Description

Technical Field

[0001] This invention belongs to the field of waste liquid treatment technology, specifically a waste liquid treatment device for the preparation of rice blast amide. Background Technology

[0002] Isoprothiolane is a phenoxyamide fungicide used to control rice blast disease. It inhibits the formation of melanin in rice blast fungus by inhibiting the activity of cytosporine dehydrogenase in the melanin biosynthesis pathway. This mechanism gives isoprothiolane systemic and specific properties, allowing it to be absorbed by various parts of rice and accumulate in leaf tissues to exert its efficacy.

[0003] The preparation of rice blast amide generates some waste liquid, which mainly includes saline wastewater, organic solvent wastewater, and wastewater containing rice blast amide intermediates and by-products. The activated sludge method is usually used to treat the waste liquid biologically, through the action of microorganisms to remove organic matter from the wastewater and achieve the purpose of purifying the water quality.

[0004] When using the activated sludge process to treat wastewater generated from the preparation of rice blast amide, the wastewater contains harmful substances such as cyanide-containing wastewater, which can easily lead to excessively high concentrations. While the activated sludge process is suitable for treating low-concentration wastewater, the sludge is easily affected by toxic substances when the wastewater concentration is too high. Currently, wastewater treatment devices for rice blast amide preparation are unable to neutralize and dilute excessively concentrated wastewater, which can easily affect the treatment effect on the wastewater from rice blast amide preparation.

[0028] 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.

[0029] like Figures 1 to 4As shown in the embodiment of the present invention, a waste liquid treatment device for the preparation of rice blast amide includes a treatment base 1; a first frame 11 and a second frame 12 are respectively fixedly connected to the top two sides of the treatment base 1; a rotating shaft 111 is rotatably connected to the first frame 11; a first connecting block 13 is fixedly connected to the rotating shaft 111, and the first connecting block 13 is placed on the first frame 11 and can slide upwards against the inner wall of the first frame 11; a servo motor 14 is fixedly connected inside the first connecting block 13; a treatment cylinder 15 is fixedly connected to the output end of the servo motor 14, and the treatment cylinder 15 has an inlet and an outlet opposite to each other, and a plurality of water injection holes are opened on the treatment cylinder 15; the treatment... A guide tube 18 is fixedly connected to the treatment cylinder 15, and multiple water injection holes are located at the treatment cylinder 15. A water conveying frame 16 is rotatably connected to the end of the guide tube 18 away from the first connecting block 13. Two water guide pipes 17 are fixedly connected to the water conveying frame 16, and the two water guide pipes 17 can respectively connect to the multiple water injection holes of the treatment cylinder 15 through the water conveying frame 16 and the guide tube 18. A second connecting block 19 is fixedly connected to the end of the water conveying frame 16 away from the guide tube 18, and the second connecting block 19 is placed on the second frame 12. The second connecting block 19 can slide upward on the inner wall of the second frame 12. A flow control component is provided at each of the multiple water injection holes of the treatment cylinder 15. The flow control component is used to control the water guide pipes 17 to inject water into the treatment cylinder 15.The waste liquid treatment device for the preparation of rice blast amide uses a treatment base 1 as the main frame. A first frame 11 and a second frame 12 are erected on opposite sides of the upper surface of the treatment base 1. A first connecting block 13 is rotatably connected to the first frame 11 in conjunction with a rotating shaft 111. The output end of the servo motor 14 inside the first connecting block 13 is connected to one end of the treatment cylinder 15. A second connecting block 19 is placed on the second frame 12. A gap exists between the end of the second connecting block 19 away from the treatment cylinder 15 and the inner wall of the second frame 12, used to tilt the treatment cylinder 15 by pulling the second connecting block 19 upwards. The other end of the treatment cylinder 15 is rotatably connected to the outer wall of the water conveying frame 16 on the second connecting block 19 via a guide tube 18. Two water pipes 17 are connected to external water pumps to supply water to the guide tube 18 and the treatment cylinder 15 through the water pipes 17 and the water conveying frame 16. This is used to treat the waste liquid generated during the preparation of rice blast amide using the activated sludge method. During waste liquid treatment, the outlet of the treatment cylinder 15 is first sealed, and the waste liquid is injected into the cylinder 15 through the inlet. The concentration of the injected waste liquid needs to be detected. After the injection is completed, the inlet of the treatment cylinder 15 is also sealed. The output of the servo motor 14 drives the treatment cylinder 15 to rotate. The external water pump pumps water into the two water guide pipes 17 according to the detected waste liquid concentration. The water is sprayed into the guide cylinder 18 through the water conveying frame 16. As the flow control component controls the water to be sprayed into the interior of the treatment cylinder 15 through multiple water injection holes, the high-concentration waste liquid is neutralized and diluted. As the treatment cylinder 15 is continuously stirred, the neutralization and dilution effect of the waste liquid is improved. At the same time, after the waste liquid is neutralized and diluted, one end of the second connecting block 19 can be lifted. The treatment cylinder 15 rotates and tilts with the rotating shaft 111 connected to one end of the first connecting block 13, opening the outlet of the treatment cylinder 15, allowing the neutralized and diluted waste liquid to be discharged and collected, improving the waste liquid discharge effect.

