Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wastewater treatment, and particularly relates to a wastewater treatment equipment and method for sterilizing pesticide production. BACKGROUND

[0002] The wastewater generated in the production of sterilizing pesticides contains various pollutants, which usually have the characteristics of high concentration, high toxicity and difficult biodegradation, contain various organic and inorganic pollutants, and often contain high-concentration salt in the wastewater, which may come from raw materials or reaction conditions in the production process. The high-concentration salt cannot be directly discharged and needs to be desalted. The commonly used method is heat treatment, which evaporates water and leaves salt by heating the waste liquid.

[0003] When using heat treatment for desalination, the air inside the evaporation cavity needs to be pumped out to form a negative pressure state inside, so as to reduce the boiling point of the liquid and reduce energy consumption. The traditional treatment equipment directly discharges salt crystals from the inside of the evaporation cavity after the liquid is evaporated, which will destroy the air pressure state in the evaporation cavity, so that the air needs to be pumped again to form a negative pressure state during the next production process. Therefore, a wastewater treatment equipment and method for sterilizing pesticide production are provided. SUMMARY

[0004] To solve the problem of salt crystals being directly discharged from the inside of the evaporation cavity, which destroys the air pressure state in the evaporation cavity, the application provides a wastewater treatment equipment and method for sterilizing pesticide production.

[0007] Preferably, the stirring assembly includes a transmission rod rotatably connected inside the heating tank body and a first motor fixedly connected to the top of the heating tank body. Multiple support frames are spirally distributed outside the transmission rod, and vertical scrapers are slidably connected inside each support frame. A traction rod is hinged to one side of the vertical scraper located inside the support frame. A scraping frame is sleeved outside the transmission rod, and a support ring is rotatably connected to the top of the scraping frame. A bottom scraper is fixedly connected to the bottom of the transmission rod, and a first telescopic rod is annularly distributed at the top of the support ring.

[0008] Preferably, the top of the transmission rod is provided with teeth, and a gear is fixedly connected to the output end of the first motor. The teeth on the top of the transmission rod mesh with the gear. The transmission rod is located inside the evaporation chamber. The vertical scraper abuts against the inner wall of the heating tank body. At the same time, the bottom surface of the upper vertical scraper and the top surface of the adjacent lower vertical scraper are coplanar in the horizontal direction.

[0009] Preferably, the scraping frame has scraping rings arranged linearly in the middle, each scraping ring corresponding to a position of a traction rod and hinged to the traction rod. The scraping frame is slidably connected to the support frame. The support ring abuts against the inner wall of the heating tank body. The bottom scraper abuts against the bottom sealing plate. The bottom sealing plate abuts against the partition plate and has the same specifications. The end of the first telescopic rod away from the support ring is fixedly connected to the heating tank body.

[0010] Preferably, the pressure regulating component includes a limiting support rod movably connected inside the heating tank body, a second telescopic rod fixedly connected to the top of the limiting support rod, a ventilation channel opened inside the limiting support rod, a communication port opened at one end of the limiting support rod located at the bottom of the transmission rod, a third telescopic rod fixedly connected to the bottom of the ventilation channel, a sealing block fixedly connected to the output end of the third telescopic rod, and a vent hole opened at one end of the limiting support rod located at the bottom of the bottom sealing plate.

[0011] Preferably, the limiting support rod is slidably connected inside the transmission rod, and the top of the transmission rod extends through the top sealing plate and the heating tank body to the top of the heating tank body. The second telescopic rod is fixedly connected to the main support. The two ends of the limiting support rod are rotatably connected to the top sealing plate and the bottom sealing plate, respectively. The sealing block is located below the air guide hole.

[0012] Preferably, the top sealing plate is located above the transmission rod, the bottom sealing plate is located below the partition plate and is engaged with the partition plate, and the bottom sealing plate and the second motor are located inside the collection chamber.

