DRYING APPARATUS- Specification of Letters Patent.
Patented Oct. 9, 1906 Application filed November 4,1905. Serial No. 285,818.
York, have invented a new and useful Improvement in Drying Apparatus, of which the following is a specification.
This invention relates more especially to that class of driers comprising a number of superposed drying-chambers through which the material passes successivelyfrom the top to the bottom of the apparatus, the drier having means for conveying the material from the periphery toward the center in one chamber and from the center toward the periphery in the neXt, whereby the material is caused to take the longest course through the apparatus and thoroughly dried in a comparatively short time.
The objects of my invention are to simplify the construction of the conveying devices and to drive them in such manner as to relieve the parts from undue strains.
In the accompanying drawings, consisting of two sheets, Figure 1 is a sectional elevation of a drying apparatus embodying the invention, the conveying devices being omitted from the chambers below the two uppermost ones. Fig. 2 is a horizontal section in line 2 2, Fig. 1. Fig. 3 is a sim lar section in line 3 3, Fig. 1, looking upward. Fig. 4 is a fragmentary vertical section in line 4 4, Fig. 1, on an enlarged scale.
Similar letters of reference indicate corresponding parts throughout the several views.
A indicates the stationary shell or casing of the apparatus, which is imperforate and preferably of cylindrical form, as shown.
C is a heating-chamber arranged in the lower portion of the casing and containing a suitable heater, such as a gas-burner D. Above this chamber is a series of superposed drying chambers or compartments E, having perforated floors or bottoms E, through which the heat and hot air are free to pass for subjecting the grain or other material in all of the chambers to the drying action of the same. The floors or disks E are stiffened by skeleton frames or spiders F and are supported by brackets f or other suitable means.
On top of the casing is mounted a feed-hopper G, which supplies the material to be dried to the peripheral portion of the uppermost drying-chamber E and which preferably contains a feed-roller g and a rotary stirrer g to insure a uniform supply of the material to the apparatus.
In each drying-chamber is arranged a horizontal conveyor H, preferably consisting of a spiral brush which propels the material from the periphery toward the center of the chamber, or vice versa, according to the direction in which it trends, each of the dryingchambers in which the material is moved inwardly being provided with a central discharge-opening 2', while those in which the material is moved outwardly are provided with peripheral discharge-openings 1', arranged diametrically opposite each other.
Each of the conveyers is carried by a radial arm or frame J, secured to an upright shaft K, passing 1 centrally through the various chambers O E. This arm is provided with hangers 7', in the lower ends of which are mounted transverse rods or brackets 7", carrying bearings 7' in which the conveyershaft is journaled. Preferably the rods are adjustable in their hangers in a direction at right angles to the conveyer, so that the latter can be adjusted to a more or less oblique position with reference to the radial carryingarm J, if desired. To enable the bearings j to accommodate themselves to such an angular position of the conveyer, they are swiveled at their upper and lower sides in ,yokes j carried by the adjustable rods 3', as best shown in Fig. 4.
The conveyor extends from the wall of the casing to the central shaft K and is driven by suitable means from a horizontal shaft l, journaled in the hangers Z, the transmitting means shown in the drawings consisting of a sprocket-chain Z, running around sprocketwheels on said shaft and the conveyor-shaft. The shaft Zis rotated by a grooved wheel L, secured to its outer end and running upon a fixed circular track M, arranged adjacent to the inner side of the casing A. In the construction shown this track is mounted on brackets a, secured to the casing. As shown in the drawings, the sprocket-chain is arranged at or near the center of the conveyor The spiral brushes in the several chambers are arranged to trend in the proper direction: to move the material toward the discharge openings 1) 'L. The brushes, while conveying the material toward these openings, also serve by their sweeping action to remove the sweat or moisture from the kernels and keep the;
perforations of the floors or disks E open or unobstructed, permitting the free passage of the heat and hot air through the several compartments and insuring a thorough drying of the material in all of the same.
An important feature of my invention is the arrangement of the driving wheel or pulley L at the outer end of each shaft Z and of the track M adjacent to the Wall of the easing. By this arrangement the outer end of the conveyer is. not only firmly supported,
but its carrying arm J is largely relieved from strains. and the conveyer can be driven with a minimum expenditure of power.
To equalize the strain on the upright shaft K, the conveyers in adjacent drying-com-j partments are arranged on opposite sides of pable of angular adjustment relative thereto,
said shaft, as shown in Fig. 1.
In the operation of the machine the ma terial after passing through the successive v 40 chambers is finally discharged in a thoroughly dry state through a spout i at the peripheryof the lowermost drying-chamber.
The conveying action of the brushes, due to the spiral arrangement of their bristles, may
proper angle to the carrying-arms J. For
be augmented by adjusting the same at the this purpose the brushes which convey the material toward the center of the apparatus are adjusted so that their outer ends stand; in advance of their inner ends, while the brushes which convey the material toward the periphery ofthe apparatus are adjusted so that their inner ends stand in advance of their outer ends.
