Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a phosphate wastewater precipitation and separation device. Background Technology

[0002] Phosphate wastewater mainly originates from industries such as chemical, electroplating, phosphate chemical, agricultural, and food processing. Excessive discharge leads to eutrophication, causing severe environmental problems such as algal blooms, water quality deterioration, and ecological imbalance. Therefore, effective treatment of phosphate wastewater is a crucial aspect of environmental protection. Currently, phosphate wastewater treatment technologies mainly include chemical precipitation, biological methods, adsorption, and membrane separation. Chemical precipitation involves adding calcium, iron, or aluminum salts to form insoluble phosphate precipitates, thus efficiently removing phosphate. This process is simple to operate, has a high removal rate, and is widely used in industrial wastewater treatment. Biological methods utilize polyphosphate-accumulating bacteria to excessively absorb phosphorus under alternating anaerobic and aerobic conditions, suitable for treating low-concentration phosphorus-containing wastewater, but are significantly affected by water quality fluctuations. Adsorption and membrane separation can be used as advanced treatment methods to further reduce the phosphorus concentration in the effluent, achieving high-standard discharge or water reuse.

[0003] In the process of treating phosphate wastewater, insufficient dosage of reagents such as calcium salts, aluminum salts, or iron salts used in chemical precipitation methods will result in phosphate ions in the wastewater not reacting sufficiently to form precipitates, leading to a decrease in phosphate removal rate and difficulty in achieving stable phosphorus concentration in the effluent, which may cause the risk of eutrophication of the water body. On the other hand, excessive dosage not only wastes reagents and increases treatment costs, but may also leave excessive metal ions in the effluent, affecting subsequent biological treatment units or causing secondary pollution.

[0010] Preferably, a rolling bearing is fixed on the outer surface of the rotating frame, and the outer ring of the rolling bearing is fixed at the inner ring of the fixed ring. A plurality of evenly distributed material passages are opened on the upper surface of the rotating frame. The material passages opened on the upper surface of the rotating frame are frictionally adapted to the lower surface of the fixed ring. A rotating funnel is fixed on the lower surface of the rotating frame, and the rotating funnel is located directly above the circular opening on the upper surface of the storage box.

[0011] Preferably, an arched extrusion frame is fixedly provided on the side of the upper surface of the rotating frame, and a roller is slidably connected to the inner cavity of the sliding frame, with the arched extrusion frame and the outer surface of the roller being frictionally adapted.

[0013] This invention provides a phosphate wastewater precipitation and separation device. It has the following beneficial effects: 1. This phosphate wastewater sedimentation and separation device, by setting up a pressurization mechanism, is the "water pressure lifting unit" of the device. It uses the rotation of the spiral blades to pressurize the wastewater entering the transfer tank, generating a water flow with sufficient kinetic energy to drive the subsequent powder feeding mechanism.

[0014] II. The phosphate wastewater precipitation and separation device is equipped with a powder feeding mechanism, which is the "quantitative dosing unit" of the device.

[0015] Third, the phosphate wastewater sedimentation and separation device is equipped with a drive mechanism, which is the "energy conversion and transmission unit" of the device.

[0016] IV. This phosphate wastewater sedimentation and separation device features a fixed ring, which serves as the base for the powder feeding mechanism. The inner ring is fixed to the outer surface of the transfer box, while the outer ring connects to the inner wall of the packaging box. Three rotationally symmetrical cavities on its upper surface accommodate components such as the sliding ring and springs; each cavity corresponds to the feeding of a specific reagent. A track groove provides a guide channel for the vertical movement of the sliding frame. The sliding ring slides up and down within the cavities of the fixed ring, driving the material-permeable frame and the conical blocking block to move, thus controlling the timing and amount of reagent feeding.

