Abstract
Embodiments relate to a vibratory separator that includes a basket having a basket magnet and a frame having an electromagnet. The electromagnet and the basket magnet are arranged to magnetically interact, and the interaction imparts a vibratory motion to the basket. Furthermore, embodiments relate to a method to operate a vibratory separator that includes depositing drilling material on the vibratory separator. The vibratory separator includes a basket having a basket magnet, a frame having an electromagnet, and a variable frequency drive operatively coupled to the electromagnet. Furthermore, the method includes instructing the variable frequency drive to control the electromagnet and imparting a vibratory motion to the basket with the electromagnet.
Claims20
A vibratory separator, comprising:
- a basket comprising a basket magnet;
- and
- a frame comprising an electromagnet;
- wherein the electromagnet and the basket magnet are arranged to magnetically interact;
- and
- wherein the interaction imparts a vibratory motion to the basket.
A method to operate a vibratory separator, comprising:
- depositing drilling material on the vibratory separator, the vibratory separator comprising:
- a basket comprising a basket magnet;
- a frame comprising an electromagnet;
- and
- a variable frequency drive operatively coupled to the electromagnet;
- instructing the variable frequency drive to control the electromagnet;
- and
- imparting a vibratory motion to the basket with the electromagnet.
The method of claim 19, wherein the vibratory profile defines a time sequence for energizing and de-energizing the electromagnet.
