Trenchless HDD Desander and Desilter , Hydrocyclone Desander Unit for Mud Slurry Recycling

Brief Introduction

TRCS series desander overcomes shortcomings of the original sand removal process. The hydrocyclone of desander is provided with a rotating component, and its cylindrical wall is with a separation window. The upper cylinder wall of the rotating member, a set of tapered grooves and liquid inlet pipe constitute drilling fluid lifting component. Impeller of desander is set at the interior of the component, and sand regulator controls the amount of sand.

Drilling fluid enters the rotating component from the inlet pipe, after centrifugal rotation of the blade, the liquid rises to the separation window when the sand is separated from the drilling fluid, the sand is discharged into the sanding cone through the separation window. The separated drilling fluid enters the lifting component, and drilling fluid is discharged into the drilling tank by the drain of the conical groove. The sand in the cone is discharged from the sand outlet controlled by the sand regulator device and the separation is completed.

Operation Mechanism

Desander includes two 12-inch(305-mm) diameter polyurethane hydroclones slant mounted over the shaker. Each desander clone includes four replaceable wear resistant polyurethane sections that are joined together with quick release stainless steel clamps. The desander is furnished with an 8-inch(203-mm) diameter feed manifold and a 10-inch (254-mm) diameter discharge manifold and a 0-60 psi (4.1-bar) pressure gauge. The desander also includes a solids discharge trough to distribute the hydroclone underflow evenly onto the screening surface.
