Definitions
- the boom is supported by a stationary tower, and the boom and pipe are provided with coincident pivotal and rotational joints which permit the boom and pipe assembly to be-driven in vertical and horizontal planes separately or simultaneously by drive mechanism located on the tower to control the annular and transverse dimensions of the pile.
- FIG -5 46 5 APPARATUS FOR STORING A FLUENT MATERIAL This is a division of application Ser. No. 35,180 filed May 6, 1970, now U.S. Pat. No. 3,661,283, issued May 9, 1972.
- chips remain in storage, particularly outside storage, for too great a period of time, there is a marked decrease in both the strength and brightness of the papermaking pulp made from these chips. Additionally, the chip storage will often be adjacent a pulping operation, and extended storage periods may result in contamination by fallout from the pulping operation. Therefore, if the wood chips are merely deposited on the ground, and, as is customary, spread out in a rectangularly shaped pile, it will be seen that there is little control over the sequence in which the chips are reclaimed.
- the last chips deposited in the pile may be among the first reclaimed, possibly before they have aged to the degree desired, while the first chips deposited maybe among the last reclaimed, resulting in a pulp inferior in both strength and brightness.
- first in-first out storage is to utilize a pipe connected at one end to a source of wood chips and at its other end to a wheeled supporting platform.
- a fixed boom projects rearwardly from the wheeled tower and carries the end of the pipe so that as the platform is moved in a substantially circular path, chips may be projected rearwardly therefrom to form a substantially circular or annular pile roughly coinciding with the circular path of the wheeled platform.
- a deflector may be mounted on the terminal end of the pipe for adjustment to vary the angle at which the chips .are deflected as they leave the pipe.
- the tower alone may be feet or more in height, while the overall length of the boom and its oppositely projecting counterweight may be in excess of 100 feet.
- the present invention provides a method of and apparatus for storing wood chips in an annular pile. This is accomplished by use of a fixed supporting tower upon which is mounted an outwardly extending boom carrying one end of a wood chip conveying pipe.
- the boom is provided at its tower end with joint structure which permits it to be rotated in a substantially horizontally plane and pivoted in a substantially vertical plane, simultaneously if desired, and the pipe carried by the boom is provided with corresponding joints having axes coincident with the pivotal and rotational axes of the boom.
- the boom is merely rotated on a vertical axis as chips are projected from the terminal end of the pipe carried by the boom, so that a substantially annularly shaped pile can be formed.
- the boom and pipe are movable in a vertical plane, the distance between the terminal end of the pipe and the upper surface of the pile may be kept at a minimum, thereby minimizing the travel path of fine wood particles while they are subject to the prevailing winds, and correspondingly minimizing air and water pollution.
- the transverse dimension of the pile may be controlled with little or no use of deflectors or storing vehicles, thus reducing chip damage.
- a further advantage of a vertically movable boom is that the boom and pipe may be lowered to facilitate maintenance and, at times of high winds, to decrease wind loads.
- a further feature of the present invention is a unique joint construction and a drive mechanism which provide the low speed, high torque drive necessary for both proper control of the chip pile dimensions and resistance to the rather significant wind loads encountered in a structure of this type.
- the present invention provides a method of and apparatus for storing chips in an annularly shaped pile without the necessity of elaborate movable supporting structures, specially designed tracks and movable pipe supports, and decreases the need for deflectors for con trolling chip pile configuration.
- FIG. 1 is an elevational view of apparatus according to the present invention showing a portion of an annular pile of material being deposited about the structure;
- FIG. 2 is a plan view of material deposited in an annular pile
- FIG. 3 is a somewhat schematic perspective view of the cable threading arrangement of the boom drive mechansim
- FIG. 4 is an elevational view of a portion of the boom and supporting structure
- FIG. 5 is a cross sectional view taken on line 5-5 of FIG. 4;
- FIG. 6 is a cross sectional view taken on line 6-6 of FIG. 5;
- FIG. 7 is a partial cross sectional view of the drive mechanism for rotating the boom in a substantially horizontal plane
- FIG. 8 is a side view thereof
- FIG. 9 is an elevational view of the pipe pivot connection with portions of the supporting structure shown in phantom.
- FIG. 10 is an exploded perspective view of the pipe pivot and rotational joints.
- FIG. 1 shows chip handling apparatus including a stationary support structure 10 carrying a boom 11 which in turn supports a pipe 12 terminating in a deflector 13.
- a counterweight 14 is also mounted on the support structure and extends outwardly therefrom opposite the boom 11.
- a hopper l5 feeds into a reclaim pit 16 having means, in-
- the pipe 12 is in communication with feeding apparatus 20 including a hopper 21, a belt conveyor or the like 22 and a centrifugal blower 23.
- the material to be piled is conveyed by means of the feeding equipment 20 and pipe 12 to the support structure 10, which is centrally located with respect to the pile to be formed, and the material is projected through the pipe 12 in a direction away from this central point along a line extending substantially radially therefrom.
- the boom 11 is slowly rotated about its connection to the tower l0 and thereby rotates the line of projection about a central vertical axis 25 to form a substantially annularly shaped pile of the material.
- the boom in addition to being rotatable about the axis 25, as indicated by the arrows 30, the boom can be pivoted in vertical planes as indicated by the arrow 32 in FIG. 1.
- This not only permits the terminal end of the pipe to be positioned fairly close to the pile of material and thereby to eliminate the problem of wind separation of fines, but it also allows the trajectory of the material being projected from the pipe to be varied and thereby to increase the transverse width of the annularly shaped pile.
