The raw materials placed on the filtering mechanism can be flattened by a brush and the raw materials are always kept in an active state, without the need to manually shake the sieve for screening, and do not rely on manpower, thus reducing manpower expenses.

The vibration motor 15 is started to generate vibration, which drives the vibration plate 3 and the bottom frame 4 and the filter frame 5 above it to vibrate together, so as to perform vibration screening on the metal catalyst. Since the filter holes of the plurality of filter frames 5 are different in size, the filter frame 5 with a small filter hole is placed at the bottom, and the filter frame 5 with a large filter hole is placed at the top, thereby achieving screening of metal catalysts of different particle sizes.

The fixed shaft 8 is connected to the rotating shaft 9, so that the lever 10 on the rotating shaft 9 rotates, the material inside the filter frame 5 is moved, and the filtering of the material is accelerated. Since the rotating shaft 9 is connected end to end, it is ensured that the lever 10 in each filter frame 5 can be driven by the driving motor 7.
