Loose fiber dehydration process

Abstract

The application provides a loose fiber dehydration process, and belongs to the technical field of liquid-phase continuous treatment of textile materials. To-be-treated loose fibers are conveyed by a guide belt, extrusion water drainage is completed when the loose fibers pass through the space between rollers arranged in pairs, drain holes are formed in the guide belt, extruded water is drained through the drain holes, each pair of rollers comprises an upper roller and a lower roller, the rollers are driven by an oil cylinder, and at least one of the upper roller and the lower roller is provided with a buffer device. The corresponding rollers are driven to deform when the surface pressure of the loose fibers reaches a certain range, and the corresponding upper roller and / or lower roller are / is pulled to move until the distance between the upper roller and the lower roller is proper. The loose fiber dehydration process disclosed by the application is applied to loose fiber dehydration and has the advantages of being high in dehydration efficiency, timely in drainage, good in loose fiber spinnability and the like.

Description

Technical field[0001]The application relates to a loose fiber dehydration process, which belongs to the technical field of liquid continuous processing of textile materials.Background technique[0002]In the process of dyeing and rinsing loose fibers, dehydration (including removal of dye solution and removal of water) is inevitably involved.[0003]There are two common ways of dehydration:[0004]Method one, dehydration by centrifugal method. Centrifugal dewatering is intermittent dewatering. Usually, loose fibers are piled in a dewatering cylinder, a certain speed is applied to the dewatering cylinder, and a drainage hole is set on the dewatering cylinder. The dewatering cylinder rotates to give centrifugal force to the loose fibers inside. Under the action of the centrifugal force, the moisture in the loose fiber is released from the surface of the loose fiber and is discharged through the drainage hole, thus achieving the purpose of moisture separation.[0005]The second way is to dehyd...

AI Technical Summary

Problems solved by technology

In the process of breaking up, based on the mechanical action of the beaters, the physical properties of the loose fibers will be reduced, and the spinning performance and mechanical properties of the fibers will be reduced or weakened; and the above-mentioned treatment process still has energy consumption. Large, poor drainage and other defects, such as the need to provide sufficient centrifugal and extrusion power, but for the conveyor belt method, the water cannot be discharged in time, and when it accumulates too much, the pressure will even rebound on the conveyor belt and rollers, resulting in conveyor belt breakage, damaged roll
