An MBR membrane-based electronic wastewater sedimentation treatment device

Abstract

This invention relates to the field of wastewater treatment, and more particularly to a sedimentation treatment device for electronic wastewater based on an MBR membrane. Existing devices result in slow sedimentation of precipitates from fluoride-containing wastewater, and the precipitates are difficult to dehydrate, leading to insufficient sedimentation efficiency. The proposed MBR membrane-based electronic wastewater sedimentation treatment device includes collection frames, MBR membrane plates, and a fixing frame. Each collection frame has a discharge hole, and two collection frames are fixedly connected to a common fixing frame. Three MBR membrane plates are fixedly connected to one of the collection frames. The downward movement of the telescopic rod of the electric pusher causes the pressure rod and the squeezing screen to move downwards. The squeezing screen, moving downwards, comes into contact with the mixed liquid. As it continues to move downwards within the mixed liquid, the squeezing screen pushes the floating precipitates in the mixed liquid downwards, assisting in faster sedimentation and thus improving the sedimentation effect.

Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, and more particularly to an electronic wastewater sedimentation treatment device based on an MBR membrane. Background Technology

[0002] MBR (Membrane Bioreactor) technology is a highly efficient water treatment technology that combines biological treatment with membrane filtration to remove suspended solids, organic matter, and other pollutants from water. Processes such as etching and cleaning generate fluoride-containing wastewater. Before using an MBR system for advanced treatment of this wastewater, pretreatment is usually required to reduce the fluoride ion concentration to a level that the MBR system can handle. Pretreatment methods may include chemical precipitation.

[0003] The existing chemical precipitation process involves adding lime slurry and other agents to the fluoride-containing wastewater to cause fluoride ions to react with calcium ions to form CaF2 precipitate, which is then removed. However, after treatment, the precipitate formed by the fluoride-containing wastewater settles slowly and is difficult to dehydrate, resulting in an unsatisfactory precipitation effect. Summary of the Invention

[0004] To overcome the shortcomings of existing devices that cause slow sedimentation of precipitates from fluoride-containing wastewater and difficulty in dehydrating the precipitates, resulting in poor sedimentation effects, this invention provides an MBR membrane-based electronic wastewater sedimentation treatment device that enables faster sedimentation and removal of moisture from the precipitates, thereby achieving better sedimentation results.

[0005] Technical Solution: An electronic wastewater sedimentation treatment device based on MBR membrane includes a collection frame, MBR membrane plates, a fixing frame, a sedimentation tank, a solenoid valve one, a solenoid valve two, a reduction mechanism, a switching mechanism, and an auxiliary mechanism. Each collection frame has a discharge port, and a fixing frame is fixedly connected to two collection frames. Three MBR membrane plates are fixedly connected in one of the collection frames. The sedimentation tank is rotatably connected to the upper part of the fixing frame. Solenoid valve one is fixedly connected to the bottom of the sedimentation tank, and solenoid valve two is fixedly connected to the top of the sedimentation tank. The fixing frame is equipped with a reduction mechanism and a switching mechanism for switching the discharge port. An auxiliary mechanism is provided inside the sedimentation tank to assist in the sedimentation of impurities.

[0006] Furthermore, it is particularly preferred that the reduction mechanism includes a motor bracket, a drive motor, and a reduction gearbox. The motor bracket is fixedly connected to one side of the fixed frame, the drive motor is fixedly connected to the motor bracket, and the reduction gearbox is fixedly connected to one side of the fixed frame. The reduction gearbox has an input end and an output end. The input end of the reduction gearbox is fixedly connected to the output shaft of the drive motor, and the output end of the reduction gearbox is fixedly connected to the sedimentation tank.

[0007] Furthermore, it is particularly preferred that the switching mechanism includes guide rods, a partition plate, a return spring, a connecting plate, a flow guide, and a push rod. Two guide rods are fixedly connected to the lower end of the fixed frame, and a partition plate is slidably connected to both guide rods. Two return springs are connected between the partition plate and the fixed frame. A connecting plate is fixedly connected to the bottom of the partition plate, and two flow guides are fixedly connected to the connecting plate. Two push rods are fixedly connected to the top of the sedimentation tank.

[0008] Furthermore, it is particularly preferred that the partition plate is used to separate the two air guides.

[0009] Furthermore, it is particularly preferred that the auxiliary mechanism includes mounting blocks, electric push rods, pressing rods, and extrusion screens. Two mounting blocks are fixedly connected to the upper outer side of the sedimentation tank, and an electric push rod is fixedly connected to each mounting block. A pressing rod is fixedly connected to the telescopic rod of each electric push rod. Both pressing rods are slidably connected to the sedimentation tank, and an extrusion screen is slidably connected between the lower parts of the two pressing rods. The extrusion screen is located inside the sedimentation tank.

