DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1, as Figure 1 and Figure 2 As shown, a sewage 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 arranged in the middle of the rotating mechanism 2 on the inner surface of the treatment tank 1, a stirring mechanism 5 is arranged in the lower middle of the rotating mechanism 2 on the inner surface of the treatment tank 1, and an ultrafiltration membrane 6 is fixedly connected to the lower part of the inner surface of the treatment tank 1.

[0033] After the production of chemical products, the discharged wastewater generally contains heavy metal ions, organic matter and some solid sediments. After the wastewater passes through the basic filtration and sedimentation, the wastewater generated by the manufacture of chemical products is transported to the inside of the treatment tank 1 to remove the heavy metal ions and soluble organic matter. During the transportation process, the precipitant of heavy metal ions is added to the inner surface of the treatment tank 1;

[0034] Inside the treatment tank 1, the scraping mechanism 4 is driven to rotate by the rotating mechanism 2, wherein the scraping mechanism 4 cooperates with the limiting mechanism 3 to first stir the sewage, and then the scraping mechanism 4 can collect the precipitate precipitated by the heavy metal ions, and then the precipitate collected by the scraping mechanism 4 is discharged from the treatment tank 1 through the cooperation of the rotating mechanism 2, and at the same time, the sewage with heavy metal ions removed falls to the upper end of the stirring mechanism 5 after passing through the partial structure of the scraping mechanism 4, and then the coagulation precipitant of organic matter is released above the stirring mechanism 5 through the cooperation of the stirring mechanism 5 and the treatment tank 1;

[0035] Then, the rotating mechanism 2 cooperates with the stirring mechanism 5 to continuously stir when the organic coagulant precipitant is first added to help the organic coagulant precipitant and the sewage to be fully mixed. After sufficient mixing, the rotating mechanism 2 is no longer running to allow the sewage and the organic coagulant precipitant to fully react. Subsequently, the rotating mechanism 2 cooperates with the stirring mechanism 5 and the limiting mechanism 3 to filter and discharge the sewage without organic matter to the upper end of the ultrafiltration membrane 6. At the same time, the stirring mechanism 5 scrapes and collects the precipitated organic matter. After the treatment is completed, the sewage is uniformly treated. After the heavy metal ions and organic matter are removed, the sewage slowly passes through the ultrafiltration membrane 6 into the bottom wall of the inner surface of the treatment tank 1, and can then be transported out for the next step of detection and sterilization. After the detection meets the standards, the sewage can be discharged.

[0036] The ultrafiltration membrane 6 mentioned above is of conventional design in the prior art, and its main purpose is to cooperate with the stirring mechanism 5 to completely remove organic matter in the sewage.

[0037] See also Figure 1 and Figure 2 A feed inlet 11 is provided on one side of the upper end of the treatment tank 1, a discharge port 16 is provided in the middle of the lower end of the treatment tank 1, a through hole 14 is provided on one side of the middle and upper part of the inner surface of the treatment tank 1, a collecting box 13 is fixedly connected to the outer surface of the treatment tank 1 outside the through hole 14, a limiting block 15 is fixedly connected to the inner surface of the treatment tank 1 above the through hole 14, and a coagulant box 17 is symmetrically fixedly connected to the middle and lower part of the outer surface of the treatment tank 1.

[0038] The sewage removed by preliminary filtration is transported to the inner surface of the treatment tank 1 through the feeding port 11 by the conveying device in the prior art. At the same time, quantitative transportation is carried out each time during the transportation process. In the process of being transported to the inner surface of the treatment tank 1 through the feeding port 11, the heavy metal ion precipitant is sent to the upper part of the inner surface of the treatment tank 1 according to the transported amount. The rotating mechanism 2 cooperates with the scraping mechanism 4 and the limiting mechanism 3 to mix the sewage. After the heavy metal ion precipitation is completed, the heavy metal precipitate collected by the structure of the scraping mechanism 4 is released to the inner surface of the collecting box 13 through the scraping mechanism 4 in cooperation with the through hole 14 and the limiting block 15. When the sewage falls into the upper end of the stirring mechanism 5 to prepare for removing organic matter in the sewage, the two coagulant boxes 17 on both sides release a quantitative amount of organic coagulant precipitant to the upper part of the stirring mechanism 5, and the auxiliary stirring mechanism 5 coagulates and precipitates the organic matter in the sewage. Subsequently, the sewage after coagulation and precipitation is filtered again through the ultrafiltration membrane 6 and released through the discharge port 16, and the treated sewage is subjected to the next step of detection and discharge.

