Abstract

This invention discloses a rapid coagulation and settling system for a pre-sedimentation equalization tank, belonging to the field of wastewater treatment technology. It includes an equalization tank body and a dosing assembly. The dosing assembly is located on one side of the equalization tank body, and a buffer mechanism is installed inside the equalization tank body, positioned in the middle of the tank body, and works in conjunction with the dosing assembly. The dosing assembly of this invention relies on a hydraulic linkage transmission structure, enabling adaptive matching of the dosage of chemicals according to the real-time inflow of wastewater. This achieves mechanical follow-up adjustment of flow rate and dosage. The buffer mechanism works in tandem with the inlet pipe to buffer and dissipate energy from the high-speed inflow of wastewater, weakening the impact force of turbulent inflow. It also disperses and agitates the chemicals added into the water, preventing agglomeration and promoting rapid dispersion of chemical particles in the wastewater, increasing the contact reaction area between the chemicals and colloidal and suspended pollutants in the wastewater.

Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically relating to a rapid flocculation and settling system for a pre-sedimentation and equalization tank. Background Technology

[0002] A regulating tank is a structure used to regulate the influent and effluent flow rates. Its main functions are to regulate water quantity and quality, as well as to pre-aerate the wastewater's pH and temperature. Whether it's industrial or municipal wastewater, its quality and quantity constantly change over time, with peak and trough flow rates, as well as peak and trough concentrations. These uneven flow rates and concentrations often pose significant challenges to stable wastewater treatment, preventing the system from operating under optimal conditions and even causing system failure. To improve the operating conditions of the treatment system, it is necessary to regulate the water quantity and quality; the primary method for this is by installing a wastewater regulating tank.

[0003] To further improve wastewater treatment efficiency, accelerate the flocculation and sedimentation rate of suspended impurities and colloidal pollutants in wastewater, and ensure that the effluent quality meets standards, flocculants and regulators are commonly added to the equalization tank in current wastewater treatment processes. Through the coagulation, adsorption, and sedimentation effects of these agents, various pollutants in the wastewater are quickly removed, significantly improving wastewater treatment efficiency and effluent quality.

[0004] However, existing wastewater treatment dosing technologies have significant technical flaws. Currently, most industries adopt a constant flow and constant frequency quantitative dosing mode, which cannot adaptively match and adjust the dosing amount according to the real-time influent flow rate of the equalization tank. When the wastewater influent flow rate is small and the pollutant concentration is low, constant excessive dosing of chemicals will cause serious waste of chemical resources, increase the cost of wastewater treatment chemicals, and at the same time, excessive residual chemicals will remain in the water body, causing secondary water pollution and exacerbating the problems of excessive salinity and chemical residues in the water. When the wastewater influent flow rate is large and the pollutant concentration is high, the fixed dosing amount cannot meet the flocculation and sedimentation requirements, resulting in insufficient dosing of chemicals. The pollutants in the wastewater will not flocculate sufficiently or settle completely. A large amount of suspended impurities and residual pollutants will enter the subsequent treatment units with the water body, which will not only greatly increase the treatment pressure of subsequent processes, but also directly lead to the final effluent quality failing to meet the standards, seriously affecting the treatment quality of the entire wastewater treatment system.

[0005] A search revealed that patent application number 201820587442.4 discloses an equalization tank for a domestic sewage treatment system, including a tank body, an inlet pipe, an outlet pipe, an inlet pump, an outlet pump, and a dosing device installed on the tank body for adding flocculant into the tank. The dosing device includes a support frame, a dosing tank, a dosing assembly, and a driving assembly. The dosing assembly includes a rotating shaft rotatably connected to the bottom of the dosing tank and having a receiving groove for receiving flocculant from the dosing tank, and a power component for driving the rotating shaft to rotate. This invention has the following advantages and effects: by providing a support frame that slides along the length of the tank body, and by installing a dosing tank and a dosing assembly on the support frame, the flocculant in the dosing tank can be evenly added along the length of the tank body as the support frame moves, ultimately improving the uniformity of flocculant dispersion within the tank body.

