Definitions

  • the invention relates to a vacuum cleaner for operation in combination with an insulator.
  • insulators are used to protect the employee from highly effective products or to protect the product from contamination.
  • Each activity in the isolator is carried out via gloves.
  • When working in the isolator it may be necessary to remove solid, dry impurities from machines prior to basic cleaning, to remove product deposits in a machine during intermediate cleaning, to pick up spilled material or to pick up broken glass containers.
  • vacuum cleaners are used for these tasks. In an insulator, this is not readily possible because an insulator is operated in positive or negative pressure.
  • Expensive installations are known from the prior art, which allow the use of vacuum cleaners in the insulator.
  • isolators are operated in overpressure or underpressure mode. If a commercially available vacuum cleaner is connected to the isolator, the pressure level in the isolator breaks down when the vacuum cleaner is switched on. In addition, it can not be guaranteed that all solids are retained in the vacuum cleaner filter and do not reach the atmosphere.
  • the DE 10 2007 031 611 A1 describes a cleaning unit for an insulator in which the vacuum cleaner is integrated in a beta box and is docked via a lock or a rapid transfer port to the insulator.
  • the socket for the vacuum cleaner is installed in the wall of the lock or the beta box so that it can be connected to the power supply in every room.
  • a disadvantage of this arrangement is that it can not find application when the insulator is to be designed explosion-proof, then a commercial vacuum cleaner can not be integrated into the insulator. It is also provided in this solution to dispose of the vacuum cleaner after each use as a whole.
  • the invention is therefore based on the object to provide a solution which makes it possible to operate a commercial vacuum cleaner in combination with an insulator without affecting the operating conditions of the insulator.
  • the object is achieved in that a commercial vacuum cleaner is placed outside the insulator, the vacuum cleaner nozzle is kept in the insulator, the hose is passed through a filter in the insulator to the vacuum cleaner and the exhaust air of the vacuum cleaner is led back into the insulator.
  • Such a structure allows the use of a commercially available vacuum cleaner, even if the insulator interior is ex-protected.
  • Commercially available vacuum cleaners are cheaper than vacuum cleaners in Ex-execution. Since in the embodiment of the invention sucked by the vacuum cleaner air is returned to the insulator, there is no problem to maintain the pressure level in the insulator, also can not lead to contamination of the atmosphere by poorly deposited product. In the transition from the insulator to the environment, the sucked air is passed through a filter.
  • the filter is designed as a particulate filter to typically H14 and can be changed easily and without contamination.
  • the invention thus makes it possible to operate a commercially available vacuum cleaner with reasonable effort in combination with an insulator and to facilitate the work in the insulator substantially.
  • a further advantage is that a vacuum cleaner unit can be used on various insulators. If necessary, the filters, vacuum cleaner hoses and nozzles can also be made in pharmaceutical grade material.
  • FIG. 1 shows an insulator with the inventively designed device for sucking.
  • the insulator is designated, which has depending on the operating mode in the interior of an overpressure or negative pressure.
  • the air budget is controlled by fans (not shown) outside of the insulator (1) or ensured by an in-house exhaust air.
  • the supply air and exhaust air of the insulator (1) is passed through the filters (2) and (3) to ensure that the ambient air does not contaminate the atmosphere in the insulator (1) or that substances from the insulator (1) in the ambient atmosphere be dissipated.
  • a suction hose (4) with nozzle (5) is provided, with which material can be sucked up in each area of the insulator (1).
  • the material may be a particulate product which is processed in the insulator (1), either because it has been spilled during handling, or because a cleaning of the machines arranged in the insulator (1) takes place.
  • the sucked up material is led via a hose (4) into a product filter (6), to which the hose (4) with nozzle (5) is detachably arranged.
  • the product filter (6) absorbs the sucked up material so as not to stress the downstream HEPA filters (8) and (9).
  • the product filter (6) can be exchanged or emptied independently of the HEPA filters (8, 9).
  • the two HEPA filters (8, 9) function according to the push-push principle, ie a possibly contaminated filter element is pressed by inserting a new filter element (from the clean side) into the isolator (1) and disposed of there. He can be changed so contamination free.
  • conventional filters can be used, as they are used, for example, after mills for receiving the product when it is driven directly into the filter.
  • the filtered particle-free air is sucked on commercially available hoses (10) -alternatively in pharmaceutical grade- from the commercial vacuum cleaner or blower (11). Since the air is free of particles and the vacuum cleaner or the blower (11) is not placed in a particle or dust loaded insulator, a commercial vacuum cleaner (fan) (11) can be used.
  • the vacuum cleaner (11) must not be selected in the majority of applications in explosion-proof design, moreover, he must have no special Abscheideamine. This is naturally reflected in lower costs.
  • the filter (11) serves as a safe barrier between the insulator interior and the outside area when the vacuum cleaner is not connected.
  • the air required for vacuuming is recirculated in the arrangement according to the invention and thus does not affect the air balance and the underpressure or overpressure operation of the isolator. If the air were not returned, the air budget of the isolator would be affected, which could compromise the protective function of the isolator, e.g. Leaks over seals or bursting of a glove
  • the components product filter (6) with inserted hose (4) with nozzle (5), HEPA filter (8) and (9), the filter (13) are installed in a lock container (7), thus the device is universally applicable.
  • the system can thus be docked and used for cleaning purposes on the insulator (1).
  • the accessories - hose (4) and nozzles (5) - disappear in the lock container (7), which can also be removed if necessary.
  • the components which are arranged in the lock container (7) can alternatively also be installed as a fixed installation directly in the insulator wall.
