Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a multi-stage rectifier adaptive sedimentation treatment device for wastewater. Background Technology

[0002] In wastewater treatment engineering, sedimentation separation is the core process for removing suspended solids and colloidal impurities from water, and its operational efficiency directly affects the load of subsequent advanced treatment units and the final effluent quality.

[0003] Existing sedimentation treatment systems mostly adopt a split layout, where the reaction tank, flocculation tank, and sedimentation tank are independent and connected by pipes or channels. This layout not only occupies a large area, increasing the investment cost of civil engineering and piping, but more importantly, the connecting pipes between units are prone to head loss and water flow turbulence, resulting in uneven water flow distribution into the sedimentation tank, short-circuiting, and dead water zones. This significantly reduces the effective volume utilization rate of the sedimentation tank and affects the overall treatment effect. After long-term operation, a large amount of concentrated sludge accumulates at the bottom of the sedimentation tank. If sludge removal is not timely or thorough, it will float to the surface due to anaerobic fermentation, affecting the effluent quality. Existing sludge removal equipment often only effectively cleans the central area of ​​the tank bottom, making it difficult to reach the four corners of the sedimentation tank and the sludge adhering to the tank wall surface. These corner dead zones and tank wall sludge, if left to stagnate for a long time, will gradually harden and compact, not only reducing the effective sedimentation volume but also increasing the difficulty of subsequent cleaning. In severe cases, it may require shutdown for manual cleaning, greatly increasing operation and maintenance costs and workload. In addition, although some improved devices are equipped with sludge scrapers, their scraper blades are usually of a fixed radial length and cannot adaptively conform to the shape of the pool wall at different locations. For sedimentation tanks with curved walls or irregular structures, the scraping effect is even worse.

[0004] Therefore, how to provide a multi-stage rectified adaptive sedimentation treatment device for wastewater to solve the defects of existing sewage sedimentation treatment structures is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address this issue, the present invention provides a multi-stage rectifier adaptive sedimentation treatment device for wastewater, which solves the problem of poor sludge removal effect caused by the inability of the sludge scraping mechanism to actively adjust in the prior art.

[0012] In one possible implementation, the scraping actuation component includes: The mounting plate has an internal mounting groove. The mounting plate is installed on the top of the first sedimentation tank or the second sedimentation tank. A drive motor is installed on the top of the mounting plate. A first gear and a second gear are installed in the mounting groove. The first gear and the second gear mesh. The first gear is installed at the bottom output end of the drive motor. A limit sleeve is installed at the bottom of the mounting plate. The bushing is installed at the bottom of the frustum-shaped storage slot; The rotating shaft is mounted at the top in the second gear, and at the bottom, it passes through the bottom plate of the mounting plate and the limiting sleeve and is inserted into the bushing. Several trapezoidal plates are installed on the bottom periphery of the rotating shaft, and the trapezoidal plates are disposed in the frustum-shaped storage groove; An annular sleeve is installed on the rotating shaft. The annular sleeve is positioned above the trapezoidal plate. Several sleeves are provided on the outer periphery of the annular sleeve, and an annular scraper is installed at the bottom of the sleeve. An I-shaped slide rod is slidably connected in the sleeve. A connecting rod is installed at the outer end of the I-shaped slide rod, and a first scraper is installed at the outer end of the connecting rod. The first scraper has arc-shaped surfaces at both ends.

The linkage component is connected at its upper end to the I-shaped slide bar, and a second scraper is connected at the bottom of the linkage component.

[0013] In one possible implementation, the linkage component includes: T-shaped connecting cylinders are arranged in pairs, with their tops mounted on the inner wall of the top of the sleeve.

