Description

Technical Field

[0001] This utility model relates to the field of building concrete waste recycling technology, and in particular to a building concrete waste recycling device. Background Technology

[0002] Building concrete scrap recycling technology is a key technology for achieving green construction and resource recycling in the construction industry. It systematically processes leftover concrete, waste test blocks, and casting waste generated during construction to achieve material reuse. The technology process mainly includes four stages: scrap collection, graded treatment, recycling, and secondary application. In the collection stage, scrap is collected at designated locations using special containers to reduce on-site pollution. Graded treatment separates scrap into plastic scrap and hardened waste according to its state, and different processes are used for each. In the recycling stage, impurities are removed by crushing, screening, and washing. Hardened waste is made into recycled aggregate, while plastic scrap can be directly used for casting secondary components after adjusting the mix ratio. The recycled aggregate can be used to prepare mortar, subbase concrete, and filler for municipal engineering. The cement component in the scrap can also be partially reused after treatment.

[0003] During construction, concrete waste is generated when the building is in use and needs to be recycled. However, in existing concrete waste recycling processes, some iron material gets stuck in the screen mesh during screening. This material remains on the screen surface, clogging the screen holes and preventing sand and gravel aggregates from passing through smoothly. Ultimately, this leads to severe screen wear, shortens the screen's service life, increases equipment load, and reduces screening efficiency. Utility Model Content
