Description

A silicon material water quenching equipment feeding structure TECHNICAL FIELD

[0001] The patent relates to the technical field of polycrystalline silicon equipment, in particular to a silicon material water quenching equipment feeding structure. BACKGROUND

[0002] With the continuous expansion of the application field of electronic-grade polycrystalline silicon, the requirement for its product quality is also getting higher and higher. The metal impurity content in electronic-grade polycrystalline silicon has become one of the important indicators for evaluating the product quality, because the high or low of the content directly affects the quality of downstream wafer manufacturing products. Therefore, it is crucial to control the metal impurity content in the manufacturing process of electronic-grade polycrystalline silicon, which also promotes the research and application of polycrystalline silicon crushing technology in controlling metal pollution.

[0003] The process mode of silicon material crushing has developed from the previous artificial crushing, jaw crushing, roller crushing and other crushing forms to the current water quenching crushing. During the water quenching crushing process of the silicon material, hidden cracks may exist in the silicon rod cross section during the manual cutting and feeding process, and more or less blocky silicon material may fall off during the transfer process, resulting in mechanical structure jamming during the water quenching feeding process. During the manual cutting and feeding process, the silicon rod length deviation, and the water quenching feeding table needs to meet the feeding of silicon materials of different lengths, thereby causing frequent failures of the feeding table and affecting the crushing capacity.

[0004] The existing feeding structure mainly includes a shell, a moving device and a support device. The moving device is installed in the shell, the support device is installed on the upper part of the shell, the moving device is connected to the support device, and the support device includes a fixed support and a jacking support. The jacking support is installed on the upper part of the fixed support, and the jacking support lifts the silicon material and feeds it through a motor or a cylinder. However, during the feeding process, due to the dense support device, part of the silicon material that falls off during the feeding process may be stuck in the gap between the jacking support and the fixed support, causing the support device to be stuck. At the same time, silicon powder may be generated due to the friction between the silicon materials, and the silicon powder may fall on the moving device inside the shell under the action of gravity, causing wear of the cylinder or sliding block structure, thereby increasing the failure rate of the device.

[0005] Therefore, the patent embodiment provides a silicon material water quenching equipment feeding structure, which mainly aims to provide a silicon material water quenching equipment feeding structure that reduces the failure rate of the device.
