Description

Technical Field

[0001] The present invention relates to a pollutant filtration device, and more particularly, to a device that can cut off pollutant substances in rainfall outflow water that protrude into a filtration main body through a filtration filter installed at a rainwater drainage outlet, and can smoothly replace the filtration filter.

Background Art

[0002] Generally, pollutants are classified into point sources of pollution where the discharge location is clear and non-point sources of pollution where the discharge location is unclear. Point sources of pollution can be discharged in a somewhat purified state because another purification device or wastewater treatment facility is installed at the discharge location.

[0003] On the other hand, non-point sources of pollution have an unclear discharge location, remain on a wide area of the ground surface, and then, together with rainfall, flow into water systems such as rivers and streams, which can cause water pollution.

[0004] Examples of non-point sources of pollution include agricultural land, grazing land, urban streets, mountain forest land, suburban areas, etc. Mainly, potential non-point pollutant substances on the surface of the soil or near the ground surface are washed by rainwater, contained in the outflow water, and flow into the water system.

[0005] Non-point pollutant substances are mainly pollutant substances that flow out together with surface runoff water during the initial rainfall, and mean traffic pollutant substances such as dust and garbage in urban areas, fertilizers and pesticides sprayed on agricultural land, soil leachates, livestock shed effluents, biological residues, air pollutants that have fallen on the ground surface, etc.

[0006] In order to prevent water pollution in rivers, streams, etc. caused by such pollutants contained in the initial rainfall, a non-point pollutant filtration device is provided.

[0007] Referring to FIG. 1, a conventional filtration device 10 includes a filtration net main body 11 that forms a large outer shape, and a filtration filter 12 that is inserted into the filtration net main body 11 and collects pollutants 1.

[0008] The filter mesh body 11 is a perforated plate strainer for maintaining the shape of the filter 12 and suppressing the expansion of the voids in the filter 12.

[0009] However, in the conventional filtration device 10, when a large amount of contaminants 1 are accumulated in the filter 12, the filter 12 may bulge between the grating meshes of the filter mesh body 11, which is a perforated plate strainer, and the filter 12 may protrude 12a between the filter mesh bodies 11.

[0010] Also, when the filter 12 protruding 12a between the filter mesh bodies 11 is left unattended for a long time, the filter 12 may break, or the seeds of plants that have flowed in together with the contaminants 1 may germinate, and the roots may penetrate the filter 12 and adhere to the filter mesh body 11 side, which poses a problem of making it difficult to replace the filter 12.

[0011] Therefore, when separating the filter 12 from the filter mesh body 11 to replace the filter 12, there is a risk that the filter 12 may be easily separated from the filter mesh body 11 due to the filter 12 protruding 12a from the filter mesh body 11 and the contaminants 1, or a problem that the filter 12 may be torn.

[0030] The present invention can be subjected to various transformations and can have various embodiments. Specific embodiments are illustrated in the drawings and will be described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that it includes all transformations, equivalents, or alternatives included in the spirit and technical scope of the present invention. When explaining the present invention, if it is determined that a specific description of related known technologies may obscure the gist of the present invention, the detailed description thereof will be omitted.

[0031] The terms used in this application are merely used to describe specific embodiments and are not intended to limit the present invention. Singular expressions include plural expressions unless the context clearly indicates a different meaning. In this application, terms such as "including" or "having" are used to specify the presence of features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, and it should be understood that they do not pre-exclude the presence or possibility of addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0032] Terms such as first, second, etc. can be used to describe various components, but the components should not be limited by the terms. The terms are only used for the purpose of distinguishing one component from another.

[0033] Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. When explaining with reference to the accompanying drawings, regardless of the reference numerals in the drawings, the same or corresponding components will be given the same reference numerals, and duplicate descriptions thereof will be omitted.

[0034] Hereinafter, a pollutant filtration device according to an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 11.

[0035] FIG. 2 is a perspective view showing a pollutant filtration device according to the first embodiment of the present invention, and FIG. 3 is an exploded perspective view showing the pollutant filtration device according to the first embodiment of the present invention.

[0036] As shown in FIGS. 1 and 2, the pollutant filtration device 100 according to the first embodiment of the present invention can include a network structure filtration unit 110, a filtration filter 120, and a support member 130.

[0037] The network structure filtration unit 110 can filter rainfall runoff water or running water containing foreign substances. An opening 111 through which rainfall runoff water or foreign substances flow in can be formed on the upper surface of the network structure filtration unit 110.

