Circular-blow cooling device

Abstract

The invention provides a circular-blow cooling device, which comprises a lower air chamber, an upper air chamber and a middle rectification layer. The middle rectification layer is positioned betweenthe lower air chamber and the upper air chamber, and the lower air chamber, the upper air chamber and the middle rectification layer are circular coaxially. The inner periphery of the upper air chamber is provided with a porous plate, and the upper air chamber is internally provided with a cooling oil passage which spirally surrounds the porous plate. Cooling air enters the lower air chamber and flows towards the middle rectification layer, the cooling air rectified by the middle rectification layer flows towards the upper air chamber, and after heat of the cooling air is taken away by coolingoil in the cooling oil passage, the cooling air is blown out through the porous plate. The circular-blow cooling device is simple in structure, easy in cleaning and maintenance, high in operating efficiency and capable of meeting the requirement of production of spun filaments with different properties.

Description

technical field [0001] The invention relates to the technical field of spinning and manufacturing, in particular to a cooling device for surrounding air blowing. Background technique [0002] For a long time, most of the production of chemical fiber filaments has been cooled by side blowing devices. As a result, energy consumption accounts for a large proportion of the cost of producing filaments. In the 21st century, with the increasing requirements for the performance and quality of chemical fibers, side blowing cooling devices can no longer meet the technological requirements of filament products, so higher cooling and blowing conditions are required. Through the continuous improvement of cooling devices, the development and application of a new type of chemical fiber cooling device - the surrounding air cooling device has been accelerated. The surrounding blower cooling device not only has the advantage that each bundle of filaments receives the wind evenly, but also ca...

Problems solved by technology

[0003] However, because the production environment temperature of melt spinning is often high, so that the temperature of the cooling air blown in from the outside is generally high, which not only is not conducive to the production of melt spinning, but also reduces the production efficiency, and the produced spinning The various properties of the yarn are the same, which cannot meet the needs of various customers, because the elasticity and toughness of the fiber yarn have a certain relationship with the cooling temperature, so if you want to produce spinning with different properties, you must replace the ring air cooling device
