Description

Technical Field

[0001] This utility model relates to the technical field of integrated water purification devices, and in particular to an integrated multi-stage flocculation sedimentation water purification device. Background Technology

[0002] Sedimentation is a traditional solid-liquid separation technology, widely used in water purification both domestically and internationally. Its principle is that solid suspended matter, denser than water, naturally settles under gravity, thus separating from the water. Loaded flocculation technology belongs to heterogeneous nucleation, which involves adding high-density, insoluble particulate media to the water, utilizing the media's gravitational settling properties to accelerate floc formation and promote sedimentation.

[0003] The existing integrated multi-stage flocculation sedimentation water purification device consists of an inlet system (introducing sewage through an inlet pipe), a dosing system (for adding flocculants), a mixing and reaction system (using a stirring device to promote the reaction between the chemicals and the sewage), a sedimentation system (achieving solid-liquid separation), and an outlet system (discharging purified water).

[0004] While existing integrated multi-stage flocculation sedimentation water purification devices can meet most needs, insufficient mixing during use leads to uneven mixing of wastewater and flocculant, slow reaction speed, and reduced purification effect. Furthermore, the sludge in the reprocessing equipment requires regular manual cleaning and transportation, which is labor-intensive and prone to secondary pollution. Therefore, an integrated multi-stage flocculation sedimentation water purification device is proposed to solve the above problems. Utility Model Content

[0034] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of an integrated multi-stage flocculation sedimentation water purification device, comprising a housing 11 and a platform 27. Housing 11 serves as the main site for the flocculation reaction, where wastewater and flocculant are mixed and reacted, laying the foundation for subsequent purification. A housing 23 is fixedly connected to the outside of housing 11, and a housing 35 is fixedly connected to the outside of housing 23. Housing 315 serves as a deep purification zone, further settling sludge to achieve the required water quality. A grid 28 is fixedly connected inside housing 213, serving as a primary filtration and sedimentation zone, receiving water from housing 11. The grid 28 is used for filtration and bottom sedimentation. After removing some impurities, inclined tube 17 is installed inside the third chamber 15. Inclined tube 17 is used for a second filtration inside the third chamber 15. The structure of inclined tube 17 increases the sedimentation area, making it easier for flocs to separate from water and facilitating floc settling. An inlet pipe 12 is fixedly connected to the outside of the first chamber 11. The inlet pipe 12 serves as the channel for sewage to enter the device, introducing the sewage to be treated into the interior of the first chamber 11. An outlet pipe 14 is fixedly connected to the outside of the third chamber 15. The outlet pipe 14 discharges the purified water that meets the purification standards from the third chamber 15, serving as the output channel for the treated water. A stirring mechanism is installed inside the first chamber 11. Cleaning components are installed at the bottom of the second chamber 13 and the third chamber 15.

[0035] The stirring mechanism includes a drive assembly and a stirring assembly. The drive assembly includes a housing 2, which is fixedly connected to the top of a box 11. An internal gear 6 is installed inside the housing 2. A motor 1 is fixedly connected to the top of the housing 2. The housing 2 connects the motor 1 and the box 11 and also prevents the internal structure of the housing 2 from shifting during operation. A bracket 4 is fixedly connected to the output end of the motor 1. Multiple connecting rods 3 are fixedly connected to the bottom of the bracket 4. Gear 5 is fixedly connected to the bottom of each connecting rod 3. The internal gear 6 provides a meshing track for gear 5, restricting the movement trajectory of gear 5 and ensuring the orderly operation of the transmission system. Gear 5 and motor 1 are connected through the connecting rods 3, transmitting the rotational motion of motor 1 to gear 5 to achieve power transmission. The internal gear 6 meshes with gear 5. A second gear 7 is rotatably connected inside the housing 2. Gear 5 and gear 7 mesh with each other. The gear 5, driven by the connecting rod 3, rotates within the internal gear 6, simultaneously driving the gear 7, thus distributing power and regulating speed. A drain pipe 29 is fixedly connected between the two housings 13 and 15. The drain pipe 29 is used to introduce water from inside the two housings 13 into the three housings 15. The stirring assembly includes a rotating shaft 30, which receives power from the gear 5 via the gear 7 and transmits it to the rotating shaft 30. The rotating shaft 30 is fixedly connected to the bottom of the gear 7. A stirring rod 9 is fixedly connected to the outside of the rotating shaft 30. The rotating shaft 30 connects the gear 7 and the stirring rod 9, transmitting the rotational motion of the gear 7 to the stirring rod 9, driving it to rotate. The stirring rod 9 is rotatably connected to the middle of the one housing 11. The stirring rod 9 rotates within the one housing 11, stirring the wastewater and flocculant, accelerating their mixing reaction and improving reaction efficiency.