[0030] The flow control assembly includes a sliding groove 2, a first sliding rod 21, and a counterweight 22. Multiple sliding grooves 2 are respectively opened in pairs at the water injection holes on the inner wall of the treatment cylinder 15. The first sliding rod 21 is slidably connected to the inner wall of the treatment cylinder 15. The counterweight 22 is fixedly connected to the two first sliding rods 21. When water is injected into the treatment cylinder 15 to neutralize and dilute the waste liquid, a water pump draws water into two water guide pipes 17. The water conveying frame 16, connected to the two water guide pipes 17, sprays water into the interior of the guide cylinder 18, and then the guide cylinder 18 injects water into multiple water injection holes of the treatment cylinder 15. If some water injection holes rotate to the top inner wall of the treatment cylinder 15, each counterweight 22... 2. With the two sliding rods 21 sliding down onto the inner walls of the two sliding grooves 2 respectively, the water injection hole at the sliding point of the counterweight 22 is open, and water can be injected into the treatment cylinder 15 from the guide tube 18 through the water injection hole. At the same time, multiple water injection holes on the bottom inner wall of part of the treatment cylinder 15 are blocked by multiple counterweights 22. Each counterweight 22 slides down the two sliding rods 21 due to gravity, so that the counterweight 22 blocks the water injection hole on the bottom inner wall of the treatment cylinder 15. Therefore, the water injection hole on the top inner wall of the treatment cylinder 15 is open, while the water injection hole on the bottom inner wall of the treatment cylinder 15 is blocked, which plays the role of controlling and blocking multiple water injection holes.

[0031] like Figures 1 to 3 As shown, a fixing rod 3 is fixedly connected to the middle of the second connecting block 19 and to the side near the processing cylinder 15, and the fixing rod 3 penetrates the interior of the processing cylinder 15; two stirring blades 31 are fixedly connected to the outer wall of the fixing rod 3, and multiple overflow holes are opened on the stirring blades 31; when the waste liquid and water are injected into the processing cylinder 15 for neutralization and dilution, the second connecting block 19 is placed on the second frame 12, and the fixing rod 3 is fixed to the second connecting block 19 in conjunction with the two stirring blades 31 and located inside the processing cylinder 15. As the output end of the servo motor 14 drives the processing cylinder 15 to rotate, the stirring blades 31 cooperate with the rotation of the processing cylinder 15 to stir the water and waste liquid to mix quickly, and the multiple overflow holes disperse and mix the waste liquid and water, thereby improving the neutralization and dilution effect of high-concentration waste liquid.

