Definitions
- the present invention relates to a device for Separate flowable bulk goods, especially grain of all kinds for the milling industry and in the field of seed processing.
- Trief cylinder For cleaning and sorting bulk goods are already Trief cylinder known.
- Such drive cylinders consist in essentially of a hollow cylindrical body, on the Inner wall of pocket-shaped recesses, so-called Cells, as well as from a screw conveyor load-bearing medium wave by an upwardly open collecting trough is surrounded.
- a drive cylinder For separating bulk goods by means of a drive cylinder, the latter is brought into the cylinder filled and the cylinder rotates around its own longitudinal axis transferred.
- the cells in the inner wall of the drive cylinder with all those bulk material elements that fit into the cells due to their geometry. All not in the cell-fitting bulk material elements remain in the lower one Area of the drive cylinder back. Has the drive cylinder rotated by a certain angle, so fall the bulk elements taken from the individual cells out and get into the mentioned trough. Consequently can take two bulk material flows from the drive cylinder are determined in each case with regard to the geometry Bulk elements included.
- disk trieurs are known in which several ring disks sitting on a shaft, in both sides pocket-shaped depressions (cells) for receiving individual bulk elements are present during their Partial rotation into the bulk material to be separated intervene that fit into the cells of the washers Take the bulk material elements out of the bulk material and then move on Rotation by a certain angle this entrained Eject bulk goods into forwarding gutters. Because of the large number of washers, which are axially one behind the other can be arranged on the shaft with disc drives a relatively large mass throughput comparatively small construction volume. Not from them Ring disks of the disk trier grasped bulk material elements gradually migrate to an overflow at the outlet end of the Disk Trieurs and can be removed there.
- Disk packs have different cell sizes from one another, for example, the window interior two disc packs a total of three bulk fractions are taken, which after certain particle geometries are sorted.
- the existing interior systems have the disadvantage that the mass flow of bulk material to be enforced through the claim is limited after a small construction volume.
- the presorting drive cylinder is the weakest link in the Chain of an engine cylinder system.
- a Device for separating flowable bulk materials create one with the largest possible mass throughput has the smallest possible construction volume and the one improved degree of cleaning and sorting accuracy.
- the existing Plants provided for pre-sorting drive cylinders to replace a pane interior.
- This pane interior then feeds at least one downstream round grain cylinder for separating the round grain from the bulk material and at least one long grain drive cylinder for separation the long grain from the bulk material.
- the individual Cell-bearing ring disks of the disk drive on its Shaft can be arranged relatively closely spaced a large number of cells in a relatively small space accommodate.
- a circular conveyor that is arranged below the disc mechanism, as special proven advantageous. Because on the circular conveyor at the same time several pre-fractions are given up and handed over , it enables a particularly space-saving design.
- the round conveyor has one in a horizontal plane circumferential path below the disc drive, e.g. a gutter, on the sections of which the individual pre-fractions be transported.
- the number of available Sections on the path between the drop-off and drop-off points A pre-fraction determines the number of the round conveyor transportable pre-fractions.
- Another advantage of the circular conveyor consists of the fact that it works according to type, i.e. without any residues when changing fruit or variety.
- Another measure to ensure variety purity consists of a screw conveyor in the bottom of the disc mechanism to arrange that for that located in the window interior Bulk material is accessible from above and during the Operation of the disc drive is at a standstill. Should be the type of separating bulk goods can be changed, so the Screw conveyor all in the bottom area of the disc drive remains of the previously separated bulk material from the Promote window interior.
- the attachment consists essentially of the pane interior 12, the Round conveyor 13, the runk grain cylinder 10, the long grain cylinder 11 and the round grain refill cylinder 14.
- the Conveying screw 32 In the bottom area of the disk drive 12 is the Conveying screw 32 with the axis of rotation 33.
- section I is the pre-sorting device through which the conveyed the entire mass flow of the grain to be separated must be shown in the form of the disc drive 12.
- the opening 24 gets the grain into the interior of the Disk Trieurs 12, where the disk packages 16 and 17 supporting shaft 15 is mounted.
- an aspiration opening At the opening 34 in the Pane interior 12 is an aspiration opening, to which a suction device is connected upstream of a filter to remove the grain dust and to produce a slight negative pressure can be connected.
- the Wave 15 is from storage in the housing of the Disk Trieurs 12 releasable so that they together with the Disk packs 16 and 17 removed from the disk interior 12 can be.
- the with their plane of extension perpendicular to Shaft 15 and axially spaced apart Individual disks of the disk drive have a diameter from 800 mm.
- the first disk package 16 comprises a total of 36 disks.
