[0002] Lithium iron phosphate is an important positive electrode material for ion batteries. Its production process produces a large amount of wastewater. Lithium iron phosphate wastewater mainly contains phosphoric acid, iron ions and other organic pollutants. These wastewaters cause serious pollution to the environment. Therefore, appropriate treatment processes are needed to treat lithium iron phosphate wastewater to meet emission standards. The relevant technology adds an appropriate amount of chemical agents to cause precipitation reaction between phosphoric acid and iron ions in the wastewater, thereby removing iron phosphate ions and organic pollutants in the iron phosphate wastewater.

[0003] However, there will be some problems. For example, when the existing lithium iron phosphate wastewater treatment equipment treats the wastewater, the impurities and pollutants in the wastewater will remain at the bottom of the equipment, which needs to be cleaned frequently. However, it is not convenient to clean the pollutants at the bottom of the equipment after the traditional lithium iron phosphate production wastewater treatment equipment is used, which greatly reduces the cleaning speed and use efficiency of the lithium iron phosphate production wastewater treatment equipment.

[0004] Therefore, how to provide a wastewater treatment device that reduces the difficulty of cleaning has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0034] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0035] See also Figures 1 to 3 The utility model discloses a wastewater treatment device, including a supporting frame 1, a sedimentation box 2, a clean water tank 6, a discharge structure, a protective bracket 4 and a storage box 14.

[0036] The sedimentation tank 2 is installed above the supporting frame 1. A water inlet pipe 19 is provided on one side of the upper part of the sedimentation tank 2. Two feeding ports 3 are provided on the top. A drainage structure is provided at the bottom of the sedimentation tank 2. A protective bracket 4 is fixedly connected to the side of the sedimentation tank 2. A transition pipe 5 is fixedly connected to the middle of the side wall of the sedimentation tank 2. The end of the transition pipe 5 is fixedly connected to the upper part of the clean water tank 6. The lower part of the clean water tank 6 is connected to a drain pipe 7. The transition pipe 5 and the drain pipe 7 are each provided with a water valve. Chemical agents such as precipitants and filtered sediment items can be added into the sedimentation tank 2 through the feeding port 3. The protective bracket 4 can facilitate the operator to operate the sedimentation tank 2. The treated wastewater in the sedimentation tank 2 can enter the clean water tank 6 through the transition pipe 5, and the water source in the clean water tank 6 can be discharged through the drain pipe 7.

[0037] Combination Figure 4 The side wall of the sedimentation box 2 is also fixedly connected to a water inlet pipe 19, which can be arranged on the opposite side of the transition pipe 5. The outer wall of the water inlet pipe 19 is fixedly sleeved with a protective sheet 20, which can play a sealing role; the inner wall of the water inlet pipe 19 is threadedly connected to a filter frame 21, and a filter screen 22 is fixedly connected to the water flow channel of the filter frame 21. The outer wall of the water inlet pipe 19 is threadedly connected to a connecting outer pipe 23, and a clamp is also provided at the connection between the connecting outer pipe 23 and the water inlet pipe 19. The clamp includes a fixed sleeve 24 that is movably sleeved on the outer wall of the connecting outer pipe 23, and the outer wall of the fixed sleeve 24 is fixedly connected to the installation connecting piece 25.

[0038] When using the lithium iron phosphate production wastewater treatment equipment, first, the filter frame 21 is threadedly connected to the inner wall of the water inlet pipe 19. When the wastewater enters the sedimentation tank 2 through the filter frame 21, the filter screen 22 can be used to filter the passing wastewater, thereby preventing large debris in the wastewater from entering the inner side of the sedimentation tank 2, thereby causing blockage of the internal pipe of the sedimentation tank 2, effectively improving the service life of the lithium iron phosphate production wastewater treatment equipment, and then the connecting outer tube 23 is threadedly sleeved on the outer wall of the water inlet pipe 19 to connect it to the water inlet pipe 19. Finally, the fixing sleeve 24 is sleeved on the connection between the water inlet pipe 19 and the connecting outer tube 23 and fixed by installing the connecting piece 25, which can further strengthen the connection stability between the connecting outer tube 23 and the water inlet pipe 19.

[0039] The bottom of the sedimentation tank 2 is connected to a rotatable discharge mechanism, which is installed flipably at the free end of the sewage discharge channel. In this embodiment, the discharge mechanism is a discharge hopper 13, which has an empty state with the discharge port facing upward, and a loaded state with the discharge port flipped downward; the discharge hopper 13 includes relative vertical surfaces and oblique surfaces to form a structure in which the cross section of the discharge hopper 13 gradually decreases in the direction away from the discharge port. When the discharge hopper 13 is in the loaded state, the discharge port flips to the direction where the oblique surface is located. Figure 5 The drainage port on the bottom wall of the sedimentation tank 2 is connected with a drainage pipe 9, and the other end of the drainage pipe 9 is provided with an internal thread and a threaded plug 10 with a detachable plug is threadedly connected; a drainage channel 8 is also installed on the bottom wall of the sedimentation tank 2, and the drainage channel 8 is sleeved on the outside of the drainage pipe 9, and a discharge hopper 13 is flipably installed at the free end of the drainage channel. A movable storage box 14 is provided below the discharge hopper 13, and when the discharge hopper 13 is in a loaded state, the drainage port of the discharge hopper 13 flips toward the storage box 14.