[0032] like Figures 1 to 5As shown, a filter cylinder 4 is slidably connected to the inner wall of the inlet of the treatment cylinder 15; two second-order sliding rods 41 are fixedly connected to the filter cylinder 4, and the two second-order sliding rods 41 are slidably connected to the inner wall of the treatment cylinder 15; an elastic element 42 is fixedly connected between the second-order sliding rods 41 and the inner wall of the treatment cylinder 15; a first-order filter screen plate 43 is fixedly connected to the inner wall of the filter cylinder 4; when the waste liquid is injected into the interior of the treatment cylinder 15 for neutralization and dilution, since the waste liquid is easily mixed with other raw materials and by-products, such as methyl isopropyl ketone and ammonium chloride, in addition to unreacted sodium cyanide, it may also contain other impurities, such as methyl isopropyl ketone and ammonium chloride, which will affect the subsequent treatment effect of the waste liquid. By using the filter cylinder 4 in conjunction with the two second-order sliding rods 41 slidably connected to the inlet of the treatment cylinder 15, when injecting liquid into the inlet, the filter cylinder 4 is first pressed down in conjunction with the two second-order sliding rods 41. The sliding rod 41 slides down the inner wall of the processing cylinder 15, and the two elastic elements 42 are squeezed and contracted under force. At this time, the filter cylinder 4 slides down, causing the first filter screen plate 43 to pass over the inner wall of the processing cylinder 15 and be located in the neutralized cavity of the processing cylinder 15. The liquid inlet is in the open state, and liquid is injected into the interior of the filter cylinder 4. The waste liquid is filtered by the first filter screen plate 43, leaving impurities inside the filter cylinder 4. The filtered waste liquid reaches the neutralized cavity of the processing cylinder 15 for use, which plays a role in pre-treatment of waste liquid. At the same time, after the liquid injection is completed, the pressing of the filter cylinder 4 is stopped, and the two elastic elements 42 push the filter cylinder 4 on the two second sliding rods 41 upward and slide. The first filter screen plate 43 slides upward on the inner wall of the processing cylinder 15, sealing the liquid inlet of the processing cylinder 15, which plays a role in controlling and sealing the liquid inlet of the processing cylinder 15.

[0033] like Figures 1 to 6 As shown, a second filter plate 5 is fixedly attached to the inner wall of the filter cylinder 4 near the bottom of the first filter plate 43, and the diameter of the holes in the second filter plate 5 is larger than that in the first filter plate 43. A third filter plate 51 is fixedly attached to the inner wall of the filter cylinder 4 below the second filter plate 5, and the diameter of the holes in the third filter plate 51 is the same as that in the first filter plate 43. When pre-treating waste liquid, the second filter plate 5 is fixed to the inner wall of the filter cylinder 4 to divide the interior of the filter cylinder 4. The lower layer of the second filter plate 5 can collect the filtered impurities, and together with the third filter plate 51, the waste liquid in the impurities is discharged. The upper layer of the second filter plate 5 can quickly filter the waste liquid. Through the layered treatment of the second filter plate 5, the probability of the first filter plate 43 being blocked by filtered impurities can be reduced.

[0034] A rotating rod 6 is rotatably connected to the central end of the second filter plate 5; a spiral blade 61 is fixedly attached to the outer wall of the end of the rotating rod 6; a scraper 62 is fixedly attached to the bottom outer wall of the rotating rod 6, and the scraper 62 can adhere to the wall scraper of the first filter plate 43 and the second filter plate 5; during the pretreatment of the injected waste liquid, the waste liquid injection flushing spiral blade 61 is used in conjunction with the rotating rod 6 rotating on the second filter plate 5, and the rotating rod 6 synchronously drives the scraper 62 to scrape the wall scraper of the first filter plate 43, reducing the situation where the first filter plate 43 is blocked by impurities and affecting filtration. At the same time, the scraper 62 can adhere to the upper surface scraper of the second filter plate 5, reducing the adhesion of impurities on the second filter plate 5.

[0035] like Figures 1 to 5 As shown, an electric slider 7 is slidably connected to the inner wall of the first frame 11 and above the rotating shaft 111; a fixing plate 71 is fixed to the outer wall of the electric slider 7; a connecting cylinder 72 is fixed to the inner wall of the fixing plate 71 and is located above the filter cylinder 4; when waste liquid is injected into the inlet of the treatment cylinder 15, the electric slider 7 drives the fixing plate 71 to slide down onto the inner wall of the first frame 11, the top of the connecting cylinder 72 is connected to the pipe for conveying waste liquid, and the connecting cylinder 72 presses against the filter cylinder 4 as the fixing plate 71 slides down, so that the filter cylinder 4 slides down to open the inlet of the treatment cylinder 15, and then begins to inject liquid into the filter cylinder 4. After the liquid injection is completed, the electric slider 7 drives the connecting cylinder 72 to slide up, and the filter cylinder 4 is pushed up and reset by the elastic force of the two elastic elements 42, which plays the role of automatically controlling and sealing the inlet of the treatment cylinder 15.

