Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the used paint residues including rust and plaster particles must be collected to prevent them from penetrating 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 led 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.
  • the wastewater cycle required for this is complex and takes up a lot of space, especially since it takes time to settle the paint particles, which is why all the wastewater must first be collected.
  • the settled sludge is difficult to handle and therefore difficult to remove.
  • the invention is based on the object of designing a device of the type mentioned at the outset so that the separation of the color particles and the other solids contaminating the wash water from the wash water and the disposal of the color particles and the other solids can be carried out with little technical effort and in a space-saving manner .
  • 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.
  • the height adjustment enables the spray effect to be regulated.
  • the collecting filter is expediently designed according to claim 3 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. Filters have the effect that over time they become clogged with contaminants.
  • the training according to claim 4 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.
  • 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 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 are directed obliquely downward in such a way that when the spray water emerges, a force component is created 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 and is operated at a higher speed by means of a gear transmission.
  • 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 to a first gear 56 which is connected to a second gear 57 in a rotationally rigid manner.
  • the second gear 57 is connected in a rotationally rigid manner to a shaft 65 and meshes with a second internal gear 66 of a second pot 67, which is rotatable concentrically with the first pot 55 device.
  • the shaft 65 is rotatably supported in a bearing cage 68 which is rigidly connected to the housing 9.
  • the press water is supplied to the nozzle ring 2 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 and the nozzle ring.
  • 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 17 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. In the area between the sub-floor 11 and the upper floor 10, as can be seen from FIG. 1, the housing 9 is of spiral design and forms one Discharge channel 22 for the contaminated wash 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.
  • 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 a bead or flange 57 (FIG. 3) in the manner shown, 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 57.
  • a hook 58 of a quick-release lever 60 articulated on an axis 59 can be placed on this bead.
  • the axis 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.
  • the bead 57 can be pulled through the hook 58 against a sealing flange 63 provided on the connecting piece 23.
  • 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 the 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.
  • a piece of pipe 28 extends, which is connected to a hollow cylinder 29.
  • the pipe section 28 (or the hollow cylinder 29) extends into a sleeve 30 (FIG. 5) fixed to the upper floor 10, is supported there in a self-aligning bearing 31 and is enclosed at the lower end of the sleeve by an O-ring 31a which is in a annular recess 32 of a sleeve-fixed abutment ring 33 is mounted.
  • the sleeve 30 is vertically adjustable in a flange ring 34 and can be locked in place by means of screws 35.
  • the flange ring 34 is fastened to the upper floor 10 by screws 36, not shown.
  • the undercarriage of the device has two longitudinal spars 37, 38 which are cranked downward, the central part 39 of which runs at the height of the annular chamber 13.
  • extending tabs 40 are attached perpendicular to the central part, on which a U-shaped bracket 41 is fixed is placed, the side legs of which are connected to the housing 9, for example by welding.
  • vertically extending tabs 42 are fastened, on which angle pieces 43, 44 are fixed, which are connected to the housing 9 at their free end edges.
