Definitions

the present invention relates to a stone separator with air classifier for processing a material mixture and a method thereof.
Such devices are known from the prior art and are used for the preparation of material mixtures such as biomass, wherein contained in the biomass foreign bodies such. As stones, films or similar components are separated.
material mixtures such as biomass
As stones, films or similar components are separated.
the problem may be that z. B. stones on to be sucked by a suction device components such. As foils or other lightweight materials and therefore they can not be sucked off the suction or not good enough. Generally it can be problematic to stones, inert materials and / or heavy parts, which are as described on the light fabrics can be separated from the input fraction or from the material mixture introduced into the device.
the object of the present invention is therefore to provide an improved apparatus for processing a material mixture which overcomes the disadvantages mentioned.
a device for processing a material mixture with the features of claim 1.
the device is used in particular for separating stones, inert materials and / or heavy parts with a first conveyor belt, which is connected to a chamber, wherein in the interior of the chamber at least one pressure blower for generating a directed from below to the incident material in the chamber material mixture air flow is provided , wherein at least two collecting means offset along the chamber bottom with different distance to the chamber side entry point of the material mixture and separated by at least one movable on the bottom of the chamber separating vertex which extends from the chamber bottom in the direction of the chamber top, are separated from each other in terms of area, wherein in a first separation area a first Material group such as stones and / or inert materials and / or heavy parts with the least fluid resistance of all material groups of the material mixture of the material flow is at least partially separated, wherein the device of a Fluidstro m and a separable by means of the device material mixture of at least three different material groups as a material flow, and wherein
the suction of lighter material flow components that this together with the fluid flow in the calming zone of the second separation region downstream of a Fluidleitblechs or more Fluidleitbleche in their movement be slowed down and guided and are so easily separated by means of the first negative pressure range of the material flow.
no or less turbulence occurs in the area of the stones and / or inert materials, so that no lightweight materials can flow back into the fraction or material group of the stones / inert materials / heavy parts.
the suction in the region of the first negative pressure range for the targeted air flow in the interior of the device is authoritative.
the first negative pressure region or the exhaust fan which is assigned to the first negative pressure region, thus serves, on the one hand, the necessary air guidance and, on the other hand, the first separation of lightweight materials, films, etc.
fluid resistance refers to the tendency of the individual groups of materials to be entrained by a fluid stream. Above all, it is influenced by the coefficient of air resistance and the density of the material groups or their components.
At least one second conveyor belt, at least one fluid guide plate, a second vacuum region and a total of at least four separation regions are provided.
the total of at least four separation areas allow a better quality separation of the material mixture in the different material groups.
different separation methods are combined in such a way that the least possible effort is required to achieve the desired separation result.
Fluidleitblech refers to a portion of the device for targeted air guidance, which is designed to direct the flow of material and the fluid flow, both of which flow through the device, while minimizing turbulence or exclude and lightweight materials u. ⁇ . prevent it from flowing back into the fraction or material group of stones / inert materials / heavy parts.
the second and a third material group are at least partially separable from each other by means of Fluidleitblechs and at least partially separated from each other on the second conveyor belt.
the second material group is the material group with the greatest fluid resistance, which is thus most easily separable from the material flow by means of negative pressure regions.
the third group of materials which can be separated from the second material group, inter alia by means of the Fluidleitblechs can also consist of stones, inert materials or heavy parts, but the components of the third group of materials, in contrast to the components of the first group of materials may be on average smaller and / or one of the components of the first group of materials have different fluid dynamic behavior, so that they are separated by means of the air flow generated by the pressure fan from the constituents of the first group of materials and are further separated by the Fluidleitblechs of the components of the second group of materials.
the fluid guide plate directs the components of the second and third material groups in different ways onto the second conveyor belt provided below the fluid guide plate, thereby resulting in a third separation in a third separation region.
the conveyor belt can be designed as a discharge belt and second and third material group can be separated from each other and layered horizontally, but not removed from the flow of material, present on the second conveyor belt.
the second and third material groups are at least partially separated from one another.
the second material group is the material group with the greatest fluid resistance of all material groups of the material mixture and z.
films and / or film parts comprises, wherein the second group of materials rests largely on the third material group on the second conveyor belt downstream of the fluid guide plate.