[0039] During the operation of this embodiment, the limiting mechanism 3 cooperates with the scraping mechanism 4 to fully stir the wastewater during the removal of heavy metal ions, and on the other hand, the precipitated heavy metal precipitates can be collected and discharged to avoid the precipitates from affecting subsequent filtration treatment. At the same time, the limiting mechanism 3 cooperates with the stirring mechanism 5 to not only precipitate organic matter through forward rotation, but also filter the wastewater without organic matter through reverse rotation, thereby improving the utilization rate and flexibility of the equipment. At the same time, the stirring mechanism 5 and the ultrafiltration membrane 6 cooperate together to remove organic matter in the wastewater more thoroughly, further improving the efficiency of wastewater treatment.

[0040] Embodiment 2: Based on Embodiment 1, this embodiment can achieve the effect of removing heavy metal ions from the wastewater to be treated and collecting heavy metal ion precipitates at the same time, and can also discharge the wastewater treated with organic matter and heavy metal ions.

[0041] See also Figure 2 The rotating mechanism 2 includes a motor 21 fixedly connected to the middle of the upper end of the processing tank 1, and a roller 22 is fixedly connected to the output end of the motor 21. The roller 22 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 by the manufacture of chemical products, the motor 21 is activated so that its output end drives the roller 1 22 to rotate forward or reverse at the same time, thereby cooperating with the scraping mechanism 4 and the stirring mechanism 5 to achieve different functions.

[0043] See also Figure 6The scraping mechanism 4 includes a filter plate 43 rotatably connected to the middle part of the outer surface of the roller 22, a ring 41 is slidably connected to the middle and upper part of the outer surface of the roller 22, a collecting box 42 is fixedly connected to one side of the outer surface of the ring 41, the bottom end of the collecting box 42 is tightly attached to the upper end of the filter plate 43, and a sealing plate 44 is slidably connected to the middle and lower part of the outer surface of the roller 22.

[0044] Specifically, when the sewage to be treated and the heavy metal ion precipitant enter the upper inner surface of the treatment tank 1 from the feed port 11, the motor 21 is excited to make its output end rotate forward, thereby driving the roller 22 to rotate forward. When the roller 22 rotates forward, the ring 41 is driven by the collecting box 42 to slide down to the upper end of the filter plate 43, and the sealing plate 44 slides up to be tightly attached to the lower end of the filter plate 43. Then the roller 22 continues to rotate, so that the ring 41 drives the collecting box 42 to rotate, and the sewage is continuously stirred to ensure that the heavy metal ion precipitant and the sewage are fully reacted and mixed. At the same time, the heavy metal precipitate precipitated by the reaction is collected in the collecting box 42 during the stirring process. At the same time, due to the cooperation between the sealing plate 44 and the filter plate 43, the sewage 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 described 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 gap, solid particles can only be on the surface and will not get stuck in the pores.

[0046] See also Figure 7 The collecting box 42 is slidably connected to a baffle plate 421 on one side close to the inner surface of the processing tank 1, an L-shaped rod 422 is fixedly connected to the upper end of the baffle plate 421, a slide bar 1 423 is fixedly connected to the upper part of the vertical part of the L-shaped rod 422 close to the inner surface of the processing tank 1, the collecting box 42 is fixedly connected to a slide bar 2 425 on the lower part close to the inner surface of the processing tank 1, a push plate 424 is fixedly connected to one side of the collecting box 42, an outer surface of the slide bar 2 425 is slidably connected to the inner surface of the limiting groove 2 32, a slide bar 3 441 is fixedly connected to the outer surface of the sealing plate 1 44, and an outer surface of the slide bar 3 441 is slidably connected to the inner surface of the limiting groove 4 34.

