Technical Field

The invention belongs to the technical field of concrete production, and particularly relates to a multifunctional concrete production system.

Background

Concrete is one of the most important civil engineering materials of the present generation. The artificial stone is prepared by a cementing material, granular aggregate (also called aggregate), water, an additive and an admixture which are added if necessary according to a certain proportion, and is formed by uniformly stirring, compacting, forming, curing and hardening. The concrete has the characteristics of rich raw materials, low price and simple production process, so that the consumption of the concrete is increased more and more. Meanwhile, the concrete also has the characteristics of high compressive strength, good durability, wide strength grade range and the like. These characteristics make it very widely used, not only in various civil engineering, that is shipbuilding, machinery industry, ocean development, geothermal engineering, etc., but also concrete is an important material.

The two most common types of concrete are cement concrete and asphalt concrete. During the production process of the asphalt concrete, the aggregate needs to be dried and heated to reach a certain temperature, and then the asphalt concrete is mixed with hot asphalt and cold mineral powder. In the existing asphalt concrete production system, during the process of producing asphalt concrete, the starting and stopping of production can form hot waste (aggregate with unstable temperature), and the hot waste is usually directly discharged and discarded, which not only causes environmental pollution, but also wastes raw materials.
