The invention discloses a circular treatment device and method based on waste
drilling fluid recovery, and belongs to the technical field of waste
drilling fluid treatment.The circular treatment device based on waste
drilling fluid recovery comprises a treatment frame with the interior of a hollow structure, and the two sides, the top and the bottom of the treatment frame are in an open state; twisting assemblies are installed on the two sides of the interior of the treatment frame and used for dynamically stripping viscoelastic
solid-phase inclusions in the waste drilling fluid, and flexible friction stripping assemblies rotationally connected with the twisting assemblies are arranged in the treatment frame and used for adhering, stretching and stripping the viscoelastic inclusions. Organ covers in sliding connection with the
processing frame are mounted at the top and the bottom of the flexible friction stripping
assembly. The flexible friction stripping
assembly and the twisting
assembly are adopted, the characteristics of
viscoelastic substances are utilized, inclusion can be actively and efficiently grabbed out of liquid flow, stripping is thorough, and the wrapped useful
liquid phase is effectively released.
