Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a flow-limiting interception well and a wastewater treatment system. Background Technology

[0002] An interceptor well is a drainage facility specifically designed to intercept, collect, and pre-treat sewage or mixed stormwater runoff. On one hand, by concentrating sewage from pollution sources, it prevents untreated sewage from being directly discharged into natural water bodies (such as rivers and lakes), thus avoiding water pollution. On the other hand, interceptor wells can separate stormwater and sewage, retaining domestic sewage and initial rainwater runoff during the dry season into sewage pipes, while allowing excess rainwater to overflow into downstream drainage systems or surface water bodies, preventing pipe overload. Common interceptor well structures are prone to clogging by dirt and debris, affecting the smooth flow and normal use of the interceptor well. Utility Model Content

[0032] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] refer to Figure 1 As shown, an embodiment of this application provides a flow-limiting interception well 100, which includes an interception well body 110 and a filter assembly 120.

[0034] Specifically, in combination Figure 1 and Figure 2 As shown, the intercepting well body 110 is provided with an inlet pipe 111 and an overflow pipe 112. The filter assembly 120 includes a filter element 121, a fixing element 122, and a movable element 123. The fixing element 122 is installed at the bottom of the intercepting well body 110. One end of the filter element 121 is rotatably connected to the fixing element 122. The end of the filter element 121 away from the fixing element 122 is hinged to one end of the movable element 123. The end of the movable element 123 away from the filter element 121 passes through the side wall of the intercepting well body 110 and extends to the outside. The filter element 121 is located between the output end of the inlet pipe 111 and the input end of the overflow pipe 112.

[0035] In this embodiment, when the filter element 121 rotates relative to the inlet pipe 111, the filter element 121 moves closer to or away from the output end of the inlet pipe 111. The inlet pipe 111 of the flow-limiting intercepting well 100 introduces sewage or rainwater overflow for treatment. The overflow pipe 112 is used to divert the overflow water to lower the water level. The filter element 121 is installed between the output end of the inlet pipe 111 and the input end of the overflow pipe 112. Moving the filter element 121 forward to the position of the inlet pipe 111 prevents garbage from clogging other pipes. The filter element 121 can rotate relative to the inlet pipe 111 through the fixing member 122. The filter element 121 moves closer to or away from the inlet pipe 111. The movable member 123 is used to adjust the tilt angle and position of the filter element 121, so that the tilt angle of the filter element 121 can be adjusted to suit different water flow rate changes, reducing the possibility of the filter element 121 being blocked or damaged when isolating dirt and screening garbage, and avoiding affecting drainage.

[0036] It is understandable that an intercepting well is a facility used to intercept, collect, and pre-treat sewage. Its main function is to prevent sewage from being directly discharged into natural water bodies (such as rivers and lakes), while reducing the load on sewage treatment plants and improving the efficiency of drainage systems. An intercepting well can concentrate sewage from multiple pollution sources (such as manholes) into a single well and guide it to the sewage treatment plant through pipelines, avoiding separate connections for each pipeline, thereby reducing construction costs and space occupation. During dry weather, sewage is intercepted and diverted into the downstream sewage network of a separate drainage system, while during rainy weather, mixed water exceeding the designed interception capacity overflows into the downstream rainwater system, thus improving water quality. The inventors of this application discovered in their research that because the intercepting well has a screen installed at the location of the intercepting pipe 113, and the upstream pipe contains a large amount of impurities such as kitchen waste and household garbage, the intercepting well is prone to blockage at the pipe inlet / outlet or the screen during daily use. The solution of this application is used to reduce blockage of the filter element 121 and the pipe, ensuring the diversion effect of the flow-limiting intercepting well 100.

[0037] refer to Figure 1 and Figure 2 As shown, the flow-limiting intercepting well 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X refers to the length direction of the flow-limiting intercepting well 100, the second direction Y refers to the height direction of the flow-limiting intercepting well 100, and the third direction Z refers to the width direction of the flow-limiting intercepting well 100. It is understood that the above definitions are only for the purpose of understanding the relative positional relationships of the various parts in the flow-limiting intercepting well 100 and should not be construed as limitations on this application.

