Definitions

  • the drum As the drum totates it carries a thin layer of liquid on the surface portions not immersed in the liquid and also agitates the liquid in the tank.
  • the powder is carried in a feeding hopper and discrete particles are discharged to the layer of liquid carried by the drum and thereafter the individually wetted particles are discharged into the liquid in the wetting tank where it starts to form a solution.
  • the solution flows through the discharge mechanism and into a separate aging tank where the solution is finally formed.
  • a special spreader nozzle is used to spread the particles along a straight line on the drum.
  • This invention is, therefore, directed to a system and apparatus for economically and efficiently producing liquid solutions from particles of dry powder and, particularly, from particles of dry powder that must be individually wetted. Briefly, this is accomplished in accordance with this invention by providing a wetting tank, including a liquid supply and discharge mechanism and a rotary drum which is only partially immersed in the liquid contained .in the wetting tank. Rotation of the drum causes it to carry a thin layer of the liquid on any surface portion not immersed in the Iiquid.
  • the dry powder to be mixed with the liquid is carried in a feeding hopper and particles of the powder are fed to the layer of liquid carried on the drum where they are individually wetted and thereafter, discharged into the liquid in the wetting tank.
  • the drum also causes agitation of the liquid which further facilitates the dissolving of the particles in the liquid. Eventually, the liquid and particles are fed to the aging tank until they form the solution desired.
  • Another aspect of this invention is directed toward a novel spreader nozzle which can be used in any feeding system, but which is particularly useful in conjunction with the system described above for evenly distributing the particles on the rotary drum.
  • the nozzle includes a receiving surface on which the particles are deposited and an inclined spreader surface over which the particles are distributed fromthe receiving surface. Diverging side edges extend along the spreader surface from the receiving surface toward a guide surface which determines the configuration in which the particles are deposited on the drum or other surface on which they are to be deposited. While the configuration of the guide surface can vary, the preferred embodiment utilizes a straight edge so that the particles fall on the drum in a straight line covering substantially the entire length of the drum.
  • FIG. 1 is a perspective view illustrating a system in accordance with this invention
  • FIG. 2 is a perspective view with portions omitted for the sake of clarity of a spreader nozzle which can. be used in the system illustrated in FIG. 1;
  • FIG. 3 is a front view of the spreader nozzle illustrated in FIG. 2;
  • FIG. 4 is a side view of the spreader nozzle illustrated in FIG. 2.
  • Feeding device 10 may be any of a variety of conveyor type mechanisms, but the preferred embodiment includes a hopper 11 in which the powder is stored and could also include a conventional type of vibratory mechanism (not shown) for keeping the particles from packing together in the hopper. Use of a vibratory mechanism depends, of course, on the cohesive tendencies of the particles.
  • a discharge pipe 14 having a discharge spout 15 extending outside the hopper.
  • a suitable conveyor such as a helical feeder or screw feeder for conveying the particles from hopper 12 to discharge spout l5.
  • Adjacent discharge spout 15 is a spreader nozzle 16, the details of which will be fully explained hereafter. At this point it should merely be noted that nozzle 16 distributes the particles evenly along a straight line, is not necessary for the invention but allows for a material increase in the feeding rate of the powder.
  • Wetting tank 12 is in the form of a receptacle adapted to contain the liquid, generally water, with which the powder is to be mixed. Accordingly, wetting tank 12 is provided with a liquid conduit 18 connected to a suitable source of the liquid and having branches 18a and 18b extending into the tank. Conduit 18 includes a rotameter 20 which measures the flow rate of the liquid in a conventional manner. While rotameter 20 is not required, it should be noted that some type of flow rate indicator should be provided so that the delivery rate of the liquid can be adjusted.
  • Branch conduit 18a is located adjacent one wall of wetting tank 12, extends across the width of the tank and includes a series of holes which uniformly distribute: the liquid as a spray inside the tank; branch conduit 18b is spaced lengthwise from branch 18a, also extends across the width of the tank and also includes a series of holes (not shown) which distribute the liquid as a spray inside the tank. Only a single branch conduit could be utilized, but as will become clearer hereinafter, use of the two branches will minimize the effects of the duct formed by the particles fed to the tank.
