Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically a sodium methoxide wastewater treatment device. Background Technology

[0002] Sodium methoxide wastewater treatment equipment is mainly used to treat highly alkaline industrial wastewater containing sodium methoxide. Its core process is to adjust the pH value of the wastewater to neutral or near neutral through a neutralization reaction to ensure the safety and effectiveness of subsequent treatment stages. The equipment usually includes pretreatment, neutralization reaction, precipitation separation and advanced treatment units. The neutralization reaction is the key step, which requires the addition of acidic substances such as hydrochloric acid or sulfuric acid to react with sodium methoxide to produce methanol and the corresponding sodium salt (such as sodium chloride or sodium sulfate), thereby reducing the alkalinity of the wastewater and eliminating the strong corrosiveness of sodium methoxide. After treatment, the wastewater can enter the biological chemical system or be further purified.

[0003] In existing technologies, after neutralizing sodium methoxide wastewater, the salts generated by the reaction are mostly filtered by filter screens. However, the filter screens are easily clogged by the salts generated by the reaction, requiring frequent shutdowns for disassembly and cleaning. This is cumbersome, affects continuous production, and reduces the efficiency of wastewater treatment. Furthermore, traditional devices lack automatic cleaning functions, and residual wastewater and crystals can easily corrode the filter screens, reducing their service life. Summary of the Invention

A first elastic element is provided on the outside of the slide rod. The two ends of the first elastic element are fixedly connected to the top of the limiting block and the bottom of the baffle, respectively. A pressing block capable of pressing the baffle is fixed on the outside of the rotating rod.

[0011] Preferably, one of the limiting blocks has a fixing component inside, which is used to fix the slide rod when the slide rod moves to the lowest point.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0027] In one embodiment, see Figure 1 and Figure 2 A sodium methoxide wastewater treatment device includes a treatment tank 1. An arc-shaped mesh cylinder 11 is installed inside the treatment tank 1, with its sidewalls fitting against the inner wall of the treatment tank 1. An inlet pipe 4 is installed above the arc-shaped mesh cylinder 11 on the sidewall of the treatment tank 1, and an outlet pipe 5 is installed below the arc-shaped mesh cylinder 11 on the sidewall of the treatment tank 1. A first turntable 7 and a second turntable 8 are fixed to the ends of the arc-shaped mesh cylinder 11, respectively. The diameters of the first turntable 7 and the second turntable 8 are the same as the diameter of the arc-shaped mesh cylinder 11. The ends of the first turntable 7 and the second turntable 8 furthest from the arc-shaped mesh cylinder 11 are connected to... The inner wall of the treatment tank 1 is fitted together, and a motor 6 is fixed on the outer wall of the treatment tank 1. A rotating rod 10 is installed at the output end of the motor 6. The rotating rod 10 passes through the side wall of the treatment tank 1 and is rotatably connected to the side wall of the treatment tank 1. The rotating rod 10 passes through the inside of the first turntable 7 and the second turntable 8. Multiple stirring rods 9 are fixed outside the rotating rod 10. The arc-shaped mesh cylinder 11 is connected to a rotating mechanism 2. A neutralization mechanism 3 is provided above the arc-shaped mesh cylinder 11. The rotating mechanism 2 is used to drive the arc-shaped mesh cylinder 11 to swing back and forth and flip over. The neutralization mechanism 3 is used to neutralize the sodium methoxide wastewater.

