AI Technical Summary

Technical Problem

Existing fiber stream dedusting devices in spinning mills are inefficient, allowing dust to remain in the fiber stream, leading to rotor clogging and yarn defects such as moiré effects due to low settling velocity of dust particles.

Method used

A device with a helical fiber transport system and diametrically opposed dust filter sections, utilizing negative pressure to enhance dust removal efficiency by guiding fibers past filter sections from multiple orientations, incorporating multiple filter types and adjustable filter parameters.

Benefits of technology

Significantly improves dust removal efficiency by ensuring fibers are dusted from different sides, reducing rotor clogging and enhancing yarn quality by effectively capturing dust particles.

Abstract

The invention relates to a device in the spinning preparation for dedusting a fiber stream (F), comprising: an inlet (13) through which the fiber stream (F) can be introduced into the device (1); and an outlet (33) through which the fiber stream (F) can be discharged from the device (1);and a first cleaning channel (14) which fluidically connects the outlet (33) to the inlet (13) and extends along a first longitudinal axis (L_14) and is bounded by a tubular first wall (15), and a fiber transport device which is configured to convey the fiber stream (F) in the first cleaning channel (14) helically around the first longitudinal axis (L_14) in a first transport direction, wherein a first section of the first wall (15) is configured as a first dust filter section (16), and a second section of the first wall (15) is configured as a second dust filter section (17), and the first section and the second section are arranged diametrically opposite each other with respect to the first longitudinal axis (L_14).
