SU537535A1 - Device for thermal treatment of chemical and natural fiber thread - Google Patents

Description

The invention relates to the heat treatment of yarns from natural and chemical fibers and can be used in light industry.

Various devices for heat treating yarns are known, mainly drying, which contain a heat-insulated chamber with a stirring inside, transported with rollers, one of which — stationary — is heated by-steam. It is also known to perform transsortorizing, its roller with openings for supplying heat carrier on a thread or with two conveyors, with their rollers and coolant supply means into the chamber volume

Closest to the proposed device, there is a heat-insulated chamber, inside which two conveying rollers are mounted in a cantilever, and a manifold for introducing a heat transfer medium.

However, in this device, heat treatment (drying) is performed at relatively low speeds of movement of the thread and insufficient efficiency of heat and mass transfer processes.

The aim of the invention is to increase the productivity and intensify the thread processing process.

The goal is achieved by the fact that the collector communicates with the cavity of the chamber "when

the help of slots made in the end wall of the chamber and located in the planes of movement of the thread, and the inner side walls of the chamber are reinforced with screens,

cavities forming with them for the circulation of the coolant. In addition, one of the rollers is installed with an adjustable angle of inclination not exceeding 6 °, and the second end-face of the camera is made folding.

FIG. 1 shows a device, a longitudinal section; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. one.

The device contains a heat-insulated chamber 1, transporting rollers 2 and 3 with a drive 4 mounted in bearing assemblies 5 and 6. At the end of chamber 1 there are a coolant inlet manifold 7

And the slots 8, and on the inner walls, screens 9 are reinforced, forming with them scaffolds 10, connected to the discharge manifold I. In the cavity 10, the coolant flows through the hole 12. End wall 13

the camera is made folding. The bottom wall of the chamber has slots 14 for threading the thread 15.

When the wall 13 is folded back, thread 15 is threaded and the necessary number of turns is cast onto rollers 2 and 3,

Claims (3)

Claim 1. Device for heat treatment 5 threads of chemical and natural fibers, for example, heating, cooling, drying, containing a thermally insulated chamber, inside of which two are cantilevered. transporting rollers, and a collector for entering the coolant, characterized in that, in order to increase productivity and intensify the processing process, the collector is in communication with the chamber cavity by means of slots made in its end wall and located in the thread movement planes, and on the inner side the walls of the chamber are strengthened by screens that form cavities with them for circulation of the coolant. 20 2. The device according to π. 1, characterized in that one of the rollers is mounted with an adjustable angle of inclination not exceeding 6 °. 3. The device according to π. 1, distinguishing 25 s with the fact that the second end wall of the chamber is hinged. Fig.Z Order 2347/4 Subscription Ed.
