(2) again due to the first filter membrane, the first and second retaining rings, and each sleeve forms together and take the first filter membrane as bottom surface and take the exhalant canal that each sleeve is delivery port, in every two such filter elements that this exhalant canal makes to stack together up and down, the plane rigidity block water plate that the first filter membrane of the filter element below being positioned at can not be positioned at the filter element of its top directly contacts, but gapped, therefore this exhalant canal just provides enough flushing spaces for rinsing the dirt remaining in the first filter membrane surface, making to clean dirt is more prone to.Than the direct close contact each other of filter element in prior art rolled film, this effect is apparent.
(3) when the first filter screen is made as double-layer structure, and when this double-layer structure consists of ground floor filter screen and second layer filter screen, when even the pressure that puts on the first filter membrane when water to be filtered causes the first filter membrane to cave in to stop up ground floor filter screen, second layer filter screen can be because the depression of filter membrane is stopped up, thereby the unobstructed aquaporin of adopting still can be provided.
For filter element in the present invention adopt take plane rigidity block water plate, stack gradually the first filter screen and the first filter membrane in block water plate the first side and stack gradually the situation that the second filter screen and the second filter membrane in block water plate the second side are stack of laminations:
(1) now, the first filter membrane and the second filter membrane are as the filter membrane of exhalant canal in filter element, no matter water to be filtered (having certain pressure) is to enter from the region between the first and second retaining rings of the first filter membrane, or enter from the second filter membrane, when this filter element filters, residual dirt all remains on the surface of the first filter membrane or remains on the surface of the first and second filter membranes, and cannot remain on the first filter screen and the second filter screen, be therefore convenient to clean dirt.
(2) because the first filter membrane, the first and second retaining rings and each sleeve form together, take the first filter membrane as bottom surface and take the exhalant canal that each sleeve is delivery port again, this exhalant canal is the exhalant canal in this filter element,, filter membrane between its every two such filter elements that make to stack together up and down by exhalant canal spaced apart (being that is gapped rather than direct contact).Therefore, this exhalant canal can provide enough flushing spaces for rinsing the dirt remaining in the first filter membrane surface and the second filter membrane surface, makes to clean dirt and is more prone to.
(3) because filter element has stacked gradually the first filter screen and the first filter membrane in the first side of rigidity block water plate, the second side at rigidity block water plate has stacked gradually the second filter screen and the second filter membrane, thereby water to be filtered (having certain pressure) can filter respectively from the first filter membrane and the second filter membrane respectively, this increases the filter ability of filter element, and correspondingly the filter capacity of filtering tank increases.
(4) when the first filter screen and the second filter screen are made as double-layer structure, and when this double-layer structure forms by ground floor filter screen and second layer filter screen, even when water applied pressure to be filtered causes the first and second filter membranes to cave in to stop up the ground floor filter screen of the first filter screen and the second layer filter screen of the second filter screen, the second layer filter screen of the two all can not stop up due to the depression of filter membrane separately, thereby the unobstructed aquaporin of adopting still can be provided.
