Definitions

  • the invention relates to a method according to claim 1 and an apparatus according to claim 5.
  • Facades that are contaminated by environmental influences, such as the deposit of soot particles, or by undesired application of paint, are cleaned by mechanical grinding processes, but preferably with a dry jet.
  • the blasting material preferably consists of tiny, round, elastic glass beads, which are sprayed onto the surface to be cleaned with a slight twist, thereby erasing the layer of dirt.
  • the blasting material and the dirt particles are extracted by a vacuum system and fed to a dedusting system, which separates the blasting material from the dirt.
  • the blasting and suction are carried out in a space that is closed to the outside and lies on the only open side close to the surface to be processed.
  • the cleaning staff must check the effect of the jet in order to direct the jet onto soiled areas until the desired cleanliness is achieved.
  • the first solution provides that the locked room is large enough to accommodate the cleaning staff.
  • the second solution chooses the size of the enclosed space so small that it can be held in the hand of the cleaning staff and guided over the surface.
  • the first solution has the disadvantage that the work space that receives the cleaning staff, which lies with its open side on the facade and is moved in sections, is very large and therefore extremely heavy.
  • a crane truck is used to move it along the facade, and the work area is suspended from its jib.
  • the hanging type of attachment is for a manned Work area only permitted with a special and very expensive crane truck.
  • the high concentration of dirt and jets in the work area is a danger to the eyes and the respiratory tract of the cleaning staff.
  • the health risk can only be reduced to an acceptable level by wearing protective goggles, protective masks and protective suits.
  • the protective measures do not offer complete protection and are also a hindrance when working.
  • the second solution has the disadvantage that the enclosed space or work box, which receives the jet nozzle and the suction connection, has to be held by hand and guided along the surface.
  • the necessary freedom of movement along the surface does not allow a satisfactory seal on the side open to the surface, so that dirt particles and blasting material escape and lead to an impairment of the environment, in particular the health of the cleaning staff.
  • the impact of the cleaning jet on the surface cannot be observed in the closed room, so that the targeted treatment of dirt spots is not sufficiently possible.
  • To check the cleaning effect of the work box must also be moved first, so that the cleaning process is very cumbersome.
  • the object of the invention is now to describe a method and a device which enable efficient cleaning in that the cleaning personnel have the necessary visual contact with the cleaning jet and the necessary manipulability of the jet, without the environment and the cleaning personnel simultaneously being exposed to increased dirt - and blasting material concentration are exposed.
  • a treatment area is used with at least one suction opening, which is at least partially open both on a contact side against the surface to be processed for jet cleaning and on a front boundary surface opposite the surface for manipulation and viewing purposes.
  • the treatment area is at least partially closed off from the outside by at least three, but preferably four, lateral boundary surfaces which are arranged transversely to the surface and to the front boundary surface.
  • blasting material and dirt particles are prevented from escaping by a sealing device which surrounds the opening on the contact side and connects tightly to the surface.
  • a gas flow is excited at least in a part of the treatment area, essentially parallel to the surface.
  • the gas flow preferably comprises at least one gas or air curtain which starts from an inlet device and extends into the region of the at least one suction opening.
  • the inlet device is arranged at least along a lateral boundary surface, comprises at least one line nozzle and / or several point nozzles and is fed by compressed gas, but preferably compressed air.
  • the arrangement of the inlet device and the at least one suction opening is chosen in particular in such a way that the air curtain extends along the front boundary surface and closes the working opening against the escape of air that is located between the curtain and the contact surface.
  • a blasting material suction flow is preferably stimulated between the air curtain and the surface to be cleaned or the contact side. This flow is created at least in part by entering the cleaning jet and suction. However, it is preferably reinforced or evened out by inflowing false air, but possibly also by injected gas, in particular compressed air.
  • the flow pattern which is preferably aimed for essentially provides a single main flow direction essentially parallel to the surface in the entire treatment area. Large vortices with significant backflows must be avoided.
  • the flow velocity is maximum in the center of the air curtain and decreases on average towards the surface.
