摘要

APPARATUS FOR ELECTROKINETICALLY SEPARATING DRILLING MUD An apparatus for electrokinetically separating drilling mud into liquid and solid phases comprising a casing having an inlet for drilling mud and outlets for separated phases thereof and accommodating electrodes connected to the negative terminal and to the positive terminal, respectively, of a d-c source. The electrode connected to the negative terminal of the d-c source comprises a conveyor screw which has a cylindrical portion and an adjacent conical portion and is installed in the casing which functions as the electrode connected to the positive terminal and has respective cylindrical and conical portions. The outlet for solid phase of drilling mud is provided at the end of the conical portion of the casing, and there is provided a receptacle for collecting solid phase of drilling mud communicating with the outlet for solid phase of drilling mud provided in the casing, which is arranged at the end of the conical portion of the casing. The apparatus makes it possible to substantially completely separate from drilling mud the solid phase rich in chemical reagents for subsequent utilization.
