AI Technical Summary
The fixed inlet of existing drilling fluid separation devices leads to the accumulation of waste residue, which affects the separation effect.
By setting a reciprocating threaded screw and screw nut mechanism, the mounting base and sleeve are driven to move back and forth, so that the liquid inlet hose is evenly distributed on the coarse filter screen. The high-efficiency filtration mechanism uses a cam to drive the filter screen to vibrate intermittently to prevent clogging.
This achieves uniform distribution of drilling fluid and vibration of the filter screen, avoiding waste accumulation and improving the filtration effect of the separation device.
