Blown air rectifying device of chemical fiber spinning equipment

Abstract

The invention discloses a blown air rectifying device of chemical fiber spinning equipment, which is mounted at the air outlet of an air blowing device of chemical fiber spinning equipment. The blown air rectifying device comprises the components of a perforated plate, a filtering net, a honeycomb plate and an air uniforming net; wherein the perforated plate, the filtering net, the honeycomb plate and the air uniforming net are successively arranged from bottom to top. A plurality of small holes are uniformly distributed on the perforated plate. The filtering net is clamped between an upper flange and a lower flange and is fixed on the perforated plate. A honeycomb plate frame is arranged outside the honeycomb plate and the air uniforming net. The lower flange is fixedly connected with the honeycomb plate frame. The blown air rectifying device of the chemical fiber spinning equipment is advantageous in that the blown air rectifying device is mounted at the outlet of the air blowing device; uniform air pressure and uniform and stable air speed of outgoing air can be realized; balanced air blowing in cooling spun filament can be ensured; and furthermore uneven wind velocity rate is lower than 10%.

Description

technical field [0001] The invention belongs to the field of spinning equipment, in particular to an air equalizing and rectifying device used on a blowing device of chemical fiber spinning equipment. Background technique [0002] In the chemical fiber spinning process, the effect of spinning cooling directly affects the quality of the fiber. In the current chemical fiber spinning equipment, a blowing device is usually installed under the spinneret, and the chemical fiber is blown and cooled by side blowing or surrounding blowing, and then the chemical fiber filaments with specific requirements are obtained. Although the blowing device in the prior art is even and stable, the wind speed is relatively small, the wind speed unevenness is greater than 15%, and the energy consumption is large, which cannot meet the forming and cooling conditions of various differentiated fibers. The main factor affecting the blowing unevenness of the spinning cooling and blowing device is the r...
