Description

Technical Field

[0001] This utility model relates to the technical field of silicon material sorting equipment, specifically a silicon material crushing and sorting device. Background Technology

[0002] In the silicon material processing, crushing and sorting are two key steps. Existing silicon material crushing and sorting devices, such as those described in patent number 202123166383.4, include a main body, a feed hopper, a discharge pipe, and a crushing device installed inside the main body. This device feeds silicon material into the main body through the feed hopper, and uses the crushing device to crush and screen the silicon material. The lower end face of the main body is funnel-shaped, allowing for complete discharge of the crushed silicon material, thus improving the device's practicality. However, this existing technology still has some shortcomings.

[0003] First, the existing equipment has limited crushing efficiency. While its crushing device can perform initial crushing of silicon material, it is not thorough enough for larger particles, requiring additional crushing during subsequent screening, increasing workload and time costs. Second, the screening function of the existing equipment is inadequate. Screening relies mainly on screens, but these screens are easily clogged by silicon material, especially when processing damp or small-particle silicon, where the screen openings are easily blocked, affecting screening efficiency.

[0004] In view of the problems existing in the prior art, this utility model proposes an improved silicon material crushing and sorting device, which aims to solve the problems of limited crushing effect and imperfect screening function in the prior art. Utility Model Content

[0014] (III) Beneficial Effects This utility model provides a silicon material crushing and sorting device, which has the following beneficial effects: 1. This utility model, by setting up multiple crushing and scraping components, in conjunction with a second motor driving the connecting rod to rotate, causes the crushing and scraping components to reciprocate along the circumferential direction within the annular cavity of the filter screen. The crushing rollers in the crushing components are threadedly connected to the shaft via reciprocating threads, enabling them to reciprocate axially when the shaft rotates, thereby crushing the silicon material in the filter screen from all directions. This multi-directional crushing method effectively solves the problem of incomplete crushing in existing technologies, ensuring that the silicon material is fully crushed and improving the crushing effect. Simultaneously, the guide plate in the scraping component can concentrate the silicon material in the filter screen into the area that the crushing rollers can reach, further improving the crushing efficiency.

[0015] 2. The filter screen of this utility model has a unique design, consisting of a fixed part, a recessed part, and a raised part. Multiple crushing and scraping components are installed within the annular cavity of the recessed part. During the screening process, the second motor drives the connecting rod to rotate, causing the crushing and scraping components to reciprocate along the circumference of the annular cavity. Simultaneously, the rollers reciprocate axially on the shaft, crushing the silicon material in the filter screen while also vibrating the screen to prevent clogging. Furthermore, the outer periphery of the filter screen is fixedly connected to the inner wall of the outer cylinder by multiple springs. This elastic connection allows the filter screen to generate slight vibrations during the crushing process, further improving screening efficiency and ensuring that the silicon material can pass smoothly through the screen holes, thus solving the problem of imperfect screening function in existing technologies.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0021] Example 1, please refer to Figures 1 to 5The present invention provides a technical solution: a silicon material crushing and sorting device, comprising an outer cylinder 1, a crushing component, and a screening component, wherein the crushing component is installed on the top wall of the outer cylinder 1.

[0022] A support plate 7 is fixedly connected to the inner wall of the outer cylinder 1. The support plate 7 is circular in shape. Its main function is to provide stable support for the filter screen 6, ensuring that the filter screen 6 can maintain a fixed position during operation, and at the same time provide a basic platform for the installation and operation of the screening components.

[0023] The screening component includes a filter screen 6, a connecting rod 5, multiple crushing components, and multiple scraping components. The filter screen 6 consists of a fixed part, a recessed part, and a raised part, arranged from circumference to center. This unique structural design allows the filter screen 6 to better adapt to the crushing and screening requirements of silicon material during the screening process. The fixed part of the filter screen 6 is placed on the support plate 7. Numerous mesh holes are formed on the recessed end wall of the filter screen 6. These mesh holes are the key parts for silicon material screening, and the crushed silicon material is screened and separated through the mesh holes. Furthermore, the recessed part of the filter screen 6 forms an annular cavity, and the interior of the raised part of the filter screen 6 is hollow.

