Description

Technology Field

[0001] The present invention relates to an inclined plate sedimentation device, and more specifically, to an upward-flow modular inclined plate sedimentation device. Background Technology

[0002] In general, physical, chemical, and biological treatment methods are used for the purification of wastewater. Among these, physical treatment uses mechanical devices such as sedimentation tanks and screens to separate solid particle sludge contained in wastewater from water. In the case of sedimentation tanks, sludge particles in the incoming raw water are settled by gravity and the supernatant is discharged. To expand the sedimentation area and increase the settling speed of the sludge, an inclined plate type with an inclined plate inserted inside is mainly used.

[0003] Conventional inclined plate sedimentation devices are equipped with a predetermined sedimentation space and are installed with a structure in which multiple inclined plates are spaced apart from each other and arranged at an angle within the sedimentation space. In the case of modular inclined plate sedimentation devices, the products are assembled into modules during the manufacturing process and then connected and installed on-site. Inclined plate sedimentation devices can generally be classified into upward-flow inclined plates and horizontal-flow inclined plates depending on the water flow. The upward-flow inclined plate has an inclined plate installed at the bottom to induce particle sedimentation and a trough installed at the top to collect treated water processed through the inclined plate; in this structure, floc is settled and removed from the rising fluid onto the inclined plate, and the separated supernatant is discharged through the upper trough. The horizontal-flow inclined plate is installed vertically in the sedimentation tank, and raw water flows along the side of the inclined plate while sludge settles downwards and the raw water flows horizontally; in this structure, a trough for collecting treated water is installed separately at the rear end.

[0004] Although sedimentation efficiency varies depending on the application, upward-flow inclined plates are widely used to prevent accumulation of sludge flocs in the inclined plates when treating raw water containing high turbidity.

[0005] Regarding the material of the inclined plate, steel structures such as STS (stainless steel) have high strength and small deformation, making installation convenient, but sludge tends to accumulate and adhere to the surface of the inclined plate, so non-metallic materials such as ABS, PVC, and FRP are generally used.

[0006] These inclined plates increase the settling velocity of flocs in the sedimentation tank, allowing them to settle quickly. Consequently, the retention time of the sedimentation tank is shortened, which allows the sedimentation tank structure to be designed to be smaller, and the capacity can be increased within the same structure, thereby reducing the installation cost of the structure.

[0007] Meanwhile, the modular inclined plate sedimentation device having a hybrid structure is an upward-flow inclined plate sedimentation device in which curved inclined pipes are attached one by one in a tube shape to create small-unit modules of a certain size, and these small-unit modules are assembled within a secondary module of a certain size with a steel structure to create an inclined plate module that can be transported and installed. A trough is installed at the top to collect the treated water processed through the inclined plate, and the structure is such that flocs are settled and removed from the rising fluid onto the inclined plate, and the separated supernatant is discharged through the upper trough. Unlike general upward-flow inclined plates which have a thickness of 2 to 3 mm, this tubular inclined plate has a thickness of about 1 mm or less to reduce weight, and the gap between the inclined plates is narrowed to allow for a large projected area, making it effective for treating raw water sludge with slow sedimentation rates, such as in water purification and tertiary sewage treatment.

[0008] However, in a modular inclined plate sedimentation device having such a hybrid structure, if the weight of the small-unit primary module increases significantly due to sludge adhesion during operation, a secondary module structure capable of sufficiently supporting it is required. Furthermore, if the shape of the frame itself forming the secondary module is inefficient, sludge adheres to the module, which reduces the sedimentation efficiency of the floc. Additionally, in the case of small-unit inclined plate modules, the projected area can be increased by narrowing the gap between the inclined plates; however, in this case, depending on the attachment method of the inclined plates, sludge accumulation may worsen due to issues such as detachment during use, which may actually cause problems. The problem to be solved

[0009] The present invention aims to provide an upward-flow modular inclined plate sedimentation device comprising a primary inclined plate module forming a certain pattern in the form of an inclined pipe and a secondary steel module in the form of a frame that allows the primary inclined plate module to be installed inside, and an upward-flow modular inclined plate sedimentation device having a hybrid structure comprising a secondary steel module capable of sufficiently supporting the primary inclined plate module assembled within the secondary steel module.

