Technical Field

[0001] This invention relates to the field of chemical wastewater treatment technology, and in particular to a wastewater treatment device for manufacturing chemical products. Background Technology

[0002] Wastewater from the manufacture of chemical products is commonly referred to as chemical wastewater. It contains a wide variety of pollutants, including organic matter and heavy metal ions. These pollutants may originate from incomplete reactions of raw materials, impurities in the raw materials, and large amounts of solvents used in production. A series of effective treatment methods are needed to ensure that the wastewater meets discharge standards or is recycled.

[0018] 1. This invention, through the combination of a limiting mechanism and a scraping mechanism, can fully agitate the wastewater during the removal of heavy metal ions, and collect and discharge the precipitated heavy metal precipitates, thus preventing the precipitates from affecting subsequent filtration. At the same time, the combination of the limiting mechanism and the agitation mechanism can cause organic matter to precipitate by rotating forward, and can also filter the wastewater by rotating backward, thereby improving the utilization rate and flexibility of the equipment. Furthermore, the agitation mechanism and the ultrafiltration membrane work together to remove organic matter from the wastewater more thoroughly, further improving the efficiency of wastewater treatment.

[0019] 2. This invention utilizes a limiting mechanism that coordinates the forward and reverse rotation of the motor and the first rotating roller. When the first rotating roller rotates forward, it can simultaneously remove heavy metal ions from the wastewater to be treated using the first sealing plate and filter plate, while also collecting heavy metal ion precipitates. Furthermore, the second sealing plate, along with two rectangular troughs and a second filter screen, can discharge the wastewater that has been treated for organic matter and heavy metal ions. When the first rotating roller rotates in reverse, the wastewater that has had heavy metal ions removed can flow to the next stage for the removal of organic matter, while also discharging the heavy metal ion precipitates. This not only improves the overall efficiency of wastewater treatment for chemical products but also increases the flexibility of wastewater treatment, making the separation and discharge of wastewater and precipitates more efficient.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1, as Figure 1 and Figure 2 As shown, a wastewater treatment device for manufacturing chemical products includes a treatment tank 1. A rotating mechanism 2 is fixedly connected to the upper end of the treatment tank 1. A limiting mechanism 3 is provided on the inner surface of the treatment tank 1. A scraping mechanism 4 is provided in the middle of the rotating mechanism 2 on the inner surface of the treatment tank 1. A stirring mechanism 5 is provided in the lower part of the rotating mechanism 2 on the inner surface of the treatment tank 1. An ultrafiltration membrane 6 is fixedly connected to the lower part of the inner surface of the treatment tank 1.

[0033] After the chemical products are manufactured, the wastewater discharged generally contains heavy metal ions, organic matter and some solid precipitates. After the wastewater passes through basic filtration and sedimentation, the wastewater generated from the manufacture of chemical products is transported to the treatment tank 1 for the removal of heavy metal ions and soluble organic matter. During the transportation process, a heavy metal ion precipitant is added to the inner surface of the treatment tank 1.

[0034] Inside the treatment tank 1, the rotating mechanism 2 drives the scraping mechanism 4 to rotate. The scraping mechanism 4, in conjunction with the limiting mechanism 3, first stirs the wastewater. Then, the scraping mechanism 4 can collect the precipitate formed by the precipitation of heavy metal ions. Subsequently, in conjunction with the rotating mechanism 2, the precipitate collected by the scraping mechanism 4 is discharged from the inside of the treatment tank 1. At the same time, the wastewater that has had its heavy metal ions removed falls to the upper end of the stirring mechanism 5 after passing through part of the structure of the scraping mechanism 4. Then, in conjunction with the stirring mechanism 5 and the treatment tank 1, an organic coagulant is released above the stirring mechanism 5.

