ALPHONSE HUILLARD, OF SURESNES, NEAR PARIS, FRANCE.
Specification of Letters Patent.
Patented Oct. 24:, 1905.
Application filed September 29, 1904. Serial No. 226,544L.
1 To a whom it may concern/.
Be it known that I, ALrHoNsn HUILLARD, a citizen of the Republic of France, and a resident of Suresnes, near Paris, France, have invented a new and useful Apparatus for Quick- Drying Pasty and Liquid Materials, which apparatus is fully set forth in the following specification.
This invention relates to apparatus for quick drying of pasty and liquid materials in which the material to be dried does not come into any contact with the heating-surface and is gradually subjected to drying in the form of a very thin layer, the material being removed from the mass to be treated as it gets dried.
The apparatus chieliy consists of an endless metallic netting periodically advancing and passing through a receptacle containing the product to be dried, which gets settled on the meshes of the netting. The advance movement is imparted to the said netting by means of a series of bottom rollers, which are the driving ones, the upper rollers merely affording guidance. The whole apparatus comprised between the two series of bottom and top rollers is arranged in a heating-chamber provided with baflleplates, in which a current of hot gases circulates in the direction opposite to that of the netting, and thus gradually dries the material.
The novel feature of the apparatus forming the object of this invention consists in the use, as advancing part, of an endless fabric called helicoidal fabric-that is to say, a fabric constitutedaby metallic helical spirals screwed into each other. The separation or removal of the dried material is effected by means of a special device.
In order to make the following explanation as clear as possible, a portion of the drying apparatus, with the improvement according to this invention, is illustrated by way of eX- ample in the accompanying drawings.
Figure 1 is a plan view of a part of the endless carrier. Fig. 2 is a vertical sectional view of theapparatus. Fig. 3 is an enlarged detail of the separating device.
Referring to Fig. 2, 5 indicates a dryingchamber provided with vertical baffles 6, depending from the top of the chamber and alternating with another series of partitions projecting from the floor of the chamber, eachpartition extending only part way across the chamber, thereby dividing the dryingchamber into a series of compartments communicating alternately at top and bottom.
or is a blower for forcing air through a heating-chamber a and thence through the compartments in the drying-chamber, from which it escapes at opening 0.
Located at the top and bottom of the drying-chamber are a series of rollers 10 and 9, constituting drive and guide rollers, respectively, over which travels a belt a, moving in a direction opposite that of the air-current for carrying the material to be dried. Openings 11 12 in the floor of the drying-chamber permit the passage therethrough of the belt a, which is also supported by roller 13 outside the chamber.
14: is a reservoir for containing the material to be supplied to the belt u, asit passes through the receptacle and is guided therein by roller 15.
Z is the brushing-chamber wherein the dried material adhering to the t 'aveling belt is separated therefrom. 16 is a drive-pulley connected to pulley or drum 1 by belt 17 and imparts motion to the pulley V, which in turn actuates a pulley X, having at its center 3 a gear.
11 1's are revolublc rods or rollers, which are rotated by means of gears 18, taking their motion from pulley X, and which are for the purpose of bending the endless belt a as it passes over them and breaking off the adhering material. 1 2 is a vibrating grid located under the belt and receives a series of blows by a revoluble tappet-frame Z, the rapid blows of which discharge the remaining material from the belt.
In certain cases it is advisable to use metallic helicoidal netting. The use of this netting does not make it necessary to separate the dried material by means of brushes, with the use of which it is advantageous to dispense. This operation is effected by the addition of round rods 1 s, &c., arranged in the brushingchamber t in such manner that the helicoidal metallic netting u should be bent several times during its travel, now in one direction and now in another.
In order to prevent the rods q r s from acting as a brake, they are made continually to rotate by a small drum '0, arranged on the driving-shaft of the apparatus. This drum drives, by means of a belt, a pulley m, which, having its center in 3 drives the set of rods by means of small spur-wheels, two and two of which engage together. In the present instance the apparatus is shown with seven rods, three of them rotating in one direction and the four others in the opposite direction, thus assisting the movement of the netting or band. This bending breaks up the material suspended in the meshes. The particles which do not fall down at once are submitted to the action of a rotating parallelogram .2, which gives the netting u a vibratory movement. This netting falls four hundred times a minute on a sort of grid 1 2, and thus discharges completely all the material that had not fallen off under the influence of bending. A band a comes out from the brushing-chamber at 3 and returns to the supply-reservoir, traveling in the direction indicated by the arrow I.
I claim- 1. In apparatus for rapidly drying pasty or liquid materials, the combination of a dryingchamber, baffles therein dividing the same into compartments alternately communicating at top and bottom, an endless traveling belt for carrying said material through the compartments, means supplying the belt with material to be dried, a series of rollers in staggered relation to each other for bending said belt alternately in opposite directions to separate the dried material therefrom, and means {)or supplying a drying medium to said cham- 2. In apparatus for rapidlydrying pasty or fluid material, the combination of a dryingchamber, an endless traveling belt of helicoidal fabric carrying material to be dried through said chamber, means for supplying said belt with material to be dried, a series of rollers in staggered relation to each other for bending said belt alternately in opposite directions to separate the dried material therefrom and means for supplying a drying medium to said chamber.
3. In apparatus for rapidly drying pasty or fluid material, the combination of a dryingchamber, an endless traveling belt of heli coidal fabric carrying material to be dried through said chamber, means for supplying said belt with material to be dried, means for alternately bending said belt in opposite directions for separating the dried material from the same, and means for supplying the drying-chamber with a drying medium.
