Description

Technical Field

[0001] This utility model relates to the field of silicon material processing technology, and in particular to a multi-stage linkage hammer crushing device for silicon material crushing. Background Technology

[0002] Silicon is a core raw material for the photovoltaic and semiconductor industries. During production, large blocks of silicon often need to be crushed into small particles and powder to meet the needs of subsequent processes. With the rapid growth of photovoltaic installations, the consumption of silicon is enormous. Crushing efficiency and cost directly affect the economics of the photovoltaic industry chain. Crushing block silicon into uniform particles can improve the utilization rate of silicon in the ingot casting and crystal pulling stages, reduce waste, and at the same time, the scraps and waste generated by the photovoltaic and semiconductor industries can be reused after crushing and purification, reducing raw material costs and environmental pollution. Existing silicon crushing methods include jaw crushing, which uses the squeezing and shearing action of the moving jaw and the fixed jaw to crush silicon, suitable for coarse crushing of large blocks of silicon; hammer crushing, which uses high-speed rotating hammers to impact silicon and cause it to collide with the liner to crush it, suitable for medium and fine crushing; and ultrasonic crushing, which uses the cavitation effect generated by ultrasonic vibration to create microcracks inside the silicon and gradually expand them, suitable for the preparation of micron-sized silicon powder.

[0003] Hammer crushing requires a multi-stage linkage hammer crushing device to crush silicon material. During the crushing process, a large amount of dust is generated. Existing technologies mostly use a fully enclosed metal sealing cover to install around the crushing chamber, and use rubber sealing strips or silicone sealing rings to fill the joints to prevent dust from being directly emitted. However, when feeding is required, the metal sealing cover must be manually moved open, the material added into the crushing device, and then the metal sealing cover is replaced before starting the device to crush. The operation process is relatively cumbersome, resulting in reduced production efficiency and decreased practicality. Utility Model Content

Then, by pulling the limiting plate upward, the cover can be opened by rotating along the second rotating shaft, thereby cleaning the inner wall of the dust collection box, achieving the purpose of rapid dust collection, improving practicality and reducing production pollution.

[0038] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 5The crushing mechanism 4 includes a rotating column 401, which is rotatably connected to the inner wall of the hollow protective shell 1. Multiple hammer teeth 402 are fixedly connected to the outer wall of the rotating column 401. A pulley 403 is fixedly connected to the left end of the rotating column 401. A transmission belt 404 drives the adjacent pulleys 403. The limiting assembly 304 includes a fixing block 3043. The hammer teeth 402 can effectively perform hammering operations. The function of the pulleys 403 is to transmit power through the multiple adjacent pulleys 403. The drive belt 404 is used to transmit and distribute power.

The function of the fixed block 3043 is to limit the range of motion of the rotating column 401 and ensure that it rotates within a predetermined path, thereby improving the stability and reliability of the entire device. The fixed block 3043 is fixedly connected to the front side of the cover plate 3032. The inner wall of the fixed block 3043 is slidably connected to the pin 3042. The top of the pin 3042 is fixedly connected to the limit plate 3041.

[0039] Specifically, the hollow protective shell 1 ensures its stability and safety during operation, the hammer teeth 402 play a crucial role in crushing materials, the pulleys 403 are connected to each other by the transmission belt 404, the fixing block 3043 is fixed to the front end of the cover plate 3032 to ensure the stability of the limiting component 304, and the limiting plate 3041 not only ensures the precise control of the crushing mechanism 4 during operation, but also provides the operator with convenient adjustment means, making the whole crushing process more efficient and safer.

[0040] Please see the appendix Figure 3 Appendix Figure 4 and attached Figure 6 The positioning component 203 includes a stop plate 2032, which is fixedly connected to the outer wall of the rotating shaft 201. Multiple fixing rods 2031 are fixedly connected to the left side of the hollow protective shell 1 near the edge. The drive mechanism 5 includes a bracket 502, which is fixedly connected to the bottom left side of the hollow protective shell 1. The fixing rods 2031 can provide stable support to ensure that the hollow protective shell 1 remains in its position under various operating conditions. The bracket 502 is fixedly installed in the bottom left area of ​​the hollow protective shell 1 to ensure the fixed connection between the drive mechanism 5 and the hollow protective shell 1, thereby providing necessary support and stability during the drive process. An asynchronous motor 501 is fixedly connected to the inner wall of the bracket 502.

[0041] Specifically, the abutment 2032 is fixed on the outer wall of the rotating shaft 201, ensuring the stability and reliability of the device. The fixing rod 2031 is firmly connected in the corresponding position. The bracket 502 is fixed on the bottom left side of the hollow protective shell 1. Taking into account the maximization of space utilization and the stability of the structure, the asynchronous motor 501 not only improves the operating efficiency of the device, but also ensures its stable performance in various working environments.

[0042] Working principle: When silicon material is fed into the hollow protective shell 1 for crushing, the silicon material extrusion baffle 202 causes the rotating shaft 201 to be squeezed and rotated, which in turn drives the gear 206 to rotate synchronously. This allows the rack 205 to slide outward in the guide rail 204, thereby squeezing the sliding column 2073. This causes the spring 2072 to slide into the hollow tube 2071, completely opening the baffle 202 downward. When the material feeding is finished, the downward pressure on the baffle 202 disappears, and the spring 2072 releases its elastic potential energy, thereby pushing the sliding column 2073 to move the rack 205 inward. This, in turn, drives the gear 206 to rotate in the opposite direction, causing the rotating shaft 201 to rotate and close the baffle 202. At the same time, the rotation angle of the rotating shaft 201 is limited by the contact between the abutment plate 2032 and the fixing rod 2031, preventing the baffle 202 from flipping upward.

[0043] When the silicon material is crushed inside the hollow protective shell 1, a large amount of dust will be generated. At this time, the vacuum pump 302 is started to extract the air from the connecting pipe 305, thereby creating a vacuum inside the dust collection box 301. Then, the dust inside the hollow protective shell 1 is filtered by the first filter plate 306 to prevent the finished product from entering the dust collection box 301. It then enters the dust collection box 301 along the guide plate 308 and is isolated on the outer wall of the connecting pipe 305 by the second filter plate 307. After the processing is completed, the pin 3042 is pulled upward to unlock the position of the fixing block 3043. Then, the cover plate 3032 is rotated to open the inner wall of the dust collection box 301 and clean the dust inside.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
