DUAL DECK VIBRATORY SEPARATOR

摘要

A dual deck vibratory separator is provided having an improved mud flow path that provides for higher flow capacities overall is provided. The shaker has a lighter basket possessing a full-size upper deck extending across the width and length of the basket. Operational efficiency and operability is improved with flow deflecting and energy absorbing plates disposed intermediate along the mud flow path. The screen assemblies are secured with improved wedges, improved wedge guides, screen cushions, and cushion stops on transverse structure members for longer screen and slide life. An optional vacuum tray on the finishing trays further enhances recovery of drilling fluid. Maintenance, when required, is improved through ease of upper screen removal for inspection and access. Inclined side windows on each side of the basket may provide cleaning and viewing access.

主权项

1. A dual deck vibratory shaker for separating solids from drilling mud, comprising:
a basket having a proximal end and a distal end; a first upper slide and first lower slide located on a first side wall of the basket, and a second upper slide and second lower slide located on a second side wall of the basket, the first and second upper slides running along a first plane and the first and second lower slides running along a second plane; an upper deck having a length, and extending from the proximal end to the distal end, comprising one or more removable upper screen assemblies on the first and second upper slides; a lower deck extending from the proximal end to the distal end, comprising one or more removable lower screen assemblies on the first and second lower slides; and a deflector plate extending from the first side wall and the second side wall underneath the first half of the length of the upper deck, or a part thereof, said deflector plate positioned to receive drilling fluid from the upper deck and to deliver the drilling fluid to the lower deck at the proximal end.
