Description

Technical Field

[0001] The invention relates to the technical field of building waste sorting, and in particular to a recycled aggregate cone-disk stacking machine. Background Art

[0002] Aggregate is a granular loose material that acts as a skeleton or filler in concrete. Aggregate, as the main raw material in concrete, plays a skeleton and supporting role in buildings. Recycled aggregate is a kind of building material obtained by crushing, screening and sorting construction waste. The composition of construction waste is relatively complex, so the recycled aggregate obtained by processing is not pure enough and there will be light substances mixed in it. Due to the large content of light substances, it is bound to affect the strength of concrete. When cement is mixed with water, it is easy to clump with water molecules, hindering the hydration of cement. Moreover, due to its large volume change, it will cause the concrete layer to swell and crack.

[0003] However, the existing construction aggregate sorting device is not effective during use, cannot fully sort the aggregate, and the processing efficiency is not high. At the same time, the sorting process is carried out in the open air, resulting in dust adhering to the aggregate during sorting being diffused in the air.

[0077] The working principle of the present invention is as follows:

[0078] During the processing of the recycled aggregate, the recycled aggregate is transported to the feed port 1 of the recycled aggregate cone disc stacking machine through a belt conveyor. After the recycled aggregate slides in from the feed port 1, it will be concentrated on the stacking plate 4. After the stacking plate 4 is full, it will slide from the circumference of the stacking plate 4 to the first small cone disc 5. The recycled aggregate will slide down along the outer conical surface of the first small cone disc 5. Under the guidance of the guide partition between the guide plates 31, the recycled aggregate can fall evenly along the circumference of the first small cone disc 5. When the recycled aggregate slides off the first small cone disc 5, the recycled aggregate will be discharged from the first small cone disc 5. When the first cone disk 5 is formed, the baffle 32 is perpendicular to the generatrix of the first small cone disk 5 and is arranged at an angle less than 45° with the generatrix, so that the recycled aggregate moves upward when leaving the outer wall of the small cone disk. The aggregate and light materials have a larger space in the air, that is, the density becomes smaller. At this time, it is beneficial for the wind force of the first air outlet 29 to perform the first sorting of the recycled aggregate. The light materials in the recycled aggregate are blown to the outside of the first large cone disk 6 under the action of the wind, and the recycled aggregate falls into the first large cone disk 6. The large cone 6 is a process of re-concentrating the aggregate from dispersion. After the aggregate is concentrated, it slides to the second small cone 7. The aggregate slides down along the outer conical surface of the second small cone 7. After the aggregate slides off the second small cone 7, the wind force of the second air outlet 30 performs a second sorting on the aggregate. The principle is the same as that of the sorting in the first small cone 5. The guide plate 31 and the baffle 32 on the second small cone 7 also make the light materials in the second sorting more accurately sorted out. The light materials in the aggregate are sorted out by the wind. The aggregate is blown to the outside of the second large cone disk 8 under the action of the wind, and falls into the second large cone disk 8. The aggregate slides into the second discharge port 3 along the second large cone disk 8, and the selected light materials fall along the inner circle of the upper main body 12, the middle main body 13, and the lower main body 14 and fall into the first discharge port 2. The aggregate will produce dust in the process of sliding and being blown by the wind. The dust will be sucked away by the third air duct 11. The air outlet of the third air duct 11 is connected to the air duct of the external dust collector, and the dust collector absorbs the dust.