[0013] Preferably, the second motor is rotatably connected to the main body of the heating tank, the bottom of the second motor is fixedly connected to the salt-pushing scraper, and the top of the second motor is slidably connected to the limiting support rod.

[0014] A method for treating wastewater from the production of bactericidal pesticides includes the following steps: S1. The second telescopic rod pulls the limiting support rod upward, causing the limiting support rod to pull the bottom sealing plate to move, so that the bottom sealing plate and the partition plate are locked together. Then, high-salt waste liquid is transported into the heating tank body through the feed port. Then, air is drawn out from the heating tank body through the suction device connected to the air extraction port to make the evaporation chamber a negative pressure state. S2. When the main body of the heating tank draws air from the inside of the evaporation chamber, the third telescopic rod pulls the sealing block downward to connect the air guide hole with the ventilation channel, so that the evaporation chamber and the collection chamber are connected through the ventilation channel, the connecting port and the air guide hole, so that the air extraction port simultaneously draws air from the inside of the collection chamber, and simultaneously draws the inside of the collection chamber into a negative pressure state. S3. The high-salt waste liquid is heated by the main body of the heating tank. At the same time, water vapor is continuously drawn in through the exhaust port. Simultaneously, the first motor drives the transmission rod to rotate, which in turn drives the support frame and the vertical scraper to rotate, thereby agitating the high-salt waste liquid and scraping off the salt crystals condensed on the inner wall of the heating tank. At the same time, the one-way valve at the feed port is opened to replenish the high-salt waste liquid into the heating tank. Meanwhile, the first telescopic rod extends and retracts periodically, which drives the scraping frame to move up and down through the support ring. The scraping ring scrapes off the salt crystals condensed on the outer surface of the transmission rod. At the same time, the scraping frame pulls the vertical scraper to move through the traction rod, causing the vertical scraper to slide from inside the support frame and scrape off the salt crystals on the surface of the vertical scraper. S4. After the salt solution has evaporated and crystallized, the third telescopic rod pushes the sealing block upward to block the air vent. Then, the second telescopic rod pushes the limiting support rod downward to release the bottom sealing plate from the partition plate, allowing the salt crystals to be pushed into the collection chamber by the bottom scraper. Then, the second telescopic rod pulls the limiting support rod to reset, closing the bottom sealing plate and partition plate. While maintaining the temperature and negative pressure inside the evaporation chamber, the salt crystals are discharged.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention facilitates the separation of the evaporation chamber and the collection chamber by setting up a bottom sealing plate and a partition plate, thus avoiding disruption of the gas pressure state of the evaporation chamber when crystals are discharged. The second telescopic rod drives the limiting support rod to move, which can move the bottom sealing plate to engage or separate from the partition plate, allowing the salt crystals to be entered into the collection chamber by the bottom scraper. The bottom sealing plate can engage and close with the partition plate to separate the evaporation chamber and the collection chamber. Salt crystals are discharged while maintaining a constant temperature and negative pressure state inside the evaporation chamber. This invention, through the combination of a vertical scraper and a scraping frame, facilitates the scraping of salt crystals on the inner wall of the evaporation chamber while preventing salt crystals from adhering to the scraper. By driving the transmission rod to rotate the support frame and the vertical scraper, the high-salt waste liquid is agitated, and the condensed salt crystals on the inner wall of the heating tank are scraped off. At the same time, the first telescopic rod periodically extends and retracts, driving the scraping frame to move up and down through the support ring. The scraping ring scrapes off the salt crystals condensed on the outer surface of the transmission rod. Simultaneously, the scraping frame pulls the vertical scraper through the traction rod, causing the vertical scraper to slide from inside the support frame and scrape off the salt crystals on the surface of the vertical scraper. This invention, through the combination of a pressure regulating component and a bottom sealing plate, facilitates the adjustment of the pressure state inside the evaporation chamber and the collection chamber to be consistent. When air is drawn from inside the evaporation chamber through the air extraction port, the evaporation chamber and the collection chamber are connected through the air guide hole and the air passage, so that the main body of the heating tank simultaneously draws air from inside the collection chamber, creating a negative pressure state inside the collection chamber. This ensures that the air pressure inside the evaporation chamber remains constant when salt crystals enter the collection chamber from the evaporation chamber. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, the present invention provides a wastewater treatment device for the production of bactericidal pesticides, including a main support 1, an evaporation component 2 fixedly connected inside the main support 1, a stirring component 3 and a pressure regulating component 4 disposed inside the evaporation component 2, a top sealing plate 5 and a bottom sealing plate 6 movably connected inside the evaporation component 2, a partition plate 7 fixedly connected inside the evaporation component 2, a second motor 8 disposed at the bottom of the main support 1, and a salt pushing scraper 9 fixedly connected to the output end of the second motor 8. The evaporation assembly 2 includes a heating tank body 21 fixedly connected to the main support 1. The top and bottom of the heating tank body 21 are respectively fixedly connected to an air extraction port 22 and a material outlet 24. The middle part of the heating tank body 21 is fixedly connected to a material inlet 23. The interior of the heating tank body 21 is divided into an evaporation chamber 25 and a collection chamber 26. A heating jacket is provided inside the heating tank body 21. The air extraction port 22 is connected to a suction device. The material inlet 23 is connected to a raw material tank. A one-way valve is provided in the middle of the material inlet 23. The material inlet 23 is connected to the evaporation chamber 25. The air extraction port 22 passes through the top sealing plate 5 and is connected to the evaporation chamber 25. The material outlet 24 is connected to the collection chamber 26.