[0006] Although the above-mentioned device can add the agent into the equalization tank, it still cannot adaptively match and adjust the dosage according to the real-time inflow rate of the equalization tank. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and solve the problem of being unable to adaptively match and adjust the dosage according to the real-time influent flow rate of the equalization tank.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A pre-sedimentation equalization tank rapid coagulation sedimentation system includes an equalization tank body and a dosing component. The dosing component is located on one side of the equalization tank body. A buffer mechanism is installed inside the equalization tank body and is installed in the middle of the equalization tank body. The buffer mechanism cooperates with the dosing component. The dosing component is used to adaptively adjust the dosing amount according to the real-time influent flow rate. The agent is delivered to the inside of the influent pipe and mixed with the sewage under the action of the dosing component. The mixed agent and sewage are directly sprayed onto the buffer mechanism to disperse and collide the agent and sewage for further mixing.

[0009] Furthermore, the dosing assembly includes an inlet pipe, a power chamber, a dosing pipe, a first pulley, a second pulley, and a timing belt. The power chamber is fixedly installed on the inlet pipe. Inside the power chamber, a rotating shaft and blades are arranged.

The dosing roller is fixedly installed on the installation shaft and has several dosing grooves evenly distributed on it. The installation shaft is rotatably installed on the dosing chamber. The second pulley is fixedly installed on the installation shaft and is connected to the first pulley via a timing belt.

[0010] Furthermore, the dosing assembly also includes a pipe rack, which is fixedly installed on the equalization tank body.

[0012] Furthermore, a backstop mechanism is provided on the rotating shaft on one side of the power cavity. The backstop mechanism includes a rotating disk, a fixed ring, and a cover plate. The rotating disk is fixedly installed on the rotating shaft, and the fixed ring is fixedly installed on the outer wall of the power cavity, with the fixed ring and the rotating shaft being concentrically arranged. An installation groove is opened on the inner wall of the fixed ring, and a locking rod and a spring are provided inside the installation groove. One end of the locking rod is rotatably installed on the side wall of the installation groove, and the spring is fixedly installed on the inner wall of the installation groove. The spring is used to provide power for the rotation of the locking rod. A limit block is installed on the outer wall of the rotating disk, and a slope surface is provided on one side of the limit block. The locking rod cooperates with the limit block. The cover plate is fixedly installed on the fixed ring, and the cover plate is located on the outside of the fixed ring.

[0013] Furthermore, it also includes a foot pedal, which is located on the top of the regulating pool body, and guardrails are provided on both sides of the center line of the foot pedal.

[0014] Furthermore, a water filter cylinder and a drain pipe are also provided in the middle of the regulating tank body. The water filter cylinder is fixedly installed at the bottom of the foot pedal, and several filter holes are evenly opened at the bottom of the water filter cylinder. The drain pipe is installed on the regulating tank body, and one end of the drain pipe extends into the interior of the water filter cylinder.

[0015] Furthermore, the buffer mechanism includes a driving component, a stirring shaft, a rotating cylinder, and a connecting rod. The driving component is fixedly mounted on a foot pedal. The stirring shaft is located at the center of the filter cylinder and is rotatably mounted on the bottom wall of the regulating tank body. The driving component provides power for the rotation of the stirring shaft. The middle part of the connecting rod is fixedly mounted on the stirring shaft, and both ends of the connecting rod are fixedly mounted on the inner wall of the rotating cylinder. A buffer plate is provided on the top outer wall of the rotating cylinder. The buffer plate is inclined and there are several buffer plates evenly distributed. A scraper is also provided on the stirring shaft, and the scraper cooperates with the bottom wall of the filter cylinder.

[0016] Furthermore, a rotating ring is provided on the top inner wall of the rotating cylinder, a fixing groove is opened at the bottom of the rotating ring, and several rollers are evenly arranged inside the fixing groove. A support plate is provided on the top outer wall of the filter cylinder, the rollers cooperate with the support plate, and a limit ring is provided on the support plate, the limit ring cooperating with the rotating ring.

