Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and specifically to a wastewater treatment device based on urban water network ecosystem restoration. Background Technology

[0002] In the comprehensive management of urban water systems, it is often necessary to use wastewater treatment facilities to treat sewage flowing into the water network or polluted water bodies on-site to prevent the spread of pollutants. Currently, existing wastewater treatment facilities typically employ single or combined methods such as screen interception, sedimentation filtration, or chemical dosing.

[0003] However, in practical applications, existing wastewater treatment devices still have the following shortcomings: First, the interception efficiency of existing devices is often not adjustable, resulting in poor adaptability. Traditional interception devices mostly use filter screens or plates with fixed pore sizes, and once installed, their filtration accuracy and flow capacity are fixed. When the influent water quality is poor or the flow rate is large, fixed interception devices are prone to clogging, leading to a decrease in treatment efficiency or even equipment shutdown. Conversely, when the influent load is small, it is impossible to flexibly reduce the interception accuracy to increase the flow velocity according to demand, resulting in an unreasonable hydraulic retention time and affecting the overall treatment effect.

[0004] Secondly, existing devices lack the ability to adaptively adjust water volume and produce poor mixing results. The inflow of water into urban water networks often fluctuates significantly with rainfall or seasonal changes. In existing technologies, the diameter of the drainage outlet is usually fixed, making it impossible to automatically adjust the drainage speed according to water level changes. This easily leads to overflow at high water levels and excessively rapid drainage at low water levels, thus shortening treatment time. Furthermore, to enhance treatment effectiveness, chemicals are often added, but existing devices mostly rely on static mixing or require additional electric stirring equipment. The former results in uneven mixing, while the latter increases energy consumption and equipment complexity.

[0005] Therefore, it is necessary to provide a wastewater treatment device based on urban water network ecosystem restoration to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problems, the present invention provides the following technical solution: a sewage treatment device based on urban water network ecosystem restoration, comprising: an inlet pipe, one end of which is connected to the urban water network; a treatment chamber connected to the inlet pipe for treating sewage in the inlet pipe, wherein an interception component is provided in the treatment chamber; an installation pipe assembly disposed below the treatment chamber for adjusting the installation position of the treatment chamber; a measuring pipe installed below the installation pipe assembly for draining liquid; a detector disposed on one side of the measuring pipe for detecting the effluent quality of the measuring pipe; and a control chamber disposed above the treatment chamber, wherein a control component is also provided in the control chamber for adjusting the interception efficiency of the interception component.

[0007] Preferably, the interception assembly includes: an inner cylinder, one end of which is connected to the water inlet pipe and the other end of which is fixed to the inner wall of the treatment chamber; an outer cylinder, which is rotatably sleeved on the outside of the inner cylinder; a plurality of circumferentially distributed support rollers, which are rotatably disposed on the inner wall of the treatment chamber and support the outer cylinder; the inner cylinder has a plurality of first through holes; and the outer cylinder has a second through hole corresponding to the first through holes.

[0008] Preferably, the control assembly includes: a telescopic rod fixed in the control compartment; a first connecting rod fixed to the telescopic end of the telescopic rod; and a second connecting rod hinged between the first connecting rod and the outer cylinder.

[0009] Preferably, a cleaning rod is provided in the second through hole; the cleaning rod extends into the first through hole, and a relief groove corresponding to the cleaning rod is also provided on one side of the first through hole.

[0010] Preferably, a cleaning pipe is provided on the side of the treatment chamber away from the water inlet pipe, and the cleaning pipe is used to communicate with the inner cylinder.

[0011] Preferably, the treatment chamber is also equipped with an auxiliary tube for supplying the drug solution.

[0012] Preferably, the bottom of the processing chamber is integrally extended to form a processing tube, a partition is fixed in the processing tube, a plurality of third through holes are opened on the partition, a sliding rod is inserted through the third through hole, a float plate assembly is provided at the top of the sliding rod, and a stabilizing block and a limiting block are provided at the bottom. A gap is maintained between the sliding rod and the third through hole, and the outer diameter of the sliding rod gradually decreases from top to bottom.

[0013] Preferably, the float assembly includes: a sleeve fixed to the slide rod; a plurality of elastic plates fixed to the sleeve, the ends of the elastic plates being provided with floats; a reinforcing rod connecting the elastic plates and the sleeve; and an outer frame commonly fitted around the plurality of floats.

[0014] Preferably, a mounting frame is formed at the bottom of the processing chamber; an adjusting plate is provided below the mounting frame, and a mounting lug is fixed on the side of the adjusting plate for threaded connection with a positioning screw, and the mounting frame is locked by the positioning screw; a base plate is provided below the adjusting plate, and the distance between the base plate and the adjusting plate is adjusted by an adjusting screw.