[0036] like Figures 1 to 3As shown, a hydraulic cylinder 81 is fixedly connected to the second frame 12 above the second connecting block 19; a connecting rope 82 is fixedly connected to the output end of the hydraulic cylinder 81; a fixing ring 83 is fixedly connected to the upper surface of the second connecting block 19, and the connecting rope 82 is sleeved on the fixing ring 83; after the waste liquid is neutralized and diluted, the first connecting block 13 and the second connecting block 19 are respectively limited by the first frame 11 and the second frame 12 with their respective U-shaped inner walls. When the treatment cylinder 15 is placed horizontally, the two sides of the first connecting block 13 are attached to the inner wall of the first frame 11 and placed on the first frame 11, and the two sides of the second connecting block 19 are attached to the second frame. The inner wall of 12 is placed on the second connecting block 19. The output end of the hydraulic cylinder 81 retracts, driving the fixed ring 83 connected to the connecting rope 82 to lift up. The fixed ring 83 simultaneously drives one end of the treatment cylinder 15 connected to the second connecting block 19 to lift up. The other end of the treatment cylinder 15 cooperates with the rotating shaft 111 connected to the first connecting block 13 to rotate the angle, thereby tilting the treatment cylinder 15. Then the liquid outlet of the treatment cylinder 15 is opened, and the waste liquid flows down from the liquid outlet along the inner wall of the treatment cylinder 15. After the liquid is discharged, the output end of the hydraulic cylinder 81 is lowered, and the second connecting block 19 is reset to continue the liquid injection and neutralization, which plays the role of discharging the neutralized waste liquid in the treatment cylinder 15.

[0037] An annular frame 9 is fixed to the outer wall of the first frame 11; a sliding plate 91 is installed on the side of the annular frame 9 near the processing cylinder 15; a rubber plate 92 is fixed to the end of the sliding plate 91 away from the annular frame 9, and the rubber plate 92 can block the liquid outlet of the processing cylinder 15; an elastic column 93 is fixed to the outer wall of the processing cylinder 15, and the end of the elastic column 93 away from the processing cylinder 15 is fixed to the sliding plate 91; when controlling the blocking of the liquid outlet of the processing cylinder 15, the annular frame 9 is fixed to the first frame 11 as a support for the sliding plate 91, the rubber plate 92 is fixed at one end of the sliding plate 91 and fits against the inclined liquid outlet of the processing cylinder 15, and the elastic column 93 holds the sliding plate 91 in place. 1 is connected to the processing cylinder 15. The elastic column 93 can also be replaced with a hinged telescopic rod. As the output end of the servo motor 14 drives the processing cylinder 15 to rotate, the other end of the sliding plate 91 connected to the elastic column 93 slides in a ring on the ring frame 9. This serves to seal the inclined liquid outlet of the processing cylinder 15 when the processing cylinder 15 rotates. At the same time, when the waste liquid is discharged from the liquid outlet, the end of the processing cylinder 15 away from the liquid outlet is lifted, causing the processing cylinder 15 to tilt. The liquid outlet of the processing cylinder 15 squeezes the rubber plate 92 to open the liquid outlet, and the neutralized and diluted waste liquid is discharged from the liquid outlet, which serves to control and seal the liquid outlet of the processing cylinder 15.

[0038] like Figures 1 to 4As shown, multiple guide plates 94 are fixedly attached to the inner wall of the treatment cylinder 15; the upper surface of the guide plate 94 is sloped; when waste liquid and water are injected into the treatment cylinder 15 for neutralization and dilution, the output end of the servo motor 14 drives the treatment cylinder 15 to rotate, and the multiple guide plates 94 fixedly attached to the inner wall of the treatment cylinder 15 guide the flow of the mixed waste liquid inside the treatment cylinder 15. The mixed waste liquid is flushed and mixed along the slope of the multiple guide plates 94, which improves the neutralization and dilution effect of the waste liquid.

