The shale shaker is the first stage of solids control equipment in drilling purification system on oil or gas drilling operation. It can remove cuttings above 75μm 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 to be treated.The shale shaker can be also called as drilling mud shale shaker or oilfield drilling shale shaker.
The Economy of Drilling Mud Shale Shaker
KOSUN drilling mud 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.
Drilling Mud Shale Shaker Features:
1. G-forces linear motion up to 7.4 G(adjustable depending on the situation)
2. Hi-speed conveyance of cuttings
3. Higher shaker-fluids capacity
4. Able to process heavier solids loads
5. Enhances cuttings processing volume
6. AWD device from -1°~5°
7. Single side screens tension system to easily change the screens
8. Shaker feeder can be weir type and header box
9. Hook-strip screens can be PMD and PWP screens
Structure of Drilling Mud Shale Shaker Deck
KOSUN patented oilfield drilling shale shaker is an solids control 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 put a vibration damping spring,which can prevent the adjoining parts and devices from being affected by the vibration.There are several 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 may provide enough strength for screens basket.And the panels appear in an arched shape,thus making the panels more easily tensioned and more intimately connected with the frames,blessing them with longer service life as well as increasing the processing efficiency of particles.
AWD Angle Adjustment System Of KOSUN Drilling Shale Shaker
Kosun patented AWD angle adjustment system can raise or lower the end of screen basket while the drilling shale shaker is working.This part includes two vertical column assemblies that are connected on the upper beam assembly and are attached to the drilling mud 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 drilling mud shale shaker can be arbitrarily adjusted within -1°~5° at an increment of 0.5°as required.
The mud returned from the well or cuttings to be treated will flow into the drilling mud 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 fluid and evenly distribute the fluid onto the screen to reduce the impact of drilling fluid 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.
