Description

Technical Field

The honeycomb ceramics obtained by this method have a simple structure and are prone to slag shedding during use; the pore size and distribution are highly random, resulting in poor consistency in filtration effect.

[0005] Preferably, reinforcing ribs are fixedly installed on the outer sides of both thin-walled rings.

[0006] Preferably, the outer diameter of the embedded porous funnel flow guiding structure is the same as the outer diameter of the cylindrical filter body, and the embedding depth of the embedded inner funnel is 1mm-3mm.

[0029] In use, the flow guiding components, along with the embedded porous funnel flow guiding structure 4 and its inner embedded hopper 401, enable flow guiding during the use of the filter 1.
