[0015] A construction waste recycling method, using the above-mentioned construction waste processing equipment, comprises the following steps:

[0016] The movable mounting plate moves so that the feed port is located directly above the screening rotating plate, and solid construction waste such as bricks and cement blocks are poured into the crushing processing barrel. The construction waste falls into a cylindrical cage-shaped container formed by a number of screening baffles. The movable mounting plate moves so that the lifting and crushing plate is located directly above the screening rotating plate. The crushing baffle moves downward so that a crushing baffle exists in the gap between every two adjacent screening baffles, so that the several screening baffles and the several crushing baffles form a cylindrical container. The lifting and crushing plate moves back and forth vertically to impact and squeeze the construction waste in the cylindrical container. When the lifting and crushing plate moves back and forth vertically, the rotating spray ring plate rotates back and forth at a certain amplitude, and the dust removal nozzle sprays water mist when the rotating spray ring plate rotates;

[0017] After the crushing work is completed, the lifting crushing plate and the crushing baffle move upward to the highest position, several screening baffles move to adjust the gap size between adjacent screening baffles, and the screening rotating plate rotates, driving the construction waste fragments in the cage-shaped container to rotate.

[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 the crushing baffle move upward to the highest position, and several screening baffles move to adjust the gap size between adjacent screening baffles. The screening rotating plate rotates, driving the construction waste fragments in the cage-shaped container to rotate, and the smaller garbage fragments are thrown out from the gap between the screening baffles and fall into the collection box, and the larger connected fragments cannot be thrown out of the cage-shaped container; the size of the gap between the screening baffles is adjusted, so that the screening adjustment can be made according to the required fragment size, and construction waste fragments of different screening sizes can be screened, thereby improving the applicability of the device. The crushed construction waste is screened so that the larger construction waste fragments remain in the cage-shaped container, and then secondary crushing is carried out until the construction waste fragment size meets the requirements. Construction waste can still be added before the secondary crushing, thereby improving work efficiency.

[0020] 2. The lifting and crushing plates move back and forth vertically to impact and squeeze the construction waste in the cylindrical container. When the lifting and crushing plates move back and forth vertically, 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 when 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 to prevent construction waste from moving into the gap between the screening baffles during crushing, affecting the crushing effect and subsequent screening.