[0017] Furthermore, the driving component includes a motor, a bracket, a third pulley, a fourth pulley, and a V-belt. The bracket is fixedly mounted on the pedal, the motor is fixedly mounted on the bracket, the third pulley is fixedly mounted on the output shaft of the motor, and the fourth pulley is fixedly mounted on the stirring shaft. The fourth pulley is connected to the third pulley via the V-belt.

[0018] The beneficial effects of this invention are: (1) The dosing component in this device relies on the hydraulic linkage transmission structure to adaptively match the dosage of the agent according to the real-time inflow of sewage, so as to realize the mechanical follow-up adjustment of the flow rate and the dosage of the agent, and solve the defects of excessive or insufficient dosing of the agent under the traditional fixed dosing mode. The buffer mechanism and the inlet pipe work together to buffer and dissipate the high-speed inflow of sewage and weaken the impact force of the inflow turbulence. On the other hand, it can disperse and disturb the agent added into the water body to avoid the agent from agglomerating and clumping, promote the rapid dispersion of the agent particles in the sewage, and increase the contact reaction area between the agent and colloidal and suspended pollutants in the sewage.

[0019] After the agent and sewage are fully mixed and in contact, the flocculation reaction is more complete and uniform, which can effectively improve the coagulation and sedimentation effect, reduce the phenomenon of local enrichment or lack of agent, and stably ensure the sewage treatment efficiency and effluent quality. At the same time, it reduces problems such as poor sedimentation effect, agent waste, and secondary pollution of water bodies caused by uneven mixing of agents, and improves the adaptability and operational reliability of the entire sewage treatment device under fluctuating water volume and quality conditions.

[0020] (2) In this device, the linkage transmission structure of the rotating shaft, blades, first pulley, second pulley and synchronous belt works together to achieve real-time adaptive adjustment of the dosage based on the sewage inflow. When sewage flows into the device through the inlet pipe, the water flow enters the power chamber and impacts the blades. The fluid kinetic energy of the sewage itself drives the blades to rotate. The blades drive the rotating shaft to rotate synchronously. The rotating shaft further drives the first pulley to rotate. The first pulley transmits the power to the second pulley through the synchronous belt. The second pulley drives the mounting shaft and the dosing roller to rotate together. The dosing roller has a dosing groove on its outer wall. During the rotation of the dosing roller, the agent can be quantitatively delivered through the dosing groove and put into the inlet pipe to complete the dosing. When the inflow increases, the force of the water flow impacting the blades increases and the blade speed increases accordingly. After synchronous transmission through the pulley, the speed of the dosing roller increases synchronously, and the dosage of the agent delivered by the dosing groove per unit time increases accordingly. When the inflow decreases, the driving force of the water flow on the blades decreases, the blade speed decreases, the speed of the dosing roller slows down synchronously, and the dosage of the agent added per unit time decreases accordingly.

[0021] (3) The anti-reverse mechanism in this device is used to prevent the rotating shaft from reversing due to the water inlet during the rotation process. With the cooperation of the locking rod, spring and limit block, it can prevent the rotating disk from reversing. When the blade rotates clockwise along the rotating shaft, the rotating disk rotates clockwise with the blade. Under the action of the spring, the locking rod extending from the mounting groove contacts the inclined surface of the limit block on the rotating disk. Under the action of the inclined surface, one end of the locking rod moves towards the inside of the mounting groove and compresses the spring during this process. After the limit block rotates past, one end of the locking rod extends again under the action of the spring. When the blade drives the rotating shaft to rotate counterclockwise, the rotating disk also rotates counterclockwise with the blade. Then the end of the locking rod hits the end of the limit block, achieving the purpose of limiting the limit block.