[0038] In one embodiment, alternatively, referencing Figure 2 and Figure 3As shown, the fixing member 122 includes a first fixing plate 1221 and a second fixing plate 1222. The first fixing plate 1221 and the second fixing plate 1222 are detachably connected and together define a mounting hole 1223. The filter element 121 passes through the mounting hole 1223, and the filter element 121 is rotatably connected to the hole wall of the mounting hole 1223. In other words, the first fixing plate 1221 and the second fixing plate 1222 can be disassembled and assembled to facilitate the disassembly and replacement of the filter element 121 and to facilitate maintenance. The filter element 121 can rotate relative to the wall of the mounting hole 1223. The filter element 121 forms a certain angle with the direction of the incoming water flow to intercept garbage and dirt. For example, when the filter element 121 is impacted by the water flow or under the action of external force, the filter element 121 can rotate to adjust the angle between the filter element 121 and the second direction Y and the position of the filter element 121, thereby reducing the impact on the filter element 121, avoiding damage to the filter element 121, and improving the service life of the filter element 121.

[0039] In one embodiment, alternatively, such as Figure 3 As shown, the movable component 123 includes a first connecting chain 1231 and a movable pull ring 1232. The movable pull ring 1232 is installed on the side wall inside the intercepting well body 110. One end of the first connecting chain 1231 passes through the movable pull ring 1232 and extends to the outside of the intercepting well body 110. The first connecting chain 1231 is movably connected to the movable pull ring 1232. The end of the first connecting chain 1231 away from the movable pull ring 1232 is hinged to the filter element 121. Correspondingly, the movable pull ring 1232 and the first connecting chain 1231 form a movable snap-fit ​​structure to facilitate the connection and limitation of the first connecting chain 1231. The first connecting chain 1231 can move relative to the movable pull ring 1232. By pulling the first connecting chain 1231, the first connecting chain 1231 drives the filter element 121 to move, thereby adjusting the relative position of the filter element 121.

[0040] In one embodiment, alternatively, referencing Figure 2 and Figure 4 As shown, the flow-limiting intercepting well 100 also includes a flow-limiting component 130. The intercepting well body 110 is also provided with a sewage intercepting pipe 113. The flow-limiting component 130 is disposed at the input end of the sewage intercepting pipe 113, and the flow-limiting component 130 moves relative to the input end of the sewage intercepting pipe 113 to adjust the cross-sectional area of ​​the input end of the sewage intercepting pipe 113. Correspondingly, adjusting the position of the flow-limiting component 130 changes the cross-sectional area of ​​the input end of the sewage intercepting pipe 113, thereby controlling the flow rate of the sewage intercepting pipe 113 and preventing a large amount of mixed water from entering the sewage intercepting pipe 113, thus achieving the management and control of the sewage intercepting pipe 113.

[0041] In summary, the inlet pipe 111 of the flow-limiting intercepting well 100 introduces sewage or rainwater overflow for treatment, the overflow pipe 112 is used to divert the overflow water to lower the water level, the filter element 121 is installed between the output end of the inlet pipe 111 and the input end of the overflow pipe 112, the filter element 121 is moved forward to the position of the inlet pipe 111 to prevent garbage from clogging other pipes, the filter element 121 can rotate relative to the fixed part 122, the filter element 121 can move closer to or away from the inlet pipe 111, the movable part 123 is used to adjust the tilt angle and position of the filter element 121, so that the tilt angle of the filter element 121 can be adjusted to suit different water flow rate changes, reduce the possibility of the filter element 121 being blocked or damaged when isolating dirt and screening garbage, avoid affecting drainage, improve the use effect of the filter element 121 and facilitate daily maintenance.

[0042] refer to Figure 1 As shown, an embodiment of this application provides another flow-limiting interception well 100, which includes an interception well body 110 and a filter assembly 120.

