Description

Technical Field

[0001] This utility model relates to the field of vertical flow sedimentation tower technology, specifically a vertical flow sedimentation single cone tower structure. Background Technology

[0002] Vertical flow sedimentation tanks are commonly used equipment for solid-liquid separation in wastewater treatment. They are treatment devices that use gravity settling to remove suspended particles with a density greater than water from the water. They are one of the most widely used treatment units in wastewater treatment. They mainly achieve solid-liquid separation by controlling the upward flow velocity of wastewater to be less than the natural settling velocity of sludge, and can be used for primary wastewater treatment.

[0003] Currently available vertical flow sedimentation towers have several drawbacks in wastewater treatment. Traditional sedimentation towers typically inject wastewater and chemicals directly into the tower body, relying on natural fluid diffusion for mixing. This makes it difficult for the chemicals to disperse quickly and evenly in the wastewater, leading to localized high or low concentrations. In areas with insufficient chemicals, suspended particles cannot fully aggregate, forming small, loose flocs with poor settling performance, easily floating with the clear water. In areas with excessive chemicals, waste occurs, potentially causing secondary pollution and severely impacting subsequent sedimentation efficiency and effluent quality. Furthermore, the colloidal particles and microbial flocs in sludge are sticky. During sludge discharge, as the moisture content decreases, particles easily interlock through van der Waals forces and hydrogen bonds, forming a stable, arch-like bridging structure above the discharge port. Undischarged sludge accumulates below this bridging, gradually reducing the effective flow cross-section of the discharge port, and may even completely block the channel, preventing smooth sludge discharge. This not only reduces sludge discharge efficiency, but also causes anaerobic fermentation and odor due to long-term sludge retention, significantly increasing the difficulty of manual cleaning and equipment maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a vertical flow sedimentation single cone tower structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vertical flow sedimentation single cone tower structure includes:

[0007] A sedimentation tower is provided, with a support plate fixedly connected to the top of the sedimentation tower, a central cylinder fixedly connected to the center of the support plate, a sewage inlet fixedly connected to the top of the central cylinder, and a mixing structure provided inside the central cylinder. When sewage and chemicals enter the central cylinder from the sewage inlet, under the guidance of the mixing structure, a swirling flow is formed, allowing the chemicals and sewage to fully contact and mix, thereby ensuring that the chemicals and sewage are fully mixed.

[0008] A single-cone tower is fixedly connected to the bottom of a sedimentation tower, and a sludge discharge port is provided at the bottom of the single-cone tower for discharging the settled sludge.

[0009] The inner wall of the single cone tower is provided with a side opening, and a high-pressure water flushing component is installed in the side opening. The high-pressure water flushing component is set towards the sludge discharge port inside the single cone tower and can intermittently flush water into the sludge discharge port area. The impact force of the water flow will destroy the bridging structure formed by the sludge near the sludge discharge port, ensuring that the sludge is discharged smoothly.

[0010] Preferably, the high-pressure flushing assembly includes a high-pressure nozzle, which is fixedly connected to the end of the high-pressure water inlet. A connecting flange is integrally formed on the outer wall of the high-pressure water inlet. The connecting flange is sealed to the flange of the external high-pressure water pipe by bolts. A nozzle is provided on the side of the high-pressure nozzle facing the sludge discharge port at the bottom of the single cone tower. The water outlet path of the nozzle points directly to the sludge discharge port area to enhance the targeted flushing.

[0011] Preferably, the mixing structure includes a spiral guide plate. The outer edge of the spiral guide plate is detachably connected to the inner wall of the central cylinder by bolts, which facilitates the maintenance or replacement of the spiral guide plate in the future. The center of the spiral guide plate has a vertical flow space, which not only ensures the overall fluidity of the fluid during the swirling mixing process, but also guides the sewage and the agent to form a stable swirling flow through the spiral trajectory, thereby enhancing the shearing and mixing effect of the two. At the same time, the detachable design reduces the difficulty of equipment maintenance and improves the practicality of the structure.

[0012] Preferably, the spiral guide plate has multiple through holes, which are evenly distributed along the extension direction of the spiral guide plate. When the sewage and the agent flow along the spiral trajectory, some of the fluid will pass through the through holes to form a flow-through effect, which promotes the mutual penetration and exchange of fluids in different areas, further tears the liquid clumps to increase the contact area, strengthens the turbulence effect in the swirling mixing process, improves the mixing uniformity of the agent and sewage, and avoids local fluid stagnation.

