[0037] The utility model discloses a water injection subassembly 4 can be set up to the inside of stirring jar body 1 carries out high -efficient flushing. When needing to clean stirring jar body 1, just control total stirring shaft 5 drive C type wall scraping plate 7 rotation, and water injection subassembly 4 continues to inject water to the inside of stirring jar body 1, through the scouring of water flow and the rotation of C type wall scraping plate 7 scraping, can effectively remove the cement powder and fly ash particles remaining on the inner wall of stirring jar body 1, greatly improved the cleaning efficiency of stirring jar body 1, also reduced the workload of manual cleaning.
[0038] By setting the adjusting assembly 9, the angle of the stirring paddle 8 can be adjusted in real time according to the stirring requirements of different stages and the actual state of the material, greatly shortening the time for the material to be stirred and mixed evenly, and significantly improving the stirring efficiency. Specifically, in the initial stage of stirring, the stirring paddle 8 can be adjusted to a larger angle to increase the shear force between the stirring paddle 8 and the material, helping the stirring paddle 8 to better disperse the material and avoid the formation of clumps between the cement and fly ash particles. This can ensure the full loosening of the fly ash and cement, and improve the efficiency in the initial stage of stirring. As the stirring proceeds, the material gradually becomes uniform, and at this time the stirring paddle 8 is adjusted to a smaller angle, which helps to uniformly mix the components and reduces excessive shear between the materials, avoiding unnecessary energy consumption and excessive stirring. Through this real-time adjustment, not only the efficiency and quality of the stirring process are improved, but also the energy consumption is greatly reduced.
[0039] Specifically, during the stirring process, the water injection assembly 4 can flexibly inject water into the stirring tank body 1, thereby ensuring that the material can be better mixed.
[0040] Working principle: First, a certain amount of fly ash and cement is poured into the stirring tank body 1 from the inlet pipe one 31 and the inlet pipe two 32, and in the pouring process, the water injection assembly 4 is opened to start injecting an appropriate amount of water into the stirring tank body 1. At the same time, the total stirring shaft 5 is driven to rotate by the driving assembly 6, and the total stirring shaft 5 drives the C-shaped scraping plate 7 and the stirring paddle 8 to rotate together, thereby effectively mixing the fly ash, cement and water. In the early stage of stirring, the stirring paddle 8 is adjusted to a larger angle (45-75 degrees) by the adjusting assembly 9, and at this time the stirring paddle 8 mainly generates strong radial shear flow, which can effectively break up the dry powder agglomerates of fly ash and cement, thereby effectively dispersing the material. In the later stage of stirring, the stirring paddle 8 is adjusted to a smaller angle (15-45 degrees) by the adjusting assembly 9, and at this time the stirring paddle 8 mainly generates efficient axial circulation flow, which can promote the overall convection and uniform mixing of the slurry in the entire stirring tank body 1, thereby effectively mixing the material.

In addition, when cleaning the stirring tank body 1, the cooperation between the main spray head 43 and the C-shaped wall scraping plate 7 can effectively remove the adhesion on the inner wall of the stirring tank body 1, greatly improving the cleaning efficiency and reducing the need for manual intervention. At the same time, the auxiliary spray head 44 is vertically downward, which can spray water on the surface of the stirring paddle 8, playing a role in cleaning the stirring paddle 8, and effectively removing the residual material on the surface of the stirring paddle 8.
