DD220625A1 - LARGE SPINNING DEVICE FOR SOLUTION SPINNING - Google Patents

Abstract

The device according to the invention is used for solution spinning, in particular for the production of regenerated fibers. The aim and task is to create a high-performance spinning device with small dimensions and large Filterflaechen that can be varied with little effort according to the operational requirements in the spinning performance. According to the invention, this is achieved by carrying a large spinning device for solution spinning with variable spinning performance consisting of several known single spinning devices, the Spinnduesen, which are equipped with or without Stroemungsparaboloid, the individual spinning devices with a central body in rotationally symmetrical or cylindfoermig lying form with a Filter, seals and Zuführungsstutzen are loesbar connected and optionally by appropriate closure caps 7 and / or inner closure corresponding individual spinning devices are switched off.

Description

Title of the invention

Large spinning device for solution spinning

Field of application of the invention

The invention relates to a device for high-performance spinning of regenerated fibers.

The large-size spinning device according to the invention can be provided with normal or with multiple component nozzles. With the high-performance spinning device all titers of the known Regeneratfasertypen can be spun.

Characteristic of the known technical solutions

It is known to use individual spinning devices and block nozzles with total numbers of holes up to 40,000 Düsenoffnungen for the production of regenerated fibers. Thus, from the patent application D Ol D / 254 431.2 a large spinneret is known in which high numbers of holes are achieved through the use of small nozzles. However, there is the disadvantage here that in all known forms of large spinning devices they are not variably s in their spinning performance, since a shutdown of individual small nozzles is not possible. A capacity utilization of the highly productive Viskosespinnanlagen is therefore not given in the current trend towards titer refinement as a requirement of the textile industry.

'. , '-'. , , "2 -." - .. '' · ^.: Object of the invention

The object of the invention is the development of a spinning device with which one obtains a high spinning capacity, whereby the quality parameters of conventional spinning devices are achieved and exceeded. The spinning device is said to be robust: and easy to maintain, whereby the replacement of individual parts can be carried out without difficulty.

Explanation of the essence of the invention

The invention has for its object to provide a high-performance spinning device with small dimensions and large filter surfaces, which is variable in their spinning performance depending on the operational requirements with little effort. Furthermore, the same spinning pressure should be present at each Einzelspirineinrichtung, even if not worked with the entire spinning capacity.

According to the invention, this is achieved by carrying a large spinning nozzle for solution spinning with variable spinning performance consisting of a plurality of known single spinning devices, the spinnerets, which are equipped with or without paraboloid, with the individual spinning devices with a central body in rotationally symmetrical or cylindrical shape with a filter, corresponding seals and supply nozzle are detachably connected and optionally by means of matched caps and / or inner closure individual devices are switched off.

It is useful - if you combine the caps with a sealing core.

Embodiment 1

The large spinning device shown in FIG. 1 consists of six individual spinning devices 2 with spinnerets 1 which are known per se and carry flow paraboloids. The individual spinning devices 2 are arranged in a ring around a central body 3. Inside the central body 3 is a hat-shaped filter 4, which is pressed over seals 6 to the feed nozzle. For the optional shutdown of one or more spinning devices 2 a matched cap is screwed tightly or placed according to the shape of the spinning device 2 and from the inside is sealed by means of a cylindrical inner closure 8, the feed to the single spinning device

For optional shutdown of one or more ^ V Einzelspinneinrichtungen 2 correspondingly shaped closure caps 7 are screwed with an inner closure 8 in the form of a sealing pin, thereby ensuring that no spinning solution can escape. The central and circular arrangement of the spinning devices 2 makes it possible that the spinning pressure at each point of the large-size spinning device is the same size.

Embodiment 3

The large spinning device shown in FIG. 5 consists of a cylindrical central body 3 in which an analogously designed filter 4 is arranged sealed, being firmly screwed to a supply pipe 5. On the central body 3 in each case four cinzelspinneinrichtungen 2 are arranged with spinnerets 1 or block nozzles 9 in one or two rows. When switching off individual spinning devices 2, their removal and the screwing or placing of closure caps 7 with the corresponding inner closure 8-, as has already been described in the exemplary embodiment 2, are carried out first.