  • the flow in the exit or jet area of the cleaning jet is essentially only in the direction of the jet.
  • this is actually a local disturbance of the global flow in the treatment area.
  • the cleaning jet is directed against the surface. The jet flow is destroyed as soon as it bounces off the surface, and the remaining local flow components and turbulence oriented transversely to the flow through the treatment area are carried away by the global flow.
  • the air curtain and the parallel suction flow are formed by the interaction of the incoming compressed air, and possibly the false air, and the suction power and the arrangement of the at least one suction opening.
  • the inflowing air, compressed air and / or false air enters the treatment area in the region of a first lateral boundary surface and is extracted through at least one suction opening in the region of a second lateral boundary surface, the first and the second boundary surface are arranged opposite each other.
  • the suction volume throughput is set in this way or, if necessary, by a control device regulated so that it essentially always corresponds to at least the sum of the uncompressed volume input through the inlet device and the jet nozzle. However, it is preferably larger at least at times and discharges false air. False air can also enter the treatment area between the sealing device, which surrounds the opening on the contact side, and the surface.
  • At least one physical variable such as the pressure or a variable dependent on the concentration of the blasting material
  • at least one sensor In a zone of the treatment area that is close to the surface and away from the at least one suction opening, there is a risk that a high particle concentration and thus poor visibility will occur due to a suction flow that is too weak.
  • the effective visibility can be detected using an optical sensor, for example.
  • Information about the flow situation is recorded by means of pressure measurements.
  • the suction power and / or the inflow of false and / or compressed air can be regulated according to the measured values.
  • the cleaning staff can guide the jet nozzle unhindered through a working opening in the treatment area and at the same time observe the effect of the cleaning jet. Neither the personnel nor the environment are affected by blasting material and / or dirt particles.
  • the device required to carry out the method is light and can be attached to a standard lifting platform for cleaning facades, for example on a work platform that can be positioned in a large area by means of a swiveling telescopic arm. Since the treatment area is aligned essentially vertically when cleaning facades, the air inlet device is preferably at an overhead opening and the at least one suction opening arranged on an underlying lateral boundary surface. As a result, the blasting material is moved not only by the flow in the treatment area but also by gravity against the at least one suction opening.
  • the cleaning jet nozzle is fed via a blasting material line from a compressor located on the floor, a control line from an actuating handle at the blasting nozzle to the compressor preferably being provided for controlling the cleaning jet or the compressor.
  • the compressed air required for the air curtain and possibly for the blasting material suction flow is led from the same or a further compressor via a compressed air line to the inlet device.
  • a further line preferably a flexible hose, which comprises a metal spiral and a plastic jacket, is provided.
  • the facade cleaning can already be carried out by a single person.
  • the labor costs and equipment costs are extremely small.
  • the quality of the workplace is significantly better than that of the well-known closed work rooms and the motivation of the cleaning staff can be expected to be greater.
  • a treatment area according to the invention is advantageous, new and inventive not only together with a cleaning jet. Even in the case of mechanical processing of a surface in which particles are released, for example when grinding the surface with belt or disk grinding machines, it is expedient to use a treatment area according to the invention with an air curtain and a suction device. The release of dust into the environment can be avoided and the personnel can be protected.
  • the application of the method according to the invention is not limited to the cleaning of facades, but can for example can also be used in workshops for machining workpiece surfaces. This prevents dirt and / or blasting particles from escaping into the workshop.
  • the surface to be machined can be arranged on a contact surface or inside the machining area. If it is arranged inside, an end wall is provided instead of the contact opening.
  • the treatment area is formed by a processing chamber with only one working opening.
  • the known processing chambers are essentially completely closed to the outside and only gloves attached to hand openings are provided in the processing chamber for guiding the implement. With these devices according to the prior art, the freedom of movement of the cleaning staff is severely restricted.
  • a treatment area according to the invention now has the great advantage that manipulation through the working opening is only marginally possible, without substantial amounts of dust escaping from the treatment room.
  • a cuboid treatment area 2 adjoining a facade 1 is at least partially delimited by a housing 3.