This reduces land occupation, lowers costs, and minimizes short-circuiting and stagnant water zones. By setting up two identical, series-connected reaction-flocculation-sedimentation units (first and second stages), wastewater undergoes two sequential mixing, flocculation, and sedimentation processes, achieving deep wastewater treatment. This effectively removes suspended solids and colloidal impurities, significantly improving effluent quality. A scraper is installed in the sedimentation tank to drive... This component can scrape off residual sludge on the side walls and bottom plate of the sedimentation tank and push the sediment to the designated discharge position. However, unlike existing technologies, it is equipped with a linkage drive component. The scraping component itself rotates, which in turn drives the linkage drive component to generate electrical energy. This electrical energy is alternating current. Utilizing the periodic characteristics of alternating current, the scraping structure is periodically extended and retracted, and the rotational motion is also in progress. With automatic adjustment, it realizes both scraping and pushing movements, without the need for an additional drive source. This reduces energy consumption and eliminates the need to waste extra time cleaning the sedimentation tank, thereby improving wastewater treatment time. Attached Figure Description

Detailed Implementation

[0020] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0021] Please refer to Figures 1-14 The present invention discloses a multi-stage rectification adaptive sedimentation treatment device for wastewater, such as... Figures 1-2 The system includes a second sedimentation tank 1, a scraping and pushing assembly 2, a filter outlet tank 3, a filter inclined plate 4, a first reaction tank 5, a mixing assembly 6, a flocculation and stirring assembly 7, a first sedimentation tank 8, a first flocculation tank 9, a second reaction tank 10, a second flocculation tank 20, and a linkage drive assembly 30. Several first reaction tanks 5 are arranged side-by-side and interconnected. The first flocculation tank 9 is installed behind the first reaction tank 5. A first sedimentation tank 8 is located to the left of the first flocculation tank 9 and the first reaction tank 5. The front end of the first flocculation tank 9 is connected to the first reaction tank 5, and its left side is connected to the first sedimentation tank 8. Several second reaction tanks 10 are arranged side-by-side and installed behind the first sedimentation tank 8. A second flocculation tank 20 is located behind the second reaction tank 10. The second reaction tank 1... The first reaction tank 5 and the second reaction tank 10 are connected. The second sedimentation tank 1 is located on the right side of the second flocculation tank 20. The second sedimentation tank 1 is connected to the second flocculation tank 20. The mixing components 6 are arranged in pairs and installed above the first reaction tank 5 and the second reaction tank 10 respectively. The flocculation stirring components 7 are arranged in pairs and installed above the first flocculation tank 9 and the second flocculation tank 20 respectively. The scraping and pushing components 2 are installed above the first sedimentation tank 8 and the second sedimentation tank 1. Several filter inclined plates 4 and several filter outlet tanks 3 are installed inside the first sedimentation tank 8 and the second sedimentation tank 1. The linkage drive component 30 is installed in the scraping and pushing components 2. The first reaction tank 5, the first flocculation tank 9, and the first sedimentation tank 8 have the same structure as the second reaction tank 10, the second flocculation tank 20, and the second sedimentation tank 1 respectively. Two sets of sedimentation devices are used to achieve secondary purification of sewage and improve water treatment efficiency. The scraping and pushing component 2, the mixing component 6 and the flocculation and stirring component 7 agitate the water and accelerate sedimentation. The filter inclined plate 4 blocks the flocs and allows the purified water to flow through. The purified water is discharged through the filter outlet tank 3. It should be noted that the purified water in the first sedimentation tank 8 enters the second reaction tank 10 through the filter outlet tank 3. The water inlet of the filter outlet tank 3 enters through the side wall and flows out from both ends. The side wall of the filter outlet tank 3 has a serrated structure to block large particles and prevent them from entering the next stage of the reaction tank.

[0022] In a specific embodiment, such as Figure 3The first reaction tank 5 has a connecting groove 51 on its side wall, which connects two first reaction tanks 5. A water passage hole 52 is opened at the bottom of the side wall of the first reaction tank 5, which connects the first reaction tank 5 to the first flocculation tank 9. Since several first reaction tanks 5 are connected in series, the connecting groove 51 is needed to ensure that the water levels in the first reaction tanks 5 are equal. The water passage hole 52 is used to allow water from the first reaction tank 5 to enter the first flocculation tank 9.

[0023] In a specific embodiment, such as Figure 4 The first flocculation tank 9 has a through groove 92 on its side wall, which connects the first flocculation tank 9 to the first sedimentation tank 8. The bottom of the first flocculation tank 9 has a round hole 91. The through groove 92 is used to connect the first sedimentation tank 8, while the round hole 91 is used to install the T-shaped pipe 40 to allow the sludge sediment to be returned.

