Shale shaker is the first stage purification solids control equipment in oil drilling. Its function is to remove large solids in drilling fluids. Under the action of the shale shaker, drilling operating keep maximum high porosity, high screening efficiency, large treatment capacity, easy to replace screen, reduce cost. Shale shaker with larger screen surface and treatment capacity can meet requirement of manufacturing at site.
Drilling mud shale shaker is mainly composed of the following components.
1. Buffer slot
Drilling fluid returning to ground from the bottom of the well flow into buffer slot of shale shaker, decreasing drilling mud speed, and make the drilling liquid flow into the screen evenly and slowly.
2. Screen box
It is used to tight shale shaker screen, support vibration exciter, and transfer continuous vibration from vibration exciter to screen, so as to achieve the purpose of screening
3. Shale shaker screen
It used to remove solid, recover important part of the drilling fluid. Shale shaker removing solids size completely depend on screen hole mesh size.
4. Vibration exciter
It is the power source of the screen box vibration. Producing periodic exciting force make screen box continuous and periodic vibration.
5. Damper spring
To support the screen box and a vibration exciter and ensure enough space with vibration sieve box. At the same time, as the auxiliary to meet screen box vibration requirements, and buffering and reducing dynamic load on base and a drilling fluid tank.
6. Base
Support all the parts for convenient installation and transportation.