[0022] (4) The buffer mechanism in this device can buffer the incoming sewage, prevent the sewage flow rate from being too high, and stir up the sediment at the bottom of the regulating tank, thereby improving the efficiency of sewage treatment. With the coordinated cooperation of the drive unit, stirring shaft, connecting rod and rotating cylinder, the buffer plate can be driven to rotate at a constant speed around the stirring shaft to form a dynamic buffer barrier. After the high-speed sewage comes into contact with the rotating buffer plate, the water flow impact force is effectively decomposed and dissipated, and the turbulent water flow velocity is evenly slowed down, thus completely solving the problem of instantaneous large flow sewage directly hitting the tank. Compared with the traditional fixed buffer structure, the rotating buffer plate can connect to the incoming water flow in all directions without dead angles, with a wider buffer coverage and a more balanced pressure stabilization effect. It can continuously and steadily reduce the turbulent impact force of the incoming sewage, fundamentally avoiding the problem of sediment at the bottom of the tank being stirred up and disturbed by the water flow, ensuring the stability of the sedimentation system in the regulating tank and ensuring that pollutants settle fully.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0037] like Figure 1 , Figure 2 As shown, a pre-sedimentation equalization tank rapid coagulation sedimentation system includes an equalization tank body 1 and a dosing assembly 2. The dosing assembly 2 is located on one side of the equalization tank body 1. A buffer mechanism 6 is installed inside the equalization tank body 1 and is installed in the middle of the equalization tank body 1. The buffer mechanism 6 cooperates with the dosing assembly 2. The dosing assembly 2 is used to adaptively adjust the dosing amount according to the real-time influent flow rate. The chemicals and sewage input from the dosing assembly 2 into the equalization tank body 1 are directly sprayed onto the buffer mechanism 6, and the chemicals and sewage are mixed again by the action of the buffer mechanism 6.

[0038] In this embodiment, as Figure 3 , Figure 4 As shown, the dosing assembly 2 includes an inlet pipe 202, a power chamber 203, a dosing pipe 2010, a first pulley 208, a second pulley 206, and a synchronous belt 205. The power chamber 203 is fixedly installed on the inlet pipe 202. Inside the power chamber 203, a rotating shaft 2013 and blades 2014 are provided. The rotating shaft 2013 is rotatably installed on the side wall of the power chamber 203. The blades 2014 are fixedly installed on the rotating shaft 2013. The blades 2014 are used to provide power for the rotation of the rotating shaft 2013 under the impact of water flow, ensuring that the rotating shaft 2013 can rotate normally.

[0039] The first pulley 208 is located outside the power chamber 203 and is fixedly connected to the rotating shaft 2013. The dosing pipe 2010 is fixedly installed on the water inlet pipe 202. A dosing chamber 209 is provided on the dosing pipe 2010. An installation shaft 2015 and a dosing roller 2016 are provided in the dosing chamber 209. The dosing roller 2016 is fixedly installed on the installation shaft 2015. Several dosing grooves 2017 are evenly opened on the dosing roller 2016. The agent can be quantitatively delivered through the dosing grooves 2017 and put into the water inlet pipe 202 to complete the agent dosing.

[0040] The mounting shaft 2015 is rotatably mounted on the dosing chamber 209, and the second pulley 206 is fixedly mounted on the mounting shaft 2015. The second pulley 206 is connected to the first pulley 208 through the synchronous belt 205.

[0041] Through the coordinated operation of the linkage transmission structure of the rotating shaft 2013, blade 2014, first pulley 208, second pulley 206 and synchronous belt 205, the dosage can be adjusted in real time based on the sewage inflow rate.

[0042] When sewage flows into the device through the inlet pipe 202, the water flow enters the power chamber 203 and impacts the blades 2014. The fluid kinetic energy of the sewage itself drives the blades 2014 to rotate. The blades 2014 drive the rotating shaft 2013 to rotate synchronously. The rotating shaft 2013 further drives the first pulley 208 to rotate. The first pulley 208 transmits power to the second pulley 206 through the synchronous belt 205. The second pulley 206 drives the mounting shaft 2015 and the dosing roller 2016 to rotate together. The dosing roller 2016 has a dosing groove 2017 on its outer wall. During the rotation of the dosing roller 2016, the agent can be quantitatively delivered through the dosing groove 2017 and put into the inlet pipe 202 to complete the agent dosing.

[0043] When the inlet flow rate increases, the force of the water flow impacting the blades 2014 increases, and the rotation speed of the blades 2014 increases accordingly. After synchronous transmission via the pulley, the rotation speed of the dosing roller 2016 increases synchronously, and the dosage of medicine delivered by the dosing tank 2017 per unit time increases accordingly.

