PORATION, or CLEVELAND, omo, A.CQRPORATION or OHIO CUIOLA.
Application filed July 24, 1926." serial No. 124,655.
The object of the invention is to provide improved and very simple draft effecting means for the better operation of cupolas and to provide a componentstructure adapted for successive employment with each of a series of cupolas or the like, at times of their respective operations; and, to keep the heat within reason; and which shall serve to catch and remove the dust that would wear out the draft inducing mechanism and which, if not removed, would be thrown into the surroundin air to the annoyance and injury of neigh oring persons and property.
The invention comprises and comprehends both the novel method and the novel draft inducing and dust collecting means hereinafter detailed; and will be readily understood upon referenceto the drawings that form part of the specification.
In said drawings, Fig. 1 is a vertical elevation of a cupola structure or the like, both illustrating and embodying the invention; and, Fig. 2 is a side elevation thereof.
As indicated in the drawing, the invention is adapted for use in connection with two or more cupolas or low stacks, marked A in the drawing. An elevated track B parallels the row of cupolas at one side thereof and preferably above the roof C of the cupola house. On this track and for operation from end to end thereof is a car or trolle D which carries the dust collector proper also a suction fan F connected with the outlet of the collector E, and, suitthe electric motor G.
Either the dust collector may have a bracket-like hood or cap to drop over the open top of the cupola; or as preferred, each cupola is provided with a hood or ca H. Each hood is suitably flanged, as at I to meet and be connected with the flange E belonging to the intake E" of the dust collector E. The row of flanges H parallel the track B, and the trolley D, being moved along the track, may be positioned to connect any one of the cupola hoods H with the dust collector E.
The cupola selected being in operation 50 and the collector being connected therewith able fan and trolley driving means, such as as described, the suction fan F is operated to induce, augment and regulate the draft through the cupola. Such use of the equipment is important from the standpoint of both increasing and nicely governing the working capacity and the operation of the cupola.
Where the permanent stack tops or caps H are employed, each thereof should be pro.- vided with a door or vent opening K and a swinging door K, which may be opened when access is required to the top of the stack, or when it is desired to discharge the stack gases direct to the atmosphere, or more importantly, when it is desired to admit cold air across the top of the cupola for the purpose of markedly varying the draft and rotecting the dust collector and blower f fom destructive heats in the cupola. The common smaller variations of draft are accomplished by varying the speed of the fan motor, G.
As will be understood by those skilled in the art, the materials are charged into the cupola through the door in the side thereof, above the charging floor; and, the combustion is maintained by air blast through tuyers (not shown) leading inward from the pressure air trunk, L, at the bottom of the cupola. Thetrunk is supplied with air from a pipe M, which in turn receives the pressure air from the usual readily con trolled and suitably valved blower system.
Attention has been called to the benefits that are secured by definitely measuring and controlling the draft and which is now feasible by the employment of the heat-and-dustprotected suction fan. To these advantages must be added that of the effective regulation ofthe combustion by the control of the combustion air simultaneously with the control of the suction draft, whereby the melting capacity of the cupola can be greatly increased. And incidentally the temperature and pressure conditions at the charging door may now be controlled to completely suppress the common annoying and dangerous flashing of the gases above the cupola charge. Further, because of the described admission of cool air, the final hea t or blowing down of the charge may now be carried'out without detrimenta-lly overheating the cupola top or burning out the parts comprising the draft inducing equipment.
At one end of the elevated structure is a deep pocket I and when the collector has been filled with dust the trolley is run, to that end of the structure and the collector E is emptied into the pocket I. 'Fromthat point the dust is disposed of b jway'pf the valved; down spout J, the "dust usually'being dis charged into a waiting car.
ing cooled air simultaneously with the smoke,
and driving means also movable with said collector.
In testimony whereof I have hereunto set my hand this 23rd daiy of-July, 1926.
