Description

[Technical Field]

[0001] The present invention relates to a pollutant filtration device, and more particularly to a pollutant filtration device that can cut off rainfall runoff pollutants that penetrate a filter installed in a stormwater drain and protrude into the filter body, thereby enabling smooth filter replacement. [Background technology]

[0002] Generally, pollutants are divided into point sources, which have a clear discharge point, and non-point sources, which have an unclear discharge point. Point sources can be discharged in a more or less purified state by installing separate purification equipment or wastewater treatment facilities at the discharge point.

[0003] On the other hand, non-point pollution sources have unknown emission points and remain on the ground surface over a wide area, and can then flow into water systems such as rivers and streams with rainfall, causing water pollution.

[0004] Examples of non-point sources of pollution include agricultural lands, rangelands, urban streets, forested areas, and suburban areas, where potential non-point pollutants are primarily found on or near the soil surface and washed into water systems by stormwater and carried in runoff.

[0005] Non-point pollutants are pollutants that are mainly washed away with surface runoff during initial rainfall, and include traffic pollutants such as dust and garbage in urban areas, fertilizers and pesticides sprayed on agricultural land, soil erosion, livestock runoff, biological debris, and air pollutants that fall to the ground surface.

[0006] In order to prevent water pollution in rivers and streams due to pollutants contained in such initial rainfall, non-point pollutant filtering devices have been provided.

[0007] Referring to FIG. 1, a conventional filtration device 10 comprises a filtration net body 11 having a large outer shape, and a filtration filter 12 inserted into the filtration net body 11 to collect pollutants 1.

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

[0009] However, in the conventional filtration device 10, when a large amount of contaminants 1 accumulates in the filtration filter 12, the contaminants 1 may cause the filtration filter 12 to swell between the lattice mesh of the filtration net body 11, which is a perforated plate strainer, and the filtration filter 12 may protrude 12a between the filtration net body 11.

[0010] Furthermore, if the filter 12 with the protruding 12a between the filter net bodies 11 is left for a long period of time, the filter 12 may break, or the seeds of plants that flowed in along with the pollutants 1 may sprout and their roots may penetrate the filter 12 and attach to the filter net body 11, making it difficult to replace the filter 12.

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

[0014] Another object of the present invention is to provide a pollutant filtration device in which the filter inserted into the filtration body can be tightly attached to the filtration body, thereby ensuring a large space for collecting pollutants.

[0015] It is yet another object of the present invention to provide a contaminant filtering device capable of blocking the inlet of the filter so that contaminants collected in the filter do not escape to the outside.

[0018] The support member may include an upper frame positioned at the opening of the mesh-structure filtering portion and a plurality of side frames coupled to the upper frame at predetermined intervals.

[0019] The support member may further include a lower frame coupled to the side frames and including a cutting member disposed toward the opening of the mesh-structure filtering portion.

[0020] The support member may further include an auxiliary upper frame installed in close contact with the upper frame, a plurality of auxiliary side frames connected to the auxiliary upper frame at predetermined intervals and installed in close contact with the plurality of side frames, and an auxiliary lower frame including an auxiliary cutting member connected to the plurality of auxiliary side frames and installed toward the opening of the mesh-structure filtration portion.

[0021] The support member may further include a foreign object separation prevention member coupled to the upper frame.

[0022] The support member may further include a fixing member extending from the upper frame and connected to the mesh-structure filtering portion.

[0023] In addition, the mesh-structured filtration unit may include a plurality of surfaces on which a mesh is formed, and at least one of the plurality of surfaces on which the mesh is formed may be partially or entirely separated from the adjacent surface. [Effects of the Invention]

[0024] The contaminant filtering device according to the embodiment of the present invention provides the following advantages.

[0025] The present invention has the advantage of being able to cut off rainfall runoff pollutants that have penetrated a filter installed in a rainwater drain outlet and protruded into the filter body, thereby enabling smooth filter replacement.

DETAILED DESCRIPTION OF THE INVENTION

[0030] The present invention can be modified in various ways and can have various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this does not limit the present invention to the specific embodiments, and it should be understood that the present invention includes all modifications, equivalents, or alternatives that fall within the spirit and technical scope of the present invention.

