Definitions

  • the present invention relates to a chute. More specifically, the invention relates to a chute for feeding materials. Still more specifically, the invention relates to a chute which finds particular utility in feeding material to refuse-processing devices and refuse incinerators.
  • chutes which leads to the inlet of the processing device involved.
  • Such chutes have a funnelshaped upper portion and the refuse is introduced into this portion in large quantities, for example by being dropped from a crane or similar transport device. If the material which is introduced in this manner into the funnel-shaped upper portion of the chute consists of relatively small particles, the prior-art devices operate satisfactorily. If, however, a larger fraction is included in this material, then there exists the danger that the material will jam in the outlet of the funnel-shaped upper portion. This is particularly true if quantities of material are introduced which somewhat exceed the through-put capacity of this outlet opening, i.e., the point where the upper funnelshaped portion communicates with the remainder of the chute.
  • a further disadvantage of the prior-art constructions known to me at this time is the fact that the introduction of refuse into the funnel-shaped upper portion of the chute liberates rather considerable quantities of dust and small particulate material, and that it has heretofore been difiicult if not impossible to control this dust.
  • a more specific object of the present invention is to provide a chute of the type discussed in which jamming of material upon introduction thereof into the funnel-shaped portion of the chute is significantly reduced or even entirely eliminated.
  • An additional object of the present invention is to pro vide a chute of the type mentioned above in which liberated quantities of dust can be quickly and readily withdrawn.
  • a concomitant object of the present invention is to provide a chute such as set forth above, which is simple and economical to manufacture, and which is little more complicated than the existing prior-art chutes while providing considerably better performance.
  • a chute particularly a chute of the type used for feeding material into an incinerator
  • a pair of mutually inclined walls diverge downwardly and thus define a funnel which has a top opening through which the material is introduced and a bottom opening through which the material passes into a lower portion of the chute.
  • one of these walls extends substantially in one plane downwardly beyond the bottom opening and is throughout inclined with reference to a vertical at an angle which is steeper than the angle at which the other wall is inclined to the same vertical. This achieves that material which is introduced through the top opening and impacts on the one wall will slide along the same toward the bottom opening at a speed which is greater than the speed at which material impacting on the other wall slides along the latter.
  • FIG. 1 is a sectional elevation of a chute in accordance with the prior art.
  • FIG. 2 is a view similar to that of PKG. l, but on a larger scale, and showing a structure in accordance with the present invention.
  • the chute 1 carries at its upper end a funnelshaped portion 2 into which material is introduced in the direction of the arrows 3, 4.
  • This material falls freely and impacts on the mutually inclined walls 5, 6 which define the funnel.
  • the quantities 3, 4' of material which have impacted on the walls 5, 6 are so deflected that in the range 7, that is in the region of the lower opening of the funnel, they impact one another at considerable speed.
  • their kinetic energy is destroyed at this point and jamming occurs since neither portions 3', d has enough energy left to thrust the other downwardly through the outlet.
  • the chute itself is again designated with reference numeral 1 and the funnel-shaped upper portion of the chute is designated with reference numeral ll.
  • the walls 5, 6 are inclined in approximately the same manner as is shown in FlG. 1.
  • a movable Wall or wall section 8 is arranged within the funnel l1 overlying the wall This movable wall 8 is pivoted to the wall 6 at a pivot point 35 so as to he swiu able about this pivot point between a plurality of alternate positions of which one is shown in dashe lines and identified with reference numeral 8.
  • the movable wall 3 It is the purpose of the movable wall 3 to be so adjusted that material which impinges thereon can slide only slowly along this wall 8 and into the region of the bottom opening 7. In other words, whereas material impacting the wall 5 will slide quickly therealong because of its steep angle, the kinetic energy of articles or materials impinging on the wall 8 is substantially destroyed by the impact and they can slide off the Wall 8 only at a rate of speed which is considerably slower than in the case of wall 5.
  • the holding capacity of a funnel such as shown in FIG. 2 may be the same as that of prior art devices.
  • its over-all dimensions need not exceed those of the prior art.
  • the device in accordance with the present invention can accept greater quantities of material within a given period of time because of the more rapid passage of the material from the funnel and into the chute.
  • an excessively large quantity of material is introduced into the funnel of the novel device at one time, this does not adversely influence the operation of the device.
  • the angle of inclination of the wall 8 with respect to a vertical is preferably adjustable; however, this is by no means an indispensible prerequisite. If adjustability is in fact desired, then it is advantageous to secure an upper edge portion of the wall 8 pivotally to an upper edge portion of the wall 6 by means of a hinge or similar device so as to be swingable or pivotable thereabout, as seen in FIG. 2.
  • the change to the position 8 (and others) should be possible during operation of the device.
  • Means for carrying out such movement be they manual, mechanical or electrical, are so well known that a specific description thereof is not believed to be necessary.
  • a vibrator may be provided for vibrating the wall 8, such as the one schematically shown at 1'7.
  • the vibrator will be directly mounted on the wall 8 although other solutions are of course possible.
  • Movement of the wall 8 in the sense tending to engage the wall 6 is preferably so limited that a free space remains therebetween. Since in the embodiment shown in FIG. 2 the wall 8 is pivoted to wall 6 at the point 15, the two walls define with one another an angle so that between them there exists a free space which is downwardly open. To prevent backing-up of material into this space, a screen or grating 13 may be provided which closes off this space from the remainder of the device.
  • Dust which develops in considerable quantities during operation of the device can, however, pass through the screen or grating into the free space 17, and it is advantageous to provide one of the many well-known suction devices and to so arrange the same that it communicates with the space 1'7, for instance by means of a tube 12, so that dust rising into the space 17 can be evacuated therefrom.
  • a gate or dam-per member 14 can be provided which may be privotally secured to a wall of the chute 1.
  • Such a member 14 may either normally extend across the respective opening to be deflected out of the way by the pressure of downwardly moving material, or it may be made to be selectively movable. The means for carrying out the latter operation are again so well known that it is not believed necessary to describe them.
  • a pair of mutually inclined downwardly converging walls defining a funnel having a top opening through which material is introduced and a bottom opening through which the material passes into a lower portion of said chute, one of said walls extending substantially in one plane downwardly beyond said bottom opening and being throughout inclined with reference to a vertical at a.