[0047] Furthermore, when the roller 22 drives the ring 41 and the sealing plate 44 to rotate forwardly, the sealing plate 44 cooperates with the filter plate 43 to seal the filter plate 43 during the forward rotation, so that the sewage and the heavy metal ion precipitant are fully reacted and mixed. During the rotation, the ring 41 drives the collecting box 42 to rotate. During the rotation of the collecting box 42, the heavy metal precipitate deposited on the upper end of the filter plate 43 enters the collecting box 42 through the pushing plate 424 through the setting of the pushing plate 424. At the same time, the baffle 421 cooperates with the collecting box 42 to seal the heavy metal precipitate inside the collecting box 42.

[0048] Furthermore, when the output end of the motor 21 drives the circular ring 1 41 and the sealing plate 1 44 to reverse, the sealing plate 1 44 slides downward for a distance through the cooperation of the sliding rod 3 441, and at the same time, during the reverse process of the circular ring 1 41, the sliding rod 2 425 cooperates with the collecting box 2 42 to make the collecting box 2 42 and the circular ring 1 41 slide upward for a distance as a whole, at this time, the filter plate 43 and the sealing plate 1 44 are no longer tightly attached, and the sewage after the heavy metal ions are removed can slowly flow to the upper end of the stirring mechanism 5;

[0049] See also Fig.10 , and then during the process of the roller 1 22 driving the collecting box 2 42 and the ring 1 41 to reverse, when the slide bar 1 423 is driven to rotate until it is in close contact with one side of the arc surface of the upper end of the limit block 15, as the slide bar 1 423 moves, the arc setting of the limit block 15 causes the slide bar 1 423 to gradually move upward, and then the L-shaped rod 422 and the baffle 421 will move upward at the same time. At this time, the collecting box 2 42 is no longer in a sealed state, and then the heavy metal sediment inside the collecting box 2 42 moves with the collecting box 2 4 2 rotates and moves to the side close to the baffle 421. As the baffle 421 moves upward, the heavy metal sediment flows along the inner surface of the through hole 14 to the inner surface of the collecting box 13 and is collected. Then, as the slide bar 1 423 descends along the arc surface of the limit block 15, the baffle 421 is gradually driven to seal the collecting box 2 42. Then, the roller 1 22 drives the ring 1 41 and the collecting box 2 42 to continuously reverse, so that the heavy metal sediment inside the collecting box 2 42 enters the inner surface of the collecting box 1 13 through the through hole 14.

[0050] See also Figure 8 , Fig. 9 and Fig.10 The stirring mechanism 5 includes a sealing plate 21 51 which is slidably connected to the middle and lower part of the outer surface of the roller 22, a gear 2 57 is fixedly connected to the middle part of the upper end of the sealing plate 21, 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, a plurality of rollers 2 56 are rotatably connected to the lower end of the horizontal plate 55, and a collecting box 3 58 is fixedly connected to one side of the horizontal plate 55.

[0051] See also Fig.10 When the roller 1 22 rotates forward, the sealing plates 2 51 and 52 are located at the upper middle and lower part of the inner surface of the treatment tank 1. During the reverse rotation of the roller 1 22, the sewage after the heavy metal ions are removed passes through the filter plate 43 and the sealing plate 1 44 and falls above the sealing plate 2 51. At this time, the sealing plate 2 51 is located at the lower middle and lower part of the inner surface of the treatment tank 1. At this time, the telescopic rod 54 is stretched, and the gear 2 57 descends with the sealing plate 2 51. At the same time, 59 and the horizontal plate 55, the collecting box 3 58 and the plurality of rollers 2 56 move downward by the same distance at the same time;

