To all/whom t may concern:
Be it known that I, GUIDO E. LOB, a citizen of the United States, and residing4 at Chicago, inthe county of Cook and State ot' Illinois, have \invented a new' and useful Improvement in Pneumatic Conveyers, ot
which the follov'vfingv is a completaspeciication. v v
This invention relatesto improvements in pneumatic conveyrs,'and more particularly -to a pneumatic conveyer adapted to, handle 'lmaft and other grain.
Heretoiore it has been customary to'conduct the germinated or growing grain, commonly known as 'green malt from the Ventilating tanks to the kiln room by means or" mechanical' conveyers, such as cup, screw orl belt conveyers, and wherever such systems are employed there is always a greater or less amount otmaltleft .in'theconveyer troughs after each batchof grain is handled. A considerable portion of the malt thus left has been mashed in the conveyer and adheres to the belt or screw and to the trough. The malt thus left, which contains a large percentage of moisture, invariably sours. or 'molds land if 'not thoroughly cleaned from the troughs before the next batch is run through it tends to injure the entire batch. Furthermore such conveyers do not get proper ventilation, and owing to the moisture in the grain they tend to become sour or musty it properV attention is not given them, With-the result that a large percentage of samples analyzed in the laboratory show traces of' mold.
The objects of this invention are to provide a pneumatic conveyer adapted particularly for carrying-wet or damp malt or become soured other grains, and which is so constructed that the grain cannot lodge therein and to lprovide a yconveyer adaptedto be kept. in a thoroughly dry condition so as not to contaminate the malt; and to provide a conveyor of cheap and simple construction adapted to rapidly convoy thc malt to a place of deposit with a minimum amount ol' wear on the opor-ating A specific construction embmlying said invention is illustrated in the accompanying drawings,`in which: t
1F igure l is 'a fragmentary, plan view of a conveying system embodying this inveiition. lhgl 2 is a section takenon line A-A of Fig. 1. Fig. 3 is an enlarged side elevation of one of the conveying pipes and air mains with their connections. Fig. 4 is a fragmentary,` longitudinal section of the conveyer pipe with a modified form of injector.`
In the construction shown in said drawings, the Ventilating drums 1 arev supported upon suitable foundations 4or supports 2, and each 1s provided with an outlet gate or 4door 3 in the fbottom for the malt. As
'shownthere are two batteries of said drums though any desired number may be emlyed- 'A blower. 4 of any preferred construction has, an air main or pipe 5 leading from the exhaust port thereof and is provided with "branch, mains 6 leading to the ditl'erent batteries, and which preferably extend beneath the drums 1 and are closed at their forward ends. A conveyer pipe 7 also extends beneath the drums of each battery and is parallel with the air main 6. Said pipes and mains are supported, one above the other, uponV brackets or standards 8 which extend above the pipes, andthe rear end'of each 'conveyer pipe 7 is connected with the adjacent air main 6 by means of a pipe connection 9, which extends upwardly and forwardly from the main 6 at an angie of approximately l5 degrees, and is provided with-a gate valve 10 by means of soV which the passage of -air from the main 6 into the forward end of the conveyer pipe 7 l when not'jn use, by means to tit closely in malt.
forwardly at an angle of approximately 4:5 degrees. An air lfeed pipe 15 leads forwardly from the air main 6 and opens into the pocket 13', and the air blast conducted therethrough and through the pocket into the ipe 7 is directed forwardly of said pipe 7. i Agrain receiving spout or pipe 16 opens into the body 12 preferably at a point rearwardly of the pocket 13 and at a forwardly directed angle to the pipe 7. The outer end of said spout 16 is adapted to be closed,`
of a lid 17 which is hinged on an ear or bracket 18 carried on the body 12, and a spring 19 one end to said lid and at its other end to Ithe body forwardly of said ear and acts normally to hold the lid closed.
Carried on the tops of the brackets or standards 8 are the track rails 20 which extend parallel with the conveyer pipe 7. Mounted to travel onvsaid track is the hopper 21, the outlet spout of which is adapted i the receiving spouts 1G and to'deliver malt or other grain thereto from the drums.
In the construction shown in Fig. 4, the conveyer pipe 7 is provided with an adjustable injector by means of which the amount and force of the air entering the conveyer pipe may be regulated. Said injector comprises a body 22, having a threaded .portion 23 on which .is adjustably secured the conical pocket 2-t, which surrounds the inner end of said body. By adjusting said pocket longitudinally of the body the space l25 bet-Ween the end 26 of said body and the sides of said vpocket is ,restricted or enlarged to regulate the passage of air, Vith of the injector and the air enters through pipe 27 which opens into said pocket.
The operationA of the const .ction shown is as follows: The hopper is set beneath the drum from which it is desired to take The lid of the adjacent receiving spout 16 is opened and the hopper is connected in said receiving spout. The lids of the other receiving spouts remain closed. Air is then forced through the air niain 6 and it enters the injectors forwardly of the receiving spouts. vThe forward travel of the air 'tends to create a vacuum at the rear of each injector and thereby acts to suck the malt -froni the veying pipe and carry it forwardly therethrough to the p lace of deposit. The air from each injector also acts to drive the malt ahead of it pipe. If desired to also apply air at the rear of the malt received in` the first injector the`gate valve 10 may be openedto permit air to pass from the main in`to' the rear'end of the hopper into the -conis attached atthisconstruction the grain enters the conveyer pipe at anyv point back forwardly through the pipe 7C Owing' to the 'for-- -be used for each pipe,
ing into said pocket, and a iend to the air pipe and nected at one end to air pipe, ing into wardly inclined openings 'from the pockets 13 to the bodies 12 the ina-lt cannot l lodge in the conveyer and thezconveyer will be thoroughly cleared of maltl and dried= by the air blast, thereby keeping it sweet and' cleai'i.
Obviously more than one hopper may battery of drums if desired so that malt may be simultaneously conveyed from several drums, and obviously also many details of the construction and arrangement may be varied without departing i rom the scope of this invention.
I claim:
1. A pneumatic conveyer comprising an air pipe, meais for forcinfrair through sai pipe, a conveying pipe parallel Witlrsaid aii` nipe, ea h pine having a section therein,\and
each section having a branch opening` at an angle therefrom, said branches being ponnected together to form alcontinuous` connection between the two pipes, a conical pocket 'surrounding and extending beyond the end of one of said sections and into which said connection 'opens, said pocket being adapted to' conver e tl'e air current from all points circuin eren'ially of the section, a receiving spout opening into the section at the rea-r of the pocket, a bracket on said section, a cover hinged to the bracket and adapted to close the spout, and a spring acting normally to hold the cover in closed position.