[0013] Preferably, the bottom of the central cylinder has a sewage outlet with an opening diameter larger than the diameter of the central cylinder body. Below the sewage outlet, a "umbrella"-shaped guide cone is provided. The guide cone is fixed to the bottom of the sewage outlet by four fixing rods welded together. One end of each fixing rod is welded to the outer edge of the guide cone, and the other end is welded to the outer edge of the bottom of the sewage outlet. This allows the mixed sewage to flow out of the sewage outlet and spread evenly in all directions under the guidance of the guide cone, avoiding direct impact on the sludge at the bottom of the tower.

[0014] Preferably, the bottom of the guide cone is welded and fixed to the middle of the second support rod, and the two ends of the second support rod are respectively welded to the inner wall of the sedimentation tower through the first welding plate. One side of the first welding plate is welded and fixed to the inner wall of the sedimentation tower, and the other side is welded to the end of the second support rod. The second support rod forms a stable support for the guide cone, ensuring that the guide cone remains structurally stable under fluid impact.

[0015] Preferably, a plurality of second welding plates are fixedly connected to the outer wall of the central cylinder. The first support rod passes through the second welding plate and is fixedly connected to the second welding plate. The two ends of the first support rod are respectively welded to the inner wall of the sedimentation tower through the first welding plate. The cooperation between the first support rod and the second welding plate forms radial support for the central cylinder, thereby enhancing the installation stability of the central cylinder in the tower.

[0016] Preferably, a first reinforcing ring is fixedly connected to the top of the single-cone tower, a first support leg is fixedly connected to the lower end face of the first reinforcing ring, and a reinforcing rod is provided between adjacent first supports.

[0017] Preferably, a second reinforcing ring is fixedly connected to the outer wall of the middle part of the single cone tower, a second support is fixedly connected to the lower end face of the second reinforcing ring, and a reinforcing rod is provided between adjacent second supports.

[0018] Preferably, the outer wall of the sedimentation tower is provided with multiple annular support trusses at intervals along the vertical direction. The annular support trusses are fixedly connected to the outer wall of the sedimentation tower to enhance the overall structural strength of the tower. An overflow weir is arranged around the inner side of the top of the sedimentation tower. When the clear water in the tower rises to the height of the overflow weir, it can overflow evenly through the overflow weir, ensuring that the clear water flows out stably in a horizontal state and improving the uniformity and smoothness of clear water collection.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention, by setting a spiral guide plate with through holes, allows wastewater and chemicals to flow along the spiral trajectory after entering the central cylinder. The through-hole flow effect promotes fluid cross-penetration and tears liquid clumps. Combined with the guide cone plate, it evenly diffuses the mixed liquid into the sedimentation tower, avoiding uneven local chemical concentrations and preventing water flow from impacting sludge and interfering with sedimentation. This achieves a continuous effect of efficient chemical mixing and stable sedimentation, improving pollutant coagulation efficiency and sedimentation quality.

[0021] This invention, by setting up a drain valve and a high-pressure flushing component, combined with PLC control, first triggers the high-pressure flushing component when the sludge accumulates to a set amount in the single-cone tower and the sludge discharge program is started. The high-pressure water flow is delivered to the nozzle through the high-pressure water inlet, and the nozzle fires a high-intensity water flow towards the sludge discharge port area to break up the sludge bridging structure. Then the drain valve opens, and the sludge is smoothly discharged under the guidance of gravity and the cone surface, effectively avoiding blockage of the sludge discharge port, ensuring continuous and stable sludge discharge, reducing manual cleaning intervention, and improving sludge discharge efficiency and equipment operation reliability.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Please see Figures 1 to 8 This utility model provides a technical solution:

[0034] A vertical flow sedimentation single cone tower 3 structure, wherein the upper part is a vertically set sedimentation tower 1, and the lower part is a fixedly connected inverted cone-shaped single cone tower 3.

[0035] Compared to traditional ground sedimentation tanks, the vertical flow sedimentation single cone tower 3, through the slope guidance of the inverted cone-shaped single cone tower 3 and the design of the bottom sludge discharge port 4, allows the settled sludge to naturally gather towards the sludge discharge port 4 under the action of gravity. This not only allows the sludge slurry discharged from the bottom of the single cone tower 3 to have a sludge content of up to 40%, increasing the sludge concentration to reduce subsequent treatment costs, but also avoids the sludge scattering problem of traditional sedimentation tanks because the sludge is discharged centrally through a closed structure, keeping the surrounding ground clean and hygienic. At the same time, the overall tower-style three-dimensional design saves more than 50% of the floor space compared to traditional ground sedimentation tanks, greatly improving space utilization.

