To all whom it may concern: ing from the essential features of the inven- Be it known that I, Enwooo B. AYRES, a citizen of the United States, residing in Philedel hie, Pennsylvania, have invented certein l mprovements in Driers, of which the following is a, specification.
One object of my invention is to rov-ide' e drier for bricks and similar materla where it, is desired to hold the moisture in the first drying chamber so as to revent the f of the outside of the brick [before the interior is dried.
A further object of the invention is to utilize the waste heat from the kiln in the drier and particularly in the final section of the drier.
These ob'ect's I attain in the following manner, re erence being had to the accompanying drawings, in which: l
Figure l is iii-diagrammatic plan view of mimproved drierig'. 2 is a side view Fig. 3 is an end view showingthe curtain raise Fig. 4 is a plan'view illustrating a. modification or the invention in which overhead circulating fans are used;
'g. 5 is a. View of the Fig. 4, and
Fig. 6 is an end view of the some.
Referring to. Figs. 1 to 3, inclusive, 1 is the casing. of the drier which maybe of any form desired and maybe in any number of sections. In thqpresent instance, I have shown it in three sections a, b and c. The several. sections can be separated by ourtains 2. which are adapted to rollers and which are lowered after the trucks are run into the driers, and the curtains can be raised when itis desired to move the trucks 8 is at central dryingchamber and 4, 4: are the heating chambers, one located at each side of the drying chamber,-and in these are coils of steam pifzes, in the .present instance, and circulating ns 6 are located in the artitions between the heating chambers and the drying chambers an are mounted on horizontal shafts 7 driven, in "the present instance, tudinal shafts 8, as clearly shown in Figs.
these fans may be modified without departdrier illustrated it across the drying;e
- jected by longi-f g. the outside so that the air in circulation is moist, hot
air. The section b is identical with the secon a, with the exception that there is. an exhaust pipe 9 in which there is an exhaust fan 10 mounted on a driven shaft ,11, driven by any suitable power. Asthe moist air circulates in the section b a certain roportion is drawn oif through the exhaust pipe 9 and the bricks, when they are ready to leo've this section, are comparatively free of moisture. They are then passed into the section a, which is the final drying chamber.
is section is not provided with heating coils but is connected to e flue 12 leading from the kiln. The flue is connected to a blower 13 which draws the waste heat from the kiln and forces it throu h the fines 14, which extend to each side 0 the drier, and communicate with the drier through the upright flues 15 which enter the chambers 16 through passages 17, and this hot air is forced chamber by the fans 18, which are moun d on horizontal shafts 19 driven by the same mechanism which drives the shaft 7. Inthe roof of the drying chamber of the section a is'an exhaust assage connecting with a flue 20. In this film is a.
- damper 21 and in the in-take fines are dam- "the gases from the hot air, or gases from the kiln, Iprovid e a; fresh air duct 23 having a. dam er 24, and this duct communicates with us from the kiln on the kiln side of the b ower,so that the' mixed with the hot air before it enters the fines 14.
By this construction, the bricks hre subto moist, heated .air in the first section of the kiln and to moist, heated air of a. lesser degree in the section 6, where a certain amount of the moist air is removed by the exhaust fan, so that the moisture is held in the bricks to prevent the bricks drying on before the interior is thorou hly dried. When. the bricks pass into the third resh air is thoroughly that, when they are delivered at the discharge end of the kiln, they are completely dried. i
The waste heat from the kiln is discharged from the kiln at about 500 degrees and the temperature isreduced by the admission of fresh air through the duct 23, as the heat in the drier is not usually over 300 degrees, and
may be much lower.
The dampers are preferably controlled by automatic damper regulators, which may be of any of the ordinary types. I
In Figs. 4:, 5, and 6,I-have shown another modification in which the same action takes place, but, in this case, the flue 14 communicates with the rear. end only of the third section a and horizontally arranged circulating fans are located above the drying chamber and these fans are mounted on vertical shafts as clearly shown, doing away with the side. chambers. There are flues 25 under the floor of the drier through which the air circulates and these flues communicate with vertical exhaust flues 26'provided 5 at the sides. Circulating fans circulate the air up through the heating chambers of the first section, down through the drying chamber in the said first section, then through a flue 28 in the floor of the structure to the sections 6', the-moist air finally exhausting through theflue 9 in the roof of the structure and in this exhaust flue is a suitable damper.
I claim: a v
1. The combination in a drier, of a series of sections, each section having a drying chamber; means for supporting the material to be dried in the chambers'of said sections; means for circulating the air in each of said sections; a flue for-conducting hot air to the last section; and a flue connecting with said A section through which the moist air escapes. 2. The combination in a brick drier, of a structure having a series of sections therein;
means for separating the sections; circulating fans for circulating air independently in the several sect1ons; heating coils in the first section for heating the air circulated therein; a final section; means for admitting preheated air t said final section; and means for exhausting the moist air from said section so that the bricks are thoroughly dried when they leave the drier.