[0020] The above scheme is adopted as follows: by setting up the evaporation component 2, the waste liquid is heated by the heating jacket set inside the heating tank body 21. At the same time, air and water vapor are drawn in through the air extraction port 22 to keep the inside of the heating tank body 21 under negative pressure. The feed inlet 23 set in the middle of the heating tank body 21 can continuously replenish the waste liquid inside the heating tank body 21. By setting up the evaporation chamber 25 and the collection chamber 26 inside the heating tank body 21, the temperature and negative pressure can be maintained when the salt crystals inside the heating tank body 21 are discharged.

[0021] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the stirring assembly 3 includes a transmission rod 31 rotatably connected inside the heating tank body 21 and a first motor 32 fixedly connected to the top of the heating tank body 21. Multiple support frames 33 are spirally distributed outside the transmission rod 31. Vertical scrapers 34 are slidably connected inside each support frame 33. A traction rod 35 is hinged to one side of the vertical scraper 34 inside the support frame 33. A scraping frame 36 is sleeved outside the transmission rod 31. A support ring 37 is rotatably connected to the top of the scraping frame 36. A bottom scraper 38 is fixedly connected to the bottom of the transmission rod 31. A first telescopic rod 39 is distributed in a ring on the top of the support ring 37.

[0022] The above scheme is adopted as follows: By setting the stirring assembly 3, the first motor 32 can drive the transmission rod 31 to rotate, and the transmission rod 31 drives the support frame 33 and the vertical scraper 34 to rotate, so as to stir the heated waste liquid. When the transmission rod 31 rotates, the first telescopic rod 39 synchronously extends and retracts periodically, and the scraping frame 36 moves up and down through the support ring 37, so that the scraping ring set in the middle of the scraping frame 36 scrapes off the salt crystals condensed on the outer surface of the transmission rod 31. While the scraping frame 36 moves, the traction rod 35 moves synchronously with the scraping frame 36, thereby pulling the vertical scraper 34 to move horizontally back and forth, so that the vertical scraper 34 slides back and forth inside the support frame 33 to scrape off the salt crystals on the surface of the vertical scraper 34. At the same time, the bottom scraper 38 rotates continuously to scrape off the salt crystals on the top of the bottom sealing plate 6 and the partition plate 7.