[0010] Furthermore, it is particularly preferred that a reset mechanism is also included, which includes a fixed block, an elastic plate, and a locking block. Two fixed blocks are fixedly connected to the upper end of the sedimentation tank, and four elastic plates are fixedly connected to the upper end of the extrusion screen. Two elastic plates form a group, and a locking block is fixedly connected to each elastic plate.

[0011] Furthermore, it is particularly preferred that the device also includes a vibration mechanism, which includes an opening block and a connecting spring. The lower end of each pressing rod is fixedly connected to an opening block, and each opening block has a latch. Two connecting springs are fixedly connected between the two pressing rods and an extrusion mesh, and the two connecting springs are located inside the two pressing rods respectively.

[0012] Furthermore, it is particularly preferred that the settling tank also includes a scraping mechanism, which includes an electric ring, a rotating ring, a strong magnet, and a scraper. The electric ring is fixedly connected to the settling tank, the rotating ring is fixedly connected to the electric ring, the strong magnet is fixedly connected to the rotating ring, and the scraper is rotatably connected to the bottom of the settling tank. The scraper is made of steel and is attracted to the strong magnet.

[0013] Furthermore, it is particularly preferred that the scraper is used to separate the precipitate.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The downward movement of the telescopic rod of the electric push rod will drive the pressure rod and the extrusion net to move downward. The downward movement of the extrusion net will come into contact with the mixed liquid. The extrusion net continues to move downward in the mixed liquid. The extrusion net will push the floating precipitate in the mixed liquid downward. The extrusion net assists the precipitate to settle faster, thereby making the sedimentation effect better.

[0015] 2. The downward movement of the perforated block compresses the connecting spring, which in turn causes the squeezing screen to apply pressure to the sediment, thus fixing the sediment better at the bottom of the sedimentation tank. The rotation of the sedimentation tank and the squeezing screen causes the sediment to be at the top. Since the connecting spring applies pressure to the sediment through the squeezing screen, the squeezing screen squeezes out the water in the sediment, thereby improving the sedimentation effect.

[0016] 3. The electric ring drives the rotating ring and the strong magnet to rotate. The rotation of the strong magnet will drive the scraper to rotate through magnetic force. The rotating scraper scrapes the sediment after it has been squeezed by the squeezing screen, so that the sediment is separated from the sedimentation tank and the squeezing screen. The sediment separated from the sedimentation tank and the squeezing screen falls into the guide frame through the solenoid valve, so that the sediment can be discharged better.

[0028] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0029] Example 1; A sedimentation treatment device for electronic wastewater based on MBR membrane, such as Figures 1-7 As shown, the system includes a collection frame 1, MBR membrane plates 2, a fixing frame 3, a sedimentation tank 4, a solenoid valve 41, a solenoid valve 42, a reduction mechanism, a switching mechanism, and an auxiliary mechanism. Each collection frame 1 has a discharge hole. A fixing frame 3 is welded together on two collection frames 1. Three MBR membrane plates 2 are bolted to one of the collection frames 1. The sedimentation tank 4 is rotatably connected to the upper part of the fixing frame 3. Solenoid valve 41 is fixedly connected to the bottom of the sedimentation tank 4, and solenoid valve 42 is fixedly connected to the top of the sedimentation tank 4. The fixing frame 3 is equipped with a reduction mechanism and a switching mechanism for switching the discharge port. The sedimentation tank 4 is equipped with an auxiliary mechanism for assisting in the sedimentation of impurities.

[0030] The reduction mechanism includes a motor bracket 5, a drive motor 6, and a reduction gearbox 7. The motor bracket 5 is bolted to one side of the fixed frame 3, and the drive motor 6 is bolted to the motor bracket 5. The reduction gearbox 7 is fixedly connected to one side of the fixed frame 3. The reduction gearbox 7 is used for speed reduction and torque increase. The reduction gearbox 7 is provided with an input end and an output end. The input end of the reduction gearbox 7 is fixedly connected to the output shaft of the drive motor 6, and the output end of the reduction gearbox 7 is fixedly connected to the sedimentation tank 4.

[0031] The switching mechanism includes guide rods 81, partition plates 82, return springs 83, connecting plates 84, flow guides 85, and push rods 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. Two return springs 83 are connected between the partition plate 82 and the fixed frame 3. A connecting plate 84 is welded to the bottom of the partition plate 82. Two flow guides 85 are welded to the connecting plate 84. The flow guide surface of the flow guide 85 is inclined. Two push rods 86 are welded to the top of the sedimentation tank 4.

