Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a high-efficiency flocculation and sedimentation device for wastewater treatment. Background Technology
[0002] A high-efficiency flocculation sedimentation device for wastewater treatment is a device specifically designed to separate and remove suspended particulate pollutants from wastewater, utilizing the principles of flocculation and sedimentation. This device achieves efficient wastewater treatment through the addition of flocculants, mixing, and an optimized sedimentation tank. The high-efficiency flocculation sedimentation device refers to wastewater treatment equipment that can effectively promote the aggregation of suspended particles in wastewater into larger particles within a short time and accelerate their settling to the bottom of the tank.
[0003] A typical high-efficiency flocculation sedimentation device for wastewater treatment consists of an inlet pipe, a mixing device, and a flocculation reaction tank. During operation, the inlet pipe serves as the initial channel for wastewater entry. Thanks to its pipe diameter and ingenious internal design, wastewater is introduced via inlet pressure or pumping power. In the flocculation reaction tank, the high-speed rotating blades of the mixing device strongly agitate the wastewater. The different shapes and rotation speeds of the blades create diverse water flow patterns, significantly increasing the collision frequency between the flocculant and the tiny particles in the wastewater, thus aiding in floc formation. The flocculation reaction tank is the core reaction area, where wastewater and flocculant converge. Its special structure guides a slow water flow, extending the reaction time. With the assistance of mixing, the flocculant aggregates from small particles to larger ones through charge neutralization and adsorption bridging, laying the foundation for sedimentation and separation.
[0004] However, in some existing devices, when the stirring equipment is working continuously to ensure efficient flocculation, the sedimentation zone cannot collect sediment in a synchronous and effective manner. Due to the large fluctuations in water flow caused by the stirring action, the settled sludge is easily stirred up again, interfering with the sedimentation process and resulting in a significant reduction in sedimentation effect. On the other hand, the device for collecting sediment is poorly designed and lacks a buffer adapted to the stirring conditions. Therefore, a high-efficiency flocculation sedimentation device for wastewater treatment is proposed to solve the above problems. Utility Model Content

[0033] 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.
[0034] Reference Figures 2 to 5 This utility model provides an embodiment of a high-efficiency flocculation and sedimentation device for wastewater treatment, comprising a base 1, a processing chamber 2 fixedly connected to the top of the base 1, a stirring assembly for stirring fixedly connected to the top of the processing chamber 2, the stirring assembly including a stirring motor 3, designed to provide good driving capability, the stirring motor 3 externally fixedly connected to the top of the processing chamber 2, a connecting column 4 fixedly connected to the output end of the stirring motor 3, the rotation of the stirring motor 3 can drive the connecting column 4 to rotate, multiple stirring blades 5 fixedly connected to the outside of the connecting column 4, the stirring blades 5 can stir the wastewater inside when the connecting column 4 rotates, the bottom of the connecting column 4 fixedly connected to the inside of the connecting groove 11, and a discharge assembly for discharging the settled water fixedly connected to the top of the processing chamber 2, the discharge assembly including a water injection pipe 6, designed to inject wastewater into the processing chamber 2, the bottom of the water injection pipe 6 fixedly connected to the top of the processing chamber 2. The processing chamber 2 is fixedly connected to the outside of a water outlet pipe 7. Wastewater that has been stirred can flow out from the inside of the water outlet pipe 7. The bottom wall of the processing chamber 2 is rotatably connected to a positioning ring 12, which is designed to prevent positional displacement during rotation. The top of the positioning ring 12 is fixedly connected to a collection box 8, which is designed to collect sediment inside the processing chamber 2 during rotation. The top of the collection box 8 has a connecting groove 11. The connecting groove 11 is connected to the bottom of the connecting column 4, which allows the connecting column 4 to drive the collection box 8 to rotate together. The top of the collection box 8 is fixedly connected to multiple placement rods 9, which are designed to be placed at an angle. They can collect sediment during rotation. The interior of the multiple placement rods 9 has an inclined groove 10, which is designed to facilitate the collection of sediment flowing during rotation. The top of the connecting groove 11 is fixedly connected to the bottom of the stirring assembly. The collection box 8 rotates in the same direction as the stirring assembly, so that the wastewater enters the interior of the inclined groove 10 through the placement rods 9.
[0035] Reference Figure 1 and Figure 6 The top of the processing chamber 2 is fixedly connected to a discharge port 14, which is designed to hold materials that cause sedimentation in wastewater. A telescopic rod 15 is fixedly connected to the top of the processing chamber 2, providing good telescopic capability. The telescopic rod 15 is located on the outer side of the discharge port 14. A connecting block 16 is fixedly connected to the top of the telescopic rod 15, providing good connection capability. A rotating column 17 is fixedly connected to the outside of the connecting block 16. Rotating the connecting block 16 via the telescopic rod 15 causes the rotating column 17 to rotate as well. An opening and closing plate 18 is fixedly connected to the outside of 17. Its design can control the opening and closing of the material placement. Two rolling grooves 19 are opened on the outside of the opening and closing plate 18, respectively on the top and bottom sides of the opening and closing plate 18. The rolling grooves 19 can prevent the material from getting blocked when it is put in. A discharge pipe 13 is fixedly connected to the bottom of the processing chamber 2. Its design can discharge the sediment collected inside the collection box 8. An opening and closing valve 20 is fixedly connected to the outside of the discharge pipe 13. The opening and closing valve 20 can control the discharge flow rate.
[0036] Working Principle: First, wastewater is injected into processing chamber 2 through water injection pipe 6, ensuring an appropriate water volume for subsequent treatment. Then, stirring motor 3 is turned on, driving connecting column 4 to rotate, which in turn drives multiple stirring blades 5 fixed to its exterior to rotate. This process allows the stirring blades 5 to fully stir the wastewater, promoting the reaction between flocculant and suspended particles in the wastewater to form flocs. During the stirring process, the formed sediment gradually sinks to the bottom of processing chamber 2. Since the bottom of connecting column 4 is fixed inside the connecting groove 11 of collection box 8, the collection box 8 also rotates when the connecting column 4 rotates. The inclined placement rod 9, with its inclined slot 10, effectively captures and gathers the flowing sediment during rotation, guiding it into collection box 8 for centralized storage. After the stirring process is completed, the flocculation reaction is basically finished, and the suspended solids in the wastewater are collected. At this time, the clearer treated water at the top is discharged through water outlet pipe 7. The collection box 8 works in concert to achieve integrated operation of flocculation, sedimentation, and collection, ensuring efficient and clean wastewater treatment.
[0037] When feeding materials, the discharge port 14 is used to feed materials that cause sedimentation in wastewater. When flocculant needs to be added, the opening and closing plate 18 is opened, and the material is poured from the discharge port 14 into the processing chamber 2. Next, the telescopic rod 15 is used to push or adjust the angle of the opening and closing plate 18 during the feeding process. Then, the rotating column 17 and the opening and closing plate 18 control the opening and closing of the discharge port 14. When chemicals need to be added, the connecting block 16 is moved by the telescopic rod 15, which drives the rotating column 17 to rotate, thereby opening or closing the opening and closing plate 18. The rolling groove 19 consists of two grooves designed on the opening and closing plate 18 to prevent blockage during material feeding. Subsequently, the operator adjusts the flow rate of the discharge pipe 13 by controlling the opening and closing valve 20 to discharge the sediment in the collection box 8 to a designated area for subsequent treatment or cleaning.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
