The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1-4,9-11, the self-cleaning combined filtration of high speed mechanism, this mechanism is made up of cylindrical outer filter mantle 1, cylindrical interior overcurrent cover 5 and intermediate filtered dielectric layer 4, be distributed with monolateral curve slit 6 on the outer filter mantle 1, the edge line of curve slit 6 is a curve, and its curvilinear equation and Archimedes spiral equation are approaching; Be distributed with combination bore 9 on the interior overcurrent cover 5, every group of combination bore 9 is made up of a centre bore 2 and five foliaceous curved slots 3, five curved slots 3 are around centre bore 2 shape distribution in the shape of a spiral, and the edge line of curved slot 3 is the curve of two sections closures, and its curvilinear equation and Archimedes spiral equation are approaching; Intermediate filtered dielectric layer 4 is made of two-layer water conservancy diversion net and filter medium, and filter medium is multiple filtration net, metal silk flosssilk wadding, quartz sand, polymeric particles or its assembly.
As Fig. 5-8,9-11, the self-cleaning combined filtration of high speed mechanism, this mechanism is made up of cylindrical outer filter mantle 10, cylindrical interior overcurrent cover 5 and intermediate filtered dielectric layer 4, be distributed with bilateral curve slit 7 on the outer filter mantle 10, the edge line of curve slit 7 is a curve, and its curvilinear equation and Archimedes spiral equation are approaching; Be distributed with combination bore 9 on the interior overcurrent cover 5, every group of combination bore 9 is made up of a centre bore 2 and five foliaceous curved slots 3, five curved slots 3 are around centre bore 2 shape distribution in the shape of a spiral, and the edge line of curved slot 3 is the curve of two sections closures, and its curvilinear equation and Archimedes spiral equation are approaching; Intermediate filtered dielectric layer 4 is made of two-layer water conservancy diversion net and filter medium, and filter medium is multiple filtration net, metal silk flosssilk wadding, quartz sand, polymeric particles or its assembly.
