The second step, by means of the circumferential rotation of the grinding wheel 23 and the engagement of the toothed ring 13 and the gear 29, the rotating shaft 27 in the grinding wheel 23 is driven to carry the eccentric block 28 to rotate, so as to drive the grinding wheel 23 to vibrate and circumferentially rotate, the grinding effect of the grinding wheel 23 on the water quenching slag is assisted and strengthened, the water quenching slag crushed aggregates are continuously gathered and pushed by the inclined blanking scraper 26 to be guided, so that the crushed aggregates are guided to fall from the tray 21 and enter the grinding gap between the grinding turntable 24 and the grinding seat 22 to be ground into powder for the second time;
Thirdly, powder falling from an annular grinding gap between the grinding rotary table 24 and the grinding seat 22 falls to the top of a drying disc 31 above, a heating plate 32 in the drying disc 31 is electrified to heat the drying disc 31 so as to perform primary drying treatment on the powder, and a scraping plate 36 at the top of the drying disc is used for blocking and accumulating the powder on the drying disc 31 along with the rotation of the drying disc 31 until a discharging opening 33 is rotated to the position of the scraping plate 36, so that primary drying materials are scraped into a temporary storage discharging hopper 35;
Carrying out line type blanking onto a next-stage drying disc 31 through an elongated discharge hole at the bottom of a temporary storage blanking hopper 35, carrying out secondary uniform spreading and drying in cooperation with the rotation of a corresponding drying disc 31, repeating the blocking and accumulation of the powder by a scraping plate 36, carrying out multistage drying treatment in cooperation with a lower drying disc 31, and discharging the dried powder to the bottom of a crushing tower body 1, and then intensively discharging through a discharge pipe at the bottom of the crushing tower body 1;
in the multistage drying process, water vapor generated by drying powder in the crushing tower body 1 is extracted through a spiral pipe 310 and an external fan, in the extracting process, part of the powder which is pulled is blocked by a metal filter screen 38 to prevent overflow, the metal filter screen 38 is heated at intervals through a drying disc 31, the water vapor is prevented from being condensed into water vapor to be attached to the metal filter screen 38, when the water vapor is discharged through the spiral pipe 310, the internal heat of the water vapor is transferred to the crushing tower body 1 through the spiral pipe 310, the auxiliary preheating is carried out on water quenching slag in the crushing process, the drying efficiency and the quality of the powder are further improved, and the water vapor is lost to cause part of the condensed water vapor to fall into a liquid collecting box 311 for collection;
step five, in the rotation process of the drying disc 31, the metal filter screen 38 and the cam disc 37 are driven to synchronously rotate, the cleaning brush 315 on the matched scraping plate 36 cleans the annular side wall of the metal filter screen 38, the downward guide of the guide rod 314 is carried out through the cam disc 37, and the reset and the rising of the movable plate 313 after the downward movement are carried out through the spring 312, so that the reciprocating lifting movement of the movable plate 313 carrying the cleaning brush 315 is realized, the blockage of the metal filter screen 38 is effectively avoided, and the drying effect is poor due to the fact that water vapor is difficult to efficiently discharge.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