[0035] Next, the rotating mechanism 2, in conjunction with the stirring mechanism 5, continuously stirs the wastewater when the organic coagulant is first added, helping it to mix thoroughly with the wastewater. After thorough mixing, the rotating mechanism 2 stops operating, allowing the wastewater and organic coagulant to react fully. Subsequently, the rotating mechanism 2, stirring mechanism 5, and limiting mechanism 3 work together to filter and discharge the wastewater with removed organic matter onto the upper part of the ultrafiltration membrane 6. At the same time, the stirring mechanism 5 scrapes off and collects the precipitated organic matter. After treatment, the wastewater, having had heavy metal ions and organic matter removed, slowly passes through the ultrafiltration membrane 6 and enters the bottom wall of the treatment tank 1. It can then be transported out for further testing and sterilization. Once the testing meets the standards, the wastewater can be discharged.

[0036] The ultrafiltration membrane 6 mentioned above is a conventional design in the prior art. Its main purpose, together with the stirring mechanism 5, is to thoroughly remove organic matter from wastewater.

[0037] See Figure 1 and Figure 2 The upper side of the treatment tank 1 has an inlet 11, the lower middle part of the treatment tank 1 has an outlet 16, the upper part of the inner surface of the treatment tank 1 has a through hole 14, the outer surface of the treatment tank 1 is fixedly connected to a collection box 13 outside the through hole 14, the inner surface of the treatment tank 1 is fixedly connected to a limit block 15 above the through hole 14, and the lower part of the outer surface of the treatment tank 1 is symmetrically fixedly connected to a coagulant box 17.

[0038] After preliminary filtration, the wastewater is conveyed through the inlet 11 to the inner surface of the treatment tank 1 via a conveying device in the prior art. During the conveying process, a fixed amount of wastewater is conveyed each time. As the wastewater is conveyed through the inlet 11 to the inner surface of the treatment tank 1, the heavy metal ion precipitant is also fed into the upper part of the inner surface of the treatment tank 1 according to the amount conveyed. The wastewater is mixed by the rotating mechanism 2 in conjunction with the scraping mechanism 4 and the limiting mechanism 3. After the heavy metal ion precipitation is completed, the heavy metal precipitate collected in the scraping mechanism 4 is released into the inner surface of the collection box 13 by the scraping mechanism 4 in conjunction with the through hole 14 and the limiting block 15. When the wastewater falls into the upper part of the stirring mechanism 5 to remove organic matter, the two coagulant boxes 17 on both sides release a fixed amount of organic matter coagulation precipitant into the upper part of the stirring mechanism 5 to assist the stirring mechanism 5 in coagulating and settling the organic matter in the wastewater. Then, the coagulated and settled wastewater is filtered again through the ultrafiltration membrane 6 and released through the outlet 16. The treated wastewater is then subjected to further testing and discharge.

[0039] During operation in this embodiment, the limiting mechanism 3, in conjunction with the scraping mechanism 4, can fully stir the wastewater during the removal of heavy metal ions, and collect and discharge the precipitated heavy metal precipitates to prevent them from affecting subsequent filtration. At the same time, the limiting mechanism 3, in conjunction with the stirring mechanism 5, can cause organic matter to precipitate by rotating forward, and can also filter the wastewater by rotating backward, thus improving the utilization rate and flexibility of the equipment. Furthermore, the stirring mechanism 5 and the ultrafiltration membrane 6 work together to remove organic matter from the wastewater more thoroughly, further improving the efficiency of wastewater treatment.

[0040] Example 2 is based on Example 1. In order to achieve the effect of removing heavy metal ions from the wastewater to be treated, collecting heavy metal ion precipitates at the same time, and discharging the wastewater that has been treated with organic matter and heavy metal ions.

[0041] See Figure 2 The rotating mechanism 2 includes a motor 21 fixedly connected to the middle of the upper end of the processing tank 1. The output end of the motor 21 is fixedly connected to a rotating roller 22, which passes through the top of the processing tank 1 and extends to the inner surface of the processing tank 1.