[0043] Specifically, in combination Figure 1 and Figure 2 As shown, an inlet pipe 111 and an overflow pipe 112 are respectively provided inside the intercepting well body 110. The filter assembly 120 includes a filter element 121, a fixing element 122, and a movable element 123. The fixing element 122 is installed at the bottom inside the intercepting well body 110. One end of the filter element 121 is rotatably connected to the fixing element 122. The end of the filter element 121 away from the fixing element 122 is hinged to one end of the movable element 123. The end of the movable element 123 away from the filter element 121 passes through the side wall of the intercepting well body 110 and extends to the outside. The filter element 121 is located between the output end of the inlet pipe 111 and the input end of the overflow pipe 112.

[0044] When the filter element 121 rotates relative to the inlet pipe 111, the filter element 121 moves closer to or away from the output end of the inlet pipe 111. The inlet pipe 111 of the flow-limiting intercepting well 100 introduces sewage or rainwater overflow for treatment. The overflow pipe 112 is used to divert the overflow water to lower the water level. The filter element 121 is installed between the output end of the inlet pipe 111 and the input end of the overflow pipe 112. Moving the filter element 121 forward to the position of the inlet pipe 111 prevents garbage from clogging other pipes. The filter element 121 can rotate relative to the inlet pipe 111 through the fixing member 122. The filter element 121 moves closer to or away from the inlet pipe 111. The movable member 123 is used to adjust the tilt angle and position of the filter element 121, so that the tilt angle of the filter element 121 can be adjusted to suit different water flow rate changes, reducing the possibility of the filter element 121 being blocked or damaged when isolating dirt and screening garbage, and avoiding affecting drainage.

[0045] In one embodiment, alternatively, referencing Figure 2 and Figure 3 As shown, the fixing member 122 includes a first fixing plate 1221 and a second fixing plate 1222. The first fixing plate 1221 and the second fixing plate 1222 are detachably connected and together define a mounting hole 1223. The filter element 121 passes through the mounting hole 1223 and is rotatably connected to the hole wall of the mounting hole 1223. In other words, the first fixing plate 1221 and the second fixing plate 1222 can be disassembled and assembled to facilitate the disassembly and replacement of the filter element 121 and to facilitate maintenance. The filter element 121 can rotate relative to the hole wall of the mounting hole 1223. The filter element 121 forms a certain angle with the direction of water flow to facilitate the interception of garbage and dirt.

[0046] Furthermore, a protrusion 1221a is formed on the side of the first fixing plate 1221 opposite to the second fixing plate 1222. The protrusion 1221a and the second fixing plate 1222 together define the mounting hole 1223. The bottom of the filter element 121 passes through the mounting hole 1223. The hole wall of the mounting hole 1223 is used to connect and limit the filter element 121. The filter element 121 can rotate relative to the position of the mounting hole 1223 to achieve the purpose of adjusting the position of the filter element 121. For example, the filter element 121 can be a grid or a filter frame, both of which can intercept and filter garbage or dirt. For example, the bottom grid bar of the grid element is aligned with the opening of the mounting hole 1223, and the grid bar passes through the hole defined by the protrusion 1221a and the second fixing plate 1222. The grid bar is clamped in the mounting hole 1223 by the outer edge of the protrusion 1221a and the second fixing plate 1222. The type of filter element 121 is not specifically limited, and the protrusion 1221a has an arc-shaped structure.

[0047] In one embodiment, alternatively, such as Figure 3As shown, the movable component 123 includes a first connecting chain 1231 and a movable pull ring 1232. The movable pull ring 1232 is installed on the side wall inside the intercepting well body 110. One end of the first connecting chain 1231 passes through the movable pull ring 1232 and extends to the outside of the intercepting well body 110. The first connecting chain 1231 is movably connected to the movable pull ring 1232. The end of the first connecting chain 1231 away from the movable pull ring 1232 is hinged to the filter element 121. Correspondingly, the movable pull ring 1232 and the first connecting chain 1231 form a movable snap-fit ​​structure to facilitate the connection and limitation of the first connecting chain 1231. The first connecting chain 1231 can move relative to the movable pull ring 1232. By pulling the first connecting chain 1231, the first connecting chain 1231 drives the filter element 121 to move, thereby adjusting the relative position of the filter element 121. For example, the first connecting chain 1231 is provided with multiple limiting parts, any of which can be movably engaged with the movable pull ring 1232.