[0028] In this embodiment, when treating sodium methoxide wastewater, the device inputs the wastewater into the treatment tank 1 through the inlet pipe 4. Simultaneously, the neutralization mechanism 3 above the arc-shaped mesh cylinder 11 removes alkaline substances from the wastewater. The salts generated during the reaction precipitate at the bottom of the arc-shaped mesh cylinder 11, thus filtering the generated salts and achieving solid-liquid separation. This ensures efficient treatment of the sodium methoxide wastewater. The neutralized wastewater is discharged directly through the outlet pipe 5 below the arc-shaped mesh cylinder 11. Furthermore, during the treatment of sodium methoxide wastewater, the motor 6 can be activated, driving the rotating rod 10 to rotate. The rotating rod 10 drives the stirring rod 9 to rotate, stirring the sodium methoxide wastewater and increasing the contact area between the wastewater and the reaction solution, thus ensuring the neutralization effect. Simultaneously, the rotating rod 10 also drives the arc-shaped mesh cylinder 11 to oscillate back and forth via the rotating mechanism 2. This effectively prevents the accumulation of salts generated during the neutralization reaction at the bottom of the arc-shaped mesh cylinder 11, allowing the sodium methoxide wastewater to pass smoothly through it, ensuring its flow rate and treatment efficiency. After the sodium methoxide wastewater is treated, the rotating mechanism 2 rotates the arc-shaped mesh cylinder 11 180°, so that the opening at the top of the cylinder faces... Simultaneously, staff inject clean water into the treatment tank 1 through the water inlet pipe 4. Under the flushing action of the clean water, the salt impurities adsorbed at the bottom of the arc-shaped screen cylinder 11 automatically fall to the bottom of the treatment tank 1, thus cleaning the arc-shaped screen cylinder 11. This also prevents corrosion caused by residual sodium methoxide wastewater, extending the service life of the arc-shaped screen cylinder 11. Furthermore, it eliminates the need for manual removal of the arc-shaped screen cylinder 11 from the treatment tank 1, saving manpower. After cleaning, the rotating mechanism 2 resets the arc-shaped screen cylinder 11, allowing it to filter the sodium methoxide wastewater again. In other words, this sodium methoxide wastewater treatment device uses the arc-shaped screen cylinder 11... The synergistic effect of neutralization mechanism 3 significantly improves wastewater treatment efficiency and solid-liquid separation. Neutralization mechanism 3 allows sodium methoxide to fully react with acidic reagents, and the resulting salt precipitate is intercepted by arc-shaped mesh cylinder 11, achieving efficient filtration. The stirring rod 9 driven by motor 6 enhances the mixing of the reaction liquid and promotes the neutralization reaction, while the rotating mechanism 2 drives the arc-shaped mesh cylinder 11 to swing back and forth to prevent salt accumulation and ensure smooth wastewater flow. After treatment, the arc-shaped mesh cylinder 11 can be rotated 180° to automatically rinse residual salts with clean water, avoiding manual cleaning, reducing corrosion risk and extending equipment life. The overall design has a high degree of automation, balancing treatment efficiency and maintenance convenience, and is suitable for continuous industrial wastewater treatment.

[0029] Please see Figures 2-4The rotating mechanism 2 includes a first gear 23 disposed inside the processing box 1 and below the first turntable 7. The first gear 23 is connected to a rotating assembly, which is used to drive the first gear 23 to rotate. The first turntable 7 has a recess 21 on the side away from the arc-shaped mesh cylinder 11, wherein the diameter of the recess 21 is smaller than the diameter of the first turntable 7. A toothed ring 22 is fixed on the outer wall of the recess 21, and the toothed ring 22 meshes with the first gear 23. An arc-shaped cover plate 24 is fixed above the first turntable 7 and on the inner wall of the processing box 1, and the inner wall of the arc-shaped cover plate 24 is in contact with the inner wall of the first turntable 7.

[0030] When treating sodium methoxide wastewater, a rotating assembly drives the first gear 23 to reciprocate. The meshing of the first gear 23 with the gear ring 22 drives the first turntable 7 to reciprocate, which in turn drives the arc-shaped screen cylinder 11 to reciprocate. This prevents salts from accumulating at the bottom of the arc-shaped screen cylinder 11, ensuring smooth wastewater flow and guaranteeing efficient treatment of the sodium methoxide wastewater. After the sodium methoxide wastewater is treated, the rotating assembly drives the first gear 23 to move in one direction. The meshing of the first gear 23 with the gear ring 22 drives the first turntable 7 to rotate until the arc-shaped screen cylinder 11 rotates 180°, meaning the opening at the top of the arc-shaped screen cylinder 11 faces downwards. Then, workers can inject clean water into the treatment tank 1 through the water inlet pipe 4. Under the flushing action of the clean water, the salt impurities adsorbed at the bottom of the arc-shaped screen cylinder 11 automatically fall to the bottom of the treatment tank 1. This process cleans the arc-shaped screen cylinder 11 and prevents corrosion caused by residual sodium methoxide wastewater, thus extending its service life. It also eliminates the need for manual removal of the arc-shaped screen cylinder 11 from the treatment box 1, saving manpower. After cleaning, the rotating assembly drives the first gear 23 to rotate in the opposite direction. The meshing of the first gear 23 with the gear ring 22 drives the first turntable 7 to rotate in the opposite direction until the opening at the top of the arc-shaped screen cylinder 11 faces downwards again, allowing the arc-shaped screen cylinder 11 to filter the sodium methoxide wastewater again. The arc-shaped cover plate 24 seals the recess 21 on the side wall of the first turntable 7, preventing sodium methoxide wastewater from flowing directly from the recess 21 into the arc-shaped screen cylinder 11, ensuring effective treatment of the sodium methoxide wastewater.

