Abstract
An apparatus includes a vibratory separator with a top deck, a middle deck, and a bottom deck, and a collection trough coupled to at least one of the top deck, the middle deck, and the bottom deck. The collection trough includes a collection container having an inlet configured to receive a material retained on the at least one of the top deck, the middle deck, and the bottom deck, and a sloped surface configured to guide the material from the inlet to an outlet of the collection container, and a pressure differential generator disposed proximate the outlet of the collection container.
Claims18
An apparatus comprising:
- a vibratory separator having a top deck, a middle deck, and a bottom deck;
- and
- a collection trough coupled to at least one of the top deck, the middle deck, and the bottom deck, the collection trough comprising:
- a collection container having an inlet configured to receive a material retained on the at least one of the top deck, the middle deck, and the bottom deck and a sloped surface configured to guide the material from the inlet to an outlet of the collection container;
- and
- a pressure differential generator disposed proximate the outlet of the collection container.
An apparatus comprising:
- a vibratory separation having deck with a screening surface;
- and
- a collection trough coupled to the deck, the collection trough comprising:
- a hopper having an inlet and an outlet;
- a conduit coupled to the outlet of the hopper, and
- an eductor coupled to the conduit.
A method comprising:
- providing a flow of drilling fluid from a wellbore to a screening deck of a vibratory separator;
- separating the drilling fluid into a filtrate and an overflow;
- directing the overflow to a hopper of a collection trough proximal to the screening deck;
- and
- creating a pressure differential proximate an outlet of the hopper, thereby flowing the overflow from the collection trough through an outlet conduit coupled to the outlet.
