Detailed description of the invention
Referring to accompanying drawing, the specific embodiment of the invention is described below.
[the first embodiment]
Shown in Figure 1, in this embodiment, filter element comprises: stack of laminations, is formed by the plane rigidity block water plate 1, the first filter screen 2 and the first filter membrane 7 that stack gradually from top to bottom; Run through the first perforation 5 of stack of laminations, this first perforation 5 is as adopting water hole; The first retaining ring 6 and the second retaining ring 9, these two retaining rings are all layered on the first filter membrane 7, and the first retaining ring 6 is in the enclosing region of the second retaining ring 9; And first perforation 5 run through stack of laminations and be positioned at the enclosing region of the first retaining ring 6.
In the present embodiment, filter element has to accept the water receiving side of water to be filtered, and this water receiving side is exactly the region between the first and second retaining rings 6,9 of the first filter membrane 7.And the first filter screen 2 and the first filter membrane 7 expose from the internal perisporium of the first perforation 5, now the first filter screen 2 forms the first water transport channel flowing out from the first perforation 5 for the water after the first filter membrane 7 filters.
Therefore, in the time of filtered water, the lip-deep water of the first filter membrane 7 only has following unique flow path: after the first filter membrane 7 filters, enter the first filter screen 2, then flow into taking the first filter screen 2 as water transport channel in the first perforation 5, adopt water (obtaining the water after the first filter membrane 7 filters) to realize from the first perforation 5.Obviously, in the time filtering, residual dirt can only remain on the surface of the first filter membrane 7, and cannot remain on the first filter screen 2, is therefore convenient to clean dirt.In other words, in this embodiment, water to be filtered must first just can enter the first filter screen 2 after the first filter membrane 7 filters, and directly enters the first filter screen 2 and can not walk around the first filter membrane 7.
Further, rigidity block water plate 1 is in order to make this filter element have rigidity, and the multiple such filter elements of rigidity guarantee that have can stack gradually from top to bottom and use.As a kind of optimal way, rigidity block water plate 1 can be steel disc.
And, in Fig. 1, also show, on the periphery wall of the first retaining ring 6, be arranged with the first sealing ring 4, to prevent occurring that water leaks between the first retaining ring 6 and the first filter membrane 7; On the internal perisporium of the second retaining ring 9, be arranged with the second sealing ring 8, to prevent occurring that water leaks between the second retaining ring 9 and the first filter membrane 7.Should be appreciated that, the first retaining ring 6, the second retaining ring 9 can be all rigid members, for example, can be all steel ring; The first and second sealing rings can be for example silicon rubber loops.
In addition, aforementioned the first filter screen 2 can be single layer structure (example is as shown in Figure 1), but can be also sandwich construction.For example, the first filter screen 2 can be set to double-layer structure, is made up of ground floor filter screen stacked together and second layer filter screen.Particularly, ground floor filter mesh layer is stacked on block water plate 1, and the first filter membrane 7 is layered on second layer filter screen, and the mesh size of ground floor filter screen is greater than the mesh size of second layer filter screen.In brief, ground floor filter screen can be referred to as coarse net, second layer filter screen can be referred to as fine-structure mesh.Adopt the advantage of ground floor filter screen and second layer filter screen to be, even when the pressure that puts on filter membrane when water to be filtered causes 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 still can provide unobstructed water transport channel.
Obviously, in Fig. 1, rigidity block water plate 1 can be set to have the first wafer architecture of the first diameter, the first filter screen 2 and the first filter membrane 7 all can be set to have the second wafer architecture of Second bobbin diameter, wherein the first diameter is greater than Second bobbin diameter, and on rigidity block water plate 1, is provided with multiple fixing holes 3 of arranging around the first filter screen 2 and the first filter membrane 7.
Again, rigidity block water plate 1 has the first relative side and the second side, can think that a side that is laminated with the first filter screen 2 and the second filter membrane 7 of rigidity block water plate 1 is the first above-mentioned side.Now, can carry out improvement as described below to the first embodiment: in the second side of rigidity block water plate 1, stack gradually the second filter screen and the second filter membrane, and the second filter screen can be identical with the structure of structure, the second filter membrane and second filter membrane of the first filter screen.
[the second embodiment]
Referring to Fig. 2, the second embodiment of filter element of the present invention is described, this embodiment is the improvement of carrying out on the first embodiment basis, in Fig. 2, the parts identical with Fig. 1 are used label in Fig. 1, herein repeating label no longer.
The second embodiment is than the first embodiment, difference is: in the region between the first and second retaining rings 6,9, be provided with multiple the second perforation 17 that run through stack of laminations, each the second perforation is arranged with sleeve 10 in 17, and between the part of exposing from the second perforation 17 of the first filter screen 2 and sleeve 10 and be water-stop between the part of exposing from the second perforation 17 of the first filter membrane 7 and sleeve 10 and be connected.Now, the first filter membrane 7, the first and second retaining ring 6,9 and each sleeves 10, form the exhalant canal as bottom surface and taking each sleeve 10 as delivery port taking the first filter membrane 7 together.
