[0034] In this embodiment, the inner cavity of the processing box 1 is in a cylindrical shape. When the rotating rod 3 rotates, the rotating rod 3 drives the plurality of cutting knives 4 to rotate around the rotating rod 3, and the low-smoke halogen-free flame-retardant polyolefin cable material in the processing box 1 is cut into particles. The filtering assembly 5 filters the low-smoke halogen-free flame-retardant polyolefin cable material. The larger particles of the low-smoke halogen-free flame-retardant polyolefin cable material are located on the top of the filter screen 8. The two electric push rods 10 are started. The moving end of the electric push rod 10 drives the connecting plate 9 to move vertically. Under the connection of the filtering ring 6, the filter screen 8 lifts the larger particles of the low-smoke halogen-free flame-retardant polyolefin cable material, so that the low-smoke halogen-free flame-retardant polyolefin cable material is in full contact with the plurality of cutting knives 4, thereby improving the cutting quality of the low-smoke halogen-free flame-retardant polyolefin cable material. At the same time, by lifting the low-smoke halogen-free flame-retardant polyolefin cable material, the low-smoke halogen-free flame-retardant polyolefin cable material is prevented from blocking the filter screen 8. The filtering ring 6 provides support and fixing for the filter screen 8. When the filtering ring 6 moves vertically, the circular scraper 7 is driven to remove the low-smoke halogen-free flame-retardant polyolefin cable material adhering to the inner wall of the processing box 1, thereby improving the cutting quality of the low-smoke halogen-free flame-retardant polyolefin cable material.

[0041] Specifically, the end surface of the conduit 21 penetrates the top wall of the cleaning box 24 and is communicated with a hollow mounting plate 22, the top surface of the mounting plate 22 is provided with a plurality of nozzles 23, the side surface of the cleaning box 24 is provided with a liquid inlet 25 and a liquid outlet 26, and the bottom of the processing box 1 is connected with four arrayed supporting rods 15.

[0042] In this embodiment, under the communication effect of the conduit 21, the toxic gas is introduced into the inner cavity of the mounting plate 22, and then is sprayed out through the plurality of nozzles 23.

The liquid inlet 25 and the liquid outlet 26 are provided to introduce and discharge the treatment liquid in the cleaning box 24, and the liquid inlet 25 and the liquid outlet 26 are both provided with electromagnetic valves. The gas introduced into the cleaning box 24 is discharged through the liquid inlet 25, and the liquid level of the treatment liquid in the cleaning box 24 is lower than that of the liquid inlet 25, providing conditions for the discharge of the gas.
