Description

Technical Field

[0001] This invention relates to the field of water pollution treatment technology, specifically to an integrated machine for deep treatment of wastewater by flocculation sedimentation and membrane separation. Background Technology

[0002] Integrated wastewater treatment equipment is widely used in the field of deep treatment of small and medium-sized industrial wastewater and municipal sewage due to its high integration, compact footprint, and low infrastructure investment. The integrated wastewater flocculation sedimentation and membrane separation deep treatment machine is a typical integrated equipment that integrates flocculation reaction, solid-liquid sedimentation, and membrane deep treatment units. It does not require separate structures or intermediate buffer tanks and can complete one-stop purification of sewage. Existing similar integrated machines usually form a flocculation chamber and a separation chamber inside the box by separating them with an overflow plate. The flocculation chamber is equipped with a fixed-angle inclined plate to complete the solid-liquid separation of flocs. The water after sedimentation overflows into the separation chamber and is deeply filtered by the membrane separation treatment component to ensure the quality of the effluent.

[0003] In actual operation, the integrated wastewater treatment equipment shortens the floc settling path and improves sedimentation efficiency through multiple sets of inclined plates inside the flocculation chamber. However, the length and inclination angle of the inclined plates are relatively fixed during use. The water flow velocity between the plates changes with the inlet pressure and flow rate. When the inlet pressure increases and the flow velocity between the plates increases, the floc settling time is insufficient, and small, broken flocs easily penetrate the sedimentation channels formed by the inclined plates and flow with the water through the overflow plate into the membrane separation chamber (see instruction manual appendix). Figure 15 (Illustrative image) Tiny flocs continuously adhere to the surface of the membrane module, forming a dense sludge cake layer, which affects subsequent membrane separation and deep treatment operations; To address the issue of floc escape caused by flow fluctuations, some separate water treatment processes add a buffer tank between the sedimentation tank and the membrane treatment unit. The buffer tank absorbs water flow disturbances, reduces water flow velocity, and intercepts escaped flocs. However, the buffer tank occupies a large area, which violates the original design intention of compact integration of integrated equipment and cannot be adapted to the transformation of integrated equipment. Therefore, we propose an integrated machine for deep treatment of wastewater flocculation sedimentation and membrane separation. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated machine for deep treatment of wastewater by flocculation sedimentation and membrane separation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated machine for wastewater flocculation sedimentation and membrane separation deep treatment, comprising a treatment tank for wastewater treatment, wherein the treatment tank is provided with an inlet and an outlet, an overflow plate is fixed inside the treatment tank, and the interior of the treatment tank is divided by the overflow plate to form a flocculation chamber and a separation chamber, the inlet communicating with the flocculation chamber, the outlet communicating with the separation chamber, and a membrane separation treatment component for membrane separation deep treatment being provided inside the separation chamber, further comprising: A sedimentation auxiliary component is installed inside the flocculation chamber of the treatment box to help reduce the sedimentation path of flocs. The sedimentation auxiliary component includes multiple sets of inclined plates evenly distributed in a horizontal state inside the flocculation chamber. The inclined plates are set in an inclined state, and the inclined plates are provided with adjustment components for adjusting the length of the inclined plates. A drive assembly, mounted on the treatment chamber, is used to adjust the tilt angle of the inclined plate. The flocculation chamber contains a transmission assembly for driving the adjustment assembly during the tilting process of the inclined plate. The flocculation chamber also contains an identification assembly for recognizing wastewater transport pressure. A linkage assembly is provided between the identification assembly and the drive assembly for auxiliary linkage. Through the cooperation of the identification assembly, linkage assembly, and drive assembly, the tilt angle of the inclined plate is reduced after the wastewater transport pressure at the inlet increases. Furthermore, during the adjustment of the inclined plate tilt angle, the transmission assembly increases the transport path between adjacent sets of inclined plates, reducing the probability of particle escape during flocculation and sedimentation. And a sludge discharge assembly installed on the treatment tank for discharging and transporting sludge after sedimentation.

[0006] Preferably, the sedimentation auxiliary component further includes an installation shaft fixed to the end of the inclined plate. The installation shaft is rotatably connected to the inside of the flocculation chamber. The two sets of inclined plates on the outermost sides of the flocculation chamber are flexibly connected to the inner wall of the flocculation chamber through flexible baffles. A channel for transporting wastewater after flocculation treatment is formed between two adjacent sets of inclined plates. During the transport of wastewater in the channel, the particles generated by flocculation adhere to the surface of the inclined plates, assisting in flocculation and sedimentation.

