This utility model discloses a dedicated hydrocyclone structure for mud separation, relating to the technical field of hydrocyclone structure. The dedicated hydrocyclone structure for mud separation includes a mud hydrocyclone with a discharge control device installed at its bottom. The dual overflow ports on the upper cylinder enable graded separation of particles of different sizes in the mud. The light phase overflow port mainly discharges the clean liquid after thorough separation, while the intermediate phase overflow port collects liquid containing a small amount of fine particles. This liquid can be either returned to the feed end for secondary separation or transported to a specific processing stage, depending on actual production needs, thereby maximizing resource utilization.
