Definitions

  • the invention relates to a side channel blower with an impeller rotatably mounted in its housing according to the preamble of claim 1.
  • Such a side channel compressor is known from DE-PS 27 13 091. It has been shown that when gases laden with dust are conveyed, dust can be deposited in the gap between the base of the blade ring and the part of the housing which engages under it. The dust deposits can become so strong, especially when it is sticky or moisture-laden dust, that the gap is completely blocked by the dust. This leads to high frictional forces, which under certain circumstances can become so large that they block the impeller or prevent a restart after a break in operation.
  • the invention has for its object to develop a side channel compressor according to the preamble of claim 1 so that blocking of the impeller is prevented by deposited dust.
  • the scraper is arranged in the circumferential direction of the housing in the region between the center of the housing relating to the inlet and outlet opening and the inlet opening. In this area there is still a relatively low pressure in the side channel, so that the loss flow resulting from the high pressure side is already sufficiently strong to be able to transport the loosened dust out of the gap into the side channel. It is particularly advantageous that the scraper is arranged closer to the inlet opening.
  • FIG. 1 denotes a side channel compressor, the housing of which consists of two interconnected housing halves 2 and 3.
  • An impeller 4 is rotatably mounted in the housing and connected to a shaft 5 driven by a motor (not shown in the drawing).
  • the impeller 4 consists of a disk-shaped hub part 6 and a blade ring 7 arranged on its outer circumference.
  • the blade ring 7 has a greater width than the hub part 6, so that it projects beyond it on both sides in the direction of the axis of rotation of the impeller 4.
  • the two housing halves 2 and 3 are designed such that they overlap the laterally projecting sections of the blade ring 7.
  • the dimensions of the housing halves 2 and 3 are made in relation to the impeller 4 so that there is a radial gap 10 between the projecting section 8 and the lower part 9 of the housing halves 2 and 3 and an axial gap 13 with respect to the hub part 6. This ensures contactless rotation of the impeller 4 relative to the housing halves 2 and 3.
  • Wipers 11 are used on the outer circumference of the lower part 9 of the housing halves 2 and 3, which protrude in the radial direction beyond the outer circumferential contour of the lower part 9 of the respective housing half 2 or 3.
  • the wipers 11 are dimensioned in their radial dimensions such that a radial remaining gap 12 remains between them and the projecting section 8 of the blade ring 7.
  • wipers in the axial gap 13 if dust deposits should occur there. These wipers would then extend in the radial direction on the respective housing half 2 or 3.
  • Side channel compressors in which the blade ring 7 and the hub part 6 have the same width, only have an axial gap between the housing halves and the impeller. With such side channel compressors, only strippers extending in the radial direction can then be arranged on the respective housing half.
  • the arrangement of a scraper 11 on the circumference of the respective housing halves 2 and 3 is sufficient. It is useful to arrange the scraper 11 in the area towards the inlet opening of the side channel compressor, since there is a higher loss flow due to the higher pressure gradient to the side channel in the gap, which ensures that the loosened dust is removed from the gap.
