Description

Technical Field

[0001] The present invention relates to the technical field of concrete production equipment, and particularly relates to a concrete segregation-resistant agent filling device. Background Art

[0002] As one of the most commonly used building materials in modern construction projects, the quality of concrete directly affects the safety, durability, and reliability of engineering structures. During the mixing production process of concrete, various admixtures are usually added to improve the workability of concrete and enhance the quality of the concrete mixture. Among them, the segregation-resistant agent is an important functional admixture. It can effectively prevent the segregation of concrete during the mixing, transportation, and pouring processes, ensure the uniform distribution of the components of concrete, and thus improve the overall performance of concrete.

[0003] However, in actual concrete production operations, the existing segregation-resistant agent filling devices have many deficiencies, seriously affecting the use effect of the segregation-resistant agent and the quality of the concrete mixture. The specific manifestations are as follows: Poor fixing effect of the fixed structure For the common segregation-resistant agent filling devices on the market currently, their connection methods with concrete mixing tanks are often relatively single and the fixing effect is not ideal. During the operation of the concrete mixing tank, due to the vibration and shaking generated by the rotation of the mixing shaft and the impact of materials, the connection between the filling device and the mixing tank is likely to become loose, thus affecting the stable filling of the segregation-resistant agent.

[0004] Lack of flexible adjustment ability Different concrete production projects have different requirements for the mix ratio and mixing volume of concrete. Therefore, the sizes of the concrete mixing tanks used are also different. However, most of the existing segregation-resistant agent filling devices adopt a fixed structure design, and parameters such as the filling position, angle, and filling range are preset and cannot be flexibly adjusted according to the actual size of the concrete mixing tank.

[0005] Uneven filling and poor dispersion effect Traditional segregation-resistant agent filling devices usually adopt a direct injection method, that is, the segregation-resistant agent is directly injected into the concrete mixing tank through a pipeline or a nozzle. Although this filling method is simple and direct, it has obvious defects. Since the concrete is in a continuous motion state in the mixing tank and the material flow speeds and directions in different parts are different, the directly injected segregation-resistant agent is difficult to quickly and evenly disperse into the concrete in the entire mixing tank in a short time. This is likely to cause the segregation-resistant agent concentration in some local areas of the mixing tank to be too high, while in other areas the concentration is too low or even absent, resulting in uneven quality and performance of the concrete mixture and affecting its performance in subsequent construction and use processes.

[0006] In summary, the existing anti-segregation agent filling device has poor fixing effect of the fixing structure, cannot be flexibly adjusted, uneven filling, and poor dispersion effect, which have seriously restricted the improvement of concrete production efficiency and quality. There is an urgent need to develop a new type of concrete anti-segregation agent filling device to solve these problems. Summary of the Invention
