Description

Technical Field

[0001] The invention relates to the technical field of construction waste recycling, in particular to a construction waste classification, filtering and recycling device and a recycling method thereof. Background Art

[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and other wastes generated by people in the production activities of the construction industry such as demolition, construction, decoration, and repair. According to the source of generation, construction waste can be divided into engineering slag, decoration waste, demolition waste, engineering mud, etc.; according to the composition, construction waste can be divided into slag, concrete blocks, broken stones, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, etc.

[0003] Construction waste refers to construction waste generated in the project due to human or natural reasons, including waste soil, abandoned soil, silt and abandoned materials. These materials are of no help to the building itself, but they are substances generated in the process of construction and need to be treated accordingly in order to achieve the ideal project construction. Because it is an overall process, the consideration of its links is more important.

[0004] The recycling of construction waste requires granulation operations. Conventional recycling only uses simple crushing operations and then uses transport vehicles to transport it away. The dust cannot be handled during crushing, which can easily cause secondary pollution. The overall crushing size cannot be guaranteed, which increases the cost of subsequent recycling operations. In addition, there is a risk of leakage if the waste is not packaged during transportation. For this reason, we propose a construction waste classification, filtration and recycling device and a recycling method thereof to solve the above problems. Summary of the invention

A construction waste recycling method based on the construction waste classification, filtering and recycling device according to claim 5, characterized in that: The recovery method comprises the following steps: S1: The second dust discharge frame (37) is installed in the first chute (3351), the first installation frame (38) is installed in the second chute (3361), the dust outlet (371) is connected to the dust collection bag, the high-speed fan (381) is started, the concrete blocks are poured into the second feed trough (32), the vibration motor (334) is started to drive the vibration frame (33) to vibrate, the concrete blocks vibrate forward, and fine particles are filtered through the second filter (332) and enter the vibration frame (33). The high-speed fan (381) filters the fine dust through the third filter (3352) and blows it into the dust collection bag, and concrete particles of appropriate size enter the first feed trough (22) through the guide port (36); S2: large-sized concrete blocks enter the jaw crusher (35) through the guide rod (333), the concrete blocks crushed by the jaw crusher (35) enter the pulverizer (351), and the crushed concrete blocks are transported to the second feed trough (32) again through the right-angle conveyor (352), and then the step S1 is repeated; S3: Concrete particles of suitable size enter the discharge plate (23) through the first discharge port (221), and then the first filter screen (232) filters the fine dust that is not blown away by the high-speed fan (381), and discharges and collects through the second discharge port (241). Concrete particles of suitable size fall onto the conveyor belt (26), and the first motor (261) is started to drive the conveyor belt (26) to rotate and transport, and the concrete particles of suitable size are transported to the third feed trough (461); S4: The second motor (43) starts to drive the rotating plate (432) to rotate, thereby driving the first cylinder (44) to rotate to absorb the packaging bag. The first cylinder (44) rotates in the opposite direction to insert the upper opening of the packaging bag into the outside of the loading box (49). The second cylinder (481) drives the fourth mounting frame (48) to descend, and the side movable plate (484) unfolds to open the packaging bag, and concrete particles are fed in. After loading, the seal is manually removed.
