Abstract
The utility model provides a filter mesh for a micro filter. The filter mesh comprises a first stainless steel welded net, a first filter net, a second filter net and a second stainless steel welded net of which the radians are the same and the arc lengths increase in sequence, wherein the first stainless steel welded net, the first filter net, the second filter net and the second stainless steel welded net are arranged in sequence, and the edges are fixed by welding through stainless steel covering edges; the mesh diameter of the first filter net is 10-50 millimeters; the mesh diameter of the second filter net is 10-50 microns. The filter mesh for the micro filter is provided with double layers of filter nets and double layers of stainless steel welded nets, thereby dispersing impact pressure during flushing, fully protecting the filter mesh and enhancing the filtering effect; the filter nets and the stainless steel welded nets are fixed by welding through the covering edges, thereby enhancing the rigidity of the entire filter mesh, preventing the filter mesh from being damaged, prolonging the service life, and reducing the maintenance cost.
Description
Technical field
The utility model relates to sewage water filtration technical field, relates in particular to a kind of filter net sheet for micro-filter.
Background technology
In municipal wastewater and trade effluent, contain a lot of superfine suspended particles, 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 to realize by the micro-filter of rotary drum, the micro-filter of this rotary drum is sewage to be passed into the rotatable filter cylinder that filter net sheet is installed clear water and suspended particle are separated, filter cylinder comprises filter net sheet, in prior art, this filter net sheet is single layer structure, rigidity is poor, 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 filter net sheet in prior art, have the problem that poor rigidity, impact resistance are not good and filter effect is undesirable, the utility model provides a kind of filter net sheet for micro-filter to have sandwich construction and solved the problems referred to above.
The utility model solves the technical scheme that its technical problem adopts: a kind of filter net sheet for micro-filter, comprise radian is identical, arc length increases progressively successively the first stainless steel welded mesh, the first screen pack, the second screen pack and the second stainless steel welded mesh, described the first stainless steel welded mesh, the first screen pack, the second screen pack and the second stainless steel welded mesh are arranged in order and edge is welded and fixed by stainless steel bound edge, the mesh diameter of described the first screen pack is 10 ~ 50 millimeters, and the mesh diameter of described the second screen pack is 10 ~ 50 microns.
As preferably, the mesh diameter of described the first screen pack is 15 millimeters, and the mesh diameter of described the second screen pack is 15 microns.
Concrete, described the first stainless steel welded mesh, the first screen pack, the second screen pack and the second stainless steel welded mesh have the parallel relative arc minor face and two long limits of parallel relative linear that length is identical that two strips are identical
The beneficial effects of the utility model are, this filter net sheet for micro-filter has double-layer filtering net and double-layer stainless steel welded mesh, has disperseed surge when being rinsed, and filter net sheet is adequately protected, and filter effect also obtains raising; Screen pack and stainless steel welded mesh are welded and fixed by bound edge, and the rigidity of whole filter net sheet is enhanced, and are difficult for damagedly, have improved service life, reduce maintenance cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is that the utility model is for the structural representation of the optimum embodiment of the filter net sheet of micro-filter.
Fig. 2 is the A-A cutaway view of Fig. 1.
The 1, first stainless steel welded mesh in figure, the 2, first screen pack, the 3, second screen pack, the 4, second stainless steel welded mesh, 5, bound edge.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1 and 2, the utility model provides a kind of filter net sheet for micro-filter, comprise that radian is identical, the first stainless steel welded mesh 1 that arc length increases progressively successively, the first screen pack 2, the second screen pack 3 and the second stainless steel welded mesh 4, the first stainless steel welded mesh 1, the first screen pack 2, the second screen pack 3 has with the second stainless steel welded mesh 4 the parallel relative arc minor face and two long limits of parallel relative linear that length is identical that two strips are identical, the first stainless steel welded mesh 1, the first screen pack 2, the second screen pack 3 and the second stainless steel welded mesh 4 be arranged in order and, by stainless steel bound edge 5, the long side weld of their arc minor face and linear is connect and is fixed together, the mesh diameter of the first screen pack 2 is 15 millimeters, the mesh diameter of the second screen pack 3 is 15 microns.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