[0017] V. This phosphate wastewater sedimentation and separation device features a permeable frame connecting a sliding frame and a conical blocking block. The frame is hollow, allowing reagents to flow out from the side or bottom of the permeable frame when the conical blocking block moves downwards. The conical blocking block forms a sealed fit with a sealing ring on the lower surface of the storage tank. When the sliding ring is driven upwards, the conical blocking block disengages from the sealing ring, opening the outlet and allowing the reagents to flow out. The storage tanks separately store different reagents such as lime, flocculant, and coagulant aid, enabling independent storage and quantitative dosing of various reagents. Three rotationally symmetrical storage tanks correspond to three cavities, ensuring uniform and continuous reagent dosing. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figures 1-9As shown, the present invention provides a technical solution: a phosphate wastewater sedimentation and separation device, including a storage tank 1, a drain valve 9 penetrating the outer side of the storage tank 1, a first support frame 2 fixedly mounted on the upper surface of the storage tank 1, and a covering box 3 fixedly mounted on the top of the first support frame 2. By setting the storage tank 1 as the main container for wastewater sedimentation and separation, it receives the treated wastewater, allowing phosphate precipitates to settle at the bottom, and the upper clear liquid to be discharged through the drain valve 9. The drain valve 9 is used to discharge the separated upper clear liquid from the storage tank 1, achieving solid-liquid separation. Simultaneously, before separation, the wastewater to be separated can be poured into the inner cavity of the storage tank 1 through the drain valve 9. The first support frame 2 lifts the covering box 3 above the storage tank 1, providing installation space for the powder feeding mechanism 7 and the drive mechanism 8. The covering box 3 serves as a protective shell for the powder feeding mechanism 7, and also includes: A transfer box 4 has a second support frame 5 fixed to its upper surface, and a pressurizing mechanism 6 for driving the feeding is fixed inside the cavity of the second support frame 5. The transfer box 4 serves as a buffer and pressurizing chamber for wastewater entering the device, and the pressurizing mechanism 6 increases the water pressure to provide a power source for the drive mechanism 8. The pressurizing mechanism 6 is fixed above the transfer box 4 by the second support frame 5. The pressurizing mechanism 6 is the device's "water pressure boosting unit," which uses the rotation of the spiral blades 63 to pressurize the wastewater entering the transfer box 4, generating a water flow with sufficient kinetic energy to drive the subsequent powder feeding mechanism 7. The powder dispensing mechanism 7 is used to quantitatively add various powders required for wastewater treatment into the wastewater. The powder dispensing mechanism 7 is fixed in the inner cavity of the packaging box 3. By setting up the powder dispensing mechanism 7, it serves as the "quantitative dosing unit" of the device, storing various powdered agents required for wastewater treatment, such as lime and flocculants, and automatically and quantitatively adding them into the wastewater under the action of the drive mechanism 8 to achieve chemical precipitation treatment. The drive mechanism 8 utilizes the impact force of water flow to drive the powder dispensing mechanism 7. The drive mechanism 8 is located inside the powder dispensing mechanism 7. By setting up the drive mechanism 8, it serves as the "energy conversion and transmission unit" of the device. It uses the impact force of the high-speed water flow generated by the pressurization mechanism 6 to drive the rotating frame 81 to rotate, thereby triggering the quantitative dispensing action of the powder dispensing mechanism 7, realizing automatic dosing without external power. A connecting pipe 10 runs through the upper surface of the storage tank 1. The bottom end of the connecting pipe 10 extends to the bottom of the inner cavity of the storage tank 1, and the top end of the connecting pipe 10 passes through the top of the outer surface of the transfer tank 4. A circular opening is provided on the upper surface of the storage tank 1. By setting up the connecting pipe 10, the sediment or circulating water at the bottom of the storage tank 1 is led back to the transfer tank 4 to realize wastewater recycling or sediment backflushing. The circular opening on the upper surface of the storage tank 1 serves as the discharge channel for the rotating funnel 83 below the drive mechanism 8, allowing the wastewater after mixing the reagents to fall directly into the storage tank 1.

[0022] The pressurization mechanism 6 includes a stepper motor 61 and a spray nozzle 64. The stepper motor 61 is fixed to the inner wall of the second support frame 5. A rotating rod 62 is mounted on the output end of the stepper motor 61 via a coupling. The rotating rod 62 passes through and extends into the inner cavity of the transfer box 4. A spiral blade 63 is fixed to the outer surface of the rotating rod 62. The spray nozzle 64 is fixed to the inner wall of the transfer box 4 and is located below the spiral blade 63. The stepper motor 61 serves as the rotational power source for the pressurization mechanism 6, and its speed is controllable, allowing adjustment of the spiral blade 63's speed according to the wastewater flow rate and treatment requirements. The rotating rod 62 transmits the torque of the stepper motor 61 to the spiral blade 63. As the spiral blade 63 rotates with the rotating rod 62, it generates a downward pushing force on the wastewater in the transfer box 4, increasing the wastewater pressure and flow rate. By setting a nozzle 64 below the spiral blade 63, the pressurized high-speed water flow is concentrated and sprayed onto the blades 88 of the drive mechanism 8, creating an impact force that drives the rotating frame 81 to rotate. The aperture and angle of the nozzle 64 are designed to optimize the kinetic energy conversion efficiency of the water.

