Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to an acidic wastewater purification device for oxadiazon production. Background Technology

[0002] In the purification and separation process of oxadiazon products, it is usually necessary to use acids or acidic solutions for washing, extraction, and other operations to remove impurities and unreacted raw materials. These acidic washing or extraction solutions eventually become part of the wastewater, increasing its acidity.

[0003] In existing technologies, sodium hydroxide solution is typically added to acidic wastewater to allow the acidic substances in the wastewater to react fully with the sodium hydroxide solution. However, precipitates are easily generated during the reaction process, and when the precipitates are separated from the treated wastewater, the precipitates can easily clog the separation equipment, thereby reducing the effectiveness of the separation equipment.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an acidic wastewater purification device for the production of oxadiazon to overcome the above-mentioned technical problems existing in the existing related technologies.

[0034] Please see Figures 1-6 As shown, this utility model is an acidic wastewater purification device for oxadiazon production, including a cylindrical body 1:

[0035] The cylinder 1 is respectively equipped with a loading and unloading assembly 2, a driving assembly 3, a stirring assembly 4, a sealing assembly 5, and a filtering assembly 6;

[0036] The loading and unloading assembly 2 is connected to the interior of the cylinder 1 so that the loading and unloading assembly 2 can load and unload materials into the cylinder 1.

[0037] The output end of the drive component 3 is fixedly installed at one end of the stirring component 4 so that the drive component 3 drives the stirring component 4 to stir the acidic wastewater.

[0038] The sealing component 5 is internally connected to the interior of the stirring component 4, so that the sealing component 5 can seal the discharge end of the stirring component 4;

[0039] The outer surface of the filter assembly 6 is fixedly connected to the inner wall of the cylinder 1 so that the filter assembly 6 can filter the wastewater purified inside the stirring assembly 4.

[0040] In use, acidic wastewater is poured into the cylinder 1 through the loading and unloading assembly 2. Since the outer surface of the stirring assembly 4 is fixedly connected to the inner wall of the cylinder 1, the wastewater entering the cylinder 1 can enter the stirring assembly 4. Then, the purification liquid is added into the stirring assembly 4 through the loading and unloading assembly 2. The stirring assembly 4 installed at the output end is driven to rotate by the start drive assembly 3 so that the wastewater and the purification liquid can react quickly and fully. After the reaction is completed, the sealing assembly 5 is activated to release the seal on the stirring assembly 4, so that the wastewater and the precipitate after the reaction can flow through the sealing assembly 5 to the top of the filter assembly 6. As the stirring assembly 4 continues to rotate, it can drive the filter assembly 6 to rotate, so as to collect and treat the precipitate accumulated at the top of the filter assembly 6. The filtered wastewater flows out through the loading and unloading assembly 2 for subsequent treatment.

[0041] This invention drives the stirring assembly 4 installed at the output end of the drive assembly 3 to rotate, so that the wastewater and the purification liquid react quickly and fully. After the reaction is completed, the sealing assembly 5 is activated to release the seal on the stirring assembly 4, so that the wastewater and the precipitate after the reaction can flow through the sealing assembly 5 to the top of the filter assembly 6. As the stirring assembly 4 continues to rotate, it can drive the filter assembly 6 to rotate, so as to concentrate the precipitate accumulated at the top of the filter assembly 6 for treatment, thereby avoiding the accumulation of precipitate and clogging of the filter assembly 6, and ensuring the stability of the acidic wastewater purification device for oxadiazon production during use.

[0042] In one embodiment, the loading and unloading assembly 2 includes a first loading pipe 201, a second loading pipe 202, and a discharge pipe 203. The bottom ends of the first loading pipe 201 and the second loading pipe 202 are fixedly connected to the top end of the cylinder 1, and the top end of the discharge pipe 203 is fixedly connected to the bottom end of the cylinder 1.

[0043] Acidic wastewater is fed into the mixing assembly 4 through the first feeding pipe 201 along with the cylinder 1, while purified liquid is fed into the mixing assembly 4 through the second feeding pipe 202. The discharge pipe 203 can discharge the filtered wastewater.

[0044] In one embodiment, the drive component 3 includes a motor 301, the bottom end of which is fixedly installed with the top end of the cylinder 1, and a connecting shaft 302 is fixedly installed at the output end of the motor 301.

