This invention relates to an intelligent yarn production drawing frame and its usage method, belonging to the field of yarn processing technology. The drawing frame includes a drawing main unit, a trumpet-shaped guide, a coiler, a guide frame, and a can changing frame. It also includes multiple self-locking clamps detachably mounted on the guide frame and a can rotating base mounted on the can changing frame. The self-locking clamps include an inclined guide base and a wedge block slidably disposed therein. When the yarn passes through the guide base, the wedge block is driven upward by tension. When the tail yarn detaches, the wedge block slides down under gravity to lock the tail yarn, preventing high-speed whipping. The can rotating base includes a rotating disc and a flip-up feed tray. When the weight of the can tilts, the relative position of the coiler outlet and the can is automatically adjusted to ensure uniform yarn accumulation. This drawing frame effectively solves the problems of yarn breakage caused by tail yarn whipping, equipment entanglement, and uneven yarn accumulation caused by can tilting, thus improving production continuity and yarn quality.

This application discloses a rectifying electrostatic precipitator, belonging to the field of dust collector technology. By sequentially setting a guide layer, a mixing layer, and a stabilizing layer in the inlet conical section of the outer shell, multiple airfoil-shaped guide elements in the guide layer evenly distribute the airflow, directing it across the entire inlet conical section of the outer shell.

The stabilizing layer features a honeycomb open-cell design; the honeycomb structure effectively manages the airflow and stabilizes the velocity. Thus, the flue gas undergoes a three-stage process of "guidance-breakup-management" to achieve refined flow field treatment, improve velocity distribution uniformity, and reduce inlet local resistance.