[0044] When the inlet flow rate decreases, the driving force of the water flow on the blade 2014 decreases, the rotation speed of the blade 2014 decreases, and the rotation speed of the dosing roller 2016 slows down accordingly, thus reducing the dosage of the drug added per unit time.

[0045] In this embodiment, as Figure 3 As shown, the dosing assembly 2 also includes a pipe frame 201, which is fixedly installed on the regulating tank body 1. The inlet pipe 202 is fixedly installed on the pipe frame 201. An inlet hopper 2012 is provided at one end of the inlet pipe 202, and a connecting flange 2011 is provided at the other end of the inlet pipe 202.

[0046] In this embodiment, as Figure 3 As shown, the dosing assembly 2 also includes a mounting frame 207 and a dosing tank 204. The mounting frame 207 is fixedly installed on the equalization tank body 1, and the dosing tank 204 is fixedly installed on the mounting frame 207. The dosing pipe 2010 is connected to the dosing tank 204. The dosing tank 204 is used to temporarily store the chemicals to ensure that the chemicals can be transported from the dosing pipe 2010 to the inlet pipe 202, so as to realize the normal addition of chemicals in the sewage.

[0047] In this embodiment, as Figure 5 , Figure 6As shown, a backstop mechanism 7 is also provided on the rotating shaft 2013 on one side of the power cavity 203. The backstop mechanism 7 includes a rotating disk, a fixing ring 703 and a cover plate 701. The rotating disk 702 is fixedly installed on the rotating shaft 2013, and the fixing ring 703 is fixedly installed on the outer wall of the power cavity 203. The fixing ring 703 and the rotating shaft 2013 are concentrically arranged. The concentrically arranged fixing ring 703 can constrain the axial and radial positions of the rotating shaft 2013, ensuring that the rotation trajectory of the rotating disk 702 is regular and without deviation.

[0048] Ensure that the locking rod 707 smoothly avoids obstacles when rotating in the forward direction and accurately locks itself when rotating in the reverse direction, ensuring the stable and reliable one-way locking function of the anti-reverse mechanism 7 and avoiding malfunctions such as jamming and limit failure caused by shaft offset.

[0049] An installation groove 706 is provided on the inner wall of the retaining ring 703. The installation groove 706 is used to install the locking rod 707 and the spring 708 to ensure the normal operation of the locking rod 707 and the spring 708.

[0050] Inside the mounting groove 706, there is a locking rod 707 and a spring 708. One end of the locking rod 707 is rotatably mounted on the side wall of the mounting groove 706, and the spring 708 is fixedly mounted on the inner wall of the mounting groove 706. The spring 708 is used to provide power for the rotation of the locking rod 707.

[0051] A limit block 704 is installed on the outer wall of the rotating disk 702. The limit block 704 has a ramp surface 705 on one side. The structural design of the single-sided ramp surface 705 can provide a smooth guiding and avoidance trajectory for the locking rod 707 when the blade 2014 rotates clockwise in the forward direction, ensuring that the locking rod 707 can be smoothly compressed and retracted without interfering with the normal forward transmission operation of the device. This effectively reduces the frictional resistance and mechanical loss of the mechanism and ensures the smooth and stable operation of the hydraulically driven dosing system.

[0052] The locking rod 707 cooperates with the limiting block 704, and the cover plate 701 is fixedly installed on the fixing ring 703, with the cover plate 701 located on the outside of the fixing ring 703.

[0053] The anti-reverse mechanism 7 is used to limit and lock the rotation direction of the rotating shaft 2013 and the blade 2014, effectively solving the technical problem that the blade 2014 is prone to reverse rotation under fluctuating sewage conditions.

[0054] In the actual operation of wastewater treatment, the influent flow rate of the equalization tank is unstable, with fluctuations, instantaneous turbulence, and backflow. This can easily cause the blades 2014 to be impacted by disordered water flow, resulting in reverse rotation, idling, and erratic rotation speed. Consequently, the dosing roller 2016 may be misaligned, the dosing rhythm may be chaotic, and problems such as inaccurate dosing, dosing interruption, and overdosing may occur, severely damaging the dynamic matching accuracy between the influent flow rate and the dosing amount.

