Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to a device for preventing siltation and water blockage. Background Technology

[0002] During heavy rainstorms, rainwater carries a large amount of mud, sand, floating debris, oil, and other mixtures into underground pipelines. These complex mixtures not only pollute the pipeline system but also cause blockages.

[0003] Currently, conventional sump pits mainly serve to collect water and have virtually no water treatment capabilities. Some sump pits only have filters at the inlet to intercept floating debris. However, this simple interception method is prone to clogging due to the accumulation of debris, and it can only intercept larger floating objects. It is difficult to effectively block large amounts of suspended mud, oil, and other impurities in the water. These particles will flow with the water into the next level of the pipe network, which may cause clogging or pollution of the next level of the pipe network, seriously affecting the normal operation of the drainage system. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an anti-siltation and water treatment device that can intercept floating and suspended matter, promote sedimentation, prevent downstream pipes from being contaminated and blocked by the accumulation of debris and silt, ensure the smooth flow of the drainage system, and improve water quality.

[0005] The anti-siltation and water blockage treatment device according to an embodiment of the present invention includes a sedimentation tank with an inlet pipe and an outlet pipe; a cover plate covering the open end of the sedimentation tank, with several ventilation holes, the cover plate being used to prevent personnel and objects from falling into the sedimentation tank; a cover body disposed inside the sedimentation tank, the cover body having an opening facing the bottom of the sedimentation tank, the cover body being connected to the outlet pipe, the open end of the cover body being lower than the outlet pipe, and water flowing sequentially through the inlet pipe, sedimentation tank, cover body and outlet pipe; and an anti-siphon pipe disposed on the cover body, the anti-siphon pipe connecting the cover body and the outside air, the anti-siphon pipe being used to balance the air pressure between the cover body and the outside air to prevent siphoning.

[0006] The anti-siltation and water blockage treatment device according to the embodiments of this utility model has at least the following beneficial effects: The sedimentation tank serves as the main container, and the cover, inlet pipe, and outlet pipe inside form a graded treatment path. When rainwater mixed with floating matter, suspended matter, and other impurities flows into the sedimentation tank from the inlet pipe, the water flow must first flow towards the bottom opening of the cover within the tank, rise inside the cover, and then flow out through the drain pipe. This path pattern utilizes buoyancy to prevent floating matter on the water surface from entering the next stage of the pipeline. The grid, with its square grid of a certain height, prevents the water from forming eddies in the sedimentation tank, thereby reducing the rainwater's ability to carry impurities and preventing floating matter from being sucked into the downstream pipeline. The cover maintains air pressure balance through the anti-siphon pipe, preventing negative pressure from being generated and avoiding a siphon between the device and the downstream pipeline, thus maintaining a stable water level in the sedimentation tank at a higher position and promoting sedimentation. As water flows upward through the opening of the enclosure, the resistance components cause the water to flow in a detour, reducing the flow velocity and creating a slow-flow zone. This allows suspended sediment to settle secondary inside the enclosure. Under the pressure balancing effect of the anti-siphon pipe, the purified water is finally discharged from the high-level outlet pipe. This achieves cascade treatment of complex pollutants, avoids contamination of lower-level pipes and blockages caused by debris and sediment accumulation, ensures smooth drainage, and improves water quality.

[0007] According to some embodiments of the present invention, a grating is also included. The grating is disposed in the sedimentation tank and located below the inlet pipe. The grating is used to prevent the water in the sedimentation tank from forming vortices.

[0008] According to some embodiments of the present invention, a filter screen is also included. The filter screen is disposed at the opening end of the cover and is used to block some of the escaped floating objects and the suspended objects that have not been deposited in the sedimentation tank from entering the cover.

[0009] According to some embodiments of the present invention, a resistance component is also included. The resistance component is disposed on the cover and located below the water outlet pipe. The resistance component is configured to reduce the flow velocity by extending the water flow path.

[0010] According to some embodiments of the present invention, the resistance component includes: a plurality of first resistance plates, all of which are disposed on the inner wall of the cover, and the plurality of first resistance plates are arranged sequentially at intervals along the extension direction of the cover; a plurality of second resistance plates, all of which are disposed on the inner wall of the cover, and the plurality of second resistance plates are arranged sequentially at intervals along the extension direction of the cover, and the plurality of second resistance plates and the plurality of first resistance plates are alternately arranged to form a meandering fluid channel.

