Abstract
The utility model provides a reciprocating pressure backwash anti-blocking filter comprising upper and lower substrate layers. A rubber layer is disposed between the two substrate layers to form a stack structure. The upper and lower substrate layers are formed by a material having a certain strength and a hardness, e.g., Feilin film. The filter not only overcomes the difficulty of drilling a large opening, but also, each opening after driving can be narrowed to a certain extent according to a proportion so as to generate friction to a probe. Moreover, the stack structure is firm and can be taken as a layer of independent assembly. The filter is easily assembled and thus is suitable to replace the existing product which can be widely applied.
Claims3