  • conduit 22 that communicates at one of its ends with the interior of the wetting tank and at its other end with a jet type pump or ejector 24.
  • conduit 22 is coupled to the bottom wall of a projecting portion 19 extending from the main portion of wetting tank 12, but having a depth substantially less than that of the main portion. Accordingly, a predetermined level of liquid is maintained in the wetting tank.
  • ejectors discharge a jet of liquid across a suction chamber through a diffuser along with the liquid.
  • ejector 24 is connected to conduit 18 through a conduit 23 including a control valve 25. When the control valve is open, liquid is discharged through ejector 24 sucking the solution in the wetting tank through the diffuser and into aging tank 13.
  • various other types of discharge mechanisms could be utilized, for example, an overflow spout.
  • Extending across the tank 12 adjacent and below branch conduit 18b is an imperforate cylindrical drum 26 which is rotated by a drive motor 28 located outside the tank. As illustrated in the drawing a portion of drum 26 is located below the surface of the liquid maintained in the tank and the remaining portion is located above that surface. Rotation of the drum by drive motor 28 agitates the liquid in the tank and also causes a thin uninterrupted layer of liquid to adhere to the portion of the drum not immersed in the liquid during the rotation, that is, any small segment extending along the length of the drum will, as it first emerges from below the surface of the liquid, pick up and carry a thin layer of liquid. As the segment continues along its path of travel, the layer of liquid is carried along until just before the segment re-enters the liquid where it will be hurled from the drum and into the liquid.
  • a preferred driving speed for the drum is approximately 400 revolutions per minute.
  • particles discharged from feeding device are directed downwardly as a stream toward the surface of the drum so that they contact the layer of liquid which, of course, wets each particle. Relative movement between the particles and the drum assures that particles are not deposited on top of each other but are always fed to a different portion of the drum. As the drum continues its rotation, an individual particle which has been wetted is then hurled from the surface of the drum as the drum approaches the liquid and continues its movement in the liquid due to the agitation of the liquid caused by the drum. It is desirable to rotate the drum in a counterclockwise direction as illustrated by arrow A in FIG.
  • Aging tank 13 could be of any construction capable of receiving and holding a solution until the particles are completely dissolved.
  • tank 13 comprises a receptacle having a volume so as to hold the solution for a predetermined time, usually one to two hours, and having an open top located below the open end of conduit 23 on the discharge side of ejector 24 so that the solution is discharged from wetting tank 12 into the aging tank.
  • a mixer 32 is provided and operates at relatively low speeds, for example, less than about 400 revolutions per minute.
  • a suitable discharge mechansim is provided for removing the solution from aging tank 13 and in the preferred embodiment described herein, includes a conduit 30 communicating with the inside of the tank adjacent its bottom surface and a suitable transfer pump 31 including a drive motor 33.
  • a suitable overflow spout could be provided adjacent the top of the tank.
  • FIGS. 2 through 4 there is disclosed a spreader nozzle 16 capable of being used in the above described or other particle feeding systems. While it was noted previously that nozzle 16 is not necessary for the operation of the system described above, it has been found that a nozzle of this type allows for significantly increasing the feed rate of particles through a discharge spout by distributing the partciles along a straight line rather than in a narrow stream.
  • spreader nozzle 16 includes a flat particle receiving surface 34, a generally inclined spreader surface 36 and a guide surface 38.
  • Spreader surface 36 actually is a segment of an imaginary frusto-cone C, as best seen in FIG. 2, so that it is generally arcuate in cross section and has a pair of edges and 42 diverging from receiving surface 34 to guide surface 38.
  • the shortest width of spreader surface 36 is adjacent receiving surface 34 and its longest width is adjacent guide surface 38.