[0023] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the top of the transmission rod 31 is provided with teeth, and the output end of the first motor 32 is fixedly connected to a gear. The teeth on the top of the transmission rod 31 mesh with the gear. The transmission rod 31 is located inside the evaporation chamber 25. The vertical scraper 34 abuts against the inner wall of the heating tank body 21. At the same time, the bottom surface of the upper vertical scraper 34 and the top surface of the adjacent lower vertical scraper 34 are coplanar in the horizontal direction. The scraping frame 36 is provided with scraping rings arranged linearly in the middle. The scraping rings correspond to the positions of the traction rod 35 and are hinged to the traction rod 35. The scraping frame 36 is slidably connected to the support frame 33. The support ring 37 abuts against the inner wall of the heating tank body 21. The bottom of the bottom scraper 38 abuts against the bottom sealing plate 6. The bottom sealing plate 6 abuts against the partition plate 7 and is of the same specification. The end of the first telescopic rod 39 away from the support ring 37 is fixedly connected to the heating tank body 21.

[0024] The above scheme is adopted as follows: the teeth set at the top of the transmission rod 31 and the gear set at the output end of the first motor 32 facilitate the first motor 32 to drive the transmission rod 31 to rotate. The vertical scraper 34 can scrape off the salt crystals on the inner wall of the heating tank body 21 and stir the waste liquid at the same time, so that the solution is in a flowing state, reducing the probability of the formation of large crystals. The edges of the vertical scrapers 34 are set to overlap to avoid scraping dead corners. The scraping ring can scrape off the salt crystals on the outer wall of the transmission rod 31. At the same time, the limiting groove opened in the middle of the scraping frame 36 allows the support frame 33 to slide inside the limiting groove, so that when the support frame 33 rotates, it will drive the scraping frame 36 to rotate synchronously.

[0025] like Figure 5 , Figure 7 and Figure 8 As shown, the pressure regulating component 4 includes a limiting support rod 41 movably connected inside the heating tank body 21. A second telescopic rod 42 is fixedly connected to the top of the limiting support rod 41. A ventilation channel 43 is opened inside the limiting support rod 41. A connecting port 44 is opened at one end of the limiting support rod 41 located at the bottom of the transmission rod 31. A third telescopic rod 45 is fixedly connected to the bottom of the ventilation channel 43. A sealing block 46 is fixedly connected to the output end of the third telescopic rod 45. A vent hole 47 is opened at one end of the limiting support rod 41 located at the bottom of the bottom sealing plate 6. The limiting support rod 41 is slidably connected inside the transmission rod 31, and the top of the transmission rod 31 extends through the top sealing plate 5 and the heating tank body 21 to the top of the heating tank body 21. The second telescopic rod 42 is fixedly connected to the main support 1. The two ends of the limiting support rod 41 are rotatably connected to the top sealing plate 5 and the bottom sealing plate 6, respectively. The sealing block 46 is located below the vent hole 47.

[0026] The above scheme is adopted as follows: By setting the pressure regulating component 4, the top sealing plate 5 and the bottom sealing plate 6 are moved synchronously by the limiting support rod 41. By setting the second telescopic rod 42, the up and down movement of the limiting support rod 41 can be easily controlled. The setting of the ventilation channel 43, the connecting port 44 and the air guide hole 47 can connect the evaporation chamber 25 and the collection chamber 26 when the bottom sealing plate 6 and the partition plate 7 are in the closed state, so that the evaporation chamber 25 and the collection chamber 26 are kept in the same state. By setting the third telescopic rod 45 and the sealing block 46, when the discharge port 24 is opened to discharge salt crystals, the evaporation chamber 25 and the collection chamber 26 are disconnected, so that the evaporation chamber 25 is kept in a negative pressure state. After the salt crystals are discharged, the air guide hole 47 can be opened, and the air in the collection chamber 26 can be drawn in through the ventilation channel 43 by the air extraction port 22, so that the inside of the collection chamber 26 is adjusted to a negative pressure state again, so as to ensure that the negative pressure state inside the evaporation chamber 25 remains unchanged.