[0024] In a specific embodiment, such as Figure 5 A baffle 81 is installed on the bottom plate of the first sedimentation tank 8. An inclined plate 82 is installed between one end of the baffle 81 and the bottom plate of the first sedimentation tank 8. An annular ramp 83 is provided on the bottom plate of the first sedimentation tank 8 between the other end of the inclined plate 82 and the side plate of the first sedimentation tank 8. A frustum-shaped storage trough 84 is also opened on the bottom plate of the first sedimentation tank 8. The frustum-shaped storage trough 84 is located below the annular ramp 83. Several arc-shaped walls 85 are provided on the inclined plate 82 and the side plate wall of the first sedimentation tank 8. The arc-shaped walls 85 are located above the annular ramp 83. A guide plate 86 is provided between the two side walls of the first sedimentation tank 8. The guide plate 86 is parallel to the baffle 81. By setting baffle 81, the flow path of flocs is increased, allowing more sewage to mix with chemicals to produce flocs. Inclined plate 82 is used to guide the flocs and prevent them from falling to the bottom of baffle 81 and forming sludge. Guide plate 86 is used to guide the flow of water. Annular slope 83 is used to allow the sludge formed by floc sedimentation to fall into frustum-shaped collection tank 84. Arc wall 85 is used to guide the flow of sludge.

[0025] In a specific embodiment, such as Figure 6 The mixing component 6 includes a first rotary motor 61, a placement plate 62, a drive rod 63, a rotating disk 64, and conical teeth 65. The placement plate 62 is installed on top of several first reaction tanks 5, and several first rotary motors 61 are mounted on the top of the placement plate 62. The drive rod 63 is installed at the bottom output end of the first rotary motors 61, and its bottom passes through the placement plate 62. Several rotating disks 64 are mounted on the drive rod 63, and several conical teeth 65 are installed at the bottom of the rotating disks 64. When the first rotary motor 61 is started, the drive rod 63 drives the rotating disks 64 and conical teeth 65 to rotate at high speed, which vigorously stirs and mixes the wastewater with the added agents (such as coagulants) to form fine flocs.

[0026] In a specific embodiment, such as Figure 7 The flocculation and stirring assembly 7 includes a connecting plate 71, a second rotary motor 72, an annular guide barrel 73, connecting plates 74, a rotating shaft 75, and toothed plates 76. The connecting plate 71 is installed above the first flocculation tank 9 or the second flocculation tank 20. The second rotary motor 72 is installed on top of the connecting plate 71, and a rotating shaft 75 is installed at the bottom output end of the second rotary motor 72. The bottom of the rotating shaft 75 extends out of the connecting plate 71. Several connecting plates 74 are installed on the side wall of the first flocculation tank 9. The annular guide barrel 73 is installed between the several connecting plates 74, and several toothed plates 76 are installed on the bottom periphery of the rotating shaft 75. The annular guide barrel 73, installed between the several connecting plates 74, forms an annular guiding space, allowing the water flow in the flocculation tank to circulate and promoting floc collision. When the second rotary motor 72 drives the rotating shaft 75 to rotate, the toothed plates 76 rotate accordingly, gently stirring the wastewater and helping small flocs grow into larger flocs. At the same time, the annular guide barrel 73 restricts the water flow path, preventing turbulence from damaging the flocs.