[0042] When preparing to treat the wastewater generated from manufacturing chemical products, the motor 21 is activated so that its output end drives the rotating roller 22 to rotate forward or backward simultaneously, thereby cooperating with the scraping mechanism 4 and the stirring mechanism 5 to achieve different functions.

[0043] See Figure 6The scraping mechanism 4 includes a filter plate 43 rotatably connected to the middle of the outer surface of the rotating roller 22, a ring 41 slidably connected to the upper middle part of the outer surface of the rotating roller 22, a collection box 42 fixedly connected to one side of the outer surface of the ring 41, the bottom end of the collection box 42 being in close contact with the upper end of the filter plate 43, and a sealing plate 44 slidably connected to the lower middle part of the outer surface of the rotating roller 22.

[0044] Specifically, when the wastewater to be treated and the heavy metal ion precipitant enter the upper part of the inner surface of the treatment tank 1 through the feed inlet 11, the motor 21 is activated, causing its output end to rotate forward, thereby driving the rotating roller 22 to rotate forward. When the rotating roller 22 rotates forward, the annular ring 41 is driven down to the upper end of the filter plate 43 by the collection box 42, and at the same time, the sealing plate 44 slides up to be in close contact with the lower end of the filter plate 43. Then the rotating roller 22 continues to rotate, causing the annular ring 41 to drive the collection box 42 to rotate, continuously stirring the wastewater to ensure that the heavy metal ion precipitant and the wastewater react and mix fully. At the same time, during the stirring process, the heavy metal precipitates that are precipitated by the reaction are collected inside the collection box 42. Meanwhile, due to the cooperation between the sealing plate 44 and the filter plate 43, the wastewater will not flow to the upper part of the stirring mechanism 5 through the filter plate 43 and the sealing plate 44 before the treatment is completed.

[0045] The filter plate 43 mentioned above is a conventional design in the prior art. During its normal operation, water can pass through but solid particles cannot. At the same time, due to the setting of the gaps, solid particles can only stay on the surface and will not get stuck in the pores.

[0046] See Figure 7 A baffle 421 is slidably connected to the side of the collection box 2 42 near the inner surface of the treatment tank 1. An L-shaped rod 422 is fixedly connected to the upper end of the baffle 421. A sliding rod 423 is fixedly connected to the upper part of the vertical part of the L-shaped rod 422 near the inner surface of the treatment tank 1. A sliding rod 425 is fixedly connected to the lower part of the collection box 2 42 near the inner surface of the treatment tank 1. A push plate 424 is fixedly connected to one side of the collection box 2 42. The outer surface of the sliding rod 425 is slidably connected to the inner surface of the limiting groove 2 32. A sliding rod 441 is fixedly connected to the outer surface of the sealing plate 1 44. The outer surface of the sliding rod 441 is slidably connected to the inner surface of the limiting groove 4 34.

[0047] Furthermore, when the rotating roller 22 drives the ring 41 and the sealing plate 44 to rotate forward, the sealing plate 44, in conjunction with the filter plate 43, seals the filter plate 43 during its rotation, allowing the wastewater to fully react and mix with the heavy metal ion precipitant. During the rotation of the ring 41, the collection box 42 rotates. During the rotation of the collection box 42, the heavy metal precipitate deposited on the upper end of the filter plate 43 is allowed to enter the collection box 42 through the push plate 424. At the same time, the baffle 421, in conjunction with the collection box 42, seals the heavy metal precipitate inside the collection box 42.

[0048] Furthermore, when the output end of motor 21 drives the ring 41 and sealing plate 44 to reverse, the sealing plate 44 slides downward a distance through the cooperation of slide bar 3 441. At the same time, during the reverse rotation of ring 41, the collection box 2 42 and ring 41 slide upward a distance through the cooperation of slide bar 2 425. At this time, the filter plate 43 and sealing plate 44 are no longer in close contact, and the wastewater after removing heavy metal ions can slowly flow to the upper end of the stirring mechanism 5.

