[0002] MBR technology is an efficient water treatment technology that combines biological treatment and membrane filtration technology to remove suspended solids, organic matter and other pollutants in water. Etching, cleaning and other processes will produce fluoride-containing wastewater. When fluoride-containing wastewater is used, it is usually necessary to pre-treat the wastewater before deep treatment using the MBR system to reduce the fluoride ion concentration to a range that the MBR system can handle. Pretreatment methods may include chemical precipitation, etc.

[0003] The chemical precipitation process of the existing device is to add lime milk and other reagents to the fluorine-containing wastewater to make fluoride ions and calcium ions form CaF2 precipitation and remove it. However, after treatment by this method, the precipitate produced by the fluorine-containing wastewater precipitates slowly and the precipitate is difficult to dehydrate, which makes the precipitation effect of the fluorine-containing wastewater not good enough.

A speed reduction mechanism is provided on the fixing frame 3, and a switching mechanism is provided on the fixing frame 3. The switching mechanism is used to switch the discharge port. An auxiliary mechanism is provided in the sedimentation box 4, and the auxiliary mechanism is used to assist impurity precipitation.

[0030] The deceleration mechanism includes a motor bracket 5, a driving motor 6 and a reduction box 7. The motor bracket 5 is connected to one side of the fixed frame 3 by bolts, and the driving motor 6 is connected to the motor bracket 5 by bolts. The reduction box 7 is fixedly connected to one side of the fixed frame 3. The reduction box 7 is used for reducing speed and increasing torque. The reduction box 7 is provided with an input end and an output end.

[0031] The switching mechanism includes a guide rod 81, a partition plate 82, a reset spring 83, a connecting plate 84, a guide frame 85 and a push rod 86. Two guide rods 81 are welded to the lower end of the fixed frame 3. A partition plate 82 is slidably connected to the two guide rods 81.

[0032] The partition plate 82 is used to separate the two flow guide frames 85 .

[0033] The auxiliary mechanism includes a mounting block 91, an electric push rod 92, a push rod 93 and an extrusion net 94. Two mounting blocks 91 are welded on the upper outer side of the sedimentation box 4. Each mounting block 91 is connected to an electric push rod 92 by bolts. A push rod 93 is fixedly connected to the telescopic rod of each electric push rod 92. The two push rods 93 are slidably connected to the sedimentation box 4. An extrusion net 94 is slidably connected between the lower parts of the two push rods 93. The extrusion net 94 is located inside the sedimentation box 4.

[0034] At first, the staff opens the electromagnetic valve 2 42, and then the staff first adds the electronic waste water into the sedimentation box 4, and then the staff adds the reagent into the sedimentation box 4. The water level in the sedimentation box 4 is below the extrusion net 94. Finally, the staff starts the drive motor 6 and closes the electromagnetic valve 2 42. The drive motor 6 will reciprocate slightly. The output shaft of the drive motor 6 will drive the sedimentation box 4, the electromagnetic valve 1 41, the electromagnetic valve 2 42, the push rod 86, the mounting block 91, the electric push rod 92, the lower pressure rod 93 and the extrusion net 94 to swing slightly through the deceleration and torque increase of the reduction box 7. The swing of the sedimentation box 4 will fully mix the electronic waste water and the reagent in the sedimentation box 4. The electronic waste water and the reagent are fully mixed. The mixture of electronic waste water and medicine will form a mixed liquid. The mixture of electronic waste water and medicine will cause the mixed liquid to produce sediment. After the electronic waste water and medicine are mixed, the staff turns off the drive motor 6 and waits for the mixed liquid in the sedimentation box 4 to calm down. A small part of the sediment will fall to the bottom of the sedimentation box 4, and most of the sediment will float in the mixed liquid. The staff starts the electric push rod 92. The telescopic rod of the electric push rod 92 moves downward to drive the pressing rod 93 and the squeezing net 94 to move downward. The squeezing net 94 moves downward to contact the mixed liquid. The squeezing net 94 continues to move downward in the mixed liquid. The squeezing net 94 will push the sediment floating in the mixed liquid to move downward.

