Definitions

  • the invention is directed to a device for generating conveying air for blowable media to be transported from silos, in particular the invention is directed to a conveying air compressor which can be carried on silo vehicles.
  • Silo vehicles that transport inflatable media such as sand, flour, lignite dust, plastic granules or the like. are usually equipped with compressors that generate the air flow necessary to convey these substances. Motor-driven rotary lobe blowers are often used.
  • the object of the invention is therefore to provide a solution with which sustainable noise reduction can be achieved when operating such air compressors.
  • the invention therefore provides that at least one ventila between the electric motor and the compressor torrad is provided, the air intake opening being arranged upstream of the cooling fins of the electric motor in the flow direction of the air drawn in by the fan wheel and the compressor intake port being arranged downstream.
  • the sucked-in air is first used to cool the electric motor before it is sucked in by the compressor, i.e.
  • the housing is always flushed with a large amount of cooling air during operation, which can then be sucked in directly by the compressor as working air.
  • the silo vehicles do not necessarily have to be equipped with conveying air compressors; here it is often sufficient if they are available to the end user, for example when large quantities of plastic granules are delivered for further processing.
  • the invention sees in A further embodiment provides that the entire unit is accommodated on a chassis, so that it can be moved by one person, for example from the storage silo to the storage silo, if appropriate silo vehicles deliver materials. Full sound insulation is also guaranteed in this case.
  • the device generally designated 1 has, in an approximately cross-sectionally U-shaped housing 2 according to FIG. 2, an electric motor 3, a fan wheel 4, a clutch 5 and a compressor 6 in a uniaxial construction from left to right.
  • the intake manifold of the compressor is designated 7, the compressed air discharge line 8.
  • the common housing 2 is additionally housed in a soundproofed capsule 9, which is only indicated in FIG. 2 and is completely missing in FIG. 1.
  • An air intake opening 10 is provided in the bottom left of the housing in FIG. 2, in which a grille, designated 11, is used to keep dirt out.
  • the fan wheel 4 sucks in air through the opening 10 or the grille 11, which is indicated by an arrow 12.
  • the ventilation wheel 4 then leads this air past the cooling fins 13 of the electric motor 3 to the intake manifold 7 of the compressor, this air movement is indicated by the arrow 14 in FIG. 2.
  • the compressor 6 is also cooled at the same time.
  • the sucked-in air serves as conveying air and is compressed for further use by the air supply line 8.
  • suction opening 10 can be equipped with additional baffles that prevent the emission of sound, and the like.