[0010] In addition, regarding an upward-flow modular inclined plate sedimentation device comprising a primary inclined plate module forming a certain pattern in the form of an inclined pipe and a secondary steel module in the form of a frame that allows the primary inclined plate module to be installed inside, the present invention aims to provide an upward-flow modular inclined plate sedimentation device having a hybrid structure that can solve problems such as the gap between the inclined plates of the primary inclined plate module becoming detached due to damage to the assembled stapler part during use, causing the floc to accumulate during sedimentation, or the sedimentation efficiency decreasing as the spacing distance between the inclined plates increases in the space created by the detachment.

[0011] In addition, we aim to provide an upward-flow modular inclined plate sedimentation device having a hybrid structure as a safe structure by implementing a support structure using less material that can solve the problem of sagging when the weight of the primary forced module increases significantly due to sludge adhesion during operation, thereby reducing the sludge adhesion problem and providing economic benefits, and by changing the manufacturing process differently from existing methods. means of solving the problem

[0012] To solve the above problem, the present invention provides an upward-flow modular inclined plate sedimentation device installed inside a sedimentation tank, comprising: a primary inclined plate module in which the vertical surfaces of inclined pipes made of a non-metallic material tilted at a certain angle are attached to each other to form a certain pattern; and a secondary steel module in the form of a frame that allows the primary inclined plate module to be installed inside. The secondary steel module comprises: a horizontal support member provided with square pipes around the upper and lower perimeters, on which the primary inclined plate module is supported at the bottom; a vertical reinforcing member connecting the upper and lower horizontal support members at four corners and having an L-shaped cross section; a lower support member connected by square pipes between the longitudinal directions of the lower horizontal support member to support the primary inclined plate module; and a buoyancy prevention member in the form of a vertical bar connected in the longitudinal directions of the upper horizontal support member to prevent the primary inclined plate module from rising. The present invention provides an upward-flow modular inclined plate sedimentation device having a hybrid structure comprising: a triangular tension structure member connected in the form of a vertical bar and a diagonal bar between the upper and lower horizontal support members in the longitudinal direction to reinforce the load-bearing capacity of the secondary steel module.

[0013] In addition, the present invention provides an upward-flow modular inclined plate sedimentation device having a hive structure characterized in that the inclined pipe has a cross-section in the shape of a trapezoid or a hexagon, the vertical surfaces are attached to each other using an adhesive, and the inclined surfaces are not attached to each other, allowing floc to detach from the inclined plate through fine shaking.

[0014] In addition, the above horizontal support member, the above vertical reinforcement member, and the above lower support member are fixed by welding, and the above buoyancy prevention member and the above triangular tension structure member are fixed by rivets after the first inclined plate module assembly, thereby providing an upward-flow modular inclined plate sedimentation device having a hybrid structure.

[0015] In addition, the assembly between the second forced modules is characterized by being achieved by fixing the upper horizontal support member through a bolt, nut, and wedge dog while the wedge dog structure, which is equipped with a bolt hole formed on the inner side of the upper horizontal support member, surrounds the upper horizontal support member. This provides an upward-flow modular inclined plate sedimentation device having a hybrid structure.

[0016] Additionally, the present invention provides an upward-flow modular inclined plate sedimentation device having a hybrid structure, characterized in that a bent flow guide plate is installed on the upper part of the first inclined plate module and connected to guide plates on both sides, the guide plates are positioned on the upper horizontal support member, and the assembly between the second inclined plates is achieved by fixing the guide plates through using bolts, nuts, and wedge dogs while a wedge dog structure, equipped with bolt holes formed on the inner surface of the upper horizontal support member and the guide, surrounds the upper horizontal support member and the guide plates.