[0023] The powder dispensing mechanism 7 includes a fixing ring 71, which is fixed to the inner wall of the packaging box 3. The inner ring of the fixing ring 71 is fixed to the outer surface of the transfer box 4. Three rotationally symmetrical cavities are formed on the upper surface of the fixing ring 71, and a track groove is formed on the outer surface of the fixing ring 71, which communicates with the cavities. A sliding ring 75 is slidably connected to each cavity of the fixing ring 71. The fixing ring 71 serves as the fixed base for the powder dispensing mechanism 7, with its inner ring fixed to the outer surface of the transfer box 4 and its outer ring connected to the inner wall of the packaging box 3. The three rotationally symmetrical cavities on its upper surface accommodate components such as the sliding ring 75 and spring 74, with each cavity corresponding to the dispensing of a specific agent. The track groove provides a guide channel for the vertical movement of the sliding frame 78. The sliding ring 75 slides up and down within the cavities of the fixing ring 71, driving the material-transmitting frame 76 and the conical blocking block 77 to move, thus controlling the timing and amount of agent dispensing.

[0024] A sliding frame 78 is fixed to the outer surface of the sliding ring 75. The sliding frame 78 is slidably connected to a track groove on the outer surface of the fixed ring 71. A spring 74 is fixed to the inner cavity of the sliding frame 78, and a support ring 73 is fixed to the bottom end of the spring 74. The support ring 73 is fixed to the bottom of the cavity in the fixed ring 71. By setting the sliding frame 78, the sliding ring 75 is connected to the track groove, restricting the sliding ring 75 to move only in the vertical direction and preventing deflection. By setting the spring 74, an upward restoring force is provided, keeping the sliding ring 75 in the lower limit position when no external force is applied. The conical blocking block 77 seals the discharge port of the storage tank 710 to prevent drug leakage. By setting the support ring 73, a fixed bottom support point is provided for the spring 74.

[0025] A material-permeable frame 76 is fixedly mounted at the top of the sliding frame 78, and a conical blocking block 77 is fixedly mounted at the top of the material-permeable frame 76. The powder dispensing mechanism 7 also includes three storage boxes 710, which are rotate symmetrically mounted on the inner wall of the packaging box 3. A sealing ring 711 passes through the lower surface of the storage box 710, and the sealing ring 711 is squeezed and fitted to the outer surface of the conical blocking block 77. The material-permeable frame 76 connects the sliding frame 78 and the conical blocking block 77. The material-permeable frame 76 is hollow inside, and when the conical blocking block 77 moves downward, the medicine can flow out from the side or bottom of the material-permeable frame 76. The conical blocking block 77 forms a sealing fit with the sealing ring 711 on the lower surface of the storage box 710. When the sliding ring 75 is driven upward, the conical blocking block 77 disengages from the sealing ring 711, opens the outlet, and the medicine flows out. By setting up storage tanks 710, different agents such as lime, flocculants, and coagulants can be stored separately, enabling independent storage and quantitative dosing of multiple agents. The three rotationally symmetrical storage tanks 710 correspond to three cavities, ensuring the uniformity and continuity of agent dosing.

[0026] A control valve 712 runs through the upper surface of the storage tank 710. A feed funnel 713 is fixed at the top opening of the control valve 712. The drive mechanism 8 includes a rotating frame 81, which is rotatably connected to the inner ring of the fixed ring 71. The control valve 712 controls the feeding and discharging of the storage tank 710, and the feeding speed of the medicine can be adjusted as needed. The feed funnel 713 facilitates the addition of medicine powder to the storage tank 710 by the operator. The rotating frame 81 is the rotating body of the drive mechanism 8, rotating under the impact of high-speed water flow. Its rotational motion triggers the feeding action of the powder dispensing mechanism 7.

[0027] A rolling bearing 82 is fixed to the outer surface of the rotating frame 81. The outer ring of the rolling bearing 82 is fixed to the inner ring of the fixed ring 71. Several evenly distributed material inlets are opened on the upper surface of the rotating frame 81. The material inlets on the upper surface of the rotating frame 81 are frictionally adapted to the lower surface of the fixed ring 71. A rotating funnel 83 is fixed to the lower surface of the rotating frame 81, and the rotating funnel 83 is located directly above the circular opening on the upper surface of the storage tank 1. By setting the rolling bearing 82, the rotating frame 81 is supported to rotate smoothly within the fixed ring 71, reducing frictional resistance. By setting the material inlets on the upper surface of the rotating frame 81, when the rotating frame 81 rotates, the discharge port at the bottom of the cavity of the material inlet fixed ring 71 aligns, allowing the medicine powder falling from the storage tank 710 to fall into the rotating funnel 83 below through the material inlet, realizing intermittent quantitative feeding. By setting the rotating funnel 83, as the rotating frame 81 rotates, the received medicine powder is evenly sprinkled into the circular opening on the upper surface of the storage tank 1 and mixed with wastewater.

