Description

TECHNICAL FIELD

[0001] The application belongs to the field of building waste recycling, and particularly discloses a building waste recycling and stirring device. BACKGROUND

[0002] Building waste is various solid waste generated in the process of urbanization, engineering construction and demolition, including inert materials such as waste concrete blocks, brick masonry fragments and mortar residues, as well as a small amount of waste steel, wood and plastic impurities. The traditional disposal method of such waste is mainly open-air stacking or landfill, which not only occupies valuable land resources, but also easily causes heavy metal leakage to pollute soil and groundwater due to rainwater erosion, and dust evaporation aggravates air pollution. On the one hand, natural sand and gravel aggregates are facing resource depletion due to long-term exploitation, and recycled aggregates can replace part of the natural aggregates for engineering construction to alleviate the pressure of resource shortage. On the other hand, recycling can reduce carbon emissions and reduce the construction and maintenance cost of landfill sites. The recycling process is to separate waste steel, plastic and other impurities by manual or mechanical separation first, then use a crusher to crush large pieces of waste material to the required particle size, then use a conveyor to accurately transport the crushed material into the inside of a stirring drum, and then add water, curing agent and other materials for mixing, and finally prepare recycled building materials for backfilling in scenarios such as foundation pits and pipe corridors, relying on fluidity to fill complex spaces and improve construction efficiency and backfill density.

[0003] At present, the common building waste recycling and stirring device usually includes a crusher, a stirring drum and a driving system, and the working process is roughly as follows: the building waste is crushed by the crusher, then is centrally and cumulatively poured into the stirring drum through a fixed chute or a conveyor belt, and then the stirring blades are started to mix. However, the crushed materials, especially those with large differences in density and particle size, are centrally poured into the stirring drum to form a large pile at the bottom or one side of the stirring drum. The stirring blades need to consume a lot of energy and time to break up the pile in the initial stage. During this process, stirring blind spots are easily formed, which causes part of the light or powdery materials to not fully participate in the mixing, forming unevenly mixed materials, which seriously affects the quality of the finished product of the recycled building materials. In addition, due to the initial accumulation of materials, the stirring mechanism has a large starting load. In order to achieve the expected mixing uniformity, the stirring time has to be significantly prolonged, resulting in reduced production efficiency. SUMMARY
