Изобретение относитс к производству химических волокон, а именно к устройствам дл формовани химических волокон.The invention relates to the production of chemical fibers, namely, devices for forming chemical fibers.

Известно устройство дл мокрого формовани химических волокон в трубку, создающее фильерный комплект, корпус которого имеет проточку на нижней горизонтальной поверхности и коаксиально расположенные в нем резервуар и канал дл подачи полимерного раствора, фильтр и формовочную трубку 1.A device is known for wet forming chemical fibers into a tube, creating a spin pack, the body of which has a groove on the lower horizontal surface and a reservoir and channel for feeding the polymer solution coaxially located in it, a filter and a molding tube 1.

Однако известное устройство не имеет канала дл подачи осадительной жидкости, в ней создаетс застойна зона, нарушаетс однотипность массообмена.However, the known device does not have a channel for supplying a precipitating liquid, a stagnant zone is created in it, the mass exchange is of the same type.

Цель изобретени - интенсификаци производства и улучшение качества волокна путем улучшений условий массообмена полимерного раствора и осадительной жидкости , а также улучшение эксплуатационных свойств.The purpose of the invention is to intensify the production and improve the quality of the fiber by improving the mass transfer conditions of the polymer solution and the precipitating liquid, as well as improving the performance properties.

Поставленна цель достигаетс тем, что в устройстве, содержашем фильерный комплект , корпус которого имеет проточку на нижней горизонтальной поверхности и коаксиально расположенные в нем резервуар и канал дл подачи полимерного раствора.This goal is achieved by the fact that in the device, which contains a die set, the casing of which has a groove on the lower horizontal surface and a reservoir and a channel for feeding the polymer solution coaxially located in it.

фильтр и формовочную трубку, корпус фильерного комплекта имеет сквозное центральное отверстие и на верхней горизонтальной поверхности асимметричную кольцевую проточку дл прохода осадительной жид5 кости.the filter and the molding tube; the die set body has a through central hole and an asymmetrical annular groove on the upper horizontal surface for the passage of a precipitating liquid.

Кроме того, асимметрична кольцева проточка соединена каналами с проточкой выполненной на нижней поверхности корпуса фильерного комплекта, а канал дл подачи полимерного раствора расположен тангенциально к резервуару.In addition, an asymmetric annular groove is connected by channels with a groove made on the lower surface of the die set body, and the channel for feeding the polymer solution is located tangentially to the reservoir.

На фиг. 1 изображено предлагаемое устройство , разрез; на фиг. 2 - то же, вид сверху.FIG. 1 shows the proposed device, the cut; in fig. 2 - the same, top view.

Устройство содержит корпус 1 (фиг. 1),The device includes a housing 1 (Fig. 1),

Claims

2Q, an opening 8 in which the sleeve 5 is mounted, securing the disk 3, is designed to allow the passage of a precipitation liquid. In the housing 1, there is an annular groove 9 for the hydro-laying 7, on which the molding tube is installed (not shown); there are two more annular grooves: at the top of the housing 10 and at the bottom of the housing 11. These grooves 10 and 11 are connected between themselves by channels 12 (openings) for the passage of a precipitating liquid. In the housing 1 there is a tangentially located channel 13 (FIG. 2) with a thread for mounting a nozzle (not shown). Inside the housing 1 (Fig. 1) there is an annular groove, forming a toroidal cavity 14 for the polymer solution, in which the filter bag 2 and the hydraulic laying 15 are placed. The device operates as follows. The polymer solution enters through channel 13 (Fig. 2) into the toroidal cavity 14 (Fig. 1), the solution moves along ring 11 at C Ill. / k / civ-l. f If it.- t, g, j And rises up, passes the filter bag 2 and is forced through the monofillers 4. The precipitating fluid flows through the central hole 8 to the central part of the disk 3, flows around the monofilters 4 and times I Y Uj I vrvciy 1 inV / 111 - XI. "- 1-- destroys the so-called" stagnation zone inside the bundle of forming fibers and thereby destroys the reduced pressure near the center of the disk 3. In addition, the sediment ...... - - - the liquid flows through the groove of T17 canal 12, the bore is washed by the outer monofillers 4. The asymmetrical annular bore 10, the inner edge of which exceeds the exterior directs the flow of the precipitating fluid towards the wall of the tube, which helps to calm the fluid washing the outer monofillers. Claim 1. Device for wet forming chemical fibers into a tube containing a spunbond kit, the body of which has a groove on the lower horizontal surface and a reservoir and a channel for feeding the polymer solution coaxially arranged in it, a filter and a molding tube, to improve operational properties, the casing of the die set has a through center; a real hole and on the upper horizontal surface an asymmetrical annular groove for the passage of precipitation dkkost.

2. A device according to claim 1, characterized in that the asymmetric annular pro1r point is connected by channels with a groove made on the lower surface of the body of the spinneret set.

3. The device according to paragraphs. 1 and 2, characterized in that the channel for supplying polymer growth P is tangentially to the reservoir. Sources of information taken into account during the examination 1. Bleeding set of BF-1 machine 36/54000, drawing No. 1048.0.00.000 SB, 1974.
