Description

Technical Field

[0001] The utility model belongs to the technical field of storage equipment, and in particular relates to a concrete admixture anti-sedimentation device. Background Art

[0002] Concrete admixtures are added during the mixing of concrete, accounting for less than 5% of the mass of cement. Concrete admixtures include water reducers, retarders, air entraining agents, pumping agents, early strength agents and other admixtures. The application of concrete admixtures in engineering projects has received more and more attention. The addition of admixtures plays a certain role in improving the performance of concrete.

[0003] Usually when admixtures are used in concrete, the probability of admixture precipitation often increases due to insufficient mixing, and the existing mixing devices on the market do not have a strong mixing force for materials such as concrete. This results in the admixture and concrete being mixed but adhered to each other due to the weak force. The admixture attached to the inside of the mixing drum cannot be mixed, which easily leads to a certain degree of waste, and thus has a negative impact on the performance of the concrete. In addition, the material at the bottom of the mixing drum cannot be turned over during the mixing process, which causes the admixture at the bottom to be easily ignored during the mixing process, thus causing precipitation.

[0004] In view of this, the present utility model is proposed. Utility Model Content
