Definitions

  • ABSTRACT A bulk transporter comprises a pressure-retentive container adapted to be displaced along the ground and provided with a pair of downwardly converging discharge cones.
  • Each cone in turn is provided with an internal arch-breaker and has a fluidized internal wall to prevent the bulk from becoming compacted.
  • the arch-breaker element is rotated around the inside of the cone, adjacent the gas-fluidized wall.
  • This element can be an auger which also serves to pull the bulk toward the outlet mouth of the cone whence it is pneumatically blown away through an unloading conduit.
  • a bulk-goods transporter generally comprises a cylindrical container fitted with wheels to act as a trailer and having at least one downwardly directed discharge cone.
  • the bulk is unloaded by simply opening the bottom outlet of the cone and allowing the material to flow out, often under the effects of air pressure applied above the goods.
  • Another object is to provide such a transporter which overcomes the above-mentioned disadvantages.
  • a transporter comprising a pressure-retentive container substantially as described in my US. Pat. No. 3,4l9,3 provided with means, such as wheels, supporting it and having at least one downwardly converging discharge cone.
  • This cone is'provided with gas-fluidizing means for preventing the flowable material from packing near the wall, and an arch-breaker element which can sweep this wall.
  • the arch-breaker element ofthe invention sweeps along a generally downwardly convergent frustoconical wall of the discharge cone, preferably over the entire axial length thereof (ie from the wide mount at the upper end of the cone to the narrow outlet at the bottom thereof), while a fluidizing or aerating (loosening) gas is introduced along this wall.
  • the archbreaker element is generally elongated and lies along a generatrix of the cone and has formations closely spaced front this wall.
  • the arch breaker element serves to interrupt the aerated layer and creates pulses therefrom which have a more significant loosening effect than a continuous air flow. Between pulses of air, moreover, there are intervening pauses as the arch-breaker element sweeps along the wall, therefore preventing the aerated or fluidizing air from packing any arch of the flowable material from below.
  • the aerating gas also cooperates to keep the arch-breaker element from packing the bulk material along the wall of the discharge cone and serves to sweep any accumulation of the bulk material from the arch-breaker element as the latter breaks up such material.
  • the present invention is applicable, as previously noted, to
  • the archbreaker element includes a rod, shaft or bar lying along a generatrix of the discharge-cone wall and coupled at its lower end by an elbow or knuckle with a drive shaft lying along the axis of the discharge cone.
  • the shaft, rod or bar is provided with spaced formations therealong of a configuration and orientation such as to direct the bulk material downwardly toward the outlet and the apex of the cone.
  • the formations may be worm, ribs, vanes, or blades in accordance with the particular requirements.
  • the rod or shaft may be rotated about the cone axis, i.e.
  • the aerating means can be provided in any of a number of configurations, eg as a sintered-metal dischargecone wall through which the fluidizing gas is forced, a perforated wall, or a wall provided with spaced apart opening preferably located at least in the region of a horizontal plane through this cone approximately midway between the large diameter mouth and the outlet.
  • FIG. I is a side elevational view of a bulk-goods transporter according to the present invention.
  • FIG. 2 is a vertical section, in enlarged scale through a detail of FIG. 1;
  • FIG. 2A is a detail of FIG. 2, in enlarged scale
  • FIG. 3 is a section according to line III III OF FIG. 2;
  • FIGS. 4 and 4A, and FIGS. 5 and 5A are views similar to FIGS. 2 and ZA showing two further embodiments of the present invention.
  • a bulk transporter consists of a pressurizable container I having a pair of filling ports 3 and 4 fitted with respective gastight caps 5 and 6 and a pair of discharge cones 7 and 8 fitted with respective unloading devices 9 and I0. 7
  • a supply I8 of compressed air can be connected to the interior of the container I at 17 to pressurize it, and to drive the flowable bulk goods out through the conical outlets 7 and 8.
  • FIGS. 2 3 show the unloading device 9, which is identical to the device I0. It has a conical inner wall 20 made of porous sintered metal, although polyester fabric or the like is usable, and a gastight outer wall 21 together defining a conical annular chamber 22 which is connected through a conduit 23 to a source 11 of compressed air. These walls 21 and 22 end at their lower edges at an outlet 24 which is formed with a laterally extending outlet conduit 25 and fitted with a hydraulic motor 26 connected via a conduit 27 to a source of hydraulic fluid 12.
  • This motor 26 has a drive shaft 28 which lies on a vertical axis 29 and is attached at its upper end by a universal joint 39 to an auger 30 which is rotated to pull bulk material toward the apex of the cone, toward the outlet 24 (see arrow 34).
  • Thefree end of the auger 30 is provided with a roller 31 that runs around the upper inside edge of the wall 20 in the direction shown by arrow 32 as the rotary motion of the motor about axis 29 is translated into rotation of the auger 30 about its longitudinal axis 33 which pulls the bulk material toward the outlet 24 and sweeping of the auger along the wall 20.
  • a conduit 38 attachable to a compressed-air source 19 and formed with a nozzle 35 having two tips 36 and 37.
  • FIGS. 4 and 4A show an unloading device 9 wherein a motor shaft 43 is rigidly connected (without a universal joint) to a pair of sweeping elements 41 and 42 in the form of bars provided with upwardly and downwardly extending spikes 44 and fitted at their ends with sliders 45 and 46 adapted to slide around the upper periphery 48 of the device.
  • this embodiment is identical to that of FIGS. 1 3.
  • FIGS. and 5A show a device 9" having a motor shaft 63 is rigidly connected to a shaft bar 55 which extends along the inside of a single-walled cone 56 and is fitted at its upper end with a slider 60.
  • This rod 55 is fitted with three small shovels which are inclined backwardly downwardly relative to their orbits as shown by the arrow 61 so that they urge the product flowable goods downwardly as they sweep the wall 56.
  • the source 11 feeds compressed air through a conduit 58 to a ring 59 surrounding the device 9" whence it passes through a plurality of connections 59 into the cone 56.
  • a bulk-goods transporter comprising:
  • At least one arch-breaker element including a shaft lying along and substantially parallel to said wall in said cone bet-ween said mouth and said outlet;
  • said gasfluidizing means includes a porous inner wall of said discharge cone and a nonporous outer wall, defining an annular chamber around said cone, and means for pressurizing said chamber for forcing gas under pressure through said porous wall.
