Problems solved by technology
[0003] During the cold recycling process, problems such as uneven coating of asphalt and uneven mixing between components are likely to occur, and whitening phenomenon occurs
However, due to the larger particles of inorganic aggregates in each component in cold recycling and the higher viscosity of asphalt, it is necessary to mix the components evenly and coat the asphalt on the aggregate evenly, which requires a lot of mixing equipment. higher

The invention discloses a cold-recycling mixing apparatus, comprising: a mixing cylinder including a plurality of cylinder blocks transversely arranged and equal in cross-sectional area, with every two adjacent cylinder blocks communicated through an extrusion passage and the cross-sectional area of the extrusion passage less than that of the cylinder blocks; and a stirring shaft extending from the first of the multiple cylinder blocks to the last, with the stirring shaft provided with a plurality of stirring blade groups and at least one stirring blade group arranged in each cylinder block; wherein one stirring blade group in any cylinder block includes at least two stirring blades, and each stirring blade includes a first portion, a second portion and a third portion connected in sequence, and wherein the first portion is connected to the stirring shaft, the first portion and the third portion are of sheet structure made with metal, and the second portion is a metal chain connecting the first portion and the third portion. The cold-recycling mixing apparatus provides improved mixing uniformity of components during cold recycling.
Description
technical field [0001] The invention relates to a cold regeneration mixing equipment. Background technique [0002] At present, my country's highway construction is developing rapidly, and the annual investment scale has exceeded 200 billion yuan. The highways built in the past years have entered the period of major and medium repairs, and a large number of digging and milling asphalt mixtures have been discarded, causing environmental pollution. pollute. And road construction needs high-quality asphalt materials and stone materials. Extensive use of new stone materials and ore mining will lead to damage to the ecological environment. Asphalt cold recycling technology will require repaired and abandoned asphalt pavement, after digging, recycling, crushing, using new aggregates and new asphalt materials in an appropriate proportion, re-mixing, and leveling and compacting to form a pavement that meets road performance. recycled asphalt mixture. The recycling of asphalt mixtu...
