Definitions
- Title Device and method for reading out heavy goods, in particular stones or the like, from grain and other bulk materials .
- the invention relates to a device and a method for reading out heavy goods, in particular stones or the like, from grain and other bulk goods, by means of two superimposed, inclined swing tables, through which the same air flows and which has a common drive, the lower swing table being designed as a stone reading table is.
- the actual grain is obtained with a third-party stock, which consists in particular of small stones, glass fragments and metal parts and of various light stockings (such as large bowls parts, fragments of stalks and foreign seeds), all of which lie in a certain grain size range, for example in the case of wheat varieties in the range from 2 mm to 6 mm or in the case of corn in the range between 5 mm and 20 mm.
- the light components are separated by special read tables (such as paddy readers or light grain readers).
- the separation quality in this known device is very good and is not significantly impaired in practice even in the event of minor disturbances, such as fluctuations in the air speed or the like, and in the event of instantaneous power fluctuations.
- minor disturbances such as fluctuations in the air speed or the like
- instantaneous power fluctuations within the same device only the function of separating heavy constituents from a regularly much larger mass of other grain material is achieved, the throughput of a machine not being able to be increased arbitrarily upwards. It has been shown that from a certain size of the surface of the read-out table, perfect work performance is no longer guaranteed at any point on the read-out table, since accidental disturbances result in product accumulations and heavy parts in the product stream can also be carried away.
- Another known device (DE-A-3.148.475) enables very high qualitative requirements to be achieved, not only the reading out of stones or the like, but also the division of the grain material into individual fractions (such as heavy grain and Light grain) is possible. A very good • separation of heavy and light grain as well as an almost complete stone selection is achieved in the course of a single machine pass.
- it is necessary in the known device to carry out each individual working section under optimal conditions which, however, means a very considerable structural outlay (for example the use of a suction hood with bulkhead-like subdivision, with each space having an individually adjustable air ⁇ throttle is assigned).
- the structural effort (and thus also the price) of this previously known device is so great that the use of the device is thereby limited.
- this device has also shown that, similar to DE-C-1.913.708, only a limited increase in the product throughput is possible, because if the throughput rates are too high, the precise guidance of the fluidized bed by controlling the local air quantities is no longer sufficiently good and the desired stratification can no longer be achieved to the desired extent.
- a device of the type mentioned is known from CH-A-587.687.
- the upper vibrating table is designed as a sieve table and provided with three sieves of different mesh sizes, while the lower vibrating table is only air-permeable, but not product-permeable.
- Both swing tables are held in an inclined position by a common frame and are driven by an imbalance controller with a throwing swing movement in the direction of the higher table ends. The bulk material to be sorted is fed into the device at the upper end of the upper table.
- the air flow and the throwing-swinging movement create a stratification during the flow of the bulk material along the upper vibrating table in such a way that the heavy components of the bulk material are concentrated in a lower layer lying directly on the table. Depending on their size, the heavy components eventually fall through the corresponding perforations in the screen grille.
- the finest sieve is arranged in the area of the inlet so that the smallest parts of the heavy goods can fall through first. This is followed by a sieve with a medium and finally one with a coarse mesh.
- Vibration table can be influenced.
- the lower vibrating table is designed as a stone reader, which is why all parts which are not lifted by the air are conveyed and carried upwards in the direction of the outlet for stones in accordance with its throwing-oscillating movement.
- the light grain swims like a liquid carried by the air flow above the layer enriched with heavy goods towards the lower product outlets. In practice it has been shown that with this known device neither a particularly large degree of readout (percentage of stones read out) nor a sufficient selectivity when dividing the grain material into a light and a heavy fraction can be achieved.
- the invention is based on the object of developing a simply constructed stone reader which works particularly economically with excellent cutting performance and in which the throughput in particular is particularly large compared to the area of the vibrating tables.
- the upper vibrating table is designed continuously as a shift table and only at its lower end a short area for the diarrhea of the layer enriched with heavy goods and a device for dropping the diarrhea onto the lower vibrating table has, wherein the discharge is directed towards a central region of the lower vibrating table or takes place.
- the device according to the invention produces very excellent results with regard to the achievable selectivity of the individual fractions, plus a very good readout level and works with a previously unknown level of economy.
- the device according to the invention it is possible, compared to previously known devices, to work with a significantly increased throughput capacity (or with a given sieving performance with significantly lower air expenditure) compared to previously known devices, which results in a previously unknown level of economy when using this device.
