Definitions

  • a vertical extraction apparatus particularly adapted for use in vertical furnaces having a collar of the same cross sectional design as the lower part of the furnace in which the solid material to be extracted is located and a bearer plate adapted for movement within the collar and having a shape substantially the same as the collar for moving and extracting the material to a lower level.
  • a horizontal fragmenting or sectioning mechanism Positioned within the collar and between the bearer plate and the lower end of the furnace is a horizontal fragmenting or sectioning mechanism for retaining the flow of material when said bearer plate is carrying a portion of said material to the lower part of the vertical furnace.
  • Our invention relates generally to vertical reaction or storage apparatus and, more particularly, to an extraction means which insures a continuous, homogeneous and regular progression of solid materials traveling from the top to the bottom of a reaction or storage apparatus with a vertical axis, for example, a furnace in which solid materials are converted.
  • the known extraction devices such as gates, rotary discs, horizontal belts, slides or drawers, insure satisfactory extraction of the processed material.
  • these devices lack a uniformity in rate of descent of the processed material; for example, the speed of descent at the axis and at the periphery of the device differ considerably.
  • the known devices cannot even insure the extraction of the product.
  • our invention assures both the extraction of the product and its uniform descent within the column or device, even if this product appears in compact or hard or not very friable form.
  • our invention comprises a collar or shell or the like at the base of a reaction enclosure which has the same cross sectional area as the base of said enclosure and which may be separable and displaceable from the enclosure itself.
  • a vertically displaceable bearer to which a bearer plate having a cross sectional design substantially the same as the cross sectional design of the collar is attached. This bearer is adapted for vertical descent to lower the bearer plate to a point below the lower end of the collar.
  • the sectioning devices Between the bearer plate and the lower end of the reaction enclosure are fragmenting or sectioning devices, adapted to horizontally penetrate the descending material to thereby fragment or section the column.
  • the sectioning devices retain the portion of material above them and prevent it from descending into the collar and upon the bearer plate.
  • the bearer plate and the sectioning devices are dependent and responsive to one another, that is, the sectioning devices retain the flow of material from the reaction enclosure as the bearer plate descends through the collar to dispose of the material upon it.
  • the bearer plate When the bearer plate is in the high position, that is, when it is in the collar, the fragmenting or sectioning devices are withdrawn, and the material from the reaction enclosure rests on the bearer plate. The bearer then moves downward through the collar at a speed which has been predetermined and when it reaches the bottom of the collar, the sectioning devices are brought into action. When the sectioning devices have passed through the material in the course of their descent out of the reaction enclosure, they are separated into two portions-an upper one which is carried by the sectioning devices, and a lower one which rests upon the bearer plate and which is rapidly eliminated by appropriate means. The bearer is then raised again until it comes into contact with the sectioning devices which are then retracted. The material present in the reaction enclosure again rests upon the bearer plate and the cycle begins again. The period required for the elimination of the material carried upon the bearer may be very short, and thus, may not effect the speed of descent of the material in the apparatus appreciahly.
  • FIGURE 1 is an elevation view, partly in section, showing our invention with the bearer plate in high position;
  • FIGURE 2 is the same as FIGURE 1, except that the sectioning devices have closed and the bearer plate is in the low position of the collar;
  • FIGURE 3 is a view similar to FIGURE 1 showing the bearer plate removed from the collar and tilted to remove the processed material;
  • FIGURE 4 illustrates another embodiment of our invention in which the processed material is removed from the bearer plate without tipping
  • FIGURE 5 is a view similar to FIGURE 1 showing another embodiment of our invention in which the entire collar is removed from the reaction apparatus and tilted to remove the processed material;
  • FIGURE 6 is a side elevation of the embodiment of FIGURE 5 showing the collar and its mounting
  • FIGURE 7 is a view similar to FIGURE 5 showing the collar in tilted position for removal of the processed material from the collar.
  • a furnace 16 is filled with a product 17 being processed.
