Definitions

  • the present invention relates to a device for separating grain according to the preamble of claim 1.
  • Such a device is known for example from the magazine "Tecnica Molitoria", No. 6 of 3/30/63, pp. 133/136 and from CH-PS 587 687.
  • the two fluidized bed tables are arranged in parallel and rigidly connected to one another by a common housing.
  • a common vibratory drive induces a swirling motion that is the same in direction, amplitude and frequency. If the inclination of the fluidized bed tables and the swinging movement are optimally matched to the lower fluid bed table, disturbances in the material flow can occur on the upper fluid bed table. If the inclination of the fluidized bed tables and the throwing swing movement are optimally matched to the upper fluidized bed table, there is a risk that larger quantities of the stones will come together are carried out with the remaining granular material.
  • a similar device is shown in Japanese Patent Sho-35-13622. It has two air-permeable separating tables, which can vibrate with respect to a frame and which form a vibrating unit with a common vibrator. As stated in this publication, three different fractions are formed via corresponding outlets, but a fine and coarse fraction of admixtures (dust and sand) and only one fraction of grain material are formed. This solution could only be used in the processing of grain for the extraction of two grain fractions if there were two grain parts of different sizes in the grain, which can be separated by a pure sieving process. This rarely applies to cereals. In most cases, a light grain fraction (gravel, etc.) must be separated from the good grains. The outer grains are not very different from the other grains, but they are much lighter.
  • the so-called concentrator for example according to CH-PS 547 667
  • the light-grain reader according to CH-PS 527 002.
  • the invention has the advantage that the medium-heavy fraction can either be returned to the inlet for a repetition of the separation process and thus a further increase in the separation quality, or can be processed further as a mixed fraction in the sense of an average grain quality for animal feed production and the like.
  • two fluidized bed tables 2 and 3 are arranged vertically one above the other in a housing 1.
  • the housing 1 Between the fluidized bed tables 2 and 3 is the housing 1 with a movable wall section provided in the form of a bellows 4 so that the fluidized bed tables 2 and 3 can perform different movements relative to one another with regard to the setting of their inclinations and with regard to the setting of their throwing swinging movement.
  • the housing 1 Under the lower fluidized bed table 3, the housing 1 is provided with an air inlet opening 5, whereas, above the upper fluidized bed table 3, it has an extraction nozzle 6 which is connected to a suction air source (not shown). The air sucked out through the suction nozzle 6 enters the housing 1 through the air inlet opening 5 and flows through it successively through the lower fluidized bed table 3 and then the fluidized bed table 2 lying above it.
  • the upper fluidized bed table 2 is fixedly connected to the surrounding housing 1 and is mounted so that it can vibrate in a stationary machine stand (not shown). On the outside of the housing, the upper fluidized bed table 2 is assigned a vibratory drive 7, the direction of vibration 8 of which intersects the center of gravity of the upper fluidized bed table.
  • a material inlet 9 is arranged, which extends over the entire width of the fluidized bed table 2 and distributes the material evenly over the entire width of the table with a distribution device 9 '.
  • a light-grain outlet 10 is attached, through which puffy grains, seeds and the like emerge.
  • the upper fluidized bed table 2 is from the material inlet 9 against the Light grain outlet 10 inclined slightly sloping and adjustable in its inclination. Furthermore, the table surface of the fluidized bed table 2 is divided into two successive areas 11 and 12 in the direction of the material inlet 9 against the light grain outlet 10 (FIG. 2). In the first region 11, the diameter of the holes 13 passing through the table surface is chosen to be so small that no grains can fall through it onto the lower fluidized bed table 3. However, it is permissible for sand or dust-like admixtures of heavy parts to fall through the upper fluidized bed table 2 in the first region 11, which does not impair the separation quality but rather favors it.
  • the granular material forms a fluidized bed in which the heavy admixtures sink downwards and the light grains can rise upwards.
  • this fluidized bed flows in the mentioned layering onto the subsequent area 12, the holes 14 penetrating the table surface of which are so large that the grains can fall through them onto the lower fluidized bed table 3.
  • the second area 12 primarily the heavy admixtures fall first, then predominantly the heavy grains and finally the predominant part of the medium-heavy grains through the holes 14, whereas the light grains on the fluidized bed float against the light grain outlet 10.
