Description

Technical Field

[0001] This utility model relates to the field of polycrystalline silicon crushing technology, and in particular to a silicon material support and a polycrystalline silicon crushing system. Background Technology

[0002] Polysilicon's initial product is silicon rods, which are then crushed and processed into finished products of different specifications for packaging. The crushing process begins with water quenching; the principle of a water quenching line is to heat the silicon before cooling it with water before crushing. Currently, to improve production efficiency, the support frame for the feeding operation on polysilicon crushing systems' water quenching lines is usually mechanically operated. During the feeding process, the support structure can affect the process, such as… Figure 1 As shown, silicon material can usually only be crushed into silicon rods with a length of 350-400mm. Therefore, silicon material that does not meet the size requirements cannot enter the crushing and quenching line for crushing, and the feeding is limited. For example, silicon material with microcracks cannot be crushed in the water quenching line, and the resulting small pieces are easy to fall into the heating furnace and get stuck. This results in the silicon rods that can pass through the water quenching line being limited in size, causing the problem of low water quenching capacity and waste of resources (many high-quality silicon materials that do not meet the requirements cannot be crushed in the water quenching line). Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a silicon material support and polycrystalline silicon crushing system, which solves the technical problem that existing silicon materials with microcracks or small sizes cannot be crushed on the water quenching line, resulting in low water quenching capacity and waste of resources.

[0039] Example 1

[0040] like Figure 2 As shown in the figure, this utility model application provides a silicon material support, including: a lifting structure 1 and a material frame 2 disposed on the lifting structure 1. The lifting structure 1 includes at least a set of support groups 11, and the material frame 2 is disposed on the support groups 11.

[0041] Furthermore, the support assembly 11 consists of at least two spaced-apart supports 111. The material frame 2 is made of a high-temperature resistant material, has a U-shaped bottom, and is provided with multiple drainage outlets 21 at its bottom. The number of supports 111 can be flexibly configured as needed; that is, a support assembly 11 can consist of multiple spaced-apart supports 111. For example, such as... Figure 2 As shown, the support group 11 consists of two supports 111.

[0042] Optionally, the upper surface of the bracket 111 is provided with a groove, which has a U-shaped structure. The bottom of the material frame 2 is adapted to the structure of the groove, and the bottom of the material frame 2 is set in the groove of the bracket 111.

[0043] Optionally, the support assembly 11 and the material frame 2 can withstand a high temperature of 800°C while the material is instantly cooled in water.

[0044] Optionally, the support assembly 11 and / or the frame 2 are made of silicon nitride (ceramic) or silicon carbide. They will not crack even after being heated to over 1000°C in air, followed by rapid cooling and then rapid heating.

[0045] Optionally, the bracket 111 has a recessed hole, and the bottom of the material frame 2 is provided with a corresponding insertion post, which is inserted into the recessed hole. In use, the material frame 2 can be easily removed, so that the bracket assembly 11 can be used to feed large-size silicon rods, making the silicon material support a dual-purpose device that can be set and changed as needed.

[0046] Optionally, a partition layer can also be provided on the inner walls of both sides of the groove of the bracket 111, and the insertion hole can be opened on the partition layer.

[0047] As an implementation scenario, in this scenario, the drain outlet 21 of the material frame 2 is a strip-shaped hole, which extends along the length direction of the material frame 2, and multiple strip-shaped holes are arranged along the width direction of the material frame 2.

[0048] As one implementation method, when in use, silicon material smaller than 350mm or high-quality silicon material with microcracks but not affecting quality can be placed in the material frame 2, and then moved to the designated position by the lifting structure 1.

[0049] Example 2

[0050] like Figure 3 As shown, this utility model application provides a material frame. Unlike embodiment 1, in this embodiment, the drain outlet 21 of the material frame 2 is a circular hole, and several circular holes are evenly arranged at the bottom of the material frame 2.

[0051] Example 3

[0052] This utility model application provides a lifting structure, which is based on embodiment 1, such as... Figure 2 As shown, in this embodiment, the lifting structure 1 also includes a movable plate 12. The bottom of the support group 11 is connected to the upper surface of the movable plate 12. The support group 11 and the material frame 2 disposed on the support group 11 can move along a preset path under the drive of the movable plate 12.

[0053] Optionally, both ends of the material frame 2 extend outwards from the moving plate 12, thereby forming extensions 22 on both sides above the moving plate 12. The extensions 22 facilitate cooperation with the lifting assembly.

[0054] Optionally, the movable plate 12 has at least two material picking slots located between the two supports 111. The material picking slots are not shown in the figure. The material picking slots are mainly for use with the lifting assembly, and the bracket of the lifting assembly can pass through the material picking slots to lift the material frame.