- an annular pile is formed having sloping sides 33, lying more or less at the angle of repose of the material being piled, and a substantially horizontal upper surface 34.
- material may also be re claimed concurrently in substantially the same sequence it is deposited by removing the material from the pile along the face 35 thereof extending substantially radially outwardly from the above noted central point, and delivering the reclaimed material to the hopper 15 and reclaim pit 16, whence it is conveyed by the conveyor 17 to some area remote from the reclaim pit.
- two piles as at 31 and 31, may be formed.
- the boom and pipe are rotated to the terminal face of the pile of that species and that pile is extended until chips of the other species are received.
- the deposition process is then terminated and the boom and pipe rotated to the face of the pile of the other species so that it may be extended. While two species piles are mentioned by way of example, it will be apparent that any number of species may be stored in a similar manner.
- the boom 11 includes an outwardly extending upper strut 40 and a pair of outwardly extending lower struts 41 interconnected by suitable bracing structure, as at 42.
- Each of the lower struts 41 is affixed at its inner end by welding or the like to a gusset plate 43, which in turn is pivotally attached by means of the pin 44 to the upstanding bracket 45 having outwardly extending strengthening ribs 46 (see also FIG. 5).
- Both of the brackets 45 are attached to inwardly extending channel members 47 which in turn are attached adjacent their inner ends to the reinforcing structure formed by channel members 48 and comer braces 49.
- a mast 50 including a pair of substantially vertically and inwardly extending rear mast members 51 and a pair of upwardly, rearwardly and inwardly extending forward mast members 52, with all four mast members joined together adjacent the jacking device 54.
- jacking device 54 includes a rotatable internally threaded member positioned therein in engagement with a threaded shaft 55 which is pivoted, as at 56, to the upper boom strut 40.
- Also mounted on the support structure but extending rearwardly therefrom opposite the boom 11 are a pair of lower strut members 57 and an upper strut member 58 interconnected by suitable cross bracing and supporting the counterweight 14.
- the support structure 10 is formed with up-.
- wardly and inwardly inclined legs 60 which are joined at their upper ends to a platform structure 61.
- a platform structure 61 Mounted on the upper surface of the platform 61 is a substantial cylindrical wall 62 having a series of reinforcing gussets 63 extending between the wall 62 and the upper surface of the platform 61.
- the channel members 48 and 49 as seen in FIGS. 5 and 6, have affixed to their lower flanges by welding or the like a substantially annularly shaped member 64, undercut at its periphery to form a shoulder 65.
- a ring 66 is attached to the lower surface of member 64 with its outer surface flush with the undercut portion of member 64, and a second annular plate 67 is attachedto the lower surface of ring 66 to form a pulley 68.
- a third annular plate 70 is affixed to the upper ends of wall 62 and gussets 63 and has attached to its upper surface by means of bolts or the like 71 a bearing race 72 which cooperates with opposed bearing race 73 attached to the lower surface of member 64 by means of bolts or the like 74 to confine a plurality of bearings 75 therebetween.
- one or more fittings 76 and bores 77 will be provided in race 72 for lubricating the bearing.
- a pulley actuating device 80 is also mounted on the upper surface of the platform 61.
- the actuating device 80 includes a jack screw 81 driven through suitable gearing 82 by a motor 83.
- the jack screw is rotatably mounted, as at 84, and intermediate its ends carries an internally threaded cross bar 85 which threadedly receives the jack screw 81 and has rotatably mounted thereon inner and outer sheaves 86 and 87.
- pairs of upper and lower sheaves 88 and 89 Positioned adjacent each end of the jack screw 81 are pairs of upper and lower sheaves 88 and 89, respectively, while a pair of cable members 90 annd 91 are trained about the pulley 68 and the inner and outer and upper and lower sheaves in the manner described below.
- the first cable 90 shown in solid lines, is attached to a channel member 48 at 92 and trained about the pulley 68 in a clockwise direction. From pulley 68 the cable 90 is trained to and around the left-hand upper pulley 88, thence to and around the outer sheave 87, again in a clockwise direction as seen in FIG. 3, thence to and around the lefthand lower sheave 89, thence to the right as seen in FIG. 3 and around the inner sheave in a counterclockwise direction, and thence to a point of attachment 93 on the platform 61.
- the cable 91 shown in phantom lines in FIG. 3, is attached as at 94 to a channel 48 and from this point is trained in a counterclockwise direction about the pulley 68, thence to and around the upper right-hand sheave88 in a clockwise direction, thence to and around the outer sheave 87 in a counterclockwise direction, thence to the right and around the lower right-hand sheave 89 in a counterclockwise direction, thence to the left and around the inner sheave 86 in a counterclockwise direction and thence to the right to "a point of attachment 95 on the platform 61.
- the boom structure carries the pipe 12, which may be attached thereto at a plurality of points, as at 100, FIG. 1 of the drawings.
- the pipe 12 must similarly be provided with joints for pivotal and rotational movement.
- lower section 102 is provided with an outwardly projecting flange 102' attached by means of bolts or the like to a flange 103 on an inner tubular member 104.
- Member 104 is in turn telescopically received in an outer tubular member 105 bolted through its flange 106 to a flange 107 on the lower end of a pipe pivot joint, referenced in its entirety by the numeral 108.
- Packing may be carried by the outer tubular member 105 in engagement with the outer-surface of the inner tubular member 104 to provide a sliding seal therewith.