[0015] Preferably, the mounting pipe assembly includes a first flange, an elastic pipe, and a second flange connected in series, wherein the distance between the first flange and the second flange is adjusted by a distance adjustment rod.

[0016] Compared with existing technologies, the present invention provides a sewage treatment device based on urban water network ecosystem restoration, which has the following beneficial effects:

[0017] This invention, by setting up an interception component that cooperates with an inner cylinder and an outer cylinder, and using a control component to drive the outer cylinder to rotate and adjust the overlap between the first through hole and the second through hole section, can dynamically change the interception efficiency according to the influent, thus realizing adaptive control of the sewage treatment process.

[0018] Secondly, the device has a self-cleaning function. During the rotation of the outer cylinder, the cleaning rod extends into the first through hole of the inner cylinder to scrape, which can automatically remove the impurities attached to the first through hole, effectively prevent the first through hole from being blocked, significantly reduce the frequency of manual cleaning and extend the service life of the equipment.

[0019] In addition, the bottom of the treatment chamber is equipped with a non-powered, adaptive flow regulation structure. A float moves a conical sliding rod as the water level rises and falls, automatically adjusting the gap between the sliding rod and the third through-hole of the baffle. This not only achieves an intelligent balance between rapid drainage at high flow rates and delayed drainage at low flow rates, but also physically agitates the wastewater through the undulating float, ensuring thorough mixing of the wastewater and the chemical solution.

Detailed Implementation

[0026] Please refer to Figures 1-5 This invention provides a wastewater treatment device based on urban water network ecosystem restoration, comprising: an inlet pipe 1, one end of which is connected to the urban water network; a treatment chamber 2, connected to the inlet pipe 1, for treating wastewater in the inlet pipe 1, the treatment chamber 2 being equipped with an interception component; an installation pipe assembly 7, disposed below the treatment chamber 2, for adjusting the installation position of the treatment chamber 2; a measuring pipe 8, installed below the installation pipe assembly 7, for draining liquid; a detector 9, disposed on one side of the measuring pipe 8, for detecting the effluent quality of the measuring pipe 8; and a control chamber 4, disposed above the treatment chamber 2, the control chamber 4 also being equipped with a control component, the control component being used to adjust the interception efficiency of the interception component.

[0027] During operation, sewage from the city's water network is first introduced into the treatment chamber 2 through the inlet pipe 1. After entering the treatment chamber 2, the sewage passes through the interception components installed therein. The interception components intercept and pre-treat impurities in the sewage, thereby purifying the sewage. The treated liquid flows downward and passes through the installation pipe assembly 7 installed below the treatment chamber 2. The installation pipe assembly 7 not only serves to connect the liquid but also allows for adjustment of the installation position and height of the treatment chamber 2 according to the actual installation environment requirements.

[0028] The liquid eventually enters the measuring tube 8 for discharge. During this process, the detector 9, located on one side of the measuring tube 8, monitors the quality of the effluent in real time to monitor the treatment effect.

[0029] Meanwhile, the control chamber 4 located above the treatment chamber 2 is equipped with a control component. This control component is connected to the interception component and can adjust the working state of the interception component according to the preset program or the signal fed back by the detector 9, thereby dynamically changing its interception efficiency to adapt to the treatment needs under different water quality conditions.

[0030] The interception assembly includes: an inner cylinder 10, one end of which is connected to the water inlet pipe 1 and the other end is fixed to the inner wall of the treatment chamber 2; an outer cylinder 11, which is rotatably sleeved on the outside of the inner cylinder 10; a plurality of circumferentially distributed support rollers 12, which are rotatably disposed on the inner wall of the treatment chamber 2 and support the outer cylinder 11; the inner cylinder 10 is provided with a plurality of first through holes; and the outer cylinder 11 is provided with second through holes corresponding to the first through holes.

[0031] The control assembly includes: a telescopic rod 5, which is fixed in the control compartment 4; a first connecting rod 51, which is fixed to the telescopic end of the telescopic rod 5; and a second connecting rod 52, which is respectively hinged between the first connecting rod 51 and the outer cylinder 11.

[0032] In other words, sewage enters the treatment chamber 2 through the inlet pipe 1 and flows into the inner cylinder 10. The inner cylinder 10 has multiple first through holes, through which sewage flows outward. The outer cylinder 11 is rotatably sleeved on the outside of the inner cylinder 10, and has corresponding second through holes.