[0028] An arched extrusion frame 84 is fixed to the side of the upper surface of the rotating frame 81, and a roller 79 is slidably connected to the inner cavity of the sliding frame 78. The outer surfaces of the arched extrusion frame 84 and the roller 79 are frictionally fitted together. By setting the arched extrusion frame 84, as the rotating frame 81 rotates, its arched surface periodically contacts and extrudes the roller 79. By setting the roller 79, which is installed in the inner cavity of the sliding frame 78, it can rotate freely, converting the rotational motion of the arched extrusion frame 84 into the vertical reciprocating motion of the sliding frame 78. When the protruding part of the arched extrusion frame 84 contacts the roller 79, it pushes the sliding frame 78 to move upward, causing the conical blocking block 77 to move upward and opening the discharge port; when the arched extrusion frame 84 disengages from the roller 79, the spring 74 pulls the sliding frame 78 to reset and close the discharge port. This design realizes the linkage between the drug dispensing and the rotation of the rotating frame 81. Each time the rotating frame 81 rotates once, each storage box 710 completes one quantitative dispensing.

[0029] A third support frame 85 is fixed to the inner wall of the rotating frame 81. A rotating column 86 is fixed to the inner wall of the third support frame 85. A rotating cone 87 is fixed to the top of the rotating column 86. Several evenly distributed drainage grooves are formed on the surface of the rotating cone 87, and several evenly distributed blades 88 are fixed to the upper surface of the rotating cone 87. By setting the third support frame 85 and the rotating column 86, the rotating cone 87 is supported at the center of the rotating frame 81. By setting the rotating cone 87, its conical surface guides the water flow downward and diffuses it, while the drainage grooves on the surface make the water flow evenly dispersed. The blades 88, fixed to the upper surface of the rotating cone 87, are the "water energy receivers" of the drive mechanism 8. The high-speed water flow sprayed by the nozzle 64 of the pressurization mechanism 6 impacts the blades 88, causing the rotating cone 87 and the rotating frame 81 to rotate as a whole, converting the kinetic energy of the water flow into mechanical rotational energy, driving the entire powder dispensing mechanism 7 to work, realizing automatic dosing without external power.

[0030] Working principle: Phosphate-containing wastewater is poured into the inner cavity of storage tank 1. Stepper motor 61 starts, driving rotating rod 62 and spiral blade 63 to rotate, pressurizing transfer box 4, increasing its pressure and flow rate. The wastewater in the inner cavity of storage tank 1 is then drawn into the inner cavity of transfer box 4 through connecting pipe 10. The pressurized high-speed water jet is sprayed downward from nozzle 64, impacting the blades 88 on the upper surface of rotating cone 87. Under the impact of the water flow, blades 88 drive rotating cone 87, rotating column 86, and rotating frame 81 to rotate as a whole. Rolling bearing 82 ensures that rotating frame 81 rotates smoothly within fixed ring 71. When the rotating frame 81 rotates, the arched extrusion frame 84 on its upper surface rotates accordingly. The protruding part of the arched extrusion frame 84 periodically contacts and extrudes the rollers 79 on the three sliding frames 78, pushing the sliding frames 78 and the sliding ring 75 to move upward. The upward movement of the sliding ring 75 causes the material passing frame 76 and the conical blocking block 77 to move upward, and the conical blocking block 77 disengages from the sealing ring 711 on the lower surface of the storage box 710, opening the discharge port.

[0031] The powdered chemicals, such as lime, flocculant, and coagulant aid, stored in the three storage bins 710 fall into the material passing frame 76 through the discharge port under gravity, and then into the rotating funnel 83 through the material passing port on the upper surface of the rotating frame 81. The rotating funnel 83 rotates with the rotating frame 81, evenly sprinkling the powdered chemicals into the round opening on the upper surface of the storage bin 1. When the arched extrusion frame 84 rotates past the roller 79, the spring 74 pulls the sliding frame 78 to reset, and the conical blocking block 77 re-seals the discharge port, completing one quantitative dosing. Each time the rotating frame 81 rotates once, each storage bin 710 completes one dosing. The amount of chemicals added is proportional to the rotation speed of the rotating frame 81 and automatically matches the water flow speed. After the powdered reagent falls into storage tank 1, it mixes thoroughly with the wastewater inside. Lime raises the pH of the wastewater, and phosphates react with calcium ions to form hydroxyapatite precipitate; flocculant causes fine precipitates to aggregate into large flocs, accelerating sedimentation. Some precipitates settle at the bottom of storage tank 1, while the supernatant is discharged through drain valve 9, achieving solid-liquid separation.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