[0027] In a specific embodiment, such as Figures 8-9 The scraping and pushing assembly 2 includes a drive motor 21, a first gear 22, a second gear 23, a mounting plate 24, a limiting sleeve 25, a rotating shaft 26, a first scraper 27, a sleeve 28, an annular sleeve 29, a trapezoidal plate 210, a bushing 211, a second scraper 212, a connecting rod 214, an I-shaped slide rod 215, a linkage component 216, a drive rack 217, a permanent magnet 218, and an annular scraper head 219. The mounting plate 24 has an internal mounting groove and is mounted on the top of the first sedimentation tank 8 or the second sedimentation tank 1. The drive motor 21 is mounted on the top of the mounting plate 24. The first gear 22 and the second gear 23 are installed in the mounting groove and mesh with each other. The first gear 22 is mounted on the bottom output end of the drive motor 21. The limiting sleeve 25 is mounted on the bottom of the mounting plate 24. The bushing 211 is mounted on the bottom of the frustum-shaped receiving groove 84. The top of the rotating shaft 26 is mounted in the second gear 23. The bottom of the rotating shaft 26 passes through the base plate of the mounting plate 24 and the limiting sleeve 25, and is inserted into the bushing 211. Several trapezoidal plates 210 are installed on the bottom periphery of the rotating shaft 26. The trapezoidal plates 210 are set in the frustum-shaped storage groove 84. The annular sleeve 29 is installed on the rotating shaft 26 and is positioned above the trapezoidal plates 210. Several sleeves 28 are provided on the outer periphery of the annular sleeve 29. An annular scraper 219 is installed at the bottom of the sleeve 28. I-shaped slide rod 2 15 is slidably connected in sleeve 28. A connecting rod 214 is installed on the outer end of the I-shaped slide rod 215. A first scraper 27 is installed on the outer end of the connecting rod 214. The first scraper 27 has arc-shaped surfaces at both ends. A drive rack 217 is symmetrically arranged on the side of the middle part of the I-shaped slide rod 215. A permanent magnet 218 is provided on the inner end surface of the I-shaped slide rod 215. The upper end of the linkage component 216 is connected to the I-shaped slide rod 215. A second scraper 212 is connected to the bottom of the linkage component 216.

[0028] In this embodiment, the drive motor 21 drives the first gear 22 to rotate. The first gear 22 is a small gear, while the second gear 23 is a large gear. The small gear drives the large gear to achieve deceleration, because low-speed stirring is required during sedimentation. If the stirring is too fast, the sediment will be sent back to the flocculation tank. The rotation of the second gear 23 causes the rotating shaft 26 to rotate. The limiting sleeve 25 is a fixing component installed at the bottom of the mounting plate 24. An anisotropic magnet 301 is installed in the limiting sleeve 25. The rotation of the rotating shaft 26 will drive the annular sleeve 29 to rotate, which will eventually cause the sleeve 28 to rotate. The rotation of the sleeve 28 will cause the first scraper 27 and the second scraper 212 to rotate synchronously, thereby agitating the sediment. The trapezoidal plate 210 is used to agitate the sludge formed by sedimentation in the frustum-shaped collection tank 84, preventing the sludge from solidifying in the frustum-shaped collection tank 84. At the same time, the eddy current formed by the rotation will carry the sludge into the T-shaped pipe 40. The bushing 211 is used to stabilize the rotation of the rotating shaft 26 and prevent it from deviating.

[0029] In a specific embodiment, such as Figure 10The linkage component 216 includes a T-shaped connecting cylinder 2161, a threaded lifting rod 2162, a connecting rod 2163, a crossbar 2164, and a linkage gear 2165. The T-shaped connecting cylinders 2161 are arranged in pairs, with their tops installed on the inner wall of the top of the sleeve 28. The bottom of the T-shaped connecting cylinder 2161 is rotatably connected to the linkage gear 2165. The linkage gear 2165 has an internal thread groove at its center and meshes with the drive rack 217. The threaded lifting rods 2162 are arranged in pairs and are screwed into the two internal thread grooves. The two ends of the crossbar 2164 are connected to the bottom of the two threaded lifting rods 2162. The bottom of the crossbar 2164 is equipped with a connecting rod 2163. The bottom of the connecting rod 2163 passes through the sleeve 28 and the annular scraper head 219, and a second scraper 212 is installed at its end. The linkage component 216 is used to control the movement of the second scraper 212. Through the displacement of the I-shaped slide bar 215, the drive rack 217 causes the linkage gear 2165 to rotate at the bottom of the T-shaped connecting cylinder 2161. The internal thread structure of the linkage gear 2165 drives the threaded lifting rod 2162 to move vertically. The threaded lifting rod 2162 then moves the crossbar 2164, which in turn moves the connecting rod 2163 up and down. This causes the second scraper 212 to either conform to or move away from the annular ramp 83, achieving both pushing and scraping movements. It is important to note that during the outward movement of the I-shaped slide bar 215, the crossbar 2164 moves upward, meaning that sludge is first removed from the sidewall. After scraping, the second scraper 212 moves downward to scrape material from the annular ramp 83, preventing the formation of sludge. In cases of secondary bonding or sludge falling onto the second scraper 212, it is important to note that the lifting and lowering movement of the threaded lifting rod 2162 will not affect the movement of the I-shaped slide rod 215. All movements are driven by the linkage drive assembly 30 to prevent errors in movement. The annular scraper head 219 is used to scrape water off the connecting rod 2163 to prevent water from entering the sleeve 28. At the same time, the tapered shape at the outer end of the sleeve 28 also achieves the water scraping effect. The I-shaped slide rod 215 is I-shaped, and its wide structure at both ends prevents water from entering the annular sleeve 29. Even if water does enter the annular sleeve 29, only the electromagnet 303 protrudes from the side of the rotating shaft 26. As long as the protruding end of the electromagnet 303 is welded to the rotating shaft 26, water cannot enter the inner side of the rotating shaft 26, thus not affecting the operation of the linkage drive assembly 30, extending its service life, and preventing water pollution.

