Shale shaker is the primary solids control equipment that removes drill cuttings from the drilling fluid while circulating and drilling. There are many different designs and research into the best design is constantly ongoing since solids control is vital in keeping down costs associated with the drilling fluid.
In oil & gas drilling solids control industry, linear motion shale shaker are widely used for drilling mud purification system.
KOSUN Shale Shaker
Shale shakers consist of the following main parts:
Sifting Bed Structure:
KOSUN screen basket is of weld components and vibration motor & screen plate base are installed on screen box by parts. Screen basket locates on the adjustment beam and there are bumper springs in four corners near the screen box, which can avoid the screen basket vibrating effect on parts & devices in the neighborhood. There are three or four screen panels on the enough strength for screen basket.
The middle part of screen basket is higher than two sides transversely and the bulging arch the screen can be tensioned more easily and the screen life and efficiency of removing solids particles can be improved as the work proceeds.
AWD angle adjustment system:
The angle adjustment system while drilling, AWD for short, can raise or lower the screen basket end during the work. This part includes two vertical column assemblies that are connected on the upper column assembly and are attached to the shaker base.
The movable part of AWD consists of the lower column,limit device that controls vertical movement and hydro jack that drives the upward & downward movement of the screen basket. The fixed ends of jack are connected in upper column assemblies and the movable piston bar is fixed in the lower column assembly. Reciprocately pulling the operating grip of the hand pump or starting the oil return valve of the hand pump can make the screen basket move upward and downward respectively. The screen basket can be adjusted within -1°~+5°. Fix and lock the elevator with clamp pin at the suitable angle, which can reduce the attack on the hydraulic pump when the basket is running at this angle.
Feeder:
The mud treated by other equipment or mud that returns from well will flow into the shale shaker through feeder tanks which has a buffer effect on the drilling fluid and can make the mud flow onto the screen equably. This can reduce the mud attack to the screen and increase screen work life and mud treatment efficiency. Meanwhile there is a square cover on the tank top and from here we can test the mud performance.
Vibration Motor:
It boasts of the features of stronger vibrating strength, higher reliability and easier maintenance. The exciting force is generated by eccentric rotor and the exciting force of single motor can reach 38kN. Suitable ambient temperature is : -40℃~150℃.