[0017] In addition, an upward-flow modular inclined plate sedimentation device having a hive structure is provided, characterized by the installation of a trough on the upper part of the primary inclined plate module to allow treated water processed through the inclined plate to overflow through a plurality of orifice holes formed on both sides to be collected and discharged.

[0018] In addition, an upward-flow modular inclined plate sedimentation device having a hybrid structure is provided, characterized in that a cleaning nozzle is provided along the longitudinal direction on the upper part of the first inclined plate module, the nozzle is connected so as to be rotatable in a frontal spray form, sprays through an angled slit formed in the tapered part of the nozzle end, and rotates by water pressure when spraying at an angle. Effects of the invention

[0019] According to the present invention, an upward-flow modular inclined plate sedimentation device comprising a primary inclined plate module in which four sides of an inclined pipe are attached to each other to form a certain pattern, and a frame-shaped secondary inclined plate module in which the primary inclined plate module is installed inside, wherein the primary inclined plate module is supported by a lower horizontal support member and a lower support member, and the primary inclined plate module is prevented from rising due to buoyancy by a horizontal support member and a buoyancy prevention member at the top, and further including a triangular tension structure member at the side, thereby sufficiently supporting the primary inclined plate module when its weight is substantial when assembled within the secondary inclined plate module, preventing the primary inclined plate module from rising due to buoyancy, and maximizing the load-bearing capacity of the secondary inclined plate module, can be provided.

[0020] In addition, an upward-flow modular inclined plate sedimentation device comprising a primary inclined plate module in which four sides of an inclined pipe are attached to form a certain pattern, and a secondary inclined plate module in the form of a frame that allows the primary inclined plate module to be installed inside, can be provided with a hybrid structure that maximizes the projected area to increase the sedimentation efficiency of the flux in a certain space by configuring an inclined pipe in which the cross-section of the primary inclined plate module is trapezoidal or hexagonal and the height is low and the spacing of the inclined plates is close.

[0021] In addition, according to the present invention, when used to remove sludge with a slow settling rate, i.e., fine flocs, the settling efficiency can be improved by installing the inclined plate close to the lightweight inclined plate to increase the projected area, and the length of the inclined plate can also be reduced, thereby minimizing the installation space for the inclined plate. When improving existing structures, the space under the inclined plate can be maximized, and when applied to new structures, the height of the structure can be reduced, making it economical.

[0022] In addition, in the case of conventional inclined pipe modules manufactured by assembling lightweight inclined plate sheets, assembly is carried out on-site, which increases the on-site installation period and raises concerns about contamination and damage during the assembly process. Although manufacturing the inclined pipe module in a factory and installing it on-site can resolve the disadvantages of on-site assembly, other problems such as damage and deformation of the inclined pipe module may occur during on-site transportation, storage, and installation after manufacturing. However, according to the present invention, since a secondary steel module with a primary inclined plate module installed inside is manufactured in a factory and then transported to the site for installation, problems such as damage to the inclined plate module can be fundamentally resolved.

[0023] In addition, the present invention can provide an upward-flow modular inclined plate sedimentation device having a hybrid structure that has a smaller volume than a conventional inclined plate, can be manufactured with a lightweight structure to reduce manufacturing and installation costs, and has sufficient strength with a small number of structural elements.

Specific details for implementing the invention

[0025] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In describing the present invention, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions may obscure the essence of the present invention. In order to clearly explain the present invention in the drawings, parts unrelated to the explanation have been omitted, and similar parts throughout the specification have been given similar reference numerals. Furthermore, the orientation of the detailed configurations shown in the inclined plate sedimentation device is described based on the drawings. Additionally, throughout the specification, when a part is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0027] FIG. 1 is a perspective view showing an upward-flow modular inclined plate sedimentation device having a hybrid structure according to an embodiment of the present invention, FIG. 2 to 4 are a plan view (including a partially enlarged view), a side view, and a front view (including a partially enlarged view), respectively, showing the upward-flow modular inclined plate sedimentation device having a hybrid structure according to an embodiment of the present invention connected, and FIG. 5 is a perspective view showing a secondary steel module in an embodiment of the present invention. FIG. 2 illustrates the case where the cross-section of the inclined pipe is hexagonal (a) and the case where it is trapezoidal (Fig. 4b), respectively.

