Definitions
- the invention relates to a separation device.
- a material flow When processing a material mixture, a material flow must be separated into different fractions.
- sieving for example by rotary drum sieves, vibrating screens or the like, into fractions of different particle sizes.
- this sieve overflow parts are still contained, which must be further separated in a subsequent separation process.
- lightweight parts are present, such as films, which must be separated from the batch.
- the object of the present invention is therefore to provide a separating device with which a material flow from a sieve overflow into a plurality of fractions can divide in particular organik restrooms, inert material can be separated better from other material.
- the separating device according to the invention for separating different material fractions from an input material mixture in this case comprises a gradient having, in particular in its main longitudinal extension direction parallel to the direction of gravity flow channel.
- This flow channel has an inner space, a first end area and a second end area opposite the first end area.
- a material input region is arranged, which serves for feeding the input material mixture into the interior of the flow channel.
- an outlet is arranged in the first end region of the flow channel, through which a, in particular a light material-containing, air flow can escape from the flow channel.
- the separating device according to the invention further comprises at least one conveying means, which promotes air through the flow channel.
- the air from the output described above is conveyed by suction.
- the input material mixture should be fine grain / fine grain, ie parts with grain sizes of less than 5 mm should at least largely not be included.
- the separating device comprises at the second end region of the flow channel a cross-flow device connected in fluid communication with the flow channel.
- a cross-flow device connected in fluid communication with the flow channel.
- This in turn comprises a separation chamber and an air inlet leading into it, through which the cross-flow device introduces air into the separation chamber in an angular direction of flow to the main longitudinal extension direction of the flow channel.
- the separation chamber comprises at least a first separation region adjacent to the air inlet and at least one second separation region located farther away from the air inlet.
- a separation device in particular designed as a baffle element, is arranged between the first and the second separation region.
- the separation device combines a down drafting process with a cross-flow sifting.
- light parts such as foils in the flow channel are initially drawn off the discontinued material flow towards the exit.
- heavier materials falling downwards are decelerated differently in their fall depending on the density and mass, and reach the area of the separation chamber in which they are blown and further separated by means of a cross flow
- stones or the like land in the first separation area or are reflected there by the separation device, and on the other hand, the lighter fraction through the cross flow over the separation device are passed away into the at least one further separation region. Due to the different braking of falling down in the flow channel material parts in particular organikreiche lightweight parts such as wood parts in the separation chamber can be easily separated from the other parts of the material flow.
- the flow channel below the material input region has at least one, in particular adjustable, air inlet.
- air inlet allows the additional intake of air.
- a flow-guiding surface is arranged in the separation chamber. In this way it is achieved that the blown into the separation chamber cross flow can be deflected via the flow guide and introduced into the flow channel. In this way, so the blown into the separation chamber air at least partially also be used to decelerate falling material parts in the flow channel.
- the flow guide surface is arranged such that an air flow introduced into the separation chamber through the air inlet is conducted at least partially between the flow guide surface and the separation device and around the flow guide surface into the flow channel.
- a separation in the separation chamber is initially carried out by the transverse flow, and the transverse flow is then correspondingly diverted via the flow guide into the flow channel.
- An embodiment has proven to be particularly advantageous in which the flow-guiding surface is arranged above the first and the second separation region, above the separation device and at least partially above the air inlet.
- the flow guide surface is arranged at a distance from the inner wall of the separation chamber. In this way, the flow guide surface can be flowed around by the transverse flow in the separation chamber.
- the flow guide surface can form a channel with the inner wall of the separation chamber on its side facing away from the separation device or the first and the second separation region. Through this channel, the flow can then be directed into the flow channel below the separation chamber.
- the shape of the flow-guiding surface As far as the shape of the flow-guiding surface is concerned, it has turned out to be particularly advantageous if the flow-guiding surface has a cross section tapering in the direction of the air inlet.
- the separation device can be a rigid structure per se, but are different geometric Designs conceivable.
- the separation device is designed as a drum or belt. It is preferably provided that the separation device is designed to be adjustable. In this way, one can set the separation behavior of the separation device, ie which material parts are separated by this, individually depending on the nature of the material to be separated.