[0024] The connecting rod 5 is rotatably mounted on the protrusion of the filter screen 6. Each crushing and scraping component is placed within the annular cavity of the recessed portion of the filter screen 6. The connecting rod 5 is driven by each crushing and scraping component, and when the connecting rod 5 rotates, it drives each crushing and scraping component to reciprocate along the circumference of the annular cavity. The screening component also includes a second motor 8, which is fixedly mounted below the protrusion of the filter screen 6. The second motor 8 is driven by the connecting rod 5, and drives the connecting rod 5 to rotate.

[0025] The recessed portion forms an annular cavity, providing space for the installation and movement of the crushing and scraping components. The lower part of the protrusion is also hollow, used to install other transmission components. The main function of the connecting rod 5 is to transmit the power of the second motor 8 to the crushing and scraping components, driving them to reciprocate along the circumference of the annular cavity, thereby achieving the crushing and screening operation of the silicon material in the filter screen 6. When the connecting rod 5 rotates, it can drive each crushing and scraping component to reciprocate along the circumference of the annular cavity, achieving all-round crushing and screening of the silicon material. The second motor 8 is the power source of the screening components. It drives the connecting rod 5 to rotate through the transmission connection, thereby driving the crushing and scraping components to work and achieve the function of crushing and screening the silicon material.

[0026] Specifically, the compaction assembly includes a gantry frame 9, a shaft 10, and a roller 11. The gantry frame 9 is located in the annular cavity of the recessed portion of the filter screen 6, and is fixedly connected to the connecting rod 5. The shaft 10 passes through the roller 11 and the two are rotatably connected. Both ends of the shaft 10 are fixedly connected to the gantry frame 9.

[0027] The gantry frame 9 primarily serves to provide mounting and support for the shaft 10 and the grinding roller 11. The grinding roller 11 is a key component of the crushing assembly; through its rotatable connection to the shaft 10, it reciprocates axially under the drive of the connecting rod 5, crushing the silicon material in the filter screen 6. This design effectively improves the crushing effect, ensuring that the silicon material is fully crushed.

[0028] More specifically, the outer wall of the shaft 10 is engraved with a reciprocating thread 13, and the roller 11 is threadedly connected to the shaft 10 through the reciprocating thread 13.

[0029] The reciprocating thread 13 is an innovation of this invention, enabling the grinding roller 11 to reciprocate axially as the shaft 10 rotates. This reciprocating movement allows the grinding roller 11 to fully contact the silicon material in the filter screen 6, achieving all-around crushing and effectively solving the problem of incomplete crushing in the prior art, thus improving the crushing effect.

[0030] Specifically, the scraping assembly includes two guide plates 12, which are placed flat in a V-shape within the annular cavity of the recessed portion of the filter screen 6. A gap exists between the two guide plates 12, located in the center of the annular cavity of the recessed portion of the filter screen 6. One side edge and the lower edge of each guide plate 12 abut against the filter screen 6. The two guide plates 12 are fixedly connected to the connecting rod 5.

[0031] The main function of the guide plate 12 is to concentrate the silicon material in the filter screen 6 into the area that the roller 11 can crush. At the same time, it turns the silicon material over during the movement to prevent silicon material from accumulating and improve crushing efficiency. The figure-eight design allows the guide plate 12 to better guide the movement direction of the silicon material, ensuring that the silicon material can be evenly distributed in the filter screen 6, further improving the crushing effect.

