Problems solved by technology

This patent overcomes the shortcoming that the dyed object is easily damaged by the high-pressure jet by using a hollow dyeing roller made of porous material, but since there is no relative movement between the dyed object and the dyeing roller, it is easy to cause a dyeing dead zone of the dyed object. Affect the dyeing quality

Abstract

The invention relates to the field of textile dying equipment, in particular to a novel ejector used for supercritical fluid jet dying. According to the jet dying technological process, the novel ejector is installed in a supercritical fluid jet dying device and is connected with a supercritical fluid generation subsystem, a dye dissolution subsystem and a used fluid recovery and separation subsystem. The novel ejector is composed of a squirrel-cage-type washing and dying cylinder, a transmission supporting rotor, two lateral wall plates, a gear disk or a synchronous wheel, a driving gear or a synchronous belt, a backflow pipe, a flow adjusting cover, a sealing cover, cloth guide rollers, an anti-overflow roller, spray nozzles, spray nozzle branch pipes and spray nozzle header pipes. According to the novel ejector, dying is implemented in the mode that dyed materials are always in dynamic contact with rolling washing and dying rollers which form the squirrel-cage-type washing and dying cylinder, and therefore dying dead zones are not prone to being caused; meanwhile, deformation and tension damage of the dyed materials are effectively eliminated though the supporting effect of the rolling washing and dying rollers, wherein deformation and tension damage are generated under the effects of high-pressure jet flows and traction force; the novel ejector is simple and compact in structure and excellent in manufacturability.

Description

1. Technical field [0001] The invention relates to the field of textile dyeing equipment, in particular to a novel injector for supercritical fluid spraying and dyeing. 2. Background technology [0002] Supercritical fluid dyeing technology fundamentally solves the problem of water pollution in the dyeing industry. At the same time, supercritical fluid dyeing technology has the advantages of supercritical fluid recycling, no pollution discharge, no drying of dyed objects, less fiber damage, simple and quick operation, high dyeing efficiency and low energy consumption, and has a good development and application prospect. At present, most supercritical fluid dyeing devices at home and abroad are dip dyeing devices, which must use high-pressure equipment. At the same time, these devices have high requirements for the tightness of the dyeing device, and also require a good quick-opening or reversing structure, which increases the structure of the device. The complexity and inve...
