7 Gla.

The present invention relates to an apparatus for spraying material, and while the invention contemplates the spraying of any suitable material with any suitable liquid it is particularly adapted for the spraying of soft or hard coal with oil. An object of the invention is to provide an apparatus into which the coal or other material may be flowed or poured in the form of a confined compact .stream, and within the apparatus will be spread into a thin layer as it flows therethrough, the oil or other liquid being sprayed thereon in a manner to substantially completely cover all particles thereof with an even film or coating, and without any waste due to evaporation, misting, or the like, the sprayed 0091 being themfiowed from the apparatus in a confined compact stream. It is particularly proposed in the exemplary illustrated embodiment of the invention to provide a chamber into which.

the coal is flowed and within this chamber to provide spreading means which will cause the flowing coal to assume a thin-walled globular shape, 'and further to provide oil spraying means arranged both within the globular shaped flowing coal and also at its outer surface so that all particles of the coal will be reached. A further object is to dispose the oil spraying means so that they are entirely protected against contact with the flowing coal and will not therefore become clogged or impaired thereby. Another object, is

to provide an apparatus of simple construction, which may be readily attached in relation to a ,conveyor or other coal feeding means, and which may be conveniently transported when desired from one part of a plant to another. A further object'is to provide an apparatus which may be easily and conveniently disassembled for clean- Fig. 2 is a plan view of the apparatus, partially broken away.

Referring to the drawing the material spray- (Ci. 9L-44) ing apparatus, according to the exemplary illustrated embodiment of the invention, comprises a spraying chamber consisting of a lower inverted cone shaped wall Ill, having a cylindrical vertically extending upper wall portion H, and. provided at its base with a cylindrical outlet wall l2. Secured to the upper marginal edge portion of the cylindrical wall portion I2 is an angular flange member it upon which there is removably secured the upper portion of the chamber consisting of a cone shaped wall member it provided at its edge with an angular flange member l5 which seats upon the flange member 83 and is secured thereto by screws it. A cylindrical material inlet neck portion H is provided at the upper edge of the wall portion. M, and a diverging inverted cone shaped funnel portion it is mounted upon the neck portion fll.

Surrounding the cylindrical wall portion 6 l there is provided an oil feeding header pipe 89, provided at equally spaced points with inwardly directed jet nozzles 20 extending through holes 28 in the wall portion H in order to direct the sprayed oil into the chamber, the angular relation of these jet nozzles being so arranged with respect to the angles of the conical wall portions I ll and I l that the spray will spread to all parts .of the chamber.

Within the'chamber directly below the neck portion I! there is provided a cone member 22 provided at its under side with an interiorly threaded boss 23 which is secured upon the upper threaded end of a vertically disposed pipe 2d, this pipe being mounted at its lower end upon a bracket arm 25 secured to the wall portion it. The pipe 24 is provided near its upper end within the space below the cone 22 with a series of downwardly inclined jet nozzles 26, and at its lower end is connected by suitable couplings 21 and 28 to an oil feeding pipe 29 extending through a hole 30 in the wall portion In.

While the coal or other material to be sprayed may be fed into the chamber in any suitable manner it is preferably fed by means of a conveyor belt 39 extending over a roller 32, having its shaft 33 mounted in bearing brackets 34 secured upon a pair of beams 35 disposed above the chamber and upon which the chamber is suspended by, a series of rods 36 secured at their upper ends to the beams 35 and removably secured at their lower ends to angular brackets 31, secured upon the cylindrical wall portion l l of the chamber, by means of nuts 38 engaged upon the lower threaded ends of the rods.

The operation of the apparatus is as follows;--

The coal or other material to besprayed is fed by the conveyor to the funnel Hi from which it passes through the neck I! in the form of a confined compact stream. From the neck I! it drops upon the cone 22 and is spread thereby into a thin even layer which passes from the cone downwardly tothe wall portion l0 and is again converged at the outlet I2 into a confined compact stream. It will be seen that the coal as it flows through the chamber is in the form of a thinwalled globular body of flowing coal, so that all particles thereof are exposed either at the outer or the inner surface, bothof which surfaces are of relatively large area. The oil sprayed by the outer nozzles 20 covers substantially all of the outer surface of the'flowing coal, while the oil sprayed by the inner nozzle 26 covers substantially all of the inner surface, and due to the flowing movement of the flowing coal particles and the spreading of them over the large area globular surfaces there is a complete and even spraying of all particles of the coal by the oil. Also the oil is entirely confined within the chamber, so that there is no loss due to evaporation, misting, or dripping, and all of the sprayed oil deposits on the surfaces of the-coal particles. Also the arrangement of the nozzles 20 in surrounding outwardly spaced relation to the flowing coal and the nozzles 26in the protected space below the cone 22 is such that the nozzles are entirely out of contact with the flowing coaL and therefore will not become clogged or impaired thereby.

In order to clean the apparatus it is only necessary to remove the screws l6, whereupon the top section can be readily removed. Also the cone member 22 may be screwed oil! of the upper end of the support 24, so that access may be had to all of the spray nozzles.

We have illustrated and described a preferred and satisfactory embodiment of the invention, but it will be obvious that changes may be made therein, within the spirit and scope thereof, as defined in the appended claims.

Having thus described our invention, what we claim and desire to secure by Letters Patent is:
