GEORGE H. IMMENDORF, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HENRY G. MORRIS, OF SAME PLACE.
GRAIN-DRIER.
SPECIFICATION forming part of Letters Patent No. 331,138, dated November 24:, 1885.
Application filed March 21, 1885. Serial No. 159,646. (No model.)
To all whom it may concern:
Be it known that I, GEORGE H. IMMEN- DORF, of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Driers, of which improvements the following is aspecification.
My present invention is an improvement upon that for which Letters Patent of the United States NO.-296,57 2 were granted and issued to Henry G. Morris, as my assignee, under date of April 8, 1884; and its object is to further facilitate and expedite the drying of grain or analogous solid material which is in a comparatively finelydivided condition in bulk.
To this end my improvements consist in nel, a series of radiators located in said chute,
and having alternately opposite inclined faces, mechanism for effecting the passage of a current of air through the casing and chute, a series of heatingpipes located within the casing on the supply side of the chute, a feedhopper and an agitator working therein, and an adjustable intermittently operating discharge-valve.
The improvements claimed are hereinafter fully set forth.
In the accompanying drawings, Figure l is a view in perspective of a drier embodying my invention, a portion of one side ofthe casing being broken away to show the construction more clearly; Fig. 2, an end view, partly in section; and Fig. 3, a side view, partly in section, of the same.
In the practice of my invention I provide a vertical or inclined chest or casing, A, which is preferably formed of a framing of channelbars or analogous rolled-metal supportingmembers, to which are secured sheet-metal side and end plates. The casing A, which is substantially air-tight throughout, is provided with an air-inlet near its bottom, the position of said inlet being indicated by a in Figs. 1 and 2, and with an air-discharge pipe or nozzle, a, at a point on its opposite side, said nozzleleading into a suitable exhaust-fan, D, by which a current of air is drawn through the casing. The casing is closed at top by a feed-hopper, b, having a coarsely grated or perforated bottom, I)", which forms the upper boundary of a chute or channel, B, extending longitudinally through the casing A to or nearly to the bottom thereof, and having the major portion of its sides finely grated or perforated, or formed of wire-netting of such fineness as will admit of the free passage of air without permitting the escape of the material to be dried.
A series of heater-pipes, 0, connected to a manifold, 0, near the bottom of the casing, is located therein on the side of the chute B nearest the air inlet, a circulation of steam or hot air being maintained through the heater-pipes by proper supply and discharge connections to the manifold c, for the purpose of heating theair which is drawn into the casing prior to its passage through the chute B.
The grain or other material supplied to the hopper 12 passes through the interstices in the bottom b thereof into the chute B, and in its downward traverse through the same falls successively upon and passes over the inner sides or faces of a series of horizontal radiators or drying boxes, B, arranged one above the other throughout the chute B. The radiators B, which are light hollow castings provided with ribs or projections on their faces, to increase the heating-surface thereof, are secured at their ends to the end standards of the casing A, on opposite sides alternately of the chute B, their inner sides being inclined, as shown, in alternately-opposite directions, and their outer sides forming part of the walls of the chute B intermediate between the grated or perforated portions thereof. The radiators B are connected at opposite ends alternately by couplings or return-bend pipes b inclosed by vertical coverplates 1) on the ends of the casing A, and steam or hot air is supplied to the series through a connection, b", leading into the uppermost radiator, and discharged through a nozzle, b upon the lowest of the series.
The material supplied to the feed-hopper is prevented from banking or accumulating irregularly therein by a reciprocating agitator composed of a series of plates, F, secured to a rod. or bar, f, which is fitted to slide freely in bearings in the ends of the feed-hopper, and is coupled to an arm, 9, on a horizontal rock-shaft, G, mounted in bearings on the easing A. The rock-shaft G is vibrated by a connecting-rod, h, coupled at one end to an arm, 9, on the rock shaft, and at the other to a crank, h, on a shaft, H, journaled on the easing A, and carrying a driving-pulley, h, to which power is applied from any suitable prime mover.
