A multi-stage screening barrel connected below is nested on the outer side of the inner barrel microwave radiation separation barrel 20, and the outer barrel is a large particle storage barrel 21, a medium and small particle storage barrel 22, and an impurity barrel screening barrel 23. The separated aggregate can be completely discharged from the discharge port 18 by grade under the impact of the auxiliary discharge system 6 after screening, and the separation and grading work is performed. Each outer barrel is provided with a discharge port 18. The box body is supported by a box body bracket 100.

[0034] This equipment is used for aggregate separation and grading treatment of abandoned buildings, especially asphalt and other viscous and difficult-to-separate aggregate pavements. The device is provided with a feed port 4, a microwave generation control system 7, motors 5, 24, an auxiliary cleaning system 6, a discharge port 18, a temperature and pressure measurement module 29, and a dust and toxic gas exhaust suction port 16 in the box body to achieve complete graded separation of aggregates without adhesion, and ensure the immediate discharge of dust and toxic gases during the use of the equipment.

[0035] like Figure 1 , Figure 2 As shown, the equipment box is set as four nested cylinders with horizontal axes, and the inside is microwave radiation separation cylinder 20, large particle storage cylinder 21, medium and small particle storage cylinder 22 and impurity cylinder 23 from the inside to the outside; the latter three storage cylinders are concentric cylinders, and microwave radiation separation cylinder 20 and storage cylinder are non-concentric cylinders. Except for impurity cylinder 23, microwave radiation separation cylinder and the cylinder walls of each level of storage cylinder are provided with sieve holes, and the outer side of the cylinder is provided with a rotatable steel brush. Microwave radiation separation cylinder 20 and multi-stage screening cylinder are connected with different motors, and can be rotated in steps.

[0036] It also includes a barrel wall cleaning mechanism, which includes a rotatable steel brush system arranged on a box body and in contact with the multi-stage screening barrel wall. The steel brush system includes a horizontal axis connected to a gear set, and a plurality of steel brushes 15 are distributed on the horizontal axis. The gear set 26 is connected to the first-stage motor 5 through a meshing gear connection belt.

[0037] The first-stage motor 5 is coaxially fixed with the meshing gear 2 and the coaxial gear 28. The first-stage motor 5 of the equipment is coaxially fixed with the gear. The coaxial meshing gear 2 of the first-stage motor is meshed and connected with the peripheral meshing gear 8 fixed to the outer wall of the microwave radiation separation barrel 20. The coaxial gear 28 of the first-stage motor 5 is connected with the transmission gear 1 through the belt 3, which drives the gear set 26 to rotate, and then drives the steel brush 15 system to rotate.

[0038] The first-stage motor 5 drives the microwave radiation separation barrel 20 and the gear set 26 to rotate, and then drives the steel brush 15 system to rotate, ensuring that the sieve holes are cleaned while the aggregate is separated, thereby ensuring the separation efficiency of the microwave radiation separation barrel 20.

[0039] The two ends of the microwave radiation separation barrel 20 are supported inside the box body by being fixed to the first and second annular tracks 30 and 32 of the box body 14 and the bottom 19 of the outer cylinder, and the first and second ball belts 31 and 33 are respectively arranged between the tracks and the inner wall of the microwave radiation separation barrel. A plurality of separation scimitar blades 11 are fixed at equal intervals on the inner wall of the microwave radiation separation barrel, and the direction of the blades is opposite to the direction of the barrel, and the separation effect is increased in the reverse direction.

[0040] The microwave generation control system 7 includes a plurality of microwave triggers 9 and microwave guide ports 27 of different heights. The microwave triggers 9 are fixed on microwave trigger fixing shafts 10 of different heights. Different amounts of construction waste release microwaves through microwave triggers 9 of different heights to trigger microwave guide ports 27 of different heights. The microwave trigger fixing shaft 10 is fixed to the outside of the inner barrel. Different amounts of construction waste release microwaves through microwave triggers 9 of different heights to trigger microwave guide ports 27 of different heights, which control the maximum and minimum amounts of construction waste when microwaves start to radiate in the microwave radiation separation barrel 20.

[0041] The large particle storage barrel 21, the small and medium particle storage barrel 22 and the impurity barrel 23 are concentric barrels, and the large particle storage barrel 21, the small and medium particle storage barrel 22 and the impurity barrel 23 are fixed on the bottom surface of the same outer barrel, and the second-stage motor 24 drives the bottom surface of the outer barrel to rotate, and at the same time drives the large particle storage barrel 21, the small and medium particle storage barrel 22 and the impurity barrel 23 to rotate together. Several groups of guide fins 12 are fixed on the inner walls of the large particle storage barrel 21, the small and medium particle storage barrel 22 and the impurity barrel 23, respectively. The fin density and length of the guide fins 12 are related to the size of the particles guided in the connecting barrel, and the guiding direction is opposite to the direction of the barrel, which can relatively prolong the screening time of the aggregate in the screening barrel to ensure the screening effect.

[0042] Both sides of the microwave radiation separation barrel 20 are connected to the active track, the large particle storage barrel 21, the small and medium particle storage barrel 22, and the impurity barrel 23 are fixedly connected to the outer barrel wall, and the outer barrel bottom 19 is movably connected to the box body 14. The movable connection is provided with a ball that can slide and rotate along the track and a fixed track.