[0032] The separator 82 is used to separate the two flow guides 85.

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

[0034] Initially, the staff opened solenoid valve 42. Then, they added electronic wastewater to sedimentation tank 4, followed by the addition of chemicals. The water level in sedimentation tank 4 was below the squeezing screen 94. Finally, the staff started the drive motor 6 and closed solenoid valve 42. The drive motor 6 rotated back and forth slightly. The output shaft of the drive motor 6, after being reduced in speed and torque by the reduction gearbox 7, caused sedimentation tank 4, solenoid valves 41 and 42, push rod 86, mounting block 91, electric push rod 92, pressing rod 93, and squeezing screen 94 to swing slightly. This swinging motion of sedimentation tank 4 ensured thorough mixing of the electronic wastewater and chemicals. The mixture forms a liquid mixture. The electronic wastewater and chemicals, when mixed, cause sediment to form. After mixing, the operator turns off the drive motor 6 and waits for the mixture in the sedimentation tank 4 to settle. A small portion of the sediment falls to the bottom of the sedimentation tank 4, while most floats in the mixture. The operator then activates the electric push rod 92. The extension rod of the electric push rod 92 moves downward, causing the pressure rod 93 and the squeezing screen 94 to move downward as well. The squeezing screen 94 comes into contact with the mixture and continues to move downward within it. The squeezing screen 94 pushes the floating sediment downward, assisting in faster sedimentation and thus promoting faster settling. For better sedimentation, the squeezing screen 94 moves to the bottom of the sedimentation tank 4 and stops moving. The downward pressure rod 93 continues to move, which will restrict the squeezing screen 94 to the bottom of the sedimentation tank 4. Then, the operator closes the electric push rod 92 and starts the drive motor 6. The output shaft of the drive motor 6 will drive the sedimentation tank 4, solenoid valve 41, solenoid valve 42, push rod 86, mounting block 91, electric push rod 92, downward pressure rod 93 and squeezing screen 94 to rotate 180 degrees through the reduction gearbox 7. The operator closes the drive motor 6. The squeezing screen 94 restricts the sediment inside the sedimentation tank 4 to the end near solenoid valve 41. The bottom of the sedimentation tank 4 contains a relatively clean mixed liquid. The push rod 86 rotates 180 degrees and will interact with the partition plate 82. Contacting and pushing the separator plate 82 to move it causes the connecting plate 84 and the two guide frames 85 to move as well. The operator opens solenoid valve 42, allowing the mixed liquid at the bottom of the sedimentation tank 4 to flow into one of the guide frames 85. The mixed liquid then flows through the guide frame 85 into the collection frame 1 where the MBR membrane plate 2 is installed. The mixed liquid is filtered by the MBR membrane plate 2 and then flows from the outlet of the collection frame 1 to the next step. After the mixed liquid in the sedimentation tank 4 is emptied, the operator closes solenoid valve 42 and starts the electric push rod 92. The electric push rod 92 causes the pressure rod 93 and the extrusion screen 94 to reset a short distance. Then, the operator closes the electric push rod 92 and starts the drive motor 6.The output shaft of drive motor 6 drives the sedimentation tank 4, solenoid valve 41, solenoid valve 42, push rod 86, mounting block 91, electric push rod 92, pressing rod 93, and extrusion screen 94 to reverse and reset via reduction gearbox 7. Push rod 86, upon reversing and resetting, disengages from partition plate 82. Partition plate 82, connecting plate 84, and guide frame 85 reset under the action of reset spring 83. Then, the operator shuts off drive motor 6 and opens solenoid valve 41. Sediment in sedimentation tank 4 is discharged through solenoid valve 41, falling onto another guide frame 85 and flowing through it into collection frame 1 (where MBR membrane plate 2 is not installed). After the sediment is discharged, the operator activates electric push rod 92. The extension rod of electric push rod 92 resets the extrusion screen 94. After the extrusion screen 94 resets, the operator closes solenoid valve 41, activates solenoid valve 42, and closes electric push rod 92.

[0035] Example 2: Based on Example 1, such as Figures 6-7 As shown, it also includes a reset mechanism, which includes a fixed block 101, an elastic plate 102 and a locking block 103. Two fixed blocks 101 are welded to the upper end of the sedimentation tank 4, and four elastic plates 102 are welded to the extrusion mesh 94. Two elastic plates 102 form a group, and a locking block 103 is welded to each elastic plate 102.

