ABSTRACT:
An apparatus for electrokinetically separating drilling mud into liquid and solid phases comprising a casing (1) having an inlet (2) for drolling mud and outlets (3,13) for separated phases thereof and accommodating electrodes connected to the negative terminal and to the positive terminal, respectively, of a d-c source (8). The electrode connected to the negative terminal of the d-c source (8) comprises a conveyor screw (4) which has a cylindrical portion (5) and an adjacent conical portion (6). The casing (1) functions as the electrode connected to the positive terminal of the d-c source (8) and has respective cylindrical (10a, 10b, 10c) and conical (11) portions. The outlet (13) for solid phase of drilling mud is provided at the end of the conical portion (11) of the casing (1). There is provided a receptacle (14) for collecting solid phase of drilling mud communicating with the outlet (13) for solid phase of drilling mud provided in the casing (1).