[0039] Working process: When treating the waste liquid generated from the preparation of rice blast amide, the treatment base 1 serves as the main frame of the waste liquid treatment device. Frame 11 and Frame 12 are respectively erected on both sides of the upper surface of the treatment base 1. Connecting block 13 is rotatably connected to frame 11 in conjunction with rotating shaft 111. The output end of the servo motor 14 inside connecting block 13 is connected to one end of the treatment cylinder 15. Connecting block 19 is placed on frame 12. A gap exists between the end of connecting block 19 away from the treatment cylinder 15 and the inner wall of frame 12, which is used to pull connecting block 19 upwards to tilt the treatment cylinder 15. The other end of the treatment cylinder 15 is rotatably connected to connecting block 12 via guide tube 18. On the outer wall of the water conveying frame 16 on block 19, two water guide pipes 17 are connected to external water pumps for supplying water to the guide cylinder 18 and the treatment cylinder 15 through the water guide pipes 17 and the water conveying frame 16. When treating the waste liquid generated from the preparation of rice blast amide using the activated sludge method, the outlet of the treatment cylinder 15 is first sealed, and the waste liquid is injected into the inside of the treatment cylinder 15 from the inlet. The concentration of the injected waste liquid needs to be detected. After the injection is completed, the inlet of the treatment cylinder 15 is also sealed. The output of the servo motor 14 drives the treatment cylinder 15 to rotate. The external water pump pumps water into the two water guide pipes 17 according to the detected waste liquid concentration. The water is sprayed into the guide cylinder 18 from the water conveying frame 16. As the flow control component controls the water to be sprayed into the treatment cylinder through multiple water injection holes... Inside the treatment cylinder 15, the high-concentration waste liquid is neutralized and diluted. As the treatment cylinder 15 continuously agitates, the neutralization and dilution effect is enhanced. After neutralization and dilution, one end of the second connecting block 19 can be lifted, causing the treatment cylinder 15 to rotate and tilt along with the rotating shaft 111 connected to one end of the first connecting block 13. This opens the outlet of the treatment cylinder 15, allowing the neutralized and diluted waste liquid to be collected, improving the waste liquid discharge efficiency. When water is injected into the treatment cylinder 15 to neutralize and dilute the waste liquid, a water pump draws water into the two water guide pipes 17. The water conveying frame 16, connected to the two water guide pipes 17, sprays water into the interior of the guide cylinder 18, and then the guide cylinder 18 injects water into multiple water injection holes in the treatment cylinder 15. If partial injection occurs... When the water hole rotates to the top inner wall of the treatment cylinder 15, each counterweight 22, together with two sliding rods 21, slides down onto the inner wall of the two sliding grooves 2. At this time, the water injection hole at the point where the counterweight 22 slides down is open, and water can be injected into the treatment cylinder 15 from the guide tube 18 through the water injection hole. At the same time, multiple water injection holes on the bottom inner wall of part of the treatment cylinder 15 are blocked by multiple counterweights 22. Each counterweight 22 slides down the two sliding rods 21 due to gravity, so that the counterweight 22 blocks the water injection hole on the bottom inner wall of the treatment cylinder 15. Therefore, the water injection hole on the top inner wall of the treatment cylinder 15 is open, while the water injection hole on the bottom inner wall of the treatment cylinder 15 is blocked, which plays the role of controlling and blocking multiple water injection holes.

[0040] When both waste liquid and water are injected into the treatment cylinder 15 for neutralization and dilution, the second connecting block 19 is placed on the second frame 12. The fixing rod 3, together with two stirring blades 31, is fixed on the second connecting block 19 and located inside the treatment cylinder 15. As the output end of the servo motor 14 drives the treatment cylinder 15 to rotate, the stirring blades 31, together with the rotation of the treatment cylinder 15, stir the water and waste liquid to mix quickly. With the help of multiple overflow holes, the waste liquid and water are dispersed and mixed, improving the neutralization and dilution effect of high-concentration waste liquid.

[0041] When waste liquid is injected into the treatment cylinder 15 for neutralization and dilution, impurities are easily mixed into the waste liquid, affecting the subsequent treatment effect. The filter cylinder 4, in conjunction with two sliding rods 41, is slidably connected to the inlet of the treatment cylinder 15. When injecting liquid into the inlet, the filter cylinder 4, along with the two sliding rods 41, is first pressed down to slide down the inner wall of the treatment cylinder 15. The two elastic elements 42 are compressed and contracted, causing the filter cylinder 4 to slide down and pull the first filter screen 43 across the inner wall of the treatment cylinder 15 to the neutralization cavity. The inlet is open, and liquid is injected into the filter cylinder 4. The waste liquid is filtered by the first filter screen 43, leaving impurities inside the filter cylinder 4. The filtered waste liquid is then used in the neutralization cavity of the treatment cylinder 15, serving as a pretreatment for the waste liquid. Simultaneously, after the injection is complete, the pressing of the filter cylinder 4 is stopped, and the two elastic elements 42 push the filter cylinder 4 on the two sliding rods 41 upwards, causing the first filter screen 43 to slide upwards. The inner wall of the treatment cylinder 15 seals the liquid inlet of the treatment cylinder 15, thus controlling and sealing the liquid inlet of the treatment cylinder 15. When pre-treating waste liquid, the second filter plate 5 is fixed to the inner wall of the filter cylinder 4 to divide the interior of the filter cylinder 4. The lower layer of the second filter plate 5 can collect the filtered impurities, and together with the third filter plate 51, the waste liquid in the impurities is discharged. The upper layer of the second filter plate 5 can quickly filter the waste liquid. Through the stratified treatment of the second filter plate 5, This can reduce the probability of the No. 1 filter screen plate 43 being clogged by impurities; during the pretreatment of the injected waste liquid, the waste liquid injection flushing spiral blade 61 is used in conjunction with the rotating rod 6 to rotate on the No. 2 filter screen plate 5. The rotating rod 6 then drives the scraper 62 to scrape the wall of the No. 1 filter screen plate 43, reducing the situation where the No. 1 filter screen plate 43 is clogged by impurities and affects filtration. At the same time, the scraper 62 can fit against the upper surface scraper of the No. 2 filter screen plate 5 to reduce the adhesion of impurities on the No. 2 filter screen plate 5.

