[0037] The filter screen 30 is fixed between the first material discharging end 12 and the second material feeding end 21, and the filter screen 30 is provided with a plurality of filter holes 31, so that the powder and particle materials can flow from the first material passing cavity to the second material passing cavity through the filter holes 31, and the impurities in the powder and particle materials can be filtered by the filter screen 30 and remain in the first material passing cavity.

[0038] The flowable area of the filter screen 30 is not less than the area of the first material feeding end 11 and the area of the second material discharging end 22, so as to ensure that the installation of the filtering device 100 does not affect the unloading rate of the powder and particle materials.