- the device has a relatively simple, uncomplicated structure, which also enables inexpensive manufacture.
- the upper vibrating table is used according to the invention over its entire length for the formation of shocks and only at its end within a short range, the whole is particularly preferably less than a fifth of the length of the upper vibrating table, the layer enriched with heavy material is released onto a central region of the stone reader located below it.
- the "middle area" is considered to be an area which is in a middle position with regard to the longitudinal extent of the lower vibrating table, that is to say at each of its two ends a further table area adjoins the end of the table in question.
- This central region of the lower oscillating table preferably comprises the region which, in the case of the lower oscillating table, if it is divided into three regions of approximately equal size in its longitudinal extent, makes up the region of the middle third which arises in the process.
- the measures according to the invention create particularly happy framework conditions for a favorable product flow. What is essential here is the flawless formation of the layering on the upper layer table, which is ensured precisely by the fact that the upper layer table is not permeable to the product over a particularly long length, so that there is good layering over this relatively large length of the upper vibrating table can build up undisturbed.
- This short range for the diarrhea ie the diarrhea zone arranged at the end of the upper table, is preferably at most one fifth of the total length of the upper vibrating table.
- this layer regularly contains 100% of the stones artificially added during the experiment, and thereby on the below, as Stone readers trained swing table are placed in an almost optimal location. This makes it much easier to read out the lower vibrating table (stone reader), since the lightest fraction no longer falls and the separation on the stone reader no longer interferes.
- the discharge via which the diarrhea occurs from the short area of the diarrhea zone to the lower oscillating table is designed as a slide which ends at a distance above the lower oscillating table. It is particularly preferred that the slide is arranged inclined in the opposite direction to the inclination of the vibrating tables.
- a further, very particularly advantageous embodiment of the device according to the invention also consists in the fact that the upper end of the upper
- Ventilated shift table and a guide cover plate which with
- the fluidized bed or the lower product layer migrating upwards on the table support is stopped.
- the air sucked through the surface in this area acts as an air jet against further upward migration of the goods. If the air speed is set correctly, it can be achieved that stones, glass fragments and metal parts can move just up to the uppermost point of the outlet for the stones due to the kinetic energy of the throwing vibration.
- the slide is preferably made air-impermeable and ends approximately at an intermediate height between the lower and the upper vibrating table.
- a layer separating knife is attached to the lower end of the upper vibrating table .
- the short area for the diarrhea at the upper vibrating table is preferably designed such that it has passage openings with a diameter which is a multiple of the average grain size of the heavy goods.
- Optimal functioning of the upper vibrating table is also favored by the fact that it is finely perforated and has a smooth surface.
- a strong inhibiting effect is achieved for the product layer lying directly on the upper vibrating table, as a result of which all heavy parts that have once entered the layer below which is prevented from flowing away quickly, neither by the air nor by the Vibration movement can be returned to the upper layer.
- the effect of the formation of an overlying layer is particularly favored, so that both the amount of air required and the vibration energy can be optimally used. From this, however, the advantage of maximum utilization of the vibrating table area in the sense of a substantially greater throughput capacity for a given area can again be achieved.
- the lower vibrating table is provided with a good support which has an air-permeable, fine mesh, a perforated plate in parallel and at a distance below it, and, between the two, a bulkhead-like structure (sandwich structure) such that that the lower vibrating table has an approximately constant air resistance over the entire crop support and is independent of the crop layer thickness resting on it.
- the lower vibrating table is also particularly preferably provided with a rough surface, which favors the fact that the heavy parts are conveyed for the heavy parts due to the throwing-swinging movement after the higher outlet.
- an outlet channel for the good repulsion of this vibrating table is arranged at the end of the upper vibrating table, which opens into an opening of the good outlet for repelling the lower vibrating table, again, preferably, an adjustable one in the outlet channel of the upper vibrating table
- a flap is arranged for optional mixing of the push-off of the upper vibrating table with the push-off of the lower vibrating table or for separate removal of both push-offs.
- the upper vibrating table is designed to be air-permeable in the area of the product inlet, which already favors the formation of layers in the area of the product inlet.
- the largest possible surface spread for the product is achieved on the upper and on the lower vibrating table, this however, in such a way that the entire available work surface is supplied with product in a fairly uniform manner and an almost identical work process can occur at any point across the flow direction of the product.