[0028] Referring to FIGS. 1 to 5, an upward-flow modular inclined plate sedimentation device (100) installed inside a sedimentation tank having a hybrid structure according to the present invention includes a primary inclined plate module (200) and a secondary steel module (300), and the secondary steel module (300) includes a horizontal support member (310), a vertical reinforcement member (320), a lower support member (330), a buoyancy prevention member (340), and a triangular tension structure member (350).

[0029] The upward-flow modular inclined plate sedimentation device (100) having a hybrid structure according to the present invention becomes a single assembly unit in a system in which modularization, that is, the assembly of the primary inclined plate module (200) and the secondary steel module (300) is completed during the manufacturing process, and unit modules (U) are connected and installed at the site. FIG. 2 shows a configuration in which 4×7 modules are connected.

[0030] The above first inclined plate module (200) is an inclined plate module installed inside the above second forced module (300), wherein vertical surfaces of inclined pipes (210) made of non-metallic material that are inclined at a certain angle are attached to each other to form a certain pattern. Here, the vertical surface (211) forms a side in the inclined direction, and the inclined surface (212) forms a front or back in the inclined direction.

[0031] The above-mentioned inclined pipe (210) is arranged in multiple numbers in the sedimentation device (100) to maximize sedimentation performance. It is installed at a certain angle in the longitudinal direction of the module, and raw water flowing into the lower part of the module comes into contact with it, causing the floc to slide along the inclined surface (212) for a short distance and settle quickly. At this time, the above-mentioned inclined pipe (210) is a tubular inclined plate. Unlike a typical upward-flow inclined plate which has a thickness of 2 to 3 mm, the thickness of the inclined plate is reduced to about 1 mm or less to reduce weight. At the same time, the inclined surface (212) where the floc settles is a single layer so that they do not stick together, thereby preventing the floc from sticking to the inclined plate due to fine shaking caused by the flow velocity, or allowing attached sludge to detach. Additionally, by narrowing the gap between the inclined plates, a large projected area can be achieved, making it effective for raw water treatment such as water purification and tertiary sewage treatment. In this regard, the material of the above-mentioned inclined pipe (210) is a non-metallic material such as ABS or PVC.

[0032] In the present invention, it is preferable that the inclined pipe (210) has a cross-section in the shape of a trapezoid or a hexagon and has a low height so that the distance is short. This allows for maximizing the projected area to increase the sedimentation efficiency of flocs in a certain space by keeping the spacing close, while minimizing interference during floc sedimentation.

[0033] In addition, the inclined pipe (210) is made of a non-metallic material and can be modularized by using an adhesive (B) to attach the vertical surface (211) long so that it is formed long when connecting the inclined pipe for long-term use. This can solve the problems of breakage and detachment (see FIG. 6) that occur in the conventional assembly method using a stapler during flow or cleaning. In addition, the inclined surface (212) is a single layer and maintains a thin inclined surface (212) so that floc does not adhere to the inclined pipe (210) due to fine shaking caused by the flow velocity, or so that attached sludge is detached.

[0034] The above secondary steel module (300) is a frame-shaped module that allows the above primary inclined plate module (200) to be installed inside, and includes a horizontal support member (310), a vertical reinforcement member (320), a lower support member (330), a buoyancy prevention member (340), and a triangular tension structure member (350) in order to sufficiently support the primary inclined plate module (200) assembled within the secondary steel module (300) when the weight is substantial, prevent the primary inclined plate module (200) from rising due to buoyancy, and maximize the load-bearing capacity of the secondary steel module (300).

[0035] The above horizontal support member (310) is provided with square pipes at four edge positions on the top and bottom perimeters, that is, at each of the top and bottom edges, so that the first inclined plate module is supported (or covered) at the bottom and also prevents the first inclined plate module (200) from rising upward, thereby serving to hold the perimeter of the module when load and buoyancy are applied to the first inclined plate module (200).

