Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and more specifically, to a segmented treatment device for fluoride-containing wastewater. Background Technology

[0002] In industry, wastewater from industries such as fluoride ore mining, metal smelting, aluminum processing, coking, glass, electronics, electroplating, fertilizer, and pesticides often contains high concentrations of fluorides. If this fluoride-containing wastewater is discharged without treatment, it will seriously pollute the environment on which humans depend for survival.

[0003] Based on the above, the inventors have discovered that when treating fluoride-containing wastewater, people typically simply pass the wastewater into a large treatment tank and add calcium-containing compounds such as lime, lime slurry, or carbide slag. This causes fluoride ions to react with calcium ions to produce insoluble calcium fluoride precipitate, thereby removing fluoride ions. Although this treatment method is simple, the treatment effect is often unsatisfactory. A single treatment method can easily result in the wastewater being discharged before the calcium-containing compounds have fully reacted. Furthermore, the precipitates produced in the treatment tank are usually collected and cleaned up after the wastewater treatment is completed. However, excessive accumulation of precipitates not only easily affects the normal reaction between the wastewater and the calcium-containing compounds but also easily causes pipe blockage, affecting the efficiency of wastewater treatment. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a segmented treatment device for fluoride-containing wastewater, aiming to achieve a more practical purpose. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the present invention aims to provide a segmented treatment device for fluoride-containing wastewater. This device can add calcium-containing compounds to the reaction tank to remove fluoride ions, and, in conjunction with the reverse osmosis membrane in the filter cartridge and the activated carbon filter plate assembly in the filter tank, perform multi-stage treatment and deep purification of the fluoride-containing wastewater, greatly improving its treatment efficiency. Furthermore, the addition of a hydraulic cylinder and a horizontal adjustment frame not only ensures that the calcium-containing compounds in the material rack react fully with the wastewater, but also allows for timely removal of the precipitates after the reaction, preventing clogging of the pipes and improving treatment efficiency.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A segmented treatment device for fluoride-containing wastewater includes a mounting frame on which a reaction tank, a filter tank, and multiple filter cartridges are mounted. A booster pump is installed between the reaction tank and the filter cartridges. Hydraulic cylinders are installed at the four corners of the reaction tank, and a horizontal plate is fixedly connected between the output tops of two corresponding hydraulic cylinders. A horizontal adjustment frame is provided on the bottom surface of the horizontal plate, and a material rack is provided at the bottom of the horizontal adjustment frame. A calcium-containing compound is placed in the material rack. An activated carbon filter plate assembly is installed inside the filter tank, and a reverse osmosis membrane is installed inside the filter cartridges.

[0009] Furthermore, the inlet, outlet, and sewage outlet of the multiple filter cartridges are connected by a multi-head water distribution pipe.

[0010] Furthermore, the inlet of the booster pump is connected to the inside of the reaction tank via a connecting pipe one, and the outlet of the booster pump is connected to the multi-head water distribution pipe at the inlet of the filter cartridge via a connecting pipe two.

[0011] Furthermore, the transverse adjustment frame includes a lead screw, the two ends of which are mounted on the bottom surface of the transverse plate via bearing seats. Two movable rods are threaded around the outer circumference of the lead screw, and the bottom ends of the movable rods are fixedly connected to the outside of the material rack.

[0012] Furthermore, each of the two lead screws has a pulley fixedly connected to one end of its outer periphery, and the two pulleys are connected by a synchronous belt drive.

[0013] Furthermore, one of the lead screws is fixedly connected to the outer periphery of the other end, and a stepper motor is fixedly installed on the corresponding horizontal plate. The output shaft of the stepper motor is connected to a second gear through a coupling, and the first gear and the second gear are meshed together.

[0014] Furthermore, the top of the filter tank and the multi-head water distribution pipe on the drain end of the filter cylinder are connected by a connecting pipe, and the bottom center of the filter tank is fixed and connected to a drain pipe.

[0015] Furthermore, the activated carbon filter plate assembly consists of activated carbon filter plate one, activated carbon filter plate two, and activated carbon filter plate three, and is fixedly installed in the middle of the filter tank cavity. Activated carbon filter plate one, activated carbon filter plate two, and activated carbon filter plate three are distributed parallel to each other and at equal intervals from top to bottom.

[0016] Furthermore, one end of the reaction tank is fixed and connected to a water inlet pipe.

[0017] 3. Beneficial Effects

[0018] Compared with the prior art, the advantages of this invention are:

[0019] (1) In this scheme, calcium-containing compounds are added to the reaction tank so that most of the fluoride ions in the wastewater react with them to form calcium fluoride precipitate. At the same time, with the cooperation of the reverse osmosis membrane in the filter cartridge and the activated carbon filter plate group in the filter tank, the remaining fluoride ions are further filtered. The overall treatment operation realizes the function of multi-stage treatment and deep purification of fluoride-containing wastewater, which greatly improves the effect of fluoride-containing wastewater treatment.

