[0002] Construction waste refers to the waste generated by people engaged in demolition, construction, decoration and other construction industries. It is generally waste such as old concrete and old bricks and stones. These are relatively hard wastes. Construction waste can often be reused multiple times. For example, bricks and stones can be crushed into smaller pieces for road paving, etc. Targeted waste treatment equipment for construction projects is usually selected.

[0003] The crushed construction waste produces fragments of varying sizes, which usually require further screening after being removed from the processing equipment. Because the required fragment size varies each time the waste is crushed, screening equipment of different sizes is needed, making the screening process cumbersome and inefficient.

[0015] A method for recycling construction waste, using the aforementioned construction waste processing equipment, includes the following steps;

[0016] The movable mounting plate moves so that the feed inlet is directly above the screening rotating plate, and solid construction waste (either bricks or cement blocks) is poured into the crushing and processing bucket. The construction waste falls into a cylindrical cage-like container formed by several screening baffles. The movable mounting plate moves so that the lifting crushing plate is directly above the screening rotating plate, and the crushing baffle moves downward so that there is a crushing baffle in the gap between every two adjacent screening baffles, so that several screening baffles and several crushing baffles form a cylindrical container. The lifting crushing plate moves vertically back and forth, impacting and squeezing the construction waste in the cylindrical container. When the lifting crushing plate moves vertically back and forth, the rotating spray ring plate rotates back and forth at a certain amplitude. When the rotating spray ring plate rotates, the dust removal nozzle sprays water mist.

[0017] After the crushing operation is completed, the lifting crushing plate and crushing baffle move upward to the highest position, and several screening baffles move to adjust the gap between adjacent screening baffles. The screening rotating plate rotates, which drives the construction waste fragments in the cage container to rotate. Smaller waste fragments are thrown out from the gap between the screening baffles and fall into the collection box, while larger waste fragments cannot be thrown out of the cage container.

[0018] Compared with the prior art, the present invention provides a construction waste treatment device and a construction waste recycling method, which have the following beneficial effects:

[0019] 1. The lifting crushing plate and crushing baffle move upwards to their highest position, and several screening baffles move. Adjusting the gap between adjacent screening baffles causes the screening rotating plate to rotate, driving the construction waste fragments in the cage-like container to rotate. Smaller fragments are thrown out through the gaps between the screening baffles and fall into the collection box, while larger fragments cannot be thrown out of the cage-like container. Adjusting the gap between the screening baffles allows for screening of fragments of different sizes, improving the applicability of the device. After crushing, the construction waste is screened, leaving larger fragments in the cage-like container for secondary crushing until the fragments meet the required size. Construction waste can still be added before the secondary crushing, improving work efficiency.

[0020] 2. The lifting crushing plate moves vertically back and forth, impacting and squeezing the construction waste inside the cylindrical container. When the lifting crushing plate moves vertically back and forth, the rotating spray ring plate rotates back and forth at a certain amplitude. When the rotating spray ring plate rotates, the dust removal nozzle sprays water mist, which can spray while crushing the construction waste to prevent dust from flying and polluting the environment.

[0021] 3. The crushing baffle moves downward so that there is a crushing baffle in the gap between every two adjacent screening baffles, so that several screening baffles and several crushing baffles form a cylindrical container, preventing construction waste from moving into the gap between the screening baffles during crushing, which would affect the crushing effect and subsequent screening.

A feed inlet 101 is fixedly installed on the top surface of the movable mounting plate 201. A screening rotating plate 301 is installed inside the crushing and processing barrel 1. A collection box 302 is fixedly installed on the bottom surface of the crushing and processing barrel 1. A screening baffle 401 is installed on the top surface of the screening rotating plate 301. A crushing baffle 203 is installed in the gap between every two adjacent screening baffles 401. A lifting crushing plate 202 is installed above the screening rotating plate 301. A rotating spray ring plate 204 is installed above the screening baffle 401. Several dust removal nozzles 205 are fixedly installed on the top surface of the rotating spray ring plate 204.

[0040] When the movable mounting plate 201 moves, it enables the lifting crushing plate 202 and the crushing baffle 203 to move. The screening baffle 401 can move away from the central axis of the screening rotating plate 301 to adjust the gap between adjacent screening baffles 401. The crushing baffle 203 and the lifting crushing plate 202 can move vertically, and the screening rotating plate 301 can rotate. When the lifting crushing plate 202 moves upward, it can drive the rotating spray ring plate 204 to rotate, and the dust removal nozzle 205 can spray water mist.

The lifting crushing plate 202 moves vertically back and forth to impact and squeeze the construction waste in the cylindrical container. When the lifting crushing plate 202 moves vertically back and forth, the rotating spray ring plate 204 rotates back and forth at a certain amplitude. When the rotating spray ring plate 204 rotates, the dust removal nozzle 205 sprays water mist, which can spray while crushing the construction waste to prevent dust from flying and polluting the environment.

[0042] After the crushing operation is completed, the lifting crushing plate 202 and the crushing baffle 203 move upward to the highest position, and several screening baffles 401 move to adjust the gap between adjacent screening baffles 401. The screening rotating plate 301 rotates, causing the construction waste fragments in the cage container to rotate. Smaller fragments are thrown out through the gaps between the screening baffles 401 and fall into the collection box 302, while larger fragments cannot be thrown out of the cage container. By adjusting the gap between the screening baffles 401, the screening can be adjusted according to the required fragment size, allowing for the screening of construction waste fragments of different sizes, thus improving the applicability of the device. The crushed construction waste is screened so that larger fragments remain in the cage container for secondary crushing until the fragment size meets the requirements. Construction waste can still be added before the secondary crushing, improving work efficiency.
