[0035] The working principle of the above embodiment is as follows:

[0036] (1) By opening the funnel cover, the hazardous waste to be processed can be poured into the inside of the crushing box 1 through the feed funnel 21. The motor 4 can drive the movable shaft 5 and the driving gear 6 to rotate in sequence. Since the driving gear 6 meshes with the transmission gear 7, during the rotation of the driving gear 6, the transmission gear 7 and the connecting shaft 8 will be driven to rotate in sequence. During the rotation of the movable shaft 5 and the connecting shaft 8, the two crushing rollers 9 will be driven to rotate relatively. When the two crushing rollers 9 rotate relatively, the hazardous waste can be crushed. The crushed hazardous waste will fall above the guide plate 10 and then slide into the inside of the collection box 16 for collection, achieving the purpose of crushing and collecting hazardous waste.

[0037] (2) The driving motor 11 can drive the threaded rod 12 to rotate. Since the threaded rod 12 is threadedly connected to the threaded push block 13, during the rotation of the threaded rod 12, the threaded push block 13, the movable push plate 14 and the movable pressing block 15 will be driven to move up and down in sequence. During the up and down movement of the movable pressing block 15, the hazardous waste inside the collection box 16 can be flattened, thereby strengthening the quantity and effect of the collection box 16 on collecting hazardous waste.

[0038] (3) When it is necessary to fix the collection box 16 inside the crushing box 1, first open the movable door 22 and place the collection box 16 in the fixed square groove inside the crushing box 1 for preliminary positioning. Then, the electric push rod 17 can drive the movable clamping block 18 to move to the right. During the movement of the movable clamping block 18 to the right, the collection box 16 can be clamped and fixed in cooperation with the fixed clamping block 19, avoiding the phenomenon that the collection box 16 shakes or deviates during the process of collecting hazardous waste, so as to ensure the effect of the collection box 16 on collecting hazardous waste.

[0039] (4) When it is necessary to take out the collection box 16 from the inside of the crushing box 1, first open the movable door 22, and then the electric push rod 17 can drive the movable clamping block 18 to move leftward. During the process of the movable clamping block 18 moving leftward, it will separate from the collection box 16, causing the collection box 16 to lose its limit. Thus, the collection box 16 can be carried out from the inside of the crushing box 1 by grasping the two fixed handles, so as to facilitate the cleaning of the hazardous waste inside the collection box 16.

[0040] Compared with the prior art, the overall structure is simple and convenient to use, achieving the purpose of facilitating the compaction of hazardous waste. After the treatment device crushes the hazardous waste, it can be flattened, which can ensure the quantity and effect of the crushing and collection of hazardous waste by the treatment device. It does not require the staff to clean frequently, reducing the labor intensity of the staff, improving the efficiency of the treatment device for crushing hazardous waste, and meeting the actual use requirements.
