MANUFACTURE or BRIQUETS or COAL,

LQGIWIWII.

Application filed October 3;

to which it appertains to make and use the same.

In manufacturing briquets from coal, coke, turf, iron or other ores or the like it is important that the binding medium should be thoroughly and evenly mixed with the material of which the briquet or brick is made.

In order to attain this object according to the present invention, the binding me dium, mechanically or otherwise atomized or a suitably reduced binding medium is fed to the material of which the brick is made, while the latter is in motion so that all particles of the material are brought into intimate contact with the binding medium. In order to attain this object, the binding material is advantageously blown into or through the falling dust-like material in a direction substantially at right angles to the same as will be hereinafter par- 1 ticularly set forth.

In the accompanying drawings, Figure 1 is -adiagram illustrating the apparatus in longitudinal section, Figs. 2 and 3 show means for rotating or oscillating the mixing drum, Fig. 4 is a modified form of the apparatus, Figs. 5 and 6 are diagrams illus trating other modifications and Fig. 7 is a cross sectional view of the apparatus illustrated in Fig. 6.

Referring first to Fig. l; the organic, liquefiable substance, such as tar, pitch, asphalt or the like is blown into the open end of the i drum in through an atomizing nozzle r from the receptacle 0, the said drum being advantageously inclined so that the material will gravitate toward the outlet end of the same. The drum is is advantageously supported on rolls Z, l which may be rotated in any known manner, for instance, by means ofchain gearing from a motor m. The said drum may also be rotated from a pulley driven by suitable means (Fig. 2) or simply rocked by means of a crank disk n and connecting Specification of Letters Patent.

: rod '(Fig. 3). The drum may also be provided inside with pins or inclined plates 79 (Figs..2 and 3) to assist in mixing'and transporting the material through the same. The atomizing nozzle consists ofthe interior outlet nozzle 9 having a stopper r and the exterior shell 8 forming an annular injecting nozzle which is supplied through a V pipe t with a suitable pressure medium, such a as steam or compressed air. Bymeans of the pressure medium forced through thenozzle, 'the pitch, tar, asphalt or the like is atomlzed and forced into the drum in the form of a dry powder, which, ifthe apparatus is not used for making briquets, may be won or stored as bitumen dust. Baflle plates a displaced as regards each other are advantageously mounted at the outlet end of the drum to catchand throw down the binding medium dust. An exhauster or fan '0 .may be mounted in proximity to the outlet end of the drum, by means of which the pressure medium for atomizing the bitumen may be drawn off and by which means also a slight draft will be produced inside the drum.

In order'to force the atomized or finely divided binding medium substantially rectangularly through the briquet material,

while the latter is showered down in finely divided form, the blades or ribs 72 are provided (Figs. 2 and 3) previously referred to which raise the particlesas the drum is rotated or rocked, and then allow them to fall again, this action being repeated with all the particles during their passage through the drum. An even fall of all the particles is attained by properly regulating the swing of the drum. During this operation the particles of the material will only fall loosely together, so that as thedrum is rotated they will fall without pressure against each other, so that each particle will be properlyv coated with the binding medium. Experiments have shown that the briquets made on this principle are very compact and tight, while there is' no waste of binding medium, thus attaining great economy in the use of the latter.

In the device illustrated in Fig. 4 the material forming the 'briquet is filled into a hopper a, which may be shaken, after the manner of a bolting sieve so that the mateflrial will pass evenly out of the same and fall in the form of a shower.

The material is-then collected in the hopper b and after having been provided with sufiicient binding medium, it may be passed on directly to'the briquet-press. It is however advantageous to employ a bucket elevator c 0 or the like and to pass the material through further hoppers a b a b In order to properly blow in the binding medium in a very finely divided state, it is advantageous to first pass the same through a wind or blower separator, as used for fining flour and indicated at d, the pitch ll aving this apparatus at e in the form of fine pitch dust and passing into a storage receptacle f whence it is fed by a plate h in suitable quantity to the injecting nozzle 8. The coarser powder passing out at the bottom of the apparatus (1 may be ground again and again fed in or used for other purposes. The nozzle 8 serves also in this case as a compressed air or steam jet to force the atomized material substantiallv at right angles through the falling briquet material. There will be practically no friction between the particles which simply fall one on the other into the hoppers b, 6 b

In Fig. 5 a further modification is illustrated in which the material passes down a series of steps 2' which are shaken or vibrated by suitable means, so that in this case also the jet meets the material substantially at right angles. The short sliding movement of the particles on the steps '5 will not interfere with the coating of the same since the layers are very thin and the friction consequently very slight. I

In Figs. 6 and 7 a modification is illustrated in which the material, similar to the device shown in Fig. 1, is fed into a drum k provided withblades or ribs ;0 and in which the binding medium is employed in a liquid form. In this case the atomizing is effected by means of a perforated pipe to extending into the interior of the drum so that as illustrated in Fig. 7 the jets of the binding medium will meet the falling material and be blown through the same substantially at right angles.

The above described process and apparatus may be employed in connection with any kind of binding material, which may be atomized or reduced as previously mentioned either mechanically or in other suitable man- It may be mentioned that if a liquid binding medium is introduced by means of an injector nozzle or the like, the briqueting material and the binding medium may be combined immediately beyond the nozzle, so that the particles of the binding medium will combine with the particles of the briqueting material while still in a finely divided liquid form.

It is self-evident that the binding medium may be blown in, in the manner described with reference to Fig. 1, in that the binding medium particles are first converted into dry dust and then brought into contact with the briqueting material being sprinkled in.

I claim as my invention 1. The herein described method of manufacturing briquets, which consists in feeding l riquetn1aterial into a container, moving said container to give the briquet material therein a rotary rising and falling motion, whereby said material is loosened and agitated without stirring the same and spraying a binding material into said briquet material in a direction substantially at right angles to the falling motion of the briquet material.

2. In an apparatus for the admixture of briquet material with bind ng material, the combinatlon with an inclined drum open at both ends, of means for moving said drum to give its contents a rotary rising and falling motion, means at one end of the drum for spraying thereinto a binding medium in a direction substantially at right angles to that in which the contents of the drum fall, and a series of staggered baffle plates at the opposite end'of the drum.

In testimony whereof I hereunto atfix my signature-in the presence of two witnesses. EMIL KLEINSCHMIDT. \Vitnesses JEAN GRUND, )ARL GRUND.
