While in complete steps of solids control, mud cleaner is the combination of second and third steps of the mud processing steps. It is the combination of desander hydrocyclone, desilter hydrocyclone and the shale shaker for treating process of the drilling fluid. The main structure of the mud cleaner is define in two parts. The upper parts are desander hydrocyclones and desilter hydrocyclones that shoot our solids to bottom parts of mud cleaner which is shale shaker. This combination have the advantage of space saving and operation cost saving.
Drilling fluid mud cleaner is a filtering equipment of solid control purification system. Mud cleaner is composed by inlet, outlet pipe and hydrocyclones. Hydrocyclone is made of PVC, upper cone, and under cone. The overflow line, inlet line and outlet line is fixed by the clamp. The bottom inject outlet can be adjusted and changed it according to drilling cutting in drilling fluid. When adjust the bottom flow mouth, only need screw out the adjusting spray result. Screw on the adjusting spray after changed the bottom flow sand removal exit. The both side of desander are equipped the inlet mouth, when choose the side, the other side need to cover off by blanking cover.
Drilling mud enter into the hydrocyclone inner wall from the feeding of the hyrocyclone mouth, then tangential enter into hydrocyclone cyliner with high spinning speed will produce the enormous centrifugal force field, the light drilling mud spin upper from the central low pressure areas, and discharged to drilling fluid circulating tank from the overflow exit. The heavy solid phase particles are throw to the cylinder wall by the centrifugal force, which is spiral sinking under the action of the thrust drilling fluid downward spiral and discharged from the bottom flow mouth, the flow to the screen surface.