[0048] In one embodiment, optionally, the movable component 123 is a telescopic rod and a movable pull ring 1232. The movable pull ring 1232 is installed on the side wall inside the intercepting well body 110. One end of the telescopic rod is hinged to the filter element 121, and the end of the telescopic rod away from the filter element 121 is movably connected to the movable pull ring 1232. Accordingly, one end of the telescopic rod can be movably connected to the movable pull ring 1232. The telescopic rod can extend and retract to adjust its length, so that the length of the telescopic rod changes according to the position of the filter element 121. The telescopic rod is used to connect the filter element 121 and will not interfere with the movement of the filter element 121.

[0049] In one embodiment, alternatively, referencing Figure 2 and Figure 4 As shown, the flow-limiting intercepting well 100 further includes a flow-limiting component 130. A sewage intercepting pipe 113 is also provided within the intercepting well body 110. The flow-limiting component 130 is located at the input end of the sewage intercepting pipe 113, and the flow-limiting component 130 can move relative to the input end of the sewage intercepting pipe 113 to adjust the cross-sectional area of ​​the input end of the sewage intercepting pipe 113. Correspondingly, adjusting the position of the flow-limiting component 130 changes the cross-sectional area of ​​the input end of the sewage intercepting pipe 113, thereby controlling the flow rate of the sewage intercepting pipe 113 and preventing a large amount of mixed water from entering the sewage intercepting pipe 113, thus achieving management and control of the sewage intercepting pipe 113. For example, the pipe height of the sewage intercepting pipe 113 is less than the pipe height of the overflow pipe 112.

[0050] Optionally, such as Figure 4As shown, the flow-limiting component 130 includes a flow-limiting plate 131, a second connecting chain 132, and a hook 133. The hook 133 is installed on the side wall inside the intercepting well body 110. The input end of the intercepting pipe 113 is provided with a slot 114, and the flow-limiting plate 131 can be engaged with the slot wall of the slot 114. One end of the second connecting chain 132 is connected to the flow-limiting plate 131, and the end of the second connecting chain 132 away from the flow-limiting plate 131 is detachably connected to the hook 133. Correspondingly, the flow-limiting plate 131... The limiting and fixing are achieved through the slot 114. The second connecting chain 132 drives the flow limiting plate 131 to move relative to each other in the second direction Y. After the second connecting chain 132 is lowered, it is ensured that the flow limiting plate 131 is engaged with the slot 114 to close or partially close the sewage interception pipe 113. The operator pulls the second connecting chain 132 to raise the flow limiting plate 131, so that the second connecting chain 132 can be detached from the hook 133 or hooked onto the second connecting chain 132. The position of the flow limiting plate 131 can be adjusted by adjusting the length of the second connecting chain 132.

[0051] Furthermore, the second connecting chain 132 is provided with a plurality of connecting buckles 1321 in sequence along its length. Each of the connecting buckles 1321 can be movably engaged with the hook 133. In other words, each connecting buckle 1321 can serve as a temporary fixing point between the second connecting chain 132 and the hook 133. By selecting connecting buckles 1321 at different positions to engage with the hook 133, multi-level adjustment of the relative position between the flow restrictor 131 and the input end of the intercepting pipe 113 can be achieved.

[0052] In one embodiment, alternatively, referencing Figure 5 As shown, the intercepting well body 110 has an inspection hole 140, which corresponds to the position of the hook 133. The position of the inspection hole 140 and the hook 133 are aligned, allowing the operator to directly operate the second connecting chain 132 through the inspection hole 140 using a hook-shaped tool without entering the intercepting well body 110, thereby adjusting the position of the flow limiting plate 131.

[0053] For example, the intercepting well body 110 is provided with a cover plate 150, which is used to cover the inspection hole 140 of the intercepting well body 110, and to protect the intercepting well body 110 and prevent external debris from entering the intercepting well body 110.

[0054] An embodiment of this utility model also provides a sewage treatment system, including the flow-limiting interception well 100 in the above embodiment. The sewage treatment system including the flow-limiting interception well 100 has all the beneficial effects of the flow-limiting interception well 100, which will not be described in detail here.

[0055] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0056] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