[0049] See Figure 10 Furthermore, during the reversal of the rotating roller 22 driving the collection box 42 and the ring 41, when the sliding rod 423 is driven to rotate until it is in close contact with the upper arc-shaped surface of the limiting block 15, as the sliding rod 423 moves, the arc-shaped setting of the limiting block 15 causes the sliding rod 423 to gradually move upward, which in turn drives the L-shaped rod 422 and the baffle 421 to move upward simultaneously. At this time, the collection box 42 is no longer in a sealed state, and the heavy metal deposits inside the collection box 42 are released along with the collection box 42. 2. Rotate and move to the side close to the baffle 421. As the baffle 421 moves upward, the heavy metal precipitate flows along the inner surface of the through hole 14 to the inner surface of the collection box 13 and is collected. Then, as the slide bar 423 descends along the arc surface of the limiting block 15, it gradually drives the baffle 421 to seal the collection box 2 42. Then, the rotating roller 22 drives the ring 41 and the collection box 2 42 to continuously reverse, so that the heavy metal precipitate inside the collection box 2 42 enters the inner surface of the collection box 13 through the through hole 14.

[0050] See Figure 8 , Figure 9 and Figure 10 The stirring mechanism 5 includes a sealing plate 51 that is slidably connected to the lower part of the outer surface of the rotating roller 22. A gear 57 is fixedly connected to the middle part of the upper end of the sealing plate 51. A fixing rod 53 is fixedly connected to one side of the inner surface of the processing tank 1. A telescopic rod 54 is fixedly connected to the end of the fixing rod 53 away from the inner surface of the processing tank 1. A horizontal plate 55 is fixedly connected to the lower end of the telescopic rod 54. Several rotating rollers 56 are rotatably connected to the lower end of the horizontal plate 55. A collection box 58 is fixedly connected to one side of the horizontal plate 55.

[0051] See Figure 10 When the first roller 22 rotates forward, the second sealing plates 51 and 52 are located in the lower-middle part of the inner surface of the treatment tank 1. During the reverse rotation of the first roller 22, the wastewater after the removal of heavy metal ions falls through the filter plate 43 and the first sealing plate 44 and falls above the second sealing plate 51. At this time, the second sealing plate 51 is located in the lower-middle part of the inner surface of the treatment tank 1. At this time, the telescopic rod 54 is stretched, the second gear 57 descends with the second sealing plate 51, and at the same time, the 59 and the horizontal plate 55, the third collection box 58 and several second rollers 56 move downward by the same distance.

[0052] At this time, the two coagulant boxes 17 cooperate to release a certain amount of organic coagulant and precipitant onto the upper end of the sealing plate 2 51 on the inner surface of the treatment tank 1. The sealing plate 2 51 cooperates with the inner surface of the treatment tank 1 to seal the sewage to be decomposed organic matter at the upper end of the sealing plate 2 51 on the inner surface of the treatment tank 1.

[0053] At this time, the rotating roller 22 reverses, and the sealing plate 51 is driven to reverse by the rotating roller 22, which in turn drives the gear 57 to rotate. In conjunction with 59 and the horizontal plate 55, several rotating rollers 56 operate simultaneously. During the reversal of the sealing plate 51, the several rotating rollers 56 continuously mix and stir the sewage and organic coagulation precipitant at the upper end of the sealing plate 51, ensuring thorough mixing and helping to disperse the organic coagulation precipitant. After rotating for a period of time, the motor 21 is stopped, and the sealing plate 51 stops rotating. At this time, the collection box 42 is also no longer driven to rotate. During the period when the motor 21 is stopped, the sewage and organic coagulation precipitant are given sufficient reaction time, allowing the soluble organic matter in the sewage to be converted into precipitate and precipitate.

[0054] See Figure 8 A gear 561 is fixedly connected to the lower part of the outer surface of several rotating rollers 22. The gear 561 on the side closer to the rotating roller 22 meshes with the gear 57. The gears 561 mesh with each other in pairs. A brush 562 is fixedly connected to the lower end of each gear 561. The lower end of each brush 562 is in close contact with the upper end of the sealing plate 21.

