Cement paste stirring device and method

Abstract

The invention discloses a cement paste stirring device and method. The cement paste stirring device comprises a power module, a stirring device body, a paste discharging device and a stirrer container. The stirring device body is arranged inside the stirrer container. The power module provides power for the stirring device body. Stirred cement flows out of the paste discharging device. The stirring device body comprises a rotating shaft, and a plurality of fan blades are arranged at the bottom of the rotating shaft. The other end of each fan blade is connected with one end of a corresponding reinforcing steel bar. Each reinforcing steel bar has a certain bent radian, and the other ends of the bent reinforcing steel bars are connected to the upper portion of the rotating shaft. The stirring device body can effectively stir cement paste in the stirrer container, the phenomenon that the cement paste at the bottom of the container cannot be sufficiently stirred due to the excessively-high fan blades is avoided, and the bent reinforcing steel bars also play a stirring effect and can stir the cement paste around the stirrer container. In this way, the stirring device body can stir the cement paste inside the container in an all-dimensional mode without dead angles, and stirring quality of the cement paste is guaranteed.

Description

Technical field [0001] The invention relates to the field of civil engineering, in particular to a cement slurry mixing device and method. Background technique [0002] Cement slurry is an important part of concrete materials. Its mixing uniformity will affect the strength of concrete. The current concrete mixing method is to mix all the concrete components together. This mixing method will cause the mixing of cement and water. Uneven, cement tends to form agglomerates. Therefore, consider mixing the cement and water before adding it to the concrete aggregate. This will greatly improve the utilization efficiency of the cement and increase the mechanical strength of the concrete under the same amount of cement. During the relevant experiments, it was found that there is no cement slurry mixing device suitable for indoor experiments. The existing mixers on the market have too large capacity. Each experiment needs to put at least 150kg of cement, which will cause a large amount of c...

AI Technical Summary

Problems solved by technology

When carrying out relevant experiments, it was found that there is no cement slurry mixing device suitable for indoor experiments. The existing mixers in the market have too much capacity, and at least 150kg of cement needs to be put into each experiment, which will cause a lot of waste during the experiment. Waste, and because the mixing fan blade is too small due to the unreasonable design of the mixer, some cement will settle during the mixing process and consolidate at the bottom of the machine, which not only seriously affects the accuracy of the water-cement ratio of the cement slurry, but also due to cement settlement during later cleaning Consolidation greatly increases the difficulty of cleaning

The existing cement slurry mixing device cannot conveniently take the cement slurry during the mixing process, which causes inconvenience to the indoor test
