New spinning quenching unit

Abstract

The invention provides a new spinning quenching unit, belonging to the technical field of chemical fiber processing. The quenching unit comprises two cabinet air flow rectifying devices, wherein each cabinet air flow rectifying device comprises a fine filter and an empty cavity; each fine filter comprises a perforated plate, a rectifying honeycomb plate and a protecting net in sequence from inside to outside; the lower ends of the two cabinet air flow rectifying devices are communicated with the empty cavities by blast pipes; deflector diffusion chambers are communicated below the empty cavities; horizontal drawer type coarse filters are arranged at the inlets of the deflector diffusion chambers and multilayer stainless steel screens and nonwovens are used for filtering; a computer is connected with an electric heating plate and air quantity regulating valves in a wired or wireless manner and controls the electric heating plate and the air quantity regulating valves; and the computer adjusted the temperature of the electric heating plate and the sizes of the air quantity regulating valves after processing the data measured by pressure and temperature detection devices. The quenching unit has the following beneficial effects: the speed of the quench air for cooling is uniform; the quenching unit can improve the quality of the formed fibers, is easy to dismantle and clean and has the functions of wind zone temperature control and adjustment of online processing technic of the computer.

Description

technical field [0001] The invention relates to a novel spinning side blowing device, which belongs to the technical field of chemical fiber processing. Background technique [0002] In the prior art, the thin stream of melt ejected from the micropores of the spinneret has to be cooled to a certain extent, and the cooling is uneven or not rapid, resulting in slow forming, and excessive wind speed is likely to cause broken ends and parallel pregnancy. There are also various impurities in the fiber, which can easily affect the quality of the fiber. The wind speed uniformity of side air cooling has a great influence on improving the fiber quality of silk, especially USTER CV%. Contents of the invention [0003] In view of the defects in the prior art, the purpose of the present invention is to provide a side blowing device, which can prevent impurities in the wind from mixing into the fibers, and can evenly cool the melt. [0004] In order to achieve the above-mentioned pur...