[0031] Please see Figure 2 Multiple arc-shaped blocks 217 are fixed on the inner wall of the processing box 1 in a symmetrical arrangement, and the inner walls of the arc-shaped blocks 217 are all in contact with the outer wall of the first turntable 7.

[0032] While the first turntable 7 rotates, it drives the second turntable 8 to rotate through the arc-shaped mesh cylinder 11. At this time, multiple arc-shaped blocks 217 can limit the second turntable 8, thereby effectively improving the stability of the arc-shaped mesh cylinder 11 during rotation.

[0033] Please see Figure 3 and Figure 4 The rotating assembly includes a transmission rod 25 fixedly connected to the first gear 23. The transmission rod 25 passes through the side wall of the processing box 1 and is rotatably connected to the side wall of the processing box 1. A second gear 26 is fixed to the end of the transmission rod 25 away from the first gear 23. The second gear 26 meshes with a toothed plate 27. The toothed plate 27 is connected to a lifting component, which is used to drive the toothed plate 27 to move up and down.

[0034] When treating sodium methoxide wastewater, the lifting component drives the toothed plate 27 to move up and down. During the up and down movement of the toothed plate 27, it meshes with the second gear 26 to drive the transmission rod 25 to rotate back and forth. At the same time, the transmission rod 25 rotates back and forth, which in turn drives the first gear 23 to rotate back and forth. The meshing of the first gear 23 with the toothed ring 22 drives the first turntable 7 to swing back and forth. The first turntable 7 drives the arc-shaped mesh cylinder 11 to swing back and forth, thereby preventing salts from accumulating at the bottom of the arc-shaped mesh cylinder 11, ensuring smooth flow of wastewater, and guaranteeing the treatment efficiency of sodium methoxide wastewater.

[0035] Please see Figure 5 The lifting component includes a baffle 28 fixedly connected to the top of the toothed plate 27. A symmetrically distributed slide rod 210 is fixed at the bottom of the baffle 28. A symmetrically distributed limiting block 211 is fixed on the outer wall of the processing box 1. The slide rod 210 passes through the limiting block 211 and is slidably connected to the limiting block 211. A first elastic element 214 is provided on the outside of the slide rod 210. The two ends of the first elastic element 214 are fixedly connected to the top of the limiting block 211 and the bottom of the baffle 28, respectively. A pressing block 29 capable of pressing the baffle 28 is fixed on the outside of the rotating rod 10.

[0036] When treating sodium methoxide wastewater, motor 6 is started, which drives rotating rod 10 to rotate. Rotating rod 10 then drives stirring rod 9 to rotate, stirring the sodium methoxide wastewater and increasing the contact area between the wastewater and the reaction solution, thus ensuring the neutralization effect. During the rotation of rotating rod 10, extrusion block 29 also rotates, periodically extruding baffle 28. When extrusion block 29 extrudes baffle 28, baffle 28 causes toothed plate 27 to move downwards. When extrusion block 29 stops extruding baffle 28, baffle 28 automatically resets under the action of first elastic element 214, thereby driving... The toothed plate 27 moves upward, and the first elastic element 214 can be a spring. This cycle repeats, allowing the toothed plate 27 to move up and down continuously. This causes the second gear 26 to drive the first gear 23 to rotate back and forth via the transmission rod 25. The meshing of the first gear 23 with the toothed ring 22 drives the first turntable 7 to swing back and forth. The first turntable 7 then drives the arc-shaped mesh cylinder 11 to swing back and forth, thereby preventing salts from accumulating at the bottom of the arc-shaped mesh cylinder 11, ensuring smooth wastewater flow, and guaranteeing the treatment efficiency of sodium methoxide wastewater. Furthermore, the limiting block 211 can limit the movement of the baffle 28 via the slide rod 210, effectively improving the stability of the baffle 28 when it moves up and down.

[0037] Please see Figure 5 One of the limiting blocks 211 has a fixing component inside, which is used to fix the slide rod 210 when the slide rod 210 moves to the lowest point;