[0040] An observation window is provided on the side wall of the sewage channel 8, and the orthographic projection of the threaded plug 10 on the side wall is located in the observation window, which is convenient for the operator to remove the threaded plug 10 from the observation window; a mounting plate 11 is provided on the inner wall of the sewage channel 8, and the mounting plate 11 is used to install an elastic telescopic rod 12. The free end of the elastic telescopic rod 12 is rotatably connected to a discharge hopper 13, so that the discharge hopper 13 can be telescopically moved up and down in the sewage channel 8. When the elastic telescopic rod 12 is in the retracted state, the discharge hopper 13 is located inside the sewage channel 8. When the elastic telescopic rod 12 is in the extended state, the discharge hopper 13 can be extended into the storage box 14, and the discharge hopper 13 can be rotated around the rotation axis relative to the elastic telescopic rod 12 in the storage box 14, so as to realize the position conversion of the discharge hopper 13 between the no-load state and the loaded state. The cross section of the discharge hopper 13 gradually decreases in the direction away from the discharge port, so as to facilitate the rapid discharge of sediment into the storage box 14. The lower end of the discharge hopper 13 is smaller than the internal size of the storage box 14, so that the discharge hopper 13 can be sleeved inside the storage box 14. It should be noted that the cross section of the discharge hopper 13 gradually decreases in the direction away from the discharge port and is rotatably connected to one end of the elastic telescopic rod 12, resulting in an unstable center of gravity. If the material continues to increase, the discharge hopper 13 will tilt in the storage box 14, thereby dumping the sediment into the storage box 14.

[0041] A space is reserved below the supporting frame 1 for placing a material storage box 14. The movable material storage box 14 can be moved to the bottom of the discharge hopper 13. The material storage box 14 is fixed on a sliding base plate 15 serving as a sliding mechanism. The sliding base plate 15 can be pulled out and installed on a base with a slide rail 16. A portable pull rod 17 can be provided at the pulling end of the sliding base plate 15, and a pulley 18 in contact with the ground can be provided at the bottom of the sliding base plate 15.

[0042] The bottom of the discharge pipe 9 is located above the storage box 14. By removing the threaded plug 10 from the discharge pipe 9, the impurities and pollutants at the bottom of the sedimentation box 2 can enter the inner side of the sewage discharge channel 8 through the discharge pipe 9, and then pour into the interior of the storage box 14 through the discharge hopper 13. Finally, the sliding bottom plate 15 can be pulled out from the inner side of the slide rail 16 by the portable pull rod 17, driving the storage box 14 at the upper end of the sliding bottom plate 15 to separate from the bottom of the sedimentation box 2, so that the debris inside the storage box 14 can be cleaned. The operation is simple, fast and effective to improve the cleaning speed and use efficiency of the lithium iron phosphate production wastewater treatment equipment. Finally, the storage box 14 is pushed into the bottom of the sedimentation box 2. , since the discharge hopper 13 can freely extend and retract inside the sewage channel 8 by means of the elastic telescopic rod 12, when the storage box 14 touches the bottom of the discharge hopper 13, the discharge hopper 13 will shrink toward the inside of the sewage channel 8 (move upward), and when the storage box 14 moves to the bottom of the discharge hopper 13, the discharge hopper 13 will use the elastic force of the elastic telescopic rod 12 to quickly sleeve on the inside of the storage box 14 (move downward), and the discharge port of the discharge hopper 13 under the load state is flipped toward the inside of the storage box 14, so that the pollutants at the bottom of the sedimentation box 2 can fall into the inside of the storage box 14 through the discharge hopper 13, making it convenient to clean them.

[0043] In summary, the wastewater treatment equipment provided by the utility model is provided with a water inlet pipe and a feeding port 3 on the upper part of the sedimentation tank 2. After the wastewater to be treated enters the sedimentation tank 2, chemical agents can be added through the feeding port 3 to cause a precipitation reaction between the phosphate and the iron ions in the wastewater. After the precipitation reaction occurs, the precipitate is deposited at the bottom of the sedimentation tank 2, and the treated clean water is located at the upper part of the sedimentation tank 2. After the clean water is discharged from the transition pipe 5 to the clean water tank 6, the precipitate at the bottom can be discharged from the discharge pipe 9 to the discharge hopper 13. After the precipitate in the discharge hopper 13 accumulates to a certain weight, the discharge port of the discharge hopper 13 is turned toward the inside of the storage box 14, and the precipitate is poured into the storage box 14. When the storage box 14 has collected all the precipitate, the storage box 14 is removed from the bottom of the sedimentation tank 2 to complete the collection of the precipitate. The wastewater treatment equipment of the utility model can discharge sediments through the discharge structure at any time, and remove the sediments through the storage box 14 to prevent the sediments from piling up at the bottom of the sedimentation box 2, thereby improving the cleaning speed and use efficiency of the lithium iron phosphate production wastewater treatment equipment. The elastic telescopic rod 12 can play the role of telescopic up and down. When the storage box 14 moves to the lower end of the discharge hopper 13, the staff will swing the discharge hopper 13 upward to shrink the elastic telescopic rod 12, and then the storage box 14 can be moved to the bottom of the discharge hopper 13 to receive the material. If the storage box 14 is simply moved to the bottom of the discharge hopper 13 and is not sleeved, the discharge hopper 13 may cause pollutants to spray out due to the large impact when discharging. When transferring the storage box 14, the discharge hopper 13 is also moved upward to shrink the elastic telescopic rod 12. At this time, the storage box 14 can be moved out through the portable pull rod 17.
