The stainless steel filter module 1000 for cleaning polluted water according to the present invention is a stainless steel filter module 1000 for polluting water containing a laminate in which a plurality of filter screens 100 and one or more networked spacers 200 are alternately stacked. A sealing part (300) wrapped around the rim of the laminated body and formed so as to prevent the contaminated water from leaking outside the rim of the laminated body; And a discharge part formed on one side of the sealing part 300 for discharging polluted water and discharging the polluted water. The filtering net 100 is made of stainless steel.

2 and 4, the contaminated water flows into the surface of the filter network 100 and the network spacer 200, and the polluted water passed through the filter network 100 and the network spacer 200 The filtered purified water is discharged through one side of the rim of the laminated body in which the filter net 100 and the network spacer 200 are laminated, that is, the discharge portion formed on one surface of the sealing portion 300.

The contaminated water flows into the surface of the filter net 100 and the network spacer 200. More specifically, the contaminated water flows in the plane direction of the filter net 100 and the network spacer 200, It means direction to look at.

Therefore, the contaminated water can be purified by the simple means that the stainless steel filter module 1000 for dirty water purification according to the present invention is immersed in the contaminated water such as the inside of the contaminated water tank 2000.

5 to 7, the hole is connected to the spacing space formed between the screen 100 and the screen spacers 200. In addition, as shown in FIGS. The size and the size of the holes are not limited because they can be appropriately adjusted according to the processing scale.

The filter module 1000 according to the present invention having such a structure is provided with a simple means for immersing the contaminated water in a space in which the contaminated water is received, for example, a contaminated water receiving tank 2000, Not only has excellent filtration efficiency, but also has a semi-permanent lifetime and can be used for a long time.

As described above, the contaminated water located on the outside of the laminated body flows through one side of the filter net 100 of the laminate, and the filtered purified water is discharged through the discharge portion formed on the side surface of the laminated body. At this time, the flow of the fluid including the polluted water may be induced through a pump or the like. Specifically, a pump may be provided at the rear end of the discharge portion so that the flow of the fluid may be performed through the reduced pressure filtration.

The size, size, shape, etc. of the filter net 100 and the network spacer 200 are not limited because they can be appropriately adjusted depending on the size of the process and the type of polluted water.

Specifically, in describing the 'filter net' in the present specification, the surface may be a plate-like sheet having a plurality of micropores formed as a network structure and having a plurality of micropores formed on its surface. In this case, the plate-like sheet may have various shapes such as a bent shape, and therefore it should not be interpreted as a flat plate. The shape of the sheet may be a form in which a plurality of sheets can be disposed apart from each other. Specifically, the filter net 100 may be a microporous membrane made of stainless steel. The average size of the fine pores is not particularly limited as it can be appropriately adjusted according to the size of contaminants such as suspended solids contained in the purified water. For example, the average size of the micro pores may be in the range of 5 to 500 탆.

Further, the network spacer 200 may have a plurality of through holes as a network structure, and may mean a plate-like sheet having a plurality of through holes formed in its surfaces. At this time, the plate-like sheet may have various shapes such as a bent shape, and therefore it should not be interpreted as a flat plate, and the shape of the sheet may be a form in which a plurality of sheets can be disposed apart from each other. The material of the network spacer 200 is not particularly limited, and may be various materials such as metals, ceramics, glass, polymers, and the like. The mesh spacer 200 may be fabricated by woven fabrics such as fibers, or may be fabricated by physically creating through holes in a plate-shaped sheet. The average size of the through holes may be larger than the average size of the micro pores of the filter net 100 and may be such that the network spacers 200 are positioned between the filter net 100 and have a durability sufficient to secure a space . As a specific example, the average size of the through holes may be not less than a millimeter unit, specifically, 1 mm to 3 cm, but is not limited as it can be appropriately adjusted according to the processing scale and environmental conditions.

As shown in FIGS. 3 and 4, the sealing portion 300 is formed by sealing the edge, that is, the side surface of the laminated body in which the filter net 100 and the networked spacers 200 are disposed to be spaced from each other, It is sufficient that the fluid does not leak through the outside of the rim of the sieve. At this time, the sealing portion 300 may be manufactured in various forms, for example, by applying a polymer adhesive having water-tightness characteristics, or may be formed as a case of a body made integrally as a water-tight material, Each part may have an assembled form. In terms of ease of manufacture, the sealing portion 300 may be formed by applying a polymer adhesive. However, it should be understood that the present invention is not limited thereto.

