Description

Technical Field

[0001] This application relates to the field of wastewater treatment, and in particular to a magnetic flocculation microfiltration wastewater defluorination device with dynamic magnetic seed dispensing. Background Technology

[0002] Currently, many industries, such as iron smelting, phosphate rock processing, phosphate fertilizer production, and coal combustion, produce emissions containing large amounts of fluoride ions, resulting in industrial wastewater containing fluoride. Therefore, this wastewater must undergo defluorination treatment before discharge to prevent fluoride ions from polluting water bodies.

[0003] Existing methods for treating fluoride ions often utilize magnetic flocculation microfiltration equipment. This equipment combines magnetic flocculation and microfiltration technologies, primarily used to remove suspended solids, colloids, organic matter, and some microorganisms from water. Magnetic flocculation microfiltration equipment includes a magnetic seeding tank, a microfiltration tank, and a magnetic separation system. The magnetic seeding tank is used to add and mix magnetic seeds. The microfiltration tank filters the magnetic seed flocs. The magnetic separation system separates the impurities filtered by the microfiltration tank. The separated magnetic seeds are then returned to the magnetic seeding tank for reuse.

[0004] The existing technical solutions mentioned above have the following drawbacks: the flow rate of wastewater entering the magnetic seed addition tank varies with the production speed. The existing magnetic seeds are basically added in quantitative quantities. In order to avoid the increased cost caused by over-addition of magnetic seeds, the magnetic seeds are generally added according to a lower standard, which leads to insufficient magnetic seeds and reduces the magnetic flocculation effect.

[0030] Reference Figure 2 and Figure 3 An impeller 5 and an output shaft 6 are installed inside the inlet pipe 2. The impeller 5 is rotatably connected to the inlet pipe 2. The wastewater flowing through the inlet pipe 2 drives the impeller 5 to rotate. In this embodiment, in order to increase the rotational speed of the impeller 5, the wastewater in the inlet pipe 2 can be pressurized and transported by a booster pump. The impeller 5 is fixedly connected to the output shaft 6. The impeller 5 drives the output shaft 6 to rotate. A linkage device 7 is provided between the output shaft 6 and the dispensing device 4. The linkage device 7 is used to control the dispensing speed of the dispensing device 4.

Both the output shaft 6 and the stirring shaft 81 are rotatably connected to the transmission box 91.

[0032] Reference Figure 2 and Figure 4 In this embodiment, in order to deliver the magnetic seeds more evenly into the liquid in the pool 1, the delivery pipe 44 is positioned centrally between the partition 30 and the inlet pipe 2. The stirring shaft 81 is coaxially arranged with the delivery pipe 44 for more even stirring. Therefore, the transmission box 91 is located directly below the delivery pipe 44 for better transmission. Thus, in this embodiment, a distribution cone 911 is provided at the top of the transmission box 91. The distribution cone 911 is conical, with its tip pointing upwards and directly facing the outlet of the delivery pipe 44. The distribution cone 911 is used to evenly distribute the magnetic seeds delivered by the delivery device 4 around the stirring shaft 81. After the magnetic seeds enter the pool 1 through the delivery pipe 44, the stream of magnetic seeds comes into contact with the distribution cone 911 and is evenly dispersed into an umbrella-shaped spray surface, so that the magnetic seeds are evenly distributed over a large area when added, thereby making it easier to mix the magnetic seeds and wastewater evenly.

[0033] Reference Figure 4The stirring shaft 81 includes an inner rod 811 and a rotating sleeve 812. One end of the inner rod 811 is fixedly connected to the tank body 1, and the other end is fixedly connected to the transmission box 91. The rotating sleeve 812 is sleeved on the outside of the inner rod 811 and is rotatably connected to the inner rod 811. The rotating sleeve 812 is fixedly connected to the second bevel gear 922.

The stirring rod 82 is rotatably connected to the rotating sleeve 812. A follower cavity is opened on the rotating sleeve 812. The follower gear set 10 is located in the follower cavity. The follower gear set 10 is used to drive the stirring rod 82 to rotate around its own axis when the rotating sleeve 812 rotates. The follower gear set 10 includes a third bevel gear 101 and a fourth bevel gear 102. The third bevel gear 101 is fixedly connected to the inner rod 811, and the fourth bevel gear 102 is fixedly connected to the stirring rod 82.

[0034] Reference Figure 3 A support device 20 is provided between the transmission box 91 and the water inlet pipe 2. The support device 20 includes a support frame 201 and a support rod 202. The support frame 201 is sleeved on the outside of the output shaft 6. The output shaft 6 is rotatably connected to the support frame 201. Several support rods 202 are provided. The two ends of the support rods 202 are fixedly connected to the support frame 201 and the pool body 1, respectively.

[0035] The implementation principle of the magnetic flocculation microfiltration wastewater defluorination device with dynamic magnetic seed delivery in this application embodiment is as follows: When using the device, the magnetic seeds are first placed into the feeding hopper 41, and then high-pressure water is injected into the tank 1 through the water inlet pipe 2. The water flow encounters the impeller 5, which drives the output shaft 6 to rotate. The rotation of the output shaft 6 drives the drive wheel 71 to rotate. The rotation of the drive wheel 71 drives the driven wheel 72 to rotate through the belt 73. The rotation of the driven wheel 72 drives the central shaft 431 of the auger 43 to rotate. The central shaft 431 drives the auger 43 to rotate, thereby conveying the magnetic seeds at the position of the feeding hopper 41 to the delivery pipe 44 in the conveying cylinder 42. The magnetic seeds fall into the tank 1 through the delivery pipe 44. After the magnetic seed beam comes into contact with the distribution cone 911, the magnetic seed beam impacts the distribution cone 911 and disperses the magnetic seeds into an umbrella shape. The magnetic seeds are evenly dispersed around the stirring shaft 81. When the output shaft 6 rotates, it drives the first bevel gear 921 to rotate, which in turn drives the second bevel gear 922 to rotate. The second bevel gear 922 then drives the rotating sleeve 812 to rotate. As the rotating sleeve 812 rotates, it rotates relative to the inner rod 811. At this time, through the meshing of the third bevel gear 101 and the fourth bevel gear 102, the rotating sleeve 812 pushes the stirring rod 82 to rotate around its own axis. The rotation of the stirring rod 82 drives the stirring block 83 to rotate, so that the stirring block 83 and the stirring rod 82 simultaneously and evenly stir the magnetic seeds and wastewater. This allows the evenly stirred water to flow through the channel between the partition 30 and the bottom wall of the tank 1 to the outlet pipe 3, and finally to be output through the outlet pipe 3 to the sedimentation tank for subsequent electromagnetic sedimentation. In summary, by setting up the linkage device 7 and the transmission device 9, the water flow speed is correlated with the magnetic seed dispensing speed and the stirring speed, thus achieving the purpose of dynamically adjusting the magnetic seed dispensing to improve the magnetic flocculation effect.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
