Definitions
- the invention relates to a device for spinning according to the preamble of Claim 1.
- Such devices are used for melt spinning synthetic threads and are known for example from DE 195 40 907 A1.
- a spinning beam from a melt source such as polymer melt supplied to an extruder or a polymerization system.
- the melt is usually one within the spinning beam or by means of a distributor fed several dosing pumps, which the melt with a defined Volume flow is distributed to spinning pots in which the filaments are formed.
- the elements of the spinning beam i.e. distributors, metering pumps, piping and Spin pots are heated together and are surrounded by insulation.
- spinning is from Polyamide 6.6 feared by man-made fiber manufacturers. If there is a formation of post-condensed polymer and thus lead to a blockage of the lines the spinning beam should be completely dismantled and the clogged ones Elements must be regenerated in an external furnace, i.e. at temperatures of Can be pyrolytically cleaned at 450 to 550 ° Celsius. This situation can affect everyone Plant downtimes or when polymer throughputs are too low. But it may be necessary even if an unexpected operating state does not occur be to regenerate the spinning beam at certain intervals.
- the spinning beam over a permanently installed one or one that can be temporarily attached to the spinning beam Regeneration heating has the spinning beam to the required if necessary Pyrolysis temperature warmed.
- the advantage of the invention is that the regeneration process can thus be carried out without extensive disassembly of the spinning beam can.
- the spinning beam can be built as a whole unit, so that it can be dismantled Flanges and other leakage risks are not required, which means the spinning beam is cheaper and simpler.
- the pyrolysis temperature required for the regeneration process can in the case a spinning beam heated by heat transfer medium normally not can be achieved with this heating principle. For this reason, it is for the regeneration process a separate regeneration heater is provided. It is in shape an electric resistance heater or a hot air blower or the like executed.
- the regeneration heater is in to carry out the regeneration process able to bring the melt-carrying components to temperatures above the Heating up the operating temperature.
- This temperature is preferably in the range from 450 to 550 ° C, in which the organic deposits thermally decompose become.
- the thermal decomposition of the organic deposits results in Spinning beam gases and vapors.
- the Invention provided a means for suction of the resulting gases and vapors.
- the extracted gases and fumes filtered.
- the spinning beam is heated with a heat transfer medium
- means are provided to the during the regeneration process by evaporation of the heat transfer medium evacuating vapors.
- a device for spinning according to the invention is shown in section. From an extruder 1 via a melt feed line 2, the spinning beam 3 polymer melt fed. Instead of extruder 1, one can also be used here direct polycondensation serve as a source for the polymer melt.
- the melt feed line 2 is divided into two spinning pumps 4 on.
- the spinning pumps 4 distribute the polymer melt in a metered manner via the distributor lines 5 on the individual, housed in the spin pot holders 6 and Spin pots, not shown here. In these spinning pots, the polymer melt becomes the filaments are extruded to form the thread. Both the number the spin pot receptacles 6 and the number of spin pumps 4 are exemplary here selected.
- a cavity 7 is formed, which with a Heat transfer medium is filled.
- This heat transfer medium circulates over one Inlet 8.1 and an outlet 8.2 through an operating heating medium 8.3.
- the operating heating means 8.3 to operating temperature heated, the usual operating temperature being 250 to 330 ° C.
- Oil or diphyl are known as the heat transfer medium.
- Diphyl has the advantage that it is in the liquid and gaseous phase in the spinning beam 3, so that cold components of the spinning beam 3 by condensation of the gaseous Diphyls are specifically heated by the resulting heat of condensation.
- the operating heating of the melt feed line is 2, which interacts with the service heating 8.3 or is operated separately, here not shown.
- the length of the split melt feed line 2 as well as the length of the Distribution lines 5 to the respective spin pot receptacles 6 for each branch is the same and thus the residence time of the melt in the melt-carrying Parts of the spinning beam 3 is the same for each spinning pot holder 6, it can despite the uniform temperature in the spinning beam 3 to degenerate the polymer come.
- a regeneration heater is therefore provided on the spinning beam 3 in FIG. 1, with which the spinning beam 3 to a regeneration temperature above the Operating temperature can be heated.
- the regeneration heater is a hot air blower that comes from the Hot air outlet 10, the filter 12, the blower 13, the regeneration heating medium 14 and the hot air supply 9 there.
- a control means 15 detects the temperature by means of a temperature sensor 19 in the spinning beam 3 and controls the fan 13 and the regeneration heating means 14 based on a setpoint / actual value comparison.
- the spinning pots not shown here removed from the spin pot receptacles 6, so that the openings of the distribution lines 5 are open.
- An opening 2.1 is provided on the melt feed line 2, through which compressed air can be blown into the melt line system.
- the melt feed line 2 is via the opening 2.1 with a suction device 2.2 connected by which arise during the regeneration process Gases are sucked off and filtered.
- the regeneration heater can be permanently connected to the spinning beam. It is but also possible and economically sensible, the filter 12, the blower 13, the Regeneration heating means 14 and the control means 15 can be dismantled, see above that there is a need for the hot air supply 9 and the hot air outlet 10 of the regenerating spinning beam can be attached. This makes it enough for a manufacturer of man-made fibers, only one regeneration heater for several spinning beams reproach.
- the spinning beam according to the invention also comprises other embodiments the operational heating, such as the (electrical) trace heating of the melt-carrying components. These are known from the prior art. The same applies to the following figure.
- FIG. 2 shows a variant of the spinning beam 3 shown in FIG. 1.
- the Regeneration heating means 16 are based here on additional electrical heating of the spinning beam 3. Although here the cavity of the spin beam is not is flowed through by hot air, is still a collection reservoir 8.4 for the Heat transfer medium provided, as a rule, the heat transfer media used are not heat-resistant in the range of the regeneration temperatures. in the Spin beam 3 remaining residues of the heat transfer medium evaporate during of the regeneration process and are sucked off by a suction device 20.
- the spinning beam is well insulated from the outside while the components conduct the heat relatively well inside. Thereby and through the heat radiation inside the spinning beam 3 there is a sufficiently uniform heat distribution reached, the requirements for the regeneration process Temperature uniformity are not as high as in spinning.
- the number and the respective location of the regeneration heating means 16 are derived from the Construction of the spinning beam 3 and can by a specialist accordingly be interpreted.
- the regeneration heating means 16 are as heating coils, Heaters etc. run and transfer the heat through heat conduction or Thermal radiation.
- the regeneration heating means 16 can either be permanently installed in the spinning beam 3 or be designed to be replaceable. Especially in connection with heating elements, it is advisable to use them especially for this provided openings in the normal operation, which are closed by plugs Use spinning beam 3.
- the spinning beam 3 is heated here in normal spinning mode (service heating) not via a heat transfer medium, but through heating means 17 on the individual melt-carrying parts, which are executed here as trace heating are.
- heating means 17 are controlled by a control means 18 which e.g. the Temperature control includes.
- the control means 18 has a separate one Operating mode in which the heating medium with a higher regeneration temperature are operable, so that the regeneration process with the operating heating medium at the same time is feasible.