[0033] When it is necessary to adjust the interception efficiency or flow rate, the telescopic rod 5 fixed in the control chamber 4 extends or retracts. Specifically, the telescopic end of the telescopic rod 5 drives the first connecting rod 51 to move. The first connecting rod 51 then drives the outer cylinder 11 to rotate around its axis through the second connecting rod 52. Since the inner cylinder 10 is fixed, the rotation of the outer cylinder 11 changes the relative position between the second through hole on it and the first through hole on the inner cylinder 10, that is, it changes the degree of overlap (misalignment) between the two. When the degree of overlap of the through holes (first through hole and second through hole) is high, the flow area is large and the interception efficiency is low; when the misalignment of the through holes is large, the flow area is small and the interception efficiency is high, thereby realizing the dynamic adjustment of the sewage treatment process. During this process, the circumferentially distributed support rollers 12 are close to the outer wall of the outer cylinder 11 and roll with the rotation of the outer cylinder 11, playing a supporting and guiding role.

[0034] The transmission mechanism, consisting of the telescopic rod 5, the first connecting rod 51, and the second connecting rod 52, smoothly converts linear motion into rotational motion, thereby precisely controlling the rotation angle of the outer cylinder 11. This allows operators to accurately adjust the overlap of the through holes between the inner cylinder 10 and the outer cylinder 11, achieving linear control of the interception efficiency.

[0035] The telescopic rod 5 can be either a hydraulic telescopic cylinder or a pneumatic cylinder.

[0036] Furthermore, a cleaning rod 111 is provided in the second through hole; the cleaning rod 111 extends into the first through hole, and a relief groove 101 corresponding to the cleaning rod 111 is also provided on one side of the first through hole.

[0037] When the outer cylinder 11 rotates relative to the stationary inner cylinder 10, the cleaning rod 111 fixed in the second through hole of the outer cylinder 11 moves in a circular motion around the axis of the inner cylinder 10. When the cleaning rod 111 rotates to the position of the first through hole of the inner cylinder 10, the cleaning rod 111 extends into the first through hole. As the outer cylinder 11 continues to rotate, the cleaning rod 111 generates relative displacement in the first through hole, physically scraping off the attachments on the inner wall and edge of the first through hole. At the same time, since a clearance groove 101 is provided on one side of the first through hole, when the cleaning rod 111 rotates out of the first through hole with the outer cylinder 11, the clearance groove 101 provides clearance space for the cleaning rod 111, avoiding rigid collision or jamming between the cleaning rod 111 and the wall of the first through hole, ensuring smooth rotation.

[0038] It is worth mentioning that the outer cylinder 11 can achieve vibration cleaning of its own second through hole during rotation.

[0039] In this embodiment, a cleaning pipe 6 is provided on the side of the treatment chamber 2 away from the water inlet pipe 1, and the cleaning pipe 6 is used to communicate with the inner cylinder 10.

[0040] During the wastewater treatment process, wastewater enters the treatment chamber 2 through the inlet pipe 1 and first comes into contact with the interception component for filtration. As the operating time progresses, solid impurities and suspended solids trapped by the interception component gradually accumulate inside the inner cylinder 10. When it is necessary to clean these accumulated dirt, the cleaning pipe 6, which is located on the side of the treatment chamber 2 away from the inlet pipe 1, is used. By opening the cleaning pipe 6, the dirt accumulated in the inner cylinder 10 can be discharged directly from the inner cylinder 10 to the outside of the device through the cleaning pipe 6 under the action of water pressure or gravity, thereby completing the cleaning operation inside the interception component.

[0041] In this embodiment, an auxiliary tube 3 is also embedded in the processing chamber 2 for supplying the medicine solution.

[0042] By embedding an auxiliary pipe 3 inside the treatment chamber 2 to supply the chemical solution, a combination of physical interception and chemical treatment is achieved. The chemical solution can specifically kill bacteria in the water and remove dissolved pollutants, significantly improving the treatment effect of wastewater and the quality of effluent.

[0043] In this embodiment, a processing tube is integrally extended from the bottom of the processing chamber 2. A partition 13 is fixed in the processing tube. A plurality of third through holes are opened on the partition 13. A sliding rod 14 is inserted through the third through hole. A float assembly 15 is provided at the top of the sliding rod 14. A stabilizing block 16 and a limiting block 17 are provided at the bottom. A gap is maintained between the sliding rod 14 and the third through hole. The outer diameter of the sliding rod 14 gradually decreases from top to bottom.