[0036] A horizontal support plate 6 is fixedly connected to the top of the sedimentation tower 1. A central cylinder 11 is vertically fixed at the center of the support plate 6. The top of the central cylinder 11 is provided with a sewage inlet 7 for receiving sewage to be treated and reagents.

[0037] In existing technologies, wastewater and chemicals are mostly injected into the sedimentation tower 1 simultaneously or separately, relying on natural fluid diffusion to achieve mixing. However, chemicals are difficult to disperse quickly and evenly in wastewater, easily leading to localized excessively high or low concentrations. In areas with insufficient chemical concentration, suspended particles in the wastewater cannot fully coagulate, forming small, loose flocs with poor settling performance, easily floating with the water flow or remaining suspended in the clear water. Conversely, areas with excessive chemical concentration will result in chemical waste and may even cause secondary pollution. Therefore, a mixing structure is installed inside the central cylinder 11.

[0038] The hybrid structure includes a spiral guide plate 15, which is disposed inside the central cylinder 11 (e.g., Figure 6 As shown), the outer edge of the spiral guide plate 15 is detachably connected to the inner wall of the central cylinder 11 by bolts, which facilitates later maintenance and replacement; a vertical flow space is left in the center, which not only ensures the overall fluid flow, but also guides the sewage and the agent to form a stable swirling flow along the spiral trajectory, thereby enhancing the shearing and mixing effect.

[0039] In this embodiment, the spiral guide plate 15 is uniformly provided with multiple through holes 1501 along its extension direction. The pore size and distribution density of these through holes 1501 are adaptively designed so as not to destroy the core function of the spiral guide plate 15 in guiding the fluid to form a swirling flow, and to form an efficient cross-flow effect when the fluid flows along the spiral path. When the mixed fluid of sewage and agent flows along the surface of the spiral guide plate 15, some fluid will pass through the through holes 1501 from one side to the other due to the pressure difference. This cross-flow effect breaks the inertia of the fluid flowing along a single spiral trajectory, promoting the mutual penetration and cross-mixing of fluids in different areas. At the same time, the local turbulence generated during the cross-flow process will further tear apart the incompletely mixed liquid clumps, dispersing the agent particles more evenly into the sewage, greatly increasing the contact area and collision frequency between the agent and the sewage, thereby ensuring that the sewage and agent are quickly and fully mixed in the central cylinder 11.

[0040] It should be noted that multiple agent injection pipes (not shown in the figure) are evenly arranged circumferentially on the upper side wall of the central cylinder 11. These agent injection pipes extend radially along the central cylinder 11, with one end connected to the interior of the central cylinder 11 and the other end connected to an external agent storage tank via a pipe, allowing for precise delivery of the agent into the sewage flow within the central cylinder 11. To achieve dynamic control of the agent injection volume, a flow regulating valve is installed on each agent injection pipe. This valve can adaptively adjust based on real-time sewage flow data and water quality monitoring results (such as suspended solids concentration, pH value, etc.) to ensure that the agent and sewage are mixed in the optimal ratio. The circumferential distribution of the agent injection pipes, the connection structure with the external storage tank, and the setting of the flow regulating valve are all conventional technical means in this field for achieving quantitative agent injection. The specific connection methods, control logic, and other existing technologies have been fully disclosed and will not be elaborated here.

[0041] The bottom of the central cylinder 11 is provided with a sewage outlet 1101 (e.g. Figure 5 As shown), its opening diameter is larger than the main body diameter of the central cylinder 11, which can accelerate the outflow of the mixed fluid; a "umbrella"-shaped guide cone plate 13 is provided directly below the sewage outlet 1101. The guide cone plate 13 is fixed by welding four fixing rods 14. One end of the fixing rod 14 is welded to the outer edge of the guide cone plate 13, and the other end is welded to the bottom outer edge of the sewage outlet 1101.

[0042] In this embodiment, after the mixed wastewater flows out through the wastewater outlet 1101, it is guided by the guide cone plate 13 to diffuse evenly around the inside of the sedimentation tower 1, avoiding direct impact on the sludge at the bottom of the tower. The umbrella-shaped guide cone plate 13 can divert the concentrated outflowing wastewater into gentle water flows radiating in all directions, so that the wastewater mixed with the agent is evenly dispersed in the sedimentation tower 1, ensuring that the wastewater flows slowly downward at a stable flow rate. This effectively prevents the settled sludge from being stirred up by the local water flow being too fast, ensuring that the sludge settles in an orderly manner under the action of gravity, and avoiding interference with the stable flow state of the sedimentation area, thus affecting the sedimentation efficiency.

