Definitions

  • the invention relates to an extrusion line for the production of plastic profiles, preferably plastic pipes, comprising at least one extruder, a tool, a calibration and further downstream devices. Furthermore, the invention relates to a method for increasing the cooling capacity of an extrusion line for extruding a plastic profile, in particular a plastic tube comprising the steps of: a) melting plastic in an extruder, b) molding a plastic strand and feeding the plastic strand to a tool, c) Forming a plastic profile by means of the tool, d) calibrating and curing by cooling the profile in a calibration, wherein in addition to the external cooling in the calibration, the profile is cooled in the interior.
  • the invention relates to a method for energy-efficient extrusion of a plastic profile, in particular a plastic tube, comprising the steps of a) melting plastic in an extruder, b) molding a plastic strand and supplying the plastic strand to a tool, c) forming a plastic profile by means of Tooling and d) Calibration and curing by cooling the profile in a calibration, which in addition to the external cooling in the calibration, the profile is cooled inside.
  • the present invention therefore provides the possibility of offering an extrusion line with the aim of removing the heat arising during internal and / or external cooling from the process and making it as useful as possible. Furthermore, the invention encompasses the invention of offering a corresponding method.
  • the solution of the object with regard to the extrusion line is characterized in that at least the tool has at least one opening and, viewed in the extrusion direction, an extraction is arranged in front of the tool, by means of the air in the interior of the Kunststoffpro fils interchangeable is.
  • the extracted warm air is supplied to a consumer for energy recovery.
  • This countercurrent principle has the advantage that, compared to the tube temperature at the end of the extrusion section, colder air is sucked through the interior of the tube counter to the direction of extrusion. This air warms up on the way through the pipe to the pipe inner wall, wherein the tube temperature also increases counter to the extrusion direction. Thus, there is always a temperature difference between the air and pipe inner wall, resulting in a permanent heat flow from the pipe into the air. The heat thus removed from the process is returned to the process and contributes to energy optimization. The heat is thus used meaningfully and does not evaporate in the atmosphere.
  • the solution proposed in connection with the preamble of claim 2 is that after the calibration around the extruded tube, a chamber is arranged, wherein a fan is arranged on the chamber, by means of the air against the extrusion direction at the Outside wall of the extruded tube can be passed over.
  • the chamber is sealed at least on one side.
  • a preheating station for the raw material to be fed to the extruder.
  • a raw material is primarily plastic granules used, but it can also be used for preheating other materials such as PVC powder.
  • This has the advantage that the raw material already has a higher temperature than the room temperature and thus less energy in the form of heating energy in the extruder. which must be applied. This is especially true for the introduced mechanical energy.
  • the heating energy that is introduced via the cylinder wall is not so relevant for melting, since above all the mechanical energy (drive energy) is converted into frictional heat.
  • the temperature must not be in an area where the plastic granules used already glued.
  • This can be controlled, for example, in that the exhaust device can be controlled and / or regulated in the volume flow, but also in that the energy not required for heating the material is supplied to a heat exchanger and / or for driving further units, for example a Stirling engine, and / or or for the production of process refrigeration is used.
  • the dissipated heat can only be used exclusively for driving the aggregates.
  • the solution of the object with regard to the method is characterized in conjunction with the preamble of claim 8 in that, for the internal cooling of the profile, the air is sucked in counter to the extrusion direction by means of a suction device.
  • the air is supplied to a consumer for the use of heat.
  • a consumer the preheating of granules or the operation of ben of aggregates as well as the supply to a heat exchanger or for generating process refrigeration provided.
  • At least one flow velocity is achieved, which is located in the turbulent range.
  • the best possible turbulence of the air in the interior and / or on the outer wall of the profile is achieved, resulting in a high exchange of air on the inner and / or outer wall of the Pro files and thus draws a good cooling performance.
  • the methods are particularly useful when extruding a thick-walled plastic tube, since relatively long residence times of the extrudate in the line are required here, and thus the volume of air can be exchanged several times, which results in a particularly high level of effectiveness. It is therefore proposed that heat occurring in or on the extruded tube be returned to the extrusion process by passing air along the surface of the extruded tube in the opposite direction to the extrusion direction and with the amount of heat gained for preheating the plastic granulate required for the extrusion process or Drive is used by aggregates such as a Stirling engine or for generating process refrigeration.
  • the proposed extrusion lines and the proposed methods are particularly suitable for thick-walled plastic pipes and pipes with large to very large diameters whose residence time within the extrusion line is in the hour range, so it is relatively large.
  • the cooling capacity is increased in an extrusion line, with which considerable advantages are associated.
  • the overall cooling length is shortened if one leaves an existing output power unchanged, or one can increase the output power, as long as the entire cooling length is maintained.
  • this energy-efficient extrusion of a plastic profile is achieved because the energy extracted from the profile is at least partially recycled to the process.
  • the extracted air does not affect the melting behavior in the extruder because it does not come into contact with the extruder.
  • the air is sucked through the extruder and measures taken that there is no interference. Due to the proposed turbulent flow, a particularly effective cooling is achieved.
  • cooling is known with full water tanks or water spray tanks.
  • the external air cooling can be an effective retrofit, even if the pipe interior cooling is not possible because of lack of breakthrough in the pipe head.
  • the aim is to keep the highest possible percentage of the heat generated in the system, not only by preheating, but also e.g. via conversion into mechanical drive energy.

  • Extrusion line a pipe 9 is manufactured.
  • the suction 6 is arranged at the beginning of the extrusion line directly on the tool.
  • the corresponding suction direction is indicated schematically by the arrow.
  • the tool 2 has an opening 8, the opening 8 communicates with the suction 6 in connection, so that the suction 6, the air volume in the interior of the tube 9 can suck through to the end of the extrusion line in the region of the separator 5.
