Circumferential blowing type circular spandex spinning tunnel

Abstract

The invention relates to a circumferential blowing type circular spandex spinning channel which comprises a cylindrical channel body (4), a spinneret plate assembly (3), an annular rectifier (2), a hot airflow inlet (1), a flow guide column (6) and a static pressure chamber (7), wherein the flow guide column (6) is arranged in the middle of the upper part of the cylindrical channel body (4), the static pressure chamber (7) is arranged at the upper part of the cylindrical channel body (4) and comprises a static pressure chamber cylinder (7.1), a locating support (7.2) and a metal wire mesh sintering felt wind-equaling device (7.3), the static pressure chamber cylinder (7.1) is arranged in the cylindrical channel body (4), the metal wire mesh sintering felt wind-equaling device (7.3) is arranged in the static pressure chamber cylinder (7.1) and arranged below the annular rectifier (2), and the locating support (7.2) is arranged at the bottom of the metal wire mesh sintering felt wind-equaling device (7.3) and is fixedly connected with the static pressure chamber cylinder (7.1). The circumferential blowing type circular spandex spinning channel has large air-blowing area and large air volume.

Description

technical field [0001] The invention relates to a circular spandex spinning tunnel. It belongs to the technical field of spandex spinning equipment. Background technique [0002] The spandex spinning tunnel is mainly used in the air distribution inside the spandex spinning equipment, the arrangement of the spandex tow and the heat tracing system. Before the present invention was made, in the spandex spinning process, the top circular blowing was usually used, the blowing area was small, the air volume was small, and the solvent could not be effectively and quickly volatilized. As a result, the number of spinning heads in the circular tunnel is small (less than 24 heads), and the production capacity is low, which cannot meet the production needs of multiple heads (36 heads, 48 ​​heads, 64 heads), resulting in high energy consumption and high production costs. Spandex spinning Low speed and high solvent carryover. Contents of the invention [0003] The object of the prese...
