Definitions

  • the present invention relates to a device for receiving fluids mixed with solids, in particular for receiving wastewater from nuclear power plants, with a body open on one side, which defines an interior.
  • the invention further relates to a device for removing liquid from a receiving device having an interior space, a tube, which communicates with the interior for discharging the liquid in a conductive connection, and a lid for resting on the receiving device, wherein the lid in the region of the interior of a Opening has.
  • Wastewater from a nuclear facility can be evaporated for disposal.
  • a method and a device suitable for this purpose are, for example, from DE 31 14 060 A1. known.
  • the object of the present invention is therefore to provide a device for receiving liquids mixed with solids and a device for removing liquid from a receiving device, which can be used over a relatively long period of time with little cleaning effort.
  • this object is achieved in a device for receiving mixed with solids liquids of the type mentioned above in that the body is closed with a loss plate with an opening.
  • the loss plate When the negative pressure is applied, the loss plate is only soiled on its side facing the interior of the body. This contamination is reliably absorbed in the body and therefore does not have to be removed manually. Contamination of the device for removing liquid is reliably avoided.
  • the object is achieved in that the cover on its side facing the receiving device has at least one seal for engagement with a loss sheet. This seal prevents the migration of solids into the space between the lid and the loss plate. The lid is therefore reliably protected against contamination. A complex manual cleaning is no longer necessary.
  • the opening is arranged in the middle of the loss sheet.
  • a uniform application of the interior of the body is achieved with negative pressure.
  • the loss sheet has a curvature.
  • the curvature is modeled on the domed shape of the known dished bottom and causes a reliable removal of the liquid. Further, the loss sheet can easily be elastically deformed upon contact with the lid due to the curvature and therefore biased. The arranged on the lid seal is then loaded with the biasing force, so that the sealing effect is improved. An impairment of the sealing effect by the elastic deformation of the loss sheet is excluded due to the curvature.
  • the opening of the loss sheet may be provided with a circumferential thickening, in particular a rib, a web or a flanging. This thickening also causes a load on the seal arranged on the cover, so that the sealing effect is improved.
  • the thickening of the loss sheet can be combined with the buckle.
  • the device according to the invention for removing liquid can be used together with a receiving device whose body is already closed with a loss plate.
  • a separate loss plate that is attached to the lid only upon removal of liquid from the exception device.
  • the cover has a further seal on its outer circumference for engagement with the receiving device. This further seal prevents the ingress of ambient air into the receiving device and the escape of solids from the receiving device.
  • the device has a cleaning device for its interior.
  • This interior communicates through the openings of the lid and the loss plate with the interior of the receiving device in connection and can therefore be contaminated by solids.
  • the cleaning device allows removal of these solids without manual assistance.
  • the interior of the device for removing liquid is formed substantially cylindrical. If the cleaning device is arranged substantially on the central axis of this cylinder, then the distance to the side walls of the interior is always the same. As a result, a good cleaning effect is achieved throughout the interior.
  • FIG. 1 schematically shows a device for receiving liquids mixed with solids, which is referred to as barrel 10.
  • the barrel 10 has a substantially cylindrical body 11 with an inner space 12.
  • the body 11 is closed with a curved loss plate 13.
  • the loss plate 13 has in the region of a central axis 15 of an opening 14.
  • the opening 14 of the loss plate 13 is surrounded by a circumferential thickening 16.
  • a device for removing liquid from a drum 10 which is referred to as a filling hood 20.
  • the filling hood 20 has a lid 21 for resting on the drum 10.
  • the lid 21 is adjoined by an interior 25, which is formed substantially cylindrical.
  • the lid 21 has an opening 24 in the region of the interior 25.
  • From the interior 25 branches off a vapor tube 22 for discharging liquids.
  • a cleaning device 26 which is arranged substantially centrally in the interior 25.
  • This seal 23 settles in the first embodiment of the loss plate 13 of a barrel 10.
  • a loss plate 13 ' can be used, which is formed separately from the drum 10 and the filling hood 20. This loss plate 13 'is attached to the lid 21 of the filling hood. Subsequently, the barrel 10 is connected to the filling hood 20. At the same time, the loss plate 13 'is sealingly received between the lid 21 and the drum 10. In the area of the openings 14, 24, the seal 23 is provided. On the outer circumference of the lid 21, a further seal 29 is arranged, which applies to the drum 10.
  • FIGS 2 to 4 show a further embodiment of a filling hood 20 according to the invention, to which a barrel 10 is attached.
  • the loss plate 13 is between the lid 21st and the barrel 10 recorded.
  • the gap between the loss plate 13 and the lid 21 is sealed by the seal 23. If a loss plate 13 is used with a curvature, the cover 21 can be pressed onto the loss plate and deform it elastically. As a result, the sealing force acting on the seal 23 is substantially increased.
  • the seal 30 is formed here as an inflatable seal and prevents the ingress of ambient air into the barrel 10th
  • the interior 25 of the filling hood 20 is subjected to negative pressure.
  • liquid evaporates and is discharged through the vapor tube 22.
  • a concentrate line 28 is provided for returning any accumulating concentrate.
  • the cleaning device 26 which has a number of nozzles 27 is used.
  • the interior 25 is formed substantially cylindrical.
  • the distance from the nozzles 27 to the wall of the interior 25 is the same over the entire length of the interior. Therefore, at all points of the wall of the inner space 25, the cleaning agent emerging from the nozzles 27 impinges with the same pressure. As a result, a reliable cleaning effect is achieved.
  • a suitable, not shown collecting device is attached to the lid 21 from below to clean the interior 25. Pollution of the environment can be reliably avoided. Of course, the cleaning of the interior 25 can take place even when attached barrel 10. A complex manual cleaning is no longer necessary.
  • the barrel 10 according to the invention and the filling cap 20 according to the invention allow a trouble-free operation with little cleaning effort over a longer period.
