Definitions
- the invention relates to a device for spinning liquid polymer for producing polymer filaments, the liquid polymer flowing through a polymer line with a first heating jacket to a spinning pump with a second heating jacket, which conveys the polymer through several lines to spin packs and through spinnerets squeezes out to form filaments, the lines downstream of the spinning pump, the spinning packs and the spinnerets being located in at least one spinning housing through which heating fluid flows, and a method for heating the spinning device.
- Spinning devices with heating of this type are known from DE 196 24 946 AI and DE 198 09 495 AI.
- the various heated parts of the system are kept at approximately the same temperature level as is specified by the heating fluid used.
- the invention has for its object to ensure that the molten polymer in front of the spinning housing, regardless of the temperature in the spinning housing, can be kept at the lowest possible temperature in order to exclude damage to the polymer as possible.
- this is achieved in the above-mentioned spinning device in that there is a distance of at least 5 mm and preferably at least 10 mm between the spinning housing through which heating fluid flows and on the other hand between the first and second heating mantles and the spinning pump. This distance ensures thermal decoupling and prevents the polymer from being kept at the lowest possible temperature as long as it has not yet entered the heated spinning housing. In this way, damage in the flowing polymer, which could arise from relatively high temperatures, is completely or largely excluded.
- heating fluids which are provided at different temperatures in two storage containers.
- a heating fluid is such.
- B. diphyl which is commercially available in different modifications, with the same heating fluid or different heating fluids can be kept in both storage containers.
- the area between the spinning housing on the one hand and on the other hand the first and second heating jacket is kept free of heating fluid. This maintains the desired temperature differences during operation.
- the supply of heating fluid to the first and second heating mantles can be coupled in many cases; it is possible to pass the heating fluid coming from the reservoir first through the first heating jacket and then through the second heating jacket or in the reverse order to proceed. Most of the time, the first and second heating mantles will be heated with liquid heating fluid. It is also possible to operate the first and second heating mantles with separate heating circuits.
- the polymer used is e.g. B. polyester or polyamide.
- the liquid polymer usually comes from an extruder for melting polymer granules or from a polymerization reactor.
- the polymer enters the spinning pump at temperatures in the range of about 270 to 300 ° C and is forced out through the spinnerets at temperatures of about 295 to 320 ° C.
- Fig. 1 shows the spinning device in a schematic
- the main parts of the spinning device according to FIG. 1 are the spinning housing (1), which is also referred to as a spinning beam, with a plurality of spin packs (2) and spinnerets (3), the spinning pump (4) and the extruder or polymerization reactor (5), of which the liquid polymer through a feed line (6) flows to the pump (4). From there, the polymer is fed into the spin packs (2) through outlet lines (7), only one of which is shown.
- the spinning housing (1) has a heating space (8), which is usually heated with vaporous heating fluid.
- the heating jackets and also the heating room (8) are provided with supply and discharge lines for heating fluid, not shown; this is discussed in more detail in FIGS. 2 and 3.
- a pump (10) can be provided in the feed line (6) if the polymer does not come from an extruder, but from a polymerization reactor (5).
- the spinning pump (4) is located on a support structure (12) that is not heated and also the feed line (6) and the spinning housing
- the shaft (4b) of the pump (4) leads to an electric motor, not shown.
- the feed line (6) is surrounded by a heating jacket (6a), which is referred to here as the "first heating jacket *.
- the spinning pump (4) is located inside a heating jacket (4a), which is referred to here as "second heating jacket” 1 .
- the polymer In the area of the line (6) and the spinning pump (4), the polymer should be kept at the lowest possible temperatures, but still remain flowable.
- the temperature of the polymer in line (7) inevitably rises by about 13 to 15 ° C. due to the pressure increase caused by the pump (4), and the highest temperature lies in the spin packs
- the hot area leading to the spinning housing (1) and belongs to its heating chamber (8) is separated by a distance of at least 5 mm and preferably at least 10 mm from the colder area, given by the two heating jackets (4a) and (6a) and the spinning pump (4).
- the distance which is realized by the support structure (12), brings about a thermal decoupling of the two areas, so that the hotter area does not undesirably heat the colder area.
- the heating of the spinning housing (1), the area of the spinning pump (4) and the line (6) can be carried out largely independently of one another in various ways, since heating fluid is kept at a different temperature in a first storage container (14) and a second storage container (15) will (see Figs. 2 and 3).
- the liquid polymer comes from a polymerization reactor (5) at about 278 ° C.
- the pump (10) e.g. a gear pump
- the filaments run down through a shaft (17) to a winding device.
- Vapor-shaped heating fluid comes from the first storage container (14) and flows through the line (9) into the heating space (8) and then through the line
- the polymer comes from an extruder (5), in which polyester or possibly also polyamide is preferably processed.
- Vapor-shaped heating medium is fed through line (9) into the heating room (8) and from there through line (22) directly into the condenser (20) and from there back.
- Heating fluid which is preferably liquid, comes from the second storage container (15) and first reaches the second heating jacket (4a) in the line (25) and from there through the line (26) to the first heating jacket (6a).
- the return is made through line (24).
- Polyester is spun and diphyl is used as the heating fluid both in the first storage container (14) and in the second storage container (15).
- the distance between the heated spinning housing (1) and the colder area of the two heating jackets with the spinning pump (4) is 20 mm.
- the heating fluid of line (23) has a temperature of 280 ° C.
- the temperature in the area of the nozzles (3) is 310 ° C.
- the heating fluid vapor of the lines (9) and (18) has the same temperature.
- the temperature in the outlet line (7) is 296 ° C.
- the temperature rise in the polymer, caused by the pressure increase by the spinning pump (4), is 14 ° C, and the pump (10) increases the temperature of the polymer by 20 ° C.
- the heating fluid has in the line (9) a temperature of 315 ° C and in the lines (25) and (26) of 298 ° C.