- the separation device is pivotable and / or displaceable and / or rotatable. If the separation device is rotatable, it can be provided, in particular, that it is a separation device with an adjustable rotational speed and / or an adjustable direction of rotation.
- the separating device can be set up to further separate the material parts separated in the separation region.
- the first separation region branches off at least in a first and a second separation subregion separated therefrom with respect to the direction of gravity at the lower end.
- a first material inflow means is arranged in the first separation region, which is designed to flow into the first separation region falling, separated material.
- the second separation region branches at least in relation to the direction of gravity lower end in a first and a second Separationsunter Anlagenwitz.
- a second material inflow is arranged in the second separation region and adapted to flow into the second separation area falling, separated material.
- the first and / or second separation region comprises at least one detection means which is set up to recognize a specific material from a substance mixture. The recognition then helps to identify certain material parts from a batch targeted, weed out and then flow selectively.
- a control is preferably provided which temporarily activates the first and / or second material inflow means in response to a material part recognized by the detection means in order to flow into the recognized material part.
- the detection device can be of any nature. For example, it may be an NIR sensor. Such a sensor can be adjusted very selectively to very specific material components of a material mixture.
- the detector detects, for example, a plastic part, then this is flown through by a material inflow means and selectively removed from the rest of the material flow.
- the corresponding detector is preferably arranged in the direction of fall above the Materialanströmstoffs so that the Materialanströmstoff can be activated with the appropriate time delay and immediately deactivated again on the control upon detection of a separate part, so not more parts be detected and separated from the Materialanströmstoff, which should not be discarded.
- Preferred medium in said process is air.
- the outlet of the flow channel is connected to a line in which in the flow direction in series a separator, which are connected at least one conveying means and a filter means.
- the air coming out of the outlet, which contains light material, is separated from the light material at the separator.
- recirculation mode or partial recirculation mode provision can be made, in particular, for a return line leading to the air inlet branching off from the line. This is then passed back to the separation chamber in the region of the cross-flow device, namely at its air inlet.
- the air inlet to the crossflow device does not require a separate fan;
- the fan installed at the outlet of the flow channel can also be used for recirculation mode or partial recirculation mode.
- the branch of the return line between the at least one conveying means and the filter means or downstream of the filter means lies in the flow direction.
- separating device 1 has a substantially vertical, at least with a vertical component or a gradient provided flow channel 3.
- an air flow 5 is generated in the vertical direction Z, which leads from the lower end of the flow channel 3 to the upper end 36 thereof.
- a material input region 34 is arranged, through which a material flow 2 can be introduced with therein, to be separated parts in the flow channel 3.
- the air flow 5 is preferably generated by the fact that behind the end 36 of the flow channel 3, a fan is connected. By the moving air in the flow channel 3, the material 2 is sucked in the material input area.
- an air inlet 31, 32, 33 can be provided at several points, via which additional air can be drawn in from the outside area.
- Such an air inlet may be provided with a controllable valve, so that the intake amount can be varied.
- a separation chamber connects, which is part of a cross-flow device 4 and a plurality of sections 44, 45, 49 includes.
- a channel 41 is charged with air, which injects air in the example shown transversely, in particular perpendicular, to the vertical direction Z or to the main longitudinal extension direction of the flow channel 3 into the separation chamber.
- the amount of air to be injected can be varied via a valve or frequency converter 43.
- another air inlet 33 may also be provided above the channel 41, which sucks air into the region 49 of the separation chamber immediately before the start of the flow channel 3.
- a first separation region 44 Adjacent to the channel 41, a first separation region 44 is present in the separation chamber. Separately separated by a separation device 46, there is a further separation region 45.
- the separation device 46 is designed as a partition which can be pivoted in the direction of the arrow P 2 and can be extended or shortened in the direction of the arrow P 1.