- the bulk material is rotated the first prefraction 18 removed from the shaft 15.
- the disk package 17 comprises a total of 24 disks with one 9.5 mm cell size. With the help of the disk package 17 is the bulk material when the shaft 15 rotates, a second pre-fraction 19 removable, the essentially larger break than the pre-fraction contains 18 as well as large grains.
- Section II the one folded into the drawing plane by 90 ° Rotary conveyor 13 can be seen. He has the two task areas 25 and 26 and the two delivery areas 27 and 28 on.
- the circular conveyor comes e.g. a sponsor in question who consists of a closed circumferential channel in which the Traction means in the form of a chain or a steel cable, on the or almost in terms of area and shape Shovels with trough cross-section hanging, running.
- the Task areas 25 and 26 of the rotary conveyor 13 stand out characterized in that the channel is open at the top and thus the Pre-fractions 18 and 19 by gravity in the same can reach. There they are then mentioned by the Buckets transported to the discharge areas 27 and 28 where finally the gutter through funnel-shaped openings left again by gravity.
- the first pre-fraction arrives 18 with a mass flow of 12,600 kg / h into the task area 25 and the second pre-fraction 19 with one Mass flow of 8400 kg / h in the feed area 26.
- Round conveyor 13 it is also possible to use the Round conveyor 13 to convey. All you have to do is length the sections of the path of the circular conveyor 13 between the the respective task area and the associated delivery area be shortened.
- the horizontal conveyance of the disk packs 16 and 17 pre-fractions 18 and 19 obtained from the grain has a particularly advantageous effect on the overall height of the entire Device made by using the circular conveyor 13th can be significantly reduced.
- the round grain cylinder 10 shown in section III After the first pre-fraction 18 in the delivery area 27 of the Round conveyor 13 has reached, it falls through a down pipe the round grain cylinder 10 shown in section III.
- This Rundkorntrieurzylinder 10 has the task of all breaking and Foreign grain fractions from the first pre-fraction 18 separate.
- the cell size used in the Cells located inside the cylinder is preferably 4 to 5 mm.
- the second pre-fraction 19 becomes after reaching the delivery area 28 of the round conveyor 13 also through a downpipe the round grain reading cylinder 14 shown in section IV fed.
- the collecting trough of this round grain reading cylinder 14 can then the bulk material portion 4, namely any broken grain and small weeds, removed become.
- the cell size of the Round Grain Reading Cylinder 14 is preferably 4.75 mm to 5.0 mm.
- the third pre-fraction which has a mass flow of 3000 kg / h 20 is not conveyed further via the round conveyor 13, but by gravity through the Down pipe 22 (see FIG. 3) in the long grain drive cylinder 11.
- the cell size of this drive cylinder is preferably 10.5 mm so that all good grains fit into these cells and carried into the drain pan of the drive cylinder become.
- the foreign grain fraction 3, e.g. thick oats, barley and other large long admixtures, in the long grain cylinder 11 is thus directly from the lower area of the cylinder removable.
- the speed of the round grain drive cylinder 10, the round grain reading cylinder 14 and that of the long grain cylinder 11 are preferably 39 rpm.
- the shaft 15 of the Disk Trieurs 12 preferably rotates at a speed in Range from 35 rpm to 45 rpm.
- Fig. 2 is the circuit of the individual drive cylinders as well as the disc drive in analogy to an electrical one Circuit shown. This corresponds to the pane interior total bulk current I supplied to the electrical Current.
- the short grain drive cylinder 10, the short grain refill cylinder 14 and the long grain drive cylinder 11 are parallel to each other and in their entirety of the disc drive behind the latter connected in series.
- the the window interior 12 downstream drive cylinders must are not necessarily connected in parallel, but can also in combinations of parallel and series connections to be ordered.
- FIGs 3 and 4 is a structural design Device according to the invention for separating grain shown. It is in particular the spatial location of the essential components of the device to each other detect.
- the entire device is in the frame 23 housed in the top area a little off center the pane interior 12 is arranged to the rear. Under the pane interior 12 is the horizontal arranged round conveyor 13. Below that is the round grain cylinder 10 recognizable. Disc interior 12, round conveyor 13 and Rundkorntrieurzylinder 10 extend over the entire length of the frame 23 and have substantially the same length dimension.
- Below the round grain cylinder 10 are the round grain reading cylinder 14 and the long grain drive cylinder 11 are arranged.
- the longitudinal axes of the last two drive cylinders are located doing it on a straight line.
- the individual funnel-shaped outlets 31 in the lower region of the Detect device The shown in Figures 3 and 4 circled digits correspond to those of the bulk solids from Fig. 1.
