Definitions
- the invention relates to a transport container containing at least three foil bags or at least three double foil bags, each of which is filled with silicon fragments.
- Polycrystalline silicon (polysilicon) is usually produced using the Siemens process (more like gas phase deposition process). Polysilicon is the starting material in the production of single-crystal silicon, which is produced, for example, using the Czochralski process. Furthermore, polysilicon is required for the production of multicrystalline silicon, for example by means of ingot casting processes. For both processes, the polysilicon obtained in the form of a rod by the Siemens process must generally be comminuted into fragments.
- the silicon fragments should be packaged with little contamination for transport.
- the packaging is usually in sealed foil bags or double foil bags made of plastic. Double-foil bags can reduce the risk of punctures from the mostly sharp-edged fragments.
- the bags are arranged in various quantities in outer packaging, mostly cardboard. The outer packaging can then be stacked on standard pallets and, if necessary, placed in containers.
- the bags can be punctured not only during filling, but also during transport, in particular due to vibrations, shock and displacement of the bags appear. As a rule, these events also lead to undesired post-crushing. In principle, the resulting fines must be separated in an additional work step before further use, as they have a negative effect on the further processing.
- the main cause of punctures and secondary shredding is the excessive freedom of movement of the bag in the outer packaging and the fragments in the bag itself.
- excessive packing density in the bag and/or the outer packaging promotes punctures and the associated contamination.
- a transport container is known from WO 2015/007490 A1, which contains at least two plastic bags with polysilicon fragments and has a packing density of 650 kg/m 3 to at most 950 kg/m 3 .
- the plastic bags are arranged partially overlapping and the total volume of each bag is 2.4 to 3.0 in relation to the volume of the fragments therein.
- the disadvantage is that the arrangement of the bags creates empty spaces and optimal use of space when loading freight containers is not guaranteed.
- a high packing density would be advantageous in order to be able to achieve maximum utilization of the payload of, for example, ISO containers (freight containers; cf. ISO standard 668).
- ISO containers light containers; cf. ISO standard 668.
- a middle way must be found that minimizes both the risk of contamination and the risk of secondary shredding.
- the object of the present invention arose from this problem.
- This object is achieved by a transport container containing at least three foil bags or at least three double foil bags, each filled with silicon fragments.
- the foil bags each have a packing density of 0.88 to 1.62 kg/dm 3 , preferably 0.99 to 1.49 kg/dm 3 .
- the double film bags each have a packing density of 0.68 to 1.15 kg/dm 3 , preferably 0.77 to 1.05 kg/dm 3 .
- the transport container containing the film bag has a packing density of 0.81 to 1.23 kg/dm 3 , preferably 0.89 to 1.14 kg/dm 3 .
- the transport container containing the double film bag has a packing density of 0.65 to 1.06 kg/dm 3 , preferably 0.73 to 0.97 kg/dm 3 .
- the packing density of the film bag or the double film bag is greater than or equal to the packing density of the transport container. Furthermore, the silicon fragments belong to at least one of the fragment size classes 0, 1, 2, 3 or 4.
- the packing density of the film bag is defined as the ratio of the weight of the silicon fragments contained (weight) and the bag volume.
- the silicon fragments are in the first foil bag, which is enclosed by the second foil bag.
- the packing density of the double film bag is defined as the ratio of the weight of the sample and the volume of the second film bag.
- the weight of all packaging materials can be disregarded when calculating packing density.
- the first and the second foil bag can have the same dimensions in the unfilled state. Furthermore, the first and the second foil bag can be made of the same material. However, the thickness of the foil can differ. If necessary, it can be preferred that the second film bag is made of a more durable material than the first film bag.
- the foil bags are preferably made of a plastic. This is preferably polyethylene (PE), polyethylene terephthalate (PET) or polypropylene (PP). Furthermore, the foil bag can consist of a two-layer or multi-layer composite foil. The thickness of the film or composite film is usually in a range from 10 to 1000 gm, preferably from 50 to 500 gm, particularly preferably from 100 to 300 gm.
- the film bags are generally hermetically sealed, with the sealing being by welding, gluing, sewing or positive locking can be done. If necessary, the foil bags are at least partially evacuated during filling. With regard to the design of the foil bags, their filling and sealing, reference can be made to EP 2 743 190 A1 and EP 2730 510 A1.
- the volume of the sealed foil bag can be determined by displacement in a water bath, with the displaced water corresponding to the bag volume.
- the packing density of the transport container is defined as the ratio of the weight of the sample and the internal volume of the transport container.
- the transport container is preferably made of cardboard and is in particular cuboid in shape (eg folding box, in which case the top and bottom can each be formed from four closing flaps).
- the film bag and the double film bag contain, in particular, silicon fragments of a fractional size class. They are preferably polysilicon fragments.