[0007] Preferably, the inclined plate is provided with sealing gaskets on both sides for sealing against the inner wall of the flocculation chamber.

[0008] Preferably, the drive assembly includes a mounting slot on one side of the processing box, one end of the mounting shaft is located inside the mounting slot and a driven worm gear is fixed thereon, a mounting bracket is fixed inside the mounting slot, a drive shaft is rotatably connected to the mounting bracket, a plurality of driven worm gears are fixed on the drive shaft, each set of driven worm gears is respectively meshed with each set of driven worm gears, and a cover plate is detachably installed on the mounting slot.

[0009] Preferably, the identification component includes a connecting shaft rotatably connected inside the flocculation chamber. An identification plate for sealing against the inside of the inlet is fixed on the connecting shaft. A torque component for torque connection of the connecting shaft is provided on the connecting shaft. Through the torque component, the identification plate is sealed against the inside of the inlet. When wastewater is transported at the inlet, the connecting shaft rotates due to the action of the water against the identification plate. The amplitude of rotation increases synchronously with the increase of wastewater transport pressure.

[0010] Preferably, the linkage component includes a drive worm gear disposed inside the mounting groove, one end of the connecting shaft is located inside the mounting groove and fixed to the drive worm gear, and a drive worm wheel is fixed on the drive shaft, with the drive worm gear and the drive worm wheel meshing with each other.

[0011] Preferably, the torque assembly includes a retaining ring fixed to the connecting shaft, an mounting ring is fixedly connected to the inner wall of the mounting groove by means of threads, a torsion spring is connected between the retaining ring and the mounting ring, and the torsion spring is sleeved on the outside of the connecting shaft.

[0012] Preferably, the adjustment component includes a groove formed at the end of the inclined plate away from the mounting shaft, and an extension plate is slidably connected to the groove, the extension plate being set at the same inclination angle as the inclined plate.

[0013] Preferably, two sets of transmission components are symmetrically arranged on both sides of the extension plate. The transmission components include transverse grooves opened on the inner wall of the flocculation chamber. A pin is rotatably connected to one side of the extension plate. One end of the pin is located inside the transverse groove and connected to a slider. The slider is slidably connected inside the transverse groove. A flexible strip for assisting flexible sealing connection is provided between the pin and the inner wall of the transverse groove.

[0014] Preferably, the sludge discharge assembly includes multiple sets of V-shaped collection troughs for sludge collection located at the bottom of the flocculation chamber. Particles collected on the inclined plate sink under the action of gravity and accumulate on the V-shaped collection troughs to form sludge. A sludge discharge pipe is installed on the treatment box, one end of which is connected to the V-shaped collection trough. A control valve for sludge discharge control is installed on the sludge discharge pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention abandons the passive sedimentation structure of traditional integrated machines with fixed tilt angles and lengths of inclined plates. Through the mechanical linkage of identification components, linkage components, drive components, transmission components, and adjustment components, the working state of the inclined plate can be adaptively adjusted according to the real-time wastewater delivery pressure at the inlet. When the inlet water pressure increases, the inlet flow rate surges, or the water flow velocity between the plates increases instantaneously, the equipment can automatically reduce the tilt angle of the inclined plate and simultaneously extend the extension plate to increase the effective length of the inclined plate. This significantly increases the horizontal projection sedimentation area of ​​the inclined plate, prolongs the floc settling time, effectively counteracts the particle dragging effect caused by high flow velocity, changes the floc movement trajectory, and prevents small broken flocs from penetrating the sedimentation channel and entering the membrane separation chamber.

