Definitions

  • the invention relates to a plant for packaging road construction bitumen into large-volume disposable transport units for the cold transport of the bitumen, the disposable packing units are made of flexible plastic having a melting point which is between 20 ° and 50 ° C above the softening point of the bitumen, said Bitumen is cooled to near the softening point of each bitumen processed before bottling
  • Bitumen is very temperature-dependent in its processing since it is liquid at high temperatures and rigid at low temperatures, with a broad transition range between viscous and pasty aggregate states, with the transition from solid to liquid changing the visco-elastic properties of bitumen.
  • bitumen is to be transported over more distances, then the bitumen is so far poured into metal casks and allowed to cool in hot form, which are then either cut on site to get the bitumen out in cold form or heated to remove the bitumen to pour out liquid form. Both ways are unsatisfactory because in any case the disposable containers remain as wastes, which are very difficult to dispose of due to the bitumen contamination.
  • bitumen eg roofing or industrial bitumen
  • plastic films which are then melted down and co-processed with this bitumen.
  • These films are placed in special forms, in which then the hot bitumen filled and is allowed to freeze.
  • this procedure is difficult to apply for large quantities of bitumen, as occurs in the case of road construction bitumen, since many such containers are to be provided in which the bitumen can then be allowed to cool.
  • the commonly used plastic film is not usable.
  • the invention is an object of the invention to provide a system of the type mentioned, with which even for large quantities of bitumen packaging can be selected, which can be melted down with the bitumen, without affecting the quality of the bitumen.
  • this object is achieved in that for cooling the bitumen, a plate heat exchanger is provided in which the temperature difference between the cooling medium and bitumen at the outlet of the heat exchanger between 10 ° and 25 ° C, preferably 15 ° to 20 ° C.
  • a plate heat exchanger is provided in which the temperature difference between the cooling medium and bitumen at the outlet of the heat exchanger between 10 ° and 25 ° C, preferably 15 ° to 20 ° C.
  • the disposable packaging unit is not damaged and on the other hand, the bitumen forms after introduction into the cold packaging material quickly on the wall a stable body. Inside, the bitumen then has time to cool off slowly.
  • the temperature can be kept very targeted, with a good and rapid temperature exchange is possible due to the large heat transfer surface.
  • bitumen In road construction bitumen are usually used with different softening points ring / ball between 45 ° C and up to 60 ° C maximum, which are usually stored at about 140 - 160 ° C in the liquid state.
  • the respective bitumen present is cooled down to a filling temperature which is precisely defined for the actual softening point, at which point the bitumen is already viscous but still pumpable.
  • the interaction between the melting temperature of the plastic material used for the packaging with the processing temperature and the softening point of the bitumen to be processed regulated, just by maintaining this interaction of melting temperature of the plastic with the temperature of the pumped bitumen, the desired effect in terms of "cooling effect" to protect the packaging with the help of the bitumen is achieved.
  • the packaging material is conventionally selected from a plastic which melts at about 115 to 130 ° C and at the filling temperature is still dimensionally stable enough to absorb the bitumen without being damaged.
  • a plastic which melts at about 115 to 130 ° C and at the filling temperature is still dimensionally stable enough to absorb the bitumen without being damaged.
  • this at the conventional processing temperature of bitumen ie about 140 - 160 ° C, completely melts, u.zw. without leaving any fibrous residue. This would make the further processing of the bitumen very difficult.
  • the cooling of the bitumen can be carried out against thermal oil, which has the advantage that the temperature of the oil can be selected specifically matched to the final temperature of the bitumen and at this temperature during processing also can be maintained.
  • the advantage of the process that can be carried out with the system according to the invention is that a precisely defined temperature state is present at the time of filling, since the average temperature in the bituminous compound is precisely maintained at ⁇ 2 ° C.
  • the constancy of the filling temperature for the respective bitumen quality can thus be maintained over the entire, usually over many days uninterrupted filling process, so that on the one hand minimizes the risk of unintentional melting of the packaging plastic and thus the work safety is given by the controlled low temperature, on the other hand the continuity of bottling is not interrupted by subcooling and congealing of the bottoms. It is only with large-scale economic, automated filling of large volumes (eg 50,000 - 100,000 TPA) in large-volume packaging units ( ⁇ 1 m 3 ) possible.
  • the plate heat exchanger can be used to maintain temperature with a heater, e.g. be provided with electric heating elements. This can be prevented that in the case of a short-term shutdown of the plant, the bitumen solidifies within the plate heat exchanger and the plate heat exchanger must be disassembled before further processing.
  • a return flow line can be provided on the filling head, which branches off in front of the filling valve and leads back to the storage container. This makes it possible that the bitumen is permanently moved even when the filling process is interrupted within the circuit, without it being able to solidify.
  • the filling head can be kept at filling temperature via heating elements, in particular electrical heating elements, so that the bitumen present inside the filling head always remains liquid and does not solidify even after the filling operation has come to a standstill.
  • bitumen is held by a heater 2 to the storage temperature of about 140 - 160 ° C.
  • Bitumen is pumped into the bitumen line 5 by the feed pump or, if no bitumen can be removed, via the return flow line 4 in the Container returned.
  • the line 5 opens into a heat exchanger 6, from which the cooled bitumen passes via the filling line 7 to the filling head 8. Through this filling head 8, the bitumen is introduced into the transport container 9.
  • the heat exchanger is acted upon via a coolant circuit line 10 by a pump 11 with coolant, in the present case thermal oil, whose temperature is maintained at the desired value via the cooler 12, the temperature difference between the cooling medium and bitumen at the outlet of the heat exchanger between 10 and 25 ° C, preferably between 15 and 20 ° C.
  • coolant in the present case thermal oil, whose temperature is maintained at the desired value via the cooler 12, the temperature difference between the cooling medium and bitumen at the outlet of the heat exchanger between 10 and 25 ° C, preferably between 15 and 20 ° C.
  • At 13 is a transport container in the empty state before filling and 14 an already filled container after filling shown.
  • the entire system is monitored for temperature using conventional thermocouples and controlled by a central computer.
  • the thermocouples and the control computer are not shown in the present case.
  • the filling is electronically controlled via filling valves on a filling scale.
  • a special suspension device for receiving the handle of the disposable transport units is provided on pallets, in particular steel pallets.
  • the disposable transport units are held by the support means until the bitumen is stable enough that it needs no further support.
  • the filled containers 14 are then under roof, but well ventilated, turned off to cool inside to the ambient temperature. Since bitumen has a strong insulating effect, the cooling time is depending on the ambient temperature between 4 - 7 days, u.zw. for containers of about one cubic meter in content.
  • the containers filled in this way can then be transported normally by rail, ship or truck without any temperature-retaining device, in order then to be melted in place together with the disposable packaging and further processed.