[0036] The vertical reinforcement member (320) connects the upper horizontal support member (311) and the lower horizontal support member (312) at the four corners, thereby ensuring that the secondary steel module (300) maintains its basic frame structure. At this time, the vertical reinforcement member (320) is fixedly provided on the outer surface of each of the upper horizontal support member (311) and the lower horizontal support member (312) with a cross-section in the shape of an L, so that the primary inclined plate module (200) is supported at the bottom at each of the four corners and prevents it from rising upward. This vertical reinforcement member (320) is a structure capable of providing sufficient strength without occupying space. Additionally, the cross-section is formed vertically to minimize the surface area for sludge attachment.

[0037] At this time, the upper horizontal support member (311) can have its outer surface made the same as the lower horizontal support member (312) and its width reduced so that the area where sludge accumulates at the top can be minimized, and specifically, the ratio of width to height can be made to about 1:2 so that sagging can be prevented.

[0038] The lower support member (330) is connected by a square pipe between the lower horizontal support members (312) in the longitudinal direction and supports the first inclined plate module (200) by extending it, thereby distributing and supporting the load of the first inclined plate module (200) which is concentrated in the relatively central part as the first inclined plate module (200) is extended long.

[0039] The above buoyancy prevention member (340) is connected in the form of a vertical bar between the upper horizontal support members (311) to prevent temporary rise when sludge accumulates in the first inclined plate module (200), so that the first inclined plate module (200) is extended long and the rise due to buoyancy of the first inclined plate module (200) is prevented in the relatively central part. At this time, the buoyancy prevention member (340) is provided connected in the vertical direction in the form of a thin bar, that is, provided without a flat structure so that sludge accumulation can be minimized.

[0040] The above triangular tension structure (350) is connected in the form of a vertical bar (351) and a diagonal bar (352) between the upper horizontal support (311) and the lower horizontal support (312) in the longitudinal direction to reinforce the load-bearing capacity of the secondary steel module (300). The vertical bar (351) can be fixed, for example, by connecting from the outer surface of the upper horizontal support (311) to the outer surface of the lower horizontal support (312) in the same line as the buoyancy prevention part (340), and the diagonal bar (352) can also be fixed by connecting from the outer surface of the upper horizontal support (311) to the outer surface of the lower horizontal support (312) in a diagonal direction between the vertical bar (351). In this way, the vertical bar (351) and diagonal bar (352) are connected to form a triangular tension structure (350). Unlike conventional X-shaped structures, this allows for the implementation of a structure capable of resisting tension and vertical loads by minimizing the dead space of the module without adding thickness to the reinforcing member on the side, thereby enabling the primary inclined plate module (200) to be supported and maintained with lightweight materials.

[0041] In addition, the square upper surface of the lower horizontal support member (312) is connected to the lower support member (330) so that the first inclined plate module (200) can be placed across it, thereby enabling stable support of the first inclined plate module (200), which has its own structure and is attached with adhesive. More specifically, the upper surface of the lower horizontal support member (312) has an inner space so that the first inclined plate module (200) can be placed thereon, and the assembly method can be described as an assembly method that integrates the first inclined plate module (200) and the second inclined plate module (300) without any gaps by wrapping them with the triangular tension structure member (350), etc.

[0042] In the present invention, the method of connecting (combining) the elements forming the secondary steel module (200) is not particularly limited, but the horizontal support member (310), the vertical reinforcement member (320), and the lower support member (330) can be joined by welding as they are provided as square pipes, and the buoyancy prevention member (340) and the triangular tension structure member (350) can be joined by rivets as they are provided in the form of bars. At this time, the rivet joining of the buoyancy prevention member (340) and the triangular tension structure member (350) can be performed after assembling the primary inclined plate module (200) to the secondary steel module (300).

[0043] FIG. 7 is a plan view, a front view, and a partially enlarged view illustrating a method of assembling secondary forced modules in one embodiment of the present invention.

