[0017] Method two: building solid waste aggregate shaping mode, in this mode, the aggregate shaping shaft rod assembly forms a coaxial accelerated reverse stirring shaping structure in the building solid waste aggregate shaping cylinder assembly. At this time, the building solid waste is added into the shaping cylinder through the closed feeding assembly. The centrifugal base screen serves as the supporting screen of the building solid waste at this time. The beating fan blade and the centrifugal base screen form a coaxial reverse rotation structure. Through the friction between the building solid waste aggregates, the friction of the aggregates on the shaping cylinder and the centrifugal base screen, and the beating and stirring of the building solid waste aggregates by the beating fan blade, the old mortar and surface dust on the building solid waste aggregates are removed, and the shaping of the building solid waste aggregates is realized.

At this time, the beating fan blade and the centrifugal base screen rotate in the same direction, and the rotating speed of the beating fan blade is greater than that of the centrifugal base screen. When the centrifugal base screen rotates, the building solid waste aggregates on the centrifugal base screen are thrown to the centrifugal discharge port by the centrifugal method to realize discharge. In this process, the acceleration of the beating fan blade relative to the centrifugal base screen realizes the accelerated rotation of the beating fan blade relative to the centrifugal base screen, so as to realize a stirring force for the discharge of the aggregates on the centrifugal base screen, and ensure that the aggregates on the centrifugal base screen can be smoothly discharged from the centrifugal discharge port.

[0020] Compared with the prior art, the building solid waste aggregate shaping device has the following beneficial effects: when the building solid waste aggregate is shaped, the beating fan blades on the aggregate shaping shaft rod assembly and the centrifugal base sieve form a coaxial reverse rotation structure, at this time, the building solid waste aggregate rotates on the centrifugal base sieve, and through the relative reverse rotation of the beating fan blades, the building solid waste aggregate is shaped by the friction between the building solid waste aggregates, the rolling friction between the aggregate and the cylinder, and the reverse high-efficiency rotation of the beating fan blades, so that the old mortar and surface dust on the building solid waste aggregate are removed, thereby realizing the shaping treatment; meanwhile, through the directional rotation of the closed feeding assembly, the feeding end and the discharging end of the closed feeding assembly are simultaneously fed and discharged, and the closed treatment of the feeding end of the building solid waste aggregate shaping cylinder assembly is realized without interference between the feeding and discharging, thereby avoiding dust raising; in the above process, through the cooperation of the exhaust fan, the spiral conveying plate and the semicircular filter screen at the bottom of the building solid waste aggregate shaping cylinder assembly, the removed old mortar and surface dust can be removed from the building solid waste aggregate in time, and the removed old mortar and surface dust can be collected and treated, and the semicircular filter screen is prevented from being blocked to cause poor negative pressure collection; after the building solid waste aggregate is shaped, the beating fan blades on the aggregate shaping shaft rod assembly and the centrifugal base sieve form a coaxial and same-direction rotation structure, the rotation speed of the beating fan blades is greater than that of the centrifugal base sieve, at this time, the building solid waste aggregate rotates on the centrifugal base sieve, and the centrifugal base sieve centrifugally throws the building solid waste aggregate to the centrifugal discharge port; in this process, because the rotation speed of the beating fan blades is greater than that of the centrifugal base sieve, the beating fan blades have a pushing force on the building solid waste aggregate, which is equivalent to accelerating the centrifugal discharge of the building solid waste aggregate.

5. The method for using the physical shaping device for recycled aggregate from construction solid waste according to claim 4, characterized in that: Step 1: In a directional rotation-type closed feeding mode for construction solid waste aggregates, the partitioned storage fins (310) divide the closed lower hopper (301) into a plurality of non-connected partitioned storage chambers (311). At this time, the feeding end and the discharging end of the closed lower hopper (301) are directly opposite to and separated from the different partitioned storage chambers (311). Through the cooperation of the directional limiting wheel (305) and the directional toggle wheel (308), the directional and precise transposition rotation of the plurality of partitioned storage chambers (311) is achieved, thereby achieving the synchronous feeding and unloading of the plurality of partitioned storage chambers (311) directly opposite to the feeding end and the discharging end of the closed lower hopper (301); Step 2: Construction solid waste aggregate shaping mode. In this mode, the aggregate shaping shaft assembly (200) forms a coaxial accelerated reverse material shaping structure in the construction solid waste aggregate shaping cylinder assembly (100). At this time, the construction solid waste is added to the shaping cylinder (101) through the closed feeding assembly (300). At this time, the centrifugal bottom screen (202) serves as a supporting screen for the construction solid waste. The striking fan blades (203) and the centrifugal bottom screen (202) form a coaxial reverse rotation structure. Through the friction between the construction solid waste aggregates, the friction of the construction solid waste aggregates on the shaping cylinder (101) and the centrifugal bottom screen (202), and the striking and stirring of the construction solid waste aggregates by the striking fan blades (203), the old mortar and surface dust on the construction solid waste aggregates fall off, thereby achieving the shaping of the construction solid waste aggregates. Step 3: Negative pressure collection mode for old mortar and surface dust on construction solid waste aggregates. During the action of step 1, the exhaust fan (114) forms a downward negative pressure dust extraction structure in the shaping cylinder (101). Through this structural design, the old mortar and surface dust on the construction solid waste aggregates, when falling off, immediately flow downward under negative pressure through the centrifugal bottom screen (202). During this process, they are filtered and collected by the semicircular filter (119). The old mortar and surface dust filtered out of the semicircular filter (119) are centrally transported to the dust collection discharge pipe (116) by the spiral conveying plate (118); Step 4: Construction solid waste aggregate toggle type centrifugal discharge mode. In this mode, the aggregate shaping shaft assembly (200) forms a coaxial acceleration and unidirectional centrifugal discharge structure in the construction solid waste aggregate shaping cylinder assembly (100). At this time, the second reversing cone gear (214) is meshed with the second driving cone gear (208). The synchronous gear arm (213) realizes the release of the sealing door (111) from the centrifugal discharge port (112) by pressing the push switch (108). At this time, the striking fan blade (203) and the centrifugal chassis screen (202) rotate in the same direction, and the speed of the striking fan blade (203) is greater than that of the centrifugal chassis screen (202). 02), when the centrifugal chassis screen (202) rotates, the construction solid waste aggregates on the centrifugal chassis screen (202) are thrown to the centrifugal discharge port (112) by centrifugal means to achieve discharge. In this process, the acceleration of the striking fan blade (203) relative to the centrifugal chassis screen (202) is achieved, so that the striking fan blade (203) is accelerated relative to the centrifugal chassis screen (202), thereby achieving a discharging force for the construction solid waste aggregates on the centrifugal chassis screen (202), ensuring that the construction solid waste aggregates on the centrifugal chassis screen (202) can be smoothly centrifugally discharged from the centrifugal discharge port (112).