[0031] The terms used in this application are merely used to describe specific embodiments and are not intended to limit the present invention. The singular expressions include the plural expressions unless the context clearly dictates otherwise. It should be understood that in this application, the terms "comprise" or "have" specify the presence of features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, but do not preclude the presence or additional possibility of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0032] Terms such as "first" and "second" may be used to describe various components, but the components should not be limited by the terms. The terms are used only to distinguish one component from another.

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

[0034] Hereinafter, a filtering device for contaminants according to an embodiment of the present invention will be described in detail with reference to FIGS.

[0035] FIG. 2 is a perspective view illustrating a filtering device for pollutants according to a first embodiment of the present invention, and FIG. 3 is an exploded perspective view illustrating a filtering device for pollutants according to the first embodiment of the present invention.

[0036] As shown in FIGS. 1 and 2, a contaminant filtering device 100 according to a first embodiment of the present invention may include a mesh-structure filtering unit 110, a filtration filter 120, and a support member .

[0037] The mesh-structured filter 110 can filter rainwater runoff or running water containing foreign matter. An opening 111 through which the rainwater runoff or foreign matter enters can be formed on the upper surface of the mesh-structured filter 110.

[0038] A filter 120 is inserted into the mesh-structured filtering section 110, and can filter out foreign matter such as pollutants from rainfall runoff or flowing water containing foreign matter that flows into the opening 111.

[0039] The mesh filter 110 may be connected to a collection device (not shown) installed close to the ground. The collection device may collect rainwater runoff or runoff containing foreign matter and collect it in the openings 111 of the mesh filter 110.

[0040] In one embodiment, the mesh filter unit 110 may be connected to the collection device via a weight detection device (not shown). The weight detection device may measure the weight of the contaminants collected in the mesh filter unit 110. When the weight of the contaminants collected in the mesh filter unit 110 exceeds a preset weight, the weight detection device may generate a filter replacement signal and transmit it to a monitoring server (not shown).

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

[0042] 4, the mesh-structured filtering unit 110 may include a plurality of surfaces on which a mesh having a plurality of filtering holes 112 is formed. The surfaces on which the mesh is formed may be side surfaces and a bottom surface.

[0043] Of the plurality of surfaces on which the net is formed, at least one surface may be partially or entirely separated from an adjacent surface, i.e., at least one surface of the plurality of surfaces on which the net is formed may be open in one direction.

[0044] For example, a plurality of sides of the plurality of surfaces on which the net is formed may be rotatably coupled to one bottom surface by a hinge H. Also, a plurality of sides of the plurality of surfaces on which the net is formed may be connected to adjacent surfaces via separate fastening members C1 and C2. Here, the fastening members C1 and C2 may be locking protrusions and locking rings that are easy to operate.

[0045] Filtration filter 120 can be replaced through opening 111 of mesh-structured filtering unit 110, but filtration filter 120 can also be replaced through at least one of the multiple surfaces on which the mesh is formed that is open.

[0046] The filter 120 may be inserted into the mesh-structured filter unit 110. The filter 120 is shaped like a bag and includes fine holes like a nonwoven fabric, and can discharge flowing water from which contaminants have been filtered through the fine holes.

[0047] The filtration filter 120 may be installed between the mesh-structure filtration unit 110 and the support member 130. The filtration filter 120 may be closely attached to the mesh-structure filtration unit 110 by the support member 130.

[0048] That is, after filtration filter 120 is inserted into mesh-structure filtration unit 110, support member 130 is inserted therein, and filter 120 can be tightly attached to mesh-structure filtration unit 110 according to the shape of support member 130.

[0049] The filtering opening 121 of the filtering filter 120 may be fixed to the inside of the support member 130 or may be hung on the outside of the support member 130 and fixed thereto.