[0052] At this time, the two coagulant boxes 17 cooperate to release a certain amount of organic coagulant precipitant to 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 removed of 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, roller 1 22 reverses, and sealing plate 2 51 is driven by roller 1 22 to reverse, and gear 2 57 is driven to rotate at the same time, and gear 59 and cross plate 55 are used to make several rollers 2 56 run at the same time. During the reversal of sealing plate 2 51, several rollers 2 56 continuously mix and stir the sewage and organic coagulant precipitant on the upper end of sealing plate 2 51 to make them fully mixed, and at the same time help to disperse the organic coagulant precipitant. After rotating for a period of time, the motor 21 is suspended, and then the sealing plate 2 51 stops rotating. At this time, the collecting box 2 42 is also no longer driven to rotate. During the period when the motor 21 is suspended, the sewage and the organic coagulant precipitant are given sufficient reaction time to convert the soluble organic matter in the sewage into precipitate.

[0054] See also Figure 8 A gear 561 is fixedly connected to the middle and lower parts of the outer surfaces of several rollers 2 56, the gear 1 561 close to the side of roller 1 22 is meshed with gear 2 57, several gears 561 are meshed with each other, and brushes 562 are fixedly connected to the lower ends of several gears 1 561, and the lower ends of several brushes 562 are tightly attached to the upper end of sealing plate 2 51.

[0055] When the sealing plate 2 51 is driven by the roller 1 22 to rotate in the reverse direction, the sealing plate 2 51 drives the gear 2 57 to rotate in the same direction, and then through the cooperation with the gear 1 561 on the side close to the roller 1 22 and the cooperation between the gears 1 561, when the sealing plate 2 51 and the gear 2 57 are reversed, the gears 1 561 are driven to rotate at the same time, thereby realizing the simultaneous rotation of the brushes 562 and the roller 2 56, and the sewage on the upper end of the sealing plate 2 51 and the organic coagulant precipitant can be mixed during the rotation of the brushes 562;

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

[0057] See also Fig. 9 The outer surface of the sealing plate 2 51 is fixedly connected with a sliding rod 4 511, and the outer surface of the sliding rod 4 511 is slidably connected to the inner surface of the limiting groove 6 36. The side of the collecting box 3 58 away from the horizontal plate 55 is fixedly connected with a scraper 581, and 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 precipitant fully reacts with the sewage, and the soluble organic matter in the sewage is converted into precipitate and precipitates and remains below the wastewater. The motor 21 is then stimulated to make the output end of the motor 21 rotate forward, which will cause the sealing plate 2 51 to rise a certain distance. While the sealing plate 2 51 moves upward, it drives a number of brushes 562, the collecting box 3 58, the horizontal plate 55, and the gear 2 57 to move in the same direction. After rising a certain distance, the motor 21 is stopped immediately. During the upward movement of the sealing plate 2 51, the collecting box 3 58 and the horizontal plate 55 will not make the sewage after the reaction turbid, that is, some precipitates are driven up and will soon settle on the upper end of the sealing plate 2 51.

[0059] Furthermore, when the sealing plate 51 rises for a certain distance and pauses, the sewage with soluble organic matter removed from the upper end of the sealing plate 51 slowly flows to the top of the ultrafiltration membrane 6, and is filtered again by the ultrafiltration membrane 6 to remove the organic matter in the sewage more cleanly, and then the treated sewage is tested and discharged through the discharge port 16.

[0060] See also Figure 3 The limiting mechanism 3 includes a limiting groove 1 31 opened in the middle and upper part of the inner surface of the processing tank 1, a limiting groove 2 32 opened on the inner surface of the processing tank 1 below the limiting groove 1 31, a limiting groove 4 34 opened in the middle part of the inner surface of the processing tank 1, a limiting groove 33 opened on the inner surface of the processing tank 1 below the limiting groove 4 34, a limiting groove 6 36 opened in the middle and lower part of the inner surface of the processing tank 1, a limiting groove 5 35 opened on the inner surface of the processing tank 1 below the limiting groove 6 36, a rectangular groove 1 37 symmetrically opened in the middle part of the inner surface of the processing tank 1, and a rectangular groove 2 38 symmetrically opened in the middle and lower part of the inner surface of the processing tank 1.