[0055] This device, through the precise coordination of the locking rod 707, spring 708 and limit block 704, can achieve one-way self-locking limit of the rotating disk 702, fundamentally eliminating the reverse rotation fault of blade 2014 and rotating shaft 2013, and ensuring the stable and orderly operation of the entire power transmission and dosing system.

[0056] The specific working process is as follows: When the device is working normally, the blade 2014 drives the rotating shaft 2013 to rotate clockwise with the water flow, and the rotating disk 702 rotates clockwise in sync.

[0057] At this time, the end of the locking rod 707 extending out of the mounting groove 706 contacts the inclined surface 705 of the limiting block 704 on the rotating disk 702. Relying on the guiding and squeezing action of the inclined surface 705, the end of the locking rod 707 is pushed back into the mounting groove 706, and the built-in spring 708 is compressed simultaneously, forming an adaptive avoidance structure. This structure will not generate resistance or interference to the forward rotation of the rotating disk 702, ensuring smooth and unobstructed forward transmission of the blade 2014, rotating shaft 2013, pulley and dosing roller 2016, and ensuring that normal adaptive dosing operation is not affected.

[0058] When the limit block 704 rotates completely past the position of the locking rod 707 along with the rotating disk 702, the spring 708 instantly releases its elastic potential energy, pushing the locking rod 707 to quickly extend and reset, always maintaining the ready limit state.

[0059] In this embodiment, as Figure 2 As shown, it also includes a foot pedal 3, which is set on the top of the regulating tank body 1. Guardrails 301 are set on both sides of the center line of the foot pedal 3. The foot pedal 3 is set to facilitate the staff to observe the sewage treatment inside the regulating tank body 1.

[0060] In this embodiment, as Figure 1 , Figure 11 As shown, a filter cylinder 5 and a drain pipe 4 are also provided in the middle of the equalization tank body 1. The filter cylinder 5 is fixedly installed at the bottom of the foot pedal 3. A number of filter holes 501 are evenly opened at the bottom of the filter cylinder 5. The filter holes 501 can filter the sewage inside the equalization tank body 1, and filter out the suspended impurities and flocculated sediments in the sewage, which greatly reduces the processing pressure of subsequent flocculation, sedimentation and filtration processes.

[0061] The drain pipe 4 is installed on the regulating tank body 1, and one end of the drain pipe 4 extends into the interior of the filter cylinder 5. The drain pipe 4 is used to input the filtered sewage into the next process.

[0062] In this embodiment, as Figure 7 , Figure 9 , Figure 10As shown, the buffer mechanism 6 includes a drive component 601, a stirring shaft 6013, a rotating cylinder 602, and a connecting rod 6012. The drive component 601 is fixedly installed on the foot pedal 3. The stirring shaft 6013 is located at the center of the water filter cylinder 5 and is rotatably installed on the bottom wall of the regulating tank body 1. The drive component 601 is used to provide power for the rotation of the stirring shaft 6013.

[0063] The middle part of the connecting rod 6012 is fixedly installed on the stirring shaft 6013, and the two ends of the connecting rod 6012 are fixedly installed on the inner wall of the rotating cylinder 602. A buffer plate 603 is provided on the top outer wall of the rotating cylinder 602. The buffer plate 603 is inclined and there are several buffer plates 603 evenly arranged.

[0064] A scraper 6011 is also provided on the stirring shaft 6013. The scraper 6011 cooperates with the bottom wall of the filter cylinder 5. The scraper 6011 can remove the impurities or flocculated sediments that are blocked in the filter holes 501 and adsorbed at the bottom of the filter cylinder, ensuring the normal operation of the filter cylinder and the normal discharge of sewage.

[0065] The buffer mechanism 6 addresses the pain points of excessively fast instantaneous flow velocity and strong water flow impact in the equalization tank by achieving flexible buffering and pressure stabilization of the influent, effectively optimizing the sewage treatment environment inside the equalization tank.

