Definitions

  • the present invention relates to a maintenance method of material accumulators as well as an installation suitable for implement the process.
  • accumulators of materials we mean any type of building and reserve such as silos capable of containing materials to be stored and particularly materials powder.
  • One of them may receive a large amount of material and is seriously injured.
  • the object of the invention is to remedy the drawbacks of devices and methods currently in use.
  • Figure 1 is a schematic view of an accumulator in which human intervention is carried out.
  • the installation according to the invention firstly comprises at minus a handrail fixed on the walls 2 of the accumulator 1, in its upper part, so as to ensure 3 people from the top.
  • people intervention 3 can travel the periphery of accumulator 1 while progressing towards the bottom thereof.
  • the sectors of evolution of people 3 are offset around the periphery of the walls 2 by fractionation of the handrail.
  • the installation according to the invention also comprises ropes 4 as shown in Figure 1 to ensure each person 3.
  • the ropes connect, in the mode of illustrated realization, the intervention persons 3 to one winch located or attached to the top of the accumulator 1.
  • intervention persons 3 are insured from the top of the silo avoids any risk of entanglement of rope especially in people's feet.
  • the installation presents 5 pipes for feeding people intervention 3 in oxygen.
  • Breathing air is supplied through pipes 5 from one or more compressors 7a in particular electric capable of supplying outside air up to the intervention people.
  • compressors 7b may also allow material supply.
  • the reel 6 is used for the unwinding of 5 supply hoses.
  • an air reserve is provided at outside. It provides security in the sense that it provides a minimum breathable volume allowing, in the event of a problem, to evacuate people 3 without running out of oxygen.
  • the air present inside the accumulators 1 are often not very breathable, an air supply exterior will preferably be achieved through pipes 5.
  • This work can be done by means of drain.
  • the powdery materials thus released can be recovered from the bottom of the accumulator through everything current means and in particular vehicles or machines 8.
  • a safety reserve ensures the air supply until the evacuation of people.