- This workflow is progressively and consistently continued from the beginning of the product entry onto the respective vibrating table surface to the point at which the corresponding work stage has been completed.
- the product is transferred from the beginning of the table and over its entire width into a uniform layering and this is consistently developed to the lower end of the same table.
- the device according to the invention therefore basically has two inclined, air-permeable vibrating tables, one on top of the other, the lower one of which can be set into a swinging oscillating motion by means of an unbalance exciter with a throwing component directed towards its upper end and both of which are penetrated by the same air flow.
- the inlet for the material to be treated is located at the upper end of the upper vibrating table, the upper vibrating table having two areas over its length, in the first area directly adjoining the inlet it is only air-permeable, while in the here subsequent second area is also product-permeable.
- Some of the falling through material reaches the bottom - I I- vibrating table, which in turn has a heavy goods outlet at its upper end and a light goods outlet at its lower end.
- the well-permeable second area of the upper vibrating table is very short in comparison to its first only air-permeable area, and all of the material falling through the second area is completely applied to the central area of the lower vibrating table, the upper and lower vibrating tables having the same oscillating movement To run.
- the invention further relates to a method for reading out heavy goods, in particular stones, from a stream of goods, e.g. Grain or the like, via two oscillating tables inclined towards product outlets, through which the same air flows and which together causes them to oscillate, both of which are impressed with a swinging oscillating movement in the direction of the higher end of the respective oscillating table, the upper oscillating table being the good layers and the lower vibrating table the heavy goods, e.g. reads the stones or the like.
- the method according to the invention is characterized in that the material is layered on the upper vibrating table over its entire length and at its lower end a portion of 20% to 80% (weight%) of the material flow, in which almost all of the heavy material is located, deducted and thrown as a supply to a middle area of the lower vibrating table like a veil.
- the method according to the invention places the function of stone selection in the foreground, but also enables a second function, namely that of light grain selection, and all in a surprisingly simple and economical way.
- the method according to the invention ensures that only the part of the total material flow in which the heavy components are located is thrown onto the lower stone reading table, the light component fraction being already drawn off at the upper vibrating table and no longer being thrown down .
- only a portion of the total crop flow namely 20 to 80 (% by weight)%, is thus transferred to the lower table forming the stone reader, since in the remaining portion of the crop stream which is already at the bottom End of the upper table is discharged as a light grain fraction, no heavy parts are included.
- the lower vibrating table therefore no longer has to process and process the entire product throughput, but only the corresponding product throughput that is transferred to it, which results in a noticeable relief of the stone reading table.
- a stratification takes place again on the lower oscillating table, which, however, can then only be carried out with the lower, namely the portion of the original material flow thrown downwards. Since a product stream with a relatively large proportion of heavy constituents is thrown onto the lower vibrating table, the relatively " light parts" are also very quickly transferred to a layer that forms above the heavier parts and floats to the lower end of the lower table, and thus relatively quickly to the grain outlet.
- an air jet directed toward the other end of this vibrating table is preferably generated directly above the table surface to limit the fluidized bed formed on the lower vibrating table.
- the supply of goods to the lower vibrating table is very particularly preferably deflected by means of a slide in a direction opposite to the flow direction of the material on the upper vibrating table and is thus thrown onto the lower vibrating table. This also results in additional loosening of the material. It is again advantageous if air is continuously passed through the two vibrating tables and is deflected in the area of the slide in a direction opposite to the transport movement of the goods occurring there.
- the grain is fed in at the upper end of an inclined first air-flowing oscillating table, is guided along this along a flow path and is stratified in an upper light layer and a layer arranged underneath and enriched with heavy goods.
- the layer enriched with heavy goods is thrown off the first vibrating table and partially placed on a second inclined air-flow vibrating table, transferred there into a fluidized bed and the heavy goods or the residual fraction freed from the heavy goods are drawn off at both ends of the second vibrating table.
- the entire layer enriched with heavy goods is drawn off and completely dropped onto a central area of the second vibrating table.
- FIG. 1 shows a schematic longitudinal section through a device according to the invention
- Figure 2 shows the device according to the invention already shown in principle in Figure 1 with further structural details, also in principle;
- FIG. 3 shows a section through the sandwich construction of the lower vibrating table (stone reading table) of the device according to the invention shown in FIGS. 1 and 2;
- Figure 4 is a detailed top view (with a partial section) of the Dar ⁇ position of Figure 3, and
- FIG. 5 shows another embodiment for a device according to the invention as shown in FIG. 2.
