How to avoid the problem of slurries in oilfield shale shaker

How to avoid the problem of slurries in oilfield shale shaker

Page view

Everyone knows that the oilfield shale shaker is widely used. It screens materials by changing the trajectory of the screen surface. It can move to a certain position by moving to the entrance of the screen box under the action of the exciting force.

At this time, the main parameters of each point on the oilfield shale shaker have changed accordingly. The vertical amplitude and throwing index of each point are still large at the inlet end and small at the outlet end, but the linear inclination near the outlet end is inconsistent with other points on the screen surface. The linear trajectory inclines toward the entrance, where the solid particles are thrown back, so the solid phase of the oilfield shale shaker will accumulate at the exit. This indicates that the position of the line of action of the exciting force of the oilfield shale shaker has a limit. When designing a composite trajectory oilfield shale shaker, the adjustment of the line of action of the exciting force cannot exceed this limit.
 
The main parameters of each point on the screen surface when the line of action of the oilfield shale shaker excitation force moves towards the outlet of the screen box to a certain position. When the throwing index at the inlet end is the smallest, this is not conducive to the improvement of the solid-liquid separation efficiency, and the throwing index at the outlet end is the largest This will increase the amount of penetration and crushing of the separated solid phase particles. In addition, this situation will increase the flow of the oilfield shale shaker and increase the possibility of drilling fluid running out.