  • a slot 15 is arranged between the two areas 11 and 12 transversely to the direction of flow of the wafer layer, through which the stones which are deposited in the first area 11 fall down.
  • an intermediate floor 17 is provided, which is inclined with a part 17 ′ against the stone outlet 16 is.
  • the part 17 'of the chute 17 is preferably adjustable in length so that the transfer of the heavy admixtures to the lower fluidized bed table 3 can be optimally adjusted.
  • the flaps 19 adjoin one another and form the coherent part 17 ′′ of the bond 17.
  • the length of the bottom part 17 can be adjusted in that one or more of the flaps 19 removed from the outlet 18 from the position parallel to the upper fluidized bed table 2 in FIG.
  • the grains falling down in the region 12 of the upper fluidized bed table fall, depending on the pivoting position of the flaps 19, either onto the lower fluid bed table 3 or onto the platform part 17 ".
  • they are subjected to a further separation process on the lower fluidized bed table, whereas in the second case they slide on the bottom part 17 "to the outlet 18. There they can be discharged or conveyed back to the inlet 9.
  • the lower fluidized bed table 3 is also firmly connected to the housing 1 surrounding it and is connected to the machine frame (not shown) via an oscillating bearing.
  • the oscillating bearing consists on the one hand of coil springs 21 and on the other hand of a length-adjustable articulated lever 22 which is connected via the joints 23 and 24 to the housing 1 on the one hand and the machine frame on the other.
  • the inclination of the lower fluidized bed table 3 can be adjusted by adjusting the length of the articulated lever 22.
  • On the housing 1 is the lower one Fluidized bed table 3 associated oscillating drive 25 is arranged, the oscillation direction 26 is adjustable such that it intersects the center of gravity of the lower fluidized bed table 3.
  • the oscillation drive 25 can be displaced relative to the fluidized bed table 3 such that the angle enclosed by the oscillation direction 26 with the plane of the fluidized bed table 3 can be adjusted in order to optimize the separation quality on the lower fluidized bed table 3.
  • the table surface of the lower fluidized bed table 3 is formed by a perforated plate, a mesh or the like. The perforation is so small that the granular material and the heavy admixtures (apart from a possible heavy dust content) cannot fall through.
  • the lower fluidized bed table 3 opens into the stone outlet 16, whereas the heavy-grain outlet 27 adjoins its opposite end.
  • the granular material passing through the upper fluidized bed table 2 and striking the lower fluidized bed table 3 is then put back into a fluidized bed in which the heavy admixtures settle down and over which the heavy grains are arranged in accordance with the lower floating speed.
  • the latter float, due to the inclination of the fluidized bed table 3, against the heavy grain outlet 27, whereas the heavy admixtures are transported against the stone outlet 16 under the effect of the throwing motion of the oscillating drive 25 and are discharged there.
  • each throttle valve 31 which extends across the width of the housing 1 and is rotatably mounted in the housing 1 with stub axles at the ends. With outside the housing to the S tommelachsen placed knobs each throttle can be pivoted in any desired rotational position 31st
  • the width of each throttle valve 31 corresponds to the width of a chamber 30, so that the air flow through a chamber 30 can be completely blocked or completely released.
  • a uniform passage of air through the upper fluidized bed table 2 can be forced.
  • This can advantageously be achieved in that the distance between the underside of the transverse walls 29 and the table surface of the upper fluidized bed table is at least 1.5 cm, preferably approximately 2 cm. So that the device can be designed with a low overall height without the control of the air passage through the upper fluidized bed table influencing the air passage through the lower fluidized bed table 3, the distance between the underside of the transverse walls 29 to the table surface of the upper fluidized bed table is approximately 1/10, but at most 1/3 of the average distance between the two table surfaces of fluidized bed tables 2 and 3.
  • side walls 33 are pivotable in the second region 12 about pivot axes 32, with which the effective surface of the second region 12 can be reduced correspondingly to the decrease in the fluidized bed volume.
  • These side walls 33 can be adjusted by spindles (not shown) that can be actuated from outside the housing 1.
  • the setup described works as follows.
  • the granular material with the heavy admixtures is fed through the inlet 9 onto the upper fluidized bed table 2 and evenly distributed thereon by the distribution device 9 '.