[0032] More specifically, the screening component also includes a rotating shaft and a conical block 4. The rotating shaft passes through the filter screen 6 and the connecting rod 5 from bottom to top. The rotating shaft is rotatably connected to the filter screen 6 and fixedly connected to the connecting rod 5. The output shaft of the second motor 8 is connected to the rotating shaft for transmission. The upper end of the rotating shaft is fixedly connected to the conical block 4.

[0033] The main function of the conical block 4 is to guide the crushed silicon material smoothly into the filter screen 6. Simultaneously, driven by the second motor 8, the conical block 4 generates mechanical vibration, further improving screening efficiency. The design of the rotating shaft allows the conical block 4 and the connecting rod 5 to rotate synchronously, ensuring the coordinated operation of the entire screening component.

[0034] Specifically, the crushing component includes a crushing box 2, a first motor 3, and two crushing rollers. The crushing box 2 is fixedly installed on the top wall of the outer cylinder 1 and the two are connected. The first motor 3 is fixedly installed on the outer side wall of the crushing box 2. The two crushing rollers are installed side by side and rotate inside the crushing box 2, and the crushing teeth on the two crushing rollers mesh with each other. The first motor 3 is connected to the two crushing rollers respectively, and the first motor 3 drives the two crushing rollers to rotate in opposite directions.

[0035] The primary function of the crushing component is to initially crush the input silicon material, providing suitable particle size for subsequent screening operations. The counter-rotating design of the two crushing rollers effectively improves crushing efficiency, ensuring that the silicon material is fully crushed before entering the screening component. The first motor 3 drives the two crushing rollers to rotate after starting.

[0036] In operation, the first motor 3 and the second motor 8 are started first. Silicon material is fed into the crushing chamber 2, and the first motor 3 drives the two crushing rollers to rotate in opposite directions, performing initial crushing of the silicon material. The crushed silicon material falls onto the conical block 4 and slides down into the filter screen 6 under the guidance of the conical block 4. At this time, the rotation of the second motor 8 drives the conical block 4 to rotate, making it easier for the silicon material on the conical block 4 to fall into the filter screen 6.

[0037] Simultaneously, the rotation of the second motor 8 drives the connecting rod 5 to rotate, which in turn drives the guide plate 12 and the gantry frame 9 to perform circular motion. Since the grinding roller 11 is in contact with the bottom surface of the filter screen 6, the circular rotation of the gantry frame 9 causes the grinding roller 11 to rotate around the shaft 10. The friction between the grinding roller 11 and the bottom surface of the filter screen 6 in the perpendicular direction is used to crush the silicon material in the filter screen 6. At the same time, the rotation of the grinding roller 11 allows it to reciprocate on the shaft 10 via a ball screw pair, thereby achieving the crushing of the silicon material through friction between the grinding roller 11 and the bottom surface of the filter screen 6 in the direction parallel to the axis, thus improving the crushing effect.

[0038] When the guide plate 12 makes a circular motion, since it is at a certain angle to both the outer and inner edges of the inner wall of the filter screen 6, the movement of the guide plate 12 can turn the silicon material in the filter screen 6 over, and at the same time, concentrate the silicon material near the inner and outer edges of the filter screen 6 to the place that the roller 11 can crush.

[0039] Example 2, please refer to Figure 6 The main difference between this embodiment and Embodiment 1 is that: multiple springs 15 are fixedly connected to the inner wall of the outer cylinder 1, and the springs 15 are arranged in a circular array. A fixing block 14 is fixedly connected to the end of each spring 15 away from the outer cylinder 1. The outer periphery of the filter screen 6 is fixedly connected to each fixing block 14.

[0040] The design of spring 15 and fixing block 14 provides elastic support for filter screen 6. During the crushing process, filter screen 6 will generate a certain amount of vibration. This elastic support can effectively buffer the vibration and prevent filter screen 6 from being damaged due to excessive vibration. At the same time, the elasticity of spring 15 can also cause filter screen 6 to produce a small displacement during vibration, further improving screening efficiency and ensuring that silicon material can pass smoothly through the screen holes.