[0055] As an implementation scenario, in this scenario, multiple sets of support groups 11 can be spaced out on the movable plate 12, and the number of support groups 11 can be flexibly configured as needed. For example, such as Figure 2 As shown, two sets of support groups 11 are spaced apart on the movable plate 12. Each set of support groups 11 includes two spaced-apart supports 111. Each support 111 has a groove, and a material frame 2 is provided on the corresponding two grooves.

[0056] Example 4

[0057] This utility model application provides a lifting structure. Based on embodiment 1, the lifting structure 1 further includes a movable plate 12. The bottom of the support group 11 is connected to the upper surface of the movable plate 12. The support group 11 and the material frame 2 disposed on the support group 11 can move along a preset path under the drive of the movable plate 12.

[0058] In this embodiment, as Figure 4 As shown, a set of support groups 11 is provided on the movable plate 12. The support group 11 includes two spaced supports 111. Two grooves are opened on the supports 111 respectively. The grooves on both sides are arranged in pairs symmetrically. A material frame 2 is provided in each set of grooves.

[0059] Optionally, the movable plate 12 has at least two material picking slots located between two supports 111.

[0060] Example 5

[0061] This utility model application provides a lifting structure based on embodiment 3 or embodiment 4, such as... Figure 5 As shown, in this embodiment, the lifting structure 1 also includes a transverse movement mechanism 13 and a longitudinal movement mechanism 14.

[0062] The horizontal movement mechanism 13 is set on the ground, and the vertical movement mechanism 14 is installed on the horizontal movement mechanism 13. The horizontal movement mechanism 13 and the vertical movement mechanism 14 are driven to be connected. The vertical movement mechanism 14 is driven to be connected to the moving plate 12. The vertical movement mechanism 14 can move horizontally back and forth under the drive of the horizontal movement mechanism 13, and the moving plate 12 can move vertically up and down under the drive of the vertical movement mechanism 14.

[0063] In other embodiments, the movable board 12 can also be moved via a transmission line.

[0064] A method of using a silicon material tray: First, place silicon material smaller than 350mm or high-quality silicon material with microcracks but not affecting quality into the material frame 2. Then, move the material frame 2 to the designated location through the transverse moving mechanism 13. Then, cooperate with the longitudinal moving mechanism 14 to make the silicon material complete the heating or cooling process, such as entering a high-temperature heating box for heating, entering a water tank for cooling, or entering a drying section for drying.

[0065] Example 6

[0066] like Figure 6 As shown in the figure, this utility model application provides a polycrystalline silicon crushing system, including a high-temperature heating chamber 3, a water tank 4, a drying device 5, and a crushing device 6. A silicon material support is provided at the feed end of the high-temperature heating chamber 3, which is the silicon material support described in any of embodiments 1-5. The high-temperature heating chamber 3, the water tank 4, and the drying device 5 are each equipped with a lifting structure, which is basically the same as the lifting structure described in embodiment 5.

[0067] Example 7

[0068] This utility model application provides a polycrystalline silicon crushing system, see reference. Figures 5-7 As shown, the polycrystalline silicon crushing system also includes a lifting assembly 7, which is installed inside the high-temperature heating box 3, water tank 4, and drying device 5, and is used in conjunction with the corresponding lifting structure. The lifting assembly 7 includes a bracket 71 and a lifting cylinder 72. The upper surface of the bracket 71 has a groove that matches the bottom of the material frame 2; the movable end of the lifting cylinder 72 is connected to the bottom of the bracket 71, and the bracket 71 is used to drive the bracket 71 to move up and down, that is, the bracket 71 can move up and down under the drive of the lifting cylinder 72. The structure of the bracket 71 is basically the same as the structure of the support 111. When the moving plate 12 moves between the two brackets 71 or the material picking slot on the moving plate 12 corresponds to the two brackets 71, the lifting cylinder 72 is activated.

[0069] As an implementation scenario, in this scenario, when the moving plate 12 moves to the inside of the two brackets 71, the lifting cylinder 72 drives the brackets 71 to move upward, thereby lifting the material frame 2 upward. For example, after the lifting structure at the feeding end of the high-temperature heating box 3 transports the material frame 2 into the high-temperature heating box 3, the lifting component 7 lifts the material frame 2, and then the lifting structure inside the high-temperature heating box 3 supports the material frame 2. That is, the moving plate inside the high-temperature heating box 3 moves between the two brackets under the drive of the transverse mechanism, the lifting component 7 resets, and the support group inside the high-temperature heating box 3 supports the material frame 2 and heats the silicon material at high temperature. After the heating is completed, it is transferred to the water tank 4.

[0070] In another implementation scenario, when the moving plate 12 moves above the lifting assembly 7 and the material chute corresponds to the bracket 71, the lifting cylinder 72 drives the bracket 71 to move upward, thereby lifting the material frame 2 upward.

[0071] Example 8

[0072] This utility model application provides a polycrystalline silicon crushing system. Based on embodiment 6 or embodiment 7, the polycrystalline silicon crushing system further includes a flip-up lifting structure. The flip-up lifting structure is disposed between the drying device 5 and the crushing device 6, and is used to receive the silicon material dried from the drying device 5, and then pour the silicon material into the crushing device 6 for crushing.

