At the same time, this pipeline is located at the top of the silo, and scaffolds need to be erected for repair, which not only has great construction difficulty but also has a very high risk of danger.

[0003] In the current market technology, the wear-resistant materials used for pipelines conveying very hard granular materials are mainly ceramics, and there are mainly two forms: inner-lined ceramic pipes and ceramic tiles pasted. This pipeline is a non-standard design and needs to be customized, with a long processing time and high cost. Summary of the Utility Model

[0037] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0038] As Figure 1 、 Figure 2 and Figure 3 shown, the embodiment of the present utility model provides a blanking assembly for a powder grinding elevator, including: a blanking pipe 1, a baffle 2, and side baffle plates 3. The baffle 2 is installed on one side wall of the blanking pipe 1 and a plurality of them are arranged in sequence along the blanking direction of the blanking pipe 1. The side baffle plates 3 are installed inside the blanking pipe 1 and are located at both ends of the baffle 2. When the blanking pipe 1 is installed, it is inclined, and the baffle 2 is installed on the side of the blanking pipe 1 facing the ground. After the material enters the blanking pipe 1, it first accumulates in front of the baffle 2 and the side baffle plates 3 at the end of the blanking pipe 1 close to the discharge port of the elevator. When the material in front of the first baffle 2 and the first side baffle plate 3 accumulates to a certain height, the material will enter in front of the second baffle 2 and the second side baffle plate 3 for accumulation until the material in front of the last baffle 2 and the side baffle plates 3 accumulates, and the accumulated material forms a material stack layer 4. When blanking, the newly entered material in the blanking pipe 1 rubs against the material forming the material stack layer 4, reducing the friction of the material directly on the blanking pipe 1.

[0039] More specifically, when the blanking material is waste silicon particles, when the waste silicon particles flow through the blanking pipe 1, a material stack layer 4 is first formed from top to bottom on the bottom surface, gradually covering the side of the lower pipe facing the inside. After being covered, the waste silicon particles rub against each other, greatly reducing the friction of the waste silicon particles on the blanking pipe 1. Thus, the problem of production suspension and maintenance caused by wear and leakage of the blanking pipe 1 is reduced, and the long-term operation of the equipment process is realized.

[0040] In one of the embodiments, as Figure 1 、 Figure 2 and Figure 3 shown, the blanking pipe 1 includes: a bottom plate 11, side plates 12, and a top plate 13. The baffles 2 are arranged in sequence along the length direction of the bottom plate 11. Side plates 12 are arranged on both sides of the bottom plate 11 along its length direction, and the side baffle plates 3 are installed on the side plates 12. The top plate 13 is installed on the top of the side plates 12, and after installation, a rectangular blanking through groove is formed between the bottom plate 11, the side plates 12, and the top plate 13.

[0041] First, weld the stop bar 2 onto the bottom plate 11 and the side stop pieces 3 onto the side plates 12. Then, weld the side plates 12 onto the bottom plate 11. After welding, the side stop pieces 3 are located on both sides of the stop bar 2. Finally, weld the top plate 13 onto the other ends of the two side plates 12, so as to form a rectangular blanking through-channel among the bottom plate 11, the side plates 12, and the top plate 13.

[0042] In one embodiment, as Figure 3 shown, in order to make the materials in the blanking pipe 1 more evenly piled up, the stop bar 2 and the side stop pieces 3 are equidistantly arranged in the blanking pipe 1.

[0043] More specifically, the distance between two adjacent stop bars 2 is 10 mm - 30 mm. Preferably, it is 10 mm, 20 mm, or 30 mm, and the optimal one is 20 mm. The distance between two adjacent side stop pieces 3 is 30 mm - 50 mm. Preferably, it is 30 mm, 40 mm, or 50 mm, and the optimal one is 40 mm.

[0044] In one embodiment, in order to reduce the friction of the materials against the side stop pieces 3, the side stop pieces 3 are inclinedly installed, and after installation, a materials piling area is formed at one end of the side stop pieces 3 facing the materials inlet.

[0045] In one embodiment, in order to reduce the manufacturing cost of this blanking assembly, the blanking pipe 1 is made of Q235 steel plate; the stop bar 2 is made of square steel; the side stop pieces 3 are all made of steel blocks.

[0046] The blanking pipe 1 is made of Q235 steel plate with a thickness of 8 mm. Weld a 20-mm stop bar 2 onto the bottom plate 11 of the blanking pipe 1. This stop bar 2 is square steel (square steel is a profile, which can be cut according to requirements and then welded onto the bottom plate 11), and the arrangement spacing of the square steel is 20 mm; weld side stop pieces 3 with a size of 40×30×5 mm onto the connection between the bottom plate 11 and the side plates 12. The side stop pieces 3 are steel blocks, and their welding spacing is 40 mm. When the waste silicon particles flow through the blanking pipe 1, a materials pile layer 4 is formed from top to bottom on the bottom plate 11 of the blanking pipe 1, gradually covering the bottom plate 11 completely. Then, the silicon particles rub against each other, greatly reducing the friction of the silicon particles against the blanking pipe 1. Thus, it is possible to reduce the production suspension for maintenance due to the wear-through of the blanking pipe 1 caused by friction, and achieve the long-term operation of the equipment.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent substitution on some of the technical features. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
