Definitions
- the invention relates to a device for generating Polymer filaments by spinning molten Polymers, consisting of a via a heatable Polymer line with the surrounded by a heating jacket Spinning pump connected to the polymer melt Extruder or polymerization reactor and several of the Spinning pump outgoing polymer lines, each with one of a heating fluid permeable spinning housing arranged with the spinnerets spin packs are connected, as well as a method for heating the Contraption.
- the invention has for its object to ensure that in the method described above the molten polymer in front of the spinning housing, independent from the temperature in the spinning housing, as low as possible Temperature can be maintained to damage the To exclude polymers as possible, and the polymer melt heated in a simplified manner from spinning temperature becomes.
- this is achieved in that the between the extruder or polymerization reactor and the Spinning pump attached polymer line from a Schumantelrohr consists, spinning pump and spin housing over an unheated one leading to the spinning housing Connected polymer lines receiving support structure are.
- the unheated support structure ensures a thermal decoupling and prevents the polymer, as long as it is not in the heated spinning case occurred at the lowest possible temperature is held and thus damage to the molten Polymers caused by relatively high temperatures, completely or are largely excluded.
- the heating of the molten polymer at spin-off temperature exclusively by those prevailing in the spinning housing Temperature. In this way, damage to the molten polymer wholly or largely locked out.
- the successful operation of the spinning device is achieved that with from a first Reservoir discharged vaporous a temperature from 280 to 330 ° C having heating fluid, the spinning housing, then with the emerging from the spinning housing vaporous heating fluid surrounding the spinning pump Heating jacket and with a from a second storage container discharged a temperature of 270 to 300 ° C having Schufluid of the polymer line between extruder or Heating jacket surrounding heating jacket are heated, wherein the temperature of the spinning housing supplied vapor heating fluid by 10 to 40 ° C higher than that Temperature of the heating jacket of spinning pump and Polymer line supplied heating fluid is.
- the spinning housing and with out of the second reservoir indicated a temperature of 270 up to 300 ° C having heating fluid of the polymer line surrounding between extruder or polymerization reactor Heating jacket and then with the from the heating jacket emerging heating fluid surrounding the spinning pump Heating jacket to be heated, the temperature of the Spinngephase supplied heating fluid by 10 to 40 ° C higher as the temperature of the heating mantle of spinning pump and Polymer line supplied heating fluid is.
- heating fluid is suitable e.g. Diphyl, that in different Modifications is commercially available, where in both Reservoirs the same heating fluid or else can hold different heating fluids.
- the first and second heating jacket kept free of heating fluid. Thereby be the desired temperature differences during the Maintain operation.
- the supply of heating fluid to the first and second heating mantle can be coupled in many cases; that's it possible, the heating fluid coming from the reservoir first through the first heating jacket and then through the second Heating jacket to lead or in reverse order to proceed. Usually you will get the first and second Heat the heating jacket with liquid heating fluid. It is further possible, the first and second heating mantle also with operate separate heating circuits.
- polymer used z. As polyester or polyamide.
- the liquid polymer usually comes from an extruder for melting polymer granules or from a Polymerization reactor. The polymer occurs at temperatures about in the range of 270 to 300 ° C in the spin pump, and it goes through with temperatures of about 295 to 320 ° C the spinnerets pressed out.
- the main parts of the spinning apparatus of FIG. 1 are the Spinning housing (1), which is also referred to as a spinning beam, with several spin packs (2) and spinnerets (3), the Spinning pump (4) and the extruder or polymerization reactor (5), from which the liquid polymer passes through a feed line (6) flows to the pump (4). From there, the polymer gets through Outlet lines (7), of which only one is shown, led into the spin packs (2).
- the spinning housing (1) has a heating space (8), usually with vaporous heating fluid is heated.
- the heating jackets and also the heating space (8) are not shown Supply and discharge lines for heating fluid; in Fig. 2 and 3 will be discussed in more detail.
- the supply line (6) may be provided a pump (10), if the polymer is not from an extruder but from a polymerization reactor (5) comes.
- the spinning pump (4) is on a support structure (12) that is not is heated and also the supply line (6) and the spinning housing (1) connects.
- the shaft (4b) of the pump (4) leads to a not shown electric motor.
- the supply line (6) is from a heating jacket (6a) surrounded, here as “first Heating jacket. "The spinning pump (4) is located inside a heating mantle (4a), here as “second heating jacket” is called.
- the hot area leading to the spinning housing (1) and heard of his heating chamber (8) is by a distance of at least 5 mm and preferably at least 10 mm from colder area, given by the two heating jackets (4a) and (6a) and the spin pump (4), spatially separated. Of the Distance realized by the support structure (12) is, causes a thermal decoupling of the two Areas so that the hotter area is the colder area not heated in an undesirable manner.
- the heating of the spinning housing (1), the area of The spinning pump (4) and the line (6) can be different Way largely independent of each other, since Heating fluid in a first reservoir (14) and a second reservoir (15) with different Temperatures is maintained (see Figs. 2 and 3).
- compare Fig. 2 which is especially suitable for polyester, comes the liquid polymer from a polymerization reactor (5) at about 278 ° C.
- the pump (10) eg a gear pump
- the melt in Shape of numerous filaments (16) is pressed down.
- not shown manner See also Fig. 1) run the filaments through a Shaft (17) down to a winding device.
- the polymer comes from an extruder (5), in which preferably polyester or possibly also Polyamide is processed.
- Steam-shaped heating medium is through the line (9) in the heating space (8) and from there through the line (22) directly into the capacitor (20) and returned from there.
- heating fluid which is preferably liquid, and passes in the line (25) first in the second Heating jacket (4a) and from there through the line (26) in the first heating jacket (6a). The return takes place through the Line (24).
- Pol yester is spun and Diphyl is used as heating fluid both in the first reservoir (14) and in the second Reservoir (15).
- the distance between the heated Spinning housing (1) and the colder area of the two Heating jackets with spinning pump (4) is 20 mm.
- the heating fluid of the line (23) has a temperature of 280 ° C.
- the temperature in the range of Nozzle (3) is 310 ° C, and the same temperature has the Schufluiddampf the lines (9) and (18).
- the temperature is 296 ° C.
- the pump (10) raises the temperature of the polymer by 20 ° C.