  • the included angle between edges 40 and 42 should be equal to or just slightly smaller than the angle of repose of the powder being distributed. Obviously, however, this angle varies slightly for different powders and, thus the angle is selected to be just equal to or slightly smaller than the smallest angle of repose for the materials anticipated to be distributed.
  • Receiving surface 34 can be generally perpendicular to the longitudinal axis of frusto-cone C, but in the preferred embodiment is slightly inclined so that it forms a small angle with a plane perpendicular to the longitudinal axis of the frusto-cone. Accordingly, as best seen in FXG. 2, receiving surface 34 intersects spreader surface 36 along an arcuate edge.
  • guide surface 38 is a substantially flat surface extending generally parallel to the longitudinal axis of frusto-cone C. It should be understood, however, that guide surface 38 need not be flat, but that its configuration can vary depending on the distribution pattern desired for the particles being discharged.
  • side walls 44 and 46 are formed along edges 40 and 42, respectively, and function to confine the particles to spreader surface 36, as will be fully explained hereinafter. Walls 44 and 46 also extend along the sides of receiving surface 34.
  • spreader nozzle 16 is secured, by any suitable bracket, to the end of discharge pipe 14 so that receiving surface 34 is adjacent to and below the axis of discharge spout 15.
  • the particles discharged through the open end fall on receiving surface 34 where they form a conical pile of powder until the included angle between any two sides of the cone in longitudinal cross-section is equal to the angle of repose for the particles.
  • additional particles fall on the pile they slide over the sides of the pile and are uniformly distributed down along spreader surface 36 which conforms generally to the configuration of the pile except that its sides have an included angle slightly smaller than the angle of repose.
  • the particles fall from spreader surface 36 they are guided by guide surface 38 and, therefore, assume its configuration when they strike drum 26 or other surface on which they are deposited.
  • guide surface 38 Since guide surface 38 is flat, a straight line configuration of particles is formed on the portion of the drum on which they are deposited. If surface 38 had another configuration, the particles would assume it when they struck the surface of drum 26. For example, if surface 38 were convex, an arcuate convex configuration would be formed on drum 26 by the particles. As noted previously, walls 41 and 46 confine the particles to spreader surface 36.
  • the particles fall along a generally straight line extending substantially the length of drum 26. Accordingly, the feed rate of the particles can be increased and more of the drum surface is utilized which adds to the efficiency and economy of the system.
  • a system for wetting discrete chemical particles including a wetting tank in which the particles are to be wetted, means for feeding the particles to said wetting tank and an aging tank for receiving solution from said wetting tank, the improvement comprising:
  • a rotating drum located in said wetting tank and being partially immersed in a liquid which adheres to the surface of said drum as it rotates and which agitates the liquid in said tank, said drum being located below said feeding means so that the particles are fed to the layer of liquid on the drum whereby each particle is wetted and thereafter mixed into the liquid in said tank.
  • said wetting tank includes liquid supply means and discharge means whereby liquid is supplied to said tank and a solution including said liquid and said particles is dis charged to said aging tank.
  • said liquid supply means includes a conduit extending into the interior of said tank and which is formed with a series of openings for allowing the passage of liquid into the tank at points spaced along the interior of said tank.
  • liquid supply means includes a plurality of conduits extending into the interior of said tank, one of said conduits being located adjacent to and above said drum.
  • said discharge means includes a conduit communicating with the interior of said wetting tank and an ejector means for discharging said solution to said aging tank.
  • said feeding means includes a nozzle for distributing the particles along an elongated line extending substantially throughout the length of said drum.
  • said nozzle includes an inclined spreader surface over which said particles slide, said spreader surface having side edges that diverge from a smaller width to a larger width closer to said wetting tank.
  • said nozzle includes a particle receiving surface adjacent said smaller width of said spreader surface and further includes a guide surface adjacent said larger width of said spreader surface.
  • said spreader surface is a segment of an imaginary frustocone and wherein said particle receiving surface forms a slight angle with the plane generally perpendicular to the longitudinal axis of said cone.
