Description

The environmental protection filter structure of recyclable utilization

The utility model relates to a kind of environmental protection filter structure of relevant recyclable utilization, this filtering element (cartridge) mainly is to be run through to connect by aqueduct to go up water-collecting tray, diffusion disc, filter sand, waterstop pad, following water-collecting tray, base, and the inside of the shell of packing in regular turn, and be screwed into one by base and shell, in addition a sheathed turnover water valve at the coaxial intake-outlet place of base; Wherein: enclosure is provided with fixedly circle body and terrace edge, use the location in the time of can keeping supplying the installing of water-collecting tray and diffusion disc, between last water-collecting tray and diffusion disc, fill simultaneously and can eliminate the filter materials such as activated carbon that change renewal, filter sand or other filter material of die cast then are set between diffusion disc and following water-collecting tray, external diameter as special filter material of ceramic die casting etc. is identical, make water by filter sand or other filter material, enter the open-work in the center of circle as the special filter material equal circumference of ceramic die casting, again by the radial dividing plate uniform distribution of diffusion disc to the cross section of each filter material, filter last the concentrating in back and discharge by aqueduct.

Please consult shown in Figure 1: it is the section combination schematic diagram of traditional filtering element (cartridge).Traditional filter structure comprises: a shell 1 and lid 2 of being made by plastic cement material, and a cartridge filter 3 of being made by ABS (plastic material); Wherein: be provided with an axle bed 4 at shell 1 bottom centre place, use axle and establish fixedly cartridge filter 3, reserve the suitable flowing space 5 between right this shell 1 and the cartridge filter 3, filter materials 6 such as activated carbon are filled in cartridge filter 3 inside simultaneously, and wear at the bottom and the top of cartridge filter 3, water outlet open-

work

7,8, allow water import from the water inlet 9 of lid 2, water inlet open-work 7 via cartridge filter 3 bottoms enters in the filter materials 6 such as activated carbon again, filter out impurities, suspension, after the peculiar smell, concentrate from the water outlet open-work 8 at cartridge filter 3 tops at last, derive by the delivery port 10 of lid 2 again, the shell 1 of tradition filtering element (cartridge) is in the utilization with lid 2,

external screw thread

11,12 are screwed into one mutually, simultaneously a sheathed sealing packing ring 13 between shell 1 and lid 2; But still there are following several the shortcomings that wait to overcome in above-mentioned traditional filter structure in actual manufacturing, assembling, application:

1. traditional filtering element (cartridge) is in order to allow water can enter from the water inlet open-work of cartridge filter bottom the filter material such as activated carbon, shell that diameter is bigger of essential making in addition, make cartridge filter can be contained in enclosure, and and cartridge filter between keep the flowing space of suitable water, on making, must make shell and cartridge filter respectively, increase material and raise the cost.

2. the flowing space of traditional filtering element (cartridge) between shell and cartridge filter, only supply water and flow into the open-work that enters of cartridge filter bottom from top to bottom, on space utilization and spatial design, though make that traditional filtering element (cartridge) volume is big but fail to fill a part utilization overall space, make filter material loading capacity deficiencies such as activated carbon, so filter effect is not good.

3. the filter materials such as activated carbon of traditional filtering element (cartridge) are to fill to be closed in the cartridge filter, are a disposal type filtering element (cartridge), and after filter materials such as activated carbon lost efficacy, cartridge filter can't recycling, increase the consumer when changing filtering element (cartridge) cost and the pollution that causes environment.

4. be inner, external screw thread locking fully between the shell of traditional filtering element (cartridge) and the lid, though between shell and lid, be provided with the sealing packing ring, if but lock is tight inadequately, still the situation that can leak, be integral so when mounted must be very at full tilt shell and lid be locked tightly, make and when changing cartridge filter, must arduously shell and lid be outwarded winding that some trouble and inconvenience seem.

The filter structure that another is conventional, please consult shown in Figure 2: it is the section combination schematic diagram of conventional filtering element (cartridge).Conventional filter structure is that the shell 1 with traditional filtering element (cartridge) is combined into one with cartridge filter 3, finish the structure of the cartridge filter 3 of forgoing, directly filter materials such as activated carbon 6 are filled in shell 1 inside, its structure mainly is to be provided with a fixedly axle bed 15 in shell 14, so fixedly axle bed 15 centers are the axis hole post 16 of a hollow, and in the densely covered a plurality of open-works 17 of axis hole post 16 surface hollow-outs one-tenth, and on axis hole post 16, following one-body molded two fixed disks 18 that are provided with, 19, can be last, following two fixed disks 18, filter material 20 such as die cast one activated carbon between 19, allow simultaneously and keep the suitable hydrospace 21 of crossing between the inwall of filter material 20 such as activated carbon and shell 14, utilize sheathed sealing and fixing one lid 22 of solid in addition at shell 14 tops, and these lid 22 centers are provided with an Inlet and outlet water jack-post 23, axially extend a delivery port 24 to be drilled with two water inlets 25 with radially locating to run through respectively at Inlet and outlet water jack-post 23 again, allow water enter crossing the hydrospace 21 of shell 14 inwalls from water inlet 25, infiltrate filter materials 20 such as activated carbon simultaneously from top to bottom from circumference, impurity in the filtering water, suspension, peculiar smell, after the toxin, infiltrate axis hole post 16 centers by a plurality of densely covered open-works 17 again, clean water is promptly discharged from delivery port 24 from lower to upper after filtering at last; But the filter structure of above-mentioned routine still exists following several to wait to overcome the deficiency in actual manufacturing, assembling, application:

1. routine is a disposal type filtering element (cartridge), its shell and lid have bondd fully with solid and have been fixed into one, at all can't dismounting and change the filter materials such as activated carbon of the inside, after the filtering element (cartridge) shell of plasthetics and lid can't being reclaimed, again load new filter materials such as activated carbon and utilize again, will cause the substantial pollution of environment after abandoning.

2. conventional filtering element (cartridge) is the hydrospace of crossing that water is imported between the filter materials such as shell and activated carbon, allow water by in the filter materials such as cross section infiltration activated carbon, but this kind filter run is too short, and filter effect is not good.

3. as shown in Figure 2, conventional filtering element (cartridge) water is imported between the filter materials such as shell and activated carbon cross the hydrospace after, it is inhomogeneous that hydraulic pressure is born in the stream course change of A shown in the figure, B, C, D, each section of E.

The purpose of this utility model be to propose a kind of by shell, go up water-collecting tray, aqueduct, diffusion disc, filter sand and filter material, the environmental protection filter structure of the recyclable utilization formed of water-collecting tray, waterstop pad, base and turnover water valve down, its structure is easy, the replacing filter material is simple, and volume is little and good filtration effect, thereby has solved the existing in prior technology problem.

The technical scheme that the utility model adopted is:

This filtering element (cartridge) by shell, go up water-collecting tray, aqueduct, diffusion disc, filter sand or other filter material (as the special filter material of ceramic die casting etc.), water-collecting tray, waterstop pad, base, turnover water valve are formed down; Wherein:
