BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Fig. 1 is a schematic elevational view of one embodiment with the tube shown in cross-section with a spring arm.
Fig. 2 is a side view of a solid arm.
Fig. 3 is a side view of a brush arm. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S) [0014] A filling device 10 may be used with catalyst particulate 17 and other particulate matter. The filling device 10 generally includes a feed line 12, a swivel connector 14, and a helix-patterned filler 20. The helix-patterned filler 20 has a mounting surface 30 and a plurality of obstacles (arm like members) 40 mounted to the mounting surface 30. In mounting the plurality of obstacles 40 to the mounting surface 30, the obstacles 40 are positioned from top-to-bottom in a helix-pattern or stepped-helical pattern 42 around the mounting surface 30. [0015] The filling device 10 is lowered into a tube 16 to fill the tube 16 with catalyst or other particulate 17. The tube 16 may have various regions of disuniformity such as, for example, regions of tube weld and weld impingement 18, bends in the tube (not shown), etc.
[0016] The feed line 12 is used to lower (e.g. slow controlled descent) the helix-patterned filler 20 into the tube 16 and to raise the helix-patterned filler 20 out of the tube 16 as the tube 16 is being filled. The helix-patterned filler 20 may be lowered and raised from the tube 16 by any known means or technique. [0017] The filling device 10 preferably includes the swivel connector 14 (or any other known means for swiveling the helix-patterned filler 20). The swivel connector 14 may be connected at any desirable point along the feed line 12 and as shown is connected at the lower end. The swivel connector 14 may for example be a stainless steel swivel such as the type used on deep sea fishing lines. Stainless steel chain links 15a, 15b may be used to join the swivel connector 14 to the feed line 12, or to the feed line 12 and the helix-patterned filler 20. The swivel connector 14 allows the helix-patterned filler 20 to rotate without twisting the feed line 12 during a catalyst filling operation. [0018] The mounting surface 30 is preferably a stainless steel rod 32 and functions as a vertical axis for the helix-patterned filler 20. In one embodiment, the rod 32 may have a sixteen millimeter diameter and be four-hundred-fifty millimeters long. The diameter and the length of the rod 32 as well as its mass may be changed according to the parameters of any particular catalyst particulate or other particulate loading task. The rod 32 may be hollow or a solid bar.
[0019] Each of the plurality of obstacles 40 are mounted perpendicular (or nearly perpendicular) to the axial (vertical) direction of the rod 32. They may be mounted, for example, by drilling a hole through the rod 32, next inserting an obstacle 40 through the rod 32 until both ends 41a,b protrude radially and equidistantly from the rod 32, and then fixing the obstacle 40 to the rod 32 with a set screw (not shown). The obstacles 40 may also be attached to the rod 32 at one end only, such that each obstacle 40 does not pass through the rod 32. Generally, the mounting holes or openings in the mounting surface 30 also appear in a helix-pattern around the mounting surface 30. [0020] The plurality of obstacles 40 are positioned top to bottom in a helical pattern 42 (by way of example, a resilient stepped-helix pattern) around the rod 32. Each consecutive obstacles 40, for example obstacle 40a and obstacles 40b, are staggered from each other by a distance determined by the size/radius (and somewhat the mass and/or density) of the particulate. In other words the stagger distance (or gap) is a variable defined by the particulate, such distance being small enough to prevent catalyst or other particulate from falling through and getting caught between adjacent obstacles 40. [0021] Each obstacle 40 is preferably a coil spring made of stainless steel, is generally straight having stiffness sufficient to prevent, bias or impede particulate from falling through the obstacles 40. Hence, the stiffness is variable for each application and dependent upon the mass and/or density of the particulate. Other forms of obstacles 40, such as, for example, solid arms 40a (which may or may not be contoured) or brush arms 40b may be implemented (see Figs. 2 and 3). The lengths of the obstacles 40 mounted on a particular rod 32 are all generally equal. Such length is dependent upon the inner diameter of the tube 16. For example, depending upon the catalyst it might be desirable to have a three to four millimeter clearance between the end of each obstacle 40 and the inner diameter of the tube 16. In one embodiment the obstacles 40 are each made of stainless steel having a 0.8 millimeter diameter and a length of three millimeters.
[0022] The flight of the helical- pattern 42 is preferably at an angle of about seventy-five degrees from the horizontal (but may be any angle on inclination greater that sixty-five degrees), has about three twists and directs particulate about four-hundred-fifty degrees downwardly-around the rod 32. Using a proper stagger distance, spring stiffness and flight, the particulate does not fall through the stairs, but travels down the helical steps (obstacles 40). Moreover, upon impact with the obstacles 40, the particulate will bounce down the obstacles 40 causing the helix-patterned filler 20 to rotate. The rotation helps to fill the tubes 16 with particulate in a more uniform manner.
[0023] The stepped-helical pattern 42 around the mounting surface 30 has generally been described as a pattern moving around a cylinder at a constant angle of inclination. However, a pattern moving around a cone could be used if needed to avoid lodging within a tube, or the pattern of the obstacles 40 could be changed such that the angle of inclination is not constant throughout the helix- patterned filler 20.
[0024] More than one helix-patterned filler 20 can be connected and stacked below another helix-patterned filler 20, and each consecutively lower stack need not necessarily be of the same size.
[0025] The obstacles 40, if springs, are preferably coil springs although other resilient/pliable/flexible bumper devices could be used and/or the obstacles 40 could be positioned to form other than a downward helical stair (e.g. a switchback helical pattern [not shown] which may impart a different rotation). [0026] The particulate 17 could be a particulate other than catalyst.
[0027] A working example for embodiments of a helix-patterned filler 20 design follows:
[0028] Several different versions of a filler device 10 the same or similar to as shown in the attached drawing were tested. First, a pitch on the flight of forty- five degrees was implemented. It was determined that the angle was not steep enough which allowed the catalyst to wedge in the flights. The pitch was increased until it was determined that the large diameter catalyst would not flow through/between the obstacles 40. This was at a sixty-five degree angle. [0029] However, the normal sized catalyst continued to jam in the flight.
At seventy-five degrees, all catalyst flowed smoothly through the flight. It was also at this angle that the greatest 'spin' of the flight was determined as the catalyst passed down the filler 10 (approximately one revolution per second). By making the flight from biasable or resilient obstacles 40 (e.g. stiff spring, a pliable solid or brush) a vacuum hose can pass through the filler 10 since the obstacles 40 would give way and the rod 32 can be pushed close to the tube wall 16. There is very little obstacle 40 loss during loading due to the angle of the flight and numerous contacts through the filler device 10 (this differs from some prior systems, which have a near vertical orientation and therefore must absorb more of the energy of the catalyst) and hence, the filler device 10 slows the catalyst by the numerous contacts along the flight which forces it to spin. Since the flight is made from a pliable obstacle 40 and the swivel 14 is incorporated into the line/rope, there are no solid vertical members for the catalyst to strike.
