Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, specifically to a novel structure for a rotor spinning machine's exhaust duct. Background Technology

[0002] Because rotor spinning machines have long carriages, the currently used carriages are all around 70 meters long. Also, because the exhaust fan of the rotor spinning machine is arranged at the front or rear of the carriage, there will be a pressure difference between the end near the exhaust and the end far away during operation, and the pressure drop will be greater the farther away from the exhaust.

[0003] Existing rotor spinning machines have two types of impurity removal structures: single-sided impurity removal and double-sided impurity removal.

[0004] Single-sided exhaust ducts are typically located at the rear of the vehicle. The airflow in the duct flows directly from the front to the rear of the vehicle, resulting in the lowest negative pressure at the point furthest from the rear. Significant pressure differences in the exhaust ducts between spinning units can lead to variations in yarn quality. Furthermore, maintaining the lowest negative pressure at the exhaust duct point during spinning requires increasing the fan power, thus increasing energy consumption. Figure 1 As shown.

[0005] Dual-side exhaust systems have exhaust mechanisms at both the front and rear of the vehicle, which can effectively solve the pressure difference problem caused by single-side exhaust systems, but the problem is that energy consumption increases significantly. Utility Model Content

Two rows of plug holes are symmetrically opened at one end of each discharge pipe, and several plug holes are evenly arranged in each row. One end of the arc-shaped connecting plate is symmetrically and fixedly connected to the discharge branch pipes of the corresponding plug holes in two rows. One end of the discharge branch pipe passes through the side wall of the arc-shaped connecting plate and is fixedly sleeved with a rubber sealing sleeve.
