The shale shaker is the first stage of solids control equipment in drilling purification system. It can remove cuttings above 75 μm brought from the drilling well to leave the liquid with smaller particles into the tanks below, which will flow into next grade solids control equipment for further treatment.
Structure of Shaker Deck
DUAL FUSE shale shakers is equipment with welded structure. Vibration motor & screen plate base are installed into screen basket with special parts. Screen basket is fixed on the adjustment beam. At each of the four vertexes of the screen basket there a vibration damping spring, which can prevent the adjoining parts and devices from being affected by the vibration. There are several shale shaker screen panels on screen basket, and they are fixed and adjusted by snap-on screw bolts and hooking tensioners so that the combined effect of horizontal and vertical supporting bars can provide enough strength for screens basket. And the panels are of an arched shape, thus making the panels more easily tensioned and more snugly inside the the frames, extending their service life as well as increasing the processing efficiency of particles.
AWD angle adjustment system
DUAL FUSE AWD (Adjustable While Drilling) angle adjustment system can raise or lower the end of screen basket while the machine is in operation. This part includes two vertical column assemblies that are connected on the upper beam assembly and are attached to the shaker base.
The mobile part of AWD consists of the lower beam, limiting device that controls vertical movement and screw rod that drives the upward and downward movement of the screen basket. Both ends of screw rod are hinged with the upper and lower beam assemblies respectively. Positive and negative rotating handles can make the screen basket move upward and downward respectively.
The screen basket angle of shale shaker can be arbitrarily adjusted within -1°~5° at an increment of 0.5°as required.
Feeder
The mud returned from the well or cuttings to be treated will flow into the shale shaker via the feeder. The feeders can be categorized into weir type, box type and bucket type.
The weir type and box type feeders are mainly used to buffer the flow rate of drilling fluids and evenly distribute the fluids onto the shale shaker screen to reduce the impact of drilling fluids on the screen, extend the service life of screen and improve the treatment effect.
Besides, the weir type feeder can also short-circuit the machine if necessary. The bucket type feeder is mainly used with the dryer shaker to collect and distribute cuttings.
The Economics of Linear Motion Shale Shaker
DUAL FUSE Linear Motion Shale Shaker is especially effective while drilling top-hole sections where heavy and high-volume solids are usually encountered. In these intervals, shakers may generate powerful G-forces and its effective vibrating motion can quickly remove the dense solids from screens and particles from wells.
