[0042] Working principle: The present invention uses a multi-stage screening device to grade the crushed petroleum coke to achieve accurate separation and classified storage of products with different particle sizes; the present invention adopts a modular sieve plate structure and is equipped with a quick replacement mechanism, which can achieve the switching of sieve plates with different apertures without stopping the machine, significantly improving the screening operation efficiency; the present invention integrates a humidity sensing unit, which can adjust the feed inclination controller in real time according to the moisture content of the petroleum coke material to optimize the material flow characteristics; in addition, the present invention is equipped with a dust collection and recovery device, which can effectively collect the fine powder materials generated during the screening process to achieve full process control of the materials; the grading processing system has the characteristics of high degree of automation, stable operation, strong adaptability, etc., and can meet the production needs of petroleum coke products of different specifications; The semi-processed petroleum coke is manually poured onto the conveyor belt mechanism 101, and then poured into the rectangular frame 102 through the conveyor belt mechanism 101. The humidity of the petroleum coke dropped from the conveyor belt mechanism 101 into the rectangular frame 102 is detected by the humidity sensor on the side of the rectangular frame 102, so as to adjust the inclination angle of the shielding plate 103 according to the humidity of the petroleum coke; the shielding plate 103 is driven to rotate by the expansion and contraction of the first electric cylinder 104, so as to open the shielding plate 103 and let the petroleum coke in the rectangular frame 102 flow into the square frame 210; The crushed petroleum coke needs to be graded to separate products of different particles, in order to quickly grade the petroleum coke according to its particle size; The rotating circular plate 209 is driven to rotate by the second motor 208, so that the slide groove on one side of the rotating circular plate 209 drives the small round rod 217 to drive the square frame 210 to move. Since the limit plate on the side of the square frame 210 is slidably installed in the rectangular slide groove on the side of the side bracket 207, the square frame 210 can only move up and down, and two first screw assembly mechanisms 212 and four groups of fixed bottom plate structures are installed on the square frame 210, and the second filter plate 211 is clamped under the square frame 210 by the four groups of fixed bottom plate structures, so the square frame 210, the second filter plate 211, the two first screw assembly mechanisms 212 and the four groups of fixed bottom plate structures all move up and down, thereby screening the petroleum coke inside the square frame 210; The working principle of the fixed bottom plate structure is as follows: the motor on one of the first screw assembly mechanisms 212 drives the screws of the two first screw assembly mechanisms 212 to rotate, thereby driving the longitudinal slide slot frame 213 on the same side to move, thereby driving the L-shaped plate 215 and the electric wheel 216 to move along the slide slots of the arc-shaped slide slot frame 214 and the longitudinal slide slot frame 213, thereby loosening the second filter plate 211; When replacing one of the first filter plates 206 with different aperture sizes, first, the motor on one of the first screw assembly mechanisms 212 drives the screws of the two first screw assembly mechanisms 212 to rotate, thereby driving the longitudinal slide slot frame 213 on the same side to move, thereby driving the L-shaped plate 215 and the electric wheel 216 to move along the slide slots of the arc-shaped slide slot frame 214 and the longitudinal slide slot frame 213, thereby loosening the second filter plate 211; the motor on one of the second screw assembly mechanisms 303 drives the second screw assembly 214 to rotate, thereby driving the longitudinal slide slot frame 213 on the same side to move, thereby driving the L-shaped plate 215 and the electric wheel 216 to move along the arc-shaped slide slot frame 214 and the longitudinal slide slot frame 213, thereby loosening the second filter plate 211; The lead screw of the coupling mechanism 303 rotates, thereby driving the sliding block 305 to move horizontally. During the movement of the sliding block 305, since the sliding block 305 is connected to the connecting slider 310 through the connecting long rod 306, and the connecting slider 310 is slidably connected to the second horizontal protruding long plate 309, and the second horizontal protruding long plate 309 is slidably matched with the longitudinal protruding plate 307, when the sliding block 305 moves, it will drive the connecting slider 310 to move along the L-shaped sliding groove on the large L-shaped support plate 302, first moving upward, and then moving horizontally, so that the suction cup The second filter plate 211 is moved to the bottom of the second filter plate 211, and then the second electric cylinder 315 is extended to drive the rectangular plate 316 and the suction cup 317 to move upward, so that the suction cup 317 adsorbs the second filter plate 211, and then returns horizontally again. When the first limiting disc 312 and the second limiting disc 313 move to the bending part of the L-shaped slide groove, the first limiting disc 312 and the second limiting disc 313 bend from the vertical state to the horizontal state, thereby driving the connecting rod 314, the second electric cylinder 315, and the rectangular plate 316 to move upward. 6 and the suction cup 317 are rotated to a certain extent, so that the suction cup 317 drives the second filter plate 211 to be pulled out from the bottom of the square frame 210, and then rotated to a certain angle, so that the second filter plate 211 is in a vertical state and faces the top of the collection box 6, so that the particles on the second filter plate 211 can be poured into the collection box 6, and then the second filter plate 211 is further cleaned manually to prevent the holes on the second filter plate 211 from being blocked, and then the second filter plate 211 is removed from the suction cup 317 manually; The first motor 203 drives the first rotating wheel 204 to rotate, thereby driving the first filter plate 206 to move toward the bottom of the square frame 210 to replace the position of the second filter plate 211. In order to ensure that the first filter plate 206 can quickly move to the bottom of the square frame 210, when the first filter plate 206 contacts the electric wheel 216, the electric wheel 216 will drive the first filter plate 206 to move until it is completely moved to the bottom of the square frame 210. Then, the cleaned second filter plate 211 is manually placed on the first filter plate 206 that has just been removed, thereby replacing plates with different apertures to filter petroleum coke. By replacing the positions of the two first filter plates 206 and the second filter plate 211 back and forth in this way, it is ensured that the apertures of these three plates will not be blocked. Therefore, the device is equipped with two first filter plates 206 and one second filter plate 211. The apertures of the two first filter plates 206 and the one second filter plate 211 are different in size, which is convenient for screening. When the first filter plate 206 is replaced, the four first rotating wheels 204 are driven to rotate by the first motor 203, so that the four first rotating wheels 204 push the first filter plate 206 to move. Finally, the filtered petroleum coke falls into the collecting frame 4 and the collecting bag 5. When the collecting bag 5 is full, the collecting bag 5 is taken away manually, and a new collecting bag 5 is put on the outlet of the collecting frame 4. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
