Abstract

The utility model relates to a filter core for a lamination filter which comprises a core pipe and more than two filter membranes. Each filter membrane is in the shape of a regular n-gon, and each two adjacent filter membranes have an interval equal to 180 DEG/n angle and are sleeved on the core pipe in a stacking way. The filter core for the lamination filter adopting the technical proposal forms a triangular opening gap between each two adjacent filter membranes. Under the state of compression filter, when filter fluid passes through the filter core, the triangular gap of the filter core for the lamination filter can firstly filter coarse particles of the filter fluid to cause each coarse particle of the filter fluid to be segmented outsides multiple layers of filter membrane, thereby the buffer action is fulfilled on multiple layers of filter membrane, and then fine filtration is carried out through multiple layers of filter membrane, thereby the technical problem of filtration with multiple layers at the same time is solved, and the filter effect is strengthened.

Adopt the laminated filter filter core of technique scheme, because the laminated filter filter core comprises the core pipe, two above filtration membranes, filtration membrane is positive n limit shape, two adjacent filtration membranes concentric stacking of 180 °/n angle at interval are sleeved on the core pipe, such filter core, form the triangle open mouth slit at two adjacent filtration membranes, compressing under the filtration state, when filtering fluid through filter core, at first can once filter the coarse granule that filters fluid in the triangle slit of laminated filter filter core, the thick particle of filtration fluid is isolated in outside the multiple filtration diaphragm, the multiple filtration diaphragm is played a cushioning effect, and then carry out essence by the multiple filtration diaphragm and filter, solved the technical problem of multiple filtration simultaneously; Simultaneously, because filtration membrane adopts positive n limit shape, and two adjacent filtration membranes concentric stacking of 180 °/n angle at interval are sleeved on the core pipe, the shape of so simple change filtration membrane and mounting means, can prolong filter core and the linear area that contacts of filtering fluid, strengthen filter effect.

Further, for accuracy and the convenience that guarantees to install, core pipe and filtration membrane are carried out structural restriction, it is center circumferential a plurality of location groove that distributes that the surface of requirement core pipe is provided with the core tubular axis heart, and two adjacent location grooves are 180 °/n angle at interval, the filtration membrane upper inner ring is provided with and the corresponding positioning convex point of core pipe location groove, and the filtration membrane positioning convex point is stuck in the groove of core pipe location.Adopt the core pipe and the filtration membrane of this spline structure, when mounted, the 180 °/n angle of only need being separated by in turn is stuck in the filtration membrane positioning convex point in the groove of core pipe location, just can guarantee the accuracy of installing to make it easy for installation accurate.

Further, restriction concrete shape of filtration membrane and the installation angle of being separated by, the n limit shape of described filtration membrane is defined as regular hexagon or regular pentagon, adjacent 30 ° at two filtration membranes intervals or 36 ° of concentric stacking of angle are sleeved on the core pipe, and this is because in the shape of positive n limit, hexagon and pentagon are easy to process, and it is commonly used, can reach the filter core purpose of this structure, simplify the manufacturability of producing again, improve working (machining) efficiency.

Use the laminated filter filter core of technique scheme, can reach in use needs are filtered the fluid purpose of multiple times of filtration simultaneously, strengthened filter effect, improved the filter effect of whole filter.