[0045] The starting motor 301 drives the connecting shaft 302 mounted on the output end to rotate, so as to provide stable power to the connecting shaft 302.

[0046] In one embodiment, the stirring assembly 4 includes a stirring tank 401, the outer surface of which is fixedly connected to the inner wall of the cylinder 1, a rotating shaft 402 is rotatably arranged inside the stirring tank 401, the top end of the rotating shaft 402 is fixedly installed to the bottom end of the connecting shaft 302, and a stirring blade 403 is fixedly installed on the outer surface of the rotating shaft 402.

[0047] The motor 301 drives the connecting shaft 302 installed at the output end to rotate, thereby driving the rotating shaft 402 installed at the bottom to rotate. Since the outer surface of the rotating shaft 402 is rotated with the inside of the mixing tank 401, and the outer surface of the rotating shaft 402 is fixedly installed with the stirring blade 403, when the rotating shaft 402 rotates, it can drive the stirring blade 403 to rotate around the mixing tank 401 as the center, so that it can stir the acidic wastewater and purification liquid inside the mixing tank 401, thereby accelerating the reaction time between the acidic wastewater and the purification liquid.

[0048] In one embodiment, the sealing component 5 includes a connecting frame 501, the top end of which is fixedly connected to the bottom end of the mixing tank 401, an electric push rod 502 is fixedly installed on one side of the connecting frame 501, and a connecting plate 503 is fixedly installed on the telescopic end of the electric push rod 502.

[0049] The sealing component 5 also includes a limiting groove 504, which is formed inside the connecting frame 501. A sealing plate 505 is slidably disposed inside the limiting groove 504, and one side of the sealing plate 505 is fixedly connected to one side of the connecting plate 503.

[0050] The connecting plate 503 installed at the telescopic end is moved by activating the electric push rod 502, which in turn moves the sealing plate 505 fixed on one side. Since the outer surface of the sealing plate 505 is slidably set with the inside of the limiting groove 504, and the limiting groove 504 is opened inside the connecting frame 501, when the sealing plate 505 moves, it can move along the direction of the limiting groove 504, thereby opening and closing the connection frame 501 and the mixing tank 401, so as to seal and discharge the wastewater and sediment inside the mixing tank 401.

[0051] In one embodiment, the filter assembly 6 includes a filter screen 601, the outer surface of which is fixedly connected to the inner wall of the cylinder 1, a scraper 602 is attached to the top of the filter screen 601, the interior of the scraper 602 is fixedly installed to the outer surface of the rotating shaft 402, and a discharge hopper 603 is fixedly connected to the bottom of the filter screen 601.

[0052] When the rotating shaft 402 rotates, it drives the scraper 602 mounted on its outer surface to rotate at the top of the filter screen 601, so that it scrapes the sediment accumulated at the top of the filter screen 601 and moves it into the discharge hopper 603 and discharges it, thereby preventing the filter screen 601 from accumulating too much sediment and becoming clogged.

[0053] Through the above technical solution, 1. The stirring component 4 installed at the output end is driven by the start-up drive component 3 to rotate, so that the wastewater and the purification liquid react quickly and fully. After the reaction is completed, the sealing component 5 is started to release the seal on the stirring component 4, so that the wastewater and the precipitate after the reaction can flow through the sealing component 5 to the top of the filter component 6. As the stirring component 4 continues to rotate, it can drive the filter component 6 to rotate, so as to concentrate the precipitate accumulated at the top of the filter component 6 for treatment, thereby avoiding the accumulation of precipitate and clogging of the filter component 6, and ensuring the stability of the acidic wastewater purification device for oxadiazon production during use.

[0054] 2. The connecting plate 503 installed at the telescopic end is moved by starting the electric push rod 502, so that it drives the sealing plate 505 fixed on one side to move. Since the outer surface of the sealing plate 505 is slidably set with the inside of the limiting groove 504, and the limiting groove 504 is opened inside the connecting frame 501, when the sealing plate 505 moves, it can move along the direction of the limiting groove 504, thereby opening and closing the connection frame 501 and the mixing tank 401, so as to seal and discharge the wastewater and sediment inside the mixing tank 401.
