Description
Technical Field
[0001] The present application relates to the technical field of concrete processing and production, and in particular to a device for preparing concrete using alkali-activated mineral powder cementitious materials. Background Art
[0002] With the development of society, the technology of preparing concrete from coal gangue and mine water has made initial progress, and the use of alkali-activated mineral powder cementitious materials to prepare concrete has gradually matured. Alkali-activated mineral powder cementitious materials are mainly industrial by-products fly ash, mineral powder, etc., which can make reasonable resource utilization of solid waste, and have the advantages of low production energy consumption, high strength, rapid strength development, better wear resistance and erosion resistance. In the existing technology, the raw materials are generally placed inside the mixing tank, and then the motor is started to drive the stirring rod to stir it, thereby preparing concrete.
[0003] In actual use, due to the high viscosity of the activator, it is difficult to stir. The existing motor generally drives a single stirring rod for stirring, which makes the stirring relatively uneven, and then leads to unstable concrete performance, resulting in low quality of the prepared concrete. Therefore, an improvement is now made to a device for preparing concrete using alkali-activated mineral powder cementitious materials. Utility Model Content

[0014] By adopting the above technical solution, the bearing seat is provided so that the rotating shaft is movably connected to the mixing barrel, which facilitates the driving motor to drive the rotating shaft to rotate.
[0015] As a preferred technical solution of the present application, a plurality of stirring blades are fixedly connected to the outer surface of the stirring rod, and there is a gap between the stirring blades and the stirring barrel.
[0016] By adopting the above technical solution, it is ensured that the stirring blade can rotate freely during the stirring process, while avoiding friction or jamming with the barrel wall of the stirring barrel, which would affect the stirring effect and the normal operation of the equipment.