[0038] The filtration filter 120 is inserted into the network structure filtration unit 110, and can filter foreign substances such as pollutants from the rainfall runoff water or running water containing foreign substances flowing into the opening 111.

[0039] The network structure filtration unit 110 can be connected to a collection device (not shown) installed near the ground. The collection device can collect rainfall runoff water or running water containing foreign substances and collect it at the opening 111 of the network structure filtration unit 110.

[0040] In one embodiment, the network structure filtration unit 110 can be connected to the collection device by a weight detection device (not shown). The weight detection device can measure the weight of the pollutants collected in the network structure filtration unit 110. When the weight of the pollutants collected in the network structure filtration unit 110 exceeds a preset weight, the weight detection device can generate a filter replacement signal and transfer it to a monitoring server (not shown).

[0041] Here, the monitoring server can manage the filtration filter 120 installed in the network structure filtration unit 110 according to the filter replacement signal.

[0042] Referring to FIG. 4, the network structure filtering part 110 can include a plurality of surfaces formed by a network including a plurality of filtering holes 112. The plurality of surfaces formed by the network can be side surfaces and a lower surface.

[0043] A part or all of at least one of the plurality of surfaces formed by the network can be separated from the adjacent surfaces. That is, at least one of the plurality of surfaces formed by the network can be open in one direction.

[0044] For example, a plurality of side surfaces among the plurality of surfaces formed by the network can be rotatably coupled to one lower surface by a hinge H. Also, a plurality of side surfaces among the plurality of surfaces formed by the network can be connected to each other via other fastening members C1, C2 adjacent to each other. Here, the fastening members C1, C2 can be locking protrusions and locking rings with simple operations.

[0045] Although the filter 120 can be replaced by the opening 111 of the network structure filtering part 110, the filter 120 can also be replaced by at least one of the opened surfaces among the plurality of surfaces formed by the network.

[0046] The filter 120 can be inserted into the network structure filtering part 110. The filter 120 has a bag-like shape and includes fine holes like non-woven fabric, and can discharge the running water filtered of contaminants through the fine holes.

[0047] The filter 120 can be installed between the network structure filtering part 110 and the support member 130. The filter 120 can be in close contact with the network structure filtering part 110 by the support member 130.

[0048] That is, after the filter 120 is inserted into the network structure filtering part 110, the support member 130 is inserted inside, and can be in close contact with the network structure filtering part 110 according to the shape of the support member 130.

[0049] The filtration opening 121 of the filtration filter 120 may be fixed inside the support member 130, or may be fixed by being applied to the outside of the support member 130.

[0050] Contaminants can accumulate in the filtration filter 120. Since the filtration filter 120 is formed of a material such as a non-woven fabric, it can expand due to the accumulated contaminants and water pressure. In this case, the filtration filter 120 bulges upward, is pushed out into the filtration holes 112 of the net structure filtration part 110, and a part thereof breaks. Contaminants can penetrate through the broken part of the filtration filter 120.

[0051] Next, when the support member 130 inserted into the filtration filter 120 is removed from the net structure filtration part 110, the support member 130 can cut off the contaminants that have penetrated the filtration filter 120.

[0052] Thereby, the filtration filter 120 can be easily separated from the net structure filtration part 110.

[0053] On the other hand, in the drawings, the filtration filter 120 is illustrated as being formed in a substantially rectangular shape, but this is for simple explanation, and as described above, it can be formed in a free shape such as a non-woven fabric.

[0054] The support member 130 can be inserted into the opening 111 of the net structure filtration part 110 so as to support the filtration filter 120 in close contact with the inside of the net structure filtration part 110. Here, the support member 130 can be inserted into the inside of the filtration filter 120 inserted into the opening 111 of the net structure filtration part 110.

[0055] The support member 130 can include an upper frame 131 and side frames 132.

[0056] The upper frame 131 can be positioned at the opening 111 of the mesh structure filter section 110. A support opening 1311 can be formed in the upper frame 131 at a position corresponding to the opening 111 of the mesh structure filter section 110. A plurality of side frames 132 can be coupled to the upper frame 131.

[0057] The side frame 132 can be coupled to the upper frame 131 with a predetermined interval therebetween. The side frame 132 can be composed of a plurality of members. The side frame 132 can be formed in a straight shape, a U-shape, etc., and the filter 120 can be brought into close contact with the mesh structure filter section 110.