[0055] When the sealing plate 251 is driven to reverse by the rotating roller 22, the sealing plate 251 drives the gear 257 to rotate in the same direction. Then, through the cooperation with the gear 561 on the side close to the rotating roller 22 and the cooperation between each pair of gears 561, while the sealing plate 251 and the gear 257 are reversed, the gears 561 are driven to rotate at the same time. This enables the brushes 562 and the rotating roller 256 to rotate at the same time. During the rotation of the brushes 562, the sewage and organic coagulation precipitant at the upper end of the sealing plate 251 can be mixed.

[0056] After mixing for a period of time, stop the operation of motor 21 to allow the organic coagulant and precipitant to react fully with the wastewater.

[0057] See Figure 9 A sliding rod 511 is fixedly connected to the outer surface of the sealing plate 2 51. The outer surface of the sliding rod 511 is slidably connected to the inner surface of the limiting groove 6 36. A scraper 581 is fixedly connected to the side of the collection box 3 58 away from the horizontal plate 55. The lower end of the scraper 581 is in close contact with the upper end of the sealing plate 2 51.

[0058] After a period of time, the organic coagulant and precipitant react fully with the sewage. The soluble organic matter in the sewage is converted into precipitate and settles at the bottom of the wastewater. Then, the motor 21 is activated, causing the output end of the motor 21 to rotate forward. This causes the sealing plate 21 to rise a certain distance. As the sealing plate 21 moves upward, it drives several brushes 562, as well as the collection box 3 58, the horizontal plate 55, and the gear 2 57 to move in the same direction. After rising a certain distance, the operation of the motor 21 is immediately stopped. During the upward movement of the sealing plate 2 51, the collection box 3 58 and the horizontal plate 55 do not cause the sewage after the reaction to become turbid. Even if some precipitate is moved up, it will quickly settle at the top of the sealing plate 2 51.

[0059] Furthermore, after the sealing plate 2 51 rises a certain distance and stops, the wastewater that has had soluble organic matter removed from the upper part of the sealing plate 2 51 slowly flows to the upper part of the ultrafiltration membrane 6. After being filtered again by the ultrafiltration membrane 6, the organic matter in the wastewater is removed even more thoroughly. Then, the treated wastewater is tested and discharged through the discharge port 16.

[0060] See Figure 3 The limiting mechanism 3 includes a limiting groove 31 located in the upper middle part of the inner surface of the processing tank 1, a limiting groove 32 located below the limiting groove 31 on the inner surface of the processing tank 1, a limiting groove 34 located in the middle of the inner surface of the processing tank 1, a limiting groove 33 located below the limiting groove 34 on the inner surface of the processing tank 1, a limiting groove 36 located in the lower middle part of the inner surface of the processing tank 1, a limiting groove 35 located below the limiting groove 36 on the inner surface of the processing tank 1, a rectangular groove 37 symmetrically located in the middle of the inner surface of the processing tank 1, and a rectangular groove 38 symmetrically located in the lower middle part of the inner surface of the processing tank 1.

[0061] Specifically, when wastewater generated from the manufacture of chemical products is transported to the inner surface of treatment tank 1, the limiting grooves 31, 32, 33, and 34, in conjunction with the sliding rod 441, can both stir and mix the heavy metal ions in the wastewater and collect the heavy metal precipitates. At the same time, the wastewater after the removal of heavy metal ions can be released to the upper end of the sealing plate 51, while the collected heavy metal precipitates are released to avoid affecting the next treatment of heavy metal ions in the wastewater.

[0062] Similarly, limiting groove 5 35 and limiting groove 6 36 cooperate with slide rod 4 511 to treat organic matter in sewage, and cooperate with the coagulant released by the two coagulant boxes 17 to precipitate the organic matter in sewage.