  • the housing 3 essentially comprises a frame 4 and lateral edge surfaces 5 which are fastened to it and oriented transversely to the facade, and at least one sealing element 6 which adjoins the lateral edge surfaces and lies tightly against the facade.
  • a working opening is provided in a front boundary surface 7 of the housing 3, which lies opposite the facade 1.
  • the housing 3 is fastened to a position-adjustable work platform 8, from which the cleaning personnel 9 can direct a jet nozzle 10 or another working device through the work opening in a targeted manner within the at least one sealing element 6 to points of the facade 1 to be worked.
  • the working platform 8 is preferably attached to the free end of a telescopic arm 12 of a lifting device 13 which can be pivoted about a horizontal axis 11.
  • the cleaning staff 9 can adjust the position of the work platform 8 and thus the treatment area 2 via a control panel 14 along the facade 1 and can clean the entire facade 1 in sections.
  • the blasting material required to generate the cleaning jet is guided by compressed air through a compressor and blasting device 15, which is parked near the lifting device 13, via a blasting material line 16 to the blasting nozzle 10.
  • a control line 17 is arranged parallel to the line 16 and connected to the compressor of the device 15 via a control unit 22 and a compressor cable 23. The control line 17 enables the cleaning staff 9 to regulate the compressor of the device 15 and thus the jet by means of an actuating element connected to it.
  • the blasting material is disposed from the treatment area 2 by at least one on the lower lateral boundary surface 5 Suction opening and a flexible hose adjoining it are sucked to a recycling unit 19.
  • the recycling unit 19 essentially comprises a suction unit and a dedusting device which separates the blasting material from the entrained dust. The blasting material reaches the device 15 through a line 20 from the recycling unit 19 for reuse in the cleaning jet.
  • a compressed air line 21 leads from the compressor of the device 15, or possibly from a second compressor, to the housing 3.
  • the compressed air supplied therein is used to form an air curtain and, if necessary, to amplify a blasting material suction flow in the treatment area 2.
  • the control unit 22 is also connected to the recycling unit 19 via a connecting cable 24.
  • the housing 3 preferably comprises two vertical frame parts 4a adjoining the platform 8, which are connected at the upper and lower ends to frame parts 4b which lead horizontally against the facade 1. Between the upper and optionally also between the lower parts 4b, horizontally aligned frame parts 4c are provided parallel to the facade 1. Between the lower parts 4b, only a grate 27 is optionally provided and then a funnel 28 is provided at the bottom. Since the funnel 28 is connected to the flexible hose 18 and thus to the suction unit, the passage openings of the grate 27 form the suction openings 29. The grate 27 retains large foreign parts, such as tools, in the treatment area.
  • An upper boundary surface 5a is fastened over the upper frame parts 4b and 4c. Laterally on the frame parts 4a and 4b, lateral boundary surfaces 5b are arranged, so that the treatment area 2 is delimited laterally, above and below by the wall parts 5b, 5a and 27. At least one sealing element 6 adjoins these wall parts on the side of the facade 1 around a contact opening 30, which leaves access from the treatment area to a facade cutout.
  • the embodiment according to FIG. 2 comprises two round hollow profiles made of elastic material, such as rubber or plastic, arranged side by side.
  • an inclined seal surface 54 is provided in order to prevent particles from remaining on the seal 6 associated with the lower boundary surface.
  • a sealing device 6 with at least one compressed air-fed air chamber system with at least one but preferably two feed openings and optionally at least one pressure valve preventing the bursting of a sealing element is used.

So that the seal 6 also bears tightly around the contact opening 30 around the contact opening 30, even in the case of strongly curved facade parts, in addition to various sealing profiles, bellows and / or lamella and / or brush-like sealing elements can also be used. Another advantageous embodiment of the sealing device 6 is described further below with reference to FIG. 5.
  • At least one suction opening 29 ' can also be provided in the region of the lateral boundary surfaces 5b.
  • at least one suction channel 52 running essentially parallel to the surface is slidably attached to guide elements 53 with a slot opening 29 ', preferably along the lateral edge surface.
