Concrete excess material recycling treatment system

Abstract

The invention relates to a concrete excess material recycling treatment system which comprises an excess material collecting device, a sand-stone separating device, a drying device, a ball milling device and a slurry treatment device, and the excess material collecting device is arranged on the upper portion of the sand-stone separating device and used for collecting concrete excess materials. Theslurry treatment device is arranged below the sand-stone separating device and used for treating separated slurry, the drying device is connected to one side of the sand-stone separating device and used for drying separated stones, and the ball milling device is connected to one side of the drying device and used for carrying out surface ball milling treatment on the dried stones. The stones aredried and then subjected to ball-milling treatment, so that adhered substances on the surface are removed, and accordingly the quality of separated aggregates is improved. The concrete excess materialrecycling treatment system has the effect of improving the quality of the aggregates separated from the concrete excess materials.

Description

technical field [0001] The present application relates to the technical field of concrete, in particular to a recycling and processing system for residual concrete. Background technique [0002] Concrete is an indispensable material in civil engineering. It is a mixture made of cement, granular aggregates, water, chemical admixtures and mineral admixtures that need to be added in an appropriate proportion; after use, due to The remaining concrete left in the mixer and in the transportation equipment, including stones, sand and cement in the remaining materials, is usually not utilized, which wastes construction resources and high construction costs. [0003] At present, the recycling of concrete residues is to separate the sand and gravel from the slurry through the separation equipment, and the separated sand and gravel are used again as concrete aggregates for secondary use, and the separated mortar is discharged into the sedimentation tank, and the upper layer of wastewat...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: some plasticizers such as cement adhere to the surface of the sand and gravel separated by the separation equipment, and the sand and gravel adhered to the plasticizer are directly used as concrete aggregates for secondary When used for the first time, the plasticizer attached to the surface of the sand will affect the quality of the aggregate, and then affect the quality of the concrete after mixing
