Abstract
The utility model provides a compound filter screen for declining filter, including first stainless steel filter screen and second stainless steel filter screen, first stainless steel filter screen with second stainless steel filter screen is mutually range upon range of and welded fastening, the mesh diameter of first stainless steel filter screen is 10-100 mu m, the mesh diameter of second stainless steel filter screen is 0.8-1.5 mm, this kind of a compound filter screen for declining filter has disperseed surge pressure when being washed, make filter screen by abundant protection, the filter effect also obtains to improve, compare with the filter screen of the same precision of tradition, rigidity and intensity greatly increased, and the service life is more than 20 years, under the gravity condition of flowing automatically, clear water filter speed reaches 400mhm2, under 5-6bar water pressure, the back flush can be rinsed well completely.
Description
Technical field
The utility model relates to sewage water filtration technical field, particularly relates to a kind of composite screen for micro-filter.
Background technology
A lot of superfine suspended particle is contained in municipal wastewater and trade effluent, sewage is purified and first will filter out these superfine suspended particles, the sewage disposal technology that a kind of filter efficiency is higher is realized by the micro-filter of rotary drum, the micro-filter of this rotary drum sewage is passed into the rotatable filter cylinder being provided with filter net sheet clear water and suspended particle to be separated, filter cylinder comprises filter net sheet, in prior art, this filter net sheet is single layer structure, rigidity is poor, service life is generally no more than 10 years, surge resistance for water is lower, easily cause damage, and filter effect is also not satisfactory.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the technical problem that in prior art, filter net sheet exists, the utility model provides a kind of composite screen for micro-filter and solves the problems referred to above.
The utility model solves the technical scheme that its technical problem adopts: a kind of composite screen for micro-filter, comprise the first stainless steel filtering net and the second stainless steel filtering net, described first stainless steel filtering net is mutually stacked and be welded and fixed with described second stainless steel filtering net, the mesh diameter of described first stainless steel filtering net is 10 ~ 100 μm, and the mesh diameter of described second stainless steel filtering net is 0.8 ~ 1.5 ㎜.
As preferably, described first stainless steel filtering net and the second stainless steel filtering net are mesh grid.
As preferably, the mesh diameter of described first stainless steel filtering net is 20 ~ 60 μm, and the mesh diameter of described second stainless steel filtering net is 1 ~ 1.3 ㎜.
The beneficial effects of the utility model are; this composite screen for micro-filter has disperseed surge when being rinsed; filter net sheet is still adequately protected, and filter effect also obtains raising, compared with the filter screen of traditional same precision; rigidity and intensity increase greatly; service life, under flow by gravity condition, the clear water rate of filtration reached 400m/hm2 more than 20 years; under 5 ~ 6bar hydraulic pressure, backwash can be rinsed well completely.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the optimum embodiment of the composite screen for micro-filter of the present utility model.
1, first stainless steel filtering net in figure, the 2, second stainless steel filtering net.