The movement of the partition plate 82 will drive the connecting plate 84 and the two guide frames 85 to move. The staff will open the solenoid valve 2 42, and the mixed liquid at the lower end of the sedimentation box 4 will flow into one of the guide frames 85, and then the mixed liquid will flow into the collection frame 1 installed with the MBR membrane plate 2 through one of the guide frames 85. The mixed liquid will be filtered by the MBR membrane plate 2, and then flow to the next step from the discharge hole of the collection frame 1. After the mixed liquid in the sedimentation box 4 is emptied, the staff will close the solenoid valve 2 42 and start the electric push rod 92. The electric push rod 92 will drive the lower pressure rod 93 and the extrusion net 94 to reset a short distance, and then the staff will close the electric push rod 92 and start the drive motor 6.The output shaft of the driving motor 6 will drive the sedimentation box 4, the electromagnetic valve 1 41, the electromagnetic valve 2 42, the push rod 86, the mounting block 91, the electric push rod 92, the lower pressure rod 93 and the extrusion net 94 to reverse and reset through the reduction box 7. The push rod 86 will be out of contact with the partition plate 82 when it is reversed and reset. The partition plate 82, the connecting plate 84 and the guide frame 85 will be reset under the drive of the reset spring 83. Then the staff will turn off the driving motor 6 and open the electromagnetic valve 1 41. The sediment in the sedimentation box 4 will be discharged through the electromagnetic valve 1 41. The discharged sediment will fall on another guide frame 85, and then flow through another guide frame 85 to the collection frame 1 where the MBR membrane plate 2 is not installed. After the sediment is discharged, the staff will start the electric push rod 92. The telescopic rod of the electric push rod 92 will drive the extrusion net 94 to reset. After the extrusion net 94 is reset, the staff will close the electromagnetic valve 1 41, start the electromagnetic valve 2 42 and close the electric push rod 92.

[0035] Embodiment 2: Based on embodiment 1, Figure 6-Figure 7 As shown, a reset mechanism is also included, which includes a fixed block 101, an elastic plate 102 and a clamping block 103. Two fixed blocks 101 are welded on the upper end of the sedimentation box 4, and four elastic plates 102 are welded on the extrusion net 94. Two elastic plates 102 form a group, and a clamping block 103 is welded on each elastic plate 102.

[0036] It also includes a vibration mechanism, which includes a perforated block 104 and a connecting spring 105. The lower end of each lower pressure rod 93 is welded with a perforated block 104, and each perforated block 104 is provided with a bayonet. Two connecting springs 105 are fixedly connected between two lower pressure rods 93 and an extrusion net 94, and the two connecting springs 105 are respectively located in the two lower pressure rods 93.

