Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a yarn fluid treatment facility in a synthetic fiber manufacturing facility.

(Prior Art) A fluid nozzle for a yarn ejects a compressed fluid from a fluid injection hole that opens in a yarn guide hole through which the yarn travels to give a loop or crimp to the yarn, or to apply a spinning oil agent to the yarn. It is applied evenly and is widely used as an interlace nozzle or an air nozzle in the production of synthetic fibers.

When a yarn is processed by using such a nozzle, there is a problem of environmental pollution such as scattering of oil agent adhering to the yarn to be processed and noise generation due to fluid injection. As a countermeasure, a cover is provided on the fluid nozzle. Is proposed.

Conventionally, such covers include those in which the fluid nozzle is simply surrounded by the cover, and those in which an exhaust device with an opening at one end of the cover is attached to discharge spattered spinning fluid etc. out of the system and further reduce noise. It's being used.

FIG. 2 shows an example of such a conventional device, in which the traveling yarn Y is introduced into a cover 2 surrounding the fluid nozzle 1, where it is fluid-treated and then led out from the cover 2. The compressive fluid ejected from 1 is exhausted to the outside of the system by the exhaust device 5 via the exhaust pipe 4.

However, as shown in FIG. 2, in the fluid treatment device in which the exhaust device 5 is attached to the cover 2, spattered spinning oil and the like are discharged to the outside of the system, but foreign matter such as scum adheres to the exhaust pipe 4 over time. Then, it accumulates and finally leads to blockage.

When the exhaust pipe 4 reaches a closed state, the compressive fluid ejected from the fluid nozzle 1 is discharged from the gap of the cover 2 with spraying of a spinning oil agent or scum on the sound absorbing material 3 attached to the inner surface of the cover 2. It adheres to and accumulates on the environment, reducing the sound absorption effect and polluting the environment.

For this reason, the exhaust device must be disassembled and cleaned regularly, the work is troublesome, a large number of workers are required, and the production of the yarn must be temporarily stopped.

(Purpose of the Invention) The present invention has been made to solve such a conventional problem, and the scum of the spinning oil agent or the like adhering to the inside of the exhaust pipe is continuously or intermittently removed to remove the exhaust pipe. The purpose of the present invention is to prevent the clogging of the spinneret and prevent the spraying and scattering of the spinning oil agent and the like and the reduction of the sound absorbing effect of the sound absorbing material mounted on the inner surface of the cover. Such an object is achieved by the following constitution.

(Structure of the Invention) That is, the present invention comprises a fluid nozzle for injecting a compressive fluid to process a yarn, a cover surrounding the nozzle, and an exhaust pipe connected to an exhaust device opened at one end of the cover. A fluid treatment device for yarns, characterized in that a steam blow-out nozzle having a jet outlet in the exhaust direction is arranged in the vicinity of the joint between the cover and the exhaust pipe.

Hereinafter, the present invention will be described in detail with reference to examples.

(Embodiment) FIG. 1 is a schematic process drawing including a partial cross section showing an embodiment of the present invention.

In the figure, 11 is a fluid nozzle that fluid-treats the running yarn, 12 is a cover that surrounds the fluid nozzle 11, and a sound absorbing material 13 is attached to the inner surface thereof. An exhaust pipe 14 is provided in the cover 12 in the horizontal direction and is connected to a waste liquid tank 15.

An exhaust pipe 16 is provided above the waste liquid tank 15, and the exhaust pipe 16 is connected to an exhaust device 17 such as a fan or a blower. 18 is a waste liquid pipe.

Reference numeral 19 denotes a steam blowing nozzle provided near the joint portion 22 of the exhaust pipe 14, the tip of which is attached parallel to the central portion of the exhaust pipe 14 and the ejection port 20 directed toward the exhaust direction. The end is connected to the steam pipe 21.

The position of the tip of the nozzle is preferably about 50 mm before and after the connecting portion, but is not limited to this.

In such a device, the traveling yarn Y is processed in the cover 12 by the fluid nozzle 11 as described above, but since the exhaust device 17 constantly sucks and exhausts the inside of the cover 12, scum does not adhere or accumulate. Less fluid nozzle 11
A fluid containing a spinning oil agent such as compressed air or steam ejected in step 1 is discharged from the exhaust pipe 14 through the waste liquid tank 15 to the outside of the system by the exhaust device 17. In this case, when the exhaust fluid is introduced into the exhaust pipe 14, scum and the like are gradually deposited there with the passage of time, but the nozzle 19 is adapted to spout steam at regular intervals or continuously. Therefore, scum etc. can be removed quickly and easily.
It does not adhere or deposit on the inner wall of the, and the above-mentioned trouble does not occur.

The steam and the exhaust fluid ejected from the blow-out nozzle 19 are guided to the waste liquid tank 15, where the liquid component is collected in the waste liquid tank and the gaseous substance is discharged from the exhaust device 17 to the outside of the system through the exhaust pipe.

In addition, the blowing angle of the steam blowing nozzle 19 is the exhaust pipe 1
It is preferable to make them parallel to No. 4, but there is no particular limitation as they may have a certain angle. Further, although the exhaust pipe 14 is illustrated horizontally in FIG. 1, this angle is not particularly limited. The temperature of the steam blown out from the blow-out nozzle 19 is usually 100 ° C. or higher, preferably 120 to 180 ° C. for saturated steam, and the removal efficiency decreases when the temperature is 100 ° C. or lower, and at 180 ° C. or higher, the facility cost or management is low. Not very good. It goes without saying that steam may be superheated steam. When the steam is blown out intermittently as described above, it may be manually operated, but it is also possible to use a timer or the like to operate the on-off valve at regular intervals to blow out steam. Alternatively, the scum accumulation may be automatically removed by a means for detecting the accumulation state, for example, a pressure difference between the cover 12 and the outlet of the exhaust pipe 14 or the outside, and detection by a level meter of the accumulation part.

Next, a more specific description will be given of an example in which the device of the present invention shown in FIG. 1 (spouting steam for 1 minute at intervals of 2 hours) and the conventional device shown in FIG. 2 are used under substantially the same conditions. Nylon multifilament with OPU of 1% and 2000de was subjected to yarn entanglement treatment at a running state of 1500m / min.

Table 1 shows the results of scum adhesion in the exhaust pipe (diameter 28 mm) at a compressed air pressure of the fluid nozzle of 5 kg / cm ² G and a flow rate of 1 Nm ³ / min.

As is clear from Table 1, the conventional apparatus had no particular problem on the 1st to the 3rd days, but the scum accumulation increased from the 5th day and almost clogged on the 7th day, and the blowout from the cover increased. At the same time, the noise increased and it became difficult to use any more. On the other hand, in the device of the present invention, no change was observed after the 7th day, scum was not accumulated even after the elapse of 30, and leakage of spinning oil and the like from the cover and noise up. Almost never happened.

(Effects of the Invention) As described above, according to the present invention, the troublesome work of temporarily discontinuing the production and disassembling and cleaning the exhaust pipe and the like is eliminated, and the production of the yarn is efficiently and stably performed. It was possible.