a fourth separation region to comprise the second negative pressure region, wherein a part of the second material group still remaining in the material flow can be at least partially separated from a main direction of the material flow by means of the second negative pressure region in a vertical direction.
the pre-separation previously carried out by means of the fluid guide plate can thus advantageously be used to remove the now exposed components of the second material group, which have not been separated from the first negative pressure region, from the material flow by means of the second negative pressure region.
the two negative-pressure regions can be subjected to negative pressure by means of a common pressure source or by means of separate pressure sources.
a simple running, common pressure source such as a suction fan, this can have the advantage that the entire device is easier and thus cheaper to provide.
the operation by means of two separate pressure sources is advantageous because z. B. as a whole higher suction at the two negative pressure areas are achievable or it is possible to get along without cumbersome compressed air lines from a pressure source to the two vacuum areas.
FIG. 1 shows a schematic diagram of the device 1 according to the invention for the preparation of a material mixture.
the material mixture is first introduced via a receiving means 2 in the device 1 and passed from the receiving means 2 to a first conveyor belt 3.
the first conveyor belt 3 conveys the material mixture into a chamber 4, wherein the material mixture is transported by the first conveyor belt 3 in a direction vertically upward that the material mixture within the chamber 4 can fall in the direction of the chamber bottom 5.
the material mixture is detected by the air flow of a pressure blower 6, which is directed from below onto the material mixture entering the chamber 4.
a pressure blower 6 which is directed from below onto the material mixture entering the chamber 4.
components of the material mixture are detected more or less strongly by the air flow and offset according to their fluid resistance.
two collecting means are arranged offset along the chamber bottom 5 and separated from one another by a separating vertex 7 arranged on the chamber bottom 5.
the separating vertex 7 extends in this case from the chamber bottom 5 approximately in the direction of the chamber top 8.
the separating vertex 7 defines a first separation region 30 in which a first group of materials, which may consist of stones, inert materials and / or heavy parts, for example Collecting means is divided.
the separating vertex 7 is adjustable for this purpose, so that both its length and its angular position, as indicated by the arrows, can be adjusted depending on the properties of the material mixture.
a collecting container 9 is provided, which is located to the left of the separating vertex 7 and directly below the right end of the first conveyor belt 3.
a conveyor belt, a Quunterstrageband or other device is conceivable, which is suitable for collecting or separating material components.
a second conveyor belt 10 is provided to the right of the separating vertex 7 in the illustrated embodiment.
a fluid guide plate 11 is provided, on the rear side and thus in the slipstream a calming zone 12 is provided.
the fluid guide plate 11 prevents light substances from falling into the stone fraction or the collecting container 9.
a first, two-part negative pressure region 13 extends, by means of which a second material group can be separated at least partially in a direction horizontally laterally from the main direction of the material flow 100.
the components of the material stream 100 which can be detected by the second vacuum region 14 provided on the second conveyor belt 10 can be sucked off, without the suction being hindered by heavier stones or similar materials lying on lighter parts of the film.
the negative pressure regions 13, 14 are acted upon in the embodiment shown by separate pressure sources 15 with negative pressure.
pressure sources 15 for example, exhaust fans come into question.
a common pressure source 15 the two vacuum areas 13, 14 applied via corresponding pressure lines with negative pressure.
the components of the material stream 100 removed by means of the vacuum regions 13, 14 can be completely removed from the material stream 100 and transferred to another storage or landfill device. This is indicated by the arrow "P".
FIG. 2 a similar representation of the stone separator with air classifier FIG. 1
FIG. 2 only the four separation areas 30, 40, 50, 60 and a few other components are shown here.
the material flow 100 of its main direction from the first conveyor belt 3 to the second conveyor belt 10 is first detected by the pressure fan 6 as described above. Components of the material flow 100, which are less easily detected by the air flow of the pressure blower 6, are separated from the separating vertex 7 between sump 9 and second conveyor belt 10.
the third separation region 50 comprises the fluid guide plate 11, by means of which a separation of the second and third material group is feasible, so that they on the second conveyor belt 10 at least partially separated from each other and do not enter the area stones / inert materials / heavy parts by turbulence in the context of targeted air.
the fourth and last separation region 60 comprises the second negative pressure region 14 and removes in the region of the second conveyor belt 10 the remaining light components of the material stream 100 resting on the second conveyor belt 10 at the top.
