Abstract

The invention relates to a recovery device, in particular to a recovery device for an ultra-high molecular weight polyethylene fiber pre-drawing hot water solvent. The invention mainly provides the recovery device for the ultra-high molecular weight polyethylene fiber pre-drawing hot water solvent, which can be used for recovering the solvent and carrying out a secondary reaction without excessive manual operation and is convenient for observing the recovery amount of the solvent. The recovery device for the ultra-high molecular weight polyethylene fiber pre-drawing hot water solvent comprises a shell, a material box, a pressure mechanism and a display mechanism; the material box is arranged at the top of the shell; the pressure mechanism is arranged at the top of the material box; and the display mechanism capable of observing the liquid level value of the collected solvent is arranged on one side of the material box. The residual solvent can flow into a first guide pipe, and along with accumulation of the solvent in the first guide pipe, the material box is driven by a pressing plate to be opened, so that the subsequent recovery process is facilitated.

Description

technical field [0001] The invention relates to a recovery device, in particular to a recovery device for pre-drawing hot water solvent of ultra-high molecular weight polyethylene fiber. Background technique [0002] Ultra-high molecular weight polyethylene fiber has the characteristics of high strength, high modulus, and low density, and is often used in modern war and defense equipment, aerospace and aviation, and civilian fields. [0003] At present, ultra-high molecular weight polyethylene fibers are mostly produced by gel spinning ultra-high heat stretching process, mainly using white mineral oil solvent to dissolve ultra-high molecular weight polyethylene to make spinning solution, and the remaining reaction solvent will remain in the container , due to its recyclability for secondary utilization, the reaction solvent will be recovered during the production process. After recovery, a certain amount of reaction solvent can be taken out, and the reaction solvent can be s...