[0043] The large particle storage barrel 21, the medium and small particle storage barrel 22 and the impurity barrel 23 are connected to the bracket by ball bearings, which facilitates the rotation of the classification barrel.

[0044] Brushes are provided at the connection between the fixed track and the ball to prevent impurities or dust from entering the gap between the track and the ball and affecting the rotation of the components.

[0045] The auxiliary cleaning system 6 is respectively provided with a cleaning nozzle 13 corresponding to the large particle storage barrel 21, the medium and small particle storage barrel 22, and the impurity barrel 23. It can be considered that high-pressure jet or water spray is set according to actual needs. When the aggregate is not convenient to remove, all aggregates are cleared out under the promotion of the auxiliary cleaning system. The three cleaning nozzles can be operated separately.

[0046] The large particle storage barrel 21, the small and medium particle storage barrel 22, and the impurity barrel 23 are circular barrels with successively decreasing axial lengths. The reduced portion between the lower-level barrel and the upper-level barrel is provided with a barrel discharge port 18; the corresponding portions of the discharge ports 18 of the large particle storage barrel 21, the small and medium particle storage barrel 22, and the impurity barrel 23 are all provided with a barrel body bracket 25 with ball supports. The discharge ports 18 of the large particle storage barrel 21, the small and medium particle storage barrel 22, and the impurity barrel 23 are set at fixed positions of each barrel. When the second-level motor 24 stops rotating and the large particle storage barrel 21, the small and medium particle storage barrel 22, and the impurity barrel 23 are stationary, the discharge port 18 returns to the lowest point, exposed to the outside of the box body 14, and can be opened by axial rotation along the axis AB. Figure 3 shown.

[0047] The auxiliary cleaning system 6 is connected to the box 14 on the opposite side of the discharge port 18 of the multi-stage screening barrel. The auxiliary cleaning system 6 is provided with a cleaning nozzle 13 corresponding to each multi-stage screening barrel, which can be operated and opened respectively.

[0048] like Figure 2 , Figure 3 As shown, the box body 14 is provided with tracks 020, 021, 022, and 023 for the rotation of the microwave radiation separation barrel 20 and the multi-stage screening barrel. Balls 17 that can slide and rotate along the tracks are provided on one side of the tracks connecting the microwave radiation separation barrel 20 and the multi-stage screening barrel to the inner wall of the box body 14. Brushes are provided at the connection points of the balls 17 to prevent impurities or dust from entering the gap between the tracks and the balls and affecting the rotation of the components. In addition, the microwave radiation separation barrel 20 has the same connection method between the balls and the tracks as mentioned above at the bottom 19 of the outer cylinder.

[0049] The heat preservation layer of the box body 14 is made of heat preservation materials that do not absorb microwaves, and all materials are high temperature resistant materials.

[0050] The following is a processing method using the above-mentioned equipment, comprising the following steps:

[0051] S101: Construction waste enters the microwave radiation separation barrel 20 from the feed inlet 4;

[0052] S102: When the height of the construction waste in the microwave radiation separation barrel 20 reaches the minimum workload, the microwave trigger 9 is triggered, and the microwave generation control system 7 starts to work, so that the microwave guide port 27 emits microwaves, and the construction waste is radiated by microwaves and starts to heat up. At the same time, the first-stage motor 5 is turned on, and the microwave radiation separation barrel 20 starts to rotate, and the steel brush 15 axis system also rotates together to clean the sieve holes, so that each barrel works efficiently. Aggregates that meet the particle size standard fall into the large particle storage barrel 21 through the sieve holes of the microwave radiation separation barrel 20;

[0053] S103: The microwave radiation separation barrel 20 and the large particle storage barrel 21, the small and medium particle storage barrel 22, and the impurity barrel 23 are driven by different motors. When the construction waste in the large particle storage barrel 21 reaches a certain amount, the second-stage motor 24 is turned on, and the large particle storage barrel 21, the small and medium particle storage barrel 22, and the impurity barrel 23 start to work. The rotation speed can be adjusted manually. Under the action of the guide fins 12 in each barrel and the sieve holes on the barrel wall, the particles in each barrel are graded and gradually accumulated toward the discharge port 18.

[0054] S104: When the construction waste at the discharge port 18 accumulates to a certain amount, the auxiliary discharge system 6 can assist the discharge port 18 to discharge aggregates of various levels;

[0055] S105: Toxic gases and dust that may be generated by heating the building aggregates in steps S101-S104 are discharged through the dust and toxic gas exhaust suction port 16 for treatment.

[0056] S106: During steps S101-S105, the temperature and pressure inside the box can be measured by the temperature and pressure measuring module 29. When the temperature is too high, the microwave generation control system 7 can be manually adjusted to reduce the microwave extraction energy or turn off the microwave, so as to save energy while ensuring the normal separation work in the microwave radiation separation barrel 20.

[0057] S107: In step S102, when the added construction waste reaches the maximum capacity, the microwave trigger 9 will sound an alarm to notify to stop adding construction waste.

[0058] S108: In step S104, the auxiliary cleaning system 6 may be a high-pressure jet system or a high-pressure water spray system. When necessary, the auxiliary cleaning system 6 may be opened in advance to remove impurities carried on the surface of aggregate particles.

[0059] The steps of this process do not affect each other and can be carried out simultaneously, in a flow line, for mechanized production. Matters not covered in this invention are known technologies.

[0060] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