[0011] According to some embodiments of this utility model, the cover and the sedimentation tank are detachably connected.

[0012] According to some embodiments of the present invention, a first fastening member is provided on the cover, and a second fastening member adapted to the first fastening member is provided on the wall of the sedimentation tank. The first fastening member and the second fastening member cooperate to realize the detachable connection between the cover and the sedimentation tank.

[0032] refer to Figures 1 to 4 This embodiment discloses a water treatment device for preventing siltation and blockage.

[0033] like Figures 1 to 4 As shown, the anti-siltation and water blockage treatment device includes a sedimentation tank 100, a cover plate 200 covering the open end of the sedimentation tank 100, a hood 300 disposed inside the sedimentation tank 100, and an anti-siphon pipe 400 disposed on the hood 300. The sedimentation tank 100 is equipped with an inlet pipe 110 and an outlet pipe 120. The cover plate 200 has several ventilation holes 210 and is used to intercept floating debris. The hood 300 has an opening facing the bottom of the sedimentation tank 100 and is connected to the outlet pipe 120. The open end of the hood 300 is lower than the outlet pipe 120, and water flows sequentially through the inlet pipe 110, the sedimentation tank 100, the hood 300, and the outlet pipe 120. The anti-siphon pipe 400 connects the hood 300 to the outside air and is used to balance the air pressure between the hood 300 and the outside air to prevent siphoning.

[0034] like Figure 1As shown, the cover 300 is disposed inside the sedimentation tank 100, with the opening end of the sedimentation tank 100 facing upwards and the opening end of the cover 300 facing downwards. The top of the cover 300 is provided with an anti-siphon pipe 400 for connecting the inner cavity of the cover 300 with the outside air. A water inlet pipe 110 and a water outlet pipe 120 are respectively disposed on two opposite walls of the sedimentation tank 100, wherein the water outlet pipe 120 is connected to the inside of the cover 300. Therefore, the sedimentation tank 100 serves as the main container, and the cover 300, inlet pipe 110, and outlet pipe 120 inside it form a graded treatment path. The cover 300 maintains air pressure balance through the anti-siphon pipe 400, and its opening end is lower than the outlet pipe 120. Water must rise inside the cover 300 before it can be discharged. When mixed rainwater flows into the sedimentation tank 100 from the inlet pipe 110, the floating objects blocked by the cover plate 200 form a surface filter layer. The water flow velocity decreases sharply, causing high-density impurities to settle naturally. When the water flows upward through the opening end of the cover 300, a slow flow zone is formed due to the change in the flow cross section, causing suspended silt to settle secondary inside the cover 300. Under the air pressure balance effect of the anti-siphon pipe 400, the purified water is finally discharged from the high-level outlet pipe 120, thus realizing the graded treatment of complex pollutants, avoiding blockage of pipes caused by the accumulation of debris and silt, ensuring the smooth flow of the drainage system, and reducing the risk of urban flooding.

[0035] Specifically, the inlet pipe 110 and the outlet pipe 120 are both located below the cover plate 200, and the inlet pipe 110 and the outlet pipe 120 are horizontally arranged and located on the same horizontal line.

[0036] In some specific embodiments of this utility model, a grid 500 is also included. The grid 500 is disposed in the sedimentation tank 100 and is located on the lower side of the water inlet pipe 110. The grid 500 is used to prevent the water in the sedimentation tank 100 from forming vortices.

[0037] like Figure 1 and Figure 2 As shown, the grid 500 is located between the inlet pipe 110 and the opening of the shroud 300, and is horizontally embedded between the shroud 300 and the sedimentation tank 100. It should be noted that the downward-then-upward flow of water allows suspended solids to be intercepted by buoyancy, preventing them from entering the shroud 300. However, when the water enters from the bottom of the shroud 300 and generates vortices, the vortex increases the flow velocity and also pulls in floating solids that would otherwise be difficult to sink. Therefore, the grid 500 is added inside the sedimentation tank 100 to suppress potential eddy currents. Specifically, the grid 500 is located below the inlet pipe 110. When high-speed water enters the sedimentation tank 100, the grid 500 divides the water flow into independent fluids, guiding the water flow into a laminar state, disrupting the conditions for vortex formation, and reducing the disturbance of the settled sludge to prevent sludge from being drawn into the shroud 300, ensuring that the sedimentation effect is not disturbed.

