Definitions

  • the invention relates to a spreading device for spreading of liquid (brine) and granular grit in Form of grit and / or road salt (granules) from a spreading plate, which granulate over a granulate slide and a baffle is fed and one intermediate containers arranged above the spreading disc, which brine is continuously fed during the spreading process and which has an overflow opening, from which brine rising in the intermediate container emerges and down via a liquid guide surface reaches the spreading disc.

  • the granulate comes from a storage container via a downpipe to the granule slide.
  • This Baffle is part of a baffle plate, which in the is essentially provided for a liquid guide surface, which brine is fed to the spreading disc, to cover. This prevents granules from directly gets to the liquid guide surface and there, in particular with lower application rates, can stick and thus a continuous flow of the granules and also the brine is prevented.
  • the baffle plate directly on the intermediate container in the area the liquid guide surface arranged.
  • the intermediate container is arranged above the spreading disc. Brine becomes continuous during the spreading process fed.
  • the intermediate container is used to feed the brine provided with an overflow opening from which in the intermediate container ascending brine when reaching the overflow opening exit.
  • the one coming out of the overflow opening Brine passes through the liquid guide surface, which formed by the outer wall of the intermediate container is on the spreading plate.
  • the spreading disc supplied granulate is thus on the spreading disc mixed with the brine and thus moistened spread on the traffic area to be sprinkled.

  • This overflow opening extends itself in the circumferential direction over a partial area of approximately 90 °. Due to this extensive expansion of the overflow opening becomes the liquid guide surface from the outer surface of the frustoconical housing of the intermediate container is formed, determines and extends accordingly about the same angular range. Because of this frustoconical shape, widened towards the spreader plate the housing wall tends to overflow the liquid to an uncontrolled run in the direction of the spreading disc.
  • the overflow edge of the overflow opening is at the known device furthermore V-shaped, so that with small amounts of brine added a right narrow brine flow along the liquid guiding surface and in the case of extremely large brine quantities, a circumferential width of the brine flow across the entire width of the liquid guide surface is effected.
  • This in turn means that with different supply quantities of brine, these also in different peripheral areas fed to the spreading plate becomes, whereby a uniform mixing of Brine and granulate for different quantities of grit and different mixing ratios are not guaranteed can be. Since the baffle directly with the Intermediate container is connected, this is also the conical Adapted shape of the intermediate container.

  • This curved design of the baffle or the impact surface becomes a non-uniform Distribution of the granules hitting the impact surface in the circumferential direction, which is particularly the case with small Amounts of spreading material to be insufficient Mixing and thus moistening of the granules with the brine fed in at the same time, since a sometimes considerable part of the granulate not in the area the impact area of the brine reaches the spreading plate.
  • the intermediate tank is used to control the flow rate via an appropriate connection pipe during of the spreading process, brine is continuously supplied, which in the container rises to the overflow edge of the overflow opening and then overflows.
  • brine is continuously supplied, which in the container rises to the overflow edge of the overflow opening and then overflows.
  • a float element which dependent on the volume flow of the brine supplied different from the supply quantity per unit of time is raised and thus the overflow opening releases differently.
  • the invention is based on the object Device for dispensing liquid and granular To design grit in such a way that regardless of the amount of liquid supplied per unit of time The granulate is fed as precisely as possible onto the spreading disc is guaranteed and thus a uniform mixing of the granulate arriving on the spreading disc Brine is guaranteed.
  • the Baffle is flat or a granule slide towards U-shaped bent or arcuate, has an open profile through which the granule slide Coming granulated grit to the spreader is targeted and that the baffle is adjustable and / or exchangeable.
