[0023] Example

[0024] Reference Figure 1-4 This is an embodiment of the present invention, which provides a crushing and screening device for polysilicon waste, comprising:

[0025] The frame includes a fixed frame 101, a crushing assembly 102 fixedly installed at the end of the fixed frame 101, a fixing assembly 103 fixedly installed on the side surface of the fixed frame 101, a vibration assembly 104 snapped into the bottom of the fixing assembly 103, and a screening assembly 105 used in conjunction with the vibration assembly 104.

[0026] The crushing assembly 102 includes a drive motor 102a adapted to be mounted on the surface of the fixed frame 101, a pulley assembly 102b used in conjunction with the drive motor 102a, and an operation box 102c fixedly mounted on the side surface of the pulley assembly 102b.

[0027] The crushing assembly 102 also includes a feed port 102d located in the center of the control box 102c, a first crushing roller 102e fixedly installed at the output end of the pulley assembly 102b, and a second crushing roller 102f used in conjunction with the first crushing roller 102e.

[0028] Specifically, waste material enters the crushing assembly 102 through the feed port 102d of the control box 102c. The drive motor 102a drives the first crushing roller 102e and the second crushing roller 102f to rotate in opposite directions through the pulley group 102b, which powerfully crushes the material. The crushed material falls to the screening assembly 105, and the vibration motor 105b drives the screen plate 105c to vibrate regularly, realizing particle classification. The spring 104c and the limit frame 104e of the vibration assembly 104 effectively buffer the vibration impact and ensure stable operation of the equipment. This achieves continuous processing from crushing to screening, improving the recycling efficiency of polysilicon waste.

[0029] The fixing assembly 103 includes a connecting rod 103a fixedly connected to the side wall of the fixing frame 101, a connecting frame 103b fixedly installed at the bottom of the connecting rod 103a, and a fixing pin 103c inserted into the side surface of the connecting frame 103b.

[0030] The vibration assembly 104 includes a rod 104a sleeved on the side surface of the connecting frame 103b, a baffle 104b sleeved on the side surface of the rod 104a, and a spring 104c sleeved on the outer surface of the rod 104a.

[0031] The vibration assembly 104 also includes a base plate 104d fixedly connected to the bottom of the boom 104a, a limiting frame 104e fixedly installed at the bottom of the baffle 104b, and a connecting hook 104f snapped into the bottom of the limiting frame 104e.

[0032] The screening assembly 105 includes a placement frame 105a, a vibration motor 105b adapted to be installed on the side surface of the placement frame 105a, and a screen plate 105c fixedly connected to the end of the placement frame 105a. The screen plate 105c is fixedly connected to the output end of the vibration motor 105b.

[0033] It should be noted that the fixing component 103 provides stable support for the equipment through the connecting rod 103a and the connecting frame 103b, and the fixing pin 103c ensures that all components are firmly connected. When the crushed material falls to the screening component 105, the vibrating motor 105b drives the screen plate 105c to generate high-frequency vibration. At the same time, the spring 104c and baffle 104b structure of the vibrating component 104 effectively buffer the vibration impact. The suspension system composed of the hanging rod 104a and the bottom plate 104d keeps the screen plate 105c running smoothly, and the limit frame 104e and the connecting hook 104f further stabilize the overall structure. Under the action of vibration, the screen plate 105c achieves accurate material classification, completes the continuous processing flow from crushing to screening, and ensures the high efficiency and stability of polysilicon waste recycling.

[0034] In operation, the drive motor 102a drives the pulley group 102b to drive the double crushing rollers to rotate in opposite directions to achieve efficient crushing; the connecting frame 103b and the connecting rod 103a of the fixed component 103 form a rigid support structure, which, together with the fixing pin 103c, ensures the overall stability of the equipment; the vibration component 104 adopts a combination of spring 104c suspension system and limit frame 104e to effectively buffer the vibration impact during the screening process; the vibration motor 105b directly drives the screen plate 105c to generate high-frequency vibration, realizing accurate material classification; the various functional modules work together to form a continuous processing flow, and the crushed material is automatically classified by the screening component 105 to meet the process requirements of polysilicon waste recycling.

[0035] In summary, the dual crushing roller design achieves efficient crushing and ensures uniform particle size of the material; the vibration component 104 adopts a combination structure of spring 104c for shock absorption and limit frame 104e to effectively control the vibration amplitude during the screening process; the screening component 105 is integrated with the crushing system to form a continuous automated processing flow; the rigidity is enhanced by connecting rod 103a and fixing pin 103c to adapt to the requirements of high hardness material processing; the vibration motor 105b directly drives the screen plate 105c to improve screening efficiency while reducing energy consumption.