[0061] Specifically, when the sewage generated by the manufacture of chemical products is transported to the inner surface of the treatment tank 1, the limiting groove 1 31 and the limiting groove 2 32 as well as the limiting groove 33 and the limiting groove 4 34 cooperate with the slide rod 3 441 to achieve the stirring and mixing of heavy metal ions in the sewage and the collection of heavy metal precipitates, and the release of the sewage after the heavy metal ions are removed to the upper end of the sealing plate 2 51, and the release of the collected heavy metal precipitates, so as to avoid affecting the next treatment of heavy metal ions in the sewage.

[0062] Similarly, the limiting groove five 35 and the limiting groove six 36 cooperate with the sliding rod four 511 to process the organic matter in the sewage, and cooperate with the coagulant precipitant released by the two coagulant boxes 17 to precipitate the organic matter in the sewage.

[0063] See also Figure 3The bottom wall of the inner surface of the limiting groove 1 31 is provided with an inclined groove 1 312 penetrating to the top wall of the inner surface of the limiting groove 2 32, and one side of the lower part of the inner surface of the inclined groove 1 312 is rotatably connected with a stopper 1 321, and the upper side of the inner surface of the inclined groove 1 312 away from the stopper 1 321 is rotatably connected with the inclined block 1 311, and the bottom wall of the inner surface of the limiting groove 4 34 is provided with an inclined groove 2 342 penetrating to the top wall of the inner surface of the limiting groove 3 33, and one side of the lower part of the inner surface of the inclined groove 2 342 is rotatably connected with the stopper 2 331, and the upper side of the inner surface of the inclined groove 2 342 away from the stopper 2 331 is rotatably connected with the inclined block Two 341, an elastic roller 343 is fixedly connected between the lower part of the upper end of the inclined block two 341 and the processing tank 1, the bottom wall of the inner surface of the limiting groove six 36 is provided with an inclined groove three 362 that penetrates to the top wall of the inner surface of the limiting groove five 35, one side of the lower part of the inner surface of the inclined groove three 362 is rotatably connected to the stopper three 351, and the upper side of the inner surface of the inclined groove three 362 away from the stopper three 351 is rotatably connected to the inclined block three 361, the two rectangular grooves one 37 are fixedly connected to the filter screen one 371 on the side close to each other, and the two rectangular grooves two 38 are fixedly connected to the filter screen two 381 on the side close to each other.

[0064] When the output end of the motor 21 rotates forward to drive the roller 1 22 to rotate forward, the slide bar 2 425 rotates along the inner surface of the limit groove 2 32, and the slide bar 3 441 rotates along the inner surface of the limit groove 4 34. At this time, the sealing plate 1 44 is in close contact with the top wall and the bottom wall of the inner surface of the limit groove 4 34.

[0065] See also Figure 5 When the roller 1 22 rotates forward, the slide bar 4 511 rotates along the inner surface of the limiting groove 6 36. At the same time, the sealing plate 2 51 is in close contact with the top wall and the bottom wall of the inner surface of the limiting groove 6 36. Part of the rectangular groove 2 38 is located at the upper end of the sealing plate 2 51, and the other part is located at the lower end of the sealing plate 2 51. Therefore, when the roller 1 22 rotates forward and drives the sealing plate 2 51 to rise to be in close contact with the inner surface of the limiting groove 6 36, the rotation is stopped. At this time, the sewage with organic matter removed from the upper end of the sealing plate 2 51 flows to the upper end of the ultrafiltration membrane 6 through the two rectangular grooves 2 38 on both sides and the filter screen 2 381.

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

[0067] See also Figure 4When the roller 1 22 rotates forward, the sealing plate 1 44 rotates, thereby causing the sliding bar 3 441 to rotate along the inner surface of the limiting groove 4 34. When the sliding bar 3 441 rotates to contact the upper end of the inclined block 2 341, the sliding bar 3 441 continues to rotate, pressing the inclined block 2 341 downward to stretch the elastic roller 343. When the sliding bar 3 441 rotates away from the inclined block 2 341 and continues to rotate on the inner surface of the limiting groove 4 34, the elastic roller 343 drives the inclined block 2 341 to reset.