[0050] Contaminants may accumulate in the filter 120. Because the filter 120 is made of a material such as nonwoven fabric, it may expand due to the accumulated contaminants and water pressure. In this case, the filter 120 expands and is pushed into the filter holes 112 of the mesh-structure filtration unit 110, causing parts to break. Contaminants may penetrate the broken parts of the filter 120.

[0051] Next, when support member 130 inserted into filtration filter 120 is removed from mesh-structure filtration section 110, contaminants that have penetrated filtration filter 120 can be cut by support member 130.

[0052] This allows filtration filter 120 to be easily separated from mesh-structure filtration portion 110.

[0053] Meanwhile, in the drawings, the filtration filter 120 is illustrated as being formed in an approximately rectangular shape, but this is for the sake of simplicity of explanation, and as explained above, it can be formed in any shape such as a nonwoven fabric.

[0054] The support member 130 may be inserted into the opening 111 of the mesh-structure filtration unit 110 to support the filtration filter 120 so that the filtration filter 120 is in close contact with the inside of the mesh-structure filtration unit 110. Here, the support member 130 may be inserted into the filtration filter 120 inserted into the opening 111 of the mesh-structure filtration unit 110.

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

[0056] The upper frame 131 may be positioned at the opening 111 of the mesh-structure filtration unit 110. The upper frame 131 may have a support opening 1311 formed at a position corresponding to the opening 111 of the mesh-structure filtration unit 110. A plurality of side frames 132 may be coupled to the upper frame 131.

[0057] The side frames 132 may be coupled to the upper frame 131 at a predetermined interval. A plurality of side frames 132 may be formed. The side frames 132 may be formed in a straight or U-shape, and may tightly attach the filtration filter 120 to the mesh-structure filtration unit 110.

[0058] 5, the support member 130 may 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 may be located inside the support member 130.

A plurality of auxiliary side frames 134 may be coupled to the auxiliary upper frame 133.

[0060] The auxiliary side frames 134 may be coupled to the auxiliary upper frame 133 at a predetermined interval and installed to be in close contact with the plurality of side frames 132. A plurality of auxiliary side frames 134 may be configured. The auxiliary side frames 134 may be formed in a straight line shape, a U-shape, or the like.

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

[0062] The auxiliary lower frame 135 may be coupled to the plurality of auxiliary side frames 134. The auxiliary lower frame 135 may include an auxiliary cutting member 1351 disposed toward the opening 111 of the mesh-structure filtering unit 110.

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

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

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

[0066] The foreign matter separation prevention member 136 may be installed in the support opening 1311 of the upper frame 131 of the support member 130. The foreign matter separation prevention member 136 may close a portion of the support opening 1311 to minimize the phenomenon in which contaminants accumulated inside the filtration filter 120 are separated into the support opening 1311.

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

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

[0069] The fixing member 137 may extend from the upper frame 131 and be connected to the mesh-structure filtration unit 110. The fixing member 137 may have a U-shaped cross section and may fit into at least one surface 113 located in the opening 111 of the mesh-structure filtration unit 110.

[0070] The fixing member 137 can prevent the filtration filter 120 and the support member 130 from shaking significantly inside the mesh-structure filtration unit 110. In addition, the fixing member 137 can be fixed to the mesh-structure filtration unit 110 after the filtration opening 121 of the filtration filter 120 is fitted into the fixing member 137.

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

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

[0073] The mesh-structure filtration section 210, filtration filter 220 and support member 230 of this embodiment have the same configuration as the mesh-structure filtration section 110, filtration filter 120 and support member 130 described in the first embodiment, so detailed explanations will be omitted and only the different configurations will be described.

[0075] The lower frame 233 may be coupled to the plurality of side frames 232. The lower frame 233 may include a cutting member 2331 disposed toward the opening 211 of the mesh-structure filtering unit 210.

[0076] The cutting member 2331 is connected to the upper part of the lower frame 233 and is formed sharp like a blade, so that it can cut contaminants that have penetrated the filtration filter 220 .

[0077] In one embodiment, a silicon member (not shown) may be bonded to the inner surface of the cutting member 2331 facing the support opening 2311. The silicon member may prevent the filtration filter 220 from being cut by the cutting member 2331.
