The vibrating table 2 is installed on the top of the screening frame 1, and the feeding port 3 is installed at the end of the vibrating table 2. The side wall of the vibrating table 2 is provided with a through-hole groove 6. A mounting plate 4 is movably inserted into the inner cavity of the through-hole groove 6. A mounting groove 11 is provided on the surface of the mounting plate 4. A filter screen 5 is fixed to the inner cavity of the mounting groove 11 on the surface of the mounting plate 4 by bolts.

[0029] It should be noted that the feed pellets are fed through the feeding port 3. The feed pellets first fall onto the surface of the upper filter screen 5. Under the action of vibration, the small feed pellets fall onto the lower filter screen 5, and then the lower filter screen 5 continues to screen the feed pellets. The smaller particles and debris that are screened off fall to the bottom of the inner cavity of the vibrating table 2, thus achieving the screening of the feed pellets. The two sides of the vibrating table 2 are provided with insertion grooves 6. The mounting plates 4 are respectively inserted into the insertion grooves 6. The filter screen 5 is fixed in the mounting grooves 11 on the surface of the mounting plates 4 by bolts. The fixing clamp 7 is inserted into the fixing screw 10 through the mounting hole 9.

[0032] In this embodiment, as Figure 1 As shown, a dust collection hood 13 is installed on the top surface of the vibration table 2. The dust collection hood 13 is located on one side of the feeding port 3. The upper surface of the dust collection hood 13 is connected to the slag storage bucket 14 through a dust suction pipe. A dust removal filter bag 16 is movably installed in the inner cavity of the slag storage bucket 14. A suction pump 15 is installed on the side wall of the slag storage bucket 14.

The smaller particles and debris that are screened off fall to the bottom of the inner cavity of the vibration table 2. Under the action of vibration, the particles at the bottom of the inner cavity of each filter screen 5 and the vibration table 2 move forward and are discharged through the discharge port 12. During the screening process, the vibration causes the dust in the feed pellets to fly up. The dust is collected by the suction pump 15 in conjunction with the dust collection hood 13.