[0066] In actual wastewater treatment operations, the influent flow rate of wastewater fluctuates greatly. When wastewater with a high instantaneous flow rate rushes into the tank, it will create a strong water flow impact on the bottom of the equalization tank. This will easily stir up and agitate the sediment, suspended impurities, and flocculated sediments deposited at the bottom of the tank. As a result, the pollutants that have been settled will be resuspended in the water, causing the turbidity of the wastewater to rise again. This will significantly increase the treatment pressure of subsequent flocculation, sedimentation, and filtration processes, and directly reduce the wastewater treatment efficiency and the stability of the effluent quality.

[0067] This mechanism, through the coordinated linkage of the drive component 601, the stirring shaft 6013, the connecting rod 6012 and the rotating cylinder 602, can drive the buffer plate 603 to rotate at a constant speed around the stirring shaft 6013, forming a dynamic buffer barrier.

[0068] When the high-speed sewage flows into the buffer plate 603 in contact with the rotating buffer plate, the impact force of the water flow is effectively decomposed and dissipated, and the turbulent water flow velocity is evenly slowed down, thus completely solving the problem of instantaneous large-volume sewage directly rushing into the pool.

[0069] Compared to traditional fixed buffer structures, the rotating buffer plate 603 can connect to the incoming water flow in all directions without dead angles, with a wider buffer coverage and a more balanced pressure stabilization effect. It can continuously and steadily reduce the turbulent impact force of the incoming sewage, fundamentally avoiding the problem of sediment at the bottom of the pool being stirred up and disturbed by the water flow, ensuring the stability of the sedimentation system in the pool, and ensuring that pollutants settle fully.

[0070] Meanwhile, the working mode of the buffer plate 603 rotating synchronously with the structure can play an auxiliary role in disturbing and homogenizing the sewage in the pool, making the water quality and concentration distribution more uniform, helping to improve the mixing reaction effect of the agent and sewage, further improving the flocculation and sedimentation efficiency, effectively avoiding problems such as substandard sewage treatment and repeated processing caused by secondary suspension of sediment, significantly improving the operating efficiency and stability of the entire sewage treatment system, and reducing sewage treatment energy consumption and operation and maintenance costs.

[0071] In this embodiment, as Figure 8 , Figure 11 As shown, a rotating ring 604 is provided on the top inner wall of the rotating cylinder 602, and a fixing groove 605 is opened at the bottom of the rotating ring 604. Several rollers 606 are evenly arranged inside the fixing groove 605. A support plate 502 is provided on the top outer wall of the filter cylinder 5. The rollers 606 cooperate with the support plate 502. The setting of the rollers 606 can reduce the friction between the support plate 502 and the rotating ring 604, ensuring the normal operation of the rotating cylinder 602.

[0072] A limiting ring 503 is provided on the support plate 502. The limiting ring 503 cooperates with the rotating ring 604. The limiting ring 503 is used to limit the rotating ring 604 to prevent the rotating ring 604 from shifting on the support plate 502 during operation, thus ensuring the normal operation of the rotating cylinder 602.

[0073] In this embodiment, as Figure 9 As shown, the drive unit 601 includes a motor 608, a bracket 607, a third pulley 6010, a fourth pulley 6014, and a V-belt 609. The bracket 607 is fixedly mounted on the foot pedal 3, the motor 608 is fixedly mounted on the bracket 607, the third pulley 6010 is fixedly mounted on the output shaft of the motor 608, and the fourth pulley 6014 is fixedly mounted on the stirring shaft 6013. The fourth pulley 6014 is connected to the third pulley 6010 through the V-belt 609.

[0074] The electric motor 608 drives the third pulley 6010 to rotate, and the third pulley 6010 drives the fourth pulley 6014 to rotate through the V-belt 609. The rotation of the fourth pulley 6014 drives the stirring shaft 6013 to rotate, and the rotation of the stirring shaft 6013 will drive the rotating cylinder 602 and the buffer plate 603 to rotate.

[0075] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of the present invention, they should all fall within the protection scope of the present invention.