[0030] In a specific embodiment, such as Figures 11-13The upper side wall of the rotating shaft 26 has several rectangular slots. The linkage drive assembly 30 includes an anisotropic magnet 301, a coil 302, an electromagnet 303, and an energized coil 304. The anisotropic magnet 301 is installed inside the bottom of the limiting sleeve 25. Several coils 302 are arranged in the rotating shaft 26. A portion of one coil 302 passes through two symmetrical rectangular slots. An energized coil 304 is installed between the two ends of the coil 302. The electromagnet 303 is installed in the rotating shaft 26. Both ends of the electromagnet 303 pass through the rotating shaft 26. The two ends of the electromagnet 303 face the permanent magnet 218. The coil 302 is arranged outside the electromagnet 303. A coil 302 passes through the rectangular slot. The coil 302, being rectangular in shape, sweeps across the opposite magnet 301, conforming to the principle of a generator where a looped conductor cuts magnetic field lines, causing a current to flow through the coil 302. This current causes the electromagnet 303 to become magnetic. The principle behind this current generation is the same as that of an AC generator, satisfying Em=NBSω. Since the rotational angular velocity ω of the rotating shaft 26 is small, and the energized coil 304 has a certain resistance, the current generated by the coil 302 is small and will not cause a short circuit. The magnetism of the electromagnet 303 begins to drive the permanent magnet 218 to shift. It is important to note that two types of magnetism are generated at the two ends of the electromagnet 303. There are two methods for 218. One is that the permanent magnets 218 at both ends use the same magnetism. In this way, only one end of the I-shaped slide rod 215 is in an outward movement state, carrying the first scraper 27 to scrape the side wall. The first scraper 27 has an arc-shaped structure at both ends, which is used to scrape the mud at the corner. The other method is that the permanent magnets 218 at both ends use opposite magnets to realize the synchronous movement of the I-shaped slide rods 215 at both ends, realizing synchronous scraping at both ends. Since the coil 302 generates alternating current, the magnetic pole direction of the electromagnet 303 will change periodically, thereby driving the permanent magnet 218 to drive the I-shaped slide rod 215 to reciprocate in the sleeve 28, realizing the periodic scraping of the side wall by the first scraper 27.

[0031] In a specific embodiment, such as Figure 14 T-shaped pipes 40 are installed at the bottom of the first flocculation tank 9, the first sedimentation tank 8, the second flocculation tank 20, and the second sedimentation tank 1. One end of the T-shaped pipe 40 extends into the first sedimentation tank 8 or the second sedimentation tank 1, and the other end is located on the outermost side. A section of the T-shaped pipe 40 is also installed in the first flocculation tank 9 or the second flocculation tank 20. The T-shaped pipes 40 are used to return the sediment to the flocculation tanks for secondary use, while the remaining sludge is discharged through the T-shaped pipes 40.