- the device shown in FIG. 1 has a lower vibrating table 1, which is designed as a stone reading table, an upper vibrating table 2 designed as a layered table, and a housing 3 which laterally and above delimits both vibrating tables.
- the stone reading table 1 is open at the bottom; the air sucked in freely from the surroundings through the stone reading table 1 is drawn off by the layer table 2 and by a fan 4, which is only symbolically shown in FIG. 1, for cleaning in the direction of the arrow 5.
- a fan 4 which is only symbolically shown in FIG. 1, for cleaning in the direction of the arrow 5.
- the product to be treated is fed in at the top left via a product inlet 6 and a transition piece 8 directly onto the upper vibrating table 2, directly following the product inlet 6 and at a distance above the upper one Swing table 2 is arranged a guide cover plate 9 which forms a feed channel 10 together with the upper swing table 2, the cross section of which increases in the direction of the center of the upper swing table 2.
- the vibrating table 2 has, apart from a short area 11 at its lower end, which is provided for product dropping, a smooth, finely perforated flat plate 12, under which there is a grid 13 which is fastened to spacer surfaces 14. Between the plate 12 and the grid 13, bulkhead-like sections or fields 15 are formed which run transversely to the longitudinal direction of the upper vibrating table 2.
- Each field 15 is provided with a ball 16 for keeping the fine perforations in the plate 12 clean.
- the short area 11 for the diarrhea has a large number of through openings 17 evenly distributed over its entire surface.
- a layer separating knife 18 is arranged at the lower end of the upper vibrating table 2, which is at a distance of about a finger thickness from the vibrating table surface and clearly guides the two incoming layers (lower layer enriched with heavy goods, light goods fraction arranged above) supports.
- a slide 19 is arranged, which is opposite from the end of the upper vibrating table 2 and in one to the inclination of the vibrating tables 1 and 2 is directed towards a central region of the lower vibrating table 1 and the end of which is located approximately half the height of the distance between the two vibrating tables 1 and 2.
- the stone reading table 1 and the layer table 2 are arranged essentially parallel to one another and at an angle cC to the horizontal in a corresponding common inclined position.
- the slide 19, on the other hand, has an angle ⁇ to the horizontal which is chosen such that the slide 19 still has at least a slight inclination to the horizontal at all conceivable inclined positions of the two vibrating tables 1 and 2.
- the lower vibrating table 1 (stone reading table) can be divided into three fields A, B and C of approximately the same size. Since the product is always "in flow" on a continuously coated vortex table, as is shown by the lower vibrating table 1, it is of course difficult to assume local limits for certain functions unless these are brought about by solid walls or additional forces. Only in the sense of an attempt to explain it is assumed that in the field A on the lower vibrating table 1 there is mainly a stratified flow, in the middle field B ("middle area" of the lower vibrating table 1) there is a classic fluidized bed and in the field C a discharge flow.
- a partition 20 and an adjusting valve 21 are provided at the lower end of the upper vibrating table 2, so that a possibly occurring quantity of false air can be kept very small. So that no disturbing false air enters from outside, all outlets are provided with a lock-like closure.
- the lower vibrating table 1 (stone reading table) has an outlet 22 for the cleaned goods with a product lock 23 and with a stone end separation zone 24, a stone discharge channel 25 and a stone lock 26.
- Both the product lock 23 and the stone lock 26 are, as is known per se, formed from rubber-like material and open as soon as there is sufficient product in the outlets 22 and 25, respectively. By contrast, the locks 26 and 23 are closed without a product.
- the stone end separation zone 24 is formed on its top by a guide plate 24 and below by a closed bottom section 28 and a ventilated bottom section 29 which extend over the entire width of the table surface.
- the whole device is by means of a vibrating drive 30 correspondingly to the arrows 31 is vibrated, wherein the Schwing ⁇ direction substantially through the center of gravity S (see FIG. 1) and at an angle between 20 0 and 40 0 to the longitudinal extent of the two Vibration tables 1 and 2 are generally directed in the direction from the outlet 22 to the feed channel 10.
- the device is also resiliently supported by a height-adjustable joint support 32 and, in the area of the outlet 22, by a spring support 33. Due to the linear oscillating movement in the direction of arrows 31 and the corresponding support by means of articulated support 32 and spring support 33, the two oscillating tables 1, 2 are imprinted with a throwing oscillating movement with a conveyor component directed upwards.