[0016] 2. This invention has the capability of adaptive reset adjustment under working conditions, which can adapt to the alternating high and low load operation of the equipment. When the inlet water pressure drops and the equipment returns to the normal low flow operation state, the mechanism can automatically reset by relying on the torsion spring torque, and simultaneously increase the tilt angle of the inclined plate and shorten the extension length of the inclined plate. Increasing the tilt angle of the inclined plate can increase the downward force of the sludge's own weight, ensuring that the sludge deposited on the plate surface slides off quickly. Shortening the effective length of the inclined plate can reduce the sludge attachment and bearing area, avoiding the problem of long-term static sludge and sludge stagnation under low flow rate and low disturbance conditions. It effectively prevents secondary faults such as sludge accumulation and blockage in the inclined plate channel, local flow deviation, and abnormal increase in local flow velocity, and ensures the long-term continuous and stable operation of the flocculation and sedimentation unit. 3. This invention adopts a worm gear meshing transmission structure, which has unidirectional transmission and mechanical self-locking characteristics. It can only drive the mechanism to adjust in the forward direction by changes in inlet water pressure. Water turbulence, water flow impact, and equipment vibration cannot drive the inclined plate to shift in the reverse direction. After the inlet water pressure stabilizes, the mechanism immediately locks and positions itself, ensuring that the inclination angle and extension length of the inclined plate always maintain the optimal working state. This eliminates fluctuations in the sedimentation effect caused by the swaying of the inclined plate and the angle shift. At the same time, it is combined with a multi-flexible sealing structure of sealing gaskets on both sides of the inclined plate, flexible side baffles, and flexible transverse grooves to completely seal the gaps in the tank wall and the moving transmission gaps, eliminating water flow short circuits, flow deviations, and local eddy disturbances, and ensuring a uniform and stable sedimentation flow field. 4. This equipment relies on the principle of inclined plate shallow pool sedimentation, which greatly shortens the floc settling path. Without increasing the equipment box footprint or adding an external buffer pool, it significantly improves the internal sedimentation efficiency of the integrated machine. It retains the core advantages of integrated equipment, such as small footprint, high integration, and low infrastructure cost. At the same time, through the linkage and adaptive adjustment of the inclination angle and length, it dynamically matches the real-time influent load. It does not sacrifice the equipment's processing throughput to achieve sedimentation effect, so that high flow and high load do not reduce water quality and low flow and low load do not clog the channel. It effectively improves the adaptability of the whole machine and the overall stability of sewage treatment. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of 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.

[0020] Example 1

[0021] Please see Figures 1-15 The figure shows an integrated wastewater flocculation sedimentation and membrane separation deep treatment machine, including a treatment tank 101 for wastewater treatment. The treatment tank 101 is provided with an inlet 102 and an outlet 103. An overflow plate 104 is fixed inside the treatment tank 101, and the inside of the treatment tank 101 is divided by the overflow plate 104 to form a flocculation chamber and a separation chamber. The inlet 102 is connected to the flocculation chamber, and the outlet 103 is connected to the separation chamber. The separation chamber is provided with a membrane separation treatment component 105 for membrane separation deep treatment. It should be noted here that the wastewater transportation, flocculation treatment and separation treatment on the treatment tank 101 are known technologies in the technical field of this application, and the specific steps and operation methods are not described in detail here. Also includes: A sedimentation auxiliary component is installed inside the flocculation chamber of the treatment box 101 to help reduce the sedimentation path of the flocs. The sedimentation auxiliary component includes multiple sets of inclined plates 202 that are evenly distributed in a horizontal state inside the flocculation chamber. The inclined plates 202 are set in an inclined state, and an adjustment component for adjusting the length of the inclined plates 202 is provided on the inclined plates 202. A drive assembly, mounted on the treatment tank 101, is used to drive the tilt angle of the inclined plate 202. The flocculation chamber is equipped with a transmission assembly for driving the adjustment assembly during the tilting process of the inclined plate 202. The flocculation chamber of the treatment tank 101 is equipped with an identification assembly for identifying the wastewater delivery pressure. A linkage assembly for auxiliary linkage is set between the identification assembly and the drive assembly. Through the cooperation of the identification assembly, linkage assembly and drive assembly, the tilt angle of the inclined plate 202 is reduced after the wastewater delivery pressure at the inlet 102 increases. During the adjustment of the tilt angle of the inclined plate 202, the transmission assembly increases the conveying path between two adjacent sets of inclined plates 202, reducing the probability of particle escape during the flocculation and sedimentation process. And a sludge discharge assembly installed on the treatment tank 101 for discharging and transporting sludge after sedimentation; It should be noted that through the cooperation of the sedimentation auxiliary components, adjustment components, drive components, identification components, transmission components and linkage components, the inclined plate 202 can adaptively adjust its tilt angle and extension length according to the changes in inlet water pressure during the sedimentation process. This reduces the penetration of fine broken floc particles into the separation chamber through the sedimentation channel, while facilitating the smoother and faster downward flow and collection of sludge accumulated on the surface of the inclined plate 202 by its own weight, preventing sludge from being retained between the plates for a long time and causing blockage of the plate channel.