[0038] During the treatment of sodium methoxide wastewater, the rotating rod 10 also drives the extrusion block 29 to rotate. The extrusion block 29 periodically extrudes the baffle 28 during its rotation. When the extrusion block 29 extrudes the baffle 28, the baffle 28 drives the toothed plate 27 to move downwards. When the extrusion block 29 stops extruding the baffle 28, the baffle 28 automatically resets under the action of the first elastic element 214, thereby driving the toothed plate 27 to move upwards. This cycle repeats, allowing the toothed plate 27 to continuously move up and down. During this process, the arc-shaped screen cylinder 11 remains in a swinging state and cannot be flipped. When the sodium methoxide wastewater treatment is complete and the arc-shaped screen cylinder 11 needs cleaning, the baffle 28 is manually pressed downwards, causing the baffle 28 to drive the toothed plate 27 to continue moving downwards. The meshing of gear 27 with the second gear 26 drives the transmission rod 25 to rotate, and the transmission rod 25 drives the first gear 23 to rotate. The meshing of the first gear 23 with the gear ring 22 drives the first turntable 7 to rotate until the arc-shaped mesh cylinder 11 rotates 180°, that is, the opening at the top of the arc-shaped mesh cylinder 11 faces downward. Then, the staff can inject clean water into the treatment tank 1 through the water inlet pipe 4. Under the flushing of clean water, the salt impurities adsorbed at the bottom of the arc-shaped mesh cylinder 11 automatically fall to the bottom of the treatment tank 1, thereby cleaning the arc-shaped mesh cylinder 11. When the arc-shaped mesh cylinder 11 rotates 180°, the fixing component inside the limit block 211 will automatically fix the slide rod 210. The slide rod 210 fixes the toothed plate 27 through the baffle 28, thereby ensuring the stability of the arc-shaped mesh cylinder 11 during the rinsing process.

[0039] Please see Figure 5 The fixing component includes a pin 213 that penetrates the side wall of the limiting block 211. The pin 213 is connected to the outer wall of the limiting block 211 through a second elastic member 215. The sliding rod 210 has a pin groove 212 on its side wall that is adapted to the pin 213.

[0040] When the sodium methoxide wastewater is treated, the baffle 28 is pressed down manually. The baffle 28 drives the toothed plate 27 to move downward continuously. The meshing of the toothed plate 27 with the second gear 26 drives the transmission rod 25 to rotate. The transmission rod 25 drives the first gear 23 to rotate. The meshing of the first gear 23 with the toothed ring 22 drives the first turntable 7 to rotate until the arc-shaped mesh cylinder 11 rotates 180°. At this time, the end of the pin 213 automatically enters the pin groove 212 on the side wall of the slide rod 210 under the action of the second elastic element 215. The pin 213 then fixes the slide rod 210 through the pin groove 212, effectively ensuring the stability of the baffle 28 and thus improving the stability of the arc-shaped mesh cylinder 11 during the rinsing process. The second elastic element 215 can be a spring.

[0041] Please see Figure 2 and Figure 6The neutralization mechanism 3 includes a branch pipe 31 that penetrates the side wall of the treatment tank 1. The bottom of the branch pipe 31 is provided with a liquid outlet 32. The outer wall of the treatment tank 1 is provided with a mounting frame. A liquid injection cylinder 33 penetrates the inside of the mounting frame. The liquid injection cylinder 33 is detachably connected to the mounting frame. The liquid outlet end of the liquid injection cylinder 33 is inserted into the inside of the branch pipe 31. The liquid injection cylinder 33 is provided with a liquid injection assembly, which is used to inject the acidic solution inside the liquid injection cylinder 33 into the inside of the branch pipe 31.

[0042] When treating sodium methoxide wastewater, the wastewater is introduced into the treatment tank 1 through the inlet pipe 4. At the same time, the acidic solution inside the injection cylinder 33 is injected into the branch pipe 31 through the injection assembly. After entering the branch pipe 31, the acidic solution is discharged from the outlet hole 32 at the bottom of the branch pipe 31, and finally reacts chemically with the sodium methoxide wastewater to achieve the purpose of treating the sodium methoxide wastewater. The detachable connection between the injection cylinder 33 and the mounting frame facilitates the installation of the injection cylinder 33. When the acidic solution inside the injection cylinder 33 is used up, the injection cylinder 33 can be directly removed from the limiting frame 34, and then the external acidic solution can be extracted again.

[0043] Please see Figure 6 and Figure 7 The injection assembly includes a piston 39 disposed inside the injection cylinder 33. The piston 39 is slidably connected to the inner wall of the injection cylinder 33. A threaded sleeve 38 is fixed to the end of the piston 39. A threaded rod 37 is threadedly connected to the end of the threaded sleeve 38 away from the piston 39. The threaded rod 37 passes through the end of the injection cylinder 33 and is rotatably connected to the end of the injection cylinder 33. A third gear 35 is fixed to the end of the threaded rod 37. An incomplete gear 36 that can mesh with the third gear 35 is fixed to the end of the rotating rod 10.

