Definitions

  • I provide in an encased belt conveyor, in combination an endless belt having aY working face, spaced retaining walls upstanding from 4said working face, a casing about said belt, means for ⁇ l-th'e friction is obtained when the conveyor is used in a 'vertical position .or when its lower side is its working side, and these correspond to the worst conditions of use to be expected. ⁇ This, prevents deterioration of the material conveyed and enables a reduction in the power required for driving the conveyor.
  • the casing is provided, at any suitable locations, with material-distributing valves associated with discharging hoppers.
  • each part of the conveyor casing in which 'is disposed one of the two straight lengths of the belt, Yconsists of one or more tubular elements of rectangular or ⁇ square cross-section butted end to end and joined together, the ends of the resulting duct thus formed being each connected to a box the interior of which forms internally the semi-circular part of the casing and contains a return drum for the aforesaid belt, one of these drums being adapted to be rotated by driving means from an electric motor with a suitable speed reduction gear.
  • the end boxes of the conveyor respectively accommodate a receiving or feed hopper and a discharge hopper the direction of the outlets whereof can be varied depending on the position in which the conveyor is being used, which may be horizontal, vertical or inclined.
  • lateral guides are preferably tted in one of the two straight parts of the casing to form grooves to support the driving or driven lower part of the belt when the conveyor is horizontal or inclined.
  • the containing walls are fixed on the belt at sorne space from the edges of the belt so that said edges form slides guided in the groove formed by the aforesaid guides.
  • FIG. 1 is an elevation on a small scale of an encased belt conveyor according to the invention, part of the casing being cut away to expose the interior;
  • FIG. 2 is a cross-section on a larger scale along the line u-a of FIG. l;
  • FIG. 3 is a perspective view of part of one of the elements constituting the casing containing lthe conveyor belt, part of the element being broken away to expose the interior;
  • FIG. 4 is an exemplary diagrammatic view on a small scale of one of the various possible applications of a group of conveyors according to the invention.
  • the conveyor consists of a conveyor belt 1, having two corrugated or wavy retaining walls 2 upstanding from the working face of the belt.
  • the walls are spaced apart in parallel relationship and are disposed within two metal casings 3 to be slidable longitudinally of the latter, the casings being suitably braced apart as shown at 4, and connected together at theirends by metal boxes 5 and 5 the insides whereof form semicircular ducts extending and connecting the ends of the casings.
  • Each of the boxes 5 and 5 has mounted therein a central drum 6 and 6', respectively, for the return of the belt 1, the drum 6 being rotatably driven through the intermediary of an electric motor M with a suitable speedreduction gear.
  • Hoppers 7 and 8 respectively, for intake and discharge, are associated with the boxes 5 and 5', and their inlet and outlet mouths are suitably directed according to the use to be made of the conveyor (horizontally, vertically or in- .clined).
  • lateral guides 9 are iitted inside the casing 3 to form grooves to support the driving or driven lower part of the conveyor belt 1, in particular when the conveyor is in a horizontal or inclined position.
  • the containing walls 2 are fixed on the belt 1 at some spacing from the edges 1 of the belt so that said edges form slides ,guided in the grooves formed by guides 9 (FIG. 2).
  • the casings 3 land 3 may consist of a number of sectional lengths each having at be attach-ed to each other when butted end to end.
  • FIG. 4 which comprises Ia horizontal conveyor I, a vertical conveyor II, and a further horizontal conveyor III working in the rever-se direction, i.e. its lower length is the loperative one, it is likewis-e possible to provide on the vertical unit, raising the material, one 4or more valves with hoppers 11 enabling the material to be discharged at different levels.
  • an endless bel-t having a working fia-ce, a plurality of spaced endless sinuous retaining walls upstanding from said helt working face, a clos-ed casing housing said belt with said walls extending across the interior of said casing, means for supporting and driving said belt the length of said casing, a rst hopper opening into said casing and disposed to supply said belt, and a second hopper opening into said casing and disposed to receive conveyed material from said belt.
  • an endless belt which includes two ⁇ mutually parallel straight lengths and two return bend sections interconnecting said lengths, said belt having an external Working face and an internal face, a plurality of spaced endless sinuous retaining wall-s upstanding from said belt working face, a pair of rectilinear 'and mutually parallel casing parts containing said straight lengths and said walls, a box at each end of said casing parts connecting said casing parts, a drum mounted for rotation in each said box with said 'belt return bend sections passing around said drums, a driving motor, speed reduction means operatively connecting said motor with one of said drums, said casing having an opening disposed for supplying material to said belt, said casing having an open-ing disposed for receiving material from said belt, and means for maintaining said belt internal face in sliding contact with said casing parts.
  • Ian endless belt which includes two mutually parallel straight lengths and two return ben-d sections interconnecting said lengths, said Ibelt having an external working face and an internal face, a plurality of spaced endless retaining walls upstanding from said belt working face, said walls 'being corrugated lengthwise of said working face, a -pair of rectilinear and mutually parallel casing parts containing said belt straight lengt-hs and said walls, a box mounted at each end of said casing parts connected said casing parts, a drum mounted for rotation in each said box with said bel-t return bend sections passing around said drums, a drivin-g motor, speed reduction means operatively connecting said motor with one ⁇ of said drums, a first hopper disposed on said casing for supplying material to said belt, a second hopper disposed on said casing for receiving material from said belt, means for maintaining said internal face in
