Loose fiber centrifugal dehydration dyeing device

Abstract

The invention relates to a loose fiber centrifugal dehydration dyeing device which comprises a main cylinder. A loose fiber cage is arranged in the main cylinder and comprises a central sleeve and anouter barrel, the central sleeve is arranged in the outer barrel, a plurality of small holes are formed in the central sleeve and the outer barrel, a central screw is arranged in the central sleeve, amotor is arranged outside the main cylinder, the central screw is fastened and connected with the loose fiber cage, a power output end of the motor is in transmission connection with the central screw and can drive the central screw to carry the loose fiber cage to rotate in the main cylinder, at least three suspension systems which are connected with the main cylinder are arranged on the peripheral side of the main cylinder, a water outlet end of a circulation washing and dyeing system is communicated with the central sleeve, and a water inlet end of the circulation washing and dyeing systemis communicated and connected with a drain opening of the main cylinder. The loose fiber centrifugal dehydration dyeing device has the advantages that loose fibers loaded in the loose fiber cage canbe centrifugally dehydrated by the loose fiber centrifugal dehydration dyeing device, accordingly, residual dye and chemicals in the loose fibers can be reduced to a great extent, the washing frequencies can be reduced, and water, power and the time can be saved; energy can be saved in operation procedures of the loose fiber centrifugal dehydration dyeing device, environments can be protected in the operation procedures of the loose fiber centrifugal dehydration dyeing device, and the dyeing quality can be greatly improved.

Description

technical field [0001] The invention relates to a dyeing machine, in particular to a centrifugal dehydration dyeing device for loose fibers. Background technique [0002] At present, in the printing and dyeing industry, the bulk fiber dyeing devices used to dye various natural or artificial bulk fibers such as cotton, acrylic, wool and cashmere are traditional bulk fiber dyeing devices. This traditional loose fiber dyeing device includes a main cylinder, in which a loose fiber cage is arranged, and a central nozzle is installed in the loose fiber cage, and the lower end of the central nozzle is fixedly connected with the cage bottom of the fiber cage. A heat exchange coil is installed under the cage bottom of the loose fiber cage, and one end of the heat exchange coil protrudes outside the main cylinder and communicates with the steam source. A motor and a water pump are arranged at the bottom of the main cylinder, and a chemical material cylinder is arranged on one side of...

AI Technical Summary

Problems solved by technology

A large amount of Na should be added when dyeing with reactive dyes 2 SO 4 To promote dyeing, in this process, some are directly added to the main vat, and some are added to the main vat through the material barrel. Both methods have defects. The first one is directly added to the main vat, which will cause Na 2 SO 4 Insufficient dissolution causes staining and Na 2 SO 4 Waste, the second possibility of clogging the feeding pipeline

The hard connection between the loose fiber cage and the base of the loose fiber cage is prone to dye liquor leakage, which reduces the effective flow of dye liquor, resulting in increased power consumption and decreased dyeing quality.