[0044] When treating sodium methoxide wastewater, motor 6 is started, which drives rotating rod 10 to rotate. Rotating rod 10 drives stirring rod 9 to rotate, thereby increasing the contact area between sodium methoxide wastewater and reaction liquid, and thus ensuring the neutralization effect of sodium methoxide wastewater. While rotating rod 10 is rotating, it also drives incomplete gear 36 to rotate. When incomplete gear 36 rotates to a certain extent, it meshes with third gear 35, thereby driving threaded rod 37 to rotate at a certain angle. While rotating, threaded rod 37 drives piston 39 to move inside injection cylinder 33 through threaded connection with threaded sleeve 38. Piston 39 squeezes the acidic solution inside injection cylinder 33, so that the acidic solution can intermittently enter the branch pipe 31. Combined with the continuous mixing of stirring rod 9, this ensures that the acid-base reaction is uniform and efficient, reduces the waste of acidic reagents, and improves the stability and economy of the neutralization process.

[0045] Please see Figure 7The threaded sleeve 38 is externally fixed with a slider 311, and the inner wall of the injection cylinder 33 is provided with a groove 310 that is adapted to the slider 311. The end of the slider 311 is located inside the groove 310 and is slidably connected to the groove 310.

[0046] As the threaded sleeve 38 moves, it drives the slider 311 to move inside the groove 310. The groove 310, through the slider 311, acts as a limit for the threaded sleeve 38, preventing the threaded rod 37 from rotating and causing the threaded sleeve 38 to rotate, thus ensuring the stability of the threaded sleeve 38 during movement.

[0047] Working Principle: When treating sodium methoxide wastewater, the device inputs the wastewater into the treatment tank 1 through the inlet pipe 4. The motor 6 is started, driving the rotating rod 10 to rotate, which in turn drives the stirring rod 9 to rotate, thus agitating the sodium methoxide wastewater. Simultaneously, the rotating rod 10 also drives the incomplete gear 36 to rotate. When the incomplete gear 36 rotates to a certain extent, it meshes with the third gear 35, causing the threaded rod 37 to rotate at a certain angle. Simultaneously, the threaded rod 37, through its threaded connection with the threaded sleeve 38, drives the piston 39 to move inside the injection cylinder 33. The piston 39 compresses the acidic solution inside the injection cylinder 33, allowing the acidic solution to intermittently enter. The acidic solution enters the branch pipe 31 and is discharged from the outlet 32 ​​at the bottom of the branch pipe 31, ultimately reacting chemically with the sodium methoxide wastewater. Combined with the continuous mixing by the stirring rod 9, this ensures a uniform and efficient acid-base reaction, reduces waste of acidic reagents, and improves the stability and economy of the neutralization process. Furthermore, the rotation of the rotating rod 10 also drives the squeezing block 29 to rotate. During this rotation, the squeezing block 29 periodically squeezes the baffle 28. When the squeezing block 29 squeezes the baffle 28, the baffle 28 causes the toothed plate 27 to move downwards. When the squeezing block 29 stops squeezing the baffle 28, the baffle 28 automatically resets, causing the toothed plate 27 to move upwards. This cycle repeats continuously, ensuring that the toothed plate 27... The toothed plate 27 moves up and down intermittently. During this movement, it meshes with the second gear 26, causing the transmission rod 25 to rotate reciprocally. Simultaneously, the transmission rod 25 rotates, causing the first gear 23 to rotate reciprocally. The meshing of the first gear 23 with the toothed ring 22 causes the first turntable 7 to swing reciprocally. The first turntable 7 then causes the arc-shaped mesh cylinder 11 to swing reciprocally, preventing salt accumulation at the bottom of the arc-shaped mesh cylinder 11 and ensuring smooth wastewater flow. This guarantees the treatment efficiency of sodium methoxide wastewater. When the sodium methoxide wastewater treatment is complete, manually pressing down on the baffle 28 causes the toothed plate 27 to continue moving downwards. The meshing of the toothed plate 27 with the second gear 26 rotates the transmission rod 25, which in turn rotates the first gear 23. The meshing of the first gear 23 and the gear ring 22 drives the first turntable 7 to rotate until the arc-shaped mesh cylinder 11 flips 180°, that is, the opening at the top of the arc-shaped mesh cylinder 11 faces downward. Then, the staff can inject clean water into the treatment tank 1 through the water inlet pipe 4. Under the flushing of the clean water, the salt impurities adsorbed at the bottom of the arc-shaped mesh cylinder 11 automatically fall to the bottom of the treatment tank 1, thereby cleaning the arc-shaped mesh cylinder 11. When the arc-shaped mesh cylinder 11 flips 180°, the end of the pin 213 automatically enters the pin groove 212 on the side wall of the slide bar 210. The pin 213 then fixes the slide bar 210 through the pin groove 212, effectively ensuring the stability of the baffle 28, thereby improving the stability of the arc-shaped mesh cylinder 11 during the rinsing process.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
