Detailed implementation mode
[0017] Please refer to Figures 1 to 3 In the embodiment of the present utility model, a dust removal device for a concrete structure wall brick recycling crusher includes a crusher box 1. A feed input pipe 2 is connected to the top of the crusher box 1. The feed input pipe 2 is bent, and the upper end of the feed input pipe 2 is horizontally arranged. A feed conveyor belt 3 is arranged at the opening of the upper end of the feed input pipe 2, and the feed conveyor belt 3 extends into the interior of the feed input pipe 2. A dust recovery mechanism is arranged between the feed input pipe 2 and the crusher box 1.
[0018] Preferably, the dust recovery mechanism includes a transfer box 8. The transfer box 8 is located outside the crusher box 1. A fan 7 is connected to the upper end of the transfer box 8. The input end of the fan 7 is connected to a dust collection pipe 6. The end of the dust collection pipe 6 is connected to a dust collection nozzle 5. The dust collection nozzle 5 is connected to the surface of the bent part of the feed input pipe 2, and the interior of the feed input pipe 2 and the interior of the dust collection nozzle 5 are interconnected. The lower end of the transfer box 8 is connected to a discharge pipe 9. The lower end of the discharge pipe 9 communicates with the interior of the crusher box 1. An electric valve 10 is installed on the surface of the discharge pipe 9.
[0019] Preferably, a branch pipe 11 is fixedly connected to the upper end of the side wall of the transfer box 8. The branch pipe 11 and the interior of the transfer box 8 are interconnected. A filter 12 is installed at the upper end of the branch pipe 11.
[0020] Preferably, a mesh plate 18 is installed inside the dust collection nozzle 5.
[0021] Preferably, a gear box 15 is fixedly connected to the top surface of the crusher box 1. A crushing motor 4 is fixedly installed on the outer surface of the gear box 15. The driving end of the crushing motor 4 penetrates through the gear box 15 and extends into the interior of the crusher box 1. The driving end of the crushing motor 4 is fixedly connected with a driving gear 16 and an active crushing roller 13 respectively. The driving gear 16 is located inside the gear box 15, and the active crushing roller 13 is located inside the crusher box 1. An auxiliary crushing roller 14 is rotatably arranged inside the crusher box 1. A driven gear 17 is connected to the shaft part of the auxiliary crushing roller 14. The driven gear 17 extends into the interior of the gear box 15, and the driven gear 17 meshes with the gear box 15.

The waste of the concrete structure wall brick is transported into the interior of the feeding input pipe 2 through the feeding conveyor belt 3, and then is crushed by the active crushing roller 13 and the auxiliary crushing roller 14. When discharging, the blower 7 needs to be turned on to generate suction at the dust collection nozzle 5. At this time, a negative pressure will be formed inside the feeding input pipe 2, and the dust formed when the waste is discharged from the surface of the feeding conveyor belt 3 will be sucked away by the dust collection nozzle 5, which can avoid the diffusion of dust during discharging. And due to the blocking of the mesh plate 18, small pieces of waste can be prevented from entering the interior of the dust collection nozzle 5. The absorbed dust will be stored in the transfer box 8 first. Since the side wall of the transfer box 8 is connected with a branch pipe 11, and the top of the branch pipe 11 is connected with a filter 12, the pressure inside the transfer box 8 can be ensured, and at the same time, the dust can be prevented from diffusing to the outside. After the crushing is completed, when the electric valve 10 is opened, under the action of gravity, the dust will be discharged into the interior of the crusher box 1.
