Efficient ultrahigh-molecular-weight polyethylene fiber drying device

Abstract

The invention relates to the technical field of polyethylene fiber production equipment, in particular to an efficient ultrahigh-molecular-weight polyethylene fiber drying device which comprises a chamber. The lower portion of the left wall of the chamber is penetratingly provided with a fiber inlet, the lower portion of the right wall of the chamber is penetratingly provided with a fiber outlet,a partition plate with vent holes is arranged in the chamber, and circulating fans are arranged between the partition plate and the inner bottom of the chamber. Heating tubes are arranged on the top face of the partition plate, lower guide rollers are arranged above the partition plate, upper guide rollers are arranged between the lower guide rollers and the inner top face of the chamber, a gap isreserved between every two adjacent upper guide rollers, and the lower guide rollers are positioned below the gaps. Flow guide plates are arranged on the top face of the chamber, and an exhaust fan is arranged on the top face of the chamber. By the partition plate, broken polyethylene fibers are prevented from falling into the circulating fans; heat utilization efficiency is improved by the circulating fans; by corresponding arrangement of the heating tubes and the circulating fans, accumulation of heat at the partition plate can be prevented; by the flow guide plates, damp hot air can be guided to the exhaust fan, and condensate water can be guided to flow down along the inner wall of the chamber by the tangential flow guide plates.

Description

technical field [0001] The invention relates to the technical field of polyethylene fiber production equipment, in particular to a drying device for efficiently drying ultra-high molecular weight polyethylene filaments. Background technique [0002] At present, the drying oven widely used in the production of polyethylene fiber on the market mainly uses an oven to dry the material, and the air is heated and introduced into the oven for drying. This method has poor uniformity in the drying process, and the outside of the oven There is no insulation layer, resulting in more heat loss. Another way is to set the heating wire on the outside of the drying oven, and increase the temperature in the oven by heating the heating wire, so as to achieve the purpose of drying. However, due to the distance between the heating wire and the inner wall of the oven Recently, the heat generated is sharply concentrated on the inner wall of the oven. If the temperature is not well controlled, the...
