Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of mixer, concretely relates to a special mixer for coal gangue mortar. BACKGROUND

[0002] With the continuous development of the construction industry, the performance and quality requirements of building materials are increasingly improved. As a kind of building material made of coal gangue as the main raw material, coal gangue mortar gradually gets widely used in construction engineering because of its good environmental performance and economic advantages.

[0003] The mixing quality of coal gangue mortar directly affects its use effect in construction. The traditional mixer has some obvious defects when mixing coal gangue mortar. The angle of the stirring blade of the general mixer is fixed and cannot be adjusted flexibly. Different construction processes and coal gangue mortar formulations have different requirements for the intensity, uniformity and mixing method of mixing. For example, in some scenarios that require rapid mixing to improve production efficiency, the existing mixer cannot provide sufficient mixing intensity and efficient mixing method due to the fixed angle of the stirring blade, resulting in prolonged mixing time and low production efficiency. In some projects with high requirements for mixing uniformity, the fixed angle of the stirring blade also makes it difficult to ensure that the components of coal gangue mortar are fully mixed, thereby affecting the quality and performance of the mortar and adversely affecting the quality of the construction project.

[0004] When the angle of the stirring blade can be flexibly changed, it will bring many benefits to the mixing of coal gangue mortar. In the initial stage of mixing, coal gangue and other materials have not been fully mixed, at which time the angle of the stirring blade can be adjusted to a larger value, such as close to 60°. The larger angle enables the stirring blade to act on the material with a larger tangential force during rotation, effectively breaking the agglomerates of coal gangue and allowing them to quickly disperse into other materials, accelerating the initial mixing of the overall material. As the mixing process progresses, the angle of the stirring blade can be appropriately reduced, for example, to about 50°, to form a more complex material flow pattern inside the material, guide the material to produce multi-directional convection in the mixer, avoid dead angles, and ensure that various material components, especially coal gangue and other additives with large differences in density and particle morphology, can fully contact and mix, greatly improving the mixing uniformity. Moreover, when mixing high-viscosity coal gangue mortar, adjusting the angle of the stirring blade in a timely manner can change the direction of the force exerted by the material on the blade, reduce the mixing resistance, make the mixing process smoother, reduce the energy consumption of the mixer, and prevent equipment wear and tear caused by excessive resistance, prolonging the service life of the equipment.

[0005] In summary, the existing mixer cannot meet different mixing requirements when mixing coal gangue slurry, and a new type of coal gangue slurry special mixer is urgently needed, which can flexibly adjust the angle of the stirring blade to adapt to various mixing conditions, thereby improving the mixing quality and efficiency of the coal gangue slurry.