[0043] The bottom of the flow guide cone 13 is welded and fixed to the middle of the second support rod 12. The two ends of the second support rod 12 are respectively connected to the inner wall of the sedimentation tower 1 through the first welding plate 9. One side of the first welding plate 9 is welded to the inner wall of the sedimentation tower 1, and the other side is welded to the end of the second support rod 12. This support structure ensures that the flow guide cone 13 remains stable under fluid impact. The multiple fixing structures enable the flow guide cone 13 to have sufficient impact resistance, and it can withstand fluid impact for a long time without shaking, which significantly extends the service life of the structure.

[0044] Multiple second welding plates 10 (such as...) are fixedly connected to the outer wall of the central cylinder 11. Figure 5 As shown, the first support rod 8 passes through and is fixed to the second welding plate 10. Its two ends are also welded to the inner wall of the sedimentation tower 1 through the first welding plate 9. The cooperation between the first support rod 8 and the second welding plate 10 forms radial support for the central cylinder 11, further enhancing the installation stability of the central cylinder 11 in the tower.

[0045] Multiple annular support trusses 2 are arranged vertically at intervals on the outer wall of the sedimentation tower 1. The trusses are fixedly connected to the outer wall of the sedimentation tower 1, which can effectively distribute the internal and external loads borne by the tower body and enhance the overall structural strength of the sedimentation tower 1. A horizontal overflow weir 5 is arranged around the inner side of the top of the sedimentation tower 1. When the mixed wastewater completes sedimentation in the tower and the clear water rises to the height of the overflow weir 5, the clear water can overflow evenly through the overflow weir 5, ensuring that the clear water flows out stably in a horizontal state and improving the uniformity and smoothness of clear water collection.

[0046] It should be noted that the overflow weir 5 is preferably a sawtooth structure, with its sawtooth top surface continuously distributed circumferentially along the inner side of the top of the sedimentation tower 1. During the vertical flow sedimentation process, the mixed wastewater achieves solid-liquid separation in the tower due to gravity. Suspended particles such as silt in the wastewater settle downwards under gravity and eventually converge into the lower single-cone tower 3; while the clarified water rises in layers. As the central cylinder 11 continuously injects mixed wastewater into the bottom of the tower, the total amount of water in the tower gradually increases, and the clear water layer rises accordingly. When the water level rises to the height of the sawtooth overflow weir 5, the clear water overflows evenly along the sawtooth gaps under gravity and enters the external clear water collection system. The sawtooth design can balance the water flow pressure through multiple evenly distributed overflow gaps, ensuring that clear water overflows synchronously from different locations, effectively maintaining the horizontal state of the water surface in the tower, avoiding uneven clear water collection caused by excessively high or low local water levels, and further improving the stability and efficiency of clear water collection.

[0047] The bottom of sedimentation tower 1 is welded to the top of single-cone tower 3. A first reinforcing ring 301 is provided at the connection to enhance the stability of the connection. Single-cone tower 3 has an inverted cone shape, and its inner wall slope design can guide the sedimented sludge to accumulate to the bottom. The lower end face of the first reinforcing ring 301 has first legs 302 evenly distributed, and adjacent first legs 302 are connected by reinforcing rods 303. A second reinforcing ring 304 is also fixed to the middle outer wall of single-cone tower 3. The lower end face of the second reinforcing ring 304 is provided with second legs 305, and adjacent second legs 305 are also provided with reinforcing rods 303. The double-ring double-leg structure enhances the deformation resistance of single-cone tower 3.

[0048] The bottom center of the single cone tower 3 has a sludge discharge port 4. The settled sludge is guided by gravity and the cone surface to gather at the sludge discharge port 4 and is finally discharged through the sludge discharge port 4.

[0049] It should be noted that existing technologies typically employ two methods for sludge discharge from the bottom of sedimentation tower 1: one is natural sludge discharge relying on hydrostatic pressure, using the pressure generated by the sewage level inside the tower to push the sludge out from the sludge discharge port 4; the other is forced discharge using pumps or similar equipment, employing external force to extract the sludge. In this embodiment, to achieve flexible control of the sludge discharge process, a drain valve is preferably installed at the sludge discharge port 4 at the bottom of the single-cone tower 3. The timing and flow rate of sludge discharge can be precisely controlled by opening and closing the valve, adapting to the sludge discharge requirements under different operating conditions. The specific structural form of this drain valve, its connection method with the sludge discharge port 4, and its installation process are all conventional technologies in this field and will not be described in detail here.

