Definitions

  • the invention relates to a housed, with permanent Vacuum pickling line with at least one Pickling bath, with at least one lock gate in the enclosure for the introduction and removal of pickling material and an air supply and a suction.
  • DE-A-36 35 525 a system for pickling is disclosed where several pickling tanks side by side in one Installation room can be set up, which at the same time as serves additional treatment basin and one not tight cabin is put over it.
  • the revealed plant cabin is equipped with a suction system kept under vacuum by the difference the suction quantity and the permanently open inflow and formed Curtains. Furthermore, the system cabin has one their entire length slit through which the Operating lever for the workpiece carrier for the to be treated Workpieces is guided. This slot is with one Provide cover that have individual recesses, which enable the workpiece carrier to be raised and lowered. With continuous extraction of a certain exit area is produced. Closing the in and Outlet openings are made by apron-like strips Air volume leads to a tracking of air.
  • the object of the invention is to create a housed Pickling line, which has the disadvantages of known pickling lines or pre-treatments do not adhere and both in environmental and economically a safe one and ensure simple operation.
  • the object is achieved according to the invention in that that the lock gate is designed as a sliding gate and that the air supply is arranged in the area of the sliding gate is.
  • the pickling plant By arranging the air supply in the area of Sliding gate is used in cooperation with the suction the lock gate opening towards the inside of the room the pickling plant is an essentially turbulence-free directed one Flow generated before, during and after opening of a sliding gate the inflow of the supply air in the same Direction supported.
  • the arrangement of the suction points is included not critical; you can drive to a lock gate, the regulation of the vacuum in the pickling line he follows.
  • the arrangement of the suction points is included not critical; they can be at a lock gate opposite But also place at any other Desired positions of the pickling system can be provided. The Formation of an inward flow in the on The area adjacent to the lock gate remains unaffected.
  • Another feature of the invention is that at the bottom End of a lock gate opening a substantially horizontal, inwardly projecting plate is arranged.
  • An embodiment of the invention is that the air supply is integrated in the sliding gate.
  • the air supply is a supply air blind. So that's up very simple way of inflowing the supply air while holding it back the outflow of air from the pickling or pre-treatment room guaranteed.
  • the pickling plant is further according to the invention characterized in that the lock gate opening laterally from inside protruding plates is limited. This will an inwardly extending tunnel is formed by means of which in a safety-enhancing manner is a possible one Emission of emissions through the open lock gate is effectively prevented.
  • Another embodiment of the enclosed pickling plant of the type mentioned at the bottom an essentially horizontal, arranged inwardly protruding plate, according to the invention in that in or within the enclosure on both sides of the lock gate opening, essentially extending diagonally across the height of the lock gate internally aligned, facing air supply nozzles are arranged.
  • the air supply nozzles at an angle ⁇ between 25 ° and 60 ° aligned to the lock gate level. Furthermore, the invention provided that the flow lines from air exiting the air supply nozzles in the area above the Cross the plate located under the lock gate opening. This is a reliable prevention in an optimal way of emissions leakage reached. According to the invention are the air jets emerging from the air supply nozzles aligned essentially horizontally.
  • a further embodiment of the invention is thereby characterized in that the air supply nozzles in essentially vertically aligned air supply ducts are arranged, with which a particularly simple and effective formation of a Supply air curtain inside the lock gate opening achievable and thus the inflow in a very simple manner the supply air while preventing the outflow of air the pickling or pre-treatment room is guaranteed.
  • Another embodiment of the invention exists in that the air supply duct at its upper end with the enclosure ceiling is sealed.
  • a feature of the invention is also that the air supply channels arranged on both sides of the lock gate opening are connected below the plate, an air supply line in the connection of the air supply channels opens.
  • Air supply nozzle (s) provided.
  • the air can run across the entire width or just in the upper corners of the lock opening in small quantities to be blown.
  • Fig. 1 is a housed Pickling plant without an enclosed ceiling with closed Lock gates
  • Fig. 2 with a housed pickling plant an open and a closed lock gate without integrated air supply
  • Fig. 3 shows an embodiment a lock gate opening
  • Fig. 4 shows another embodiment a lock gate opening
  • Fig. 5 shows a third embodiment show a lock gate opening.
  • the pickling system shown in FIGS. 1 and 2 or Pretreatment includes enclosure walls 1, which advantageously built from acid-proof wall panels and to the emission room are laminated diffusion-tight. As well there is the one not shown for reasons of clarity Acid-resistant panel ceiling.
  • lock gates 3, 4 arranged, one of which preferably as an entrance gate and the other serves as an exit gate for the pickling material.
  • the Lock gates 3, 4 are advantageously as sliding gates educated.
  • the pickling material is not shown Crane retracted and extended, being for the crane ropes on which the pickling material hangs, sealed by special sealing systems Bushings in the ceiling and each provided in the upper limit of a lock gate opening 5 are.
  • the lock gates 3, 4 supply air blinds 6 integrated.
  • air blinds 6 are on one or Exhaust venetian blinds 7 arranged in several places. If too additional air inlets at other parts of the enclosure can be provided, so in the under permanent Vacuum pickling plant by arranging the Supply air blinds 6 in the lock gates 3, 4 and Exhaust blinds 7, for example in the opposite Wall 1 of the housing a pronounced directional air flow from the lock gates 3, 4 to the exhaust air blinds 7 generated.
  • lock gates 3, 4 Supply air blinds for supplying air to the pickling system equip.
  • the lock gates 3, 4 can also be used appropriate air flaps or the supply air can also only be provided by in lock gates 3, 4 Inflow openings; it is essential that the air supply is integrated in the lock gate 3, 4.
  • While a lock gate 3, 4 is open, from outside additionally by means of one or more, in the upper one Third of the lock gate opening 5 arranged air supply nozzles 10 air is blown in a small amount. Thereby there is also a partial outflow of air from the pickling or pre-treatment room prevented.
  • the plates 8 and 11 form one tunnel-like boundary protruding from the interior a lock gate opening 5, as can be seen from FIG. 4 is.
  • Air supply duct arranged in the form of a tube 12.
  • the Tube 12 is with one extending along its length Blow slot 13 provided, from which the air supplied emerges diagonally inwards facing each other. This occurs the supplied air at an angle ⁇ of 25 ° to 60 ° Lock gate level from the blow slots 13.
  • air jets 14 emerging from the blow slots are aligned essentially horizontally.
  • the crossing points the exiting from the blow slots 13 In any case, air jets 14 must be above plate 8 his.
  • the tubes 12 can either from above or from below be fed with air, either fresh air or air can be out of the drying oven. Depending on whether from above or If air is supplied from below, the situation is different To close the end of the tube 12.
  • the two pipes 12 can either be on a shared line that connects to both Pipes 12 can be fed branched or each pipe 12 can can be supplied with air separately.
  • the tubes 12 are on the one hand with the ceiling of the housing, on the other hand connected to the plate 8 so that achieved a mechanical seal up and down becomes.
  • the air can pass through that provided in the tubes 12 Blow-in openings blown in by a separate fan become.
  • the supplied air can also be by-pass air from Be a drying oven.
  • the air inlets can be the blow slots 13, but just as well over the length the tubes 12 are arranged bores.
  • air can additionally flow from be blown outside.
