Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete production, and particularly relates to a continuous gradation high-quality concrete green production line. BACKGROUND

[0002] In today's era, the continuous development of global economy and the steady growth of population jointly promote the rapid acceleration of urbanization process. The construction industry, as one of the core driving forces of urban development, is booming with an unprecedented scale and speed. Various engineering projects emerge in an endless stream, from the towering skyscrapers that shape the city skyline, to the crisscrossing bridges and tunnels that connect the vast land transportation network, to the extensive highways and railways that expand the spatial dimension of regional development, and to the industrial and civil buildings that meet people's diverse production and living needs. All of these have huge and growing demand for concrete as a basic building material. The quality of concrete is the lifeline of construction engineering, which not only directly determines the safety of building structure in bearing pressure and resisting natural disasters, but also deeply affects the durability of buildings in the long-term use process, such as impermeability, corrosion resistance and other key performance. Moreover, it is closely related to the functionality of the building, for example, the thermal insulation performance of concrete is directly related to the indoor environment comfort and energy consumption level. With the continuous innovation and progress of modern architectural design concept, and the increasing demand for building quality, the construction industry sets increasingly stringent standards for the performance indicators of concrete, not only requiring it to have basic characteristics such as high strength and high durability, but also posing new challenges in terms of work performance and environmental performance. Therefore, a continuous gradation high-quality concrete green production line is designed.

[0003] Traditional concrete production methods often have many problems. In terms of raw material processing, the gradation of aggregates such as sand and stone is difficult to control accurately, resulting in unstable and ideal performance of concrete. In the concrete mixing process, traditional mixing equipment usually uses a single mixing method, which is not uniform and is prone to material aggregation or segregation, seriously affecting the quality uniformity and strength stability of concrete. In addition, the connection between the traditional concrete production line and each link is not close and smooth enough. From the feeding of raw materials to the discharge of finished concrete, the whole process takes a long time, which cannot meet the rapid and efficient construction needs of modern large-scale construction projects.
