Abstract
Description
Technical Field
[0001] This utility model relates to a production line for processing polycrystalline silicon, specifically to a centralized material processing production line for polycrystalline silicon. Background Technology
[0002] Siemens process polysilicon, after reduction vapor deposition, forms U-shaped rod-like polysilicon. This polysilicon, due to its varying quality, is further divided into three types: carbon-head polysilicon, coral polysilicon, and dense polysilicon. These three types require different processing techniques, making it impossible to mix them in production.
[0003] The processing technology for U-shaped polycrystalline silicon rods is as follows:
[0004] The first step is to remove about 500mm of the bottom length of the U-shaped polycrystalline silicon rod and store it. This part is the carbon head material.
[0005] The second step involves removing the 500mm silicon rods and then dividing them into dense material and coral material. Both the coral material and the dense material are processed on an automated production line.
[0006] Due to the different qualities of dense silica and coral silica, they cannot be mixed and processed simultaneously. Therefore, when processing a batch of material in the reduction furnace (approximately 12 tons, stored in five carts), the dense silica must be processed first, the entire production line cleaned, and then the remaining coral silica processed. However, due to limited space, it is impossible to store too many silica rod carts; it is not possible to process the dense silica from the 12 tons of material before processing the remaining coral silica. Utility Model Content
[0007] To address the technical problem that existing technologies cannot process all dense materials before processing coral materials, this invention provides a centralized material processing line for polycrystalline silicon. By setting up a temporary storage area for coral materials, the coral materials can be processed after the initial processing.
[0008] The technical solution of this utility model is:
[0009] A centralized material processing line for polycrystalline silicon, comprising:
[0010] Carbon feedstock processing line;
[0011] The dense material processing line is sequentially set up with a water quenching zone, a pre-crushing zone, a primary selection zone, a secondary crushing zone, a sorting zone, and a packaging zone.
[0012] The coral material processing line includes a temporary storage area, and the unloading area of the temporary storage area is located on the secondary crushing area of the dense material processing line.
[0013] Optionally, the dense material processing line includes a long dense material processing system and a short dense material processing system:
[0014] The water quenching zone, pre-crushing zone, primary selection zone, secondary crushing zone, sorting zone, and packaging zone constitute the long and dense material processing system;
[0015] The short, dense material processing system has the same structure as the coral material processing line and is connected to the secondary crushing zone.
[0016] Optionally, the long dense material processing system, the short dense material processing system, and the coral material processing line share the secondary crushing zone, sorting zone, and packaging zone;
[0017] Furthermore, the secondary crushing zone, sorting zone, and packaging zone are only connected to the long dense material processing system, the short dense material processing system, or the coral material processing line at a time.
[0018] Optionally, both the short dense material processing system and the coral material processing line have a loading area and a unloading area in their temporary storage areas. The unloading area feeds the material into the secondary crushing area of the long dense material processing system.
[0019] Optionally, the loading area of the temporary storage area includes a material box, which is located on the operating system and the flipping system.
[0020] Optionally, the temporary storage areas of both the short dense material processing system and the coral material processing line are located above the long dense material processing system and are arranged along the layout direction of the long dense material processing system.
[0021] Optionally, the unloading area of the short dense material processing system's temporary storage area and the unloading area of the coral material processing line's temporary storage area share the same pipe structure, which contains a diversion component.
[0022] Optionally, the carbon feed processing line is sequentially configured with a crushing zone, a sorting zone, and a packaging zone.
[0023] Optionally, a pretreatment zone is also provided before the crushing zone of the carbon feed processing line.
[0024] Optionally, the carbon head material processing line and the dense material processing line share the same packaging area.
[0025] Compared with the prior art, the beneficial effects of this utility model are:
[0026] Coral material produced during the production process is stored in a temporary storage area connected to the secondary crushing zone of the dense material processing line. This solves the storage problem caused by the inability to mix materials during processing. In this technical solution, by setting up a temporary storage area, a batch of coral material can be stored temporarily without stopping the dense material processing line midway. After the dense material processing is completed, only the secondary crushing, sorting, and packaging areas need to be cleaned, reducing the time spent cleaning the dense material processing line and thus shortening the waiting time for the coral material, reducing storage pressure.

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0030] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0032] See Figure 1This embodiment discloses a centralized material processing line for polycrystalline silicon, including a carbon head material processing line 10, a dense material processing line, and a coral material processing line 30. The carbon head material processing line 10 is used to process carbon head material with a length of approximately 500mm from the bottom of a U-shaped polycrystalline silicon rod. The dense material processing line is used to process dense material, and the coral material processing line 30 is used to process coral material.
