Vertical type three-dimensional polyester short fiber relaxation heat-setting machine

Abstract

A vertical type three-dimensional polyester short fiber relaxation heat-setting machine is a vertical tower. The upper section is a dehumidification section, and the lower section is a setting section; the tower top end, namely, the dehumidification section top end is internally provided with a fiber-spreading machine, a fiber inlet is connected with the top end, a cotton-suction machine and a centrifugal fan are arranged above the fiber inlet, a high pressure fan, a moist air discharge valve and a heater are sequentially arranged between a tower top air outlet and a dividing line of the upper section and the lower section, a wind blockage valve is arranged at an outlet formed in the bottom of the setting section, a cooling chain plate is arranged below the bottom of the setting section, and multiple layers of cotton leveling devices are arranged in the dehumidification section and the setting section at intervals. The vertical type three-dimensional polyester short fiber relaxation heat-setting machine has the following advantages that energy conservation is conducted, heat preservation of a drying tower and a setting tower is performed well, and less heat is dissipated; the failure rate is low, the phenomena of air leakage, cotton leakage, chain plate clamping and the like do not exist, and maintenance is convenient; the technology is more reasonable; technology adjustment is more convenient, and the temperature of the drying tower and the setting tower can be high; space is saved, and a horizontal setting machine with the yield of 20,000 ton / year needs 300 square meters.

Description

technical field [0001] The invention relates to a setting equipment in the production process of polyester three-dimensional short fibers, in particular to a vertical three-dimensional polyester short fiber relaxation heat setting machine. Background technique [0002] In recent years, polyester fiber has developed rapidly. This fiber is very popular among users due to its excellent bulk resilience, light weight and good warmth retention. [0003] The three-dimensional polyester staple fiber must be treated by a relaxation heat setting machine to obtain stable structure and performance. Obviously, the relaxation heat setting machine is a very important process in the post-processing of polyester hollow fibers. Room temperature, setting time, wind speed on the chain plate and cooling at the outlet will determine the quality of the final product. The existing slack heat setting machine dehumidification, setting, and cooling three processes are placed flat on the ground in tur...

AI Technical Summary

Problems solved by technology

The existing slack heat setting machine dehumidification, setting, and cooling three processes of equipment are placed on the ground in turn. The oven is a horizontal oven, which occupies a large area, has fast heat dissipation, high energy consumption, and the chain plate screws are easy to loosen, reducing the failure rate. High; and the chain plate goes from hot to cold and back to heating, which consumes high energy and causes energy waste; the original equipment has cotton leakage, which is easy to change color and reduces the quality of products; High standard
