Description

Technical Field

[0001] The utility model belongs to the technical field of polysilicon production, in particular to a silicon block sorting table. Background Art

[0002] The finished polysilicon product is a cylindrical product. According to customer needs, it is broken into rods and blocks of different specifications and sizes and then packaged into bags. At present, the crushing process is carried out by impact between silicon rods and manual knocking with tungsten-cobalt hammers. After crushing, the silicon blocks need to be sorted. Since the crushing is carried out in the form of knocking and impact, the crushed silicon blocks will have irregular shapes and different sizes, and will have sharp corners. Sharp corners can easily enter the sieve holes smaller than the silicon blocks, resulting in the silicon blocks with sharp corners easily clogging the sieve holes with smaller apertures. At this time, the sieve plate needs to be disassembled or the device shell needs to be disassembled to clean the blocked silicon blocks. This operation not only increases the workload of the staff, but also reduces the efficiency of silicon block sorting.

[0003] For example, the existing Chinese publication number is: CN205833641U, which is a polysilicon block sorting device, which: "comprising a power supply system and a large-size block sieve plate, a medium-size block sieve plate and a small-size block sieve plate with sieve holes, all of which are fixed by support plates located on the side and back, wherein the sieve hole diameter of the small-size block sieve plate is smaller than the sieve hole diameter of the medium-size block sieve plate."

[0004] It can be seen that the cited patent document has the problem that the silicon blocks with sharp shuttle angles easily cause clogging of the sieve holes. Utility Model Content

[0025] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0026] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0027] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0028] like Figures 1 to 6A silicon block sorting table shown in the figure includes a sorting box 1, a table 18 is arranged above the sorting box 1, and four supporting legs can be installed on the bottom surface of the table 18 to keep the table 18 above the sorting box 1. A feed port 17 for conveying crushed silicon blocks is installed on the top surface of the sorting box 1. The top surface of the feed port 17 penetrates through the top surface of the table 18. The staff can knock and crush the polysilicon on the surface of the table 18. After the crushing is completed, the silicon blocks can be pushed to the feed port 17, allowing the silicon blocks to enter the sorting box 1 through the feed port 17, and the crushed silicon blocks can be sorted.

[0029] The inner walls on both sides of the sorting box 1 are symmetrically installed with sieve plates 2 inclined downward. The two sieve plates 2 are arranged up and down. A plurality of sieve holes 13 are equidistantly provided on the top surface of the sieve plate 2. A guide plate 16 for conveying silicon blocks is connected to one end of the lower sieve plate 2 inclined downward. The guide plate 16 runs through one side of the sorting box 1. The silicon blocks entering the sorting box 1 through the feed port 17 will fall to the top surface of the sieve plate 2, so that the silicon blocks can move along the inclined surface of the top surface of the sieve plate 2, so that the silicon blocks smaller than the sieve holes 13 will pass through the sieve holes 13, and the silicon blocks larger than the sieve holes 13 will continue to move and then fall to the top surface of the sieve plate 2 below, so as to perform secondary sorting on the silicon blocks. After the sorting is completed, the silicon blocks will be discharged from the sorting box 1 along the guide plate 16.

[0030] Rectangular boxes 14 are respectively provided on the inner walls of both sides of the sorting box 1 and below the two sieve plates 2. The inner cavities of the two rectangular boxes 14 are both provided with collecting cabinets 15 for collecting silicon blocks. Silicon blocks that are smaller than the sieve holes 13 and pass through the sieve holes 13 will fall into the collecting cabinets 15, and the sorted silicon blocks can be collected.

[0031] A connection box 3 is installed on one side of the sorting box 1 and on one side of the two sieve plates 2. A cylinder 4 is fixedly installed on the inner wall of one side of the two connection boxes 3. The piston rod of the cylinder 4 is fixedly connected to the bottom plate 5. A vertical rod 6 is longitudinally installed on the top surface of the bottom plate 5. A sliding block 7 is provided on the peripheral sliding sleeve of the vertical rod 6. A lifting plate 8 is fixedly installed on the side of the sliding block 7 away from the cylinder 4. The lifting plate 8 is arranged between the sieve plate 2 and the collection cabinet 15. The two lifting plates 8 are also arranged at an inclined angle from top to bottom. The inclination directions of the two sieve plates 2 and the lifting plates 8 are arranged in opposite directions. A plurality of cones for ejecting silicon blocks are equidistantly installed on the top surface of the lifting plate 8. The number of the sieve holes 13 and the cone nails 9 is the same, and the aperture of the sieve holes 13 is the same as the diameter of the cone nails 9. The two side surfaces of the lifting plate 8 are in frictional contact with the inner walls of the two sides of the connection box 3, which can limit the lifting plate 8 and prevent the lifting plate 8 from rotating with the vertical rod 6 as the axis. By opening the cylinder 4, the cylinder 4 drives the bottom plate 5 to move, and the bottom plate 5 drives the slider 7 to move through the vertical rod 6, and then the slider 7 drives the lifting plate 8 to move, so that the lifting plate 8 can move from the inner cavity of the connection box 3 to the inner cavity of the sorting box 1, and the several cone nails 9 on the top surface of the lifting plate 8 can move to the corresponding sieve holes 13.