[0044] Referring to FIG. 7, the assembly method between the secondary steel modules (300) in the present invention can be achieved by using a bolt (361) and a nut (362) to secure the upper horizontal support (311) through a wedge dog structure (360) equipped with a bolt hole formed on the inner side of the upper horizontal support (311) to secure the connection between the modules more firmly.

[0045] The above wedge dog structure (360) has a sturdy assembly structure that disperses the concentrated load of the lightweight secondary steel module (300), thereby reinforcing the protection and assembly of the upper horizontal support (311).

[0046] FIG. 8 is a plan view, a front view, and a partially enlarged view for explaining an upward-flow modular inclined plate sedimentation device having a hybrid structure with an inspection inclined plate installed in one embodiment of the present invention, FIG. 9 is a side view of the inspection inclined plate in FIG. 8, and FIG. 10 and 11 are a front view showing the appearance with a cleaning nozzle installed and a cross-sectional view showing the nozzle structure, respectively.

[0047] Referring to FIG. 9 and 9, in the present invention, an inspection inclined plate (370) is installed on the upper part of the primary inclined plate module (200), thereby providing a means for an operator to move to inspect the inclined plate sedimentation device (100).

[0048] The above inspection inclined plate (370) is structured such that a bent flow guide plate (371) is connected to guide plates (372) on both sides, wherein the guide plates (372) are positioned on the upper horizontal support (311), and the bent flow guide plate (371) is connected and positioned between the upper horizontal support (311) and the guide plates (372) in the longitudinal direction. Accordingly, the inspection inclined plate (370) provides a means for a user to move, while also allowing the direction of the treated water to be controlled by guiding the direction of the residual flow from the direction of the inflow water at the bottom of the inclined plate according to the installation angle of the flow guide plate (371). This prevents short-circuiting, allowing the fluid to rise at a constant flow rate and increasing the efficiency of the inclined plate.

[0049] The bent angle (θ) of the above flow guide plate (371) can be 45 to 75° with respect to the horizontal plane, preferably 55 to 65°, and most preferably 60°, so that sludge can settle and flow down.

[0050] When an inspection inclined plate (370) having a flow-guiding function is installed as described above, the same method as the wedge dog assembly method of the existing module can be used as a method of assembly between the second forced module (300). This can be achieved by fixing the guide plate (372) through using a bolt (361) and a nut (362) while the wedge dog structure (360), which is equipped with a bolt hole formed on the inner surface of the upper horizontal support member (311) and the guide plate (372), surrounds the upper horizontal support member (311) and the guide plate (372).

[0051] In the present invention, a trough (400) may be installed on the upper part of the first inclined plate module (200) to allow treated water processed through the inclined plate to overflow through a plurality of orifice holes formed on both sides, thereby collecting and discharging it. At this time, referring to FIG. 9, the trough (400) is provided with a cleaning nozzle (380) along a longitudinal pipe (390) at the bottom, and the nozzle (380) and the pipe (390) are installed in the longitudinal direction of the trough (400), so that the nozzle (380) is sprayed in a rotary spray form, generating waves while rotating, thereby increasing the cleaning efficiency of the inclined plate.

[0052] Also, referring to FIG. 11, the cleaning nozzle (380) is provided along the longitudinal direction on the upper part of the primary inclined plate module (200), and the nozzle (380) is connected so as to be rotatable in a front spray form, and sprays through an angled slit (382) formed in the tapered portion (381) at the end of the nozzle, and by causing the spray to rotate due to water pressure when spraying through the angled slit (382), the cleaning efficiency of the inclined plate can be further improved.

[0054] Preferred embodiments of the present invention have been described in detail above with reference to the drawings. The description of the present invention is for illustrative purposes only, and those skilled in the art will understand that other specific forms can be easily modified without changing the technical concept or essential features of the present invention.

[0055] Accordingly, the scope of the present invention is defined by the claims set forth below rather than by the detailed description above, and all modifications or variations derived from the meaning, scope, and equivalent concepts of the claims should be interpreted as being included within the scope of the present invention.
