Definitions

  • the invention relates to a method and an apparatus for Fire prevention according to the preamble of claim 1 or of claim 4.
  • sparks can cause fires and explosions come.
  • the flying of sparks is usually used by a Processing machine or due to material contamination generated. Production downtimes, high property damage or even danger of human lives are the result.
  • the invention is based on the object, method and device of the type mentioned at the outset, that in a simple and inexpensive manner, safe fire prevention can be guaranteed.
  • An essential idea of the present invention lies in the fact that there is continuous funding a point is interrupted so that the flow in Individual quantities are divided, which in turn is fire-safe promoted separately. After that, the Funding is continuous again. Because of this Unraveling is now possible, even with little effort, such as it brings a quick-closing slide with it, the promotion to stop by simply holding the single amount becomes. This can be done particularly easily using a rotary valve happen as it is known per se.
  • the gas becomes pneumatic, ie by means of gas (especially air) preferably before dividing the bulk material into individual quantities separated from the bulk material, for example by means of a cyclone happens.
  • gas especially air
  • the preferred rotary valve is as usual equipped with a drive motor that controls the conveying speed the cellular wheel sluice is determined. Usually passes a period of about 0.5 to 1 s from the inlet of one Quantity of product in a cell until it continues to rotate until the product can exit the cell. In in most cases it will therefore suffice to add the cell drive Detect a spark to safely shut off to reach.
  • a brake is preferably provided, as it is known in principle for geared motors anyway. Such brakes work so that when the motor is energized the brake opens and when the power is turned off, the brake closes automatically (e.g. by spring force) and the drive fixes, which then a particularly quick stopping the Cellular wheel movement is ensured.
  • a spark detector 10 which the Heat radiation monitored in the pipeline 1.
  • a spark detector 10 As soon as an abnormally hot zone that represents a possible source of fire, flows past the spark detector (in the arrangement according to Fig. 1 "falls by"), a corresponding signal via a Signal line 11 transmitted to a central controller 12. The latter then not only inputs a warning device 13 Warning signal, but provides the power supply to a motor 14 from which drives a rotary valve 15. Furthermore, a Brake 16 engaged, which thus the rotation of the electric motor 14 accelerates breaks.
  • the source of the fire can start be deleted and / or removed.
  • To delete is with the 1 arrangement shown under pressure Extinguishing agent (water) storage 17 provided via a valve 18 is connected to spray devices 19, 19 'which in the pipe section 1 in which the source of the fire is located, and, if appropriate, in one, the pipeline section 1 Inject the extinguishing agent into the facing cell of the rotary valve 15.
  • the overall arrangement is designed such that the cellular wheel sluice 15 and between the spark detector 10 and the Pipe wheel lock lying pipe section can be easily cleared can to the product contaminated with extinguishing agent remove.
  • the pipe section between the spark detector 10 and the rotary valve 15 together Content can be removed from the entire pipeline.
  • the rotary valve 15 accordingly these requirements Easy removability of contaminated Cell contents
  • a bypass arrangement is provided in broken lines, which in turn has a spark detector 10 ', extinguishing nozzles 19' ', 19 '' 'and a rotary valve 15' includes, so that after detection a source of fire by the spark detector 10 and stopping the rotary valve 15 the product flow on the bypass arrangement can be redirected while using extinguishing agent contaminated product removed. This means less downtime ensured.
  • FIG. 2 differs differs from that of FIG. 1 in that in the pipeline 1 subsidized product pneumatic and not outdoors Case (as in the arrangement of FIG. 1) is transported.
  • a cyclone 20 is provided which separates the gas from the solid.
  • the separated gas runs through a further pipeline 21 to one Filter 22, which separates any entrained dusts.
  • a slide 22 is provided, which is also controlled by the controller 12, namely on a spark detection signal from the spark detector 10 such as this has already been explained above.
  • the slider 22 provided in the arrangement according to FIG. 2 must Now don't be too fast, because the distance, which one possible source of fire (sparks) covered by the cyclone 20 is extended considerably. This means (similar to the rotary valve 15) has a longer reaction time or a slower operation of the slide 22 permitted without the operational safety to endanger. Also in the arrangement according to Fig. 2, however, the solids flow through the rotary valve 15 interrupted.
  • Fig. 1 The variants shown in Fig. 1 are of course in the arrangement 2 also applicable. In particular, this would be the reasonably easy access to the inside of the cyclone 20 (or its content), the provision of extinguishing devices (not shown separately in Fig. 2) or the interchangeability of pipe sections or cells in the rotary valve 15.