- the device 1 functions as follows: As already described, the air flow 5 is generated in the flow channel 3 by means of a fan, a material mixture 2 being supplied to the material inlet region 34 and being sucked into the interior 35 of the flow channel 3 as a result of the air flow. Lighter objects in the stream 2 of material are entrained in the upward flow and reach the exit 36, while heavier parts due to gravity, sink down towards the separation chamber. There they reach the area 49 of the separation chamber. Since a cross flow is blown into the separation chamber via the fan 42 and the channel 41 at this point, the parts of the material mixture present in the region 49 are seized as a result of the transverse flow and thrown in the direction of the separation device 46.
- the inflow direction of the crossflow can be varied in an advantageous embodiment, for example, by the fan can be pivoted with the channel 41.
- the separation device 46 is arranged in the example shown as a rotatable (arrow P2) and displaceable in two spatial directions P5, P6 drum between the two separation regions 44 and 45, on the other hand, a guide surface 47 is provided in the separation chamber, which ensures that the through the channel 41 incoming air not only causes parts of the falling material mixture in the separation areas 44 and 45 reach, but also generates an air flow in the drawing first below the guide surface 47 therethrough, then the channel 41 facing away from the Guide surface 47 around this and finally passes over a lying between the guide surface 47 and wall of the separation chamber flow path 48 again in the region 49 and from there into the flow channel 3. With this measure, therefore, an additional air flow is achieved, which further enhances the buoyancy in the flow channel 3.
- FIG. 2 is exemplary in FIG. 2 shown separating device 1 shown in the system diagram.
- the so-laden air enters a separator 9, on which light parts present in the air stream, such as films, paper or the like are deposited.
- the air flowing through the fan 10 then passes to a filter 12, on which particles still present in the air are filtered out and optionally collected in a collecting device 13, while the cleaned air 14 leaves the line 8 behind the filter 12.
- the system works with the intake of fresh air, and also the fan 42 blows fresh air into the system for the cross flow.
- FIG. 5 A variant of in FIG. 4 shown configuration is in FIG. 5 shown, the only difference is that here the return line 16 between the fan 10 and filter 12 is located.
- This configuration is particularly advantageous when the dimensioning of the filter 12 is important, since in this case the use of energy due to smaller volume flows through the filter 12 is minimized.
- a somewhat modified separating device 1 can be used for this configuration, as in FIG. 6 is shown.
- the two separation sections 44 and 45 are split once again into respective separation subsections 44a and 44b on the one side and 45a and 45b on the other side.
- materials that enter the separation regions 44 and 45, once again separated from each other and in corresponding outputs 6, 6 'and 7', 7 are collected.
- the material falling into regions 44 and 45 is detected by detectors 44d and 45d, respectively.
- the detectors 44d and 45d can preferably be designed such that they can detect certain materials (for example plastics, wood) from a flow of material.
- the detectors may be those based on NIR technology. Detected parts can then be targeted via a controller, not shown via Materialanströmstoff, which may be small air nozzles, blown across the direction of fall and then spent in the corresponding Separationsunterabête 44 a and 45 a.
- the separation device 1 according to the invention may comprise more than two separation sections in the region of the separation chamber.
- the separation device 1 comprises a total of three separation sections 44, 44 'and 45.
- the air blown into the separation chamber by the (P3) channel or air inlet 41 which is in particular pivotable together with the fan 42 is separated at a first separation device 46 as described above and parts are removed enter the air flow in the separation regions 44 and 44 '.
- a second separation device 46 ' is provided. If more than three separation zones are provided, the number of separation devices must also be increased accordingly.
- a further air inlet 41 'with a ventilating fan 42' which can also be designed to be pivotable (P3 ') around the inflow direction to change. It is possible for portions 44 'behind the first separation device 46 to fall down or be held back by the second separation device 46', which should not actually be collected at this point.
- Both the first and the second separation device 46, 46 'or possibly any further separation devices can again be rotatable (P2, P2') and / or displaceable or designed as simple partitions, as has already been described above.
- this embodiment of the separation device according to the invention is arbitrary with the other separation devices according to the Figures 1-6 can be combined.
- any number of separation regions can be provided, and it is also possible to provide any number of subseparation regions.
- material mixtures can be divided into different fractions, wherein the device according to the invention is particularly suitable for separating off organically containing inert fractions and light fractions from a material stream.
