Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the used paint residues including rust and plaster particles as well as the water masses containing them must be collected in order to prevent their penetration into the groundwater, the sewage system or the harbor basin.
  • a device of this type is known (DE-PS 32 29 720), or the like for cleaning the surfaces of ship hulls, lock gates provided with an underwater paint. is used, and in which the discharge channel opens into a cyclone or into a cleaning unit consisting of several cyclones, from which or from which the pre-cleaned water is directed into a water tank provided with several settling tanks.
  • the dirt particles drawn off from the lower reaches of the cyclone or cyclones go into a collecting container.
  • a large number of lines and containers are necessary which make the system clumsy and heavy.
  • the particles are sucked in, as is known, by a pump, which is connected downstream of the cleaning unit.
  • the pump output must be relatively large. An additional energy supply for its drive is also required for the pump. At the same time, however, the spray nozzle, e.g. driven by the recoil, braked to optimize their effect on the surface to be cleaned.
  • the invention is based on the object of designing a device of the type mentioned in such a way that the The effect of the pump is achieved with little technical effort while saving additional energy and reducing the number of components and lines, measured using a conventional system.
  • This object is achieved by the characterizing features of claim 1.
  • the advantages thus arise not only in terms of investment, but also in the operation of the device, and the contaminants can be disposed of easily and quickly.
  • the spray housing can have a spiral shape.
  • the liquid with impurities is more effectively conveyed into the collecting filter by the pump, which now acts as a pressure pump and is arranged in the housing.
  • a height adjustment according to claim 3 enables the control of the spray effect.
  • the collecting filter is expediently designed as a bag for easier disposal, although it would be entirely possible within the scope of the invention to use, for example, disk-shaped filter membranes in a filter housing.
  • the disadvantage of filters is that they become clogged with contaminants over time. These impurities will be low if the device according to the invention is used, for example, to apply coatings, for example lacquers, to the surface to be sprayed, but the main area of application is in cleaning the surface, which naturally results in a large amount of such impurities.
  • the training according to claim 8 is advantageously made. It has been shown that when coarse and fine impurities are caught in a single filter, the fine particles clog the spaces between the coarse particles and thus result in a synergistic effect, albeit in a negative sense. One separates against it Coarse and fine parts separately or one after the other, so there is enough space in the coarse filter between the coarse impurities to allow liquid and fine impurities to pass through, which are then caught in the fine filter and do not clog it so quickly because of their smaller amount.
  • the device shown in FIGS. 1 to 4 for cleaning surfaces 0 provided with a paint coat has a nozzle ring 2 consisting of four spray nozzles 1 arranged at an angular distance of 90 °, which is rotatably mounted about an axis of rotation 3 .
  • Pressed water is fed to the spray nozzles through cranked pipes 4.
  • the spray nozzles 1 are directed obliquely downwards in such a way that a force component arises when the spray water emerges, which forces the nozzle ring 2 to rotate about the axis of rotation 3.
  • the pipelines 4 open into the interior of a hub 6, to which the press water is fed.
  • Two pipes 4 are connected to each other by a stiffening strut 7.
  • blades 8 of a blade wheel are fastened, in which the blades 8 are arranged at an angular distance of 90 °.
  • the blades 8 of the paddle wheel are inclined at an angle to the direction of rotation.
  • the nozzle ring 2 and the paddle wheel form a structural unit which is arranged in a housing 9 in a height-adjustable manner.
  • the blades 8 are driven via an internally toothed gear transmission 54, the details of which can be seen in section in FIG. 2b.
  • the blade rotor 8 is separated from the nozzle ring 2 in this variant and is operated at a higher speed by a gear ratio.
  • the rotation of the nozzle ring 2 is transmitted via a first pot 55 connected to it in a rotationally rigid manner with an internal toothing 64 to a first gear 56, which is connected to a second gear 57 in a rotationally rigid manner.
  • the second gearwheel 57 is connected in a rotationally rigid manner to a shaft 65 and meshes with a second internal gearwheel 66 of a second pot 67, which is rotatably mounted concentrically on the first pot 55.
  • the shaft 65 is rotatably supported in a bearing cage 68 which is rigidly connected to the housing 9.
  • the press water supply to the nozzle ring 2 takes place as in the device according to FIG. 2.
  • the second pot 67 carries the blades 8 on its outside 69.
  • the housing 9 has an upper floor 10 and a lower floor 11.
  • the underbody is provided with a circular opening from which a cylindrical annular chamber 13 extends outwards. This annular chamber delimits the lower opening 14 of the housing.
  • the spray nozzles 1 rotate in the annular chamber 13 about the axis of rotation 3.
  • the central axis 15 of the annular chamber coincides with the axis of rotation 3 of the impeller 8 and the nozzle ring 2.
  • a brush seal (18, 19 in FIG. 4) is arranged on the free edge of the edge web 16 of the annular chamber 13 and is supported on the surface 0 to be cleaned during operation of the device.
  • FIG. 1 The structural design of the brush seal results from FIG.
  • two concentric brush seals 18, 19 arranged at a radial distance are provided.
  • Fastening legs 20 are connected to the edge web 16 by screws. These fastening legs are parts of profile rings which have a U-shaped anchoring groove 21, in each of which a brush seal is fixed.
  • the paddle wheel is arranged in the space of the housing 9 above the underbody 11.
  • the housing 9 In the area between the underbody 11 and the upper floor 10, as can be seen from FIG. 1, the housing 9 has a spiral shape and forms a discharge channel 22 for the contaminated washing water. This washing water is pressed into the discharge channel 22 by the blades 8.
  • the paddle wheel acts as a brake for the nozzle ring, which works on the principle of Segner's water wheel.
  • the discharge channel 22 merges into a nozzle 23, at the opening edge of which a collecting bag 24 is fixed for the color particles and other solids contained in the wash water is.
  • This grass-catcher is made of a water-permeable material.
  • a filter bag 25 is also attached to the opening edge of the nozzle 23, which surrounds the collecting bag 24. This filter bag has a small pore size or small mesh sizes, so that the filtered water escaping to the outside can be used again to operate the cleaning device and can be fed back to the spray nozzles as press water.
  • a quick-release fastener is expediently provided for releasably attaching the filter 24, 25, which, for example, engages in the manner shown on a bead 63a or on the flange 63 (FIG. 3), which can be attached, for example, directly to the edges of the filter bags 24, 25.
  • Each of the filters 24, 25 advantageously has its own such bead 63a.
  • a hook 58 of a quick-release lever 60 articulated on an axle 59 can be placed on this bead.
  • the axle 59 is seated on a short lever 61 which can be rotated in a manner known per se about a fixed bearing 62 and thus locks itself when the dead center is exceeded.
  • only one lever 60 is shown, several of them can be distributed over the circumference of the nozzle 23. In any case, the bulge 63a can be pulled against a sealing flange 63 provided on the connecting piece 23 by the hook 58.
  • the filtered wash water is collected by a funnel 26, which is expediently arranged underneath, and fed into a return line which conducts a line 27 starting from the funnel 26 to a process water tank 72 and from there a pump line 70 for high-pressure, e.g. from 1000 to 3000 bar, the press nozzles 1 supplied press water.
  • High-pressure pump 71 is provided in line 70.
