Definitions

  • the invention relates to a slag crusher with a pressure housing, one by the Rotatable shaft passed through the pressure housing with several, spaced thereon attached, rotating cutting blades that are angularly offset on the shaft are arranged, and with several, arranged side by side under the shaft fixed cutting knives, each rotating cutting knife in Crusher area between two adjacent fixed cutting knives is passed through.
  • the slag crusher can be at the outlet of a radiation cooler or gasification reactor with a quench section with an underwater Pressure housing may be arranged.
  • Such a slag crusher is known from WO-A-86/05198.
  • the rotating shaft is here on the vertical center line of the pressure housing, i.e. centrally arranged.
  • a slag crusher developed by the applicant was dammed up uncrushed and too large chunks of slag above the rotating knives and were always due to the too small opening between the baffles on both sides pushed up again and not fed to the knives.
  • the object of the invention is therefore to arrange the cutting tools in such a way that both small and large pieces of slag are completely covered and one controlled crushing and removal of the slag from the slag crusher.
  • the fixed cutting knives have a long and a short leg.
  • the fixed cutting knife on the side of the long leg is one in one Straight merging circular arc and on the side of the short Leg only an arcuate recess, based on the vertical Center axis of the pressure vessel introduced.
  • the fixed cutting knives are releasably attached to consoles within the pressure vessel; the dimensioning of the long and short leg is from the position of the fixed knife to the outer wall of the Pressure vessel dependent, the length of each fixed knife of the Arrangement to the central axis and to the arrangement opposite the round wall of the Pressure vessel is dependent in the cutting position within the pressure vessel.
  • Both the cutting and the fixed knives are large in the cutting area Exposed to wear.
  • the drive shaft passes through the pressure vessel are replaced by special glands with a lubricating or flushing system sealed.
  • the storage and drive the drive shaft is outside the pressure vessel arranged.
  • the led through the pressure housing Wave is at a distance "a" to the vertical and to the horizontal central axis.
  • the invention is based on an embodiment explained in more detail.
  • the Slag crusher from the pressure vessel (1) of the drive shaft (2), stuffing boxes on both sides (3), on the Shaft-mounted rotating knives (4) and the fixed knives (7) below and between the Inlet guide plates (12, 12a) and the guide plates of the Inlet funnels (12, 15) are arranged.
  • the crushed material is fed over the guide plates of the feed funnel (12, 15) fed to the crushing area.
  • the drive shaft (2) is eccentric or off-center at a distance "a" from the vertical central axis (20) of the slag crusher arranged so that the crushing area is in the middle of the slag crusher concentrated. This will create a uniform loading of the attachment (5) rotating knife (4) and a central one Discharge of crushed material reached
  • the rotating cutting knives (4) are halved Execution by means of fastening screws (5) and feather key (6) non-rotatable with the drive shaft (2) connected.
  • the crushing shoulders for the rotating ones Cutting knife (4) for crushing the material to be crushed form the protruding through the inlet plate (12) fixed cutting knife (7) in the crushing area with a wear-resistant build-up weld (11) are provided. They are each individually on mounting brackets (8, 10) with fastening screws (9) appropriate.
  • the rotating cutting knives (4) are known Arranged angularly offset on the shaft circumference (2), whereby it is achieved that only during the breaking process one rotating knife (4) and two fixed knives Knives (7) as a crushing shoulder or pairs of knives (7) are engaged and the other knives (4) only subsequently used.
  • the Motors is the refractive power of just one rotating cutting knife (4).
  • An essential feature of the device according to the invention is given by the fact that all internal Cutting parts (4, 7) exposed to wear are quickly interchangeable if necessary.
  • the crushed material is crushed over the cone (18) and Outlet connection (19) from the slag crusher removed and sent to a landfill.
  • Fig. 3 shows a horizontal section C - D through the Slag crusher in the cutting plane of the drive shaft (2).
  • the drive shaft (2) is in two lateral Supported (1a) in roller bearings (3a) and with Sealing elements (3) against escaping pressurized water secured.
  • the shaft (2) with the rotating cutting blades (4) is eccentric within the pressure housing (1) or eccentric at distance "a" to the horizontal central axis (21) of the pressure vessel (1) arranged.
  • the fixed cutting blades (7) are in slots the inlet guide plates (12) are arranged, these are on Brackets (8) and (13) attached. In the field of Seals (3) are close to the housing wall (1) by 90 ° offset inlet guide plates (15) arranged.
  • the inlet guide plates (12) and (15) form the so-called Inlet or material hopper for the cutting knife (4, 7).
  • Fig. 4 shows a side view E of a fixed Cutting knife (7) with a long (7a) and short Leg (7b) on the first-mentioned side (7a) an arc-shaped transition into a straight line (7c) Recess (7d) and on the latter side (7b) only an arcuate recess (7d), based on the vertical central axis (22) of the shaft (2).
  • Fig. 5 shows a view E of the fixed cutting knife (7) with a long (7a) and short leg (7b), based on the horizontal central axis (21) of the Shaft (2). On both sides of the fixed cutting knife (7) guide strips (23, 24) are attached.