[0050] The inner wall of the single cone tower 3 is provided with a side opening 1601, and a high-pressure flushing assembly is installed in the opening: the assembly includes a high-pressure nozzle 18, which is fixed to the end of the high-pressure water inlet 16. The outer wall of the high-pressure water inlet 16 is integrally formed with a connecting flange 17, which is sealed to the flange of the external high-pressure water pipe by bolts; the side of the high-pressure nozzle 18 is provided with a nozzle 19 facing the sludge discharge port 4, and its water outlet path points directly to the area of ​​the sludge discharge port 4.

[0051] During the sludge discharge process, as sludge continuously accumulates and is discharged from discharge port 4, some sludge, due to its reduced moisture content and interparticle adhesion, easily forms a bridging structure resembling an "arch" around discharge port 4. This is because the colloidal particles and microbial flocs in the sludge have a certain degree of viscosity. When the sludge discharge flow rate fluctuates or the sludge concentration is high, the particles easily interlock through van der Waals forces, hydrogen bonds, and other forces, forming a relatively stable network structure above discharge port 4. Undischarged sludge continues to accumulate below the bridging structure. This bridging structure gradually reduces the effective flow cross-section of discharge port 4, and may even completely block the channel, preventing subsequent sludge from being discharged smoothly. This not only affects sludge discharge efficiency but may also cause anaerobic fermentation and odor production due to long-term sludge retention, increasing the difficulty of equipment cleaning.

[0052] In this embodiment, the high-pressure flushing component is installed on the inner wall of the single-cone tower 3, diagonally above the sludge discharge port 4. Its high-pressure water inlet 16 is connected to the external high-pressure water source pipeline through the connecting flange 17 to achieve a sealed connection, ensuring stable water supply pressure without leakage. The start-up, shutdown, and operation of this component are centrally controlled by the PLC control system. During the sludge discharge process, the high-pressure flushing component is started intermittently according to the logic set by the PLC: before each sludge discharge program starts, the PLC first triggers the operation of the high-pressure flushing component. The high-pressure water flow is delivered to the high-pressure nozzle 18 through the high-pressure water inlet 16, and a high-intensity, high-velocity high-pressure water flow is emitted from the nozzle 19 to the sludge discharge port 4. The impact force of the water flow instantly disperses the sludge bridging structure that is about to form or has already begun to form. The dispersed sludge is then smoothly discharged with the subsequent sludge discharge process. During the sludge discharge process, the PLC can also start a secondary flushing in a timely manner according to the sludge concentration monitoring data to further prevent the sludge discharge port 4 from becoming blocked. This not only efficiently destroys the bridging structure between particles but also avoids water waste, ensuring that the sludge discharge port 4 remains unobstructed during long-term operation.

[0053] Specifically, the preferred PLC is the Siemens S7-1200 series or a model with equivalent performance.

[0054] In use, this invention first continuously injects wastewater into the central cylinder 11 through the wastewater inlet 7 at the top. Simultaneously, the chemical injection pipe on the upper side wall of the central cylinder 11 precisely injects chemicals through a flow regulating valve based on real-time wastewater flow and water quality data. The wastewater and chemicals flow along the spiral trajectory of the spiral guide plate 15 within the central cylinder 11, and are fully mixed under the synergistic effect of swirling shearing and the through-flow effect of the through-hole 1501, forming a uniform mixture.

[0055] After the mixed liquor flows out through the wastewater outlet 1101 at the bottom of the central cylinder 11, it is guided by the "umbrella"-shaped guide cone 13 to diffuse evenly around the inside of the sedimentation tower 1, flowing slowly downwards at a stable flow rate. During this process, the suspended particles in the mixed liquor gradually settle under the action of gravity, and the sludge slides down the inner wall of the sedimentation tower 1, eventually gathering at the bottom sludge discharge port 4 under the guidance of the cone surface of the single cone tower 3; while the clarified water stratifies upwards. As the water volume in the tower continues to increase, when the clear water rises to the height of the top sawtooth overflow weir 5, it overflows evenly along the overflow gap and enters the clear water collection system.

[0056] When the sludge in the single cone tower 3 accumulates to the set amount, the sludge discharge program is started. Before the sludge is discharged, the PLC control system first triggers the high-pressure flushing component to operate, spraying high-pressure water into the sludge discharge port 4 area through nozzle 19 to break up any possible sludge bridging structures. Then the drain valve at the sludge discharge port 4 is opened, and the sludge is discharged through the sludge discharge port 4 under the guidance of gravity and the cone surface.

[0057] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
