[0027] A dust hood 20 is provided at the top of the inner cavity of the crushing box 1 , and the dust hood 20 is connected to a dust collector 19 located at the top of the crushing box 1 . When the dust collector 19 is started, the dust generated in the crushing box 1 is absorbed through the dust hood 20 .

[0028] A compression assembly is provided at the discharge port of the crushing box 1, and the compression assembly includes a box body 9. A rotatable conveyor belt 10 is installed at the bottom of the inner cavity of the box body 9, and a liftable second cylinder 12 is provided above the conveyor belt 10. A pressing hammer 13 is installed at the free end of the second cylinder 12, and the pressing hammer 13 is located in the middle position of the box body 9. Two groups of rotatable screw rods 14 are also longitudinally arranged in the inner cavity of the box body 9. Two groups of molds 15 that can move forward and backward are installed on the screw rods 14 in threaded cooperation, and the molds 15 are located below the pressing hammer 13.

[0029] The mold 15 is located below the discharge port of the shaftless screw conveyor 7, and the feed belt 10 is located below the mold 15. The mold 15 includes a mold box 151 that passes through from top to bottom. The bottom of the mold box 151 is provided with an openable mold bottom plate 153, and the outer side of the mold box 151 is provided with a third cylinder 152, and the free end of the third cylinder 152 is connected to the mold bottom plate 153.

[0030] The discharge port of the compression assembly is provided with a lifting frame 16, on which a rotatable lifting belt 17 is installed, and on which a plurality of partition plates 18 are provided. The partition plates 18 can support the hazardous waste and prevent it from slipping.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in this field.

[0032] When in use, first place the ton bag on the feeding conveyor belt 3, and drive the feeding conveyor belt 3 to rotate by an external motor, so as to transport the ton bag to the crushing box 1, and the ton bag falls on the crushing knife group 4, and the crushing knife group 4 is driven to rotate by an external motor, so as to crush the ton bag. To facilitate crushing, the first cylinder 5 can be started first to drive the blade 6 to descend and cut the outer packaging bag of the ton bag, so that the hazardous waste can better contact with the crushing knife group 4.

[0033] After that, the crushed hazardous waste falls on the shaftless screw conveyor 7, and the motor 8 is started to drive the shaftless screw conveyor 7 to rotate, thereby conveying the hazardous waste to the box 9, and the hazardous waste falls into one of the molds 15 below, and then the second cylinder 12 is started, and the hazardous waste in the mold 15 is compressed and formed by the pressing hammer 13, and then the screw rod 14 is driven to rotate by the external motor, thereby driving another empty mold 15 to move to the unloading port of the shaftless screw conveyor 7 to continue to receive the material. The two molds 15 can alternately receive and discharge the material, and then the third cylinder 152 is turned on to drive the two mold bottom plates 153 to open, thereby opening the bottom opening of the mold 15, and the formed hazardous waste directly falls on the conveyor belt 10 below to be transported out.

[0034] Finally, the hazardous waste in sections is transported to the kiln mouth by the lifting belt 17 and directly enters the kiln.

[0035] To sum up, the hazardous waste ton bag pretreatment system can automatically feed the ton bag into the crushing box by setting up a feeding mechanism. The crushing knife group and blades inside the crushing box can cut the ton bag open and crush it to make its size more uniform. Furthermore, by setting up a compression component, the crushed hazardous waste can be compressed, which is convenient for feeding into the cement kiln, while also reducing the hazard of dust. Finally, the hazardous waste pieces are directly put into the cement kiln through the lifting mechanism. The whole process is basically automated, which reduces the workload of workers and improves efficiency.
