Due to the serious pollution and potential serious impacts caused by hazardous waste, and the fact that solid hazardous waste is large in size and difficult to degrade by itself under natural conditions, it is necessary to use corresponding crushing equipment to crush hazardous waste for subsequent centralized treatment. At present, most of the hazardous waste treatment is completed by a separate set of crushing rollers, but a single crushing operation cannot completely crush the hazardous waste, and there is a situation of insufficient crushing. Afterwards, the incompletely crushed hazardous waste must be manually screened, collected and crushed for the second time, which is very cumbersome. Therefore, a crushing system for hazardous waste disposal that can realize automatic secondary crushing is developed. Utility Model Content

DETAILED DESCRIPTION

[0015] like Figure 1-Figure 2 As shown, a crushing system for hazardous waste disposal includes a cylindrical barrel 1, two vertical support legs 2 are symmetrically fixedly installed at the lower part of the barrel 1, and a storage bin 3 is fixedly installed between the two support legs, and a discharge port 4 is arranged at the bottom of the storage bin 3. A long strip screening trough 5 is opened at the bottom of the barrel 1 above the storage bin 3, and a screen 6 is installed inside the screening trough 5.

[0016] A rotating shaft 7 coinciding with the axis of the cylinder 1 is rotatably installed inside the cylinder 1 , and a first motor 8 for driving the rotating shaft 7 to rotate is installed at one end outside the cylinder 1 . A spiral blade 9 is sleeved on the peripheral wall of the rotating shaft 7 .

[0017] A feed crushing bucket 10 connected to the inside of the cylinder 1 is fixedly installed at one end of the upper part of the cylinder 1 near the first motor 8, and two first crushing rollers 11 are symmetrically rotated and installed inside the feed crushing bucket 10. A second motor 12 for driving the two first crushing rollers 11 to rotate relative to each other is installed outside the feed crushing bucket 10. Specifically: the driving shaft of the second motor 12 is connected to one end of the central axis of one of the first crushing rollers 11, and one end of the central axis of the two first crushing rollers 11 away from the second motor 12 extends to the outside of the feed crushing bucket 10 and is equipped with two meshing first gears 13.

[0018] The bottom of the cylinder 1 is provided with a material transfer port 14 at the end away from the first motor 8. Two second crushing rollers 15 are symmetrically mounted in the interior of the storage bin 3 below the material transfer port 14. A third motor 16 for driving the two second crushing rollers 15 to rotate relative to each other is mounted outside the storage bin 3. The driving shaft of the third motor 16 is connected to one end of the central axis of one of the second crushing rollers 15. The ends of the central axes of the two second crushing rollers 1 away from the third motor 16 extend to the outside of the storage bin 3 and are equipped with two meshing second gears 17.

[0021] The solid hazardous waste to be crushed is put into the feed crushing bin, and the second motor drives the two first crushing rollers to rotate relative to each other to complete the primary crushing of the solid hazardous waste, and the solid hazardous waste after the primary crushing enters the cylinder. The first motor drives the rotating shaft to rotate, and under the action of the spiral blades rotating with the rotating shaft, the solid hazardous waste after the primary crushing is transported to the transfer port by the feed crushing bucket in a spiral conveying manner. In this process, the spiral blades can also stir the solid hazardous waste after the primary crushing, and the hazardous waste fragments that meet the crushing specifications will fall through the screen of the screening trough and enter the storage bin; the large pieces of uncrushed solid hazardous waste sent to the transfer port are discharged from the transfer port to the cylinder. The third motor drives the two second crushing rollers to rotate relative to each other to complete the secondary crushing of the solid hazardous waste, thereby ensuring the crushing effect. The crushed fragments also enter the storage bin and are discharged from the discharge port together with the fragments leaking from the screen.