[0038] It should be noted that the bar screen, with its square grid of a certain height, prevents the water from forming eddies in the sedimentation tank, thereby reducing the rainwater's ability to carry debris and preventing floating objects from being sucked into downstream pipes. Since a bar screen that is too small will result in excessive water flow resistance, while a bar screen that is too large will fail to break the water flow rotation, and a bar screen that is too low will not prevent eddies, the size and height of the bar screen's openings are limited. Specifically, the grid size of bar screen 500 is 5cm to 10cm, and the bar screen height should preferably be 1 / 5 to 1 / 3 of the internal height of sedimentation tank 100, and not less than 10cm.

[0039] In some specific embodiments of this utility model, a filter screen 600 is also included. The filter screen 600 is disposed at the opening end of the cover 300. The filter screen 600 is used to block some of the escaped floating objects and the suspended objects that have not been deposited in the sedimentation tank 100 from entering the cover 300.

[0040] like Figure 1 and Figure 3 As shown, the filter screen 600 is located at the open end of the lower part of the cover 300, further enhancing its ability to intercept some of the escaped suspended impurities. Specifically, the filter screen 600 is located at the inlet where the water flows into the cover 300. When some light floating objects and suspended particles flow towards the cover 300 with the water flow, the filter screen 600 will trap them outside the cover 300, while the treated water flows upward into the interior of the cover 300 and is finally discharged from the outlet pipe 120.

[0041] It should be noted that the pore structure of the filter screen 600 can ensure sufficient water flow while effectively blocking tiny impurities. At the same time, the intercepted impurities can naturally fall back to the bottom of the sedimentation tank 100 under the action of water flow, avoiding the risk of clogging.

[0042] In some specific embodiments of this utility model, a resistance component 700 is also included. The resistance component 700 is disposed inside the cover 300 and located on the lower side of the water outlet pipe 120. By changing the direction of water flow and increasing the length of the flow path, the water flow is forced to form a more complex motion trajectory inside the cover 300, thereby prolonging the settling time of suspended particles and allowing the water to undergo a more thorough sedimentation process before being discharged.

[0043] In some specific embodiments of this utility model, the resistance component 700 includes a plurality of first resistance plates 710, which are all disposed on the inner wall of the cover 300 and are arranged at intervals along the extension direction of the cover 300; and a plurality of second resistance plates 720, which are all disposed on the inner wall of the cover 300 and are arranged at intervals along the extension direction of the cover 300. The plurality of second resistance plates 720 and the plurality of first resistance plates 710 are alternately arranged to form a meandering fluid channel.

[0044] like Figure 1 and Figure 2 As shown, multiple first resistance plates 710 are sequentially arranged vertically on the left inner wall of the enclosure 300, and multiple second resistance plates 720 are sequentially arranged vertically on the right inner wall of the enclosure 300. The multiple first resistance plates 710 and multiple second resistance plates 720 are arranged alternately, thereby constructing a meandering water flow channel within the enclosure 300, which significantly optimizes the sedimentation and separation effect. Specifically, the interlaced first resistance plates 710 and second resistance plates 720 form a continuous S-shaped movement trajectory below the outlet pipe 120. Each time the water flows past a resistance plate, the flow velocity further decreases, thereby promoting the deposition of suspended solids in the water flow outside the enclosure.

[0045] In some specific embodiments of this utility model, the cover 300 and the sedimentation tank 100 are detachably connected. During drainage operations, the close cooperation ensures that the water flows strictly through the sedimentation tank 100 and the cover 300 along the preset path, maintaining the established sedimentation treatment effect. When maintenance is required, the connection can be quickly disconnected to thoroughly clean the deposited sludge, thereby ensuring that the entire system maintains the best treatment efficiency under complex environmental conditions.

