Description

Technical Field

[0001] The utility model relates to the technical field of silicon material recovery, in particular to a silicon material magnetic separation and screening integrated operating table. Background Art

[0002] With the widespread application of silicon materials in electronics, optoelectronics, solar energy and other fields, the recycling of silicon resources has gradually received attention. The recycled silicon scraps contain metal or magnetic impurities, which can cause defects in silicon wafers and seriously affect the efficiency of silicon wafer cells.

[0003] There is a silicon material screening station on the market, which is mainly provided with a cushion layer under the cover plate, and a plurality of placement holes in a rectangular array are opened on the cushion layer, and a magnet is fixedly installed in each placement hole. The metal impurities and magnetic substances in the silicon material to be screened evenly spread on the cover plate are first separated from the silicon material by magnets, and then the sorting personnel sort out the silicon material with separated metal impurities and magnetic substances from the cover plate layer by layer. Although this screening method can efficiently screen out the metal impurities and magnetic substances in the silicon material to be screened, the silicon material with separated metal impurities and magnetic substances still needs to be manually sorted layer by layer, resulting in poor efficiency of silicon material screening. In addition, after the metal impurities and magnetic substances are screened out, there are still a large number of broken materials in the silicon material that have not been screened out, which not only increases the screening process but also may cause secondary pollution of the silicon material to be screened.

[0044] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0045] As Figure 1 - Figure 2 shown, the embodiment of the present utility model provides a comprehensive operation table for magnetic separation and screening of silicon materials, including: a bottom frame 1, a load-bearing panel 2, a sliding assembly, a screening assembly, a filter screen 7, a collection assembly, a motor 6, and other parts.

[0046] Among them, a load-bearing panel 2 is fixedly arranged on the top of the bottom frame 1 for carrying the silicon materials to be screened, that is, the recycled materials and other components. A sliding assembly is arranged in the Y-axis direction of the load-bearing panel 2, and a screening assembly is arranged on the sliding assembly. The sliding assembly reciprocates along the Y-axis direction of the load-bearing panel 2 under the drive of the motor 6. The reciprocating sliding assembly drives the screening assembly to move, and the moving screening assembly repeatedly screens the impurities in the recycled materials. A filter screen 7 is arranged on the load-bearing panel 2, and the filter screen 7 can screen and separate the crushed materials on the load-bearing panel 2. In order to separate the screened impurities for convenient centralized treatment, a collection assembly is also arranged on the load-bearing panel 2.

[0047] During use, first place the recycled material on the load-bearing panel 2 and gently spread it out evenly. Then start the motor 6. The motor 6 drives the sliding assembly to move reciprocally. The reciprocally moving sliding assembly drives the screening assembly to move. The moving screening assembly fully screens the impurities and silicon material. Then, the broken materials in the recycled material are screened out through the filter net 7. The screened impurities and broken materials enter the collection assembly for separation. Finally, the impurities in the collection assembly are centrally processed.

[0048] Specifically, a load-bearing panel 2 is fixedly arranged on the top of the chassis 1. The load-bearing panel 2 is in a cuboid structure. Placement grooves 21 are respectively and penetratively opened at positions adjacent to the opposite side walls of the load-bearing panel 2 in the Y-axis direction of the load-bearing panel 2.

[0049] The sliding assembly includes: a lead screw module 31, an adjusting block 32, a support rod 33, and a sliding member 34. Among them, the lead screw module 31 is arranged in the Y-axis direction of the load-bearing panel 2, that is, on one side wall of the load-bearing panel 2 along the Y-axis direction. The adjusting block 32 is arranged on the slider of the lead screw module 31. The adjusting block 32 can reciprocally move along the Y-axis direction of the load-bearing panel 2 driven by the lead screw module 31. The support rod 33 is arranged on the other side wall of the load-bearing panel 2 relative to the lead screw module 31. A sliding member 34 is arranged on the side wall of the support rod 33 far from the load-bearing panel 2. The sliding member 34 can reciprocally move along the support rod 33. The adjusting block 32 and the sliding member 34 can be adjusted in height according to the size of the recycled material, and the maximum height adjustment degree ≤ 50 mm.

[0050] The screening assembly includes: a placement frame 41 and magnetic blocks 42. Among them, the placement frame 41 is in a "one" shape. One end of it is arranged on the adjusting block 32, and the other end is arranged on the sliding member 34. The placement frame 41 is located above the load-bearing panel 2. The placement frame 41 can reciprocally move above the load-bearing panel 2 driven by the adjusting block 32 and the sliding member 34. By adjusting the heights of the adjusting block 32 and the sliding member 34, the placement frame 41 located above the load-bearing panel 2 can be in the optimal height. Further, the placement frame 41 is made of acrylic material with relatively high strength. A number of magnetic blocks 42 are fixedly installed in the placement frame 41. The number of magnetic blocks 42 is arranged in a row. Similarly, driven by the placement frame 41, the magnetic blocks 42 can also reciprocally move above the load-bearing panel 2, so as to realize the full separation of the metal or magnetic impurities in the recycled material on the load-bearing panel 2 from the silicon material.

[0051] The filter net 7 is fixedly arranged in the placement groove 21. Its shape is funnel-shaped. The filter net 7 can screen out the broken materials smaller than 3 mm on the load-bearing panel 2.

[0052] The collecting assembly includes a groove part 5 and a material receiving pipe (not shown in the figure). The groove part 5 is arranged in the X-axis direction of the load-bearing panel 2, that is, on one side wall of the load-bearing panel 2 along the X-axis direction. One end of the groove part 5 contacts the end of the screw module 31, and the other end contacts the end of the support rod 33. The groove bottom 51 of the groove part 5 extends downward along the vertical direction of the load-bearing panel 2, and the groove wall 52 of the groove part 5 is flush with the load-bearing panel 2. The separated metal or magnetic impurities are transported to the groove part 5 through the magnetic block 42, and finally the impurities in the groove part 5 are uniformly processed. The material receiving pipe is fixedly arranged at the bottom of the load-bearing panel 2, below the filter screen 7, and is used to collect and screen the separated fragments smaller than 3 mm.

[0053] Finally, in order to enable the screw module 31 to reciprocate along the Y-axis direction of the load-bearing panel 2, a motor 6 is also provided on the operating table. The output end of the motor 6 is transmission-connected to the screw module 31. The rotation of the motor 6 drives the screw module 31 to reciprocate along the Y-axis direction of the load-bearing panel 2. The screw module 31 drives the adjustment block 32 to reciprocate. The adjustment block 32 drives the placement frame 41 and the magnetic block 42 to reciprocate along the Y-axis direction of the load-bearing panel 2. The reciprocating magnetic block 42 continuously absorbs metal or magnetic impurities, thereby achieving the purpose of fully screening the impurities in the recycled material.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
