[0042] It should be particularly emphasized that a method for using a plate processing waste treatment device includes the following steps:

[0043] Step 1: After the waste is screened by the pre-screen plate 12, it enters the crusher 11 for crushing;

[0044] Step 2: After screening and crushing, the waste falls to the conveying unit 2 and is transported centrally by the main conveyor belt 21. During the centralized transportation, the waste passes under the dust removal unit 3 for dust removal.

[0045] Step 3: The dust-removed waste is transported by the main conveyor belt 21 to the metal separation unit 4 and passes through the permanent magnetic roller 41. The metal impurities in the waste are adsorbed by the permanent magnetic roller 41 and separated from the waste;

[0046] Step 4: After metal separation, the waste reaches the diversion screen plate 241 and is further screened into two different specifications of large and small, and is collected separately.

[0047] Working principle: First, start the plate processing waste treatment device, put the waste to be recycled at the entrance of the crusher 1, and a pre-screen plate 12 is provided at the entrance of the crusher 1. The pre-screen plate 12 screens out the waste that meets the specifications, and the waste that meets the specifications falls into the branch channel 114 formed between the baffle 113 and the casing 11, and directly reaches the main conveyor belt 21. The waste that does not meet the specifications is blocked by the pre-screen plate 12 and enters the crusher 1;

[0048] Then, the waste materials that do not meet the specifications enter the crusher 11 and are crushed by the crushing toothed disc 141 to meet the recycling specifications. The qualified waste materials after crushing fall from the crusher 11 and fall onto the main conveyor belt 21. The processed waste materials are transported to the right by the main conveyor belt 21 and pass under the dust removal unit 3. The dust generated during the crushing process is collected and processed by the dust removal unit 3.

[0049] Then, the processed waste is transported to the right end of the main conveyor belt 21 through the main conveyor belt 21, and falls from between the main conveyor belt 21 and the permanent magnetic roller 41. When passing through the permanent magnetic roller 41, the metal impurities mixed in the waste are adsorbed on the surface of the roller by the permanent magnetic roller 41. The permanent magnetic roller 41 rotates continuously so that the metal impurities adsorbed on the surface of the roller are scooped off by the separation shovel 421 close to the permanent magnetic roller, and the metal impurities scooped off by the separation shovel 241 fall into the collection bucket 42.

[0050] Finally, the waste that has been processed by metal separation falls onto the diverter sieve plate 241. After further screening by the diverter sieve plate 241, the processed waste is screened into two specifications, larger and smaller. The larger waste falls along the diverter sieve plate 241 onto the second diverter conveyor belt 25, and the smaller waste passes through the diverter sieve plate 241 and falls onto the first diverter conveyor belt. Through the first diverter conveyor belt 23 and the second diverter conveyor belt 25, the smaller waste and the larger waste are collected and processed separately.
