Description

The invention relates to the manufacture of chemical threads, namely, devices for separating the working (aggressive) medium from the moving thread during molding and finishing.

The purpose of the invention is to improve the performance properties.

The drawing shows a diagram of the device.

The liquid separation device consists of a housing 1 with nozzles for inlet 2 and outlet 3, sectional chambers 4, a locking valve 5, a thread-holding tube 6 in the form of a spring, a drainage tube 7, a fitting 8 for supplying compressed air and a valve 9 for draining separated fluid.

In the housing 1 at the end of the thread-conducting tube 6 there is arranged a means for direct air supply at an obtuse angle to the direction of movement of the thread, consisting of a fixed sleeve 10 with a cavity 11, which includes a tapered nozzle 12 rigidly mounted with a nozzle 3 outlet

threads. The compressed air supply fitting 8 has a non-return valve 13 and is connected to the cavity 11 of the fixed sleeve, which has a conical shape. The nozzle 12 has the possibility of axial movement in the conical cavity 11 of the sleeve 10.

The device works as follows.

The valves 9 and 13, which are installed after the forming tube or the tube with the finishing liquid, are initially closed at the time of refilling. The finishing liquid fills the chambers in the absence of the thread and, flowing out of the nozzle 3, creates a velocity head in the thread-conducting tube 6. The thread carried by the liquid passes through the thread-conducting tube and is directed to subsequent operations (washing, drying and transportation).

In the operating mode, valves 9 and 13 open, the main fluid is separated from the thread and removed from the device through valve 9. Some part of the liquid remains in the thread

the form of a fur coat. Compressed air enters the cavity 11 of the sleeve 10, the passage through the gap between the conical surfaces of the cavity of the sleeve and the nozzle 12. The air acquires a directional motion at an obtuse angle to the direction of movement of the thread. A thin film of the air cone acts on the thread and blows off the remaining fur coat from it. The air flow rate is 1-3 m3 / h, depending on the thickness of the thread. The air moves along the threading channel, passes through the coils of the spring into the upper chamber and together with the droplets of liquid is drained through the drain tube 7. At the same time air leaks from the fitting of the thread outlet, therefore, no skipping of the fur coat and drops of aggressive working medium for subsequent operations does not occur. . The optimum size of the annular slit from which air flows into the thread-conducting tube is 0.5-1 mm. This creates a high-speed air curtain, with low air flow, reliably separating work

whose fluid is from a continuously moving filament. In order to guarantee air outlet with droplets of liquid from the device, the cross-sectional area of the drain pipe exceeds the cross-sectional area of the filament exit pipe /

The use of the invention contributes to the improvement of the operational properties of the device by increasing the efficiency of the separation of liquid from the filament.
