APPARATUS FOR TREATMENT OF BONE-BLACK.
SPECIFICATION forming part of Letters Patent No. 538,028, dated April 23, 1895,;
Application filed July 16, 1892- Serial No. 440,210. (No model.)
. To aZZ whom it may concern.-
Be it known that I, EDWIN A. SORIBNER, of Elizabeth, in the county of Union and State of New Jersey, have invented a new and useful.
Improvement in Apparatus for the Treatment of Bone-Black, of which the following is a specificationj The special object of my invention is to remove the oil from the spent bone-black of oil refineries, so asto prepare it for use in the manufacture of fertilizers, and at the same time to use the heat generated by the combustion of the oil for making steam, distilling oil, evaporating or other purposes. r
Heretofore the spent bone-black saturated with oil has been sold to be mixed with acid in the manufacture of superphosphates. The presence of the oil lowers the grade, and also retards the chemical action between the acid and the bone-black. The high fire test of the oil in spent bone-black has heretofore rendered itdifficult to burn it.
My invention consists in means for causing the saturated bone-black to fall in a finely divided state through a vertical combustion chamber, the oil being consumed during the descent of the material; 'and in conducting the products of the combustion away through suitable fines, as hereinafter more fully set forth.
A practical embodiment of my invention is represented in the accompanying drawings, in which-- Figure 1 represents in vertical section, the upright combustion chamber and a connected system of fines, together with a system of steam boilers for utilizing the heat; and Fig. 2 represents the structure in horizontal section.
' A is the vertical combustion chamber, preferably formed inside a vertical chimney about twenty-five feet in height.
Bis a horizontal flue connected with the combustion chamber by the vertically extend.
ing-flue C, and leading to the auxiliary stack or uptake D. The fine B is provided with bridges 1), 17,17, forming dust pockets to collect the dust carried over by the draft; and also with openings E,E leading into flues that connect with the combustion chambers of two steam boilers, these openings being provided with dnmpers F, F, to control the amount of heat allowed to pass to each.
The combustion chamber in the vertical chimney is provided, near its upper end, with inclined plates G, G. Just under the plate G is the feed aperture, through which the comminuted bone-black is introduced from the hopper H by means of a feed screw I or other suitable mechanism.
The manner of operating, so as to attain the best results as to grade of bone phosphate and economy of the products ofcombustion for heating purposes is as follows: I elevate the oil-saturated bone-black or other material by a bucket elevator, run by the shaft and pulley J, into the hopper H, and the screw I feeds the material into the combustion cham ber in quantities regulated by the speed of the screw. To carry the material into the middle of the chamber, it may be caused to strike upon an inclined tile K, from'which it rolls off and falls through the chamber, the oil being thoroughly burned out during the descent, from each successive portion of the material meeting a constant flame generated by the burning of preceding particles. The purified bone-black finds an exit through the opening L, where it may be taken by elevator buckets and removed to any desired place to cool. The initial flame may be produced by burning some light oils or kindling a wood fire at the openingL, and adding alittle oil black; or the first portion of the material discharged into the combustion chamber may be mixed with naphtha, and ignited as it enters the chamber. The continued introduction of fresh material and consequent constant fiame produces an intense heat which is carried by the draft which enters at the opening L over the bridge wall M, down the flue O and along the fiue B.
The inclined plates G, G are to reflect the dust as much as possible and prevent it going over into the fines. The finer particles carried over are collected in the chambers of flue B and are removed at times through suitable doors. For some heat using appliances it may be desirable to vary the form of dust chambers. I
The openings E, E connect the flue B, 10-
cated below the level of the ash pits of the boilers, with the fines N, N leading to the combustion chamber of the boilers. The dampers F, F, of tile or other fire proof material, can be raised or lowered at will to open or close the openings, makingit possible to conduct the hot current to either boiler or to both, or to shut it off altogether. After passing over or about the heating surfaces it passes to the fine that leads to the stack of the boilers. \Vhen all the openings E, E are closed, the products of combustion will pass 01f through the auxiliary stack D; but the base of this stack may be entirely closed by the damper R in which case of course the dampers F, F, or some of them, must be open.
The bridges 0,0 are to keep the coal on the grate bars P, from falling into the fines. As the heat is very great, it is not possible to bring it in contact with the grate bars of the furnaces without rapidly burning them out. This is. a reason for introducing the products of combustion into the combustion chambers above the grate bars. I prefer to have grate bars, as shown in Fig. 2, in order that coal may be used whenever the. operation of burning the oil is discontinued becauseof lack of'supply or for other reasons.
The walls of the combustion chamber A should be lined with fire-brick throughout and be of suflicient thicknessto retain theheat.
It is possible to heat iron red hot at a distance of fifty feet or. more fromthe combustion chamber, by the heat produced by the combustion of the oil in waste. bonerblack by my apparatus.
What I claim.is-
l. Theherein described apparatus for the treatment of bone black, comprising a vertical chimney for the reception of the bone black to be treated, means for feeding the bone black continuously into the upper portion of the chimney, an inclined tile for receiving the bone black. as it is fed into the chimney fine for spreading it and distributing it in a conveniently divided state to promote combustion, inclined plates located Within the fine above the feed aperture for arresting the upward movement of the substance under treatment, the chimney being further provided with a second vertically extending flue through which the products of combustion are forced to pass and means for conducting the products of combustion from the second vertically extending flue to an uptake, substantially asset forth.