[0073] Optionally, the flip-up lifting structure, based on embodiment 5, further includes a flipping mechanism 15. (See reference...) Figure 8 As shown, the flip-up lifting structure includes a support assembly 11, a movable plate 12, a transverse movement mechanism 13, a longitudinal movement mechanism 14, and a flipping mechanism 15. That is, the flip-up lifting structure adds a flipping mechanism 15 to the lifting structure, and the flipping mechanism 15 is located between the movable plate 12 and the longitudinal movement mechanism 14.

[0074] Specifically,

[0075] The longitudinal movement mechanism 14 is mounted on the transverse movement mechanism 13, and the flipping mechanism 15 is mounted on the longitudinal movement mechanism 14. Its output end is driven and connected to the moving plate 12. The flipping mechanism 15 can move vertically up and down under the drive of the longitudinal movement mechanism 14, and the moving plate 12 can rotate at a preset angle under the drive of the flipping mechanism 15 to pour out the silicon material in the material frame 2. For example, after the silicon material is dried in the drying device 5, the internal lifting structure transports the material frame 2 to the outlet of the drying device 5, and then the lifting assembly 7 lifts the material frame 2 from the lifting structure. Then the flip-up lifting structure operates, that is: the moving plate of the flip-up lifting structure moves to the space between the two brackets under the drive of the transverse mechanism, the lifting assembly 7 resets, the bracket group of the flip-up lifting structure supports the material frame 2, and then the transverse mechanism transports it to the crushing device 6. The longitudinal mechanism 14 lifts the material frame 2 upward to the inlet of the crushing device 6. Finally, the flipping mechanism 15 is activated, and the moving plate 12 rotates under the drive of the flipping mechanism 15 to pour the silicon material in the material frame 2 into the crushing device 6.

[0076] Example 9

[0077] A method for crushing polycrystalline silicon, implemented using a polycrystalline silicon crushing system, specifically includes the following steps:

[0078] Step S1: Place the 50 mm-350 mm sized blocks of high-quality silicon material with microcracks but which does not affect the quality into the material frame 2 of the silicon material holder.

[0079] In step S2, the material frame 2 is transported to the high-temperature heating box 3 by the lifting structure and heated to a temperature of 700-800℃.

[0080] In one embodiment, after the silicon material is transported into the high-temperature heating chamber 3, the material frame 2 can be lifted from the support structure by the lifting component 7, and then the support structure in the high-temperature heating chamber 3 can be used to support the material frame 2.

[0081] Step S3: After heating is completed, the material frame 2 is moved from the high-temperature heating box 3 to the water tank 4 by the lifting structure, so that the material frame 2 and silicon material enter the water for cooling, and the temperature drops to about 120°C instantly.

[0082] In one embodiment, after the silicon material is transported into the water tank 4, the material frame 2 can be lifted from the support structure by the lifting assembly 7, and then the support structure in the water tank 4 can be used to support the material frame 2 for cooling.

[0083] Step S4: After cooling is completed, the material frame 2 is moved from the water tank 4 to the drying device 5 by the lifting structure, so that the material frame 2 and the silicon material enter the drying device 5 for drying.

[0084] In one embodiment, after the silicon material is transported into the drying device 5, the material frame 2 can be lifted from the support structure by the lifting component 7, and then the support structure in the drying device 5 can be used to support the material frame 2.

[0085] In step S5, after drying, the material frame 2 is transported to the outlet of the drying device 5 via the lifting structure. Then, the lifting assembly 7 lifts the material frame 2 from the lifting structure, and then the tilting lifting structure transports it and pours it into the crushing device 6. Specifically, after the lifting assembly 7 lifts the material frame 2, the moving plate of the tilting lifting structure moves between the two brackets under the drive of the lateral movement mechanism. The lifting assembly 7 resets, and the support group supports the material frame 2 and transports it to the inlet of the crushing device 6. At this time, the tilting mechanism 15 is activated, and the moving plate 12 rotates under the drive of the tilting mechanism 15, thereby pouring the silicon material in the material frame 2 into the crushing device 6. The tilting angle is set so that the silicon material in the material frame can be poured out, such as 90 degrees.

[0086] It should be noted that in this embodiment, the transverse movement mechanism, longitudinal movement mechanism, and tilting mechanism are all mature existing technologies, and will not be described in detail here. Furthermore, the positions and sizes shown in the accompanying drawings are illustrative and are only used to express the concept of this technical solution, and do not involve limitations on the specific positions and sizes in actual embodiments. The high-temperature heating chamber, water tank, drying device, and crushing device are also shown illustratively and are all existing technologies.

[0087] Any aspects not described in detail in this embodiment are techniques known in the art.

[0088] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model.