[0036] It also includes a vibration mechanism, which includes an opening block 104 and a connecting spring 105. The lower end of each pressing rod 93 is welded with an opening block 104, and each opening block 104 has a slot. Two connecting springs 105 are fixedly connected between the two pressing rods 93 and an extrusion mesh 94. The two connecting springs 105 are located inside the two pressing rods 93 respectively.

[0037] The downward movement of the pressure rod 93 and the extrusion mesh 94 causes the elastic plate 102, the locking block 103, the perforation block 104, and the connecting spring 105 to move downwards. When the extrusion mesh 94 contacts the bottom of the sedimentation tank 4 and stops moving, the elastic plate 102 and the locking block 103 also stop moving. The continued downward movement of the pressure rod 93 causes the perforation block 104 to move downwards. The downward movement of the perforation block 104 compresses the connecting spring 105, which in turn causes the extrusion mesh 94 to apply pressure to the sediment, better fixing the sediment to the bottom of the sedimentation tank 4. At the same time, the perforation block 105... Moving downwards will compress the locking block 103, causing it to move. This movement of the locking block 103 will deform the elastic plate 102. As the perforated block 104 continues to move downwards, the locking block 103 disengages from the perforated block 104. The reset of the elastic plate 102 will cause the locking block 103 to reset, and the reset locking block 103 will engage with the slot of the perforated block 104. Then, the rotation of the sedimentation tank 4 will cause the fixed block 101, elastic plate 102, locking block 103, perforated block 104, and connecting spring 105 to rotate. The rotation of the sedimentation tank 4 and the extrusion screen 94 will cause the sediment to rise to the top, where it will be... The connecting spring 105 applies pressure to the sediment through the squeezing mesh 94, which squeezes out the water from the sediment, thus improving the sedimentation effect. After the sedimentation tank 4 rotates, the solenoid valve 42 begins to discharge the mixed liquid. After the mixed liquid is discharged, the rotation of the sedimentation tank 4 will cause the fixed block 101, elastic plate 102, locking block 103, opening block 104 and connecting spring 105 to reverse and reset. Then, the resetting of the lower pressure rod 93 and the squeezing mesh 94 will cause the elastic plate 102, locking block 103, opening block 104 and connecting spring 105 to return to their original positions. When the locking block 103 moves upward, it will contact the fixing block 101. When the locking block 103 continues to move upward, the fixing block 101 will push the locking block 103 to move. The movement of the locking block 103 will cause the elastic plate 102 to bend, and the movement of the locking block 103 will disengage from the opening block 104. The extrusion mesh 94, the elastic plate 102 and the locking block 103 will quickly reset under the action of the connecting spring 105. The rapid reset of the extrusion mesh 94 will generate vibration. The vibration of the extrusion mesh 94 will shake off the residual sediment on the extrusion mesh 94. The shaken-off sediment will flow out through the solenoid valve 41.

[0038] Example 3: Based on Example 2, such as Figures 8-10 As shown, it also includes a scraping mechanism, which includes an electric ring 111, a rotating ring 112, a strong magnet 113, and a scraper 115. The electric ring 111 is bolted to the sedimentation tank 4, and the rotating ring 112 is fixedly connected to the electric ring 111. The strong magnet 113 is bolted to the rotating ring 112. The scraper 115 is rotatably connected to the bottom of the sedimentation tank 4. The scraper 115 is made of steel and is attracted to the strong magnet 113.

[0039] The scraper 115 is used to separate precipitates.

[0040] When the sedimentation tank 4 swings, the operator activates the electric ring 111, which drives the rotating ring 112 to rotate. The rotating ring 112 then drives the strong magnet 113 to rotate, which in turn drives the scraper 115 to rotate via magnetic force. The scraper 115 agitates the electronic wastewater and reagents, ensuring a more thorough mixing. When the sedimentation tank 4 stops swinging, the operator closes the electric ring 111, and the rotating ring 112, strong magnet 113, and scraper 115 stop moving. When the squeezing screen 94 assists in sedimentation, it moves downwards and contacts the scraper 115. After the mixed liquid is discharged, the operator activates the electric push rod 92, which drives the lowering rod 93 and the squeezing screen 94 to return to their original positions a short distance. This causes the squeezing screen 94 to disengage from the scraper 115. Then, the operator 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 will drive the scraper 115 to rotate through magnetic force. As the squeezing screen 94 returns to its original position a short distance, the scraper 115 rotates and scrapes the sediment squeezed by the squeezing screen 94, causing the sediment to disengage from the sedimentation tank 4 and the squeezing screen 94. The operator then 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, the discharge solenoid valve 41 is opened, and the sediment that has disengaged from the sedimentation tank 4 and the squeezing screen 94 falls into the guide frame 85 through the solenoid valve 41, allowing the sediment to be discharged more effectively.
