Description

Technical field:

[0001] The present invention relates to the technical field of silicon material recycling and processing, and in particular to a full-process automated processing technology for recycled materials. Background technology:

[0002] Recycled materials refer to reusable materials generated during the production process. Specifically, recycled materials refer to silicon materials, which are by-products or waste generated during the production of silicon materials, such as the silicon edge materials produced by slicing silicon rods. These materials can be reused after specific processing techniques to achieve the recycling of resources.

[0003] Existing recycled material processing process, such as Figure 1 As shown, after the operator takes the material, he / she signs and registers the material information, wipes the silicon mud on the surface of the silicon material with a reagent, rinses the silicon mud and puts it into a pallet box (material basket), pulls the pallet box to the loading end of the cleaning machine for loading, and then goes through the processing of reagent soaking, quick drain rinsing, pure water isolation, ultrasonic rinsing, and drying in the cleaning machine. The operator unloads the material and updates the information on the material tag at the same time. Then the material is pulled to the jaw crusher screening loading point for pre-crushing. The pre-crushed block material is put into the jaw crusher, and the crushed silicon material falls into the screening machine for screening. The operator sorts and boxes the screened silicon materials of different particle sizes, weighs and accurately mixes them, and finally stacks the material boxes, updates the information on the material tag, and pulls them into the warehouse.

[0004] In the above process, the operations of boxing, weighing, and fine mixing of the cleaned recycled materials mainly rely on manual operation, which has the following specific disadvantages: compared with automated mechanical operation, manual operation is slow and has limited processing capacity, and it is difficult to meet the needs of large-scale production. The operator's skill level and work attitude will affect the sorting effect, increasing the uncertainty in the production process. Manual material handling, packaging and other repetitive tasks are labor-intensive and easily lead to work fatigue. Therefore, the automated processing technology proposed in this application is to solve the above-mentioned shortcomings, improve efficiency, stability and safety through automated equipment and systems, reduce costs, and achieve higher quality material processing.