- the device has a product control flap 40 at the product inlet 6, which regulates itself via a lever 41 and a spring 42 in such a way that when a certain amount of product is present the flow is open, but the passage is closed in the absence of sufficient product. This can prevent any undesired air entry at this point.
- the product inlet 6 is connected via a flexible bellows 43 to a product feed pipe 44 which is part of the fixed installation of the overall device.
- the bellows 43 enables the device to perform the relative movement required for a swinging movement.
- a large bellows 45 there separates the vibrating device from a stationary connection piece 46, which is firmly connected to an aspiration line 47.
- An air adjustment flap 48 is arranged in the connecting piece 46, with which the total amount of air can be regulated.
- the articulated support 32 is held both at the bottom and at the top by means of a bearing 49 or 50 which permits rotary movements.
- the length of the articulated support 32 can be adjusted by means of a threaded rod 51 and a rotary lever 52, so that the two oscillating tables 1 and 2 can hereby be brought into an optimally inclined position.
- a compression spring 53 can also be installed within the joint support 32, which allows the upper table ends to be deflected slightly.
- the vibrating drive 30 is not rigidly connected to a crossmember 54, but rather via a special joint 55 with it in such a way that only a linear force component in accordance with the direction of the arrow 31 is actually transmitted to the overall device and, due to the special mounting, the vibrating tables 1 and 2 throwing swing movement described is impressed.
- FIGS. 3 and 4 now show the special floor construction (sandwich construction), FIG. 3 showing both the position in FIG. 4 drawn cross-section HI-HI, as at the same time represents the longitudinal section HI-IH.
- the sandwich construction shown in FIG. 3 for the lower vibrating table 1 (stone reading table) has a perforated plate 60 at the bottom with very fine holes 61 and a rough mesh screen 62 at the top, which is separated from the perforated plate 60 by bulkhead walls 63 running transversely to the longitudinal direction of the floor.
- the partition walls 63 between the perforated plate 60 and the mesh 62 make a field division so that the air is prevented from executing transverse movements between the perforated plate 60 and the mesh 62.
- Hole plate 60, mesh grid 62 and bulkhead walls 63 together form the sandwich-like structure.
- the overall structure of the lower oscillating table 1 represents a resistance to the air flowing through which is virtually independent of the thickness of the material layer lying on the lower oscillating table 1 and essentially the same over the total area of the lower oscillating table 1.
- This can also be favored by the fact that the perforation in the finely perforated plate 12 of the upper vibrating table 2 is chosen favorably.
- an almost constant air resistance over the entire lower crop support can be achieved regardless of the local and current position Good layer thickness can be achieved on the lower vibrating table 1.
- the sum of the hole cross sections of the finely perforated plate 12 is preferably selected to be less than (or at most) equal to the tenth part of the total area, but at the same time more than twice as large as the total area of the passage cross sections of the good support formed as a mesh grid 62. It is also essential here that the holes in the plate 12 are evenly distributed over the surface of the fluidized bed table and that the distribution of the holes and their distance from the material support formed as a mesh screen 62 are selected such that the air flowing through the holes makes the material support 62 is subjected to a substantially uniform dynamic pressure. The best results could be determined if the sum of the hole cross sections in the plate 12 was about 3 to 8% of the total area of the crop would be 62.
- the main difference between the solutions according to FIGS. 2 and 5 is that in the device in FIG. 2 only the stones or the heaviest parts are read out of the entire product flow, but in the device in accordance with FIG. 5 also a separation into a heavy one Grain fraction 70 and in a fraction 71 of the lightest parts and in the stone fraction 72.
- the device according to FIG. 5 has a grain outlet 73, a light material outlet 74 and a stone outlet 75, with each outlet here also being provided with a corresponding product lock in order to prevent the entry of false air.
- the embodiment of a device according to the invention shown in FIG. 5 can be used in all cases in which the quality requirements for the division into the grain fraction and the light fraction are not too great.
- the ratio of the upper light material flow 76 to the lower grain flow 77 can be influenced within certain limits by changing the inclination of the vibrating tables 1 and 2 and the amount of air flowing through them.
- the device according to the invention is particularly suitable for stone selection in cereals, it is to be expected that the device according to the invention and the method according to the invention can also be used equally for other bulk goods with similar properties for similar purposes.
