Detailed Description

The following describes an embodiment of the present invention with reference to fig. 1 to 4.

Figure 1 illustrates the location where the screening device is mounted on a crusher, the screening device comprising: the magnetic screening component 2 is arranged on the activated carbon crusher 1, the magnetic screening component 2 is arranged below the feeding hopper 11 and above the crushing roller 12, and is used for removing doped scrap iron before the activated carbon blocks are crushed; an iron scrap collecting box 3 is arranged below the magnetic screening component 2, and a scrap scraping combination plate 4 penetrating through the drawer frame 23 from top to bottom is arranged on the side where the drawer frame 23 is pulled out.

FIG. 2 illustrates the overall structure of a magnetic screen assembly, magnetic screen assembly 2 having the plurality of magnetic bars 21 disposed thereon; the magnetic rod 21 is fixed in a drawer-shaped drawer frame 23, a handle 22 is installed outside the drawer frame 23, the handle 22 pulls the drawer frame 23 to move along the length direction of the magnetic rod 21, and the magnetic rod generates a magnetic field of at least 3000 gauss.

Fig. 3 illustrates an arrangement of the magnetic rods, and the magnetic rods 21 are at least arranged in upper and lower rows and are alternately arranged.

Fig. 4 illustrates the constitution and scrap scraping manner of the scrap scraping assembly plate, and the scrap scraping assembly plate 4 includes: an upper scraper 41 mounted on the crusher 1 through a fixing hole 44, and a lower scraper 42 mounted inside the scrap iron collecting box 3 through a fixing hole 44; the upper scraper 41 and the lower scraper 42 are connected on the axes of the two rows of magnetic rods 21, a semicircular opening 43 is arranged at the connection part, the semicircular opening 43 is clamped on the excircle of the magnetic rod 21, and when the drawer frame 23 is pulled outwards, the upper scraper 41 and the lower scraper 42 together scrape iron filings adsorbed on the excircle of the magnetic rod 21 and fall into the iron filings collecting box 3
