Detailed Description
The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.
In the following description, the terms "left", "right", "upper", "lower", "front", "rear", "inner" and "outer" are relative terms, and are not intended to be exhaustive.
An automated production line for crystalline silicon, referring to fig. 1, comprises a crusher 1. The outlet of the crusher 1 is communicated with the inlet of the climbing conveyor 4. The outlet of the climbing conveyor 4 is communicated with the inlet of the three-stage linear vibration screening machine 2. The three-stage linear vibration screening machine 2 can screen three size ranges of crystals at a crystalline silicon position, and is provided with a first outlet 21, a second outlet 22 and a third outlet 23. The three outlets correspond to three size ranges of crystalline silicon, respectively. The first outlet 21 is communicated with the feed inlet of the first magnetic separator 3. The second outlet 22 is communicated with the feed inlet of the second magnetic separator 3. The third outlet 23 is communicated with the feed inlet of the climbing magnetic separation conveyor 6. The discharge port of the climbing magnetic separation conveyor 6 is communicated with the feed port of the circular vibrating screen 5. The crusher 1, the three-stage linear vibration screening machine 2, the magnetic separator 3 and the circular vibration screen 5 are provided with dust removal openings 7, and the dust removal openings 7 are communicated with one another and are provided with dust removal pipes 8.
And pouring the crystalline silicon raw material into a feeding port of the crusher 1, crushing the silicon material by the crusher 1, and crushing the block-shaped silicon material with a certain shape to obtain the required small blocks and powdery silicon material. Because the three-stage linear vibration screening machine 2 has a certain height, small blocks and powdery silicon materials obtained by crushing are lifted by the climbing conveyor 4 and conveyed to the three-stage linear vibration screening machine 2 for screening. The three-stage linear vibration screening machine 2 screens the crushed silicon materials, screens the silicon materials with different specifications according to the set specification requirements, and obtains finished crystalline silicon with different sizes. Since any magnetic substance is not allowed to exist in the crystalline silicon, the crystalline silicon with qualified size reaches the magnetic separator 3 through the first outlet 21 and the second outlet 22, and the magnetic substance is removed from the crystalline silicon. And crystalline silicon of unequal size passes through the third outlet 23 to the climbing magnetic separator conveyor 6. The function of the climbing magnetic separation conveyor 6 is the same as that of a common magnetic separator, and the main difference is that the climbing needs to be lifted, and the silicon material to be magnetically separated is lifted to the feeding port of the circular vibrating screen 5 in the next procedure. The circular vibrating screen 5 screens the specific materials after screening by the screening machine, and performs screening operation again to meet the specific needs of users.
Further developments of the utility model can be further extended from the above-described embodiments, providing a plurality of novel embodiments.
As a second embodiment of the present utility model, referring to fig. 2 to 4, based on embodiment 1, the inner wall of the dust removing port 7 is provided with an annular groove 71, and the upper end of the dust removing port 7 is provided with two oppositely arranged notches 72. The notch 72 communicates with the annular groove 71. Two sealing plates 73 are arranged at the lower end of the dust removal port 7. Torsion spring seats 74 are rotatably arranged on the front side and the rear side of the sealing plate 73. Torsion spring seats 74 are provided on the inner wall of the device. In a normal state of the torsion spring seat 74, the two seal plates 73 abut against each other, thereby sealing the dust removing port 7.
The side wall of the dust removing pipe 8 is provided with a positioning block 81. The positioning blocks 81 are matched with the notches 72 in number and position and matched with the notches 72 and the annular groove 71 in shape.
When the dust removing opening 7 is required to be provided with the dust removing pipe 8, the dust removing pipe 8 is inserted into the dust removing opening 7, the positioning block 81 is inserted into the corresponding notch 72, the dust removing pipe 8 pushes the sealing plate 73 open, the dust removing pipe 8 is rotated, and the dust removing pipe 8 is firmly connected with the dust removing opening 7. When the dust removing pipe is taken down, only the dust removing pipe 8 is required to be rotated, so that the positioning block 81 is moved to the notch 72, the dust removing pipe 8 can be directly taken down, and the two sealing plates 73 reseal the dust removing port 7 on the basis of the restoring force of the torsion spring seat 74.
The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art.