[0046] In some specific embodiments of this utility model, a first fastening member 310 is provided on the cover 300, and a second fastening member 130 adapted to the first fastening member 310 is provided on the wall of the sedimentation tank 100. The first fastening member 310 and the second fastening member 130 cooperate to realize the detachable connection between the cover 300 and the sedimentation tank 100. Figure 4 As shown, the first fastening member 310 is a sliding groove on the cover 300, and the second fastening member 130 is a sliding rail on the wall of the sedimentation tank 100. When the sliding groove is fitted onto the sliding rail, a connection interface with sufficient rigidity is formed to ensure that the cover 300 remains in corresponding communication with the outlet pipe 120 under the impact of high-speed water flow, maintaining the preset sedimentation flow state. When it is necessary to clean the sediment or perform maintenance, the cover 300 can be easily separated from the sedimentation tank 100 by simply pulling it out, realizing the quick installation and disassembly of the cover 300.

[0047] In some specific embodiments of this utility model, the bar screen 500 is detachably connected to the sedimentation tank 100, which maintains the fluid distribution function of the bar screen 500 under normal operating conditions and ensures maintenance efficiency through convenient disassembly. Specifically, in operation, the bar screen 500 remains firmly installed, and its pore structure evenly disperses the incoming water and eliminates vortices. When the pores of the bar screen 500 are blocked by debris, affecting the flow capacity, the connection can be quickly disconnected and the debris removed for cleaning.

[0048] Specifically, the grille 500 can be connected by sliding rail slots, magnetic sealing, rotating buckle, or pin positioning. These are all commonly used quick-release connection methods, and will not be described in detail here.

[0049] Specifically, the planar shape of the grid 500 matches the shape of the inner wall of the sedimentation tank 100 and the outer wall of the cover 300.

[0050] In some specific embodiments of this utility model, the diameter of the outlet pipe 120 is larger than the diameter of the inlet pipe 110.

[0051] Specifically, the diameters of the inlet pipe 110 and the outlet pipe 120 are determined by flow rate calculation. The diameter of the inlet pipe is 0.9 times that of the outlet pipe, the depth of the sedimentation tank is not less than 3 times the inner diameter of the outlet pipe, and the distance between the bottom of the cover and the top surface of the sediment is not less than 10cm.

[0052] In some specific embodiments of this utility model, the cover plate 200 covers the top of the sedimentation tank 100 with a structure having ventilation holes 210. The sedimentation tank 100 serves as a basic container, and its interior uses a grid 500 connected by a sliding rail slot to achieve uniform water distribution and vortex suppression. The cover 300 is quickly assembled and disassembled by the cooperation of the sliding rail and the sliding groove on the inner wall of the sedimentation tank 100. The cover 300 is provided with alternating first resistance plates 710 and second resistance plates 720 to form a meandering flow channel. A replaceable filter screen 600 is installed at the opening end, which, together with the anti-siphon pipe 400, forms a complete air pressure balance system. When rainwater and sewage rush into the sedimentation tank 100 through the inlet pipe 110, they first pass through the impact grid 500 plate and are dispersed into a uniform water flow, eliminating the vortex effect and promoting the initial sedimentation of large particles of impurities. During the upward flow of water, the floating particles are first intercepted by the filter screen 600 at the opening end of the cover 300 and then enter the interior of the cover 300. Then, multiple deflections are generated in the meandering channel formed by the alternating first resistance plate 710 and second resistance plate 720, so that the suspended particles can be fully settled in the extended hydraulic path. Finally, the treated rainwater is discharged from the outlet pipe 120.

[0053] It should be further noted that, for ease of later maintenance and cleaning, the shroud 300 and the sedimentation tank 100 are detachably connected, as are the grille 500 and the sedimentation tank 100. Specifically, after the device has been running for a period of time, if floating debris accumulates below the cover plate 200, maintenance personnel can directly remove the floating debris without interrupting the water flow. When it is necessary to clean the sediment, simply removing the grille 500 is sufficient to directly remove the sludge accumulated at the bottom of the sedimentation tank 100. If further cleaning of the interior of the shroud 300 is required, the entire shroud 300 can be removed to thoroughly clean internal components such as the filter screen 600 and the resistance component 700. This detachable structural design not only enables independent maintenance of each functional component but also improves the ease of cleaning the device and the efficiency of component replacement, ensuring the long-term stable operation of the system.

[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
