Description

Technical Field

The utility model relates to the field of nano reinforced modified concrete, in particular to a preparation device of nano reinforced modified concrete.

Background

The concrete is an artificial stone widely used in building engineering, and is prepared by stirring, compacting and curing cementing materials, coarse and fine aggregates, water, additives and the like according to a certain proportion. The quality and performance of the concrete not only depend on the quality and proportion of raw materials, but also are affected by the stirring process; the stirring process is an important link for preparing concrete, and aims to fully mix various raw materials to form uniform and consistent mixture so as to meet engineering requirements; in the stirring process, the factors such as the type, structure, parameters, operation mode and the like of the stirring device, the characteristics, the consumption, the adding sequence and the like of raw materials are required to be considered, so that the aims of high stirring efficiency, good uniformity, low energy consumption and the like are achieved.

At present, raw materials for concrete production have uneven quality and large quality fluctuation, produced concrete is extremely easy to cause concrete slump loss due to transportation distance and pumping distance, concrete workability is unstable, and stirring devices commonly used in concrete production comprise a forced stirrer and a free stirrer. The forced mixer is to perform forced shearing, turning and pushing movements on raw materials by rotating stirring blades or stirring arms, so that the raw materials can be uniformly mixed in a short time. The free stirrer is characterized in that the raw materials are subjected to free falling motion through a rotary barrel body or a barrel body, so that the raw materials collide, rub, roll and the like under the action of gravity, and the uniform mixing effect is achieved in a long time. The forced mixer is suitable for concrete with high strength, high performance, high durability and other requirements, and the free mixer is suitable for concrete with low requirements on common strength, common performance, common durability and the like.

However, both the forced mixer and the free mixer have some problems and disadvantages in practical production. For example, forced mixers may result in portions of the raw materials not being adequately mixed due to the clearance between the blades or arms and the tub wall; the free stirrer is limited by gravity, so that part of raw materials cannot be fully turned over, and partial thick and thin uneven or eccentric phenomenon is caused. In addition, different types of stirring devices can damage or consume raw materials to different degrees, and the working performance and mechanical properties of the concrete are affected.