  • a collar 6 that has a cross sectional design substantially the same as the cross sectional design of the lower portion of the furnace.
  • Bearer 5 is interdependent with a strong movable carriage 5a.
  • the carriage has two horizontal spindles 7 and 9 adapted for travel in fixed vertical guides 10 and 12 respectively.
  • Vertical guide 10 is closed and guide 12 is open at its side adjacent the lower end 13.
  • Carriage 5a has an arcuate guide 15 therein which spindle 8 is movable.
  • Spindle 8 is mounted within a fixed vertical guideway 11 and secured to rod 19 of ram or hydraulic cylinder 14. Vertical movement of the ramrod causes 3 spindle 8 to move within guideway 11 and laterally within guide 15.
  • sectioning device comprising layers of rods or blades 1 which are horizontally actuated by means of rams or hydraulic or pneumatic cylinders 2 through frame 3.
  • rods or blades 1 which are horizontally actuated by means of rams or hydraulic or pneumatic cylinders 2 through frame 3.
  • rams or hydraulic or pneumatic cylinders 2 For the fragmenting or seetioning device, We prefer to utilize one or more layers of drills, blades, or jumper bars, which are either crisscrossed or horizontally positioned above each other. These are directly connected to a means for insuring a continuous thrust and/or an intermittent percussive motion similar to that of the bar or blade of a piercing hammer.
  • the number of blades or bars of a layer and the number of layers are dependent upon the nature of the material being processed at the level of the blades, and particularly important in this regard is its hardness, fragility and the final grain size desired at the end of extraction. Depending upon the conditions, it is possible to use a single layer of blades. It is also possible to employ with a single layer, several blades that intersect one another.
  • the collar 6 in which the bearer plate moves may be an extension of the lower portion of the furnace with openings therein for the passage of the sectioning or fragmenting device blades. Or, it may be independent of the lower portion of the furnace, but having the same cross sectional design as the lower portion of the furnace, where the separation between the furnace and the collar providing a passageway for the sectioning device.
  • a control system (not shown) actuates ram 14 to cause the rapid ascent of spindle 8, which first returns carriage and bearer plate to the position shown in FIGURE 2 and then lifts them to the position shown in FIGURE 1.
  • the control system causes the actuation of the rams 2 causing blades 1 to be retracted.
  • the column of material supported by blades 1 drops a few centimeters onto plate 4 which immediately 4 begins its slow descent within collar 6, thus beginning a new cycle.
  • ram 14 is actuated by a pump of much greater output and decidedly more powerful than required to actuate the descent of the bearer plate within the collar.
  • the short interruption of the descent of the product followed by the sudden small drop referred to do not have any appreciable effect on the evenness or quality of the product.
  • FIGURE 4 there is illustrated another embodiment of our invention in which the bearer plate is directly af fixed to rod 19 of ram 14. In this case, it is necessary to use a means 24) for clearing the plate when the rod has been retracted.
  • FIGURES 57 we have shown an embodiment of our invention in which the collar is removable and extraction of the product is achieved by tilting the collar.
  • the bearer plate is mounted as in FIGURE 4 and the ram 14- and collar 6 are mounted on a pivotable stand 21 which in turn is mounted on a movable holder 22. After the bearer plate has reached its lowest position, the holder 22. is moved away from the furnace and stand 21 is tilted as shown in FIGURE 7 to dump the processed material onto a hopper conveyor or the like (not shown).
  • (C) means for supporting and vertically moving the bearer plate within the collar said means including a hydraulic cylinder having a rod to which a spindle is attached and a carriage means attached to the bearer plate and including an arcuate guideway in which the spindle rides whereby downward movement of the spindle after the bearer plate is below the bottom of the collar causes the bearer plate to tilt and discharge the processed materials carried by the bearer plate;
  • (E) means for moving the horizontal sectioning means out of the reaction chamber when the bearer plate is in the uppermost position in the collar adjacent the sectioning means and for moving the sectioning means into the reaction chamber when the bearer plate is at the bottom of the collar;