[0020] (2) In this scheme, by adding a hydraulic cylinder, the material rack can be moved longitudinally, while the horizontal adjustment rack, with the cooperation of a stepper motor, gear one, gear two, pulleys, and synchronous belts, can move the material rack laterally. The overall operation can make the material rack shake in the wastewater, so that the calcium compounds in the material rack can fully react with the wastewater. At the same time, by using the hydraulic cylinder in conjunction with the material rack, the material rack can be completely lifted out of the wastewater surface, so that the sediment can be cleaned in time, avoiding the sediment from clogging the pipe and improving the treatment efficiency.

[0046] Please see Figure 1-8 A segmented treatment device for fluoride-containing wastewater includes a mounting frame 1, on which a reaction tank 2, a filter tank 3, and multiple filter cartridges 4 are mounted. A booster pump 5 is installed between the reaction tank 2 and the filter cartridges 4.

A calcium-containing compound is placed inside the material rack 9. An activated carbon filter plate assembly 10 is installed inside the filter tank 3, and a reverse osmosis membrane 11 is installed inside the filter cartridges 4.

[0047] See Figure 1 The inlet, outlet and sewage outlet of multiple filter cartridges 4 are connected by a multi-head water distribution pipe 12.

[0048] See Figure 1 and Figure 3The inlet of the booster pump 5 is connected to the inside of the reaction tank 2 through a connecting pipe 1, and the outlet of the booster pump 5 is connected to the multi-head water distribution pipe 12 at the inlet of the filter cylinder 4 through a connecting pipe 2.

[0049] See Figure 5 The horizontal adjustment frame 8 includes a lead screw 81. Both ends of the lead screw 81 are mounted on the bottom surface of the horizontal plate 7 through bearing seats. Two moving rods 82 are threaded on the outer circumference of the lead screw 81. The bottom end of the moving rods 82 is fixedly connected to the outside of the material rack 9.

[0050] See Figure 5 Each of the two lead screws 81 has a pulley 83 fixedly connected to one end of its outer periphery, and the two pulleys 83 are connected by a synchronous belt 84.

[0051] See Figure 5 and Figure 6 One of the lead screws 81 has a gear 85 fixedly connected to the outer periphery of the other end, and a stepper motor 86 is fixedly installed on the corresponding horizontal plate 7. The output shaft of the stepper motor 86 is connected to a gear 87 through a coupling. The gear 85 and the gear 87 are meshed together.

[0052] See Figure 1 and Figure 3 The top of the filter tank 3 is connected to the multi-head water distribution pipe 12 on the drain end of the filter cylinder 4 by a connecting pipe. The bottom center of the filter tank 3 is fixed and connected to the drain pipe 13.

[0053] See Figure 7 The activated carbon filter plate assembly 10 consists of activated carbon filter plate one 101, activated carbon filter plate two 102 and activated carbon filter plate three 103, and is fixedly installed in the middle of the filter tank 3. Activated carbon filter plate one 101, activated carbon filter plate two 102 and activated carbon filter plate three 103 are distributed parallel and equidistant from top to bottom. In use, the pore size of activated carbon filter plate one 101, activated carbon filter plate two 102 and activated carbon filter plate three 103 decreases in sequence.

[0054] See Figure 1 One end of the reaction tank 2 is fixed and connected to the water inlet pipe 14.

[0055] In use: Fluorine-containing wastewater is discharged into reaction tank 2 via inlet pipe 14. Then, calcium-containing compounds are placed in material rack 9. Next, hydraulic cylinder 6 is activated to lower material rack 9 until its top is slightly above the wastewater level. At this point, stepper motor 86 is activated, rotating first in the forward direction and then in the reverse direction. With the cooperation of synchronous belt 84 and pulley 83, two lead screws 81 rotate synchronously in the forward direction and then in the reverse direction. During the rotation of lead screws 81, the moving rod 82 drives the material rack 9 to move laterally back and forth in the wastewater, allowing the calcium-containing compounds inside to fully react with the fluoride ions in the wastewater. After a period of reaction... Then, the material rack 9 is lifted by the hydraulic cylinder 6 to remove the sediment and replace it with a calcium-containing compound, thereby improving the treatment effect. After the wastewater is treated in the reaction tank 2, the wastewater is pressurized again by the booster pump 5 and sent to the filter cartridge 4. The solute and solvent in the wastewater are separated by the reverse osmosis membrane 11. Finally, the wastewater is discharged into the filter tank 3, where the remaining fluoride ions are further filtered by the multi-layer filtration of the activated carbon filter plate assembly 10. Through the addition of calcium-containing compounds in the reaction tank 2, the reverse osmosis membrane 11 in the filter cartridge 4, and the multi-stage treatment of the activated carbon filter plate assembly 10 in the filter tank 3, the fluoride-containing wastewater is deeply purified, greatly improving the treatment effect of the fluoride-containing wastewater.
