Definitions

  • the invention relates to a dissolving plant for granular material, in particular for soft-bodied components such as clay and / or clay-laden minerals, nodular mineral conglomerates o. ⁇ .
  • the plant has a trough with an inlet and an outlet for the good, between inlet and Outlet is conveyed through the trough.
  • a driven in rotation, equipped with wedge tools shaft is arranged in the longitudinal axis of the trough.
  • washing machine for the removal of impurities such as clay, clay, Lithuanians, soil known to adhere to lumpy mineral Abraummaterialien.
  • the washing machine has a trough and arranged therein, equipped with washing tools shaft. The trough is retracted above the shaft.
  • the washing tools have off-shaft blade portions that are radially directed toward the drawing. The laundry to come into contact with these areas should roll inward along it. The estate should be swirled. All this speaks against a wedging effect of tools with pressure build-up on the goods by wedging action.
  • the shape of the trough is basically not critical either, as the trough hogs during operation. That is, at the trough wall, a tank forms adhering Guts extending in the circumferential direction of the shaft and between the and the wedging tools remains a working gap.
  • the Beschamottieren the trough is desirable because it counteracts the wear.
  • the trough has a semi-cylindrical bottom and vertical side walls.
  • the shaft lies in the cylinder longitudinal axis.
  • bottom and walls of a trough of the dissolving plant according to the invention can be prefabricated accordingly, but this is not mandatory. Even with other trough shapes, it can be assumed that by means of shuffling, this shell inner contour of the trough usually sets.
  • the object of the invention is to provide a dissolving system of the type mentioned with improved dissolution effect.
  • the tray is narrowed at the tool ascending side above the central axis of the shaft away from the perpendicular by an insert therein upwardly and inwardly.
  • the circumferential part is extended, is built on the pressure in the upward movement of the wedging tools on the estate.
  • the trough narrowing the insert can be rigid.
  • An advantage of this variant is that the insert easily hoggles. But there is a risk of damage in a transition to coarser grain or the unexpected accumulation of coarse-grained impurities in the estate.
  • the trough narrowing insert is movable.
  • the insert can be articulated in particular to the trough.
  • the insert is resiliently buffered on the trough. This prevents that to be treated good between trough and use sets and affects the mobility of the insert.
  • the insert is spring-loaded against the trough.
  • spring is a helical compression spring made of spring steel into consideration. Has proven also a gas spring, which should preferably be adjustable in their spring characteristic.
  • the insert has an active surface which is curved in the circumferential direction of the shaft or extends tangentially or polygonal thereto.
  • the active surface runs in the direction of rotation of the shaft to the wedging tools, so that narrows the wedge gap. This is particularly recommended on the last degrees of centrifuge lengthened by the insert, over which an upward movement of wedging tools with strong wedging action occurs.
  • the active surface of the insert is structured in the manner to be treated holding manner. This promotes the shuffling of the insert and counteracts the wear.
  • the active surface may in particular be provided with parallel grooves which extend in the longitudinal direction of the shaft. Preferably, the grooves have a U-profile.
  • the insert is provided with at least one of the active surface reinforcing insert made of ceramic or hard metal.
  • the trough is provided at the constriction with identical or identical wear sets. Latter are for the introduction of force in the direction of rotation front positively supported on the trough or use.
  • a shaft 14 is arranged, which is equipped with wedge tools 16. Regarding their attachment and design can on the EP 0 712 665 A1 and DE 202 18 917.1 U1 to get expelled.
  • the dissolver systems serve to rid granular mineral material from adhering soft components. To do this, the systems usually run wet. The trough is flowed through in countercurrent with the material to be treated by water. However, the use of water for washing the Guts is not mandatory for the invention. There are special cases in which dissolution plants run better dry.
  • the trough is provided with inserts. That creates flexibility. You can work with or without use as needed.
  • the trough of the dissolver plants in operation to a thickness thick, which is indicated by the line 18. It forms on the ground and over large parts of the trough circumference a tank of material to be treated, which adheres to the trough. The mixing is desired. It counteracts the wear.
  • the invention aims to lengthen the scaling portion of the trough to be scoured in the upward direction of rotation of the wedging tools 16 seated on the shaft 14 to thereby enhance the dissolving action.
  • internals are suitable, which take the place of the non-forming from home tank, or zuschamott in part or completely in the desired manner.
  • a wedge-shaped insert 20 is rigidly attached to the vertical side wall 12 of the trough, at which the upward rotation of the shaft 14 with the wedging tools 16 takes place.
  • the base 22 of the wedge is located at the height of the shaft axis.
  • the flat inclined surface (active surface) 26 of the wedge narrows the gap between the trough wall 12 and shaft 14 above the shaft axis. The wedge fires over approximately half the length of the active surface 26, in the thickness of the tank, which forms in the bottom region of the trough.
  • Fig. 2 is in an equally rigidly mounted wedge its active surface 26 curved in extension of the trough bottom.
  • the active surface 26 chamfers over the full length, without the need for a special structuring.
  • Fig. 3 is a wedge-shaped insert 20 similar to that of Fig. 1 designed as a housing with open to the shaft chambers 28.
  • the planar partitions 30 between the chambers 28 are directed substantially radially to the shaft 14.
  • an insert 20 is pivotally mounted on the trough wall 12 at the level of the central axis of the shaft.
  • the pivot axis 32 is directed parallel to the shaft 14.
  • the surface of the insert 20 according to Fig. 4 is simply stepped polygonal, so that two flat inclined surfaces (active surfaces) 26 are formed with a substantially tangential inclination to the shaft 14.
  • an elastic pad 34 made of rubber or a rubber-like material is arranged between the insert 20 and the wall 12 of the trough.
  • the pad 34 serves for elastic buffering. It prevents that the material to be treated settles between the insert and the trough wall and impairs the joint mobility of the insert.
  • a hinged insert 20 is buffered against the trough wall 12 in addition to the resilient pad 34 with a helical compression spring mounted above it.
  • the active surface 26 of the insert 20 is curved coaxially with the shaft 14 in the circumferential direction. It has at the height of the shaft axis a distance from the trough wall 12, which corresponds approximately to the thickness of the tank, which forms below the insert 20 by Beschamott Schl.
  • U-shaped grooves 38 are provided, which enforce in operation with good.
  • Fig. 6 are in a use 20, the design of the rest of the Fig. 5 corresponds, provided in the grooves 38 inserts 40 made of ceramic or hard metal, which completely fill the grooves 38.
  • the insert 20 double polygonal stepped so that three flat inclined surfaces (active surfaces) 26 with a substantially tangential inclination to the shaft 14th be formed.
  • the inserts 20 are hinged below the shaft axis on the trough wall 12 and buffered with an elastic pad 34 and a gas spring 42 mounted above it against the trough wall 12.
  • the gas spring 42 is adjustable in its spring characteristic.
  • the oblique active surfaces 26 of the insert 20 are formed by three identical Schllustrate arrangementsn 44, which are provided with grooves 38.
  • the wear sets 44 are positively supported in the direction of rotation at the front of lugs 46 of the insert 20.