The discharge of the dried material from the bottom of the chute B is regulated as required by a vibrating discharge-valve, I, extending across the chute from the face of the lowest radiator to the opposite side, and provided with end journals which are mounted in hearings in the casing-standards. Movement about the axial line of its journals is imparted to the discharge-valve I by an arm, 2', which carries upon its outer end a counter-balance, i, and is coupled by a rod, '1 to a crank-pin upon a gear, 1?, secured to a short shaft which is journaled on the casing, and meshing with a pinion, i on the shaft H. The arm t and connecting-rod 2' are coupled by means of a pin, 1', on the arm,
which fits in a longitudinal slot, 45 in the connectingrod, and the degree of traverse of the valve I may be increased or diminished, or its vibration be wholly stopped, as desired, by suitable adjustments of a set-screw, t, engaging a thread in the lower end of the connecting-rod t and acting to vary the position of the pin 2' in the slot i In the operation of the drier the material acted upon is subjected in its traverse through the chute B to the action of the heated surfaces of the radiators B, and the duration of its exposure thereto is prolonged by its alternate deflection toward opposite sides of the chute by the inclined faces of the radiators. The effect of the radiators is supplemented by the current of air which, after being heated by the pipes 0, passes through the perforated portions of the sides of the chute, and, to gether with the moisture extracted from the material, is withdrawn by the fan D. The dried material delivered from the dischargevalve I falls into a car or other suitable receptacle placed below the same, or may be carried off continuously as delivered by a conveyer of any well-known type.
I am aware that driers have heretofore been constructed with grain-chutes provided with oppositely inclined shelves secured to the walls, which shelves have carried radiatorcoils for drying the grain in its downward passage,and having means for passing a current of air through the grain; and I do not therefore claim such a construction, broadly.
I claim as my invention and desire to secure by Letters Patent- 1. The combination, substantially as set forth, of a casing having air inlet and discharge passages on its opposite sides, a chute or channel having gratings or perforations in its sides and extending through said casing and separating the grain-chute from the airinlet passage on one side and the air-outlet passage on the other, a fan or blower for effecting the passage of a current of air through the casing and chute, and a series of radiators located transversely one above another in the chute.
2. The combination, substantially as set forth, of a casing having air inlet and discharge passages on its opposite sides, a chute or channel having gratings or perforations in its sides and extending through said casing and separating the grain-chute from the airinlet passage on one side and the air-outlet passage on the other, a fan or blower for effecting the passage of a current of air through the casing and chute, a series of heater-pipes locatedin the casing between the supply-opening and the chute, and a series of radiators located transversely one above another in the chute. o,
3. The combination, substantially as set forth, of a casing having air inlet and discharge passages in its opposite sides, a chute or channel having gratings orperforations in its sides and extending through said casing, a fan or blower for effecting the passage of a current of air through the casing and chute, and a series of radiators located transversely one above another in the chute,with their inner faces inclined alternately inoppositc directions and their outer faces forming portions of the side walls of the chute.
4. The combination, substantially as set forth, of acasing, a grated or perforated chute or channel extending through said casing, .a fan or blower for effecting the passage of a current of air through the casing and chute,a series of radiators or drying-boxes located transversely one above another in the chute and having their faces inclined in alternatelyopposite directions, a feed hopper located above the chute and separated therefrom by a grated or perforated bottom, and an agitator adapted to reciprocate in the feed-hopper.
5. The combination, substantially as set forth, of a casing, a grated or perforated chute or channel extending through said casing, a fan or blower for effecting the passage of a current of air through the casing and chute,a series of radiators or drying-boxes located transversely one above the other in the chute and having their faces inclined in alternatelyopposite directions, a discharge-valve journaled to vibrate in bearings below an outlet in the bottom of the chute, and an adjustable mechanism adapted to vary the traverse of the discharge-valve and admit of the discontinuance of movement of the same.
6. The combination, in a drier, of a grainchute and a series of oppositely inclined shelves, B, connected together and forming part of the walls of the chute, substantially as described.