[0027] like Figure 2 , Figure 6 and Figure 7 As shown, the top sealing plate 5 is located on the upper side of the transmission rod 31, the bottom sealing plate 6 is located on the lower side of the partition plate 7 and is engaged with the partition plate 7, the bottom sealing plate 6 and the second motor 8 are located inside the collection chamber 26, the second motor 8 is rotatably connected to the heating tank body 21, the bottom of the second motor 8 is fixedly connected to the salt pushing scraper 9, and the top of the second motor 8 is slidably connected to the limiting support rod 41.

[0028] The above scheme is adopted: by setting the bottom sealing plate 6 and the partition plate 7, the evaporation chamber 25 and the collection chamber 26 can be easily separated. At the same time, the top sealing plate 5 is set so that the bottom sealing plate 6 moves up and down and the top sealing plate 5 moves up and down synchronously, so that the gas pressure inside the evaporation chamber 25 remains constant. The setting of the second motor 8 and the salt pushing scraper 9 allows the salt pushing scraper 9 to drive the second motor 8 to rotate and push the salt crystals out from the discharge port 24.

[0029] like Figures 1 to 8 As shown, this invention proposes a method for treating wastewater from the production of bactericidal pesticides, comprising the following steps: S1. The second telescopic rod 42 pulls the limiting support rod 41 to move upward, so that the limiting support rod 41 pulls the bottom sealing plate 6 to move, so that the bottom sealing plate 6 and the partition plate 7 are locked together. Then, the high-salt waste liquid is transported into the heating tank body 21 through the feed port 23. Then, the suction device connected to the air extraction port 22 draws air from the heating tank body 21 to the outside to make the evaporation chamber 25 a negative pressure state. S2. When the air is drawn from the inside of the evaporation chamber 25 through the air extraction port 22, the third telescopic rod 45 pulls the sealing block 46 downward to connect the air guide hole 47 with the ventilation channel 43, so that the evaporation chamber 25 and the collection chamber 26 are connected through the ventilation channel 43, the connecting port 44 and the air guide hole 47, so that the heating tank body 21 simultaneously draws air from the inside of the collection chamber 26, and draws the inside of the collection chamber 26 into a negative pressure state. S3. The high-salt waste liquid is heated by the heating tank body 21, while the air extraction port 22 continuously draws in water vapor. At the same time, the first motor 32 drives the transmission rod 31 to rotate, which in turn drives the support frame 33 and the vertical scraper 34 to rotate, thereby agitating the high-salt waste liquid and scraping off the salt crystals condensed on the inner wall of the heating tank body 21. Simultaneously, the one-way valve at the feed port 23 is opened to replenish the high-salt waste liquid into the heating tank body 21. At the same time, the first telescopic rod 39 extends and retracts periodically, which drives the scraping frame 36 to move up and down through the support ring 37. The scraping ring scrapes off the salt crystals condensed on the outer surface of the transmission rod 31. At the same time, the scraping frame 36 pulls the vertical scraper 34 to move through the traction rod 35, causing the vertical scraper 34 to slide from inside the support frame 33 and scrape off the salt crystals on the surface of the vertical scraper 34. S4. After the salt solution has evaporated and crystallized, the third telescopic rod 45 pushes the sealing block 46 upward to block the air guide hole 47. Then, the second telescopic rod 42 pushes the limiting support rod 41 downward to release the bottom sealing plate 6 and the partition plate 7 from their closed state. This allows the salt crystals to be pushed into the collection chamber 26 by the bottom scraper 38. Then, the second telescopic rod 42 pulls the limiting support rod 41 to reset, closing the bottom sealing plate 6 and the partition plate 7. Under the condition that the temperature and negative pressure inside the evaporation chamber 25 remain unchanged, the salt crystals are discharged.