[0068] Furthermore, when the roller 1 22 is driven to reverse, thereby driving the sealing plate 1 44 and the sliding bar 3 441 to reverse along the inner surface of the limiting groove 4 34, the sliding bar 3 441 rotates to the lower end of the inclined block 2 341, and the inclined block 2 341 is set to make the sliding bar 3 441 move downward along the inclined groove 2 342 and slide through the inner surface of the inclined groove 2 342 to the inner surface of the limiting groove 33. As the sealing plate 1 44 and the sliding bar 3 441 rise and fall at the same time, the roller 1 22 drives the sealing plate 1 44 to continue to reverse, so that the filter plate 43 is separated from the sealing plate 1 44.

[0069] Similarly, when the roller 1 22 drives the sealing plate 1 44 to reverse, the sliding bar 3 441 reverses along the inner surface of the limiting groove 3 33. When it rotates to the lower end of the stopper 2 331, the sliding bar 3 441 continues to reverse and pushes the stopper 2 331 upward, and then the sliding bar 3 441 continues to reverse. When the roller 1 22 is driven to rotate forward, the sliding bar 3 441 rotates along the inner surface of the limiting groove 3 33 to the upper end of the stopper 2 331. Through the setting of the stopper 2 331, the sealing plate 1 44 and the sliding bar 3 441 rotate forward along the upper end of the stopper 2 331 into the inner surface of the inclined groove 2 342 and then into the inner surface of the limiting groove 4 34 to rotate forward.

[0070] In this way, the motor 21 drives the roller 22, the sealing plate 44 and the sliding rod 441 to achieve the effect that the forward rotating sealing plate 44 is tightly attached to the filter plate 43, and the reverse rotating sealing plate 44 is separated from the filter plate 43.

[0071] See also Figure 5 When the roller 22 drives the sealing plate 44 and the sliding rod 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 parts of the two rectangular grooves 37 are higher than the upper end of the sealing plate 44, and the lower parts of the rectangular grooves 37 are lower than the lower end of the sealing plate 44. Then, the sewage after the heavy metal ions are removed passes through the filter plate 43, the two rectangular grooves 37 and the filter screen 371 into the upper end of the sealing plate 2 51, waiting for the removal of soluble organic matter therein.

[0072] Similarly, the sliding rod 4 511 rotates along the inner surface of the limiting groove 6 36 and the limiting groove 5 35 and cooperates with the inclined block 3 361 and the inclined groove 3 362 and the stopper 3 351 in the same manner as the above-mentioned cooperation principle, and will not be described in detail in this solution;

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

[0074] When the roller 22 drives the ring 41 and the collecting box 42 to rotate forward so that the slide bar 425 rotates along the inner surface of the limiting groove 32, the push plate 424 cooperates to collect the heavy metal precipitate on the upper end of the filter plate 43. When the roller 22 drives the ring 41 and the collecting box 42 to rotate reversely, the slide bar 425 rotates along the inner surface of the limiting groove 31. At this time, the slide bar 423 cooperates with the baffle 421 and the limiting block 15 to release the heavy metal precipitate inside the collecting box 42 through the through hole 14 to the inner surface of the collecting box 13.

[0075] Therefore, in this solution, the limiting mechanism 3 is used to coordinate the forward and reverse rotation of the motor 21 and the roller 22 as a whole. When the roller 22 rotates forward, the sewage to be treated can be processed with the sealing plate 44 and the filter plate 43 to remove heavy metal ions and collect heavy metal ion precipitates at the same time, and the sewage treated with organic matter and heavy metal ions can be discharged through the sealing plate 51, the two rectangular grooves 38 and the filter screen 381. When the roller 22 is reversed, the sewage with heavy metal ions removed can be flowed to the next stage for organic matter removal, and the heavy metal ion precipitates can be discharged. This not only improves the overall sewage treatment efficiency generated by chemical products, but also increases the flexibility of sewage treatment, making the separation and discharge of sewage 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 the present invention are all conventional designs and will not be elaborated in detail in the present invention.