[0037] The downward movement of the pressing rod 93 and the squeezing net 94 will drive the elastic plate 102, the block 103, the perforated block 104 and the connecting spring 105 to move downward. The squeezing net 94 will stop moving when it contacts the bottom of the sedimentation box 4, causing the elastic plate 102 and the block 103 to stop moving. The downward movement of the pressing rod 93 will drive the perforated block 104 to move downward. The downward movement of the perforated block 104 will compress the connecting spring 105. The connecting spring 105 will cause the squeezing net 94 to apply pressure to the sediment, thereby better fixing the sediment at the bottom of the sedimentation box 4. At the same time, the perforated block 104 will stop moving. 04 moves downward, squeezing the card block 103 to make the card block 103 move, and the movement of the card block 103 will cause the elastic plate 102 to deform, and the perforated block 104 continues to move downward, and the card block 103 is out of contact with the perforated block 104, and the elastic plate 102 resets to drive the card block 103 to reset, and the card block 103 resets and is stuck in the bayonet of the perforated block 104, and then the precipitation box 4 rotates to drive the fixed block 101, the elastic plate 102, the card block 103, the perforated block 104 and the connecting spring 105 to rotate, and the precipitation box 4 and the extrusion net 94 rotate so that the sediment is on the top, and the The connecting spring 105 will apply pressure to the sediment through the squeezing net 94, and the squeezing net 94 will squeeze out the water in the sediment, thereby making the sedimentation effect better. After the sedimentation box 4 rotates, the solenoid valve 42 starts to discharge the mixed liquid. After the mixed liquid is discharged, the rotation of the sedimentation box 4 will drive the fixed block 101, the elastic plate 102, the block 103, the perforated block 104 and the connecting spring 105 to reverse and reset, and then the lower pressure rod 93 and the squeezing net 94 will reset to drive the elastic plate 102, the block 103, the perforated block 104 and the connecting spring 105 to reverse and reset upward. The block 103 moves upward and contacts with the fixed block 101. The block 103 continues to move upward, which makes the fixed block 101 push the block 103 to move. The movement of the block 103 drives the elastic plate 102 to bend, and the movement of the block 103 will be out of contact with the opening block 104. The extrusion net 94, the elastic plate 102 and the block 103 are quickly reset under the drive of the connecting spring 105. The rapid reset of the extrusion net 94 will generate vibration. The vibration of the extrusion net 94 will shake off the sediment remaining on the extrusion net 94, and the shaken sediment will flow out through the solenoid valve 41.

[0038] Embodiment 3: Based on embodiment 2, Figure 8-Figure 10 As shown, a scraping mechanism is also included, which includes an electric ring 111, a rotating ring 112, a strong magnet 113 and a scraper 115. The electric ring 111 is connected to the sedimentation box 4 by bolts, the rotating ring 112 is fixedly connected to the electric ring 111, and the strong magnet 113 is connected to the rotating ring 112 by bolts. The bottom of the sedimentation box 4 is rotatably connected to the scraper 115, and the scraper 115 is made of steel. The scraper 115 and the strong magnet 113 are attracted to each other.

[0039] The scraper 115 is used to separate the sediment.

[0040] When the sedimentation box 4 swings, the staff starts the electric ring 111, the electric ring 111 will drive the rotating ring 112 to rotate, the rotating ring 112 will drive the strong magnet 113 to rotate, the strong magnet 113 will drive the scraper 115 to rotate through magnetic force, the rotation of the scraper 115 will stir the electronic waste water and the medicine, so that the electronic waste water and the medicine are mixed more fully, the sedimentation box 4 stops swinging, the staff turns off the electric ring 111, the rotating ring 112, the strong magnet 113 and the scraper 115 stop moving; when the squeezing net 94 assists the sedimentation, the squeezing net 94 moves downward and contacts with the scraper 115; after the mixed liquid is discharged, the staff starts the electric push rod 92, the electric push rod 92 will drive the lower pressure rod 93 and the squeezing net 94 to reset upward for a short distance, The extrusion net 94 is disengaged from the scraper 115, and then the staff closes the electric push rod 92 and starts the electric ring 111. The electric ring 111 drives the rotating ring 112 and the strong magnet 113 to rotate. The rotation of the strong magnet 113 drives the scraper 115 to rotate through magnetic force. Since the extrusion net 94 is reset upward for a short distance, the scraper 115 rotates and scrapes the sediment squeezed by the extrusion net 94, so that the sediment is disengaged from the sedimentation box 4 and the extrusion net 94. The staff closes the electric ring 111, and the rotating ring 112, the strong magnet 113 and the scraper 115 stop moving. When the sediment is discharged, after the discharge solenoid valve 41 is opened, the sediment separated from the sedimentation box 4 and the extrusion net 94 falls into the guide frame 85 through the solenoid valve 41, so that the sediment is better discharged.
