[5 7] ABSTRACT A rotary distributor apparatus with inclined conduits, stream dividers and multiple discharge ports and method are provided for uniformly distributing particulate material in a vessel for subsequent processing.
8 Claims, 4 Drawing Figures Llllllllllllllllllll' ROTARY DISTRIBUTOR MEANS AND METHOD The process and apparatus of this invention relates to handling particulate materials and particularly to uniform distribution within a vessel by amount and particle size for subsequent processing, such as aqueous acid leaching of mineral values from ore particles.
In various fields of art such as sludge processing, silage storage and ore processing there are numerous means for handling particulate. Typical means are described in U.S. Pat. Nos. 797,073; 805,128; 833,704; 2,940,573; 3,064,833 and 3,446,372. These means are complicated and inadequate for handling particulate material for subsequent processing.
The method and apparatus of this invention provide a simple inexpensive system for handling particulate material. The material can be uniformly distributedin a vessel with by amount and by particle size radially from an axis of rotation at each level in the vessel. This uniform distribution make subsequent processing more efficient and effective than with previous distribution methods.
By this invention there is provided a distributor means for uniformly distributing particulate material into a vessel so that the material has a substantially uniform particle size distribution at each level in the vessel radially from a vertical axis of rotation of said distributor means, said distributor means comprising a bearing means for rotably supporting a distributing conduit means; a drive means for rotating said distributing means; a receiving means connected to and communicating with said distributing means to transfer said particulate material from a separate source to said distributing conduit means at a controlled proportionate rate; and said distributing conduit means comprising at least one conduit inclined downwardly from the inlet end at the connection with the receiving means, at least one of said conduits having at least two ports at different distances from said inlet end, each of said ports except a terminal end port having at least one divider to divide a stream of particulate material passing downwardly through said conduit into a predetermined number of portions with each portion being a predetermined portion of the stream and each portion having approximately the same particle size distribution as each other portion.
The method ofthis invention embodies the principles of a preferred apparatus of this invention; it provides a process for uniformly distributing a particulate material into a vessel so that the material has a substantially uniform particle size distribution at each level in the vessel radially from a vertical axis of rotation of a rotary distributor means said distributor means comprising a receiving means connected to and communicating with a distributing conduit means, a bearing means, a drive means, divider means and discharge ports; said process comprising transferring said particulate material from a separate source into the receiving means of said distributor means, said distributor means being rotatably supported by said bearing means; rotating said distributor means by said drive means; transferring a stream of said particulate material from said receiving means to distributing conduit means at a controlled proportionate rate, said distributing conduit means having at least one conduit inclined downwardly from the inlet end at the connection with the receiving, at least one of said distributing conduit means having at least two discharge ports at different distances from said inlet end, each of said ports excepta terminal end port having at least one divider, said distributor means having a divider at the inlet of the distributing conduit means; dividing the particulate stream at the inlet of the distributing conduit means into a number of portions with the portions corresponding to the conduits and each portion having substantially the same particle size distribution as each other portion; transferring each portion downwardly along each respective conduit; dividing each portion along the conduit into portions corresponding to the discharge ports along the conduit and discharging each portion from the corresponding port into the vessel at the preselected distance from said vertical axis.

FIG. 2 is a plan view of a two conduit rotary distributor.
FIG. 3 is a plan view of a three conduit distributor.
FIG. 4 is a plan and elevation view of a portion of a conduit showing a typical center port construction.
One unique feature of the process and apparatus of this invention is the combination and interaction of particulate stream splitters, referred to herein as dividers and designated by (7) in the drawings and discharge ports located at various positions along the conduits. The dividers are sized and located in the conduit to divide the particulate into predetermined portions with each portion discharged through a corresponding port to place the desired proportion of the stream at a particular place in the vessel. Each divider can be located adjacent the corresponding port and the stream can be divided in successive operations. In an alternative embodiment, a divider can be extended upstream so that the particulate stream is divided into several portions at one point in the conduit. The discharge ports are preferably of open or non-clogging construction. Preferred ports can be side ports, center ports and terminal end ports.
With the open port construction, extension of dividers upstream and downstream strengthens the conduit. With short dividers and more than three ports, i.e., two or more side ports, the dividing operation is effective to produce successive portions having substantially the same particle size distribution because although the particulate stream is stratified by particle size this stratification extends substantially across the conduit. Thus, a sample taken from the stream flowing down a conduit by a vertical divider is a representative sample and the stratification by particle size extends across the conduit again after the stream flows past the divider. Configuration of the conduit effects the degree to which each particle size layer extends across the conduit. For example with round conduits the five particle size layer would be at the bottom of the stream, with medium size particles in the middle and large particles on top. The five particle size layer would not be as wide as the medium particle size layer and the medium size layer would not be as wide as the large particle layer. With a divider located laterally across the conduit near the center of the conduit this difference in width of the particle layers has little effect on particle size distribution of the various portions. With conduit having a curved bottom this layer effect can be used to divide a stream into portions with the portions from near the side of the stream having a larger portion of large particles than portions from near the center which have a high percentage of fines. With square, rectangular or flat bottom conduits the particle layers extend substantially across the conduit. After a splitting or dividing operation some distance along the conduit is required for the particle rolling or mixing action of the stream to distribute the particle size layers across the conduit. This distance is not critical but is preferably at least about 1-2 conduit diameters. The requirement for this mixing action can be avoided by placing successive dividers and ports on opposite sides of the conduit or in the center of the conduit so that each fraction or portion has the desired distribution.
