Definitions

  • the invention relates to a spray system for Precipitation of dust, especially during demolition work.
  • mist nozzle device When conveying broken goods via conveyor belts and slipping creates dust and it is known (DE 39 09 008 A1) to use a mist nozzle device in which is a multi-media nozzle inside a mist nozzle dome is attached to an adapter head that it with the Media supply lines connects. This mist nozzle dome is said to Shield the nozzle against disturbing air currents.
  • the Fog nozzle dome provides some protection against Material splinters that hit the outlet nozzle could, however, such a dome could not protect against coarse chunks of material and reinforcing iron, such as they occur during demolition work.
  • the invention has for its object a Spray mist system to create dust control suitable for demolition work and with low water consumption gets along.
  • the task is based on the characteristics of the Claim 1 solved and by the further features of Subclaims designed and developed.
  • the approach in the invention assumes that the Dust is combated directly at its point of origin, if the dust clouds still occupy a small volume. This but means that the spray nozzles in the Arrange near crushing tools without the Spray nozzles can be damaged by flying fragments allowed to. In such cases, the spray nozzles are on the one hand armored, and on the other hand, their spray is sufficient long and large to make the spray nozzle sufficiently far from the to arrange the largest danger point away.
  • Demolition work is carried out with demolition machines, so that the dust formation points are in or near this Demolition machine.
  • the spray nozzles are therefore included in the demolition machine, and that to the Mixing nozzles leading water pipes and compressed air pipes are supplied by a supply unit, which in the Demolition machine is installed.
  • the supply unit is housed in a portable housing frame to to a certain extent as a slide into a suitable room in the Demolition machine to be integrated.
  • the water supply device is equipped with valves, on the one hand to ensure the regulation of the water supply and on the other hand the water pipes when the Remove water from the system to reduce the risk of freezing to meet. For the same reason, water can Water tanks are drained.
  • the main ones Components of the spray mist system are one Water supply device 1, a compressed air supply device 2 and a mixing nozzle 3.
  • the water supply device 1 contains a water tank 10, from which a water pipe 11 via a 3-way valve 12 leads to a water pump 13 which generates the pressure serves.
  • a water pressure line 14 leads via a control valve 15 to the mixing nozzle 3.
  • the soapy water from a assigned container 17 can mix into the pressurized water.
  • a heating coil 18 is provided to the Raising the temperature of the water.
  • the water tank has a filler neck 19 and a manually operated drain line 20th
  • a level indicator 21 is also provided.
  • the compressed air supply device 2 comprises a compressor 25, a pressure vessel 26, a control valve 27 and one Compressed air line 28, which leads to the mixing nozzle 3.
  • the described parts of the water supply device 1 and Compressed air supply device 2 are from a housing frame 29 enclosed, from which the pressurized water line 14 and lead the compressed air line 28.
  • An outer protective housing 30 is by two screwed together U-iron, of which the lower U-iron has a bore 31 which on the one hand the outlet of the Spray forms and on the other hand an adjustment device 32 records.
  • the mixing nozzle 3 has a mixer housing 33 and an insert body 34 by a Housing sealing device 35 inside the housing is kept sealed.
  • the insert body 34 has one Sealing collar 36 on a water supply space 37 from one Compressed air supply space 38 separates.
  • a water connection 39 leads in the room 37, and a compressed air connection 40 leads into the Compressed air space 38.
  • the insert body has one Longitudinal bore 41, which has a radial bore 42 with the Connection 40 is connected and to a nozzle body 43 with Exit opening leads.
  • the nozzle body 43 can be designed to be electrically heatable.
  • FIG. 3 shows a rear view.
  • the housing frame 29 is welded from sheet steel and section steels and has four Wheels 51 to run on rails 52 (Fig. 4) and as Slot to be accommodated. 4 is the assembly the supply unit 50 via a dashed line Frame 53 outlined. There is also a flap 54 which can be folded onto the frame 53 and then one Platform or ramp that forms during maintenance work is useful. When folded up, the ramp serves as Stone chip protection for the supply unit 50.
  • the compressor 25 (FIG. 3) is powered by a diesel engine 56 driven. Also shown is a fuel tank 57, a starter battery 58, an oil cooler 59, a water cooler 60, a compressed air cooler 61 and a water filter device 62.
  • a three-stage air filter device contains one to the Sides of the housing frame 29 arranged grid and one Filter mat 63 as the first stage, filter cartridges 64 as the second Stage and usual air filter 65, 66 of the compressor and Diesel engine as the third stage, not shown Spiral hoses the filter cartridges 64 with the air filters 65, 66 connect.
  • the compressor 25 is with a Equipped with temperature monitoring and emergency shutdown, the same applies to the drive motor. The waste heat from the compressor 25 and the diesel engine 56 via the heat exchange system 18th supplied to the spray water.
  • Fig. 4 shows a crusher 70 for crushing Rubble.
  • a chassis 71 is provided on which Superstructures are attached to a crusher or grinder 72 to record.
  • a feed hopper 73 is used to feed coarse fragments to the grinder 72, which one Has exit 74 which leads to a main conveyor belt 75. Fine material sieved in the feed hopper is transferred to a Fine material conveyor belt 76 (Fig. 5) delivered.
  • the nozzle heads 80 are arranged in rows, as at best seen in Fig. 5, and form nozzle strips.
  • the fines conveyor belt 76 also assigned such a nozzle frame.
  • the invention can also be used in other demolition machines are used, for example in demolition excavators.
  • There the nozzle heads are placed in a nozzle rack near the Demolition pliers or the shovel of the demolition excavator housed and radiate the work area of the Demolition pliers or the shovel.
  • the spray is generally near the Generations of dust and this Areas of dust formation become entirely from the spray enveloped. That is why developing dust immediately bound and cannot spread as a cloud of dust. On this way, despite low water consumption Dust development can be combated effectively.
