Definitions

  • the invention relates to a filter silencer on the intake side of a compressor with a plurality of annular damping elements, each of which merges into a curved guide element on its inner circumference.
  • Such silencers are known. They are used to dampen the compression of e.g. Exhaust gas turbochargers or gas turbine systems occurring sound waves. For this purpose, they have a plurality of damping elements which are arranged in the interior of the muffler at certain distances from one another.
  • the damping elements usually consist of a supporting part and a damping part made of damping material.
  • the sucked-in air flows through a filter arranged on the circumference of the muffler into the interior of the muffler and past the damping parts to the compressor, from which sound waves emanate against the direction of flow and thus pressure peaks and depressions occur. Soundproofing is ensured by the fact that the air flowing past in the pressure peaks is pressed into the damping material and is sucked out of this material in the pressure valleys.
  • the damping part thus acts as a buffer, which to a certain extent compensates for the pressure difference between the pressure valleys and pressure peaks, thereby reducing the sound wave amplitudes.
  • a disk-ring-shaped damping element which consists of a supporting part, the damping parts arranged on both sides of the supporting part and the grid parts fastened with rivets.
  • the damping parts are clamped between the grid parts and the supporting part has a continuous middle part and recesses on both sides.
  • the disk-ring-shaped damping element as also shown in the patent specification CH 594 139, merges into a curved guide element on its inner circumference, so that the radially entering flow is deflected into the intended outflow direction and losses due to swirling are thereby avoided.
  • Damping elements (US Pat. No. 4,204,586; from which claim 1 is delimited) are known, which consist of a plurality of segments strung together in the circumferential direction.
  • the damping elements are tensioned by a tie rod, which fixes them to each other with the help of spacer sleeves and holds them in the silencer housing.
  • DE-A 2 729 513 describes a disk muffler whose annular disks are tapered in the radial direction from the outside inwards.
  • the disks are made up of segments that are held together by rails and support rods.
  • the invention tries to avoid all these disadvantages. It is therefore an object of the invention to provide a silencer of the type mentioned, which forms a stable system even with high vibrations and which is characterized by lower manufacturing costs with improved damping function compared to the known silencers. Furthermore, it is based on the additional task of designing the silencer in such a way that the filter can be easily cleaned without disassembling the filter frame.
  • a filter silencer according to the preamble of claim 1 in that the base body of the filter silencer is designed as a cast monoblock with radiating ribs, the ribs having grooves into which the damping segments can be inserted radially and are thereby fixed in the axial direction of the compressor and that a filter frame secures and braces the damping elements in the radial direction, the filter frame consisting of a removable perforated plate or a plurality of removable perforated plates connected to one another by connecting elements.
  • the perforated plate has round holes and segment clip screws or buckles are used as connecting elements.
  • each damping element on the housing wall has a smaller thickness than the other damping elements and each damping element consists of several, preferably four damping segments.
  • the damping segments are preferably disc-shaped, but can also be conical or curved. It is expedient if the inner damping elements merge into curved guide elements on their inner circumference.
  • plastic filter material is advantageously used.
  • the base body is designed as a cast monoblock. It was made by chill casting.
  • the silencer consists of a with the compressor z. B. an exhaust gas turbocharger firmly connected muffler housing 1, arranged in the interior of the housing 1; essentially disc-shaped damping elements 2 and 2a and the filter 5 arranged on the circumference of the housing 1.
  • the damping elements 2 are designed on their inner circumference as curved guide elements 4, so that eddy losses of the emerging partial flows are largely avoided.
  • the disk-shaped outer damping elements 2a located on the housing wall generally have only half the depth of the damping elements 2 in the axial direction and have no guide elements 4.
  • damping elements 2 and 2a each consist of four damping segments 3, as can be seen from FIG. 3.
  • a damping segment 3 is formed from two molded and punched perforated sheet metal halves which carry the damping material.
  • the assembly of the damping segments 3 is very simple and can be seen from FIG. 3.
  • the damping segments 3 are pushed radially into the base body and fixed by the radially arranged grooves 6.
  • a filter frame braces and secures the damping segments 3 in the radial direction. This results in less assembly effort compared to the prior art, since no riveting of the damping segments is necessary.
  • tension rods are no longer required for bracing the damper segments 3, since the base body consists of one part and the silencer as a whole is a very stable system, even with very high vibrations.
  • the necessary spacing between the damping elements 2 by spacer sleeves, which is necessary in accordance with the prior art, is also dispensed with, so that the assembly effort is reduced again.
  • Another advantage results from the design of the filter frame.
  • This is formed by a perforated plate 7 with round holes or, in another embodiment according to FIG. 4, by a plurality of perforated plate parts 7 with round holes, which are connected to one another by segment clamp screws 8.
  • the filter material can be removed by removing a grid 9 removed and easily cleaned without disassembling the filter frame.
  • the round holes in the perforated plate 7 guarantee, compared to the perforated plates with square holes previously used, an enlarged transverse passage area, which leads to a reduction in the pressure losses in the filter.
  • Plastic is used as the filter material, which is pressed against the filter frame from the outside by the grid 9.
  • the filter material often breaks apart under high vibrations. Larger parts of it can get to the compressor and damage it. This is avoided when using plastic.