[0044] Wastewater is collected in the treatment pipe that extends integrally from the bottom of the treatment chamber 2. As the inflow changes, the water level in the pipe fluctuates. The float assembly 15 floats on the water surface and moves up and down with the rise and fall of the water level, which in turn drives the slide rod 14 to slide vertically in the third through hole fixed on the partition plate 13. During this process, the gap between the slide rod 14 and the third through hole constitutes the main drainage channel. Since the slide rod 14 is tapered, the vertical displacement of the slide rod 14 relative to the third through hole will change the annular water passage area between the two, thereby realizing flow regulation.

[0045] Specifically, when the water volume is large and the water level is high, the float assembly 15 drives the slide rod 14 to float upward, which increases the gap between the slide rod 14 and the third through hole, thereby achieving rapid drainage; when the water volume is small and the water level is low, the float assembly 15 drives the slide rod 14 to move downward, which reduces the gap, thereby slowing down the drainage speed and ensuring processing time.

[0046] Meanwhile, the floating plate assembly 15 moves with the rise and fall of the water level, which continuously agitates the sewage at the bottom of the treatment chamber 2, ensuring that the sewage and the medicine are mixed evenly.

[0047] In addition, the stabilizing block 16 and the limiting block 17 located at the bottom of the slide bar 14 play a guiding and limiting role during the movement.

[0048] The float assembly 15 includes: a sleeve 151, which is fixed to the slide rod 14; a plurality of elastic plates 152 fixed to the sleeve 151, and the ends of the elastic plates 152 are provided with floats 154; a reinforcing rod 153, which connects the elastic plates 152 and the sleeve 151; and an outer frame 155 is commonly fitted around the outside of the plurality of floats 154.

[0049] When the float assembly 15 is in operation, it uses buoyancy to sense changes in water level and drives the slide rod 14 to move up and down. Specifically, multiple floats 154 located at the ends of the elastic sheet 152 are submerged in sewage. As the water level fluctuates, corresponding buoyancy changes occur. This buoyancy is transmitted through the flexible elastic sheet 152 to the sleeve 151 fixed on the slide rod 14, thereby driving the slide rod 14 to slide vertically within the third through hole of the partition 13. During this process, the reinforcing rod 153 connects the elastic sheet 152 and the sleeve 151, providing auxiliary support and reinforcement to prevent excessive twisting of the elastic sheet 152. At the same time, the outer frame 155, which is fitted over the multiple floats 154, provides overall constraint to the floats 154, guiding the entire float assembly 15 to float smoothly with the water level.

[0050] To connect to the urban water network, a mounting frame 21 is formed at the bottom of the treatment chamber 2; an adjustment plate 22 is provided below the mounting frame 21, and a mounting lug 23 is fixed on the side of the adjustment plate 22 for threaded connection of a positioning screw 24, and the mounting frame 21 is locked by the positioning screw 24; a base plate 25 is provided below the adjustment plate 22, and the distance between the base plate 25 and the adjustment plate 22 is adjusted by an adjustment screw 26.

[0051] The mounting pipe assembly 7 includes a first flange 71, an elastic pipe 72, and a second flange 73 connected in series, wherein the distance between the first flange 71 and the second flange 73 is adjusted by a distance adjustment rod 74.

[0052] The installation and connection process of this device consists of two steps: base adjustment and pipeline connection. First, the base plate 25 is placed on the foundation. By rotating the adjusting screw 26, the vertical distance between the adjusting plate 22 and the base plate 25 is changed, thereby coarsely adjusting the height and level of the adjusting plate 22 to adapt to the height of the urban water network interface. After the treatment chamber 2 is placed in place and its bottom mounting bracket 21 is placed on the adjusting plate 22, the positioning screw 24 fixed on the mounting ear 23 is rotated to secure the mounting bracket 21 to the adjusting plate 22 using threaded transmission, thus completing the fixation of the treatment chamber 2.

[0053] Subsequently, the installation pipe assembly 7 is connected below the treatment chamber 2. The installation pipe assembly 7 includes a first flange 71, a flexible pipe 72, and a second flange 73 connected in series. When connecting the outlet of the treatment chamber 2 to the external drainage pipe, if there is an axial dimensional deviation, the relative distance between the first flange 71 and the second flange 73 can be changed by adjusting the distance adjustment rod 74. Due to the flexible pipe 72 (which can be either a rubber corrugated pipe or a high-pressure hose), this assembly can use the expansion or deformation capacity of the flexible pipe 72 to absorb the displacement generated by the adjustment, so that the flanges at both ends can be accurately aligned and tightly fitted, thereby achieving a flexible sealing connection.

[0054] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