[0032] Two fixed boxes 10 are installed on one side of the sorting box 1 away from the two connecting boxes 3. Hydraulic cylinders 11 are fixedly installed on the bottom surfaces of the inner cavities of the two fixed boxes 10. The piston rods of the two hydraulic cylinders 11 are fixedly connected with concave blocks 12 for limiting the lifting plate 8. The two connecting boxes 10 and the two fixed boxes 3 are respectively connected to the sorting box 1. The length of the lifting plate 8 is the same as the width of the sorting box 1. When the lifting plate 8 moves to the inner cavity of the sorting box 1, one side of the lifting plate 8 will enter the inner cavity of the concave block 12, so that the concave block 12 limits the position of the lifting plate 8, so that when the two side surfaces of the lifting plate 8 just leave the inner walls on both sides of the connecting box 3, one side of the lifting plate 8 will enter the inner cavity of the concave block 12, so that the concave block 12 and the connecting box 3 can sequentially control the lifting plate 8. The lowering plate 8 is restricted. When one side of the lifting plate 8 moves to the inner cavity of the concave block 12, the lifting plate 8 will be directly below the sieve plate 2, and a plurality of cone nails 9 will be aligned with a plurality of sieve holes 13. At this time, the hydraulic cylinder 11 is turned on to drive the concave block 12 to move upward, so that the concave block 12 can drive the lifting plate 8 to move upward, and the lifting plate 8 will simultaneously drive the slider 7 to move upward around the vertical rod 6, so that the lifting plate 8 can drive a plurality of cone nails 9 to enter the inner cavity of the sieve hole 13, so that the cone nails 9 can push out the silicon blocks with sharp shuttle corners stuck in the inner cavity of the sieve hole 13, thereby solving the problem of blockage, reducing the problem that the silicon blocks with sharp shuttle corners are easy to cause blockage to the sieve hole 13 and need to be disassembled and cleaned, thereby improving the efficiency of silicon block sorting.

[0033] A transverse block adapted to the concave block 12 may be installed on one side of the lifting plate 8 facing the concave block 12, so that the transverse block can enter the inner cavity of the concave block 12, and the two side surfaces of the lifting plate 8 will be in the same longitudinal horizontal plane as the inner walls on both sides of the sorting box 1, and a groove for the slider 7 to move may be opened on the inner wall of the sorting box 1 facing the connection box 3, so that when the lifting plate 8 moves upward, the slider 7 can move upward in the inner cavity of the groove.

[0034] Working principle:

[0035] The silicon block sorting table places the polysilicon to be crushed on the surface of the table 18 and knocks and crushes it. After the crushing is completed, the silicon block is put into the feed port 17 and falls onto the surface of the sieve plate 2 through the feed port 17. The sieve plate 2 is inclined so that the silicon block can move along the surface of the two sieve plates 2 and be discharged through the guide plate 16, while the silicon block smaller than the sieve hole 13 will fall into the collection cabinet 15 for collection. When the silicon block with a sharp shuttle angle is stuck inside the sieve hole 13, the cylinder 4 is turned on to drive the lifting plate 8 to move through the bottom plate 5, the vertical rod 6 and the slider 7, so that the lifting plate 8 moves to the sieve hole 13. The lifting plate 8 is directly below the plate 2, and one side of the lifting plate 8 is allowed to enter the inner cavity of the concave block 12, so that several cone nails 9 can be aligned with several sieve holes 13. At this time, the hydraulic cylinder 11 is turned on, and the hydraulic cylinder 11 is allowed to drive the lifting plate 8 to move upward through the concave block 12, so that several cone nails 9 on the top surface of the lifting plate 8 can enter the sieve holes 13, so that the cone nails 9 can push out the silicon blocks stuck in the sieve holes 13, thereby solving the problem of the sieve holes 13 being blocked by the silicon blocks with sharp shuttle angles, reducing the problem that the sieve holes 13 are easily blocked by the silicon blocks with sharp shuttle angles and need to be disassembled and cleaned, thereby improving the efficiency of silicon block sorting.
