To aZZ whom, it vm/zj concern.-
Be it known that L' GoDFREY HUGHES, residing atEl Paso, in the county of El Paso and State of Texas, have madecertain new and useful Improvements i of which the following is a specification.
My invention is an improvement in calcinefurnaces; and it consists in certain novel constructions and combinations o f parts, as Will be hereinafter described, and pointed out in the claims. f
In the drawings, Figure 1 is a vertical section of an apparatus embodying my invention. Fig. 2 is a top plan view thereof, a portion of the chute being broken away. Fig. 3 is a detail side View showing a portion of the chute. Fig. 4 is a detail perspective view' illustrating the operating-chain and its projection for tipping the vibrating plate; and Figs. 5, 6, and 7- are respectively top plan, front edge, and side views of the vibrating plate.
In the construction as shown I employ a" furnace A, a stack B, and an inclined chute C. The furnace may of itself be of any de` sired construction suitable for the purpose and discharges its fumes and other products into the lower end of the chute C, the upper end of such chute communicating with the stack B about in line with the upper end of the elevator D, which receives the discharge from a suitable crusher E and delivers it into the upper end of said chute. The elevator D preferably discharges onto a detlecting. or spreading plate F, which is ribbed, as indicated in Fig. 2, or otherwise'suit-` ably constructed to4 distribute the material.
received from the elevatorD onto the uppermost onevof a seriesV of vibrating plates G, which are supported in the chute C and being Valike in construction the description of one will answer for all. The plates G are arranged in anq inclined position, one slightly above the other, and retreat gradually' toward the upper end of the series, the series of vibrating plates being thus inclined to correspond with the inclination of the chute C, as shown in Fig.` l.
As shown in Figs. 1 and 3, the vibrating plates G are pivoted between their front and rear edges at G', such pivot being preferably so arranged that the front edge of the plate in Calcining-Furnaces,'V
Vsupported and driven by moving parts ofthe apparatus and has t-he where it discharges overbalances the portion of the plate in rear of the pivot G, so the discharge edge of the plate G will drop by gravity from the position indicated near the bottom of Fig. 3 to that indicated near the top of said figure whenthe projection on the operating-chain H has passed out of engagement with the vibratingplat@ The plate G is provided at g with flanges which prevent the material from passing olf the sides or rear edge of the plate G,'the front edge of such plate being unobstructed, so the material can freely pass or discharge from each plate to the next lower one, the discharge edge of each plate lying vertically above ythe next lower plate and preferably over a point slightly in rear of the pivot G of the said lower plate, as will be understood from Figs. l and 3.
Stop-pins I areprovided and extend laterally from the plate G, at or n ear its discharge end, such pin projecting through slots Jin the chute and one of the pins being provided with a roller K, which forms a theprojection II on the chain I-I, as will be understood from Fig.` 4t. Chain H is suitably gearing with other projections H suitably spaced apart to secure the desired operationof the vibrating plates. To insure the proper operation of the plates by the projections onrthe chain, I provide supporting-guides L, which maybe carried by the chute or otherwise suitably supported and are arranged opposite the 4bearings K in such a manner as to support the chain while its projections H are in operative contact with said bearings, thus avoiding any sagging of the chain at such time and insuring the proper operation of the vibrating plates by the movement of the chain, as will be understood from the drawings.
The chute C has a discharge at C", through whichthe roasted ore may be discharged into a car or other suitable receptacle placed to receive it, as is best shown in Fig. l of the drawings. f
In the operation ot' the apparat-us the ore from the crusher is taken from the elevatorbuckets and delivered onto the detlectingplate F, which distributes it upon the uppermost one of the vibrating plates in a thin IOO layer. The ore is here rst subjected t a low dull dark-red heat, as it is some distance from the furnace. The ore is then discharged step by step from one vibrating plate to the next lower one until it is discharged'atthe" bottom of the chute. The plates Gr areson` @imaged 'as to secure a uniform and per;- fect"1oasting of the ore. r'llhus iftheores are found to roast too fast the number'of 1o tripping projections or dumping links Ii' in the chain H may be increased, thereby hastening the transit of the ore from the tgp tipping-plate to the bottom andthence to the car.v On the other'`v h'ad,iff the" oreV roasts 415 slowly the number of dumping-links can` be reduced until the transit of the ores can be slowed down suiciently tosecure the perfect, roasting. f
