the at least one magnet comprises rotating the at least one magnet by approximately 180 degrees.