[0032] When using this invention, as Figure 1As shown, wastewater flows into one of the first reaction tanks 5 through the inlet pipe on the side of the first reaction tank 5, and then through the connecting channel 51 to fill all three first reaction tanks 5. During the filling process, reaction reagents such as lime, calcium chloride, or PAC are added. At the same time as the wastewater is added, the mixing component 6 is started. After the reaction reagents are added, the high-speed stirring of the mixing component 6 mixes the reaction reagents and wastewater evenly and completes the destabilization of colloids. The mixed fluid enters the first flocculation tank 9 through the water passage 52. PAM coagulant is added to the first flocculation tank 9, and then the flocculation stirring component 7 stirs at low speed to form dense large flocs. The flocs are carried by the water and flow into the first sedimentation tank 8 through the channel 92. The filter inclined plate 4 blocks the flocs, and the flocs are intercepted by the filter inclined plate 4 and settle to the bottom of the first sedimentation tank 8. The scraping and pushing component 2 removes the flocs. The sediment is stirred and settled, and finally pushed into the frustum-shaped collection tank 84 by the scraping and pushing component 2. At the same time, the scraping and pushing component 2 also scrapes away the residual sediment on the side wall and bottom plate of the first sedimentation tank 8 to prevent sludge from adhering and causing problems such as reduced volume and difficulty in cleaning. The side wall of the first reaction tank 5 is also opened with a water inlet hole, which is connected to the output end of the filter outlet tank 3 in the first sedimentation tank 8. The water will then enter the second reaction tank 10 through the filter outlet tank 3. In the second reaction tank 10, reaction reagents such as lime, calcium chloride or PAC are added to carry out secondary reaction. The water after reaction enters the second flocculation tank 20. In the second flocculation tank 20, PAM coagulant is added to carry out secondary flocculation. Finally, secondary sedimentation is completed in the second sedimentation tank 1, making the sewage cleaner. Through multi-stage sedimentation treatment, the sewage treatment efficiency is significantly improved.

[0033] Traditional equipment for sedimentation and sludge removal connects the second scraper 212 to a hydraulic system. Hydraulic oil is supplied to drive the scraper 212 downwards, scraping away sludge from the bottom of the sedimentation tank. However, using a hydraulic system requires a hydraulic cylinder and pump. The hydraulic cylinder is often submerged in the water, necessitating pipelines to transport the hydraulic oil. Hydraulic pumps are typically electrically controlled, requiring them to be located outside the water body and connected via pipelines. This not only increases costs but also requires large quantities of hydraulic oil. Furthermore, the pipelines, constantly immersed in sewage and chemicals, are prone to corrosion and leaks, which can pollute the water and defeat the purpose of wastewater treatment. In this structure, the hydraulic pump is mounted on the rotating shaft 26, affecting its rotation. Existing devices also lack a structure for removing sludge from the side walls of the sedimentation tank, leading to reduced sedimentation volume and increased cleaning difficulty. To address the aforementioned problem, this structure incorporates a linkage drive assembly 30. A drive motor 21 rotates the rotating shaft 26. A magnet 301 of a different shape is housed within the limiting sleeve 25. The rotation of the rotating shaft 26 causes the coil 302 within it to rotate as well. As the coil 302 rotates, it sweeps across the magnet 301, generating a cutting motion of magnetic field lines. Based on the principle of magnetism generating electricity, a current is generated in the coil 302 when it sweeps across it. This current causes the electromagnet 303 to become magnetic, driving the permanent magnet. The 218 carries the I-shaped slide bar 215 and reciprocates along the sleeve 28, while the rotating shaft 26 carries the annular scraper head 219 and rotates in the sedimentation tank. In this way, the sludge scraping operation on the inner wall of the sedimentation tank can be realized. The I-shaped slide bar 215 also drives the linkage component 216 to move, so that the second scraper 212 moves up and down, realizing the conveying of scraped sludge and the scraping operation on the bottom surface of the sedimentation tank. Moreover, the transmission structure is not set in the water and does not add an additional drive source, saving costs while ensuring that there are no impurities in the water.

[0034] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