[0058] As a first example, referring to FIG. 5, the support member 130 can further include an auxiliary upper frame 133, an auxiliary side frame 134, and an auxiliary lower frame 135. The auxiliary upper frame 133, the auxiliary side frame 134, and the auxiliary lower frame 135 can be positioned inside the support member 130.

[0059] The auxiliary upper frame 133 can be installed so as to be in close contact with the upper frame 131.

The auxiliary side frame 134 can be composed of a plurality of members. The auxiliary side frame 134 can be formed in a straight shape, a U-shape, etc.

[0061] The auxiliary lower frame 135 can be coupled to the auxiliary side frame 134.

[0062] The auxiliary lower frame 135 can be coupled to a plurality of auxiliary side frames 134. The auxiliary lower frame 135 can include an auxiliary cutting member 1351 installed toward the opening 111 of the mesh structure filtering section 110.

[0063] The auxiliary cutting member 1351 is coupled to the upper part of the auxiliary lower frame 135, is sharply formed like a blade, and can cut contaminants that have penetrated the filter 120.

[0064] Here, the filter 120 can be installed between a frame composed of the upper frame 131 and the side frame 132 and a frame composed of the auxiliary upper frame 133, the auxiliary side frame 134, and the auxiliary lower frame 135.

[0065] As a second example, referring to FIG. 6, the support member 130 can further include a foreign object detachment prevention member 136.

[0066] The foreign object detachment prevention member 136 can be installed in the support opening 1311 of the upper frame 131 of the support member 130. The foreign object detachment prevention member 136 can close a part of the support opening 1311 and minimize the phenomenon that contaminants accumulated inside the filter 120 detach from the support opening 1311.

[0067] In one embodiment, the foreign object detachment prevention member 136 is formed in the form of a sliding door and can selectively close or completely close the support opening 1311.

[0068] As a third example, referring to FIG. 7, the support member 130 can further include a fixing member 137.

[0069] The fixing member 137 can extend from the upper frame 131 and be connected to the mesh structure filtering section 110. The fixing member 137 has a U-shaped cross-section and can be fitted to at least one surface 113 located at the opening 111 of the mesh structure filtering section 110.

[0070] The fixing member 137 can prevent the filtering filter 120 and the support member 130 from shaking greatly inside the network structure filtering part 110. Further, after the filtering opening 121 of the filtering filter 120 is fitted to the fixing member 137, it can be fixed to the network structure filtering part 110.

[0071] FIG. 8 is an exploded perspective view showing a contaminant filtering device according to a second embodiment of the present invention.

[0072] As shown in FIG. 8, the contaminant filtering device 200 according to the second embodiment of the present invention can include a network structure filtering part 210, a filtering filter 220, and a support member 230.

[0073] Since the network structure filtering part 210, the filtering filter 220, and the support member 230 according to the present embodiment have the same configurations as the network structure filtering part 110, the filtering filter 120, and the support member 130 described in the first embodiment, detailed descriptions thereof are omitted, and only different configurations will be described.

[0074] The support member 230 can further include a lower frame 233.

[0075] The lower frame 233 can be coupled to a plurality of side frames 232. The lower frame 233 can include a cutting member 2331 installed toward the opening 211 of the network structure filtering part 210.

[0076] The cutting member 2331 is coupled to the upper part of the lower frame 233, is formed sharp like a blade, and can cut contaminants passing through the filtering filter 220.

[0077] In one embodiment, a silicon member (not shown) can be coupled to the inner surface of the cutting member 2331 facing the support opening 2311. The silicon member can prevent the phenomenon that the filtering filter 220 is cut by the cutting member 2331.

[0078] In the first example, referring to FIG. 9, the support member 230 can further include an auxiliary upper frame 234, an auxiliary side frame 235, and an auxiliary lower frame 236. The auxiliary upper frame 234, the auxiliary side frame 235, and the auxiliary lower frame 236 can be inserted into the support member 230 through the lower frame 233 of the support member 230.

[0079] The auxiliary upper frame 234 can be installed so as to be in close contact with the upper frame 231. An auxiliary opening 2341 can be formed in the auxiliary upper frame 234 at a position corresponding to the support opening 2311 of the upper frame 231. A plurality of auxiliary side frames 235 can be coupled to the auxiliary upper frame 234.