  • the provision of suction openings 29, 29 ′ essentially around the contact opening 30 can prevent large amounts of dust and jet particles from escaping through the sealing device 6 in the event of poor sealing.
  • the Suction channels 52 lead suction lines 52 ′ to a connection device to the flexible hose 18 or directly to the recycling unit 19.
  • the front boundary surface 31 opposite the contact opening 30 or facing the work platform is preferably closed off in a lower region by a front plate 31a.

  • An emerging cleaning jet 32 strikes the facade and removes the unwanted layer. The blasting material and the dirt parts flow away from the facade 1 and at least partly come against the suction openings 29 below due to the suction and gravity.
  • an air curtain 33 is provided in the treatment area 2 directly inside the working opening 31b over the entire width of the opening.

  • the air nozzles 34 are fed by the compressed air line 21, which preferably leads in the housing 3 along a frame part 4a, and are optionally designed as Venturi nozzles.
  • No flow structure with large vortices should form between the air curtain 33 and the contact opening 30, but rather a blasting material suction flow that is as uniform as possible.
  • incorrect air and / or compressed air may have to be introduced into the area near the facade behind the air curtain 33.
  • at least one false air opening 35 can be provided in the upper boundary surface 5a.

  • the inlet nozzle 36 is arranged in the region of the upper boundary surface 5a between the air nozzle 34 and the contact opening and, together with the suction, stimulates a uniform blasting material suction flow.
  • the nozzle 36 can consist of several point or line nozzles, or it can consist of a surface nozzle, for example made of porous material.
  • the type of formation of the nozzles 34 and 36 and the suitable distribution of the compressed air to the nozzles 34 and 36 by means of the distribution device 37 can stimulate a desired flow structure in the entire treatment area 2.
  • a distribution control can be provided, which regulates the distribution depending on the operation and is connected to the control unit 22, for example, via the control line 17.

If necessary, the first circulation flow could also be oriented horizontally. It can thus be seen that a large number of embodiments according to the invention can be provided to suit the particular cleaning problem.
  • Fig. 5 shows a preferred embodiment of the sealing device 6, which ensures a good seal of the treatment area 2 from the outside even in facades with a plurality of elements protruding from the plane of the facade, such as ledges and shoulders.
  • the inventive idea on which the solution is based is that in the above contact surface 55 of the sealing device 6 the transmission of surface forces is to be restricted to small sub-areas.
  • a contact layer 56 preferably made of elastic foam, against the contact surface 55 must be divided into closely adjoining individual foam extensions 57, each of which can be pressed together individually. No surface forces are transmitted between different extensions 57 and the contact surface 55 can thus abruptly adjoin facade heels 58.
  • this would also be formed continuously via shoulders 58 protruding at right angles from the facade 1, so that there would be openings on both sides of such shoulders 58 between the facade 1 and the sealing device 6.
  • the extensions 57 are arranged at least in a longitudinal path 59 essentially along the sealing device 6 or around the contact opening. Since an extension 57, which is just in the area of a shoulder edge, does not lie close to this, as shown in FIG. 5b, in particular a plurality of longitudinal tracks are shown 59 are preferably arranged next to one another such that the protruding extensions 57 of different tracks are offset from one another. If appropriate, provision is also made for the extensions 57 of different webs 59 to have different lengths in the longitudinal direction of the web. As a result of the offset and the different length of the extensions 57, extension sides occur at short intervals, so that no or only very small openings arise in the case of shoulders.
  • the contact layer 56 can optionally also be constructed like a tube. A low pressure is built up on the inside, so that the chamber-shaped extensions 57 receive the desired deformability.
  • the contact layer is preferably attached to a tube body 60 belonging to the sealing device 6 and filled with compressed air, in particular high pressure.
  • the tubular body 60 like the contact layer 56, can consist of different sections.
  • a Velcro fastener system is preferably provided for attachment. If necessary, a Velcro fastener is also provided for fastening the at least one hose body 60 to the boundary surface 5.