[0022] Preferably, the sedimentation auxiliary component also includes a mounting shaft 201 fixed to the end of the inclined plate 202. The mounting shaft 201 is rotatably connected to the inside of the flocculation chamber. The two sets of inclined plates 202 at the outermost sides of the flocculation chamber are flexibly connected to the inner wall of the flocculation chamber through flexible baffles 203. A channel for conveying wastewater after flocculation is formed between the two adjacent sets of inclined plates 202. During the process of conveying wastewater in the channel, the particles generated by flocculation adhere to the surface of the inclined plate 202, which assists in flocculation and sedimentation. It should be noted that: the wastewater to be treated is continuously fed into the flocculation chamber of the treatment tank 101 through the inlet 102. In the flocculation chamber, the wastewater completes the mixing of reagents and flocculation reaction, and alum flocs are formed inside the water. Then, the wastewater carrying the flocs flows upward through the sedimentation channel composed of multiple sets of inclined plates 202. Shallow sedimentation is achieved by relying on the inclined plates 202. The alum flocs adhere to and settle on the surface of the inclined plates 202. The flocs accumulated on the plate surface slide down by their own weight and fall into the V-shaped collection tank 901 at the bottom of the flocculation chamber for collection and storage. The upper clear water after flocculation and sedimentation passes over the overflow plate 104 and flows into the separation chamber. Then, the membrane separation treatment component 105 inside the separation chamber performs membrane separation deep filtration on the water, intercepting residual small impurities in the water. Finally, the deeply purified water is discharged from the outlet 103, completing the entire wastewater treatment process. In addition, the specific working methods and operating principles of wastewater treatment, including reagent mixing, flocculation reaction and subsequent membrane separation and deep filtration, are well-known technologies and will not be elaborated on here.

[0023] Preferably, the inclined plate 202 is provided with sealing gaskets on both sides for sealing against the inner wall of the flocculation chamber; It should be noted here that the sealing gasket reduces the chance of particles in the wastewater escaping upwards through the gap between the inclined plate 202 and the inner wall of the flocculation chamber.

[0024] Preferably, the drive assembly includes a mounting groove 301 formed on one side of the treatment tank 101, one end of a mounting shaft 201 located inside the mounting groove 301 and fixed with a driven worm gear 302, a mounting bracket 303 fixed inside the mounting groove 301, a drive shaft 304 rotatably connected to the mounting bracket 303, and multiple sets of driven worm gears 305 fixed on the drive shaft 304, each set of driven worm gears 305 meshing with each set of driven worm gears 302 respectively, and a cover plate 306 detachably mounted on the mounting groove 301; the identification assembly includes a connecting shaft 401 rotatably connected inside the flocculation chamber, an identification plate 402 fixed on the connecting shaft 401 for sealing against the inside of the inlet 102, and a connecting... A torque assembly is provided on shaft 401 for torque connection of connecting shaft 401. Through the torque assembly, the identification plate 402 is blocked against the inner side of the inlet 102. When wastewater is transported at the inlet 102, the connecting shaft 401 is rotated by the action of water against the identification plate 402. The rotation amplitude increases synchronously with the increase of wastewater transport pressure. The linkage assembly includes an active worm gear 501 disposed inside the mounting groove 301. One end of the connecting shaft 401 is located inside the mounting groove 301 and fixed to the active worm gear 501. The active worm gear 502 is fixed on the drive shaft 304, and the active worm gear 501 and the active worm gear 502 are meshed with each other. It should be noted here that during the wastewater transportation and treatment process, the water flow entering through the inlet 102 continuously impacts the identification plate 402. The identification plate 402 overcomes the torque provided by the torsion spring 603, causing the connecting shaft 401 to rotate. The active worm 501 fixed at the end of the connecting shaft 401 rotates synchronously. The active worm 501 meshes with the active worm wheel 502, and the active worm wheel 502 rotates accordingly, synchronously driving the drive shaft 304 to rotate. Multiple sets of driven worms 305 are fixed on the drive shaft 304. The driven worms 305 rotate synchronously and mesh with each set of driven worm wheels 302 respectively. The driven worm wheels 302 drive the corresponding mounting shaft 201 to rotate synchronously. The mounting shaft 201 drives the inclined plate 202 to rotate, thereby reducing the tilt angle of the inclined plate 202. In addition, during the entire transmission process, the entire transmission relies on the meshing transmission of worm gears. The worm gears have unidirectional transmission and mechanical self-locking characteristics. When the inlet water pressure is stable, the worm gears lock and position themselves, and the inclined plate 202 maintains the adjusted inclination angle and unfolded length. It will not be affected by water disturbance and will not deviate in angle, thus ensuring the stable operation of sedimentation.