As used herein, substantially uniform particle distribution means that eachportion separated from a flowing stream in a conduit has approximately the same particle size distributionas the stream except where a device is used to alter that distribution, e.g., screening of the portion. The particle size distribution is determined by any standard method such as ASTM, U.S. Bureau of Mines or Ro-Tap screening methods using Standard Tyleror U.S. Sieve seriesscreens. These methods and the comparison of-the particle size distributions as designated herein are subject to the influence of convention variables and the same degree of accuracy.
The dividers can be located at various positions, i.e., lateral distance from the vertical center line across the conduit, to separate portions of the desired quantity as well as particle size distribution. Likewise, conventional methods, such as screening and grinding, can be used with the process and apparatus of this invention to separate a portion with a particular particle size distribution.
The conduits, ports and other passages of the apparatus of this invention are preferably of open construction to prevent clogging, permit easy cleaning and to give easy access to the interior passages of the apparatus. This open construction is illustrated by the side ports (8), center port (18) and terminal port (9) shown in the drawings. Side port (8) as shown in FIGS. 2 and 3 of the drawings comprises a notch in the side of the conduit (3) so that the conduit is open to the top and side as well as the bottom. Likewise. centerport (18) in FIG. 4 is open at the top as well as the bottom to permit easy inspection and access to the conduit.
With open construction ports the dividers (7) are preferably extended upstream and downstream to strengthen the conduit. These features are not critical and can be modified by one skilled in the art in view of this disclosure. The parts of the apparatus of this invention can be constructed of conventional materials by conventional methods in view of this disclosure. Abra sion resistant material is preferred for abrasive particulate material. For dusty particulate material removable covers can be used for these ports and to cover receiver means (2) allowing openings where necessary for material to enter and discharge.
A preferred distributor means (1) of this invention is shown in FIGS. 1 and 2. In operation of this distributor means receiving means (2) and distributing conduits (3) are supported by hearing means comprising a conventional bearing (5) and a fixed support (4). Optional dust shield (6) is shown over bearing (5). Drive means rotates the receiving means (2) and distributing conduits (3) at about 0.25-5 revolutions per minute (RPM) and preferably about 0.5-3 RPM. The speed of rotation will depend upon the flow rate of the particulate matter through the distributor means, the number of ports the length of the conduits and the characteristics of the particulate material. A chain drive mechanism is shown but any conventional drive mechanism can be used such as shaft and gear, belt, or adjacent motor and gearing. Any conventional motor such as electric or pneumatic can be used.
With the distributor means in operation particulate material is transferred into receiving means (2) from a separate source (not shown) such as a belt conveyor or bucket elevator. Flow of the particulate material is regulated by the shape, size and discharge opening size of the receiving means (2). A simple hopper construction is shown which rapidly transfers the particulate material downwardly by gravity over divider (21) at the inlet end of the distributing conduits (3). Divider (21) sepa rates the stream of particulate material into two approximately equal streams with one stream flowing downwardly through the corresponding inclined conduit (3). Each conduit is inclined at angle (19) so that the particulate material flows by gravity through the conduit. The minimum angle of inclination is equal to the angle of repose for the particulate material which can be determined bystandard methods. The angle (14) is at least 45 and preferably Angles of less than 45 can be used in certain cases where the speed of rotation and other methods for increasing flow such as vibrators are used. Large angles of inclination are preferred for material which tends to stick and for high flow rates.
The stream of particulate material flows downwardly through each conduit where it is divided into two portions by divider (7). These portions are approximately equal and are discharged from the two side ports (8) and two end terminal ports (9). Each of the two side ports is located at a different distance (10) and (11) from the inlet end and axis of rotation of the distributor means so that portions discharged from these ports fall at different points into the vessel (not shown) beneath the distributor. Distances (l2) and (13) between the inlet end and the two terminal end ports (9) are the same but these distances can be different. For different terminal port discharge distances the conduits can be of different lengths, different slopes or can have side or bottom opening ports at any desired point. The conduits should be balanced so that the bearing (5) carries only a substantially vertical weight or force and no appreciable lateral frce or torque. Reaction force of material discharging from the side ports can not be used practically to rotate the conduits with open construction ports and any reaction forces are preferably balanced against each other by alternating side ports from one side to the other.
FIG. 3 shows another preferred embodiment of the distributor means of this invention having an equal three way divider (14) which transfers portions of the particulate material to three conduits having lengths (15), (16) and (17). These lengths can be the same, different or any desired combination.
FIG. 4 shows the detail construction of a center opening port (18) which opens downwardly. The stream of particulate material is divided into three equal portions by the two dividers (7). One portion discharges through side port (8); the middle portion discharges through center port (18) which is open at the top and bottom of the conduit by the symbol (0) and the arrows; and the other portion discharges from a terminal end port.
