PEAT DRIER AND THE LIKE.
ApplicationA lred December To all tolto/m t may concern:
` n Be it known that I, JOHN LUMsDnN, a `subject of the King of Great Britain, and
resident of the city of Ottawa, in the Province of Ontario and Dominion of Canada,
Vhave invented certain new and useful Improveniente in Peat Driers and the like, of which the following is a specification.
This invention relates to improvements in peat driers, and the objects of the inven- Vtion are to provide a new, simple and economical means for effectively drying peat fuel.
A further object is to provide practical means of this character that, in comparison with means heretofore generally recognized and adopted, will give most satisfactory results for much less expenditure.
`A` still further object is to provide a drier of this character adapted to be used in combination, not only with any well-known method of heating and delivering the air thereto, but also in combination with a new and improved method as herein illustrated, whereby the surplus heated air from a furnace or boiler, which would otherwise be wasted, is here not only conveyed to the drier, but also is tapped on the way to increase its volume and regulate thetemperature to meet all requirements.
Another object is to provide a drier of this character that may be used in any suitable position, either singly,in pairs, or in series, with equally satisfactory results.
Another object is to provide a drier of this character in which the heated air is injected `at the opposite end to the feed or supply end With these and other objects in View, hereinafter more fully described, the invention consists essentially of an improved drier for peat and the like comprising a suitable casing with rotatably mounted spiral beaters or blades therein adapted, in rotation,to lift,
carry and sift the material in the drier whereby, in combination with the surplus heated air from a furnace Vor the like,\the peat is dried and discharged therefrom, means for supplying and `discharging the drier, means for ejecting the moisture- `charged air therefrom, and means for operating the beaters.
Referringto thedrawings, in which like characters of reference indicate corresponding parts in each figure, and in which: l
Figure 1 is a side elevation of the drier i6, 1921. serial No. 520,368.
arranged in connection with a furnace and a second drier.
Figure 2 is a top view.
Figure 3 is an end view.
Figure 4 is a cross-sectional detail of th drier. Y
In the drawings:
A pair of driers A and B are shown PN nected respectively to furnace and fan means for supplying the heated air to the drier.` These driers are similar in construction and, here shown, arranged in pairs in staggered relationship to one another. They can, however, alsov be used singly or in series, arranged in any convenient and suitable manner.
The'drier A comprises a cylindrical casing 10 with feed and discharge hopper openings 11 and 12 at opposite ends thereof. 13
p are blades or beaters keyed to the shaft 14 Aextending through the casing 10 on suitable bearings 15 and 16 and beyond said casing on the supports 17 andlS to connect through the pulley 19 with the source of power. 2O is another pulley on the shaft 14 at the end thereof, belt connected as at 39 to the pulley 21 on the shaft 22 of the drier B.
The beaters or blades 13 are spirally formed at 23, and are provided with wire mesh or netting extensions 24 partially curved at their outer ends 25 in spaced relationship in rotation to the inside ofthe casing 10.
26 is al suitable fan of any well known constructionarranged to force air through connection 27 into the discharge end of the drier A, while 28 is an exhaust pipe for the incisture-laden air after it, as heated air, has been forced through the peat, agitated by means of the rotary beaters 13 within the cylinder lor casing 10. 29 is a fan pulley to be connected to the source of power. 30 is a conveyer from the discharge opening 12 of the casing l0.
The drier Binstead of being supplied with heated air in any well-known manner and as shown and employed in the case of the drier A, obtains heated air by a new and improved method from the boiler or furnace of the plant, utilizing from this source the surplus air therein by means of the fan and outlets -31 and 32 arranged at'the end of the drier proper B in combination with a suitable conduit 33 connected at 34 to the boiler in such manner as to receive therefrom the waste products of combustion.
This conduit 33 is connected at its outer endr through the fan 31 Vand blower 32 to deliverv the furnace heated'air to .the drier B.
36 is an air inlet-*inthe conduit 33 provided with a suitable closure 37, preferably a sliding door (as shown), whereby the cool air may be taken in ,toV the conduit to increase the volume of the' air therein and 'at the Sametime to reduce the temperature to a workable degree that will not ignite or cause ignition of the peat in the drierMB when said air is forced thereinto. '3 8 is the fan pulley and 28?. an exhaust. i `'From the foregoing, the operation of my drier will be apparent. With the plant in operation, the moisture-laden peat,'having been "ground, in any well-known manner, is delivered in this case firstto the drier B and then preferablyV by gravity through a conduit-39 to the drier and is there again subjected tothe action of the rotatable beaters 1,13 in conjunctionwith a volume o f fan-driven heatedair from the opposite end of same. The combined action of the heated air coming Vinat one end and the agitation Yof the P-ali @Ommencing at the other, causes it to be thoroughly and rapidly'dried and, in this processI of drying, 'the beaters 13 playa very important part.f"Being formed with sifting.
endend-curved extensions they, not only with thebeater or upper portion, hammer the peat '.but, with the extensions thereon, lift `it to a certain extent, sift it, and convey it ltowards .the discharge bearer. 12 During all the operation, heated air regulated in volume arrdf temperature is steadily supplied.
i A By; thus in lmy improved method` of utilizing the waste or surplus heated air from the furnace inthe plant and by forcing it into,4 theopposite end of the driery to that from which the drier is fed, the results obtained in economy of fuel andextracftion of moisture fromsth'epeatcannot be over-esti mated. Y' e Y' i .With regard tothe arrangement of the driers asillustrated and described, it should againv be mentioned that one drier. may be used with most satisfactory results, but, to attain absolute satisfaction and in order to handle a large Aquantity quickly, it is preferableto use two or more driers, the operation of all being similar, and preferably, under my new method, having theheated air supplied 'from the boilers in the plant.

As many changes could be made inthe above construction and many apparently widely different embodiments of my invention'within the scope of theclaims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specifica tion and drawings shall bel interpreted as illustrative and not 1n a limiting sense.
