O. PFEIFFER APPARATUS FOR DRYING MATERIAL Patented July 24, 1923.
UNITED STATES PATEN'lI iFFlQE.
OSWALD PFEIFFER, OF LEIPZIG, GERMANY.
APPARATUS FR DRYING MATERIAL.
Application led August 24, 1921.4 Serial No. 495,119;
- To all whom t may concern Be it known that I, OSWALD PFEIFFER, a citizen of the German Republic, residing at Leipzig, Germany, have invented certain new and useful Improvements in Apparatus for Drying =Material (for which I have filed application for patents in the following countries: in Czechoslovakia 26th June, 1920; Austria 1st July, 1920; Poland 7th July, 1920; France 9th July, 1920; Belgium 10th July, 1920; Germany 20th August, 1918)., of which the following is a specification. f f
This invention relates to a drying apparatus `for grains and similar dryingmaterial in which ho-t air is conducted through the drying material spread out upon hurdles.
It has already become known to arrange in drying apparatus of this type several superposed hurdles. The pockets which are thus formed are to be filled and emptied when the hurdles are in vertical position :and the material is dried when said hurdles are in horizontal position.
With devices of this type of known construction the revolving of the hurdles from the horizontal into the vertical position and inversely is effected in such a manner that the hurdles mounted in portable frames are carried to the places where they have to be filled or emptied. With large hurdles and heavy drying material this means very heavy work requiring many hands. T he plant requires 'further much space.
According to this invention these inconveniences are obviated by making a set coniposed of several hurdles and of an envelope for the same, revolvable around a horizontal axis. l/Vith this arrangement the hurdles can be turned 'from the horizontal into the vertical position and inversely with little power, eventually by mechanical drive. The whole plant requires little attendance and little space as the charging device can be arranged directly above the drying device and as the emptying can be eifected directly into a chute or into a conveying device arranged below the drying apparatus so that the drying material is moved through the drying device merely by the action of its natural weight` The hurdles consisting of perforated plates of sheet metal or of wire gauze are arranged in the well known manner so that always two of the plates of perforated sheet metal or wire gauze are arranged at equal distances apart, form a pocket for the reception of the drying material, the air space vbetween.v every two pockets serving for the situated at the top when the pockets have to i be-filled and at the bottom when they have to be emptied.
ln order that the invention may be clearly understood, l shall proceed to describe the same with reference to the two forms of' construction differing the one from the other merely by the arrangement of the ventilating devices, shown by way of example in the accompanying drawings.
Fig. 1 is a longitudinal section of the drying apparatus on line -y of Fig. 1.
Fig. 2 is a cross section on line m-y/ of Fig. 3 showing the drying apparatus in the position for being charged.
Fig. 3 is a similar cross section on line m-y of Fig. 2 showing the drying apparatus in the position for drying.
Fig. a shows the second form of construction in longitudinal section on line m-y of Fig. 1.
a are two oppositely situated pockets for t-he drying material formed by the perfor-ated walls ZJ.
The pockets have at one small end charg ing holes Z closed by charging doors c. The pockets a are arranged in a casing e in such a manner that they alternate with air chambers f. Ports g connect the air chambers f alternately with the chambers L and t', arranged upon the end walls of casing e so that the air which flows through the drying apparatus must always traverse one pocket filled with drying material.
In the form of construction shown by way 100 of example in Fig. 1 the ports g are closed by slides 7c adapted to be displaced in such a manner that the air is forced to flow along the path indicated by the arrows and to traverse the pockets a, alternately from above 105 and from below. i
The slides are constructed as follows: Upon a rod 7c with handle Z at the lower end three obturating slides are lixed which are of such a size that each slide can obturate 110 one of the ports g. If the rods 7c are in the positions shown in Fig. 1, air flows through ports 3 and 5 into the air channels, the other ports 8, 9, l0 being obturated by the slides g. At the left end of the casing' e (F l) the ports 5, 6, 7 are open so that the air can flow out, the ports 1l, l2 being closed. The path followed `by the air at the position of the slides shown on Fig. l is indicated by the arrows in full lines. Il the air has to -flow in the directionindicated b-y the arrows in dash lines (Fig. l) the rod 7c at the left hand end of casing o has to be pushed up.- Ward and the rod atthe right hand end has to be pulled down. The case a is revolvable around the horizontal axis y/-e and mounted upon rollers 0 and it is revolved for charging and emptying by means of a. simple driving gear y). lf each pocket a has only one charging hole the casing must be adapted to be turned oi 1800. There can however be provided charging holes at the tWo opposite sides so that it is only necessary to turn the casin e of 90. The hot air is forced into cham er z, by the air Wheel Zand it escapes from the chamber z' through tube m. The air conduits are connected with the Chambers 7L and t' by means of stuling boxes g.
In the lform oi construction-shownin Fig.
`ol' the 'drying air from said casing, and
means for turning said casing With the hurdles varound a horizontal axis.
In testimony whereof I affix my signature in presence of two Witnesses. 4
