Heat energy recycling system based on spandex spinning and application method thereof

Abstract

The invention discloses a heat energy recycling system based on spandex spinning. The system comprises a bottom plate, a bracket and a spinning channel, wherein the bracket is fixed at the top of thebottom plate, the spinning channel is fixed at the top of the bracket, a heat recovery mechanism is arranged at the top of the bracket, a filtering speed regulating mechanism is arranged at the top ofthe bottom plate, a solvent recovery mechanism is further arranged at the top of the bottom plate, a vacuum heat collecting pipe is fixed at the top of the bracket, and an air inlet of the vacuum heat collecting pipe communicates with an air outlet of the spinning channel through an air inlet pipe. The invention relates to the technical field of spandex spinning. According to the heat energy recycling system based on spandex spinning and an application method thereof, heat is conveniently collected through the vacuum heat collecting pipe, the heat is conveniently transferred to water throughthe arrangement of a heat conduction arc-shaped buckle plate and a coil pipe, the heat energy is recycled, a fan-shaped through groove is conveniently blocked through the arrangement of an adjusting motor, an adjusting shaft, a lantern ring and a fan-shaped baffle, the air inlet rate is further conveniently adjusted, and the use limitation is small.

Description

technical field [0001] The invention relates to the technical field of spandex spinning, in particular to a heat energy recovery and reuse system based on spandex spinning and an application method thereof. Background technique [0002] Spandex is the abbreviation of polyurethane fiber, which is a kind of elastic fiber. Spandex is generally composed of multiple filaments. During the production process of spandex spinning, the mass content of polymer (polyurethane) in the spinning dope entering the spinning assembly is 35%, and the remaining 65% is the solvent DMAC (N, N-di methylacetamide). After the spinning stock solution enters the upper spinning channel through the spinneret, the solvent DMAC in the stock solution needs to be quickly volatilized, and the remaining polymer is solidified and formed and undergoes processes such as the middle channel, the lower channel, false twisting, oiling, and winding. Finally made spandex fiber. [0003] According to the patent No. C...