[0025] Preferably, the torque assembly includes a retaining ring 601 fixed to the connecting shaft 401, an mounting ring 602 fixedly connected to the inner wall of the mounting groove 301 by means of threads, a torsion spring 603 connected between the retaining ring 601 and the mounting ring 602, and the torsion spring 603 sleeved on the outer side of the connecting shaft 401. It should be noted here that the connecting ring 601 and the torsion spring 603 between the retaining ring 601 and the mounting ring 602 facilitate the generation of torque on the connecting shaft 401, which helps to reset the connecting shaft 401 after rotation.

[0026] Preferably, the adjustment assembly includes a groove 701 formed at the end of the inclined plate 202 away from the mounting shaft 201, an extension plate 702 is slidably connected to the groove 701, and the extension plate 702 is set at the same inclination angle as the inclined plate 202; two sets of transmission assemblies are symmetrically arranged on both sides of the extension plate 702, and the transmission assembly includes a transverse groove 801 formed on the inner wall of the flocculation chamber, a pin 802 is rotatably connected to one side of the extension plate 702, one end of the pin 802 is located inside the transverse groove 801 and connected to a slider 803, the slider 803 is slidably connected inside the transverse groove 801, and a flexible strip 804 for assisting flexible sealing connection is provided between the pin 802 and the inner wall of the transverse groove 801; It should be noted that as the inclined plate 202 rotates downward around the mounting shaft 201 and the inclination angle decreases, it drives the extension plate 702 to rotate synchronously. During the rotation of the extension plate 702, the pin 802 at the end of the extension plate 702 drives the slider 803 to slide along the transverse groove 801 on the inner wall of the flocculation chamber. During the sliding process, the extension plate 702 slides outward along the sliding groove 701 opened on the inclined plate 202, thereby increasing the effective length of the inclined plate 202 synchronously and lengthening the wastewater transport path between adjacent inclined plates 202 synchronously. In addition, by setting the flexible belt 804, the interior of the transverse groove 801 is sealed and the pin 802 is flexibly connected to prevent foreign objects from entering the interior of the transverse groove 801 and affecting the transmission.

[0027] Preferably, the sludge discharge assembly includes multiple sets of V-shaped collection troughs 901 for sludge collection located at the bottom of the flocculation chamber. The particles collected on the inclined plate 202 sink under the action of gravity and accumulate on the V-shaped collection troughs 901 to form sludge. A sludge discharge pipe 902 is installed on the treatment box 101. One end of the sludge discharge pipe 902 is connected to the V-shaped collection troughs 901. A control valve 903 for sludge discharge control is installed on the sludge discharge pipe 902. It should be noted here that: the flocs adhere to and settle on the surface of the inclined plate 202. The flocs accumulated on the plate surface slide down by their own weight and fall into the V-shaped collection trough 901 at the bottom of the flocculation chamber for collection and storage. The sludge accumulated in the V-shaped collection trough 901 at the bottom of the flocculation chamber can be discharged outward through the sludge discharge pipe 902 by opening the control valve 903 at regular intervals. Furthermore, the control and methods for the discharge of collected sludge are known technologies in this application and will not be elaborated upon here.