- a transport container usually contains silicon fragments of the same fragment size class. It may be preferable to combine foil bags or double foil bags filled with silicon fragments of different fracture size classes in one transport container. Furthermore, it may be preferred to mix silicon fragments from more than one of the fragment size classes 0 to 4 in a film bag or double film bag.
- the fragment size classes 0 to 4 (BGO to BG4) are defined based on the grain size of the fragments, the grain size being defined as the longest distance between two points on the surface of a silicon fragment.
- the fraction size classes summarize fractions with grain size ranges as follows.
- the silicon fragments can be classified using mesh screens, the edge length of the square meshes corresponding to the upper limit of a BG.
- DE 102013 218 003 describes A1 Classification method using vibrating screens and an opto-pneumatic classification method is known from DE 102006 016 324 A1.
- a BG preferably comprises at least 90% by weight of silicon fragments within the respective size range.
- the transport container allows a significantly larger amount of silicon to be transported per available volume than previous packaging for silicon, without promoting the formation of fines and punctures.
- the utilization of the permissible payload of ISO containers could be increased, resulting in significant savings in transport costs.
- the payload increases by up to 25%.

- the film bags each have a packing density of 1.07 to 1.61 kg/dm 3 , preferably 1.20 to 1.47 kg/dm 3
- the double film bags each have a packing density of 0.76 to 1.15 kg /dm 3 , preferably from 0.86 to 1.05 kg/dm 3 .

- the side length 1 and b of the stand-up pouch is 18.7 cm, the height h is 22.3 cm.
- the bags are arranged in one tier.
- the packing density of the transport containers is 0.64 kg/dm 3 .
- the CP3 is loaded with 16 transport containers. In this way, 20 pallets fit into a 20-foot ISO container, which corresponds to a net load of 14.4 t.
- a transport container contains 12 stand-up foil bags, each of which is filled with 5 kg of BG2 scrap polysilicon and has a packing density of 0.96 kg/dm 3 .
- the bags are arranged in 2 layers of 6 bags each.
- the packing density of the transport containers is 0.95 kg/dm 3 .
- the CP3 is loaded with 18 transport containers as shown in FIG. 20 pallets fit into a 20-foot ISO container, which corresponds to a net load of 21.6 t. With a 20-foot standard ISO container with a maximum payload of 21.67 t, 18 pallets are sufficient to use them including the packaging. This corresponds to a net payload of 19.44 t. When using HT containers, this can be loaded with 20 pallets (net load: 21.6 t).
- a transport container contains 18 stand-up foil bags, each of which is filled with 5 kg of BG3 scrap polysilicon and has a packing density of 0.95 kg/dm 3 .
- the bags are arranged in 2 tiers of 9 bags each (see Figure 8). With regard to the dimensions, reference can be made to FIG.
- the packing density of the transport containers is 0.94 kg/dm 3 .
- the CP3 is loaded with 12 transport containers as shown in FIG. 20 pallets fit into a 20-foot ISO container, which corresponds to a net load of 21.6 t. With a 20-foot standard ISO container with a maximum payload of 21.67 t, 18 pallets are sufficient to use them including the packaging. This corresponds to a net payload of 19.44 t. When using HT containers, they can be loaded with 20 pallets (net load:
- a transport container contains 9 stand-up foil bags, each containing 5 kg of BG2 scrap polysilicon and each having a packing density of 0.90 kg/dm 3 .
- the bags are arranged in one tier.
- the side length 1 and b of the stand-up pouch is 18.7 cm, the height h is 17.4 cm.
- the packing density of each transport container is 0.82 kg/dm 3 .
- the CP3 is loaded with 20 transport containers. In this way, 20 pallets fit into a 20-foot ISO container, which corresponds to a net load of 18.0 t.
- Determination of fines The determination was made via a transport simulation of typical loads caused by transport vibrations on a truck loading platform over a distance of 800 km.
- Transport-related impacts especially horizontal impacts when handling the pallets or transport containers, can correspond to two to three times the acceleration due to gravity (g).
- a vibrating plate was used for the simulation.
- BG2 polysilicon was transported in 10 kg double film flat bags in the following transport containers. The fines content was then determined by screening with a 2.0 mm mesh screen.
- Comparative transport container 1 (compare Tbl):
- Transport container 2 (TB2) on pallet (CP5, 540 kg) according to example 1 and Fig. 9).
- Transport container 3 (TB3) on pallet (CP5, 540 kg) according to example 4).
- Table 1 shows the packing density of the double film flat bag, the proportion of fines and the puncture for 5 (test 1 to 5) tested transport containers. Per test, 960 kg for Comparative TB1 and 1080 kg for TB2 and TB3 polysilicon (BG2) were evaluated. Puncture (Puncture Rate) refers to punctures of the outer bag. The fine content of TB2 and TB3 is significantly lower than that of See Tbl. The punctures are at a very low level and are not significantly different.
