Description

Technical Field

[0001] The utility model relates to the technical field of recycled aggregates, in particular to a mixing station stirring device. Background Technique

[0002] Recycled aggregates refer to miscellaneous fill that has undergone several rounds of screening and processing by machines to become small-grained recycled aggregates. According to the aggregate particle size, they are divided into recycled fine aggregates and recycled coarse aggregates. Particles with a nominal particle size greater than 5 mm are recycled coarse aggregates, and particles with a nominal particle size less than 5 mm are recycled fine aggregates. Compared with natural sand and gravel aggregates, recycled aggregates are themselves bricks and tiles or still have a considerable amount of cement mortar wrapped on the surface. The surface is rough and has many edges and corners. Coupled with the fact that a large number of microcracks exist inside the recycled aggregates due to damage accumulation during the disassembly and crushing of concrete blocks, the apparent density of recycled aggregates is lower than that of ordinary aggregates, the water absorption rate is high, the water absorption speed is fast, and the crushing index of recycled aggregates is higher than that of natural aggregates. The physical properties such as the apparent density, water absorption rate, and crushing index of recycled aggregates are related to factors such as the strength grade, mix ratio, service time, service environment, and region of the parent concrete. Due to the large quality differences in waste concrete or bricks and tiles, the performance differences of recycled aggregates prepared by simple processes are also relatively large, which is not conducive to the popularization and application of recycled aggregates. In order to ensure and improve the performance of recycled concrete, the raw materials of recycled aggregates obtained by simple coarse crushing are classified.

[0003] Existing recycled aggregates are weighed by a weighing bin for the recycling agent and RAP material and then enter the mixing cylinder for mixing. However, the mixing time of the recycling agent and RAP material in the weighing bin is limited. Therefore, the fusion effect of the recycling agent and RAP is limited, affecting the quality of recycled aggregates. Therefore, a mixing station stirring device is proposed to solve the problems mentioned above. Content of the Utility Model

[0008] Furthermore, a partition is installed inside the installation shell.

The bottom end of the regenerated weighing bin is fixedly communicated with the upper surface of the stirring cylinder, and valves are installed on both the first through pipe and the bottom end of the regenerated weighing bin.

[0011] Furthermore, a cavity and a guide groove are formed inside the telescopic shell. One end of the return spring away from the scraping plate is fixed to the inner wall of the cavity, and a vibration motor is installed on the outer wall of the regenerated weighing bin.