[0063] See Figure 3The bottom wall of the inner surface of the first limiting groove 31 has an inclined groove 312 that extends through to the top wall of the inner surface of the second limiting groove 32. A stop block 321 is rotatably connected to the lower side of the inner surface of the inclined groove 312, and an inclined block 311 is rotatably connected to the upper side of the inner surface of the inclined groove 312 away from the stop block 321. The bottom wall of the inner surface of the fourth limiting groove 34 has an inclined groove 342 that extends through to the top wall of the inner surface of the third limiting groove 33. A stop block 331 is rotatably connected to the lower side of the inner surface of the inclined groove 342, and an inclined block is rotatably connected to the upper side of the inner surface of the inclined groove 342 away from the stop block 331. 341, the upper and lower parts of the inclined block 341 are fixedly connected to the treatment tank 1 by an elastic roller 343. The bottom wall of the inner surface of the limiting groove 36 has an inclined groove 362 that extends through to the top wall of the inner surface of the limiting groove 35. The lower part of the inner surface of the inclined groove 362 is rotatably connected to a stop block 351. The upper part of the inner surface of the inclined groove 362 away from the stop block 351 is rotatably connected to the inclined block 361. The two rectangular grooves 37 are fixedly connected to a filter screen 371 on the side close to each other. The two rectangular grooves 38 are fixedly connected to a filter screen 381 on the side close to each other.

[0064] When the output of motor 21 rotates forward, driving roller 22 to rotate forward, slide bar 425 rotates along the inner surface of limiting groove 32, and slide bar 441 rotates along the inner surface of limiting groove 34. At this time, sealing plate 44 is in close contact with the top and bottom walls of the inner surface of limiting groove 34.

[0065] See Figure 5 When the rotating roller 22 rotates forward, the sliding rod 511 rotates along the inner surface of the limiting groove 36. At the same time, the sealing plate 51 is in close contact with the top and bottom walls of the inner surface of the limiting groove 36. Part of the rectangular groove 38 is located at the upper end of the sealing plate 51, and the other part is located at the lower end of the sealing plate 51. Therefore, when the rotating roller 22 rotates forward and drives the sealing plate 51 to rise to be in close contact with the inner surface of the limiting groove 36, the rotation stops. At this time, the wastewater that removes organic matter at the upper end of the sealing plate 51 flows to the upper end of the ultrafiltration membrane 6 through the two rectangular grooves 38 on both sides and the filter screen 381.

[0066] Furthermore, after the sewage at the upper end of the sealing plate 2 51 flows into the upper end of the ultrafiltration membrane 6, the rotating roller 1 22 continues to rotate forward. At this time, the sealing plate 2 51 and the gear 2 57 are driven to rotate forward by the rotating roller 1 22. At this time, the organic matter settled at the upper end of the sealing plate 2 51 is pushed into the collection box 3 58 by the scraper 581. After all the treatment is completed, it is cleaned and removed.

[0067] See Figure 4When the rotating roller 22 rotates forward, it drives the sealing plate 44 to rotate, which in turn causes the sliding rod 441 to rotate along the inner surface of the limiting groove 34. When the sliding rod 441 rotates to contact the upper end of the inclined block 341, the sliding rod 441 continues to rotate, pressing the inclined block 341 downward and stretching the elastic roller 343. When the sliding rod 441 rotates away from the inclined block 341 and continues to rotate on the inner surface of the limiting groove 34, the elastic roller 343 drives the inclined block 341 to reset.

[0068] Furthermore, when the rotating roller 22 is driven to reverse, thereby causing the sealing plate 44 and the sliding rod 441 to reverse along the inner surface of the limiting groove 34, the sliding rod 441 rotates to the lower end of the inclined block 341. Through the setting of the inclined block 341, the sliding rod 441 moves downward along the inclined groove 342 and slides through the inner surface of the inclined groove 342 to the inner surface of the limiting groove 33. As the sealing plate 44 and the sliding rod 441 rise and fall simultaneously, the rotating roller 22 drives the sealing plate 44 to continue to reverse, causing the filter plate 43 to separate from the sealing plate 44.

