ROASTING PERNAGE APPLICIATIOH 11.21) HOV.6,1905.
FRANK KLEPETKO, OF NEW YORK, N. Y
ROASTlNG-FURNAOE.
Specification of Letters Patent.
Yatented March 6, 1906 Application filed November M1906. BBllKl'llO. 28B,Q44,
To all whom it may concern-.-
Be it known that I, FRANK KLnPnrKo, a citizen of theUnited States, residing at N ew York, in the county of New York and State of New York, have invented certain new and useful lm rovements in Roasting-Furnaces, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
My invention has relation to improvements in roasting-film aces and it consists in the novel construction and arrangement of parts more fully set forth in the specification and pointed out in the claims.
In the drawings, Figure 1 is a vertical central section of a conventional McDougall oreroasting furnace, partly broken, with rabblearms disposed ninety degrees apart for C011? secutive hearths, showing a corresponding section of my improvement applied thereto.
'Fi 2 is a cross-section on line 2 2 of Fi 1' i D J and Fig. 3 is a vertical middle section of a rabble-shaft having all the arms superposed,
showing my invention applied thereto.
The object of my invention is to construct a rabble apparatus for ore-roasting furnaces greferably of the conventional turret or Mcougall type, whichfshall be divided into a series of sections or compartments corresponding to the number of hearths of the furnace, each section being cooled independently of any adjacent section by means of a circulating medium injected thereinto from acommon source of sup ly, the said circulatmg medium being disc arged from each section or compartment into a common return pipe or outing, leading from the furnace. The a vantage a such a construction is that the circulating medium may be cut off for such of the hearth or hearths in which there is no longer any danger of injury to or disintegration or destruction of the rabble apparatus from the heat inherent in the charge con tained in such hearth or hearths.
.Referring to the drawings, and partieularly to Fl 3. 1 and 2, F represents the furmace, and the several hearths in which the material is treated, the said material dro plug from the"upper hearth successivey through the several hearths until it is delivcred into the delivery-hop or, (not shown,) the hearths being provi ed, respectively, with the central and marginal openings 1 2 for the passage of the material. Passing centrally through the hearths is the rotatable hollow rabble-shaft 3, from which radiate the series of hollow arms 4, extondin into the several hearths and carrying ra es 5, by which the material is successively fed from one hearth to the hearth immediately beneath it, all as fully understood in the art.
Referring again to the drawings, 6 represents a feeder or feed-pipe, (preferably 'stationar which is located within the shaft, extent in to a point near the bottom of the shaft an dischar ing thereinto, the feeder being supplied wit 1 water from a ipe 6, entering the stuffing-box 7 and lea ing to any source of su ply. (Not shown.) isposed to one side 0 the feeder 6 and mounted in the shaft and extending substantially the full len th thereof is an outlet or exhaust pipe 8,.
sai outlet terminating at the bottom in the space between the inner adjacent ends of the lower pair of rabble-arms. The pi e 8 terminates in a nozzle 8 above the s aft and discharges into a trough 9, though it is apparent that the dischargc waters may be-led to any point where it may be availed of for heati and other purposes. The shaft is divided into a series of compartments or chainbore a l) c d ef g, the chambers being separated from one another by thetransverse partitions 10, occup ing a plane sli htly above the bottom 0 the admcent ra )blearms 4, each chamber having leading therefrom the distributing CODClUltSpI pipes 11, which extend into the hollow arms 4 and discharge thereinto. The intermediate chambers b c d cf (the furnace and shaft bein broken so as to-omit chambers c d) are eac closed at the bottom by a transverse partition 10, which forms (preferably) a continuation of the up or walls of the pair of arms 4 immediately eneath, the lOWGI Cfilllpartment a bein closed at the bottom by the bottom of t e shaft 3 and the upper compartment 9 being closed at the bottom by the uppermost partition 10. By this construction each compartment or chamber ab c dc f g and the pair of arms with which it is in immediate communication (through the conduits 11) is cut off from its adjacent compartment and communicating arms. and, as presently to be soon, the cooling medium (water) in ected or introduced into any compartment or chamber heroines available only for that compartment and its arms and no other. This will be apparent by follow- 8 out past the nozzle 8,
. quantity ing the course of the circulation for the coolmg medium, which is as follows: The feeder (l is open at the bottom and discharges a of water into the bottom eompartment a. The same feeder dischar es water into compartments b e (Z cf throng] peripheral openings 12. ()n the other hand, the outlet-pipe 8 opens at the bottom into the space connecting the lower pair of arms and is also provided with peripheral intake-omnings 13 at points between the partitions It) 10' and also with an o ening 13 in theupper compartment 9 for t 1e escape of the discharge-waters. An inspection of the arrows in Fig. l discloses acirculation asfollows: The water admitted into the com nirtments a b r d, and so on, respectively, through the bottom of the feeder (S and through the peripheral openings 12 thereof becomes heated in its passage through the conduits l1 and bollow arms 4, the heat units abstracted from the walls of the arms (and shaft) as a result of such circulation insuring the preservation of the arms and shaft for an indefinite period. The water having subserved its purpose for each pair of arms is carried off from the lower pair of arms through the bottom of the pipe and from the several intermediate series of arms the water is can ried oil' through the intake-openings 13, (between the partitions 1t) 10,) the discharge from the upper chamber g escapin 1 through the upper opening 13, formed in tihe pipe 8 within said chamber. Thus the arms for each hearth are supplied with a quantity of water from their correspomling chamber or compartment, those of one hearth being independent of the arms of any adjacent hearth. Tue rabble ap aratus as a whole thereby becomes divide( into a series of in dependent sections into which the cooling medium is injected, each section being provided with independent ineans of discharge or outlet.
In Fig. 1 the arms for the different hearths are set at right anglesthat is, each pair is disposed at ninety degrees to its contiguous pair; hut in Fig. 3 I show a form in which the arms for all the hearths are super osed. Being that theonlydifference between t ie two constructions lies in the angular dispositionof the arms, it follows that a description of Figs. 1 and l is equally applicable 1. lflig. I8, aml the same referencecharacters \vill accordingly apply.
An aiialysis of th irculation of the cooling medium makes it obvious that the current leaving the feeder e circulates through the series of arms 4 both vertically and radiallyiii multiple, the inlet means l2and outlet means 13 be ng disposed or distributed substantially throughout the length of the shaft.
Should it be found in the treatment of any ore that the heat inherent in th clu'irge no lon er produces any deleterious effects on the ralflile apparatus after reaching any particu lar hearth, the pipes 6 and 8 may be withdrawn from the shaft and the openings 12 13, respectively, conveying the circulating Ined ium into and out of the arms of such hearth may be plugged up and the pipes reinserted. in this manner the circulating medium may be eliminated or excluded from any section of the rabble appn ratus according to the char acter of the ore subjected to the roasting operation.
