Abstract
The utility model discloses a quick-operating filter for a pollution index tester, which comprises an upper cover, a lower support and a hoop. A liquid inlet and an air release valve are arranged on the upper cover. A liquid outlet is arranged on the lower support. The upper cover and the lower support are fastened together to form an inner chamber. A sealing ring, a filter membrane and a supporting plate are arranged in the inner chamber. The upper cover and the lower support respectively extend outwards to form an edge with an inclined surface. By using the hoop which is provided with an internal annular groove which is matched with the inclined surface of the edge, the upper cover and the lower support are fastened together to form the sealing inner chamber. Since the internal annular groove of the hoop is in sealing fit with the inclined surfaces of the edges of the upper cover and the lower support, the sealing stress is even, the filter is convenient and quick to operate, and the problems that the filter is apt to be damaged because the existing filter of the pollution index tester is frequently used and the filter membrane is unsmooth because the filter is pressed can be solved. Once the hoop is damaged, the entire filter is not required to be replaced but the hoop is only required to be replaced, and thereby the maintenance cost is reduced.
Description
Technical field
The utility model relates to pollution index tester technical field, is specifically related to a kind of pollution index tester with the fast-open type filtrator.
Background technology
Pollution index (SDI) value is one of effective ways that characterize in colloid and granule content in the pretreated water outlet, be the main the means whether water outlet of check disposal system reaches the feed water by reverse osmosis requirement, the size of SDI numerical value is most important to the operation life of counter-infiltration system.Pollution index tester commonly used at present is mainly duct type pollution index tester, mainly is made up of pipe adapter, valve, voltage stabilizer, tensimeter and filtrator and connecting tube thereof.
China utility model patent ZL01264641.5 discloses a kind of duct type pollution index tester, its filtrator is made up of loam cake, subiculum lid and attaching nut thereof, interlaced fastening and formation chamber between the holder lid, filter membrane, porous supporting plate and sealed picture are set in the chamber, filter membrane is clamped between the supporting plate, and upper and lower holder lid connects the pressing sealing by three groups of bolts.This type of screw thread screws the pollution index tester that tightens up and has following defective: 1. because the high and each test of the frequency of utilization of tester all needs the test diaphragm that more renews, the connection of thread of filtrator is not long serviceable life, and again because whole filtrator is an integrated device, so can't change the connection of thread of damage separately, will cause whole filtrator all can not continue to use; 2. because the filtrator that is threaded needs manual one by one tighting a bolt, easy unbalance stress when therefore manually screwing bolt causes the filter membrane out-of-flatness in the filtrator, influences filter effect.
Summary of the invention
The utility model provides a kind of fast-open type filtrator that is used to the pollution index tester, use, maintenance is all very convenient, solved the prior art middle filtrator owing to frequently use the fragile and filtrator pressing of the filtrator that brings to cause the irregular problem of filter membrane.
A kind of fast-open type filtrator that is used for the pollution index tester comprises loam cake, subiculum and clip, on cover and be provided with inlet, subiculum is provided with liquid outlet; Described loam cake and the subiculum formation inner chamber that is interlocked is provided with sealed picture, filter membrane and back up pad in the inner chamber.
Described loam cake and subiculum stretch out respectively and form the edge on band inclined-plane, by the clip that is provided with the inner groove that matches with this inclined-plane, edge loam cake and subiculum are fastened the formation closed cavity.
Described clip comprises two lobes or the above cutting ferrule of two lobes, and adjacent cutting ferrule is mutually hinged, and lock with bolt the opening and closing place of clip.
Cover on described and be provided with air release, reduce and filter the bubble that produces, improve filter velocity.
The utility model utilizes the fastening filtrator of clamp connection mode, seal stressed even, simple operation, and solved existing pollution index tester filtrator because the filtrator that frequent use brings damages easily and the filtrator pressing causes the irregular problem of filter membrane.In case clip is damaged, only need worse single clip and need not to change filtrator integral body, reduced maintenance cost; Simultaneously, filter membrane is clamped between loam cake and the subiculum and by sealed picture and effectively seals, and makes filter membrane smooth, has improved filter effect.

Fig. 2 is the disassembly and assembly structure synoptic diagram of the utility model fast-open type filtrator.
Fig. 3 is the perspective view of the clip in the utility model fast-open type filtrator.
Embodiment
As shown in Figure 1, a kind of fast-open type filtrator that is used for the pollution index tester, comprise loam cake 1, subiculum 6 and clip 7, loam cake 1 is connected fastening with subiculum 6 by clip 7 and forms inner chamber, be provided with sealed picture 5, filter membrane 2 and back up pad 3 in the inner chamber, loam cake 1 is provided with inlet 8 and the air release 4 that is communicated with inner chamber, and subiculum 6 is provided with the liquid outlet 9 that is communicated with inner chamber.
Shown in Fig. 2,3, loam cake 1 and subiculum 6 stretch out respectively and form the edge on band inclined-plane, are provided with the inner groove 10 that matches with this edge shape in the clip 7, during installation, edge and this inner groove on loam cake 1 and the subiculum 6 are sealed and matched, and the opening and closing place of clip 7 are locked with bolt 11 again.
According to actual needs, clip 9 can be the constructional device that comprises two lobe cutting ferrules, and two lobe cutting ferrules are hinged, and lock with bolt the opening and closing place of clip.When the diameter of filtrator is big, can adopt the structure of the above cutting ferrule of two lobes.
During use, earlier back up pad 3 is placed in the inner chamber place of subiculum 6, filter membrane 2 places on the back up pad 3, placing sealed picture 5 on the filter membrane 2, covers loam cake 1 more then; At last buckle clip 7 in the edge of loam cake 1 and subiculum 6, make the inner groove 10 of clip 7 cooperate respectively with the inclined-plane at two edges, and with the opening and closing place locking of bolt with two lobe cutting ferrules, when tighting a bolt, because the mating reaction on inclined-plane makes loam cake 1 and subiculum 6 evenly seal and fastens.
During maintenance, the bolt of only need outwarding winding unloads lower catch hoop 7, the clip 7 that damages is changed get final product, and former filtrator still can normally use unaffected.