In the time of filtered water, due to the existence of the first retaining ring 6 and the second retaining ring 9, because the water-stop between sleeve 10 and the part of exposing from the second perforation 17 of the first filter screen 2 is connected and because the water-stop between sleeve 10 and the part of exposing from the second perforation 17 of the first filter membrane 7 is connected, therefore, water to be filtered can only just can enter in the first filter screen 2 after the first filter membrane 7 filters, and can directly enter the first filter screen through the filtration of the first filter membrane 7.So residual soil can only be present on the first filter membrane 7 and can not be present in the first filter screen 2 when filtration; As for the part of not filtered by the first filter membrane 7 in water to be filtered, can in above-mentioned exhalant canal, flow due to the effect of hydraulic pressure, flow out finally by sleeve 10.The water flowing out from sleeve 10 both can drain as required, also can flow to another filter element and proceed to filter.Wherein said another filter element can be identical with filter element above-mentioned in this second enforcement.
And, above-mentioned exhalant canal is because the existence of the first and second retaining rings 6,9 has certain degree of depth, this degree of depth is exactly the height (under ideal situation, the height that these two retaining rings exceed the first filter membrane is identical) that the first and second retaining rings exceed the first filter membrane 7.Like this, exhalant canal just provides enough flushing spaces for flushing remains in the lip-deep dirt of the first filter membrane 7, further makes dirt be more prone to clean.
From Fig. 2, also can find out, for above-mentioned exhalant canal can, taking sleeve 10 as outlet, can be fixed on sleeve in the second perforation 17 as follows.Particularly, an axial end of each sleeve 10 is configured to be pressed on the first flanging on the first filter membrane 7, another axial end of each sleeve 10 is configured to be pressed on the second flanging on block water plate 1.And the first retaining ring 6 exceeds the height of the first filter membrane 7 and the second retaining ring 9 and exceed the height of the first filter membrane 7, all should be greater than the first flanging and exceed the height of the first filter membrane 7.Certainly, should be appreciated that, ensure the water-stop between the first flanging and the first filter membrane 7.
As for stack of laminations in the second embodiment, its formation is identical with stack of laminations in the first embodiment, just offers extraly the second perforation, and be provided with sleeve in the second perforation.
In addition, can also, by multiple these filter elements of being constructed as the second embodiment, be superimposed successively from top to bottom.For example, for example, for every two the such filter elements (the first and second filter elements) that superpose successively from top to bottom, the location between the first and second retaining rings in the first filter element of the first filter membrane in the first filter element, between the first filter membrane of the first filter element and the rigidity block water plate of the second filter element because the first and second retaining rings in the first filter element are spaced apart from each other instead of mutually directly contact., the exhalant canal becoming as front construction in the first filter element still exists.Thereby, even when filter element multiple as the second embodiment structure is superposeed up and down successively, than the situation very close to each other that is in direct contact with one another between filter element in the rolled film of prior art, the present invention still can clean easily and remain in the dirt on the first filter membrane in each filter element.
For the above-mentioned situation that multiple filter elements of being constructed as the second embodiment are superposeed from top to bottom successively, it should also be understood that: the first sealing ring of the first filter element should be able to ensure---between the first retaining ring of the-the first filter element and the rigidity block water plate of the second filter element, realize water-stop; The second sealing ring of the first filter element should be able to ensure---between the second retaining ring of the-the first filter element and the rigidity block water plate of the second filter element, realize water-stop.
In the second embodiment, the first filter screen can be identical with the first embodiment, can be both that single layer structure can be also sandwich construction.
It may be noted that in the second embodiment other structure and compositions of not describing in detail, identical with aforementioned description in the first embodiment, repeat no more.

When the side that stacks gradually the first filter screen 2 and the first filter membrane 7 with plane rigidity block water plate 1 is defined as the first side, when the opposite side relative with the first side of block water plate 1 is defined as to the second side, the 3rd embodiment is than the difference of the second embodiment: the 3rd embodiment has also stacked gradually the second filter screen 11 and the second filter membrane 12 in the second side of block water plate 1,, now in the 3rd embodiment there is variation in the stack of laminations of filter element, and it also comprises the second filter screen 11 and the second filter membrane 12.
For with the second embodiment in the second perforation 17 distinguish, represents that with label 17 ' second in the 3rd embodiment bores a hole.For with the second embodiment in the first perforation 5 differentiate, the first perforation that runs through stack of laminations in this embodiment indicates with 5 '.For distinguishing with the second embodiment, each the second perforation 17 ' middle sleeve is denoted as 10 '.
In the filter element of the 3rd embodiment, the first and second filter screens 2,11 and the first and second filter membranes 7,12 all expose from the internal perisporium of the first perforation 5 ', the first filter screen 2 forms the first water transport channel flowing out from the first perforation 5 ' for the water after the first filter membrane 7 filters, and the second filter screen 11 forms the second water transport channel flowing out from the first perforation 5 ' for the water after the second filter membrane 12 filters.
In the filter element of the 3rd embodiment, the first and second filter screens 2,11 from each the second perforation 17 ' part of exposing all and between sleeve 10 ' water-stop be connected, the first and second filter membranes 7,12 from each second bore a hole the 17 ' part of exposing all and between sleeve 10 ' water-stop be connected.Now, the first filter membrane 7, the first and second retaining ring 6,9 and each sleeves 10 ', form together taking the exhalant canal of the first filter membrane 7 as bottom surface and taking each sleeve 10 ' as delivery port.
In the filter element of the 3rd embodiment, be made as respectively the situation of flange for 10 ' two axial ends of each sleeve, an axial end of sleeve 10 ' is configured to be pressed in the first flanging on the first filter membrane 7, and another axial end of sleeve 10 ' is configured to be pressed in the second flanging on the second filter membrane 12.
Similar to the first embodiment, in the 3rd embodiment, the first filter screen and the second filter screen can be both that single layer structure can be also sandwich construction.