[0028] This solution describes an integrated machine for deep treatment of wastewater through flocculation sedimentation and membrane separation, comprising the following steps: The wastewater to be treated is continuously fed into the flocculation chamber of the treatment tank 101 through the inlet 102. In the flocculation chamber, the wastewater undergoes reagent mixing and flocculation reaction, forming flocculent material. Then, the wastewater carrying the flocculent material flows upward through a sedimentation channel composed of multiple inclined plates 202, achieving shallow sedimentation. The flocculent material adheres to and settles on the surface of the inclined plates 202. The accumulated flocculent material slides down by its own weight and falls into the V-shaped collection tank 901 at the bottom of the flocculation chamber for collection and storage. The clear water after flocculation and sedimentation flows over the overflow plate 104 into the separation chamber. Next, the membrane separation unit 105 inside the separation chamber performs deep filtration, trapping residual micro-impurities. Finally, the deeply purified water is discharged from the outlet 103, completing the entire wastewater treatment process (see [reference]). Figure 12 and Figure 13 The sludge accumulated in the V-shaped collection trough 901 at the bottom of the flocculation chamber can be discharged outward through the sludge discharge pipe 902 by opening the control valve 903 at regular intervals. During wastewater transportation and treatment, the water flow entering through inlet 102 continuously impacts the identification plate 402. The identification plate 402 overcomes the torque provided by the torsion spring 603, causing the connecting shaft 401 to rotate. The active worm 501 fixed at the end of the connecting shaft 401 rotates synchronously. The active worm 501 meshes with the active worm wheel 502, causing the active worm wheel 502 to rotate accordingly, synchronously driving the drive shaft 304 to rotate. Multiple sets of driven worms 305 are fixed on the drive shaft 304. The driven worms 305 rotate synchronously and mesh with each set of driven worm wheels 302 respectively. The driven worm wheels 302 drive the corresponding mounting shaft 201 to rotate synchronously. The mounting shaft 201 drives the inclined plate 202 to rotate, thereby reducing the tilt angle of the inclined plate 202. Furthermore, during the entire transmission process, when the inlet water pressure increases, the amplitude of the rotation of the identification plate 402 increases, which, in conjunction with subsequent transmission, further reduces the tilt angle of the inclined plate 202 (see...). Figure 14 The inclined plate 202's tilt angle decreases as the inlet water pressure increases. Furthermore, as the inclined plate 202 rotates downwards around the mounting shaft 201 and its tilt angle decreases, it drives the extension plate 702 to rotate synchronously. During this rotation, the pin 802 at the end of the extension plate 702 drives the slider 803 to slide along the transverse groove 801 on the inner wall of the flocculation chamber. During this sliding process, the extension plate 702 slides outwards along the sliding groove 701 on the inclined plate 202, thus simultaneously increasing the effective length of the inclined plate 202 and lengthening the wastewater transport path between adjacent inclined plates 202 (see [reference]). Figure 14 (in the state of the inclined plate 202), the sealing gaskets on both sides of the inclined plate 202, the side flexible baffle 203, and the flexible strip 804 at the pin 802 continuously maintain the cavity seal to prevent water from flowing through and short-circuiting. As the inlet pressure of the wastewater increases, the inclination angle of the inclined plate 202 decreases and the effective length of the inclined plate 202 increases, thereby increasing the overall horizontal projection sedimentation area of ​​the inclined plate 202 (see...). Figure 14 (Illustration) The floc settling residence time is extended, which offsets the increase in interplate flow velocity caused by the increase in inlet water pressure, reduces the penetration of small broken flocs into the separation chamber through the sedimentation channel, and avoids irreversible membrane fouling caused by dense mud cake and PAM adsorption in the membrane separation treatment component 105. In the entire transmission process, the entire transmission relies on the meshing transmission of worm gears. The worm gears have unidirectional transmission and mechanical self-locking characteristics. When the inlet water pressure is stable, the worm gears lock and position each other, and the inclined plate 202 maintains the adjusted inclination angle and unfolded length. It will not be affected by water disturbance and will not deviate in angle, ensuring stable operation of sedimentation. When the wastewater conveying pressure at the inlet 102 decreases, the impact force of the water flow on the identification plate 402 decreases. Under the reset torque of the torsion spring 603, the connecting shaft 401 rotates in the opposite direction. During the reverse rotation of the connecting shaft 401, the opposite rotation causes the inclined plate 202 to increase its tilt angle and reduce its extension length. After reset, the inclined plate 202 maintains a suitable steepness in conjunction with the reduction in extension length, which facilitates the sludge accumulated on the surface of the inclined plate 202 to slide more smoothly and quickly to the bottom V-shaped collection trough 901 by its own weight, preventing the sludge from being stuck between the plates for a long time and causing blockage of the plate channel.