[0033] Specifically, the carbon material processing line 10 and the dense material processing line are arranged side by side. The dense material processing line includes a water quenching zone 211, a pre-crushing zone 212, a primary selection zone 213, a secondary crushing zone 214, a sorting zone 215, and a packaging zone 216 arranged sequentially. The coral material processing line 30 includes a temporary storage zone 31, which has a loading zone 311 and a unloading zone 312. The unloading zone 312 of the temporary storage zone 31 is connected to the secondary crushing zone 214 of the dense material processing line, thereby forming the coral material processing line 30 with the temporary storage zone 31, secondary crushing zone 214, sorting zone 215, and packaging zone 216 arranged sequentially.
[0034] In this embodiment, the coral material produced during the production process is stored in a temporary storage area 31, which is connected to the secondary crushing area 214 of the dense material processing line. This solves the storage problem caused by the inability to mix the materials. In this technical solution, by setting up the temporary storage area 31, a batch of coral material can be temporarily stored without stopping the dense material processing line midway. After the dense material processing is completed, the secondary crushing area 214, sorting area 215, and packaging area 216 can be cleaned, reducing the time spent cleaning the dense material processing line and thus shortening the waiting time for the coral material, reducing storage pressure.
[0035] Preferably, such as Figure 1 As shown, the aforementioned dense material processing line includes a long dense material processing system 21 and a short dense material processing system 22. The long dense material processing system 21 includes a water quenching zone 211, a pre-crushing zone 212, a primary selection zone 213, a secondary crushing zone 214, a sorting zone 215, and a packaging zone 216. The short dense material processing system 22 has the same structure as the coral material processing line 30, also having a temporary storage zone 221, which is also located on the secondary crushing zone 214.
[0036] As can be seen from the above, the long dense material processing system 21, the short dense material processing system 22, and the coral material processing line 30 share the secondary crushing zone 214, the sorting zone 215, and the packaging zone 216. However, the secondary crushing zone 214 is only connected to the long dense material processing system 21, the short dense material processing system 22, or the coral material processing line 30 at a time, so that only one of the three production lines can be working at a time.
[0037] In this embodiment, since short dense materials cannot meet the requirements of water quenching, the dense material processing line is divided into a long dense material processing system 21 and a short dense material processing system 22, thereby improving the processing efficiency of all dense materials.
[0038] In addition, the temporary storage area 221 of the short dense material processing system 22 also has a feeding area 222 and a discharging area 223. The feeding area 222 feeds materials into the temporary storage area 221 (short dense material is fed into the temporary storage area 221 of the short dense material processing system 22, and coral material is fed into the temporary storage area 31 of the coral material processing line 30), and the discharging area 223 feeds the materials into the secondary crushing area 214 of the long dense material processing system 21.
[0039] Generally, the structure of the temporary storage area 221 of the short dense material processing system 22 is the same as that of the temporary storage area 31 of the coral material processing line 30. Taking the structure of the temporary storage area 221 of the short dense material processing system 22 as an example, its feeding area 222 includes a material box. The material box is located on the operating system and the flipping system. The material is lifted or transferred by the transfer system to reach the storage location. Then, the material in the material box is sent to the storage location by the flipping system.
[0040] In one specific embodiment:
[0041] In order to make comprehensive and effective use of the space in the factory, the temporary storage area 221 of the short dense material processing system 22 and the temporary storage area 31 of the coral material processing line 30 are both set above the long dense material processing system 21 and are arranged along the layout direction of the long dense material processing system 21, so that the temporary storage area 31 occupies the vertical space and reduces the amount of horizontal space occupied.
[0042] Preferably, the feeding area 312 of the temporary storage area 31 of the short dense material processing system 22 and the feeding area 312 of the temporary storage area 31 of the coral material processing line 30 are of the same pipe structure. This pipe is vertically arranged, and its bottom is connected to the secondary crushing zone 214. The pipe structure is equipped with a diversion component, so that the secondary crushing zone 214 receives only long dense material, segmented dense material, or coral material at a time.
[0043] In another specific embodiment:
[0044] The carbon material processing line 10 is provided with a crushing zone 11, a sorting zone 12 and a packaging zone 13 in sequence. A pretreatment zone 14 is also provided in front of the crushing zone 11 of the carbon material processing line 10. The carbon material processing line 10 and the dense material processing line can share the same packaging zone 216.
[0045] The carbon head material processing line 10 allows for separate processing of carbon head material and can operate in parallel with the dense material processing line.
[0046] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