  • this is induced in the direction of flow by the oscillating drive 7, which is effective in the direction of flow.
  • the two fluidized bed tables 2 and 3 are penetrated vertically by an air stream.
  • the granular material which spreads out on the upper fluidized bed table 2 forms a fluidized bed, a uniform passage of air being forced by adjusting the throttle valves 31 in the upper fluidized bed table 2.
  • an undisturbed fluidized bed is formed, in which the heavy admixtures and the granular material can be stacked on top of each other according to their floating speed.
  • the fluidized bed reaches the slot 15, the width of which is dimensioned such that both the heavy admixtures and the granular material can pass through, the heavy admixtures and heavy grains lying in the bottom of the fluidized bed fall through the slot 15 onto the inclined bottom part 17 ' .
  • the light grains not falling through the second area 12 flow to the light grain outlet, whereas the grains falling onto the bottom part 17 "pass through the outlet 18 are led away, of the heavy grains and heavy admixtures falling on the lower fluidized bed table 3, the major part falls on the eode part 17 'and is thrown by this near the stone outlet 16 onto the lower fluidized bed table 3.
  • the lower fluidized bed table forms again a fluidized bed in which the heavy admixtures sink down and are conveyed under the effect of the throwing swinging movement to the stone outlet 16. In contrast, the grains lying above swim against the heavy grain outlet 27 and are discharged there.
  • the quality of the separation work on the lower fluidized bed table 3 becomes you Optimized by adjusting the inclination on the articulated lever 22 and by adjusting the swinging motion according to the inclination, frequency and amplitude.
  • Fig. 3 are on the the lower fluidized bed table undergo further processing of those grains and admixtures which fall down in areas A, B and a and b through the upper fluidized bed table 2.
  • the light grains D or medium-heavy grains C occurring through the outlets 10 and 18 are discharged or, if necessary, brought back to the inlet 9.
  • a threshold 34 can connect to the slot 15 on the upper fluidized bed table in the flow direction of the fluidized bed. This forces the heavy parts that settle in the first region 11 down through the slot 15 onto the bottom part 17 'or from there onto the lower fluidized bed table 3.
  • the attachment of the threshold 34 is indicated when the separating device has a high throughput without loss the quality of the cutting work is required.
  • the slot 15 between the two regions 11 and 12 can be omitted if the throughput required by the separating device is relatively low. Under this condition, the elimination of the slot 15 does not reduce the quality of the separation work.
  • the quality of the separation work can also be influenced by the fact that the pod part 17 ′′ can be displaced away from the slot 15 in the direction toward the light grain outlet 10 and can be locked in any position.
  • the displaced position of the bottom part 17 ' determines how much of that through the heavy grains or heavy admixtures that pass through the bottom part 179 of the second region 12 of the upper fluidized bed table 2 and are to be guided by this against the stone outlet 16.
  • This adjustability of the pod part 17 ' is advantageous if the separating device alternately requires larger or smaller throughputs while maintaining the quality of the separating work, or if there are qualitative and / or quantitative differences in the heavy admixtures during different processing campaigns in the granular material.
  • the slot 5 need not be a continuous opening. It is sufficient if a zone of comparatively coarse perforation is arranged in the area of the slot 15.
  • both the slot 15 and the part 17 "of the base 17 are missing.
  • a pre-coating channel 35 is delimited on the lower fluidized bed table 3 by two parallel walls 36, into which the through the upper fluidized bed table 2 material falling therethrough is passed through two baffles 37.

  • the length of the pre-stratification channel 35 is preferably chosen to be so large that in the fluidized bed flowing into it up to the channel mouth, this stratification is largely carried out according to the floating speed, so that this pre-stratified fluidized bed in this stratification can pass unchanged onto the rest of the table surface of the fluidized bed 3.
  • the lighter grains thereby learn a deflection by 180 0 in the sense of the arrows, the heavy impurities whereas under the effect of casting movement in a substantially straight line further towards the stone outlet 16 are conveyed.
  • the grains floating on the lower fluidized bed table 3 and freed from the heavy admixtures enter the heavy grain outlet 27.
  • the lower fluidized bed table 3 can be delimited from the heavy grain outlet 27 by a retention threshold (not shown) which prevents heavy admixtures from being carried away by the heavy grains.
