As a modification of the present invention, described cylinder and enhancement Layer lower floor junction are fillet.
As a modification of the present invention, described filter bag thickness is 0.5-1mm.
As a modification of the present invention, described enhancement Layer upper strata diameter is identical with described flange.
As a modification of the present invention, the mesh of described enhancement Layer lower floor screen pack is 0.3-0.6mm.
As a modification of the present invention, the mesh of described filter bag is 0.02-0.05mm.
As a modification of the present invention, the mesh of described filter vat is 0.1-0.3mm.
The invention has the beneficial effects as follows:
Structure of the present invention is simple, convenient and practical, corrosion-resistant, and adopt three layer filtration, good filtration effect, and be crushed between stainless steel cylinder and filter vat above filter bag, shock-resistant, protect the place that filter bag is easily bad, service time is long.