[0036] Reference Figure 1 , Figure 3 and Figure 4The cleaning assembly includes a connecting pipe 20, which is fixedly connected to the bottom of housings 13 and 15. A sludge tank 21 is installed at the other end of the connecting pipe 20. The sludge tank 21 is used to temporarily store the collected sludge for subsequent dewatering. The connecting pipe 20 connects housings 13 and 15 to the sludge tank 21, serving as the channel for transporting sludge from the sedimentation zone to the sludge tank 21. A water pump 18 is fixedly connected to the top of the sludge tank 21, providing power for sludge transport. By pressurizing, the sludge at the bottom of housings 13 and 15 is transported to the sludge tank 21. A connecting pipe 23 is installed on the outside of the sludge tank 21. A filter plate 22 is installed on the top of the platform 27. The sludge in the sludge tank 21 is transported to the filter plate 22 via the connecting pipe 23, realizing the transfer of sludge from storage to the dewatering stage. A feed pipe 24 is fixedly connected to one side of the filter plate 22, which is used to connect the filter plate 22 and the connecting pipe 23. A pressing plate 19 is slidably connected to the other side of the filter plate 22. The pressing plate 19 applies pressure to the sludge in the filter plate 22 to achieve sludge dewatering and drying, and reduce the sludge volume. The connecting pipe 23 is fixedly connected to one end of the feed pipe 24. A collection box 25 is installed on the inner side of the support leg 26. The collection box 25 is used to collect the sludge blocks after the filter plate 22 is dewatered, which is convenient for centralized treatment and transportation. The platform 27 makes it easy for the sludge blocks in the filter plate 22 to fall into the collection box 25. It also provides convenience for the filter plate 22 and the pressing plate 19 during operation. The collection box 25 is located at the bottom of the filter plate 22. A valve 8 is installed in the middle of the connecting pipe 20. The valve 8 controls the flow rate inside the connecting pipe 20. The valve 8 is located at the outlet end of the connecting pipe 20.

[0037] Reference Figure 1 - Figure 3 The top of the box 11 is equipped with a dosing hopper 10, which is used to add flocculant and is the inlet for the agent to enter the treatment system, making it easy to control the amount of flocculant added. The bottom of the box 3 15 is fixedly connected with a support leg 16, which is used to support the box 3 15. The bottom of the support leg 16 is flush with the bottom of the box 11, which plays a supporting role. The bottom of the platform 27 is fixedly connected with multiple support legs 26, which are used to support the platform 27.

[0038] Working principle: First, wastewater is introduced into the tank 11 through inlet pipe 12. Then, flocculant is added through dosing hopper 10. Motor 1 is then started, driving bracket 4, which in turn controls the rotation of connecting rod 3. Connecting rod 3 then drives gear 5, which rotates inside internal gear 6. This rotation of gear 5 drives gear 7, which in turn controls the rotation of shaft 30. Simultaneously, shaft 30 rotates, driving stirring rod 9, thus rapidly agitating the wastewater and flocculant inside tank 11, accelerating the reaction rate. When the water level inside tank 11 reaches a certain threshold... When the water reaches a certain height, it will flow into the interior of the second chamber 13. The water inside the second chamber 13 will be filtered for the first time through the grille 28. When there is sludge in the water inside the second chamber 13, the sludge will settle to the bottom of the second chamber 13. When the water in the second chamber 13 reaches the drain pipe 29, the water in the second chamber 13 will flow into the interior of the third chamber 15 through the drain pipe 29. Similarly, the sludge inside the third chamber 15 will settle to the bottom of the third chamber 15. The water will be filtered for the second time through the inclined pipe 17, thus meeting the standard for purified water. When the water inside the third chamber 15 reaches a certain water level, the purified water will flow out through the outlet pipe 14.

[0039] When it is necessary to treat the sludge at the bottom of tank 13 and tank 15, the water pump 18 can be started. Under the pressure of the water pump 18, the sludge at the bottom of tank 13 and tank 15 will enter the sludge tank 21 through the connecting pipe 20. The sludge in the sludge tank 21 will then enter the filter plate 22 through the connecting pipe 23. At this time, the pressing plate 19 will be started, and the pressing plate 19 will squeeze the sludge inside the filter plate 22. When the sludge is squeezed to a certain extent, the pressing plate 19 will detach from the filter plate 22, and the sludge on the filter plate 22 will fall into the collection box 25. This simplifies the sludge treatment process, facilitates management and operation, and improves the overall operation and management efficiency of the water purification device.
