Definitions

  • the invention relates to a system for drying workpieces which have been charged with a liquid medium. For receiving at least one workpiece to be dried, there is a workpiece receiving area in this system. Moreover, the invention also relates to methods for drying such workpieces.
  • drying ovens In which the workpieces are subjected to heat in order to evaporate adhering to the workpieces liquid media.
  • this drying process usually requires a great deal of energy and time.
  • workpieces for drying in industrial production are moved by one or more workpiece axes with handling robots, while blowing air is simultaneously applied to the surface of the workpieces.
  • DE 42 37 335 A1 describes a system for drying of the type mentioned initially.
  • workpieces treated with a cleaning fluid can be exposed to a vacuum in an airtight sealable chamber. By evacuating the chamber, residues of cleaning liquid adhering to a workpiece are then evaporated.
  • this system contains blowing nozzles, with which air jets are generated. Workpieces are blown off with these air jets. The cleaning liquid received in the holes and blind holes of a workpiece is thereby atomized.
  • the object of the invention is to reduce the energy required for the drying of workpieces that have been charged with liquid media.
  • This object is achieved by a plant of the type mentioned, which has a suction device and a housing in which a workpiece arranged in the workpiece receiving area are enclosed can, wherein the housing has a suction connected to the Absaugvor by a suction line suction port to generate a vacuum by sucking the suction line with the suction device to the suction port of the housing.
  • liquid media deposited on a workpiece in the housing rapidly evaporate and are thereby released from the workpiece.
  • a workpiece arranged in the workpiece receiving area and within the housing preferably causes (by means of displacement effects) a reduction in the volume of fluid in the housing.
  • the invention makes use of the fact that spaces in the form of flow channels are formed between a workpiece arranged in the housing and the housing with a clear cross-section reduced in relation to the surroundings.
  • the fluid flow in the housing is then guided in the workpiece receiving area through one or more bottlenecks, in which it is accelerated in sections on its way into the suction line and / or slowed down and / or also deflected.
  • the housing has a housing wall with at least one passage opening for a gaseous fluid through which the gaseous fluid can be sucked into the housing by generating negative pressure at the suction connection with the suction device. If a negative pressure is generated at the suction connection of the housing, a pressure gradient forms there between the at least one passage opening and the suction connection, so that a fluid flow then arises from the passage opening to the suction connection through the housing.
  • this fluid flow extends at least in sections along the workpiece to be dried. Due to the dynamic pressure dependent on the velocity of the fluid flow, the static pressure on the surfaces of the workpiece to be dried is also changed and at least partially reduced.
  • the inventors have recognized that due to the flow velocity of the fluid flow, liquid droplets deposited on the surface of a workpiece can be removed particularly effectively at such a reduced static pressure.
  • Narrow sections are preferably formed in sections between the housing and a workpiece, at which point the flow velocity of the fluid flow reaches a relative maximum, so that the desired drying effect is particularly great there. It is also an idea of the invention to direct the fluid flow in the housing through cavities of a workpiece in which the fluid flow is also locally accelerated.
  • the suction device in the system contains a vacuum container, which can be ventilated via the suction line, and an evacuation device for evacuating the vacuum container.
  • a vacuum container which can be ventilated via the suction line
  • an evacuation device for evacuating the vacuum container.
  • the system has a lent valve designed as a valve.
  • the housing surrounding the workpiece receiving area is arranged in a vacuum-tightly closable vacuum chamber. This makes it possible to pre-dry workpieces in the system by applying a strong fluid flow and then, after predrying, to vacuum drying them by evacuating the vacuum chamber.
  • a partial vacuum can be formed by applying negative pressure to the suction connection of the housing in the vacuum chamber. Setting a higher vacuum in the vacuum chamber for vacuum drying is then possible with reduced energy and time.
  • the evacuation means may include a suction pump connected to the vacuum chamber through a fluid line on the suction side. It is advantageous if the system has a suction-side communicating to the suction pump with the fluid line line for evacuating the vacuum vessel. In this way, the evacuation device can be used both for evacuating the vacuum container and for evacuating the vacuum chamber.
  • the system may have a ventilation device for venting the vacuum chamber.
  • This ventilation device preferably includes a valve which selectively releases or obstructs a flow path for fluid leading into the interior of the vacuum chamber.
  • the housing in the vacuum chamber can be designed tunnel-shaped.
  • a linear movement device for the linear displacement of workpieces through the housing from a first closable opening of the vacuum chamber to a further opening of the vacuum chamber opposite the first opening can then be provided in the housing. To this This enables the drying of workpieces in the system with short cycle times.
  • the system may also include a housing having a first housing portion which is displaceable for locating workpieces in the workpiece receiving area relative to a second housing portion of the housing. In this way, the arrangement of workpieces in the housing of the system can be simplified.
  • the invention also extends to a plant system for the industrial cleaning of workpieces with a cleaning system, in which workpieces can be acted upon by a liquid medium containing a plant for the drying of liquid medium acted upon workpieces having the features indicated above.
  • the invention also extends to a method for the drying of workpieces which have been charged with a liquid medium, in which a workpiece is arranged in a housing, and in which the workpiece by sucking gaseous fluid from the housing with a gaseous fluid flow is applied.
  • an idea of the invention is that the workpiece is placed in a vacuum chamber prior to vacuum drying in the housing. It is advantageous if the housing is at least partially adapted to the outer contour of the workpieces. In this way, the amount of fluid that must be pumped for adjusting a vacuum in the vacuum chamber and for generating a flow of fluid through the housing in the plant can be reduced.