[0069] Similarly, during the reverse rotation of the rotating roller 22 driving the sealing plate 44, the sliding rod 441 rotates in reverse along the inner surface of the limiting groove 33. When it rotates to the lower end of the stop block 331, the sliding rod 441 continues to rotate in reverse, pushing the stop block 331 upward. Then the sliding rod 441 continues to rotate in reverse. When the rotating roller 22 is driven to rotate forward, the sliding rod 441 rotates along the inner surface of the limiting groove 33 to the upper end of the stop block 331. Through the setting of the stop block 331, the sealing plate 44 and the sliding rod 441 rotate forward along the upper end of the stop block 331 into the inner surface of the inclined groove 342 and then into the inner surface of the limiting groove 34 for forward rotation.

[0070] In this way, the motor 21 drives the rotating roller 22, the sealing plate 44, and the slide bar 441 to achieve the effect of the sealing plate 44 being tightly attached to the filter plate 43 when rotating forward and separating from the filter plate 43 when rotating backward.

[0071] See Figure 5 When the rotating roller 22 drives the sealing plate 44 and the slide bar 441 to reverse, the sealing plate 44 is in close contact with the inner surface of the limiting groove 33. At this time, the upper part of the two rectangular grooves 37 is higher than the upper end of the sealing plate 44, and the lower part of the rectangular grooves 37 is lower than the lower end of the sealing plate 44. Then, the wastewater after the removal of heavy metal ions enters the upper end of the sealing plate 51 through the filter plate 43, the two rectangular grooves 37 and the filter screen 371, waiting to remove the soluble organic matter therein.

[0072] Similarly, the rotation of slide bar 4 511 along the inner surface of limit groove 6 36 and limit groove 5 35, and its cooperation with inclined block 3 361, inclined groove 3 362 and stop block 3 351 are exactly the same as the above cooperation principle, and will not be described in detail in this scheme;

[0073] Similarly, the cooperation between slide bar 2 425 and limit groove 2 32, limit groove 1 31, inclined block 1 311, inclined groove 1 312, and stop block 1 321 is exactly the same as the above cooperation principle, and this scheme will not elaborate on its operation process.

[0074] When the rotating roller 22 drives the ring 41 and the collection box 42 to rotate in the forward direction, causing the slide rod 425 to rotate along the inner surface of the limiting groove 32, the push plate 424 cooperates to collect the heavy metal precipitate at the upper end of the filter plate 43. When the rotating roller 22 drives the ring 41 and the collection box 42 to rotate in the reverse direction, causing the slide rod 425 to rotate along the inner surface of the limiting groove 31, the slide rod 423 cooperates with the baffle 421 and the limiting block 15 to release the heavy metal precipitate inside the collection box 42 to the inner surface of the collection box 13 through the through hole 14.

[0075] Therefore, this solution uses the limiting mechanism 3 in conjunction with the forward and reverse rotation of the motor 21 and the rotating roller 22. When the rotating roller 22 rotates forward, it can treat the wastewater to be treated by removing heavy metal ions with the sealing plate 44 and the filter plate 43, while simultaneously collecting heavy metal ion precipitates. It can also discharge the treated wastewater containing organic matter and heavy metal ions through the sealing plate 51, two rectangular troughs 38, and the filter screen 381. When the rotating roller 22 rotates in reverse, the wastewater that has had heavy metal ions removed can flow to the next stage for the removal of organic matter, and it can also achieve the effect of discharging the heavy metal ion precipitates. This not only improves the overall efficiency of wastewater treatment for chemical products, but also increases the flexibility of wastewater treatment, making the separation and discharge of wastewater and precipitates more efficient.

[0076] It should be noted that the specific installation method of the motor 21, the circuit connection method, and the control method used in this invention are all conventional designs, and will not be described in detail here.