[0042] When waste liquid is injected into the inlet of the treatment cylinder 15, the electric slider 7 drives the fixing plate 71 to slide down onto the inner wall of the first frame 11. The top of the connecting cylinder 72 is connected to the pipe for conveying waste liquid. As the fixing plate 71 slides down, the connecting cylinder 72 presses against the filter cylinder 4, causing the filter cylinder 4 to slide down and open the inlet of the treatment cylinder 15. Then, liquid is injected into the filter cylinder 4. After the liquid injection is completed, the electric slider 7 drives the connecting cylinder 72 to slide up, and the filter cylinder 4 is pushed up and reset by the elastic force of the two elastic elements 42, which plays the role of automatically controlling and sealing the inlet of the treatment cylinder 15.

[0043] After the waste liquid is neutralized and diluted, the first connecting block 13 and the second connecting block 19 are respectively limited by the first frame 11 and the second frame 12 with their respective U-shaped inner walls. When the treatment cylinder 15 is placed horizontally, the two sides of the first connecting block 13 are attached to the inner wall of the first frame 11 and placed on the first frame 11, and the two sides of the second connecting block 19 are attached to the inner wall of the second frame 12 and placed on the second connecting block 19. The output end of the hydraulic cylinder 81 retracts, which drives the fixing ring 83 connected to the connecting rope 82 to lift up. The fixed ring 83 synchronously drives one end of the treatment cylinder 15 connected to the second connecting block 19 to be lifted. The other end of the treatment cylinder 15 cooperates with the rotating shaft 111 connected to the first connecting block 13 to rotate the angle, thereby tilting the treatment cylinder 15. Then the liquid outlet of the treatment cylinder 15 is opened, and the waste liquid flows down from the liquid outlet along the inner wall of the treatment cylinder 15. After the liquid is discharged, the output end of the hydraulic cylinder 81 is lowered, and the second connecting block 19 is reset so that the liquid injection and neutralization can continue, which plays the role of discharging the neutralized waste liquid in the treatment cylinder 15.

[0044] When the outlet of the treatment cylinder 15 is blocked, the ring frame 9 is fixed on the first frame 11 as a support for the sliding plate 91. The rubber plate 92 is fixed at one end of the sliding plate 91 and fits against the inclined outlet of the treatment cylinder 15. The elastic column 93 connects the sliding plate 91 to the treatment cylinder 15. The elastic column 93 can also be replaced by a hinged telescopic rod. As the output end of the servo motor 14 drives the treatment cylinder 15 to rotate, the other end of the sliding plate 91 connected to the elastic column 93 slides in a ring on the ring frame 9. This serves to block the inclined outlet of the treatment cylinder 15 when the treatment cylinder 15 rotates. At the same time, when the waste liquid is discharged from the outlet, the end of the treatment cylinder 15 away from the outlet is lifted, causing the treatment cylinder 15 to tilt. The outlet of the treatment cylinder 15 squeezes the rubber plate 92 to open the outlet, and the neutralized and diluted waste liquid is discharged from the outlet, thus controlling and blocking the outlet of the treatment cylinder 15.

[0045] When waste liquid and water are injected into the treatment cylinder 15 for neutralization and dilution, the output end of the servo motor 14 drives the treatment cylinder 15 to rotate. Multiple guide plates 94 fixed on the inner wall of the treatment cylinder 15 guide the flow of the mixed waste liquid inside the treatment cylinder 15. The mixed waste liquid is flushed and mixed along the slope of the multiple guide plates 94, which improves the neutralization and dilution effect of the waste liquid.
