Description

A kind of concrete mixing equipment for water conservancy projects

Technical field

The utility model relates to the technical field of concrete preparation, in particular to a concrete mixing equipment for water conservancy projects.

Background technique

The mixer is responsible for uniform mixing in the concrete preparation process. Mixing is an important part of concrete quality control. During the mixing process, the blade angle directly affects the mixing effect of concrete. The blade angle refers to the acute angle between the mixing blade and the mixing shaft, which has an important impact on the circumferential and axial movement speed of the concrete. Therefore, only by controlling the angle between the mixing blade and the mixing shaft within an appropriate range can we ensure that both the axial and circumferential movements of the concrete can achieve greater speeds, so that the concrete can achieve good mixing effects and meet quality and efficiency requirements. At present, the mixing blades and the mixing shaft in existing concrete mixing equipment generally have an integrated structure, or the mixing blades are welded to the outer wall of the sleeve, and then the blades and the sleeve are integrally installed on the mixing shaft. The drive of the motor realizes high-speed rotation and mixes the concrete in the mixing barrel. This form of concrete mixing equipment has at least the following problems: First, once the mixing blades and mixing shaft are assembled, the blade angle cannot be adjusted. Therefore, when the composition or proportion of the concrete mixture changes, the blade angle cannot follow. Therefore, it is difficult to achieve the best mixing effect and has poor versatility. Secondly, the combination form between the mixing blade and the mixing shaft is relatively simple, resulting in unsatisfactory mixing effect and poor uniformity of the concrete mixture. Third, the mixing blades and the mixing shaft and/or the mixing blades and the outer wall of the sleeve are fixedly connected. Once a mixing blade is damaged, the entire mixing blade needs to be replaced, which greatly increases the equipment cost.

To sum up, the existing concrete mixing equipment has problems such as the blade angle cannot be adjusted, poor versatility, unsatisfactory mixing effect, poor uniformity of concrete mixture, and high equipment cost.