The stacked body may further include an air injecting portion formed on one side of the sealing portion 300 and through which the air for backwashing the filtering net 100 flows. In order to use the filter module 1000 with a high initial filtration efficiency, it is necessary to solve the problem of lowering the filtration efficiency, for example, the problem that the suspended substances in the contaminated water adhere to the filter net 100. Accordingly, it is preferable that the laminate further includes an air injection unit into which air flows. The air injecting portion may be formed on any surface of the sealing portion 300 and may be formed on the other surface of the sealing portion 300 where the discharging portion is formed as shown in FIG. However, it should be understood that the present invention is not limited thereto.

5 to 10, the mesh spacer 200 may have a structure in which a plurality of protrusions 210 form a waveform, wherein the protrusions 210 are protrusions And an outer end of the formed outer end is in contact with one surface of the filter net 100. If this is the case, a spacing space that does not include the network spacer 200 is further formed among the spacing spaces formed between the filter banks 100, so that a more efficient space can be secured. That is, a first spacing space by the through hole of the network spacer 200; And the second spacing space that does not include the network spacer 200 are formed, the flow of the contaminated water can be smoothly performed, and the flow rate reduction due to the resistance of the network spacer 200 can be minimized.

In a preferred embodiment, as shown in the right drawing of Figs. 6, 7, and 9 and the right drawing of Fig. 10, the protruding portion 210 includes a protruding portion 213 having a net- And a second protrusion 214 having a plate-like surface that can not pass through. Also, the network spacer 200 may have a structure in which the first protrusion 213 and the second protrusion 214 alternate and form a waveform. 7, a vortex is formed as the path of the contaminated water flowing in the laminate is reversed, and the adhering substance adheres to the filter net 100, flocculates and solidifies due to such turbulence Can be minimized. Specifically, a first path (C1) through which the contaminated water passes through the surface in one surface direction of the filtering net (100); And a second path (C2) in which the contaminated water passes through the surface in the other surface direction of the filter net 100, may be formed in the laminate. As shown in FIGS. 9 and 10, since the mesh spacer 200 has a corrugated structure having zigzag shape at a side end, the first path C1 is inclined obliquely with respect to one surface direction of the screen 100 And the second path C2 may be a path that passes through the surface in an oblique direction with respect to the other surface direction of the screen 100. [ Therefore, turbulence formation including eddy currents is smoothly effected while minimizing sheet resistance against fluid flow.

In order to improve the smooth effect of formation of turbulence including vortex while minimizing the sheet resistance against the fluid flow, as shown in FIG. 11, the network spacer 200 is disposed between the filter net 100 The first projecting portion 213 of the first network spacer and the second projecting portion 214 of the second network spacer are preferably opposed to each other when the first network spacer and the second network spacer include neighboring first network spacers and second network spacers can do. In addition, when the ends of the protrusions of the mesh-like spacers 200 adjacent to the one side and the other side of the filter net 100 are staggered rather than facing each other, the formation of turbulence including the vortex while minimizing the sheet resistance against the fluid flow This has a more smooth effect.

8 and 9, the outer ends of the protrusions may have a planar cross-section, and the ends of the protrusions may have a flat cross-section, It is possible to make surface contact with one side. If this is satisfied, even if the laminate body exerts a large force from the outside to the inside due to the stronger decompression, the breakage of the filter net 100 due to the protrusion of the network spacer 200 can be minimized. 8, when the end of the protrusion of the network spacer 200 is sharp, it may cause breakage of the filter net 100. However, as shown in the center and right side views of FIG. 8, The damage of the filter net 100 can be minimized.

8, the protruding portion is protruded to the inside of the second protruding portion 214, and is formed to be spaced apart from a surface of the filtering net 100 that faces the inner surface of the protruding portion. And vortex-forming protrusions 215 that are formed on the surface of the vortex. If this is satisfied, vortices can be given or vortexes can be formed to be larger, and the problem that the adhering substance adheres to the filter net 100, cohesion and solidifies due to the turbulence can be further minimized.

The present invention can provide a filter device including a polluted water receiving tank 2000 in which the filter module 1000 is received. 2, the filter device may further include a polluted water inflow part 400 connected to the inside of the polluted water receiving tank 2000. In some cases, the polluted water receiving tank 2000 And a polluted water outlet 700 connected to the inside of the water outlet 700.

In the example of the present invention, the polluted water receiving tank 2000 includes an air injection hole for allowing a pipe connected to the air injection portion of the filter module 1000 to flow out of the contaminated water receiving tank 2000 . The polluted water receiving tank 2000 may further include a polluted water discharge hole for allowing a pipe connected to the discharge portion of the filter module 1000 to flow out of the polluted water receiving tank 2000.

The contaminated water discharged from the contaminated water outlet 700 may be circulated through the contaminated water outlet 700 and the contaminated water inlet 400 to be recirculated to the contaminated water inlet 400, Can be connected to each other. Therefore, even if a device including a small-sized filter module 1000 is used, a large amount of contaminated water can be effectively treated.
