Definitions

  • the invention has for its object to provide a device for cleaning a sluice closed channel cross section of such non-floatable debris that can work in the sewer itself and the mentioned deposits can be safely lubt and completely even at a considerable extent be ⁇ with the help and which enables largely automatic operation in the Siel.
  • a device which is characterized above all by a movable on the inner wall of the sieve, which removes the deposits from the wall of the sieve, in the direction of travel engaging the deposits with a guiding surface that rises counter to the direction of travel, by an apex at the apex of the Guide surface subsequent inlet for the lifted good, the guide surface the Siel cross-section to Schei tel basically fills, and further by a discharge space arranged below the inlet and under suction pressure, to which a hydraulic conveying device is connected.
  • This device takes into account the difficult conditions described, can be operated in the Siel itself, taking into account the flowing Siel fluid, and is simple and robust.
  • the peeling tool is moved with the device in the direction of flow of the pile and lifts the deposits lying on the pile sole. These dissolved deposits are fed to the inlet, enter the discharge space and are then removed by the hydraulic conveyor.
  • This hydraulic conveying device can then be connected in a suitable manner to the other discharge devices of the overall system. Due to the suction pressure of the hydraulic conveying device, the flow of fluid from the bed, which flows through the bed to the inlet, also entrains the bed of sludge formed from the deposits.
  • the peeling tool with the other devices can be moved in the flow direction of the board by suitable drive means arranged outside or inside the board, the hydraulic conveying device adapting to the respective travel paths.
  • the required feed and discharge devices are easy to insert through the successive shafts of the pile.
  • the device can also remain in the Siel at rest, e.g. at night, which makes work easier.
  • the inlet is closed by a sieve and a collecting basket for the oversize is arranged after the hydraulic conveying device.
  • a collecting basket for the oversize is arranged after the hydraulic conveying device. This ensures that only those grain sizes are fed to the hydraulic conveyor that can be safely handled by this hydraulic conveyor, while the oversize, in particular the larger solid objects or textile structures or the like described above, are fed to the collecting basket, which at intervals, e.g. can be emptied when the next shaft of the Siels is reached.
  • the collecting basket is expediently releasably connected to the chassis in the manner of a semitrailer tractor with a chassis part, that is to say can be detached from the device at suitable intervals and brought into an emptying area.
  • the hydraulic conveying device has a suction line arranged on the discharge space and a pump connected to it.
  • Discharge chamber, associated suction line and pump can be arranged on the device in a simple and robust manner.
  • the pump is expediently designed as a centrifugal pump, but eccentric screw or piston pumps can also be used. Under certain circumstances it can also be expedient to design the discharge space as a kind of collecting space and to provide a driven agitator therein as a mixing device. As a result, the promotional effect on the deposits can be increased.
  • the cleaning device can be provided with a self-tracking undercarriage running on the inner wall of the sieve, that can consist of suitable wheels or caterpillars.
  • the front part of the undercarriage in the direction of travel is expediently arranged below the guiding surface of the peeling tool in order to guide it particularly safely during its peeling work.
  • the remaining part of the undercarriage is then arranged on the rear part of the device in the flow direction, to which the collecting basket with its associated undercarriage part then adjoins.
  • the device is equipped with a chain hoist device which acts on a chain laid in the slab. This simplifies the work in the pile particularly since the chain only needs to be laid with suitable means and guided over the chain hoist device, which then drives the device to move the device with the peeling tool, both in the working direction and in Treatment direction.
  • a height adjustment device is provided on the front part in the direction of travel and is supported on the wall of the level.
  • This height adjustment device is expediently arranged below the peeling tool and serves to overcome obstacles or steps in the soleplate indicated by the device becoming stuck. If the peeling tool encounters such obstacles or steps, this is determined by suitable means, in particular by a tensile force measuring device on the chain hoist device, the device is retracted somewhat, raised to the new sole level with the height adjustment device and moved again in the feed direction after overcoming the obstacle can the Height adjustment device can be lowered again to the sole level then reached.
  • Pressure equipment-operated lifting devices are particularly suitable as the height adjustment device.
  • the device is provided with a vibration device acting on the peeling tool.
  • a vibration device acting on the peeling tool.
  • the device according to the invention it is thus possible to remove even the non-suspended deposits, which can possibly achieve considerable strength over a long period of time, from the inner wall of the sieve, the entire deposits being lifted off, and a reliable removal of these deposits with largely automatic Operation in the Siel enables.
  • the device can be put together from assemblies in a robust and easy to assemble manner.
  • These assemblies consist on the one hand of the peeling tool with its undercarriage part, the peeling tool being expediently detachable and exchangeable in order to take account of the different sieve cross sections, on the other hand of a further movable device part with the inlet sieve, the vibration device, the respective drive device, in particular the chain hoist device, and the discharge room with its suction line and the suction pump, and thirdly from the grass catcher with its associated chassis part.
  • FIGS. 1a and 2 show the basic structure of the cleaning device according to the invention.
  • this device In the flow direction 1 indicated by the arrow 1, which also corresponds to the direction of travel of the device, this device has a peeling tool 2 which has a guide surface 2 a rising opposite to the direction of travel 1.
  • This peeling tool 2 engages, as shown in FIGS. 1 and 3, the deposits 3 located on the base of the base and detaches them from the inner side of the base when the device is moved in the direction of travel 1.
  • At the apex 2b of the guide surface 2a there is an inlet for the material to be lifted, which is closed by a sieve 4.
  • the guide surface 2a essentially fills the cross section up to the apex height 2b.
  • the discharge space 5 opens into a suction line 6, which opens into a hydraulic pump 7, in particular a centrifugal pump with a drive motor 7a.
  • Extending from the discharge side of the pump 7 is a delivery hose 8, which then leads in a manner not shown to the suitable discharge lines for the suction sludge.
  • the devices described are arranged on a suitable device frame 9, the peeling tool 2 being detachably connected to this device frame 9.
  • the device frame 9 also carries a chain hoist 10, which engages with the drive and deflection rollers 11 shown, a drive chain 12 laid in the pile.
  • a chain hoist 10 which engages with the drive and deflection rollers 11 shown, a drive chain 12 laid in the pile.
  • other flexible tension members can also be used.
  • the device frame finally carries a vibration device 13, which acts in particular on the peeling tool 2 and the inlet sieve 4.
  • a self-tracking undercarriage 14 is arranged below the peeling tool 2, which is expediently provided with a height adjustment device 15, a suitable pressure-medium-operated lifting device.
  • the peeling tool 2, optionally including the inlet sieve 4 can be detachably arranged on the device frame in order to be able to use different peeling tools 2 to adapt to different shape and size of the cross-section.
  • Detachable in the manner of a semitrailer is also coupled to the rear end of the device frame 9 relative to the direction of travel 1, a collecting basket 17 for oversize, which carries its own self-tracking undercarriage 18 at the rear end.
  • Another deflecting roller 19 secures the running of the drive chain 12. The direction of the deposited sludge is indicated by the arrow 20.
  • liquid level 23 is raised by a weir or the like by means of suitable measures in the sieve before the cleaning work begins, as the liquid level 23 indicates in FIG. 3.
